Filter

Abstract

The invention discloses a filter, which is composed of a body, a sewage valve, a filter screen, a scraper, an inlet, an electric reducer, a pressure sensor, a signal converter, an outlet, a sealing top cover and a bracket, and the bracket is three The bottom edge of the uniform connector body, the center position of the bottom of the drain valve connector body, the center position inside the filter screen connector body, scrapers are set on both sides of the filter screen, the upper left side of the inlet connector body, and the lower right side of the outlet connector body , the upper right outside the signal converter connector body, the pressure sensor is located next to the signal sensor, the sealing top cover is connected to the top of the body through nuts, and the electric reducer is connected to the top of the sealing top cover. The invention improves the connection structure of the filter screen in the filter, so that when the filter is flushing the filter screen, the filter screen can realize the circumferential rotation movement, so that the cleanliness of the filter screen is higher, and the residue left in the filter screen is reduced. impurities to ensure the normal working efficiency of the filter.

Description

technical field [0001] The invention belongs to a filtering device, in particular to a filter. Background technique [0002] When the filter is working, water enters from the water inlet, passes through the fixed platform and the positioning platform, and flows into the filter screen. After being filtered by the filter screen, the impurities remain in the filter screen, and the filtered water will leak out from the filter screen. When the water flows out from the water outlet, there will be more and more impurities in the filter screen under long-term working conditions. When flushing the filter screen, water will enter from the water outlet, and then flow inward from the outside of the filter screen to achieve the purpose of cleaning the filter screen. However, the filter screen will not rotate during the flushing process. Some impurities will remain in the corners that are difficult to clean. The water will not rush into the corners, and the impurities in the filter scree...

AI Technical Summary

Problems solved by technology

However, the filter screen will not rotate during the flushing process. Some impurities will remain in the corners that are difficult to clean. The water will not rush into the corners, and the impurities in the filter screen will not be cleaned well. The long-term accumulation will affect the filter screen. Filtration work, making the efficiency of the entire filter decline
