A pressure rod 24 is slidably connected inside the slide rail 23. A return spring 26 is provided on the outer wall of the pressure rod 24. One end of the return spring 26 away from the pressure rod 24 is provided inside the slide rail 23. A rotating wheel 25 is provided at the bottom of the pressure rod 24, and the rotating wheel 25 is in rolling contact with the pushing member 19.

[0023] A boss 28 is provided at the bottom of the equipment body 1, and a rotating rod 32 is rotatably connected inside the boss 28. A belt 27 is sleeved on the rotating rod 32. The end of the belt 27 away from the rotating rod 32 is sleeved on the outer wall of the driving rod 16. A reciprocating screw 30 is provided at the end of the rotating rod 32, and a speed regulator 29 is provided between the rotating rod 32 and the reciprocating screw 30. A mounting plate is provided at the bottom of the equipment body 1, and a water tank 34 is fixedly connected to the mounting plate.

[0024] A spray barrel 35 is fixedly connected to both sides of the mounting plate, a push rod 37 is slidably connected inside the spray barrel 35, a return spring 36 is sleeved on the push rod 37, a pressure plate 33 is provided at the end of the push rod 37, and the bottom of the pressure plate 33 is threadedly sleeved on the outer wall of the reciprocating screw 30.

[0025] The interior of the spray barrel 35 is connected with a suction pipe 42 , one end of the suction pipe 42 away from the spray barrel 35 is connected to the interior of the water tank 34 , and one end of the suction pipe 42 located inside the water tank 34 is provided with an adjustment mechanism.

[0026] 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 switch valve in the feed pipe 8 can be opened. At this time, the operator can turn on the motor 6 to 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. Since the entire equipment is slightly tilted, the quartz sand entering the transmission rod 4 will slide into the screen drum 5, and the screen drum 5 will rotate and screen. When the screen drum 5 screens and refines the quartz sand, there are three situations; In the first case, when it is necessary to screen quartz sand with finer particle size, the operator only needs to start the motor 6 normally, and let the motor 6 drive the screen drum 5 to rotate at a normal speed through the transmission rod 4. When the screen drum 5 rotates normally, the quartz sand entering the screen drum 5 will be screened by the fine screen 12 in the screen opening 10, and the screened quartz sand will fall into the receiving box 38 through the discharge port on the shell 49, and will be stored in the receiving box 38. When the screen drum 5 rotates to screen the quartz sand, the driving rod 16 will also rotate synchronously. When the driving rod 16 rotates synchronously, the rotating rod 32 and the reciprocating screw 30 will be driven to rotate through the belt 27. When the reciprocating screw 30 rotates, the pressure plate 33 will push the push rod 37 to perform reciprocating suction motion inside the nozzle 35. When the push rod 37 performs reciprocating suction motion inside the nozzle 35, the suction pipe 42 will suck the water inside the water tank 34 into the nozzle 35 and then spray it out to remove dust from the quartz sand, thereby preventing the dust generated when the quartz sand is discharged from harming the environment and the health of the staff.

[0027] Example 2: Please refer to Figure 1 - Fig.18 The adjustment mechanism includes a plurality of side rails 45 arranged at the end of the suction pipe 42, and a baffle plate 46 is slidably connected inside the plurality of side rails 45. A connecting rod 47 is arranged on the outer side of the baffle plate 46. A pressure spring 48 is sleeved on one end of the connecting rod 47 located inside the side rail 45, and a clamping plate 43 is fixedly connected to the end of the connecting rod 47 away from the baffle plate 46.

[0028] Telescopic rods 39 are slidably connected to both sides of the water tank 34, and the ends of the two telescopic rods 39 are commonly connected to a connecting plate 41, and pressure rings 44 are fixedly connected to both sides of the connecting plate 41. A plurality of rollers are provided inside the pressure ring 44, and the plurality of rollers are respectively in rolling contact with the corresponding clamping plates 43, and one end of the two telescopic rods 39 away from the connecting plate 41 is commonly connected to a magnetic plate 31, and a return spring 40 is provided on the magnetic plate 31, and one end of the return spring 40 away from the magnetic plate 31 is fixedly connected to the outer wall of the water tank 34.

[0029] A circular plate 50 is provided at the end of the screen cylinder 5, and the circular plate 50 is slidably connected to the multiple slides 11. A shell 49 is provided on the equipment body 1, and a discharge port is provided on the shell 49. The end of the shell 49 is rotatably connected to the circular plate 50, and the shell 49 covers the screen cylinder 5.

[0030] In the second case of this embodiment, when it is necessary to screen quartz sand with a moderate particle size, the operator can start the motor 6 at a high power, so that it drives the screen drum 5 to rotate at a relatively fast speed through the transmission rod 4. When the screen drum 5 rotates quickly, it will drive the turntable 22 to rotate synchronously and quickly through the driving rod 16. When the turntable 22 rotates quickly, under the action of a 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. When the pressure rod 24 moves to the outside of the slide rail 23, the rotating wheel 25 at the bottom will move along the push member 1. 9 rolls along the bevel until the rotating wheel 25 moves to the middle step platform 20. When the rotating wheel 25 moves to the middle step platform 20, the pressure rod 24 presses the push plate 17, so that the push plate 17 pushes the slide plate 11 to move, so that the middle screen 13 on the slide plate 11 replaces the fine screen 12 and enters the sieve opening 10. When the middle screen 13 with a larger aperture replaces the fine screen 12 with a smaller aperture and enters the sieve opening 10, when the sieve drum 5 rotates, the quartz sand in the sieve drum 5 will be screened by the middle screen 13, so as to screen the quartz sand with a moderate particle size. Under the action of the repulsive magnetic force between the magnetic ring 18 and the magnetic plate 31, the magnetic plate 31 will be pushed to overcome the elastic force of the return spring 40 to move. 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, it will drive the two pressing rings 44 to move through the connecting plate 41. When the pressing ring 44 moves 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 until it reaches the middle part of the plywood 43. When the pressing ring 44 is located in the middle part of the plywood 43, the gathered The closing plate 43 will push the shielding plate 46 toward the center of the suction pipe 42 through the connecting rod 47 to increase the shielding area of ​​the suction pipe 42. When the end of the suction pipe 42 is blocked, the amount of water sucked by the suction pipe 42 will be reduced compared with before, and the corresponding spraying amount of the nozzle 35 will also be reduced. This is because finer-grained quartz sand is lighter and easily raises dust when discharging. Therefore, relatively more water needs to be sprayed for dust reduction. Quartz sand with moderate particle size is relatively heavy, has a stronger gathering ability, and raises relatively less dust. Therefore, only relatively less water is needed for dust removal.

[0031] 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.

[0032] The present invention also discloses a refinement process of a high-quality quartz sand refinement device, which comprises the following steps: 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; S2: When it is necessary to screen the quartz sand with finer particle size, it is only necessary to start the motor 6 normally, and let the motor 6 drive the screen drum 5 to rotate at a normal speed through the transmission rod 4. When the screen drum 5 rotates normally, the quartz sand entering the screen drum 5 will be screened by the screening mechanism; S3: When it is necessary to screen the quartz sand with moderate particle size, the motor 6 is started at high power to change the screening mechanism, and the quartz sand with moderate particle size in the screen drum 5 is screened by the screening mechanism; S4: When it is necessary to screen quartz sand with larger particle size, 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, the screening mechanism will change again to screen the large particles of quartz sand in the screen drum 5.

[0033] It should be noted that, after the sieve drum 5 has screened 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 .

[0034] It should be noted that, since a speed regulator 29 is provided between the rotating rod 32 and the reciprocating screw 30, no matter how fast the rotating rod 32 rotates, the rotation speed of the reciprocating screw 30 is constant, so the spraying frequency and strength of the nozzle 35 are also constant. When the spraying frequency and strength of the suction pipe 42 are constant, adjusting the water intake of the suction pipe 42 can play a role in adjusting the water spraying amount.

[0035] It should be noted that one-way valves are provided inside the suction pipe 42 and the spray barrel 35 to ensure that the spray barrel 35 only sprays water and the suction pipe 42 only absorbs water.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

10. A refinement process of a high-quality quartz sand refinement device, applicable to the device according to any one of claims 1 to 9, characterized in that: The process includes the following steps: S1: When in use, firstly, quartz sand is put into the grinder (3) for grinding. After the quartz sand is ground, the switch valve in the feed pipe (8) is opened, and the motor (6) is turned on so that the motor drives 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) enters the transmission rod (4) through the feed hole (9) and is rotated and screened by the screen drum (5); S2: When it is necessary to screen quartz sand with finer particle size, the motor (6) only needs to be started normally, and the motor (6) drives the screen drum (5) to rotate at a normal speed through the transmission rod (4). When the screen drum (5) rotates normally, the quartz sand entering the screen drum (5) will be screened by the screening mechanism; S3: When it is necessary to screen the quartz sand with a moderate particle size, the motor (6) is started at a high power to change the screening mechanism, and the quartz sand with a moderate particle size in the screen drum (5) is screened by the screening mechanism; S4: When it is necessary to screen the quartz sand with larger particle size, the power of the motor (6) is further increased to start the motor (6), so that the motor drives the screen drum (5) to rotate at high speed through the transmission rod (4). When the screen drum (5) rotates at high speed, the screening mechanism will change again to screen the large particles of quartz sand in the screen drum (5).
