Description

A device that uses system negative pressure to absorb and reduce external dust

technical field

The utility model relates to the technical field of aluminum powder, in particular to a device for absorbing and reducing external dust by means of system negative pressure.

Background technique

The dust generated in the production process of factories and mines, especially the dust generated in the processing of some organic matter, if the dust concentration is too high, explosion and combustion accidents will easily occur, and the dust concentration will also cause certain harm to the health of on-site workers.

Contents of the invention

In order to solve the above technical problems, the utility model provides a device that absorbs and reduces external dust by means of system negative pressure, which uses system negative pressure to absorb external dust for sieving, and after passing through the screen, the dust enters the dust collector for re-screening Separate collection, reduce the dust concentration inside the factory operation workshop, and collect suspended residual dust for reuse.

In order to achieve the above object, the utility model adopts the following technical solutions to realize:

A device that uses system negative pressure to absorb and reduce external dust, including a feeding device, a detachable silo, a negative pressure conveying device, a dust collector, and an air pressure balancing device. The feeding device is sequentially provided with a feeding port, a hopper, a material delivery valve, and a delivery pipeline from top to bottom. The detachable silo is connected to the conveying pipeline, and a screen is provided at the connection. The detachable silo is detachable, and screens of different meshes can be replaced. Both the detachable silo and the bottom of the dust collector are equipped with There is a discharge valve.

The detachable silo is sequentially connected with the negative pressure conveying device, the dust remover, the air pressure balance device, and the conveying pipeline through pipelines; the inside of the above-mentioned devices is vacuum, and the vacuum negative pressure cycle is used.

Compared with the prior art, the beneficial effects of the utility model are:

1) Vacuum treatment inside the system to reduce the possibility of explosion;

2) The negative pressure vacuum system is used to collect dust. After passing through the screen, the dust enters the dust collector for re-screening and collection to reduce the dust concentration inside the factory operation workshop;

3) The silo is detachable for easy recycling;

4) Collecting suspended residual dust not only saves energy and protects the environment, but also has certain economic and social benefits.

detailed description

The specific embodiment of the utility model will be further described below in conjunction with accompanying drawing:

As shown in Figure 1, a device that uses system negative pressure to absorb and reduce external dust includes a feeding device 1, a detachable silo 2, a negative pressure conveying device 3, a dust collector 4, and an air pressure balancing device 5. The feeding device is sequentially provided with a feeding port 6, a hopper 8, a material delivery valve 7, and a delivery pipeline 9 from top to bottom. The detachable silo 2 is connected with a conveying pipeline 9, and a screen 10 is provided at the connection. The detachable silo 2 is detachable and can be replaced with screens 10 of different meshes. Both the detachable silo 2 and the bottom of the dust collector 4 are provided with discharge valves 11 .

The detachable silo 2 is sequentially connected with the negative pressure conveying device 3, the dust collector 4, the air pressure balance device 5, and the conveying pipeline 9 through the pipeline 12; the inside of the above-mentioned devices is vacuum, and the vacuum negative pressure is used for circulation.

Example:

The negative pressure of the system is used to absorb external aluminum dust for screening, the negative pressure conveying device 3 provides the internal power of the system, and the air pressure balance device 5 ensures the stability of the internal power of the system. After the negative pressure conveying device 3 is started, the aluminum dust near the feed port 6 is filtered through the silo screen 10 and classified once. The material delivery valve 7 near the feed port 6 can be adjusted to adjust the feed amount. The classified aluminum dust whose particle size is smaller than the mesh size of the screen 10 enters the bag filter 4 for further collection.

The above embodiments are implemented on the premise of the technical solution of the present utility model, and detailed implementation methods and specific operation processes are given, but the protection scope of the present utility model is not limited to the above-mentioned embodiments. The methods used in the above examples are conventional methods unless otherwise specified.
