Problems solved by technology

Inertial separation resistance is originally the smallest, but due to the large body, large steel consumption, large space occupation, and long pipeline, the resistance is slightly lower than that of cyclone separation
[0008] 2) Sorting efficiency is low

Embodiment 1

[0053] see figure 1 , 2, 3. This embodiment is a single-drum wind separation device designed according to the technical solution of the present invention. It includes a feed conveyor 1, a fan 2, an air distribution device 3, a winnowing room 4, a relay drum 5, a centrifugal sedimentation separator 6, a light material output conveyor 7, a heavy Material output belt conveyor 8, a group of return air duct 9, a set of bag filter. Centrifugal sedimentation separator 6 adopts electric push rod valve 16, and ring grate 17 and grid grate 18 are arranged on the top cover. These components are integrated on the same frame together with the maintenance platform. The scraper of the feeding conveyor 1 is placed near the tail roller, and connects the hopper and the slag truck under it. Below the centrifugal sedimentation separator 6, a slag car is also connected by bellows. A soft plastic strip is used at the position where the 4 blanking openings of the winnowing chamber are connected...

Embodiment 2

[0060] see Figure 4 , 5 , the present embodiment is a double-drum wind separation device designed according to the technical solution of the present invention. The difference from Embodiment 1 is that the winnowing chamber 4 is extended, and a secondary relay drum 10 and secondary heavy material output conveyor 11 are additionally arranged. The air distribution device 3 has increased a branch air pipe, and stretches into the winnowing room 4 between the two conveyors.

Abstract

The invention relates to an air sorting device, which belongs to the field of air sorting technology for chemical material. The system comprises an air blower (2), an air register (3), an air sorting chamber (4), a relay drum (5), a settling centrifuge (6), an input material conveyor (1), a heavy material output conveyor (8), a light material output conveyor (7), an air return pipe (9), a stand, a dust remover and a control system. The settling centrifuge (6) includes a transmission device (12), a pin wheel (13), a ring grate (17) and a bar grate (18). The system adopts the relay drum (5) to reduce the air active section to compensate for the short migration distance of light material under the action of air force, thus obviating the secondary falling back and mixing of the sorted light material. Additionally, an intensely centrifugal air flow is used for separating particles and dust, and high-speed rotation energy can be converted into dynamic pressure by discharging air through a volute. The system has the advantages of compact structure, less occupied area, short pipe, less resistance, strong air power of the air sorting chamber, high sorting efficiency and stable and reliableoperation. The air sorting unit device can be used for sorting oversize plastics of urban life garbage and for sorting other industrial mixed materials.

Description

1. Technical field [0001] The invention belongs to the technical field of wind power separation of chemical materials, and relates to the plastic separation technology of municipal domestic waste. 2. Background technology [0002] Municipal solid waste contains a large amount of plastic. The pre-sorting of comprehensive waste treatment projects is aimed at resource recovery and recycling. [0003] Plastic sorting generally adopts wind sorting technology. At present, the main difference of various wind separation technologies is reflected in the separation and collection methods of plastics, including inertial sedimentation separation, drum filtration separation, and cyclone separation. [0004] These devices currently face the following unresolved problems: [0005] 1) The system resistance is large and the energy consumption is relatively high [0006] It is difficult to integrate the drum filter with the sorting chamber, and a section of pipeline is usually connected. ...
