Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a skid-mounted integrated dosing device. Background Technology

[0002] During water treatment, potassium permanganate solution needs to be added to the water, and the water and potassium permanganate solution are stirred in a mixing tank. Potassium permanganate solution is used to oxidize and adsorb organic matter that causes odor due to oxygen. It can react with impurities in the water, such as ferrous iron, manganese, sulfur, cyanide, phenol, etc. Because the organic matter is oxidized, the generation of THIM, chlorophenol and other oxidative disinfection byproducts in the treated water is reduced, which greatly reduces the mutagenic activity of the water and achieves a good effect in removing iron and manganese.

[0003] The addition of potassium permanganate solution is generally done manually, which is not highly automated, has high labor costs, and low dosing accuracy. It is impossible to guarantee that the amount of solution added to the mixing tank is consistent each time, which may affect the quality of the final product. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: the addition of potassium permanganate solution is generally done manually, which is not highly automated, has high labor costs, and low addition accuracy. It is impossible to guarantee that the amount of medicine added to the mixing tank each time is consistent, which may affect the quality of the final product. Therefore, a skid-mounted integrated dosing device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A skid-mounted integrated dosing device includes a base plate. A mixing tank is fixedly mounted on the upper surface of the base plate via a support assembly. A rotating port is vertically opened on the upper surface of the mixing tank. A rotating rod is vertically rotatably mounted inside the rotating port. Multiple stirring rods are fixedly mounted on the surface of the rotating rod. A drive motor is fixedly mounted on the upper surface of the mixing tank via a connecting rod. The output shaft of the drive motor is fixedly connected to the rotating rod. A drug storage tank is fixedly mounted on the upper surface of the mixing tank. A hollow rod is fixedly mounted on the upper surface of the mixing tank. A piston block is slidably sealed inside the hollow rod. The hollow rod is connected to the drug storage tank via a drug inlet pipe. A drug outlet pipe connected to the hollow rod is fixedly mounted on the inner top wall of the base plate. Both the drug inlet pipe and the drug outlet pipe are equipped with one-way valves.

[0007] The top surface of the rotating rod is provided with a reciprocating thread, and a sliding plate is threaded onto it. A connecting rod is fixedly installed on the upper surface of the sliding plate. An installation rod is fixedly installed at the end of the connecting rod through a telescopic component. One end of the installation rod is fixedly connected to the upper surface of the piston block.

[0008] Preferably, the support assembly includes a mounting ring fixedly fitted onto the mixing tank and multiple support rods fixedly installed on the lower surface of the mounting ring, with the bottom end of each support rod fixedly connected to the upper surface of the base plate.

[0009] Preferably, the telescopic component includes a telescopic spring, the two ends of which are fixedly connected to the end of the connecting rod and the end of the mounting rod, respectively.

[0010] Preferably, scrapers are fixedly installed at the ends of multiple stirring rods located on the same longitudinal horizontal line, and the surface of the scrapers slides in contact with the inner wall of the mixing tank.

[0011] Preferably, a threaded rod is vertically and rotatably mounted on the upper surface of the hollow rod, and an L-shaped limiting plate is threaded onto the threaded rod. The bottom end of the limiting plate corresponds to the position of the upper surface of the piston block, and the limiting plate restricts rotation through a limiting component.

[0012] Preferably, the limiting component includes a limiting rod that is vertically fixedly installed on the upper surface of the mixing tank, and an mounting block is fixedly installed on the surface of the limiting plate, the mounting block being slidably sleeved on the limiting rod.

[0013] Preferably, the hollow rod is made of transparent material and has graduations on its surface.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Through the cooperation of the sliding plate, connecting rod, mounting rod, piston rod and hollow rod, the liquid medicine in the storage tank can be intermittently added to the mixing tank while the rotating rod drives multiple stirring rods to rotate. No manual addition is required, and the amount added each time is consistent, which improves the accuracy of the dosage, ensures the quality of the final product and reduces labor costs.

[0016] The movement distance of the piston block can be controlled by the cooperation between the threaded rod, the limiting plate and the telescopic spring, thereby adjusting the amount of medicine extracted each time. This makes the amount of medicine that can be supplied to the mixing tank not constant, thus improving practicality.

[0017] Multiple scrapers can slide and contact the inner wall of the mixing tank as the rotating rod drives multiple stirring rods to scrape off some of the medicine stains adhering to the inner wall of the mixing tank, ensuring that the medicine liquid put into the mixing tank can be completely mixed with water.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0024] Reference Figures 1-3 A skid-mounted integrated dosing device includes a base plate 1. A mixing tank 2 is fixedly mounted on the upper surface of the base plate 1 via a support assembly. The support assembly includes a mounting ring 14 fixedly sleeved on the mixing tank 2 and multiple support rods 15 fixedly mounted on the lower surface of the mounting ring 14. The bottom ends of the support rods 15 are fixedly connected to the upper surface of the base plate 1. A rotating opening is vertically formed on the upper surface of the mixing tank 2. A rotating rod 3 is vertically rotatably mounted inside the rotating opening. Multiple stirring rods 4 are fixedly mounted on the surface of the rotating rod 3. A drive motor 5 is fixedly mounted on the upper surface of the mixing tank 2 via a connecting rod. The output shaft of 5 is fixedly connected to the rotating rod 3. A medicine storage box 6 is fixedly installed on the upper surface of the mixing tank 2. A hollow rod 7 is fixedly installed on the upper surface of the mixing tank 2. A piston block 8 is slidably sealed inside the hollow rod 7. The hollow rod 7 is connected to the medicine storage box 6 through the medicine inlet pipe 9. A medicine outlet pipe 10 connected to the hollow rod 7 is fixedly installed on the inner top wall of the bottom plate 1. Both the medicine inlet pipe 9 and the medicine outlet pipe 10 are equipped with one-way valves. The direction of conduction of the one-way valve in the medicine inlet pipe 9 is from the inside of the medicine storage box 6 to the inside of the hollow rod 7. The direction of conduction of the one-way valve in the medicine outlet pipe 10 is from the inside of the hollow rod 7 to the inside of the mixing tank 2.

[0025] The top surface of the rotating rod 3 is provided with a reciprocating thread, and a sliding plate 11 is threadedly connected to it. A connecting rod 12 is fixedly installed on the upper surface of the sliding plate 11. An installation rod 13 is fixedly installed at the end of the connecting rod 12 through a telescopic component. The telescopic component includes a telescopic spring 16. The two ends of the telescopic spring 16 are fixedly connected to the end of the connecting rod 12 and the end of the installation rod 13, respectively. One end of the installation rod 13 is fixedly connected to the upper surface of the piston block 8.

[0026] The water to be treated is put into the mixing tank 2. Then, by starting the drive motor 5, the output shaft of the drive motor 5 rotates the rotating rod 3 and multiple stirring rods 4. At this time, the sliding plate 11 threaded onto the top of the rotating rod 3 will move vertically back and forth along with the connecting rod 12, the mounting rod 13, the telescopic spring 16, and the piston block 8. When the piston block 8 moves upward, the volume inside the hollow rod 7 increases and the pressure decreases. The medicine in the medicine storage tank 6 will enter the hollow rod 7 through the medicine inlet pipe 9. When the piston block 8 moves downward, the volume inside the hollow rod 7 decreases and the pressure increases. The medicine in the hollow rod 7 will enter the mixing tank 2 through the medicine outlet pipe 10. At the same time, the rotating rod 3 will mix the water and medicine in the mixing tank 2 along with the multiple stirring rods 4.

[0027] Multiple stirring rods 4 located on the same longitudinal horizontal line have scrapers 20 fixedly installed at their ends, and the surface of the scraper 20 slides in contact with the inner wall of the mixing tank 2.

[0028] Multiple scrapers 20 can slide and contact the inner wall of the mixing tank 2 during the rotation of the rotating rod 3 and the multiple stirring rods 4, thereby scraping off some of the medicine stains adhering to the inner wall of the mixing tank 2, ensuring that the medicine liquid put into the mixing tank 2 can be completely mixed with water.

[0029] A threaded rod 17 is vertically and rotatably mounted on the upper surface of the hollow rod 7. An L-shaped limiting plate 18 is threaded onto the threaded rod 17. The bottom end of the limiting plate 18 corresponds to the position of the upper surface of the piston block 8. The limiting plate 18 is restricted from rotation by a limiting component, which includes a limiting rod 19 vertically and fixedly mounted on the upper surface of the mixing barrel 2. An mounting block is fixedly mounted on the surface of the limiting plate 18 and slides onto the limiting rod 19.

[0030] By rotating the threaded rod 17, the limiting plate 18, which is threaded onto the threaded rod 17, will move vertically under the restriction of the limiting rod 19. When the rotating rod 3 rotates and the piston block 8 moves upward, when the upper surface of the piston block 8 abuts against the bottom end of the limiting plate 18, the piston block 8 is restricted by the limiting plate 18 and cannot move upward any further. If the sliding plate 11 continues to move upward, the telescopic spring 16 will be stretched, which can control the moving distance of the piston block 8, thereby adjusting the amount of liquid medicine extracted each time. This makes the amount of liquid medicine that can be supplied to the mixing tank 2 not constant, thus improving practicality.

[0031] The hollow rod 7 is made of transparent material and has scales on its surface. When adjusting the limiting plate 18 to move vertically, the limiting plate 18 can be quickly adjusted to the appropriate position by referring to the scales.

[0032] In this invention, the water to be treated is put into the mixing tank 2. Then, by starting the drive motor 5, the output shaft of the drive motor 5 rotates the rotating rod 3 and multiple stirring rods 4. At this time, the sliding plate 11 threaded onto the top of the rotating rod 3 will move vertically back and forth along with the connecting rod 12, the mounting rod 13, the telescopic component, and the piston block 8. When the piston block 8 moves upward, the volume inside the hollow rod 7 increases and the pressure decreases. The liquid medicine in the storage tank 6 will then enter the hollow rod 7 through the inlet pipe 9. When the piston block 8 moves downward, the volume inside the hollow rod 7 decreases and the pressure increases. The liquid medicine in the hollow rod 7 will then enter the mixing tank 2 through the outlet pipe 10. At the same time, the rotating rod 3 will mix the water and liquid medicine in the mixing tank 2 along with the multiple stirring rods 4. The liquid medicine in the storage tank 6 can be added to the mixing tank 2 intermittently without manual addition, and the amount added each time is consistent, which improves the accuracy of the dosage, ensures the quality of the final product, and reduces labor costs.

[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
