A filter system and its application

Abstract

The invention discloses a filtering system. The filtering system comprises a box body, a hollow filter element, an air inlet baffle plate, a hollow filter element open end baffle plate, a support frame and a hollow filter element sealed end baffle plate, wherein the box body is provided with an air inlet and an air outlet; the hollow filter element is arranged in the box body, and the outer side of the hollow filter element is communicated with the air inlet, and one end of the inner side of the hollow filter element is communicated with the air outlet; the air inlet baffle plate and the inner surface of the box body cover an air inlet at interval, and the air inlet baffle plate and the outer peripheral surface of the hollow filter element are spaced at interval; the periphery side of the hollow filter element open end baffle plate is tightly connected with the inner wall of the box body, and the hollow filter element open end baffle plate is provided with a hole communicated with an air outlet within the inner diameter range of the hollow filter element; the support frame is supported on the inner side wall of the hollow filter element; the hollow filter element sealed end baffle plate is connected with the support frame. The filtering system provided by the invention can effectively filter dust during the vacuumization process without affecting the vacuumization efficiency, can prevent dust from entering a vacuum pump, prolongs the service life of the vacuum pump, improves the safety performance of the vacuum pump, reduces the using cost of the vacuum pump, and guarantees the melted alloy quality.

Description

technical field [0001] The present invention relates to a filtration system, especially, the filtration system can be applied to a vacuum melting furnace, which is a device for producing hydrogen storage alloy ingots in the production of hydrogen storage alloys. Background technique [0002] The current filtration system is difficult to apply to the industrial process of vacuuming, for example, it is difficult to apply to the process of vacuum melting furnace. [0003] In the production of hydrogen storage alloys, vacuum melting furnaces are used to produce hydrogen storage alloy ingots. During the vacuuming process, there are the following disadvantages: during the vacuuming process, the air in the furnace body is pumped out by the vacuum pump, and the dust in it is accumulated in the vacuum pump, causing the oil pollution of the vacuum pump, affecting the lubrication effect, and causing the failure of the vacuum pump and components. The damage of the vacuum pump shortens ...

AI Technical Summary

Problems solved by technology

During the vacuuming process, there are the following disadvantages: during the vacuuming process, the air in the furnace body is pumped out by the vacuum pump, and the dust in it is accumulated in the vacuum pump, causing the oil pollution of the vacuum pump, affecting the lubrication effect, and causing the failure of the vacuum pump and components. The damage of the vacuum pump shortens the service life of the vacuum pump and greatly reduces the efficiency of vacuum pumping

[0004] In the prior art, it is always desired to overcome the above-mentioned shortcomings, however, there has been no vacuum melting furnace provided with a filtration system

One reason is that the technology is not considered feasible, the other reason is that it is not considered necessary
