[0002] High-purity and highly hydrophobic quartz sand is widely used in high-tech fields such as electronics, optics, and chemical industry. Due to its strong hydrophobicity to water, special attention needs to be paid to the drying process of quartz sand. Common drying methods for high-purity and highly hydrophobic quartz sand usually rely on temperature control, air flow, and humidity control to ensure that the purity and functionality of the quartz sand are not affected.

[0003] The patent with the patent announcement number CN218722822U relates to a drying device for high-purity and highly hydrophobic quartz sand, including a main box body, a rotating assembly, and a drying assembly. A feed inlet is provided at the top of the main box body, and the quartz sand to be processed is introduced into the main box body through the feed inlet. The internal quartz sand is rotated by the rotating assembly, and then the quartz sand is dried by the drying assembly. The drying assembly includes a drying box, a heater, a heating pipe, a heating plate, a rotating shaft, and a cover plate. The drying box is arranged inside the main box body and directly below the feed inlet; through the mutual cooperation of the drying box, the heater, the heating pipe, the heating plate, the rotating shaft, the cover plate, the first motor, the stirring rod, and the stirring blades, the quartz sand inside the drying box can be dried to avoid moisture, and through the cooperation of the first motor, the stirring rod, and the stirring blades, the quartz sand inside the drying box can be turned over during drying.

The horizontal reciprocating movement of the sliding plate 16 drives the horizontal reciprocating movement of the material pushing rod 17. The horizontal reciprocating movement of the material pushing rod 17 can effectively push the quartz sand at the bottom of the inner wall of the feeding cylinder 5 into the drying cylinder 4, avoiding the accumulation of wet quartz sand at the bottom of the inner wall of the feeding cylinder 5 and improving the drying effect of the quartz sand.

[0034] A drying process for a drying device for high-purity and highly hydrophobic quartz sand uses a drying device for high-purity and highly hydrophobic quartz sand, including the following steps:

[0035] Step 1: The quartz sand is introduced into the interior of the feeding cylinder 5 through a conveying device, and the servo motor 2 and the transmission shaft 7 drive the gear 9 and the driven gear disk 10 to rotate, thereby realizing the rotation of the drying cylinder 4.

[0036] Step 2: The rotation of the transmission shaft 7 drives the driven shaft 12 to rotate through the speed regulating disk 13 and the fixed disk 14, and drives the sleeve 15 to reciprocate through the reciprocating thread groove. The reciprocating movement of the sleeve 15 can drive the sliding plate 16 and the sieve plate 18 to reciprocate.

[0037] Step 3: The reciprocating movement of the material pushing rod 17 can effectively push the quartz sand at the bottom of the inner wall of the feeding cylinder 5 into the drying cylinder 4.

[0038] Step 4: At the same time, the spiral feeding plate 11 can turn the quartz sand and carry the wet quartz sand above the sieve plate 18, and then fall above the sieve plate 18 under the action of gravity. At this time, the horizontal reciprocating movement of the sieve plate 18 can effectively disperse the wet quartz sand above the sieve plate 18.

[0039] When the present embodiment is working, quartz sand is introduced into the interior of the drying cylinder 4 through the feeding cylinder 5, and hot air is blown into the interior of the drying cylinder 4 through the air inlet pipe 51, and then the servo motor 2 is started, and the output end of the servo motor 2 rotates to drive the transmission shaft 7 to rotate, and the transmission shaft 7 rotates to drive the gear 9 to rotate, and the gear 9 rotates to drive the driven gear plate 10 to rotate, and the driven gear plate 10 rotates to drive the drying cylinder 4 to rotate, and the drying cylinder 4 rotates to drive the spiral feed plate 11 to rotate. When the spiral feed plate 11 rotates, the wet quartz sand can be effectively turned over, and the quartz sand is gradually guided to the direction of the discharge cylinder 6 and discharged. In this process, the rotation of the transmission shaft 7 drives the speed regulating disk 13 to rotate, and the rotation of the speed regulating disk 13 drives the fixed disk 14 to rotate, and the rotation of the fixed disk 14 drives the driven shaft 12 to rotate, and the rotation of the driven shaft 12 drives the sleeve 15 to move back and forth horizontally through the reciprocating spiral groove, and the sleeve 15 moves back and forth horizontally to drive the sliding plate 16 to move horizontally The sliding plate 16 reciprocates horizontally, and the sliding plate 16 reciprocates horizontally, driving the material removing rod 17 to reciprocate horizontally. The reciprocating horizontal movement of the material removing rod 17 can effectively push the quartz sand at the bottom of the inner wall of the feeding cylinder 5 to the inside of the drying cylinder 4, thereby preventing the moist quartz sand from accumulating at the bottom of the inner wall of the feeding cylinder 5, and improving the drying effect of the quartz sand. At the same time, the reciprocating horizontal movement of the sliding plate 16 drives the screen plate 18 to reciprocate horizontally. During the rotation of the spiral feeding plate 11, some moist quartz sand will be wrapped to the top of the screen plate 18, and then fall to the top of the screen plate 18 under the action of gravity. At this time, the reciprocating horizontal movement of the screen plate 18 can effectively shake off the moist quartz sand above the screen plate 18. In the process of the shaken quartz sand passing through the screen plate 18 and falling into the bottom of the drying cylinder 4, the moisture therein is removed under the action of hot air, thereby increasing the contact area between the quartz sand and the hot air, and preventing some quartz sand from agglomerating and thus reducing the drying effect.

[0040] See also Figures 1 - 6 On the basis of the above embodiment, in another embodiment of the present invention, a toggle device for raising the screen plate 18 to screen the agglomerated quartz sand is provided on the surface of the sliding screen plate 18, the toggle device comprises a support rod 201, a receiving plate 202, a lifting rod 203 and a receiving rod 204. During the lateral reciprocating movement of the screen plate 18, the reinforcing plate 19 is driven to move lateral, and the lateral movement of the reinforcing plate 19 drives the lifting rod 203 to move lateral.

The sieve plate 18 swings up and down to effectively throw up the quartz sand received on its surface, further increasing the contact area between the quartz sand and the hot air, and improving the drying efficiency of the quartz sand.

The lifting rod 203 is fixed and passes through the upper and lower walls of the sieve plate 18. The sieve plate 18 moves downward to squeeze the No. 1 spring 206 to contract. After the No. 1 spring 206 contracts, it returns to its original position and drives the sieve plate 18 to move upward.

[0042] The inside of the discharge barrel 6 is provided with a separation device for separating larger particles in the quartz sand, and the separation device includes a coarse material frame 211, a separation plate 212, a toggle plate 213, a cross bar 214 and a blocking plate 215. The toggle rod 17 moves to contact and squeeze the toggle plate 213 to move, and the movement of the toggle plate 213 can toggle the quartz sand above the separation plate 212. The coarse material frame 211 is fixedly passed through the inner and outer walls of the discharge barrel 6, and the separation plate 212 is slidably installed on the inner wall of the discharge barrel 6. Plate 213 is slidably installed above the separation plate 212, the cross bar 214 is fixedly installed on the inner wall of the discharge barrel 6, and the baffle plate 215 is fixedly installed below the separation plate 212. The baffle plate 215 is slidably connected to the inner wall of the discharge barrel 6. The movement of the toggle plate 213 can toggle the quartz sand above the separation plate 212, and sieve out the quartz sand that does not meet the standards through the separation plate 212, thereby avoiding the residue of large particles of quartz sand, thereby reducing subsequent processing costs and improving the purity of the quartz sand.

[0043] The separation plate 212 is arranged at an angle, and a material guide groove is provided on the surface of the toggle plate 213. The cross bar 214 slides through the left and right walls of the toggle plate 213. The substandard quartz sand accumulated on the top of the separation plate 212 will be discharged under the action of the coarse material frame 211, thereby avoiding the accumulation of substandard quartz sand on the surface of the separation plate 212 to cause blockage, thereby improving the separation effect and drying quality of the quartz sand and facilitating subsequent processing.

[0044] A No. 2 spring 216 is arranged between the toggle plate 213 and the inner wall of the discharge barrel 6, and the No. 2 spring 216 can drive the toggle plate 213 to reset. A No. 3 spring 217 is arranged between the blocking plate 215 and the inner wall of the discharge barrel 6, and the No. 3 spring 217 can drive the blocking plate 215 to reset.

[0045] When this embodiment is working: the sleeve 15 drives the reinforcing plate 19 to move horizontally during the lateral reciprocating movement, and the lateral movement of the reinforcing plate 19 drives the lifting rod 203 to move horizontally, and the lateral movement of the lifting rod 203 drives the receiving rod 204 to move horizontally, and the receiving rod 204 moves horizontally to contact the guide groove 205 on the surface of the receiving plate 202, and moves downward under the action of the guide groove 205, and the receiving rod 204 moves downward to drive the lifting rod 203 to move downward, and the lifting rod 203 moves downward to drive the sieve plate 18 to move downward, and the sieve plate 18 moves downward to squeeze the No. 1 spring 206 to contract, and the No. 1 spring 206 shrinks and resets to drive the sieve plate 18 to move upward, thereby realizing the up and down swing of the sieve plate 18, and the up and down swing of the sieve plate 18 can effectively throw up the quartz sand received on its surface, further increase the contact area between the quartz sand and the hot air, improve the drying efficiency of the quartz sand, and at the same time avoid excessive moisture quartz sand accumulating on the surface of the sieve plate 18 to affect the subsequent drying effect.

[0046] After drying, the quartz sand enters the interior of the discharge barrel 6 through the spiral feed plate 11, and the large particles of impurities therein are screened out under the action of the separation plate 212. In this process, the material-pickling rod 17 moves to contact and squeeze the poke plate 213 to move. The movement of the poke plate 213 can poke the quartz sand above the separation plate 212, and the quartz sand that does not meet the standards is screened out through the separation plate 212, thereby avoiding the residue of large particles of quartz sand, thereby reducing the subsequent processing cost and improving the purity of the quartz sand. At the same time, when the large particles screened out on the surface of the separation plate 212 gradually increase, the separation plate 212 The gradual reduction in separation effect will cause the quartz sand on its surface to gradually accumulate, and then the separation plate 212 will be driven downward by gravity. The downward movement of the separation plate 212 will drive the blocking plate 215 to move downward, and the blocking plate 215 will move downward to release the blockage of the coarse material frame 211. After the blockage is released, the non-standard quartz sand accumulated on the top of the separation plate 212 will be discharged under the action of the coarse material frame 211, avoiding the non-standard quartz sand from accumulating on the surface of the separation plate 212 and causing blockage, thereby improving the separation effect and drying quality of the quartz sand and facilitating subsequent processing.
