Description

Technical Field

[0001] This invention relates to the field of solid waste resource utilization and building material processing technology, and in particular to a solid waste-based ceramic tile adhesive raw material sorting, impurity removal and crushing equipment. Background Technology

[0002] Tile adhesive is a special bonding material used for tile bonding in the building decoration field. It can be produced from industrial solid waste such as construction waste and ceramic waste, which can significantly reduce production costs. However, solid waste raw materials often contain metal impurities, large pieces of concrete, sand and gravel, etc., with large differences in particle size distribution and uneven material. Direct use will seriously affect the bonding performance and construction stability of tile adhesive.

[0003] Currently, for the screening and processing of solid waste-based ceramic tile adhesive raw materials, existing technologies mostly employ simple plate screening or air screening processes. Plate screening suffers from problems such as easy material accumulation, low screening efficiency, and easy clogging of screen holes; traditional air screening can only blow on one side of a single feed, resulting in poor material dispersion and inability to achieve accurate grading and sufficient separation of coarse and fine particles.

[0004] In the prior art, patent CN115140351B discloses a ceramic tile adhesive powder screening and recycling device, including a screening box, a reciprocating screen plate, a vibrating motor, and a pneumatic conveying assembly. The adhesive powder is screened through the reciprocating motion of the screen plate, and the screened material is then conveyed to the feeding mechanism by a blower. However, although this technology solves some of the original problems, there are still aspects that need further optimization to better meet actual screening and impurity removal requirements.

[0005] Although the above-mentioned existing technology uses reciprocating screen plates for screening, the material is still prone to continuously accumulating on the screen plate. When the material layer is too thick, the screening efficiency drops significantly and the screen holes are easily blocked. It relies solely on passive screening through the screen holes and cannot effectively remove the usable fine powder attached to the outside of large particles, resulting in low raw material utilization.

[0006] Even if the large particles separated by screening are taken out separately for air screening, they will still be affected by the inherent defects of uneven force of the unilateral wind field and the inability of the material to be fully suspended and dispersed. Not only is the screening efficiency low and the fine powder stripping effect poor, but if reciprocating blowing is to be achieved, a complex reciprocating feeding device needs to be added, which has the problems of cumbersome structure and high operating cost. Furthermore, it is impossible to achieve the classification and screening of mixed materials of different materials.

[0007] Therefore, based on the above analysis, there is still room for improvement in the existing screening and impurity removal equipment for solid waste-based ceramic tile adhesive raw materials. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides a solid waste-based ceramic tile adhesive solid waste raw material sorting, impurity removal, and crushing device, comprising a sorting frame and a crushing device. The top of the sorting frame is provided with a feed inlet, and the sorting frame is connected to the bottom discharge end of the crushing device through the feed inlet. The sorting frame has rectangular openings around its perimeter, and a sieve plate is installed inside the openings for the raw materials to pass through.

[0009] Sliding frames are installed around the sorting frame, and air screening assemblies, including fan blades, are installed inside the sliding frames.

[0010] The air-screening components drive their respective fan blades to rotate sequentially, screening out the raw materials that meet the size requirements from the corresponding side screen plate within the sorting box.

[0011] A discharge frame is installed through the bottom of the sorting frame, and a support component is installed inside the discharge frame. The top of the support component extends into the sorting frame to support the raw materials.

[0012] Preferably, the air screen assembly further includes an air guide shroud slidably installed in the sliding frame, with a rotating shaft inserted into the middle of the air guide shroud and fan blades installed on the outside of the rotating shaft.

[0013] Preferably, the bottom of the air guide shroud has a through groove, and the bottom of the sliding frame has a transverse groove corresponding to the through groove.

[0014] Preferably, the support assembly includes a support plate installed in the discharge frame, an electric push rod is installed on the top of the support plate, the telescopic end of the electric push rod extends into the sorting frame and a support plate is installed thereby by hinge, and the periphery of the support plate corresponds to the inner side of the sorting frame.

[0015] A torsion spring is installed at the hinge.

[0016] Preferably, the discharge frame has grooves around its perimeter, and a bent plate corresponding to the bottom of the support plate is installed in one of the grooves.

[0017] Preferably, the top of the sliding frame and the sorting frame are jointly equipped with a pushing component for driving the air guide shrouds to move respectively. The pushing component includes a pushing groove opened on the top of the sliding frame, and a bent driven plate is installed on the top of each air guide shroud.

[0018] A drive ring is rotatably mounted on the outside of the feed inlet, and an abutment plate is mounted on the outside of the drive ring. The end of the abutment plate corresponding to the driven plate is arc-shaped.

[0019] Preferably, a reset plate is fixedly installed inside the sliding frame, and a reset push rod is installed on one side of the reset plate. The telescopic end of the reset push rod is connected to one side of the air guide shroud.

[0020] Preferably, the bottom of the sliding frame is equipped with a discharge component that supplies airflow to the air screen assembly and receives the raw material after screening. The discharge component includes a rectangular cover installed at the bottom of the sliding frame and communicating with its interior through a transverse groove. A discharge pipe is installed through the bottom of the rectangular cover.

[0021] Preferably, an air inlet pipe is installed through one side of the rectangular cover, and a sealing plate extending into the rectangular cover is installed at the bottom of the air guide cover, with the sealing plate corresponding to the through end of the air inlet pipe.

[0022] In summary, this application includes at least one of the following beneficial technical effects: I. This invention integrates a crushing device at the top of the sorting frame, and together with the air screen components arranged on the four sides of the sorting frame, it realizes the simultaneous operation of crushing and disintegrating solid waste raw materials and air screen sorting. Through the air screen structure with bidirectional cooperation of forward blowing and reverse exhaust, combined with the design of the support plate reciprocating to disperse the raw materials, the raw materials are fully suspended and dispersed, improving the fullness of screening and effectively avoiding the problems of material layer accumulation and screen hole blockage.

[0023] Second, this invention uses a driving assembly consisting of a driving ring, a contact plate, and a reset push rod to achieve sequential reciprocating movement and switching of the four side air guide hoods. This ensures that the air guide hood on the blowing operation side is close to the screen plate to guarantee the air supply effect, while the air guide hood on the corresponding exhaust side is far away from the screen plate to avoid obstructing the material conveying. Combined with the bottom discharge assembly and the sealing plate that opens and closes synchronously with the air guide hood, this invention not only provides sufficient air volume for the air screening operation but also prevents raw materials from falling and clogging the air inlet pipe. At the same time, it achieves centralized collection of post-screening raw materials, improving the stability and continuity of equipment operation.

[0024] Third, the present invention uses an electric actuator-driven support assembly to not only stably support the raw materials during the air screening process, but also, after screening, allow the support plate to automatically swing along the hinge point to form a discharge slope by descending and using the limiting effect of the bending plate. This eliminates the need for an additional drive mechanism to automatically discharge the remaining impurities, simplifying the overall structure of the equipment. At the same time, it enables continuous sorting and discharge operations, improving the overall efficiency of solid waste raw material treatment. Attached Figure Description

Detailed Implementation

[0038] The following combination Figures 1 to 11 The embodiments of the present invention will be described in detail below.

[0039] This application discloses a solid waste-based ceramic tile adhesive raw material sorting, impurity removal and crushing equipment, which is used in the process of resource utilization of solid waste raw materials used in the production of solid waste-based ceramic tile adhesive. It can realize the crushing and dissociation of raw materials, air screening and impurity removal, and improve the recovery rate and screening stability of usable adhesive powder.

[0040] Example 1: Reference Figures 1 to 5As shown, a solid waste-based ceramic tile adhesive solid waste raw material sorting, impurity removal and crushing equipment includes a sorting frame 1, with a feed inlet 10 through the top of the sorting frame 1, and a crushing device (not shown in the figure) installed on the top of the sorting frame 1; the sorting frame 1 is connected to the discharge end of the bottom of the crushing device through the feed inlet 10, the sorting frame 1 has a rectangular opening around its perimeter, and a screen plate 11 for raw materials to pass through is installed in the opening; a sliding frame 12 is also installed around the sorting frame 1, and an air screen assembly 2 is installed in the sliding frame 12, the air screen assembly 2 including fan blades 13.

[0041] A discharge frame 14 is installed through the bottom of the sorting frame 1. A support component 3 is installed inside the discharge frame 14. The top of the support component 3 extends into the sorting frame 1 to support the raw materials.

[0042] In its initial state, the support component 3 is located inside the sorting box 1, providing support for the raw materials to be processed.

[0043] First, the solid waste ceramic tile adhesive raw material to be processed is poured into the crushing device from the feed end at the top. Then, the crushing device crushes the raw material, breaking up large concrete lumps and mixed large impurities in the raw material, so that the usable adhesive powder wrapped in the lumps can be fully released. At the same time, the raw material is crushed to a particle size suitable for the sieve plate 11 to avoid large materials clogging the sieve plate 11 and being unable to be effectively sorted. The crushed raw material is discharged from the discharge port at the bottom of the crushing device, and then discharged into the sorting frame 1 through the feed port 10 at the top of the sorting frame 1, falling onto the support component 3, where the support component 3 supports the raw material.

[0044] After the raw material is fed, the air screen assembly 2 in the sliding frame 12 around the sorting frame 1 is started in sequence. The fan blades 13 in the air screen assembly 2 rotate to generate directional blowing airflow, which screens out usable adhesive powder particles that meet the particle size standard from the screen plate 11 on the corresponding side, while impurities that cannot be screened are left on the support assembly 3.

[0045] After the entire process of air screening and separation is completed, the remaining raw materials on the support component 3 are driven by the support component 3 to be discharged from the bottom of the discharge frame 14 through the through-hole, thus completing the single solid waste material sorting and impurity removal operation.

[0046] Reference Figure 4 and Figure 5 As shown, the air screen assembly 2 is used to screen out the raw materials that meet the size requirements in the sorting frame 1 from the corresponding side screen plate 11; specifically, the air screen assembly 2 also includes an air guide hood 20, which is slidably installed inside the sliding frame 12. A rotating shaft 21 is rotatably inserted in the middle of the air guide hood 20, and fan blades 13 are installed on the outside of the rotating shaft 21. A rotating motor 22 is installed on one side of the air guide hood 20 through a motor base, and the main shaft of the rotating motor 22 is coaxially fixedly connected to one side of the rotating shaft 21.

[0047] The bottom of the air guide shroud 20 is provided with a through groove 23, and the bottom of the sliding frame 12 is provided with a transverse groove 24 corresponding to the through groove 23.

[0048] The rotating motor 22 drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives the outer fan blades 13 to rotate synchronously to generate directional airflow. Among them, the fan blades 13 on the purging side rotate in the forward direction, and the generated purging airflow is blown into the sorting frame 1 through the adjacent screen plate 11, blowing up the raw material on the supporting component 3. The fan blades 13 on the opposite side rotate synchronously in the reverse direction to form a negative pressure suction force, so that the raw material with the qualified particle size passes through the screen plate 11 on the corresponding side with the airflow and enters the air guide hood 20 on that side.

[0049] By operating in this cyclical manner, the present invention employs a four-sided arrangement of the air screening assembly 2. The fan blades 13 on the four sides of the sorting frame 1 start and stop sequentially in a preset opposing combination. When each fan blade 13 performs the blowing operation, the fan blade 13 on the opposite side performs the exhaust operation simultaneously, thereby achieving the effect of sequentially screening the material on the supporting assembly 3 from different angles.

[0050] The through groove 23 and the transverse groove 24 work together to allow external airflow to enter the air guide hood 20 through the transverse groove 24 and the through groove 23 during the blowing operation of the fan blade 13, thus providing sufficient airflow for the blowing operation of the corresponding fan blade 13. On the other hand, when the raw material falls into the corresponding air guide hood 20 through the screen plate 11, it can be discharged through the through groove 23 and the corresponding transverse groove 24.

[0051] Furthermore, when the fan blades 13 alternately perform ventilation and purging operations through adjacent screen plates 11, the resulting alternating airflow can cause large particles of material attached to the screen plates 11 to fall off, effectively preventing the screen holes of the screen plates 11 from becoming blocked.

[0052] In summary, it should be understood that the present invention can also be adapted to meet actual production needs by installing the sliding frame 12 and the air screen assembly 2 on only a pair of opposite sides of the sorting frame 1 to achieve basic bidirectional air screen sorting function. However, this implementation method has inherent defects: the material will gradually accumulate on the other two sides without the air screen assembly 2 under the action of the air field, forming a permanent screening dead corner, which will prevent the material in this area from being effectively sorted, and the overall screening efficiency and raw material utilization rate will decrease significantly; the corner area of ​​the screen plate 11 cannot be effectively cleaned by the alternating airflow, the probability of screen hole blockage is high, more frequent shutdown maintenance is required, and the continuous operation capability of the equipment is affected; the material can only be blown in two directions, the dispersion effect is poor, and the usable fine powder attached to the outside of large particles is difficult to be fully peeled off.

[0053] Therefore, in the case of solid waste-based ceramic tile adhesive raw material processing, where high requirements are placed on screening efficiency, raw material utilization rate and continuous operation capability, the preferred technical solution is to adopt the four-sided arrangement of the air screen assembly 2.

[0054] Reference Figure 3 and Figure 4As shown, the support assembly 3 is used to support the raw materials in the sorting frame 1. Specifically, the support assembly 3 includes a support plate 30, which is installed inside the discharge frame 14. An electric push rod 31 is installed on the top of the support plate 30. The telescopic end of the electric push rod 31 extends into the sorting frame 1 and is hinged to support plate 32. The four sides of the support plate 32 correspond to the inner side of the sorting frame 1. The support plate 32 is movably connected to the inside of the sorting frame 1, and a torsion spring is installed at the hinge.

[0055] The electric actuator 31 can drive the support plate 32 to move up and down within the sorting frame 1. When the support plate 32 supports raw materials, the electric actuator 31 can repeatedly drive the support plate 32 to move up and down, causing the raw materials on the support plate 32 to be dispersed. At this time, the corresponding fan blades 13 rotate to complete the air screening operation. During the air screening process, heavier impurities will quickly fall back onto the support plate 32. The lighter raw materials such as rubber powder can pass through the screen plate 11 with the airflow and be screened out. Through the reciprocating up and down motion of the support plate 32, the raw materials can be fully dispersed and suspended, greatly improving the screening efficiency of the air screening operation.

[0056] It should be noted that, Figure 3 The initial receiving position of the support plate 32 is shown. When the air screening operation starts, the electric push rod 31 will drive the support plate 32 to descend to the bottom area of ​​the sorting frame 1, so that the support plate 32 is completely removed from the lower coverage area of ​​the screen plate 11. At this time, the airflow provided by the air screening assembly 2 will not pass through the screen holes of the screen plate 11 below the support plate 32, ensuring that all effective air volume is applied to the raw material suspended above the support plate 32. At the same time, a small fitting gap is reserved between the four edges of the support plate 32 and the inner side of the screen plate 11. This gap can ensure that the support plate 32 will not get stuck with the screen plate 11 during the lifting and lowering process. Since the gap size is much smaller than the minimum particle size of the raw material to be processed, it can effectively prevent the raw material from falling into the discharge frame 14 from the gap.

[0057] The discharge frame 14 has grooves 33 around its perimeter, and a bent plate 34 corresponding to the bottom of the support plate 32 is installed in one side of the groove 33.

[0058] After screening, only impurities remain on the upper part of the support plate 32. At this time, the electric push rod 31 drives the support plate 32 to descend into the discharge frame 14. One side of the support plate 32 contacts the top of the bending plate 34 and swings along the hinge point. The groove 33 provides clearance for the swing of the support plate 32. After the support plate 32 tilts, the impurities at the upper part slide down the inclined surface into the discharge frame 14 and are then discharged from the discharge frame 14.

[0059] After discharge, the electric push rod 31 drives the support plate 32 back into the sorting frame 1. One side of the support plate 32 no longer contacts the top of the bending plate 34. Under the action of the torsion spring at the hinge, it automatically straightens to a horizontal state. That is, after the support plate 32 is reset, it forms a ninety-degree angle with the screen plate 11.

[0060] Reference Figure 6 and Figure 7 As shown, the sliding frame 12 and the sorting frame 1 are both equipped with a pushing assembly 4 for driving the air guide shrouds 20 to move respectively. Specifically, the pushing assembly 4 includes a pushing groove 40, which is opened on the top of the sliding frame 12. Each air guide shroud 20 has a bent driven plate 41 installed on its top. A drive ring 42 is rotatably installed on the outside of the feed port 10. An abutment plate 43 is installed on the outside of the drive ring 42. The end of the abutment plate 43 corresponding to the driven plate 41 is arc-shaped. The pushing groove 40 is used to allow the driven plate 41 to extend from the sliding frame 12 to correspond to the outside of the drive ring 42.

[0061] A reset plate 44 is fixedly installed inside the sliding frame 12. A reset push rod 45 is installed on one side of the reset plate 44. The reset push rod 45 is an existing spring push rod. The telescopic end of the reset push rod 45 is connected to one side of the air guide cover 20. The reset plate 44 is used to support the reset push rod 45.

[0062] The drive ring 42 can rotate outside the feed inlet 10. When rotating, it drives the outer contact plate 43 to swing synchronously around the axis. The contact plate 43 contacts the arc-shaped end face of each driven plate 41 in sequence, pushing the driven plate 41 to drive the corresponding air guide hood 20 to move away from the sorting frame 1 in the sliding frame 12. When the contact plate 43 disengages from the driven plate 41, the reset push rod 45 extends and retracts to drive the air guide hood 20 back to the initial position.

[0063] The purpose of this arrangement is that when one side of the fan blade 13 is blowing air, the air guide hood 20 on that side is in its initial position and close to the screen plate 11 to ensure the blowing effect; the corresponding air guide hood 20 on the other side is driven by the contact plate 43 and the driven plate 41 to move away from the corresponding screen plate 11, leaving a certain gap between it and the corresponding screen plate 11 to avoid obstructing the raw materials passing through the corresponding screen plate 11; by repeating the above steps, the sequential movement and switching of each air guide hood 20 can be achieved.

[0064] Reference Figure 4 and Figure 9 As shown, the bottom of the sliding frame 12 is equipped with a discharge component 5 that supplies airflow to the air screen assembly 2 and receives the raw materials after screening; specifically, the discharge component 5 includes a rectangular cover 50, which is installed at the bottom of the sliding frame 12 and communicates with its interior through a transverse groove 24, and a discharge pipe 51 is installed through the bottom of the rectangular cover 50.

[0065] That is, the screened raw material discharged from the transverse trough 24 will be discharged into the rectangular cover 50, and then discharged from the discharge pipe 51. In actual application, the implementers can connect several discharge pipes 51 in series through external material transport pipes to facilitate raw material collection.

[0066] An air inlet pipe 52 is installed through one side of the rectangular cover 50, and a sealing plate 53 extending into the rectangular cover 50 is installed at the bottom of the air guide cover 20. The sealing plate 53 corresponds to the through end of the air inlet pipe 52.

[0067] The air inlet pipe 52 is used to provide airflow when the fan blade 13 on the corresponding side rotates and blows air. At this time, the air guide shroud 20 is in the initial position, and the sealing plate 53 will not block the air inlet end of the air inlet pipe 52. External gas can enter the interior of the air guide shroud 20 in sequence through the rectangular cover 50, the horizontal groove 24 and the through groove 23. When the air guide shroud 20 moves away from the sorting frame 1, it will drive the sealing plate 53 to move synchronously, blocking the air inlet end of the air inlet pipe 52 to prevent raw materials from falling into the air inlet pipe 52. After the air guide shroud 20 returns to its original position, the sealing plate 53 will reset synchronously and will no longer block the air inlet pipe 52.

[0068] Example 2: Reference Figure 7 , Figure 8 , Figure 10 and Figure 11 As shown, based on Embodiment 1, a valve 6 is also installed at the end of the feed inlet 10, an internal gear ring 60 is also installed on the top of the drive ring 42, a dual-axis motor 61 is installed on the outside of the feed inlet 10 via a motor mount, a ratchet component 62 is installed on the outside of the main shaft at the bottom of the dual-axis motor 61, an external gear ring 63 that meshes with the internal gear ring 60 is fixedly sleeved on the outside of the ratchet component 62, the ratchet component 62 is a conventional unidirectional transmission ratchet tooth structure, the main shaft at the bottom of the dual-axis motor 61 and the external gear ring 63 are connected to each other through the ratchet component 62; and a second ratchet component 64 is also installed on the main shaft at the top of the dual-axis motor 61, the bottom of the valve 6 is hinged to the opening and closing shaft 65 by a torsion spring, and the opening and closing shaft 65 is connected to the second ratchet component 64, the second ratchet component 64 is also a unidirectional transmission ratchet tooth structure, the main shaft at the top of the dual-axis motor 61 and the opening and closing shaft 65 are connected to each other through the second ratchet component 64.

[0069] Valve 6 is used to block the feed inlet 10 on the sorting frame 1 when air screening is performed in the sorting frame 1 to prevent raw materials from splashing out of the feed inlet 10. Valve 6 can be opened when the crushing device pours material towards the feed inlet 10.

[0070] When the dual-axis motor 61 drives the ratchet component 62 to rotate in the forward direction via the bottom main shaft, the ratchet component 62 drives the inner gear ring 60 to rotate synchronously via the outer gear ring 63, and then drives the drive ring 42 to rotate via the inner gear ring 60, thereby realizing the sequential movement of multiple air guide covers 20; at this time, due to the unidirectional transmission characteristics of the second ratchet component 64, the second ratchet component 64 slips with the main shaft and will not drive the opening and closing shaft 65 to rotate, and the valve 6 remains in the closed state.

[0071] When valve 6 needs to be opened, the main shaft of the dual-axis motor 61 rotates in the opposite direction, which can drive the opening and closing shaft 65 to rotate synchronously through the second ratchet 64. The opening and closing shaft 65 is connected to the opening and closing mechanism inside valve 6, thereby driving valve 6 to open. At this time, due to the unidirectional transmission characteristics of the first ratchet 62, the first ratchet 62 will slip with the main shaft and will not drive the drive ring 42 to rotate, and the air guide cover 20 will remain in its original position.

[0072] When the dual-shaft motor 61 resumes forward rotation and is ready to drive the air guide hood 20 to move and carry out the air screening operation, the ratchet part 64 slips with the main shaft, and the opening and closing shaft 65 returns to the initial angle under the force of the matching torsion spring. The valve 6 closes simultaneously to avoid material splashing during the air screening process.

[0073] It should be noted that, Valve 6 adopts the existing mature shutter valve structure. The valve body has multiple annularly arranged movable valve discs, linkage forks and central transmission discs inside. The overall shape is similar to the synchronous opening and closing of a camera aperture. The opening and closing shaft is connected to the internal transmission mechanism of the shutter valve. By rotating the opening and closing shaft, the internal valve discs can be driven to synchronously close and open or close to seal, thereby realizing the controllable opening and closing of the feed port.

[0074] During operation: First, the equipment is initially reset, the support plate 32 is in the support position within the sorting frame 1, each air guide hood 20 is returned to its position close to the screen plate 11, and the valve 6 remains closed.

[0075] In the second step, the dual-shaft motor 61 rotates in the opposite direction, driving the opening and closing shaft 65 to open the valve 6 via the ratchet component 64; the solid waste raw material to be processed is poured into the crushing device, where it is crushed, the clumps are broken up, and usable adhesive powder is released, and the material is crushed to a particle size suitable for screening.

[0076] The third step is that the crushed raw material is discharged into the sorting frame 1 through the feed inlet 10 and falls stably onto the support plate 32 to complete the support.

[0077] In the fourth step, the dual-shaft motor 61 resumes forward rotation, the ratchet part 64 spins and slips, the opening and closing shaft 65 resets under the action of the torsion spring, the valve 6 closes synchronously, and the feed inlet 10 is blocked to prevent material from splashing during the air screen.

[0078] In the fifth step, the dual-axis motor 61 rotates in the forward direction, driving the drive ring 42 to rotate through the ratchet component 62. The contact plate 43 pushes each air guide hood 20 to move back and forth in sequence, realizing the sequential switching of the four side air guide hoods 20. The corresponding side rotating motor 22 starts, blowing the side fan blade 13 to deliver air in the forward direction and the opposite side fan blade 13 to draw air in the reverse direction. With the support plate 32 moving up and down in a reciprocating manner, the raw materials are dispersed in the air. Usable glue powder particles that meet the particle size standard are screened out through the sieve plate 11, while heavy impurities are retained on the support plate 32.

[0079] In the sixth step, the screened adhesive powder raw material is discharged and collected from the discharge pipe 51 through the air guide hood 20 and the rectangular cover 50; when the air guide hood 20 moves, it simultaneously drives the sealing plate 53 to open and close the air inlet pipe 52, which not only ensures the blowing air volume, but also prevents the raw material from entering the air inlet pipe 52; the fan blades 13 can clean the particles attached to the screen plate 11 by alternating airflow and prevent the screen holes from being blocked.

[0080] Step 7: After the air screening is completed, the electric push rod 31 drives the support plate 32 to descend into the discharge frame 14. After the support plate 32 contacts the bending plate 34, it swings and tilts around the hinge point. The remaining impurities slide down the inclined surface and are discharged from the equipment through the discharge frame 14.
