[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagrams.

[0034] Reference Figures 1-10 This is the first embodiment of the present invention, which provides a method for recycling construction waste. This method can effectively crush and screen the waste, and also treat the flue gas generated in the process.

[0035] A large amount of waste is generated during the construction process. This waste is put into a waste recycling device. The waste recycling device is used to fully crush the waste. While the waste is being crushed, the crushing effect is used to achieve vibration screening of the waste. The screened material is discharged from the outlet through a conveyor device and is atomized and dusted by itself.

[0036] The material is crushed by a crushing device, and the eccentric rotating mechanism makes the screen plate vibrate up and down to further screen the waste and obtain finer waste. The eccentric mechanism also makes it possible to periodically spray water mist onto the discharge port to remove dust, so that the dust in the air is adsorbed and falls down by the water mist. The dust removal and the screen plate vibration are carried out simultaneously.

[0037] The method involves first placing the material into the device, where it is processed by the crushing components. Two sets of crushing devices are installed, rotating with sufficient clearance between them to allow for material descent, thus improving crushing efficiency. The crushed material then flows onto a vibrating plate, where continuous vibration disperses fine particles while larger particles are blocked and can be manually removed. The material is then transported out, and the resulting dust is periodically treated by the release of water mist. This periodic water mist not only effectively absorbs the dust but also conserves water resources. Example

[0038] Reference Figures 4-10 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that this embodiment provides a crushing mechanism 100, which can fully crush materials.

[0039] Specifically, the crushing mechanism 100 includes a crushing component 101, a screening component 102 disposed at the bottom of the crushing component 101, and a dust removal component 103 disposed on one side of the screening component 102. The crushing component 101 includes a motor 101a and a rotating shaft 101b connected to one side of the motor 101a. The outer surface of the rotating shaft 101b is provided with a tooth 101b-1 and a drive gear 101b-2. The drive gear 101b-2 is connected to the crushing roller 101c through a driven gear 101c-1.

[0040] Furthermore, the two crushing rollers 101c rotate, thereby ensuring a good material processing effect. The motor 101a drives the rotating shaft 101b to rotate, and then the rotating shaft 101b drives the driven gear 101c-1 to rotate through the driving gear 101b-2. Then the two crushing rollers 101c start to rotate simultaneously.

[0041] The screening component 102 includes a transmission component 102a and a vibration component 102b. The transmission component 102a is connected to the gear 101b-1, and the vibration component 102b is connected to one side of the transmission component 102a. The transmission component 102a includes a transmission belt 102a-1 connected to the gear 101b-1, a transmission gear 102a-2 connected to the transmission belt 102a-1, and a first transmission rod 102a-3 connected inside the transmission gear 102a-2. A first circular block 102a-4 is fixedly connected to one side of the first transmission rod 102a-3, a first long rod 102a-5 is connected to one side of the first circular block 102a-4, a second circular block 102a-6 is provided on one side of the first long rod 102a-5, and a second transmission rod 102a-7 is provided on one side of the second circular block 102a-6.

[0042] Furthermore, the vibrating element 102b includes a connecting rod 102b-2 hinged to the first long rod 102a-5, a top column 103d hinged to the connecting rod 102b-2, a sieve plate 102b-3 disposed on the top of the top column 103d, limit blocks 102b-3a disposed on both sides of the sieve plate 102b-3, and a hole 102b-3b through-hole on one side of the sieve plate 102b-3.

[0043] Preferably, the transmission belt 102a-1 is driven by the gear 101b-1, and then the transmission belt 102a-1 meshes with the transmission gear 102a-2, thereby driving the first transmission rod 102a-3 to rotate. Then, the first transmission rod 102a-3 drives the first circular block 102a-4, the first long rod 102a-5, the second circular block 102a-6, and the second transmission rod 102a-7 to rotate simultaneously. Since the first long rod 102a-5 adopts an eccentric design, it drives the connecting rod 102b-1 and the top column 103d to move back and forth, thereby moving the screen plate 102b-3 up and down, making the screening effect better.

[0044] The dust removal component 103 includes a third circular block 103a disposed on one side of the second transmission rod 102a-7, a second long rod 103b disposed on one side of the third circular block 103a, a fourth circular block 103c disposed on one side of the second long rod 103b, a top rod 103d hinged to the second long rod 103b, the top rod 103d having two sections connected by a hinge, a guide member 103e sleeved on the outer surface of the top rod 103d, a water inlet 103e-1 opened on one side of the guide member 103e, and an atomizing nozzle 103f disposed on one side of the guide member 103e.

[0045] Preferably, the third circular block 103a, the second long rod 103b, and the fourth circular block 103c are driven to rotate by the second transmission rod 102a-7, which in turn drives the push rod 103d to move back and forth in the guide member 103e, periodically pushing the water in the guide member 103e. The push rod 103d can also intermittently close or open the water inlet 103e-1, so that after each water push, the push rod 103d retracts, and the water flows into the guide member 103e through the water inlet 103e-1, thus preparing for the next water push. Example

[0046] Reference Figures 1-10 This is the third embodiment of the present invention, which is based on the previous two embodiments: This embodiment provides a device for recycling and utilizing construction waste.

[0047] Specifically, the containing mechanism 200 includes a box 201 disposed on one side of the crushing component 101, a sealing element 202 disposed on one side of the box 201, and a transport component 203 disposed at the bottom of the box 201.

[0048] The housing 201 includes a feed inlet 201a, a water tank 201b, a cleaning port 201c, a guide block 201d, and a processing port 201e. The feed inlet 201a is located at the top of the housing 201, the water tank 201b is located on one side of the housing 201, the cleaning port 201c is located on one side of the housing 201, the guide block 201d is located inside the housing 201, and the processing port 201e is located at the bottom of one side of the housing 201.

[0049] The sealing component 202 includes a limiting frame 202a disposed on one side of the cleaning port 201c. A limiting groove 202a-1 is formed inside the limiting frame 202a. A sealing plate 202b is slidably connected inside the limiting groove 202a-1. A handle 202b-1 is provided on the top of the sealing plate 202b. The transport component 203 includes a rotating gear 203a and a transport belt 203b. The rotating gear 203a and the transport belt 203b are meshed together.

[0050] When using this device, the operator first turns on the motor 101a and puts the material into the feed inlet 201a. The motor 101a drives the rotating shaft 101b to rotate. The surface of the rotating shaft 101b is equipped with teeth 101b-1 and a driving gear 101b-2. Through the meshing of the driving gear 101b-2 and the driven gear 101c-1, the rotating shaft drives the two crushing rollers 101c to rotate in the same direction. There is sufficient clearance between the two sets of crushing rollers 101c to allow the material to fall, thus achieving the crushing of the material. Furthermore, the teeth 101b-1 mesh with the transmission belt 102a-1, and the transmission belt 102a-1 meshes with the transmission gear 102a-2, thereby driving the material... The rotation of the first transmission rod 102a-3, the first circular block 102a-4, the first long rod 102a-5, the second circular block 102a-6, and the second transmission rod 102a-7, in turn, drives the connecting rod 102b-1 and the top column 103d to reciprocate, thereby achieving the up-and-down vibration of the screen plate 102b-3, further screening the material. The limiting block 102b-3a and the guide block 201d also limit the movement of the screen plate 102b-3, and guide the material. Furthermore, the rotation of the third circular block 103a, the second long rod 103b, and the fourth circular block 103c causes the top rod 103... The nozzle d is driven to reciprocate, thus periodically reciprocating within the guide member 103e and periodically pushing the water within it. The push rod 103d can also intermittently close or open the inlet 103e-1, so that after each water push, the push rod 103d retracts, and the water flows back into the guide member 103e through the inlet 103e-1, preparing for the next water push. This ensures that for each vibration of the screen plate 102b-3, the atomizing nozzle 103f synchronously sprays water mist once. To achieve both effective adsorption of airborne dust and water conservation, the vibrating material allows small particles to fall through holes 102b-3b into the conveyor belt 203b for transport, while larger particles remain on the sieve plate 102b-3. At this point, the sealing plate 202b is removed from the limiting groove 202a-1, thereby cleaning the large particles on the sieve plate 102b-3. The atomizing nozzle 103f can be a nozzle that requires a certain pressure to extrude, or a one-way valve can be installed on one side of the atomizing nozzle 103f.

[0051] Preferably, when the material is being crushed by the crushing roller 101c, the crushed material will continue to fall onto the screen plate 102b-3, where it will accumulate and begin to be screened by the vibration of the screen plate 102b-3. Small particles will fall to the next layer through the holes 102b-3b, while large particles will remain on the screen plate 102b-3. At this time, the screen plate 102b-3 and the crushing roller 101c will continue to operate simultaneously.

[0052] When the waste material on the sieve plate 102b-3 accumulates to a certain level, it will push the pusher 204a to move. This causes the pusher 204a and the push rod 204a-1 to move and compress the spring 204b. Since the push rod 204a-1 is Y-shaped, its top limits the movement of the two driven gears 101c-1. Each driven gear 101c-1 is equipped with a flat key, and the shafts of the two driven gears 101c-1 are provided with guide grooves. Thus, the push rod 204a-1 drives the two driven gears 101c-1 to move along the guide grooves. This causes the two driven gears 101c-1 to disengage from the driving gear 101b-2, allowing the crushing roller 101c to idle, thus stopping the material from being crushed by the crushing roller 101c and preventing it from falling onto the screen plate 102b-3. Driven by the motor, the screen plate 102b-3 continues to operate, thus continuously processing the compressed material. When the material decreases, under the action of the spring 204b, the push rod 204a-1 drives the two driven gears 101c-1 to move to the position where they mesh with the driving gear 101b-2, so that the crushing roller 101c continues to operate.

[0053] If large particles continue to accumulate on the screen plate 102b-3, the crushing roller 101c will remain idle under the action of the moving part 204. At this time, the operator can first turn off the motor and then clean out the large particles through the cleaning port 201c. The push rod 204a-1 and the driven gear 101c-1 adopt spherical contact to reduce friction.

[0054] The driven gear 101c-1 and the driving gear 101b-2 used in this embodiment are gears from a gearbox. Since this technology is already very mature, it will not be described further in this invention.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
