DETAILED DESCRIPTION

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-4 As shown, the utility model provides a technical solution: an oily wastewater treatment device, including a support frame 1, a treatment tank 2 is connected inside the support frame 1, a feed pipe 3 is connected to the treatment tank 2, a discharge pipe 4 is connected below the treatment tank 2, a mounting plate 8 is clamped inside the treatment tank 2, a filter plate 9 is arranged inside the mounting plate 8, a limit plate 10 is connected outside the filter plate 9, an auxiliary block 13 is connected inside the mounting plate 8, a limit groove 14 is provided inside the mounting plate 8, the filter plate 9 is overlapped on the auxiliary block 13, and the limit plate 10 is clamped in the limit groove 14;

[0020] By providing the auxiliary block 13 and the limiting groove 14, when the filter plate 9 is connected to the mounting plate 8, the filter plate 9 will overlap on the auxiliary block 13, and the limiting plate 10 on the surface of the filter plate 9 will be clamped in the limiting groove 14, so that the auxiliary block 13 and the limiting groove 14 play a certain limiting role for the filter plate 9, avoiding the collision between the filter plate 9 and the mounting plate 8 during assembly;

[0021] The front of the support frame 1 is connected to a motor 5, and the front of the motor 5 is rotatably connected to a rotating plate 6, and one side of the rotating plate 6 is connected to a sealing plate 7, and the sealing plate 7 is overlapped under the discharge pipe 4. By setting the rotating plate 6 and the sealing plate 7, when the motor 5 drives the rotating plate 6 to rotate, the sealing plate 7 will rotate with the rotating plate 6, and the rotating plate 6 will be separated from the discharge pipe 4, so that the rotating plate 6 and the sealing plate 7 play a certain sealing role for the discharge pipe 4, avoiding leakage at the discharge port of the discharge pipe 4;

[0022] A fixed block 11 is connected to the outside of the treatment tank 2, and a moving plate 15 is slidably connected to the inside of the fixed block 11.

A cam 18 is rotatably connected to the outside of the fixed rod 17. A support block 19 is connected to the outside of the positioning plate 12. A spring 16 is provided under the moving plate 15. By providing the spring 16, when the positioning plate 12 is affected by thrust or tension, the positioning plate 12 will drive the spring 16 to deform, so that the spring 16 plays a certain supporting role in the movement of the positioning plate 12. When the positioning plate 12 loses resistance, it will be reset by the spring 16;

[0023] The movable plate 15 is connected to the fixed block 11 through a spring 16, a guide groove 20 is provided in the positioning plate 12, the fixed rod 17 is clamped in the guide groove 20, and the cam 18 overlaps the support block 19. By setting the guide groove 20, when the cam 18 rotates, the convex surface of the cam 18 contacts the support block 19, and the fixed rod 17 slides in the guide groove 20, so that the guide groove 20 plays a certain auxiliary role for the fixed rod 17, thereby preventing the positioning plate 12 from getting stuck with the fixed rod 17 when moving.
