Description

Technical Field

[0001] The invention relates to the technical field of bulk material structures, in particular to a vertical cement raw material mill spraying device. Background Art

[0002] Vertical cement raw mill, as the core equipment in the modern cement production process, is widely used to grind and mix various raw materials (such as limestone, clay, iron powder, etc.) into homogeneous raw powder. Compared with traditional ball mills, vertical mills have higher grinding efficiency, lower energy consumption and stronger drying capacity, so they are rapidly promoted and applied in the cement industry.

[0003] During the operation of the vertical cement raw mill, the uniform distribution and reasonable feeding of materials are the key factors to ensure the quality and efficiency of grinding. Therefore, a spraying structure is required in the raw mill to facilitate the uniform diffusion of the raw materials into the grinding bed in the raw mill. The existing spraying structure mainly includes a rotating disc and a guide plate arranged at the edge of the disc. When the material is evenly distributed, the raw material falls onto the rotating disc, and the disc centrifugally diffuses the raw material around and scatters the raw material downward into the raw mill through the guide plate, thereby realizing the material dispersion work. In actual application, it also exposes some technical problems, such as the raw material can only be scattered from the edge of the disc. From a bird's-eye view, the scattering trajectory of the raw material is circular, that is, the raw material falls in a linear shape rather than a surface shape, resulting in the raw material being more concentrated and its dispersion is poor.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0034] like Figures 1 to 7 As shown, the vertical cement raw meal mill spraying device of the present invention comprises a feed pipe 1, a first disc 2 and a second disc 3, the first disc 2 and the second disc 3 are distributed up and down, and the first disc 2 and the second disc 3 are coaxially arranged, the space between the first disc 2 and the second disc 3 is set as a material mixing space, the feed pipe 1 is vertically installed on the top of the first disc 2 and is used to feed into the material mixing space, a retaining ring 4 is arranged at the edge of the second disc 3, the first disc 2 is in contact with the retaining ring 4, and a plurality of scattering The bulk material long slot plate 5 has a length direction along the radial direction of the second disc 3, and the bulk material long slot plate 5 is connected with the material sizing space. A long opening for discharging is provided at the bottom of the bulk material long slot plate 5, and the length direction of the long opening is along the radial direction of the second disc 3. A first rotating shaft 6 is rotatably provided inside the bulk material long slot plate 5, and a plurality of partitions 7 are provided on the outer wall of the first rotating shaft 6. The space between two adjacent partitions 7 is used to store raw materials. When two adjacent partitions 7 are in contact with the inner wall of the bulk material long slot plate 5, the space formed between the two adjacent partitions 7 is sealed.

[0035] The second disc 3 rotates and is used to diffuse the raw materials in the mixing space outwards. The middle of the mixing space is set to be conical, and the edge of the mixing space is set to be a horizontal ring. Multiple bulk material long slot plates 5 are all located in the ring area of ​​the mixing space.

[0036] In detail, the first disc 2, the second disc 3 and the baffle ring 4 form a closed space, and the mixing space between the first disc 2 and the second disc 3 is flat, so that the flow rate of the raw material can be easily limited. The feed pipe 1 is used to supply the raw material to the mixing space between the first disc 2 and the second disc 3. Since the middle part of the mixing space is conical, it is convenient to transport the raw material from the middle part of the mixing space to the area where the multiple bulk material long slot plates 5 are located. At the same time, since the second disc 3 can rotate, it can avoid that when the raw material is in the middle of the mixing space, the second disc 3 has a poor centrifugal effect on the raw material and causes the raw material to be blocked in the middle of the mixing space, so that the raw material can be quickly diffused to the surroundings. When the raw material moves to the position of the bulk material long trough plate 5, the raw material falls between two adjacent partitions 7 in the bulk material long trough plate 5, and the raw material fills the space between the two adjacent partitions 7. As the first rotating shaft 6 rotates, the first rotating shaft 6 carries the two adjacent partitions 7 and the raw materials therebetween and transports them downward. When the raw material moves to the long opening position at the bottom of the bulk material long trough plate 5, the raw material is scattered downward through the long opening. At this time, the raw material falls in a linear shape. Since the length direction of the long opening is along the radial direction of the second disc 3, and the second disc 3 rotates, the raw material falling in a linear shape follows the second disc 3 in synchronous circular motion, so that the raw material falls in a planar shape, realizing a uniform bulking working mode of the raw material.

[0037] It should be pointed out that since the second disc 3 rotates and the raw materials on it are centrifugally dispersed in all directions, in order to prevent the raw materials from jumping off the second disc 3 at will and to avoid inconsistent thickness of the raw materials on the second disc 3, it is necessary to use the first disc 2 to restrict the raw materials, which can prevent the raw materials from jumping and dispersing at will and limit the thickness of the raw materials on the second disc 3, so as to make it convenient to keep the thickness of the raw materials between the first disc 2 and the second disc 3 consistent, thereby improving the uniformity of the bulk material.

[0038] In actual use, since the raw materials are pushed by the centrifugal force of the second disc 3 and enter between two adjacent partitions 7, and the two partitions 7 will rotate with the first rotating shaft 6, even if the raw materials between two adjacent partitions 7 are not filled, the raw materials can still be evenly distributed between the two adjacent partitions 7 during the process of transporting the raw materials, thereby ensuring that the pigment discharged from the long mouth is uniform, and the arrangement of the first rotating shaft 6 and multiple partitions 7 can prevent the raw materials in the material mixing space from directly entering the bulk material long groove plate 5 and being discharged through the long mouth, thereby avoiding the aggregation of raw materials discharged from the long mouth and the inability to achieve uniform material discharge.

[0039] By designing the second disc 3 to rotate and diffuse the raw materials outward, combined with the annular distribution of multiple bulk material long slot plates 5, the raw materials are not only evenly scattered in the circumferential direction, but also more widely distributed in the radial direction. This "surface-like" falling method greatly improves the uniformity of the distribution of the raw materials in the raw mill, which is beneficial to improving the quality and efficiency of grinding; the conical design in the middle of the material-leveling space helps the raw materials to flow smoothly to the surroundings, avoids the accumulation of raw materials in the central area, and improves the fluidity of the raw materials. In addition, through the cooperation of the first rotating shaft 6 and the partition 7, the raw materials can be accurately controlled and evenly distributed to each bulk material long slot plate 5, further improving the efficiency and accuracy of raw material processing; the existence of the first disc 2 not only limits the flow range of the raw materials, but also plays a role in limiting the thickness of the raw materials, ensuring that the thickness of the raw material layer on the second disc 3 is uniform, which is crucial to maintaining the uniform distribution of the raw materials in the mill; in summary, the spraying device effectively solves the problems of uneven raw material distribution and low processing efficiency existing in the traditional spraying structure through innovative structural design, and provides strong support for the efficient and stable operation of the cement raw mill.

[0040] like Figure 7 As shown, the first rotating shaft 6 is hollow inside, an exhaust port 8 is opened on the outer wall of the first rotating shaft 6 between two adjacent partitions 7, an arc-shaped baffle 9 is arranged inside the first rotating shaft 6, both ends of the arc-shaped baffle 9 are fixed on the side wall of the bulk material long slot plate 5, and the opening of the arc-shaped baffle 9 faces downward;

[0041] Among them, when the exhaust port 8 rotates to the opening position of the arc-shaped baffle 9, the exhaust port 8 is connected to the inside of the first rotating shaft 6. When the exhaust port 8 deviates from the opening position of the arc-shaped baffle 9, the arc-shaped baffle 9 blocks the exhaust port 8, and the high-pressure gas in the first rotating shaft 6 is ejected downward through the opening of the arc-shaped baffle 9, that is, the exhaust port 8 at the bottom of the first rotating shaft 6.

[0042] In detail, the first rotating shaft 6 is in the shape of a tube, and both ends of the first rotating shaft 6 are rotatably mounted on the inner wall of the bulk material long groove plate 5. The arc baffle 9 is located on the inner side of the first rotating shaft 6, and both ends of the arc baffle 9 are fixed on the inner wall of the bulk material long groove plate 5. The first rotating shaft 6 stores high-pressure gas. When the first rotating shaft 6 rotates and conveys raw materials, the exhaust port 8 moves with the raw materials to the bottom of the first rotating shaft 6. At this time, the exhaust port 8 is located at the opening position of the arc baffle 9, and the high-pressure gas in the first rotating shaft 6 is ejected downward through the exhaust port 8. The high-pressure gas can discharge the raw materials between the two adjacent partitions 7, thereby avoiding the accumulation of raw materials. At the same time, the discharged high-pressure gas can have a blowing effect on the raw materials, thereby facilitating the dispersion of the raw materials over a large area and improving the raw material bulking effect. When the exhaust port 8 deviates from the bottom opening of the arc baffle 9, the arc baffle 9 blocks the exhaust port 8. At this time, the high-pressure gas in the first rotating shaft 6 cannot be discharged through the exhaust port 8.

[0043] The above structural method can realize the spraying of raw materials.

[0044] like Figure 8 As shown, a rotating tube 10 is rotatably provided on the end surface of the bulk material long groove plate 5 facing the axis of the second disc 3, and a through-port is opened on the end surface of the bulk material long groove plate 5 inside the rotating tube 10. The rotating tube 10 is connected with the first rotating shaft 6 through the through-port, and an auxiliary shaft 11 is rotatably installed in the through-port. First transmission wheels 12 are provided at both ends of the auxiliary shaft 11, one of the first transmission wheels 12 is transmission-connected to the inner wall of the rotating tube 10, and the other first transmission wheel 12 is located at the opening position of the arc baffle 9, and the first transmission wheel 12 is transmission-connected to the inner wall of the first rotating shaft 6, and high-pressure gas is supplied into the first rotating shaft 6 through the rotating tube 10 and the through-port.

[0045] In detail, the rotating tube 10 is rotatably installed on the end surface of the bulk material long groove plate 5, and a through hole is opened on the local side wall of the bulk material long groove plate 5 between the rotating tube 10 and the first rotating shaft 6, and the through hole is used to connect the rotating tube 10 and the first rotating shaft 6. High-pressure gas can be supplied into the first rotating shaft 6 through the rotating tube 10 and the through hole. At the same time, when the rotating tube 10 rotates, the rotating tube 10 can drive the first rotating shaft 6 to rotate synchronously through the auxiliary shaft 11 and the two first transmission wheels 12, thereby realizing the rotational movement of the first rotating shaft 6 and multiple partitions 7.

[0046] It should be pointed out that this structural design can fix both ends of the arc baffle 9, while in the traditional method, the first rotating shaft 6 and the rotating tube 10 are designed as the same structure, which can only fix one end of the arc baffle 9, and its structural, sealing and firmness are poor.

[0047] like Figures 4 to 8 As shown, a support plate 13 is provided in the feed pipe 1, the cross-section of the support plate 13 is triangular, and its opening is downward, a second rotating shaft 14 is fixed in the support plate 13, a power sleeve 15 is rotatably sleeved on the outer wall of the second rotating shaft 14, the power sleeve 15 is connected to the second disc 3, and the bottom of the second rotating shaft 14 passes through the second disc 3, the second rotating shaft 14 and the second disc 3 rotate relative to each other, a transmission disc 16 is provided on the second rotating shaft 14, and a second transmission wheel 17 is provided on each rotating tube 10, and the second transmission wheel 17 is transmission-connected to the transmission disc 16;

[0048] The support plate 13 is provided with a first motor 18 and a third transmission wheel 19 for providing rotational power to the power sleeve 15 .

[0049] In detail, the second rotating shaft 14 and the first motor 18 are both fixed inside the support plate 13. The shape of the support plate 13 can be used to divert and block raw materials. The support plate 13 and the second rotating shaft 14 can provide support for the transmission disk 16. The third transmission wheel 19 is installed on the output end of the first motor 18, and the third transmission wheel 19 is connected to the side wall of the power sleeve 15. The first motor 18 drives the power sleeve 15 to rotate through the third transmission wheel 19. The power sleeve 15 will drive the second disc 3 to rotate, thereby providing power for the second disc 3. At the same time, the second disc 3 will drive the bulk material long groove plate 5 to move synchronously. The bulk material long groove plate 5 drives the second transmission wheel 17 thereon to roll on the transmission disk 16, thereby providing power for the rotation of the rotating tube 10 and the first rotating shaft 6.

[0050] like Figures 4 to 5 As shown, the second rotating shaft 14 is hollow, and the feed pipe 1 is provided with an air intake hose 20 which is connected with the second rotating shaft 14 and is used to supply high-pressure gas to the inside of the second rotating shaft 14. An air guide chamber 21 is provided on the bottom rotating sleeve of the second rotating shaft 14, and a plurality of air guide holes 22 are opened on the outer wall of the second rotating shaft 14 inside the air guide chamber 21. The second rotating shaft 14 is connected with the air guide chamber 21 through the air guide holes 22. A plurality of air guide pipes 23 are provided on the air guide chamber 21, and the air guide pipes 23 are connected with the rotating tube 10, and the rotating tube 10 and the air guide pipes 23 rotate relative to each other.

[0051] In detail, high-pressure gas can be supplied into the second rotating shaft 14 through the air intake hose 20, and the high-pressure gas in the second rotating shaft 14 is discharged into the air guide chamber 21 through multiple air guide holes 22 and discharged into each rotating tube 10 through multiple air guide pipes 23, thereby realizing the supply of high-pressure gas.

[0052] When the rotating tube 10 rotates along with the second disk 3, the rotating tube 10 drives the air guide chamber 21 to rotate on the second rotating shaft 14 through the air guide tube 23. When the rotating tube 10 rotates, the rotating tube 10 rotates relative to the air guide tube 23. At this time, the rotating tube 10 and the air guide tube 23 remain connected.

[0053] The retaining ring 4 and the first disc 2 slide relative to each other in the vertical direction, and an adjustment structure is provided on the feeding pipe 1, and the adjustment structure is used to adjust the height position of the retaining ring 4 and the second disc 3;

[0054] The support plate 13 slides vertically on the inner wall of the feeding pipe 1 .

[0055] In detail, the adjustment structure can drive the baffle ring 4 to move up and down, thereby driving the second disc 3 to move up and down. At this time, the size of the material mixing space between the second disc 3 and the first disc 2 changes, thereby adjusting the raw material thickness and raw material supply speed in the material mixing space. When the second disc 3 moves up and down, it can push the support plate 13 to move up and down synchronously in the feed pipe 1 through the second rotating shaft 14 and the power sleeve 15.

[0056] like Figure 3 As shown, the adjustment structure includes a thread arranged on the outer wall of the feed pipe 1 and a threaded ring 24 screwed on the thread, a first connecting ring 25 is rotatably sleeved on the threaded ring 24, a second connecting ring 26 is rotatably arranged on the inner wall of the retaining ring 4, and the first connecting ring 25 and the second connecting ring 26 are connected by a plurality of first oblique arms 27;

[0057] The feed pipe 1 is provided with a second motor 28 , and an output end of the second motor 28 is provided with a tooth column 29 . The outer wall of the threaded ring 24 is provided with teeth, and the tooth column 29 meshes with the teeth on the threaded ring 24 .

[0058] In detail, one end of the first inclined arm 27 is rotatably mounted on the first connecting ring 25, and the other end of the first inclined arm 27 is rotatably mounted on the second connecting ring 26. When the second motor 28 drives the gear column 29 to rotate, the gear column 29 can drive the threaded ring 24 to rotate. Since the threaded ring 24 is screwed to the thread on the feed pipe 1, the threaded ring 24 moves up and down. The threaded ring 24 drives the second connecting ring 26 to move up and down synchronously through the first connecting ring 25 and multiple first inclined arms 27. The second connecting ring 26 drives the retaining ring 4 to move up and down, thereby adjusting the height position of the second disc 3.

[0059] Since the second disk 3 and the blocking ring 4 need to be able to rotate, the blocking ring 4 is rotatably connected to the second connecting ring 26 .

[0060] like Figure 3 As shown, a sliding sleeve 30 is slidably mounted on each of the first oblique arms 27 , and the sliding sleeve 30 is connected to the first disc 2 via a second oblique arm 31 .

[0061] In detail, the second oblique arm 31 is tilted, one end of the second oblique arm 31 is rotatably mounted on the sleeve 30, and the other end of the second oblique arm 31 is rotatably mounted on the first disc 2. When the first oblique arm 27 tilts, the first oblique arm 27 slides relative to the sleeve 30, and the first oblique arm 27 drives the second oblique arm 31 to tilt through the sleeve 30. The position of the first oblique arm 27 can be limited by the sleeve 30 and the second oblique arm 31, thereby preventing the first oblique arm 27 from rotating on the first disc 2.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
