[0002] In recent years, the living standards of Chinese people have been continuously improving, and people's expectations and requirements for food have become higher and higher. Since Chinese people's cooking method is mostly stir-frying over high heat, the kitchen fumes are relatively large, and the current dynamic extraction interceptor has a low fume separation efficiency. Many fumes are not extracted by the dynamic extraction interceptor, or the separation rate of the fumes is low when they are separated by the dynamic extraction interceptor, resulting in a high content of solid-liquid mixture in the kitchen air during cooking, which is harmful to people's respiratory system. After cooking, the inside of the kitchen is covered with a layer of solid-liquid mixture in the fume, which brings inconvenience to people's daily life. Summary of the invention

[0075] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0076] Embodiment 1

[0077] Please also read Figures 1 to 4 , it should be known that, Figures 1 to 3The root of the intercepting fan blade is not shown in the figure. This embodiment 1 discloses an intercepting fan blade 1, which is a long strip fan blade and is provided with a protruding structure 1a for increasing the collision probability of oil smoke passing through the intercepting fan blade to extend the separation path of the oil smoke.

[0078] Specifically, the interception fan blade 1 refers to a long sheet structure that can be installed on the fixed plate of the separation plate, and when the fixed plate rotates under the drive of an external force, it rotates along with the rotation of the fixed plate, thereby intercepting and separating the grease and / or solid mixture in the oil fume. Preferably, the interception fan blade 1 is a flat long strip structure. The purpose of using an interception fan blade with a flat long strip structure is: because the interception fan blade needs to rotate at a high speed to intercept the oil fume airflow, if the thickness of the interception fan blade is too large, it may affect the rotation speed of the interception fan blade, which may affect the effect of the interception fan blade in intercepting the oil fume airflow. Therefore, the interception fan blade of the present invention preferably adopts a flat long strip structure.

[0079] It should be known that when the intercepting fan blades 1 are installed on the fixed plate of the separation plate, in order to improve the oil fume separation efficiency, the number of intercepting fan blades 1 should be multiple, specifically 50 to 150 pieces, and a gap should be formed between two adjacent intercepting fan blades 1 so that the oil fume airflow can pass into the gap and contact the intercepting fan blades 1, thereby achieving the purpose of oil fume separation.

[0080] When the interception blades 1 are installed on the separation disk and the separation disk rotates at a certain speed, the oil fume airflow enters the separation disk from one side of the separation disk. When the oil fume airflow passes through the gap between adjacent interception blades 1, the grease, particles, etc. in the oil fume will collide with the side of the interception blades 1 on both sides of the gap between the interception blades 1 and be adsorbed on the side of the interception blades 1, and thrown out along the radial direction of the interception blades 1 to achieve the oil fume separation effect. In order to provide the power for the oil fume airflow to pass through the separation disk, a negative pressure fan can be provided to provide the power for sucking the oil fume, or the power for sucking the oil fume can be generated by the separation disk itself.

[0081] In this patent, due to the presence of a raised structure on the intercepting blade 1, when the oil fume airflow passes through the gap of the intercepting blade 1 of the separation disk, the oil fume airflow will pass through a longer distance compared to the blade without a raised structure, increasing the probability of contact between the oil fume, grease, and particles in the oil fume and the intercepting blade and increasing the path of the oil fume airflow through the separation disk to a certain extent, reducing the probability of the oil fume, grease, and particles in the oil fume passing directly through the gap of the intercepting blade 1 without being intercepted, thereby improving the intercepting blade 1's ability to collide and adsorb the oil and particles in the oil fume, and maximizing the oil fume separation effect. The raised structure on the intercepting blade 1 can adopt one or more minimum raised structure units, and the raised structure can be set at any position on the intercepting blade and adopt any structure, such as being set on the side, top or bottom of the intercepting blade, and any possible structure that can increase the probability of oil fume colliding with the intercepting blade when the oil fume airflow passes through the gap of the intercepting blade to extend the separation path of the oil fume belongs to the protection scope of this patent.

[0082] In the prior art, the blades of fluid equipment are as flat as possible so that working media such as gas and liquid can pass through the blades in the shortest time instead of extending the time it takes to pass through the blades. The blades of some fluid machinery even have strict restrictions on the roughness of their surfaces to ensure that gas, liquid, etc. can pass through the blades quickly. Therefore, providing a raised structure on the surface of the blade to increase the probability of the oil smoke airflow colliding with the intercepting blade and extending the path through the blade is not only not common knowledge in the art, but even a technical means that violates common knowledge in the art.

[0083] It should be known that the raised structure 1a of the present invention refers to: a structure arranged on the intercepting fan blade 1, which can increase the path of the oil smoke passing through the intercepting fan blade 1 when the oil smoke passes through the intercepting fan blade 1, for example, it can be a raised strip, a raised point, a raised column or other protrusions arranged on the intercepting fan blade 1.

[0084] like Figure 1 , Figure 2 As shown, in the present embodiment, the cross section of the intercepting blade 1 has one or more bends, one side of the cross section is the inner side of the intercepting blade 1, and the other side of the cross section is the outer side of the intercepting blade 1, and the inner side of the cross section may be provided with the convex structure. Specifically, since the intercepting blade is in the shape of an elongated strip, the cross section is a cross section along a length direction perpendicular to the intercepting blade 1, and the cross section may be any shape with bends, such as a V-shape, a W-shape, a polygon, or a Z-shape. For example, when the cross section is in the shape of a V-shape, it has a single bend; when the cross section is in the shape of a W-shape, it has three bends; when the cross section is in the shape of a polygon, such as a parallelogram, a rhombus, a square, a rectangle, a pentagon, a hexagon, an octagon, etc., it has at least four bends; when the cross section is in the shape of a Z-shape, it has two bends.

[0085] Generally, since a bend usually forms an angle, the inner side of the bend is usually one side of the angle space forming the angle, and the outer side of the bend is the side opposite to the inner side.

[0086] It can be known that when the protruding structure 1a is provided on the intercepting blade, the protruding structure can be provided on the inner side of the cross section of the intercepting blade 1 .

[0087] In this embodiment, the intercepting wind blade 1 includes a first blade part 11 and a second blade part 12 which are flat and long strips. The first blade part includes a first side surface 110 and a second side surface opposite to the first side surface 110. The second blade part includes a third side surface 120 and a fourth side surface opposite to the third side surface 120. The first side surface 110 of the first blade part and the third side surface 120 of the second blade part are connected, so that the cross-section of the intercepting wind blade 1 is a V-shaped cross-section. The concave side of the V-shaped cross-section is the inner side of the intercepting wind blade, and the other side corresponding to the concave side of the V-shaped cross-section is the outer side of the intercepting wind blade. Specifically, the first side surface 110 of the first blade part and the third side surface 120 of the second blade part substantially overlap, thereby forming the V-shaped cross section, while the second side surface of the first blade part is away from the first side surface 110, and the third side surface 120 of the second blade part is away from the fourth side surface, the surface of the first blade part is formed between the first side surface 110 and the second side surface, and the surface of the second blade part is formed between the third side surface 120 and the fourth side surface. As can be seen from the above, the protruding structure 1a can be provided on the inner side and / or outer side of the V-shaped cross section.

[0088] Among them, the first side surface 110 and the second side surface are the two sides of the width direction of the first blade part, the third side surface 120 and the fourth side surface are the two sides of the width direction of the second blade part, and when the first side surface 110 is connected to the third side surface 120, the first side surface 110 and the third side surface 120 completely overlap.

[0089] From the above, it can be seen that the inner side of the V-shape refers to the side of the V-shape forming an angle space, while the outer side of the V-shape is the side opposite to the inner side (such as Figure 2 shown).

[0090] Further, the protruding structure 1a is provided at the intersection of the first blade part 11 and the second blade part 12 and / or at the non-intersecting part of the first blade part 11 and / or the second blade part 12. Specifically, the first blade part and the second blade part are both long flat sheet-like parts.

[0091] Taking the case where the protruding structure 1a is disposed at the intersection of the first blade portion 11 and the second blade portion 12 as an example, the position of the protruding structure 1a on the intercepting blade 1 can be: the protruding structure 1a is disposed at the intersection of the first blade portion 11 and the second blade portion 12, and the protruding structure 1a is located on the inner side of the V-shape (such as Figure 3 shown);

[0092] The first embodiment of the present invention is preferably described by taking the case where the protruding structure 1 a is located at the inner side of the V-shape and is provided at the intersection of the first blade portion 11 and the second blade portion 12 as an example.

[0093] Specifically, when the intercepting fan blade 1 is installed on the fixed plate of the separation plate, the second blade part 12 is located above the first blade part 11 along the air intake direction of the oil smoke, that is, when the oil smoke passes through the intercepting fan blade 1, it first contacts the first blade part 11. Since the protruding structure 1a is not provided on other non-intersecting positions of the first blade part 11 (i.e., the surface of the first blade part 11), the oil smoke will pass through quickly. When the oil smoke continues to move upward along the surface of the first blade part 11 to the intersection position, the oil smoke is affected by the protruding structure 1a provided on the intersection, and the oil smoke continuously rotates at the intersection of the first blade part 11 and the second blade part 12, thereby forming a self-rotating flow field, where a large number of oil droplets gather until the oil droplets gather to a certain weight, and then the oil droplets are separated from the flow field and thrown out.

[0094] It can be seen that the design of arranging the raised structure 1a at the intersection of the first blade part 11 and the second blade part 12 and being located on the inner side of the V-shape can effectively extend the path of the oil smoke passing through the intersection, so that as many oil droplets as possible can be separated, preventing the oil smoke from quickly passing through the first blade part 11 and the second blade part 12 when the oil droplets are not separated, thereby effectively ensuring the oil smoke separation effect.

[0095] It should be known that the protruding structure 1a can be integrally formed at the intersection of the first blade portion 11 and the second blade portion 12, thereby simplifying the processing steps of the intercepting blade 1 and improving the processing efficiency. At the same time, the integral molding method can also avoid the situation where the protruding structure 1a adopts a split design and there may be gaps or additional parts, which may cause oil droplets to accumulate in the gaps or additional parts, which is not conducive to the cleaning of the intercepting blade 1.

[0096] Combination Figures 4 to 8As shown, in this embodiment, since the intercepting blade 1 is a long strip component, the two ends of the intercepting blade 1 are respectively the first end 111 and the second end 112, and the first end 111 and the second end 112 are respectively the two ends in the length direction of the intercepting blade 1, and the protruding structure 1a can be a long strip protrusion, and the protruding structure 1a extends from the first end 111 to the second end 112, or the length direction of the protruding structure 1a extends along the length direction of the intercepting blade 1, and the length of the protruding structure 1a is less than the length of the intercepting blade 1. Specifically, when the intercepting blade is applied to a separation disk and mounted to a fixing disk of the separation disk, the first end of the intercepting blade is preferably an end close to the center of the separation disk, and the second end of the intercepting blade is an end relatively far from the center of the separation disk.

[0097] As another optional embodiment, the raised structure is also a long strip, but the length of the raised structure 1a is less than the length of the intercepting blade 1. For example, the raised strip is only set at a position close to the first end of the intercepting blade 1, or is set from the first end to a position almost in the middle, or is only set at a position close to the second end, or is set from the second end to a position almost in the middle, etc. This method is mainly adopted because: when the intercepting blade 1 is used in the separation disk for oil fume interception, the number of intercepting blades 1 is large. When multiple intercepting blades are installed, the second end 112 of the intercepting blade is usually the first to contact the oil fume airflow, while the first end contacts less oil fume airflow. Therefore, if the long strip is set at a position close to the second end, or is set from the second end to a position almost in the middle, the oil fume airflow can generate an extended oil fume separation path when passing through these positions, so that as much grease and particles as possible can be separated.

[0098] Further, when the raised structure is a long strip-shaped raised structure, the height of the long strip-shaped raised structure near the first end is less than or equal to the height of the long strip-shaped raised structure near the second end. Specifically, if the height of the long strip-shaped raised structure near the first end is equal to its height near the second end, it means that the height of the long strip-shaped raised structure is uniformly set. If the height of the long strip-shaped raised structure near the first end is less than its height near the second end, it means that the height of the long strip-shaped raised structure can gradually increase from the first end to the second end, or the height of the long strip-shaped raised structure near the first end is relatively small, the height of the long strip-shaped raised structure near the middle is relatively large, and the height of the raised structure near the second end is also relatively small, but it should be ensured that the height of the raised structure near the second end should be greater than the height of the raised structure near the first end. Such a design is adopted mainly because: when the interception fan blade 1 is applied to the separation disk for oil fume interception, the number of the interception fan blades 1 is large, and a gap should be formed between two adjacent interception fan blades 1 for the oil fume airflow to pass through, so that the oil fume airflow can contact the interception fan blade and the raised structure 1a on the interception fan blade. Since the gap gradually increases from the first end to the second end, if the protrusion height of the long strip protrusion at the first end is too high, it may cause the gap between the two adjacent interception blades at the first end to be smaller, which is not conducive to the installation of the two adjacent interception blades. In addition, it can be seen from the above that when the oil fume airflow enters the gap, it first contacts the second end and the middle position. Therefore, the protrusion height of the long strip protrusion at the second end and the middle position can be slightly larger than the protrusion height at the first end, which can not only reduce the width of the gap so that the oil fume airflow will not pass through the gap all at once, but also slow down the speed of the oil fume airflow passing through these positions as much as possible, thereby improving the oil fume separation effect.

[0099] Furthermore, in order to facilitate the connection between two adjacent intercepting wind blades 1, when the protrusion structure is a long strip protrusion and the first end extends toward the second end, and when the length of the long strip protrusion is equal to the length of the intercepting wind blade 1, a transition portion 10 can be set at a position close to the first end of the long strip protrusion, and the height of the transition portion 10 can gradually increase from the first end to the second end.

[0100] When the length of the long strip protrusion is smaller than the length of the intercepting wind blade 1, a transition portion 10 can be set at a position of the intercepting wind blade close to the first end 111. Similarly, the height of the transition portion 10 gradually increases from the first end to the second end, and the transition portion 10 may be connected to the long strip protrusion or not.

[0101] By adopting the above-mentioned method of arranging the transition part 10, when the intercepting fan blade 1 is installed on the separation plate, the installation of two adjacent intercepting fan blades 1 can be made more compact due to the arrangement of the transition part 10.

[0102] It can be known that, in actual processing, the transition portion 10 can be formed by providing a wedge-shaped block at a position of the long strip protrusion close to the first end, or by providing a wedge-shaped block at a position of the intercepting blade close to the first end.

[0103] Taking the convex pillars as an example, among the multiple convex pillars, the spacing between two adjacent convex pillars near the first end may be greater than the spacing between two adjacent convex pillars near the second end, and the arrangement may be roughly as follows: the multiple convex pillars are arranged from sparse to dense from the first end to the second end, or the multiple convex pillars may be arranged sparsely from the first end to the middle, then evenly arranged in the middle, and finally densely arranged from the middle to the second end 112, etc. In other words, when multiple convex pillars are provided, there may be multiple ways of uneven arrangement, and these multiple arrangement ways may be adjusted and set according to actual conditions.

[0104] The above arrangement is adopted mainly because: when the intercepting fan blade 1 is applied to the separation plate to intercept oil smoke, the oil smoke airflow first contacts the second end and the middle position. Therefore, the arrangement of the convex columns at the second end and the middle position can be slightly denser than the arrangement at the first end, which can slow down the speed of the oil smoke airflow passing through the second end and the middle position as much as possible, thereby improving the oil smoke separation effect.

[0105] In this embodiment, the first blade portion 11 and the second blade portion 12 are of equal length, and because the cross section of the intercepting blade 1 is V-shaped, the second blade portion 12 intersects with the first blade portion 11 to form a first angle α.

[0106] Further, the first angle α may be in the range of 30° to 150°. Preferably, the first angle α may be 30°, 45°, 60°, 90°, 100°, 115°, 120°, 135°, 140° or 150°.

[0107] Since the intercepting blade 1 is applied to the separation disk to intercept and separate the oil smoke, in practical applications, the intercepting blade 1 is usually installed on the fixed disk of the separation disk. Specifically, the fixed connection method between the intercepting blade 1 and the fixed disk of the separation disk can be: welding, riveting, bolt and screw connection, snap connection, pin connection, elastic deformation connection, lock connection or plug-in, etc. Taking riveting as an example, if the intercepting blade 1 is riveted to the fixed disk, the first end 111 of the first blade part 11 and / or the second blade part 12 can be riveted to the fixed disk, or the second end 112 of the first blade part 11 and / or the second blade part 12 can be riveted to the fixed disk, and of course, the first end 111 and the second end 112 of the first blade part 11 and the second blade part 12 can also be riveted and fixed to the fixed disk at the same time.

[0108] Furthermore, in order to facilitate the installation and connection between the intercepting fan blade 1 and the separation disk, a blade root portion may be provided on the first end of the intercepting fan blade, and the blade root portion includes a flat insertion portion 13 and a clamping portion 14 extending outward from the insertion portion, and the insertion portion and the clamping portion are respectively used to be installed to the fixed disk of the separation disk, so that the intercepting fan blade 1 is fixed to the fixed disk. Specifically, the blade root portion 1c is a short strip-shaped sheet, and the length ratio of the blade root portion 1c to the length of the intercepting fan blade 1 can be 1:10 to 1:15. Preferably, the length ratio of the blade root portion 1c to the intercepting fan blade 1 can be 1:10, 1:11, 1:12, 1:13, 1:14 or 1:15, etc.

[0109] The length ratio between the blade root 1c and the intercepting blade is limited in order to avoid the situation where the length ratio between the blade root 1c and the intercepting blade is too large, resulting in insufficient connection strength of the blade root 1c to the intercepting blade, which may cause breakage at the connection between the blade root 1c and the intercepting blade during high-speed rotation.

[0110] Specifically, the blade root portion may be wedge-shaped as a whole, for example, both the inserting portion and the clamping portion may be wedge-shaped, or only the inserting portion may be wedge-shaped, while the clamping portion may not necessarily be wedge-shaped.

[0111] In this embodiment, it is preferred that the blade root is wedge-shaped as a whole.

[0112] The design that the inserting part is flat and the thickness of the inserting part is greater than the thickness of the clamping part is mainly because: when the intercepting blade 1 is installed on the fixed disk of the separation disk, in order to ensure the oil fume separation effect, the intercepting blades 1 are installed on the fixed disk in large numbers, and the intercepting blades are installed on the fixed disk in a planar radial distribution along the radial direction of the fixed disk. Therefore, in order to make the inserting parts of adjacent intercepting blades tightly connected to the fixed disk, the overall thickness of the inserting part 13 needs to be greater than the overall thickness of the clamping part 14. In addition, the above design is also conducive to enhancing the strength of the connection between the blade root 1c and the main part 1b, avoiding the connection position from being insufficiently strong and breaking during high-speed rotation.

[0113] Specifically, the inclination angle of the insertion portion can be θ, wherein 1°≤θ≤4°. For example, θ can be 1°, 1.5°, 2°, 2.5°, 3°, 3.5°, 4°, etc. The inclination angle cannot be too large. If it is too large, it will be detrimental to the fitting of the blade roots 1c of the two adjacent interception blades 1, thereby affecting the size of the gap formed by the two adjacent interception blades 1. If the inclination angle is too small, the thickness difference between the insertion portion 13 and the clamping portion 14 is not obvious. If the thickness of the insertion portion 13 and the clamping portion 14 are both large, the overall weight of the interception blade 1 may increase, and material waste may be caused. If the thickness of the insertion portion 13 and the clamping portion 14 are both small, the blade root 1c may be insufficient in strength, and may break during high-speed rotation. Therefore, the inclination angle should be roughly maintained at a value of 1°≤θ≤4°.

[0114] In this embodiment, since the intercepting blades 1 need to be installed on a fixed plate during actual use, and in order to improve the oil fume separation efficiency, the number of the intercepting blades 1 is relatively large. The insert portion has an inclined surface 13a, and taking the inclined surface 13a as an example of a side facing the V-shaped inner side of the intercepting blade 1, in order to further facilitate the fitting connection of two adjacent intercepting blades 1, a protrusion 131 may be provided on the inclined surface 13a, and the protrusion 131 is used to make the blade roots 1c of the two adjacent intercepting blades 1 have a gap smaller than the minimum value of the gap when connected, and the gap can be used to fill the adhesive (not shown), so that the blade roots 1c of the two adjacent intercepting blades 1 can be bonded together. Specifically, the protrusion 131 can be set at the center of the inclined surface 13a, and the protruding height of the protrusion 131 should be less than one tenth to one ninth of the thickness of the blade root 1c itself, so that the size of the gap formed between the blade roots 1c of the two adjacent intercepting blades 1 can be controlled.

[0115] The size of the gap is limited mainly to avoid the problem that the gap between the two adjacent intercepting blades 1 is too large due to the gap being too large, thus affecting the separation effect of the oil smoke, and at the same time, it can also reduce the use of adhesive, thereby avoiding waste. If the gap is too small, there will be too little adhesive between the blade roots 1c of the two adjacent gaps, and it will be difficult for the adhesive to play its role, resulting in the blade roots 1c of the two adjacent gaps being unable to be fastened and bonded together.

[0116] In addition, filling the gap with adhesive can not only fix the root portions 1c of the two adjacent intercepting fan blades 1, but also utilize the airtight property of the adhesive to prevent the oil smoke from being directly discharged from the root portions 1c of the two adjacent intercepting fan blades 1, so that the oil smoke can only be discharged after being gathered at the second end of the intercepting fan blade and separated, thereby further effectively improving the separation effect of the oil smoke.

[0117] In this embodiment, in order to make the connection between the blade roots 1c of two adjacent intercepting blades 1 tighter, a transition surface 132 is formed at the connection between the insertion portion 13 of the blade root 1c and the intersection. Specifically, the transition surface 132 can be formed on the inner side and / or outer side of the V-shape of the intercepting blade 1. Preferably, the transition surface 132 can be a plane, so that when the two adjacent intercepting blades 1 are connected, the fit between the two intercepting blades 1 is higher at the position of the transition surface 132, thereby avoiding the formation of a gap at the position of the transition surface 132.

[0118] Furthermore, since the intercepting blade is provided with a transition portion 10 at a position of the long strip protrusion near the first end, when the intercepting blade is mounted on the fixing plate, for two adjacent intercepting blades, the inner side of one intercepting blade is opposite to the outer side of the other intercepting blade, and the transition surface of the one intercepting blade is matched with the transition portion 10 of the other intercepting blade. Specifically, for two adjacent intercepting blades, since the transition surface is a plane, the transition portion 10 can be completely attached to or approximately attached to the transition surface, so that the two can be tightly connected.

[0119] In this embodiment, the intercepting blade is an axisymmetric structure, that is, the first blade portion and the second blade portion of the intercepting blade are symmetrical about the angular bisector of the intercepting blade.

[0120] Furthermore, when the interception blades are applied to the separation disk and mounted to the fixing plate, the angular bisectors of the interception blades overlap. The purpose of limiting the angular bisectors of the interception blades to overlap and the interception blades to be an axisymmetric structure is to ensure that when the separation disk rotates, the oil fume airflow only enters or is discharged from the gap of the separation disk, and will not be discharged directly from the bottom and / or top of the separation disk, thereby ensuring that the oil fume airflow can be intercepted and separated in the gap.

[0121] It can be known that the degree of overlap of the angular bisectors of the intercepting blades depends on the actual installation process and the processing accuracy of the intercepting blades, and often cannot be accurately overlapped, but as long as they roughly overlap, the purpose of the present invention can be achieved. That is, the direct discharge of the oil smoke-free airflow above and / or below the separation disk is achieved.

[0122] The separation disk with a raised structure provided in the first embodiment of the present invention adopts an intercepting fan blade with a V-shaped cross-section. A raised structure is arranged on the inner side of the V-shape of the intercepting fan blade and at the intersection of the first blade part and the second blade part, so that the oil smoke continuously rotates at the position where it passes through the raised structure, thereby increasing the probability of the oil smoke colliding with the raised structure, thereby increasing the separation path of the oil smoke, so that more oil droplets are separated and the separation effect is better.

[0123] Embodiment 2

[0124] See also Fig.10The second embodiment of the present invention provides an interception fan blade 1 that can extend the oil smoke separation path, which is different from the first embodiment of the present invention in that:

[0125] The protruding structure 1 a is provided not only at the intersection of the first blade portion 11 and the second blade portion 12 , but also at the first blade portion 11 or the second blade portion 12 .

[0126] It should be known that the convex structure 1a is respectively provided at the intersection of the first blade part 11 and the second blade part 12 (referred to as the intersection in this embodiment) and the position where the first blade part 11 does not intersect with the second blade part 12 (referred to as the non-intersection in this embodiment), including the following schemes:

[0127] The first type: the protruding structure 1a is provided on the intersection and the first blade part 11 respectively.

[0128] The second type: the protruding structure 1a is provided on the intersection and the second blade part 12 respectively.

[0129] The third type: the protruding structure 1a is provided on the intersection, the first blade part 11 and the second blade 12.

[0130] Similarly, if a raised structure 1a is provided at the intersection, and a raised structure 1a is also provided at the position where the second blade portion 12 does not intersect with the first blade portion 11, the setting method of the raised structure 1a can be the same as the setting method at the position where the first blade portion 11 does not intersect with the second blade portion 12, and will not be repeated here.

[0131] In addition, the specific structures of the protruding structure 1a, the first blade part 11, and the second blade part 12 in the second embodiment can be found in the description of the first embodiment, and will not be repeated here.

[0132] The intercepting fan blade with a protruding structure disclosed in the second embodiment of the present invention can further increase the collision probability between the oil smoke and the intercepting fan blade by respectively setting the protruding structures at the intersection and the non-intersection, thereby further extending the path of the oil smoke passing through the intercepting fan blade, which is beneficial to improving the separation rate of the oil smoke.

[0133] Embodiment 3

[0134] Combination Figure 1 , Figure 2 , Figures 11 to 13 As shown, the third embodiment of the present invention provides an interception blade 1 that can extend the oil smoke separation path. The difference between the third embodiment of the present invention and the second embodiment of the present invention is that:

[0135] The third embodiment provides a specific arrangement of the protruding structure 1 a on the first blade portion 11 or on the second blade portion 12 .

[0136] On the basis of the convex structure 1a being provided at the intersection of the first blade part 11 and the second blade part 12, a convex structure 1a is further provided at the inner non-intersecting part of the first blade part 11 or the inner non-intersecting part of the second blade part 12. Specifically, since the first blade part 11 and the second blade part 12 have the same structure, the following description of the third embodiment takes the first blade part 11 as an example, and the case where the convex structure 1a is provided on the second blade part 12 is the same as that of the first blade part 11, so it will not be repeated.

[0137] The non-intersecting portion on the inner side of the first blade portion 11 refers to a position where the inner side of the first blade portion 11 and the second blade portion 12 do not intersect.

[0138] In this embodiment, a plurality of protruding structures 1a are provided at non-intersecting portions of the inner side of the first blade portion 11, and the plurality of protruding structures 1a are completely distributed at the inner side of the first blade portion 11, or the plurality of protruding structures 1a are provided at local positions of the inner side of the first blade portion 11. Preferably, the protruding structures 1a are completely distributed at non-intersecting portions of the inner side of the first blade portion 11.

[0139] See also Figure 4 and Fig.11 , Fig.11 An embodiment of the present invention is to provide a protruding structure 1a at a position close to the second end of the intersection and the inner non-intersection of the first blade 11 .

[0140] Understandably, Fig.11 The raised structure 1a of the first blade part 11 is not arranged on the same horizontal line as the raised structure 1a at the intersection. If the raised structure 1a on the inner side of the first blade part 11 and the raised structure 1a at the intersection are arranged on the same horizontal line, then the ventilation volume on the horizontal line is almost zero because the space in the gap is occupied. Therefore, it is preferred to stagger the raised structure 1a on the inner side of the first blade part 11 and the raised structure 1a at the intersection.

[0141] It can be known that, when the protruding structure 1a and the protruding structure 1a are not set at the first end 111 of the intersection and the first end 111 of the first blade part 11, the first end 111 of the intersection of two adjacent intercepting blades 20 and the first end 111 of the first blade part 11 of the two adjacent intercepting blades 20 are both close to each other, and the distance between the first end 111 of the intersection of two adjacent intercepting blades 20 and the first end 111 of the first blade part 11 of the two adjacent intercepting blades 20 is already very small. If the protruding structure 1a and the protruding structure 1a are set again, ventilation cannot be achieved between the first end 111 of the intersection of two adjacent intercepting blades 20 and the first end 111 of the first blade part 11 of the two adjacent intercepting blades 20.

[0142] See also Fig.12 In the present embodiment, taking the example of setting a protruding structure 1a on the intersection and setting a protruding structure 1a on the inner side of the first blade part 11, a plurality of protruding structures 1a are evenly arranged on the intersection, a plurality of protruding structures 1a are evenly arranged on the first blade part 11, or the protruding structures 1a and the protruding structures 1a are arranged from sparse to dense or from dense to sparse at the intersection and on the first blade part 11 along the length extension direction of the first blade part 11.

[0143] As a first optional implementation (such as Fig.12 As shown in part a of the figure, the raised structure 1a may be spaced apart raised columns which are evenly distributed at the intersection and on the first blade portion 11.

[0144] As a second optional implementation (such as Fig.12 As shown in part b in the figure, the raised structure 1a may be spaced apart raised columns, which are arranged from sparse to dense from the first end 111 to the second end 112 at the intersection, and the raised columns are also arranged from sparse to dense from the first end 111 to the second end 112 of the intercepting wind blade 20.

[0145] As a third optional implementation (such as Fig.12 As shown in part c in the figure, the raised structure 1a may be spaced apart raised columns, which are not only densely arranged to sparsely arranged from the first end 111 to the second end 112 at the intersection, but also densely arranged to sparsely arranged from the first end 111 to the second end 112 of the intercepting wind blade 20.

[0146] See also Fig.13 , taking the case where a single protruding structure 1a and a protruding structure 1a are provided at the intersection and the first blade portion 11 as an example,

[0147] As a first optional implementation, (such as Fig.13 As shown in parts a and b in the figure, the raised structure 1a may be an extended raised column which is evenly distributed at the intersection with the first blade portion 11. Part a shows a situation where the raised structure 1a on the first blade portion 11 is the same as the raised structure 1a at the intersection, and part b shows a situation where the raised structure 1a on the first blade portion 11 is different from the raised structure 1a at the intersection.

[0148] As a second optional implementation (such as Fig.13 As shown in part c in the figure, the raised structure 1a may be an extended raised column, which may be sparsely or densely arranged from the first end 111 to the second end 112 at the intersection, or the raised column may be sparsely or densely arranged from the first end 111 to the second end 112 of the intercepting wind blade 20.

[0149] As a third optional implementation (such as Fig.13 As shown in part d in the figure, the raised structure 1a may be an extended raised column, which may be arranged from dense to sparse from the first end 111 to the second end 112 at the intersection, and the raised column may also be arranged from dense to sparse from the first end 111 to the second end 112 of the intercepting wind blade 20.

[0150] It should be noted that the raised structure 1a on the first blade part 11 should be set on the side as far away from the intersection as possible, otherwise the raised structure 1a of the first blade part 11 near the second end 112 will contact each other, making the gap formed between the intersection and the first blade part 11 too small, reducing the ventilation volume, thereby reducing the separated air volume and affecting the separation efficiency.

[0151] Similarly, the manner of arranging the protruding structures 1a and 1a at the intersection and the inner side of the second blade portion 12 is the same as the manner of arranging the protruding structures 1a and 1a at the intersection and the inner side of the first blade portion 11, and will not be repeated here.

[0152] Embodiment 3 of the present invention provides an intercepting fan blade that can extend the oil fume separation path. By arranging a protruding structure on the intersection of the intercepting fan blade and a protruding structure on the first blade part or the second blade part, and making the protruding structure on the first blade part or the second blade part be arranged at a certain distance from the protruding structure arranged at the intersection, it is possible to extend the separation time of the oil fume passing through the intersection and the first blade part or the second blade part while leaving enough space for the oil fume to pass through the separation plate, thereby effectively improving the separation rate.

[0153] Embodiment 4

[0154] Combination Figure 1 , Figure 2 , Fig.14 , Fig.15 As shown, the fourth embodiment of the present invention provides an interception blade that can extend the oil smoke separation path. The difference between the fourth embodiment of the present invention and the third embodiment of the present invention is that:

[0155] The protruding structure 1 a is disposed at the intersection, and the protruding structure 1 a is disposed on the first blade portion 11 and the second blade portion 12 respectively.

[0156] Specifically, the convex structure 1 a provided on the intersection may be the same as or different from the convex structure 1 a provided on the inner side of the first blade portion 11 and the inner side of the second blade portion 12 .

[0157] See also Fig.14As an optional implementation, the protrusion structure 1a is symmetrically arranged on the first blade part 11 and the second blade part 12, so that the separation disk rotates smoothly and ensures the stability of the separation disk.

[0158] See also Figure 4 and Fig.15 , Fig.15 The method in which the number of the raised structures 1a arranged on the inner side of the first blade part 11 is greater than the number of the raised structures 1a arranged on the inner side of the second blade part 12 is shown in the figure. The number of the raised structures 1a arranged on the inner side of the first blade part 11 is greater than the number of the raised structures 1a arranged on the inner side of the second blade part 12 is mainly due to the following considerations: Taking the raised structures 1a arranged at the intersection, the raised structures 1a on the inner side of the first blade part 11 and the inner side of the second blade part 12 as conical raised structures as an example, when the separation disk is applied to the dynamic interceptor for oil fume separation, the oil fume enters the separation disk from below The gap between two adjacent intercepting blades 1 is a two-fold gap that first moves to the right and then to the left. During the process of the intercepting blade rotating to the right, the movement direction of the oil smoke is to the upper right, so the gas easily enters the lower part of the gap, and the actual movement direction of the gas in the upper part of the gap is to the upper left, but the expected movement direction of the gas is to the upper right, so the gas has a process of deceleration in the upper part of the gap. Therefore, more protruding structures 1a are set in the upper part where the speed of gas passing through the gap is slower, so more solid-liquid mixtures in the gas can be intercepted and stuck. Therefore, this setting method can effectively improve the separation rate.

[0159] In addition, when a raised structure 1a is provided on the intersection and a raised structure 1a is provided on the inner side of the first blade portion 11 and the inner side of the second blade portion 12 at the same time, the raised structure 1a on the first blade portion 11 and the second blade portion 12 should be provided on the side as far away from the intersection as possible, so that sufficient space can be reserved at the intersection, the first blade portion, and between the intersection and the second blade portion for oil smoke to pass through.

[0160] Embodiment 4 of the present invention provides an intercepting fan blade that can extend the oil fume separation path, by setting a protruding structure at the intersection of the intercepting fan blade and setting a protruding structure on the first blade part and the second blade part, wherein the protruding structure on the first blade part and the second blade part are set at a certain distance from the protruding structure set at the intersection, so that the oil fume not only increases the separation time, but also leaves enough space for the oil fume to pass through the separation plate, thereby effectively improving the separation rate.

[0161] Embodiment 5

[0162] Please also refer to 4 and Figures 16 to 18Embodiment 7 of the present invention discloses a separation disc 200, which is used to be installed on a rotating shaft to intercept and separate grease and / or solid mixtures in oil smoke. The separation disc 200 includes a fixed disc 2 and a plurality of long strip-shaped interception blades 1, and the plurality of interception blades 1 are radially distributed with the center of the fixed disc 2 as the center, and one end of the plurality of interception blades 1 is fixedly connected to the fixed disc 2, and a gap 1d for oil smoke to pass through is formed between two adjacent interception blades 1, and all or part of the interception blades 1 are provided with a protruding structure 1a for extending the separation path when the oil smoke passes through the gap 1d.

[0163] It should be known that when the intercepting fan blades 1 are installed on the fixed plate of the separation plate, in order to improve the oil fume separation efficiency, the number of intercepting fan blades 1 should be multiple, specifically 50 to 150 pieces, and a gap should be formed between two adjacent intercepting fan blades 1 so that the oil fume airflow can pass into the gap and contact the intercepting fan blades 1, thereby achieving the purpose of oil fume separation.

[0164] When the interception blades 1 are installed on the separation disk and the separation disk rotates at a certain speed, the oil fume airflow enters the separation disk from one side of the separation disk. When the oil fume airflow passes through the gap between adjacent interception blades 1, the grease, particles, etc. in the oil fume will collide with the side of the interception blades 1 on both sides of the gap between the interception blades 1 and be adsorbed on the side of the interception blades 1, and thrown out along the radial direction of the interception blades 1 to achieve the oil fume separation effect. In order to provide the power for the oil fume airflow to pass through the separation disk, a negative pressure fan can be provided to provide the power for sucking the oil fume, or the power for sucking the oil fume can be generated by the separation disk itself.

[0165] In this patent, due to the presence of a raised structure on the intercepting blade 1, when the oil fume airflow passes through the gap of the intercepting blade 1 of the separation disk, the oil fume airflow will pass through a longer distance compared to the blade without a raised structure, increasing the probability of contact between the oil fume, grease, and particles in the oil fume and the intercepting blade and increasing the path of the oil fume airflow through the separation disk to a certain extent, reducing the probability of the oil fume, grease, and particles in the oil fume passing directly through the gap of the intercepting blade 1 without being intercepted, thereby improving the intercepting blade 1's ability to collide and adsorb the oil and particles in the oil fume, and maximizing the oil fume separation effect. The raised structure on the intercepting blade 1 can adopt one or more minimum raised structure units, and the raised structure can be set at any position on the intercepting blade and adopt any structure, such as being set on the side, top or bottom of the intercepting blade, and any possible structure that can increase the probability of oil fume colliding with the intercepting blade when the oil fume airflow passes through the gap of the intercepting blade to extend the separation path of the oil fume belongs to the protection scope of this patent.

[0166] In the prior art, the blades of fluid equipment are as flat as possible so that working media such as gas and liquid can pass through the blades in the shortest time instead of extending the time it takes to pass through the blades. The blades of some fluid machinery even have strict restrictions on the roughness of their surfaces to ensure that gas, liquid, etc. can pass through the blades quickly. Therefore, providing a raised structure on the surface of the blade to increase the probability of the oil smoke airflow colliding with the intercepting blade and extending the path through the blade is not only not common knowledge in the art, but even a technical means that violates common knowledge in the art.

[0167] It should be known that the raised structure 1a of the present invention refers to: a structure arranged on the intercepting fan blade 1, which can increase the path of the oil smoke passing through the intercepting fan blade 1 when the oil smoke passes through the intercepting fan blade 1, for example, it can be a raised strip, a raised point, a raised column or other protrusions arranged on the intercepting fan blade 1.

[0168] like Figure 1 , Figure 2 As shown, in the present embodiment, the cross section of the intercepting blade 1 has one or more bends, one side of the cross section is the inner side of the intercepting blade 1, and the other side of the cross section is the outer side of the intercepting blade 1, and the inner side of the cross section may be provided with the convex structure. Specifically, since the intercepting blade is in the shape of an elongated strip, the cross section is a cross section along a length direction perpendicular to the intercepting blade 1, and the cross section may be any shape with bends, such as a V-shape, a W-shape, a polygon, or a Z-shape. For example, when the cross section is in the shape of a V-shape, it has a single bend; when the cross section is in the shape of a W-shape, it has three bends; when the cross section is in the shape of a polygon, such as a parallelogram, a rhombus, a square, a rectangle, a pentagon, a hexagon, an octagon, etc., it has at least four bends; when the cross section is in the shape of a Z-shape, it has two bends.

[0169] Generally, since a bend usually forms an angle, the inner side of the bend is usually one side of the angle space forming the angle, and the outer side of the bend is the side opposite to the inner side.

[0170] It can be known that when the protruding structure 1a is provided on the intercepting blade, the protruding structure can be provided on the inner side of the cross section of the intercepting blade 1 .

[0171] In this embodiment, the intercepting wind blade 1 includes a first blade portion 11 and a second blade portion 12 which are flat and long strips. The first blade portion includes a first side surface 110 and a second side surface opposite to the first side surface 110. The second blade portion includes a third side surface 120 and a fourth side surface opposite to the third side surface 120. The first side surface 110 of the first blade portion and the third side surface 120 of the second blade portion intersect, so that the cross-section of the intercepting wind blade 1 is a V-shaped cross-section. The concave side of the V-shaped cross-section is the inner side of the intercepting wind blade, and the other side corresponding to the concave side of the V-shaped cross-section is the outer side of the intercepting wind blade. Specifically, the first side surface 110 of the first blade part and the third side surface 120 of the second blade part substantially overlap, thereby forming the V-shaped cross section, while the second side surface of the first blade part is away from the first side surface 110, and the third side surface 120 of the second blade part is away from the fourth side surface. The blade surface of the first blade part is formed between the first side surface 110 and the second side surface, and the blade surface of the second blade part is formed between the third side surface 120 and the fourth side surface. As can be seen from the above, the convex structure 1a can be set inside the V-shaped cross section.

[0172] From the above, it can be seen that the inner side of the V-shape refers to the side of the V-shape forming an angle space, while the outer side of the V-shape is the side opposite to the inner side (such as Figure 2 shown).

[0173] Further, the protruding structure 1a is provided at the intersection of the first blade part 11 and the second blade part 12 and / or at the non-intersecting part of the first blade part 11 and / or the second blade part 12. Specifically, the first blade part and the second blade part are both long flat sheet-like parts.

[0174] Taking the case where the protruding structure 1a is disposed at the intersection of the first blade portion 11 and the second blade portion 12 as an example, the position of the protruding structure 1a on the intercepting blade 1 can be: the protruding structure 1a is disposed at the intersection of the first blade portion 11 and the second blade portion 12, and the protruding structure 1a is located on the inner side of the V-shape (such as Figure 3 shown);

[0175] The first embodiment of the present invention is preferably described by taking the case where the protruding structure 1 a is located at the inner side of the V-shape and is provided at the intersection of the first blade portion 11 and the second blade portion 12 as an example.

[0176] Specifically, when the intercepting fan blade 1 is installed on the fixed plate of the separation plate, the second blade part 12 is located above the first blade part 11 along the air intake direction of the oil smoke, that is, when the oil smoke passes through the intercepting fan blade 1, it first contacts the first blade part 11. Since the protruding structure 1a is not provided on other non-intersecting positions of the first blade part 11 (i.e., the surface of the first blade part 11), the oil smoke will pass through quickly. When the oil smoke continues to move upward along the surface of the first blade part 11 to the intersection position, the oil smoke is affected by the protruding structure 1a provided on the intersection, and the oil smoke continuously rotates at the intersection of the first blade part 11 and the second blade part 12, thereby forming a self-rotating flow field, where a large number of oil droplets gather until the oil droplets gather to a certain weight, and then the oil droplets are separated from the flow field and thrown out.

[0177] It can be seen that the design of arranging the raised structure 1a at the intersection of the first blade part 11 and the second blade part 12 and being located on the inner side of the V-shape can effectively extend the path of the oil smoke passing through the intersection, so that as many oil droplets as possible can be separated, preventing the oil smoke from quickly passing through the first blade part 11 and the second blade part 12 when the oil droplets are not separated, thereby effectively ensuring the oil smoke separation effect.

[0178] It should be known that the protruding structure 1a can be integrally formed at the intersection of the first blade portion 11 and the second blade portion 12, thereby simplifying the processing steps of the intercepting blade 1 and improving the processing efficiency. At the same time, the integral molding method can also avoid the situation where the protruding structure 1a adopts a split design and there may be gaps or additional parts, which may cause oil droplets to accumulate in the gaps or additional parts, which is not conducive to the cleaning of the intercepting blade 1.

[0179] Combination Figures 4 to 8 As shown, in this embodiment, since the intercepting blade 1 is a long strip component, the two ends of the intercepting blade 1 are respectively the first end 111 and the second end 112, and the first end 111 and the second end 112 are respectively the two ends in the length direction of the intercepting blade 1, and the protruding structure 1a can be a long strip protrusion, and the protruding structure 1a extends from the first end 111 to the second end 112, or the length direction of the protruding structure 1a extends along the length direction of the intercepting blade 1, and the length of the protruding structure 1a is less than the length of the intercepting blade 1. Specifically, when the intercepting blade is applied to a separation disk and mounted to a fixing disk of the separation disk, the first end of the intercepting blade is preferably an end close to the center of the separation disk, and the second end of the intercepting blade is an end relatively far from the center of the separation disk.

[0180] As another optional embodiment, the raised structure is also a long strip, but the length of the raised structure 1a is less than the length of the intercepting blade 1. For example, the raised strip is only set at a position close to the first end of the intercepting blade 1, or is set from the first end to a position almost in the middle, or is only set at a position close to the second end, or is set from the second end to a position almost in the middle, etc. This method is mainly adopted because: when the intercepting blade 1 is used in the separation disk for oil fume interception, the number of intercepting blades 1 is large. When multiple intercepting blades are installed, the second end 112 of the intercepting blade is usually the first to contact the oil fume airflow, while the first end contacts less oil fume airflow. Therefore, if the long strip is set at a position close to the second end, or is set from the second end to a position almost in the middle, the oil fume separation path can be extended when the oil fume airflow passes through these positions, so that as much grease and particles as possible can be separated.

[0181] Further, when the raised structure is a long strip-shaped raised structure, the height of the long strip-shaped raised structure near the first end is less than or equal to the height of the long strip-shaped raised structure near the second end. Specifically, if the height of the long strip-shaped raised structure near the first end is equal to its height near the second end, it means that the height of the long strip-shaped raised structure is uniformly set. If the height of the long strip-shaped raised structure near the first end is less than its height near the second end, it means that the height of the long strip-shaped raised structure can gradually increase from the first end to the second end, or the height of the long strip-shaped raised structure near the first end is relatively small, the height of the long strip-shaped raised structure near the middle is relatively large, and the height of the raised structure near the second end is also relatively small, but it should be ensured that the height of the raised structure near the second end should be greater than the height of the raised structure near the first end. Such a design is adopted mainly because: when the interception fan blade 1 is applied to the separation disk for oil fume interception, the number of the interception fan blades 1 is large, and a gap should be formed between two adjacent interception fan blades 1 for the oil fume airflow to pass through, so that the oil fume airflow can contact the interception fan blade and the raised structure 1a on the interception fan blade. Since the gap gradually increases from the first end to the second end, if the protrusion height of the long strip protrusion at the first end is too high, it may cause the gap between the two adjacent interception blades at the first end to be smaller, which is not conducive to the installation of the two adjacent interception blades. In addition, it can be seen from the above that when the oil fume airflow enters the gap, it first contacts the second end and the middle position. Therefore, the protrusion height of the long strip protrusion at the second end and the middle position can be slightly larger than the protrusion height at the first end, which can not only reduce the width of the gap so that the oil fume airflow will not pass through the gap all at once, but also slow down the speed of the oil fume airflow passing through these positions as much as possible, thereby improving the oil fume separation effect.

[0182] Furthermore, in order to facilitate the connection between two adjacent intercepting wind blades 1, when the protrusion structure is a long strip protrusion and the first end extends toward the second end, and when the length of the long strip protrusion is equal to the length of the intercepting wind blade 1, a transition portion 10 can be set at a position close to the first end of the long strip protrusion, and the height of the transition portion 10 can gradually increase from the first end to the second end.

[0183] When the length of the long strip protrusion is smaller than the length of the intercepting wind blade 1, a transition portion 10 can be set at a position of the intercepting wind blade close to the first end 111. Similarly, the height of the transition portion 10 gradually increases from the first end to the second end, and the transition portion 10 may be connected to the long strip protrusion or not.

[0184] By adopting the above-mentioned method of arranging the transition part 10, when the intercepting fan blade 1 is installed on the separation plate, the installation of two adjacent intercepting fan blades 1 can be made more compact due to the arrangement of the transition part 10.

[0185] It can be known that, in actual processing, the transition portion 10 can be formed by providing a wedge-shaped block at a position of the long strip protrusion close to the first end, or by providing a wedge-shaped block at a position of the intercepting blade close to the first end.

[0186] Taking the convex pillars as an example, among the multiple convex pillars, the spacing between two adjacent convex pillars near the first end may be greater than the spacing between two adjacent convex pillars near the second end, and the arrangement may be roughly as follows: the multiple convex pillars are arranged from sparse to dense from the first end to the second end, or the multiple convex pillars may be arranged sparsely from the first end to the middle, then evenly arranged in the middle, and finally densely arranged from the middle to the second end 112, etc. In other words, when multiple convex pillars are provided, there may be multiple ways of uneven arrangement, and these multiple arrangement ways may be adjusted and set according to actual conditions.

[0187] The above arrangement is adopted mainly because: when the intercepting fan blade 1 is applied to the separation plate to intercept oil smoke, the oil smoke airflow first contacts the second end and the middle position. Therefore, the arrangement of the convex columns at the second end and the middle position can be slightly denser than the arrangement at the first end, which can slow down the speed of the oil smoke airflow passing through the second end and the middle position as much as possible, thereby improving the oil smoke separation effect.

[0188] In this embodiment, the first blade portion 11 and the second blade portion 12 are of equal length, and because the cross section of the intercepting blade 1 is V-shaped, the second blade portion 12 intersects with the first blade portion 11 to form a first angle α.

[0189] Further, the first angle α may be in the range of 30° to 150°. Preferably, the first angle α may be 30°, 45°, 60°, 90°, 100°, 115°, 120°, 135°, 140° or 150°.

[0190] Since the intercepting blade 1 is applied to the separation disk to intercept and separate the oil smoke, in practical applications, the intercepting blade 1 is usually installed on the fixed disk of the separation disk. Specifically, the fixed connection method between the intercepting blade 1 and the fixed disk of the separation disk can be: welding, riveting, bolt and screw connection, snap connection, pin connection, elastic deformation connection, lock connection or plug-in, etc. Taking riveting as an example, if the intercepting blade 1 is riveted to the fixed disk, the first end 111 of the first blade part 11 and / or the second blade part 12 can be riveted to the fixed disk, or the second end 112 of the first blade part 11 and / or the second blade part 12 can be riveted to the fixed disk, and of course, the first end 111 and the second end 112 of the first blade part 11 and the second blade part 12 can also be riveted and fixed to the fixed disk at the same time.

[0191] Furthermore, in order to facilitate the installation and connection between the intercepting fan blade 1 and the separation disk, a blade root portion may be provided on the first end of the intercepting fan blade, and the blade root portion includes a flat insertion portion 13 and a clamping portion 14 extending outward from the insertion portion, and the insertion portion and the clamping portion are respectively used to be installed to the fixed disk of the separation disk, so that the intercepting fan blade 1 is fixed to the fixed disk. Specifically, the blade root portion 1c is a short strip-shaped sheet, and the length ratio of the blade root portion 1c to the length of the intercepting fan blade 1 can be 1:10 to 1:15. Preferably, the length ratio of the blade root portion 1c to the intercepting fan blade 1 can be 1:10, 1:11, 1:12, 1:13, 1:14 or 1:15, etc.

[0192] The length ratio between the blade root 1c and the intercepting blade is limited in order to avoid the situation where the length ratio between the blade root 1c and the intercepting blade is too large, resulting in insufficient connection strength of the blade root 1c to the intercepting blade, which may cause breakage at the connection between the blade root 1c and the intercepting blade during high-speed rotation.

[0193] Specifically, the blade root portion may be wedge-shaped as a whole, for example, both the inserting portion and the clamping portion may be wedge-shaped, or only the inserting portion may be wedge-shaped, while the clamping portion may not necessarily be wedge-shaped.

[0194] In this embodiment, it is preferred that the blade root is wedge-shaped as a whole.

[0195] The design that the inserting part is flat and the thickness of the inserting part is greater than the thickness of the clamping part is mainly because: when the intercepting blade 1 is installed on the fixed disk of the separation disk, in order to ensure the oil fume separation effect, the intercepting blades 1 are installed on the fixed disk in large numbers, and the intercepting blades are installed on the fixed disk in a planar radial distribution along the radial direction of the fixed disk. Therefore, in order to make the inserting parts of adjacent intercepting blades tightly connected to the fixed disk, the overall thickness of the inserting part 13 needs to be greater than the overall thickness of the clamping part 14. In addition, the above design is also conducive to enhancing the strength of the connection between the blade root 1c and the main part 1b, avoiding the connection position from being insufficiently strong and breaking during high-speed rotation.

[0196] Specifically, the inclination angle of the insertion portion can be θ, wherein 1°≤θ≤4°. For example, θ can be 1°, 1.5°, 2°, 2.5°, 3°, 3.5°, 4°, etc. The inclination angle cannot be too large. If it is too large, it will be detrimental to the fitting of the blade roots 1c of the two adjacent interception blades 1, thereby affecting the size of the gap formed by the two adjacent interception blades 1. If the inclination angle is too small, the thickness difference between the insertion portion 13 and the clamping portion 14 is not obvious. If the thickness of the insertion portion 13 and the clamping portion 14 are both large, the overall weight of the interception blade 1 may increase, and material waste may be caused. If the thickness of the insertion portion 13 and the clamping portion 14 are both small, the blade root 1c may be insufficient in strength, and may break during high-speed rotation. Therefore, the inclination angle should be roughly maintained at a value of 1°≤θ≤4°.

[0197] In this embodiment, since the intercepting blades 1 need to be installed on a fixed plate during actual use, and in order to improve the oil fume separation efficiency, the number of the intercepting blades 1 is relatively large. The insert portion has an inclined surface 13a, and taking the inclined surface 13a as an example of a side facing the V-shaped inner side of the intercepting blade 1, in order to further facilitate the fitting connection of two adjacent intercepting blades 1, a protrusion 131 may be provided on the inclined surface 13a, and the protrusion 131 is used to make the blade roots 1c of the two adjacent intercepting blades 1 have a gap smaller than the minimum value of the gap when connected, and the gap can be used to fill the adhesive (not shown), so that the blade roots 1c of the two adjacent intercepting blades 1 can be bonded together. Specifically, the protrusion 131 can be set at the center of the inclined surface 13a, and the protruding height of the protrusion 131 should be less than one tenth to one ninth of the thickness of the blade root 1c itself, so that the size of the gap formed between the blade roots 1c of the two adjacent intercepting blades 1 can be controlled.

[0198] The size of the gap is limited mainly to avoid the problem that the gap between the two adjacent intercepting blades 1 is too large due to the gap being too large, thus affecting the separation effect of the oil smoke, and at the same time, it can also reduce the use of adhesive, thereby avoiding waste. If the gap is too small, there will be too little adhesive between the blade roots 1c of the two adjacent gaps, and it will be difficult for the adhesive to play its role, resulting in the blade roots 1c of the two adjacent gaps being unable to be fastened and bonded together.

[0199] In addition, filling the gap with adhesive can not only fix the root portions 1c of the two adjacent intercepting fan blades 1, but also utilize the airtight property of the adhesive to prevent the oil smoke from being directly discharged from the root portions 1c of the two adjacent intercepting fan blades 1, so that the oil smoke can only be discharged after being gathered at the second end of the intercepting fan blade and separated, thereby further effectively improving the separation effect of the oil smoke.

[0200] In this embodiment, in order to make the connection between the blade roots 1c of two adjacent intercepting blades 1 tighter, a transition surface 132 is formed at the connection between the insertion portion 13 of the blade root 1c and the intersection. Specifically, the transition surface 132 can be formed on the inner side and / or outer side of the V-shape of the intercepting blade 1. Preferably, the transition surface 132 can be a plane, so that when the two adjacent intercepting blades 1 are connected, the fit between the two intercepting blades 1 is higher at the position of the transition surface 132, thereby avoiding the formation of a gap at the position of the transition surface 132.

[0201] Furthermore, since the intercepting blade is provided with a transition portion 10 at a position of the long strip protrusion near the first end, when the intercepting blade is mounted on the fixing plate, for two adjacent intercepting blades, the inner side of one intercepting blade is opposite to the outer side of the other intercepting blade, and the transition surface of the one intercepting blade is matched with the transition portion 10 of the other intercepting blade. Specifically, for two adjacent intercepting blades, since the transition surface is a plane, the transition portion 10 can be completely attached to or approximately attached to the transition surface, so that the two can be tightly connected.

[0202] Combination Figure 4 , Fig.16 , Fig.17As shown, in this embodiment, when the outer diameter of the separation disc 200 is known to be certain, the outer diameter of the separation disc 200 for general household or commercial use is usually not very large, so as to avoid occupying more space and also avoid the overall volume of the separation disc 200 being larger. In addition, the outer diameter of the separation disc 200 affects the size of the gap 1d between two adjacent intercepting blades 1. Therefore, in order to facilitate the description of the relationship between the long strip protrusion or the convex column and the gap 1d of the present invention, the present invention takes the radius of the separation disc 200 as 300 to 500 mm as an example for description. In order to avoid the situation that the outer diameter of the separation disc 200 itself is not large, but the height of the long strip protrusion is too high, resulting in the gap 1d formed between the two adjacent intercepting blades 1 being too small, resulting in the oil smoke being subjected to too much resistance and unable to be thrown out of the gap 1d, the height of the long strip protrusion or the convex column should be less than or equal to one fifth of the maximum value of the gap 1d. This is because the gap 1d between two adjacent intercepting blades 1 gradually increases from approaching the fixed disk 2 to moving away from the fixed disk 2, that is, the gap 1d reaches a minimum value at the end position of the first end 111 of the intercepting blade 1, and reaches a maximum value at the end position of the second end 112 of the intercepting blade 1. As can be seen from the above, regardless of whether the height of the long strip protrusion or the protrusion is uniformly set from the first end 111 to the second end 112, or the height of the long strip protrusion or the protrusion can gradually increase from low to high from the first end 111 to the second end 112, the height of the long strip protrusion or the protrusion should be less than or equal to one-fifth of the maximum value of the gap 1d. As long as the height of the long strip protrusion or the protrusion is less than one-fifth of the maximum value of the gap 1d, it can be ensured that the long strip protrusion or the protrusion will not occupy too much space in the gap 1d, so that the amount of oil smoke passing through per unit time will not be affected. The height of the long strip protrusion or protrusion is H1, and the maximum gap 1d is Lmax, then 0

[0203] The maximum gap 1dL max refers to the distance between two adjacent intercepting blades 1 at the ends farthest from the fixed disk 2 , and the radius of the separation disk 200 refers to the distance from the end of the intercepting blade 1 to the center of the fixed disk 2 .

[0204] The following is a brief description of the effect of the height of the long strip protrusions or protrusions on the oil fume separation rate, as shown in Table 1:

[0205]

[0206] Table 1

[0207] ​Table 1 shows that the separation blade 20 has different oil fume separation rates when no long strip protrusions or protrusions are provided and when long strip protrusions or protrusions of different heights are provided. It can be seen from Table 1 that when the minimum and maximum values ​​of the gap 1d remain constant, as the height H1 of the long strip protrusions or protrusions increases, the oil fume separation rate δ increases. However, when the height H1 of the long strip protrusions or protrusions increases to a certain height, when the outer diameter of the separation disc 200 remains unchanged, the gap 1d will become smaller due to the provision of the long strip protrusions or protrusions, so that less oil fume will enter the gap 1d per unit time, thereby reducing the oil fume separation efficiency. Considering the oil fume separation rate and the oil fume separation efficiency, the range of the height of the long strip protrusions or protrusions should satisfy the following: 0

[0208] In this embodiment, the outer boundary of the cross section of the protruding structure along its length direction may be an arc, a wave, a broken line or a combination thereof. Specifically, if the protruding structure is a protrusion or a convex column, the outer boundary of the cross section of the protruding structure is a convex and outward boundary. Specifically, the outer boundary of the cross section of the protruding structure may be an arc, that is, the protruding structure may be a cylinder, an elliptical column or a sphere; if the cross section of the protruding structure is a broken line, such as a two-fold line, a three-fold line or a four-fold line, etc., the protruding structure may be a triangular pyramid, a quadrangular prism, a cuboid, etc.

[0209] In addition, the outer boundary of the cross section of the protruding structure may be a combination of an arc shape and a wave shape, or a combination of an arc shape and a broken line shape, or a combination of a wave shape and a broken line shape, and so on.

[0210] In addition, when the protruding structure is disposed at the intersection of the first blade portion and the second blade portion, the center of the protruding structure is located on the bisector of the first angle α formed at the intersection.

[0211] The following is a brief description of the oil fume separation process when the protruding structure 1a is arranged at the intersection 24:

[0212] When the intercepting fan blade 1 rotates at a high speed, a gap 1d is formed between two adjacent intercepting fan blades 1. According to the Venturi effect, when the oil fume enters the gap 1d, the flow path becomes narrower and the flow velocity increases. According to Bernoulli's principle, the flow velocity of the oil fume accelerates after entering the gap 1d, and the pressure decreases and is much smaller than the pressure of the oil fume before entering the gap 1d. Therefore, negative pressure areas are formed on the upper and lower surfaces of the entire separation plate 200, thereby forming an effective suction force, which continuously and quickly draws the oil fume into the gap 1d for separation.

[0213] ​After the oil smoke enters the gap 1d, some solid mixtures are thrown out along the end of the intercepting fan blade 1 at a high tangential speed due to the centrifugal force; and a part of the oil mist continuously collides with the first blade part 11 and the second blade part 12 in the gap 1d and gathers into oil droplets, and is then thrown out at a high tangential speed under the action of centrifugal force, and another part of the oil mist is affected by the raised structure 1a provided at the intersection during the process of rising along the first blade part 11, and generates rotation at the raised structure 1a, and the oil mist gathers into oil droplets during the rotation, so that the oil droplets in the oil smoke are slowly separated, and when the oil droplets accumulate more and more and accumulate to a certain weight, the oil droplets fall due to gravity, and are then thrown out by the high-speed rotating intercepting fan blade 1, and the smoke after the oil droplet separation is directly discharged from the gap 1d.

[0214] It can be seen from this that by setting a raised structure 1a at the intersection, as much oil smoke as possible can be allowed to enter the gap 1d along the first blade part 11, and as much oil smoke as possible can be gathered at the intersection, thereby extending the time the oil smoke stays in the gap 1d and improving the oil smoke separation effect.

[0215] In this embodiment, the intercepting blade is an axisymmetric structure, that is, the first blade portion and the second blade portion of the intercepting blade are symmetrical about the angular bisector of the intercepting blade.

[0216] Furthermore, when the interception blades are applied to the separation disk and mounted to the fixing plate, the angular bisectors of the interception blades overlap. The purpose of limiting the angular bisectors of the interception blades to overlap and the interception blades to be an axisymmetric structure is to ensure that when the separation disk rotates, the oil fume airflow only enters or is discharged from the gap of the separation disk, and will not be discharged directly from the bottom and / or top of the separation disk, thereby ensuring that the oil fume airflow can be intercepted and separated in the gap.

[0217] It can be known that the degree of overlap of the angular bisectors of the intercepting blades depends on the actual installation process and the processing accuracy of the intercepting blades, and often cannot be accurately overlapped, but as long as they roughly overlap, the purpose of the present invention can be achieved. That is, the direct discharge of the oil smoke-free airflow above and / or below the separation disk is achieved.

[0218] In this embodiment, the fixed disk is provided with a circumferential groove and an annular groove, the circumferential groove is provided along the circumference of the fixed disk and opens outward, the annular groove is provided in the fixed disk and communicates with the circumferential groove, and the angle between the opening direction of the circumferential groove and the opening direction of the annular groove is a right angle, an acute angle or an obtuse angle. The wedge-shaped portion of the blade root of the intercepting blade is used to be inserted into the circumferential groove, and the clamping portion is used to be clamped to the annular groove.

[0219] Specifically, Fig.182 shows an exploded schematic diagram of the upper fixed disk part 22 and the lower fixed disk part 21 and an internal view of the two connected together. The fixed disk 2 is a circular disk, and the fixed disk 2 includes a lower fixed disk part 21 and an upper fixed disk part 22. The upper fixed disk part 22 is connected to the lower fixed disk part 21 in a cooperative manner so as to form the circumferential groove 21c in the circumferential direction of the upper fixed disk part and the lower fixed disk part. The angle between the opening direction of the annular groove 21a and the opening direction of the circumferential groove 21c can be a right angle, so that when a plurality of intercepting blades are installed on the fixed disk, the upper surface of the plurality of intercepting blades 1 is approximately parallel to the upper surface of the fixed disk, and the lower surface of the plurality of intercepting blades is approximately parallel to the lower surface of the fixed disk, that is, the upper surface and the lower surface of the oil fume separation disk are approximately planes, so that when the oil fume separation disk is rotated, the balance of the oil fume separation disk is better.

[0220] More specifically, the upper fixed disk portion 21 and the lower fixed disk portion 22 are both circular disk-shaped structures, the center of the upper fixed disk portion 21 is collinear with the center of the lower fixed disk portion 22, the upper fixed disk portion 21 is provided with a first protrusion 21b protruding toward the lower fixed disk portion 22, the center of the first protrusion 21b is collinear with the center of the upper fixed disk portion 21, and the annular groove 21a is formed between the first protrusion 21b and the upper fixed disk portion 21. The clamping portion of the blade root portion 1c of the intercepting fan blade 1 is clamped in the annular groove 21a to achieve the connection between the intercepting fan blade 1 and the upper fixed disk portion 21. Specifically, the clamping portion 14 of the blade root portion 1c is provided with a bayonet corresponding to the annular groove 21a, and the bayonet is clamped in the annular groove 21a.

[0221] Furthermore, in order to facilitate the connection between the lower fixed disk part 22 and the upper fixed disk part 21, a first positioning groove 211 is provided on the first protrusion 21b of the upper fixed disk part 21, and the lower fixed disk part 22 is provided with a second protrusion (not shown) corresponding to the first protrusion 21b, and the second protrusion is also provided with a positioning protrusion (not shown) corresponding to the first positioning groove 211. When the lower fixed disk part 22 is connected to the upper fixed disk part 21, the positioning protrusion is engaged in the first positioning groove 211. In this way, the alignment connection between the upper fixed disk part 21 and the lower fixed disk part 22 can be facilitated. In addition, the method of engaging the positioning protrusion with the first positioning groove 211 is also conducive to preventing the upper fixed disk part 21 and the lower fixed disk part 22 from shifting during the high-speed rotation process, thereby affecting the effect of intercepting the fan blade 1 to separate the oil smoke.

[0222] In this embodiment, the plurality of intercepting blades 1 are arranged in a ring shape along the center of the fixed disk 2, and along the height extension direction of the fixed disk 2, the plurality of intercepting blades 1 can be arranged in a single layer or multiple layers on the fixed disk 2. Fig.16 As shown, Fig.16The figure shows that the plurality of intercepting blades 1 are arranged in a single layer on the fixed disk 2. Since the fixed disk 2 is a circular disk structure, the intercepting blades 1 are arranged in a ring along the center of the fixed disk 2. Along the height extension direction A of the fixed disk 2, the intercepting blades 1 can be designed as an upper and lower two-layer design, and there should be a spacing between the two layers of intercepting blades 1 to avoid the upper and lower layers of intercepting blades 1 contacting each other and affecting the rotation during high-speed rotation. It can be understood that in other embodiments, the number of layers of the intercepting blades 1 on the fixed disk 2 can also be three layers, four layers or more layers, etc.

[0223] In addition, it can be known that when the intercepting fan blades 1 are designed as two layers, the upper and lower layers of the intercepting fan blades 1 can be placed in the same or opposite directions. For example, the upper and lower layers of the intercepting fan blades 1 have the same placement direction, the first angle α of the upper and lower layers of the intercepting fan blades 1 are in the same direction, or the upper and lower layers of the intercepting fan blades 1 can also be placed in the same direction, that is, the first angle α of the upper and lower layers of the intercepting fan blades 1 are in opposite directions.

[0224] The separation disk provided in the fifth embodiment of the present invention adopts an intercepting wind blade with a V-shaped cross-section, and the first side surface of the first blade part and the third side surface of the second blade part are limited to be located in the same plane, thereby facilitating the processing and production of the intercepting wind blade; at the same time, the evenly or unevenly arranged raised structure is arranged at the intersection of the first blade part and the second blade part, so that the collision probability of the oil smoke at the raised structure is increased when the oil smoke passes through the raised structure, so that more oil droplets are separated and the separation effect is better.

[0225] In addition, the separation plate 200 provided in the fifth embodiment of the present invention can improve the oil fume separation rate as much as possible without affecting the oil fume separation efficiency by limiting the relationship between the protrusion height of the long strip protrusion and the gap 1d formed by the interception fan blade 1 and the relationship between the protrusion height and the interception fan blade 1 itself, thereby effectively optimizing the separation effect.

[0235] Embodiment 8

[0236] Please refer again Figures 14 to 15 as well as Fig.16 The eighth embodiment of the present invention discloses a separation disc.

[0241] Specifically, the driving mechanism 300 may be a motor, the rotating shaft of the motor is fixedly connected to the fixed disk 2 of the separation disk 200, thereby driving the fixed disk 2 to rotate and then driving the plurality of intercepting blades 1 to rotate through the fixed disk 2.

[0242] Furthermore, when the separation disc 200 is applied to a dynamic interceptor, it can be placed in the oil fume channel of the dynamic interceptor. When the oil fume enters the position of the separation disc 200 through the oil fume channel, it can be intercepted by the interception fan blades 1 of the separation disc 200 and the oil droplets and solid particles in the oil fume can be thrown out, so that the final discharged gas does not contain or basically does not contain grease and / or solid particles.
