Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a sodium chlorate reagent preparation device. Background Technology

[0002] Sodium chlorate solution is prepared using solid sodium chlorate through a dosing device. A search revealed Chinese patent CN222411868U, which discloses a sodium perchlorate production equipment with a mechanical stirring mechanism, relating to the field of sodium perchlorate production. The equipment includes a transparent glass shell, with a first funnel fixedly installed at the top. A funnel-shaped filter plate is fixedly installed at the bottom of the first funnel. The transparent glass shell contains a hollow cylinder, inside which a spiral auger is fixedly installed. A central column is fixedly installed in the middle of the spiral auger, and a conical component is fixedly installed at the top of the central column. This invention, by incorporating the hollow cylinder and spiral auger, allows the collection shell to continuously collect impurities during the reaction and spirally transport them to the upper surface of the funnel-shaped filter plate for filtration. Furthermore, the solution is also transported during this process, increasing the dissolution area of ​​chlorine in water, improving the efficiency of chlorine participation in the reaction, thereby increasing production, reducing worker workload, and enhancing the automation level of the equipment.

[0003] Currently, if the concentration of sodium chlorate is too high or too low, it will result in low reaction efficiency, waste of reagents, poor sterilization of the circulating water system, damage to the chlorine dioxide generator, and shorten its service life. Utility Model Content

[0004] To address the problem that existing preparation devices cannot safely and efficiently prepare solid sodium chlorate into solutions of the required concentration, this invention provides a sodium chlorate preparation device.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A sodium chlorate preparation apparatus includes a preparation tank, a preparation pump, and a preparation storage tank. A guide pipe is connected to the bottom of the outer wall of the preparation tank. One end of the guide pipe is connected to an inlet valve of the preparation pump. One end of the inlet valve is connected to the input end of the preparation pump. The output end of the preparation pump is connected to an outlet check valve. One end of the outlet check valve is connected to an outlet valve of the preparation pump. The outlet valve is connected to one side of the preparation storage tank. A level gauge is installed on one side of the outer wall of the preparation tank, with its detection end extending into the interior of the preparation tank. A level gauge is installed on the top surface of the preparation storage tank, with its detection end extending into the interior of the preparation storage tank.

[0007] Furthermore, a dispensing valve II is connected to the top of the outer wall of the dispensing box, and one end of the dispensing valve II is connected to the end of the dispensing pump inlet valve near the dispensing pump.

[0008] The beneficial effect of adopting the above-mentioned further solution is that it enables the circulation of the drug within the mixing tank. During the drug preparation process, if further mixing or concentration adjustment of the drug is required, the drug can be circulated between the mixing tank and the mixing pump by opening the mixing valve II, thereby improving the uniformity and accuracy of drug preparation.

[0009] Furthermore, a dispensing valve I is connected at the connection between the dispensing pump outlet check valve and the dispensing pump outlet valve, and the dispensing valve I is connected to the end of the dispensing pump inlet valve near the dispensing tank.

[0010] The beneficial effect of adopting the above-mentioned further solution is that it provides a path for the return of the reagent. During equipment commissioning or in case of abnormalities, the reagent can be returned to the inlet of the reagent mixing pump by opening the mixing valve I, facilitating the adjustment of the reagent delivery rate and pressure, and ensuring the normal operation of the equipment.

[0011] Furthermore, a water inlet solenoid valve is connected to one side of the outer wall of the medicine dispensing box.

[0012] The beneficial effect of adopting the above-mentioned further solution is that it can realize the automatic water addition function. When preparing sodium chlorate, by controlling the opening and closing of the water inlet solenoid valve, the amount of water added to the preparation tank can be precisely controlled, thereby accurately controlling the concentration of the reagent and improving the automation and accuracy of reagent preparation.

[0013] Furthermore, the medicine dispensing box and medicine storage tank are made of PVC material.

[0014] The beneficial effect of adopting the above-mentioned further solution is that PVC material has good corrosion resistance, can resist the corrosion of sodium chlorate agent, and extend the service life of the equipment.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This sodium chlorate preparation device uses a quantitative preparation method. When water is added to the specified mark on the liquid level gauge of the preparation tank, an interlock control is triggered, and the water inlet solenoid valve automatically closes, ensuring the accuracy of the concentration of the preparation each time.

[0017] This dosing device incorporates a guide pipe inside the dosing tank, allowing water to flow tangentially into the tank during dosing and mixing. This ensures thorough mixing of the medication, avoiding the problem of inability to stir when adding solid sodium chlorate and significantly improving dosing efficiency.

[0018] This dosing device is equipped with a low liquid level pump stop interlock in the dosing tank. When the liquid level drops, the dosing pump will automatically stop running, preventing damage to the equipment if the operator forgets to stop the pump and ensuring the safety of the sodium chlorate dosing process.
