Description

Technical Field

[0001] This utility model relates to the technical field of dry powder dissolving and mixing devices, specifically to a fully automatic dry powder dissolving and dosing equipment. Background Technology

[0002] Wastewater treatment often involves chemical methods, including the use of flocculants and other chemicals to remove or reduce turbidity and suspended solids in viscous water, creating large aggregates that accelerate the settling of impurities and sludge. However, the dosage and solubility of flocculants in wastewater treatment still need improvement.

[0003] Chemical dosing devices are widely used in raw water, water supply, and wastewater treatment systems. They generally require the quantitative addition of chemicals. With the increasing application of automation, an automated dosing system is needed. When water treatment chemicals are in dry powder form, such as lime, polyaluminum, activated carbon powder, and coagulants / flocculators, the powder must be dissolved before quantitative dosing. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a fully automatic dry powder dissolving and dosing device. It features a simple structure, convenient operation, uniform mixing, and high efficiency. The device employs a continuous three-tank system (mixing tank, maturation tank, and storage tank) for dissolving, reducing equipment size and costs.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions:

[0006] A fully automatic dry powder dissolving and dosing device includes a frame. From right to left, the frame comprises a mixing tank, a maturation tank, and a storage tank. A dry powder dosing box connected to the mixing tank is mounted on the frame. A powder conveyor and a reagent mixer, connected by pipelines, are respectively installed on the side of the dry powder dosing box and the mixing tank. A water supply assembly connected by pipelines to the reagent mixer and the mixing tank is also located on the side of the frame. The water supply assembly includes a main water supply pipe, and water supply branch pipes are installed between the main water supply pipe and both the reagent mixer and the mixing tank. Each water supply branch pipe is equipped with a water supply branch valve.

[0007] Preferably, the main water supply pipe is equipped with a solenoid valve, the front end of the main water supply pipe is equipped with a main water supply valve, a water pressure detector is installed between the main water supply valve and the solenoid valve, and a flow meter is installed between the main water supply valve and the water supply branch pipe.

[0008] The water pressure gauge controls the inlet water pressure; when the pressure reaches a certain level, the medicine can be effectively dispersed through the water jet nozzle. The water jet nozzle uses high-pressure water to quickly wet the powder, ensuring it doesn't clump when it falls into the water. The flow meter controls the inlet water volume and adjusts the concentration.

[0009] Preferably, an auxiliary water supply pipe is provided between the water pressure tester and the flow meter, which is connected in parallel with the solenoid valve and connected to the main water supply valve, and a maintenance valve is provided on the auxiliary water supply pipe.

[0010] Preferably, the dry powder feeding box is equipped with a mixer on its side, which is connected to the bottom of the curing tank and the storage tank respectively. The mixer is equipped with stirring blades, which can effectively mix the medicine.

[0011] Preferably, the upper side of the frame is equipped with an electrical control box that connects the mixer, the powder conveyor, and the pharmaceutical mixer.

[0012] Preferably, the storage tank is equipped with an overflow pipe at its upper part and a liquid level sensor at its upper end. The liquid level sensor can control the amount of medicine in the storage tank.

[0013] Preferably, the mixing tank, maturation tank, and storage tank are all equipped with drain pipes at the bottom.

[0014] This invention can achieve the following effects:

[0015] This invention provides a fully automatic dry powder dissolving and dosing device, which, compared with existing technologies, features a simple structure, convenient operation, uniform mixing, and high efficiency.

[0021] 5. The size of the equipment has been reduced, thus lowering the cost.

[0022] 6. It can fully absorb and utilize the medicine, and remove all impurities. Attached Figure Description

[0027] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0028] Example: Figure 1 , Figure 2 and Figure 3 As shown, a fully automatic dry powder dissolving and dosing device includes a frame 1. From right to left, the frame 1 has a mixing tank 9, a maturation tank 11, and a storage tank 12. Each of the mixing tank 9, maturation tank 11, and storage tank 12 has a drain pipe 10 at its lower part. The storage tank 12 has an overflow pipe 3 at its upper part and a liquid level sensor 2 at its upper end. A dry powder dosing box 6 connected to the mixing tank 9 is mounted on the frame 1. A mixer 4 connected to the lower parts of the maturation tank 11 and storage tank 12 is located on the side of the dry powder dosing box 6. A powder conveyor 7 and a reagent mixer 13 connected by pipelines are located between the side of the dry powder dosing box 6 and the mixing tank 9. A water supply assembly 8 connected by pipelines to the reagent mixer 13 and the mixing tank 9 is located on the side of the frame 1. An electrical control box 5 connected by pipelines to the mixer 4, powder conveyor 7, and reagent mixer 13 is located on the upper side of the frame 1.

[0029] The water supply assembly 8 includes a main water supply pipe 17. A water supply branch pipe 19 is provided between the main water supply pipe 17 and the reagent mixer 13 and the mixing tank 9. A water supply branch valve 18 is installed on each branch pipe 19. A solenoid valve 16 is installed on the main water supply pipe 17. A main water supply valve 14 is installed at the front end of the main water supply pipe 17. A water pressure detector 15 is installed between the main water supply valve 14 and the solenoid valve 16. A flow meter 20 is installed between the main water supply valve 14 and the branch pipe 19. An auxiliary water supply pipe 21 is provided between the water pressure detector 15 and the flow meter 20, connected in parallel with the solenoid valve 16 and communicating with the main water supply valve 14. A maintenance valve 22 is installed on the auxiliary water supply pipe 21.

[0030] This fully automated continuous preparation and dosing system for powdered materials ensures uniform and dispersed feeding with a precision within 1%, from powder to prepared solution. The entire process is fully automated, safe, and continuous. Dry powder enters the powder mixer 13 from the dry powder dosing tank 6 via the powder conveyor 7. After wetting, it enters the mixing tank 9 for dilution to achieve the required concentration. The diluted solution flows through the maturation tank 11 and then into the storage tank 12. When the solution in the storage tank 12 is at a low level, the level sensor 2 triggers a level switch signal, restarting the solution preparation process. The controller calculates the dosage based on the required solution concentration, thus adjusting the powder dosage. This cycle stops when the solution in the storage tank 12 is at a high level. If the storage tank 12 is empty, the cycle restarts.

[0031] In summary, this fully automatic dry powder dissolving and dosing equipment features a simple structure, convenient operation, uniform mixing, and high efficiency. It employs a continuous three-tank system (mixing tank, maturation tank, and storage tank) for dissolving, reducing equipment size and costs.
