A grille plate 15 is fixedly installed below the second blower box 8. By starting the blower 14, it is possible to extract external air and convey it into the explosion-proof box 6, generating an upward flowing air current inside the explosion-proof box 6, which is beneficial to the heat dissipation inside the mixing tank 1.

[0028] Furthermore, a first blower box 7 is fixedly installed along one side of the refrigeration plate 11 on one side of the explosion-proof box 6.

[0029] Furthermore, central rods 19 are symmetrically and rotatably installed on both sides inside the mixing box 1. Above and below both sides of the central rod 19 on the right side, mounting plates 20 are symmetrically and fixedly installed respectively.

Then, the motor 3 is started to drive the driving rod 25 to drive the driving gear 26 to rotate. Through the meshing transmission of the gears, the transmission gear 24 rotates. Then, the central rod 19 rotates to drive the mounting plate 20, the scraper 21 and the stirring strip 22 to rotate, stirring the inside of the mixing tank 1 to mix different raw materials. At the same time, the large amount of heat generated by different carbide powders during the stirring process can be transferred to the explosion-proof box 6 through the heat-conducting plate 9 and the heat sink 10, so that the internal temperature of the mixing tank 1 can be dissipated in time. The first blower 14 is started and the refrigerating plate 11 is powered on, so as to extract external air and cool the air through the action of the refrigerating plate 11. During the upward flow of the low-temperature air, the heat sink 10 and the heat-conducting plate 9 can be quickly cooled, increasing the stability of heat dissipation in the mixing tank 1, which is beneficial to the stable mixing preparation of the multi-component composite carbide.
