[0016] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an online chain-plate type light material negative pressure air separator includes a chain-plate conveyor, which is positioned above the belt 9 of the main conveyor belt. The running direction of the chain plates is perpendicular to the running direction of the belt. The chain-plate conveyor is a chain-plate type light material negative pressure air separator. The chain-plate type light material negative pressure air separator includes a frame, with a driven wheel 1 at one end and a tension wheel 2 and a drive wheel 3 at the other end. A chain is fitted onto the drive wheel, tension wheel, and driven wheel. Several chain plates are installed on the chain, with chain plate gap holes between adjacent chain plates. The chain and chain plates constitute the chain plate of this utility model. A negative pressure chamber 5 with an open lower part is provided on the frame between the upper and lower parts of the chain plate. The open part of the negative pressure chamber corresponds to the lower part of the chain plate. A negative pressure dust collection pipe 7 is provided on one side of the negative pressure chamber 5, and a compressor is installed on the negative pressure dust collection pipe. A light material collection device 8 is provided at the tail of the chain plate.

[0017] like Figure 4 As shown, in order to reduce equipment layout and lower investment costs, this low-cost chain plate type light material negative pressure air classifier utilizes the main conveyor belt 9 on the production line to install the chain plate type light material negative pressure air classifier. That is, on the fixed support of the main conveyor belt (in Figure 4 The chain plate type light material negative pressure air separator is directly installed on the main conveyor belt (the fixed support is omitted). The chain plate type light material negative pressure air separator is installed at a certain position on it along the movement direction of the main conveyor belt. The running direction of the main conveyor belt is perpendicular to the running direction of the chain plate of the chain plate type light material negative pressure air separator. The specific height is so as not to affect the material conveying. At the same time, the moving chain plate under the negative pressure chamber of the chain plate type light material negative pressure air separator can adsorb light materials in the material as much as possible. This arrangement height can be freely adjusted.

[0018] The negative pressure chamber 5 of this utility model is the main structure of the online chain plate type light material negative pressure air classifier. It is connected to the compressor through flanges, pipes, etc., so that a negative pressure environment is generated in the chamber. Light materials in the material on the belt are adsorbed on the lower part of the chain plate and carried to the non-negative pressure area at the tail of the air classifier, and then fall into the light material collection device 8.

[0019] The chain plate 6 is the main moving mechanism of the online chain plate type light material negative pressure air separator. Under the support of the driven roller 1 and tension roller 2, and driven by the power of the drive wheel 3, the chain plate 6 rotates counterclockwise. Relying on the negative pressure in the negative pressure cavity at its upper part, the light materials in the material on the main belt are adsorbed at its lower part. By moving the chain plate, the light materials are carried to the light material online collection device 8.

[0020] In this invention, the drive wheel 3 is driven to rotate by a variable frequency motor through a reducer. The chain rotates along with the drive wheel, tension wheel, and driven wheel to achieve the purpose of operation.

[0021] This invention utilizes the suction force generated by negative air pressure. During operation, a negative pressure environment is created within the air separator's negative pressure chamber. Dust and other particles in the material are carried to the dust collection system through the ventilated gaps in the chain plates. Lighter materials such as plastic bags, plastic sheets, cardboard boxes, old clothes and fabrics, sponges, foam, asbestos cloth, and asbestos boards are adsorbed under the counterclockwise rotating chain plates by the negative pressure airflow. After being carried to the tail end of the chain plate, these lighter materials leave the negative pressure area, the suction is removed, and they automatically fall into the light material collection device 8.

[0022] The online chain-plate type negative pressure air separator for lightweight materials described in this utility model has an elastic brush cleaning device 4 installed on the side of the chain. This elastic brush cleaning device is positioned above the lightweight material collection device.

[0023] The online chain plate type negative pressure air separator for light materials of this utility model includes an elastic brush cleaning device comprising an elastic brush roller 43 and a brush adjustment support frame 41. The bristles of the elastic brush extend into the gap holes of the chain plate. Brush mounting frames 41 are respectively provided at both ends of the roller shaft of the elastic brush roller. The brush adjustment support frame is mounted on the machine frame and has a strip hole 42. Bolts pass through the roller shaft end of the elastic brush roller and the strip hole to fix the screw end of the elastic brush to the brush adjustment support frame.

[0024] This utility model features an elastic brush that adheres closely to the outer side of the chain plates, serving as a cleaning device for removing dirt adhering to the chain plates and fine materials clogging the gaps and holes. It utilizes the elasticity of nylon bristles to penetrate deep into the gaps and holes of the chain plates, clearing away the fine materials clogging them. As the wear-resistant nylon bristles wear down, bolts are used to adjust their position in the slotted holes, allowing the nylon bristle cleaner to continue functioning until it fails and needs to be replaced.

[0025] The online chain plate type light material negative pressure air separator of this utility model has two driven wheels respectively located above and below one side of the frame, and a tension wheel and a drive wheel respectively located above and below the other side of the frame. The tension wheel is adjustable, and the wheel axle of the tension wheel is mounted on the tension wheel mounting bracket through an adjusting screw.
