Filter

Abstract

The invention discloses a filter, which comprises a drain plate, wherein the drain plate divides a filter cylinder into two parts of which the upper part is high and the lower part is low; the middle part of the upper part cylinder is provided with a column type filter core, the bottom end of the column type filter core is connected with the drain plate, and the top end of the column type filter core is connected with a press plate by a filter core plug; and the bottom surface of the lower part cylinder is connected with support legs by a support plate. The filter is characterized in that both sides of the lower part of the upper part cylinder are provided with a water inlet respectively, and a water outlet is arranged below the support plate of the lower part cylinder; and the edge of the upper part of the upper part cylinder is provided with a convex edge connected with an upper cover plate with vent holes through a hanging rod mechanism, and the upper cover plate is connected with the edge of the upper part of the upper part cylinder and tightly pressed against the press plate. The filter has the advantages of long service life of the filter core, high working efficiency of the filter and convenient replacement of the filter core in maintenance.

Description

technical field [0001] The invention relates to a filtering device which is used in all pure water and low salt water industries such as electronics, pharmacy, thermoelectricity, and chemical industry, and uses the micropores of the filter element to intercept particulate matter in the water and filter the water. Background technique [0002] At present, a kind of precision filter (0.1μ, 0.2μ, 0.22μ, 1μ, 3μ, 5μ, 10μ, etc.) used in the water treatment industry is in the form of water inlet on one side and water outlet on the other side. Tighten (if attached figure 1 ). There are following deficiencies in this kind of filter: [0003] 1. One side of the filter enters water and the other side exits. There is a phenomenon of hydraulic impact on the filter element when it is turned on and off. The filter element will be damaged due to hydraulic impact before the service life is reached; [0004] 2. When replacing the filter element, it is difficult to press down the pressure p...

AI Technical Summary

Problems solved by technology

[0003] 1. One side of the filter enters water and the other side exits. There is a phenomenon of hydraulic impact on the filter element when it is turned on and off. The filter element will be damaged due to hydraulic impact before the service life is reached;

[0004] 2. When replacing the filter element, it is difficult to press down the pressure plate, which requires a lot of manpower; often when the pressure plate is pressed down, the filter element is skewed, and the pressure has to be re-applied, which is time-consuming and laborious;

[0005] 3. It is necessary to use a tool to loosen the plug for exhausting. It is inconvenient to exhaust, the operation is dangerous, and the plug may be flushed out
