[0030] It also includes a reciprocating screw slider 4 and a cleaning brush 5: the reciprocating screw slider 4 is installed on the reciprocating screw 3, the cleaning brush 5 is fixedly connected to the bottom outer wall of the reciprocating screw slider 4, and the bristles at the bottom of the cleaning brush 5 are in contact with the top of the filter screen 2;

[0031] Furthermore, two guide transverse shafts 11 are symmetrically fixed to the upper inner wall of the sewage purification box 1, and two guide sleeves 12 are symmetrically fixed to the top outer wall of the cleaning brush 5, and the two guide sleeves 12 are slidably connected to the two guide transverse shafts 11 respectively;

[0032] Furthermore, both sides of the sewage purification box 1 are provided with impurity removal oblique openings 23 adapted to the position of the filter screen 2, and both sides of the sewage purification box 1 are plugged with impurity collection boxes 22. The plug-in effect of the impurity collection box 22 is achieved by welding plug blocks on the side walls of the impurity collection box 22 and opening slots on the side walls of the sewage purification box 1, thereby facilitating the disassembly and assembly of the impurity collection box 22;

[0033] When the online cleaning mechanism of this embodiment is in use, the cleaning brush 5 installed at the bottom of the reciprocating screw slider 4 is driven by the driving mechanism to reciprocate on the surface of the filter screen 2, so that the impurities attached to the surface of the filter screen 2 can be effectively cleaned without stopping the machine for cleaning, and the sewage purification work will not be delayed;

[0034] In this embodiment, the deodorizing mechanism includes a fixed cover 6 and an air induced hood 7: the fixed cover 6 is fixedly connected to the outer wall of one side of the sewage purification box 1, a wind hole is opened on one side of the fixed cover 6, a protective net is fixedly connected to the side wall of the fixed cover 6, the air induced hood 7 is fixedly connected to the top of the sewage purification box 1, and the air induced hood 7 is connected to the fixed cover 6 through an air duct;

[0035] It also includes an activated carbon filter element 8: the activated carbon filter element 8 is fixedly connected to the air induced hood 7 and is located above the air hole;

[0036] It also includes a transmission shaft 9 and an induced draft fan blade 10: the transmission shaft 9 is coaxially welded to the outer wall of one end of the reciprocating screw rod 3, and the induced draft fan blade 10 is fixedly sleeved on the transmission shaft 9, and the induced draft fan blade 10 is located in the air hole;

[0037] When the deodorizing mechanism in this embodiment is in use, through the cooperation of the induced draft fan blades 10, the induced draft cover 7 and the activated carbon filter element 8, some odors emitted from the sewage can be eliminated to a certain extent during the sewage purification process, thereby reducing the pollution caused by the odor to the surrounding environment;

[0038] In this embodiment, the liquid medicine stirring mechanism is arranged below the filter screen 2, and the liquid medicine stirring mechanism includes a stirring shaft 13 connected to the lower inner wall of one side of the sewage purification tank 1 through a sealed bearing and a stirrer 14 fixedly connected to the stirring shaft 13, so that the liquid medicine and the sewage can be fully mixed, thereby improving the sewage treatment effect;

[0039] In this embodiment, the driving mechanism includes a motor bracket 15 welded to the lower outer wall of the other side of the sewage purification tank 1, a driving motor 16 fixedly mounted on the side wall of the motor bracket 15, a first pulley 17 fixedly mounted on the stirring shaft 13, and a second pulley 18 fixedly mounted on the reciprocating screw 3;

Through the driving effect of the driving mechanism, the online cleaning mechanism, the liquid medicine stirring mechanism and the deodorization mechanism share a driving source, which is more convenient to operate and can effectively reduce the cost of use.

[0041] The working principle of this embodiment is as follows: first, the sewage will enter the sewage purification box 1 from the liquid inlet pipe 19, and the sewage entering will be fully filtered by the filter 2, and then the filtered sewage will react with the agent added from the dosing pipe 20 below to complete the sewage purification effect, and the purified sewage will be discharged from the drain pipe 21;

[0042] Secondly, the stirring shaft 13 is controlled to rotate by driving the motor 16. At this time, the stirrer 14 on the stirring shaft 13 rotates to fully mix the medicine and the sewage, and the No. 1 pulley 17 on the stirring shaft 13 also rotates. Under the transmission effect of the belt, the No. 2 pulley 18 drives the reciprocating screw 3 to rotate, and then the cleaning brush 5 installed at the bottom of the reciprocating screw slider 4 reciprocates on the surface of the filter 2, so that the impurities attached to the surface of the filter 2 can be effectively cleaned without stopping the machine for cleaning, and the sewage purification work will not be delayed;

[0043] Finally, the cleaned impurities will be discharged from the impurity removal inclined ports 23 on both sides into the two impurity collection boxes 22 for unified collection, and the rotation of the reciprocating screw 3 will drive the induced draft fan blades 10 on the transmission shaft 9 to rotate, and then the odor in the sewage purification box 1 will be introduced into the fixed cover 6 through the induced draft hood 7. At this time, the odor is purified under the adsorption purification of the activated carbon filter element 8. In this way, some odors emitted from the sewage can be eliminated to a certain extent during the sewage purification process, thereby reducing the pollution caused by the odor to the surrounding environment.
