Automatic control arrangement of mechanical filter

Abstract

The invention provides an automatic control device for mechanical filter, belonging to an automatic control device, which comprise of a pressure sensor in liquid inlet pipe, another pressure sensor in liquid inlet cavity of mechanical filter, and a third pressure sensor in liquid outlet cavity, every pressure sensor being equipped with the carry-in terminal of micro processor, the liquid inlet pipe being linked to an outlet tube by a recoil pipe which is equipped with a recoil magnetic valve, the outlet being equipped with a outlet magnetic valve and the draining-pipe equipped with a blowoff magnetic valve, and every magnetic valve being equipped with the output end of micro processor. The automatic control device can monitor the stoppage state of mechanical filter continuously and exactly and it also can clear the stoppage immediately and automatically according to the stoppage state.

Description

technical field

[0001] The invention provides an automatic control device, especially an automatic control device for a mechanical filter. Background technique

[0002] In industrial production and daily life, mechanical filters are often used for filtration. During the use of the filter, there is a cycle of "normal use - gradually clogging - clogging - unclogging (backflushing) - normal use". Since the mechanical filter generally has a metal shell, it is difficult for people to observe the internal situation, so people have not found a monitoring method and device for timely and accurately judging the clogging of the mechanical filter, and can only conduct passive monitoring based on experience. management and control. Under normal circumstances, it is not until the mechanical filter is completely blocked that technical measures such as unclogging can be found and taken, and at this time it will have a serious impact on normal production and life. ...
