Description

Technical Field

[0001] This invention belongs to the field of environmental protection equipment technology, and in particular relates to a fly ash recycling device and its usage method. Background Technology

[0002] Fly ash recycling primarily follows two pathways: coal-fired fly ash and waste incineration fly ash. Coal-fired fly ash, due to its high reactivity and low cost, is the most mature resource for recycling, mainly replacing cement in high-performance concrete, precast components, and roadbed materials, thus "turning waste into building materials." High-value-added products such as alumina and cenospheres can also be extracted from it. Waste incineration fly ash, due to its high concentration of heavy metals and dioxins, is classified as hazardous waste and requires prior co-processing in cement kilns or high-temperature melting detoxification to meet standards before being processed into building material aggregates.

[0003] A Chinese patent application (or patent) with publication number CN222781421U discloses a fly ash washing liquid recycling and reuse device, including a tank. A feeding port is located on one side of the upper end of the tank, and a bottom cover is located at the lower opening of the tank. The bottom cover is detachably connected to the tank via four evenly distributed snap-fit ​​components. A filter screen is detachably installed in the bottom cover, and a drain valve is located in the center of the bottom surface of the bottom cover. After the mixing reaction is complete, the mixed liquid is discharged through the drain valve.

[0004] However, the above-mentioned device still has the following problems in the implementation process: In the fly ash treatment process, the fly ash needs to be put into the tank first and then mixed with the reactant. The unburned residue, crystals and other large particulate impurities mixed in the raw materials not only cannot react with chemical precipitation, but are also easy to accumulate and block at the conveying pump valve and pipe bends, causing the system to shut down and interfering with the overall reaction rate. At the same time, the fly ash itself is light and has good dispersibility. When it enters the tank, it is very easy to be disturbed by the airflow and generate dust. It is difficult to quickly wet and settle and combine with the reactant evenly, resulting in local reaction blind spots.

[0005] To address these issues, we provide a fly ash recycling device and its usage method. Summary of the Invention

[0006] The purpose of this invention is to provide a fly ash recycling device and its usage method. Through the structural coordination of the filtration mechanism, cleaning mechanism and conveying mechanism, it solves the problem that existing fly ash recycling equipment does not treat large particulate impurities in fly ash, thus affecting fly ash treatment efficiency.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0008] This invention relates to a fly ash recycling device and its method of use, comprising a processing shell, inside which a filtration mechanism is provided. The filtration mechanism includes a rotating tube movably connected inside the processing shell, a support shaft movably connected inside the rotating tube, a dispersing cylinder mounted on the top of the support shaft, and a filter cylinder sleeved on the surface of the dispersing cylinder. The filtration mechanism filters large particulate impurities in the fly ash. Inside the processing shell, a cleaning mechanism is provided, comprising a support disc mounted on the surface of the rotating tube, an annular scraper sleeved on the surface of the dispersing cylinder, a first gear mounted on the surface of the rotating tube, and a component meshing with one side of the first gear. The second gear, the collection shell mounted on the surface of the filter cartridge, and the control component located at the bottom of the processing shell clean the large particulate impurities filtered through the cleaning mechanism; the top of the processing shell is provided with a conveying mechanism, which includes a cover plate located on the top of the processing shell, a support cylinder installed inside the cover plate, a support filter cartridge installed inside the support cylinder, a conveying pipe connected to one side of the support filter cartridge, a first motor installed on one side of the conveying pipe, a drive shaft installed at the output end of the first motor, a conveying auger installed on the surface of the drive shaft, and a dust suppression component located on one side of the cover plate, which conveys fly ash for dust suppression.

[0009] The present invention is further configured such that the control component includes an adjustment seat installed inside the processing shell, a second motor installed on the top of the adjustment seat, a rotating disk installed on the surface of the rotating tube, a square rod installed on the bottom of the support shaft, a disc slidably connected to the surface of the square rod, a first tooth installed on the bottom of the rotating disk, a second tooth installed on the top of the disc, and the bottom of the annular scraper is fixedly connected to the support disk.

[0010] The present invention is further configured such that a fixing plate is installed on the surface of the square rod, a first spring is sleeved on the surface of the square rod, a limiting tooth is fixedly connected to the surface of the fixing plate, and a limiting rod is provided on one side of the limiting tooth.

[0011] The present invention is further configured such that the surface of the square rod is movably connected to the inner wall of the adjusting seat via a bearing, and the output end of the second motor is fixedly connected to the second gear.

[0012] The present invention is further configured such that a telescopic rod is fixedly connected to one side of the limiting rod, and a second spring is fixedly connected to the other end of the telescopic rod.

[0013] The present invention is further configured such that an agitation assembly is provided at the top of the dispersion cylinder, the agitation assembly including an internal gear ring installed at the top of the dispersion cylinder, a third gear meshing inside the internal gear ring, a rotating shaft installed at the center of the third gear shaft, and agitation blades installed on the surface of the rotating shaft.

[0014] The present invention is further configured such that a support frame is fixedly connected to the surface of the internal toothed ring, and the other end of the support frame is fixedly connected to the filter cylinder.

[0015] The present invention is further configured such that the dust suppression assembly includes a pressurized water pump installed on the top of the cover plate, a spray pipe movably connected to the inside of the supporting filter cartridge, a nozzle communicating with the surface of the spray pipe, a first bevel gear installed on the surface of the spray pipe, and a second bevel gear installed at the other end of the drive shaft.

[0016] The invention is further configured such that a delivery pipe is connected to one side of the pressurized water pump, and the other end of the delivery pipe is connected to a spray pipe. The surface of the spray pipe is movably connected to the inner wall of the delivery pipe through a bearing, and one side of the first bevel gear meshes with the second bevel gear.

[0017] A method of using a fly ash recycling device includes the following steps;

[0018] S1: The staff first transports the fly ash to be processed into the material cylinder at the top of the conveying pipe. Then, the first motor is started by the external controller. The first motor, together with the drive shaft, drives the conveying auger to rotate. The conveying auger pushes and transports the fly ash, which falls into the supporting filter cylinder. Then, the pressurized water pump is started at the same time. The pressurized water pump draws in the externally mixed reactant and water flow, pressurizes and transports it, and injects it into the spray pipe through the conveying pipe. The water flow is sprayed out through the nozzle to spray the fly ash and prevent it from being thrown up. At the same time as the drive shaft rotates, it can also drive the second bevel gear to rotate. The second bevel gear drives the spray pipe to rotate and adjusts the spray range of the nozzle. By flushing the fly ash, the fly ash is discharged through the filter holes on the surface of the supporting filter cylinder and enters the dispersion cylinder.

[0019] S2: The processing shell is filled with a mixture of reactant and water. After the wetted fly ash enters the dispersion cylinder, it can quickly blend with the reactant, improving the reaction efficiency. Then, the second motor is started. The second motor, in conjunction with the second gear, drives the first gear to rotate. The first gear drives the rotating tube to rotate counterclockwise. The rotating tube, in conjunction with the rotating disk, drives the first tooth to rotate. The first tooth, in conjunction with the second tooth, drives the disk to rotate. The disk, in conjunction with the square rod, drives the support shaft to rotate. The support shaft drives the dispersion cylinder to rotate. The dispersion cylinder, in conjunction with the internal toothed ring, drives the support frame to rotate. The support frame drives the filter cylinder to rotate. At the same time, the rotation of the rotating tube drives the support disk to rotate. The support disk drives the annular scraper to rotate, stirring the reactant inside the processing shell.

[0020] S3: The internal gear ring rotates while driving the third gear to rotate. The third gear, in conjunction with the rotating shaft, drives the stirring blades to rotate, causing the fly ash to diffuse outward and enter the filter cylinder through the dispersion cylinder. While the reactant is being stirred, the fine fly ash particles are discharged through the filter holes of the filter cylinder, fully agitated with the reactant, improving the reaction neutralization effect. Large impurities are temporarily stored between the dispersion cylinder and the filter cylinder, serving as a separation and filtration function, allowing the fly ash to fully react with the reactant.

[0021] S4: After the fly ash reaction is completed, the valve on the surface of the drain pipe on one side of the treatment shell is activated to discharge the fly ash and reactants together into the external sedimentation tank for secondary filtration. Then, the second motor is started again. The second motor, in conjunction with the second gear, drives the first gear to rotate. The first gear drives the rotating tube to rotate clockwise. The rotating tube, in conjunction with the rotating disk, drives the first tooth to rotate. While the first tooth rotates, it pushes the second tooth and the disk downward. As the disk moves downward, it slides on the surface of the square rod. At this time, the rotating tube continues to rotate, while the support shaft remains stationary under the action of the limiting teeth and the limiting rod. The support shaft, the dispersion cylinder, and the filter cylinder do not rotate. While the rotating tube rotates, it works with the support disk to drive the annular scraper to rotate. The annular scraper pushes and transports large particles of impurities between the dispersion cylinder and the filter cylinder upward through rotation, and collects them in the collection shell for easy cleaning by staff, thus improving the processing efficiency of the fly ash reaction process.

[0022] The present invention has the following beneficial effects: The present invention uses the dispersion cylinder and the filter cylinder in the filtration mechanism to perform dynamic centrifugal filtration of fly ash, effectively intercepting large particulate impurities and avoiding pipeline blockage; the annular scraper and the control component in the cleaning mechanism work together to automatically push impurities into the collection shell when rotating in the opposite direction, realizing cleaning without disassembly; the dust suppression component in the conveying mechanism sprays the reactant solution during feeding, quickly wetting the fly ash, suppressing dust and mixing in advance, and combined with the stirring blades to promote the full reaction of fine particles and reactants, significantly improving the fly ash treatment efficiency and reaction uniformity.

[0035] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Example 1

[0037] Please see Figures 1-10This invention relates to a fly ash recycling device and its usage method, comprising a processing shell 1, inside which a filtering mechanism 2 is provided. The filtering mechanism 2 includes a rotating tube 21 movably connected inside the processing shell 1, a support shaft 22 movably connected inside the rotating tube 21, a dispersing cylinder 23 mounted on the top of the support shaft 22, and a filter cylinder 24 sleeved on the surface of the dispersing cylinder 23. The filtering mechanism 2 filters large particulate impurities in the fly ash. Inside the processing shell 1, a cleaning mechanism 3 is provided, comprising a support disk 31 mounted on the surface of the rotating tube 21, an annular scraper 32 sleeved on the surface of the dispersing cylinder 23, a first gear 33 mounted on the surface of the rotating tube 21, and a second gear 3 meshing with one side of the first gear 33. 4. A collection shell 35 installed on the surface of the filter cartridge 24 and a control component 36 set at the bottom of the processing shell 1 are used to clean large particulate impurities filtered through the cleaning mechanism 3. A conveying mechanism 4 is set on the top of the processing shell 1. The conveying mechanism 4 includes a cover plate 41 set on the top of the processing shell 1, a support cylinder 42 installed inside the cover plate 41, a support filter cartridge 43 installed inside the support cylinder 42, a conveying pipe 44 connected to one side of the support filter cartridge 43, a first motor 45 installed on one side of the conveying pipe 44, a drive shaft 46 installed at the output end of the first motor 45, a conveying auger 47 installed on the surface of the drive shaft 46, and a dust suppression component 48 set on one side of the cover plate 41. The conveying mechanism 4 is used to suppress and convey fly ash.

[0038] Specifically: the processing shell 1 contains fly ash and reactants; the rotating tube 21 drives the entire filtration mechanism 2 to rotate, achieving dynamic filtration and uniformly dispersing the fly ash under centrifugal force; the support shaft 22 provides stable support for the dispersion cylinder 23 and allows relative rotation; the dispersion cylinder 23 evenly throws the incoming fly ash outward, causing it to diffuse along the cylinder wall under centrifugal force; the filter cylinder 24 physically intercepts large particles of impurities in the fly ash, allowing fine particles to pass through the filter holes while large particles are trapped; the support disk 31 rotates synchronously with the rotating tube 21 and drives the annular scraper 32 to move; the annular scraper 32 pushes the accumulated large particles of impurities upward along the inside of the filter cylinder 24 and the surface of the dispersion cylinder 23, achieving automatic cleaning; the first gear 33 receives power and changes its rotation direction; the second gear... 34 meshes with the first gear 33 to drive the rotating tube 21 to rotate forward or backward. The collection shell 35 temporarily stores the scraped large particles of impurities for centralized cleaning. The control component 36 realizes the power clutch control between the rotating tube 21 and the support shaft 22, so that when rotating forward, it drives the dispersing cylinder 23 and the filter cylinder 24 to rotate for filtration. When rotating in reverse, it only drives the annular scraper 32 to rotate for cleaning. The support filter cylinder 43 performs preliminary filtration of fly ash and guides the wet fly ash to fall. The conveying pipe 44 continuously conveys the external fly ash into the support filter cylinder 43. The first motor 45 provides rotational power to the conveying auger 47. The drive shaft 46 transmits torque to the conveying auger 47 and the dust suppression component 48. The conveying auger 47 forcibly pushes the fly ash to prevent blockage and controls the feeding speed.

[0039] Example 2

[0040] Please see Figures 1-10 Based on Embodiment 1, the control component 36 includes an adjustment seat 361 installed inside the processing housing 1, a second motor 362 installed on the top of the adjustment seat 361, a rotating disk 363 installed on the surface of the rotating tube 21, a square rod 364 installed on the bottom of the support shaft 22, a disc 365 slidably connected to the surface of the square rod 364, a first tooth 366 installed on the bottom of the rotating disk 363, a second tooth 367 installed on the top of the disc 365, a bottom of the annular scraper 32 fixedly connected to the support disk 31, a fixed disk 368 installed on the surface of the square rod 364, a first spring 369 sleeved on the surface of the square rod 364, a limiting tooth 3610 fixedly connected to the surface of the fixed disk 368, a limiting rod 3611 provided on one side of the limiting tooth 3610, a surface of the square rod 364 movably connected to the inner wall of the adjustment seat 361 through a bearing, and a second gear 34 fixedly connected to the output end of the second motor 362.

[0041] Specifically: The second motor 362 provides power to the cleaning mechanism 3. The rotating disk 363 rotates with the rotating tube 21 and drives the first tooth 366 to move. The square rod 364 connects to the support shaft 22 and allows the disk 365 to slide up and down on its surface. The disk 365 transmits or interrupts power under the drive of the rotating disk 363. The first tooth 366 and the second tooth 367 cooperate to achieve unidirectional power transmission. The second tooth 367 cooperates with the first tooth 366. When the rotating disk 363 rotates in the forward direction, it drives the disk 365 and the support shaft 22 to rotate synchronously. When it rotates in the reverse direction... When in motion, the disc 365 slides downward to disengage from the engagement. The fixed disc 368 restricts the installation position of the first spring 369 and fixes the limiting tooth 3610. The first spring 369 provides an elastic restoring force to make the disc 365 move upward. The limiting tooth 3610 and the limiting rod 3611 cooperate to restrict the unidirectional rotation of the support shaft 22, preventing the dispersion cylinder 23 from rotating accidentally when reversing. The limiting rod 3611 and the limiting tooth 3610 form a ratchet mechanism, allowing the support shaft 22 to rotate counterclockwise while preventing clockwise rotation. The telescopic rod 5 guides the telescopic movement of the limiting rod 3611.

[0042] Example 3

[0043] Please see Figures 1-10Based on Embodiments 1 and 2, a telescopic rod 5 is fixedly connected to one side of the limiting rod 3611, and a second spring 6 is fixedly connected to the other end of the telescopic rod 5. An agitation assembly 7 is provided at the top of the dispersion cylinder 23. The agitation assembly 7 includes an internal gear ring 71 installed at the top of the dispersion cylinder 23, a third gear 72 meshing inside the internal gear ring 71, a rotating shaft 73 installed at the axis of the third gear 72, and agitating blades 74 installed on the surface of the rotating shaft 73. A support frame 8 is fixedly connected to the surface of the internal gear ring 71, and the other end of the support frame 8 is fixedly connected to the filter cylinder 24. A dust suppression assembly 4... 8 includes a pressurized water pump 481 installed on the top of the cover plate 41, a spray pipe 482 movably connected to the inside of the support filter cartridge 43, a nozzle 483 connected to the surface of the spray pipe 482, a first bevel gear 484 installed on the surface of the spray pipe 482, a second bevel gear 485 installed on the other end of the drive shaft 46, a delivery pipe 486 connected to one side of the pressurized water pump 481, the other end of the delivery pipe 486 connected to the spray pipe 482, the surface of the spray pipe 482 being movably connected to the inner wall of the delivery pipe 486 through a bearing, and one side of the first bevel gear 484 meshing with the second bevel gear 485.

[0044] Specifically: the second spring 6 provides continuous pressure to keep the limiting rod 3611 pressed against the limiting tooth 3610. The inner tooth ring 71 rotates with the dispersion cylinder 23 and drives the internal gear to rotate. The third gear 72 rotates under the drive of the inner tooth ring 71 to change the direction of rotation and generate reverse stirring. The rotating shaft 73 is connected to and drives the stirring blade 74 to rotate. The stirring blade 74 applies a lateral thrust to the fly ash to make it diffuse outward. The support frame 8 rigidly connects the inner tooth ring 71 to the filter cylinder 24 to achieve synchronous rotation. The pressurized water pump 481 pressurizes the reactant solution and delivers it to the spray pipe 482. The spray pipe 482 rotates and sprays liquid to cover the entire cross section of the support filter cylinder 43. The first bevel gear 484 and the second bevel gear 485 mesh to obtain rotational power to drive the spray pipe 482 to rotate. The second bevel gear 485 rotates with the drive shaft 46 to drive the first bevel gear 484 and the spray pipe 482 to rotate synchronously. The delivery pipe 486 guides the pressurized liquid to the rotating spray pipe 482.

[0045] The working principle of this invention is as follows: The worker first transports the fly ash to be processed into the material cylinder at the top of the conveying pipe 486. Then, the first motor 45 is started by the external controller. The first motor 45, together with the drive shaft 46, drives the conveying auger 47 to rotate. The conveying auger 47 pushes and transports the fly ash, which falls into the supporting filter cylinder 43. Then, the pressurized water pump 481 is started simultaneously. The pressurized water pump 481 draws in the externally mixed reactant and water flow, pressurizes and transports it, and injects it into the spray pipe 482 through the conveying pipe 486. The water flow is sprayed out through the nozzle 483 to spray the fly ash and prevent it from being lifted. At the same time as the drive shaft 46 rotates, it can also drive the second bevel gear 485 to rotate. The second bevel gear 485 drives the spray pipe 482 to rotate, and adjusts the spray range of the nozzle 483. By flushing the fly ash, the fly ash is discharged through the filter holes on the surface of the supporting filter cylinder 43 and enters the dispersion cylinder 23.

[0046] The processing shell 1 is filled with a mixture of reactant and water. After the wetted fly ash enters the dispersion cylinder 23, it can quickly fuse with the reactant, improving the reaction efficiency. Then, the second motor 362 is started. The second motor 362, in conjunction with the second gear 34, drives the first gear 33 to rotate. The first gear 33 drives the rotating tube 21 to rotate counterclockwise. The rotating tube 21, in conjunction with the rotating disk 363, drives the first tooth 366 to rotate. The first tooth 366, in conjunction with the second tooth 367, drives the disc 365 to rotate. The disc 365, in conjunction with the square rod 364, drives the support shaft 22 to rotate. The support shaft 22 drives the dispersion cylinder 23 to rotate. The dispersion cylinder 23, in conjunction with the internal toothed ring 71, drives the support frame 8 to rotate. The support frame 8 drives the filter cylinder 24 to rotate. At the same time, the rotation of the rotating tube 21 drives the support disk 31 to rotate. The support disk 31 drives the annular scraper 32 to rotate, stirring the reactant inside the processing shell 1.

[0047] As the internal gear ring 71 rotates, it drives the third gear 72 to rotate. The third gear 72, in conjunction with the rotating shaft 73, drives the stirring blades 74 to rotate, causing the fly ash to diffuse outward and enter the filter cylinder 24 through the dispersion cylinder 23. While the reactant is being stirred, the fine fly ash particles are discharged through the filter holes of the filter cylinder 24, and are fully stirred with the reactant to improve the neutralization effect of the reaction. Large impurities are temporarily stored between the dispersion cylinder 23 and the filter cylinder 24, which plays a role in separation and filtration, allowing the fly ash to fully react with the reactant.

[0048] After the fly ash reaction is completed, the valve on the surface of the drain pipe on one side of the treatment shell 1 is activated to discharge the fly ash and reactants together into the external sedimentation tank for secondary filtration. Then, the second motor 362 is activated again. The second motor 362, in conjunction with the second gear 34, drives the first gear 33 to rotate. The first gear 33 drives the rotating tube 21 to rotate clockwise. The rotating tube 21, in conjunction with the rotating disk 363, drives the first tooth 366 to rotate. While the first tooth 366 rotates, it pushes the second tooth 367 and the disk 365 to move downward. As the disk 365 moves downward, it moves along the square rod 36. 4. Surface sliding: At this time, the rotating tube 21 continues to rotate, and the support shaft 22 remains stationary under the action of the limiting tooth 3610 and the limiting rod 3611. The support shaft 22, the dispersing cylinder 23, and the filter cylinder 24 do not rotate. While the rotating tube 21 rotates, it works in conjunction with the support disc 31 to drive the annular scraper 32 to rotate. The annular scraper 32 pushes and transports large particles of impurities between the dispersing cylinder 23 and the filter cylinder 24 upward through rotation, and collects them into the collection shell 35 for easy cleaning by staff, thus improving the processing efficiency in the fly ash reaction process.

10. A method of using a fly ash recycling device, based on the fly ash recycling device according to any one of claims 1-9, characterized in that, Includes the following steps; S1: The worker first transports the fly ash to be processed into the material cylinder at the top of the conveying pipe (486), and then starts the first motor (45) through the external controller. The first motor (45) and the drive shaft (46) drive the conveying auger (47) to rotate. The conveying auger (47) pushes and transports the fly ash, which falls into the support filter cylinder (43). Then, the pressurized water pump (481) is started simultaneously. The pressurized water pump (481) draws in the externally mixed reactant and water flow, and pressurizes and transports it. The feed pipe (486) is injected into the spray pipe (482), and water is sprayed out through the nozzle (483) to spray the fly ash and prevent it from being lifted. While the drive shaft (46) rotates, it can synchronously drive the second bevel gear (485) to rotate. The second bevel gear (485) drives the spray pipe (482) to rotate, and adjusts the spray range of the nozzle (483). By flushing the fly ash, the fly ash is discharged through the filter holes on the surface of the support filter cylinder (43) and enters the dispersion cylinder (23). S2: The processing shell (1) is filled with a mixture of reactant and water. After the wetted fly ash enters the dispersion cylinder (23), it can quickly fuse with the reactant, improving the reaction efficiency. Then, the second motor (362) is started. The second motor (362) works with the second gear (34) to drive the first gear (33) to rotate. The first gear (33) drives the rotating tube (21) to rotate counterclockwise. The rotating tube (21) works with the rotating disk (363) to drive the first tooth (366) to rotate. The first tooth (366) works with the second gear (364) to rotate counterclockwise. The two teeth (367) drive the disc (365) to rotate. The disc (365) and the square rod (364) drive the support shaft (22) to rotate. The support shaft (22) drives the dispersion cylinder (23) to rotate. The dispersion cylinder (23) and the internal toothed ring (71) drive the support frame (8) to rotate. The support frame (8) drives the filter cylinder (24) to rotate. The rotating tube (21) rotates while driving the support disk (31) to rotate. The support disk (31) drives the annular scraper (32) to rotate, stirring the reactant inside the treatment shell (1). S3: The internal gear ring (71) rotates while driving the third gear (72) to rotate. The third gear (72) works with the rotating shaft (73) to drive the stirring blades (74) to rotate, causing the fly ash to diffuse outward and enter the filter cylinder (24) through the dispersion cylinder (23). While the reactant is being stirred, the fine fly ash particles are discharged through the filter holes of the filter cylinder (24) and are fully stirred with the reactant to improve the reaction neutralization effect. Large particles of impurities are temporarily stored between the dispersion cylinder (23) and the filter cylinder (24) to play a role in separation and filtration, so that the fly ash and the reactant can fully react. S4: After the fly ash reaction is completed, the valve on the surface of the drain pipe on one side of the treatment shell (1) is activated to discharge the fly ash and reactant together into the external sedimentation tank for secondary filtration. Then, the second motor (362) is activated again. The second motor (362) and the second gear (34) drive the first gear (33) to rotate. The first gear (33) drives the rotating tube (21) to rotate clockwise. The rotating tube (21) and the rotating disk (363) drive the first tooth (366) to rotate. While the first tooth (366) rotates, it pushes the second tooth (367) and the disk (365) to move downward. While the disk (365) moves downward, it pushes the square rod ( 364) Surface sliding, at this time the rotating tube (21) continues to rotate, the support shaft (22) remains stationary under the action of the limiting tooth (3610) and the limiting rod (3611), the support shaft (22), the dispersion cylinder (23) and the filter cylinder (24) do not rotate, the rotating tube (21) rotates at the same time and cooperates with the support plate (31) to drive the annular scraper (32) to rotate, the annular scraper (32) pushes the large particles of impurities between the dispersion cylinder (23) and the filter cylinder (24) upward through the rotation action, and enters the collection shell (35) for collection, which is convenient for the staff to clean in a concentrated manner and improves the processing efficiency in the fly ash reaction process.
