Description

Technical Field

[0001] This utility model relates to the field of recycled aggregates, and in particular to a device for removing impurities from recycled aggregates. Background Technology

[0002] The preparation of recycled aggregates from construction waste is currently a key focus of research on the recycling of construction waste. With the increasing awareness of sustainable development and the development of science and technology, more and more solid waste can be recycled, most of which becomes recycled aggregates. Current construction waste contains some organic matter, including paper scraps, plastic fragments and other organic impurities. After primary crushing, these impurities are mixed in with the recycled aggregates, affecting the quality of the recycled aggregates and hindering their production. Therefore, specialized impurity removal devices are used to remove impurities from this part of the waste.

[0003] Currently, most common equipment on the market for removing lightweight waste from recycled aggregates uses roller screens to screen construction waste, and then blows the lightweight waste on the rollers into an exhaust duct on the other side using a blower. In this type of equipment, various types of lightweight waste discharged through the exhaust duct usually scatter or drift to various places on the side of the device, making it difficult to collect effectively. Afterwards, workers need to manually clean up the area around the equipment, which is very time-consuming and labor-intensive. In addition, a lot of dust is blown out of the exhaust duct, and this dust is raised into the air outside the frame, which can easily harm the health of nearby workers.

[0004] Therefore, it is necessary to provide a new device for removing impurities from recycled aggregates to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a recycled aggregate cleaning device that can effectively collect and sort lightweight waste discharged from the air outlet duct, while effectively suppressing dust generated at the air outlet duct.

[0006] To solve the above-mentioned technical problems, the present invention provides a recycled aggregate impurity removal device comprising: a frame, a conveying assembly, an air separation assembly, and a collection assembly. The front and rear side walls of the frame are respectively provided with air outlets and air inlets. The air outlets and air inlets, which are distributed front to back, are arranged in several groups on the surface of the frame in a stepped manner. The number of conveying assemblies corresponds to the number of air inlets and are all arranged on the surface of the frame below the air inlets. The air separation assembly is installed on the top of the frame.

[0007] Air outlet pipes are fixedly connected to the outer surface of the frame of several air outlets. A top plate is fixedly connected between the bottoms of several air outlet pipes. A box is fixedly connected to the bottom of the top plate. A bracket is fixedly connected to the bottom of the box. A second rotating roller is rotatably connected to both ends of the bracket. A second belt is connected between two second rotating rollers. A second motor is fixedly connected to one side wall of the bracket. The output end of the second motor is fixedly connected to the end of one side of the second rotating roller. A connecting pipe is provided on the outer side of the top plate. Several atomizing nozzles are installed on the surface of the connecting pipe.

[0008] As a further embodiment of this utility model, the surface of the box is provided with several openings, and baffles are fixedly connected to the front and rear edges of the top of the support on one side of the box.

[0009] Through the above technical solution, the device has a box set on one side of the air outlet pipe. The airflow of the fan enters the frame through the air inlet and blows the construction waste on the roller on one side, causing some of the lightweight waste to be discharged through the air outlet pipe. In order to prevent the waste in the air outlet pipe from falling randomly to the ground, the end of the air outlet pipe is connected to the box, thereby intercepting various lightweight wastes. At the same time, a second belt is added to the bottom of the box to automatically transport various wastes to the designated location, so that workers do not need to manually clean and sweep. This structural design can save labor costs and reduce the workload of workers.

[0010] As a further embodiment of this utility model, the conveying assembly includes a plurality of uniformly arranged rollers, the rollers being rotatably connected to the inner wall of the frame, and the ends of the plurality of rollers passing through the surface of the frame and fixedly connected to sprockets, the plurality of sprockets being connected to each other by chains, and a drive motor being fixedly connected to one side wall surface of the frame, the output end of the drive motor being fixedly connected to the end of one side roller.

[0011] Through the above technical solution, several sets of rollers in the device are distributed in a stepped manner. Each set of rollers is driven by chains and sprockets, and utilizes the power of the drive motor to rotate.

[0012] As a further embodiment of this utility model, a first rotating roller is rotatably connected to the frame surface located below the plurality of rollers. Two first rotating rollers are provided inside the frame, and a first belt is connected between the two first rotating rollers. A first motor is fixedly connected to one side wall surface of the frame, and the output end of the first motor is fixedly connected to the end of one side of the first rotating roller.

[0013] With the above technical solution, there is a certain gap between the rollers, allowing various smaller impurities in the construction waste to pass through the gap and fall onto the first conveyor belt for separate collection.

[0014] As a further embodiment of this utility model, the number of air separation components matches the number of air inlets. Each air separation component includes a fan, which is fixedly connected to the top of the frame. A flexible hose is fixedly connected to the output end of the fan, and a cover is fixedly connected to the end of the flexible hose. The cover is fixedly connected to an air inlet on the adjacent side.

[0015] Through the above technical solution, the device uses the combination of air, hose and air inlet to blow air into the frame to blow the light waste on one side roller into the air outlet.

[0016] As a further embodiment of this utility model, the several sets of rollers are arranged in a stepped manner, with a feed plate fixedly connected to the frame surface on one side of the roller at the top, and a discharge plate fixedly connected to the frame surface on one side of the roller at the bottom.

[0017] The above technical solution allows construction waste to be fed into the first roller step inside the frame via the feed plate. After being screened by multiple sets of conveying components and air separation components, the construction waste is discharged through the discharge plate.

[0018] As a further embodiment of this utility model, the connecting pipe is connected to a water pump via a pipeline, the water pump is fixedly connected to the top of the top plate, and the input end of the water pump is connected to an external water source via a pipeline.

[0019] Through the above technical solution, the device has an opening on the surface of the housing to facilitate observation by external personnel and to allow for timely handling of blockages and other problems. In order to prevent the airflow from the exhaust pipe from stirring up a large amount of dust, the structure is equipped with connecting pipes and atomizing nozzles around the outer edge of the top plate, thereby effectively reducing the dust content in the air around the equipment.
