Negative pressure vacuum system for filtering solid particles and liquid

Abstract

A negative pressure vacuum system for filtering solid particles and a liquid comprises a first dust coarse filtration tank, a second dust coarse filtration tank, a first tee, a second tee, a vacuum tank, a first vacuum pump and a second vacuum pump, a gas inlet pipeline and a gas outlet pipeline are led out from the tank chamber of the vacuum tank, the first port of the first tee is communicated with the first gas outlet of the first dust coarse filtration tank, the second port of the first tee is communicated with the second gas outlet of the second dust coarse filtration tank, the third portof the first tee is communicated with the gas inlet pipeline of the vacuum tank, the first port of the second tee is communicated with the first gas inlet of the first dust coarse filtration tank, the second port of the second dust coarse filtration tank is communicated with the second gas inlet of the second dust coarse filtration tank, the third port of the second tee is externally connected with a user's vacuum use port, the pump ports of the first vacuum pump and the second vacuum pump are communicated with the gas outlet pipeline of the vacuum tank, the first vacuum pump is connected with the first vacuum filter and a first vacuum pump valve, and the second vacuum pump is connected with the second vacuum filter and a second vacuum pump valve. The system has the advantages of convenience in pipeline control, effectiveness in filtering dust particles, prolongation of the life of filter elements, improved system stability, high production efficiency and low cost.

Description

technical field [0001] The invention belongs to the technical field of filtering devices, and in particular relates to a negative pressure vacuum system for filtering solid particles and liquids. Background technique [0002] At present, the negative pressure vacuum system is widely used in machinery, chemical industry, medicine, food, electronics, metallurgy, petroleum and other fields, but the existing negative pressure vacuum system has poor stability, high failure rate, and needs frequent shutdown for maintenance, which affects production efficiency. One of the main reasons for maintenance is that the vacuumed container contains a considerable amount of impurities, mainly solid particles and liquid impurities. After these impurities enter the vacuum pump, the particles will accelerate the wear of the equipment, cause the seal to fail, and affect the vacuum degree, while the liquid The moisture in the vacuum will cause the equipment to rust and affect the service life of...

[0002] At present, the negative pressure vacuum system is widely used in machinery, chemical industry, medicine, food, electronics, metallurgy, petroleum and other fields, but the existing negative pressure vacuum system has poor stability, high failure rate, and needs frequent shutdown for maintenance, which affects production efficiency

One of the main reasons for maintenance is that the vacuumed container contains a considerable amount of impurities, mainly solid particles and liquid impurities. After these impurities enter the vacuum pump, the particles will accelerate the wear of the equipment, cause the seal to fail, and affect the vacuum degree, while the liquid The moisture in the vacuum will cause the equipment to rust and affect the service life of the equipment. Therefore, in order to ensure the comprehensive performance of the vacuum pump, the solid particles and liquid impurities in the circuit must be removed in time in actual use.

However, many companies now use complex and expensive multi-media filters, which are not only costly, but also very inconvenient to maintain.
