Abstract
The utility model relates to a technical field is carried to the powder, specifically is a negative pressure conveying system, and its safe material loading that can realize the powder can not lead to the fact the influence to workshop environment, and it includes powder jar, its characterized in that, be provided with negative pressure suction mouth and powder import on the powder jar, negative pressure suction mouth department installs primary filter, primary filter passes through negative pressure pipe connection negative-pressure air fan, install secondary filter on the negative pressure pipe.
Description
Technical Field
The utility model relates to a technical field is carried to the powder, specifically is a negative pressure conveying system.
Background
In the chemical industry, the powder is essential raw and other materials, and powder material loading in-process, common manual feeding operation causes the dust to fly upward very easily, causes environmental pollution to the workshop environment, and the dust meets open fire and still can explode moreover, causes serious influence to production.
Disclosure of Invention
Cause the workshop dust to fly upward easily when solving current dust material loading, have the problem of potential safety hazard, the utility model provides a negative pressure conveying system, its safe material loading that can realize the powder can not lead to the fact the influence to the workshop environment.
The technical scheme is as follows: the utility model provides a negative pressure conveying system, its includes the powder jar, its characterized in that, be provided with negative pressure suction mouth and powder import on the powder jar, negative pressure suction mouth department installs primary filter, primary filter passes through negative pressure pipeline and connects negative-pressure air fan, install secondary filter on the negative pressure pipeline.
The powder material tank is further characterized in that the powder material tanks comprise two groups, the negative pressure fan and the negative pressure pipeline are correspondingly arranged in two groups, one group comprises a single powder material tank, the other group comprises two powder material tanks which are arranged side by side, and the negative pressure pipeline is connected with the two powder material tanks which are arranged side by side through branch pipelines;
pressure sensors are arranged in the negative pressure pipeline and the powder tank;
and an emptying valve is arranged on the negative pressure pipeline.
Adopt the utility model discloses afterwards, during the material loading, close the powder import and open negative pressure suction mouth, form certain negative pressure with powder jar by negative pressure fan, then open the powder import, can let the material suck the powder jar smoothly under the negative pressure effect in, because two stage filter's existence, can prevent effectively that the dust from being sucked powder jar, negative pressure fan can not be to workshop discharge dust, guarantees workshop environment, has improved the security.
Drawings
Fig. 1 is a schematic view of the present invention.
Detailed Description
See fig. 1 and show, a negative pressure conveying system, it includes powder jar 1, be provided with negative pressure suction mouth and powder import on the powder jar 1, negative pressure suction mouth department installs primary filter 2, primary filter 2 passes through negative pressure pipeline 3 and connects negative-pressure air fan 4, negative-pressure air fan 4 generally adopts roots's fan, install secondary filter 5 on the negative pressure pipeline 3, primary filter 2 blocks most dust in powder jar 1, the powder that the trace was leaked is blockked by secondary filter 5 when negative pressure pipeline 3, thereby double filtration has been realized, the reliability of blocking the dust is greatly improved.
Generally, a plurality of devices are arranged in a workshop, so that in the embodiment, the powder tanks 1 comprise two groups, the negative pressure fan 4 and the negative pressure pipeline 3 are correspondingly arranged into two groups, one group is a single powder tank 1, the other group comprises two powder tanks 1 arranged side by side, and the negative pressure pipeline 3 is connected with the two powder tanks 1 arranged side by side through the branch pipeline 6.
And pressure sensors are arranged in the negative pressure pipeline 3 and the powder tank 1, so that the internal pressure can be detected. In order to ensure the normal work of the negative pressure system, the emptying valve 7 is arranged on the negative pressure pipeline 3, when the negative pressure exceeds a set value, the emptying valve 7 can be opened to supplement air into the negative pressure pipeline 3, and the negative pressure value is reduced, so that the proper negative pressure is achieved, and the purpose of smoothly conveying materials into the tank body is achieved.
The primary filter 2 has two configurations:
1. the tank body is provided with a filter, the negative pressure system directly pumps vacuum of the powder tank 1, and materials directly enter the powder tank 1; the method is characterized in that: the filter area is large, and the filter can be used in occasions with high feeding speed (50-100 KG/MIN);
2. the tank body is externally connected with a vacuum feeding machine, and the materials are firstly fed into the vacuum feeding machine through negative pressure in the vacuumizing feeding machine and then fed into the powder tank 1 through a powder inlet; the method is characterized in that: the bulk density of the materials entering the powder tank 1 cannot be changed due to negative pressure; the material is not easy to bridge; the disadvantages are as follows: the filter area is small, and the filter is suitable for occasions with material conveying capacity less than or equal to 25 KG/MIN.
The vacuum filter core in the filter can adopt the following types: a pleated polyester coated filter cartridge; a polyester film-coated filter bag; sintering the filter element by using a carbon rod; PE sinters the filter core.
