Description

Technical Field

[0001] The present invention belongs to the technical field of wastewater treatment, and specifically relates to an electro-dialysis neutralization device for wastewater and sewage. Background Art

[0002] Wastewater refers to the general term for the water discharged during the activities of residents and the runoff rainwater. Sewage usually refers to the polluted water discharged from life and production, and the water that has lost its original use function is simply called sewage. In actual discharge, the pH values of some wastewater and sewage do not meet the discharge standards, and pH adjustment is required to achieve up-to-standard discharge. Generally, electro-dialysis is used to neutralize wastewater and sewage.

[0003] The patent with the publication number CN212476219U discloses an electro-dialysis neutralization device for wastewater and sewage, belonging to the technical field of wastewater treatment, which is used to solve the problem that the existing electro-dialysis neutralization device cannot quickly and efficiently neutralize acid-base ions in wastewater and sewage. It includes a tank body and a stirring mechanism. The upper side of the tank body is successively provided with a water injection pipe and a mounting plate. A motor is fixed on the mounting plate. Inside the tank body, an anode partition plate and a cathode partition plate are successively arranged. An anion exchange membrane and a cation exchange membrane are respectively arranged on the anode partition plate and the cathode partition plate. The anode partition plate and the cathode partition plate divide the inside of the tank body into an anode chamber, a neutralization chamber and a cathode chamber. The stirring mechanism is rotatably arranged inside the neutralization chamber. Symmetric slots are opened on the upper side of the tank body, and an anode plate and a cathode plate are respectively slidably arranged inside the slots; this patent improves the fluidity of wastewater and sewage, makes the reaction more sufficient, and can detect the pH value of wastewater and sewage, and control the current magnitude of the anode plate and the cathode plate to make the pH value of wastewater and sewage meet the discharge requirements.

[0004] However, the above technical solution still has the following deficiencies in the actual application process: After the wastewater and sewage are injected into the tank body, the anode plate and the cathode plate are electrified. Anions in the wastewater and sewage enter the anode chamber through the anion exchange membrane, and cations enter the cathode chamber through the cation exchange membrane, and concentrated solutions are generated in the anode chamber and the cathode chamber. At the same time, the stirring blades are driven to rotate to make the wastewater and sewage react fully with the anion and cation exchange membranes, thereby adjusting the pH value of the wastewater and sewage. Although the pH adjustment effect can be achieved in this way, in some cases, the wastewater may contain some substances with strong binding ability to hydrogen ions or hydroxide ions, which will hinder the normal migration of ions, resulting in slow pH adjustment speed or failure to meet the discharge standard. Therefore, in order to accelerate the pH adjustment progress, an alkaline neutralizing material is appropriately added to the wastewater and sewage. However, in actual operation, when the alkaline neutralizing material is added to the tank body, the situation of excessive or insufficient addition may occur. Excessive addition will not only cause overshoot of the pH value but also result in waste of the reagent; while too little addition of the reagent will lead to slow adjustment progress.

[0016] The beneficial effects of the present invention are as follows: 1. For the electro-dialysis neutralization device for wastewater and sewage of the present invention, by using the alkaline neutralizing material adding component, when the adjustment speed of the pH value of the wastewater and sewage is slow and it is necessary to add alkaline neutralizing materials for auxiliary adjustment, the addition amount of the alkaline neutralizing materials can be accurately controlled. Thus, when the alkaline neutralizing materials are added into the tank body, the situation of overshoot of the pH value caused by excessive addition and the waste of the medicament can be avoided. At the same time, the situation of slow adjustment progress caused by too little addition of the medicament can also be avoided. And, compared with the method of controlling the feeding amount by intermittently starting and stopping an electromagnetic valve for a period of time, this method can ensure the accuracy of the single feeding amount and will not be affected by the flow rate of the alkaline neutralizing materials, which is more accurate.

[0017] 2. The electro-dialysis neutralization device for wastewater and sewage described in the present invention can cut the alkaline neutralizing material by rotating the blade after receiving the alkaline neutralizing material in the storage barrel, so as to disperse the agglomerated alkaline neutralizing material. Moreover, during the cutting process, the storage barrel is in a rotating state, and the alkaline neutralizing material inside it will also be in a tumbling state. Then, under the synergistic effect of the rotation of the blade and the tumbling of the alkaline neutralizing material, the pulverization uniformity can be improved. That is, when the storage barrel pours out the alkaline neutralizing material, it can ensure that there is no agglomeration of the alkaline neutralizing material, thereby improving the subsequent reaction efficiency. And when the storage barrel pours out the alkaline neutralizing material, it drives the blade to retract into the inner cavity of the rotating barrel. During the retraction of the blade, the alkaline neutralizing material on its surface will fall off, and when the adjusting plate moves to the mouth of the rotating barrel, the adjusting plate will scrape the alkaline neutralizing material adhering to the inner wall of the storage barrel and the outer wall of the rotating barrel, causing the alkaline neutralizing material to fall off. Thus, when the storage barrel pours out the alkaline neutralizing material, it avoids the situation that the addition amount of the alkaline neutralizing material is insufficient due to the alkaline neutralizing material adhering to the surface of the blade, the outer wall of the rotating barrel, and the inner wall of the storage barrel, which in turn affects the subsequent reaction efficiency.

[0018] 3. The electro-dialysis neutralization device for wastewater and sewage described in the present invention utilizes the integrated component for dispersing and preventing jamming. After the storage barrel pours out the alkaline neutralizing material, it will contact the rotating dispersing plate, and the dispersing plate will disperse the alkaline neutralizing material, making it evenly dispersed inside the tank body. At this time, the stirring blades will stir the alkaline neutralizing material and the wastewater and sewage again, which can be mixed faster and is beneficial to improving the mixing efficiency. In addition, when there is no more alkaline neutralizing material falling in the storage barrel and the adjusting plate moves to the mouth of the storage barrel and the surface of one side of the adjusting plate is flush with the end of the rotating barrel, the scraping blade will scrape off the alkaline neutralizing material adhering to the adjusting plate and the end of the rotating barrel, and it will slide along the surface of the conical block to the dispersing plate and then be dispersed by the dispersing plate again, thus realizing the removal of the alkaline neutralizing material adhering to the adjusting plate and the end of the rotating barrel, and further ensuring the addition amount of the alkaline neutralizing material. Then, after the scraping blade completes the scraping action, it is driven to align with the center position of the adjusting plate and the dispersing plate is reset to the initial position. At this time, multiple angle blocks are all aligned with the angle between adjacent two dispersing plates, and multiple angle blocks are driven to descend simultaneously. Since the angle blocks correspond to the angles between adjacent two dispersing plates, the angle blocks will push the alkaline neutralizing material stuck here to fall off, thus ensuring the subsequent use effect of the dispersing plate and also ensuring the addition amount of the alkaline neutralizing material.

[0022] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 11, the present invention provides a technical solution: a wastewater and sewage electrodialysis neutralization device, including a tank body 1, an anion exchange membrane 39, an anode partition plate 7, and an anode plate 6 are arranged on the left side of the inner cavity of the tank body 1, a cation exchange membrane 8, a cathode partition plate 37, and a cathode plate 38 are arranged on the right side of the inner cavity of the tank body 1, a water inlet pipe 36 is arranged on one side of the tank body 1, a stirring shaft 4 is rotatably arranged in the middle of the bottom of the inner cavity of the tank body 1, a plurality of stirring blades 5 are arranged on the stirring shaft 4, and an alkaline neutralizing material adding assembly is further arranged at the upper end of the tank body 1; The alkaline neutralizing material adding assembly includes a fixed shell 42 fixedly connected to one side of the upper end surface of the tank body 1. Openings are arranged in the middle of the upper and lower sides of the fixed shell 42. One side of the upper end of the fixed shell 42 is fixedly connected to a storage hopper 2. The bottom of the storage hopper 2 is communicated with the upper opening of the fixed shell 42. A rotating ring 3 is rotatably arranged on one side of the inner cavity of the fixed shell 42. A circular through hole is arranged on one side of the rotating ring 3, and a storage cylinder 10 is fixedly connected at the circular through hole. A cylinder 9 is fixedly connected to one side of the inner cavity of the rotating ring 3. The piston end of the cylinder 9 is fixedly connected to an adjusting plate 11. The adjusting plate 11 is attached to the inner cavity wall of the storage cylinder 10. One side of the lower end surface of the adjusting plate 11 is fixedly connected to a fixing plate 12. One side of the lower end of the fixing plate 12 is fixedly connected to a sliding rod 15. The upper end of the sliding rod 15 is fixedly connected to the adjusting plate 11. The sliding rod 15 is slidably connected to a threaded block 18. A rotating cylinder 17 is rotatably arranged in the middle of the upper end surface of the threaded block 18. A circular through hole is arranged in the middle of the adjusting plate 11, and the outer wall of the rotating cylinder 17 is attached to the hole wall of this circular through hole, and the rotating cylinder 17 can move at the circular through hole.

[0024] In this embodiment, as Figure 2 and Figure 10 , Figure 11 shown, a motor six 40 is fixedly connected to the middle of the lower end of the tank body 1. The output end of the motor six 40 is fixedly connected to one end of the stirring shaft 4. A PH sensor 43 is arranged on one side of the bottom of the tank body 1.

[0025] A motor seven 41 is fixedly connected to one side of the outer wall of the fixed shell 42. The output end of the motor seven 41 is fixedly connected to the rotating ring 3.

[0026] Specifically, in the prior art, after wastewater and sewage are injected into the tank body 1, the anode plate 6 and the cathode plate 38 are energized. Anions in the wastewater and sewage enter the anode chamber through the anion exchange membrane 39, and cations enter the cathode chamber through the cation exchange membrane 8, and concentrated solutions are generated in the anode chamber and the cathode chamber. At the same time, the stirring blades are driven to rotate to make the wastewater and sewage fully react with the anion and cation exchange membranes, thereby adjusting the pH value of the wastewater and sewage. Although the pH value can be adjusted in this way, in some cases, the wastewater may contain some substances with strong binding ability to hydrogen ions or hydroxide ions, which will hinder the normal migration of ions, resulting in a slow pH adjustment speed or failure to meet the discharge standard. Therefore, in order to accelerate the pH adjustment progress, an alkaline neutralizing material is appropriately added to the wastewater and sewage. However, in actual operation, when the alkaline neutralizing material is added to the tank body 1, the amount added may be excessive or insufficient. Excessive addition will not only cause overshoot of the pH value but also result in waste of the reagent; while too little addition of the reagent will lead to a slow adjustment progress.

[0027] Therefore, to solve the above problems, in the use of this embodiment, the wastewater and sewage are added into the inner cavity of the tank body 1 through the water inlet pipe 36, the anode plate 6 and the cathode plate 38 are energized, anions in the wastewater and sewage enter the anode chamber through the anion exchange membrane 39, and cations enter the cathode chamber through the cation exchange membrane 8, and concentrated solutions are generated in the anode chamber and the cathode chamber. At the same time, the motor six 40 drives the stirring shaft 4 to rotate, and the wastewater and sewage are stirred by the stirring blades 5 to accelerate the reaction speed. The concentrated solutions in the anode chamber and the cathode chamber can be discharged for collection and utilization. The pH value of the wastewater and sewage can be detected by the pH sensor 43. After meeting the discharge requirements, the valve on the drain pipe at the bottom of the tank body 1 is opened to discharge the wastewater and sewage.

[0028] When the pH value of wastewater and sewage is adjusted slowly and it is necessary to add alkaline neutralizing materials for auxiliary adjustment, the alkaline neutralizing materials are added to the storage hopper 2. Generally, the alkaline neutralizing materials can be calcium hydroxide, sodium carbonate, etc., all of which are solid powders. After the alkaline neutralizing materials enter the storage hopper 2, they will fall due to gravity. If the circular through-hole of the rotating ring 3 is aligned with the discharge port at the lower end of the storage hopper 2, the alkaline neutralizing materials will fall into the storage cylinder 10. Then, the motor seven 41 is used to drive the rotating ring 3 to rotate, so that the storage cylinder 10 is no longer aligned with the feeding port at the bottom of the storage hopper 2. The storage cylinder 10 makes a circular motion. The storage cylinder 10 will only carry the alkaline neutralizing materials below the cylinder mouth to move, and the rest of the alkaline neutralizing materials will still stay in the storage hopper 2 due to the support of the outer wall of the rotating ring 3. Moreover, after the storage cylinder 10 moves away from the bottom of the storage hopper 2, its cylinder mouth is covered by the inner wall of the fixed shell 42, and the alkaline neutralizing materials will not overflow from the storage cylinder 10. When the cylinder mouth of the storage cylinder 10 is aligned with the lower opening of the fixed shell 42, the alkaline neutralizing materials will fall into the interior of the tank body 1 through the upper opening of the tank body 1, that is, a single addition of the alkaline neutralizing materials is realized. Repeating the above operation again can realize multiple additions of the alkaline neutralizing materials. And by driving the adjusting plate 11 to slide in the inner cavity of the storage cylinder 10 through the cylinder 9 and adjusting the distance between the upper end surface of the storage cylinder 10 and the upper end surface of the adjusting plate 11, the quantity of the alkaline neutralizing materials that the storage cylinder 10 can pick up at one time can be controlled. At the same time, by driving the rotating ring 3 to rotate intermittently and controlling the feeding frequency, the addition amount of the alkaline neutralizing materials can be accurately controlled according to the pH value detected by the pH sensor 43 in real time. Thus, when the alkaline neutralizing materials are added to the tank body 1, the situation of overshoot of the pH value caused by excessive addition and the waste of the medicament are avoided. At the same time, the situation of slow adjustment progress caused by too little addition of the medicament is also avoided. And compared with the method of controlling the feeding amount by intermittently starting and stopping the solenoid valve for a period of time, this method can ensure the accuracy of the single feeding amount and will not be affected by the flow rate of the alkaline neutralizing materials, which is more accurate.

[0029] In this embodiment, as Figure 5 and Figure 6 shown, one end of the threaded block 18 is threadedly connected to the first threaded rod 14. One end of the first threaded rod 14 is rotatably arranged on the adjusting plate 11, and the other end is rotatably arranged on the fixing plate 12. One side of the lower end of the fixing plate 12 is fixedly connected to the first motor 13. The output end of the first motor 13 is fixedly connected to one end of the first threaded rod 14.

[0030] One side of the lower end surface of the threaded block 18 is fixedly connected to the second motor 16. The output end of the second motor 16 is fixedly connected to one end of the rotating cylinder 17.

[0031] On both sides of the bottom of the inner cavity of the rotating cylinder 17, there are sliding connections with supporting rods 23. On one side of the supporting rod 23, there are fixedly connected multiple blades 24. The blades 24 are inserted and slidably connected to one side of the rotating cylinder 17. One end of the supporting rod 23 is rotatably provided with a connecting rod 22. One end of the connecting rod 22 is rotatably provided with an adjusting block 21. On one side of the adjusting block 21, there is a threaded connection with a second threaded rod 20. One end of the second threaded rod 20 is rotatably provided on one side of the inner cavity of the rotating cylinder 17. On one side of the inner cavity of the rotating cylinder 17, there is fixedly connected a third motor 19. The output end of the third motor 19 is fixedly connected to one end of the second threaded rod 20.

[0032] Specifically, in the above embodiment, although the solid powder-like alkaline neutralizing material can be added to the tank body 1, however, since some of the solid powder-like alkaline neutralizing material may agglomerate, resulting in the agglomerated alkaline neutralizing material requiring a longer time to fully react after being added to the tank body 1, thus affecting the treatment efficiency; Therefore, to solve the above problems, when in use in this embodiment, when the storage cylinder 10 receives the alkaline neutralizing material, the upper end of the rotating cylinder 17 is always flush with the upper surface of the adjusting plate 11, without occupying the volume of the storage cylinder 10. After the storage cylinder 10 is moved away from the bottom of the storage hopper 2, the adjusting plate 11 moves away from the opening of the storage cylinder 10 and moves to the other side edge of the storage cylinder 10. At the same time, the first motor 13 drives the first threaded rod 14 to rotate, causing the threaded block 18 to move, so that the upper end of the rotating cylinder 17 moves to the opening of the storage cylinder 10. Then, the third motor 19 drives the second threaded rod 20 to rotate, the adjusting block 21 drives the connecting rod 22 to rotate, and the two side supporting rods 23 slide simultaneously and in different directions, causing the blades 24 to extend out of the inner cavity of the rotating cylinder 17. Then, the second motor 16 drives the rotating cylinder 17 to rotate, and the agglomerated alkaline neutralizing material can be dispersed by the rotation of the blades 24. And during the cutting process, the storage cylinder 10 is in a rotating state, and the alkaline neutralizing material inside it will also be in a tumbling state. Then, under the synergistic action of the rotation of the blades 24 and the tumbling of the alkaline neutralizing material, the pulverization uniformity can be improved; that is, when the storage cylinder 10 pours out the alkaline neutralizing material, it can be ensured that there is no agglomeration of the alkaline neutralizing material, thus improving the subsequent reaction efficiency. And when the storage cylinder 10 pours out the alkaline neutralizing material, it drives the blades 24 to retract into the inner cavity of the rotating cylinder 17. During the retraction of the blades 24, the alkaline neutralizing material on their surfaces will fall off, and the adjusting plate 11 moves to the opening of the rotating cylinder 17. The adjusting plate 11 will scrape the alkaline neutralizing material adhering to the inner wall of the storage cylinder 10 and the outer wall of the rotating cylinder 17, causing the alkaline neutralizing material to fall, thereby avoiding the situation that when the storage cylinder 10 pours out the alkaline neutralizing material, due to the alkaline neutralizing material adhering to the surfaces of the blades 24, the outer wall of the rotating cylinder 17, and the inner wall of the storage cylinder 10, the addition amount of the alkaline neutralizing material is insufficient, which in turn affects the subsequent reaction efficiency.

[0033] In this embodiment, as Figures 7 - 9As shown, a disintegrating and anti-jamming integrated component is further provided on the fixed shell 42; The disintegrating and anti-jamming integrated component includes an L-shaped rod 35 fixedly connected to one side of the outer wall of the fixed shell 42. One side of the lower end of the L-shaped rod 35 is rotatably provided with a rotating block 32. A plurality of disintegrating plates 33 are evenly distributed and fixedly connected around the rotating block 32. One side of the L-shaped rod 35 is slidably connected to an electric push rod 27. The piston end of the electric push rod 27 is fixedly connected with a scraping blade 28. The lower end of the scraping blade 28 is fixedly connected with a tapered block 29. A plurality of lifting rods 30 are fixedly connected around the lower end surface of the tapered block 29. The lower end of the lifting rod 30 is fixedly connected with an included angle block 31. The shape of the included angle block 31 corresponds to the included angle between two adjacent disintegrating plates 33.

[0034] One side of the lower end of the L-shaped rod 35 is fixedly connected with a fifth motor 34. The output end of the fifth motor 34 is fixedly connected to the rotating block 32.

[0035] One end of the electric push rod 27 is threadedly connected with a third threaded rod 26. Both ends of the third threaded rod 26 are rotatably arranged on the L-shaped rod 35.

[0036] One side of the L-shaped rod 35 is fixedly connected with a fourth motor 25. The output end of the fourth motor 25 is fixedly connected to one end of the third threaded rod 26.

[0037] Specifically, in the above embodiment, although the automatic addition of the alkaline neutralizing material can be realized, however, the alkaline neutralizing material only enters the tank body 1 from a fixed position, so the alkaline neutralizing material will be concentrated at the same place inside the tank body 1. When the stirring blades 5 stir the alkaline neutralizing material, it takes a longer time to mix it evenly with the waste water and sewage, which relatively affects the mixing efficiency. And, in the above embodiment, although it can prevent the alkaline neutralizing material from adhering to the inner wall of the storage barrel 10, the surface of the blade 24, and the outer wall of the rotating barrel 17, however, the alkaline neutralizing material is still likely to adhere to the adjusting plate 11 and the end of the rotating barrel 17, which also affects the addition amount of the alkaline neutralizing material. Therefore, to solve the above problems, when in use in this embodiment, after the storage barrel 10 pours out the alkaline neutralizing material, the fifth motor 34 drives the rotating block 32 to rotate. The alkaline neutralizing material will contact the rotating disintegrating plates 33. The disintegrating plates 33 disperse the alkaline neutralizing material, making it evenly dispersed inside the tank body 1. At this time, the stirring blades 5 then stir the alkaline neutralizing material and the waste water and sewage, so that they can be mixed faster, which is beneficial to improving the mixing efficiency.

[0038] When there is no more alkaline neutralizing material falling in the storage cylinder 10, and the adjusting plate 11 moves to the mouth of the storage cylinder 10, and the side surface of the adjusting plate 11 is flush with the end of the rotating cylinder 17, the upper edge of the scraping blade 28 fits against the side surface of the adjusting plate 11. At this time, the electric push rod 27 is used to drive the scraping blade 28 to move horizontally, and the scraping blade 28 scrapes off the alkaline neutralizing material adhering to the adjusting plate 11 and the end of the rotating cylinder 17. Moreover, the alkaline neutralizing material will slide down along the surface of the conical block 29 to the dispersing plate 33, and then be dispersed again by the dispersing plate 33, thus realizing the removal of the alkaline neutralizing material adhering to the adjusting plate 11 and the end of the rotating cylinder 17, and further ensuring the addition amount of the alkaline neutralizing material.

[0039] Since in order to ensure the dispersing efficiency, a plurality of dispersing plates 33 are arranged around the rotating block 32, there will be an included angle between adjacent two dispersing plates 33. When the dispersing plate 33 disperses the alkaline neutralizing material, the alkaline neutralizing material may get stuck at the included angle between the two dispersing plates 33, which not only affects the subsequent use effect of the dispersing plate 33, but also affects the addition amount of the alkaline neutralizing material. Therefore, to avoid this situation, after the scraping blade 28 completes the scraping action, the scraping blade 28 is driven to align with the center position of the adjusting plate 11, and the dispersing plate 33 is reset to the initial position. At this time, a plurality of angle blocks 31 are all aligned with the included angle between adjacent two dispersing plates 33. Then, the fourth motor 25 drives the third threaded rod 26 to rotate, so that a plurality of angle blocks 31 descend simultaneously. Since the angle blocks 31 correspond to the included angle between adjacent two dispersing plates 33, the angle blocks 31 will push off the alkaline neutralizing material stuck here, thus ensuring the subsequent use effect of the dispersing plate 33 and also ensuring the addition amount of the alkaline neutralizing material.

[0040] Working principle: Waste water and sewage are added into the inner cavity of the tank body 1 through the water inlet pipe 36. The anode plate 6 and the cathode plate 38 are electrified. Anions in the waste water and sewage enter the anode chamber through the anion exchange membrane 39, and cations enter the cathode chamber through the cation exchange membrane 8. Concentrated solutions are generated in the anode chamber and the cathode chamber. At the same time, the stirring shaft 4 is driven by the motor six 40, and the waste water and sewage are stirred by the stirring blades 5 to accelerate the reaction rate. The concentrated solutions in the anode chamber and the cathode chamber can be discharged for collection and utilization. The pH value of the waste water and sewage can be detected by the pH sensor 43. After meeting the discharge requirements, the valve on the drain pipe at the bottom of the tank body 1 is opened to discharge the waste water and sewage. When the pH value of the waste water and sewage is adjusted slowly and alkaline neutralizing materials need to be added for auxiliary adjustment, the alkaline neutralizing materials are added into the storage hopper 2. Generally, the alkaline neutralizing materials can be calcium hydroxide, sodium carbonate, etc., all of which are solid powders. After the alkaline neutralizing materials enter the storage hopper 2, they will fall due to gravity. If the circular through hole of the rotating ring 3 aligns with the discharge port at the lower end of the storage hopper 2, the alkaline neutralizing materials will fall into the storage cylinder 10. Then, the rotating ring 3 is driven by the motor seven 41 to rotate, so that the storage cylinder 10 no longer aligns with the feeding port at the bottom of the storage hopper 2. The storage cylinder 10 makes a circular motion. The storage cylinder 10 only carries the alkaline neutralizing materials below the cylinder mouth to move, and the remaining alkaline neutralizing materials will still stay in the storage hopper 2 due to the support of the outer wall of the rotating ring 3. Moreover, after the storage cylinder 10 moves away from the bottom of the storage hopper 2, its cylinder mouth is covered by the inner wall of the fixed shell 42, and the alkaline neutralizing materials will not overflow from the storage cylinder 10. When the cylinder mouth of the storage cylinder 10 aligns with the opening on the lower side of the fixed shell 42, the alkaline neutralizing materials will fall into the interior of the tank body 1 through the upper opening of the tank body 1, that is, a single addition of the alkaline neutralizing materials is realized. Repeating the above operation can realize multiple additions of the alkaline neutralizing materials. And by driving the adjusting plate 11 to slide in the inner cavity of the storage cylinder 10 through the cylinder 9, and adjusting the distance between the upper end face of the storage cylinder 10 and the upper end face of the adjusting plate 11, the quantity of the alkaline neutralizing materials that the storage cylinder 10 can pick up at one time can be controlled. At the same time, by driving the rotating ring 3 to rotate intermittently and controlling the feeding frequency, the addition amount of the alkaline neutralizing materials can be accurately controlled according to the pH value detected by the pH sensor 43 in real time. Thus, when the alkaline neutralizing materials are added into the tank body 1, the situation of overshoot of the pH value caused by excessive addition and waste of the medicament is avoided. At the same time, the situation of slow adjustment progress due to too little addition of the medicament is also avoided. And compared with the method of controlling the feeding amount by intermittently starting and stopping the solenoid valve for a period of time, this method can ensure the accuracy of the single feeding amount, will not be affected by the flow rate of the alkaline neutralizing materials, and is more accurate. When the storage cylinder 10 picks up the alkaline neutralizing materials, the upper end of the rotating cylinder 17 is always flush with the upper surface of the adjusting plate 11, without occupying the volume of the storage cylinder 10.After the storage cylinder 10 is moved away from the bottom of the storage hopper 2, the adjusting plate 11 moves away from the opening of the storage cylinder 10 and moves to the other side edge of the storage cylinder 10. At the same time, the first motor 13 drives the first threaded rod 14 to rotate, causing the threaded block 18 to move, so that the upper end of the rotating cylinder 17 moves to the opening of the storage cylinder 10. Then, the third motor 19 drives the second threaded rod 20 to rotate, and the adjusting block 21 drives the connecting rod 22 to rotate, and the two sides of the support rod 23 slide in different directions at the same time, so that the blade 24 extends out of the inner cavity of the rotating cylinder 17. Then, the second motor 16 drives the rotating cylinder 17 to rotate, and the alkaline neutralizing material can be cut by the rotation of the blade 24, so that the caked alkaline neutralizing material can be dispersed. Moreover, during the cutting process, the storage cylinder 10 is in a rotating state, and the alkaline neutralizing material inside it will also be in a tumbling state. Then, under the synergistic action of the rotation of the blade 24 and the tumbling of the alkaline neutralizing material, the pulverization uniformity can be improved. When the storage cylinder 10 pours out the alkaline neutralizing material, it can ensure that there is no caking of the alkaline neutralizing material, thus improving the subsequent reaction efficiency. Moreover, when the storage cylinder 10 pours out the alkaline neutralizing material, it drives the blade 24 to retract into the inner cavity of the rotating cylinder 17. During the retraction of the blade 24, the alkaline neutralizing material on its surface will fall off, and the adjusting plate 11 moves to the opening of the rotating cylinder 17, and the adjusting plate 11 will scrape the alkaline neutralizing material adhering to the inner wall of the storage cylinder 10 and the outer wall of the rotating cylinder 17, so that the alkaline neutralizing material falls off, thus avoiding the situation that when the storage cylinder 10 pours out the alkaline neutralizing material, the addition amount of the alkaline neutralizing material is insufficient due to the alkaline neutralizing material adhering to the surface of the blade 24, the outer wall of the rotating cylinder 17, and the inner wall of the storage cylinder 10, which further affects the subsequent reaction efficiency. After the storage cylinder 10 pours out the alkaline neutralizing material, the fifth motor 34 drives the rotating block 32 to rotate, and the alkaline neutralizing material will contact the dispersing plate 33 during the rotation process. The dispersing plate 33 disperses the alkaline neutralizing material, so that it is evenly dispersed into the tank body 1. At this time, the stirring blade 5 stirs the alkaline neutralizing material and the waste water and sewage again, so that they can be mixed faster, which is beneficial to improving the mixing efficiency. When there is no more alkaline neutralizing material falling in the storage cylinder 10, and the adjusting plate 11 moves to the opening of the storage cylinder 10 and the side surface of the adjusting plate 11 is flush with the end of the rotating cylinder 17, the upper edge of the scraping blade 28 fits with the side surface of the adjusting plate 11. At this time, the electric push rod 27 is used to drive the scraping blade 28 to move horizontally, and the scraping blade 28 scrapes off the alkaline neutralizing material attached to the adjusting plate 11 and the end of the rotating cylinder 17, and the alkaline neutralizing material will slide down along the surface of the conical block 29 to the dispersing plate 33, and then is dispersed again by the dispersing plate 33, thus realizing the removal of the alkaline neutralizing material adhering to the adjusting plate 11 and the end of the rotating cylinder 17, and further ensuring the addition amount of the alkaline neutralizing material.Since multiple dispersion plates 33 are provided around the rotating block 32 to ensure the dispersion efficiency, there will be an angle between adjacent dispersion plates 33. While the dispersion plates 33 disperse the alkaline neutralizing material, the alkaline neutralizing material may get stuck at the angle between two adjacent dispersion plates 33, which not only affects the subsequent use effect of the dispersion plates 33 but also affects the addition amount of the alkaline neutralizing material. Therefore, to avoid this situation, after the scraping blade 28 completes the scraping action, the scraping blade 28 is driven to align with the center position of the adjusting plate 11, and the dispersion plates 33 are reset to the initial position. At this time, multiple angle blocks 31 are aligned with the angles between two adjacent dispersion plates 33. Then, the fourth motor 25 drives the third threaded rod 26 to rotate, causing the multiple angle blocks 31 to descend simultaneously. Since the angle blocks 31 correspond to the angles between two adjacent dispersion plates 33, the angle blocks 31 will push the alkaline neutralizing material stuck here to fall, thus ensuring the subsequent use effect of the dispersion plates 33 and also ensuring the addition amount of the alkaline neutralizing material.
