Description

Technical Field

[0001] The utility model relates to the technical field of liquid feeding, in particular to a stone blocker for liquid feeding. Background Art

[0002] When the centrifugal pump works in an environment with poor conditions, there are many debris such as iron filings and gravel in the water. The centrifugal pump is easily blocked by impurities, resulting in flow interruption and vacuum. Therefore, the water inlet of the existing centrifugal pump is generally connected with a filter screen, through which the clean water is filtered to prevent blockage. However, if the water supply route is long or the inner wall of the pipeline is rusted and corroded, if the water inlet is only covered with a filter screen, the liquid may be contaminated again in the pipeline. When the re-contaminated liquid enters the centrifugal pump, it will still threaten the normal operation of the centrifugal pump.

[0003] The purpose of the utility model is to improve and innovate the shortcomings and problems existing in the background technology, and to provide a simple structure suitable for filtering and sedimentation in the process of liquid feeding. The technical solution of the utility model is to construct a filter housing, a filter screen, and a strong magnet, wherein the end of the main channel tube for sucking fluid is provided with a shell with filter holes, and a reverse flushing auxiliary channel tube is arranged side by side with the main channel tube, and the countercurrent auxiliary channel tube extends into the shell. Holes are evenly distributed around the tube body.

[0004] The utility model adopts a closed overall structure. When it is applied to the front end of various other pressure pipes that require the installation of suction filters, it can reduce the failure time of the suction filter channel being blocked and shut down for maintenance. Since the utility model is provided with an auxiliary channel pipeline with a backwashing function, while meeting the opening rate required for the optimal economic flow rate of the fluid in the main channel of the suction filter, it can greatly reduce the overall structure of the suction filter; it can adapt to fluids with high viscosity or more insoluble particles. For various other different suction and filtration fluids, countercurrent reverse sedimentation filters with various closed overall structures can also be constructed using different materials according to the design of the utility model, and the final use effect remains unchanged.
