The micro-vibration motor 19 is a micro-motor with a set of adjustable eccentric blocks installed at both ends of the rotor shaft, and the centrifugal force generated by the high-speed rotation of the shaft and the eccentric blocks is used to obtain the exciting force. The model of the micro-vibration motor 19 is MVE20, and a connecting frame 15 is fixedly connected to the bottom surface of the filter cartridge 8. The outer surface of the connecting frame 15 is connected to the The inner walls of the feed hopper 3 are in contact with each other, and the inner walls of the connecting frame 15 are fixedly connected with the lower filter screen 16 and the support frame 23 respectively.

The bottom surface of each rotating blade 21 is in contact with the upper surface of the upper filter screen 17, and the upper surface of each rotating blade 21 is fixedly connected with a permanent magnet 22.

[0024] A micro vibration motor 19 fixed to the bottom surface of the upper filter 17 is used to generate vibrations to accelerate the filtering speed of the sewage on the upper filter 17, and the vibrations can also be used to allow debris in the filter mesh of the upper filter 17 to pass through the upper filter 17 and enter the lower filter 16 for filtration. A rotating fan blade 21 is provided on the upper filter 17, and a permanent magnet 22 is provided on the rotating fan blade 21. The rotating fan blade 21 driven by the rotating motor 18 can be used to stir the sewage on the upper filter 17, thereby reducing the clogging of the filter mesh of the upper filter 17. The permanent magnet 22 is used to adsorb metal particles in the sewage, thereby improving the treatment effect of the sewage treatment device.

[0025] Furthermore, the bottom surface of the feed hopper 3 is fixedly connected to a primary treatment cylinder 2, and the bottom surface of the primary treatment cylinder 2 is fixedly connected to a lower bottom plate 1.

[0032] Working principle: When in use, first connect the water pump 12, the rotating motor 18 and the micro-vibration motor 19 to the power supply. When the sewage treatment device needs to be used to treat the sewage generated during the construction process of the construction project, first manually twist the connecting nut 20 threaded at the output end of the rotating motor 18 to install the rotating fan blade 21 and the permanent magnet 22 on the upper filter screen 17, and manually twist and tighten the bolt 11 to make the connecting nut 20 tightly connected to the output end of the rotating motor 18, then manually install the filter cartridge 8 into the inside of the feed hopper 3, and use the limit block 7 to clamp into the limit groove 14 provided on the limit ring 6, so that the filter cartridge 8 and the lower filter screen 16 can be firmly installed into the inside of the feed hopper 3, and then manually place the sewage treatment device on the horizontal ground, so that the lower base plate 1 can be stably placed in the required position, so that the sewage treatment device can be stably used to treat the sewage generated during the construction process of the construction project;

[0033] Then, the sewage is transported to the inside of the feed hopper 3 through the pipeline, and the upper filter screen 17 and the lower filter screen 16 can be used to perform secondary filtration on the sewage in turn and transport it to the primary treatment cylinder 2. By controlling the power supply of the water pump 12, the filtered sewage can be transported to the secondary treatment cylinder 9 through the output pipe 13 using the power provided by the water pump 12, and the sewage treatment agent is added into the secondary treatment cylinder 9 through the pipeline on the secondary treatment cylinder 9, so that the treated sewage is discharged through the drainage pipe connected to the outer surface of the secondary treatment cylinder 9. When the sewage is filtered in turn by the upper filter screen 17 and the lower filter screen 16, by controlling the power supply of the rotating motor 18 and the micro vibration motor 19, The sewage filtered on the upper filter 17 is vibrated by the vibration generated by the micro-vibration motor 19 fixed under the upper filter 17, so that the debris stuck in the mesh of the upper filter 17 can pass through and be filtered by the lower filter 16, thereby accelerating the filtering speed of the sewage. The connecting nut 20 and the rotating fan blade 21 are driven to rotate by the rotating motor 18, and the rotating fan blade 21 can be used to stir the sewage and debris on the upper filter 17. The permanent magnet 22 on the rotating fan blade 21 is used to adsorb the metal particles in the debris, so as to reduce the clogging of the mesh of the upper filter 17 by the debris. The above steps can be repeated to clean the debris filtered on the lower filter 16 and the upper filter 17.
