When the stirring equipment of the existing reactor starts stirring, the resistance is large, which makes the motor load large and easily causes damage to the motor. In addition, the subsequent separation process of the ash water scale inhibitor dispersant is also very cumbersome and not convenient enough. Summary of the invention

[0004] The object of the present invention is to provide a real-time pH monitoring device for the preparation of ash water scale inhibitors and dispersants, so as to solve the problem that the reaction in the preparation process of the existing ash water scale inhibitors and dispersants proposed in the above background technology is not thorough enough, which easily leads to waste of raw materials, not only resulting in a low utilization rate of raw materials, but also a low yield rate of products, thereby increasing the production cost of users.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] When the user uses the device, the user adds the raw materials into the raw material tank, and adds the raw materials into the reaction tank according to the set ratio through the first water pump, the raw material pipeline and the proportioning box. The user adds the set clean water and gas into the reaction tank through the air pipe and the water pipe. The pressure inside the reaction tank can be monitored by the pressure sensor. At the same time, the user controls the heating plate and the heating rod to work. When the inside of the reaction tank reaches the set raw materials, the mixing motor works. The output end of the mixing motor drives the first rotating rod to rotate, and the first rotating rod drives the bottom stirring rod, the movable stirring rod and the mixing plate to rotate. The raw materials at the bottom of the reaction tank can be stirred through the bottom stirring rod. Since the mixing plate and the movable stirring rod are close to the first rotating rod, the mixing motor drives the first rotating rod When the mixing plate rotates, no too large load is required, which facilitates the starting of the mixing motor and reduces damage to the mixing motor. When the mixing motor drives the first rotating rod and the mixing plate to rotate faster and faster, the mixing plate moves to the side away from the first rotating rod under the action of centrifugal force, and the mixing plate drives the movable stirring rod to slide inside the sliding hole. At the same time, the movable stirring rod drives the first slider to slide inside the first sliding groove and the second sliding groove. The movable stirring rod can stretch and compress the first spring while moving until the first slider contacts one end of the first rotating rod and the second sliding groove. At this time, the mixing plate no longer moves to the side away from the first rotating rod, and the raw materials are stirred and mixed by the mixing plate and the movable stirring rod. At the same time, the heating rod The reaction liquid is heated by the heating plate, and the mixing of the reaction liquid can be ensured by the rotating movable stirring rod, the mixing plate and the heating rod. The fourth water pump working at the same time can transport the reaction liquid at the bottom and the middle of the reaction tank to the top of the reaction tank, so as to ensure the mixing degree and pH value of the reaction liquid in the upper, middle and lower parts of the reaction tank. At the same time, the pH value detection electrode can monitor the pH value of the reaction liquid in real time, and the temperature detection sensor can monitor the temperature of the upper, middle and lower layers of the reaction liquid in real time. When the first rotating rod drives the bottom stirring rod and the mixing plate to rotate for a certain period of time, the mixing motor is turned off at this time. Due to the resistance, the first rotating rod, the bottom stirring rod and the mixing plate stop rotating soon. Since the mixing plate no longer rotates, the mixing plate is no longer subjected to the centrifugal force. At this time, the movable stirring rod and the mixing plate are reset under the action of the first spring's own rebound force, and then the mixing motor works again, and the output end of the mixing motor drives the first rotating rod, the movable stirring rod and the mixing plate to reverse, and the reaction liquid is stirred and mixed again, and this is repeated continuously to ensure sufficient mixing and sufficient reaction of the reaction liquid, thereby improving the utilization rate of the raw materials, and obtaining gray water anti-scaling dispersant with a certain concentration and crystalline state after sufficient reaction. At this time, the fully reacted raw materials are input into the separation tank through the first transfer pipeline, the second water pump and the separation pipeline, and the separation motor and the first motor work at the same time, and the output end of the separation motor drives the centrifugal separation screen to rotate through the second rotating rod. After the reaction liquid falls on the top of the centrifugal separation screen,Under the action of centrifugal force, the crystals in the crystallized state in the reaction liquid are dispersed to the surroundings, and finally slide down through the inner wall of the separation tank. Crystals of different sizes can be screened out through three sets of centrifugal separation screens. At the same time, the output end of the first motor drives the worm wheel rotating plate, the rotating block, the second slider and the scraper to rotate through the worm. The rotating scraper can push the screened crystals to the discharge port, and finally discharge them from the separation tank through the discharge port, slide and collect through the discharge plate, and the gray water anti-scaling dispersant liquid with a certain concentration after filtration is collected at the lowest end of the separation tank, and then transported to the inside of the three sets of liquid storage tanks through the second transfer pipeline and the third water pump. Storage, users can transport the ash water anti-scaling dispersant with a certain concentration to the next process through the third transfer pipeline. This device can not only perform real-time temperature detection but also real-time pH detection to ensure the normal progress of the reaction. At the same time, it can improve the mixing effect of raw materials and the utilization rate of raw materials under the premise of reducing the load when the mixing motor starts, and can also improve the yield rate of products, thereby reducing the production cost of users. This device can also perform automatic screening work, which can greatly reduce the content of crystals in the liquid, which can not only reduce the workload of users, but also improve the screening effect and screening efficiency.

[0032] Working principle: When the user uses the device, the user adds the raw material into the raw material tank 2, and inputs the raw material into the reaction tank 1 through the first water pump 4 and the raw material pipeline 3. While inputting, the raw material ratio can be controlled through the proportioning box 5, so that the raw material can be added into the reaction tank 1 according to the set ratio. The user adds the set clean water and gas into the reaction tank 1 through the air pipe 14 and the water pipe 15, and the pressure inside the reaction tank 1 can be monitored through the pressure sensor 16. At the same time, the user controls the heating plate 17 and the heating rod 25 to work. When the inside of the reaction tank 1 reaches the set raw material, the mixing motor 19 works, and the output end of the mixing motor 19 drives the first rotating rod 20 to rotate, and the first rotating rod 20 drives the bottom stirring rod 21, the movable The stirring rod 23 and the mixing plate 24 rotate, and the raw materials at the bottom of the reaction tank 1 can be stirred through the bottom stirring rod 21. Since the mixing plate 24 and the movable stirring rod 23 are close to the first rotating rod 20, when the mixing motor 19 drives the first rotating rod 20 and the mixing plate 24 to rotate, it does not require too much load, which facilitates the start of the mixing motor 19 and reduces the damage to the mixing motor 19. When the mixing motor 19 drives the first rotating rod 20 and the mixing plate 24 to rotate faster and faster, the mixing plate 24 moves to the side away from the first rotating rod 20 under the action of centrifugal force, and the mixing plate 24 drives the movable stirring rod 23 to slide inside the sliding hole 22, and the fixed slider 30 slides inside the movable stirring rod 23. The movable stirring rod 23 can stretch and compress the first spring 31 while moving, and the movable stirring rod 23 drives the first slider 29 to slide inside the first slide groove 27 and the second slide groove 28 until the first slider 29 conflicts with one end of the first rotating rod 20 and the second slide groove 28. At this time, the mixing plate 24 no longer moves to the side away from the first rotating rod 20, and the raw materials are stirred and mixed by the mixing plate 24 and the movable stirring rod 23. At the same time, the reaction liquid is heated by the heating rod 25 and the heating plate 17. The rotating movable stirring rod 23, the mixing plate 24 and the heating rod 25 can ensure the mixing of the reaction liquid and the uniformity of the temperature of the reaction liquid. At the same time, the working fourth water pump 33 can heat the bottom and The reaction liquid in the middle is transported to the top of the reaction tank 1, so as to ensure the mixing degree and pH value of the reaction liquid in the upper, middle and lower parts of the reaction tank 1. At the same time, the pH value detection electrode 35 can monitor the pH value of the reaction liquid in real time. At the same time, the temperature detection sensor 18 can monitor the temperature of the three layers of the reaction liquid in real time. When the first rotating rod 20 drives the bottom stirring rod 21 and the mixing plate 24 to rotate for a certain period of time, the mixing motor 19 is turned off. Due to the existence of resistance, the first rotating rod 20, the bottom stirring rod 21 and the mixing plate 24 stop rotating soon. Since the mixing plate 24 no longer rotates, the mixing plate 24 is no longer subjected to centrifugal force. At this time, the movable stirring rod 23 and the mixing plate 24 are reset under the action of the first spring 31's own resilience.The second chute 28, the first chute 27 and the receiving groove 26 can ensure the stability of the movement of the movable stirring rod 23, and then the mixing motor 19 works again, and the output end of the mixing motor 19 drives the first rotating rod 20, the movable stirring rod 23 and the mixing plate 24 to reverse, and the reaction liquid is stirred and mixed again, and this is repeated continuously to ensure the full mixing and full reaction of the reaction liquid, thereby improving the utilization rate of the raw materials, and after the full reaction, the gray water anti-scaling dispersant with a certain concentration and a crystalline state is obtained. At this time, the fully reacted raw materials are input into the separation tank 6 through the first transfer pipeline 7, the second water pump 9 and the separation pipeline 8. The separation motor 37 and the first motor 46 work at the same time. The output end of the separation motor 37 drives the centrifugal separation screen 38 to rotate through the second rotating rod 36. After the reaction liquid falls on the top of the centrifugal separation screen 38, the crystals in the crystallized state in the reaction liquid are dispersed to the surroundings under the action of centrifugal force, and finally slide down through the inner wall of the separation tank 6. The crystals of different sizes can be screened out through the three groups of centrifugal separation screens 38, and can be screened and filtered again through the separation screen plate 39. At the same time, the output end of the first motor 46 drives the worm 45 to rotate, and the rotating worm 45 drives the worm wheel rotating plate 42 to rotate, and the rotating worm wheel rotating plate 42 drives The movable rotating block 44 rotates inside the rotating groove 43. The rotating groove 43 and the rotating block 44 can ensure the stability of the rotation of the worm gear rotating plate 42. The rotating worm gear rotating plate 42 drives the scraper 47 to rotate through the third slide groove 48 and the second slider 49. The rotating scraper 47 can push the screened crystals to the discharge port 40, and finally discharge the crystals from the separation tank 6 through the discharge port 40, slide and collect through the discharge plate 41, and the gray water anti-scaling dispersant liquid with a certain concentration after filtration is collected at the lowest end of the separation tank 6, and then transported to the inside of the three groups of liquid storage tanks 10 for storage through the second transfer pipeline 11 and the third water pump 12. The user The ash water anti-scaling dispersant with a certain concentration can be transported to the next process through the third transfer pipeline 13. This device can not only perform real-time temperature detection but also real-time pH detection to ensure the normal progress of the reaction. At the same time, it can improve the mixing effect of raw materials and the utilization rate of raw materials under the premise of reducing the load when the mixing motor 19 is started, and can also improve the yield of products, thereby reducing the production cost of users. This device can also perform automatic screening work, which can greatly reduce the content of crystals in the liquid, which can not only reduce the workload of users, but also improve the screening effect and screening efficiency.
