[0002] Fused quartz is an amorphous (glassy) form of silicon oxide (quartz, silica). It is a typical glass with a long-range disordered atomic structure. It provides high operating temperature and low thermal expansion coefficient through three-dimensional structural cross-linking. The use of fused quartz materials in precision casting shells in developed countries such as the United States and Japan has been increasing year by year, especially in the surface layer of silica sol shells. It has achieved very effective results and has made great breakthroughs in the use and price ratio of zircon materials. It is currently an ideal engineering application material.

Through the preliminary crushing structure 6 and the secondary crushing structure 10, large quartz blocks can be more effectively crushed into fine particles during use, and the crushed quartz particles can be classified and collected, thereby improving crushing efficiency, reducing energy consumption, and ensuring product quality.

[0033] In some embodiments, the secondary crushing structure 10 includes a mounting plate 101 fixedly connected to the left side of the inner cavity of the protective frame 21, the left end surface of the mounting plate 101 is evenly rotatably connected to a crushing knife 102, the upper left end surface of the protective frame 21 is rotatably connected to a gear set 103, and the upper middle part of the left end surface of the mounting plate 101 is fixedly connected to a crushing motor 104 through a connecting rod, the left end surface of the middle gear of the gear set 103 is fixedly connected to the output end of the crushing motor 104, the left end surface of the crushing knife 102 The rotating shaft passes through the protective frame 21 and is respectively fixedly connected to each gear on the gear set 103.

[0034] Working principle: During operation, the external gas connecting pipe is threadedly connected to the connecting valve 94. At this time, the quartz raw material is placed on the upper end of the mounting structure 41. At this time, the raw material enters the preliminary crushing structure 6 under the action of gravity. At this time, the dustproof net 52 is pulled to place the placement rod in the inner cavity of the limit frame 531. At this time, the limit bolts 532 are rotated in sequence to connect and fix the placement rod.

[0035] The preliminary crushing structure 6 is thereby started, causing the output end of the crushing motor 61 to rotate, so that the crushing knife 63 in the middle of the inner cavity of the mounting frame 41 rotates, thereby causing the rear gear set 62 to rotate. At this time, since the gears in the rear gear set 62 are meshed with each other, the two adjacent gears rotate in opposite directions, thereby causing the crushing knife 63 to rotate in opposite directions, thereby performing preliminary crushing on the material.

[0036] At this time, the crushed material falls on the upper end surface of the guide frame 43 under the action of gravity. At this time, the unloading control structure 7 is started to rotate the output end of the unloading motor 71, so the rotating shaft 72 rotates, and then the material distribution plate 73 rotates with the rotating shaft 72 as the center, so that the crushed material is evenly dropped to the outer surface of the filter screen 23 in batches under the cooperation of gravity. At the same time, the gas injection structure 9 is started, so that the gas is transmitted to the injection pipe 91 through the gas pipe 93 after the pressurization of the connecting valve 101. At this time, the gas separates the crushed material due to mass through the exhaust groove 95 on the outer surface of the injection pipe 91. Since the front end surface of the rotating shaft 72 is connected to the driving gear 81, the driving gear 81 rotates, and then the toothed belt 83 rotates, so the transmission gear 82 rotates, so the connecting sleeve 92 rotates, so that the gas in the inner cavity of the injection pipe 91 is intermittently injected. At the same time, small particles in the material pass through the filter plate 23 into the inner cavity of the storage box 32, and at the same time, large volume materials enter the secondary crushing structure 10 through the filter plate 23 under the action of gravity.

[0037] At this time, the secondary crushing structure 10 is started, so that the output end of the crushing motor 104 rotates, so the gear set 103 rotates, and then the crushing knife 102 rotates. At the same time, since the adjacent gears in the gear set 103 rotate in opposite directions, the crushing knife 102 rotates in opposite directions, and the incoming material is subjected to secondary crushing. At this time, the crushed material enters the screening box 34 under the action of gravity. At this time, the particles in the inner cavity of the screening box 34 with a size smaller than the screening gap enter the storage box 32 under the action of gravity, so that the secondary crushed material is sorted according to the particle size.
