At the same time, heat treatment can also change the crystal structure of quartz sand, enhance its hardness and wear resistance, eliminate residual stress in the sand, refine its internal structure, and improve its heat resistance and deformation resistance, thereby improving the durability of quartz products. In addition, through heat treatment, the thermal expansion coefficient, thermal conductivity and other performance parameters of quartz sand can also be adjusted to adapt to the application needs in different industrial scenarios and to meet the application needs of different industrial fields.

[0039] Further as Figure 3 , Figure 6 , Figure 7 and Fig. 9As shown, it is worth specifically explaining that the adjustment component 3 includes an inner cavity 303 opened inside the column roller 201, the inner cavity 303 is connected to the tube shaft 202, a U-shaped tube 301 is arranged inside the terminal sleeve 103, the two ends of the U-shaped tube 301 are respectively rotatably connected to the two ends of the tube shaft 202 and the two ends of the U-shaped tube 301 are respectively connected to the two tube shafts 202, a support rod 308 is arranged inside the terminal sleeve 103, the two ends of the support rod 308 are respectively fixed to the outer wall of the U-shaped tube 301 and the outer wall of the end sealing plate 106, a connecting tube 302 connected to the U-shaped tube 301 is fixed in the middle of the U-shaped tube 301, a nut sleeve 305 is fixed inside the end of the connecting tube 302 away from the U-shaped tube 301, and the nut sleeve 305 is internally threadedly connected to the threaded rod 306, and the thread The piston plate 304 is fixed on one end of the rod 306 located inside the connecting cylinder 302 and fits tightly with the inner wall of the connecting cylinder 302; the connecting cylinder 302 and the inner cavity 303 are filled with a certain amount of liquid, the liquid can be water or hydraulic oil, etc. During operation, by rotating the threaded rod 306, the threaded rod 306 drives the piston plate 304 to move in the connecting cylinder 302, so that the liquid in the connecting cylinder 302 is squeezed into the inner cavity 303 through the piston plate 304, so that the two column rollers 201 expand synchronously, so that the distance between the two column rollers 201 can be accurately adjusted according to the difference in particle size of the sand material, so that it is suitable for sand materials of different particle sizes, avoiding crushing of particles that are too fine or too coarse, effectively improving the application range of the overall equipment and improving the overall practicality.

[0040] Further as Figure 2 and Fig.10As shown, it is worth specifically explaining that the transfer assembly 4 includes a shaft 402 rotatably connected to the side wall of the closed end of the furnace body 5 away from its opening, the shaft 402 is arranged in the middle of the height direction of the furnace body 5, and two symmetrically distributed material guide plates 401 are fixed on the side of the shaft 402, and a large gear 403 is fixed at the end of the shaft 402. A servo motor 13 is fixed to the outer wall of the furnace body 5, and a small gear 404 meshing with the large gear 403 is fixed on the output end of the servo motor 13; in the sand material screening process, the servo motor 13 is started to work, and the output end of the servo motor 13 drives the small gear 404 to reciprocate in forward and reverse directions, and the small gear 404 and the large gear 403 cooperate to drive the material guide plate 401 to reciprocate within a certain angle range, thereby continuously The two reciprocating guide plates 401 will guide the sand flow leaking from the separation barrel 101 in different directions, guide the sand to spread to different positions in the heating chamber 8, improve the uniformity of sand laying, reduce the phenomenon of uneven sand accumulation or local vacancies, improve the space utilization rate in the heating chamber 8, and improve the uniformity of heating of the sand during the heating process.

At the same time, the rotating sub-drum 101 drives the multiple material-shifting plates 205 to rotate synchronously, so that the sand material in the sub-drum 101 is continuously delivered to the two column rollers 201 through the multiple material-shifting plates 205 to repeatedly crush the agglomerates of the sand material. When processing different sand materials, the threaded rod 306 is rotated, and the threaded rod 306 drives the piston plate 30 4 moves in the connecting cylinder 302, so that the liquid in the connecting cylinder 302 is squeezed into the inner cavity 303 through the piston plate 304, so that the two column rollers 201 expand synchronously, so that the distance between the two column rollers 201 can be accurately adjusted according to the difference in particle size of the sand material, so as to be suitable for sand materials of different particle sizes and avoid crushing too fine or too coarse particles; after the sand material sorting process is completed, the furnace door panel 10 is closed, and the electric heating tube 9 is energized, so that the sand material inside the heating chamber 8 is heated by multiple electric heating tubes 9 to perform heat treatment on the sand material.

Direct crushing and pulverizing not only greatly reduces the rigid impact on the crushing parts and prolongs the service life, but also effectively reduces the impurities mixed into the sand after being crushed, fully reduces the phenomenon of solid impurities being crushed and mixed into the sand, and further improves the purity of the sand; the adjustment component 3 is set to make the de-knot component 2 suitable for crushing sand of different types of particle sizes, avoiding crushing particles that are too fine or too coarse, effectively improving the application range of the overall equipment and improving the overall practicality; in the sand screening process, the sand flow leaking from the sand separation component 1 is guided in different directions by the transfer component 4, guiding the sand to spread more evenly into the heating chamber 8, reducing the phenomenon of uneven accumulation of sand or local vacancies, improving the space utilization rate in the heating chamber 8, and improving the uniformity of heating of the sand during the heating process. After the sand screening process is completed, the transfer component 4 is rotated to a horizontal position, and the material selection chamber 7 and the heating chamber 8 are separated by the transfer component 4, which greatly reduces the heat in the heating chamber 8 from entering the material selection chamber 7, and improves the protection of the components inside the material selection chamber 7.
