Description

Technical Field

[0001] The utility model relates to the technical field of dosing devices, in particular to a sodium hypochlorite dosing structure for preventing oxidation corrosion. Background Art

[0002] Sodium hypochlorite is mainly used in many fields such as bleaching, industrial wastewater treatment, papermaking, textiles, pharmaceuticals, fine chemicals, sanitation and disinfection. It is generally believed that the bleaching property of sodium hypochlorite comes from its strong oxidizing property. The dosing device is a device with dosing, stirring and liquid conveying functions. The dosing device is used to convey sodium hypochlorite solution and is mainly used in many fields such as bleaching, industrial wastewater treatment, papermaking, textiles, pharmaceuticals, fine chemicals, sanitation and disinfection.

[0003] For example, the "Sodium Hypochlorite Dosing Device" with publication number CN217202213U includes: a drug storage tank, a metering pump, a manual valve, a delivery pipe, an electric control box, a frequency converter and a shock absorbing mechanism. The frequency converter is electrically connected to the electric control box and the metering pump respectively. The shock absorbing mechanism is installed under the manual valve and connected to the manual valve. The power of the metering pump is increased by the frequency converter, thereby increasing the pump speed of the metering pump, so that when the operator presses the dosing switch in the electrical control box during the process of adding sodium hypochlorite, the pressing time of the operator is reduced, thereby improving the dosing efficiency; at the same time, under the action of the shock absorbing mechanism, the manual valve can maintain the tightness of the connection with the pipeline during long-term use, and no leakage of sodium hypochlorite will occur, thereby avoiding the leakage of sodium hypochlorite after the metering pump is turned on due to the loose connection between the manual valve and the pipeline, thereby wasting data and causing environmental pollution.

[0004] Although the above-mentioned dosing device has certain advantages in dosing efficiency, it still has certain disadvantages:

[0005] When the above-mentioned dosing device is used to replenish the medicine storage tank, the dosing is performed through a pump control switch. Although the pump can control the time according to the ratio and the medicine needs to be added according to the ratio, the pump has a poor control effect on the ratio, which can easily cause the incoming ratio to deviate, and it takes time to adjust the ratio, which can easily affect the use effect of sodium hypochlorite.

[0027] Here’s how it works:

[0028] First, when in use, when the sodium hypochlorite solution in the liquid storage tank 1 is used up, it needs to be refilled through the liquid inlet pipe 4;

[0029] Second, when the liquid enters the regulating tank 51 through the liquid inlet pipe 4, it is blocked by the limiting block 54, and the motor 551 is started. The motor 551 rotates to drive the round rod 552 to rotate. When the round rod 552 rotates, it drives the driving wheel 553 to rotate.

[0030] Third, when the driven wheel 556 rotates, it drives the fixed rod 52 to rotate, and when the fixed rod 52 rotates, it drives the limiting block 54 to rotate. When the driving wheel 553 rotates, it drives the limiting disc 554 to rotate together. The limiting disc 554 limits the rotation angle of the driven wheel 556, so that it rotates a quarter of a turn, so that the limiting block 54 rotates synchronously. The number of turns of the limiting block 54 can be controlled according to the addition ratio to achieve the best mixing ratio.
