Novel efficient filtering plate

Abstract

The invention relates to a novel efficient filtering plate which comprises a filtering plate body. A plurality of filtering holes are formed in the filtering plate body. A first supporting column and a second supporting column are arranged at the bottom of the filtering plate body. The filtering holes include the central filtering hole and the filtering holes annularly distributed around the central filtering hole. A plurality of flow blocking protrusions are arranged in the filtering holes and include the vertical protrusions, the first protrusions and the second protrusions, wherein each first protrusion and the corresponding second protrusion are located on the two sides of the corresponding vertical protrusion in staggered mode respectively and both connected with the vertical protrusion obliquely. A plurality of third protrusions are arranged on the second protrusions and provided with fourth protrusions. Small particle impurities in fluid can be easily filtered away, the filtering holes are prevented from being blocked or blocking fluid, and use convenience is improved.

Description

technical field [0001] The invention relates to a filter plate, in particular to a novel high-efficiency filter plate. Background technique [0002] The filter plate is an indispensable device on the conveying medium pipeline. It is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, fixed water level valve or other equipment to eliminate impurities in the medium to protect the normal operation of the valve and equipment. use. When the fluid passes through the filter cartridge equipped with a filter plate, its impurities are blocked, and the clean filtrate is discharged from the filter outlet. When cleaning is required, just take out the detachable filter cartridge and reinstall it after treatment. Therefore, it is extremely convenient to use and maintain.

Problems solved by technology

[0003] However, the filter plate in the prior art generally adopts a plate-shaped structure and is equipped with a filter screen to achieve filtration. It is difficult to install tightly, and it is easy to loosen. The mesh filter effect is not good, and small particles of impurities are usually difficult to filter. It is easy to cause blockage, block fluid flow, frequent and complicated disassembly and cleaning, which is not conducive to use
