Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment technology, and in particular to an automatic dosing device for pure water treatment. Background Technology
[0002] Pure water treatment is a process that uses physical, chemical, and membrane separation technologies to remove dissolved salts, organic matter, microorganisms, particulate matter, and other impurities from water to obtain high-purity water. Its core objective is to make the water's conductivity, resistivity, total organic carbon, microbial content, and other indicators meet specific standards to satisfy the stringent water requirements of fields such as electronics, medicine, power, and laboratories.
[0003] A pure water treatment dosing device is a device used to add chemical agents during the pure water preparation process. Existing dosing devices typically use a dosing cylinder to add chemicals to the water tank for pure water treatment. However, the dosing cylinder cannot filter out the chemical residue in the chemical mixture. The residue will enter the metering pump or dosing pipeline with the chemical solution, causing the actual dosage to deviate from the design value. After the residue enters the pure water system, it will become a new source of pollution. Furthermore, it cannot mix the chemical particles in the dosing cylinder. Undissolved chemical particles settle or agglomerate due to gravity, resulting in concentration differences between the upper and lower layers of the dosing cylinder. Uneven mixing will lead to prolonged chemical reaction time or local residues, affecting the sterilization effect or causing side reactions. Utility Model Content

[0026] Example 1:
[0027] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides an automatic dosing device for pure water treatment, including a base plate 1. A water tank 2 and a chemical storage cylinder 6 are fixed to the top of the base plate 1. A connecting cylinder 3 is fixed to the inner wall of the water tank 2. A float plate 4 is slidably connected to the inner wall of the connecting cylinder 3. A measuring instrument 5 is installed at the bottom of the float plate 4. A cylinder cover 7 is installed at the top of the chemical storage cylinder 6. A filter assembly 8 and a mixing assembly 9 are respectively provided at the bottom of the cylinder cover 7. A chemical pump 10 is connected to the inner wall of the chemical storage cylinder 6. A chemical outlet pipe 11 is connected to the outlet end of the chemical pump 10. A measuring valve 12 is provided on the outside of the chemical outlet pipe 11.
[0028] Water tank 2 stores pure water to be treated and serves as the target container for adding the reagent. The reagent is stored in the storage cylinder 6. The float plate 4 floats up and down with the water level in water tank 2. The measuring instrument 5 installed at the bottom monitors the water level or water quality parameters in real time, providing feedback signals for automatic dosing. The filter assembly 8 intercepts drug residue or undissolved particles inside the storage cylinder 6, preventing them from entering the pump 10 or pipelines and avoiding blockage and equipment damage. The mixing assembly 9 stirs the liquid to promote the dissolution and mixing of the reagent, preventing sedimentation and clumping. The measuring instrument 5 and measuring valve 12 in this application have the same structure and working principle as the metering sensor and metering valve in application number 202420197479.1. The metering sensor and metering valve start working and the metering valve controls the corresponding amount to control the dosage of the reagent. This is prior art and will not be described in detail here. The pump 10 can draw the liquid from inside the storage cylinder 6 into the water tank 2, and one end of the outlet pipe 11 is connected to the top of the water tank 2.
[0029] The filter assembly 8 includes a connecting rod 81 fixed to the bottom of the cylinder cover 7, a frame 82 fixed to the bottom of the connecting rod 81, and a filter screen 83 for filtering the dregs of medicine fixed to the inner wall of the frame 82.
[0030] The frame 82 is supported by the connecting rod 81, and the filter screen 83 intercepts the residue or undissolved particles of medicine, preventing them from entering the medicine pump 10 or pipeline, thus avoiding blockage and equipment damage.
[0031] The mixing assembly 9 includes a first motor 91 fixed to the top of the cylinder cover 7, a rotating rod 92 fixed to the output end of the first motor 91, and a paddle 93 for mixing the medicine liquid fixed to the outside of the rotating rod 92.
[0032] The first motor 91 can drive the rotating rod 92 and the blade 93 to rotate, so that the blade 93 can stir the medicine liquid, promote the dissolution and mixing of the medicine, and prevent precipitation and clumping.
[0033] Example 2:
[0034] This is the second embodiment of the present invention, which is based on the previous embodiment.
[0035] Specifically, a mounting bracket 13 is fixed to the outside of the medicine storage cylinder 6, and multiple sets of mounting blocks 14 are fixed to the inner wall of the mounting bracket 13. A mounting plate 15 is fixed to the outside of the cylinder cover 7, and the mounting plate 15 and the mounting blocks 14 are fixed by bolts.
[0036] The mounting plate 15 can be fixed to the top of the mounting block 14 by bolts, thereby installing the cylinder cover 7 and facilitating the subsequent disassembly of the cylinder cover 7, which is convenient for maintenance and replacement of the internal components of the medicine storage cylinder 6.
[0037] Specifically, a handle 16 is fixed to the top of the cylinder cover 7, and the inner wall of the medicine storage cylinder 6 is connected to the feed inlet 17 and the drain outlet 18.
[0038] The handle 16 allows operators to easily open or close the cylinder cover 7 for adding medicine or maintenance operations. The inlet 17 is used to add medicine granules into the storage cylinder 6, and the drain 18 is used to discharge waste liquid.
[0039] Specifically, the inner wall of the medicine storage cylinder 6 is fixed with an installation plate 19 for installing the frame 82. The top of the installation plate 19 is fixed with multiple sets of locking rods 20, and the outer side of the locking rods 20 is engaged with the inner wall of the frame 82.
[0040] The frame 82 is snapped onto the outside of the lever 20, thereby installing the frame 82 on the top of the mounting plate 19 and facilitating the subsequent disassembly of the frame 82 and the filter screen 83.
[0041] Example 3:
[0042] This is the third embodiment of the present invention, which is based on the first two embodiments.
[0043] Specifically, a second motor 21 is fixed to the top of the water tank 2, a drive rod 22 is fixed to the output end of the second motor 21, and a stirring shaft 23 is fixed to the outside of the drive rod 22.
[0044] The second motor 21 can drive the drive rod 22 and the stirring shaft 23 to rotate, mixing the water and the agent in the water tank 2, ensuring that the agent is evenly dispersed and improving the treatment effect.
[0045] Specifically, a guide rod 24 is fixed to the inner wall of the connecting cylinder 3, and a sliding sleeve 25 is slidably connected to the outer side of the guide rod 24. The bottom of the sliding sleeve 25 is fixed to the top of the floating plate 4, and a spring 26 is provided on the outer side of the sliding sleeve 25.
[0046] The floating plate 4 floats up and down with the water level in the water tank 2. When the floating plate 4 floats up, it will cause the sliding sleeve 25 to slide on the outside of the guide rod 24, causing the spring 26 to contract. The measuring instrument 5 installed at the bottom monitors the water level or water quality parameters in real time, providing feedback signals for automatic dosing.
[0047] Specifically, the inner wall of water tank 2 is connected to an inlet 27 and an outlet 28, and an observation window 29 is provided on one side of water tank 2.
[0048] Pure water can be added to the water tank 2 through the inlet 27, and the treated pure water can be conveniently discharged through the outlet 28. Solenoid valves are installed on the outside of both the outlet 28 and the drain port 18.
[0049] During use, pure water to be treated is injected into the water tank 2 through the inlet 27, and the required drug particles or solution is added into the storage cylinder 6 through the feed inlet 17. Inside the storage cylinder 6, the first motor 91 of the mixing assembly 9 is activated, driving the rotating rod 92 and the paddle 93 to rotate, stirring the drug solution. This stirring action promotes the dissolution and mixing of the drug, preventing sedimentation and clumping, and ensuring uniformity of the solution. The filter screen 83 of the filter assembly 8 intercepts drug residue or undissolved particles, preventing them from entering the pump 10 or pipelines, thus avoiding blockage and equipment damage. The filter screen 83 is secured to the mounting plate 19 by the frame 82 and the clamping rod 20 for easy disassembly and cleaning. The float plate 4 inside the water tank 2 floats with the rising water level, and its top is connected to the guide tube via the sliding sleeve 25. The rod 24 is slidably connected to ensure the stable raising and lowering of the floating plate 4. The measuring instrument 5 at the bottom of the floating plate 4 monitors the water level or water quality parameters in real time, providing feedback signals for automatic dosing. When the feedback signal from the measuring instrument 5 determines that dosing is needed, the dosing pump 10 is started, drawing the liquid medicine in the storage cylinder 6 into the water tank 2 through the dosing pipe 11. The measuring valve 12 on the dosing pipe 11 precisely adjusts the flow rate of the liquid medicine to ensure accurate dosing. The measuring valve 12 and the measuring instrument 5 work together to form a closed-loop control system, realizing dosing as needed. After the liquid medicine enters the water tank 2, the second motor 21 is started, driving the drive rod 22 and the stirring shaft 23 to rotate, fully mixing the water and the medicine in the water tank 2. The stirring action ensures that the medicine is evenly dispersed in the water, improving the treatment effect.
