[0058] Embodiment 1: Figure 1-Figure 8As shown, a purification component 7 is provided, and sewage to be treated is input through the water inlet pipe 4, and the reciprocating motor 73 is started to reciprocate, and the reciprocating motor 73 drives the screw rod 74 to rotate, and the screw rod 74 drives the stirring rod 75 to rotate, so that the sewage contacts and purifies with the treatment agent through the filter hole 89, and the screw rod 74 drives the bottom rod 77 to rotate, and the bottom rod 77 drives the mounting column 712 and the rotating disk 711 to rotate, and the rotating disk 711 drives the shifting tooth 714 to rotate. When rotating forward, the shifting tooth 714 is squeezed and rebounded by the inner teeth of the inner gear ring 717. At this time, the inner gear ring 717 and the upper turntable 715 do not rotate, and the rotating groove 716 corresponds to the position of the circulation groove 710, so that the sewage flows into the filter screen plate 76 after treatment. The filter screen plate 76 can select activated carbon. After being treated by the filter screen plate 76, the sewage flows into the lower part of the discharge barrel 6 and is discharged from the drain pipe 5.

[0059] During reversal, the shifting tooth 714 is stuck on the inner teeth of the inner gear ring 717, so that the shifting tooth 714 drives the inner gear ring 717 to rotate together, and the inner gear ring 717 drives the upper turntable 715 to rotate, so that the rotating groove 716 is separated from the circulation groove 710. At this time, the sewage is blocked by the baffle 79 for a period of time, so that the sewage and the treatment agent are in full contact. The intermittent water drop setting increases the contact time between the sewage and the treatment agent, thereby improving the sewage treatment and purification effect, and the discharge barrel 6 can be removed separately, which is convenient for replacing the internal treatment agent, improving the convenience of use, and solving the problem that some wastewater does not react completely with the treatment agent and flows down after being treated by the activated carbon plate, reducing the reaction time and reaction effect of the wastewater and the treatment agent, thereby reducing the quality of wastewater treatment.

[0060] The internal threads of the two adjustment sleeves 81 are in opposite directions. The adjustment sleeves 81 are threadedly connected to the screw rod 74. A sliding rod 85 is fixedly connected to one side of the arc plate 83 close to the fixed cylinder 84. A spring 86 is fixedly installed inside the fixed cylinder 84. The sliding rod 85 is slidably connected to the fixed cylinder 84.

[0061] One end of the slide bar 85 away from the arc plate 83 is fixedly connected to the spring 86. There are no less than two fixed tubes 84. The number of the slide bars 85 is the same as that of the fixed tubes 84, and the positions correspond one to one.

[0062] The inside of the discharge barrel 6 is symmetrically provided with slide grooves 87, and the side plate 82 is slidably connected to the slide grooves 87. The outside of the discharge barrel 6 is symmetrically provided with filter holes 89. A push rod 88 is fixedly connected to the side of the arc plate 83 close to the discharge barrel 6, and the push rod 88 is slidably connected to the filter hole 89. The push rod 88 includes multiple push rods 88 arranged in a rectangular shape, and there are no less than eight push rods 88.

[0063] Embodiment 2: Figure 9-11As shown, an anti-blocking component 8 is provided. When the screw rod 74 rotates, the screw rod 74 drives the upper and lower adjustment sleeves 81 to move. Since the internal threads of the upper and lower adjustment sleeves 81 are opposite, the upper and lower adjustment sleeves 81 will approach or move away from each other at the same time. When the upper and lower adjustment sleeves 81 approach each other, the adjustment sleeves 81 drive the side plates 82 to move. The side plates 82 slide inside the slide groove 87. The upper and lower side plates 82 respectively squeeze the upper and lower arc surfaces of the arc plate 83, so that the two arc plates 83 move away from each other. The arc plate 83 drives the sliding rod 85 to move. The sliding rod 85 slides into the fixed cylinder 84 and squeezes the spring 86. The arc plate 83 drives the push rod 88 to be pulled out of the filter hole 89.

[0064] When the upper and lower adjustment sleeves 81 move away from each other, the elastic force of the spring 86 drives the slide bar 85 and the arc plate 83 to reset, and the arc plate 83 drives the push rod 88 to insert into the filter hole 89, so that the push rod 88 cleans the filter hole 89, reducing the blockage of the filter hole 89, thereby improving the full reaction of the sewage with the treatment agent through the filter hole 89, thereby further improving the sewage treatment efficiency of the device.

[0065] Working principle: When using the device, first, Figure 1-Figure 11 As shown, alum or other treatment agent is put into the discharge barrel 6, and the discharge barrel 6 is inserted into the interior of the outer box body 3, and the arc plate 83 is kept between the upper and lower side plates 82, so that the insert block 78 is inserted into the slot 713 and fixed, and then the top cover 9 is pressed on the top of the discharge barrel 6, so that the block 71 is engaged with the slot 72, and the top cover 9 is fixed by bolts, and then the sewage to be treated is input through the water inlet pipe 4, and the reciprocating motor 73 is started to reciprocate, and the reciprocating motor 73 drives the screw rod 74 to rotate, and the screw rod 74 drives the stirring rod 75 to rotate, so that the sewage is contacted with the treatment agent through the filter hole 89 for purification, and the screw rod 74 drives the bottom rod 77 to rotate, and the bottom rod 77 drives the mounting column 712 and the rotating disk 711 to rotate, and the rotating disk 711 drives the shifting tooth 714 to rotate.

[0066] When rotating forward, the shifting tooth 714 is squeezed and rebounded by the inner teeth of the inner gear ring 717. At this time, the inner gear ring 717 and the upper turntable 715 do not rotate, and the rotating groove 716 corresponds to the position of the circulation groove 710, so that the sewage can flow into the filter screen plate 76 after treatment. The filter screen plate 76 can be made of activated carbon. After being treated by the filter screen plate 76, the sewage flows into the lower part of the discharge barrel 6 and is discharged from the drain pipe 5.

[0067] During reversal, the shifting tooth 714 is stuck on the inner teeth of the inner gear ring 717, so that the shifting tooth 714 drives the inner gear ring 717 to rotate together, and the inner gear ring 717 drives the upper turntable 715 to rotate, so that the rotating groove 716 is separated from the circulation groove 710. At this time, the sewage is blocked by the baffle 79 for a period of time, so that the sewage and the treatment agent are fully in contact. The intermittent water drop setting increases the contact time between the sewage and the treatment agent, thereby improving the sewage treatment and purification effect, and the discharge barrel 6 can be removed separately to facilitate the replacement of the internal treatment agent.

[0068] When the screw rod 74 rotates, the screw rod 74 drives the upper and lower adjustment sleeves 81 to move. Since the internal threads of the upper and lower adjustment sleeves 81 are opposite, the upper and lower adjustment sleeves 81 will approach or move away from each other at the same time. When the upper and lower adjustment sleeves 81 approach each other, the adjustment sleeves 81 drive the side plates 82 to move. The side plates 82 slide inside the slide grooves 87. The upper and lower side plates 82 respectively squeeze the upper and lower arc surfaces of the arc plates 83, so that the two arc plates 83 move away from each other. The arc plates 83 drive the sliding rod 85 to move. The sliding rod 85 slides into the fixed cylinder 84 and squeezes the spring 86. The arc plates 83 drive the push rod 88 to be pulled out of the filter hole 89.

[0069] When the upper and lower adjustment sleeves 81 move away from each other, the elastic force of the spring 86 drives the slide bar 85 and the arc plate 83 to reset, and the arc plate 83 then drives the push rod 88 to insert into the filter hole 89, so that the push rod 88 cleans the filter hole 89, reducing the blockage of the filter hole 89, thereby improving the full reaction of the sewage with the treatment agent through the filter hole 89.
