[0030] A filter plate 6 is fixedly installed at two-thirds of the inner wall of the treatment box 1, and the filter plate 6 is arranged below the water inlet 2. A partition plate 5 is fixedly installed on the side of the upper surface of the filter plate 6 away from the water inlet 2. Wastewater is poured into the treatment box 1 from the water inlet 2, and large solid particles are filtered out of the wastewater through the filter plate 6. The wastewater with large solid particles filtered out flows into the treatment box 1 outside the partition plate 5 through the filter plate 6.

[0031] A driving device is provided on the bottom side of the inner wall of the processing box 1;

[0032] The driving device includes a motor 12, which is fixedly mounted on the bottom side of the inner wall of the processing box 1, and a first gear 11 is fixedly mounted on the output shaft of the motor 12;

[0033] Specifically, the output shaft of the motor 12 is fixedly connected to the eccentric position of the first gear 11, and the output shaft of the motor 12 drives the first gear 11 to rotate around the axis of the motor output shaft when rotating.

[0034] A groove slideway 16 is provided on the inner wall of the processing box 1 at a position corresponding to the motor 12, and a slider 8 is slidably installed inside the groove slideway 16;

[0035] Specifically, a spring 17 is fixedly installed on a side of the groove slideway 16 away from the slider 8 , and one end of the spring 17 away from the groove slideway 16 is fixedly connected to the slider 8 .

[0036] Furthermore, a rotating shaft 19 is fixedly installed on the bottom side of the slider 8, and a second gear 15 is rotatably installed on one end of the rotating shaft 19 away from the slider 8, and the second gear 15 is meshed and connected with the first gear 11; a stirring mechanism is provided on the side of the second gear 15 away from the rotating shaft 19;

[0037] Specifically, the stirring mechanism includes a shaft 13, which is fixedly mounted on the center position of a side of the second gear 15 away from the rotating shaft 19. A stirring blade 14 is fixedly connected to the outer arc surface of the shaft 13. The motor 12 is started, and the motor 12 rotates to drive the first gear 11 fixedly connected to the motor output shaft to rotate. The rotation of the first gear 11 drives the second gear 15 meshing with it to rotate around the rotating shaft 19. The rotation of the second gear 15 drives the shaft 13 to rotate. The rotation of the shaft 13 drives the stirring blade 14 fixed on the shaft 13 to rotate. The stirring blade 14 rotates to stir the wastewater and the agent in the treatment box 1, so that the wastewater and the agent are fully reacted.

[0038] A reverse bending rod 7 is fixedly mounted on the upper side of the slide block 8;

[0039] One end of the reverse bending rod 7 away from the slider 8 slides through the partition 5 , and a push plate 18 is fixedly mounted on the other end of the reverse bending rod 7 away from the slider 8 .

[0040] It should be noted that the reverse bending rod 7 includes an L-shaped connecting rod and a round rod fixedly connected to the L-shaped connecting rod. The L-shaped connecting rod is fixedly installed on the upper side of the slider 8, and one end of the round rod away from the L-shaped connecting rod is fixedly connected to the push plate 18.

[0041] It should be noted that the push plate 18 is located between the partition plate 5 and the inner wall of the treatment box 1 and is placed above the filter plate 6, and the bottom of the push plate 18 is in contact with the filter plate 6. The eccentric position of the first gear 11 in which the second gear 15 is meshed is fixedly connected to the motor output shaft, so that the first gear 11 can not only rotate the second gear 15 during rotation, but also displace the second gear 15 in the horizontal direction. The second gear 15 is rotatably connected to the rotating shaft 19;

[0042] By setting the spring 17, when the first gear 11 rotates to the right, the first gear 11 pushes the second gear 15, the rotating shaft 19 and the slider 8 to move to the right, and the spring 17 contracts. When the first gear 11 rotates to the left, the spring 17 resets and pushes the slider 8 to move to the left synchronously with the rotating shaft 19 and the second gear 15, so that the second gear 15 always keeps meshing with the first gear 11, so that the slider 8 fixedly connected to the rotating shaft 19 can slide left and right along the groove slideway 16;

[0043] The left and right movement of the slider 8 can drive the reverse bending rod 7 fixed thereto to move left and right, and the reverse bending rod 7 drives the push plate 18 to slide along the filter plate 6 through the through hole on the partition plate 5, thereby pushing the large particles remaining on the upper end of the filter plate 6 to the edge of the filter plate 6, which is conducive to the filtered wastewater flowing through the filter plate 6 to the bottom of the treatment box 1 to react with the reagent. The wastewater that has fully reacted with the reagent is discharged through the water outlet 10.

[0044] Furthermore, a medicine box 3 is fixedly installed on the inner wall of the treatment box 1 at a position above the motor 12. The interior of the medicine box 3 is hollow, a medicine inlet pipe 4 is fixedly installed on the upper end surface of the medicine box 3, and a plurality of medicine outlet pipes 9 are fixedly installed on the lower surface of the medicine box 3. The medicine is injected into the medicine box 3 from the medicine inlet pipe 4, and the medicine in the medicine box 3 flows into the treatment box 1 through the medicine outlet pipe 9 to react with the filtered wastewater.

[0045] Working principle: When in use, wastewater is poured into the treatment box 1 from the water inlet 2, and large solid particles are filtered out of the wastewater through the filter plate 6. The wastewater with large solid particles filtered out flows into the treatment box outside the partition 5 through the filter plate 6. At this time, the medicine is injected into the medicine box 3 from the medicine inlet pipe 4, and the medicine in the medicine box 3 flows into the treatment box 1 through the medicine outlet pipe 9 to contact and react with the filtered wastewater. At the same time, the motor 12 is started, and the motor 12 rotates to drive the first gear 11 fixedly connected to the motor output shaft to rotate. The rotation of the first gear 11 drives the second gear 15 meshing with it to rotate around the rotating shaft 19. The rotation of the second gear 15 drives the shaft 13 to rotate. The rotation of the shaft 13 drives the stirring blade 14 fixed on the shaft 13 to rotate. The stirring blade 14 rotates to stir the wastewater and the medicine in the treatment box 1, so that the wastewater and the medicine are fully reacted.

[0046] Because the first gear 11 meshing with the second gear 15 is fixedly connected to the motor output shaft at an eccentric position, the rotation of the first gear 11 can not only rotate the second gear 15, but also displace the second gear 15 in the horizontal direction. The second gear 15 is rotatably connected to the rotating shaft 19.

[0047] By setting the spring 17, when the first gear 11 rotates to the right, the first gear 11 pushes the second gear 15, the rotating shaft 19 and the slider 8 to move to the right, and the spring 17 contracts. When the first gear 11 rotates to the left, the spring 17 resets and pushes the slider 8, the rotating shaft 19 and the second gear 15 to move to the left synchronously, so that the second gear 15 and the first gear 11 always remain in meshing.

[0048] Therefore, the slider 8 fixedly connected to the rotating shaft 19 can slide left and right along the groove slideway 16. The left and right movement of the slider 8 can drive the reverse bending rod 7 fixed thereto to move left and right. The reverse bending rod 7 drives the push plate 18 to slide along the filter plate 6 through the through hole on the partition plate 5, thereby pushing the large particles remaining on the upper end of the filter plate 6 to the edge of the filter plate 6, which is conducive to the filtered wastewater flowing through the filter plate 6 to the bottom of the treatment box 1 to react with the reagent. The wastewater that has fully reacted with the reagent is discharged through the water outlet 10.

[0049] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
