Description

Technical Field

[0001] The utility model relates to the technical field of material conveying equipment, in particular to a blanking device. Background Art

[0002] In the prior art, as shown in Figure 1 , in a cut tobacco production line, an in-situ air separation and impurity removal machine 01 utilizes the difference in suspension speeds between cut tobacco and impurities, removes impurities by means of wind, and conveys the cut tobacco meeting the process requirements after impurity removal to a downstream belt conveyor 03 through the belt of the equipment itself. Since the width of the downstream belt conveyor 03 is relatively small, a "reverse frustum-shaped" blanking device 02 is used for connection between the in-situ air separation and impurity removal machine 01 and the downstream belt conveyor 03.

[0003] At present, the cut tobacco conveyed to the downstream belt conveyor 03 through the blanking device 02 has the following deficiencies:

[0004] Uneven blanking: As shown in Figure 2 , since the width of the belt of the in-situ air separation and impurity removal machine 01 itself is greater than the width of the belt conveyor 03, most of the cut tobacco will slide along the side wall of the blanking device 02 and be conveyed to both sides of the belt conveyor 03 when passing through the blanking device 02, resulting in a cloth state where the cut tobacco on the belt of the belt conveyor 03 is high on both sides and low in the middle, and there is a problem of uneven transverse blanking.

[0005] Exposed cut tobacco causes fluctuations in moisture detection: The detection point of the moisture detection device is set in the middle of the belt of the belt conveyor 03. Due to uneven transverse blanking, there is often no material in the middle of the belt, resulting in fluctuations in moisture detection and affecting production operations. Summary of the Utility Model

[0006] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the utility model is to provide a blanking device that can achieve uniform transverse blanking.

[0007] To solve the above technical problems, the utility model adopts the following technical solutions:

[0008] The utility model provides a blanking device, which includes a blanking shell. A blanking cavity is formed through the blanking shell in the up-down direction. An inlet is formed at the upper end of the blanking cavity, and an outlet is formed at the lower end of the blanking cavity.

The blanking cavity has two side wall surfaces that are transversely opposite to each other perpendicular to the conveying direction of the belt conveyor. Both side wall surfaces include a first wall surface and a second wall surface that are longitudinally adjacent to each other in sequence parallel to the conveying direction of the belt conveyor. The first wall surface is inclined towards the inside of the blanking cavity relative to the second wall surface from the inlet to the outlet.

[0009] Preferably, the angle at which the first wall surface of at least one side wall surface inclines towards the inside of the blanking cavity relative to the second wall surface is adjustable.

[0010] Preferably, the blanking housing includes a first baffle, a second baffle, and two blanking plates. The first baffle and the second baffle are oppositely arranged at intervals longitudinally, and the two blanking plates are oppositely arranged at intervals transversely. The two blanking plates are both connected to the first baffle and the second baffle to enclose a blanking cavity. Two first wall surfaces are respectively arranged on the two blanking plates, and two second wall surfaces are both arranged on the first baffle.

[0011] Preferably, the blanking plate has a receiving plate. The surface of the receiving plate facing the blanking cavity constitutes the first wall surface. The two opposite sides of the receiving plate in the longitudinal direction are respectively bent to form a first wing portion and a second wing portion. The first baffle includes a transverse plate, a side plate, and a connecting portion. The two opposite sides of the transverse plate in the transverse direction are both bent towards the blanking plate to form side plates. The surface of the side plate facing the blanking cavity constitutes the second wall surface. The side of the side plate away from the transverse plate is bent to form a connecting portion, and the connecting portion is connected to the first wing portion, and the second wing portion is connected to the second baffle.

[0012] Preferably, the first wing portion and the second wing portion of at least one blanking plate are respectively in sliding fit with the connecting portion and the second baffle, so that the blanking plate is rotatably arranged between the first baffle and the second baffle around the upper end of the blanking plate.

[0013] Preferably, the first wing portion and the connecting portion are connected through an adjusting structure, or both the first wing portion and the connecting portion, and the second wing portion and the second baffle are connected through an adjusting structure. The adjusting structure is used to adjust the rotation angle of the blanking plate and fix the blanking plate to the first baffle or the second baffle.

[0014] Preferably, the adjusting structure includes a connecting member, a connecting hole, and a long hole. The connecting hole and the long hole are respectively arranged on the first wing portion and the connecting portion or respectively arranged on the second wing portion and the second baffle. The connecting member connects the connecting hole and the long hole, and the position of the connecting member in the long hole is adjustable.

[0015] Preferably, it further includes a cover housing. The cover housing is used to be placed above the belt conveyor and form a blanking space with the belt conveyor. The lower end of the blanking housing is connected to the cover housing, and the discharge port is communicated with the blanking space.

[0016] Preferably, the lower end of the first wall surface extends towards the inside of the blanking space, and the lower end of the first wall surface remains inside the blanking space during the process of adjusting the angle at which the first wall surface inclines towards the inside of the blanking cavity relative to the second wall surface.

[0017] Preferably, it further includes a mounting plate. The mounting plate is arranged at the upper end of the blanking housing and is connected to the outer periphery of the feed port.

[0018] Compared with the prior art, the utility model has remarkable progress:

[0019] For the blanking device of the present utility model, by designing the two side wall surfaces of the blanking cavity of the blanking shell that are opposite to each other in the horizontal direction to include a first wall surface and a second wall surface that are adjacent to each other in sequence in the vertical direction, and the first wall surface inclines towards the inside of the blanking cavity relative to the second wall surface from the feed inlet to the discharge outlet, so that the discharge outlet is jointly constituted by a first outlet formed by the lower ends of the two first wall surfaces being relatively spaced apart and a second outlet formed by the lower ends of the two second wall surfaces being relatively spaced apart, and the two side edges of the first outlet that are opposite to each other in the horizontal direction are closer to the horizontal center of the discharge outlet than the two side edges of the second outlet that are opposite to each other in the horizontal direction, and thus closer to the center position of the material receiving area. Therefore, after the material enters the blanking cavity from the feed inlet, the materials close to the two side wall surfaces of the blanking cavity that are opposite to each other in the horizontal direction slide down along the first wall surface and the second wall surface respectively. The material sliding along the first wall surface falls onto the material receiving area from the first outlet, and the material sliding along the second wall surface falls onto the material receiving area from the second outlet. The material falling from the first outlet is more concentrated in the horizontal direction closer to the center of the material receiving area than the material falling from the second outlet, so as to realize that the material is horizontally evenly distributed after falling from the discharge outlet onto the material receiving area.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0057] In addition, in the description of the present utility model, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0058] As Figures 3 to 7 shown, it is an embodiment of the blanking device of the present utility model.

[0059] See Figure 3 、 Figure 6 and Figure 7, the blanking device of this embodiment includes a blanking housing 1. A blanking chamber 10 is formed through the blanking housing 1 in the vertical direction. An inlet 11 is formed at the upper end of the blanking chamber 10, and an outlet 12 is formed at the lower end of the blanking chamber 10. The outlet 12 is used to be placed above the belt conveyor 03 to output materials to the belt conveyor 03. The blanking housing 1 is the main part of the blanking device, preferably made of rigid material to withstand the weight of the materials and the impact force generated during the blanking process. The inlet 11 is the opening at the upper end of the blanking chamber 10, used to receive materials from above and ensure the smooth entry of materials into the blanking chamber 10. The outlet 12 is the opening at the lower end of the blanking chamber 10, placed opposite to the material receiving area of the belt conveyor 03 in the vertical direction. The blanking chamber 10 is the internal space of the blanking housing 1 and is the passage for materials to pass through the blanking housing 1. The overall shape of the blanking chamber 10 is in the shape of an inverted frustum. Therefore, the cross-sectional area of the blanking chamber 10 gradually decreases from the inlet 11 to the outlet 12. In this way, the blanking chamber 10 can receive more materials output from the larger material output area of the previous process through the larger inlet 11 and convey the materials to the belt conveyor 03 with a smaller material receiving area in the next process through the smaller outlet 12.

[0060] The blanking device of this embodiment can be used for the connection between the existing in-situ air separation and impurity removal machine 01 and the belt conveyor 03, that is, to replace Figure 2 the existing blanking device 02 shown in the figure is arranged between the in-situ air separation and impurity removal machine 01 and the belt conveyor 03, and the inlet 11 and the outlet 12 are respectively connected to the in-situ air separation and impurity removal machine 01 and the belt conveyor 03 to convey the materials output from the in-situ air separation and impurity removal machine 01 to the belt conveyor 03. It should be noted that in the description of the present utility model, the "upper" side refers to Figure 2 the upper side of the paper surface, the "lower" side refers to Figure 2 the lower side of the paper surface, the "front" side refers to Figure 2 the outer side of the paper surface, the "rear" side refers to Figure 2 the inner side of the paper surface, the "left" side refers to Figure 2 the left side of the paper surface, the "right" side refers to Figure 2 the right side of the paper surface; the conveying direction of the belt conveyor 03 is along the front-rear direction. The "lateral" direction refers to the direction perpendicular to the conveying direction of the belt conveyor 03 on the plane where the belt of the belt conveyor 03 is located, and the "lateral" direction is also the left-right direction; the "longitudinal" direction refers to the direction parallel to the conveying direction of the belt conveyor 03, and the "longitudinal" direction is also the front-rear direction.

[0061] In this embodiment, the blanking chamber 10 has two side wall surfaces oppositely arranged in the transverse direction. Both side wall surfaces include a first wall surface 13 and a second wall surface 14 that are successively adjacent in the longitudinal direction. The lower ends of the two first wall surfaces 13 are spaced apart relatively to form a first outlet 121, and the lower ends of the two second wall surfaces 14 are spaced apart relatively to form a second outlet 122. The first outlet 121 and the second outlet 122 together constitute the discharge port 12. The first wall surface 13 is inclined downward into the interior of the blanking chamber 10 relative to the second wall surface 14 from the feed port 11 to the discharge port 12, such that the transverse length of the first outlet 121 is smaller than the transverse length of the second outlet 122, and the two opposite sides in the transverse direction of the first outlet 121 are closer to the transverse center of the discharge port 12, and thus closer to the center of the material receiving area, than the two opposite sides in the transverse direction of the second outlet 122.

[0062] Accordingly, after the material enters the blanking chamber 10 from the feed port 11, the materials near the two side wall surfaces oppositely arranged in the transverse direction of the blanking chamber 10 slide downward along the first wall surface 13 and the second wall surface 14 respectively. The material sliding along the first wall surface 13 falls onto the material receiving area from the first outlet 121, and the material sliding along the second wall surface 14 falls onto the material receiving area from the second outlet 122. Since the two opposite sides in the transverse direction of the first outlet 121 are closer to the center of the material receiving area than the two opposite sides in the transverse direction of the second outlet 122, the material falling from the first outlet 121 is more concentrated transversely closer to the center of the material receiving area than the material falling from the second outlet 122, thereby achieving a transverse uniform distribution of the material after it falls from the discharge port 12 onto the material receiving area.

[0063] See Figures 3 to 5 , preferably, among the two side wall surfaces oppositely arranged in the transverse direction of the blanking chamber 10, the inclination angle of the first wall surface 13 relative to the second wall surface 14 of at least one side wall surface is adjustable. By adjusting the inclination angle of the first wall surface 13, the transverse length of the first outlet 121 can be increased or decreased. Therefore, the material falling along the two opposite sides in the transverse direction of the first outlet 121 can be further closer to or farther from the center of the material receiving area, thereby adjusting the cloth distribution of the material after it falls onto the material receiving area.

[0064] See Figures 3 to 5, preferably, the blanking housing 1 includes a first baffle 3, a second baffle 4 and two blanking plates 2. The first baffle 3 and the second baffle 4 are arranged oppositely at intervals longitudinally, and the two blanking plates 2 are arranged oppositely at intervals transversely. The two blanking plates 2 are both connected to the first baffle 3 and the second baffle 4 to enclose a blanking cavity 10. Two first wall surfaces 13 are respectively arranged on the two blanking plates 2, and two second wall surfaces 14 are both arranged on the first baffle 3. Since the first wall surface 13 inclines downward into the blanking cavity 10 relative to the second wall surface 14 from the feed inlet 11 to the discharge outlet 12, the part of the lower end of the blanking plate 2 that forms the first outlet 121 is closer to the center of the material receiving area transversely than the part of the first baffle 3 that forms the second outlet 122. When the material is being transported, it enters the blanking cavity 10 from above the blanking housing 1 through the feed inlet 11. Then, a small part of the material in the central area of the feed inlet 11 directly falls to the central position of the material receiving area. A part of the material falls onto the first wall surface 13 of the blanking plate 2, and then slides along the first wall surface 13 and falls onto the material receiving area from the two opposite lateral sides of the first outlet 121. The remaining part of the material falls onto the second wall surface 14 of the first baffle 3, and then slides along the second wall surface 14 and falls onto the material receiving area from the two opposite lateral sides of the second outlet 122. The material falling from the first outlet 121 is closer to the center of the material receiving area transversely than the material falling from the second outlet 122. Thus, the material falling onto the material receiving area is evenly distributed transversely as a whole.

[0065] Furthermore, among the two blanking plates 2, at least one blanking plate 2 is rotatably arranged between the first baffle 3 and the second baffle 4 around the upper end of the blanking plate 2, so that the inclination angle of the first wall surface 13 on this blanking plate 2 relative to the second wall surface 14 downward into the blanking cavity 10 can be adjusted. When the transport flow rate of the material changes, causing the total amount of material entering the blanking cavity 10 to increase or decrease within the same time, the cloth distribution of the material also changes accordingly. At this time, the blanking plate 2 can be rotated according to the actual cloth distribution situation to adjust the inclination angle of the first wall surface 13: when most of the material is distributed at the position transversely close to the edge of the material receiving area after falling, the blanking plate 2 can be rotated into the blanking cavity 10 to make the material sliding and falling along the first wall surface 13 closer to the center of the material receiving area; when most of the material is distributed at the position transversely close to the center of the material receiving area after falling, the blanking plate 2 can be rotated out of the blanking cavity 10 to make the material sliding and falling along the first wall surface 13 away from the center of the material receiving area. By rotating the blanking plate 2, the material can be evenly blanked transversely after passing through the blanking housing 1.

[0066] See Figures 3 to 5, preferably, the blanking plate 2 has a receiving plate 20. The side of the receiving plate 20 facing the blanking cavity 10 constitutes the first wall surface 13. The two opposite longitudinal sides of the receiving plate 20 are respectively bent to form a first wing portion 21 and a second wing portion 22. The first baffle 3 includes a transverse plate 30, side plates 31 and a connecting portion 32. The two opposite transverse sides of the transverse plate 30 are both bent towards the blanking plate 2 to form side plates 31. The side of the side plate 31 facing the blanking cavity 10 constitutes the second wall surface 14. The side of the side plate 31 away from the transverse plate 30 is bent to form a connecting portion 32. One side of the receiving plate 20 is connected to the connecting portion 32 on the side plate 31 through the first wing portion 21, and the other side of the receiving plate 20 is connected to the second baffle 4 through the second wing portion 22. Thus, the connection between the blanking plate 2 and the first baffle 3 and the second baffle 4 is realized, avoiding the formation of protrusions or gaps on the receiving plate 20 and the side plate 31, making the first wall surface 13 and the second wall surface 14 into continuous and flat planes. Therefore, the material can smoothly slide on the first wall surface 13 and the second wall surface 14 and pass through the blanking cavity 10. At the same time, the blanking plate 2 is tightly connected to the first baffle 3 and the second baffle 4 through the first wing portion 21 and the second wing portion 22 respectively, which is beneficial to improving the stability of the whole blanking housing 1 under the impact or vibration of the material, making the first baffle 3, the second baffle 4 and the two blanking plates 2 form a solid frame through mutual connection and stably maintaining the overall structure of the blanking housing 1.

[0067] See Figures 3 to 5 , preferably, the first wing portion 21 and the second wing portion 22 of at least one blanking plate 2 are respectively in sliding fit with the connecting portion 32 and the second baffle 4, so that the blanking plate 2 is rotatably arranged between the first baffle 3 and the second baffle 4 around the upper end of the blanking plate 2. Rotating the blanking plate 2 according to the actual blanking situation of the material can adjust the angle of the first wall surface 13 relative to the second wall surface 14 inclined towards the inside of the blanking cavity 10, and further adjust the position of the material sliding along the first wall surface 13 and conveyed to the material receiving area, so that the material is evenly blanked laterally after passing through the blanking housing 1. Further, both the first wing portion 21 and the second wing portion 22 are bent towards the outside of the blanking cavity 10 and perpendicularly intersect with the receiving plate 20 after bending. The connecting portion 32 is bent towards the inside of the blanking cavity 10 and is parallel to the transverse plate 30 after bending. The second baffle 4 is in a flat plate shape. The first wing portion 21 is parallel and in fitting connection with the connecting portion 32, and the second wing portion 22 is parallel and in fitting connection with the second baffle 4. During the process of rotating the blanking plate 2, the first wing portion 21 and the connecting portion 32, and the second wing portion 22 and the second baffle 4 all remain in a fitting state, so that the internal space of the blanking cavity 10 remains complete and gapless, avoiding the material from splashing to the outside of the blanking cavity 10.

[0068] See Figures 3 to 5, preferably, the first wing portion 21 and the connecting portion 32 are connected by an adjusting structure, and the adjusting structure is used to adjust the rotation angle of the blanking plate 2 and fix the blanking plate 2 to the first baffle 3; the second wing portion 22 and the second baffle 4 may be in parallel abutting connection, or the second wing portion 22 and the second baffle 4 may also be connected by an adjusting structure. When the blanking plate 2 needs to be adjusted, first place the adjusting structure in the unlocked state, then rotate the blanking plate 2 to a suitable position, and then lock the adjusting structure. The adjusting structure generates a holding force between the first wing portion 21 and the connecting portion 32, and between the second wing portion 22 and the second baffle 4, so that the positions of the first wing portion 21 and the connecting portion 32 are relatively fixed, and the positions of the second wing portion 22 and the second baffle 4 are relatively fixed, thereby connecting and fixing the first baffle 3, the second baffle 4 and the two blanking plates 2. The adjusting structures are provided between the first wing portion 21 and the connecting portion 32, and between the second wing portion 22 and the second baffle 4, which is beneficial to improving the stability of the connection between the first baffle 3, the second baffle 4 and the two blanking plates 2 when the adjusting structure is in the locked state.

[0069] See Figures 3 to 5 , preferably, the adjusting structure includes a connecting member 7, a connecting hole 8 and a long hole 9. The connecting hole 8 and the long hole 9 are respectively provided on the first wing portion 21 and the connecting portion 32 or respectively provided on the second wing portion 22 and the second baffle 4. The connecting member 7 connects the connecting hole 8 and the long hole 9, and the position of the connecting member 7 in the long hole 9 is adjustable. For the adjusting structure provided between the first wing portion 21 and the connecting portion 32, a connecting hole 8 can be opened on one of the first wing portion 21 and the connecting portion 32, and a long hole 9 can be opened on the other. For the adjusting structure provided between the second wing portion 22 and the second baffle 4, a connecting hole 8 can be opened on one of the second wing portion 22 and the second baffle 4, and a long hole 9 can be opened on the other.

[0070] In this embodiment, preferably, long holes 9 are opened on both the first wing portion 21 and the second wing portion 22, and connecting holes 8 are opened on the connecting portion 32 and the second baffle 4. Further, the connecting member 7 is a bolt and nut. The bolt passes through the connecting hole 8 and the long hole 9, and the nut is tightened onto the tail end of the bolt protruding. The bolt head and the nut apply a clamping force to the first wing portion 21 and the connecting portion 32 or the second wing portion 22 and the second baffle 4 so that they are relatively fixed to each other.

[0071] Preferably, the shape of the long hole 9 is arc-shaped, and the center of the arc coincides with the rotation center of the blanking plate 2 rotating around the upper end of the blanking plate 2. When adjusting the blanking plate 2, first loosen the nut, then rotate the blanking plate 2, and the bolt rod slides relative to the long hole 9 along an arc trajectory. After adjusting to the appropriate position, tighten the nut again, and the position of the bolt relative to the long hole 9 is fixed. Further, a plurality of long holes 9 are provided on both the first wing portion 21 and the second wing portion 22. The plurality of long holes 9 are spaced from the upper end to the lower end of the blanking plate 2, and the centers of the arcs of the plurality of long holes 9 coincide with the rotation center of the blanking plate 2. Correspondingly, a plurality of connection holes 8 corresponding to the plurality of long holes 9 one by one are provided on both the connecting portion 32 and the second baffle 4. Bolts are inserted through each pair of long holes 9 and connection holes. The arc length along the circumference of the long hole 9 farther from the rotation center of the blanking plate 2 is longer, so as to ensure that all bolts can smoothly slide in the long hole 9 when the blanking plate 2 is rotated.

[0072] See Figures 5 to 7 , preferably, the blanking device of this embodiment further includes a housing 5. The housing 5 is used to be placed above the belt conveyor 03 and form a blanking space 50 between the housing 5 and the belt conveyor 03. The lower end of the blanking housing 1 is connected to the housing 5, and the discharge port 12 is communicated with the blanking space 50. The connection between the lower end of the blanking housing 1 and the housing 5 ensures the sealing between the blanking housing 1 and the housing 5, preventing the material from scattering or splashing during the transfer process. The blanking space 50 is a passage for the material to flow from the discharge port 12 of the blanking housing 1 through the housing 5 to the belt conveyor 03. The discharge port 12 is communicated with the blanking space 50, and the side wall surfaces in the up-and-down direction of the blanking space 50 are all distributed around the discharge port 12. The side wall surfaces of the blanking space 50 surround the blanking port of the blanking space 50 facing the belt conveyor 03. Therefore, when the material flows from the discharge port 12 of the blanking housing 1 into the blanking space 50, the blanking space 50 will not interfere with the fabric distribution of the material when it is output from the discharge port 12, enabling the material to smoothly pass through the blanking space 50 and finally fall on the belt conveyor 03. The housing 5 matches the lateral length of the belt conveyor 03. The lower end of the housing 5 is attached to the belt conveyor 03 and remains relatively fixed to the belt conveyor 03, so that the material can smoothly and as much as possible fall from the blanking port of the blanking space 50 onto the belt conveyor 03, thereby reducing the loss caused by the material splashing to the outside during the falling process.

[0073] See Figures 5 to 7, preferably, the lower end of the first wall surface 13 extends into the blanking space 50. During the process of adjusting the angle of the first wall surface 13 inclined downward into the blanking cavity 10 relative to the second wall surface 14, the lower end of the first wall surface 13 remains inside the blanking space 50. The lower end of the first wall surface 13 extends into the blanking space 50. Even if the angle of the first wall surface 13 inclined downward into the blanking cavity 10 changes, the lower end of the first wall surface 13 still remains inside the blanking space 50, ensuring a continuous sliding path for the material to slide along the first wall surface 13 from the blanking cavity 10 to the blanking space 50, and reducing the risk of the material splashing outside the housing 5 during the falling process from the blanking housing 1 to the housing 5.

[0074] Furthermore, an opening 51 is provided at one end of the housing 5 connected to the blanking housing 1. The lower ends of the first baffle 3 and the second baffle 4 are connected to the outer periphery of the opening 51 of the housing 5. Preferably, the lower ends of the first baffle 3 and the second baffle 4 are both folded outward toward the outside of the blanking cavity 10 to form a connecting plate 100, and are connected to the housing 5 in a fitting manner through the connecting plate 100. The opening 51 is adapted to the discharge port 12, and convex plates 52 extend toward each other along the two opposite sides in the transverse direction of the part of the opening 51 corresponding to the first outlet 121 of the discharge port 12. Gaps are formed between the two opposite sides in the longitudinal direction of the convex plates 52 and the connecting part 32 of the first baffle 3 and the housing 5 respectively. The first wing part 21 and the second wing part 22 on both sides of the blanking plate 2 are respectively inserted into the gaps and extend into the blanking space 50. And when the blanking plate 2 is fixed between the first baffle 3 and the second baffle 4, the convex plates 52 are located between the first wing part 21 and the second wing part 22 to separate the blanking space 50 inside the housing 5 from the outside world above the housing 5, thereby preventing the material that has entered the blanking space 50 from splashing to the outside world between the first wing part 21 and the second wing part 22. Thus, the discharge port 12 formed by the blanking plate 2, the first baffle 3 and the second baffle 4 is closely matched with the opening 51 of the housing 5, avoiding the splashing of the material from the gap between the opening 51 and the discharge port 12 when the discharge port 12 is smaller than the opening 51, and the material falling to the upper end of the housing 5 and being unable to enter the blanking space 50 when the discharge port 12 is larger than the opening 51.

[0075] Preferably, the blanking device of this embodiment further includes a mounting plate 6. The mounting plate 6 is provided at the upper end of the blanking housing 1 and is connected to the outer periphery of the feed inlet 11. By setting a connecting structure on the mounting plate 6 to fix the blanking housing 1 to the in-situ air separation and impurity removal machine 01, it can ensure the accurate docking of the feed inlet 11 with the material output area of the in-situ air separation and impurity removal machine 01, and at the same time improve the sealing performance of the docking between the blanking housing 1 and the in-situ air separation and impurity removal machine 01. When the blanking housing 1 needs to be repeatedly installed and disassembled, setting the connecting structure on the mounting plate 6 can also reduce the wear and damage to the feed inlet 11.

[0076] When the blanking device of this embodiment is installed, the upper end of the blanking shell 1 is fixedly connected to the in-situ air separation and impurity removal machine 01 through the mounting plate 6. The lower end of the blanking shell 1 is connected with a cover shell 5, and the lower end of the cover shell 5 is fitted and connected to the belt conveyor 03.

[0077] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
