However, the composition of garbage is extremely complex, among which light materials such as plastics, paper, lunch boxes, and wood chips account for a large proportion, especially plastics. The particularity of plastic chemical properties determines that its follow-up treatment is completely different from other materials. If plastic materials can be sorted and recycled in advance, on the one hand, the amount of garbage can be greatly reduced, on the other hand, it is convenient for centralized recycling and treatment, and the efficiency of recycling can be improved. , so how to efficiently and accurately sort recycled plastics has very realistic social and economic significance.

Detailed ways

In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

Please refer to Fig. 1 and Fig. 2, a kind of waste processing positive pressure sorting machine of the present invention, comprises fan 1, and fan 1 is communicated with receiving chamber 4 through air duct 2, and the upper end of receiving chamber 4 is feed inlet 3, and the lower end It is the outlet 10 of the remaining material after sorting, one side communicates with the air supply duct 2, and the other side communicates with the settling chamber 5, and the air supply duct 2 is arranged obliquely upward on the upper part of the material receiving chamber 4 and below the feed port, and the settling chamber 5 The cross section of the settling chamber is much larger than the cross section of the material receiving chamber 3. The top of the settling chamber 5 is provided with a suction duct 7, and the middle part is provided with a disc screen 6, and a material receiving conveyor is installed under the discharge port 11 of the disc sieve. 9. A plastic conveyor 8 is installed below the discharge port of the disc sieve.

The above-mentioned structure adopts a structure in which the section of the settling chamber is much larger than that of the receiving chamber. The large space of the settling chamber and the suction duct connected to the settling chamber greatly reduce the wind speed and pressure. The material settles on the disc sieve in the settling chamber by its own weight and inertial force, and the light particles with smaller particle size are further screened through the disc sieve, and the light particles fall on the receiving conveyor to be transported; The disc screen is transported to the plastic conveyor, which further removes the small light particles mixed in the plastic, greatly reduces the impurity content in the plastic, and solves the technical problems of incomplete plastic sorting and low sorting efficiency in the current domestic waste treatment project .

In order to further enhance the function of the present invention, in this embodiment,

The settling chamber is provided with a baffle 13 extending downward from the top. It can further reduce the wind pressure and wind speed, change the direction of the material, make it quickly settle on the disc screen, and improve the screening efficiency.

The above-mentioned receiving chamber is adjacently connected with the settling chamber. It can make the structure of the machine more compact and the layout more reasonable.

The above-mentioned feed inlet is vertically arranged on the top of the receiving chamber. Can make the layout of the machine more reasonable.

The above-mentioned suction duct is communicated with the blower fan. It can make the structure of the machine more compact and occupy less space.

The above-mentioned fan adopts a fan with adjustable air supply volume. The air supply volume can be adjusted according to the type of material to be processed, which can expand the scope of use of the machine.

The above-mentioned unsorted material outlet is connected with the receiving conveyor. One conveyor belt transports two kinds of materials, which saves equipment cost and has a reasonable and compact structure.

Above-mentioned suction pipe is provided with ventilation valve 12. It is used to adjust the air pressure of the whole machine. According to the actual situation of the garbage being processed, the air flow and air pressure are adjusted to make the operation of the equipment safer and more reliable.

Working principle of the present invention:

The adjustable fan acts on the material through the ventilation pipe and the ventilation valve so that the material enters the settling chamber with the function of settling and screening to realize the separation of plastics.

First, the material is fed from the feed port and falls into the receiving chamber, and the fan disperses the material in the receiving chamber through the air supply pipe. At this time, the air supply volume of the fan can be adjusted at any time according to the actual working conditions, and the plastic and light particles are blown with the airflow. Entering the settling chamber, the cross-sectional space of the settling chamber is much larger than that of the material receiving chamber. The larger space and the suction pipe connected to the fan suction port greatly reduce the wind speed and wind pressure. This structure changes the direction of air flow and material movement, so that the material settles on the disc screen in the settling chamber by its own weight and inertial force, and the light particles with smaller particle size are further screened through the disc screen, and the light particles fall on the receiving conveyor for delivery. ; The plastic that has not been screened out is transported to the plastic conveyor by the disc screen. The materials in the receiving chamber that are not sent into the settling chamber by the airflow are discharged from the unsorted material outlet and fall onto the conveyor. The whole process realizes the effective sorting of plastics and realizes the recycling of waste.
