Rotating wheel core-changing type filter with blockage alarm function

Abstract

The invention discloses a rotating wheel core-changing type filter with a blockage alarm function, which comprises a pipe body, slow flow grooves are formed in two ends of the pipe body, circulation grooves are formed in one sides, close to each other, of the two slow flow grooves, a filter groove is formed in the outer side wall of the pipe body, and a core-changing wheel is hermetically and rotatably mounted in the filter groove. A plurality of filter element holes are annularly formed in the core-changing wheel at equal intervals, an arc-shaped groove is formed in the position, located at the hole end of each filter element hole, of the core-changing wheel, two pressure dividing pipes are symmetrically inserted into the outer side wall of the pipe body, and a detector is installed on the outer side wall of the pipe body. According to the invention, a new filter core column can be quickly replaced and an old filter core column can be detached by rotating the core-changing wheel, theblockage state can be detected in real time through the pressure dividing pipe and a detection rod, the blockage can be timely alarmed through a radial piezoelectric pipe and an arc-shaped detection electric sheet, an external power supply is not needed for power supply, and the filter is more energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the field of filters, in particular to a rotary core-changing filter with a clogging alarm function. Background technique [0002] Pipeline filter is one of the important equipment in the water delivery system of water conservancy projects. The pre-pipeline filter can filter large impurities such as sediment in the water, and the post-pipeline filter can filter small microorganisms and germs in the water. Therefore, , The pipeline filter is an important equipment to ensure the quality of water delivery, and the filter element of the pipeline filter needs to be replaced in time due to long-term use and blockage. [0003] The existing filter cannot be reminded in time when the blockage is serious, and it is inconvenient to go through complicated steps such as closing the water valve, disassembling the filter, removing the filter element, replacing the filter element, installing the filter, and opening the water valve when replaci...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings of the prior art that it cannot be reminded in time when the blockage is serious, and the operation of replacing the filter element is cumbersome, and proposes a rotary core-changing filter with a blockage alarm function
