[0014] The method for using the above-mentioned construction waste classification and processing device is characterized by comprising the following steps:

[0015] Step 1: First, set the speed of drive motor 1, drive motor 2, servo motor 1, servo motor 2, and servo motor 3 through the controller, and set the liquid level threshold measured by the liquid level sensor;

[0016] Step 2: Start the drive motor 1, servo motor 1, servo motor 2, and servo motor 3, and put the construction waste to be crushed into the feeding bin. Under the action of the servo motor 1, the crushing roller will crush the waste, and the crushed waste will fall onto the conveyor belt 1. As the conveyor belt 1 rotates, the waste is pushed forward;

[0017] Driven by servo motor 2, conveyor chain 2 rotates. After the transmission gear in the adsorption component engages with rack 1, the rotating rod rotates, and the electromagnetic rod stirs the material on conveyor belt 1. In addition, when the contact switch on the transmission gear is touched by rack 1, the electromagnetic rod is energized. After the contact switch is triggered, the electromagnetic rod is energized, and the electromagnetic rod adsorbs the metal materials in the slag. When the contact switch on the transmission gear touches rack 2, the electromagnetic rod is de-energized, and the metal materials fall onto conveyor chain 2, and finally these metal materials fall into the metal material collection area; the garbage on conveyor belt 1 without metal materials falls into the sorting area;

[0018] Wood chips, plastics and other impurities in the garbage that falls into the water in the sorting area float on the water surface. Under the action of servo motor 3, the conveyor chain 3 rotates. Under the scraping of the mesh plate, the floating impurities are pushed to the collection area and blocked by the debris retaining plate, preventing them from floating freely. Finally, the floating garbage is discharged from the debris removal port; while the garbage that sinks to the bottom of the sorting area is pushed to a position near the debris discharge port in the sorting area under the action of the mesh plate and scraper.

[0019] Step 3. In addition, under the action of the driving motor 1, the connecting plate drives the push-pull rod to move up and down, so that the top plate moves up and down. When the top plate moves upward, the dust in the crushing box 1 is sucked into the bellows through the air inlet. When the top plate moves downward, the gas containing dust in the bellows is discharged from the air outlet. The discharged airflow enters the dust collecting component through the exhaust pipe 1. Under the action of the cyclone separator, the dust accumulates in the dust collecting box. The airflow is filtered by the pull-type filter component and then discharged from the exhaust port and discharged to the cleaning component through the exhaust pipe 2; the airflow blows the fan blades to rotate the rotating tube, and then the airflow enters the rotating tube from the air inlet and is finally discharged from the air outlet. When the rotating tube rotates, the bristles clean the adsorption component and the conveyor plate chain 2;

[0020] Step 4: When the threshold measured by the liquid level sensor exceeds the maximum value among the liquid level thresholds, the controller starts the water pump, turns off the drive motor 1, servo motor 1, servo motor 2, and servo motor 3, and the water in the sorting area is transported to the water tank. When no more water is discharged from the sorting area, the water pump is turned off, the servo motor 3 and drive motor 2 are started, and the valve at the discharge port is opened. The garbage in the sorting area is discharged into the crushing box 2 for extrusion and crushing. The extruded and crushed garbage is finally discharged from the recycling port.

[0021] Step 5: After the garbage in the sorting area is discharged, turn off the water pump and drive motor 2, open the solenoid valve to inject water into the sorting area, and when the water level reaches the minimum value of the liquid level threshold, the controller closes the solenoid valve;

[0022] Step 6. Repeat steps 2-5.

[0023] The present invention has outstanding substantial features and significant progress compared to the prior art. Specifically, the present invention has the following advantages:

[0024] The construction waste classification and processing device provided by the present invention facilitates the crushing of construction waste and separates it into four categories: dust waste, floating waste, metal waste, and concrete sand and gravel waste for collection, thereby maximizing resource recycling under the premise of energy saving and environmental protection. At the same time, the equipment has the technical advantages of being easy to operate and use and having low construction cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The method for using the above-mentioned construction waste classification and processing device is characterized by comprising the following steps:

[0047] Step 1: First, the speeds of the drive motor 1, the drive motor 2, the servo motor 1, the servo motor 2, and the servo motor 3 are set through the controller 26, and the liquid level threshold measured by the liquid level sensor 25 is set;

[0048] Step 2: Start the drive motor 1, servo motor 1, servo motor 2, and servo motor 3, and put the construction waste to be crushed into the feeding bin 2-6. Under the action of the servo motor 1, the crushing roller 2-3 crushes the waste, and the crushed waste falls onto the conveyor belt 1. As the conveyor belt 1 rotates, the waste is pushed forward;

[0049] Driven by the servo motor 2, the conveyor plate chain 2 5-2 rotates, and after the transmission gear 5-5 in the adsorption component engages with the rack 1 8, the rotating rod 5-3 rotates, and the electromagnetic rod 5-4 stirs the material on the conveyor belt 1. In addition, after the contact switch on the transmission gear 5-5 is touched by the rack 1 8, the electromagnetic rod 5-4 is energized. After the contact switch is triggered, the electromagnetic rod 5-4 is energized, and the electromagnetic rod 5-4 adsorbs the metal substances in the slag. When the contact switch on the transmission gear 5-5 touches the rack 2 9, the electromagnetic rod 5-4 is de-energized, and the metal substances fall onto the conveyor plate chain 2 5-2, and finally these metal substances fall into the metal substance collection area; the garbage on the conveyor belt 1 without metal substances falls into the sorting area;

[0050] Wood chips, plastics and other impurities in the garbage that falls into the water in the sorting area float on the water surface. Under the action of the servo motor 3, the conveyor chain 3 10-1 rotates. Under the scraping of the mesh plate 10-3, the floating impurities are pushed to the collection area and blocked by the debris blocking plate 24, preventing them from floating freely. Finally, the floating garbage is discharged from the debris removal port 1-1; and the garbage that sinks to the bottom of the sorting area is pushed to the position of the sorting area near the debris discharge port 19-6 under the action of the mesh plate 10-3 and the scraper 10-2.

[0051] Step 3. In addition, under the action of the driving motor 1, the connecting plate 3-9 drives the push-pull rod 3-7 to move up and down, so that the top plate 3-1 moves up and down. When the top plate 3-1 moves upward, the dust in the crushing box 2-1 is sucked into the bellows 3-5 through the air inlet 3-3. When the top plate 3-1 moves downward, the gas containing dust in the bellows 3-5 is discharged from the air outlet 3-6. The discharged air flow enters the dust collecting assembly 19 through the exhaust pipe 20 and is discharged in the cyclone separator 19. -3, dust accumulates in the dust collecting box 19-1, and the air flow is filtered by the pull-out filter assembly 19-5 and then discharged from the exhaust port 19-4, and discharged to the cleaning assembly 22 through the exhaust pipe 21; the air flow blows the fan blades 22-4 to make the rotating pipe 22-2 rotate, and then the air flow enters the rotating pipe 22-2 from the air inlet 22-5 and is finally discharged from the air outlet 22-6. When the rotating pipe 22-2 rotates, the brush bristles 22-7 clean the adsorption assembly and the conveyor plate chain 2 5-2;

[0052] Step 4: When the threshold value measured by the liquid level sensor 25 exceeds the maximum value among the liquid level threshold values, the controller 26 starts the water pump 14, turns off the drive motor 1, servo motor 1, servo motor 2, and servo motor 3, and the water in the sorting area is transported to the water tank 16. When no more water is discharged from the sorting area, the water pump 14 is turned off, the servo motor 3 and the drive motor 2 are started, and the valve 23 at the discharge port 19-6 is opened. The garbage in the sorting area is discharged into the crushing box 2 27-1 for extrusion and crushing. The extruded and crushed garbage is finally discharged from the recycling port.

[0053] Step 5: After the garbage in the sorting area is discharged, the water pump 14 is turned off, the second drive motor is turned off, and the solenoid valve is opened to inject water into the sorting area. When the water level reaches the minimum value of the liquid level threshold, the controller 26 closes the solenoid valve;

[0054] Step 6. Repeat steps 2-5.

[0055] Finally, 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 the present invention. Although the present invention has been described in detail with reference to preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solutions of the present invention.

Under the action of the servo motor 1, the crushing roller (2-3) crushes the waste, and the crushed waste falls onto the conveyor belt 1. As the conveyor belt 1 rotates, the waste is pushed forward; Driven by the servo motor 2, the conveyor plate chain 2 (5-2) rotates, and after the transmission gear (5-5) in the adsorption component is engaged with the rack 1 (8), the rotating rod (5-3) rotates, and the electromagnetic rod (5-4) stirs the material on the conveyor belt 1. In addition, after the contact switch on the transmission gear (5-5) is touched by the rack 1 (8), the electromagnetic rod (5-4) is energized. After the contact switch is triggered, the electromagnetic rod (5-4) is energized, and the electromagnetic rod (5-4) adsorbs the metal substances in the slag. When the contact switch on the transmission gear (5-5) touches the rack 2 (9), the electromagnetic rod (5-4) is de-energized, and the metal substances fall on the conveyor plate chain 2 (5-2). Finally, these metal substances fall into the metal substance collection area; the garbage on the conveyor belt 1 without metal substances falls into the sorting area; Wood chips, plastics and other impurities in the garbage that falls into the water in the sorting area float on the water surface. Under the action of the servo motor three, the conveyor chain three (10-1) rotates. Under the scraping of the mesh plate (10-3), the floating impurities are pushed to the collection area and blocked by the debris blocking plate (24), preventing them from floating freely. Finally, the floating garbage is discharged from the debris removal port (1-1); and the garbage that sinks to the bottom of the sorting area is pushed to a position near the debris discharge port (19-6) in the sorting area under the action of the mesh plate (10-3) and the scraper (10-2). Step 3. In addition, under the action of the driving motor 1, the connecting plate (3-9) drives the push-pull rod (3-7) to move up and down, so that the top plate (3-1) moves up and down. When the top plate (3-1) moves upward, the dust in the crushing box 1 (2-1) is sucked into the bellows (3-5) through the air inlet (3-3). When the top plate (3-1) moves downward, the gas containing dust in the bellows (3-5) is discharged from the air outlet (3-6). The discharged air flow enters the dust collecting assembly (19) through the exhaust pipe 1 (20) and is discharged in the cyclone separator (19- 3), dust accumulates in the dust collecting box (19-1), and the air flow is filtered by the pull-out filter assembly (19-5) and then discharged from the exhaust port (19-4), and discharged to the cleaning assembly (22) through the exhaust pipe (21); the air flow blows the fan blades (22-4) to make the rotating tube (22-2) rotate, and then the air flow enters the rotating tube (22-2) from the air inlet (22-5) and is finally discharged from the air outlet (22-6). When the rotating tube (22-2) rotates, the brush bristles (22-7) clean the adsorption assembly and the conveyor plate chain (5-2); Step 4: When the threshold value measured by the liquid level sensor (25) exceeds the maximum value among the liquid level threshold values, the controller (26) starts the water pump (14), turns off the drive motor 1, the servo motor 1, the servo motor 2, and the servo motor 3, and the water in the sorting area is transported to the water tank (16). When no more water is discharged from the sorting area, the water pump (14) is turned off, the servo motor 3 and the drive motor 2 are started, and the valve (23) at the discharge port (19-6) is opened. The garbage in the sorting area is discharged into the crushing box 2 (27-1) for extrusion and crushing. The extruded and crushed garbage is finally discharged from the recycling port. Step 5: After the garbage in the sorting area is discharged, the water pump (14) is turned off, the second drive motor is turned on, and the solenoid valve is opened to inject water into the sorting area. When the water level reaches the lowest value of the liquid level threshold, the controller (26) closes the solenoid valve; Step 6. Repeat steps 2-5.
