Description

Technical Field

[0001] This invention relates to the field of construction waste treatment technology, specifically to a construction waste treatment device for green building construction. Background Technology

[0002] When processing waste from walls and floors, the crushed concrete can be used as recycled aggregate in new building materials and even in road construction. During the crushing process, magnetic separation can recover the internal reinforcing steel bars, which are then sent to metal recycling companies for processing. Currently, after magnetic separation, the reinforcing steel bars are piled together. However, due to their high hardness and flexible structure, the piles are loose and difficult to store and transport, requiring secondary processing. This secondary processing involves rearranging, handling, bundling, and compressing the already piled-up reinforcing steel bars. This not only requires additional time but also reduces overall processing efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a construction waste treatment device for green building construction, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a construction waste treatment device for green building construction, comprising:

[0006] Conveyor 3 is located at one end of conveyor 1 and is arranged perpendicular to the length direction of conveyor 1. A large piece crushing section corresponding to the screening trough is fixedly connected to the middle of conveyor 3. The large piece crushing section includes a fixed plate located below the end of the movable pressure plate. The bottom of the inner wall of the fixed plate is slidably connected to the movable pressure plate, which is used to crush large pieces of material and guide the material.

[0007] Conveyor 2 is placed upside down above conveyor 1 and perpendicular to conveyor 1. A permanent magnet is fixed inside conveyor 2 in the middle of the conveyor belt.

[0008] An extrusion box is located at the bottom of conveyor one. One end of conveyor two is connected to the extrusion box via a guide chute. An extrusion plate two and an extrusion plate one for pressing iron into shape and temporarily storing materials are slidably connected inside the extrusion box. An iron outlet is opened on one side of the extrusion box corresponding to the extrusion plate two. A sealing plate is slidably arranged on the outside of the iron outlet. A top rod is fixedly connected to the top of the extrusion plate one. When the extrusion plate one moves forward, the top rod drives the movable pressure plate to crush the material. When the extrusion plate one resets, the top rod drives the sealing plate to be misaligned with the iron outlet.

[0009] Preferably, a dust cover is fixedly connected to the top of conveyor one, and spray pipes are fixedly connected to both sides of the top of conveyor two and both sides of the top of conveyor three to reduce dust pollution to the atmosphere.

[0010] Preferably, metal blocks are fixed to both sides of one end of the conveyor, and a limit rod is vertically slidably connected to the inner side of the middle of the metal block. A lifting plate is fixedly connected to the top of the limit rod, and the lifting plate is fixedly connected to the inner wall of the screening trough. A spring is sleeved on the outer side of the limit rod and between the lifting plate and the metal block. A deflecting wheel is fixedly connected to the end of the conveyor roller at one end of the conveyor, and the outer side of the deflecting wheel is slidably connected to the lifting plate.

[0011] Preferably, a support plate is fixedly connected to the middle of the conveyor three, and a fixing plate is fixedly connected to one side of the support plate. The fixing plate is located below one end of the screening trough. Through holes are opened on the side and bottom of the fixing plate. Multiple triangular plates are fixedly connected at equal intervals inside the fixing plate to one side corresponding to the movable pressure plate.

[0012] Preferably, a fixed baffle is fixedly connected to one end of the bottom of the fixed plate, and a limiting rod is slidably connected to the middle of the fixed baffle. One end of the limiting rod is fixedly connected to the movable pressure plate, and a spring for driving the limiting rod to reset is sleeved on the outside of the limiting rod. Two rectangular holes corresponding to the top rod are opened in the middle of the fixed baffle.

[0013] Preferably, a hydraulic cylinder is fixedly connected to one end of the extrusion box, the output end of the extrusion plate is fixedly connected to the extrusion plate, the extrusion plate has an L-shaped structure and is slidably connected to the extrusion box, and a sliding blade is fixedly connected to one end inside the extrusion box, with the bottom of the sliding blade slidably connected to the top of the extrusion plate.

[0014] Preferably, a hydraulic cylinder two is fixedly connected to one side of the extrusion box and the position of the corresponding slitting blade. The extrusion plate two is fixedly connected to the output end of the hydraulic cylinder two. A limit post is fixedly connected to the side of the extrusion box away from the hydraulic cylinder two. A limit rod three is slidably connected to the middle of the limit post. The end of the limit rod three is fixedly connected to the sealing plate. A spring three is sleeved on the outside of the limit rod three and between the limit post and the sealing plate. A limit switch is fixedly connected to one end of the sealing plate.

[0015] Preferably, a liquid-solid connection unloading block is fixedly connected to one side of the top rod, and one end of the bottom side of the fixed connection unloading block has an angled structure. A limit rod four is fixedly connected to one side of the sealing plate, and a spring four for driving the lifting block to move upward is sleeved on the outer side of the limit rod four. A lifting block is slidably connected to the top of the limit rod four, and the top of the lifting block has an inclined surface parallel to the angled structure of the fixed connection unloading block.

[0016] Preferably, the lifting inclined block is fixedly connected to a guide plate, one end of which has an inclined guide groove, and one end of the extrusion box is fixedly connected to a fixing rod corresponding to the opening of the guide groove. When the guide groove slides outside the fixing rod, the lifting inclined block moves downward.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: When conveyor one conveys the crushed material, the permanent magnet can attract the steel bars in the material, causing them to adhere to the conveyor belt of conveyor two and move with the conveyor belt in a direction offset from conveyor one, thus achieving initial separation of the steel bars from the material. After the steel bars are conveyed to the end of the permanent magnet, they fall into the guide chute under gravity and slide into the extrusion box. The extrusion plate two then extrudes the steel bars at the front end of the extrusion plate one again, realizing automatic compression processing of the sorted steel bars, which facilitates transportation and storage. When the steel bars are extruded and formed, the top rod, through linkage, causes the movable pressure plate to crush the large particles screened in front, thereby avoiding uneven crushing of particles. The top of conveyor one is fixed with a dust cover, which can effectively prevent the dust generated during material crushing and conveying from spreading into the atmosphere, reducing dust pollution. The spray from the spray pipe can generate humid air during material conveying, helping to capture and settle dust, reducing its impact on the atmospheric environment. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-11The present invention provides a technical solution: a construction waste treatment device for green building construction, comprising: a conveyor 1 with a crusher 3 installed on one side of the top, two crushing rollers inside the crusher 3, a gear fixedly connected to one end of each crushing roller, the two gears meshing and connecting, and a motor fixedly connected to one side of the crusher 3. The motor is connected to one of the crushing rollers via a reducer and a transmission belt assembly. A screening trough 9 with one end inclined downwards is provided at the end of the conveyor 1. Multiple screening holes are opened at the bottom of the screening trough 9. The transmission roller at the end of the conveyor 1 is connected to the screening trough 9 via a deflector wheel 10. The conveyor 3 15 is located at one end of the conveyor 1 and is set perpendicular to the length of the conveyor 1. A large-piece crushing section corresponding to the screening trough 9 is fixedly connected to the middle of the conveyor 3 15. The large-piece crushing section includes a fixed plate 17 located below the end of the movable pressure plate 19. The movable pressure plate 19 is slidably connected to the bottom of the inner wall of the fixed plate 17. The top of the movable pressure plate 19 is a sloping structure, and the inclination angle of its sloping surface is parallel to the bottom of the screening trough 9. It is used to crush large pieces of material and guide the material. The conveyor 2 5 is inverted and fixed above the conveyor 1 and is set perpendicular to the conveyor 1. Multiple rubber plates are equidistantly fixed to the outer side of the conveyor belt of conveyor 25. A permanent magnet 7 is fixed inside conveyor 25, located in the middle of the conveyor belt. The permanent magnet 7 is fixed to the inner wall of the conveyor 25 housing. The length of the permanent magnet 7 is greater than the width of conveyor 1 and less than the length of conveyor 25. An extrusion box 23 is fixed to the bottom of conveyor 1. One end of conveyor 25 is connected to the extrusion box 23 via a guide chute 8. An extrusion plate 27 and an extrusion plate 24 for pressing iron into shape and temporarily storing materials are slidably connected inside the extrusion box 23. The extrusion box 23 has an iron outlet on one side corresponding to the extrusion plate 37. An L-shaped limiting groove is fixed to one side of the top and bottom of the iron outlet. The sealing plate 27 is slidably set inside the L-shaped limiting groove. A top rod 36 is fixedly connected to the top of the extrusion plate 24. A limiting ring that is slidably connected to the top rod 36 is fixed to the top of one end of the extrusion box 23. When the extrusion plate 24 moves forward, the top rod 36 drives the movable pressure plate 19 to crush the material. When the extrusion plate 24 resets, the top rod 36 drives the sealing plate 27 to be misaligned with the iron outlet.

[0032] It should be noted that this embodiment includes a controller and corresponding operating switches. Conveyor 1, Conveyor 2 5, and Conveyor 3 15 are all belt conveyors. A forklift or similar equipment places the wall or floor slab inside the crusher 3. The motor drives the crushing rollers to move towards the center, thus crushing the wall or floor slab. The crushed wall or floor slab enters the interior of Conveyor 1, which then conveys it forward. When passing Conveyor 2 5, under the attraction of the permanent magnet 7, the ferrous metal at the top of Conveyor 1 is attracted to the conveyor of Conveyor 2 5. The conveyor belt of conveyor 25 moves in a direction offset from conveyor 1. When the ferrous metal is conveyed to the end of permanent magnet 7, it falls into guide chute 8 and slides into extrusion box 23 under the action of gravity. After iron removal, the material enters screening trough 9. Under the extrusion of deflector wheel 10 at one end of conveyor 1, screening trough 9 vibrates up and down, so that small pieces of material enter conveyor 315 through the through hole of screening trough 9 and are conveyed forward. A small amount of large pieces of material rolls down into the fixed plate 17 through screening trough 9. Under the action of timer, controller controls hydraulic cylinder 25 to drive extrusion plate 24 to press against the material. The ferrous metal inside the extrusion box 23 is extruded. During the forward movement of the extrusion plate 24, the reinforcing bar falls above it. When the extrusion plate 24 resets, it falls back into the extrusion box 23. The forward movement of the extrusion plate 24 drives the hydraulic cylinder 26 forward, which, through the push rod 36, extrudes the movable pressure plate 19, crushing the blocky material falling in front of it. The extrusion plate 24 stops when it reaches the designated position according to the corresponding limit switch. The extrusion plate 27 then moves to one end, further extruding the reinforcing bar at the front end of the extrusion plate 24. When the material reaches the middle position, under the action of the corresponding limit switch, the controller controls the extrusion plate 24 to reset. The extrusion plate 24 drives the top rod 36 to reset, and the movable pressure plate 19 also resets under the elastic force. As large pieces of material continue to enter the fixed plate 17, they generate vibration. The crushed material enters the conveyor 15 from the bottom and side of the fixed plate 17 and collides with it. During the reset process of the extrusion plate 24, it drives the sealing plate 27 to open. At this time, the extrusion plate 37 pushes out the compressed metal block, allowing the sealing plate 27 to automatically reset after it is released from the restriction. This cycle is repeated to realize the automatic crushing of sorted steel bars, which facilitates their transportation and storage.

[0033] In one embodiment, a dust cover 2 is fixedly connected to the top of conveyor 1, and spray pipes 6 are fixedly connected to both sides of the top of conveyor 2 and both sides of the top of conveyor 3 15. The spray pipes 6 are connected to a water pump through pipes to reduce dust pollution to the atmosphere.

[0034] It should be noted that in this embodiment, the dust cover 2 is placed on top of the conveyor 1 to prevent the dust cover 2 from being crushed and the dust from being dispersed into the atmosphere during the conveying process of the conveyor 1. The water stored by the water pump is sprayed around the conveyor 2 5 and the conveyor 3 15 through the spray pipe 6. The spray can generate humid air during the material conveying process, which helps to capture and settle dust and reduce its impact on the atmospheric environment. The spray pipe 6 corresponds to the position of the fixed plate 17, and its water mist landing point is on the outside of the fixed plate 17.

[0035] In one embodiment, metal blocks are fixed to both sides of one end of the conveyor 1. A limit rod 14 is vertically slidably connected to the inner side of the middle of the metal block. A lifting plate 11 is fixedly connected to the top of the limit rod 14. The lifting plate 11 is fixedly connected to the inner wall of the screening trough 9. A spring 13 is sleeved on the outer side of the limit rod 14 and between the lifting plate 11 and the metal block. A deflector wheel 10 is fixedly connected to the end of the conveyor roller at one end of the conveyor 1. The outer side of the deflector wheel 10 is slidably connected to the lifting plate 11.

[0036] It should be noted that, in this embodiment, during the conveying process of conveyor 1, the conveying roller at its end drives two deflecting wheels 10 to rotate. With the support of spring 13 on lifting plate 11, the screening trough 9 can compress spring 13 up and down. When the deflecting wheel 10 is off-center and close to center respectively contacts lifting plate 11, lifting plate 11 drives limit rod 14 to slide in the middle of metal block. Combined with the elastic force of spring 13, screening trough 9 can reciprocate up and down, thereby screening the material at the top of screening trough 9. Because one end of screening trough 9 is inclined downward, small particles fall through the screen holes onto conveyor 15, while large pieces of material roll into fixed plate 17.

[0037] In one embodiment, a support plate 16 is fixedly connected to the middle of the conveyor 15, a fixed plate 17 is fixedly connected to one side of the support plate 16, and a vibration motor is also installed on one side of the fixed plate 17. The fixed plate 17 is located below one end of the screening trough 9. Through holes are opened on the side and bottom of the fixed plate 17. Multiple triangular plates 18 are fixedly fixed at equal intervals inside the fixed plate 17 corresponding to one side of the movable pressure plate 19. A fixed baffle 20 is fixedly connected to one end of the bottom of the fixed plate 17. A limit rod 21 is slidably connected to the middle of the fixed baffle 20. One end of the limit rod 21 is fixedly connected to the movable pressure plate 19. A spring 22 for driving the limit rod 21 to reset is sleeved on the outside of the limit rod 21. Two rectangular holes corresponding to the top rod 36 are opened in the middle of the fixed baffle 20.

[0038] It should be noted that in this embodiment, large pieces of material impact the fixed plate 17 during the rolling process, and their collision with the triangular plate 18 can cut them. When the extrusion plate 24 drives the top rod 36 to move forward, the top rod 36 contacts the movable pressure plate 19 through the rectangular hole. The top rod 36 drives the movable pressure plate 19 to extrude the material in front, so that the material is crushed by the triangular plate 18. At this time, the limiting rod 21 compresses the spring 22. When the movable pressure plate 19 moves forward, large pieces of material roll from the inclined surface at the top of the movable pressure plate 19 into the fixed plate 17. When the top rod 36 separates from the movable pressure plate 19, the spring 22 drives one end of the limiting rod 21 to move, so that the limiting rod 21 drives the movable pressure plate 19 to reset. The crushed material enters the conveyor 3 15 through the fixed plate 17.

[0039] In one embodiment, a hydraulic cylinder 25 is fixedly connected to one end of the extrusion box 23, and the output end of the extrusion plate 24 is fixedly connected to the extrusion plate 24. The extrusion plate 24 has an L-shaped structure and is slidably connected to the extrusion box 23. A slitting blade 4 is fixedly connected to one end inside the extrusion box 23. The slitting blade 4 is slidably connected to the extrusion plate 24, and the bottom of the slitting blade 4 is slidably connected to the top of the extrusion plate 24. A hydraulic cylinder 26 is fixedly connected to one side of the extrusion box 23 at the position corresponding to the slitting blade 4. An extrusion plate 37 is fixedly connected to the output end of the hydraulic cylinder 26. A limit post is fixedly connected to the side of the extrusion box 23 away from the hydraulic cylinder 26, and the middle of the limit post is slidably connected to a limit post. Position rod 3 28, the end of which is fixedly connected to sealing plate 27. Spring 3 29 is sleeved on the outside of position rod 3 28 and between position rod and sealing plate 27. Limit switch 34 is fixedly connected to one end of sealing plate 27. Hydraulic unloading block 35 is fixedly connected to one side of top rod 36. One end of the bottom side of unloading block 35 is angled. Position rod 4 32 is fixedly connected to one side of sealing plate 27. Spring 4 33 is sleeved on the outside of position rod 4 32 to drive lifting block 30 to move upward. Lifting block 30 is slidably connected to the top of position rod 4 32. The top of lifting block 30 has an inclined surface parallel to the angled structure of unloading block 35.

[0040] It should be noted that in this embodiment, both hydraulic cylinder 25 and hydraulic cylinder 26 are hydraulic cylinders equipped with linear displacement sensors. Under the action of the timer, the controller controls hydraulic cylinder 25 to work at regular intervals. When hydraulic cylinder 25 is working, it drives the extrusion plate 24 to move forward, thereby pushing the steel bar in front of the extrusion plate 24 forward. When a steel bar is placed above the top of the extrusion plate 24, it is cut off under the extrusion action of the extrusion plate 24 and the cutting blade 4, so that it falls above the extrusion plate 24. During the movement of the extrusion plate 24, it drives the push rod 36 to move forward, so that it works in conjunction with the movable pressure plate 19. When the push rod 36 drives the fixed unloading inclined block 35 to cooperate with the lifting inclined block 30, under the close pressing cooperation of the two inclined surfaces, the lifting inclined block 30 moves downward and separates from the fixed unloading inclined block 35. The hydraulic cylinder 25 pushes the extrusion plate 24 to the designated position and then stops working. At this time, the side of the extrusion plate 37 corresponds to the front end of the extrusion plate 24. The controller controls the hydraulic cylinder 26 to drive the extrusion plate 37 forward. At this time, the steel bar is compressed in the closed space formed by the sealing plate 27, the cutting blade 4, the extrusion plate 24, and the extrusion plate 37. When the piston rod of the hydraulic cylinder 26 extends halfway, under the feedback of the linear displacement sensor, the controller controls the hydraulic cylinder 26 to stop working and controls the hydraulic cylinder 25 to drive the extrusion plate 24 to reset. During the resetting process of the extrusion plate 24 driving the top rod 36, the hydraulic cylinder 25 cooperates with the lifting inclined block 30 on the top of the sealing plate 27, thereby pushing the sealing plate 27 along the length direction of the limiting rod 28 through the fixed baffle 20, so that the limiting rod 28 separates from the iron removal port. When the limit switch 34 at one end of the sealing plate 27 contacts the side of the L-shaped limiting groove, the sealing plate 27 is separated from the iron removal port. At this time, the controller controls the hydraulic cylinder 26 to quickly drive the extrusion plate 37 to push the material out of the iron outlet and then quickly reset. The compressed iron block falls onto the corresponding conveying mechanism below. At this time, the hydraulic cylinder 25 continues to drive the sealing plate 27 to move through the extrusion plate 24 and the fixed unloading inclined block 35, and compresses the spring 29.

[0041] In one embodiment, the lifting inclined block 30 is fixedly connected to a guide plate 12, one end of which has an inclined guide groove 31. One end of the extrusion box 23 is fixedly connected to a fixing rod 38 corresponding to the opening of the guide groove 31. When the guide groove 31 slides outside the fixing rod 38, the lifting inclined block 30 moves downward.

[0042] It should be noted that in this embodiment, when the lifting inclined block 30 at one end of the sealing plate 27 drives the limiting rod 21 to contact the fixed rod 38, the opening of the guide groove 31 is at the same height as the fixed rod 38, causing the guide groove 31 to slide along the outside of the fixed rod 38. Therefore, the guide groove 31 is inclined upward in the direction away from the opening, so that the fixed rod 38 presses the bottom of the inner wall of the guide groove 31, causing the lifting inclined block 30 to move downward along the limiting rod 32 and press the spring 33. When the lifting inclined block 30 separates downward from the fixed unloading inclined block 35, under the elastic force of the spring 29, the sealing plate 27 drives the limiting rod 28 to quickly return to its original position, and the sealing plate 27 seals the iron removal port again. This cycle repeats, and the sealing plate 27 automatically opens and closes.
