A dirty oil filter cartridge

Abstract

The invention discloses a dirty oil filter barrel. The dirty oil filter barrel comprises a barrel body, and an oil inlet and an oil outlet which are formed in the upper and lower ends of the barrel body; a separation plate is mounted in the barrel body; flow leakage hole groups are formed in the two ends of the separation plate; the dirty oil filter barrel further comprises a supporting base fixed in the barrel body; a movable rod is arranged in the supporting base in a sliding manner; a groove is formed in the lower end of the supporting base; the lower end of the movable rod is connected with the bottom of the groove by a spring; the middle of the lower end face of the separation plate is inwards concave; each flow leakage hole group comprises a flow leakage hole A, a flow leakage hole B and a flow leakage hole C; and a plurality of baffles which are matched with the flow leakage holes A, the flow leakage holes B and the flow leakage holes C are fixedly arranged in the middle of the movable rod. The control of flow of oil liquid in the barrel body is realized by the up-down adjustment of the movable rod, so that the impact on the barrel body by the oil liquid is reduced and the aim of protecting a filter is realized.

Description

technical field [0001] The invention relates to a filter device, in particular to a dirty oil filter cartridge. Background technique [0002] At present, the oil filter is widely used in the purification of hydraulic oil, hydraulic transmission oil, gear oil, gasoline engine oil, diesel engine oil, compressor oil, refrigeration oil and heat treatment oil, etc. The oil filter can quickly remove the moisture in the oil , gas and mechanical impurities, flash evaporation to remove light acids, light hydrocarbons, etc., thereby improving the quality of the oil, restoring the performance of the lubricating oil, and ensuring the normal operation of the power system, hydraulic system, and lubrication system. The filter element assembly of the pass-through filter in the prior art basically includes two parts, namely the filter frame and the filter screen, which are welded by melting tin to form the filter element assembly.

Problems solved by technology

The filter element assembly of the pass-through filter in the prior art basically includes two parts, namely the filter frame and the filter screen, which are welded by melting tin to form the filter element assembly. The filtration accuracy of the filter element assembly is 80 mesh. When the high-pressure liquid passes, the medium Containing tiny metal particles will enter the hydraulic system through the filter screen, causing pollution to the hydraulic valve and jack, reducing the service life of the valve and jack, and even malfunctioning due to the sealing failure of the hydraulic valve, resulting in personal and equipment accidents

[0003] And the traditional primary filtration for industrial oil usually uses ordinary filters to deal with large-diameter impurity particles in industrial oil, but during the injection process of industrial oil, the high-speed water flow has a greater impact on the filter. The large impact, and the impurity particles flowing at high speed will cause serious wear to the parts in the filter, which greatly reduces the service life of the filter. The solution adopted in the prior art is to directly adjust the industrial filter through the valve. The injection rate of the oil, but the mechanical valve needs to be manually adjusted continuously, which increases the labor load of the staff and greatly reduces the filtration efficiency of industrial oil
