[0019] In order to make the personnel in the technical field better understand the utility model scheme, the technical scheme in the utility model embodiment will be clearly and completely described below, obviously, the described embodiment is only a part of the embodiment of the utility model, not all. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor should belong to the scope of the utility model protection.
[0020] As shown in the accompanying Figures 1-5 .
[0021] A water treatment dosing device includes a support frame 1, a mixing tank 2 installed below the support frame 1, a feeding hopper 21 at the top of the mixing tank 2, a stirring rod 3 inside the mixing tank 2, the upper end of the stirring rod 3 being connected to a stirring motor 4 installed above the support frame 1, and an upper stirring blade 31 located in the middle section of the stirring rod 3 inside the mixing tank 2. In use, different agents are added to the mixing tank 2 through the feeding hopper 21, and the stirring motor 4 drives the stirring rod 3 to rotate. The upper stirring blade 31 enables the agents to be uniformly mixed in the mixing tank 2.
[0022] A guide tube 5 is provided below the mixing tank 2, and a valve 7 is provided at the connection between the mixing tank 2 and the guide tube 5. A flow divider 6 is provided in the stirring rod 3 and below the guide tube 5, and a lower stirring blade 32 is provided in the stirring rod 3 and below the flow divider 6. Based on the above structure, after the agent in the mixing tank 2 is stirred, the valve 7 is opened, and the agent flows down through the guide tube 5. After passing through the flow divider 6, the flowing agent can be evenly dispersed to the surrounding area, avoiding the accumulation of agent in the center of the lower stirring blade 32. Under the action of the lower stirring blade 32, the agent is further evenly mixed in the water tank, improving the water treatment efficiency.
[0023] The valve 7 described above includes a gate body, a baffle 71, a push plate 72, and a bidirectional telescopic rod 73, wherein the baffle 71 is as shown in the attached figure. Figure 5 As shown, there are two of them, each with a C-shaped structure. The two baffles 71 are installed opposite each other inside the gate body to form an annular baffle that can block the flow guide tube 5. The stirring rod 3 passes between the two baffles 71. When the valve 7 is closed, the inner side of the baffle 71 is tightly fitted with the outer wall of the stirring rod 3. Without affecting the rotation of the stirring rod 3, it can also prevent the agent from leaking from the contact position between the stirring rod 3 and the baffle 71.
[0024] Each baffle 71 is connected to the push plate 72 below the valve 7 via a connecting rod at its lower end. A bidirectional telescopic rod 73 is provided on each side below the valve 7. The bidirectional telescopic rod 73 is connected to the push plate 72 on both sides. A moving groove 74 for the movement of the connecting rod is provided below the gate body. The two bidirectional telescopic rods 73 extend and retract synchronously, driving the push plate 72 on both sides to move, thereby opening and closing the baffle 71 and controlling the flow of the guide tube 5.
[0025] The procedure for using this device is as follows: Install the device in the water tank, ensuring that valve 7 is above the water surface during installation, and ensuring that valve 7 can be opened and closed normally.
[0026] When it is necessary to add the agent into the water tank, add it into the mixing tank 2 through the feeding hopper 21. At this time, the valve 7 is in the closed state. Start the stirring motor 4. The agent begins to mix under the action of the stirring blade 31 in the mixing tank 2. During the mixing process, add an appropriate amount of water to slightly dilute the agent and ensure that the agent is fully dissolved.
[0027] After the medicament is mixed, the valve 7 is opened, the medicament is uniformly dispersed to the pool through the guide cylinder 5 and the distribution plate 6, and under the pushing of the lower stirring blade 32, the medicament is further diffused in the pool, so that the medicament is fully mixed with the sewage in the pool, thereby improving the water quality treatment effect.
[0028] The technical scheme disclosed by the utility model, or the technical scheme designed by the person skilled in the art inspired by the technical scheme of the utility model, similar technical schemes achieving the above technical effects are all within the protection scope of the utility model.
