Apply agitation with different explosive raw materials.

Further, the stirring blade is a hollow structure, the hollow structure of the stirring blade is connected with the hollow structure of the rotating shaft, and the stirring blade is also provided with several ejection ports, which can further improve the sufficient contact between the material and the steam.

Further, the spout on the stirring blade is also provided with a filter to prevent the material in the stirring tank from entering the rotating shaft, which can ensure the high cleanliness of the hollow structure in the rotating shaft, so as to facilitate the stirring of the present invention. The device can be used for stirring with different explosive raw materials after cleaning.

Further, the rotating shaft extends into the bottom of the stirring tank and is connected with the sealed bearing box fixed on the bottom of the stirring tank.

Further, the inner diameter of the ejection port gradually increases from the inside to the outside, which facilitates the ejection of scattered high-pressure steam, facilitates the full contact of the steam with the explosive raw material, and reduces the phenomenon of concentrated steam injection.

Compared with the prior art, the advantages of the present utility model are:

1. The utility model communicates with the hollow structure of the rotating shaft through the rotary joint. When the transmission motor is started to drive the rotating shaft and the stirring blade to rotate, the incoming steam is ejected from the densely clothed outlet through the hollow structure of the rotating shaft, which is beneficial to the steam and stirring. The full contact of substances can not only improve the utilization rate of steam, save the loss of gas, etc., but also speed up the dissolution rate of explosive raw materials, which can greatly improve the dissolution rate of explosive raw materials, thereby improving the production efficiency of the entire production process;

2. The utility model switches on and off the solenoid valve installed at the steam inlet through PLC according to the set temperature. When it is necessary to store and keep warm in the stirring tank, it can also inject steam according to the temperature fed back by the temperature sensor for real-time adjustment, so as to adjust the temperature in real time. Adapting to the dissolving temperature of various raw materials is also conducive to saving steam and energy consumption. It is only necessary to set the dissolving temperature of various raw materials, and the utility model will automatically adjust the temperature, realize unmanned operation, and improve the degree of automation.
