Description

Technical Field

[0001] This utility model relates to the technical field of construction waste screening and sorting devices, and in particular to a construction waste screening and sorting device. Background Technology

[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and stones, and other waste generated during construction activities such as demolition, construction, decoration, and repair. Based on its source, construction waste can be divided into construction waste from construction sites and demolition waste from demolition. To better reuse construction waste, it is necessary to classify and recycle it. For example, Chinese utility model patent CN219836575U describes a construction waste sorting and recycling device, including a conveyor box. A sorting hood is fixedly connected to the upper surface of the conveyor box. A blower is fixedly installed on the right side of the sorting hood, with its outlet penetrating through the hood and extending into its interior. A bearing ring is fixedly embedded in the inner wall of the sorting hood, and a crushing shaft is fixedly connected to the inner ring of the bearing ring. A drive motor is fixedly installed on the back of the conveyor box, with its output end fixedly connected to the rear end of the crushing shaft. A mesh conveyor is installed on the inner wall of the conveyor box. A feed hole is provided on the upper surface of the conveyor box. Two guide plates are fixedly connected to the inner wall of the sorting hood, both located above the feed hole. A sorting hole is provided on the left side of the sorting hood. This device achieves continuous processing of construction waste and improves the recycling speed during construction waste treatment.

[0003] The above-mentioned device still has some problems in use. The device is used to transport and screen the particles of different sizes in construction waste before proceeding to the next operation. However, the device cannot screen construction waste of different materials. The reuse directions of different materials are also different. The construction waste screened by the device still needs to be sorted a second time, which affects the work efficiency. Utility Model Content

[0012] This utility model discloses a construction waste screening and sorting device. In use, construction waste is fed into the inlet and falls onto a conveyor belt. The motor is started, and the conveyor belt begins to rotate. Simultaneously, a fan is turned on to blow the construction waste on the conveyor belt, causing lightweight and small debris to fall into the discharge chute. Other construction waste falls into a water tank through the discharge plate. The water inlet valve is opened, and water flows into the water tank through the inlet pipe. The construction waste falls into the water tank; less dense materials such as plastic and wood float on the surface, while denser materials such as metal and stone fall onto the lower baffle at the bottom of the water tank. The floating construction waste is scooped out. The water outlet valve is opened, and water flows out of the water tank through the outlet pipe. The lower baffle is removed, and the construction waste that fell onto it falls into a collection box. The box door is opened, and the construction waste is removed, thus completing the waste screening and sorting process. This device can screen and sort construction waste of different volumes and densities without requiring secondary sorting, improving work efficiency. Attached Figure Description
