[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Example 1

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a corrosion and scale inhibitor dosing device, including a mixing shell 1. A feeding mechanism 2 and a control panel 4 are fixedly connected to the outer surface of the mixing shell 1, and a mixing mechanism 3 is rotatably connected to the inner wall of the mixing shell 1. The feeding mechanism 2 includes a fixing plate 201 fixedly connected to the upper surface of the mixing shell 1. A feeding bin 208 is fixedly connected to the outer surface of the fixing plate 201. A conveying frame 211 is fixedly connected to the lower surface of the feeding bin 208. The conveying frame 211 is fixedly connected to the inner wall of the mixing shell 1, and a sliding plate 216 is slidably connected to the inner wall of the conveying frame 211. A weighing sensor 215 is fixedly connected to the upper surface of the sliding plate 216. A weighing platform 214 is fixedly connected to the detection end of the weighing sensor 215. A sealing plate 213 is fixedly connected to the outer surface of the sliding plate 216. The weighing sensor 215 is usually a resistance strain gauge weighing sensor, whose core components are an elastic element and a strain gauge. When the corrosion and scale inhibitor powder is placed on the weighing platform 214, the platform transmits pressure to the elastic element, causing it to deform. The strain gauges attached to the elastic element change resistance as the element deforms. According to the resistance-strain effect, the change in resistance is proportional to the pressure exerted on the elastic element, which in turn is related to the weight of the corrosion and scale inhibitor powder. By measuring the change in strain gauge resistance and performing relevant circuit conversions and calculations, the weight of the corrosion and scale inhibitor powder can be determined.

[0032] The specific feeding mechanism 2 also includes a connecting shaft 204 fixedly connected to the outer surface of the rotating frame 301. A driving bevel gear 203 is fixedly connected to the outer surface of the connecting shaft 204. A driven bevel gear 202 is meshed with the outer surface of the driving bevel gear 203. A spiral blade 209 is fixedly connected to the outer surface of the driven bevel gear 202. The spiral blade 209 is rotatably connected to the inner wall of the feed hopper 208. An electric telescopic rod 210 is fixedly connected to the outer surface of the conveying frame 211. The output end of the electric telescopic rod 210 is fixedly connected to the outer surface of the sealing plate 213. A limiting rod 205 is fixedly connected. A limiting sleeve is fixedly connected to the outer surface of the sealing plate 213 in conjunction with the outer surface of the limiting rod 205. The inner wall of the limiting sleeve is slidably connected to the inner wall of the limiting rod 205. A water flow sensor 207 is fixedly connected to the upper surface of the mixing shell 1. A water inlet pipe 206 is fixedly connected to the inlet of the water flow sensor 207. A rubber plate 212 is fixedly connected to the inner wall of the conveying frame 211. The outer surface of the rubber plate 212 is slidably connected to the outer surface of the weighing platform 214. Both the water flow sensor 207 and the weighing sensor 215 are electrically connected to the control panel 4 through wires.

[0033] Furthermore, the water flow sensor 207 measures the influent flow rate, and the weighing sensor 215 measures the weight of the corrosion and scale inhibitor powder. This allows for precise control of the amount of corrosion and scale inhibitor powder used based on the actual influent flow rate, achieving accurate dosing and ensuring that the mixing ratio of water and corrosion and scale inhibitor meets the requirements, thereby improving the corrosion and scale inhibition effect.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The mixing mechanism 3 includes a rotating frame 301 rotatably connected to the inner wall of the mixing shell 1. A stirring paddle 302 is fixedly connected to the outer surface of the rotating frame 301.

[0036] The specific mixing mechanism 3 also includes a reduction motor 303 fixedly connected to the lower surface of the mixing housing 1. The output shaft of the reduction motor 303 passes through the inner wall of the mixing housing 1 and is fixedly connected to the outer surface of the rotating frame 301. A discharge valve 5 is fixedly connected to the lower surface of the mixing housing 1.

[0037] Furthermore, an anti-clogging mechanism consisting of a driving bevel gear 203, a driven bevel gear 202, and a spiral blade 209 is installed in the feed hopper 208. The spiral blade 209 is driven to rotate by the power of the rotating frame 301, which effectively prevents the corrosion and scale inhibitor powder from clogging in the feed hopper 208, ensuring the continuity and stability of the dosing process and improving work efficiency.

[0038] Working Principle: When using this solid corrosion and scale inhibitor dosing device, first connect the external water pipe to the inlet pipe 206. Water flows into the mixing shell 1 through the inlet pipe 206. The water flow sensor 207 monitors and accurately measures the amount of water injected into the mixing shell 1 in real time. Based on the measured water volume, the required amount of corrosion and scale inhibitor powder can be calculated. Then, start the reduction motor 303, whose output shaft drives the rotating frame 301 to rotate. The stirring paddle 302 on the rotating frame 301 rotates accordingly, fully stirring the water entering the mixing shell 1 and the subsequently added corrosion and scale inhibitor powder to ensure uniform mixing. At the same time, the rotating frame 301 drives the connecting shaft 204 to rotate, which in turn drives the drive bevel gear 203 to rotate. The drive bevel gear 203 meshes with the driven bevel gear 202, causing the driven bevel gear 202 to rotate, which in turn drives the spiral blades 209 in the feed bin 208 to rotate. The rotation of the spiral blades 209 effectively prevents the corrosion and scale inhibitor powder in the feed hopper 208 from clogging, allowing the powder to flow slowly and steadily to the weighing platform 214. The weighing sensor 215 on the weighing platform 214 measures the weight of the powder in real time. When the preset weight is reached, the electric telescopic rod 210 is activated. The output end of the electric telescopic rod 210 pushes the sealing plate 213 to move, causing the sliding plate 216 to slide out from the conveying frame 211. During the sliding of the sliding plate 216, the rubber plate 212 on the inner wall of the conveying frame 211 sweeps the corrosion and scale inhibitor powder on the weighing platform 214 into the mixing shell 1, thus precisely controlling the amount of powder added. If too much corrosion and scale inhibitor powder is found during operation, an appropriate amount of water can be injected into the mixing shell 1 through the water inlet pipe 206 to ensure the accuracy of the mixing ratio.
