[0002] Water treatment equipment removes harmful substances from water using physical, chemical, and biological methods. It involves sedimentation, filtration, coagulation, flocculation, and water quality conditioning such as corrosion inhibition and scale inhibition to suit specific applications. Existing water treatment equipment is prone to scaling, has a short lifespan, and increases costs and consumption.

[0003] The utility model patent with publication number CN208265860U provides a device for adding corrosion and scale inhibitors for circulating water treatment. The device uses a stepper motor to drive a circular flap to flip, which opens the guide tube to facilitate the addition of the additive. It is easy to operate and saves time and effort.

[0004] However, due to the different flow rates of the incoming sewage, the required dosage also varies. Directly flipping the container to remove the obstruction makes it difficult to accurately control the dosage, which can easily lead to situations where the dosage is too low or too high, resulting in waste and affecting the treatment process. Utility Model Content

[0006] To achieve the above objectives, this utility model provides a precise scale inhibitor dosing device for water treatment, comprising a scale inhibitor dosing assembly and a mixing tank with an inlet pipe and an outlet pipe respectively arranged on both sides; the scale inhibitor dosing assembly includes a scale inhibitor storage tank, a discharge pipe, a scale ruler, a feed pipe, and a movable baffle. The scale inhibitor storage tank is fixedly installed on the top of the mixing tank, the discharge pipe is fixedly connected to and communicates with the scale inhibitor storage tank, the discharge pipe is located below the scale inhibitor storage tank, the scale ruler is arranged on the side of the discharge pipe, the movable baffle is movably arranged below the discharge pipe, the feed pipe is fixedly connected to and communicates with the mixing tank, the feed pipe is located on the top of the mixing tank, and the feed pipe is located directly below the discharge pipe.

[0007] The scale inhibitor dosing assembly further includes a mounting bracket and an adjusting screw. The mounting bracket is fixedly connected to the scale inhibitor storage tank and is spaced apart on the side of the discharge pipe. The adjusting screw is threadedly connected to the mounting bracket and passes through the mounting bracket. One end of the adjusting screw is rotatably connected to the movable baffle and is located on the side of the movable baffle.

[0008] The scale inhibitor dosing assembly further includes a rotating rod, which is fixedly connected to the adjusting screw, and the rotating rod is located at the end of the adjusting screw away from the movable baffle.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a water treatment scale inhibitor precise dosing device according to the present invention. Figure 2 This is a structural cross-sectional view of a water treatment scale inhibitor precise dosing device according to this utility model. Figure 3 This is the utility model Figure 2 A magnified view of a portion of point A in the middle.

[0019] This utility model provides a precise dosing device for water treatment scale inhibitor, including a scale inhibitor dosing component, a stirring component, and a mixing tank 100 with an inlet pipe and an outlet pipe on both sides. The scale inhibitor dosing component includes a scale inhibitor storage tank 210, a discharge pipe 220, a scale ruler 230, a feed pipe 240, a movable baffle 250, a mounting bracket 260, an adjusting screw 270, and a rotating rod 280. The stirring component includes a rotating shaft 310, a connecting rod 320, and stirring blades 330.

[0020] In this specific embodiment, the scale inhibitor storage tank 210 is fixedly installed on the top of the mixing tank 100. The discharge pipe 220 is fixedly connected to and communicates with the scale inhibitor storage tank 210, and is located below the scale inhibitor storage tank 210. The scale ruler 230 is disposed on the side of the discharge pipe 220. The movable baffle 250 is movably disposed below the discharge pipe 220. The feed pipe 240 is fixedly connected to and communicates with the mixing tank 100, and is located on the top of the mixing tank 100, and is located directly below the discharge pipe 220. Water inlet pipes and water outlet pipes are provided on both sides of the mixing tank 100. A flow meter is installed on the water inlet pipe to monitor the water inflow rate into the mixing tank 100. The mixture of water and scale inhibitor in the mixing tank 100 flows out through the water outlet pipe. The movable baffle 250 is fitted below the discharge pipe 220. The scale inhibitor storage tank 210 is used to store the scale inhibitor, which can be discharged through the discharge pipe 220. The discharge port of the discharge pipe 220 is square. The cross-sectional area of ​​the movable baffle 250 is larger than that of the discharge pipe 220, so that the movable baffle 250 can completely block the discharge pipe 220. A scale 230 is provided above the movable baffle 250. When the movable baffle 250 slides below the discharge pipe 220, the volume blocked by the movable baffle 250 can be calculated using the scale 230, and then the unblocked volume can be calculated to accurately obtain the discharge rate of the scale inhibitor. This allows for adjustment of the discharge rate of the scale inhibitor according to the water flow rate, and precise adjustment of the dosage of the scale inhibitor to prevent over- or under-dosing. After the position of the movable baffle 250 below the discharge pipe 220 is adjusted, the scale inhibitor flows out through the discharge pipe 220 and into the mixing tank 100 through the feed pipe 240.

[0021] Furthermore, the mounting bracket 260 is fixedly connected to the scale inhibitor storage tank 210. The mounting bracket 260 is spaced apart on the side of the discharge pipe 220. The adjusting screw 270 is threadedly connected to the mounting bracket 260. The adjusting screw 270 passes through the mounting bracket 260, and one end of the adjusting screw 270 is rotatably connected to the movable baffle 250. The adjusting screw 270 is located on the side of the movable baffle 250. The mounting bracket 260 is used to mount the adjusting screw 270. The adjusting screw 270 can rotate relative to the mounting bracket 260. When the adjusting screw 270 rotates, the length of the adjusting screw 270 on both sides of the mounting bracket 260 will change, thereby allowing the movable baffle 250 to move left and right under the action of the adjusting screw 270 to adjust the dosage of the scale inhibitor.

[0022] Specifically, the rotating rod 280 is fixedly connected to the adjusting screw 270, and the rotating rod 280 is located at the end of the adjusting screw 270 away from the movable baffle 250. The rotating rod 280 is provided at the end of the adjusting screw 270 so that the operator can rotate the adjusting screw 270 by means of the rotating rod 280.

[0023] The rotating shaft 310 is rotatably disposed inside the mixing tank 100. Multiple connecting rods 320 are spaced apart on the outer side of the rotating shaft 310, and multiple stirring blades 330 are spaced apart on each connecting rod 320. The stirring assembly is used to stir the water and scale inhibitor in the mixing tank 100. The rotating shaft 310 is driven by a motor, and the multiple stirring blades 330 are mounted on the connecting rods 320. The connecting rods 320 and the stirring blades 330 can stir the water and scale inhibitor.

[0024] In addition, the stirring blade 330 is provided with a threaded sleeve 331, and the connecting rod 320 is provided with a threaded post 321 that is adapted to the threaded sleeve 331. The threaded post 321 is threadedly connected to the threaded sleeve 331. The threaded sleeve 331 and the threaded post 321 cooperate with each other to connect the stirring blade 330 and the connecting rod 320.

[0025] When using a water treatment scale inhibitor precise dosing device, the water flow rate is determined by a flow meter on the inlet pipe, and the required dosage of scale inhibitor is calculated. Then, the adjusting screw 270 is rotated to push the movable baffle 250 to slide below the discharge pipe 220. The volume blocked by the movable baffle 250 on the discharge pipe 220 is calculated by the scale 230, and the unblocked volume is calculated to accurately obtain the scale inhibitor discharge rate. This allows for adjustment of the scale inhibitor discharge rate according to the water flow rate, thereby precisely adjusting the dosage of scale inhibitor to prevent over- or under-dosing.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
