[0002] Construction waste refers to solid waste generated during construction activities, including the construction, renovation, expansion, and demolition of buildings, structures, and municipal infrastructure. The proper handling of construction waste is of great significance for environmental protection, as it can reduce resource waste, lower the risk of environmental pollution, and promote the development of a circular economy.

[0003] Construction waste contains various materials, so when recycling construction waste, it is necessary to screen the materials. When recycling plastics from construction waste, the first step is to screen them out. Current methods for screening plastics from construction waste generally include manual sorting, air separation, and flotation. Manual sorting requires a lot of manpower and is slow. Air separation cannot screen some heavier plastics, affecting the screening effect. Although flotation can effectively separate plastics from other construction waste, it still requires manual collection of plastics floating on the water surface. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] This application provides a construction waste plastic recycling and processing device. The device uses a pushing component to push out and collect the plastic that floats on the water surface after screening, thereby accelerating the screening efficiency of plastic. The adjusting component can pour the screened construction waste out of the screening box and then pour the construction waste to be screened back into the screening box for screening. This cycle is repeated to achieve the effect of screening plastic from construction waste.

[0022] The following provides a detailed description of the construction waste plastic recycling and processing device. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example

[0024] Please see Figures 1-7In this embodiment, a construction waste plastic recycling and processing device is provided, including: a water storage tank 1, a screening box 101 is provided inside the water storage tank 1, and a pushing component is provided on the top of the screening box 101 for pushing out the plastic floating on the top of the screening box 101. The pushing component includes: a push plate 102 is provided inside the water storage tank 1, a motor 103 is provided on one side of the top of the water storage tank 1, a lead screw 104 is driven and connected to one side of the outer end of the motor 103, a driving plate 105 is connected to one side of the top of the push plate 102, and a lead screw hole 106 is provided on one side of the outer end of the driving plate 105 for threaded engagement with the lead screw 104.

[0025] The water storage tank 1 has a bottom plate 2 installed at the bottom and a top plate 201 installed at the top. Support plates 202 are fixedly connected to both sides of the bottom of the top plate 201. The bottom of the support plates 202 is connected to the bottom plate 2. Fixing plates 203 are connected to both sides of the bottom of the top plate 201. The motor 103 is bolted to one side of the outer end of one of the fixing plates 203. One end of the lead screw 104 is rotatably connected to the other fixing plate 203 through a bearing. When the screening box 101 sinks into the water storage tank 1, the plastic inside the screening box 101 will float to the water surface due to the strong buoyancy of the plastic. At this time, the motor 103 drives the lead screw 104 to rotate, which drives the plate 105 to move the push plate 102 left and right through the lead screw hole 106 as the lead screw 104 rotates. Therefore, the floating plastic on the water surface can be pushed to the discharge port 701 by the push plate 102.

[0026] The screening box 101 is equipped with adjustment components on both sides of its outer end for adjusting its height. The adjustment components include: two electric telescopic rods 3 connected to the top of the bottom plate 2; vertical plates 301 connected to both sides of the top of the screening box 101; and horizontal plates 302 connected to one side of the outer end of each of the two vertical plates 301. When the screening box 101 is in use, the electric telescopic rods 3 drive the slider 4 to rise and fall. Since the slider 4 is engaged inside the slide groove 401, the slider 4 can drive the screening box 101 to rise and fall through the horizontal plates 302 and the vertical plates 301 when it rises and falls, thereby lowering the bottom of the screening box 101 into the water storage tank 1. Then, the construction waste to be screened is poured into the screening box 101, and then the screening box 101 is completely submerged in the water inside the water storage tank 1.

[0027] The top of the electric telescopic rod 3 is rotatably connected to the slider 4 via a rotating shaft. Both sides of the bottom of the two horizontal plates 302 are provided with sliding grooves 401. The slider 4 is slidably connected to the sliding grooves 401. Since the slider 4 can slide inside the sliding grooves 401 and the slider 4 is rotatably connected to the electric telescopic rod 3 via a rotating shaft, it can be ensured that the electric telescopic rods 3 on the left and right sides can raise the left and right sides of the screening box 101 to different height positions respectively.

[0028] The screening box 101 has a discharge port 5 on one side of its outer end, and a ramp 501 is connected to one side of the outer end of the water storage tank 1. A receiving box 502 is provided on one side of the top of the bottom plate 2. After the push plate 102 cleans the plastic on the water surface, the screening box 101 is raised by the electric telescopic rod 3 until the discharge port 5 slides completely out of the water storage tank 1. Then, the two electric telescopic rods 3 on the left side stop raising the screening box 101, while the two electric telescopic rods 3 on the right side continue to raise the right side of the screening box 101. The screen box 101 is raised to a leftward tilt position. At this time, the construction waste inside the screen box 101 will be discharged from the discharge port 5 to the top of the inclined plate 501, and the construction waste will be guided into the receiving box 502 through the inclined plate 501. Then, the construction waste to be screened can be poured into the screen box 101 for screening. When the screen box 101 is raised, the push plate 102 and the drive plate 105 are located on the far right inside the water storage tank 1, and will not affect the raising and lowering of the screen box 101.

[0029] The base plate 2 has a water collection tank 6 on one side of its top. The water collection tank 6 has a collection frame 601 on its top. The bottom of the collection frame 601 has multiple drainage holes 602. The bottom sides of the water collection tank 6 are connected to positioning blocks 603. The top sides of the water collection tank 6 have positioning grooves 604 that are slidably connected to the positioning blocks 603. When plastic falls into the collection frame 601, the water mixed in with the plastic can be drained into the water collection tank 6 through the drainage holes 602. When it is necessary to collect the plastic inside the collection frame 601, the collection frame 601 is moved away from the water storage tank 1 until the collection frame 601 slides completely out from the bottom of the guide plate 704. Then the collection frame 601 can be lifted and separated from the water collection tank 6. The positioning blocks 603 and positioning grooves 604 are used to position the collection frame 601 and the water collection tank 6, so that the collection frame 601 can be installed on the top of the water collection tank 6.

[0030] Two electric push rods 7 are installed on both sides of the outer end of the water storage tank 1. A discharge port 701 is opened on one side of the top of the water storage tank 1. A blocking plate 702 is installed inside the discharge port 701. A lifting plate 703 is connected to the top of the blocking plate 702. The tops of the two electric push rods 7 are connected to the lifting plate 703. A guide plate 704 is connected to one side of the outer end of the water storage tank 1. When the push plate 102 pushes the floating plastic, the electric push rods 7 push the lifting plate 703 and the blocking plate 702 upward, so that the floating plastic can pass through the discharge port 701 and be transported to the guide plate 704. The guide plate 704 guides the plastic into the collection frame 601. After the construction waste in the screening box 101 is replaced, the blocking plate 702 needs to be lowered into the discharge port 701 to block it. Water needs to be added to the water storage tank 1 through an external water pipe to ensure that there is enough water in the water storage tank 1 to float the plastic to the height of the discharge port 701.

[0031] Working principle:

[0032] When using this device, the slider 4 is raised and lowered by the electric telescopic rod 3. Since the slider 4 is engaged inside the chute 401, the raising and lowering of the slider 4 can drive the screening box 101 to rise and fall through the horizontal plate 302 and the vertical plate 301, thereby lowering the bottom of the screening box 101 into the water storage tank 1. Then, the construction waste to be screened is poured into the screening box 101, and then the screening box 101 is completely submerged in the water inside the water storage tank 1. Since plastic has strong buoyancy, the plastic inside the screening box 101 will float to the surface of the water. At this time, the motor 103 drives the lead screw 104 to rotate, and the drive plate 105 drives the push plate 102 to move left and right through the lead screw hole 106 as the lead screw 104 rotates. Therefore, the push plate 102 can push the floating plastic on the water surface towards the discharge. At point 701, the lifting plate 703 and the blocking plate 702 are pushed upward by the electric push rod 7, so that the floating plastic can pass through the discharge port 701 and be transported to the guide plate 704. The guide plate 704 guides the plastic into the collection frame 601. After the plastic falls into the collection frame 601, the water mixed in with the plastic can be drained into the water collection tank 6 through the drain hole 602. When it is necessary to collect the plastic inside the collection frame 601, the collection frame 601 is moved away from the water storage tank 1 until the collection frame 601 slides completely out from the bottom of the guide plate 704. Then the collection frame 601 can be lifted and separated from the water collection tank 6. The positioning block 603 and the positioning groove 604 are used to position the collection frame 601 and the water collection tank 6, so that the collection frame 601 can be installed on the top of the water collection tank 6.
