Abstract

The invention discloses a control system for a high-precision liquid filter. The control system comprises a filter element connecting rod fixedly connected with a filter element, a spring, an upper sensor, a lower sensor, a contact and a control device for controlling the filter to start and turn off backwashing, wherein the filter element connecting rod is fixedly connected with the middle part of the spring; the upper sensor is positioned above the spring and the lower sensor is positioned below the spring; the filter element connecting rod is fixedly connected with the contact; and the upper deformation of the spring drives the contact to contact the upper sensor to trigger the control device to start the backwashing, and the lower deformation of the spring drives the contact to contact the lower sensor to trigger the control device to turn off the backwashing. The control system for the high-precision liquid filter has the advantages that: on the premise that the pressure of the filter element is in direct proportion to the deformation of the spring, the blockage of the filter element is accurately monitored, and the backwashing is started when the filter element is blocked and needs the backwashing, so that the consumption of filtered liquid during the backwashing is effectively reduced and the capacity of the filter is improved.

Description

technical field [0001] The invention relates to the field of precision filtration, in particular to a control system for a high-precision liquid filter. Background technique [0002] At present, in the field of liquid filtration, there is a situation that the intelligence of the backwash control system of the filter is relatively low. Since the filter needs to be backwashed after use, and the liquid used for backwashing is the filtered liquid, the amount of filtered liquid used for backwashing is too large, resulting in a low production capacity of the filtered liquid. [0003] At present, there are mainly the following defects: [0004] 1. In the case of using multiple filters, there is no control to determine which filter to start backwashing during backwashing, and backwashing requires the use of filtered high-precision liquid, so each filter element needs to be used for backwashing For cleaning, a large amount of high-precision liquid is used. [0005] 2. When perform...
