Description

Technical Field

[0001] This utility model relates to the technical field of water treatment dosing devices, specifically a water treatment dosing device. Background Technology

[0002] The main function of a water treatment dosing device is to mix chemicals with aqueous solutions and transfer them to the appropriate equipment. The dosing device mainly consists of a chemical storage device, a drug delivery device, and an aqueous solution storage device. The chemical storage device stores the chemicals. When mixing chemicals, the drug delivery device introduces the chemicals into the aqueous solution storage device, so that the aqueous solution and chemicals are mixed. The mixed solution can be used to treat swimming pool water and medical wastewater.

[0003] Traditional dosing devices use stirring structures to accelerate the mixing of aqueous solutions and pharmaceuticals. Most traditional stirrers consist of a motor, stirring column, and stirring blades. While they can achieve mixing of pharmaceuticals and aqueous solutions, the mixing process is prone to localized clumping or component stratification due to the hygroscopicity and particle size differences of the pharmaceuticals, resulting in poor uniformity and low mixing efficiency between the pharmaceuticals and aqueous solutions. Utility Model Content

[0004] The purpose of this invention is to provide a dosing device for water treatment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water treatment dosing device, comprising a base, an aeration pump provided on one side of the inner wall of the base, and an air supply pipe inserted into the air outlet of the aeration pump, a drive motor provided on one side of the inner wall of the base, a dosing tank provided at the center of the top of the base, and an air injection pipe provided at the bottom of the inner wall of the dosing tank, one end of the air supply pipe being mounted on the top of the air injection pipe via a bearing, the bottom end of the air injection pipe being fixedly connected to the output end of the drive motor via a flat key, multiple stirring rods being welded to the outside of the air injection pipe, and multiple air holes being opened on the outside of the air injection pipe.

[0006] The stirring rod and the air injection pipe are interconnected, and multiple air holes are provided on one side of the outer wall of the stirring rod.

[0007] The top of the dosing tank is bolted with a tank cover, which is rotatably connected to the air injection pipe via a bearing. A water inlet pipe is inserted into the outer wall of one side of the top of the tank cover.

[0008] The outer wall of the top side of the can lid is provided with a medicine storage component, which includes an installation tube, the bottom end of which is inserted into the outer wall of the top side of the can lid.

[0009] The installation pipe is threaded to a material distribution component at its top end, and the material distribution component is threaded to a medicine storage cylinder at its top end.

[0010] The medicine storage assembly also includes a mounting cover, which is bolted to the top of the medicine storage cylinder. A rotary motor is bolted to the center of the top of the mounting cover, and a stirring rod is mounted on the output end of the rotary motor via a flat key. Stirring plates are welded to the outer walls on both sides of the stirring rod.

[0011] The material distribution component includes a material distribution cylinder, which is threadedly connected to the top of the mounting pipe. A rotating material distribution plate is installed inside the material distribution cylinder via a bearing. A material distribution motor is bolted to one end of the material distribution cylinder, and the output end of the material distribution motor is fixedly connected to one end of the rotating material distribution plate via a flat key. A connecting pipe is welded to one side of the outer wall of the material distribution cylinder, and one end of the connecting pipe is threadedly connected to the bottom end of the medicine storage cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the design of an aeration pump, air delivery pipe, air injection pipe, and air vent, allows for the mixing of aqueous solutions and pharmaceuticals in the dosing tank. Activating the aeration pump injects air into the air injection pipe via the air delivery pipe. The air is then discharged through the air vent on the air injection pipe. This forced airflow agitates the pharmaceutical particles, achieving thorough dispersion. This is particularly suitable for active ingredients with poor solubility or easy separation, significantly improving the uniformity of low-dose drugs and reducing the risk of clumping caused by uneven humidity in hygroscopic drugs. The included mounting cover, rotary motor, stirring rod, and stirring plate allow for controlled rotation of the tank at regular intervals, as the pharmaceuticals are temporarily stored inside. The motor starts at a set time, and the rotating motor drives the stirring rod to rotate. The stirring rod, along with the stirring plate, stirs the medicine inside the storage tank, breaking up the medicine and preventing clumping that could affect subsequent additions. When medicine is injected into the dosing tank via a feeding device, the feeding motor starts, and its output drives a rotating feeding plate. The periodic rotation of the feeding plate evenly distributes the medicine into different areas of the dosing tank, preventing localized accumulation or uneven concentration. Simultaneously, the rotation of the feeding plate prevents viscous medicine or particulate materials from clumping or clogging at the inlet of the installation pipe, ensuring a continuous and stable supply.

[0021] 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.

[0022] Please see Figure 1-6This utility model provides a technical solution: a water treatment dosing device, including a base 1, an aeration pump 8 (preferably HP-0300V oil-free silent vacuum pump) mounted on one side of the inner wall of the base 1 by bolts, and an air supply pipe 4 connected to the air outlet of the aeration pump 8; a drive motor 9 (preferably STP-42D2188) mounted on one side of the inner wall of the base 1 by bolts; a dosing tank 2 (made of metal pipe) mounted on the outer wall of the top of the base 1 by bolts at the bottom of the inner wall of the dosing tank 2; and an air injection pipe 7 (made of hollow pipe) welded to the outside of the air injection pipe 7 by a flat key. After the chemical addition is completed, the drive motor is operated. When motor 9 is started, it drives the air injection pipe 7 to rotate. The rotating air injection pipe 7 drives multiple stirring rods 11 to rotate. The stirring rods 11 stir the aqueous solution and medicine inside the dosing tank 2, so that the medicine and aqueous solution are mixed together. The stirring rods 11 also scrape the inner wall of the dosing tank 2 to prevent the medicine from sticking to the inner wall and affecting the mixing. Multiple air holes 10 are opened on the outside of the air injection pipe 7. During the mixing process, the aeration pump 8 is started. The aeration pump 8 injects air into the air injection pipe 7 through the air supply pipe 4. The air is then discharged through the air holes 10 on the air injection pipe 7. The discharged forced airflow will disturb the medicine particles inside the dosing tank 2 to achieve full dispersion of the medicine particles and improve the mixing effect and efficiency. The stirring rods 11 and the air injection pipe 7 are interconnected. Multiple air holes 22 are opened on one side of the outer wall of the stirring rod 11. Some of the air inside the air injection pipe 7 will flow into the stirring rod 11, and then the air inside the stirring rod 11 will be discharged through the air holes 22.

[0023] The top of the dosing tank 2 is bolted with a tank cover 3, which is rotatably connected to the air injection pipe 7 via a bearing. A water inlet pipe 5 is inserted into the outer wall of one side of the top of the tank cover 3, which allows workers to inject clean water into the dosing tank 2. A drug storage component 6 is provided on the outer wall of one side of the top of the tank cover 3. The drug storage component 6 includes an installation pipe 14, the bottom of which is inserted into the outer wall of one side of the top of the tank cover 3. A material distribution component 15 is threaded to the top of the installation pipe 14, and a drug storage cylinder 13 is threaded to the top of the material distribution component 15. The drug storage cylinder 13 temporarily stores a large amount of drug, which is in solid powder form.

[0024] The medicine storage assembly 6 also includes a mounting cover 16, which is bolted to the top of the medicine storage cylinder 13. A rotary motor 17 is bolted to the center of the top of the mounting cover 16. The rotary motor 17 is preferably an STP-43D2170. A stirring rod 18 is mounted on the output end of the rotary motor 17 via a flat key. Stirring plates 19 are welded to both outer walls of the stirring rod 18. The rotary motor 17 is started, and the started rotary motor 17 will rotate the stirring rod 18. The stirring rod 18 will stir the medicine inside the medicine storage cylinder 13 along with the stirring plates 19, so that the medicine inside the medicine storage cylinder 13 is dispersed, and the medicine is prevented from clumping and affecting the subsequent addition of medicine.

[0025] The distributing component 15 includes a distributing cylinder 20, which is threadedly connected to the top of the mounting pipe 14. A rotating distributing plate 22 is mounted inside the distributing cylinder 20 via bearings. The rotating distributing plate 22 has a cross-shaped cross section. A distributing motor 21 is bolted to one end of the distributing cylinder 20. The distributing motor 21 is preferably an STP-60D5012 model. When the distributing motor 21 is started, its output end will rotate the rotating distributing plate 22. The rotating distributing plate 22 rotates periodically, which will evenly distribute the medicine entering the dosing tank 2 to different areas, avoiding local accumulation or uneven concentration. The output end of the distributing motor 21 is fixedly connected to one end of the rotating distributing plate 22 via a flat key. A connecting pipe 23 is welded to one side of the outer wall of the distributing cylinder 20. The connecting pipe 23 facilitates the connection between the distributing cylinder 20 and the medicine storage cylinder 13. One end of the connecting pipe 23 is threadedly connected to the bottom end of the medicine storage cylinder 13.

[0026] Working Principle: When using this device, clean water can first be injected into the dosing tank 2 through the water inlet pipe 5. When the clean water reaches the appropriate level, the dispensing motor 21 is started. The output end of the dispensing motor 21 will rotate the rotating dispensing plate 22. The rotating dispensing plate 22 rotates periodically, which will evenly distribute the medicine entering the dosing tank 2 to different areas to avoid local accumulation or uneven concentration. At the same time, the rotating motor 17 can be started. The started rotating motor 17 will rotate the stirring rod 18, which will stir the medicine inside the storage cylinder 13 with the stirring plate 19, so that the medicine inside the storage cylinder 13 is dispersed, preventing the medicine from clumping and affecting the subsequent addition of medicine. After the medicine is added, the drive motor 9 is started. The drive motor 9 will drive the air injection pipe 7. The rotating air injection pipe 7 will cause multiple stirring rods 11 to rotate. The stirring rods 11 will stir the aqueous solution and medicine inside the dosing tank 2, so that the medicine and aqueous solution are mixed together. The stirring rods 11 will also scrape the inner wall of the dosing tank 2 to prevent the medicine from sticking to the inner wall of the dosing tank 2 and affecting the mixing. At the same time, during the mixing process, the aeration pump 8 will be started. The aeration pump 8 will inject air into the air injection pipe 7 through the air supply pipe 4. The air will then be discharged through the air hole 10 on the air injection pipe 7. At the same time, some of the air inside the air injection pipe 7 will flow into the stirring rods 11. The air that enters the stirring rods 11 will then be discharged through the air hole 12. The discharged forced airflow will disturb the medicine particles inside the dosing tank 2, so as to achieve full dispersion of the medicine particles and improve the mixing effect and efficiency.

[0027] 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.
