Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically a free chlorine removal device. Background Technology

[0002] When tap water is used directly for raising fish or watering plants, the free chlorine in it can damage the fish and plants. Therefore, dechlorination equipment is needed to remove the chlorine from the water. Tap water is usually dechlorinated by letting it stand and being exposed to sunlight, but the dechlorination speed is relatively slow.

[0003] Chinese patent discloses a water residual chlorine removal pretreatment device (authorization announcement number CN219239367U). In this patented technology, an air pump can inject air into the settling tank through an aeration disc. The air will form microbubbles under the action of the aeration disc. The bubbles will roll and rise in the settling tank. The dechlorinating agent is poured into the dosing funnel. The dosing valve is opened, and the dechlorinating agent will be added into the settling tank. The drive motor drives the stirring paddle to rotate. The stirring paddle stirs the water and bubbles, which can further improve the mixing of air and water and further improve the dechlorination effect of the water.

[0004] However, it has certain drawbacks: its stirring paddle, like traditional stirring methods, can only stir in a single horizontal direction, which limits the mixing range and leads to uneven mixing of materials. In particular, mixing dead zones are prone to appear near the bottom and top of the container, which will reduce the overall mixing efficiency and thus require a longer stirring time to achieve the desired mixing effect.

[0022] Please see Figures 1-3 In this embodiment of the present invention, a free chlorine removal device includes a dechlorination tank body 1, a tank cover 2 fixedly connected to the upper end of the dechlorination tank body 1, a dosing hopper 3 penetratingly connected to the right side of the upper surface of the tank cover 2, and a horizontal plate 4 installed above the tank cover 2. A first motor 5 is fixedly connected to the upper surface of the horizontal plate 4, and a stirring rod 6 is fixedly connected to the output end of the first motor 5. The stirring rod 6 movably penetrates the tank cover 2.

[0023] A lifting mechanism 7 is provided at the connection between the can lid 2 and the horizontal plate 4. The lifting mechanism 7 includes a vertical plate 8. The lower end of the vertical plate 8 is fixed to the upper surface of the can lid 2. A second motor 9 is fixed to the rear surface of the vertical plate 8. A first gear 10 is fixed to the output end of the second motor 9. A rotating rod 11 is rotatably connected to the front surface of the vertical plate 8 below the first gear 10. A second gear 12 is fixed to the outside of the rotating rod 11. The first gear 10 is meshed with the second gear 12. A turntable 13 is fixed to the outside of the rotating rod 11 in front of the second gear 12. A lifting component 14 is provided on the front surface of the vertical plate 8 above the first gear 10. The lifting component 14 includes a sliding rod 15. The upper end of the sliding rod 15 is fixed to the lower surface of the horizontal plate 4. A slider 16 is slidably connected to the outside of the sliding rod 15. The rear end of the slider 16 is fixed to the front surface of the vertical plate 8. A rotating plate 17 is rotatably connected to the lower end of the front surface of the sliding rod 15. The lower end of the rotating plate 17 is rotatably connected to the outer edge of the front surface of the turntable 13.

[0024] The material to be dechlorinated is placed in tank 1 of the dechlorination tank;

[0025] A colorless transparent plate is connected through the left side surface of the dechlorination tank 1 to allow sunlight to shine on the material to be dechlorinated, thus accelerating the volatilization of free chlorine.

[0026] The dechlorination tank body 1 and the tank cover 2 are fixed together by a detachable means such as a lock;

[0027] The dosing hopper 3 is used to hold dechlorination agents, and a removable cover is placed on the top of the dosing hopper 3;

[0028] The first motor 5 drives the stirring rod 6 to rotate and stir the material to be dechlorinated and the dechlorination agent, thereby accelerating the mixing efficiency. The stirring can also generate bubbles, which accelerates the volatilization of free chlorine.

[0029] The second motor 9 is equipped with a brake, meaning that the motor shaft cannot rotate after the power is cut off;

[0030] When the turntable 13 rotates, it can cause the rotating plate 17 to swing and generate displacement, thereby causing the slide rod 15 to move up and down repeatedly, and in turn causing the stirring rod 6 to move up and down repeatedly. This allows the stirring rod 6 to move horizontally while also generating vertical displacement, increasing the mixing range and reducing mixing dead zones.

[0031] exist Figure 1 and Figure 4 In the middle: A gas supply mechanism 18 is provided on the right side surface and inside the dechlorination tank body 1. The gas supply mechanism 18 includes a support plate 19. The left end of the support plate 19 is fixed to the right side surface of the dechlorination tank body 1. A fan 20 is fixed to the upper surface of the support plate 19. A first pipe 21 is fixed to the air outlet end of the fan 20. The first pipe 21 passes through and is connected to the support plate 19. A valve 22 is fixed to the lower end of the first pipe 21. A second pipe 23 is fixed to the left end of the valve 22. The second pipe 23 passes through and is connected to the right side surface of the dechlorination tank body 1. A fan coil 24 is fixed to the outside of the left end of the second pipe 23. The fan coil 24 is fixed to the lower inner surface of the dechlorination tank body 1. Multiple one-way nozzles 25 are fixed to the upper surface of the fan coil 24.

[0032] The air pressure generated by fan 20 is greater than the water pressure;

[0033] The blower 20 draws air from the outside, and the airflow is sprayed out through the one-way nozzle 25, causing the material to be dechlorinated to churn and generate a large number of bubbles, which not only accelerates the volatilization of free chlorine, but also further improves the mixing efficiency of the material to be dechlorinated and the dechlorination agent.

[0034] The working principle of this utility model is as follows: In use, the material to be dechlorinated is poured into the dechlorination tank 1 through the dosing hopper 3, and then the dechlorination agent is poured into the dechlorination tank 1 through the dosing hopper 3. The first motor 5 is turned on to drive the stirring rod 6 to rotate and stir the material to be dechlorinated and the dechlorination agent. The second motor 9 drives the first gear 10 to rotate, and the second gear 12 drives the rotating rod 11 to rotate. This causes the rotating plate 17 to swing through the turntable 13 and generate displacement, so that the sliding rod 15 moves up and down. This allows the stirring rod 6 to move up and down while stirring horizontally, which further improves the mixing efficiency. At the same time, the bubbles generated by stirring accelerate the volatilization of free chlorine. Meanwhile, the valve 22 is opened, the fan 20 draws air from the outside, and the airflow is sprayed out through the one-way nozzle 25, generating a large number of bubbles in the material to be dechlorinated, which not only accelerates the volatilization of free chlorine, but also further improves the mixing efficiency of the material to be dechlorinated and the dechlorination agent.
