Description

Technical Field

[0001] The invention belongs to the technical field of powder collection and filtration, and in particular relates to a grading dust removal device for crushing sticky materials. Background Art

[0002] During the crushing and grinding process, powder materials are mostly transported by airflow, and ultimately need to be screened through multiple stages to distinguish and collect particles and powder in the airflow. In order to simultaneously ensure the efficiency and effectiveness of screening and collecting dust materials in the gas, this solution is divided into three stages to achieve the removal of powder and granular materials. First, a flat screen with large mesh is used to efficiently remove large particles that are not fully ground. Then, a cyclone collection assembly is used to efficiently separate the powder. In order to solve the problem of incomplete dust separation by the cyclone collection assembly, the present invention is further provided with a wavy screen plate at the end. The wavy screen plate with small meshes that has relatively low efficiency but complete separation can achieve complete separation of dust and air. Summary of the Invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a grading dust removal equipment for crushing sticky materials. Although the small-mesh sieve plate has a good separation effect, the powder is light and not easy to fall naturally when pushed by a continuous airflow. Long-term accumulation can easily clog the mesh of the wave-type sieve plate. In order to solve this problem, the present invention proposes a wave-type dust collection assembly and an automatic conveying assembly. Through the wavy design of the wave-type sieve plate, in conjunction with the powder collection tube and conveying auger located below the upper arc portion, the powder intercepted by the wave-type sieve plate can automatically fall into the powder collection tube after losing the airflow push. At the same time, the two sides of the lower arc portion also have the function of guiding the airflow, so that the powder that originally hit the lower arc portion will move to the upper arc portion with the airflow.

[0004] The technical solution adopted by the present invention is as follows: The present invention proposes a grading dust removal equipment for crushing sticky materials, including a wave-type collecting mechanism, a powder separation cylinder, a grading screening mechanism, a rotary wind locking assembly, a first frame and a second frame, the wave-type collecting mechanism is arranged in the powder separation cylinder, the powder separation cylinder is arranged on the first frame, the grading screening mechanism is arranged on the second frame, and the rotary wind locking assembly is arranged below the grading screening mechanism.

[0005] This solution achieves the removal of powder materials in three stages. First, large particles that are not fully ground are efficiently removed through a flat screen with large mesh. Then, the powder is efficiently separated through a cyclone collection component. In order to solve the problem of incomplete dust separation by the cyclone collection component, the present invention is equipped with a wave-type screen plate at the end. The wave-type screen plate with small mesh has low efficiency but complete separation, so as to achieve complete separation of dust and air.

[0006] Furthermore, the wave-type collection mechanism includes a wave-type dust collection component, an automatic conveying component and an airflow dispersion component, wherein the wave-type dust collection component is arranged on the upper part of the powder separation cylinder, the automatic conveying component array is arranged in the wave-type dust collection component, and the airflow dispersion component is arranged in the powder separation cylinder; Preferably, the wave-type dust collection assembly includes a wave-type sieve plate, a powder collection pipe and a collection pipe. The wave-type sieve plate is fixed in the powder separation cylinder. The wave-type sieve plate is alternately provided with upper arc portions and lower arc portions. The powder collection pipe is located below the upper arc portion and there is a gap between the powder collection pipe and the upper arc portion. The part of the powder collection pipe located inside the powder separation cylinder is provided with a half-cut portion. One end of the powder collection pipe is provided with an end plate portion. The collection pipe is fixed to the other end of the powder collection pipe and is connected to the powder collection pipe.

[0007] Through the wavy design of the wavy screen plate, combined with the powder collection tube and conveying auger located below the upper arc part, the powder intercepted by the wavy screen plate can automatically fall into the powder collection tube after losing the push of the airflow; at the same time, the two sides of the lower arc part also have the function of guiding the airflow, so that the powder that originally hit the lower arc part will move to the upper arc part with the airflow.

[0008] As a further preference of the present invention, the automatic conveying assembly includes a hollow auger bracket, a conveying auger and a directional wind wheel, the hollow auger bracket is fixed in the powder collection tube, the conveying auger is rotatably arranged in the hollow auger bracket and the end plate, the directional wind wheel is fixed on the shaft of the conveying auger, and the directional wind wheel is evenly distributed in an annular shape with arc-shaped blades.

[0009] When the directional wind wheel is blown by the air flow, it can drive the conveying auger to rotate in one direction, thereby continuously conveying the powder material falling into the powder collection pipe toward the manifold, thereby achieving the purpose of continuous cleaning.

[0010] As a further preferred embodiment of the present invention, the air flow dispersion assembly includes a conveying pipe 1, a diffusion hopper and a dispersion shaft, the conveying pipe 1 is arranged below the diffusion hopper, the diffusion hopper is fixed to the inside of the powder separation cylinder, the dispersion shaft is rotatably arranged in the conveying pipe 1 and the diffusion hopper, and a dispersion impeller is provided on the dispersion shaft.

[0011] When the airflow passes through the dispersion impeller, it can drive the dispersion impeller to rotate. While the dispersion impeller rotates, it can also disperse the airflow in the conveying pipe, making it move upward in a nearly vertical direction.

[0012] Furthermore, the powder separation cylinder is fixedly connected to the first frame, and an exhaust port is provided above the wave-type screen plate of the powder separation cylinder. A top cover and a bottom cover are respectively provided at both ends of the powder separation cylinder.

[0013] Furthermore, the grading and screening mechanism includes a cyclone collecting component and a particle screening component, and the cyclone collecting component and the particle screening component are both arranged on the second frame, and the cyclone collecting component and the particle screening component are arranged side by side.

[0014] Preferably, the cyclone collection assembly includes a cyclone collection shell and a second conveying pipe. The cyclone collection shell is arranged on the second frame, and a top cover second is provided on the cyclone collection shell. The first conveying pipe is arranged between the diffusion bucket and the top cover second. The cyclone collection shell is also provided with an offset air inlet, and the second conveying pipe is arranged on the offset air inlet.

[0015] The airflow carrying powder enters the cyclone collection housing from the offset air inlet and can spiral downward along the inner wall of the cyclone collection housing. The powder diffuses outward under the action of centrifugal force, loses kinetic energy and falls after hitting the inner wall of the cyclone collection housing, and then falls through the air lock chamber; after reaching the bottom, the airflow will move upward from the center of the cyclone collection housing and enter the conveying pipe.

[0016] As a further preferred embodiment of the present invention, the particle screening assembly includes a conveying pipe three, a flat screen and a particle screening cylinder, the particle screening cylinder is arranged on the second frame, the particle screening cylinder is provided with a top cover three, the conveying pipe two is arranged between the offset air inlet and the top cover three, the flat screen is arranged in the particle screening cylinder, and one end of the conveying pipe three extends into the particle screening cylinder and is located below the flat screen.

[0017] The large-mesh flat screen allows fully ground powder to pass through and intercepts incompletely ground particles. Due to the large mesh size of the flat screen, the filtration efficiency is significantly higher than that of the wave-type screen. At the same time, since the particles fall naturally after hitting the flat screen, they will not cause blockage of the flat screen.

[0018] Furthermore, the rotary wind-locking components are provided with two groups, and the two groups of rotary wind-locking components are respectively arranged below the cyclone collecting shell and the particle screening cylinder.

[0019] Preferably, the rotary air lock assembly includes an air lock chamber, a rotary impeller and a rotary motor. The air lock chamber is arranged at the bottom of the cyclone collection shell and the particle screening cylinder, the rotary motor is arranged on the side of the air lock chamber, the rotary impeller is arranged on the output shaft of the rotary motor, and the rotary impeller rotates in the air lock chamber.

[0020] The continuously and slowly rotating impeller can form a closed space, which can not only prevent the flow of gas, but also discharge the materials accumulated in the rotary air lock component.

[0021] The beneficial effects achieved by the present invention using the above structure are as follows: (1) This solution achieves powder material removal in three stages. First, large particles that are not fully ground are efficiently removed through a flat screen with large mesh. Then, the powder is efficiently separated through a cyclone collection assembly. In order to solve the problem of incomplete dust separation by the cyclone collection assembly, the present invention sets a wave-type screen plate at the end. The wave-type screen plate with small mesh has low efficiency but complete separation, so as to achieve complete separation of dust and air.

[0022] (2) Through the wavy design of the wave-shaped screen plate, combined with the powder collection tube and conveying auger located below the upper arc part, the powder intercepted by the wave-shaped screen plate can automatically fall into the powder collection tube after losing the airflow push; at the same time, the two sides of the lower arc part also have the function of guiding the airflow, so that the powder that originally hit the lower arc part will move to the upper arc part with the airflow.

[0023] (3) When the directional wind wheel is blown by the air flow, it can drive the conveying auger to rotate in one direction, thereby continuously conveying the powder material falling in the powder collection pipe toward the manifold, thereby achieving the purpose of continuous cleaning.

[0024] (4) When the airflow passes through the dispersion impeller, it can drive the dispersion impeller to rotate. While the dispersion impeller rotates, it can also disperse the airflow in the conveying pipe, causing it to move upward in a nearly vertical direction.

[0025] (5) The airflow carrying powder enters the cyclone collection housing from the offset air inlet and spirals downward along the inner wall of the cyclone collection housing. The powder diffuses outward under the action of centrifugal force, loses kinetic energy and falls after hitting the inner wall of the cyclone collection housing, and then falls through the air lock chamber; after reaching the bottom, the airflow moves upward from the center of the cyclone collection housing and enters the conveying pipe.

[0026] (6) The large-mesh flat screen allows fully ground powder to pass through and intercepts insufficiently ground particles. Since the mesh of the flat screen is large, the filtration efficiency is significantly higher than that of the wave-type screen. At the same time, since the particles will fall naturally after hitting the flat screen, they will not cause blockage of the flat screen.

[0027] (7) The continuously and slowly rotating impeller can form a closed space, which can not only prevent the flow of gas, but also discharge the materials accumulated in the rotary air lock component. BRIEF DESCRIPTION OF THE DRAWINGS

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0033] like Figures 1 to 8 As shown, the present invention proposes a grading dust removal device for crushing sticky materials, comprising a wave-type collecting mechanism 1, a powder separation cylinder 2, a grading screening mechanism 3, a rotary air lock assembly 4, a first frame 5, and a second frame 6. The wave-type collecting mechanism 1 is arranged in the powder separation cylinder 2, the powder separation cylinder 2 is arranged on the first frame 5, the grading screening mechanism 3 is arranged on the second frame 6, and the rotary air lock assembly 4 is arranged below the grading screening mechanism 3. This solution achieves the removal of powder materials in three stages. First, large particles that are not fully ground are efficiently removed through a flat screen 30 with large meshes. Then, the powder is efficiently separated through a cyclone collection component 25. In order to solve the problem of incomplete dust separation by the cyclone collection component 25, the present invention is further provided with a wave-type screen plate 10 at the end. The wave-type screen plate 10 with small meshes has low efficiency but complete separation, thereby achieving complete separation of dust and air.

[0034] The wave-type collection mechanism 1 includes a wave-type dust collection component 7, an automatic conveying component 8, and an airflow dispersion component 9. The wave-type dust collection component 7 is arranged on the upper part of the powder separation cylinder 2, the automatic conveying component 8 is arranged in an array in the wave-type dust collection component 7, and the airflow dispersion component 9 is arranged in the powder separation cylinder 2; The wave-type dust collection assembly 7 includes a wave-type sieve plate 10, a powder collection pipe 11 and a manifold 12. The wave-type sieve plate 10 is fixed in the powder separation cylinder 2. The wave-type sieve plate 10 is alternately provided with upper arc portions 20 and lower arc portions 21. The powder collection pipe 11 is located below the upper arc portion 20 and there is a gap between the powder collection pipe 11 and the upper arc portion 20. The part of the powder collection pipe 11 located inside the powder separation cylinder 2 is provided with a half-cut portion 22. One end of the powder collection pipe 11 is provided with an end plate portion 23. The manifold 12 is fixed to the other end of the powder collection pipe 11 and is communicated with the powder collection pipe 11.

[0035] Through the wavy design of the wavy screen plate 10, in conjunction with the powder collection tube 11 and the conveying auger 14 located below the upper arc portion 20, the powder intercepted by the wavy screen plate 10 can automatically fall into the powder collection tube 11 after losing the push of the airflow; at the same time, the two sides of the lower arc portion 21 also have the function of guiding the airflow, so that the powder originally hitting the lower arc portion 21 will move to the upper arc portion 20 with the airflow.

[0036] The automatic conveying component 8 includes a hollow auger bracket 13, a conveying auger 14 and a directional wind wheel 15. The hollow auger bracket 13 is fixedly connected to the powder collection tube 11. The conveying auger 14 is rotatably arranged between the hollow auger bracket 13 and the end plate 23. The directional wind wheel 15 is fixedly connected to the shaft of the conveying auger 14. The directional wind wheel 15 is evenly distributed with arc blades 24 in a ring.

[0037] When blown by the airflow, the directional wind wheel 15 can drive the conveying auger 14 to rotate in one direction, thereby continuously conveying the powder material falling into the powder collection pipe 11 toward the manifold 12, thereby achieving the purpose of continuous cleaning.

[0038] The air flow dispersion assembly 9 includes a conveying pipe 16, a diffusion hopper 17 and a dispersion shaft 18. The conveying pipe 16 is arranged below the diffusion hopper 17. The diffusion hopper 17 is fixed to the inside of the powder separation cylinder 2. The dispersion shaft 18 is rotatably arranged in the conveying pipe 16 and the diffusion hopper 17. A dispersion impeller 19 is provided on the dispersion shaft 18.

[0039] When the airflow passes through the dispersion impeller 19, it can drive the dispersion impeller 19 to rotate. While the dispersion impeller 19 rotates, it can also disperse the airflow in the conveying pipe 16, causing it to move upward in a nearly vertical direction.

[0040] The powder separation cylinder 2 is fixed to the first frame 5. The powder separation cylinder 2 is provided with an exhaust port 38 above the wave-type screen plate 10. The two ends of the powder separation cylinder 2 are respectively provided with a top cover 39 and a bottom cover 40.

[0041] The grading and screening mechanism 3 includes a cyclone collecting assembly 25 and a particle screening assembly 26 . The cyclone collecting assembly 25 and the particle screening assembly 26 are both arranged on the second frame 6 , and the cyclone collecting assembly 25 and the particle screening assembly 26 are arranged side by side.

[0042] The cyclone collection assembly 25 includes a cyclone collection shell 27 and a conveying pipe 28. The cyclone collection shell 27 is arranged on the second frame 6. The cyclone collection shell 27 is provided with a top cover 2 34. The conveying pipe 16 is arranged between the diffusion bucket 17 and the top cover 2 34. The cyclone collection shell 27 is also provided with an offset air inlet 32. The conveying pipe 28 is arranged on the offset air inlet 32.

[0043] The airflow carrying powder enters the cyclone collecting housing 27 from the offset air inlet 32, and can spiral downward along the inner wall of the cyclone collecting housing 27. The powder diffuses outward under the action of centrifugal force, loses kinetic energy and falls after hitting the inner wall of the cyclone collecting housing 27, and then falls through the air lock chamber 35; after reaching the bottom, the airflow will move upward from the center position of the cyclone collecting housing 27 and enter the conveying pipe 16.

[0044] The particle screening assembly 26 includes a conveying pipe three 29, a flat screen 30 and a particle screening cylinder 31. The particle screening cylinder 31 is arranged on the second frame 6. The particle screening cylinder 31 is provided with a top cover three 33. The conveying pipe two 28 is arranged between the offset air inlet 32 ​​and the top cover three 33. The flat screen 30 is arranged in the particle screening cylinder 31. One end of the conveying pipe three 29 extends into the particle screening cylinder 31 and is located below the flat screen 30.

[0045] The large-mesh flat screen 30 allows fully ground powder to pass through and intercepts insufficiently ground particles. Since the mesh of the flat screen 30 is large, the filtration efficiency is significantly higher than that of the wave-type screen plate 10. At the same time, since the particles will naturally fall after hitting the flat screen 30, they will not cause blockage to the flat screen 30.

[0046] There are two groups of rotary air-locking components 4 , which are respectively arranged below the cyclone collecting housing 27 and the particle screening cylinder 31 .

[0047] The rotary air lock assembly 4 includes an air lock chamber 35, a rotary impeller 36 and a rotary motor 37. The air lock chamber 35 is arranged at the bottom of the cyclone collection shell 27 and the particle screening cylinder 31, the rotary motor 37 is arranged on the side of the air lock chamber 35, the rotary impeller 36 is arranged on the output shaft of the rotary motor 37, and the rotary impeller 36 rotates in the air lock chamber 35.

[0048] The continuously and slowly rotating rotary impeller 36 can form a closed space, which can not only prevent the flow of gas, but also discharge the materials accumulated in the rotary air-locking component 4.

[0049] like Figure 9 As shown, the arrows indicate the flow direction of the gas. After the gas in the delivery pipe 16 reaches the diffusion hopper 17, it can drive the dispersion impeller 19 to rotate, thereby diffusing the originally concentrated airflow toward all sides, causing it to move upward at a nearly vertical angle. After the powder in the airflow hits the lower arc portion 21 or the powder collecting tube 11, it will slide along the lower arc portion 21 or the powder collecting tube 11 toward the upper arc portion 20 under the continuous push of the subsequent airflow. When it reaches the upper arc portion 20, the powder will fall into the powder collecting tube 11 due to the obstruction of the powder collecting tube 11 and is no longer pushed by the airflow.

[0050] During specific use, the ground material is conveyed by the airflow through the conveying pipe 3 29 and enters the particle screening drum 31. The materials that can be carried by the airflow are mainly powder or small particles. The airflow and powder can pass through the flat screen 30 and enter the cyclone collection housing 27 through the conveying pipe 2 28, while the particles cannot pass through the flat screen 30. At the same time, due to the large weight of the particles, even if there is continued airflow, the particles will fall and be discharged to the outside through the rotary air lock component 4. Since the mesh of the flat screen 30 is relatively large, the blocking ability to the airflow and powder is relatively low, and thus the screening efficiency is relatively high.

[0051] After the airflow, carrying powder, enters the cyclone collection housing 27 through the offset air inlet 32, it spirals downward along the inner wall of the cyclone collection housing 27, forming a descending, outward-spinning dust-laden airflow. The centrifugal force generated during the intense rotation throws the dust particles, which have a much greater density than the gas, toward the inner wall of the cyclone collection housing 27. Once the dust particles come into contact with the wall, they lose their inertia and fall down along the wall by their own gravity into the air lock chamber 35. After reaching the bottom of the cyclone collecting housing 27 , the rotating downward airflow turns upward along the axis of the cyclone collecting housing 27 to form an ascending inward rotating airflow and is discharged from the delivery pipe 16 .

[0052] Due to the separation of the rotary impeller 36, the air flow cannot flow freely through the rotary air lock component 4; however, when the rotary impeller 36 rotates, the material falling on the rotary impeller 36 can be transferred to the outside and discharged.

[0053] The powder collection efficiency of the cyclone collection assembly 25 is high but not complete, and a small amount of powder is still contained in the airflow entering the conveying pipe 16. When the airflow reaches the diffusion hopper 17, it first drives the dispersion impeller 19 to rotate, and then disperses outward under the stirring of the dispersion impeller 19, so that the airflow can move upward in a nearly vertical direction. After the powder in the airflow hits the lower arc portion 21 or the powder collecting tube 11, it will slide along the lower arc portion 21 or the powder collecting tube 11 toward the upper arc portion 20 under the continuous push of the subsequent airflow. When it reaches the upper arc portion 20, the powder will fall into the powder collecting tube 11 due to the obstruction of the powder collecting tube 11 and is no longer pushed by the airflow.

[0054] When blown by the airflow, the directional wind wheel 15 can drive the conveying auger 14 to rotate in one direction, thereby continuously conveying the powder material falling into the powder collection pipe 11 toward the manifold 12, thereby achieving the purpose of continuous cleaning.

[0055] Although the small-mesh wave-type sieve plate 10 has a good separation effect, the powder is light and is not easy to fall naturally when subjected to the continuous airflow force. It is easy to clog the mesh of the wave-type sieve plate 10 when accumulated for a long time. The above problem can be solved by collecting the powder through the powder collection pipe 11.
