A liquid inlet and a backwash port are arranged at the top of the tank body, legs and a liquid discharge port are arranged at the bottom of the tank body, and two partition plates are arranged inside the tank body to divide the internal space of the tank body into three layers of space.

[0004] However, it still has the following drawbacks. During the backwashing process, stirring the fiber balls may not be able to effectively remove the stains adsorbed on the fiber balls.

[0005] Based on this, the utility model designs a fiber ball filter to solve the above problems. Summary of the Utility Model

[0006] Aiming at the above-mentioned disadvantages of the prior art, the utility model provides a fiber ball filter.

[0007] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0009] The backwash assembly includes a stirring device and a pressing device. The filter tank is connected to the stirring device and the pressing device, and the stirring device is connected to the pressing device;

[0010] A filter device that is convenient for the fiber balls to reset and is easy to move is installed on the filter tank;

[0011] An inlet and outlet device for materials and sewage to enter and exit is installed on the filter tank;

[0012] A support device for supporting and fixing is installed on the filter tank.

[0013] Furthermore, the stirring device includes a motor, a rotating shaft, stirring blades and a sliding groove. A motor is fixedly connected to the upper end of the filter tank. The output end of the motor passes through the filter tank and is fixedly connected to the rotating shaft.

A sliding groove is opened on the outer wall of the lower end of the rotating shaft, and the sliding groove is connected to the pressing device.

[0014] Furthermore, the rotating shaft is connected to the pressing device.

[0015] Furthermore, the pressing device includes a pressing plate, a sleeve, a slider and a limiting block. A pair of limiting blocks are fixedly connected to the inner wall of the filter tank. The pair of limiting blocks are slidably connected to the pressing plate. The outer wall of the rotating shaft is slidably connected to the sleeve. The slider is slidably connected in the chute. The inner wall of the sleeve is fixedly connected to the slider. The lower end of the sleeve is fixedly connected to the pressing plate.

[0016] Furthermore, a plurality of slots slightly smaller than the fiber balls are equidistantly arranged on the pressing plate.

[0017] Furthermore, the filter device facilitating movement includes a filter plate, a support block, a limiting column and a spring. A plurality of pairs of support blocks are equidistantly fixedly connected to the inner wall of the filter tank. A limiting column is fixedly connected to the opposite ends of a pair of support blocks. The filter plate is slidably connected to the outer wall of the limiting column.

[0020] The beneficial effects of the present utility model compared with the prior art are as follows:

[0021] 1. The present utility model is powered by the motor of the stirring device of the backwashing assembly. The output end of the motor drives the rotating shaft to rotate. The rotation of the rotating shaft drives the stirring blades to rotate and stir the liquid. At the same time, the rotation of the rotating shaft drives the chute to rotate. The rotation of the chute drives the slider of the pressing device to reciprocate up and down along the direction of the chute. The movement of the slider drives the sleeve and the pressing plate to move up and down along the rotating shaft to squeeze the fiber balls. The limiting block prevents the pressing plate from rotating. The stirring of the device drives the liquid to wash the fiber balls. At the same time, the extrusion of the pressing plate presses out the pollutants adsorbed inside the fiber balls, so as to achieve sufficient backwashing of the fiber balls.

[0022] 2. The filtering plate of the filter device which is easy to move is pressed to move downwards by the downward movement of the pressing plate, and the spring is compressed by the downward movement of the filtering plate. When the pressing plate moves upwards, the spring is no longer pressed. The spring pushes the filtering plate to move upwards. The function of the supporting block is to support the limiting column. Through the vibration generated by the up and down movement of the filtering plate, the fiber balls with uneven distribution after stirring are rearranged evenly on the filtering plate, avoiding the reduction of the filtering efficiency of the device caused by the uneven arrangement of the fiber balls.
