Abstract

The utility model discloses a closed fluid impurity filter. The closed fluid impurity filter comprises a box body, a filter top, a filter cover, a shaft, a shaft sleeve, a bolt buckle, a short drain pipe, a filter net, and a positioning groove. The box body is provided with an inspection port and an overflow port; the upper part of the box body is provided with a filter top, and the filter top and the box body are connected by bolts; the shaft sleeve on the filter cover is directly placed on the shaft on the filter top; the filter screen is removed The water flow enters the opening in the direction, and the other surfaces are completely closed with a filter screen; when the filter screen is installed, insert the angle steel in the filter screen into the positioning groove of the filter cover. The utility model has the advantages of effectively filtering the sundries in the low-pressure fluid and preventing the water pump from being blocked and damaged. At the same time, the filter cover is more convenient to open and close. The filter adopts a U-shaped structure to achieve large-area filtration with low resistance. It is convenient to remove debris inside the filter and replace the filter.

Description

A closed fluid impurity filter

technical field

The utility model relates to a low-resistance fluid impurity pipeline filter in mine drainage engineering and water intake engineering, in particular to a closed fluid impurity filter.

Background technique

Fluid impurity filter devices are usually accompanied by the problems of large resistance and difficult cleaning and replacement. Therefore, although the water quality is poor in mine drainage projects and water intake projects at present, the water contains many sundries, and there is no water inlet pipeline filtering device. Debris can easily cause wear, blockage or even damage to the pump, bringing unsafe factors to the project.

Contents of the invention

The purpose of the utility model is to provide a closed fluid impurity filter to solve the problem of foreign matter entering the fluid system.

The technical scheme of the utility model is: a closed fluid impurity filter, which includes a box body, a filter top, a filter cover, a shaft, a shaft sleeve, a bolt buckle, a short pipe for draining water, and a filter net , positioning slot, the box body is provided with an inspection port and an overflow port; the upper part of the box body is provided with a filter top, and the filter top and the box body are connected by bolts; the shaft sleeve on the filter cover is directly placed on the shaft on the filter top ; Except for the opening in the direction of water flow into the filter screen, the other surfaces are completely closed with the filter screen; when the filter screen is installed, insert the angle steel in the filter screen into the positioning groove of the filter cover. The filter cover can rotate around the filter top through the shaft and the shaft sleeve. The filter cover and the filter top are fixed with bolt buckles, the bolts are buckled on the nuts and the nuts are loosened, and the bolt buckles are broken off to open the filter. The filter screen is a U-shaped structure. The filter is installed in the middle of the pipeline through the inlet and outlet flanges.

The utility model has the advantages that it can effectively filter the sundries in the low-pressure fluid, and prevent the water pump from being blocked and damaged. At the same time, the filter cover is more convenient to open and close, and the filter screen can be pulled out directly to achieve large-area filtration, with low resistance, and it is convenient to remove debris inside the filter and replace the filter screen.
