Description

Technical Field

[0001] The present application relates to the technical field of waste recycling equipment, and particularly to a waste recycling and reuse equipment in concrete production. Background Art

[0002] With the acceleration of the urbanization process, the demand for concrete in the construction industry is increasing continuously, and various construction waste concretes are also increasing. How to effectively process these wastes has become an urgent problem to be solved. At present, the main methods adopted by many enterprises are to directly discard or landfill the wastes, which not only wastes resources but also seriously pollutes the environment. In recent years, some research institutions and enterprises have made certain progress in exploring the recycling and reuse of wastes, but there are still many challenges.

[0003] The existing recycling and utilization of waste concrete mainly adopts the physical crushing method. The waste concrete is multi-stage crushed by a large crusher to break the waste concrete into particles of a certain size for reuse as aggregate. This method is simple and easy to operate and is suitable for large-scale industrial production.

[0004] However, due to the diverse sources of waste concrete, its composition and physical properties may vary greatly. At the same time, when the waste concrete is crushed and recycled, it is easy to make the surface of the final product have a large number of loose particles and micro-cracks, increasing the porosity and water absorption, and ultimately greatly reducing the quality of the recycled product of waste concrete, which is not conducive to reusing as aggregate again. Summary of the Invention

[0005] In order to improve the quality of the recycled product of waste concrete crushing, the present application provides a waste recycling and reuse equipment in concrete production.

[0006] A waste recycling and reuse equipment in concrete production provided by the present application adopts the following technical solutions: A waste recycling and reuse equipment in concrete production includes a frame. A crushing mechanism for multi-stage crushing of waste concrete is arranged on the frame. A cleaning mechanism for cleaning the material discharged from the crushing mechanism is arranged on the frame. The cleaning mechanism includes: A temporary storage member, which is arranged on the frame and used for temporarily storing the material discharged from the crushing mechanism; A cleaning cylinder, which is arranged on the frame. The material discharged from the temporary storage member is cleaned by cleaning liquid in the cleaning cylinder; A cleaning driving member, which is arranged on the cleaning cylinder and used for driving the cleaning liquid and the material in the cleaning cylinder to rotate and clean and grind the material; Discharging assembly, which is arranged on the frame and used to discharge the materials after cleaning in the cleaning cylinder.

[0007] By adopting the above technical solution, the crushing mechanism performs multi-stage crushing treatment on waste concrete, temporarily stores the crushed materials through the temporary storage part, then discharges a certain amount of crushed materials into the cleaning cylinder, drives the cleaning liquid and materials in the cleaning cylinder to perform cleaning and grinding through the cleaning driving part, and discharges the impurities and cleaning liquid washed down through the discharging assembly, so as to remove the loose particles and soft layers on the surface of the crushed materials, and at the same time adjust the particle size and shape of the materials, and finally improve the quality of the waste concrete crushing and recycling products.

[0008] Furthermore, multiple groups of protrusions are arranged at intervals on the cleaning cylinder, grinding sheets for frictionally grinding the materials are arranged on the protrusions, and multiple groups of water spraying parts are arranged at intervals inside the cleaning cylinder, and the water spraying parts are used to spray high-pressure water flow and impact the surface of the materials.

[0009] By adopting the above technical solution, when the cleaning liquid and materials in the cleaning cylinder rotate, the materials rub against the grinding sheets on the protrusions, and at the same time the water spraying parts spray high-pressure water flow, and the high-pressure water flow impacts the surface of the rotating materials, so as to improve the cleaning and grinding effects on the materials.

[0010] Furthermore, the cleaning driving part includes: Rotating disk, which is rotatably arranged on the inner bottom of the cleaning cylinder and used to drive the cleaning liquid and materials in the cleaning cylinder to rotate; Cleaning driving motor, which is arranged on the cleaning cylinder and used to drive the rotating disk to rotate; Controller, which is arranged on the cleaning cylinder and used to control the intermittent forward and reverse rotation of the cleaning driving motor.

[0011] By adopting the above technical solution, the controller controls the intermittent forward and reverse rotation of the cleaning driving motor, and finally the cleaning driving motor drives the rotating disk to perform intermittent forward and reverse rotation, so as to drive the cleaning liquid and materials in the cleaning cylinder to perform intermittent forward and reverse rotation, and finally improve the cleaning and grinding effects on the materials.

[0012] Furthermore, an overflow port is opened on the outer side wall of the cleaning cylinder, a diversion pipe is arranged on the outer side wall of the cleaning cylinder, and the diversion pipe is used to lead out the cleaning liquid and floating objects flowing out of the overflow port. A guiding part for guiding the floating objects into the overflow port is arranged on the outer side wall of the cleaning cylinder near the top side, and the guiding part includes: Inlet plate, which is arranged on the side wall of the cleaning cylinder and used to guide the floating objects to the overflow port when the cleaning liquid rotates forward. The inlet plate is of a mesh structure; A check valve plate, which is arranged on the side wall of the cleaning cylinder and is used to prevent the floating objects at the overflow port from moving away from the overflow port when the cleaning liquid reverses. The check valve plate is in a mesh structure.

[0013] By adopting the above technical solution, when the cleaning liquid in the cleaning cylinder rotates forward, the floating objects are guided to the overflow port through the guiding plate. When the cleaning liquid in the cleaning cylinder rotates reversely, the check valve plate prevents the floating objects at the overflow port from moving away from the overflow port. At the same time, the mesh structures of the guiding plate and the check valve plate enable the cleaning liquid to pass through normally; finally, the floating objects floating on the cleaning liquid escape from the overflow port along with part of the cleaning liquid, so as to reduce the content of light substances in the material.

[0014] Furthermore, the discharging assembly includes: A turning plate, which is rotatably arranged on the frame. The cleaning cylinder is arranged on the turning plate and rotates with the turning plate to pour out the materials inside it; A turning motor, which is arranged on the frame and is used to drive the turning plate to rotate; A finished product conveyor belt, which is arranged on the frame and is used to discharge the materials poured out by the cleaning cylinder. The finished product conveyor belt adopts a screen structure and is used to filter out small particle substances; A discharging part, which is arranged on the frame and is used to discharge the small particle substances and the cleaning liquid filtered out by the finished product conveyor belt.

[0015] By adopting the above technical solution, after the cleaning cylinder finishes cleaning the materials, the turning motor drives the turning plate to rotate slowly, so as to make the cleaning cylinder turn a certain angle, so that the materials and the cleaning liquid in the cleaning cylinder are poured onto the finished product conveyor belt. The large particle materials are transported away by the finished product conveyor belt with a screen structure, and the small particle sundries and the cleaning liquid pass through the finished product conveyor belt and enter the discharging part and are discharged, so as to complete the separation between the cleaned materials and the sundries.

[0016] Furthermore, a flushing assembly for flushing the materials on the finished product conveyor belt is arranged on the frame. The flushing assembly includes: A leveling frame, which is arranged on the frame. The finished product conveyor belt passes through the leveling frame; A scraper, which is arranged on the leveling frame. The scraper cooperates with the leveling frame to level the materials on the finished product conveyor belt; A spray head, which is arranged on the frame and above the finished product conveyor belt. The spray head is used to spray water flow onto the finished product conveyor belt and wash the impurities adhering to the surface of the materials into the discharging part.

[0017] By adopting the above technical solution, the leveling frame and the scraper cooperate with each other to form a material passing opening for the finished product conveyor belt and the material to pass through. When the finished product conveyor belt drives the material through the material passing opening, the scraper blocks and levels the material with a stacking height higher than the height of the material passing opening, and finally makes the thickness of the material passing through the material passing opening lower than the set value. Then, the material after leveling is rinsed by the spray head to wash the impurities adhering to the surface of the material into the discharge part, reducing the impurity content of the finished product material.

[0018] Further, a drying assembly for drying the material on the finished product conveyor belt is provided on the frame, and the drying assembly includes: A heat insulation frame, which is arranged on the frame and forms a drying chamber for drying the material on the finished product conveyor belt. The distance value between the heat insulation frame and the upper surface of the finished product conveyor belt is equal to the distance value between the scraper and the upper surface of the finished product conveyor belt; A heater, which is arranged in the heat insulation frame and is used for heating and drying the material in the heat insulation chamber.

[0019] By adopting the above technical solution, after the finished product conveyor belt brings the material into the heat insulation frame, the heat insulation chamber is heated by the heater to realize the drying treatment of the material and improve the quality of the material finished product.

[0020] Further, a condensation assembly for condensing and discharging the water vapor in the heat insulation chamber is provided on the heat insulation frame, and the condensation assembly includes: A diversion frame, which is arranged in the heat insulation frame and is used for collecting the condensed water on the diversion frame and the top of the heat insulation frame; A thermoelectric couple condensation plate, which is inlaid on the diversion frame. The heating end of the thermoelectric couple condensation plate is located at one end of the diversion frame close to the finished product conveyor belt, and the condensation end of the thermoelectric couple condensation plate is located at one end of the diversion frame close to the top of the heat insulation frame; A drain pipe, which is arranged on the diversion frame and is used for discharging the accumulated water in the diversion frame out of the heat insulation frame.

[0021] By adopting the above technical solution, the thermoelectric couple condensation plate improves the condensation efficiency of the water vapor on the diversion frame. The diversion frame is used for collecting the condensed water between the diversion frame and the top of the heat insulation frame, and finally the condensed water collected in the diversion frame is discharged through the drain pipe to reduce the probability of the condensed water droplets in the heat insulation chamber falling on the material.

[0022] Further, a plurality of groups of sewage pipes are arranged at intervals on the side wall of the cleaning cylinder near the bottom end. A sewage filter screen that only allows the cleaning liquid and fine particles to pass through is arranged at the end of the sewage pipe close to the cleaning cylinder. The sewage pipe is intermittently opened and is used for discharging the fine particles in the cleaning cylinder.

[0023] By adopting the above technical solution, as the cleaning liquid cleans and grinds the material, more and more small particles are generated in the cleaning cylinder. When the sewage pipe is opened, part of the cleaning liquid and fine particles enter the sewage pipe through the sewage filter screen and are finally discharged from the cleaning cylinder, thereby reducing the content of fine particles in the cleaning cylinder and improving the cleaning and grinding effect of the cleaning liquid on the material.

[0024] Further, a control valve for controlling the opening and closing of the sewage pipe is provided at one end of the sewage pipe away from the cleaning cylinder. A temporary storage cavity for temporarily storing fine particles is formed between the control valve and the sewage filter screen. The sewage pipe is inclined, and the height of the end close to the cleaning cylinder is higher than the height of the end of the control valve.

[0025] By adopting the above technical solution, when the control valve closes the sewage pipe, as the cleaning liquid rotates, the fine particles in the cleaning cylinder enter the temporary storage cavity through the sewage filter screen under the action of gravity and centrifugal force. When the control valve opens the sewage pipe, the fine particles and cleaning liquid in the temporary storage cavity are quickly discharged from the sewage pipe, thereby increasing the speed of discharging fine particles from the sewage pipe and reducing the discharge amount of the cleaning liquid when the sewage pipe discharges fine particles.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The waste concrete is subjected to multi-stage crushing treatment by the crushing mechanism, and the crushed material is temporarily stored by the temporary storage member. Then, a certain amount of the crushed material is discharged into the cleaning cylinder. The cleaning liquid and the material in the cleaning cylinder are driven by the cleaning driving member for cleaning and grinding. The impurities and cleaning liquid washed off are discharged through the discharging assembly, thereby removing the loose particles and weak layers on the surface of the crushed material, and at the same time adjusting the particle size and shape of the material, and finally improving the quality of the waste concrete crushing and recycling finished product.

[0027] 2. The heater and the heat insulation frame cooperate with each other to dry the washed material, thereby reducing the probability of the material being contaminated by fine particles again, and at the same time improving the quality of the material finished product.

Detailed implementation manners

[0030] The following Figure 1-7 further elaborates on the present application in detail.

[0031] The embodiment of the present application discloses a waste recycling and reuse equipment in concrete production.

[0032] Referring to Figure 1 , a waste recycling and reuse equipment in concrete production, including a frame 1, a crushing mechanism 2 for multi-stage crushing of waste concrete is arranged on the frame 1, and a cleaning mechanism 3 for cleaning the materials discharged by the crushing mechanism 2 is arranged on the frame 1.

[0033] Referring to Figure 1 and Figure 2, the frame 1 is fixedly installed on the ground. The crushing mechanism 2 includes a crushing box 21, a primary crusher 22, a first screening member 23, a reflux member 24 and a secondary crusher 25. The top of the crushing box 21 is connected to the feeding conveyor belt, so that the waste concrete is transported into the crushing box 21 through the feeding conveyor belt; the primary crusher 22 is fixedly installed in the crushing box 21, and the primary crushing box 21 is used for primary crushing of the waste concrete entering the crushing box 21; the first screening member 23 is fixedly installed in the crushing box 21 and connected to the primary crusher 22. The waste concrete crushed by the primary crusher 22 enters the first screening member 23, and the materials crushed by the primary crusher 22 are screened into two parts, thick and thin, by the first screening member 23; the reflux member 24 is fixedly installed on the crushing box 21, and the reflux member 24 is connected to the first screening member 23. The reflux member 24 is used to reflux the coarse materials screened by the first screening member 23 onto the feeding conveyor belt; the secondary crusher 25 is connected to the first screening member 23. The first screening member 23 flows the screened fine materials into the secondary crusher 25, and the secondary crusher 25 re-crushes the fine materials discharged by the first screening member 23; in this embodiment, the primary crusher 22 uses a jaw crusher, the secondary crusher 25 uses a hammer crusher, and the first screening member 23 uses a vibrating screen.

[0034] Referring to Figure 1 and Figure 2 , the crushing mechanism 2 further includes a secondary screening conveyor belt 26. The secondary screening conveyor belt 26 is fixedly installed on the frame 1, and the secondary screening conveyor belt 26 is connected to the secondary crusher 25. The secondary screening conveyor belt 26 is used to transport the materials crushed by the secondary crusher out. A plurality of groups of fine screening holes are spaced apart on the secondary screening conveyor belt 26; a guiding member 27 is fixedly installed on the bottom of the secondary screening conveyor. The guiding member 27 is used to collect the fine particles falling from the plurality of groups of fine screening holes and discharge them into the bottom of the crushing box 21; when the secondary screening conveyor belt 26 moves, the materials with a smaller diameter on the secondary screening conveyor belt 26 fall into the guiding member 27 through the plurality of groups of fine screening holes. The guiding member 27 guides the fine particles into the bottom of the crushing box 21, and regularly transports the fine particles at the bottom of the crushing box 21 out, and finally completes the crushing treatment of the waste concrete.

[0035] Referring to Figure 1 , Figure 3 and Figure 4, the cleaning mechanism 3 includes a temporary storage member 31, a cleaning cylinder 32, and a cleaning driving member 33. The temporary storage member 31 is fixed on the frame 1. The temporary storage member 31 is connected to the secondary sieve conveyor belt 26 and is used for temporarily storing the materials transported out on the secondary sieve conveyor belt 26. The cleaning cylinder 32 is arranged on the frame 1 and is located directly below the temporary storage member 31. When the valve in the temporary storage member 31 is opened, the materials in the temporary storage member 31 are discharged into the cleaning cylinder 32. The materials discharged from the temporary storage member 31 are cleaned by the cleaning liquid in the cleaning cylinder 32. The cleaning driving member 33 is arranged on the cleaning cylinder 32 and is used for driving the cleaning liquid and the materials in the cleaning cylinder 32 to rotate, so as to clean the materials. Finally, the microscopic pollutants adhering to the surface of the materials and the loosely attached concrete residues are separated from the materials, thereby improving the cleanliness of the materials and the bonding performance with the new concrete. At the same time, by driving the cleaning liquid and the materials in the cleaning cylinder 32 to rotate through the cleaning driving member 33, the materials interact with each other, and the cleaning liquid interacts with the materials, so as to grind the materials and remove some soft layers and pollutants on the surface of the materials.

[0036] Refer to Figure 3 and Figure 4 , in order to improve the cleaning and grinding effects of the materials in the cleaning cylinder 32, multiple groups of protrusions 321 are installed at intervals on the side wall of the cleaning cylinder 32. Grinding sheets for frictionally grinding the materials are fixedly installed on the protrusions 321. When the cleaning liquid and the materials in the cleaning cylinder 32 rotate, the materials rub against the grinding sheets on the protrusions 321, so as to grind the surface of the materials and improve the grinding effect on the materials. At the same time, multiple groups of water spraying members 322 are arranged at intervals inside the cleaning cylinder 32. The water spraying members 322 are used for spraying high-pressure water flows, and the internal rotating materials are impacted by the high-pressure water flows, thereby improving the cleaning and grinding effects on the materials.

[0037] Refer to Figure 3 and Figure 4 , the cleaning driving member 33 includes a rotating disk 331, a cleaning driving motor 332, and a controller. The rotating disk 331 is rotatably installed on the bottom of the cleaning cylinder 32 and is used for driving the cleaning liquid and the materials in the cleaning cylinder 32 to rotate. Multiple groups of ridges are installed at intervals on the rotating disk 331. When the rotating disk 331 rotates, it is convenient to drive the cleaning liquid and the materials in the cleaning cylinder 32 to rotate through the multiple groups of ridges. The cleaning driving motor 332 is arranged on the outside of the cleaning cylinder 32 and is used for driving the rotating disk 331 to rotate. The controller is fixedly installed on the outside of the cleaning cylinder 32 and is used for controlling the intermittent forward and reverse rotation of the cleaning driving motor 332. By controlling the intermittent forward and reverse rotation of the rotating disk 331 through the controller, the collision between the cleaning liquid and the materials and between the materials is improved, thereby improving the cleaning and grinding effects on the materials.

[0038] Refer to Figure 3 and Figure 4 Since the waste concrete contains a small amount of light substances such as plastics, wood chips and foams, due to the light mass of the light substances, the cleaning liquid and the materials in the cleaning cylinder 32 are driven to rotate by the rotating disk 331, so that the light substances are separated from the materials and float above the cleaning liquid; an overflow port 323 is formed on the outer side wall of the cleaning cylinder 32, and a diversion pipe is fixedly installed on the outer side wall of the cleaning cylinder 32, and the diversion pipe is used to lead out the cleaning liquid and the floating substances flowing out of the overflow port 323. A guiding member 4 for guiding the floating substances into the overflow port 323 is arranged on the outer side wall of the cleaning cylinder 32 near the top side. The guiding member 4 includes a guiding plate 41 and a blocking plate 42. The guiding plate 41 is fixedly installed on the side wall of the cleaning cylinder 32, and the guiding plate 41 is used to guide the floating substances to the area of the overflow port 323 when the cleaning liquid rotates forward. The guiding plate 41 is in a mesh structure; the blocking plate 42 is fixedly installed on the side wall of the cleaning cylinder 32, and the blocking plate 42 is used to prevent the floating substances in the area of the overflow port 323 from moving away from the overflow port 323 when the cleaning liquid rotates in reverse. The blocking plate 42 is in a mesh structure.

[0039] Refer to Figure 3 and Figure 4 Specifically, as the water spraying member 322 continuously sprays high-pressure water flow into the cleaning cylinder 32, the amount of the cleaning liquid in the cleaning cylinder 32 is continuously increased. When the rotating disk 331 of the cleaning cylinder 32 rotates forward, it drives the cleaning liquid to rotate forward, and the floating substances enter the area of the overflow port 323 through the guiding of the guiding plate 41. The cleaning liquid can pass through the guiding plate 41, while the relatively large floating substances cannot pass through the guiding plate 41; when the rotating disk 331 rotates in reverse, it drives the cleaning liquid to rotate in reverse, and the cleaning liquid impacts the guiding plate 41 in the reverse direction, so that the guiding plate 41 maintains good water permeability; at this time, the floating substances flow with the cleaning liquid and impact on the blocking plate 42. The cleaning liquid can pass through the blocking plate 42, while the relatively large floating substances cannot pass through the blocking plate 42, so as to block the floating substances at the overflow port 323 in the area of the overflow port 323; when the rotating disk 331 rotates forward again, the cleaning liquid impacts the blocking plate 42 in the reverse direction, so as to wash the floating substances in the area of the overflow port 323 into the overflow port 323 and discharge them, and finally discharge the relatively large floating substances in the cleaning cylinder 32.

[0040] Refer to Figure 3 and Figure 4 Since the cleaning liquid continuously cleans the materials, the content of fine particles in the cleaning cylinder 32 is continuously increased, which affects the subsequent cleaning and grinding effects of the materials; a plurality of groups of sewage pipes 5 are installed at intervals on the side wall of the cleaning cylinder 32 near the bottom end. A sewage filter screen 51 that only allows the cleaning liquid and fine particles to pass through is arranged at one end of the sewage pipe 5 close to the cleaning cylinder 32. The sewage pipe 5 is intermittently opened to discharge the fine particles in the cleaning cylinder 32.

[0041] Refer to Figure 3 andFigure 4 , to avoid the probability of a large amount of cleaning liquid flowing out of the cleaning cylinder 32 due to the long opening time of the sewage discharge pipe 5, a control valve 52 for controlling the opening and closing of the sewage discharge pipe 5 is fixedly installed at one end of the sewage discharge pipe 5 far from the cleaning cylinder 32. A temporary storage cavity 53 for temporarily storing fine particles is formed between the control valve 52 and the sewage discharge filter screen 51. The sewage discharge pipe 5 is inclined, and the height of the end of the sewage discharge pipe 5 close to the cleaning cylinder 32 is higher than the height of the end of the control valve 52. When the control valve 52 is closed, the fine particles in the cleaning cylinder 32 accumulate in the temporary storage cavity 53 under the action of gravity and centrifugal force, so that the fine particles can be quickly discharged at the first time when the control valve 52 is opened, reducing the probability of a large amount of cleaning liquid being discharged; the generation of fine particles in the cleaning cylinder 32 of this embodiment continuously decreases with the increase of the cleaning time. Therefore, the opening time interval of the control valve 52 continuously increases with the increase of the cleaning duration.

[0042] Refer to Figure 1 , Figure 3 and Figure 5 , the cleaning mechanism 3 further includes a discharging assembly 6. The discharging assembly 6 is arranged on the frame 1 and is used to discharge the materials in the cleaning cylinder 32 after cleaning; the discharging assembly 6 includes a turning plate 61, a turning motor 62, a finished product conveyor belt 63 and a discharging member 64. The turning plate 61 is rotatably installed on the frame 1, and the cleaning cylinder 32 is fixedly installed on the turning plate 61. The cleaning cylinder 32 is turned over with the turning plate 61 to pour out the materials inside; the turning motor 62 is fixedly installed on the frame 1, and the turning motor 62 is used to drive the turning plate 61 to turn over; the finished product conveyor belt is fixedly installed on the frame 1, and the finished product conveyor belt 63 is used to discharge the materials poured out of the cleaning cylinder 32. The finished product conveyor belt 63 adopts a screen structure to filter out small particle substances and cleaning liquid; the discharging member 64 is fixedly installed on the frame 1, and the discharging member 64 is located directly below the finished product conveyor belt 63. The discharging member 64 is used to discharge the small particle substances and cleaning liquid filtered out by the finished product conveyor belt 63.

[0043] Refer to Figure 1 , Figure 3 and Figure 5 , specifically, when the cleaning of the materials in the cleaning cylinder 32 is completed, the turning motor 62 drives the turning plate 61 to slowly rotate, so that the cleaning cylinder 32 is tilted and turned by a certain angle. During this process, the cleaning liquid and materials in the cleaning cylinder 32 slide out of the cleaning cylinder 32 under the action of gravity. When the center line of the cleaning cylinder 32 is tilted downward, the materials in the cleaning cylinder 32 completely slide onto the finished product conveyor belt 63 under the action of gravity and the high-pressure water flow sprayed by the water spraying member 322. At the same time, the cleaning liquid and some fine particles pass through the screen-structured finished product conveyor belt 63 and fall onto the discharging member 64 and are discharged, so as to complete the cleaning of the materials.

[0044] Refer to Figure 5and Figure 6 On the frame 1, a flushing assembly 7 is provided for flushing the materials on the finished product conveyor belt 63. The flushing assembly 7 includes a leveling frame 71, a scraper 72 and a nozzle 73. The leveling frame 71 is fixedly installed on the frame 1, and the finished product conveyor belt 63 passes through the leveling frame 71; the scraper 72 is fixedly installed on the leveling frame 71, and a material passing opening 721 of a specified size is formed between the scraper 72 and the leveling frame 71. When the finished product conveyor belt 63 drives the materials through the material passing opening 721, the scraper 72 blocks and levels the materials with a stacking height higher than the height of the material passing opening 721, and finally makes the thickness of the materials passing through the material passing opening 721 lower than the set value; the nozzle 73 is fixedly installed on the frame 1, the nozzle 73 is located above the finished product conveyor belt 63, and the nozzle 73 is used to spray water flow onto the finished product conveyor belt 63 to wash the impurities adhering to the surface of the materials into the discharging member 64.

[0045] Refer to Figure 1 and Figure 5 Specifically, since the cleaning liquid in the cleaning cylinder 32 and the materials are poured onto the finished product conveyor belt 63 together, some of the separated fine particles will re-adhere to the surface of the materials. At the same time, the materials on the finished product conveyor belt 63 are prone to agglomerate. The scraper 72 levels the materials with too high a stack, making the thickness of the materials on the finished product conveyor belt 63 uniform. Then, water flow is sprayed through the nozzle 73 to wash the impurities re-adhering to the surface of the materials onto the finished product conveyor belt 63. Finally, the fine particles and the water flow enter the discharging member 64 and are discharged, reducing the adhesion probability of the fine particles on the finished product materials.

[0046] Refer to Figure 5 and Figure 6 On the frame 1, a drying assembly 8 is provided for drying the materials on the finished product conveyor belt 63. The drying assembly 8 includes a heat insulation frame 81 and a heater 82. The heat insulation frame 81 is fixedly installed on the frame 1 and forms a drying chamber for drying the materials on the finished product conveyor belt 63. The heat insulation frame 81 has good heat insulation effect. The distances from both ends of the heat insulation frame 81 to the finished product conveyor belt 63 are equal to the distance from the scraper 72 to the finished product conveyor belt 63, thus ensuring the passage of the materials while minimizing the distance value between the heat insulation frame 81 and the upper surface of the materials; the heater 82 is fixedly installed in the heat insulation frame 81, and the heater 82 is used to heat and dry the materials in the heat insulation chamber to remove the moisture inside the materials and further improve the strength and durability of the materials as aggregates; the heater 82 in this embodiment can adopt microwave heating or infrared heating methods.

[0047] Refer to Figure 6 and Figure 7, since a large amount of water vapor is easily generated during the drying process of the material, when the water vapor condenses, it is likely to drip onto the material. Since the temperature of the condensed water is relatively low and the temperature of the dried material is relatively high, the direct dripping of the condensed water onto the dried material is likely to cause damage to the material. Therefore, a condensation component 9 for condensing and discharging the water vapor in the heat insulation cavity is provided in the heat insulation frame 81. The condensation component 9 includes a diversion frame 91, a thermoelectric couple condensation plate 92, and a drain pipe 93. The diversion frame 91 is a hollow conical structure composed of four triangular plates. The diversion frame 91 is fixedly installed on the top of the heat insulation frame 81. There are gaps between the diversion frame 91 and the four side walls of the heat insulation frame 81 to facilitate the entry of water vapor into the top of the heat insulation frame 81 and the inside of the diversion frame 91. The thermoelectric couple condensation plate 92 is inlaid on the diversion frame 91.
