Description

Filter screen and filter screen mounting structure

Technical Field

The utility model relates to a filter screen mounting structure technical field especially relates to a filter screen and filter screen mounting structure.

Background

The filter is an indispensable device on a medium conveying pipeline and is usually arranged at the inlet end of a pressure reducing valve, a pressure relief valve, a constant water level valve and other equipment of a squaring filter. The filter consists of a cylinder body, a stainless steel filter screen, a pollution discharge part, a transmission device and an electric control part. After water to be treated passes through the filter cylinder of the filter screen of the filter, impurities are blocked, when the water is required to be cleaned, the detachable filter cylinder is taken out, and the water is treated and then is filled in again, so that the water treatment device is very convenient to use and maintain.

When the filter works, water to be filtered enters from the water port, flows through the filter screen, enters a pipeline required by a user through the outlet to perform process circulation, and particle impurities in the water are intercepted inside the filter screen.

The traditional mode that the filter cylinder is directly inserted is adopted in the installation of the filter cylinder to position the filter cylinder in the installation shell, and when the filter cylinder is subjected to large water flow impact force, the filter cylinder is easy to shake, so that a small amount of media to be filtered can easily pass through a gap, and the media do not directly enter a pipeline through the filter cylinder, so that the filtering effect is poor, and the using requirements of personnel can not be met.

To solve the above problems, a filter screen and a screen mounting structure are proposed.
