Automatic replacement device for filter screen of sewage microfilter

Abstract

The invention discloses an automatic replacement device for a filter screen of a sewage microfilter, which comprises a machine body, a rotating cylinder is arranged at the center of the top of the body, a first iron box is arranged on one side of the rotating cylinder, and the rotating cylinder is far away from One side of the first iron box is provided with a second iron box, the bottoms of the first iron box and the second iron box are slidably connected with the top of the body through sliding blocks, and the tops of the sliding blocks are all provided with sliding grooves . The top of the rotating block of the present invention is moved outwards, so that the rotating block rotates, the two sides of the filter screen are released from the fixed state of the groove, and then the locking block and the locking groove are connected to each other, and the telescopic blocks on both sides are fixed by the spring, and the new The filter screen is wound on the rotating cylinder, and the rotating block is separated from the fixing of the toggle bar, so that the rotating bar fixes the edge of the filter screen again, thereby realizing the replacement of the filter screen. It has the advantages of convenient installation, fast disassembly speed, and no need to stop the operation The advantages of ensuring the normal operation of the equipment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an automatic replacement device for a filter screen of a sewage microfilter. Background technique [0002] The filtration equipment of the microfiltration machine is fixed on the drum with a microporous screen to trap solid particles in the sewage and realize the purification device of solid-liquid separation. At the same time of filtration, it can pass the rotation of the drum and the force of backwash water , so that the microporous screen can be cleaned in time, and the solid can be easily separated from the sewage. [0003] However, a problem that traditional microfilters need to face is that after a period of filtration, the filter screen is easily blocked. Even if there is a recoil device on the top, the cleaning effect on the filter screen is very limited. Once a large-scale The clogging of the filter screen or the rupture of the filter screen will affect the fil...
