[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting up a shaking screen mechanism, the screen plate is shaken and screened to classify the quartz sand. By changing the connection of the connecting rod with the eccentric hole at different positions, the shaking amplitude of the screen plate can be adjusted to ensure the screening effect of the quartz sand.

[0015] 3. By setting up a dust removal mechanism, spray water is used to spray the dust-laden gas, reducing the dust content in the gas. Guided by multiple sets of air ducts, the dust-laden gas repeatedly impacts the water surface downwards. Under the action of inertial force, the dust comes into contact with the water surface, further improving the dust removal efficiency of the dust collection box. At the same time, the setting of multiple sets of air ducts can increase the residence time of the dust-laden gas in the dust collection box, increase the probability of the spray water coming into contact with the dust, and improve the dust removal effect.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figure 1 , Figure 3 and Figure 4As shown, a high-purity quartz sand production device includes a shell 1. A coarse sand box 101 is fixedly installed on the bottom left side of the shell 1. A coarse sand valve 101A is slidably connected to the left side of the coarse sand box 101. Larger quartz sand particles that have been screened fall into the coarse sand box 101. Opening the coarse sand valve 101A allows the separated coarse sand to be collected. A fine sand box 102 is fixedly installed on the bottom right side of the shell 1. A fine sand valve 102A is slidably connected to the right side of the fine sand box 102. Fine sand that has been screened falls into the fine sand box 102. Pulling up the fine sand valve 102A allows the fine sand to be collected. A feeding plate 103 is fixedly connected to the top of the shell 1, and a crushing mechanism 4 is fixedly installed at the bottom of the feeding plate 103. Quartz stone is placed on the feeding plate 103 and falls down under the action of gravity to contact the crushing mechanism 4 for crushing. A mounting rotating hole 104 is fixedly opened on the upper side wall of the shell 1, and a mounting boss 105 is fixedly installed on the inner wall of the right side of the shell 1. A shaking screen mechanism 2 is fixedly installed on the mounting boss 105. By setting the shaking screen mechanism 2, the screen plate 303A is shaken and screened to classify the quartz sand. By changing the connection of the connecting rod 204 with the eccentric hole 203A at different positions, the shaking amplitude of the screen plate 303A can be adjusted to ensure the screening effect of the quartz sand.

[0029] The bottom of the mounting boss 105 is fixedly equipped with a slide rail 106. A limiting component 3 is slidably mounted on the slide rail 106. By setting the limiting component 3, pushing the handle 302A inward can fix the screen plate 303A to the shaking screen mechanism 2, completing the screening operation of quartz sand. Pulling the handle 302A outward can move the screen plate 303A to the outside of the housing 1, making it convenient for workers to clean, disassemble and replace the screen plate 303A. A dust removal mechanism 5 is fixedly connected to the top of the housing 1. By setting the dust removal mechanism 5, spray water is used to spray the dust-laden gas to reduce the dust content in the gas. Guided by multiple sets of air ducts, the dust-laden gas repeatedly impacts the water surface downward. Under the action of inertial force, the dust comes into contact with the water surface, further improving the dust removal efficiency of the dust collection box 504. At the same time, the setting of multiple sets of air ducts can increase the residence time of the dust-laden gas in the dust collection box 504, increase the probability of the spray water coming into contact with the dust, and improve the dust removal effect.

[0030] like Figure 5As shown, the shaking screen mechanism 2 includes a drive motor 201, a reduction gearbox 202 fixedly connected to the drive motor 201, and a mounting boss 105 fixedly connected to the right side of the reduction gearbox 202. Eccentric wheels 203 are rotatably mounted on both sides of the reduction gearbox 202. Multiple sets of eccentric holes 203A are fixedly opened on the eccentric wheels 203, and the center distance between each set of eccentric holes 203A and the center of the eccentric wheel 203 is different. When the connecting rod 204 is connected and engaged with the eccentric wheels 203 at different positions, it will drive the limiting slide plate 301 to move with different amplitudes. The larger the amplitude, the faster the screening speed of the quartz sand; the smaller the amplitude, the better the screening effect of the quartz sand. The connecting rod 204 is rotatably connected to the eccentric holes 203A. The drive motor 201 drives the connecting rod 204 to move through the eccentric wheels 203. The other end of the connecting rod 204 is rotatably connected to the limiting slide plate 301, causing the limiting slide plate 301 to shake repeatedly.

[0031] like Figure 6 and Figure 7 As shown, the limiting component 3 includes a limiting slide plate 301, the right end of which is rotatably connected to the connecting rod 204. The limiting slide plate 301 is slidably connected to the slide rail 106. An L-shaped limiting rail 301A is fixedly provided on the limiting slide plate 301. The L-shaped limiting rail 301A includes a horizontal rail and a vertical rail, with the vertical rail located at the right end of the horizontal rail. A guide frame 302 is provided inside the limiting slide plate 301, and the outer wall of the guide frame 302 is slidably connected to the limiting slide plate 301. A handle 302A is fixedly connected to the left side of the guide frame 302. By providing the handle 302A, it is convenient for the operator to operate the guide frame 302, thereby adjusting the position of the screen plate 303A. The guide frame 302 has a guide rail 302B fixedly provided on its side wall. The guide rail 302B includes an inclined rail and a horizontal rail, with the inclined rail located at the right end of the horizontal rail. The horizontal rail has a fixed toothed groove 302C fixedly provided on its outer wall, located at the left side of the horizontal rail. The guide frame 302 has a frame 303 inside, and a screen plate 303A is installed on the frame 303. The screen plate 303A is connected to the frame 303 by bolts. The operator can remove the screen plate 303A from the frame 303 by removing the bolts, and then clean or replace the screen plate 303A to ensure the screening efficiency of the screen plate 303A.

[0032] A directional pusher plate 303B is fixedly installed on the upper part of the sieve plate 303A. By setting the directional pusher plate 303B, when the sieve plate 303A is repeatedly shaken under the push of the shaking sieve mechanism 2, the quartz sand on the sieve plate 303A is screened, and the large particles of quartz sand are continuously moved to the left side of the sieve plate 303A by the directional pusher plate 303B until they fall into the coarse sand box 101 at the bottom. The side wall of the frame 303 extends outward with a limiting rod 303C, and the guide rail 302B and the L-shaped limiting rail 301A are in sliding contact with the limiting rod 303C. When the guide frame 302 is pulled outward, the limiting rod 303C slides to the right of the guide rail 302B and gradually moves to the bottom of the vertical rail. As the guide frame 302 continues to be pulled outward, the limiting rod 303C slides on the horizontal rail until the end of the horizontal rail. At this time, the frame 303 and the screen plate 303A move to the outside of the housing 1, making it easy for the operator to disassemble the screen plate 303A. After the screen plate 303A is replaced, the operator pushes the guide frame 302 into the housing 1. When the limiting rod 303C moves to the rightmost side of the horizontal rail, the limiting rod 303C moves upward along the vertical rail under the pressure of the guide rail 302B and gets stuck in the horizontal rail, preventing the frame 303 from falling off the vertical rail.

[0033] like Figure 8 As shown, a sliding hole 303D is fixedly opened on the limiting rod 303C, and a locking block 303E is slidably connected to the sliding hole 303D. A compression spring 303F is fixedly connected to the locking block 303E, and the other end of the compression spring 303F is fixedly connected to the inner wall of the sliding hole 303D. A locking tooth is fixedly connected to the inner wall of the locking block 303E. When the locking tooth contacts the fixed tooth groove 302C, the relative displacement of the limiting slide plate 301 and the guide frame 302 in the horizontal direction can be locked. Locking block 303E maintains an inward sliding tendency under the push of compression spring 303F. By setting locking block 303E, it is locked into the vertical rail under the push of compression spring 303F, and the locking teeth contact the fixed tooth groove 302C, thereby locking the relative displacement of the limiting slide plate 301 and the guide frame 302 in the horizontal direction. This prevents the guide frame 302 from sliding outward due to inertia when the screen plate 303A shakes repeatedly, causing the limiting rod 303C to disengage from the horizontal rail. The movement of the limiting rod 303C on the horizontal rail can drive the screen plate 303A into the housing 1 for screening operations or drive the screen plate 303A out of the housing 1 for disassembly and cleaning operations. When the limiting rod 303C is on the vertical rail, the limiting slide plate 301 and the frame 303 achieve horizontal displacement locking, thereby transmitting the power of the shaking screen mechanism 2 to the screen plate 303A, causing the screen plate 303A to shake repeatedly.

[0034] like Figure 2 and Figure 9As shown, the dust removal mechanism 5 includes a suction hood 501, which is fixedly connected to the top of the housing 1. A baffle plate 501A is fixedly connected to the right side of the suction hood 501. The baffle plate 501A is made of rubber and will not obstruct the quartz stone from sliding down the feed plate 103. At the same time, the baffle plate 501A allows air from outside the housing 1 to enter the housing 1 through the opening in the middle of the housing 1 when the air pump 503 pumps dusty gas. This causes the dust near the screen plate 303A and the roller 403 to flow upward and be sucked into the dust collection box 504. If the baffle plate 501A is not provided, the air pump 503 will directly suck in clean air from the outside environment near the suction hood 501, and the dusty areas such as the screen plate 303A and the roller 403 will be difficult to clean by the dust removal mechanism 5. An air supply pipe 502 is fixedly connected to the top of the suction hood 501. The other end of the air supply pipe 502 is fixedly connected to a dust collection box 504. An air pump 503 is fixedly installed on the air supply pipe 502. Multiple sets of spray heads 504B are fixedly installed on the inner wall of the top of the dust collection box 504. The spray heads 504B are connected to a water pump through a water supply pipe, which can continuously spray water into the dust collection box 504 to absorb dust.

[0035] The top inner wall of the dust collector 504 is also fixedly connected to a first air duct 504A and a third air duct 504E. The bottom inner wall of the dust collector 504 is fixedly connected to a second air duct 504C. The first air duct 504A is inside the second air duct 504C, and the third air duct 504E is outside the second air duct 504C. A water level line 504D is fixedly provided on the second air duct 504C and the inner wall of the dust collector 504. The water level in the dust collector 504 is maintained at this height to avoid the water level being too high and submerging the first air duct 504A and the third air duct 504E, which would affect the airflow. It also avoids the water level being too low, which would prevent dust from contacting the water surface due to inertia when the air suddenly changes direction, thus affecting the dust cleaning effect. An air outlet 504F is fixedly opened on the side wall of the dust collector 504. After entering the dust collector 504, the dust-laden gas flows downward under the guidance of the first duct 504A. Then, under the guidance of the second duct 504C, the dust-laden gas quickly turns around and flows upward. During this sharp turn, the dust in the gas comes into contact with the water surface due to inertia, which improves the dust collection effect of the dust collector 504. Under the guidance of the third duct 504E, the dust-laden gas once again crashes downward into the water surface and is finally discharged from the outlet 504F.

[0036] The crushing mechanism 4 includes a second drive motor 401 and a crushing roller 403. The second drive motor 401 is fixedly connected to a reduction gearbox 402, which is fixedly connected to the outer wall of the housing 1. The output shaft of the reduction gearbox 402 is fixedly connected to the crushing roller 403, and the crushing roller 403 is rotatably connected to the mounting hole 104. The power of the second drive motor 401 is transmitted through the reduction gearbox 402, driving the crushing roller 403 to rotate, thereby realizing the crushing operation of quartz stone.

[0037] Work process:

[0038] 1. Place the quartz stone into the feeding plate 103, start the drive motor 401 to crush the quartz stone, and the quartz sand falls onto the screen plate 303A;

[0039] 2. Start the drive motor 201. The eccentric wheel 203 drives the limit slide plate 301 to shake repeatedly through the connecting rod 204. Small particles of quartz sand pass through the screen plate 303A and fall into the fine sand box 102. Large particles of quartz sand fall into the coarse sand box 101 at the bottom of the shell 1 under the repeated push of the directional push plate 303B, thus completing the grading operation of quartz sand.

[0040] 3. When it is necessary to replace the screen plate 303A or to clean the screen plate 303A, pull the locking block 303E outward so that the locking teeth disengage from the fixed tooth groove 302C. At this time, the guide frame 302 and the limit slide plate 301 resume automatic movement in the horizontal direction.

[0041] 4. Pull the guide frame 302 outward, and the limiting rod 303C of the frame 303 moves from the vertical rail to the horizontal rail. The frame 303 falls as a whole. Continue to pull the guide frame 302 outward, and the limiting rod 303C slides outward on the horizontal rail. The frame 303 drives the screen plate 303A to move to the outside of the housing 1. The operator can disassemble, replace and clean the screen plate 303A without having to crawl into the housing 1. The screen plate 303A can be processed in a small space.

[0042] 5. Push the guide frame 302 inward, and the limiting rod 303C slides inward on the horizontal rail. The frame 303 drives the screen plate 303A to move into the housing 1. Continue to push the guide frame 302 inward, and the guide rail 302B squeezes the limiting rod 303C onto the vertical rail. At this time, the frame 303 and the limiting slide plate 301 achieve relative displacement fixation in the horizontal direction. The shaking of the shaking screen mechanism 2 can be directly transmitted to the frame 303 and the screen plate 303A through the limiting slide plate 301. However, this structure is unstable. Once the guide frame 302 and the limiting slide plate 301 move horizontally, the limiting rod 303C can be disengaged from the vertical rail again, causing the screen plate 303A and the limiting slide plate 301 to move automatically.

[0043] 6. Under the push of the compression spring 303F, the locking block 303E contacts the fixed tooth groove 302C, and the side wall of the locking block 303E is inserted into the vertical rail, thereby realizing the locking of the guide frame 302 and the limiting slide plate 301 in the horizontal direction.

[0044] 7. Pull up the coarse sand valve 101A and the fine sand valve 102A to collect and process the coarse and fine sand.

[0045] This invention utilizes a swaying screening mechanism 2 to sway and screen the sieve plate 303A, thereby classifying the quartz sand. By changing the connection of the connecting rod 204 with different positions of the eccentric holes 203A, the swaying amplitude of the sieve plate 303A can be adjusted to ensure the screening effect of the quartz sand. A limiting component 3 allows the sieve plate 303A to be fixedly installed with the swaying screening mechanism 2 by pushing the handle 302A inward, completing the quartz sand screening operation. Pulling the handle 302A outward allows the sieve plate 303A to move into the housing 1. Externally, it facilitates workers to clean, disassemble, and replace the sieve plate 303A. By setting up a dust removal mechanism 5, spray water is used to spray the dust-laden gas, reducing the dust content in the gas. Guided by multiple sets of air ducts, the dust-laden gas repeatedly impacts the water surface downwards. Under the action of inertial force, the dust comes into contact with the water surface, further improving the dust removal efficiency of the dust removal box 504. At the same time, the setting of multiple sets of air ducts can increase the residence time of the dust-laden gas in the dust removal box 504, increase the probability of the spray water coming into contact with the dust, and improve the dust removal effect.
