Gas-liquid-solid three-phase cyclone separation device with automatic exhaust valve and separation method thereof

Abstract

The gas-liquid-solid three-phase cyclone separation device comprises the automatic exhaust valve, a return oil flow dividing cavity, a cyclone body and a filter element, the return oil flow dividing cavity is located at the lower end of the automatic exhaust valve, a head upper top plate in the return oil flow dividing cavity is connected with the lower end of an exhaust valve lower shell in the automatic exhaust valve, and the lower end of the cyclone body is connected with the filter element. The cyclone body is located in the oil return flow dividing cavity, the upper end of a mixing cavity body in the cyclone body is connected with an upper top plate of an oil return cavity body, the filter element is located at the lower end of the cyclone body, and a conical flow guide pipe of the cyclone body is connected with the interior of a one-way valve in the filter element. Under the swirling action of the swirler main body, gas-phase impurities enter the automatic exhaust valve to be discharged, and solid-phase impurities sink into the filter element connected with the lower end of the swirler main body for secondary filtration of oil. By means of the automatic exhaust valve, gas-phase impurities are discharged in a one-way mode, solid-phase impurities are separated, three-phase separation is achieved, the separation cost is reduced, and the separation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic oil filtration equipment, in particular to a gas-liquid-solid three-phase cyclone separation device with an automatic exhaust valve and a separation method thereof. Background technique [0002] Hydraulic transmission is widely used in construction machinery, aerospace, mobile robots and other fields; with the rapid development of China's manufacturing industry, high pressure, high speed and high reliability have become important trends in the development of hydraulic technology. The pollution of hydraulic oil is the main source of hydraulic system failure, which will cause serious damage to hydraulic components and systems. At present, 75-90% of the faults in the hydraulic system are caused by hydraulic oil pollution. During the operation of the hydraulic system, the wear of components, the mixing of external pollutants and the gas precipitation under pressure changes are the main sources of h...

AI Technical Summary

Problems solved by technology

The core element of the filter, the filter element, has a short service life and is difficult to clean for reuse, resulting in a certain degree of waste of resources

At the same time, the current filter device basically does not have the function of removing gas, and the air mixed in the oil is easy to re-enter the hydraulic system through the filter element
