[0033] The specific configuration and function of the extrusion device 6 and the replacement device 7 will be described in detail below.

[0034] like Figure 1-Figure 5As shown, the extrusion device 6 includes a mounting plate 602, which is fixedly connected to the side of the filter tank 1, and a motor 601 is fixedly connected to the upper surface of the mounting plate 602. The output end of the motor 601 is fixedly connected to a threaded rod 604, and the threaded rod 604 is rotatably connected to the inner wall of the filter tank 1. The surface of the threaded rod 604 is covered with an extrusion plate 605. By setting the mounting plate 602, the motor 601 can be fixedly installed, and by setting the motor 601, the threaded rod 604 can be driven to rotate, thereby controlling the extrusion plate 605 to move inside the filter tank 1, squeezing the oily wastewater, and promoting the grease to enter the oil outlet pipe 51 through the oil-water separation net 52. The side of the mounting plate 602 is fixedly connected to a control board 603, and the control board 603 is electrically connected to the motor 601. The inner wall of the extrusion plate 605 is slidably connected to two slide plates 606, and the ends of the two slide plates 606 that are away from each other are both rotatably connected to a rotating plate 607. By setting the control board 603 , the motor 601 can be automatically controlled, and the slide plate 606 slidably connected to the inner wall of the extrusion plate 605 can drive the rotating plate 607 to move closer to or away from the extrusion plate 605 .

By setting the slide rod 610, the position of the spring 611 can be restricted, and by setting the spring 611, the movement of the slide plate 606 can be controlled.

[0036] like Figure 2 and Figure 6 as well as Figure 7 As shown, the replacement device 7 includes three sealing plates 73, and the three sealing plates 73 are all slidably connected to the inner wall of the filter tank 1. The surfaces of the three second filter discs 54 are all fixedly connected with three baffles 71, and the surfaces of the three second filter discs 54 are all fixedly connected with blocking rings 72. By setting the sealing plates 73, the filter tank 1 can be opened or closed, so that the activated carbon can be replaced conveniently. By setting the baffles 71, the activated carbon can be replaced conveniently in different areas. By setting the blocking rings 72, the position of the filter paper can be restricted when the filter paper on the surface of the second filter disc 54 is replaced.

[0037] The surfaces of the three sealing plates 73 are all fixedly connected with handles 74, and the surfaces of the three sealing plates 73 are all fixedly connected with limit plates 75. By providing the handles 74, the sealing plates 73 can be conveniently moved, and by providing the limit plates 75, the positions of the sealing plates 73 can be fixed. The surface of the filter tank 1 is fixedly connected with three fixing plates 76, and the inner walls of the three fixing plates 76 are all threadedly inserted with screws 77, and the screws 77 are threadedly inserted on the inner walls of the limit plates 75. By providing the fixing plates 76, the screws 77 can be installed on the filter tank 1, and by providing the screws 77, the fixing plates 76 and the limit plates 75 can be connected, so that the position of the limit plates 75 can be limited.

[0038] Working principle: When using the filtering device for treating oily wastewater to filter oily wastewater, firstly, the filter cloth is installed on the surface of the first filter disc 53 and the second filter disc 54, and then the cellulose and activated carbon are installed on the surface of the first filter disc 53 and the second filter disc 54 respectively. The oily wastewater is passed into the filter tank 1 through the water inlet pipe 2, and passes through the oil-water separation net 52 of the filter mechanism 5, so that the grease is discharged through the oil outlet pipe 51. After that, the sewage passes through the first filter disc 53 and the second filter disc 54, and then enters the treatment box 4 through the water outlet pipe 3 for further treatment. When performing oil-water separation, firstly, the motor 601 and the control board 603 are connected to the external power supply, and the motor 601 is controlled to rotate forward and reversely through the control board 603. The forward rotation of the motor 601 drives the threaded rod 604 to rotate forward, thereby controlling the squeezing plate 605 to move close to the oil outlet pipe 51. At the same time, during the movement of the squeezing plate 605, under the action of the elastic force of the spring 611 and the squeezing of the rotating plate 607 by the filter tank 1, the slide plate 606 slides on the surface of the slide bar 610, so that the slide plate 606 moves away from or approaches the squeezing plate 605, and the rotating plate 607 can maintain contact with the inner wall of the filter tank 1, thereby achieving a better squeezing effect on the sewage. During the movement of the squeezing plate 605 close to the oil outlet pipe 51, the rotating plate 607 is blocked. Under the action of rod 608, sewage can be prevented from pushing the rotating plate 607 to rotate. When the motor 601 reverses, the threaded rod 604 reverses, and the squeezing plate 605 moves away from the oil outlet pipe 51. The movement of the squeezing plate 605 allows the sewage to push the rotating plate 607 to rotate close to the baffle 609. At this time, the sewage can pass through the rotating plate 607 to approach the oil outlet pipe 51. By setting the mounting plate 602, the motor 601 and the control board 603 can be installed. By setting the squeezing device 6, the pressure on the sewage can be increased during the process of filtering the oily wastewater using the filtering device for treating oily wastewater, thereby maximizing the efficiency of grease passing through the oil-water separation net 52 and reducing the time required for oil-water separation as much as possible.

[0039] When it is necessary to replace the activated carbon, first stop passing the oily wastewater into the water inlet pipe 2, then rotate the screw 77 to make it rotate on the inner wall of the fixed plate 76, and the screw 77 moves away from the limit plate 75 to release the restriction on the position of the limit plate 75. Grasp the handle 74 to control the sealing plate 73 to slide on the inner wall of the filter tank 1, open the filter tank 1, take out the activated carbon and filter paper, first lay the new filter paper on the surface of the second filter disc 54, and then place the new activated carbon on the second filter disc 54, then move the limit plate 75 close to the fixed plate 76, and rotate the screw 77 to fix the position of the limit plate 75. By setting the baffle 71, it is convenient to replace the activated carbon in different areas, and by setting the blocking ring 72, it is convenient to place the filter paper. By setting the replacement device 7, it is convenient to replace the activated carbon, thereby ensuring the deodorization and decolorization effect of the wastewater as much as possible when treating the wastewater.
