[0002] Quartz sand is a quartz particle obtained by crushing and processing quartzite, and in the production process of quartz sand, the quartz sand needs to be scrubbed to remove the dirt such as mud and impurities adhered to the surface of the material and improve the purity of the quartz sand.

[0003] In the prior art, in the process of scrubbing the quartz sand, a stirring shaft is usually directly used to drive stirring blades to stir the sand slurry, so that the sand slurry rotates and flows, and the quartz sand in the sand slurry flows and collides with each other to remove the dirt on the surface of the quartz sand, and in the process of stirring and scrubbing the quartz sand by the current quartz sand scrubbing device, the mud and sand falling from the surface of the quartz sand still remains in the quartz sand slurry, and there is a relatively large probability that the mud and sand will be re-adsorbed on the surface of the quartz sand, resulting in poor scrubbing effect.

[0004] In addition, the quartz sand particles produced after the quartzite is fractured are of different sizes, and if the quartz sand is directly scrubbed, the large quartz sand particles will collide with the small quartz sand particles, and the small quartz sand particles can be crushed again, resulting in an increase in the amount of fine powder and affecting the particle size uniformity and the compressive strength of the fracturing sand.

[0005] Therefore, it is necessary to design a device for realizing scrubbing treatment process of quartz sand, which can classify the quartz sand particles according to the size and directly discharge the dirt such as mud and sand outward in the scrubbing process, so as to solve the problems that the mud and sand can be re-adsorbed on the surface of the quartz sand in the process of scrubbing the quartz sand by the existing device and the collision of the quartz sand particles in the scrubbing process leads to an increase in the amount of fine powder and affects the particle size uniformity and the compressive strength of the quartz sand.

[0039] Example 2: based on example 1, asFigures 2-4 and Figures 6-7 As shown, the lifting and discharging mechanism includes bevel teeth 2021, a sliding frame 3, a bevel gear 301, a swing push rod 302, a connecting frame 303, a return spring 304 and a material dividing assembly. The bevel teeth 2021 are fixedly connected to the rotating ring 202, and the bevel gear 301 is rotatably connected in the separation cylinder 1. The bevel gear 301 meshes with the bevel teeth 2021. The swing push rod 302 is fixedly connected to the rotating shaft of the bevel gear 301, and the swing push rod 302 rotates with the bevel gear 301. The sliding frame 3 is slidably connected in the separation cylinder 1, and the connecting frame 303 is fixed on the sliding frame 3. The connecting frame 303 is located above the swing push rod 302. The sliding frame 3 and the separation cylinder 1 are connected by a return spring 304.

The material dividing assembly is installed on the screening frame 2, and the material dividing assembly is used to classify and recycle quartz sand according to particle size.

[0040] like Figure 3 、 Figure 6 and Figure 7 As shown, the material dividing assembly includes fine sieve holes 207, a lifting partition 4, a round rod 4001, a first magnet 401, a second magnet 402 and a coarse material discharge frame 305. Fine sieve holes 207 are evenly spaced on the side wall of the screening frame 2. Small particles of quartz sand can be discharged outward into the separation cylinder 1 through the fine sieve holes 207. A lifting partition 4 is slidably connected to the sliding frame 3. A round rod 4001 is fixed to the top of the lifting partition 4. The round rod 4001 is located outside the screening frame 2. The first magnet 401 is fixed to the lifting partition 4. The coarse material discharge frame 305 is fixed to the separation cylinder 1. Large particles of quartz sand are discharged outward from the coarse material discharge frame 305. The second magnet 402 is fixed to the coarse material discharge frame 305. The first magnet 401 and the second magnet 402 attract each other.

[0041] The rotating ring 202 rotates to drive the bevel gear 2021 to rotate, and the rotating ring 202 rotates one circle to drive the bevel gear 301 to rotate by a certain angle, and with the continuous rotation of the bevel gear 301, the swing push rod 302 rotates, when the swing push rod 302 contacts with the connecting frame 303, the quartz sand has completed the preliminary scrubbing, with the continuous rotation of the bevel gear 301, the swing push rod 302 will push the sliding frame 3 to slide upward and compress the return spring 304 through the connecting frame 303, when the sliding frame 3 starts to rise, the fine sieve hole 207 of the side wall of the screening frame 2 leaks, so that the small particle quartz sand in the screening frame 2 is discharged from the fine sieve hole 207 into the separation cylinder 1, and the large particle quartz sand cannot flow outward from the fine sieve hole 207, with the continuous rising of the sliding frame 3, when the sliding frame 3 contacts with the top end of the top rod 4001 of the lifting partition plate 4, under the driving of the sliding frame 3, the first magnet 401 overcomes the magnetic force of the second magnet 402, so that the lifting partition plate 4 and the first magnet 401 move upward with the sliding frame 3, thereby opening the larger outlet on the side of the screening frame 2 corresponding to the lifting partition plate 4, so that the residual large particle quartz sand in the screening frame 2 is discharged from the coarse discharge frame 305, with the continuous rotation of the rotating ring 202, the bevel gear 2021 continues to drive the swing push rod 302 to rotate through the bevel gear 301, the swing push rod 302 swings upward to the highest position and then continues to rotate with the bevel gear 301, in this process, the return spring 304 continuously pushes the sliding frame 3 and the connecting frame 303 to slide downward, when the swing push rod 302 is out of contact with the connecting frame 303, the sliding frame 3 and the connecting frame 303 slide downward to reset, the lifting partition plate 4 resets downward, and the fine sieve hole 207 on the screening frame 2 and the larger outlet inside are blocked, at this time, a new batch of quartz sand slurry can be poured into the screening frame 2 for scrubbing.

[0042] As shown in Figure 3 and Figure 5 , further comprising a shaking assembly for sliding the rotating screen 204 up and down, the shaking assembly comprises a fixed lug 2031, a supporting spring 2032 and a rotating lug 205, the rotating lug 205 is fixed on the top of the rotating screen 204 and rotates with the rotating screen 204, the fixed lug 2031 is fixed on the bottom of the fixed frame 203, the rotating lug 205 contacts with the fixed lug 2031 in the process of rotation, and the rotating screen 204 is connected with the rotating ring 202 through the supporting spring 2032, one end of the supporting spring 2032 is fixed on the rotating screen 204, and the other end is fixed on the rotating ring 202.

[0043] The rotating shaft 201 drives the rotating screen 204 and the rotating block 205 to rotate. When the rotating block 205 contacts the fixed block 2031, the fixed block 2031 pushes the rotating block 205 and the rotating screen 204 to slide downward along the rotating ring 202 and compress the supporting spring 2032 as the rotating screen 204 continues to rotate. When the rotating block 205 is disengaged from the fixed block 2031, the rotating screen 204 slides upward to reset under the push of the supporting spring 2032, so that the rotating screen 204 slides up and down during rotation to reduce the probability of the screen holes of the rotating screen 204 being blocked.

[0044] Example 3: Based on example 2, as shown in Figure 1 、 Figure 8 、 Figure 9 and Figure 13 , further comprising a secondary scrubbing mechanism for re-scrubbing small particle quartz sand, the secondary scrubbing mechanism comprising a belt drive 103, an agitation cylinder 104, a conveying frame 105, a screen cylinder 5, a rotating frame 501, a discharge frame 505, and a moving extrusion assembly. The separation cylinder 1 is provided with the agitation cylinder 104 on the right side, and the conveying frame 105 is fixedly connected to the separation cylinder 1. The inlet of the conveying frame 105 is located at the lowest part of the inclined bottom plate 1001, and the other end of the conveying frame 105 passes through the agitation cylinder 104 and is fixedly connected thereto. The agitation cylinder 104 is fixedly connected with the screen cylinder 5, and the output port of the conveying frame 105 communicates with the screen cylinder 5. The rotating frame 501 is rotatably connected to the agitation cylinder 104, and the rotating shaft 201 is connected to the rotating frame 501 through the belt drive 103. The screen cylinder 5 is provided with the discharge frame 505 on the other side, and the discharge frame 505 passes through the agitation cylinder 104 and extends outward. The height of the outlet of the conveying frame 105 is higher than that of the discharge frame 505. The moving extrusion assembly is installed in the screen cylinder 5, and is used for extruding the slurry in the screen cylinder 5 and discharging the mud water therein outward.

[0045] As shown in Figure 9 and Figure 13 , the moving extrusion assembly comprises a sealing rotating plate 502, a bidirectional reciprocating wire rod 503, and a lifting agitation frame 504. The rotating frame 501 is symmetrically and slidably connected with two sealing rotating plates 502. The screen cylinder 5 is fixedly connected with the bidirectional reciprocating wire rod 503, and the screw directions of the two ends of the bidirectional reciprocating wire rod 503 are opposite. The lifting agitation frame 504 is fixedly connected to the two sealing rotating plates 502, and is threadedly connected with the bidirectional reciprocating wire rod 503. The sealing rotating plate 502 and the lifting agitation frame rotate with the rotating frame 501. The lifting agitation frame 504 slides along the bidirectional reciprocating wire rod 503 during rotation, thereby driving the two sealing rotating plates 502 to move closer to or farther away from each other.

[0046] As shown in Figure 9The sealing rotating plate 502 is provided with a sliding baffle 5021, and the sliding baffle 5021 is slidably connected in the stirring cylinder 104. An annular sliding groove is formed in the top of the sealing rotating plate 502, and the bottom of the sliding baffle 5021 is rotatably connected in the annular sliding groove in the top of the sealing rotating plate 502, so that the sliding baffle 5021 can slide up and down with the sealing rotating plate 502.

[0047] When the device is used for secondary scrubbing of quartz sand, water washing is adopted, clean water is added through the through hole at the top of the outer wall of the screen cylinder 5, and the slurry formed by the stirring of the clean water and the quartz sand will make the slurry shake. With the continuous addition of clean water into the screen cylinder 5, the quartz sand slurry will overflow the discharge frame 505, and the top part of the quartz sand slurry will flow out through the discharge frame 505. The small particle quartz sand discharged from the fine screen hole 207 of the screening frame 2 will fall on the inclined bottom plate 1001, and the small particle quartz sand will roll along the inclined bottom plate 1001 and slide into the conveying frame 105. Then it enters the screen cylinder 5 through the outlet of the conveying frame 105. A circular through hole is formed at the upper position of the outer wall of the screen cylinder 5. Clean water is continuously added through the through hole at the top of the outer wall of the screen cylinder 5 during the scrubbing process of the quartz sand. The clean water is mixed with the quartz sand slurry entering the screen cylinder 5. When the driving motor 101 drives the rotating shaft 201 to rotate, it will drive the rotating frame 501 to rotate through the belt transmission member 103. The rotating frame 501 rotates and drives the sealing rotating plate 502 and the lifting stirring frame 504 to rotate. The lifting stirring frame 504 rotates and stirs the quartz sand slurry to scrub the quartz sand. During the process of the lifting stirring frame 504 rotating and stirring the quartz sand slurry, most of the impurities washed off from the surface of the quartz sand will flow out from the through hole of the outer wall of the screen cylinder 5 with the water flow. The two lifting stirring frames 504 rotate and move towards each other or away from each other along the bidirectional reciprocating wire rod 503. When the two lifting stirring frames 504 move towards each other, the two sealing rotating plates 502 move and push the quartz sand slurry in the screen cylinder 5, increasing the pressure of the quartz sand slurry in the screen cylinder 5. The mud and sand in the quartz sand slurry are discharged from the through hole of the outer wall of the screen cylinder 5, and at the same time, the through hole of the outer wall of the screen cylinder 5 is unblocked. When the two lifting stirring frames 504 move away from each other, the two sealing rotating plates 502 move and reset. During the upward movement of the sealing rotating plate 502, clean water is continuously added through the through hole at the top of the outer wall of the screen cylinder 5. When the sealing rotating plate 502 rises to a height higher than the discharge frame 505, the liquid containing quartz sand in the screen cylinder 5 rises to the discharge frame 505. With the continuous addition of clean water into the screen cylinder 5, the liquid containing quartz sand at the top will be discharged from the discharge frame 505. When the upper sealing rotating plate 502 moves downward, it will drive the sliding baffle 5021 to slide downward. When the sealing rotating plate 502 descends to the position below the outlet of the conveying frame 105, the sliding baffle 5021 just blocks the outlet of the conveying frame 105, preventing the quartz sand slurry from continuously entering the screen cylinder 5 from the conveying frame 105. When the sealing rotating plate 502 rises and resets, the sliding baffle 5021 opens the outlet of the conveying frame 105, and the quartz sand slurry can enter the screen cylinder 5 again. The impurities passing through the through hole of the screen cylinder 5 and entering the stirring cylinder 104 will flow downward and finally be discharged from the outlet at the bottom of the stirring cylinder 104.

[0048] As Figure 10 and Figure 11The illustrated, also includes the secondary scrubbing of quartz sand slurry screening swing screening mechanism, swing screening mechanism block fixed plate 6, swing motor 601, push rotary table 602, swing sieve plate 603 and torsional spring 604, agitating cylinder 104 outside symmetry has two fixed plate 6, two fixed plate 6 inside rotary connection has swing sieve plate 603, from the discharge frame 505 outwardly discharged quartz sand slurry will fall on the swing sieve plate 603, swing sieve plate 603 and fixed plate 6 between through torsional spring 604 interface, agitating cylinder 104 outside installation has swing motor 601, agitating cylinder 104 outside rotary connection has push rotary table 602, swing motor 601 output shaft and push rotary table 602 interface, push rotary table 602 outside fixedly connected with hemispherical protrusion, push rotary table 602 in the process of rotation, push rotary table 602 outside hemispherical protrusion and torsional spring 604 cooperate, so that swing sieve plate 603 can swing up and down and discharge frame 505 discharged quartz sand slurry is screened.

[0049] The quartz sand slurry discharged from the screen cylinder 5 falls into the swing sieve plate 603 from the discharge frame 505, and the surface of the quartz sand particles on the swing sieve plate 603 may have some impurities adsorbed on them. At this time, the quartz sand particles on the swing sieve plate 603 are washed by an external water flow. The swing motor 601 is started, and the swing motor 601 drives the push rotary table 602 to rotate. In the process of rotation of the push rotary table 602, the hemispherical protrusion on the outside of the push rotary table 602 will contact the swing sieve plate 603 and press the distal end of the swing sieve plate 603 upward. When the push rotary table 602 and the swing sieve plate 603 are disengaged, the swing sieve plate 603 is swung downward under the action of the torsional spring 604. The swing sieve plate 603 is constantly shaken up and down to make the quartz sand particles shake up and down, so that the quartz sand particles are washed clean by the water flow.
