Filter and working method thereof

Abstract

The invention discloses a filter and a working method thereof. The filter comprises a cavity, a cover and a filter medium, wherein the cover is provided with a through hole; a first part is arranged at the through hole and is located outside the cavity; the first part comprises a pipeline and a rotating piece; the pipeline is provided with an inlet and an outlet; the rotating piece is provided with a through hole and is arranged in the pipeline; when the rotating piece rotates, the inlet and the outlet of the pipeline are communicated or separated; a second part is arranged at the through holeof the cover and is located in the cavity; the second part comprises a container, a floatage piece, a connecting piece and a converting unit; the floatage piece and the connecting piece are arrangedin the container; the container is provided with a through hole; the connecting piece penetrates through the through hole of the cover and is connected with the rotating piece; the inner part of the container communicates with the through hole of the rotating piece; the converting unit converts the up-and-down movement of the floatage piece into rotation, the rotating piece rotates along with thefloatage piece, and the floatage piece and the connecting piece move relatively in the vertical direction. The filter provided by the invention has the advantages of good air exhaust effect and the like.

Description

technical field [0001] The present invention relates to liquid handling and in particular to filters and methods of operation thereof. Background technique [0002] The normal operation of some industrial equipment needs to avoid the air from entering the system. Usually, the designer will design a relatively extensive structure to solve this problem, such as installing an open pool to solve the problem before the air affects the equipment. These methods take up a lot of space, are costly, and are difficult to modify existing equipment. At present, there are still many devices that need to be manually exhausted regularly. Some methods can achieve automatic exhaust, but there are problems such as exhausting when the pressure is low, slow exhaust speed, and positive pressure at the exhaust position. [0003] Existing filter automatic exhaust methods mostly use the liquid level to control the opening and closing of the filter exhaust valve. In this method, liquid must be deliv...
