[0030] like Figure 5-6 As shown, this example can achieve the effect of initially crushing the raw quartz sand into different sizes according to needs.

[0031] The preparation system of high-purity quartz sand includes a rectangular frame 101, a mesh grid 105 is welded inside the rectangular frame 101, a plurality of protrusions 104 are evenly distributed on the upper side of the mesh grid 105, and two supporting legs 102 are connected to the left and right sides of the rectangular frame 101 by screws. The two supporting legs 102 can support the rectangular frame 101. When the raw quartz sand is placed on the mesh grid 105, the raw quartz sand is pressed, and the raw quartz sand can be broken by the plurality of protrusions 104. The broken raw quartz sand can fall from the mesh grid 105. The grid size of the mesh grid 105 can be set to different sizes as needed, and then the raw quartz sand can be initially broken into different sizes as needed.

[0032] like Figure 5-8 As shown, this example can achieve the effect of conveniently pouring quartz sand into the cylinder 201.

[0033] Since a cylinder 201 is arranged above the rectangular frame 101, an inlet 202 is arranged on the upper front side of the cylinder 201, and a conical edge 206 is arranged at the edge of the inlet 202, the cylinder 201 is used to load unbroken raw quartz sand, and the quartz sand can be conveniently poured into the cylinder 201 through the inlet 202 and the conical edge 206 thereon.

[0034] like Figure 7-8 As shown, this example can achieve the effect of driving the pressure seat 205 to move downward to press the raw quartz sand in the cylinder 201.

[0035] Since a rear frame 203 is welded to the upper rear side of the cylinder 201, a vertical column 204 driven by a hydraulic cylinder is vertically slidably connected to the rear frame 203, and a pressure seat 205 is fixed to the lower end of the vertical column 204. The hydraulic cylinder can drive the vertical column 204 on the rear frame 203 to slide vertically, thereby driving the pressure seat 205 to move downward to press the raw quartz sand in the cylinder 201, and then press the raw quartz sand onto the mesh grid 105, so that the raw quartz sand is initially crushed after passing through the mesh grid 105.

[0036] like Figure 5-8 As shown, this example can achieve the effect of improving the crushing efficiency of quartz sand.

[0037] Since the four sides of the upper side of the rectangular frame 101 are provided with bar holes 103, four flat rods 207 are welded to the lower end of the cylinder 201, and the four flat rods 207 are respectively inserted into the four bar holes 103. The four flat rods 207 can move horizontally on the four bar holes 103, so that the cylinder 201 can be translated relative to the rectangular frame 101 through the four flat rods 207. When the quartz sand in the cylinder 201 is pressed on the mesh grid 105, the cylinder 201 is driven to continuously translate, so that the quartz sand pressed on the mesh grid 105 is continuously rubbed on the mesh grid 105, rubbing the raw quartz sand, thereby improving the crushing efficiency of the quartz sand.

[0038] like Figure 5-8 As shown, this example can achieve the effect of translational swing friction on the raw quartz sand.

[0039] Since the four supporting legs 102 are respectively welded to the two bottom bars 401, a gantry 301 is welded between the front parts of the two bottom bars 401, a motor seat 303 is slidably connected to the gantry 301, the motor seat 303 is driven to slide by a hydraulic cylinder, a motor 1 302 is welded to the upper side of the motor seat 303, the output shaft of the motor 1 302 is connected to the middle part of the swing rod 304 by screws, the left and right ends of the swing rod 304 are hinged with hinged rods 307, the other ends of the two hinged rods 307 are respectively hinged to the left and right flat rods 207, the motor 1 302 can drive the swing rod 304 to swing, and then the hinged rod 307 can drive the left and right flat rods 207 to swing back and forth, and then drive the cylinder 201 to perform translational swing on the mesh grid 105, perform translational swing friction on the raw material quartz sand, and improve the crushing efficiency of the quartz sand.

[0040] like Figure 7-8 As shown, this example can achieve the effect of fixing the relative positions of the swing rod 304 and the cylinder 201.

[0041] Since threaded columns 306 are welded at both ends of the swing rod 304, a threaded column 306 is welded at the front of each hinge rod 307, and a positioning rod 305 is inserted into the threaded column 306 on each hinge rod 307. The other ends of the two positioning rods 305 are respectively inserted into the threaded columns 306 at both ends of the swing rod 304, and nuts are threaded on the threaded columns 306. The positioning rod 305 can be connected between the swing rod 304 and the hinge rod 307, thereby fixing the swing rod 304 and the hinge rod 307, and then fixing the relative position of the swing rod 304 and the cylinder 201.

[0042] like Figure 5-10 As shown, this example can achieve the effect of transporting the quartz sand after preliminary crushing.

[0043] Since the two bottom bars 401 are both provided with tracks 408, the two tracks 408 are both slidably connected with slides 407, and the upper parts of the two slides 407 are connected with a conical grinding disc 404 by screws, and the conical grinding disc 404 is located below the rectangular frame 101, and one of the bottom bars 401 is connected with a second motor 403 by screws, and the output shaft of the second motor 403 is connected with a screw rod 402, and the screw rod 402 is matched with one of the slides 407 by threads, and the crushed quartz sand falling from the mesh grid 105 will be received by the conical grinding disc 404, and then the screw rod 402 is driven to rotate by the second motor 403, thereby driving the two slides 407 to slide backwards along the two tracks 408 respectively, and then driving the conical grinding disc 404 to move backwards, and then the preliminarily crushed quartz sand is transported out.

[0044] like Figure 9-10 As shown, this example can achieve the effect of discharging the quartz sand after grinding on the conical grinding disc 404 from the discharge port.

[0045] Since a material drop opening is provided at the lower side of the conical grinding disc 404, a motor frame 405 is welded to the lower side of the conical grinding disc 404, and a motor three 406 is connected to the motor frame 405 by screws. A revolving door 409 is fixed to the output shaft of the motor three 406, and the revolving door 409 blocks the lower side of the material drop opening. The revolving door 409 is driven to open by the motor three 406, so that the quartz sand on the conical grinding disc 404 after grinding can be discharged from the material drop opening.

[0046] like Figure 9-10 As shown, this example can achieve the effect of driving the grinding block 501 to rotate and cooperate with the conical grinding disc 404 to grind the quartz sand.

[0047] Since a vertical frame 504 is welded to the rear of one of the bottom bars 401, an L-shaped frame 503 is vertically slidably connected to the vertical frame 504, and the L-shaped frame 503 is driven to slide by a hydraulic cylinder, and the upper part of the L-shaped frame 503 is connected to a motor 4 502 by screws, and a grinding block 501 is connected to the lower output shaft of the motor 4 502 by screws. When the conical grinding disc 404 moves backward to the lower side of the grinding block 501, the L-shaped frame 503 is driven to slide downward on the vertical frame 504, thereby causing the grinding block 501 to press against the quartz sand on the conical grinding disc 404, and then the grinding block 501 is driven to rotate by the motor 4 502, thereby driving the grinding block 501 to rotate and cooperate with the conical grinding disc 404 to grind the quartz sand.
