Technical Field
[0001] This utility model belongs to the field of quartz sand production technology and relates to a grinding machine for quartz sand. Background Technology
[0002] Quartz sand is quartz particles produced by crushing and screening quartz stone. Because quartz sand may contain non-structural impurities, it needs to be ground to separate these impurities and improve its purity; therefore, a grinding mill is required.
[0003] A purification device for high-purity quartz sand disclosed in Chinese patent CN222658794U includes a base plate, an mounting plate fixedly installed on one side of the base plate, a drive motor fixedly installed above the mounting plate, a crushing and stirring mechanism fixedly installed below the drive motor, a crushing barrel provided below the crushing and stirring mechanism, a barrel cover installed above the crushing barrel, and a grinding mechanism integrally connected below the crushing barrel.
[0004] This equipment crushes and grinds quartz stone by feeding it into a crushing cylinder, and the ground quartz stone is discharged through a sieve plate. However, unground quartz stone is prone to clogging the sieve plate, blocking the ground quartz stone and resulting in low grinding efficiency.
[0005] To solve the above problems, this utility model proposes a grinding machine for quartz sand. Utility Model Content
[0006] To address the problems existing in the background technology, this utility model proposes a grinding machine for quartz sand.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a shell, two grinding rollers are rotatably arranged inside the shell, a first inclined plate and a second inclined plate are fixedly arranged above the two grinding rollers inside the shell, and a feeding and discharging assembly is provided on the shell;
[0008] The outer shell is rotatably connected to an annular plate. Several material conveying components are evenly arranged on one side of the annular plate. The conveying components include a first rotating plate and a second rotating plate. A support member is provided on the annular plate. The support member abuts against a second inclined plate. One end of the second rotating plate is movably mounted on the support member. The second rotating plate abuts against the first inclined plate.
[0009] The distance between the inner wall of the outer shell and the outer surface of the annular plate gradually increases from top to bottom, and one end of the first rotating plate abuts against and slides against the inner wall of the outer shell.
[0010] Furthermore, two first motors are symmetrically fixedly connected to the first side of the outer shell. Each first motor corresponds to a grinding roller, and the first motor drives the corresponding grinding roller to rotate. One end of each of the first and second inclined plates is fixedly installed on the inner wall of the first side of the outer shell.
[0011] The other ends of the first and second inclined plates are fixedly connected to fixed plates, and the other ends of the two grinding rollers are rotatably connected to the fixed plates.
[0012] Furthermore, a turntable is rotatably connected to the inner wall of the second side of the outer casing. The turntable is cylindrical, and a fixing plate is disposed inside the turntable.
[0013] A second motor is fixedly connected to the second side of the outer shell. The output shaft of the second motor rotates through the second side of the outer shell and is fixedly connected to the turntable. The turntable and the annular plate are arranged coaxially.
[0014] Both the first rotating plate and the second rotating plate are rotatably connected between the turntable and the annular plate, and a torsion spring is provided between the rotating end of the first rotating plate and the turntable and the annular plate.
[0015] Furthermore, the support includes a connecting plate, which is fixedly connected between the turntable and the annular plate. Several sliding rods slide through the connecting plate at intervals, and one end of each sliding rod is fixedly connected to the same clamping plate. The clamping plate has an L-shaped cross-section, and one end of the second rotating plate is movably mounted on the clamping plate.
[0016] The other end of several of the sliding rods is fixedly connected to the same sliding plate, and the sliding plate abuts against the second inclined plate;
[0017] Each of the slide bars is fitted with a spring at one end near the slide plate. One end of the spring is fixedly connected to one side of the slide plate, and the other end of the spring is fixedly connected to one side of the connecting plate.
[0018] Furthermore, a discharge port is provided at the bottom of the outer shell, and a screen is fixedly installed inside the discharge port. The end of the first rotating plate is slidably disposed on the screen.
[0019] Furthermore, the feeding and discharging assembly includes a feeding pipe and a discharging pipe, the feeding pipe being fixedly inserted through the first side of the housing, and the end of the feeding pipe extending between the first inclined plate and the second inclined plate;
[0020] The discharge pipe is fixedly connected to the screen at the bottom of the outer casing.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] 1. The quartz sand grinder is equipped with a first rotating plate. A second motor drives the first rotating plate to rotate through a turntable and annular plate. The first rotating plate will scrape away the quartz sand that is blocked on the screen, reducing the quartz sand blockage and facilitating the rapid discharge of the ground quartz sand, thereby improving the grinding efficiency.
[0023] 2. The quartz sand grinding machine is equipped with a second rotating plate. As the first and second rotating plates gradually rotate upward, the quartz sand that has been shoveled away will fall onto the second rotating plate. Then, the second inclined plate will block the slide plate. The slide plate pulls the clamping plate through the slide rod, causing one end of the second rotating plate to leave the clamping plate. Then, the second rotating plate will rotate under the action of gravity, thereby dropping the quartz sand onto the grinding roller for further grinding, resulting in a good grinding effect.
[0024] 3. The quartz sand grinding machine is equipped with a first inclined plate. As the second rotating plate rotates, the first inclined plate will push the second rotating plate to rotate onto the clamping plate, so that the second rotating plate can transport quartz sand again, which has a high degree of automation.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] like Figures 1-6 As shown, the technical solution adopted by this utility model is as follows: A grinding machine for quartz sand includes a shell 1, and two grinding rollers 5 are rotatably arranged inside the shell 1. A circular plate 6 is fixedly connected to the inner wall of the shell 1, and one end of each of the two grinding rollers 5 is rotatably connected to the circular plate 6.
[0034] Two first motors 2 are symmetrically fixedly connected to the first side of the outer casing 1, with each first motor 2 corresponding to a grinding roller 5. The first motor 2 drives the corresponding grinding roller 5 to rotate. The output shaft of the first motor 2 passes through the outer casing 1 and the circular plate 6 and is fixedly connected to the corresponding grinding roller 5, so that the output shaft of the first motor 2 drives the grinding roller 5 to rotate. This allows the two grinding rollers 5 to cooperate in grinding the quartz sand.
[0035] Inside the outer casing 1, above the two grinding rollers 5, a first inclined plate 10 and a second inclined plate 16 are fixedly installed. The top ends of both the first inclined plate 10 and the second inclined plate 16 are inclined.
[0036] One end of the first inclined plate 10 and the second inclined plate 16 are both fixedly mounted on the inner wall of the first side of the outer casing 1, and one end of the first inclined plate 10 and the second inclined plate 16 are both fixedly connected to one side of the circular plate 6. The other end of the first inclined plate 10 and the second inclined plate 16 are both fixedly connected to a fixing plate 20, and the other ends of the two grinding rollers 5 are rotatably connected to the fixing plate 20. The two ends of the grinding rollers 5 are positioned.
[0037] The first inclined plate 10, the second inclined plate 16, the circular plate 6, and the fixed plate 20 are combined to form a funnel, so that the quartz sand can fall between the two grinding rollers 5, making the grinding more thorough.
[0038] A turntable 19 is rotatably connected to the inner wall of the second side of the outer casing 1. The turntable 19 is cylindrical, and a fixing plate 20 is disposed inside the turntable 19. The rotation of the turntable 19 will not affect the fixing plate 20.
[0039] A second motor 4 is fixedly connected to the second side of the outer casing 1. The output shaft of the second motor 4 rotates through the second side of the outer casing 1 and is fixedly connected to the turntable 19. This allows the second motor 4 to drive the turntable 19 to rotate. The turntable 19 is coaxially arranged with the annular plate 7.
[0040] An annular plate 7 is rotatably connected inside the outer casing 1, and several material conveying components are evenly arranged on one side of the annular plate 7. The conveying components include a first rotating plate 11 and a second rotating plate 12.
[0041] The first rotating plate 11 and the second rotating plate 12 are both rotatably connected between the turntable 19 and the annular plate 7. A torsion spring is provided between the rotating end of the first rotating plate 11 and the turntable 19 and the annular plate 7. The end face of the first rotating plate 11 away from the rotating end is inclined. In the initial state, the torsion spring drives the first rotating plate 11 to rotate, so that the inclined surface of the first rotating plate 11 abuts against the inner wall of the outer casing 1.
[0042] A support member is provided on the annular plate 7, and the support member abuts against the second inclined plate 16. One end of the second rotating plate 12 is movably mounted on the support member, and the second rotating plate 12 abuts against the first inclined plate 10.
[0043] The support includes a connecting plate 14, which is fixedly connected between the turntable 19 and the annular plate 7. The connecting plate 14 secures the turntable 19 and the annular plate 7 together. Several sliding rods 18 slide through the connecting plate 14 at intervals, and one end of each sliding rod 18 is fixedly connected to a common retaining plate 13. The retaining plate 13 has an L-shaped cross-section, and one end of the second rotating plate 12 is movably mounted on the retaining plate 13. The L-shaped design of the retaining plate 13 positions the second rotating plate 12, allowing it to rotate with the annular plate 7.
[0044] The other end of several sliding rods 18 is fixedly connected to the same sliding plate 15, and the sliding plate 15 abuts against the second inclined plate 16.
[0045] Each slide bar 18 is fitted with a spring 17 at one end near the slide plate 15. One end of the spring 17 is fixedly connected to one side of the slide plate 15, and the other end of the spring 17 is fixedly connected to one side of the connecting plate 14.
[0046] The distance between the inner wall of the outer casing 1 and the outer surface of the annular plate 7 gradually increases from top to bottom. One end of the first rotating plate 11 abuts against and slides against the inner wall of the outer casing 1. This allows the angle between the first rotating plate 11 and the second rotating plate 12 to gradually increase as the annular plate 7 drives the first rotating plate 11 to rotate downward.
[0047] The bottom of the outer casing 1 is provided with a discharge port, and a screen 8 is fixedly installed inside the discharge port. The end of the first rotating plate 11 is slidably disposed on the screen 8 so that the ground quartz sand can be discharged through the screen 8.
[0048] The outer casing 1 is equipped with a feeding and discharging assembly.
[0049] The feeding and discharging assembly includes a feed pipe 3 and a discharge pipe 9. The feed pipe 3 is fixedly inserted through the first side of the housing 1, and the end of the feed pipe 3 extends between the first inclined plate 10 and the second inclined plate 16. This facilitates the discharge of quartz sand between the two grinding rollers 5.
[0050] The discharge pipe 9 is fixedly connected to the screen 8 at the bottom of the outer casing 1. This allows the quartz sand discharged from the screen 8 to fall onto the discharge pipe 9 for easy collection.
[0051] Working principle:
[0052] In use, the two first motors 2 are started, and the output shafts of the two first motors 2 drive the corresponding grinding rollers 5 to rotate. The output shafts of the two first motors 2 rotate in opposite directions, causing the two grinding rollers 5 to rotate towards each other.
[0053] The quartz sand to be ground is put into the feed pipe 3. The quartz sand will fall onto the first inclined plate 10 and the second inclined plate 16, and then fall down along the first inclined plate 10 and the second inclined plate 16 into the space between the two grinding rollers 5.
[0054] The two grinding rollers 5 rotate to grind the quartz sand, which then falls onto the screen 8. The screen 8 filters the quartz sand, and the filtered sand falls into the discharge pipe 9. Large pieces of quartz sand remain on top of the screen 8.
[0055] The second motor 4 is started, and its output shaft drives the turntable 19 to rotate. The turntable 19 rotates outside the fixed plate 20, which in turn drives the annular plate 7 to rotate through the connecting plate 14. This causes the first rotating plate 11 and the second rotating plate 12 to rotate outside the grinding roller 5.
[0056] The connecting plate 14 drives the slide plate 15 and the clamping plate 13 to rotate, so that the end of the second rotating plate 12 moves together on the clamping plate 13.
[0057] Under the action of the torsion spring, the end of the first rotating plate 11 slides on the inner wall of the outer casing 1. As the distance between the inner wall of the outer casing 1 and the outer surface of the annular plate 7 gradually increases from top to bottom, the torsion spring drives the first rotating plate 11 to rotate, causing the angle between the first rotating plate 11 and the second rotating plate 12 to gradually increase.
[0058] The end of the first rotating plate 11 slides on the screen 8, scraping away the residual quartz sand on the screen 8. Then, the first rotating plate 11 moves upward, and under the pressure of the inner wall of the outer casing 1, it rotates towards the side closer to the second rotating plate 12. This reduces the angle between the first rotating plate 11 and the second rotating plate 12, squeezing out the scraped-away quartz sand.
[0059] When the first rotating plate 11 and the second rotating plate 12 move to the top of the outer casing 1, the quartz sand on the first rotating plate 11 will fall onto the second rotating plate 12.
[0060] When the slide plate 15 rotates to the second ramp 16, the second ramp 16 will press against the slide plate 15. At this time, the slide plate 15 is positioned on the second ramp 16, and the slide plate 15, the slide bar 18, and the locking plate 13 cannot move further. However, the connecting plate 14 continues to move, and the connecting plate 14 will slide on the slide bar 18, compressing the spring 17.
[0061] The second rotating plate 12 continues to move, and its end moves away from the clamping plate 13. At this point, under the influence of gravity, the second rotating plate 12 rotates downwards, and the quartz sand on it falls onto the second inclined plate 16. The quartz sand then continues to pass through the grinding roller 5 for grinding.
[0062] As the connecting plate 14 continues to rotate with the annular plate 7, the angle of the connecting plate 14 changes, which pulls the slide plate 15 to move via the slide rod 18, causing the slide plate 15 to move away from the second inclined plate 16. Then the spring 17 pushes the slide plate 15, causing the locking plate 13 to move until it returns to its initial state.
[0063] The second rotating plate 12 rotates to the position of the first inclined plate 10, and the first inclined plate 10 presses against the second rotating plate 12. The end of the second rotating plate 12 presses against the clamping plate 13 until the end of the second rotating plate 12 is re-clamped onto the clamping plate 13. This allows the first rotating plate 11 and the second rotating plate 12 to continue rotating with the annular plate 7, so as to continue conveying the quartz sand on the screen 8.
[0064] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
