[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0034] Example 1
[0035] Reference Figure 1-7 , which is the first embodiment of the utility model, provides a silicon carbide drum drying machine, including a drum 1 and a material shaving assembly 2 arranged on the inner wall of the drum 1, a tube wall assembly 3 is arranged on the outer wall of the drum 1, and a connecting assembly 4 is sleeved on one end of the tube wall assembly 3, and a frame assembly 5 is arranged on the outer wall of the tube wall assembly 3; the material shaving assembly 2 includes a material shaving plate 21 arranged on the inner wall of the drum 1, the tube wall assembly 3 includes an insulation wall 31 arranged on the outer wall of the drum 1, and a connecting groove 34 is opened on the upper side of one end of the outer wall of the insulation wall 31, and an inclined plate 33 is arranged on the upper side of one end of the insulation wall 31 close to the connecting groove 34, and the connecting assembly 4 includes a sleeved outer wall of the insulation wall 31. The sleeve 41, a wedge block 43 is arranged inside the connecting groove 34, and a slide bar 44 is arranged on the upper end of the wedge block 43, and a spring 45 is sleeved on the outer wall of the slide bar 44, the drum 1 and the material copying assembly 2 are both made of silicon carbide, the inclined plate 33 and the wedge block 43 are both arranged as inclined surface structures, the inclined surfaces of the inclined plate 33 and the wedge block 43 are parallel to each other, the wedge block 43 is movably inserted in the connecting groove 34, the slide bar 44 is slidably inserted in the upper end of the sleeve 41, and a cavity matching with the wedge block 43 is opened on the inner wall of the upper end of the sleeve 41, the wedge block 43 and the cavity starting from the inner wall of the sleeve 41 are slidably connected, and the upper and lower ends of the spring 45 are fixedly connected to the sleeve 41 and the wedge block 43 respectively.
[0036] The tube wall assembly 3 further includes a positioning block 32 disposed at the lower end of the insulation wall 31 , and the connection assembly 4 further includes two groups of positioning grooves 42 stacked and opened at the lower end of the sleeve 41 , and the positioning block 32 is slidably inserted into one end of the positioning groove 42 .
[0037] The roller 1 and the material copying component 2 are made of high-purity silicon carbide powder and sintered at a high temperature of 2450°C. The product density is ≥2.70g / cm3, there is no metal impurity phase, and the product performance is stable. At the same time, the silicon carbide structure purity is high, and the raw material and the product can reach 99.9%. It can be used normally below 1650°C. The thermal conductivity of silicon carbide is equivalent to that of graphite, which can quickly conduct heat. The hardness is second only to diamond and cubic boron nitride. In addition, silicon carbide has no corrosion to strong acids and strong alkalis, and its corrosion resistance is better than tungsten carbide and aluminum oxide. The density is 2.7g / cm3, which is close to aluminum. Silicon carbide material can withstand rapid temperature changes, resist thermal shock, resist rapid cooling and heating, and has stable performance. It solves the problems of weak impact resistance, poor high temperature resistance, and poor thermal conductivity of the existing drum dryer drum. Since silicon carbide material has good thermal conductivity, an insulation wall 31 can be set on the outer wall of the drum 1. The insulation wall 31 is made of silicate material, which has a low thermal conductivity and good high temperature resistance, and can effectively reduce heat loss. The silicate insulation material also has good corrosion resistance and a long service life. In order to make better use of hot air during the drying process, the two sets of pipe walls can be combined. The heat preservation wall 31 can be quickly inserted into the sleeve 41 through the positioning block 32 at the lower end of the heat preservation wall 31 and the positioning groove 42 provided at the lower end of the sleeve 41. Due to the positioning effect of the positioning block 32 and the positioning groove 42, when the inclined plate 33 contacts the wedge block 43, the inclined surface of the inclined plate 33 cooperates with the inclined surface of the wedge block 43, so that the wedge block 43 drives the slide bar 44 to slide upward along the upper end of the sleeve 41. In this process, the wedge block 43 continuously compresses the spring 45. When the wedge block 43 leaves the inclined plate 33, the wedge block 43 slides along the outer wall of the heat preservation wall 31. When the wedge block When 43 reaches the connecting groove 34, under the reverse elastic force of the spring 45, the wedge block 43 is inserted into the connecting groove 34, thereby completing the installation of the insulation wall 31. When the insulation wall 31 needs to be disassembled, the slide bar 44 can be pulled upward to drive the wedge block 43 to leave the connecting groove 34. At this time, the insulation wall 31 can be quickly pulled out of the sleeve 41. Since the insulation wall 31 is fixedly sleeved on the outer wall of the drum 1, the installation and disassembly of the insulation wall 31 corresponds to the installation and disassembly of the drum 1. Multiple groups of drums 1 can be installed through multiple groups of connecting components 4, so that the hot air can be more fully utilized.

[0041] By setting the material shoveling plate 21 in a spiral shape, when the drum 1 rotates, the material inside the drum 1 can be continuously stirred and dispersed, thereby increasing the contact area between the material and the hot air and accelerating the drying. In addition, through holes 22 are evenly opened on the upper end of the material shoveling plate 21, and the through holes 22 allow hot air to flow between the material shoveling plates 21. The material can fall onto the baffle 23 through the through holes 22, and the baffle 23 can block the material to avoid accumulation of the material, so that the material is in more sufficient contact with the hot air.

After multiple groups of drums 1 are installed on the connecting assembly 4, in order to adapt to the base, the adjusting rod 52 can be used to slide the adjusting ring 53, change the position of the adjusting ring 53 on the adjusting rod 52, and the rotating groove 54 on the adjusting rod 52 corresponds to the base, and the device is placed on the base, so that the device can adapt to different bases.
