Description

Technical Field

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

[0002] In water treatment, mining, and energy production, it is often necessary to add granular chemicals (such as flocculants, neutralizing agents, and flotation agents) to water bodies or process flows to achieve water purification and process enhancement. Existing dosing systems mostly adopt the traditional structure of "chemical storage tank + delivery pipe + metering pump," which presents the following prominent problems in practical applications:

[0003] The problem of drug blockage / bridging is prominent: granular drugs are prone to "bridging" or blockage at the discharge port of the storage silo and in the conveying pipe due to moisture, agglomeration or adhesion to the inner wall of the conveying pipe, which leads to drug supply interruption. Manual disassembly and cleaning are required, which not only affects the efficiency of operation, but may also cause process interruption due to machine downtime.

[0004] Dosing accuracy is difficult to control: Traditional equipment relies on manual adjustment of valves or metering pump flow, which is affected by uneven particle size and changes in flowability of the agent, resulting in a large error in the dosage (usually exceeding ±5%), making it unsuitable for processes with strict requirements on agent concentration.

[0005] Low level of integration: The storage, conveying and mixing components of the existing equipment are mostly installed in a decentralized manner, requiring on-site pipeline connection and fixing, which results in a long construction cycle and inflexible movement, making it difficult to adapt to scenarios that require rapid deployment, such as field operations and temporary emergency situations.

[0006] High maintenance costs: Cleaning after blockage is difficult, some parts need to be disassembled frequently, which can easily cause wear and tear. At the same time, manual adjustment of dosing parameters requires professional personnel, resulting in high labor costs.

[0007] Therefore, developing a skid-mounted dosing device with anti-clogging, accurate metering, and integrated mobility characteristics has become a key requirement for solving the above-mentioned technical pain points. Utility Model Content

[0008] The purpose of this invention is to provide a skid-mounted dosing device to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A skid-mounted dosing device includes a mixing tank fixedly mounted on a skid base. A drain pipe is fixedly installed at the bottom of the mixing tank, and an electrically controlled valve is installed on the drain pipe. A top cover is connected to the top of the mixing tank via a flange. A stirring mechanism is fixedly installed on the top cover. A storage tank is fixedly mounted on the top of the top cover via a bracket. The bottom of the storage tank is conical, and a conveying square pipe is fixedly connected to the bottom end of the storage tank. A feeding pipe is connected to the bottom end of the conveying square pipe via an electrically operated shut-off valve. A through-hole is provided at the top of the top cover, through which the feeding pipe enters the mixing tank. A second rotating shaft and a first rotating shaft are rotatably mounted from top to bottom inside the conveying square pipe.

[0028] Please see Figures 1-3In this embodiment of the present invention, a skid-mounted dosing device includes a mixing tank 1 fixedly mounted on a skid-mounted base 2. The skid-mounted base 2 is welded from 10# channel steel, with anti-slip rubber pads welded to the bottom and multiple traction rings welded to the sides for easy forklift lifting or vehicle towing. A drain pipe 3 is fixedly installed at the bottom of the mixing tank 1, and an electrically controlled valve 4 is installed on the drain pipe 3. A top cover 5 is connected to the top flange of the mixing tank 1, and a stirring mechanism is fixedly installed on the top cover 5. The top of the top cover 5 is connected to a stirring mechanism via a stirring mechanism. A storage tank 11 is fixedly mounted on a bracket. The bottom of the storage tank 11 is conical, and a conveying square pipe 12 is fixedly connected to the bottom end of the storage tank 11. The inner walls of both the storage tank 11 and the conveying square pipe 12 are coated with polytetrafluoroethylene. The bottom end of the conveying square pipe 12 is connected to a feeding pipe 14 through an electric shut-off valve 13. The top of the top cover 5 has an opening 15, through which the feeding pipe 14 enters the mixing tank 1. A second rotating shaft 20 and a first rotating shaft 20 are rotatably mounted from top to bottom inside the conveying square pipe 12. A rotating shaft 16 is provided, and a cylindrical body 17 is fixedly sleeved on the outer wall of the first rotating shaft 16. Multiple grooves 18 are evenly arranged on the outer peripheral wall of the cylindrical body 17. A pipe body 19 is fixedly installed inside the material conveying square tube 12. The second rotating shaft 20 is located inside the pipe body 19. A fourth rotating shaft 24 and multiple third rotating shafts 22 are rotatably installed on the outer peripheral wall of the pipe body 19 via bearings. Multiple second stirring blades 25 are fixedly installed on the outer wall of the fourth rotating shaft 24 outside the pipe body 19. The top of each of the second stirring blades 25... Located inside the medicine storage tank 11, the third rotating shaft 22 is fixedly installed on the outer wall of the tube body 19 with multiple first stirring rods 23. The fourth rotating shaft 24 and the third rotating shaft 22 are both connected to the second rotating shaft 20 at one end inside the tube body 19. The second rotating shaft 20 is connected to the first rotating shaft 16 through a transmission mechanism. The outer wall of the material conveying square tube 12 is fixedly installed with a second stepper motor 27. The output shaft of the second stepper motor 27 is fixedly connected to one end of the first rotating shaft 16 or the second rotating shaft 20.

[0029] By adopting the above-mentioned solution, this utility model allows for the following operation: opening the electric shut-off valve 13 and then starting the second stepper motor 27 drives the first rotating shaft 16 and the second rotating shaft 20 to rotate. During the rotation of the second rotating shaft 20, the fourth rotating shaft 24 and multiple third rotating shafts 22 will be driven to rotate within the conveying square tube 12, thereby agitating the medicine particles entering the conveying square tube 12 and located in the bottom opening of the medicine storage tank 11 to avoid bridging or blockage, ensuring that the medicine particles fall smoothly within the conveying square tube 12. When the first rotating shaft 16 rotates, it will drive the cylinder 17 to rotate, causing the grooves 18 on the cylinder 17 to flip downwards after carrying the medicine particles, and allowing the medicine particles to enter the mixing tank 1 through the feeding pipe 14. The dosage can be controlled by the number of rotations required by the second stepper motor 27 to drive the first rotating shaft 16, making it more convenient to use.
