Abstract

The invention discloses a multi-filter element filter. A motor is installed on the top cover of a multi-filter element filter with a support. The lower end of the seal rotates through the filter element mounting plate and connects a backwash pipe that rotates with the rotating shaft downwards with a tee in the middle of the liquid inlet chamber. A backwash pipe is connected to the bypass of the tee, which can be used with any filter element connection hole on the mounting plate. The bypass pipe connected to the suction cup is connected to the lower end of the backwashing pipe with a blowdown valve connected to the outside of the lower end head, and a manual blowdown valve is installed on the other side of the blowdown valve on the lower head. A control cabinet is installed on the outer wall of the filter housing, a differential pressure sensor is installed on the outer wall of the filter housing above the liquid outlet pipe, and an exhaust valve communicating with the inside of the filter housing is installed on one side of the top cover. With backwashing function, it can effectively improve work efficiency and reduce maintenance amount and cost.

Description

Technical field: [0001] The invention relates to a filter, in particular to a multi-filter core filter with backwashing function. Background technique: [0002] The existing multi-filter element filter is to install a filter element mounting plate higher than the liquid inlet pipe and lower than the liquid outlet pipe in a vertical filter housing, and at least four filter elements are evenly distributed in the middle of the surrounding radius along the center of the circle on the mounting plate. The connection holes of the filter elements are respectively installed with a filter element on the connection holes of each filter element. On the hanging plate connected to the cover, an exhaust pipe is installed on the top cover, and a sewage discharge pipe is led out from the lower head of the filter housing. This structure obviously has the advantages of large filtration area and wide application range. However, the main defect is that each filter element has a small dirt hold...
