Description

Technical Field

[0001] This invention belongs to the field of quartz sand testing and pretreatment technology, and specifically discloses a quartz sand testing device and process with pretreatment function. Background Technology

[0002] In the field of quartz sand testing, accurate test results are crucial for its application. However, the pretreatment stage before testing has long suffered from numerous pain points. Quartz sand raw materials are prone to the adhesion of metallic impurities and contaminants such as silt. These impurities directly interfere with the accuracy of subsequent tests for chemical composition, physical properties, and other indicators, leading to distorted test data and affecting the quality judgment and grading of quartz sand. Traditional pretreatment methods mostly rely on manual operation, requiring multiple independent processes such as sieving, magnetic separation, washing, and grinding. This is not only cumbersome and time-consuming, but also prone to secondary contamination during sample transfer between processes. Furthermore, the inconsistent handling techniques among different operators make it difficult to guarantee the consistency and stability of pretreatment results. Existing testing devices generally lack integrated pretreatment functions, failing to achieve integrated operation from sample introduction to pretreatment completion, thus failing to meet the actual needs of efficient and accurate batch testing of quartz sand.

[0009] In the above technical solution, preferably, the actuating lever corresponds to the protrusion position on the fixed plate, and the throwing plate is inclined on one side of the rotating cylinder.

[0010] In the above technical solution, preferably, the guide plate is a conical guide structure, the descaling roller brush can reciprocate in the semi-circular groove, the rear side of the descaling roller brush moves through the interior of the second convex sleeve, the scraper is attached to the inner wall of the semi-circular groove, the double synchronous wheel is slidably arranged with the movable opening on the descaling roller brush, the fixed sleeve is fixedly arranged with the front end of the pretreatment box, the arc-shaped blocks of the first and second convex sleeves are staggered, the second and first convex sleeves can rotate and push, and the first motor is electrically connected to the quartz sand detection device.

[0011] In the above technical solution, preferably, the slider frame and the movable rod are slidably arranged, the fixed block and the movable rod are fixedly connected, the upper side of the movable rod is circular and inserted into the guide frame, the two sets of gears are meshed with each other, the motor is electrically connected to the quartz sand detection device, and the space between the two sections of the partition is sufficient for the filter basket and the movable rod to pass through.

[0012] A pretreatment process for quartz sand testing is also provided, for operating a quartz sand testing device with pretreatment function, comprising the following steps:

[0013] S1: The tested quartz sand is placed inside the feed box. The rotating drum adsorbs metal impurities and then scrapes them off by the scraper. Meanwhile, the quartz sand that slides down one side is repeatedly pushed by the throwing plate and sprinkled onto the surface of the rotating drum, where the falling quartz sand is adsorbed and screened again.

[0014] S2: The three sets of descaling rollers rotate counterclockwise, which drives the first cam sleeve to rotate. The arc-shaped protrusion of the second cam sleeve pushes the first cam sleeve and the descaling rollers to reciprocate laterally, thus brushing the incoming quartz sand.

[0015] S3: The forward and reverse rotation of the motor and the connected gear drives the filter basket and the internal quartz sand to shake, so that the mud and sand are filtered down. Finally, the motor drives the filter basket to pass between the two partitions and move upward to the water surface with the help of the guide frame. The air dryer then dries the quartz sand in the filter basket.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The motor drives the connected synchronous pulley 3, which in turn drives the four sets of synchronous belts to rotate, causing the fixed cylinder and the rotating cylinder to rotate counterclockwise. The quartz sand to be tested is then placed into the feed box and introduced into the pretreatment box, falling onto the surface of the rotating cylinder. Metal impurities in the quartz sand are adsorbed onto the rotating cylinder by the magnetic cylinder frame. The quartz sand slides down from the left side onto the scattering component for further processing. The adsorbed metal impurities are carried to the scraper side by the rotating cylinder, shoveled off, and then fall into the collection box for collection, thus achieving the metal impurity screening work.

[0018] 2. Quartz sand sliding down from one side falls onto the throwing plate. The motor drives the connected gears, which in turn drive another set of gears, threaded rods, and synchronous pulleys to rotate. This, in conjunction with the synchronous belt, drives the two sets of synchronous pulleys to rotate. The two sets of synchronous pulleys simultaneously drive the two sets of fixed plates and protrusions to rotate. When the rotating protrusions reach the lower position, they push the actuating rod to rotate along the rotating rod, stretching the connected spring. Under the elastic action of the spring, the throwing plate reciprocates to push the falling quartz sand, scattering it onto the surface of the rotating drum. This re-adsorbs the quartz sand that fell initially or any metal impurities that were not adsorbed in time, further improving the screening effect and beating the quartz sand covered with mud and sand.

[0019] 3. The quartz sand slides again through the guide plate into the first semi-circular groove. In conjunction with motor one and four sets of synchronous belts one, it drives three sets of double synchronous pulleys to rotate. The three sets of double synchronous pulleys drive three sets of descaling rollers to rotate counterclockwise. The rotating descaling rollers drive the convex sleeve one to rotate. The arc-shaped protrusion of the convex sleeve two pushes the convex sleeve one and the descaling rollers to move laterally back and forth, brushing the incoming quartz sand and removing the mud and sand from the surface of the quartz sand. The mud and sand are then scraped off by the scraper and sent to the next set of semi-circular grooves. The quartz sand is brushed three times, which efficiently removes the mud and sand adhering to the quartz sand. Then, it is guided to the filter basket by one side of the guide plate to complete the next step.

[0020] 4. Quartz sand falls into the filter basket. The rotation of motor two and the connected gears drives the upper meshing gears and threaded rod to perform partial forward and reverse reciprocating motion. Two sets of synchronous pulleys four and the sleeved synchronous belt two rotate, causing the two threaded sliding blocks and the filter basket to reciprocate left and right. This shakes the filter basket and the quartz sand inside, filtering out sediment while other impurities float on the surface, leaving clean quartz sand in the filter basket. Finally, motor two and the threaded rod drive the sliding blocks, fixed blocks, and filter basket to move towards the quartz sand detection device. After the filter basket passes between two partitions in the water, the movable rod is guided upwards by the guide frame. The movable rod and fixed blocks then pull the filter basket up, moving it above the water surface. A dryer then dries the quartz sand in the filter basket before it is removed for precise testing. This overall coordination improves the cleanliness of the quartz sand, achieving accurate testing. Attached Figure Description

[0032] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0034] like Figures 1 to 10 The illustrated quartz sand testing device includes a quartz sand testing device 1, a pretreatment box 2 fixedly mounted on one side of the quartz sand testing device 1, a feed box 3 fixedly mounted on the upper side of the pretreatment box 2, a magnetic separation component 4 mounted inside the pretreatment box 2, and a spraying component 5 mounted on one inner wall of the pretreatment box 2. A sludge removal component 6 is installed inside the pretreatment box 2 near the lower side of the magnetic separation component 4. A cleaning component 7 is installed inside the lower side of the pretreatment box 2. A dryer 8 is fixedly installed inside the lower side of the pretreatment box 2. A filter air vent 9 is opened on one side of the pretreatment box 2 near the dryer 8. The magnetic separation component 4 includes two sets of fixed frames 41 fixedly installed at the front and rear ends of the pretreatment box 2. A magnetic cylinder frame 42 is fixedly installed between the two sets of fixed frames 41. A rotating cylinder 43 is sleeved on the outside of the magnetic cylinder frame 42. Fixed cylinders 44 are fixedly installed on both the front and rear sides of the rotating cylinder 43. A synchronous pulley 45 is fixedly installed on the outer side of the front set of the two sets of fixed cylinders 44. A collection rack 46 is fixedly installed on one inner wall of the pretreatment box 2. A scraper 47 is fixedly installed on one side of the collection rack 46. A collection box 48 is installed below the scraper 47.

[0035] The lower side of the pretreatment box 2 is equipped with a water source that submerges a portion of the upper partition 713. A notch is provided on the lower side of the magnetic cylinder frame 42. The fixed cylinder 44 is fitted onto the rotating shaft of the magnetic cylinder frame 42 and extends to the outside of the pretreatment box 2. The upper side of the collection frame 46 has a conical guiding structure, and the lower side of the collection frame 46 has a directional structure. The scraper 47 is attached to the outer wall of the rotating cylinder 43. The collection box 48 can be pulled out from inside the pretreatment box 2.

[0036] The motor 612 drives the connected synchronous pulley 613, which in turn drives the synchronous pulley 45 to rotate in conjunction with four sets of synchronous belts 614. This causes the fixed cylinder 44 and the rotating cylinder 43 to rotate counterclockwise. The quartz sand to be tested is then placed into the feed box 3 and introduced into the pretreatment box 2, falling onto the surface of the rotating cylinder 43. Metal impurities in the quartz sand are adsorbed onto the rotating cylinder 43 by the magnetic cylinder frame 42. The quartz sand slides down from the left side onto the spraying component 5 for further processing. The adsorbed metal impurities are carried to the scraper 47 side by the rotating cylinder 43, where they are scraped off and fall into the collection box 48 for collection, thus achieving the metal impurity screening work.

[0037] The spraying assembly 5 includes two sets of drive shafts 51 rotatably mounted on the inner wall of the other side of the pretreatment box 2. Each set of drive shafts 51 has a fixed plate 52 fixedly mounted on one side inside the pretreatment box 2. Each set of fixed plates 52 has a protrusion 53 fixedly mounted on one end. Each set of drive shafts 51 has a synchronous wheel 54 fixedly mounted on the other side. A rotating rod 55 is rotatably mounted on the inner side of the pretreatment box 2 below the drive shafts 51. Two sets of actuating rods 56 are fixedly mounted on the upper side of the rotating rod 55. A spraying plate 57 is fixedly mounted on the lower side of the rotating rod 55 at an incline. Two sets of springs 58 are fixedly mounted between the spraying plate 57 and the inner wall of the pretreatment box 2.

[0038] The lever 56 corresponds to the protrusion 53 on the fixed plate 52, and the throwing plate 57 is tilted on one side of the rotating cylinder 43.

[0039] Quartz sand sliding down from one side falls onto the throwing plate 57. The motor 710 drives the connected gear 711, which in turn drives another set of gears 711, threaded rod 78, and synchronous pulley 79 to rotate. This, in conjunction with the synchronous belt 712, drives the two sets of synchronous pulleys 54 to rotate. The two sets of synchronous pulleys 54 simultaneously drive the two sets of fixed plates 52 and protrusions 53 to rotate. When the rotating protrusion 53 rotates to the lower position, it pushes the actuating rod 56 to rotate along the rotating rod 55, stretching the connected spring 58. With the elastic action of the spring 58, the throwing plate 57 reciprocates and pushes the falling quartz sand onto the surface of the rotating cylinder 43, thereby re-adsorbing the quartz sand that fell initially or the metal impurities that were not adsorbed in time, further improving the screening effect and beating the quartz sand covered with mud and sand.

[0040] The desliming assembly 6 includes a guide plate 61 fixedly installed inside the pretreatment box 2, located below the rotating cylinder 43. The guide plate 61 has three sets of semi-circular grooves 62. Desliming roller brushes 63 are rotatably mounted inside each of the three sets of semi-circular grooves 62. Scraper blades 64 are fixedly mounted inside each of the three sets of desliming roller brushes 63. Double synchronous wheels 65 are fixedly mounted on the front side of the rotating shaft of each of the three sets of desliming roller brushes 63, located outside the pretreatment box 2. Bearings 66 are fixedly sleeved on the rear side of each of the three sets of double synchronous wheels 65. Fixing sleeves 67 are fixedly mounted on the outer rings of each of the three sets of bearings 66. The front side of the rotating shaft of each of the three sets of desliming roller brushes 63 corresponds to... Each of the two synchronous pulleys 65 has an opening 68. The rear side of the rotating shaft of each of the three sets of mud removal roller brushes 63 is fixedly equipped with a convex sleeve 69. The rear end of the pretreatment box 2 is fixedly equipped with a convex sleeve 610 corresponding to the position of the convex sleeve 69. A spring 611 is fixedly installed between the convex sleeve 69 and the convex sleeve 610. A motor 612 is fixedly installed on the support at the rear side of the pretreatment box 2. A synchronous pulley 613 is fixedly installed on the outside of the rotating shaft of the motor 612. Four sets of synchronous belts 614 are fitted around the synchronous pulley 613, the three sets of double synchronous pulleys 65, and the outside of the synchronous pulley 45.

[0041] The guide plate 61 has a conical guide structure. The descaling roller brush 63 can reciprocate back and forth in the semi-circular groove 62. The rear side of the descaling roller brush 63 moves through the inside of the second convex sleeve 610. The scraper 64 is attached to the inner wall of the semi-circular groove 62. The double synchronous wheel 65 is slidably set at the position of the movable opening 68 on the descaling roller brush 63. The fixed sleeve 67 is fixedly set at the front end of the pretreatment box 2. The arc-shaped block of the first convex sleeve 69 and the second convex sleeve 610 is staggered. The second convex sleeve 610 and the first convex sleeve 69 can rotate and push. The motor 612 is electrically connected to the quartz sand detection device 1.

[0042] The quartz sand slides again through the guide plate 61 into the first semi-circular groove 62. The motor 612 and four sets of synchronous belts 614 drive three sets of double synchronous pulleys 65 to rotate. These pulleys, in turn, drive three sets of descaling rollers 63 to rotate counter-clockwise. The rotating descaling rollers 63 drive the convex sleeve 69 to rotate. The arc-shaped protrusions of the convex sleeve 610 push the convex sleeve 69 and the descaling rollers 63 to reciprocate laterally, brushing the incoming quartz sand and removing the mud and sand from its surface. The mud and sand are then scraped off by the scraper 64 into the next semi-circular groove 62. This three-stage brushing process efficiently removes the mud and sand adhering to the quartz sand. Finally, the sand is guided through one side of the guide plate 61 into the filter basket 77, completing the next step.

[0043] The cleaning assembly 7 includes two sets of sliding strips 71 fixedly mounted on the lower side of the inner walls of the front and rear sides of the pretreatment tank 2. Guide frames 72 are fixedly mounted on the upper side of each set of sliding strips 71. Sliding slider frames 73 are slidably mounted on the outer side of each set of sliding strips 71. Fixing blocks 74 are mounted on the upper side of each set of sliding slider frames 73. Movable rods 75 are mounted on the inner side of the fixing blocks 74 and the sliding slider frames 73. A spring 76 is fitted between the sliding slider frame 73 and the lower circular plate of the movable rod 75. A filter basket 77 is fixedly mounted between the two sets of fixing blocks 74. Both sets of slider frames 73 have threaded rods 78 threaded on their lower sides. Both sets of threaded rods 78 are fixedly mounted on the outer side of the pretreatment box 2 with synchronous pulleys 79. A motor 710 is fixedly mounted on a bracket on one side of the pretreatment box 2. Gears 711 are fixedly mounted on one side of the front set of the two sets of threaded rods 78 and on the rotating shaft of the motor 710. Synchronous belts 712 are fitted on the outer sides of the two sets of synchronous pulleys 79 and the two sets of synchronous pulleys 54. Two partitions 713 are fixedly mounted in the middle position inside the lower side of the pretreatment box 2.

[0044] The slider frame 73 and the movable rod 75 are slidably set, the fixed block 74 and the movable rod 75 are fixedly connected, the upper side of the movable rod 75 is circular and inserted into the guide frame 72, the two sets of gears 711 are meshed with each other, the motor 2 710 is electrically connected to the quartz sand detection device 1, and the space between the two partitions 713 is sufficient for the filter basket 77 and the movable rod 75 to pass through.

[0045] Quartz sand falls into filter basket 77. The rotation of motor 710 and connected gear 711 drives the upper meshing gear 711 and threaded rod 78 to perform partial reciprocating motion in both directions. Two sets of synchronous pulleys 79 and the sleeved synchronous belt 712 rotate, causing the two threaded sliding blocks 73 and filter basket 77 to reciprocate left and right. This shakes the filter basket 77 and the quartz sand inside, filtering out sediment while other impurities float to the surface, leaving clean quartz sand in the filter basket 77. Finally, motor 710... The threaded rod 78 drives the slider frame 73, the fixed block 74, and the filter basket 77 to move towards the quartz sand testing device 1. After the filter basket 77 passes between the two partitions 713 in the water, the movable rod 75 is guided upward by the guide frame 72. The movable rod 75 and the fixed block 74 will then pull up the filter basket 77, moving it above the water surface. The filter basket 77 is then dried in conjunction with the air dryer 8 before being taken out for precise testing. Through overall coordination, the cleanliness of the quartz sand is improved, and accurate testing is achieved.

[0046] A pretreatment process for quartz sand testing is also provided, for operating a quartz sand testing device with pretreatment function, comprising the following steps:

[0047] S1: The tested quartz sand is placed inside the feed box 3. The rotating drum 43 adsorbs metal impurities and then scrapes them off by the scraper 47. Meanwhile, the quartz sand that slides down one side is repeatedly pushed by the throwing plate 57 and sprinkled onto the surface of the rotating drum 43, where the falling quartz sand is adsorbed and screened again.

[0048] S2: The three sets of descaling rollers 63 rotate counterclockwise, which drives the convex sleeve 1 69 to rotate. The arc-shaped protrusion of the convex sleeve 2 610 pushes the convex sleeve 1 69 and the descaling rollers 63 to reciprocate laterally, thus brushing the incoming quartz sand.

[0049] S3: The motor 710 and the connected gear 711 rotate in both directions, driving the filter basket 77 and the internal quartz sand to shake, so that the mud and sand are filtered down. Finally, the motor 710 drives the filter basket 77 to pass between the two partitions 713, and with the help of the guide frame 72, it moves upward to the water surface, and with the help of the air dryer 8, the quartz sand in the filter basket 77 is dried.

[0050] Working principle: During use, motor 612 drives synchronous pulley 613 connected to it, which in turn drives synchronous pulley 45 to rotate in conjunction with four sets of synchronous belts 614. This causes the fixed cylinder 44 and the rotating cylinder 43 to rotate counterclockwise. The quartz sand to be tested is then placed into the feed box 3 and introduced into the pretreatment box 2, falling onto the surface of the rotating cylinder 43. Metal impurities in the quartz sand are adsorbed onto the rotating cylinder 43 by the magnetic cylinder frame 42. The quartz sand then slides down from the left side onto the scattering assembly 5 for further processing. The adsorbed metal impurities are then removed by the rotating cylinder. 43 is brought to the scraper 47 side, scraped off and falls into the collection box 48 for collection, realizing the screening of metal impurities; the quartz sand sliding down from one side falls onto the throwing plate 57, and the motor 710 drives the connected gear 711 to drive another set of gears 711, threaded rod 78 and synchronous pulley 79 to rotate, which in turn drives the two sets of synchronous pulleys 54 connected to the synchronous belt 712 to rotate. The two sets of synchronous pulleys 54 rotate at the same time, and the two sets of fixed plates 52 and protrusions 53 rotate. When the rotating protrusions 53 rotate to the lower position, The actuating lever 56 is pushed to rotate along the rotating rod 55, stretching the connected spring 58. Under the elastic action of the spring 58, the falling quartz sand is reciprocated by the throwing plate 57 and sprinkled onto the surface of the rotating drum 43. This re-adsorbs the initially falling quartz sand or metal impurities that have not been adsorbed in time, further improving the screening effect and beating the quartz sand covered with mud and sand. The quartz sand then slides again through the guide plate 61 into the first semi-circular groove 62, where the motor 612 and four sets of synchronous belts 614 drive the three sets of double synchronous pulleys 65 to rotate. Three sets of double synchronous wheels 65 drive three sets of descaling rollers 63 to rotate counterclockwise. The rotating descaling rollers 63 drive the first cam sleeve 69 to rotate. The arc-shaped protrusion of the second cam sleeve 610 pushes the first cam sleeve 69 and the descaling rollers 63 to reciprocate laterally, brushing the incoming quartz sand and causing the mud and sand on the surface of the quartz sand to fall off. Then, the scraper 64 scrapes it off into the next set of semi-circular grooves 62. The quartz sand is brushed three times, which efficiently removes the mud and sand adhering to the quartz sand. Then, it is guided to the filter basket 77 through one side of the guide plate 61 to complete the next step.Next, the quartz sand falls into the filter basket 77. The rotation of motor 710 and the connected gear 711 drives the upper meshing gear 711 and threaded rod 78 to perform partial reciprocating motion in both directions. The rotation of two sets of synchronous pulleys 79 and the sleeved synchronous belt 712 causes the two threaded sliding blocks 73 and the filter basket 77 to reciprocate left and right, shaking the filter basket 77 and the quartz sand inside. This causes the sediment to be filtered down, while other impurities float on the surface, leaving clean quartz sand in the filter basket 77. Finally, motor 710... The threaded rod 78 drives the slider frame 73, the fixed block 74, and the filter basket 77 to move towards the quartz sand testing device 1. After the filter basket 77 passes between two partitions 713 in the water, the movable rod 75 is guided upward by the guide frame 72. The movable rod 75 and the fixed block 74 then pull up the filter basket 77, moving it above the water surface. The air dryer 8 then dries the quartz sand in the filter basket 77 before it is removed for precise testing. Through this overall coordination, the cleanliness of the quartz sand is improved, achieving accurate testing.
