Automatic vortex-type filtering device

Abstract

An automatic vortex-type filtering device comprises a tank body (1) with fiber balls, a water inlet pipe (2) and a drain pipe (3), and is characterized in that at least two groups of backwashing inlets (g) are formed on the tank body (1); each group of backwashing inlets (g) is at least connected with two annular backwashing water pipes (4) which are circumferentially arranged along the inner wall of the tank body; water outlets of the two annular backwashing water pipes are oppositely formed, so that the directions of water flowing out of the two backwashing water pipes (4) are opposite and thus a vortex is formed inside the tank body; and a valve-controlled backwashing water outlet (d) is formed on the lower part of the water inlet pipe (2). The automatic vortex-type filtering device uses two-way vortex-type backwashing water intake to replace the conventional backwashing mode of mixing fiber balls of a mixer; electricity loss is avoided, thus meeting requirements on energy conservation and emission reduction; the internal structure of the filter is simplified, so that the cost is reduced and maintenance is convenient; the sealing effect is good; and the automatic vortex-type filtering device can work for a long time.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a device for treating industrial water by using fiber balls, in particular to an automatic swirling filter device. Background technique [0002] At present, in the traditional fiber ball filter, the raw water enters from the upper part and flows out from the lower part after being filtered by the fiber ball, such as figure 1 As shown, because the fiber ball has the characteristics of easy compression and large void ratio, the fiber ball will be crushed during filtration. [0003] After the equipment has been in operation for a period of time, backwashing is required when the amount of dirt intercepted by the fiber ball reaches the design value. Since the filter material of the fiber ball is compressed and forms a block during filtration, it is difficult to complete the cleaning work only by backwash water pressure. The conventional method is Set up a blender on top of the filter, such...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems that the existing filter using fiber balls for water treatment needs to use the agitator to realize the disturbance of the fiber balls during backwashing, resulting in complicated equipment structure, poor working reliability and high energy consumption. Automatic cyclone filter device that can realize backwashing without external power
