The output end of the motor is provided with a bevel gear; the cemented carbide is dried by a drying mechanism.

[0003] The above technical solution achieves drying by introducing hot air into the interlayer of the mixing barrel. However, directly discharging the hot air after filling the interlayer space will cause a waste of heat energy resources.

The lifting sealing plate 6 is provided in the interlayer of the mixing barrel 1, the rotating seat 9 is fixed on the upper end surface of the lifting sealing plate 6, the rotating block 10 is rotatably connected to the inside of the rotating seat 9, the height adjustment screw 11 is fixed at the center of the upper end surface of the rotating block 10, and a hot air introduction rod 8 is fixed inside the lifting sealing plate 6.

[0022] Further as Figure 1 、 Figure 2 and Figure 3 As shown, a heat-conducting chamber 4 is provided inside the mixing barrel 1 , and a sealing ring 7 is fixed to the lower end surface of the lifting sealing plate 6 .

[0023] Further as Figure 3 As shown, the lifting sealing plate 6 is slidably connected in the heat-conducting chamber 4 of the mixing barrel 1 , and the sealing ring 7 is in contact with the inner wall of the mixing barrel 1 .

[0024] This solution has the following working process: when in use, the cemented carbide slurry is mixed in the slurry chamber 5 of the mixing barrel 1 using a stirring mechanism. During the mixing process, the hot air pump group 3 is turned on, and the hot air of the hot air pump group 3 is introduced into the heat conduction chamber 4 of the mixing barrel 1 through the hot air inlet pipe 2. Before the hot air is introduced, the height adjustment hand wheel 12 is controlled to rotate the height adjustment screw 11 on the rotating seat 9. The height adjustment screw 11 is threadedly connected to the mixing barrel 1. In this way, the degree of rotation of the height adjustment screw 11 in the heat conduction chamber 4 can control the height of the lifting sealing plate 6, and the flexible adjustment of the height of the lifting sealing plate 6 can control the hot air filling space of the heat conduction chamber 4, so that the hot air filling space is adapted to the slurry height and the purpose of concentrating heat energy to promote efficient drying is achieved.

[0025] According to the above working process, it can be known that: adjusting the degree of screwing of the screw 11 in the heat conduction chamber 4 can control the height of the lifting sealing plate 6, and flexibly adjusting the height of the lifting sealing plate 6 can control the hot air filling space of the heat conduction chamber 4, so that the hot air filling space is highly adapted to the slurry and the purpose of concentrating heat energy to promote efficient drying is achieved.

[0026] Further as Figure 1 、 Figure 2 and Figure 4 As shown, the height adjustment screw 11 is threadedly connected to the upper end surface of the mixing barrel 1 , and a height adjustment hand wheel 12 is fixed to the end of the height adjustment screw 11 away from the rotating block 10 .
