Description

Technical Field

[0001] This invention relates to the field of quartz sand purification technology, and in particular to a device for producing and purifying refined quartz sand. Background Technology

[0002] Quartz sand is quartz particles produced by crushing and screening quartz stone. Quartz stone is a non-metallic mineral whose main mineral component is silicon dioxide (SiO2). Quartz sand can be classified according to quality into ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused quartz sand, and silica powder, etc. The SiO2 content and impurity content of various types of quartz sand are different. For example, the SiO2 content of ordinary quartz sand is generally not less than 90%, while the SiO2 content of high-purity quartz sand is as high as 99.9% or more.

[0003] Quartz sand purification uses "physical sorting + chemical purification" as its core logic. Through a combination of multiple processes, impurities (such as iron, aluminum, calcium, magnesium oxides and clay) are removed from quartz sand. Physical methods separate impurities that are visible to the naked eye or have large density differences, while chemical methods dissolve fine impurities or impurities within the crystal lattice, ultimately achieving an increase in SiO2 purity (from the natural 90%-98% to over 99.9%).

[0004] Existing quartz sand purification equipment has significant drawbacks in practical use, mainly as follows: On the one hand, in the crushing stage of quartz sand, the crushers used are mostly multi-stage combination modes with fixed speeds, lacking dynamic adjustment, which easily leads to uneven particle size. For example, it is difficult to accurately control the target particle size of 1-5mm, or the particle size exceeds the standard, resulting in impurities not being fully exposed. On the other hand, the crushed quartz sand needs to be filtered, and raw materials with excessive particle size need to be recycled and crushed again to facilitate impurity separation.

[0005] Therefore, a refined quartz sand production and purification device is needed. Summary of the Invention

[0017] This invention proposes a device for producing and purifying refined quartz sand. Compared with the prior art, the advantages of this invention are: 1. By setting up a drive gear set and a driven gear set, multi-stage speed control of the eccentric disc can be achieved, thereby controlling the vibration frequency of the moving jaw plate. After manually turning the throttle, the connecting rod will rotate. The concave limiting groove connected to the connecting rod will shift the position left and right, which will then drive the drive gear set to switch the position left and right. By utilizing the meshing structure of different gears in the drive gear set and the driven gear set, the speed of the driven gear set can be changed, thereby controlling the speed of the driven gear set, which indirectly changes the speed of the eccentric disc and the vibration frequency of the moving jaw plate, thus performing fine crushing of the quartz sand raw material between the moving jaw plate and the fixed jaw plate. 2. By setting a back plate, the jaw groove can be fully utilized, improving the crushing efficiency of quartz sand. When the fixed jaw plate and the jaw groove are squeezed against each other by the moving jaw plate, the bottom of the jaw groove suffers greater wear. After long-term use, the bottom of the jaw groove will wear too much, which will affect the crushing effect of quartz sand. At this time, the actual height of the fixed jaw plate can be changed. The bottom of the fixed jaw plate can be locked into the hook-shaped groove at different heights at the bottom of the back plate according to the actual wear of the jaw groove. At the same time, the back side of the fixed jaw plate is embedded in the convex groove of the back plate. The bolts are embedded in the vertical groove of the back plate to connect the back plate and the fixed jaw plate, thereby changing the jaw groove. 3. By setting up an upper connecting sleeve block, an upper driven sleeve block, and a compression spring, the vibration range of the moving jaw plate can be controlled while buffering the operation of the moving jaw plate, ensuring the overall stability of the device. When the moving jaw plate vibrates at high frequency, the moving jaw plate will transmit the displacement distance to the upper connecting sleeve block and the upper driven sleeve block through the upper crossbar connected to the back connecting block. The rotation and straightening structures of the upper connecting sleeve block and the upper driven sleeve block can effectively control the vibration amplitude of the moving jaw plate. At the same time, the setting of the compression spring can effectively buffer the power generated by the high-frequency vibration of the moving jaw plate, ensuring the stability of the overall crushing operation of the device. 4. By setting up a screening disc, raw materials with excessive particle size can be recycled and repeatedly crushed, which facilitates the separation of impurities. The quartz sand raw material crushed by the fixed jaw plate and the moving jaw plate will fall into the screening disc. At this time, the second motor drives the output shaft. By connecting the output shaft and the connecting sleeve plate, the inclined cylinder is driven to rotate. The screening disc connected to the top of the cylinder moves accordingly. The quartz sand fragments accumulated on the surface of the screening disc will seep through the trough at the edge and fall into the collection trough for recycling. The fragments that are not filtered out will be collected for repeated crushing. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-10 The present invention provides a technical solution: a refined quartz sand production and purification device, including a feed inlet 1, a detachable and installable pressure-resistant side plate 2 at the bottom of the feed inlet 1, and a detachable and installable support frame 3 on the side of the pressure-resistant side plate 2. The side bolts of the pressure-resistant side plate 2 are connected to the back plate 4. The surface of the back plate 4 is provided with a detachable jaw plate 5, and the surface of the jaw plate 5 is provided with a detachable jaw groove 6. The top side of the pressure-resistant side plate 2 is provided with a detachable driven rotating rod 7. The end of the driven rotating rod 7 is fixedly connected to an eccentric disk 8. The driven rotating rod 7 is connected to the center point of the eccentric disk 8. The moving jaw plate 9 is fixedly connected between the two sets of eccentric disks 8. The moving jaw plate 9 has an inclined structure design.

[0022] Furthermore, the top two sides of the back plate 4 are provided with convex grooves at equal intervals, the top two sides of the back plate 4 are provided with vertical grooves, and the bottom of the back plate 4 is provided with hook-shaped grooves at equal intervals. The bottom of the fixed jaw plate 5 is engaged in the hook-shaped groove at the bottom of the back plate 4, and the back side of the fixed jaw plate 5 is embedded in the convex groove of the back plate 4 in an engaged structure. The back plate 4 and the fixed jaw plate 5 are connected by bolts embedded in the vertical grooves. When the fixed jaw plate 5 and the jaw groove 6 are squeezed against each other with the moving jaw plate 9, the bottom of the jaw groove 6 suffers greater wear. After long-term use, the bottom of the jaw groove 6 will be worn too much, which will affect the crushing effect of quartz sand. At this time, the actual height of the fixed jaw plate 5 can be changed. The bottom of the fixed jaw plate 5 can be engaged in the hook-shaped grooves at different heights at the bottom of the back plate 4 according to the actual wear degree of the jaw groove 6. At the same time, the back side of the fixed jaw plate 5 is embedded in the convex groove of the back plate 4, and bolts are used to embed it in the vertical groove of the back plate 4, so that the back plate 4 and the fixed jaw plate 5 are connected, thereby changing the jaw groove 6.

[0023] Furthermore, the end of the pressure-resistant side plate 2 is provided with a detachable upper connecting plate 10, and the bottom of the upper connecting plate 10 is provided with a lower connecting plate 11 connected to the pressure-resistant side plate 2. The back side of the moving jaw plate 9 is sleeved with an upper crossbar 12 through a connecting block. The surface of the upper crossbar 12 is sleeved with an upper connecting sleeve block 13. The end of the upper connecting sleeve block 13 is provided with a detachable upper driven sleeve block 14. The end of the upper driven sleeve block 14 is connected to the side of the upper connecting plate 10. When the moving jaw plate 9 achieves high-frequency vibration, the moving jaw plate 9 will transmit the displacement distance to the upper connecting sleeve block 13 and the upper driven sleeve block 14 through the upper crossbar 12 sleeved with the back connecting block. By utilizing the rotation structure and straightening structure of the upper connecting sleeve block 13 and the upper driven sleeve block 14, the vibration amplitude of the moving jaw plate 9 can be effectively controlled.

[0024] Furthermore, a lower crossbar 15 is sleeved on the back side of the moving jaw plate 9 via a connecting block. A lower connecting sleeve 16 is fixedly connected to the surface of the lower crossbar 15. A compression spring 17 in a compressed state is provided at the end of the lower connecting sleeve 16. The end of the compression spring 17 is connected to the side of the lower connecting plate 11. The setting of the compression spring 17 can effectively buffer the power generated by the high-frequency vibration of the moving jaw plate 9 and ensure the stability of the overall crushing operation of the device.

[0025] Furthermore, a first motor 18 is provided on the top of the support base 3. The output end of the first motor 18 is provided with an active turntable 19. A transmission belt 20 is sleeved on the surface of the active turntable 19. The end of the transmission belt 20 away from the active turntable 19 is connected to a driven turntable 21. A connecting rod 22 passes through the midpoint of the driven turntable 21. One end of the connecting rod 22 is embedded in the interior of the pressure-resistant side plate 2 and is rotatably connected. The transmission belt 20 is used for power transmission, which can ensure that the quartz sand that is broken in the device splashes and does not affect the first motor 18. At the same time, the setting of the connecting rod 22 can ensure that the relative position of the driven turntable 21 remains unchanged. The rotational power is transmitted to the connecting sleeve 23 by the sleeve engagement of the connecting rod 22 and the connecting sleeve 23, which in turn drives the active gear set 24 to rotate.

[0026] Furthermore, a connecting sleeve 23 is sleeved at one end of the connecting rod 22, and the connecting rod 22 and the connecting sleeve 23 have a sliding structure. A drive gear set 24 is provided on the surface of the connecting sleeve 23, and a driven gear set 25 is meshed with the top of the drive gear set 24. Both the drive gear set 24 and the driven gear set 25 have three sets of gears. The three sets of gears in the drive gear set 24 are distributed in a 2:1:3 ratio, and the three sets of gears in the driven gear set 25 are distributed in a 2:3:1 ratio. A drive rod 26 is located at the midpoint of the side of the driven gear set 25. The end of the connecting rod 22 is connected to one end of the driven rotating rod 7; by utilizing the locking action of the connecting rod 22 and the connecting sleeve 23, the rotational power is transmitted to the connecting sleeve 23, which in turn drives the driving gear set 24 to rotate; the size matching of the three gears of the driving gear set 24 and the three gears of the driven gear set 25 can form a gear ratio, thereby forming a force-intensive combination and a force-saving combination. When the first motor 18 outputs stable power, the combination of different gear ratios can control the actual speed of the driven gear set 25, thereby changing the speed of the eccentric disk 8 and the vibration frequency of the moving jaw plate 9.

[0027] Furthermore, a concave limiting groove 27 is sleeved on the side of the central gear of the drive gear set 24. A connecting straight rod 28 is provided at the end of the concave limiting groove 27. A limiting cross rod 29 is sleeved on the surface of the connecting straight rod 28. The end of the limiting cross rod 29 is connected to the side of the pressure-resistant side plate 2. A positioning disc 30 is provided on the side of the limiting cross rod 29. The connecting straight rod 28 passes through the limiting cross rod 29 and the positioning disc 30. The upper half of the positioning disc 30 is provided with three sets of circular holes and slots distributed in an arc shape at equal intervals. A handle 31 is provided at the end of the connecting straight rod 28. A sleeve 32 is provided on the side of the handle 31. The sleeve 32 is embedded in the positioning disc 30. The upper half of the disc 30 has a locking structure in the circular slot. When the handle 31 is turned manually, the connecting rod 28 will rotate. The concave limiting groove 27 connected to the connecting rod 28 will shift its position to the left or right, which will then drive the drive gear set 24 to switch its position to the left or right. By using the meshing structure of the different gears of the drive gear set 24 and the driven gear set 25, the rotation speed of the driven gear set 25 will be changed, thereby controlling the rotation speed of the driven gear set 25. This indirectly changes the rotation speed of the eccentric disc 8 and the vibration frequency of the moving jaw plate 9, thereby performing fine crushing of the quartz sand raw material between the moving jaw plate 9 and the fixed jaw plate 5.

[0028] Furthermore, the bottom of the support frame 3 has a rectangular structure with four sets of collection troughs 33. The collection troughs 33 have a trapezoidal structure, and a motor housing 34 is located in the middle of the four sets of collection troughs 33. The crushed and qualified quartz sand will seep through the trough at the edge of the screening plate 43 and fall into the collection trough 33 for recycling. The motor housing 34 is designed to prevent the quartz sand that seeps through the trough at the edge of the screening plate 43 from entering the second motor 35 and affecting it.

[0029] Furthermore, the motor housing 34 is equipped with a detachable second motor 35. The output end of the second motor 35 is equipped with an output shaft 36. A connecting sleeve 37 is sleeved on the surface of the output shaft 36. The end of the connecting sleeve 37 is equipped with a detachable cylindrical column 38. The output shaft 36 and the cylindrical column 38 are in a rotating structure through the connecting sleeve 37. The second motor 35 drives the output shaft 36. By connecting the output shaft 36 and the connecting sleeve 37, the inclined cylindrical column 38 is driven to rotate at an incline. The screening disc 43 connected to its top moves accordingly. The quartz sand fragments accumulated on the surface of the screening disc 43 will seep through the trough at the edge and fall into the collection trough 33 for recycling.

[0030] Furthermore, an active sleeve 39 is provided at the midpoint side of the cylinder 38. A first driven crossbar 40 with a rotating structure is sleeved at the end of the active sleeve 39. A second driven crossbar 41, detachably mounted, is provided at both ends of the first driven crossbar 40. A connecting vertical plate 42 is rotatably connected to the center of the second driven crossbar 41 via a rotating shaft. The bottom of the connecting vertical plate 42 is connected to the side end of the motor housing. A screening disc 43 is engaged at the top of the cylinder 38. Slots are equidistantly provided at the edges of the screening disc 43. The active sleeve 39 provides support for the first driven crossbar 40 while ensuring the first... The driven crossbar 40 and the cylinder 38 rotate in tandem. At the same time, the second driven crossbar 41, which is connected to the first driven crossbar 40, rotates in tandem. The rotational support of the connecting vertical plate 42 ensures that the first driven crossbar 40 and the second driven crossbar 41 rotate in tandem. The arc-shaped block protruding between the first driven crossbar 40 and the second driven crossbar 41 provides a certain supporting force to the screening disc 43, preventing the screening disc 43 from tilting too much due to the excessive weight of the quartz sand raw material, which could cause the screening disc 43 to detach from the locking structure of the cylinder 38 and cause the screening disc 43 to tip over.

[0031] Working principle: This type of quartz sand production and purification device can be operated in the following ways; First, the quartz sand raw material is fed in through the feed inlet 1. The first motor 18 is turned on. The rotation of the first motor 18 drives the connecting rod 22 to rotate in tandem via the driving turntable 19, the transmission belt 20, and the driven turntable 21. The connecting rod 22 and the connecting sleeve 23 engage to transmit the rotational power to the connecting sleeve 23, which in turn drives the driving gear set 24 to rotate. At this time, through the meshing structure between the driving gear set 24 and the driven gear set 25, the driven gear set 25 rotates in tandem, driving the eccentric disk 8 to rotate. The moving jaw plate 9 vibrates to crush the quartz sand raw material between the moving jaw plate 9 and the fixed jaw plate 5. When the moving jaw plate 9 vibrates at high frequency, it will transmit the displacement distance to the upper connecting sleeve 13 and the upper driven sleeve 14 through the upper crossbar 12 connected by the back connecting block. The vibration amplitude of the moving jaw plate 9 can be effectively controlled by the rotation structure and straightening structure of the upper connecting sleeve 13 and the upper driven sleeve 14. The setting of the compression spring 17 can effectively buffer the power generated by the high frequency vibration of the moving jaw plate 9 and ensure the stability of the overall crushing operation of the device. Next, when the fixed jaw plate 5 and the jaw groove 6 are pressed against each other with the movable jaw plate 9, the bottom of the jaw groove 6 suffers greater wear. After long-term use, the bottom of the jaw groove 6 will be worn too much, which will affect the crushing effect of quartz sand. At this time, the actual height of the fixed jaw plate 5 can be changed. The bottom of the fixed jaw plate 5 can be locked into the hook-shaped grooves at different heights at the bottom of the back plate 4 according to the actual wear degree of the jaw groove 6. At the same time, the back side of the fixed jaw plate 5 is embedded in the convex groove of the back plate 4. The bolts are embedded in the vertical groove of the back plate 4 to connect the back plate 4 and the fixed jaw plate 5, thereby changing the jaw groove 6. Then, when the crusher needs to be adjusted at multiple speeds to precisely control the crushing accuracy, the throttle handle 31 can be manually turned. This will drive the connecting rod 28 to rotate. The concave limiting groove 27 connected to the connecting rod 28 will shift the position left and right. By using the locking action of the connecting rod 22 and the connecting sleeve 23, the driving gear set 24 will be driven to switch left and right positions, thereby driving the driving gear set 24 to rotate. The size matching of the three gears of the driving gear set 24 and the three gears of the driven gear set 25 can form a gear ratio, thereby forming a force-intensive combination and a force-saving combination. When the first motor 18 outputs stable power, the combination of different gear ratios can control the actual speed of the driven gear set 25, thereby indirectly changing the speed of the eccentric disc 8 and the vibration frequency of the moving jaw plate 9, thereby performing fine crushing of the quartz sand raw material between the moving jaw plate 9 and the fixed jaw plate 5. Finally, the crushed and qualified quartz sand will seep through the trough at the edge of the screening disc 43. At this time, the second motor 35 drives the output shaft 36. By connecting the output shaft 36 and the connecting sleeve 37, the inclined cylinder 38 is driven to rotate. The screening disc 43 connected to its top moves accordingly. The quartz sand accumulated on the surface of the screening disc 43 will seep through the trough at the edge and fall into the collection trough 33 for recycling.
