[0024] The present invention will be further described in detail below with reference to embodiments:
[0025] like Figures 1-5 As shown, this utility model provides a high-hardness leachate concentrate coagulation device, including a base 1, a high-efficiency reaction mechanism 2 is provided on the top of the base 1, and a convenient dosing mechanism 3 is provided on the base 1 and the high-efficiency reaction mechanism 2.
[0026] The high-efficiency reaction mechanism 2 includes a coagulation tank 22. A support frame 24 is fixedly installed on the top of the coagulation tank 22. A variable frequency speed control motor 25 is fixedly installed on the top of the support frame 24. A rotating shaft 26 is rotatably connected to the bottom of the support frame 24. The output shaft of the variable frequency speed control motor 25 is fixedly connected to the top of the rotating shaft 26. A first stirring blade 261 is fixedly installed on the outer wall of the rotating shaft 26. An extension shaft 262 is fixedly installed at the bottom of the rotating shaft 26. A second stirring blade 263 is fixedly installed at the bottom of the extension shaft 262. In the concentrate and... After the chemical reagents are added to the inside of the coagulation tank 22, the variable frequency speed control motor 25 is controlled to work, driving the rotating shaft 26 to rotate at the bottom of the support frame 24, thereby driving the first stirring paddle 261 and the second stirring paddle 263 to rotate, mixing the liquid inside the coagulation tank 22, promoting full and rapid fusion between the concentrate and the chemical reagents, shortening the time required for full reaction, and improving efficiency. The second stirring paddle 263 can effectively stir the solution at the bottom of the inner cavity of the coagulation tank 22, improving the mixing effect.
[0027] Furthermore, such as Figure 2As shown, a connecting leg 27 is detachably connected to the outer wall of the rotating shaft 26. A hollow support rod 28 is fixedly installed at the end of the connecting leg 27 away from the rotating shaft 26. The connecting leg 27 is installed on the outer wall of the rotating shaft 26 with screws, and the connecting leg 27 and the hollow support rod 28 can be disassembled and maintained as a whole.
[0028] Furthermore, such as Figure 2 As shown, a slider 281 is slidably connected to the inner wall of the hollow support rod 28. An elastic element 282 is fixedly installed on one side of the slider 281. The end of the elastic element 282 away from the slider 281 is fixedly installed on the inner wall of the hollow support rod 28. A connecting support rod 283 is fixedly installed on the side of the slider 281 away from the elastic element 282. A clamping bolt 284 is threadedly connected to the outer wall of the connecting support rod 283. A scraping rod 29 is movably inserted into the inner cavity of the connecting support rod 283. The threaded end of the clamping bolt 284 movably abuts against the outer wall of the scraping rod 29. The variable frequency speed control motor 25 drives the first stirring paddle 261 and the second stirring paddle 26. 3. During the stirring process, the variable frequency speed control motor 25 drives the rotating shaft 26 to rotate at a slow speed. After a period of use, impurities may adhere to the inner wall of the coagulation tank 22, requiring cleaning. After the solution in the inner cavity of the coagulation tank 22 is discharged, the variable frequency speed control motor 25 drives the rotating shaft 26 to rotate rapidly. At this time, the centrifugal force on the scraper rod 29 will increase. This larger centrifugal force will pull the slider 281, causing the slider 281 to break free from the elastic force of the elastic element 282 and slide on the inner wall of the hollow support rod 28, so that the scraper rod 29 is tightly attached to the inner wall of the coagulation tank 22. With rotation, the inner wall of the coagulation tank 22 can be scraped and cleaned, facilitating efficient cleaning. When the variable frequency speed-regulating motor 25 drives the rotating shaft 26 to rotate slowly or remain stationary, the elastic force of the elastic element 282 can pull the slider 281, preventing the scraper rod 29 from contacting the inner wall of the coagulation tank 22 and avoiding continuous wear. During maintenance, the scraper rod 29 can be replaced by loosening the clamping bolt 284. It is worth noting that the variable frequency speed-regulating motor 25 in this solution is a commercially available device that can be purchased by those skilled in the art. No structural improvements have been made in this paper. Therefore, those skilled in the art are familiar with its working principle based on their professional knowledge and can apply it proficiently. Thus, this paper will not elaborate on it further. At the same time, this solution aims to protect the physical structure, but does not protect the circuit and software control. The proposed processing circuit in this paper is only to supplement the explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuit technology. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.
[0029] Furthermore, such as Figure 1 As shown, a support sleeve 21 is fixedly installed on the outer wall of the coagulation tank 22. The support sleeve 21 is fixedly installed on the top of the base 1. A discharge valve 23 is fixedly connected to the bottom of the coagulation tank 22. The support sleeve 21 is used to support the coagulation tank 22 and control the discharge valve 23 to open, so that the treated sediment and liquid inside the coagulation tank 22 can be discharged one by one.
[0030] Furthermore, such as Figure 4 As shown, the convenient dosing mechanism 3 includes an annular pipe 31, which is fixedly installed on the inner wall of the coagulation tank 22. An output hole 32 is provided on the inner surface of the annular pipe 31. Chemical agents can be input into the inner cavity of the annular pipe 31 and then uniformly delivered to the inner cavity of the coagulation tank 22 from the output hole 32.
[0031] Furthermore, such as Figure 4 As shown, the convenient dosing mechanism 3 also includes a base plate 34, which is fixedly installed on the top of the base 1. A pump 35 is fixedly installed on the bottom of the base plate 34. The input end of the pump 35 is fixedly connected to the bottom of the base plate 34, and the output end of the pump 35 is fixedly connected to a connecting pipe 33. The end of the connecting pipe 33 away from the pump 35 is fixedly connected to the top of the annular pipe 31. By controlling the operation of the pump 35, the chemical agent above the base plate 34 can be drawn and then transported through the connecting pipe 33 into the inner cavity of the annular pipe 31.
[0032] Furthermore, such as Figure 5 As shown, a transparent temporary storage tank 36 is fixedly installed on the top of the base plate 34. The outer wall of the transparent temporary storage tank 36 is coated with scale lines 361. When in use, chemical agents can be added to the inner cavity of the transparent temporary storage tank 36. The design of the scale lines 361 makes it easy for users to design the amount to be added.
[0033] Furthermore, such as Figure 5 As shown, a protrusion 362 is fixedly installed on the outer wall of the transparent storage tank 36, and a rotating arm 363 is rotatably connected to the inner wall of the protrusion 362. A cover plate 364 is fixedly installed at the end of the rotating arm 363, and a handle 365 is fixedly installed on the top of the cover plate 364. Through the design of the protrusion 362 and the rotating arm 363, the user can rotate the cover plate 364 to open and close it from the top of the transparent storage tank 36. When not in use, the cover plate 364 can be placed on the top of the transparent storage tank 36 for dust protection.
[0034] The working principle of this high-hardness leachate concentrate coagulation device will be explained in detail below.
[0035] like Figures 1-5As shown, during use, the concentrate is first poured into the inner cavity of the coagulation tank 22. Chemical agents can be added into the inner cavity of the transparent temporary storage tank 36. The pump 35 is controlled to operate, which can extract the chemical agents above the bottom plate 34 and then transport them through the connecting pipe 33 to the inner cavity of the annular pipe 31. Then, it is evenly transported into the inner cavity of the coagulation tank 22 from the output hole 32. After the concentrate and chemical agents are added into the coagulation tank 22, the variable frequency speed control motor 25 can be controlled to operate, driving the rotating shaft 26 to rotate, which in turn drives the first stirring paddle 261 and the second stirring paddle 263 to rotate, mixing the liquid inside the coagulation tank 22 and promoting the full and rapid fusion between the concentrate and the chemical agents. After the reaction is completed, the discharge valve 23 is controlled to open, and the treated sediment and liquid inside the coagulation tank 22 can be discharged one by one.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
