The liquid discharge bin 6 is semispherical to avoid liquid retention in the interior of the liquid discharge bin 6. The screen 7 is fixedly embedded in the joint between the liquid discharge bin 6 and the filter jar 1.

[0029] A brush 8 is attached to the top of the screen 7 at the bottom end of the main shaft 3. A liquid discharge pipeline is embedded in the bottom of the liquid discharge bin 6. A valve is arranged on the liquid discharge pipeline to control the opening and closing of the liquid discharge pipeline. An inlet 9 extending into the inner chamber of the filter bin 2 is embedded in the sidewall of the filter jar 1. The inlet 9 is fixedly embedded in the sidewall of the filter jar 1, and the inlet 9 penetrates the sidewall of the filter bin 2 and extends into the inner chamber. The inlet 9 is connected to the wastewater inlet pipeline through the flange, so that the wastewater enters the filter bin 2 in the inner chamber of the filter jar 1 through the inlet 9. The brush 8 is fixedly installed on the top of the brush 8 at the bottom end of the main shaft 3, so that the brush 8 rotates with the main shaft 3 and is attached to the top of the screen 7.

[0030] In the process of separating and filtering solid and liquid, the main shaft 3 drives the filter 4 and the brush 8 to rotate at the same time. The wastewater is introduced into the inner cavity of the filter tank 1 through the input port 9 and enters the inside of the filter bin 2, so that the wastewater falls on the rotating filter 4, and the solid in the wastewater is preliminarily screened through the filter hole 12 on the filter 4. Then the liquid passes through the filter hole 12 and falls on the screen 7 from the discharge port 5 at the bottom of the filter bin 2, and the wastewater is filtered twice through the screen 7, thereby improving the filtering effect of the wastewater. The twice-screened solid is left on the surface of the screen 7, and the screen hole on the screen 7 is cleaned by the continuously rotating brush 8, avoiding the blockage of the screen hole, thereby ensuring the smoothness of the solid separation and filtration process and the efficiency of the solid-liquid separation and filtration process.

[0031] The bottom of the filter bin 2 is fixedly installed with an annular stepped holder 23, an annular support 11 is rotatably arranged between the filter bin 2 and the annular stepped holder 23 and abuts against the inner wall of the filter tank 1, and the annular support 11 is fixedly connected with the brush 8 through the reinforcing rods 20.

The upper step part of the annular stepped holder 23 is fixedly installed at the bottom of the filter bin 2, and the lower step part of the annular stepped holder 23 forms a circumferential cavity with the filter bin 2, so that the annular support 11 rotates on the inner wall of the circumferential cavity between the annular stepped holder 23 and the filter bin 2.

[0032] In the process of rotating the brush 8 with the main shaft 3, the brush 8 drives the annular support 11 to rotate on the inner wall of the filter tank 1 through the two reinforcing rods 20 at the same time, and the annular support 11 rotates between the annular stepped holder 23 and the bottom of the filter bin 2, thereby ensuring the stability of the rotation of the brush 8, avoiding the position deviation of the brush 8, and thereby ensuring the cleaning effect of the screen hole on the screen 7 and improving the flowability of the liquid.

[0033] The bottom of the filter bin 2 is symmetrically provided with the discharge port 5, the discharge port 5 is located on one side of the main shaft 3, and the discharge port 5 corresponds to the central through holes of the annular support 11 and the annular stepped holder 23.

[0035] In the process of rotating the filter hopper 4 and the brush 8 by the main shaft 3, the main shaft 3 simultaneously drives the deviation preventing seat 15 to rotate, so that the deviation preventing seat 15 drives the rolling balls 16 to slide along the inner wall of the sliding groove 22 through the plurality of movable grooves 17 in the circumferential direction, thereby ensuring the stability of the main shaft 3 during rotation.

[0036] The sidewall of the filter tank 1 is embedded with a solid material taking port 10, and the solid material taking port 10 is located between the filter bin 2 and the screen 7.

[0038] In the process of rotating the main shaft 3, the main shaft 3 simultaneously drives the scraper 19 to slide along the inner wall of the filter bin 2 through the connecting rod 18, thereby allowing the dirt and debris on the inner wall of the filter bin 2 to fall off, thereby achieving a protective effect on the filter bin 2.

[0039] In addition, the top and bottom of the filter tank 1 are detachable from the tank body. The top and bottom of the filter tank 1 are both semispherical structures, and are connected by a fixing piece. The top and bottom can be removed through the fixing piece, making maintenance more convenient.

[0040] Further, the bottom of the filter tank 1 is embedded with a liquid discharge channel, and a valve is arranged on the liquid discharge channel. The opening and closing of the liquid discharge channel are controlled by the valve, making the operation of the liquid discharge process more convenient.

[0041] The working principle of the full-automatic brush type self-cleaning filter is as follows: firstly, the motor 14 is connected to the power supply, so that the output shaft of the motor 14 drives the main shaft 3 to rotate, and the main shaft 3 simultaneously drives the filter hopper 4 and the brush 8 to rotate. Then, the input port 9 is connected to the wastewater access pipeline through the flange, so that the wastewater enters the filter tank 1 into the filter bin 2 in the inner cavity.

[0042] The wastewater is introduced into the inner cavity of the filter tank 1 through the input port 9 and enters the inside of the filter bin 2, so that the wastewater falls on the rotating filter hopper 4, and the solids in the wastewater are preliminarily screened through the filter holes 12 on the filter hopper 4, and then the liquid falls on the screen 7 from the discharge port 5 at the bottom of the filter bin 2 after passing through the filter holes 12, and the wastewater is secondarily filtered through the screen 7.

[0043] Then, the liquid is discharged through the liquid discharge channel at the bottom, and the solids are taken out through the solid taking-out port 10 on the side wall.
