[0023] In the above structure, the cam 5, transmission wheel 7, driven wheel 8, and transmission belt 9 are arranged, so that during the operation of the device, the output shaft of the motor 4 is used to drive the cam 5 to rotate, so that the transmission rod 6 drives the transmission wheel 7 to rotate, and the driven wheel 8 drives the stirring rod 14 to rotate. At the same time, the adding tube 10 is used to weigh the water purification agent to ensure that the corresponding water level is purified by the water purification agent of equal proportion weight, thereby improving the user's addition accuracy of the agent, using the cam 5 to push the filter screen 11 to shake, and then using the stirring rod 14 to stir the wastewater, thereby improving the wastewater treatment effect of the device and the energy utilization rate.

[0031] In the above structure, the through-slot structure is set so that the cam 5 can drive the filter 11 to move along the inner wall of the through-slot during rotation, and then cooperate with the elasticity of the return spring 17 to make the filter 11 produce high-frequency vibration, thereby increasing the filtering effect of the filter 11 on wastewater.

[0032] In a preferred embodiment: the driven wheel 8 is connected to the driving wheel 7 through the transmission belt 9, the outer wall of the box body 1 is fixedly equipped with a positioning plate and a mounting plate, the outer wall of the positioning plate is rotatably connected to the outer wall of the driving wheel 7, and the outer wall of the mounting plate is rotatably connected to the outer wall of the cam 5.

[0035] In the above structure, by setting the inclined surface and the discharge port 12 structure, after the wastewater comes into contact with the reagent, the filter screen 11 is used to filter the condensed impurities and the original solid impurities in the wastewater, and the wastewater is discharged to the outside of the equipment through the inclined surface and the discharge port 12. After the filtering operation is completed, the user can also discharge the solid impurities to the outside of the box 1 by pulling the handle, so that the user can recover the wastewater and impurities.

[0036] Working principle, first after the device is assembled, the user can directly pour the wastewater into the box 1 through the adding pipe 24, and then the water level sensor 13 will display the water level on the control panel 2. After the wastewater is added, the output shaft of the motor 4 is used to drive the transmission rod 6 to rotate, so that the cam 5 pushes the filter 11 to shake, thereby filtering the wastewater. At the same time, the user can add purification agents to the adding pipe 10. As the agents continue to accumulate, the weighing plate 21 compresses the pressure spring 23, and the pressure sensor 3 weighs the weight of the agents. Then the solenoid valve 22 is automatically opened under the action of the controller, allowing the agents to fall into the box 1, so that the stirring rod 14 fully mixes the agents with the wastewater during the rotation process, thereby ensuring that the fine impurities in the wastewater are condensed, and then the condensed impurities and the original impurities in the wastewater are filtered through the filter 11. Finally, the user recovers the filtered wastewater from the discharge port 12, and then pulls the handle to discharge the impurities on the filter 11 to the outside of the box 1 through the discharge port 12.
