Detailed implementation manners

[0028] As Figures 1-7 shown, a water treatment chemical dosing device for a heat supply pipe network includes a medicine barrel 1. A discharge valve seat 8 is arranged on the lower surface of the medicine barrel 1. A lifting unit 4 is arranged on the side surface of the medicine barrel 1. The lifting unit 4 is connected with a cover plate 2. The cover plate 2 is located directly above the medicine barrel 1. A feeding pipe 6, a controller 7 and a stirring unit are installed on the cover plate 2. A filter cartridge 5 is installed on the lower surface of the cover plate 2. The filter cartridge 5 is communicated with the feeding pipe 6. The controller 7 is electrically connected with an external power supply. The controller 7 operates using existing technologies. The discharge valve seat 8 is connected with a heat supply pipe, as Figure 1 , Figure 6 , Figure 7As shown in the figure, the cover plate 2 is used to close or open the medicine barrel 1 through the lifting unit 4. The medicine is added into the medicine barrel 1 through the feeding pipe 6. The added medicine is filtered and screened through the filter cartridge 5 to prevent the medicine from caking and affecting the mixing speed. The medicine and hot water in the medicine barrel 1 are stirred and mixed through the stirring unit, so that the medicine and hot water are quickly mixed. The mixed medicine is exported into the hot water pipe through the discharge valve seat 8;

[0029] The stirring unit on the cover plate 2 includes a motor 31 and a main shaft 32. The motor 31 is arranged on the cover plate 2. The main shaft 32 is rotatably installed on the cover plate 2 and the filter cartridge 5. The main shaft 32 is connected to the output shaft of the motor 31. A crushing component is arranged on the part of the main shaft 32 located inside the filter cartridge 5. An installation seat 36 and a second material lifting plate 35 are arranged on the part of the main shaft 32 located inside the medicine barrel 1. The second material lifting plate 35 is slidably connected to the inner bottom surface of the medicine barrel 1. The installation seat 36 is located between the second material lifting plate 35 and the filter cartridge 5. A rotating shaft 37 is rotatably installed on the installation seat 36. A support rod 38 is vertically installed on the rotating shaft 37. An end part of the support rod 38 is provided with a movable component. A stirring rod 311 is installed on the movable component. A transmission component is installed at the end part of the rotating shaft 37. A roller 316 is installed on the transmission component. The roller 316 is in rolling connection with the inner wall of the medicine barrel 1. The motor 31 is electrically connected to the controller 7. The operation of the motor 31 adopts the existing technology, such as Figure 1 、 Figure 6 、 Figure 7 As shown in the figure, the motor 31 drives the main shaft 32 to rotate. The main shaft 32 drives the crushing component, the installation seat 36 and the second material lifting plate 35 to rotate. The crushing component crushes the medicine in the filter cartridge 5 to prevent the medicine from caking and affecting the mixing efficiency. The second material lifting plate 35 scrapes and lifts the medicine at the bottom of the medicine barrel 1 to avoid the medicine precipitating in the medicine barrel 1 and affecting the mixing efficiency and effect, ensuring the full mixing of the medicine and hot water, such as Figures 1-3 As shown in the figure, when the main shaft 32 rotates, the rotating shaft 37 is driven to rotate through the installation seat 36. The rotating shaft 37 drives the support rod 38, the stirring rod 311 and the rotating roller 316 to rotate along the circumferential direction of the medicine barrel 1. The medicine and hot water in the medicine barrel 1 are stirred and mixed by the rotating shaft 37, the support rod 38 and the stirring rod 311. At the same time, when the roller 316 rotates along the medicine barrel 1, the roller 316 rotates itself. The roller 316 makes the rotating shaft 37 rotate itself through the transmission component. The rotating shaft 37 drives the support rod 38 and the stirring rod 311 to rotate themselves. At the same time, the stirring rod 311 and the support rod 38 are movably connected through the movable component. During the rotation of the support rod 38 and the stirring rod 311, the placement angle of the stirring rod 311 changes, so that the rotating shaft 37, the support rod 38 and the stirring rod 311 stir the medicine and hot water at multiple angles, making the medicine and hot water quickly and fully mixed, effectively improving the mixing efficiency and effect.

[0030] The movable assembly at the end of the support rod 38 includes a movable seat 39 and a torsion spring 310. The movable seat 39 is rotatably installed at the end of the support rod 38. The movable seat 39 is connected to the stirring rod 311. A torsion spring 310 is sleeved on the part where the movable seat 39 and the support rod 38 are rotatably connected. The two ends of the torsion spring 310 are respectively connected to the movable seat 39 and the support rod 38. As Figure 3 shown, through the torsion spring 310 and the movable seat 39, the stirring rod 311 is rotatably connected to the support rod 38. When the support rod 38 drives the stirring rod 311 to rotate through the movable seat 39, the stirring rod 311 is forced to drive the movable seat 39 to rotate by a certain angle, so that the position and inclination angle of the stirring rod 311 change. Due to the existence of the torsion spring 310, when the stirring rod 311 drives the movable seat 39 to rotate, the torsion spring 310 exerts forces in opposite directions on the stirring rod 311 and the movable seat 39, causing the stirring rod 311 and the movable seat 39 to rotate back and forth, so that the stirring rod 311 stirs and mixes the medicament and hot water at multiple angles, effectively improving the mixing efficiency and effect.

[0031] The transmission assembly on the rotating shaft 37 includes an installation box 312. The installation box 312 is rotatably installed on the rotating shaft 37. A limiting mechanism is provided on the installation box 312. A support shaft 315 is rotatably installed on the installation box 312. The support shaft 315 is connected to a roller 316. The end of the rotating shaft 37 located inside the installation box 312 is connected to a first bevel gear 313. The part of the support shaft 315 located inside the installation box 312 is connected to a second bevel gear 314. The second bevel gear 314 is meshed with the first bevel gear 313. As Figure 1 、 Figure 2 、 Figure 5 shown, when the installation box 312 rotates in the medicine barrel 1, the installation box 312 is limited by the limiting mechanism, effectively preventing the installation box 312 from rotating on its own. When stirring and mixing the medicament and hot water in the medicine barrel 1, the roller 316 rotates while moving along the inner wall of the medicine barrel 1. The roller 316 drives the support shaft 315 to rotate, the support shaft 315 drives the second bevel gear 314 to rotate, the second bevel gear 314 drives the first bevel gear 313 to rotate, and the first bevel gear 313 drives the rotating shaft 37 to rotate, so that the rotating shaft 37 rotates on its own, enabling the rotating shaft 37 to better stir and mix the medicament and hot water.

[0032] The crushing assembly on the main shaft 32 includes a crushing knife 33 and a first material lifting plate 34. Both the crushing knife 33 and the first material lifting plate 34 are located on the part of the main shaft 32 inside the filter cylinder 5. The first material lifting plate 34 is slidably connected to the inner bottom surface of the filter cylinder 5. As Figure 1 、 Figure 4As shown, after the medicament enters the filter cartridge 5, the main shaft 32 drives the first material lifting plate 34 and the crushing knife 33 to rotate. The crushing knife 33 crushes the medicament in the filter cartridge 5, effectively preventing the medicament from caking and affecting the mixing of the medicament and hot water. At the same time, the first material lifting plate 34 pushes and lifts the medicament in the filter cartridge 5, so that the crushing knife 33 can fully crush the medicament, ensuring the uniformity of the medicament and enabling the medicament to mix better with hot water.

[0033] The limiting mechanisms on both sides of the installation box 312 include support arms 9 and scraping plates 10. The support arms 9 are installed on both sides of the installation box 312. The support arms 9 are connected to the scraping plates 10, and the scraping plates 10 are slidably connected to the inner wall of the medicine barrel 1. As Figure 1 、 Figure 2 shown, the installation box 312 on the rotating shaft 37 is connected through the support arms 9 and the scraping plates 10, thereby realizing the limitation of the installation box 312, effectively preventing the installation box 312 from rotating, improving the stability of the installation box 312. The installation box 312 drives the scraping plates 10 to move along the inner wall of the medicine barrel 1 through the support arms 9, and the scraping plates 10 scrape the medicament on the inner wall of the medicine barrel 1 to prevent the medicament from adhering to the inner wall of the medicine barrel 1 and forming residues, ensuring the uniformity of the medicament mixing.

[0034] The lifting unit 4 on the medicine barrel 1 includes a hydraulic cylinder 41 and a fixing plate 42. The hydraulic cylinder 41 is arranged on the outer surface of the medicine barrel 1, and the fixing plate 42 is arranged on the outer surface of the cover plate 2. The fixing plate 42 is connected to the telescopic end of the hydraulic cylinder 41. The hydraulic cylinder 41 is electrically connected to the controller 7. The operation of the hydraulic cylinder 41 adopts the existing technology. As Figure 6 、 Figure 7 shown, the hydraulic cylinder 41 drives the cover plate 2 to move through the fixing plate 42, and the cover plate 2 closes or opens the medicine barrel 1, improving the convenience during operation and facilitating the inspection and cleaning of the inside of the medicine barrel 1.

[0035] An observation window 11 is arranged on the side of the medicine barrel 1, and a transparent plate 12 is installed in the observation window 11. As Figure 6 shown, when mixing the medicament and hot water in the medicine barrel 1, it is convenient to observe the inside of the medicine barrel 1 through the observation window 11 and the transparent plate 12, so as to check the drug precipitation situation on the bottom surface inside the medicine barrel 1 and ensure the uniformity of the mixing.

[0036] Working principle: Add hot water into the medicine barrel 1. As Figure 6 、 Figure 7 shown, the hydraulic cylinder 41 drives the cover plate 2 to close the medicine barrel 1 through the fixing plate 42; as Figure 1 、 Figure 6 、 Figure 7As shown, the medicament is added into the filter cartridge 5 through the feeding pipe 6, and the medicament is filtered and screened by the filter cartridge 5. The medicament with appropriate particle size enters the medicine barrel 1 through the filter cartridge 5, and the caked medicament remains in the filter cartridge 5;

[0037] As Figure 1 , Figure 6 , Figure 7 shown, the main shaft 32 is driven to rotate by the motor 31, and the first material lifting plate 34, the crushing knife 33, the mounting seat 36 and the second material lifting plate 35 are driven to rotate by the main shaft 32. As Figure 4 shown, the medicament in the filter cartridge 5 is pushed and lifted by the first material lifting plate 34, and the medicament is fully broken by the crushing knife 33. The broken medicament enters the medicine barrel 1;

[0038] Meanwhile, as Figure 1 shown, the medicament at the bottom of the medicine barrel 1 is scraped and lifted by the second material lifting plate 35. As Figures 1-3 shown, the mounting seat 36 drives the rotating shaft 37 to rotate, and the rotating shaft 37 drives the support rod 38, the stirring rod 311, the mounting box 312 and the rotating roller 316 to rotate along the circumferential direction of the medicine barrel 1. The medicament and hot water in the medicine barrel 1 are stirred and mixed by the rotating shaft 37, the support rod 38 and the stirring rod 311. As Figure 6 shown, during the mixing process, the inside of the medicine barrel 1 can be conveniently observed through the observation window 11 and the transparent plate 12;

[0039] When the mounting box 312 rotates, as Figure 1 , Figure 2 shown, the mounting box 312 on the rotating shaft 37 is connected and limited by the support arm 9 and the scraper 10 to prevent the mounting box 312 from rotating. The medicament on the inner wall of the medicine barrel 1 is scraped by the scraper 10 to prevent the medicament from adhering to the inner wall of the medicine barrel 1 and forming residues;

[0040] As Figure 2 , Figure 5 shown, when the roller 316 rotates along the medicine barrel 1, the roller 316 rotates itself. The roller 316 drives the support shaft 315 to rotate, the support shaft 315 drives the second bevel gear 314 to rotate, the second bevel gear 314 drives the first bevel gear 313 to rotate, and the first bevel gear 313 drives the rotating shaft 37 to rotate, so that the rotating shaft 37 rotates itself. The support rod 38 and the stirring rod 311 are driven to rotate by the rotating shaft 37;

[0041] Meanwhile, during the rotation of the stirring rod 311 driven by the support rod 38 through the movable seat 39, the stirring rod 311 drives the movable seat 39 to rotate by a certain angle under force. Due to the existence of the torsion spring 310, when the stirring rod 311 drives the movable seat 39 to rotate, the torsion spring 310 exerts forces in opposite directions on the stirring rod 311 and the movable seat 39, causing the stirring rod 311 and the movable seat 39 to rotate reciprocally;

[0042] As Figure 1 , Figure 3 shown, the rotation of the rotating shaft 37, the support rod 38, and the stirring rod 311 driven by the main shaft 32, together with the self-rotation of the rotating shaft 37, the support rod 38, and the stirring rod 311, enables the rotating shaft 37, the support rod 38, and the stirring rod 311 to stir the medicament and hot water from multiple angles, allowing the medicament and hot water to be quickly and fully mixed. The mixed medicament is then discharged through the discharge valve seat 8 into the hot water pipe.

[0043] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all these changes and improvements fall within the scope of the present invention claimed.
