Description

Technical Field

[0001] The utility model relates to the technical field of quantitative dosing, in particular to a water treatment quantitative dosing device. Background Art

[0002] For example, in a Chinese utility model patent with the patent publication number CN220907157U, the patent includes a dosing tank body. A driving motor I is fixedly installed at the top of the dosing tank body. A bevel gear II is fixedly connected to the top of a rotating rod. Moving grooves are opened on both sides of a support plate. A blanking plate is slidably installed between a pair of support plates in the moving grooves. A hydraulic expansion rod is fixedly installed below the blanking plate in a sliding groove. The bottom of the dosing tank body is fixedly connected with a medicine blocking plate. Blanking holes are opened on the surface of the medicine blocking plate. A quantitative gear is rotatably connected above the medicine blocking plate through a rotating shaft.

[0003] This patent can make the blocking time of the quantitative gear for each blanking hole the same through the uniform rotation of the quantitative gear on the surface of the medicine blocking plate. When the quantitative gear does not block the blanking hole, the discharge amount of medicine for each time of the blanking hole is also the same, realizing the automatic quantitative addition of medicine during water treatment.

[0004] However, when this patent discharges the medicine, some medicine will remain on the medicine blocking plate, and the medicine will be blocked by the quantitative gear. These medicines not only cannot be discharged, but also will adhere to the quantitative gear. After a long time, it is very likely to cause corrosion to the quantitative gear, thereby greatly reducing the service life of the quantitative gear. In view of this, we propose a water treatment quantitative dosing device. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The drawings are used to supplement the description in the text part of the specification, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the protection scope of the present invention.

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a water treatment quantitative dosing device, which includes a quantitative tank 1. An installation disk 2 is fixedly connected to the inner wall of the quantitative tank 1. A quantitative cylinder 3 is fixedly connected to the lower surface of the installation disk 2. A through groove 4 communicating with the inside of the quantitative cylinder 3 is opened on the upper surface of the installation disk 2. A first quantitative disk 5 is rotatably connected to the upper surface of the installation disk 2. A second through groove extending out of its lower surface is opened on the upper surface of the installation disk 2. A driving box 6 is fixedly connected to the inner wall of the second through groove. A second quantitative disk 7 is rotatably connected to the lower surface of the driving box 6. A feed port 8 extending into its interior is opened on the upper surface of the quantitative tank 1. Third through grooves 9 extending out of their lower surfaces are opened on the upper surfaces of the first quantitative disk 5 and the second quantitative disk 7. The third through grooves 9 on the first quantitative disk 5 and the second quantitative disk 7 are arranged in a staggered manner. An aggregate component is arranged on the inner wall of the quantitative tank 1. First, the water treatment drug mixture is transported into the interior of the quantitative tank 1 through the feed port 8 after being mixed with water. Subsequently, the drug mixture enters above the first quantitative disk 5 through the aggregate component. Since the third through groove 9 is provided on the first quantitative disk 5, the drug mixture will enter the interior of the quantitative cylinder 3 through the third through groove 9. And because the third through groove 9 on the lower second quantitative disk 7 is arranged in a staggered manner with the upper third through groove 9, the drug mixture will stay in the interior of the quantitative cylinder 3 at this time. At this time, control the first quantitative disk 5 and the second quantitative disk 7 to rotate synchronously. When the first quantitative disk 5 and the second quantitative disk 7 rotate one grid (the distance from one quantitative cylinder 3 to the adjacent next quantitative cylinder 3), that is, the third through groove 9 is aligned with the first subsequent quantitative cylinder 3. At this time, the quantitative cylinder 3 containing the drug mixture is closed both above and below, thus determining a unit of the drug mixture. At this time, continue to repeat the above steps to fill another quantitative cylinder 3. Subsequently, continue to rotate the first quantitative disk 5 and the second quantitative disk 7 one grid. At this time, the third through groove 9 on the second quantitative disk 7 is aligned with the first filled quantitative cylinder 3. At this time, the drug mixture in the quantitative cylinder 3 will be discharged through the lower third through groove 9, thereby quantitatively discharging a unit of the drug mixture. Through the above structure, not only can the addition of the drug mixture be completed quantitatively, but all the drives are enclosed, and the drug mixture cannot contact the internal mechanical structure, ensuring the safety of the mechanical structure, and there will be no problem of drug residue after discharge.

[0025] Further, the aggregate component includes a mounting ring 10 fixedly connected to the inner wall of the metering tank 1. A hopper 11 is fixedly connected to the lower surface of the mounting ring 10. A collection box 12 is fixedly connected to the lower surface of the hopper 11. A blanking port 13 corresponding to the metering cylinder 3 is provided on the bottom wall of the collection box 12. A conical ring 14 is fixedly connected to the upper surface of the mounting ring 10. A conical block 15 is fixedly connected to the upper surface of the drive box 6. A motor mounting sleeve 16 is fixedly connected to the inner wall of the drive box 6. A motor 17 is fixedly connected to the inner wall of the motor mounting sleeve 16. The output end of the motor 17 is fixedly connected to a first gear 18. A rotating shaft 19 is rotatably connected to the bottom wall of the drive box 6. A second gear 20 is sleeved on the outer surface of the rotating shaft 19. The second gear 20 is meshed with the first gear 18. The upper end of the rotating shaft 19 rotatably penetrates through the upper surface of the conical block 15. A conical connecting sleeve 21 is fixedly connected to the upper surface of the first metering plate 5. The conical connecting sleeve 21 is fixedly sleeved on the outer surface of the rotating shaft 19. The lower end of the rotating shaft 19 rotatably penetrates through the lower surface of the drive box 6. The lower end of the rotating shaft 19 is fixedly connected to the upper surface of the second metering plate 7. A connecting rod 22 is fixedly connected to the outer surface of the rotating shaft 19 outside the drive box 6. A connecting ring 23 is rotatably connected to the inner wall of the metering tank 1. A first cleaning plate 24 is fixedly connected to the lower surface of the connecting ring 23. A second rotating shaft 25 is fixedly connected to the lower surface of the second metering plate 7. A second cleaning plate 26 is fixedly connected to the outer surface of the second rotating shaft 25. A discharge port 27 extending out of the lower surface is provided on the bottom wall of the metering tank 1. After the drug mixture enters the interior of the metering tank 1, it first enters the interior of the collection box 12 through the hopper 11, and then enters the interior of the metering cylinder 3 through the blanking port 13 aligned with the upper third through groove 9. When driving the first metering plate 5 and the second metering plate 7 to rotate, the motor 17 cooperates with the first gear 18 to synchronously drive the second gear 20 to rotate. After the second gear 20 rotates, it synchronously drives the rotating shaft 19 to rotate. The rotating shaft 19 synchronously drives the upper first metering plate 5 to rotate by means of the conical connecting sleeve 21, and at the same time directly drives the lower second metering plate 7 to rotate by means of the rotating shaft 19. The conical connecting sleeve 21 can avoid drug residue and also protect the connection between the sealed rotating shaft 19 and the drive box 6. At the same time, when the rotating shaft 19 rotates, it will also synchronously cooperate with the connecting rod 22 to drive the connecting ring 23 to rotate. After the connecting ring 23 rotates, it synchronously drives the first cleaning plate 24 to rotate, and when the second metering plate 7 rotates, the second rotating shaft 25 can be used to drive the second cleaning plate 26 to rotate. Through the above structure, when quantitatively adding medicine to the drug mixture, the first cleaning plate 24 and the second cleaning plate 26 can be synchronously driven to rotate, so as to clean the easily sputtered areas by means of the first cleaning plate 24 and the second cleaning plate 26 and avoid drug residue.

[0026] Working principle: First, the water treatment drug is mixed with water and then conveyed into the interior of the metering tank 1 through the feed port 8. Subsequently, the drug mixture enters above the first metering disc 5 through the aggregate component. Since the third through groove 9 is provided on the first metering disc 5, the drug mixture will enter the interior of the metering cylinder 3 through the third through groove 9. And because the third through groove 9 on the lower second metering disc 7 is staggeredly arranged with the third through groove 9 above, the drug mixture will stay in the interior of the metering cylinder 3 at this time. At this time, control the first metering disc 5 and the second metering disc 7 to rotate synchronously. When the first metering disc 5 and the second metering disc 7 rotate one grid, that is, the third through groove 9 is aligned with the subsequent first metering cylinder 3. At this time, the metering cylinder 3 containing the drug mixture is sealed both above and below, thus determining a unit of the drug mixture. Then continue to repeat the above steps to fill another metering cylinder 3. Subsequently, continue to rotate the first metering disc 5 and the second metering disc 7 one grid. At this time, the third through groove 9 on the second metering disc 7 is aligned with the first filled metering cylinder 3. At this time, the drug mixture in the metering cylinder 3 will be discharged through the third through groove 9 below, thereby quantitatively discharging a unit of the drug mixture. After the drug mixture enters the interior of the metering tank 1, it first enters the interior of the aggregate box 12 through the aggregate hopper 11, and then enters the interior of the metering cylinder 3 through the blanking port 13 aligned with the third through groove 9 above. When driving the first metering disc 5 and the second metering disc 7 to rotate, the motor 17 cooperates with the first gear 18 to synchronously drive the second gear 20 to rotate. After the second gear 20 rotates, it synchronously drives the rotating shaft 19 to rotate. The rotating shaft 19 synchronously drives the upper first metering disc 5 to rotate by means of the conical connecting sleeve 21, and at the same time directly drives the lower second metering disc 7 to rotate by means of the rotating shaft 19. With the help of the conical connecting sleeve 21, drug residue can be avoided and the connection between the rotating shaft 19 and the drive box 6 can be protected. At the same time, when the rotating shaft 19 rotates, it will also synchronously cooperate with the connecting rod 22 to drive the connecting ring 23 to rotate. After the connecting ring 23 rotates, it synchronously drives the first cleaning plate 24 to rotate. And when the second metering disc 7 rotates, the second cleaning plate 26 can be driven to rotate by means of the second rotating shaft 25.

[0027] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
