Bag type filtering equipment and using method thereof

Abstract

The invention discloses bag type filtering equipment and a using method thereof. The equipment comprises a support, a water inlet in the upper end of the support, a motor, a scraper, a fixing shaft onthe right side of the scraper, a plurality of springs on the scraper, a plurality of gears fixed to the support, fixing shaft rods distributed on the upper side and the lower side of a filter screen,a 200-mesh modular filter screen with the mesh number capable of being changed, a 400-mesh modular filter screen, a 600-mesh modular filter screen, chains embedded in the filter screens and having the same number as the gears, modular water baffles distributed on the two sides of the filter screens, filter screen guide grooves distributed in the upper sides and the lower sides of the filter screens, and a water outlet in the lower end of the support. Compared with the prior art, the bag type filtering equipment has the advantages of continuous filtration, large filtration capacity, low cost,simplicity in operation and zero emission.

Description

technical field [0001] The invention relates to the field of environmental protection technology, in particular a bag filter device. Background technique [0002] As a stable and economical filtering equipment for separating impurities, the filter is widely used in many fields such as electric power, steel, environmental protection, food, medicine, petrochemical, electronics and automobiles. Most of the filtering equipment is quartz sand and cotton core filtering equipment now. Reverse osmosis equipment such as microfiltration, nanofiltration and ultrafiltration require high grades. However, when these equipments filter sewage, they have the disadvantages of not being able to filter continuously or having a limited amount of filtration, and high cost, which seriously affects the development of filtration equipment. Therefore, It is urgent to invent a filter device capable of continuous filtration with large filtration capacity, low cost, simple operation and high efficiency ...
