Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of quartz sand processing, in particular to a quartz sand washing crusher. BACKGROUND

[0002] The existing quartz sand processing usually needs to go through the core links of secondary crushing, screening and cleaning. In the conventional process, crushing and cleaning are independent processes, and the quartz sand crushed for the second time needs to be transferred to the cleaning equipment through additional conveying equipment, which has obvious process connection fault problems. The particle size of the quartz sand crushed for the second time has large differences, and needs to be classified through the screening link, and then the large particle quartz sand is sent into the crushing equipment again to be crushed to the appropriate particle size, which increases the work task amount. In the cleaning link, spiral sand washers, drum sand washers and groove scrubbing machines are usually used. Such equipment adopts single soaking, flushing or spraying methods. During the cleaning process, the quartz sand is always soaked in the sewage containing mud, and a small amount of sewage is still attached to the surface of the quartz sand when it is output. Although most of the surface water can be removed through the vibrating screen, a small amount of mud will still remain on the surface of the sand, causing secondary pollution of the quartz sand, and ultimately leading to low overall processing efficiency, high cost and difficult to guarantee the purity of the product.

[0012] The beneficial effects of this invention compared to existing technologies are as follows: This device, through its integrated design of pre-cleaning, crushing, deep cleaning, and material conveying, effectively solves the pain points in existing quartz sand processing, such as poor process connection, uneven particle size, incomplete cleaning, resource waste, and secondary pollution. Specifically:

[0013] 1. The equipment achieves simultaneous cleaning and crushing, improving processing efficiency while ensuring uniform particle size of quartz sand; it reduces water consumption through water recycling and precise spraying design; and with impurity filtration, timely waste liquid discharge and seamless material conveying structure, it significantly improves the purity of quartz sand, reduces equipment wear, and balances processing efficiency, product quality and environmental protection requirements, significantly reducing overall processing costs.

[0014] 2. The flow guiding mechanism in the pre-cleaning tank drives water circulation, which makes the quartz sand evenly dispersed and avoids local accumulation. The crushing mechanism simultaneously squeezes and grinds the dispersed large particles of quartz sand. The water environment can absorb the heat generated by crushing in time, reducing the wear of crushing parts. The two work together to ensure that the quartz sand after crushing is uniform in size, and the pre-cleaning removes the surface dust, laying the foundation for subsequent deep cleaning. Compared with traditional sequential processing, the efficiency is significantly improved.

[0015] 3. The liquid delivery mechanism uses a water pump to draw water that has already undergone preliminary cleaning and still has cleaning ability from the lower cleaning tank. After pressurization, the water is precisely applied to the crushing area through a high-pressure nozzle, realizing the recycling of cleaning water and reducing the consumption of fresh water resources. At the same time, the high-pressure water flow can help to push the material to crush and prevent accumulation, which is in line with the concept of green processing.

[0016] 4. The pusher platform at the bottom of the guide turntable can push the material at the bottom of the pre-cleaning box to the discharge port. The feeding mechanism drives the lifting frame through the cylinder, so that the material protection trough platform is precisely aligned with the discharge protection plate and the inlet trough platform to form a closed conveying channel and prevent material spillage. The blocking plate can precisely control the discharge timing to achieve seamless connection between the pre-cleaning box and the lower cleaning box, ensuring a clean and efficient conveying process.

DETAILED DESCRIPTION

[0033] The present application will be further described in detail in combination with the accompanying drawings.

[0034] In combination with the accompanying Figure 1 , the accompanying Figure 2 , the accompanying Figure 3 and the accompanying Figure 6As shown, a quartz sand washing crusher, including frame 1, frame 1 is provided with the lower washing tank 7, the inside of the lower washing tank 7 is provided with a screw conveyor 8, the top of the frame 1 is provided with a top plate 11, the bottom of the top plate 11 is provided with a pre-washing tank 2, the lower washing tank 7 and the pre-washing tank 2 are provided with a feeding mechanism 6, the pre-washing tank 2 is provided with a flow guide mechanism 3 and a crushing mechanism 4, the flow guide mechanism 3 includes a driver one 31 and a flow guide turntable 32, the flow guide turntable 32 is hung on the bottom of the top plate 11, the driver one 31 drives the flow guide turntable 32 to rotate inside the pre-washing tank 2, the crushing mechanism 4 includes a driver two 41 and a crushing cone 42, the driver two 41 drives the crushing cone 42 to rotate inside the pre-washing tank 2, the top plate 11 is provided with a feeding platform 12, the feeding mechanism 6 transports the material inside the pre-washing tank 2 to the lower washing tank 7, and the screw conveyor 8 transports the material out of the lower washing tank 7.

[0035] In the process of quartz sand processing, the size of the particles after secondary crushing is often uneven, and the connection between washing and crushing is not smooth, resulting in low processing efficiency. The quartz sand washing crusher solves the above problems through the integrated design of pre-washing, crushing and deep cleaning structure, realizes efficient purification and size regulation of quartz sand.

[0036] When the equipment is working, first of all, the quartz sand raw material after secondary crushing is put into the pre-washing tank 2 through the feeding platform 12 on the top plate 11, at this time, the flow guide mechanism 3 and the crushing mechanism 4 are started synchronously, the driver one 31 in the flow guide mechanism drives the flow guide turntable 32 to rotate inside the pre-washing tank 2, the rotation of the flow guide turntable 32 can guide the water inside the pre-washing tank 2, so that the water inside the pre-washing tank 2 rotates regularly, which can disperse the quartz sand raw material, avoid local accumulation of the raw material in the pre-washing tank 2, and realize the sinking of large particle quartz sand and the dispersion of small particle quartz sand with water flow outside through water rotation, which can also cooperate with the water in the pre-washing tank 2 to preliminarily flush the dust and other light impurities attached to the surface of the quartz sand.

[0037] The driver two 41 in the crushing mechanism 4 drives the crushing cone 42 to rotate inside the pre-washing tank 2, the crushing cone 42 and the inner wall of the pre-washing tank 2 form a gradually changing crushing gap, with the rotation of the crushing cone 42, the dispersed large particle quartz sand is extruded and ground, and the large particle quartz sand is processed to a uniform particle size that meets the subsequent processing requirements. In this process, pre-washing and crushing are carried out synchronously, which not only reduces the wear of the crushing parts during separate crushing, but also cools the heat generated during crushing in water environment, and improves the particle size uniformity of the quartz sand.

[0038] The quartz sand material after pre-cleaning and crushing is conveyed to the lower cleaning box 7 through the feeding mechanism 6 arranged between the lower cleaning box 7 and the pre-cleaning box 2, and the material entering the lower cleaning box 7 will receive further deep cleaning to remove residual fine impurities; at the same time, the spiral conveyor 8 arranged inside the lower cleaning box 7 is started, and in the process of conveying the material, the spiral conveyor 8 can make the material fully contact with water through the stirring action of the spiral blade 821, further strengthening the cleaning effect, and finally, the quartz sand material that meets the purity requirements after deep cleaning will be sent out of the lower cleaning box 7 under the continuous conveying of the spiral conveyor 8, completing the whole process of washing and crushing of the quartz sand.

[0039] In combination with the drawings of Figure 4 , the drawings of Figure 5 and the drawings of Figure 8 , the driver one 31 includes a motor and a reducer box driven umbrella tooth one 311, the top of the flow guide turntable 32 is provided with a tooth ring one 321 engaged with the umbrella tooth one 311, the middle section of the flow guide turntable 32 is provided with a flow dividing plate 322, the flow guide turntable 32 on both sides of the flow dividing plate 322 is respectively provided with an outer flow window 323 and an inner flow window 325, the outer flow window 323 and the inner flow window 325 are respectively provided with a flow guide plate one 324 and a flow guide plate two 326 with opposite directions, and the bottom inside of the flow guide turntable 32 is provided with a liquid pushing plate 328.

[0040] In the process of simultaneous pre-cleaning and crushing of the quartz sand, if the raw material only relies on natural falling into the pre-cleaning box 2, local accumulation is easy to occur, leading to uneven force on the crushing mechanism 4, reduced crushing efficiency, different particle sizes of the quartz sand cannot be distinguished, leading to reduced crushing efficiency, and the cleaning medium flows slowly and cannot fully contact with the quartz sand, so that the surface impurities cannot be efficiently removed, while the flow guide turntable 32 can effectively solve the problems of material accumulation and insufficient contact of the cleaning medium through specific transmission structure and flow guide design, ensuring the coordinated and efficient performance of the pre-cleaning and crushing link.

[0041] When the driver 31 starts, the power output by its motor is transmitted to the bevel gear 311 after the speed is adjusted by the reduction gearbox. Since the gear ring 321 on the top of the guide turntable 32 meshes with the bevel gear 311, the rotation of the bevel gear 311 will drive the gear ring 321 and the entire guide turntable 32 to rotate stably inside the pre-cleaning tank 2. As the guide turntable 32 continues to rotate, the liquid pusher plate 328 provided on the inner bottom of the guide turntable 32 will push the water in the pre-cleaning tank 2 to form a circulating flow when the guide turntable 32 rotates. At the same time, the guide plates 324 and 326 on the outer flow window 323 and the inner flow window 325 will further agitate the water during the rotation. Radial flow guidance: the second guide plate 326 on the inner flow window 325 causes water to flow from the outside of the guide turntable 32 through the inner flow window 325 to the inside. The first guide plate 324 is set in the opposite direction to the second guide plate 326, so that the first guide plate 324 on the outer flow window 323 drives water from the inside of the guide turntable 32 through the outer flow window 323 to the outside. In this cycle, the diversion plate 322 prevents the radial water flows in opposite directions from affecting each other. After diversion, the small particles of quartz sand will flow with the water. The flowing water can contact the evenly distributed quartz sand more fully, thereby achieving the uniform distribution of quartz sand in the pre-cleaning tank 2 and enhancing the scouring effect on light dust impurities on the surface of quartz sand.

[0042] Combined with appendix Figure 5 Appendix Figure 7 and attached Figure 11 As shown, the pre-cleaning tank 2 has a conical platform 21 on the inner side of its bottom. The crushing conical platform 42 is rotatably mounted on the bottom of the conical platform 21. The second driver 41 includes a motor and a gearbox driving a bevel gear 411. The bottom of the crushing conical platform 42 has a toothed ring 425 that meshes with the bevel gear 411. The outer side of the bottom of the conical platform 21 has a grinding ring 24. The outer side of the inclined surface of the crushing conical platform 42 has a conveying groove 421. The outer side of the bottom of the crushing conical platform 42 has a crushing groove 422 that communicates with the conveying groove 421. The crushing groove 422 has an arc-shaped grinding table 423 that cooperates with the grinding ring 24.

[0043] In the crushing stage after pre-washing of quartz sand, if only conventional crushing structures are used, large pieces of quartz sand are easily not crushed completely, and the particle size of the crushed material is uneven. Furthermore, in a water environment, quartz sand tends to adhere to the cavity wall, and the material tends to accumulate below the crushing area, causing obstruction of conveying and affecting the crushing process. However, the crushing cone 42, through its design in conjunction with the cone 21 and its own special trough structure, can effectively solve the problems of incomplete crushing and poor material conveying, ensuring high efficiency and high quality in the quartz sand crushing stage.

[0044] When the second driver 41 starts, the power output of its motor is adjusted to the appropriate crushing speed by the reduction gearbox and then transmitted to the second bevel tooth 411. Since the second tooth ring 425 at the bottom of the crushing cone 42 meshes with the second bevel tooth 411, the rotation of the second bevel tooth 411 will drive the second tooth ring 425 and the entire crushing cone 42 to rotate stably at the bottom of the cone 21. The large particles of quartz sand that have been freely falling from the feed platform 12 fall to the inclined area of ​​the crushing cone 42. The conveying trough 421 provided on the outer side of the inclined surface of the crushing cone 42 can guide the falling quartz sand to the bottom of the crushing cone 42 through the guiding effect of the trough during the rotation of the crushing cone 42, so as to avoid the accumulation of materials on the inclined surface and ensure the continuous and stable crushing process.

[0045] As the quartz sand is conveyed to the bottom of the crushing cone 42, it undergoes initial crushing in the crushing trough 422 located on the outer side of the bottom. The grinding ring 24 located on the outer side of the bottom of the cone 21 and the arc-shaped grinding table 423 on the crushing trough 422 work together to exert targeted compression and shearing forces on the quartz sand, crushing large pieces of quartz sand into smaller particles. When the crushing cone 42 rotates, the grinding gap formed between the outer ring of the bottom of the crushing cone 42 and the grinding ring 24 can further grind and refine the initially crushed quartz sand, making the material particle size more uniform and removing hard impurities attached to the surface of the quartz sand through grinding, thereby improving the purity of the quartz sand. Throughout the process, the conveying function of the conveying trough 421, the crushing function of the arc-shaped grinding table 423 and the grinding ring 24, and the grinding function of the outer ring of the crushing cone 42 and the grinding ring 24 work together to solve the problem of connecting material conveying and crushing, and to achieve integrated processing of crushing and grinding, providing a material basis with uniform particle size and low impurity content for the subsequent deep cleaning in the lower cleaning box 7.

[0046] Combined with appendix Figure 9 Appendix Figure 10 and attached Figure 12 As shown, the pre-cleaning tank 2 is provided with a liquid delivery mechanism 5 at the bottom. The liquid delivery mechanism 5 includes a water pump 51 and a liquid distribution platform 54. The water pump 51 is provided with an inlet pipe 52 and an outlet pipe 53 at its input and output ends, respectively. The inlet pipe 52 extends into the lower cleaning tank 7, and the end of the outlet pipe 53 extends into the liquid distribution platform 54 and is rotatably connected to the liquid distribution platform 54. The liquid distribution platform 54 is provided with multiple liquid distribution pipes 55, and the end of the liquid distribution pipe 55 is provided with a high-pressure nozzle 56. The crushing tank 422 is provided with an installation groove 424 for placing the high-pressure nozzle 56. The pre-cleaning tank 2 is provided with a waste liquid discharge port.

[0047] Combined with appendix Figure 5 and attached Figure 10 As shown, the bottom of the feeding platform 12 is provided with a mesh cage 13 connected to the top of the conical platform 21, and the top of the crushing cone platform 42 is provided with a spiral platform 43 extending into the mesh cage 13.

[0048] In the quartz sand pre-cleaning and crushing link, if water only relies on natural injection, it is easy to cause the crushed material to accumulate at the bottom of the crushing cone 42, and large impurities may enter the crushing system with the raw material, affecting the service life of the crushing components, and the waste liquid containing impurities after cleaning cannot be discharged in time, causing secondary pollution. The liquid feeding mechanism 5 solves the problems of water waste, inaccurate cleaning, raw material impurity interference and waste liquid accumulation through water circulation design and precise spraying structure, cooperates with the mesh cage 13 at the bottom of the feeding table 12 and the spiral table 43 at the top of the crushing cone 42, and effectively solves the problems of water waste, inaccurate cleaning, raw material impurity interference and waste liquid accumulation, ensuring the efficiency and environmental protection of the pre-cleaning link.

[0049] When the liquid feeding mechanism 5 is started, the water pump 51 first starts to work, the input end thereof extends into the lower cleaning tank 7 through the liquid inlet pipe 52, and the water pump 51 extracts the water in the lower cleaning tank 7 which has participated in the preliminary cleaning and still has a certain cleaning capacity, realizes the recycling of water, and avoids water resource waste; the output end of the water pump 51 delivers the extracted liquid to the liquid distribution table 54 after being pressurized through the liquid outlet pipe 53. Since the end of the liquid outlet pipe 53 is rotationally connected with the liquid distribution table 54, the liquid distribution table 54 can rotate synchronously with the crushing cone 42 during the rotation of the crushing cone 42, ensuring that the subsequent spraying direction and the crushing area always correspond; the liquid distribution table 54 is provided with a plurality of liquid distribution pipes 55, the pressurized liquid is distributed to each liquid distribution pipe 55 through the liquid distribution table 54, and then forms a high-pressure jet flow through the high-pressure nozzles 56 at the ends of the liquid distribution pipes 55. The high-pressure nozzles 56 are just placed in the mounting groove 424 of the crushing groove 422, so that the high-pressure jet flow directly acts on the quartz sand in the crushing groove 422. On the one hand, the high-pressure jet flow can quickly remove the dust generated during the crushing process of the quartz sand and the impurities attached to the surface of the quartz sand, and on the other hand, the high-pressure jet flow can push the quartz sand to the arc-shaped grinding table 423 and the grinding ring 24 for crushing, avoiding the accumulation of the quartz sand in the crushing groove 422. In addition, the high-pressure jet flow can also assist in reducing the temperature generated by friction of the crushing components, prolonging the service life of the crushing cone 42.

[0050] The mesh cage 13 at the bottom of the feed platform 12 is connected to the top of the conical platform 21. When the quartz sand is fed from the feed platform 12, it first passes through the mesh cage 13. The spiral platform 43 at the top of the crushing cone 42 extends into the mesh cage 13 and rotates synchronously with the crushing cone 42. The spiral structure allows the water supplied by the liquid delivery mechanism 5 to be transported from the bottom of the crushing cone 42 to the mesh cage 13, and the water in the mesh cage 13 is in a rotating state. At the same time, this water flow will slow down the falling speed of the quartz sand and drive the quartz sand to rotate with the water flow. During the rotation, centrifugal force is used to accelerate the quartz sand. The force is used to screen large particles of quartz sand in the raw material through the mesh cage 13, so that small particles of quartz sand will enter the pre-cleaning box 2 outside the mesh cage 13, while large particles of quartz sand will gradually fall to the crushing system below. Since the water delivered by the liquid delivery mechanism 5 can flow to the mesh cage 13, it generates an upward water flow, which can carry the crushed quartz sand from the crushing tank 422 position to the mesh cage 13 position with the water flow. The outward rotating water flow at the mesh cage 13 will send the small particles of quartz sand to the outside of the mesh cage 13, realizing the transportation of small particles of quartz sand.

[0051] External water is directly supplied to the lower cleaning tank 7. The water in the lower cleaning tank 7, which still has a certain cleaning capacity, is supplied to the pre-cleaning tank 2 through the liquid delivery mechanism 5. As the pre-cleaning process progresses, the cleaning capacity of the water in the pre-cleaning tank 2 decreases (the content of mud and dust impurities increases). Some wastewater is periodically discharged through the waste liquid outlet on the pre-cleaning tank 2. The water level in the pre-cleaning tank 2 has a certain fluctuation range to ensure the continuous operation of the first cleaning and to periodically reduce the impurity content in the pre-cleaning tank 2. Throughout the process, the secondary use of water, precise spraying, raw material filtration and transportation, and waste liquid discharge work together to improve the pre-cleaning effect and resource utilization rate, while ensuring the stable operation of the crushing process.

[0052] Combined with appendix Figure 5 Appendix Figure 7 Appendix Figure 8 Appendix Figure 13 and attached Figure 14 As shown, the bottom of the guide turntable 32 is evenly provided with multiple pusher platforms 327. The pusher platforms 327 rotate at the bottom of the pre-cleaning tank 2. The bottom of the pre-cleaning tank 2 is provided with multiple discharge ports 22. Below the discharge ports 22, there is a discharge guard plate 23. The lower cleaning tank 7 is provided with an inlet trough platform 71 at the corresponding position of the discharge port 22. The feeding mechanism 6 includes a cylinder 61 and a lifting frame 62. The lifting frame 62 is provided with multiple guard trough platforms 63. The guard trough platforms 63 slide in cooperation with the discharge guard plate 23 and the inlet trough platform 71. The inner side of the guard trough platform 63 is provided with a blocking plate 64 that is inserted into the discharge port 22.

[0053] Combined with appendix Figure 14As shown, the lower cleaning tank 7 is provided with a ring groove 72 on the top inner side, and a ring pipe 73 is arranged in the ring groove 72, and the ring pipe 73 is connected with an external water source conveying device, and a plurality of spray heads 74 are arranged on the ring pipe 73.

[0054] After the quartz sand is pre-cleaned and broken, it needs to be conveyed from the pre-cleaning tank 2 to the lower cleaning tank 7 for deep cleaning. During this process, the material may accumulate at the bottom of the pre-cleaning tank 2 and be difficult to discharge, the material may spill during conveying, causing waste and pollution, the feeding connection between the pre-cleaning tank 2 and the lower cleaning tank 7 may not be smooth, resulting in low conveying efficiency, and the material received by the lower cleaning tank 7 cannot be timely preliminary washed, affecting the deep cleaning effect. The feeding mechanism 6, through the lifting type material protection and plugging structure, in cooperation with the material pushing effect of the flow guide turntable 32 and the ring pipe spraying design of the lower cleaning tank 7, can effectively solve the problems of material accumulation, material leakage, unsmooth connection and untimely feeding and cleaning, and ensure efficient, clean material conveying and smooth deep cleaning.

[0055] When the quartz sand in the pre-cleaning tank 2 is pre-cleaned and broken, a plurality of material pushing tables 327 are evenly arranged at the bottom of the flow guide turntable 32, which will rotate synchronously with the flow guide turntable 32 at the bottom of the pre-cleaning tank 2. During the rotation of the material pushing table 327, the material accumulated at the bottom of the pre-cleaning tank 2 can be pushed, and the material can be gradually pushed to the plurality of discharge ports 22 arranged at the bottom of the pre-cleaning tank 2, so as to avoid long-term accumulation and blockage of the discharge channel. At this time, the feeding mechanism 6 is started, and the cylinder 61 starts to work as a power source to drive the lifting frame 62 to drive the plurality of material protection groove tables 63 arranged thereon to ascend and descend. Since the material protection groove table 63 is in sliding cooperation with the discharge protection plate 23 and the material inlet groove table 71, when the lifting frame 62 descends, the material protection groove table 63 will be accurately connected below the discharge protection plate 23 and above the material inlet groove table 71, forming a closed material conveying channel. At the same time, the blocking plate 64 arranged on the inner side of the material protection groove table 63 will be disconnected from the insertion cooperation with the discharge port 22, so that the discharge port 22 is opened. Under the continuous pushing of the material pushing table 327, the material in the pre-cleaning tank 2 falls into the material protection groove table 63 through the discharge port 22, and then is stably conveyed to the lower cleaning tank 7 through the material inlet groove table 71 under the guidance of the material protection groove table 63. During the entire conveying process, the sliding cooperation of the material protection groove table 63 with the discharge protection plate 23 and the material inlet groove table 71 effectively prevents the material from spilling, solving the problem of material leakage during conveying.

[0056] When the material is transported to the lower washing tank 7, the ring pipe 73 provided in the inner side ring groove 72 at the top of the lower washing tank 7 starts to work. The ring pipe 73 is connected with an external water source conveying device. After the external water source is branched through the ring pipe 73, the water is sprayed to the material falling into the lower washing tank 7 through the multiple spray heads 74 provided on the ring pipe 73, so as to preliminarily wash the material and avoid the material from adhering to the inner wall of the lower washing tank 7, and to supplement water for the lower washing tank 7. When the material transportation is completed, the air cylinder 61 drives the lifting frame 62 to rise, drives the material protection groove table 63 to reset, and drives the blocking plate 64 to reinsert and cooperate with the discharge port 22, so as to close the discharge port 22 and prevent the subsequent material in the pre-washing tank 2 from being leaked in advance. Through the working process, the feeding mechanism 6 realizes efficient and clean transportation of the material between the pre-washing tank 2 and the lower washing tank 7, and further improves the cleaning effect of the quartz sand in cooperation with the ring pipe spraying structure of the lower washing tank 7.

[0057] The drawings are attached Figure 3 and the drawings are attached Figure 15 As shown in the drawings, the spiral conveyor 8 comprises a motor 81 and two driving shafts 82. The motor 81 is provided with a belt pulley one 811 at the output end. The driving shaft 82 is provided with a belt pulley two 822 at one end. The two belt pulley twos 822 are connected through a belt transmission. One of the belt pulley twos 822 is connected with the belt pulley one 811 through a belt transmission. The two driving shafts 82 rotate in the lower washing tank 7. The driving shaft 82 is provided with a spiral blade 821. The lower washing tank 7 is provided with an inclined table 75. The two driving shafts 82 are obliquely arranged on the inclined table 75. The inclined table 75 is hingedly provided with a vibrating discharge plate 76 at the end.

[0058] After the quartz sand is deeply cleaned in the lower washing tank 7, the clean material needs to be transported out of the equipment. The spiral conveyor 8 is designed by double driving shaft linkage transmission, oblique installation, spiral blade, and vibrating discharge plate at the end of the inclined table, so as to ensure efficient and complete transportation of the quartz sand after cleaning.

[0059] When the spiral conveyor 8 starts to work, the motor 81 starts to work as a power source. The belt pulley one 811 provided at the output end rotates. Since one of the belt pulley twos 822 at the end of the driving shaft 82 is connected with the belt pulley one 811 through a belt transmission, the rotation of the belt pulley one 811 drives the belt pulley two 822 and the corresponding driving shaft 82 to rotate. At the same time, the belt pulley twos 822 at the ends of the two driving shafts 82 are connected through a belt transmission, so that the other driving shaft 82 also rotates synchronously, realizing linkage operation of the double driving shafts 82. When the double driving shafts 82 rotate in the lower washing tank 7, the spiral blades 821 provided on the shafts rotate synchronously. At the same time, the rotation of the spiral blades 821 can fully stir the material at the bottom of the lower washing tank 7, achieving a secondary cleaning effect.

In general, if a person skilled in the art is inspired thereby, without departing from the spirit of the present application, without creating a similar structure and embodiment of the technical solution, which should belong to the protection scope of the present application.
