Basket type filter with diversion baffle plate

Abstract

The invention discloses a blue-type baffle diversion filter, which includes a filter cartridge and a filter screen. On the inner wall of the liquid outlet side of the filter cartridge, an upper frame and a lower frame 9 are used to filter the round cup The cylinder is eccentrically installed and fixed. A guide baffle is installed on the outer circle of the upper and lower filter screen frames on the side of the liquid inlet in the filter cylinder. The two sides of the baffle are sealed with the inner walls of both sides of the filter cylinder. Sealed with the inner wall of the arc-shaped lower head of the filter cartridge, a liquid inlet buffer chamber is formed between the baffle plate and the side of the filter cartridge liquid inlet, and a liquid inlet and sewage outlet is provided on the lower head at the bottom of the buffer chamber. There is a liquid outlet and sewage outlet at the center of the bottom of the lower head, a pressure gauge is provided outside the liquid inlet and outlet respectively, and an exhaust valve is installed on the flange cover. The invention has the advantages of long service life of the filter screen, convenient opening of the flange cover plate, and large dirt holding capacity.

Description

Technical field: [0001] The invention relates to a liquid filter, in particular to a blue-type baffle diversion filter capable of diverting liquid in the filter to reduce the impact on the filter screen and prolong the service life. Background technique: [0002] In the existing liquid filter, the liquid enters the filter cartridge from the liquid inlet and directly impacts the filter screen, and is filtered on one side, which not only affects the filtration quality, but also causes the filter screen to wear out, frequent replacement, and increases the workload of the workers. In addition, the flange cover is inconvenient to open and install with bolts. The bottom of the filter cartridge is flat, and the dirt holding capacity is small. Frequent sewage discharge is required, which increases the maintenance workload. Invention content: [0003] The purpose of the present invention is to provide a blue-type baffle diversion filter with small liquid impact on the filter screen...

Problems solved by technology

[0002] In the existing liquid filter, the liquid enters the filter cartridge from the liquid inlet and directly impacts the filter screen, and is filtered on one side, which not only affects the filtration quality, but also causes the filter screen to wear out, frequent replacement, and increases the workload of the workers. Production cost, in addition, the flange cover is inconvenient to open and install with bolts, the bottom of the filter cartridge is flat, and the dirt-holding capacity is small, which requires frequent sewage discharge and increased maintenance workload
