Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of powder collection and filtration, and particularly relates to a grading dust removal equipment for crushing viscous materials. BACKGROUND

[0002] In the process of crushing and grinding, powder materials are usually transported by airflow, and finally need to be distinguished and collected by multi-stage screening. In order to ensure the efficiency and effect of screening and collecting dust in the gas, the present application removes powder and granular materials in three stages. First, large particles that are not fully ground are removed efficiently by a flat screen with large mesh holes. Then, the powder is separated efficiently by a cyclone collection assembly. In order to solve the problem that the cyclone collection assembly does not completely separate the dust, the present application further provides a wave-shaped sieve plate. The wave-shaped sieve plate with small mesh holes has low efficiency but complete separation, thereby achieving complete separation of dust and air. SUMMARY

[0003] In view of the above problems, the present application provides a grading dust removal equipment for crushing viscous materials. Although the wave-shaped sieve plate has good separation effect, the powder is light and is not easy to fall naturally when subjected to continuous airflow. Long-term accumulation can easily block the mesh holes of the wave-shaped sieve plate. In order to solve this problem, the present application provides a wave-shaped dust removal and collection assembly and an automatic conveying assembly. The wave-shaped design of the wave-shaped sieve plate, together with the powder collection pipe and conveying auger located below the upper arc portion, can make the powder intercepted by the wave-shaped sieve plate fall into the powder collection pipe automatically after losing the airflow driving. Meanwhile, the lower arc portion has the function of guiding the airflow, so that the powder originally hitting the lower arc portion will move to the upper arc portion along with the airflow.

[0004] The technical scheme adopted by the present application is as follows: the present application provides a grading dust removal equipment for crushing viscous materials, which comprises a wave-shaped collection mechanism, a powder separation cylinder, a grading screening mechanism, a rotary wind locking assembly, a first rack and a second rack.

[0005] The present application removes powder materials in three stages. First, large particles that are not fully ground are removed efficiently by a flat screen with large mesh holes. Then, the powder is separated efficiently by a cyclone collection assembly. In order to solve the problem that the cyclone collection assembly does not completely separate the dust, the present application further provides a wave-shaped sieve plate.

[0008] Through the wave type design of the wave type sieve plate, the powder intercepted by the wave type sieve plate can automatically fall into the powder collecting pipe after losing the airflow driving force in cooperation with the powder collecting pipe located below the upper arc portions and the conveying auger.

[0010] When the directional wind wheel is blown by the airflow, the conveying auger can be driven to rotate in one direction, so as to continuously convey the powder material falling into the powder collecting pipe towards the converging pipe, thereby achieving the purpose of continuous cleaning.

[0011] Further preferably, the airflow dispersing assembly comprises a conveying pipe one, a diffusion hopper and a dispersing shaft, the conveying pipe one is arranged below the diffusion hopper, the diffusion hopper is fixedly connected to the inside of the powder separating cylinder, the dispersing shaft is rotatably arranged in the conveying pipe one and the diffusion hopper, and the dispersing shaft is provided with a dispersing impeller.

[0012] The airflow can drive the dispersing impeller to rotate when passing through the dispersing impeller, and the dispersing impeller can disperse the airflow in the conveying pipe one while rotating, so as to move upwards in a nearly vertical direction.

[0013] Further, the powder separating cylinder is fixedly connected to the first rack, the powder separating cylinder is provided with an exhaust port above the wave type sieve plate, and the powder separating cylinder is respectively provided with a top cover one and a bottom cover at both ends.

[0014] Further, the grading and screening mechanism comprises a cyclone collecting assembly and a particle screening assembly, both of which are arranged on the second frame and are arranged side by side.

[0015] Preferably, the cyclone collecting assembly comprises two cyclone collecting housings and two conveying pipes, the two cyclone collecting housings are arranged on the second frame, and two top covers are arranged on the two cyclone collecting housings, the first conveying pipe is arranged between the diffusion hopper and the two top covers, and the second conveying pipe is arranged on the biasing air inlet of the cyclone collecting housing.

[0016] The airflow carrying the powder enters the cyclone collecting housing from the biasing air inlet, spirals downward along the inner wall of the cyclone collecting housing, and the powder spreads outward under the action of centrifugal force, loses kinetic energy after impacting the inner wall of the cyclone collecting housing, and then falls through the air locking chamber; after the airflow reaches the bottom, it moves upward from the center of the cyclone collecting housing and enters the first conveying pipe.

[0017] Further preferably, the particle screening assembly comprises a third conveying pipe, a flat screen and a particle screening cylinder, the particle screening cylinder is arranged on the second frame, a third top cover is arranged on the particle screening cylinder, the second conveying pipe is arranged between the biasing air inlet and the third top cover, the flat screen is arranged in the particle screening cylinder, and one end of the third conveying pipe extends into the particle screening cylinder and is located below the flat screen.

[0018] The flat screen with large mesh holes can allow the fully ground powder to pass through and intercept the insufficiently ground particles; since the mesh holes of the flat screen are large, the filtering efficiency is significantly higher than that of the wavy screen plate; at the same time, since the particles naturally fall after impacting the flat screen, the flat screen is not blocked.

[0019] Further, the rotary air locking assembly is provided in two groups, and the two groups of rotary air locking assemblies are arranged below the cyclone collecting housing and the particle screening cylinder, respectively.

[0020] Preferably, the rotary air locking assembly comprises an air locking chamber, a rotary impeller and a rotary motor, the air locking chamber is arranged at the bottom of the cyclone collecting housing and the particle screening cylinder, the rotary motor is arranged on the side of the air locking chamber, the rotary impeller is arranged on the output shaft of the rotary motor, and the rotary impeller rotates in the air locking chamber.

[0021] The continuously and slowly rotating rotary 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 locking assembly.

[0022] The beneficial effects achieved by the present application with the above structure are as follows:

[0023] (1) This scheme achieves powder material removal in three stages. First, large particles that are not fully ground are efficiently removed by a flat screen with large mesh. Then, the powder is efficiently separated by a cyclone collection component. In order to solve the problem of incomplete dust separation by the cyclone collection component, the present invention sets a wave-shaped screen plate at the end. The wave-shaped screen plate with small mesh is less efficient but achieves thorough separation of dust and air.

[0024] (2) Through the wave-shaped design of the wave-shaped sieve plate, combined with the powder collection pipe and conveying auger located below the upper arc, the powder intercepted by the wave-shaped sieve plate can automatically fall into the powder collection pipe after losing the airflow push; at the same time, the two sides of the lower arc also have the function of guiding the airflow, so that the powder that originally hit the lower arc will move to the upper arc with the airflow.

[0025] (3) When the directional fan is blown by the airflow, it can drive the conveying auger to rotate in one direction, thereby continuously conveying the powder material that falls into the powder collection pipe toward the manifold, thus achieving the purpose of continuous cleaning.

[0026] (4) When the airflow passes through the dispersing impeller, it can drive the dispersing impeller to rotate. While the dispersing impeller rotates, it can also disperse the airflow in the conveying pipe, causing it to move upward in a nearly vertical direction.

[0027] (5) The airflow carrying the powder enters the cyclone collection shell from the offset air inlet and spirals downward along the inner wall of the cyclone collection shell. The powder diffuses outward under the action of centrifugal force. After hitting the inner wall of the cyclone collection shell, it loses kinetic energy and falls down, and then falls through the air lock chamber. After the airflow reaches the bottom, it will move upward from the center of the cyclone collection shell and enter the conveying pipe.

[0028] (6) The large mesh size of the flat screen allows fully ground powder to pass through and intercepts unground particles; because the mesh size of the flat screen is large, the filtration efficiency is significantly higher than that of the corrugated screen; at the same time, since the particles fall naturally after impacting the flat screen, they will not cause blockage to the flat screen.

[0029] (7) The continuously and slowly rotating impeller can form a closed space, which can not only prevent gas flow, but also discharge the material accumulated in the rotary airlock assembly. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0043] like Figures 1-8 As shown, the present invention proposes a grading and dust removal device for crushing viscous materials, including a wave-type collection mechanism 1, a powder separation cylinder 2, a grading and screening mechanism 3, a rotary airlock assembly 4, a first frame 5, and a second frame 6. The wave-type collection mechanism 1 is disposed in the powder separation cylinder 2, the powder separation cylinder 2 is disposed on the first frame 5, the grading and screening mechanism 3 is disposed on the second frame 6, and the rotary airlock assembly 4 is disposed below the grading and screening mechanism 3.

[0044] This solution achieves powder material removal in three stages. First, large particles that are not fully ground are efficiently removed by a flat screen 30 with large mesh. Then, the powder is efficiently separated by a cyclone collection component 25. To solve the problem of incomplete dust separation by the cyclone collection component 25, a corrugated screen plate 10 is added at the end. The corrugated screen plate 10 with small mesh, which has lower efficiency but more thorough separation, achieves complete separation of dust and air.

[0045] 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 located at the top of the powder separation cylinder 2, the automatic conveying component 8 is arrayed in the wave-type dust collection component 7, and the airflow dispersion component 9 is located in the powder separation cylinder 2.

[0046] 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. An upper arc portion 20 and a lower arc portion 21 are alternately arranged on the wave-type sieve plate 10. The powder collection pipe 11 is located below the upper arc portion 20 and there is a gap between it 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 communicates with the powder collection pipe 11.

[0047] The wave-shaped design of the wave-shaped sieve plate 10, combined with the powder collection pipe 11 and the conveying auger 14 located below the upper arc portion 20, allows the powder intercepted by the wave-shaped sieve plate 10 to automatically fall into the powder collection pipe 11 after losing the airflow propulsion; 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 that originally hit the lower arc portion 21 will move to the upper arc portion 20 with the airflow.

[0048] The automatic conveying assembly 8 includes a hollow auger support 13, a conveying auger 14, and a directional impeller 15. The hollow auger support 13 is fixedly connected to the powder collection pipe 11. The conveying auger 14 is rotatably disposed in the hollow auger support 13 and the end plate 23. The directional impeller 15 is fixedly connected to the shaft of the conveying auger 14. Arc-shaped blades 24 are evenly distributed in a ring on the directional impeller 15.

[0049] When the directional impeller 15 is blown by the airflow, it can drive the conveying auger 14 to rotate in one direction, thereby continuously conveying the powder material that falls into the powder collection pipe 11 toward the manifold 12, thus achieving the purpose of continuous cleaning.

[0050] The airflow dispersion assembly 9 includes a conveying pipe 16, a diffusion hopper 17, and a dispersion shaft 18. The conveying pipe 16 is located below the diffusion hopper 17, which is fixed inside the powder separation cylinder 2. The dispersion shaft 18 is rotatably disposed in the conveying pipe 16 and the diffusion hopper 17, and a dispersion impeller 19 is provided on the dispersion shaft 18.

[0051] When the airflow passes through the dispersing impeller 19, it can drive the dispersing impeller 19 to rotate. While the dispersing impeller 19 rotates, it can also disperse the airflow in the delivery pipe 16, causing it to move upward in a nearly vertical direction.

[0052] The powder separation cylinder 2 is fixed to the first frame 5. The powder separation cylinder 2 has an exhaust port 38 above the corrugated sieve plate 10. The powder separation cylinder 2 has a top cover 39 and a bottom cover 40 at both ends.

[0053] The grading and screening mechanism 3 includes a cyclone collection component 25 and a particle screening component 26. Both the cyclone collection component 25 and the particle screening component 26 are mounted on the second frame 6 and are arranged side by side.

[0054] The cyclone collection assembly 25 includes a cyclone collection shell 27 and a second conveying pipe 28. The cyclone collection shell 27 is mounted on the second frame 6. The cyclone collection shell 27 is provided with a second top cover 34. The first conveying pipe 16 is located between the diffusion hopper 17 and the second top cover 34. The cyclone collection shell 27 is also provided with an offset air inlet 32. The second conveying pipe 28 is located on the offset air inlet 32.

[0055] The airflow carrying the powder enters the cyclone collection housing 27 through the biased air inlet 32 ​​and spirals downward along the inner wall of the cyclone collection 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 collection housing 27, and then falls through the airlock chamber 35. After the airflow reaches the bottom, it moves upward from the center of the cyclone collection housing 27 and enters the delivery pipe 16.

[0056] The particle screening assembly 26 includes a conveying pipe 29, a flat screen 30, and a particle screening cylinder 31. The particle screening cylinder 31 is mounted on the second frame 6 and has a top cover 33. The conveying pipe 28 is located between the offset air inlet 32 ​​and the top cover 33. The flat screen 30 is located in the particle screening cylinder 31, and one end of the conveying pipe 29 extends into the particle screening cylinder 31 and is located below the flat screen 30.

[0057] The large-mesh flat screen 30 allows fully ground powder to pass through while intercepting insufficiently ground particles; due to the larger mesh size of the flat screen 30, the filtration efficiency is significantly higher than that of the corrugated screen plate 10; at the same time, since the particles fall naturally after impacting the flat screen 30, they will not cause blockage to the flat screen 30.

[0058] Two sets of rotary airlock components 4 are provided, and the two sets of rotary airlock components 4 are respectively located below the cyclone collection shell 27 and the particle screening cylinder 31.

[0059] The rotary airlock assembly 4 includes an airlock chamber 35, a rotary impeller 36, and a rotary motor 37. The airlock chamber 35 is located at the bottom of the cyclone collection shell 27 and the particle screening cylinder 31. The rotary motor 37 is located on the side of the airlock chamber 35. The rotary impeller 36 is located on the output shaft of the rotary motor 37 and is rotatably located in the airlock chamber 35.

[0060] The continuously and slowly rotating impeller 36 can form a closed space, which can both prevent gas flow and discharge the material accumulated in the rotary airlock assembly 4.

[0061] likeFigure 9 As shown, the arrow indicates the direction of gas flow. After the gas in the delivery pipe 16 reaches the diffusion bucket 17, it can drive the dispersing impeller 19 to rotate, thereby diffusing the originally concentrated airflow in all directions and making it move upward at a near-vertical angle.

[0062] After the powder impacts the lower arc portion 21 or the powder collection tube 11 in the airflow, it will slide along the lower arc portion 21 or the powder collection tube 11 toward the upper arc portion 20 under the continuous push of the subsequent airflow. When it reaches the upper arc portion 20, it will fall into the powder collection tube 11 because it is no longer pushed by the airflow due to the obstruction of the powder collection tube 11.

[0063] In practical use, the ground material is transported by airflow through the conveying pipe 29 into the particle screening cylinder 31. The material that can be carried and transported by the airflow is mainly powder or small particle material. The airflow and powder can pass through the flat screen 30 and enter the cyclone collection shell 27 through the conveying pipe 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 a continuous airflow, the particles will fall and be discharged to the outside through the rotary airlock assembly 4.

[0064] Because the mesh size of the flat sieve 30 is relatively large, it has a low barrier to airflow and powder, resulting in high sieving efficiency.

[0065] After the airflow carrying the powder enters the cyclone collection shell 27 through the offset air inlet 32, it can spiral downward along the inner wall of the cyclone collection shell 27 to form a descending outer swirling dust-laden airflow. The centrifugal force generated during the intense rotation throws the dust particles, which are much denser than the gas, toward the inner wall of the cyclone collection shell 27. Once the dust particles come into contact with the wall, they lose their inertial force and fall down along the wall by their own gravity into the airlock chamber 35.

[0066] After reaching the bottom of the cyclone collector housing 27, the rotating and descending airflow turns upward along the axis of the cyclone collector housing 27, forming an upward internal swirling airflow, which is then discharged through the delivery pipe 16.

[0067] Due to the separation of the rotary impeller 36, the airflow cannot flow freely through the rotary airlock assembly 4; however, when the rotary impeller 36 rotates, the material falling on the rotary impeller 36 can be transferred to the outside and discharged.

[0068] The cyclone collecting component 25 has high powder collection efficiency but is not thorough. The airflow entering the conveying pipe 16 still contains a small amount of powder. When the airflow reaches the diffuser 17, it will first drive the dispersing impeller 19 to rotate and disperse outward under the agitation of the dispersing impeller 19, so that the airflow can move upward in a nearly vertical direction.

[0069] After the powder impacts the lower arc portion 21 or the powder collection tube 11 in the airflow, it will slide along the lower arc portion 21 or the powder collection tube 11 toward the upper arc portion 20 under the continuous push of the subsequent airflow. When it reaches the upper arc portion 20, it will fall into the powder collection tube 11 because it is no longer pushed by the airflow due to the obstruction of the powder collection tube 11.

[0070] When the directional impeller 15 is blown by the airflow, it can drive the conveying auger 14 to rotate in one direction, thereby continuously conveying the powder material that falls into the powder collection pipe 11 toward the manifold 12, thus achieving the purpose of continuous cleaning.

[0071] Although the corrugated sieve plate 10 with small mesh has a good separation effect, the powder is light and does not fall naturally when subjected to continuous airflow. When it accumulates for a long time, it is easy to clog the mesh of the corrugated sieve plate 10. The above problem can be solved by collecting the powder through the powder collection pipe 11.
