Filter cylinder assembly of high-pressure back-washing filter station

Abstract

The invention discloses a filter cylinder assembly of a high-pressure back-washing filter station. The filter cylinder assembly comprises a shell and a filter core, wherein the filter core is arranged inside the shell; an end cover is arranged at the upper end of the filter core; a screw plug is fixedly arranged on the inner side of the upper end of the shell; a press cover is arranged at the upper end inside the screw plug; a rapid locking mechanism is arranged between the press cover and the screw plug; the end cover extends into the lower end inside the screw plug; the end cover is located below the press cover; a concave hole is arranged in the end cover; a screw rod is arranged at the center of the press cover in a penetrating manner; and the lower end of the screw rod extends into the concave hole and props against the end cover. The filter cylinder assembly provided by the invention has the advantages in that the screw rod is screwed for a certain angle, so that the front end of the screw rod departs from an inner hole, and at the moment, the upper surface of a locking block departs from the upper surface for tightly pressing an annular groove; and the press cover is rotated for the certain angle, so that the locking block is aligned with a gap, and at the moment, the press cover can be taken out from the screw plug, and the screw rod is taken out with the press cover, so that the filter core is taken out from the shell, thus being very convenient to replace.

Description

technical field [0001] The invention relates to a high-pressure backwash filter station, in particular to a filter cartridge assembly of a high-pressure backwash filter station. Background technique [0002] During the use of the hydraulic system, the failures caused by medium pollution account for the majority of system failures. With the automation of the working process of the parts, the parts of the hydraulic system are becoming more and more precise, and the failure rate of the required components is getting lower and lower. Therefore, Improving the filtration accuracy of the system medium and preventing the excess in the medium from entering the working parts are important means to improve the reliability of the hydraulic system. [0003] The high-pressure filter station with backwashing function is a medium cleaning device specially designed to ensure the long-term reliable operation of the hydraulic system. The high-pressure filter station is installed at the outlet...

AI Technical Summary

Problems solved by technology

When the filter element needs to be replaced or repaired, it is necessary to unscrew the filter element from the housing, which is troublesome to operate

At the same time, threaded connection is easy to cause rust or jamming
