Description

Technical Field

[0001] The present invention relates to the technical field of solid waste treatment, in particular to a solid waste classification treatment device. Background Art

[0002] With the rapid development of society, the process of industrialization and urbanization is accelerating. Large-scale infrastructure construction requires a large amount of concrete, and the amount of waste concrete is also increasing. At present, the resource processing of recycled building materials and aggregates faces two major problems: on the one hand, waste concrete is difficult to directly use for infrastructure construction; on the other hand, waste concrete has nowhere to be placed, which will occupy a large amount of land resources and cause serious pollution to shallow surface soil and water resources. Therefore, it is necessary to crush the waste concrete by using solid waste treatment equipment;

[0003] However, the existing solid waste treatment device still has the following technical problems when in use:

[0004] (1) Since there are still a few metal reinforcements in the current waste concrete, after the waste concrete is crushed by the solid waste treatment device, it is impossible to automatically sort the metal parts from the waste concrete. Instead, the metal parts in the concrete particles need to be manually picked out, which is very troublesome.

[0005] (2) During the screening process of metal parts and concrete particles, some dust or gravel will clog the screening plate, thereby affecting the screening effect of the crushed concrete. The current processing device cannot automatically clear the sieve holes of the screening plate, thereby affecting the screening efficiency.

The left end of the adjusting mechanism is fixed with a placement plate 18, and the upper side wall of the placement plate 18 is provided with a sewage collection box 19. The rear end of the sewage collection box 19 is provided with a metal parts storage box 20. When the metal parts need to be poured out, the position of the metal parts storage box 20 needs to be adjusted to be located at the lower end of the screening groove 5. When the screening groove 5 needs to be cleaned, the position of the sewage collection box 19 needs to be adjusted to be located at the lower end of the screening groove 5.

[0035] The crushing mechanism includes a first rotating rod 21 and a second rotating rod 22. The first rotating rod 21 and the second rotating rod 22 are both arranged to rotate horizontally inside the crushing box 2. The first rotating rod 21 is arranged at the left end of the second rotating rod 22. The rod walls of the first rotating rod 21 and the second rotating rod 22 are both provided with crushing rollers 23. The rear end of the crushing box 2 is located at the rear end of the first rotating rod 21 and is fixed with a first motor 24. The output end of the first motor 24 is fixedly connected to the rear end of the first rotating rod 21. The rod wall of the first rotating rod 21 is sleeved with a first gear 25, and the rear end of the rod wall of the second rotating rod 22 is sleeved with a second gear 26. The first gear 25 and the second gear 26 are engaged.

[0036] An end cover 27 is provided at the upper end of the crushing box 2, and a guide plate 28 is provided obliquely on the inner wall of the crushing box 2 at the upper end of the two crushing rollers 23. The end cover 27 is used to prevent concrete blocks inside the crushing box 2 from popping out and injuring people during the crushing process. The two guide plates 28 can ensure that the concrete blocks can contact the middle position of the two crushing rollers 23 during the downward movement, thereby increasing the crushing effect.

[0037] The transmission mechanism includes a bracket 37, the front wall of the bracket 37 is fixedly connected to the front end of the inner wall of the processing box 1, and the left and right ends of the inside of the bracket 37 are rotatably provided with transmission rollers 38. The rear ends of the two transmission rollers 38 pass through the rear wall of the bracket 37 and extend to the rear end and are sleeved with a first pulley. Evenly arranged support rollers 39 are provided between the two transmission rollers 38. The front and rear ends of the evenly arranged support rollers 39 are rotatably connected to the inner wall of the bracket 37. The rear wall of the bracket 37 is fixed with a fourth motor 40 through a fixed frame, and a transmission rod 41 is fixed to the output end of the fourth motor 40. The rod wall of the transmission rod 41 is sleeved with a symmetrical second pulley. The two first pulleys are connected to the bracket 37 through a belt. The two second pulleys are connected in rotation, and a conveyor belt 42 is provided on the outside of the two transmission rollers 38 and the evenly arranged support rollers 39.

The front and rear ends of the conveyor belt 42 need to contact the inner wall of the bracket 37 to minimize the gap between the conveyor belt 42 and the bracket 37 to avoid the accumulated concrete powder from escaping from the gap.

[0038] A dust absorption box 46 is fixed to the upper end of the right wall of the processing box 1, a water supply pipe 47 is fixed to the right end of the upper side wall of the dust absorption box 46, a sewage pipe 48 is fixed to the lower end of the right wall of the dust absorption box 46, a dust inlet pipe 49 is fixed to the left end of the upper side wall of the dust absorption box 46, and a mounting pipe 50 is fixed to the upper end of the right wall of the processing box 1. The upper end of the dust inlet pipe 49 is fixedly connected to the right wall of the mounting pipe 50, and an exhaust fan 51 is fixed inside the mounting pipe 50. In the process of crushing concrete blocks or screening concrete powder, a small amount of dust is inevitably generated. At this time, the exhaust fan 51 is started to discharge the airflow mixed with dust inside the processing box 1 into the interior of the dust absorption box 46 through the dust inlet pipe 49, thereby preventing dust from overflowing into the air and causing air pollution.

[0039] A support plate 52 is fixed to the rear side of the inner wall of the processing box 1, and the upper side wall of the support plate 52 is in contact with the lower side wall of the fixed frame 3. During the screening process, since the interior of the screening trough 5 is filled with concrete powder and metal parts, in order to avoid damage to the connected transmission rod 36 caused by the large gravity, part of the gravity is borne by the support plate 52 during the screening process.

[0040] Symmetrical mounting brackets are fixed to the lower side walls of the processing box 1 , and shock-absorbing pads are fixed to the lower side walls of the two mounting brackets.

[0041] Working principle:

[0042] During use, a large amount of waste concrete is poured into the crushing box 2, and the end cover 27 at the upper end is engaged to ensure that the crushed stones will not pop out when the waste concrete is crushed. The first motor 24 is started, and the first motor 24 drives the first rotating rod 21 at the output end to rotate. The first rotating rod 21 drives the first gear 25 of the rod wall to rotate, and the first gear 25 drives the meshed second gear 26 to rotate, and the second gear 26 drives the second rotating rod 22 to rotate, so that the first rotating rod 21 and the second rotating rod 22 drive the two crushing rollers 23 to rotate in opposite directions, thereby crushing the concrete blocks. The crushed concrete blocks will become powder and fall into the interior of the screening slot 5, and the metal parts mixed in the concrete blocks will also fall into the interior of the screening slot 5 after being squeezed;

[0043] Through the operation of the two vibration motors 7 and due to the instability of the support spring 4, the screening trough 5 can continuously shake, screening the metal parts and concrete powder inside. The concrete powder passes through the discharge guard plate 8 and falls on the upper end of the transmission mechanism. It is then transported by the transmission mechanism to the interior of the concrete powder collection bucket 10 for centralized collection.

[0044] The first sealing door 11 is opened and the second motor 31 is started. The second motor 31 drives the screw rod 30 at the output end to rotate. The screw rod 30 drives the moving block 32 threadedly connected to the rod wall to move leftward. The moving block 32 drives the fixed rod 33 on the front wall and the fixed frame 3 at the left end to move leftward and move to the left end of the processing box 1. The third motor 35 is started. The third motor 35 drives the transmission rod 36 at the output end to rotate. The transmission rod 36 drives the fixed frame 3 and the screening trough 5 to rotate, and the metal parts collected inside are poured into the metal part storage box 20. At this time, if the sieve holes of the screening plate 6 are blocked by concrete powder or fine concrete particles, the water pump 15 can be started. The water pump 15 discharges the water inside the water tank 14 through the vertical pipe 16 and the high-pressure nozzle 17, thereby flushing the screening plate 6. Before flushing, it is necessary to start the hydraulic rod 44. The hydraulic rod 44 drives the adjustment block 45 to move. The adjustment block 45 drives the placement plate 18 on the left wall to move. The placement plate 18 drives the sewage collection box 19 to move and is located directly below the screening trough 5.

[0045] During the screening and crushing process, some concrete powder is inevitably generated. At this time, the exhaust fan 51 needs to be started. Since the processing box 1 is not completely sealed, the air flow mixed with dust inside will enter the dust absorption box 46 through the dust inlet pipe 49. Since the dust absorption box 46 is filled with water, it will mix with the dust, effectively preventing a large amount of dust from overflowing and polluting the air environment.
