An easy-to-clean oil filter

Abstract

The invention discloses a conveniently cleaned oil filter which comprises a movable bottom plate, wherein a refined filtration cylinder and a coarse filtration cylinder are arranged at the upper end of the movable bottom plate; a controller is arranged on the front side of the refined filtration cylinder; a shunt box is arranged inside the refined filtration cylinder; a refined filter element is arranged at the upper end of the shunt box; a separating plate and a bearing plate are arranged inside the coarse filtration cylinder; a fixed coarse filter element is fixedly arranged between the separating plate and the bearing plate; a rotary filter element is arranged at the upper end of the bearing plate by virtue of a bearing; a residue outlet hole is formed in the upper end of the coarse filtration cylinder; a cleaning motor is arranged at the bottom in the coarse filtration cylinder; and a cleaning screw is arranged at the output end of the cleaning motor. The conveniently cleaned oil filter disclosed by the invention has the beneficial effects that the cleaning motor drives the cleaning screw to rotate, impurities filtered by the fixed coarse filter element are pushed out, and thefixed coarse filter element is prevented from being blocked; and the controller controls a solenoid control valve to be closed, so that the filtering operation of the corresponding refined filter element is stopped, the refined filter element stopping working is conveniently replaced, and non-stop replacement of the refined filter element is realized.

Description

technical field [0001] The invention relates to the technical field of oil purification and filtering devices, in particular to an oil filter that is easy to clean. Background technique [0002] The oil filter unit is a filter unit that removes solid impurities and moisture in impure oil by means of pressure filtration or vacuum evaporation-pressure filtration. The oil filter is mainly used to improve the insulation performance of electrical oil and the purity of lubricating oil. The high-efficiency oil filter is mainly used for the purification and regeneration of turbine oil and lubricating machinery oil in power plants, power stations, industrial and mining enterprises. In order to improve the filtration effect, the combination of coarse filtration and fine filtration is often used. [0003] The applicant found that there are at least the following technical problems in the prior art: when the current oil filter device is used for coarse filtration, long-term use is lik...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an easy-to-clean oil filter in order to solve the above problems, so as to solve the problem that when the current oil filter device in the prior art performs coarse filtration, long-term use is likely to cause blockage of the coarse filter element and inconvenient cleaning; When replacing the fine filter element, it needs to be shut down for replacement, which affects technical problems such as the filtering effect and filtering efficiency of the device
