[0027] Example 2

[0028] like Figure 1-4As shown, the mixing device housing 1 is made of steel. Support legs 2 are welded to the mixing device housing 1, and rubber pads are installed at the bottom of the support legs 2 to increase the stability of the device during operation. The solenoid valve 3 is bolted to the mixing device housing 1 for easy material discharge. The control box 4 includes a PLC controller and a touch screen. The touch screen displays temperature data detected by the first temperature sensor 9 and the second temperature sensor 15.
