[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 , Figure 2As shown, this utility model provides a chemical agent dosing device for sewage treatment, including a agent dosing tank 1. A fixed platform 2 is fixedly installed on the top of the agent dosing tank 1. Four support rods 3 are fixedly installed in a rectangular array on the top of the fixed platform 2. A mixing tank bottom plate 4 is fixedly installed on the top of the four support rods 3. A chemical mixing tank 5 is fixedly installed on the top of the mixing tank bottom plate 4. A lifting drive box 6 is fixedly installed on the left side of the chemical mixing tank 5. A sewage inlet pipe 7 that penetrates the inner cavity of the agent dosing tank 1 is fixedly connected to the front end of the agent dosing tank 1. The rear end of the agent dispensing tank 1 is fixedly connected to a sewage dispensing pipe 8 that penetrates its inner cavity. A water pump 11 is installed between the agent mixing tank 5 and the fixed platform 2. The input end of the water pump 11 is fixedly connected to the bottom of the agent mixing tank 5 and penetrates its inner cavity. The output end of the water pump 11 penetrates the inner cavity of the agent dispensing tank 1 and is fixedly connected to an agent delivery pipe 111. The bottom end of the agent delivery pipe 111 is fixedly connected to an agent spraying box 112. Several nozzles 113 that penetrate its inner cavity are fixedly installed in a ring array on the outer wall of the agent spraying box 112.

[0023] In use, the sewage treatment pipeline can be connected to the sewage inlet pipe 7 at the front end of the agent dosing tank 1, so that the sewage passes through the sewage inlet pipe 7 and is then discharged into the sewage tank through the sewage dosing pipe 8. When discharging sewage, the chemical agent in the inner cavity of the agent mixing tank 5 can be extracted by starting the water pump 11 and input into the agent spray box 112 through the agent delivery pipe 111. With the water pressure generated by the water pump 11, the agent can be sprayed out through several nozzles 113, so that the agent is evenly mixed with the sewage passing through the inner cavity of the agent dosing tank 1 in a ring direction, ensuring that all sewage passing through the agent dosing tank 1 can be added with chemical agents for water purification.

[0024] like Figure 3 As shown, a sealing top cover 51 is provided above the inner cavity of the medicine mixing tank 5. Three medicine input pipes 511 that penetrate into the inner cavity of the medicine mixing tank 5 are fixedly connected to the top right side of the sealing top cover 51. Threaded sealing caps 512 are threadedly installed on the outer wall of each of the three medicine input pipes 511. A drain pipe 53 that penetrates the inner cavity is fixedly connected to the lower right side of the medicine mixing tank 5. A butterfly valve 531 is provided on the outer wall of the drain pipe 53. A servo motor 52 is fixedly installed at the top center of the sealing top cover 51. The output shaft of the servo motor 52 passes through to the bottom of the sealing top cover 51 and a rotating rod 521 is fixedly installed thereon. Several stirring blades 522 are fixedly installed in a ring array on the outer wall of the rotating rod 521.

[0025] Various different agents can be added into the inner cavity of the agent mixing tank 5 through three agent input pipes 511 after the threaded sealing cover 512 is opened by rotating. At this time, the servo motor 52 can be started to drive the rotating rod 521 and the stirring blade 522 to rotate quickly, so as to fully mix the added agents and make them ready for use. Wastewater generated during daily cleaning can be released from the drain pipe 53 by opening the butterfly valve 531.

[0026] like Figure 4 , Figure 5 As shown, a fixed base 61 is fixedly installed at the bottom of the lifting drive box 6. The fixed base 61 is fixedly installed on the lower left side of the medicine mixing tank 5. A servo motor 62 is fixedly installed at the bottom of the fixed base 61. The output shaft of the servo motor 62 passes through the inner cavity of the lifting drive box 6 and is fixedly installed with a lifting threaded rod 621. A lifting plate 622 is threaded onto the outer wall of the lifting threaded rod 621. Lifting upright plates 63 are fixedly installed on both the front and rear sides of the top of the lifting plate 622. The tops of the two lifting upright plates 63 pass through... A lifting plate 631 is fixedly installed on the top of the lifting drive box 6 and the top of the two lifting upright plates 63. A connecting hanging plate 632 is fixedly installed on the bottom right side of the lifting plate 631. The bottom of the connecting hanging plate 632 is fixedly connected to the top left side of the sealing top cover 51. A limiting ring 54 is fixedly installed above the inner ring of the medicine mixing tank 5. A rubber sealing ring 513 is fixedly installed on the bottom of the sealing top cover 51. The bottom of the rubber sealing ring 513 overlaps with the top of the limiting ring 54. The stirring blade 522 is located inside the limiting ring 54.

[0027] By activating the servo motor 62 located below the fixed base 61 at the bottom of the lifting drive box 6, the lifting plate 622, which is threaded onto the outer wall of the lifting threaded rod 621 inside the lifting drive box 6, can be raised. With the connection between the lifting plate 63 and the lifting plate 631, the connecting hanging plate 632 can be used to raise the sealing top cover 51 as a whole, which facilitates cleaning of the rotating rod 521 and the stirring blade 522 below the sealing top cover 51. At the same time, the inside of the tank can also be cleaned. After cleaning, the servo motor 62 can be activated to reverse its output shaft, which will drive the lifting threaded rod 621 to reverse, thereby allowing the sealing top cover 51 to gradually descend until the rubber sealing ring 513 at the bottom of the sealing top cover 51 stops against the top of the limiting ring 54. The rubber sealing ring 513 can improve the sealing performance of the sealing top cover 51 after it is closed.

[0028] The working principle of the chemical dosing device for wastewater treatment will be explained in detail below.

[0029] like Figure 1-5As shown, during use, the sewage treatment pipeline can be connected to the sewage inlet pipe 7 at the front end of the agent dosing tank 1, so that the sewage passes through the sewage inlet pipe 7 and is then discharged into the sewage tank through the sewage dosing pipe 8. When discharging sewage, simply start the water pump 11 to extract the chemical agent from the inner cavity of the agent mixing tank 5 and input it into the agent spray box 112 through the agent delivery pipe 111. With the water pressure generated by the water pump 11, the agent can be sprayed out through several nozzles 113, so that the agent is evenly mixed with the sewage passing through the inner cavity of the agent dosing tank 1 in a ring direction, ensuring that all sewage passing through the agent dosing tank 1 can be added with chemical agents for water purification. At the same time, multiple different agents can be added into the inner cavity of the agent mixing tank 5 by rotating and opening the threaded sealing cover 512 and then entering through three agent input pipes 511. At this time, starting the servo motor 52 will drive the rotating rod 521 and the stirring blade 522 to rotate rapidly, so as to fully mix the added agents and make them ready for rapid dosing. When the tank is in use, the wastewater generated during daily cleaning can be released from the drain pipe 53 by opening the butterfly valve 531. When the chemical mixing tank 5 needs to be cleaned after long-term use, simply start the servo motor 62 under the fixed base 61 at the bottom of the lifting drive box 6. This will drive the lifting plate 622, which is threaded on the outer wall of the lifting threaded rod 621 inside the lifting drive box 6, to rise. With the connection between the lifting plate 63 and the lifting plate 631, the connecting hanging plate 632 can be used to drive the sealing top cover 51 to rise as a whole, which is convenient for cleaning the rotating rod 521 and the stirring blade 522 under the sealing top cover 51. At the same time, the inside of the tank can also be cleaned. After cleaning, the servo motor 62 can be started to reverse its output shaft, which will drive the lifting threaded rod 621 to reverse, so that the sealing top cover 51 will gradually descend until the rubber sealing ring 513 at the bottom of the sealing top cover 51 stops against the top of the limiting ring 54. The rubber sealing ring 513 can improve the sealing performance of the sealing top cover 51 after it is closed.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
