[0045] Please refer to Figures 1 to 4 A wastewater treatment device, comprising:

[0046] Wastewater treatment tank 1, with a first inlet pipe 11 at the top, a drain pipe 12 on the bottom side wall, and a slag discharge port 13 on the side wall, the slag discharge port 13 being located above the drain pipe 12.

[0047] The stirring mechanism 2 is located on the wastewater treatment tank 1. The stirring mechanism 2 includes two stirring shafts 21 rotating in opposite directions, and several stirring rods 211 are provided on the stirring shafts 21.

[0048] Drive device 3, which is used to drive the two stirring shafts 21 to rotate;

[0049] The first sterilization tube is connected to the waste discharge box. The first sterilization tube is located above the stirring rod 211 and is parallel to the stirring shaft 21. The first sterilization tube is equipped with several spray nozzles 41.

[0050] Partition 5 is connected to the wastewater treatment tank 1. Partition 5 is located below the stirring shaft 21. A second water inlet pipe 51 is provided on partition 5.

[0051] Sterilization chamber 6 is connected to the top of wastewater treatment tank 1. Sterilization chamber 6 is equipped with a second sterilization pipe 61, which is connected to the first sterilization pipe 4. A liquid pump 611 is installed on the second sterilization pipe 61.

[0052] The filter screen is inclinedly connected inside the wastewater treatment tank 1. The high end of the filter screen is located below the second water inlet pipe 51, and the low end of the filter screen is connected to the sludge discharge port 13.

[0053] The squeezing box 7 is connected to the sterilization box 6 through the slag discharge port 13. The squeezing box 7 is equipped with a filter plate 71 with filter holes. The squeezing box 7 is equipped with a water outlet 72, which is connected to the wastewater treatment box 1. The water outlet 72 is located below the filter plate 71.

[0054] The extrusion plate 74 is located above the filter plate 71 and is movably connected to the extrusion box 7 in the vertical direction.

[0055] Drive component 8, which is used to drive the extrusion plate 74 to move;

[0056] Lead screw 9 is connected inside the wastewater treatment tank 1. Lead screw 9 is located below the filter screen, and the axis of lead screw 9 is parallel to the filter screen.

[0057] The movable seat 10 is slidably connected to the lead screw shaft 9. The movable seat 10 is provided with a rotatable roller brush 101, and the bristles of the roller brush 101 abut against the bottom of the filter.

[0058] The first drive motor 111 is connected to the lead screw shaft 9 for transmission.

[0059] Transmission device 121, the first drive motor 111 drives the roller brush 101 to rotate through transmission device 121;

[0060] Activated carbon layer 131 is connected inside wastewater treatment tank 1 and is located below lead screw shaft 9.

[0061] In the above embodiment, the wastewater enters through the first inlet pipe 11, is hydraulically opened, and the sterilization tank 6 sprays the chemical solution into the wastewater through the first sterilization pipe 4 and the second sterilization pipe 61, and then sprays it into the wastewater through the spray nozzle 41. Next, the drive device 3 drives the two stirring shafts 21 to rotate in opposite directions, mixing the chemical solution with the wastewater for preliminary sterilization. After sterilization, the wastewater falls through the second inlet pipe 51 onto the filter screen, where impurities remain. The wastewater continues to fall onto the filter screen, and the tilting of the filter screen and the pushing force of the wastewater cause the impurities to fall through the slag discharge port 13 onto the filter plate 71. Then, the drive component 8 drives the pressure plate to move, squeezing the impurities on the filter plate 71. The squeezed water flows out through the filter plate. The filter screen drops down and then enters the wastewater treatment tank 1 through the outlet 72. Finally, the garbage wastewater passing through the outlet 72 and the filter screen passes through the activated carbon layer 13, which can adsorb suspended impurities and odors in the wastewater. After the garbage wastewater is discharged from the drain pipe 12, the first drive motor 111 drives the lead screw shaft 9 to rotate, thereby moving the moving seat 10. Through the transmission device 12, the roller brush 101 rotates, and the bristles of the roller brush 101 brush the filter screen, thereby avoiding filter screen clogging. There is no need to disassemble the filter screen for cleaning. Compared with the existing technology, it can not only sterilize garbage wastewater and adsorb suspended impurities and odors in garbage and wastewater, but also clean impurities on the filter screen in a timely manner and prevent filter screen clogging without stopping the equipment.

[0063] In the above embodiments, the second drive motor 31 is turned on, and the first gear 32 and the second gear 33 mesh, so that the two stirring shafts 21 rotate in opposite directions, thereby enabling the liquid medicine to be better mixed with the garbage wastewater, achieving the effect of preliminary sterilization.

[0064] As an optional implementation, the transmission device 121 includes a third gear 1211 and a rack 1212. The rack 1212 is connected inside the wastewater treatment tank 1 and is parallel to the axial direction of the lead screw shaft 9. The third gear 1211 is coaxially connected to the output shaft of the brush roller and meshes with the rack 1212.

[0065] In the above embodiments, by using the first drive motor 111 to start, the lead screw shaft 9 is driven, which in turn causes the moving seat 10 to move. During the movement of the moving seat 10, the third gear 1211 meshes with the rack 1212, which in turn enables the roller brush 101 to rotate, allowing the bristles of the roller brush 101 to brush the filter screen and prevent the filter screen from clogging.
