Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-5 As shown, a wastewater dosing and stirring device includes a motor 11, a rotating shaft 12 fixedly connected to the output end of the motor 11, and a stirring blade 14 fixedly connected to the end of the rotating shaft 12; a casing 13 fixedly connected to the end of the motor 11, an impeller 15 fixedly connected to the rotating shaft 12, the impeller 15 being located inside the casing 13, a vertical pipe 16 fixedly connected to the top of the casing 13, the vertical pipe 16 communicating with the casing 13, the vertical pipe 16 being located on the side of the impeller 15 away from the stirring blade 14, a cylinder 17 fixedly connected to the end of the casing 13, the stirring blade 14 being located inside the cylinder 17, and a steel cable fixedly connected to the motor 11.

[0024] In use, the output end of the motor 11 is connected to a rotating shaft 12, and a stirring blade 14 and an impeller 15 are fixedly connected to the rotating shaft 12. The impeller 15 is installed inside the casing 13, and a vertical pipe 16 is fixedly connected to the casing 13. When the impeller 15 rotates, it will create a negative pressure on the side near the vertical pipe 16. The sewage treatment agent is put into the interior of the vertical pipe 16. The sewage and the agent enter the interior of the casing 13 from the vertical pipe 16. The impeller 15 drives the agent and sewage to flow towards the stirring impeller 15. The stirring impeller 15 stirs the sewage and disperses the agent, thereby improving the uniformity of the mixing of the agent and sewage.

[0025] Furthermore, such as Figure 1-5 As shown, the motor 11 has support arms 21 fixedly connected to both sides, and a sliding sleeve 22 fixedly connected to the end of the support arm 21. The sliding sleeve 22 has a column 23 inside, and the column 23 and the sliding sleeve 22 are slidably connected.

[0026] In use, the column 23 is installed inside the sewage treatment tank, and the end of the motor 11 is equipped with a support arm 21. The support arm 21 slides on the column 23 through the sliding sleeve 22. The sliding sleeve 22 and the column 23 cooperate to guide and improve the stability of the up and down movement. The pull rope is installed on the external winch to adjust the height of the motor 11 and the stirring blade 14.

[0027] Furthermore, such as Figure 1-5 As shown, a telescopic tube 31 is sleeved on the surface of the vertical tube 16. The telescopic tube 31 is connected to the vertical tube 16. A feed seat 32 is fixedly connected to the top of the telescopic tube 31. A water inlet pipe 33 is fixedly connected to the feed seat 32. A bracket is fixedly connected to the top of the feed seat 32. A float ball 53 is fixedly connected to the bracket.

[0028] During use, a telescopic pipe 31 is installed at the top of the vertical pipe 16, and a feed seat 32 is fixedly connected to the top of the telescopic pipe 31. A float ball 53 is installed on the feed seat 32, so that the feed seat 32 floats on the water surface, making it convenient for workers to put the agent into the feed seat 32. The feed seat 32 has multiple water inlet pipes 33 on its side. Water enters the feed seat 32 from the water inlet pipes 33, thereby impacting the agent and thus initially mixing the agent and sewage, improving the mixing effect.

[0029] Furthermore, such as Figure 1-5 As shown, multiple water inlet pipes 33 are provided, and the multiple water inlet pipes 33 are arranged in a ring array. The water inlet pipes 33 are located on the tangent of the cross section of the feed seat 32. A top cover 42 is fixedly connected to the top of the feed seat 32, and a feeding hose 41 is fixedly connected to the top of the top cover 42. The support includes a fixing ring 51 and multiple support rods 52. The fixing ring 51 is fixedly connected to the top of the feed seat 32, and the multiple support rods 52 are arranged in a ring and fixedly connected to the fixing ring 51. The float ball 53 is fixedly connected to the end of the support rod 52.

[0030] In use, multiple water inlet pipes 33 are arranged in a ring and located on the tangent of the feed seat 32. This allows water to enter and creates a rotating vortex inside, which facilitates thorough mixing of water and wastewater treatment agents.

[0031] Furthermore, when the surface of the sewage is a certain distance from the edge of the sewage tank, a feeding hose 41 is installed on the top of the feeding seat 32 through the top cover 42. The staff can put the medicine into the feeding hose 41, thereby putting the medicine into the inside of the feeding seat 32 for easy use. Multiple ring-shaped support rods 52 are set on the support, which are connected to the float 53 to improve the uniformity of buoyancy distribution.

[0032] Furthermore, such as Figure 1-5 As shown, the float 53 is made of plastic and has a cavity inside.

[0033] Working principle: During use, the output end of the motor 11 is connected to the rotating shaft 12. The rotating shaft 12 is fixedly connected to the stirring blade 14 and the impeller 15. The impeller 15 is installed inside the casing 13. The casing 13 is fixedly connected to the vertical pipe 16. When the impeller 15 rotates, it will create a negative pressure on the side near the vertical pipe 16. The sewage treatment agent is put into the interior of the vertical pipe 16. The sewage and the agent enter the interior of the casing 13 from the vertical pipe 16. The impeller 15 drives the agent and sewage to flow towards the stirring impeller 15. The stirring impeller 15 stirs the sewage and disperses the agent, thereby improving the uniformity of the mixing of the agent and sewage.

[0034] In use, the column 23 is installed inside the sewage treatment tank. A support arm 21 is installed at the end of the motor 11. The support arm 21 slides on the column 23 via a sliding sleeve 22. The sliding sleeve 22 and the column 23 cooperate to guide the movement and improve stability. A pull rope is installed on an external winch to adjust the height of the motor 11 and the stirring blade 14. During use, a telescopic pipe 31 is installed at the top of the vertical pipe 16. A feed seat 32 is fixed to the top of the telescopic pipe 31, and a float 53 is installed on the feed seat 32, allowing it to float. The feed seat 32 is positioned on the water surface, allowing staff to easily add chemicals into the feed unit 32. Multiple water inlet pipes 33 are located on the side of the feed seat 32, through which water enters the feed seat 32, impacting the chemicals and thus initially mixing them with the wastewater to improve the mixing effect. During use, the multiple water inlet pipes 33 are arranged in a ring and located tangentially to the feed seat 32, creating a vortex inside the feed seat 32 to facilitate thorough mixing of the water and wastewater treatment chemicals.

[0035] Furthermore, when the surface of the sewage is a certain distance from the edge of the sewage tank, a feeding hose 41 is installed on the top of the feeding seat 32 through the top cover 42. The staff can put the medicine into the feeding hose 41, thereby putting the medicine into the inside of the feeding seat 32 for easy use. Multiple ring-shaped support rods 52 are set on the support, which are connected to the float 53 to improve the uniformity of buoyancy distribution.
