Concentration filtering device

Abstract

The invention relates to a concentration filtering device, which comprises a filtering water tank, a filtering component, a back washing water tank, a water inlet pump and a back washing pump, wherein the back washing water tank is positioned under the filtering water tank, the filtering component comprises a plurality of mutually parallel tubular filter cores in vertical arrangement, a rotating valve is arranged under the filtering component and is formed by a valve body part and a valve core part through sealed anastomotic combination, the valve core part is positioned in the valve body part and can be driven to rotate, a plurality of position holes are respectively arranged at the side part of the valve body part and the outer side of the valve core part, the position holes arranged in the valve body part and the position holes arranged in the valve core part are in one-to-one correspondence, in addition, the position holes arranged in the valve body part are in one-to-one correspondence connection with a plurality of filter cores through filter core connecting pipes, one position hole in a plurality of position holes of the valve body is communicated with the back washing pump for forming a back washing passage, and the rest position holes are communicated with the back washing water tank for forming a water producing passage. The filtering device provided by the invention has the advantages that the energy consumption is low, the filtering effect is good, and in addition, the continuous water production can be realized.

Description

technical field [0001] The invention relates to a concentration filter device. Background technique [0002] With industrial progress and social development, water pollution is becoming more and more serious, which has become the number one environmental governance problem in the world. The existing sewage treatment system has problems such as complex operation, high operating cost, poor treatment effect, etc., and the equipment process is complicated. [0003] Chinese invention patent ZL200510093290.X discloses a comprehensive filtration sewage treatment process and equipment. Pumps, mud pumps, valves and other general parts are assembled. Among them, the filter water tank is a closed box with a water inlet on the top and a discharge port on the bottom. There is a filter layer between the water inlet and the drain. It is composed of quartz sand and filter cloth, the drain port is connected to the suction port of the self-priming pump, and the discharge port of the self-pr...

AI Technical Summary

Problems solved by technology

Although the sewage can be discharged up to standard after being treated by the process of this patent, the sewage system of this patent is relatively complicated, and it uses a self-priming pump to forcibly filter the sewage, which consumes a lot of energy; in addition, this equipment is the same as other traditional filtering devices , can only be carried out according to the intermittent mode of "water production-backwashing-water production-backwashing". Water production and backwashing are not carried out simultaneously, and continuous water production cannot be achieved
