Sewage includes industrial sewage and domestic sewage. If sewage is not completely purified and is directly discharged, it will re-enter the earth's water cycle system, destroying the ecological environment. In addition, sewage will enter the human body and affect human health.

[0003] The patent with patent announcement number CN218232001U discloses a dosing sewage treatment device for sewage treatment, including a treatment box, a dosing pipe, a rotating shaft, a medicine dividing plate and a stirring assembly. The bottom end of the dosing pipe is arranged on the side wall of the treatment box and is connected to the treatment box. The two sides of the middle part of the dosing pipe are arranged in an arc structure. The rotating shaft is rotatably arranged on the inner side wall of the middle part of the dosing pipe. The medicine dividing plate is arranged on the rotating shaft and is evenly arranged in multiple groups. The medicine dividing plate is rotatably arranged in the middle part of the medicine inlet pipe. The side wall of the medicine inlet pipe is provided with a driving motor 1. The output end of the driving motor 1 rotates through the medicine inlet pipe and is connected to the rotating shaft. The stirring assembly is arranged on the treatment box.

[0004] However, the current sewage treatment device has the following problems: when treating sewage, the sewage treatment device directly sprays the treatment agent that reacts with the sewage into the sewage. However, in this process, adding too much treatment agent at one time will cause uneven diffusion, thereby reducing the treatment rate of sewage treatment. Therefore, we propose a sewage treatment device with a medicated agent for sewage treatment. Summary of the invention

The bottom of the T-shaped plate is in contact with the bottom of the liquid receiving tray. At the same time, the rotating rod drives the sleeve to rotate during the rotation of the rotating rod, and the sleeve drives the T-shaped plate to rotate. When the T-shaped plate moves to the circular mouth position, the circular mouth will be blocked by the T-shaped plate, and the treatment agent will not be discharged through the circular mouth at this time. When the T-shaped plate moves out to the circular mouth position, the treatment agent can be discharged through the circular mouth.

Since the position of the thread ring is restricted by the fixed strip and the liquid receiving box, the thread groove drives the thread ring to drive the cross plate and the liquid receiving box to move downward along the outer wall of the fixed strip. When the output shaft of the motor is reversed, the output shaft of the motor drives the stirring blade rod to reverse, and the stirring blade rod drives the thread groove to reverse. At this time, the thread groove drives the thread ring to drive the cross plate and the liquid receiving box to move upward along the outer wall of the fixed strip. Every time the liquid receiving box moves upward, the liquid receiving box drives the top of the push rod to contact the horizontal bar of the round mouth, and the push rod moves downward. The push rod drives plug disc 1 and plug disc 2 to move downward. Plug disc 1 no longer blocks the round hole at the top of the liquid receiving box, and plug disc 2 no longer blocks the round hole at the bottom of the liquid receiving box.

A plurality of stirring blades 10 are fixed to the outer wall of the rotating rod 9. Through the arrangement of the above structure, the circular mouth 14 disperses the treatment agent in the sewage, thereby avoiding the problem that too much treatment agent is added at one time, which will cause uneven diffusion and thus reduce the sewage treatment rate. Through the arrangement of the above structure, the stirring blades 10 stir the treatment agent at the liquid receiving tray 6, thereby avoiding the problem of precipitation of the treatment agent at the liquid receiving tray 6, ensuring that the particles in the treatment agent are in a suspended state, which is beneficial for the treatment agent to treat the sewage.

[0017] A sleeve 12 is sleeved on the outer wall of the rotating rod 9 away from the stirring blade 5, and a T-shaped plate 13 is fixed to the bottom of the sleeve 12. The bottom of the T-shaped plate 13 contacts the bottom of the liquid receiving tray 6. Through the arrangement of the above structure, the treatment agent is intermittently discharged through the circular opening 14, thereby avoiding the problem of uneven diffusion caused by adding too much treatment agent at one time.

[0018] When in use, sewage is put into the device body 1 through the sewage pipe 3, and the treatment agent is put into the device body 1 through the feed pipe 2. The treatment agent will first fall on the liquid receiving tray 6, and then fall into the sewage in the device body 1 through the circular mouth 14. The stirring blade rod 5 is driven by the motor to rotate, and the stirring blade rod 5 will stir and mix the treatment agent and sewage, so that the treatment agent treats the sewage.

[0022] A turning device 8 for turning over the sewage at the side wall of the device body 1 is provided below the top rod 75. The turning device 8 includes a turning ring 81, eight fixing frames 82, four friction wheels 83, and eight blade wheels 84. The turning ring 81 is fixed between the bottoms of the four top rods 75, and the eight fixing frames 82 are evenly and equidistantly fixed on the top of the turning ring 81. The four friction wheels 83 are rotatably installed between two adjacent fixing frames 82, and the outer wall of the friction wheel 83 contacts the inner wall of the device body 1. The eight blade wheels 84 are respectively fixed at both ends of the rotating shaft of the friction wheel 83. Through the arrangement of the above structure, the turning ring 81 turns the treatment agent at the edge of the device body 1 toward the direction of the stirring blade rod 5, thereby avoiding the problem of the treatment agent accumulating at the edge of the device body 1 and affecting the mixing of the treatment agent and sewage.

[0023] The flipping device 8 also includes eight elastic telescopic rods 85, eight column rods 86, eight knocking rods 87, and eight convex wheel 88.

Through the arrangement of the above structure, the column rod 86 drives the knocking rod 87 to knock the flipping ring 81, the flipping ring 81 vibrates, and the flipping ring 81 shakes off the flocs adhering to it, thereby avoiding the problem of flocs adhering to the flipping ring 81 and the treatment agent falling on the flocs of the flipping ring 81 and sticking into a ball.

[0024] When the motor is in use, the motor corresponding to the stirring blade rod 5 is in the forward and reverse rotation position. When the output shaft of the motor rotates forward, the output shaft of the motor drives the stirring blade rod 5 to rotate forward, and the stirring blade rod 5 drives the thread groove 73 to rotate forward. Since the position of the threaded ring 71 is restricted by the fixing strip 76 and the liquid receiving box 74, the threaded groove 73 drives the threaded ring 71 to drive the cross plate 72 and the liquid receiving box 74 to move downward along the outer wall of the fixing strip 76. When the output shaft of the motor is reversed, the output shaft of the motor drives the stirring blade rod 5 to reverse, and the stirring blade rod 5 drives the threaded groove 73 to reverse. At this time, the threaded groove 73 drives the threaded ring 71 to drive the cross plate 72 and the liquid receiving box 74 The liquid box 74 moves upward along the outer wall of the fixing strip 76. Each time the liquid receiving box 74 moves upward, the liquid receiving box 74 drives the top of the push rod 75 to collide with the horizontal strip of the round opening 14, and the push rod 75 moves downward.

When the liquid receiving box 74 moves downward, When the push rod 75 moves to the bottom position of the inner wall of the device body 1, the bottom of the inner wall of the device body 1 moves upward against the push rod 75, and the push rod 75 drives the plug disc 1 77 and the plug disc 2 79 to move upward, and the plug disc 2 79 no longer blocks the bottom of the liquid receiving box 74. The treatment agent in the liquid receiving box 74 flows out and diffuses from the circular hole of the liquid receiving box 74, so that the treatment agent is released in the lower layer of the sewage, ensuring that the sewage and the treatment agent are mixed more evenly, which is beneficial for the treatment agent to treat the sewage; at the same time, when the top rod 75 moves upward, it will drive the spiral groove 713 to move synchronously, and the spiral groove 713 drives the rotating ring 711 to rotate at the bottom of the U-shaped disc frame 710, and the rotating ring 711 drives the fanning blade 712 to rotate, so that the fanning blade 712 stirs the treatment agent flowing out of the circular hole of the liquid receiving box 74, thereby promoting the mixing efficiency of the lower layer treatment agent and sewage.

Under the friction force between the friction wheel 83 and the device body 1, the device body 1 drives the friction wheel 83 to rotate, and the friction wheel 83 drives the blade wheel 84 to rotate. The blade wheel 84 will further flip the treatment agent at the edge of the device body 1 toward the direction of the stirring blade rod 5, and at the same time, the blade wheel 8 4 will drive the convex wheel 88 to rotate, the convex block of the convex wheel 88 pushes the circular surface of the column 86 to drive the column 86 to move upward, the column 86 drives the telescopic end of the elastic telescopic rod 85 to stretch and drives the knocking rod 87 away from the flip ring 81, when the convex block of the convex wheel 88 does not push the circular surface of the column 86, under the elastic force of the elastic telescopic rod 85, the elastic telescopic rod 85 drives the column 86 to reset, the column 86 drives the knocking rod 87 to knock the flip ring 81, the flip ring 81 vibrates, and the flip ring 81 shakes off the flocs adhering to it, thereby avoiding the problem of flocs adhering to the flip ring 81 and the treatment agent falling on the flocs of the flip ring 81 and bonding into a ball.
