[0014] The present invention provides a precise automatic dosing device for disinfectant, which has the following beneficial effects:

[0015] (1) This invention drives the reciprocating screw to rotate by the rotation of the motor, and drives the threaded block to reciprocate by the reciprocating motion of the reciprocating screw. When the threaded block moves upward, it pushes the threaded rod to move upward, causing the water inlet ring to move upward. The disinfectant enters the water treatment tank through the upward movement of the water inlet ring. By intermittently disinfecting the sewage, it can ensure that the disinfectant is fully mixed with the sewage, thereby improving the disinfection effect. At the same time, when the threaded rod moves upward, it drives the fan blades to rotate. The rotation of the fan blades is used to stir the disinfectant water, thereby preventing the disinfectant from stratifying or precipitating components, which may lead to a poor disinfection effect.

[0016] (2) This invention uses the reciprocating motion of the threaded block to drive the arc plate to scrape the inner wall of the treatment box. When the arc plate moves downward, it scrapes the inner wall to prevent impurities in the sewage from adhering to the inner wall of the treatment box and affecting subsequent sewage treatment. At the same time, when the threaded block moves downward, it contacts the inclined plate, which causes the arc plate to shrink. The arc plate will not contact the inner wall of the treatment box during its rising process, preventing the inner wall of the treatment box from being scraped for a long time, which would reduce the service life of the arc plate.

[0017] (3) This invention rotates the rotating plate to flip the sewage at the bottom upward, so that the sewage and disinfectant water are mixed more fully. At the same time, the threaded block moves downward to contact the push rod, and the push rod moves downward to drive the sealing block to move downward to open the drain port, thereby discharging the sewage inside and improving the efficiency of replacing sewage. At the same time, when the drain port is opened, the water inlet pipe will be closed to prevent the sewage from being discharged directly without being disinfected, which poses a safety hazard.

The disinfectant is stirred by the rotation of the fan blades 14 to prevent the disinfectant from stratification or precipitation of components, which may cause the disinfection effect to deteriorate.

[0028] A water inlet hole is provided on the surface of the water inlet ring 13 , a water inlet groove is provided on the inner wall of the threaded rod 11 , the connecting rod 8 is arranged at the bottom of the circular plate 12 , and disinfectant is arranged inside the disinfection box 9 .

[0029] When the present embodiment is working, sewage enters through the water inlet pipe 2, and the motor 4 rotates to drive the reciprocating screw rod 5 to rotate to stir the sewage inside. The reciprocating screw rod 5 rotates and drives the threaded block 7 to reciprocate. The reciprocating motion of the threaded block 7 drives the connecting rod 8 to reciprocate. When the connecting rod 8 moves upward, it contacts the circular plate 12. The connecting rod 8 pushes the circular plate 12 to move upward. The upward movement of the circular plate 12 drives the threaded rod 11 to move upward. The upward movement of the threaded rod 11 drives the water inlet ring 13 to move upward.

[0032] The arc plate 152 contacts the inner wall of the processing box 1 , a first torsion spring is arranged between the L-shaped rod 154 and the rotating rod 156 , and the first torsion spring drives the rotating rod 156 to return to its original position, and the inclined plate 157 contacts the inner wall of the processing box 1 .

[0033] A drainage device is provided at the bottom of the treatment box 1, which includes a bevel gear 161, a slave gear 162, a fixed plate 163, a rotating plate 164, a sealing block 166, a push rod 165 and an elastic telescopic connecting rod 167. The rotating plate 164 is rotated to make the sewage at the bottom flip upward, so that the sewage and the disinfectant water are mixed more fully. The bevel gear 161 is fixedly installed at the bottom of the reciprocating screw 5, the fixed plate 163 is fixedly installed at the bottom of the inner wall of the treatment box 1, the rotating plate 164 rotates and penetrates the surface of the fixed plate 163, the slave gear 162 is fixedly installed on the surface of the rotating plate 164, the bevel gear 161 is meshed with the surface of the slave gear 162, the elastic telescopic connecting rod 167 is fixedly installed at the bottom of the treatment box 1, the sealing block 166 is fixedly installed at the fixed end of the elastic telescopic connecting rod 167, the push rod 165 is fixedly installed on the top of the sealing block 166, and the sealing block 166 moves downward to open the drain port to discharge the internal sewage, thereby improving the efficiency of replacing sewage.

[0034] A water inlet 169 is slidably installed at the bottom of the inner wall of the water inlet pipe 2, a sealing plate 1610 is fixedly installed on the top of the water inlet 169, a connecting rope 168 is fixedly installed on the top of the elastic telescopic rod 151, and the connecting rope 168 is fixedly installed at the bottom of the water inlet 169 to prevent the water inlet pipe 2 from being in an open state continuously when discharging sewage, resulting in the sewage being directly discharged without being disinfected, posing a safety hazard.

[0035] The push rod 165 is arranged at the bottom of the threaded block 7, and a No. 1 spring is arranged between the water inlet pipe 2 and the water inlet 169, and the water inlet 169 is driven to reset by the No. 1 spring.

[0036] When the embodiment is working, the reciprocating motion of the threaded block 7 drives the elastic telescopic rod 151 to reciprocate, and the elastic telescopic rod 151 reciprocates. When the threaded block 7 drives the elastic telescopic rod 151 to move downward, the downward movement of the elastic telescopic rod 151 will drive the arc plate 152 to move downward, and the downward movement of the arc plate 152 will drive the spring piece 153 to move downward. The inner wall of the treatment box 1 will be scraped by the arc plate 152 and the spring piece 153 to prevent impurities in the sewage from adhering to the inner wall of the treatment box 1 and affecting the subsequent sewage treatment. At the same time, when the arc plate 152 moves downward, it will contact the inclined plate 157, and the arc plate 15 2 will push the inclined plate 157 to rotate downward. When the arc plate 152 is separated from the inclined plate 157, the No. 1 torsion spring will drive the inclined plate 157 to reset. The inclined plate 157 will rest against the inner wall of the processing box 1. At the same time, when the arc plate 152 moves upward, it will contact the inclined plate 157. Through the inclined surface of the inclined plate 157, when the arc plate 152 contacts the inclined surface, a manual reverse force will be applied to move the arc plate 152 away from the inner wall of the processing box 1, so that the arc plate 152 moves away from the inner wall of the processing box 1 during the rising process, preventing the arc plate 152 from continuously scraping the inner wall when moving upward, which will reduce the service life of the arc plate 152 and increase the cost.

At the same time, when the drain port is opened, the elastic telescopic rod 151 moves downward to drive the connecting rope 168 to move downward, and the connecting rope 168 moves to The downward movement will drive the water inlet 169 to move downward, and the downward movement of the water inlet 169 will drive the sealing plate 1610. The downward movement of the sealing plate 1610 will block the bottom of the water inlet pipe 2 to prevent the water inlet pipe 2 from being in an open state continuously when discharging sewage, resulting in the sewage being discharged directly without being disinfected, which poses a safety hazard. At the same time, when the sewage is discharged, the rotation of the reciprocating screw 5 will drive the threaded block 7 to rise, and the rising of the threaded block 7 will be separated from the squeezing of the sealing block 166, so that the elastic force of the elastic telescopic connecting rod 167 itself drives the sealing block 166 to reset, and the drain outlet is blocked by the sealing block 166. When the drain outlet is blocked, the water inlet will be opened, allowing the sewage to enter the interior of the treatment box 1, disinfect the sewage, and improve the disinfection efficiency.
