Description

Technical Field

[0001] The present invention relates to the technical field of quartz sand refinement, and specifically to a high-quality quartz sand refinement device and its refinement process. Background Technique

[0002] At present, quartz sand is an important industrial mineral raw material, widely used in industries such as glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter media, etc. However, before using quartz sand, it is necessary to filter the quartz.

[0003] After being ground by a grinding machine, quartz sand usually needs to be refined and screened. However, the aperture size of the sieve holes of the existing refinement and screening devices cannot be changed. When it is necessary to adjust the particle size of the screened quartz sand, the entire sieve mesh needs to be replaced, and multiple sieve meshes with different apertures need to be prepared, resulting in a high usage cost. At the same time, when refining and screening quartz sand, a large amount of dust is usually raised, and the existing refinement and screening devices usually lack a dust removal mechanism inside. If the dust is not suppressed, it will not only affect the environment but also the physical health of the staff. Summary of the Invention

When it is necessary to screen quartz sand with different particle sizes, the sliding plate will push medium sieve meshes, large sieve meshes, and fine sieve meshes of different sizes into the sieve openings, so as to achieve the effect of screening quartz sand with different particle sizes. The switching of the entire screening particle size is simple and fast, and there is no need to replace the filter screen again at all, greatly improving the efficiency of fine screening.

[0021] 2. Through the setting of mechanisms such as the spray nozzles, when the quartz sand after fine screening is discharged, multiple spray nozzles will spray water for dust removal at this time, and the water spray amount of the spray nozzles will be adaptively changed according to different screening particle sizes, which can ensure the dust removal effect and avoid waste caused by excessive water spraying at the same time.

[0044] A turntable 22 is fixedly sleeved on the outer side wall of the driving rod 16. Slide rails 23 are opened on both sides of the turntable 22. A pressure rod 24 is slidably connected inside the slide rails 23. A return spring 26 is arranged on the outer side wall of the pressure rod 24. One end of the return spring 26 away from the pressure rod 24 is arranged inside the slide rails 23. A runner 25 is arranged at the bottom of the pressure rod 24. The runner 25 is in rolling contact with the pushing member 19.

[0045] A convex platform 28 is arranged at the bottom of the equipment main body 1. A rotating rod 32 is rotatably connected inside the convex platform 28. A belt 27 is sleeved on the rotating rod 32. One end of the belt 27 away from the rotating rod 32 is sleeved on the outer side wall of the driving rod 16. A reciprocating lead screw 30 is arranged at the end of the rotating rod 32. A speed regulator 29 is arranged between the rotating rod 32 and the reciprocating lead screw 30.

A pressing plate 33 is arranged at the end of the push rod 37. The bottom of the pressing plate 33 is threadedly sleeved on the outer side wall of the reciprocating lead screw 30.

[0047] A suction pipe 42 is communicated and arranged inside the nozzle 35. One end of the suction pipe 42 away from the nozzle 35 is communicated to the inside of the water tank 34. An adjusting mechanism is arranged at one end of the suction pipe 42 located inside the water tank 34.

[0048] In this embodiment, when in use, first, quartz sand can be put into the grinder 3 for grinding. After the quartz sand is ground, the on-off valve inside the feed pipe 8 can be opened. At this time, the operator can turn on the motor 6, which drives the sieve cylinder 5 to rotate through the transmission rod 4. When the transmission rod 4 drives the feed hole 9 to rotate to coincide with the opening end of the feed pipe 8, the ground quartz sand conveyed by the feed pipe 8 will enter the transmission rod 4 through the feed hole 9. Since the whole equipment is slightly inclined, the quartz sand entering the transmission rod 4 will slide into the sieve cylinder 5, and the sieve cylinder 5 will perform rotational screening. When the sieve cylinder 5 screens and refines the quartz sand, there are three situations;

[0049] In the first case, when it is necessary to screen fine-grained quartz sand, the operator only needs to normally start the motor 6 at this time. The motor 6 drives the sieve drum 5 to rotate at a normal speed through the transmission rod 4. When the sieve drum 5 rotates normally, the quartz sand entering the sieve drum 5 will be screened by the fine sieve mesh 12 in the sieve opening 10. The screened quartz sand will fall into the receiving box 38 through the discharge port on the outer shell 49 and be stored by the receiving box 38. When the sieve drum 5 rotates to screen the quartz sand, the driving rod 16 will also rotate synchronously. When the driving rod 16 rotates synchronously, it will drive the rotating rod 32 and the reciprocating lead screw 30 to rotate through the belt 27. When the reciprocating lead screw 30 rotates, the pressing plate 33 will push the push rod 37 to perform a reciprocating suction movement inside the spray cylinder 35. When the push rod 37 performs a reciprocating suction movement inside the spray cylinder 35, at this time, the suction pipe 42 will suck the water inside the water tank 34 into the spray cylinder 35 and then spray it out to remove dust from the quartz sand, avoiding the dust generated when the quartz sand is discharged from harming the environment and the health of the staff.

[0050] Example 2: Please refer to Figure 1 - Figure 18 , the adjusting mechanism includes a plurality of side rails 45 arranged at the end of the suction pipe 42. A baffle plate 46 is slidably connected inside each of the plurality of side rails 45. A connecting rod 47 is arranged on the outer side of the baffle plate 46. One end of the connecting rod 47 located inside the side rail 45 is sleeved with a pressure spring 48. The end of the connecting rod 47 away from the baffle plate 46 is fixedly connected to a combined plate 43.

[0051] Both sides of the water tank 34 are slidably connected with telescopic rods 39. The ends of the two telescopic rods 39 are jointly connected with a connecting plate 41. Both sides of the connecting plate 41 are fixedly connected with pressing rings 44. A plurality of rollers are arranged inside the pressing rings 44, and the plurality of rollers are respectively in rolling contact with the corresponding combined plates 43. The ends of the two telescopic rods 39 away from the connecting plate 41 are jointly connected with a magnetic plate 31. A return spring 40 is arranged on the magnetic plate 31, and the end of the return spring 40 away from the magnetic plate 31 is fixedly connected to the outer side wall of the water tank 34.

[0052] A circular plate 50 is arranged at the end of the sieve drum 5. The circular plate 50 is slidably connected with a plurality of sliding plates 11. An outer shell 49 is arranged on the equipment main body 1. A discharge port is arranged on the outer shell 49. The end of the outer shell 49 is rotatably connected with the circular plate 50, and the outer shell 49 covers the sieve drum 5.

[0053] In this embodiment, in the second case, when moderately sized quartz sand needs to be screened, the operator can start the motor 6 at high power at this time, and let it drive the sieve cylinder 5 to rotate at a relatively fast speed through the transmission rod 4. When the sieve cylinder 5 rotates rapidly, it will drive the turntable 22 to rotate synchronously and rapidly through the driving rod 16. When the turntable 22 rotates rapidly, under the action of a large centrifugal force, the pressure rod 24 will overcome the elastic force of the return spring 26 and move towards the outside of the slide rail 23. When the pressure rod 24 moves towards the outside of the slide rail 23, the runner 25 at its bottom will roll along the hypotenuse of the pushing member 19 until the runner 25 moves to the middle step 20. When the runner 25 moves to the middle step 20, at this time, the pressure rod 24 will press the push plate 17, causing the push plate 17 to push the slide plate 11 to move, so that the middle sieve mesh 13 on the slide plate 11 replaces the fine sieve mesh 12 and enters the sieve opening 10. When the middle sieve mesh 13 with a larger aperture replaces the fine sieve mesh 12 with a smaller aperture and enters the sieve opening 10, when the sieve cylinder 5 rotates at this time, the quartz sand in the sieve cylinder 5 will be screened by the middle sieve mesh 13, so as to screen the quartz sand with a moderate particle size. While the push plate 17 is being pressed and moved, under the repulsive magnetic force between the magnetic ring 18 and the magnetic plate 31, the magnetic plate 31 will be pushed to move against the elastic force of the return spring 40. When the magnetic plate 31 is pushed by the repulsive magnetic force and the telescopic rod 39 is contracted to the maximum extent and then continues to push the telescopic rod 39, it will drive two pressure rings 44 to move through the connecting plate 41. When the pressure ring 44 moves towards the end of the suction pipe 42, the roller inside it will roll along the hypotenuse of the combined plate 43 and squeeze the combined plate 43 until it reaches the middle part of the combined plate 43. When the pressure ring 44 is located at the middle part of the combined plate 43, the converging combined plate 43 will push the shielding plate 46 to converge towards the center of the suction pipe 42 through the connecting rod 47, increasing the shielding area of the suction pipe 42. When the end of the suction pipe 42 is shielded, the suction water volume of the suction pipe 42 will be reduced compared with before, and correspondingly, the spraying volume of the spray cylinder 35 will also be reduced. Because the relatively fine quartz sand is lighter and is likely to raise dust during discharging, relatively more water needs to be sprayed for dust reduction. While the quartz sand with a moderate particle size is relatively heavier, has a stronger converging ability, and raises relatively less dust, so only relatively less water is needed for dust removal.

[0054] In the third case, when it is necessary to screen quartz sand with a larger particle size, the operator can continue to increase the power to start the motor 6, so that it drives the screen drum 5 to rotate at high speed through the transmission rod 4. When the screen drum 5 rotates at high speed, it will drive the turntable 22 to rotate synchronously at high speed through the driving rod 16. When the turntable 22 rotates at high speed, under the action of large centrifugal force, the pressure rod 24 will overcome the elastic force of the return spring 26 and move to the outside of the slide rail 23. At this time, the rotating wheel 25 at the bottom will roll along the bevel of the pusher 19 until the rotating wheel 25 moves to the high ladder. When the rotating wheel 25 moves to the high ladder platform 21, the pressure rod 24 presses the push plate 17, so that the push plate 17 pushes the slide plate 11 to move a large distance, so that the large screen 14 on the slide plate 11 enters the screen opening 10. When the large screen 14 with the largest aperture enters the screen opening 10, when the screen drum 5 rotates, the quartz sand in the screen drum 5 will be screened by the large screen 14, so as to screen the quartz sand with a larger particle size. When the push plate 17 is pressed to move a large distance, under the action of the repelling magnetic force, it will also push the magnetic plate 31 to overcome the return The elastic force of the spring 40 is used for long-distance movement. When the magnetic plate 31 pushes the telescopic rod 39 to shrink to the maximum extent under the action of the repulsive magnetic force, and then continues to push the telescopic rod 39 for long-distance movement, the two pressing rings 44 will be driven to move long-distance through the connecting plate 41. When the pressing ring 44 moves a long distance toward the end of the suction tube 42, the roller inside it will roll along the oblique edge of the plywood 43 to squeeze the plywood 43 for a long distance, so that the plywood 43 is gathered to the maximum extent until it reaches the top of the plywood 43. When the pressing ring 44 is at the top of the plywood 43, The maximally gathered plywood 43 will push the shielding plate 46 to move a greater distance toward the center of the suction pipe 42 through the connecting rod 47, and continue to increase the shielding area of ​​the suction pipe 42. When the end of the suction pipe 42 is shielded by a large area, the amount of water sucked by the suction pipe 42 will be reduced compared with the second case, and the corresponding spraying amount of the nozzle 35 will also be reduced. This is because larger particles of quartz sand are heavier and the dust raised is smaller than that of medium-sized quartz sand particles. Therefore, only less water is needed for dust removal, which ensures the dust removal effect while avoiding waste caused by excessive water spraying.

[0055] The present invention also discloses a refinement process of a high-quality quartz sand refinement device, which comprises the following steps:

[0056] S1: When in use, first put the quartz sand into the grinder 3 for grinding. After the quartz sand is ground, open the switch valve in the feed pipe 8, turn on the motor 6, and drive the screen drum 5 to rotate through the transmission rod 4. When the transmission rod 4 drives the feed hole 9 to rotate to coincide with the open end of the feed pipe 8, the ground quartz sand transported by the feed pipe 8 will enter the transmission rod 4 through the feed hole 9 and be rotated and screened by the screen drum 5;

[0057] S2: When it is necessary to screen quartz sand with a finer particle size, only start the motor 6 normally at this time. Let the motor 6 drive the sieve drum 5 to rotate at a normal speed through the transmission rod 4. When the sieve drum 5 rotates normally, the quartz sand entering the sieve drum 5 will be screened by the screening mechanism;

[0058] S3: When it is necessary to screen quartz sand with a moderate particle size, start the motor 6 with high power, change the screening mechanism, and screen the quartz sand with a moderate particle size in the sieve drum 5 through the screening mechanism;

[0059] S4: When it is necessary to screen quartz sand with a larger particle size, continue to increase the power to start the motor 6, let it drive the sieve drum 5 to rotate at a high speed through the transmission rod 4. When the sieve drum 5 rotates at a high speed, at this time the screening mechanism will change again to screen the large-particle quartz sand in the sieve drum 5.

[0060] It should be noted that after the sieve drum 5 screens the quartz sand, the quartz sand remaining in the sieve drum 5 can be discharged through the discharge port at the bottom of the sieve drum 5.

[0061] It should be noted that since a speed regulator 29 is provided between the rotating rod 32 and the reciprocating lead screw 30, no matter at what speed the rotating rod 32 rotates, the rotating speed of the reciprocating lead screw 30 is constant. Therefore, the spraying frequency and intensity of the spray tube 35 are also constant. When the spraying frequency and intensity of the suction pipe 42 are constant, adjusting the water intake of the suction pipe 42 can play a role in adjusting the water spray volume.

[0062] It should be noted that one-way valves are provided inside both the suction pipe 42 and the spray tube 35, which can ensure that the spray tube 35 only sprays water and the suction pipe 42 only sucks water.

[0063] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0064] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
