The left side of the drying barrel 5 is fixedly connected with a gear ring 11, and the left front end of the drying barrel 5 is rotatably connected with a gear 2 12. The right side of the gear 10 is fixedly connected with a stirring rod 13, which is convenient for stirring and mixing the materials. The gear 10 and the gear 2 12 are meshingly connected, so that when the gear 2 12 rotates, the gear 10 is driven to rotate, thereby driving the stirring rod 13 to rotate. The gear 2 12 and the gear ring 11 are meshingly connected.
[0032] The bottom end of the drying box 1 is fixedly connected to a water tank 14, which is conducive to the injection of condensed water. The left rear end of the water tank 14 is fixedly connected to a circulation pipe 15, which is conducive to the circulation of condensed water. The other end of the circulation pipe 15 is fixedly installed with a water pump 16, and the output end of the water pump 16 is fixedly connected to a heat dissipation pipe 17, which is convenient for the circulation of condensed water, thereby water cooling. The other end of the heat dissipation pipe 17 is fixedly connected to the right front end of the water tank 14, which is conducive to the formation of water circulation. The middle part of the right side of the water tank 14 is fixedly connected to a water injection pipe 19, which is convenient for the injection of condensed water. The other end of the water injection pipe 19 is threadedly connected to a water blocking cover 20, which is conducive to preventing the outflow of condensed water. The bottom end of the drying box 1 is fixedly connected to a heat insulation board 18, which is convenient for insulating the dryer and reducing the heating of the water tank 14. The top of the connecting box 2 A feed pipe 21 is fixedly connected to facilitate feeding, the middle outer side of the feed pipe 21 is fixedly connected to the middle top of the drying box 1, and discharge pipes 22 are fixedly connected to the left and right sides of the bottom end of the drying barrel 5 for discharging, and air outlet pipes 23 are fixedly connected to the left and right sides of the top of the drying box 1 for exhausting gas, and the front and rear sides of the drying box 1 are rotatably connected with opening and closing doors 24, and the upper and lower ends of the left side of the drying barrel 5 are fixedly connected with connecting plates 25.

When the drying barrel 5 rotates, the gear ring 11 is driven to rotate. Due to the meshing of the gear ring 11 and the gear 2 12, the gear ring 11 drives the gear 2 12 to rotate, and because the gear 2 12 is meshed with the gear 1 10, the gear 2 12 drives the gear 10 to rotate, so that the gear 10 drives the stirring rod 13 to rotate, which is convenient for stirring. The stirring rod 13 stirs the material inside the drying barrel 5, which is beneficial to increase the heating area of the cubic boron nitride, improve the uniformity of drying, reduce the phenomenon of secondary rework drying, improve the drying efficiency, and thus shorten the drying time. When cooling the material, condensed water is first injected into the water tank 14, and then the water pump 16 is started, so that the water pump 16 transmits the water flow inside the water tank 14 to the inside of the heat dissipation pipe 17 through the circulation pipe 15, and then the water flow inside the heat dissipation pipe 17 returns to the inside of the water tank 14, which is beneficial to form a water circulation, thereby forming a water cooling effect through the circulation of water flow, reducing the phenomenon of delaying the work progress due to natural cooling of the material, thereby helping to speed up the cooling time of the material and improve the cooling efficiency of the material.
