It consists of a metering pump, solution tank, control system, piping, and valves mounted on a single base, enabling the dissolution, metering, and dosing of chemicals.

[0003] The existing automatic dosing device technology for circulating water has the following problems: During the use of existing automatic dosing devices for circulating water, uneven mixing is prone to occur when mixing multiple agents. In addition, the agents are often accompanied by dregs, and the accumulation of these dregs can easily cause pipe blockage and affect the dosing process. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-4 As shown, this utility model provides an automatic dosing device for circulating water, including a mixing tank 1, a PLC controller 2, a drive motor 3, and a medicine tank 4. The drive motor 3 is fixedly connected to the top of the mixing tank 1 via a bracket. A stirring cylinder 10 is rotatably connected to the top of the inner wall of the mixing tank 1, and a stirring rod 12 is rotatably connected to the inner wall of the stirring cylinder 10. The drive motor 3 drives the stirring cylinder 10 and the stirring rod 12 to rotate in opposite directions via a linkage assembly 9 located at the top of the mixing tank 1.

[0027] The linkage assembly 9 includes gear 14, gear 2 15 and gear 3 16. The top end of gear 14 is fixedly connected to the bottom end of drive motor 3. Gear 14 meshes with gear 2 15, gear 2 15 meshes with gear 3 16, and a pulley 17 is fixedly connected to the top end of gear 3 16. The outer wall of pulley 17 is connected to the top end of stirring rod 12 via a belt. The bottom end of gear 2 15 is fixedly connected to the top end of stirring drum 10.

[0028] The drive motor 3 drives gear 14 to rotate, which in turn drives gear 2 15 to rotate. Gear 2 15 drives the mixing drum 10 to rotate, stirring the contents of the mixing tank 1. At the same time, gear 2 15 drives gear 3 16 to rotate in the opposite direction. Gear 3 16 drives the stirring rod 12 to rotate through pulley 17. At this time, the direction of rotation of the stirring rod 12 is opposite to that of the mixing drum 10.

[0029] The stirring drum 10 and the stirring rod 12 form opposite stirring directions, which improves the mixing efficiency of the circulating water and the medicine inside the mixing tank 1, so that the medicine and the circulating water are fully mixed.

[0030] A conical filter screen 11 is installed below the mixing drum 10. The inner wall of the conical filter screen 11 is rotatably connected to the outer wall of the mixing rod 12. An agitating scraper 13 is fixedly connected to the outer wall of the mixing rod 12. The top of the mixing rod 12 extends movably through to the top of the gear 15. Solenoid valves are installed on the outer walls of both the water inlet pipe 8 and the slag discharge pipe 7.

[0031] The outer wall of the cone-shaped filter screen 11 is movably connected to the bottom surface of the agitator scraper 13.

[0032] Both the outer walls of the mixing drum 10 and the mixing rod 12 are fixedly connected with mixing teeth.

[0033] Example 2

[0034] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the bottom end of the medicine box 4 is fixedly connected to the top end of the mixing tank 1 through the medicine drain pipe 5, and the bottom end of the mixing tank 1 is fixedly connected to the drain pipe 6.

[0035] Solenoid valves are installed on the outer walls of both the medicine supply pipe 5 and the drain pipe 6.

[0036] A slag discharge pipe 7 is fixedly connected to the side of the mixing tank 1 near the bottom, and a water inlet pipe 8 is fixedly connected to the side of the mixing tank 1 near the top.

[0037] The bottom ends of gear 14 and gear 36 are rotatably connected to the top of mixing tank 1.

[0038] The working principle of this automatic dosing device for circulating water will be explained in detail below.

[0039] like Figure 1-4 As shown, during use, the solenoid valve on the medicine pipe 5 is opened by the PLC controller 2, and a certain amount of medicine solution is added to the mixing tank 1. Then, a suitable amount of circulating water is delivered to the mixing tank 1 through the water inlet pipe 8. Then, the drive motor 3 is started. At this time, the drive motor 3 drives the gear 14 to rotate, and the gear 14 drives the gear 2 15 to rotate. The gear 2 15 drives the stirring drum 10 to rotate, stirring the inside of the mixing tank 1. At the same time, the gear 2 15 drives the gear 3 16 to rotate in the opposite direction. The gear 3 16 drives the stirring rod 12 to rotate through the pulley 17. At this time, the rotation direction of the stirring rod 12 is opposite to that of the stirring drum 10.

[0040] The stirring drum 10 and the stirring rod 12 form opposite stirring directions, which improves the mixing efficiency of the circulating water and the medicine inside the mixing tank 1, so that the medicine and the circulating water are fully mixed.

[0041] Once the mixture in mixing tank 1 is fully mixed, drain pipe 6 is opened to discharge the liquid from mixing tank 1. Meanwhile, impurities filtered by the conical filter screen 11 are quickly discharged through the slag discharge pipe 7, aided by the scraping action of the stirring scraper 13. Furthermore, the scraping action of the stirring scraper 13 prevents clogging of the sieve holes on the conical filter screen 11, ensuring its filtration efficiency.

[0042] It should be noted that the terms "comprising," "including," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The present invention has been described in detail above, but modifications or improvements can be made based on it, which will be apparent to those skilled in the art. Therefore, modifications or improvements that do not depart from the spirit and intent of the present invention are within the scope of protection of the present invention.
