Dual-channel intelligent filtering system and method

Abstract

The invention discloses a double-channel intelligent filtering system which comprises a control unit, a first water inlet valve mounted on a first filtering channel, a second water inlet valve mounted on a second filtering channel, a first pressure sensor and a flow meter which are mounted on a water inlet channel, and a second pressure sensor mounted on a water outlet channel, the second water inlet valve, the first pressure sensor, the second pressure sensor and the flow meter are electrically connected with the control unit. The two filter channels are matched for use, the uninterrupted requirement is met, meanwhile, the pressure sensor is matched for detecting the water pressure value, the passing ability of the filter element is obtained, and then the filter element is used to the maximum degree.

Description

technical field [0001] The invention relates to the field of filtering, in particular to a dual-channel intelligent filtering system and method. Background technique [0002] In the current field of biological and medical research, experimental animals are widely used for various medical drug research. In order to make the results of various research experiments accurate and reproducible, there are strict requirements on the quality of drinking water for experimental animals. Drinking water for experimental animals Previously, water had to be strictly sterilized by filtration to ensure the health of experimental animals and prevent the spread of bacteria. [0003] The existing drinking water filtration method is to install a filter on the filter pipe to filter the water quality. This method can effectively realize the treatment of drinking water. Since the filter element has a service life, a single filter channel reaches the service life of the filter element. At the same ...

Problems solved by technology

[0003]The existing drinking water filtration method is to install a filter on the filter pipe to filter the water quality. This method can effectively realize the treatment of drinking water, because the filter element It has a service life. When a single filter channel reaches the end of its service life, the pipe can only be cut off for replacement, which cannot meet the needs of uninterrupted use. At the same time, the existing filter element cannot be tested in terms of service life, and can only be manually used according to the use time. evaluation, and the existing filter cannot simultaneously solve the contradiction between the high flow rate and the low passability of the old filter element, so that the filter element will be replaced once the output pressure is unstable, resulting in the filter element being unable to be fully used
