External pressure type filter element housing

Abstract

The invention discloses an external pressure type filter element housing. The external pressure type filter element housing comprises a filter element housing body, wherein a water inlet pipe is arranged at the outer wall of the filter element housing body and is communicated with an inner cavity; a water outlet pipe is arranged at the bottom part of the filter element housing body and is communicated with the inner cavity; an end cap for sealing is arranged at the upper end opening of the filter element housing body; a fixed support plate is clamped into the inner cavity of the filter elementhousing body; a water production pipe longitudinally penetrates through the fixed support plate; a filter element is sheathed at the exterior of the water production pipe; a filter element fixing device is arranged at the upper end of the water production pipe and is used for fixing the filter element. The external pressure type filter element housing has the advantages that the external pressuretype filter element can be firmly and fixedly arranged in the filter element housing without any special tool; the positioning is accurate, the sealing property is good, and the problem of failure toreach standard of water quality due to poor sealing property is effectively solved; by utilizing a buckle structure to connect, the filter element housing can be quickly installed and detached, and the time is shortened.

Description

technical field [0001] The invention belongs to a filter assembly, in particular to an external pressure filter core shell. Background technique [0002] The filter element is the most important part of the filter, which can purify the polluted medium and achieve the clean state required for production and life. In the water filtration industry, filter elements are used in a very wide range, ranging from industrial production to small drinking water treatment, all of which cannot be separated from filtration technology. The filter element can be divided into two types: external pressure type and internal pressure type according to the different water inlet methods. [0003] The external pressure filter element is that the raw water is pressurized and flows outside the filter element, and flows out from the inside of the filter element after passing through the filter material. In order to ensure that the quality of the effluent reaches the standard, it is necessary to ensu...

AI Technical Summary

Problems solved by technology

The installation of the traditional external pressure filter element is to use a special tool to press the filter element with the end cover and fix it in the center of the shell. If the force is not properly controlled, the sealing ring of the filter element will become loose, the filter element will not be fixed in place, and the quality of the effluent water will not be good. ensure
