[0032] Furthermore, the adding mechanism includes a support plate 11 fixedly arranged on the top of the frame 1, the support plate 11 is penetrated by a first vertical groove 12, a horizontal groove 13 and a second vertical groove 14, and the first vertical groove 12, the horizontal groove 13 and the second vertical groove 14 are connected, a slide bar 15 is fixed on one side of the support plate 11 and the outside of the slide bar 15 is slidably connected to a movable block 16, the inside of the movable block 16 is slidably connected to a cross bar 17, a forward and reverse motor 18 is fixed on the front of the support plate 11, the output end of the forward and reverse motor 18 penetrates to the back of the support plate 11 and is fixed with a movable rod 19, the movable rod 19 is penetrated by a hollow groove 20, a round rod 21 is fixed inside one end of the cross bar 17, and the round rod 21 penetrates the hollow groove 20 and the first vertical groove 12.

[0033] Next, the first vertical groove 12 and the second vertical groove 14 are slidably connected with a cushion block 46 and a first spring 22, a vertical rod 23 is fixed to the bottom of the cushion block 46, a groove 24 is provided at the bottom of the support plate 11, a pressure plate 25 is slidably connected to the inner wall of the groove 24 and an airbag 26 is provided, the bottom of the vertical rod 23 penetrates into the groove 24 and is fixedly connected to the top of the pressure plate 25, a nozzle 27 is connected to the bottom of the airbag 26, the vertical rod 23 penetrates the first spring 22, and the nozzle 27 is located at the position of the drive motor 8.

[0034] It should be noted that the forward and reverse motors 18 are started to drive the movable rod 19 to rotate. Since the round rod 21 at one end of the cross bar 17 penetrates the hollow groove 20, the hollow groove 20 will move outside the round rod 21 when the movable rod 19 rotates, and will carry the round rod 21 from the bottom of the first vertical groove 12 to the top of the first vertical groove 12. During this process, the cross bar 17 will rise vertically and the movable block 16 will slide upward on the outside of the slide bar 15. This operation is to make the bottom of the hollow cylinder 28 higher than the highest point of the storage box 7. As the movable rod 19 continues to rotate, the round rod 21 at this time rises from the bottom of the first vertical groove 12 to the top of the first vertical groove 12. Move to the transverse groove 13. During this process, the cross bar 17 will slide in the movable block 16 but the movable block 16 will not move. This operation is to move the hollow cylinder 28 to the top of the storage box 7. Then with the rotation of the movable rod 19, the round rod 21 moves from the transverse groove 13 to the bottom of the second vertical groove 14, and then the movable block 16 and the cross bar 17 will drop vertically. This operation is to allow the hollow cylinder 28 to enter the interior of the storage box 7. When the liquid to be extracted is sodium hydroxide solution, the hollow cylinder 28 in the extraction unit will enter the compartment where the sodium hydroxide solution is located under the above operation.

[0035] Furthermore, an extraction unit is provided at one end of the cross bar 17, and the extraction unit includes a hollow cylinder 28 fixedly provided at one end of the cross bar 17, a piston is provided inside the hollow cylinder 28, and a piston rod 29 is fixed on the top of the piston, a round plate 31 is fixed on the top of the piston rod 29, a cylinder 32 is fixed at the bottom of one end of the cross bar 17, and the output end of the cylinder 32 passes through the top of the cross bar 17 and is fixedly connected to the round plate 31, and a scale line is provided on the outside of the hollow cylinder 28, and the output end of the cylinder 32 is fixed to the top of the cross bar 17. The end extends out to drive the circular plate 31 and the piston rod 29 to rise, and then the sodium hydroxide solution will be extracted into the hollow cylinder 28, and then the forward and reverse motor 18 rotates in the opposite direction, and then drives the hollow cylinder 28 back to the top of the addition port 3 and descends, and then the solenoid valve in the addition port 3 is started to open the addition port 3, and then the hollow cylinder 28 descends to the inside of the addition port 3, and then the output end of the cylinder 32 retracts to drive the piston rod 29 and the piston to descend in the hollow cylinder 28, and then the sodium hydroxide solution in the hollow cylinder 28 is squeezed out into the reactor.

[0036] Next, the cleaning mechanism includes a support column 33 at the bottom of the frame 1, the support column 33 extends to the interior of the reactor 2, a hollow rod 34 is fixed to the top of the support column 33, a thin plate 35 is fixed to the bottom of the hollow rod 34, a support foot and a hook 36 are fixed to the bottom of the reactor 2, a hollow stirring shaft 37 is fixed to one end of the hollow rod 34, a rectangular block 38 is slidably connected to the inside of the hollow rod 34, a second spring 39 and a pull rope 40 are fixed to one end of the rectangular block 38, the pull rope 40 passes through the hollow rod 34 and the support column 33 in sequence and is led out from the bottom end of the reactor 2, one end of the rectangular block 38 is located inside the stirring shaft 37 and a scraper 41 is fixed thereto, the stirring shaft 37 is provided with an opening 42, strip grooves 43 are provided on both sides of the opening 42, a third spring 44 is fixed to the inside of the strip groove 43, and a scraper 45 is fixed to one end of the third spring 44.

[0037] It can be concluded that, in the initial state, the pull rope 40 is in a tensioned state and the bottom of the pull rope 40 is wound around the hook 36. When the pull rope 40 is in a tensioned state, the rectangular block 38 will retreat and compress the second spring 39, and then the scraper 41 will enter the inside of the stirring shaft 37 from the position of the opening 42. Therefore, in the initial state, the scraper 41 is located inside the stirring shaft 37. When the reactor 2 rotates, the liquid inside will hit the thin plate 35 and the stirring shaft 37. When the collision occurs, water waves are formed to enter and stir the liquid in the reactor 2. However, after a certain period of use, impurities will adhere to the inner wall of the reactor 2. At this time, the pull rope 40 needs to be loosened from the hook 36, and then the second spring 39 resets the rectangular block 38 to move the scraper 41 from the stirring shaft 37, and then the blade of the scraper 41 contacts the inner wall of the reactor 2. When the reactor 2 rotates, the scraper 41 scrapes off the impurities inside it. When scraping, the water in the water tank 4 will enter the reactor 2, and then the water and impurities will be discharged from the discharge port at the bottom of the reactor 2, thereby realizing the two functions of stirring and cleaning.

[0038] Working principle: A filling port is provided on the back of the water tank 4, through which water and alum can be injected into the water tank 4. A certain amount of sodium hydroxide solution, hydrogen peroxide, mixed dispersant and lauroyl chloride are placed in the four compartments inside the storage box 7 respectively. After the water pump is turned on, the water in the water tank 4 is discharged from the water pipe to the reactor 2, and then the driving motor 8 is started to drive the first bevel gear and the gear to rotate. When the gear rotates, the reactor 2 is driven to rotate through the action of the teeth. The rotation of the first bevel gear drives the stirring blade 9 to rotate in the water tank 4 through the second bevel gear. The rotation of the stirring blade 9 makes the water and alum merge quickly to purify the water quality. The rotation of the reactor 2 can achieve the stirring of the internal liquid. After the stirring is turned on, sodium hydroxide solution needs to be added to the inside of the reactor 2. During this process, the chilled water is turned on to cool the reaction system to less than 15°C, and then hydrogen peroxide is added to the reactor. After the addition is completed, add the mixed dispersant, add lauroyl chloride dropwise at 0-15°C, and continue to keep warm and stir for 30 minutes (the entire reaction process is carried out under normal pressure). After the reaction is completed, discharge the material into the washing bucket to filter out the mother liquor and remove the lower aqueous phase (salt-containing wastewater). Then wash with deionized water to remove the aqueous phase (washing wastewater). Then use a dryer (using warm water (30-35°C) as a heat source and automatic control) to vacuum dry and dehydrate to obtain the product. The addition process is as follows:

[0039] The forward and reverse motor 18 is started to drive the movable rod 19 to rotate. Since the round rod 21 at one end of the cross bar 17 penetrates the hollow groove 20, the hollow groove 20 will move outside the round rod 21 when the movable rod 19 rotates, and will bring the round rod 21 from the bottom of the first vertical groove 12 to the top of the first vertical groove 12. In this process, the cross bar 17 will rise vertically and the movable block 16 will slide upward outside the slide bar 15. This operation is to make the bottom of the hollow cylinder 28 higher than the highest point of the storage box 7. As the movable rod 19 continues to rotate At this time, the round rod 21 moves from the first vertical groove 12 to the horizontal groove 13. During this process, the horizontal rod 17 will slide in the movable block 16, but the movable block 16 will not move. This operation is to move the hollow cylinder 28 to the top of the storage box 7. Then, with the rotation of the movable rod 19, the round rod 21 moves from the horizontal groove 13 to the bottom of the second vertical groove 14, and then the movable block 16 and the horizontal rod 17 will drop vertically. This operation is to make the hollow cylinder 28 enter the interior of the storage box 7. Before the adding mechanism works, the electromagnetic slider 6 is The outside of the electromagnetic slide rail 5 moves and moves the storage box 7 with it, the purpose is to move the compartment where the extracted solution is located to the position of the hollow cylinder 28, so that the hollow cylinder 28 and the compartment are in a straight line to facilitate the extraction of liquid. When the liquid to be extracted is sodium hydroxide solution, the hollow cylinder 28 in the extraction unit will enter the compartment where the sodium hydroxide solution is located under the above operation, and then the output end of the cylinder 32 will extend to drive the circular plate 31 and the piston rod 29 to rise, and then the sodium hydroxide solution will be extracted into the hollow cylinder 28, and then The counter motor 18 rotates in the reverse direction, and then brings the hollow cylinder 28 back to the top of the addition port 3 and descends. Then the solenoid valve in the addition port 3 is started to open the addition port 3. Then the hollow cylinder 28 descends to the inside of the addition port 3. Then the output end of the cylinder 32 retracts and brings the piston rod 29 and the piston down in the hollow cylinder 28. Then the sodium hydroxide solution in the hollow cylinder 28 is squeezed out into the reactor. The same operation is performed when extracting hydrogen peroxide, mixed dispersant, and lauroyl chloride. The labor cost is reduced by automatic addition.

[0040] When the round rod 21 moves in the first vertical groove 12 and the second vertical groove 14, it will compress the pad 46, and then the pad 46 will move down with the vertical rod 23 and compress the first spring 22. When the round rod 21 leaves the top of the pad 46, the pad 46 is lifted under the reset action of the first spring 22, and then the pad 46 can be lifted and lowered. When the pad 46 is lifted and lowered, the vertical rod 23 will lift and lower the pressure plate 25. When the pressure plate 25 descends, it compresses the airbag 26 and then the air in the airbag 26 is discharged from the nozzle 27 and sprayed toward the drive motor 8. This is beneficial to achieve auxiliary cooling of the drive motor 8 on the basis of adding liquid through this operation to increase its service life.

[0041] In the initial state, the pull rope 40 is in a tensioned state and the bottom of the pull rope 40 is wrapped around the hook 36. When the pull rope 40 is in a tensioned state, the rectangular block 38 will retreat and compress the second spring 39, and then the scraper 41 will enter the inside of the stirring shaft 37 from the position of the opening 42. Therefore, in the initial state, the scraper 41 is located inside the stirring shaft 37. When the reactor 2 rotates, the liquid inside will hit the thin plate 35 and the stirring shaft 37. When the collision occurs, water waves are formed to enter and stir the liquid in the reactor 2. However, after a certain period of use, impurities will adhere to the inner wall of the reactor 2. At this time, the pull rope 40 needs to be loosened from the hook 36, and then the second spring 39 resets the rectangular block 38 resets and moves the scraper 41 out of the stirring shaft 37 , and then the blade of the scraper 41 contacts the inner wall of the reactor 2. When the reactor 2 rotates, the scraper 41 scrapes off the impurities inside it. When scraping, the water in the water tank 4 will enter the reactor 2, and then the water and impurities will be discharged from the discharge port at the bottom of the reactor 2, thereby realizing the two functions of stirring and cleaning. After cleaning, it is necessary to tighten the pull rope 40 again, and then the scraper 41 returns to the stirring shaft 37. When returning, the scraper 45 contacts the side wall of the scraper 41, so that the impurities on the side wall of the scraper 41 can be removed by the scraper 45 to prevent the impurities from being brought into the stirring shaft 37. The scraper 41 will push against the scraper 45 during the process of going in and out, so that the scraper 45 can expand and contract in the strip groove 43 under the action of the third spring 44.

[0042] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
