[0044] Specific implementation process: When using the utility model, firstly, the utility model is powered on, and the flow valve 22 of the feed port 2 is opened through the controller, and multiple reagents enter the tank body 1 from the feed port 2. The flow meter 21 of the feed port 2 measures the reagents. After the multiple reagents reach the preset reagent ratio, the controller sends a command to control the flow valve 22 to close, and the multiple reagents flow through the spray ball 23 through different feed ports 2 and are dispersed and sprayed from the small holes on the spray ball 23 to complete the preliminary mixing of the reagents. The liquid level gauge 8 on the side of the tank body 1 helps the user to read the height of the reagent liquid level in the tank body 1. After reaching the appropriate height, the motor 73 is started, and the movement of the power output end of the motor 73 is used to drive the stirring shaft 711 to move, and then drive the stirring blade 712 to stir the reagents, so as to achieve further mixing of the multiple reagents. If the required liquid needs to be heated, the controller sends a liquid level meter 8 provided on the inner periphery of the tank body 1 to the inner periphery of the tank body 1. Multiple heaters 11 issue heating instructions to heat the reagents. The thermocouple 12 arranged at the bottom of the stirring shaft 711 detects the reagent temperature in real time and sends temperature data to the controller through an analog-to-digital converter. The controller compares the temperature data with the preset temperature data. When the reagent temperature reaches the preset temperature, the controller issues an instruction to control the relay between the controller and the heater 11 to cut off the power and stop heating the reagent. During the mixing process, excess gas may be generated, causing the pressure in the tank body 1 to increase, thereby affecting the airtightness of the tank body 1 and increasing the danger of the tank body 1. The breathing port 3 can discharge the gas in the tank body 1. After the reagent mixing is completed, the container for containing the reagent can be connected to the discharge port 10, and the valve 101 of the discharge port 10 can be opened to release the configured reagent. The user can open the manhole 6 to check the inside of the tank body 1, and the explosion-proof test lamp 4 provides lighting for the user.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
