[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0021] See also Figure 1-4 In this embodiment: a drug additive for sewage treatment comprises a sewage treatment pool 1, a base 5 is fixedly installed at the bottom of the sewage treatment pool 1, a motor assembly 4 is fixedly installed at the top center of the base 5, a rotating drum 2 is rotatably installed on the top of the motor assembly 4, and a plurality of symmetrically distributed distributing mechanisms 3 are installed on the side of the rotating drum 2, and the distributing mechanisms 3 comprise distributing pipes 31 fixedly plugged and installed on the side of the rotating drum 2, and there are a plurality of distributing pipes 31 and the distributing pipes 31 are obliquely plugged and installed on the side of the rotating drum 2, and the end of the distributing pipe 31 close to the rotating drum 2 is higher than the end of the distributing pipe 31 away from the rotating drum 2. When in use, the drug for sewage treatment is filled into the rotating drum 2 from the top of the rotating drum 2. , until it is filled, so that the distribution pipe 31 will also be filled when the sealing block 32 is blocked, and then the sewage to be treated is filled into the sewage treatment tank 1, and the driving motor is started to rotate the rotating drum 2, and the rotating drum 2 drives the distribution pipe 31 to rotate. As the speed increases, under the action of centrifugal force, the sealing block 32 gradually moves away from the distribution pipe 31, and the distribution trough 33 opens. The medicine is scattered throughout the sewage treatment tank 1 along the distribution pipe 31. Such a design not only makes the distribution of the medicine in the sewage treatment tank 1 more uniform, but also realizes the stirring and mixing of the sewage and the medicine through the rotation of the distribution pipe 31, so that the reaction between the medicine and the sewage is faster, and the efficiency of drug addition and sewage treatment is further improved.

[0022] As a preferred embodiment, the motor assembly 4 includes a driving motor and a protective cover fixedly installed around the driving motor. The output end of the driving motor extends to the outside of the protective cover and is fixedly connected to the bottom of the rotating drum 2. A waterproof sealing ring is installed at the connection between the protective cover and the output end of the driving motor, which can prevent water from entering the driving motor and protect the driving motor.

[0023] As a preferred embodiment, Figure 3 As shown, a distribution groove 33 is provided on the inner side of the distribution pipe 31, and the distribution groove 33 is connected to the inner side of the rotating cylinder 2. When the medicine is added into the rotating cylinder 2, the medicine will also fill up the distribution groove 33. At the same time, when the distribution pipe 31 rotates, the medicine in the distribution groove 33 is scattered, and the medicine in the rotating cylinder 2 will be dispersed along the distribution groove 33. Example

[0024] See also Figure 1-4 In this embodiment, a sliding circular groove 34 is provided at one end of the material distribution tube 31 away from the rotating cylinder 2 and located on the side of the material distribution groove 33, a sliding rod 35 is slidably inserted and installed on the inner side of the sliding circular groove 34, and one end of the sliding rod 35 away from the sliding circular groove 34 extends to the outside of the material distribution tube 31 and is fixedly installed with a sealing block 32. When the material distribution tube 31 rotates, the sliding rod 35 will slide in the sliding circular groove 34 under the action of centrifugal force, and the sealing block 32 will gradually move away from the end of the material distribution tube 31, so that the material distribution groove 33 is opened, and the medicine is thrown out of the material distribution groove 33 and scattered around the rotating cylinder 2;

[0025] As a preferred embodiment, Figure 4 As shown, a fixed block 37 is fixedly installed on the inner side of the sliding circular groove 34, and a tension spring 36 is fixedly installed at the end of the fixed block 37 and the sliding rod 35 and on the inner side of the sliding circular groove 34. After all the drugs are scattered in the sewage treatment tank 1, the driving motor is stopped and the centrifugal force disappears. Under the action of the tension spring 36, the sliding rod 35 moves in the reverse direction to drive the sealing block 32 to block the distribution trough 33 again, which is convenient for the next addition of drugs, the recycling of the equipment and the continuity of sewage treatment.

[0026] As a preferred embodiment, Figure 2 As shown, the distribution pipes 31 are evenly spaced from top to bottom around the rotating drum 2 to ensure that the drugs can be distributed more quickly to various places in the sewage treatment tank 1 after being scattered.

The sealing block 32 can block the distribution trough 33 to ensure the orderliness and controllability of drug addition. When the driving motor stops, the drug will no longer be added.

[0028] The working principle and use process of the utility model are as follows: the operator starts the driving motor to rotate the rotating drum 2, and the rotating drum 2 drives the distribution pipe 31 to rotate. As the speed increases, under the action of centrifugal force, the sealing block 32 gradually moves away from the distribution pipe 31, the distribution trough 33 opens, and the medicine is scattered throughout the sewage treatment pool 1 along the distribution pipe 31. Such a design not only makes the distribution of the medicine in the sewage treatment pool 1 more uniform, but also realizes the stirring and mixing of sewage and medicine through the rotation of the distribution pipe 31, so that the reaction of medicine and sewage is faster, and the efficiency of drug addition and sewage treatment is further improved. By setting the sealing block 32 and the stretching spring 36, the amount of drug addition can be controlled. At the same time, under the action of the stretching spring 36, the sliding rod 35 moves in the opposite direction to drive the sealing block 32 to block the distribution trough 33 again, which is convenient for the next drug addition, the recycling of the equipment and the continuity of sewage treatment.
