Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a wastewater treatment agent dosing device for wastewater treatment. Background Technology

[0002] Wastewater treatment is the process of removing harmful substances from wastewater, making it safe for discharge or recycling. It involves adding chemical agents to wastewater to promote the removal or degradation of pollutants. These agents can help accelerate the settling of sediments, improve the turbidity of wastewater, adjust the pH or redox conditions of wastewater, and inhibit or kill microorganisms.

[0003] Chinese patent CN214059944U discloses a dosing tank for a water purification agent used in papermaking wastewater treatment. The tank includes a body, a measuring ruler fixedly connected to the middle of the right end of the body, a feed pipe fixedly connected to the upper left end of the body, a diverter fixedly connected to the outer surface of the feed pipe's front end, a water inlet pipe fixedly connected to the front upper end of the body, the lower end of the water inlet pipe penetrating the front upper end of the body and extending into the body, a motor fixedly connected to the middle of the upper end of the body, and a stirring device fixedly connected to the motor's output end penetrating the middle of the upper end of the body. A discharge pipe is fixedly connected to the rear right end of the body, and a water pump is fixedly connected to the middle of the discharge pipe. By incorporating the stirring device, the rotation of a rotating rod causes the first and second stirring blades to rapidly agitate within the tank, quickly dissolving the water purification agent and ensuring thorough mixing and blending of water and the agent.

[0004] In current technology, the reagent enters through the feed pipe. However, during the stirring process, the liquid inside the tank is prone to splashing onto the bottom of the feed pipe, and the reagent will adhere to the bottom of the feed pipe. Over time, scale will form and block the feed pipe, thus affecting the addition of the reagent.

[0005] Therefore, a wastewater treatment agent dosing device is proposed to address the above problems. Utility Model Content

[0025] Specific implementation examples are given below.

Four storage tanks 3 are connected and fixedly connected to the top of the mixing tank 1. A second motor 4 is fixedly connected to the top of the mixing tank 1. A rotating rod 41 is fixedly connected to the output shaft of the second motor 4. The top of the rotating rod 41 is rotatably connected to the mixing tank 1. A first gear 42 is fixedly connected to the outer wall of the top of the rotating rod 41. Three of the storage tanks 3 are used to hold powdered agents, and their bottoms extend into the mixing tank 1 and are rotatably connected to a second gear 43. The second gear 43 meshes with the first gear 42. A scraper 44 is fixedly connected to the inner wall of the second gear 43, and the scraper 44 contacts the inner wall of the storage tank 3.

[0027] Wastewater treatment is the process of removing harmful substances from wastewater, making it safe for discharge or recycling. This involves adding chemical agents to the wastewater to promote the removal or degradation of pollutants. These agents can help accelerate the settling of sediments, improve wastewater turbidity, adjust the pH or redox conditions of the wastewater, and inhibit or kill microorganisms. During operation, to prevent the agents from adhering to the bottom of the storage tank 3 and clogging the inlet pipe, the second motor 4 needs to be activated during the discharge process. The second motor 4 not only starts the... The mixing and stirring of the stirring blades 46 in the mixing tank 1 also drives the first gear 42 to rotate via the rotating rod 41. The first gear 42 drives the second gear 43 to rotate. During the rotation of the second gear 43, the scraper 44 rotates, scraping off the powder at the bottom of the medicine storage tank 3 to prevent scaling and clogging. Three of the medicine storage tanks 3 contain powdered treatment agents, and the other medicine storage tank 3 contains liquid treatment agents. The liquid medicine storage tank 3 is located near the water inlet pipe 2. The treatment agents include flocculants, neutralizers, etc.

[0028] Furthermore, such as Figure 1 and Figure 2 As shown, the top of each medicine storage tank 3 is connected to a feed hopper 33, and the bottom of each medicine storage tank 3 is equipped with a second control valve 32; a distance sensor 34 is fixedly connected to the inner wall of the top of each medicine storage tank 3, and a first motor 31 is fixedly connected to the top of each medicine storage tank 3. The output shaft of the first motor 31 is fixedly connected to a vertical rod, and a spiral blade and a stirring paddle are fixedly connected to the outer wall of the vertical rod, respectively.

[0029] During operation, the powdered treatment agent needs to be unblocked by the spiral blades when it is fed, and the liquid treatment agent needs to be mixed evenly by the agitator before it is fed. A distance sensor 34 is set to monitor the feeding amount, so as to control the output of the treatment agent. When the distance sensor 34 reaches the set value, it transmits the signal to the system, and the system controls the second control valve 32 to close.

[0030] Furthermore, such as Figure 2 As shown, a water inlet pipe 2 is connected and fixed to the top side wall of the mixing tank 1, and a flow meter 21 and a first control valve 22 are installed on the water inlet pipe 2.

[0031] During operation, wastewater is fed into the mixing tank 1 through the inlet pipe 2. The flow meter 21 monitors the amount of wastewater entering the tank. Once the set flow rate is reached, the system controls the first control valve 22 to close and stop the flow.

[0032] Furthermore, such as Figure 4As shown, multiple stirring blades 46 are fixedly connected to the outer wall of the rotating rod 41, and two rotating frames 45 are fixedly connected to the middle of the rotating rod 41; two connecting pipes 452 are fixedly connected to the side wall of each rotating frame 45, and connecting blocks 453 are slidably connected inside each connecting pipe 452. A cleaning brush 451 is fixedly connected to the side of each connecting block 453 near the inner wall of the mixing tank 1, and a spring 454 is fixedly connected between each connecting block 453 and the rotating frame 45.

[0033] During operation, the treatment agent and sewage are mixed by the stirring blades 46, so that the sewage and treatment agent can fully contact and react. The rotating rod 41 drives the rotating frame 45 to rotate, and the rotating frame 45 drives the cleaning brush 451 to rotate, cleaning the inner wall of the mixing tank 1. The spring 454 is provided to facilitate the buffering of the spring 454 and reduce the wear of the cleaning brush 451.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, the bottom of the mixing tank 1 is connected to and fixedly connected to a discharge pipe 5 via an adapter. A first solenoid valve 51 and a third solenoid valve 53 are respectively installed at both ends of the discharge pipe 5. A drain pipe 54 is connected and fixedly connected to the middle of the discharge pipe 5. A second solenoid valve 52 is installed on the drain pipe 54. A filter plate 55 is fixedly connected to the inner wall of the top end of the drain pipe 54.

[0035] During operation, the treated wastewater is discharged from the discharge pipe 5 by opening the first solenoid valve 51. At this time, the third solenoid valve 53 is closed and the second solenoid valve 52 is opened. Under the action of the filter plate 55, the wastewater is discharged from the drain pipe 54. When the water in the mixing tank 1 reaches a certain amount, the third solenoid valve 53 is opened, and the impurities flow with the wastewater to the designated position.

[0036] Working principle: To solve the problem of the agent adhering to the bottom of the storage tank 3 and clogging the feed pipe, the second motor 4 needs to be turned on during the discharge process of the agent in the storage tank 3. The second motor 4 not only starts the mixing of the stirring blades 46 in the mixing tank 1, but also drives the first gear 42 to rotate through the rotating rod 41. The first gear 42 drives the second gear 43 to rotate. During the rotation of the second gear 43, the scraper 44 rotates and scrapes off the powder at the bottom of the storage tank 3 to prevent scaling and blockage. Three of the storage tanks 3 contain powdered treatment agents, and the other storage tank 3 contains liquid treatment agents. The storage tank 3 containing liquid treatment agents is located near the water inlet pipe 2. The treatment agents include flocculants, neutralizers, etc.

[0037] When the powdered treatment agent is fed, it needs to be cleared by the spiral blades. The liquid treatment agent needs to be mixed evenly by the agitator before feeding. A distance sensor 34 is set to monitor the feeding amount, so as to control the output of the treatment agent. When the distance sensor 34 reaches the set value, the signal is transmitted to the system, and the system controls the second control valve 32 to close.

[0038] The treatment agent and sewage are mixed by the stirring blades 46, so that the sewage and treatment agent can fully contact and react. The rotating rod 41 drives the rotating frame 45 to rotate, and the rotating frame 45 drives the cleaning brush 451 to rotate, cleaning the inner wall of the mixing tank 1. A spring 454 is provided to facilitate the buffering of the spring 454 and reduce the wear of the cleaning brush 451.

[0039] The treated wastewater is discharged from the discharge pipe 5 by opening the first solenoid valve 51. At this time, the third solenoid valve 53 is closed and the second solenoid valve 52 is opened. Under the action of the filter plate 55, the wastewater is discharged from the drain pipe 54. When the water in the mixing tank 1 reaches a certain amount, the third solenoid valve 53 is opened, and the impurities flow with the wastewater to the designated position.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
