Description

Technical Field

[0001] This utility model relates to the field of steelmaking technology, and in particular to a sodium hypochlorite dosing device. Background Technology

[0002] Wastewater generated during steelmaking may contain pollutants such as oil, organic matter, and cyanide. Sodium hypochlorite, as a strong oxidant, can decompose these harmful substances and simultaneously disinfect the wastewater, ensuring that emissions meet standards.

[0003] Existing sodium hypochlorite dosing devices, such as the automatic sodium hypochlorite dosing device for water treatment disclosed in utility model patent application number 202421268960.1, mainly include a support assembly. A dosing component is fixedly connected to the inner wall of the support assembly. The dosing component includes a main pipe, a support plate fixedly connected to the outer wall of the main pipe, a storage tank fixedly connected to the outer wall of the support plate, a discharge pipe on the inner wall of the storage tank, and a water tank fixedly connected to the outer wall of the support plate. A pneumatic pump is installed at the top of the main pipe. In use, by activating and controlling the internal control structures of the storage tank and water tank, both are opened, discharging sodium hypochlorite solids and water into the main pipe. After the sodium hypochlorite solids collect and dissolve in the main pipe, the pneumatic pump is activated and controlled to expel air and pressurize the main pipe, discharging it into the water through a nozzle. The pipe design facilitates the discharge of sodium hypochlorite solids into the main pipe.

[0004] However, sodium hypochlorite is very unstable and easily decomposes under high temperature and light. Improper storage can easily lead to waste. Moreover, the contact time between sodium hypochlorite and water in existing dosing devices is relatively short, which may result in some sodium hypochlorite powder not coming into contact with water and sticking to the inside of the device, affecting the accuracy of the dosage.

[0005] In view of the problems existing in the above-mentioned prior art, it is necessary to research and design a new sodium hypochlorite dosing device to overcome the problems existing in the prior art. Summary of the Invention

[0006] To solve the above-mentioned technical problems, this utility model provides a sodium hypochlorite dosing device that not only seals and cools sodium hypochlorite powder to prevent its decomposition and volatilization, but also ensures that water and sodium hypochlorite are fully mixed to prevent sodium hypochlorite residue in the device and guarantee the accuracy of the dosage.

[0007] The technical means adopted in this utility model are as follows:

[0008] A sodium hypochlorite dosing device includes a support structure; it also includes a storage structure, a cooling structure, a conveying structure, and a dosing structure. The storage structure is installed on the support structure to store sodium hypochlorite; the cooling structure is installed on the support structure to cool the sodium hypochlorite; the conveying structure is installed on the cooling structure to convey the sodium hypochlorite; and the dosing structure is installed on the support structure to discharge sodium hypochlorite solution. The operator positions the dosing structure directly above a wastewater tank, stores sodium hypochlorite powder in the storage structure, and uses cooling water to cool the storage structure. When dosing is required, the conveying structure mixes the sodium hypochlorite and cooling water and conveys the mixture to the dosing structure. The dosing structure pressurizes and stirs the sodium hypochlorite solution and then dispenses the solution into the wastewater.

[0009] Preferably, the support mechanism includes a fixed seat, a support plate, an extension plate, two sets of hydraulic cylinders, and a fixed plate. The bottom end of the fixed seat is connected to the working surface, the bottom end of the support plate is connected to the top end of the fixed seat, the extension plate is slidably mounted on the support plate, both sets of hydraulic cylinders are connected and mounted between the support plate and the extension plate, and the fixed plate is mounted on the extension plate. The operator installs the fixed seat on the edge of the wastewater pool, and the two sets of hydraulic cylinders push the extension plate forward so that the fixed plate is positioned at a suitable position above the wastewater pool, facilitating subsequent chemical dosing.

[0010] Preferably, the storage mechanism includes a storage box, a hinge, a sealing cover, and a handle. The bottom of the storage box is connected to the top of the support plate. The storage box has an internal cavity. The hinge is installed on the storage box, the sealing cover is installed on the hinge, and the handle is installed on the sealing cover. The operator operates the handle to open the sealing cover, adds sodium hypochlorite into the cavity of the storage box, and then closes the sealing cover tightly to prevent light from shining into the cavity and reduce the decomposition of sodium hypochlorite.

[0011] Preferably, the cooling mechanism includes a water tank, a water pump, a pumping pipe, and a cooling pipe. The water tank is mounted on a support plate, the bottom of the water pump is connected to the top of the water tank, the pumping pipe is mounted on the water pump and communicates with the inside of the water tank, and the cooling pipe is mounted on the water pump and surrounds the outside of the storage tank. When the water pump is started, it draws cooling water from the water tank through the pumping pipe and delivers the cooling water to the cooling pipe to reduce the temperature around the storage tank and slow down the decomposition of sodium hypochlorite.

[0012] Preferably, the conveying mechanism includes a discharge pipe, a metering valve, a check valve, a control valve, and a conveying hose. The top end of the discharge pipe is connected to the bottom end of the storage tank, and the discharge pipe is also internally connected to the tail end of the cooling pipe. The metering valve and the check valve are installed on the discharge pipe, the control valve is installed at the tail end of the cooling pipe, and the conveying hose is internally connected to the cooling pipe. When feeding is required, the control valve is opened, and the metering valve discharges a measured amount of sodium hypochlorite from the cavity of the storage tank. The sodium hypochlorite dissolves in the cooling water and is conveyed to the dosing mechanism through the conveying hose. The check valve is used to prevent cooling water from entering the cavity of the storage tank.

[0013] Preferably, the dosing mechanism includes a feeding pipe, a dispensing tray, a motor, a rotating shaft, spiral blades, and three sets of stirring blades. The feeding pipe is mounted on a fixed tray and communicates with the inside of the conveying hose. The top of the dispensing tray is connected to the bottom of the feeding pipe, and multiple discharge holes are opened on the dispensing tray. The bottom of the motor is connected to the top of the feeding pipe. The rotating shaft is rotatably mounted inside the feeding pipe and longitudinally connected to the motor. The spiral blades are mounted on the rotating shaft, and all three sets of stirring blades are mounted on the rotating shaft. The conveying hose delivers sodium hypochlorite solution into the feeding pipe. The motor is started, and the motor drives the spiral blades to rotate through the rotating shaft. The spiral blades accelerate the delivery of the solution to the dispensing tray, pressurizing the solution. At the same time, the rotating shaft drives the three sets of stirring blades to rotate, agitating the solution while accelerating its discharge through the discharge holes of the dispensing tray.

[0014] Preferably, the inner walls of the feeding pipe and the material distribution tray are coated with a ceramic coating; by coating with a ceramic coating, the corrosion of the feeding pipe and the material distribution tray by the sodium chlorate solution can be slowed down, and the service life of the device can be extended.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This utility model provides a sodium hypochlorite dosing device. The operator positions the dosing mechanism directly above the wastewater tank and stores sodium hypochlorite powder in the storage mechanism.
