Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and more specifically, to a drug impregnation device. Background Technology

[0002] In the water treatment industry, various chemicals need to be added, and the dissolution and mixing process of these chemicals with water is crucial to their effectiveness. In existing technologies, when chemicals are mixed with water, problems such as drug accumulation and uneven dissolution often occur, thus affecting the drug's solubility and stability.

[0003] For example, during the addition of PAM (polyacrylamide), an impregnator is typically required. This ensures that the PAM powder can be quickly and evenly dispersed and dissolved in water, preventing clumping when added. Especially in a push-feed operation, continuous water and chemical supply is necessary, and a specific ratio must be maintained. Therefore, when the dosage needs to be minimized, the water-to-powder ratio must also be appropriate. Excessive water will result in insufficient dilution, preventing proper dissolution through friction. Thus, it's crucial to ensure each PAM powder particle has sufficient contact with water, while avoiding excessive water flow. Low flow rates can cause PAM to either float in the mixing tank or adhere to the impregnator surface due to a lack of water film, preventing the swirling and agitation of the water flow to disperse the powder. This results in undissolved particles during subsequent dissolution, affecting the uniformity of the solution and its effectiveness.

[0004] In addition, during the addition of other drugs, such as the mixing and dissolution of highly adsorbent activated carbon and water, it is also necessary to prevent uneven water flow. This can lead to uneven water flow on the inner surface of the cone, causing activated carbon to accumulate and form bridging in areas with no or insufficient water flow, ultimately resulting in blockage of the feed inlet. Therefore, to address the above technical problems, a drug impregnation device is proposed here. Utility Model Content

[0005] The purpose of this invention is to provide a drug impregnation device. Through an innovative tangential water inlet cone structure and a concave-convex structure on the outside of the cone, it ensures that the water can flow evenly along the entire inner surface of the cone at low flow rates, so that the drug can be evenly impregnated without local accumulation, thereby improving drug utilization and mixing uniformity while saving water.

[0006] This utility model is achieved through the following technical solution:

[0007] A drug immersion device includes a main body, which is a cylindrical structure open at both ends. A mounting plate is fixedly connected to the bottom of the main body, and a discharge port is opened on the lower side of the mounting plate.

The inner wall of the conical hopper has a periodic concave-convex structure, which is used to disperse water flow to form a uniform water film. A discharge pipe is fixedly connected to the lower side of the discharge port, and a water inlet mechanism is installed on the outside of the main body.

[0008] Preferably, the cone-shaped hopper has an open top and an outlet at the bottom, and is inverted cone-shaped.

[0013] Preferably, the mounting plate has mounting holes on its exterior, and the number of mounting holes is four sets arranged symmetrically.

[0014] The technical solution of this utility model has at least the following beneficial effects:

[0015] This invention proposes a drug impregnation device. First, by combining tangential water inlet with a concave-convex structure, it ensures uniform water flow and the formation of a water film even with small water volumes, effectively impregnating the drug and preventing drug accumulation on the cone surface. This significantly improves drug solubility and mixing efficiency. Second, the design simplifies the impregnation and mixing process, making the entire process smoother and reducing operational complexity. It also facilitates subsequent maintenance and upkeep.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 This utility model proposes a drug impregnation device, including a device body 1, which is a cylindrical structure with openings at both ends. A mounting plate 2 is fixedly connected to the bottom of the device body 1. A discharge port 3 is opened on the lower side of the mounting plate 2. A conical hopper 4 is fixedly connected to the upper side of the discharge port 3. The inclination angle of the conical hopper 4 is 40°-70°. The inner wall of the conical hopper 4 has a periodic concave-convex structure 5, which is used to disperse the water flow to form a uniform water film. A discharge pipe 6 is fixedly connected to the lower side of the discharge port 3. The discharge pipe 6 is connected to a mixing hopper or a dissolving tank at the rear end. The uniformly impregnated drug and water flow into the mixing hopper or tank through this pipe for further mixing or dissolving. A water inlet mechanism is installed on the outside of the device body 1.

[0022] The cone 4 has an open top and an outlet at the bottom, and is in the shape of an inverted cone. The inclination angle of the cone 4 can be set to 40°-70°.

[0023] The periodic concave-convex structure 5 is serrated. In this embodiment, the tooth spacing of the concave-convex structure 5 is 13.17 mm, the tooth height is 12 mm, and the number is 60 arranged in a ring. When the water flow rate is greater than 0.3 m3 / h, a water film can be formed evenly. The toothed structure on the concave-convex structure allows water to be evenly distributed on the outer surface of the cone 4. As an important component, the concave-convex structure has a unique function. Even when the flow rate is small, water can be preferentially drained through the bottom of the concave-convex structure. This characteristic ensures that when the device is slightly tilted or the water volume is insufficient, the water flow can still smoothly enter from the bottom of the concave-convex structure.

[0024] The water inlet mechanism includes a tangential water inlet hole 8 and a tangential water inlet pipe 9. The tangential water inlet hole 8 is located outside the main body 1 of the device, and the tangential water inlet pipe 9 is fixedly connected to the outside of the tangential water inlet hole 8. The tangential water inlet pipe 9 is fixedly connected to the main body 1 of the device. Water enters the cone 4 through the tangential water inlet pipe 9, forming a swirling flow.

[0025] The tangential water inlet pipe 9 coincides with the tangential line of the main body 1 at the tangential water inlet hole 8.

[0026] An overflow hole 7 is provided on the outside of the main body 1 of the device, and the overflow hole 7 is located directly above the tangential water inlet hole 8, wherein the overflow hole 7 is located 10-50mm above the tangential water inlet hole 8.

[0027] The mounting plate 2 has mounting holes 10 on its exterior, and there are four sets of mounting holes 10 arranged symmetrically.

[0028] The working principle of a drug impregnation device based on an embodiment is as follows: First, during the water inlet process, water enters the device body 1 through the tangential water inlet pipe 9. After entering the device body 1, it forms a swirling flow. Then, the water flow gradually rises and passes through the concave-convex structure 5, forming a uniform water film. This water film allows the water to flow evenly to the bottom even when the flow rate is not large. At this time, the bottom design of the concave-convex structure 5 ensures that when the water volume is small or the device is tilted, the water preferentially exits from the bottom of the concave-convex structure 5, thereby ensuring that the water can evenly enter the cone hopper 4 through the bottom of the concave-convex structure 5. Then, the drug falls from the top of the cone hopper 4. Due to the uniform distribution of the water film, the drug is evenly impregnated by the water when it comes into contact with the surface of the cone hopper 4. This design avoids drug accumulation on the surface of the cone hopper 4, allowing the uniformly soaked drug and water to enter the mixing hopper through the bottom outlet of the cone hopper 4 for further mixing and processing. The concave-convex structure 5 ensures that water is evenly distributed along the bottom of the structure at low flow rates, forming a uniform water film on the conical surface of the cone hopper 4. This uniformly wets the drug, preventing drug accumulation. Furthermore, the uniform wetting and mixing improves the solubility and mixing efficiency of the drug, enhances efficacy, reduces drug waste and processing time, and thus lowers the overall operating cost. In addition, the combination of tangential water inlet and the concave-convex structure 5 makes the entire wetting and mixing process simple to operate and easy to maintain, without the need for a complex control system.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
