Problems solved by technology

[0006] But the above-mentioned patents all have the following problems: one is that the light garbage is only subjected to the wind force when it is at the end of the conveyor belt. At the end of the conveyor belt, the light garbage may also move downward due to inertia. In addition, the heavy garbage also begins to fall at the end of the conveyor belt. , heavy waste has a horizontal blocking effect on light waste, so that the wind cannot fully act on light waste, causing some light waste to e

Example Embodiment

[0069] Example 1

[0070] like Figure 1 to Figure 11 shown, is a preferred embodiment of the present invention.

[0071] The waste air separation system includes an air separation chamber 1, a conveyor belt 2, a fan 3, an air outlet duct 4, a first return air duct 5, a second return air duct 6, a heavy waste hopper 7, a light waste hopper 8, and a screen. 100, the diverting device 9, the toggle device 200, the feeding channel 300, the deceleration motor (not shown in the figure) and the like.

[0072] Wherein, the feed channel 300 communicates with the feed port 11 .

[0073] The selection chamber 1 has a hollow inner cavity, a feed inlet 11 communicating with the hollow inner cavity, a light waste outlet 12, a heavy waste outlet 13, a first air inlet 14, a second air inlet 15, and a first air return outlet 16. and the second air return port 17, the feed port 11 is located on the side wall of the air selection chamber 1 and a guide channel 1e is provided at the feed port 1...

Example Embodiment

[0100] Example 2

[0101] see Figure 12 to Figure 13 , the structure is basically the same as that of Embodiment 1, the difference is that: the cross section of the winnowing chamber 1 is a hollow Z-shaped.

[0102] The working principle and use method are the same as those in Example 1.

Abstract

The invention relates to a garbage air separation system. The system involves an air separation chamber, a conveying belt, a draught fan, an air outlet pipeline and a first air return pipeline; the air separation chamber is provided with a hollow inner cavity, a feeding port, a light garbage outlet, a heavy garbage outlet, a first air inlet and a first air return port; the air outlet pipeline extends into the hollow inner cavity of the air separation chamber, and the air outlet position of the air outlet pipeline is lower than and close to the conveying tail end of the conveying belt; the airseparation chamber is further provided with a second air return port and a second air inlet which communicate with the hollow inner cavity; and the air separation system further involves a second airreturn pipeline, the second air inlet is higher than the conveying belt and close to the conveying starting end of the conveying belt, and the second air return pipeline communicates with the air separation chamber to form an air duct of another cycle. According to the system, when mixed materials fall into the conveying belt, air begins to act on the mixed materials, light garbage on the conveying belt can be blown up instead of being blown up at the conveying tail end of the conveying belt, and therefore the light garbage are not prone to being transversely blocked by heavy garbage and is not prone to entering the heavy garbage outlet.

Description

technical field [0001] The invention relates to the technical field of garbage separation, in particular to a garbage winnowing system. Background technique [0002] Garbage can be divided into domestic waste, construction waste, etc. according to the field of source. The composition of garbage is complex, and it is mixed with many kinds of substances. In order to improve the resource utilization rate of garbage, it is necessary to classify the garbage for recycling and reuse. Sorting garbage by winnowing system is a common method in garbage separation. The air separation system is suitable for situations where there is a certain density difference between light garbage and heavy garbage and there is no adhesion. It can separate garbage (that is, mixed materials) into light garbage and heavy garbage. Light garbage can be plastic film, Foam, wood, etc. Heavy waste can be soil, gravel, slag, bones, leftovers, glass, etc. [0003] For example, household garbage is often wra...
