DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 to 4, the present invention provides a technical solution: a cleaning device for quartz sand processing with a sorting function, including two first annular support seats 1. A second annular support seat 2 is provided inside each of the first annular support seats 1. One end of the second annular support seat 2 is located inside the first annular support seat 1 and the two are connected by a support bearing 25, enabling the second annular support seat 2 to rotate freely inside the first annular support seat 1; As Figure 1 shown, the other end of the second annular support seat 2 extends outside the first annular support seat 1, and a screening device is provided between the two second annular support seats 2; As Figure 1 and Figure 3 shown, the present invention further includes a support main shaft 9 passing through the screening device, the first annular support seat 1, and the second annular support seat 2. A second mounting disk 12 is coaxially installed on the support main shaft 9 located inside the first annular support seat 1. The second mounting disk 12 and the first annular support seat 1 are connected by a plurality of radially arranged second support rods 13; A driving device is installed at one end of the support main shaft 9. The driving device is used to drive the support main shaft 9 to drive the second annular support seat 2 and the screening device to rotate. And the mutually remote ends of the first annular support seats 1 are sealed by a sealing plate 35. The support main shaft 9 penetrates the sealing plate 35 and the two are rotatably connected. The quartz sand to be screened is loaded in the screening device and then rotates with the screening device, and the particles that meet the requirements can be left in the screening device.

[0020] As Figure 2 shown, the driving device includes a speed reducer 21 installed at the end of the support main shaft 9. The other end of the speed reducer 21 is connected to a driving motor 22, and the driving motor 22 increases the torque through the speed reducer.

[0021] As Figure 1 shown, the screening device includes a first annular fixing ring 4 coaxially arranged between the two second annular support seats 2. A first mounting disk 23 is coaxially installed on the support main shaft 9 located inside the first annular fixing ring 4. The first mounting disk 23 and the first annular fixing ring 4 are connected by a plurality of radially arranged first support rods 5; Both sides of the first annular fixing ring 4 are connected with a plurality of equally spaced third support rods 17. The other ends of the third support rods 17 are all connected to the side surface of the second annular support seat 2 far from the first annular support seat 1; Among them, as Figure 1 and Figure 2 shown, the diameter of the first annular fixing ring 4 is smaller than the diameter of the second annular support seat 2, so that the space shape surrounded by the first annular fixing ring 4 and the third support rods 17 on both sides of it is an hourglass-shaped structure with a narrow middle and wide ends at both ends; Outside the hourglass-shaped structure, a layer of screen (not shown in the figure) is provided. The screen is hermetically connected between the first annular fixing ring 4, the third support rod 17 and the second annular support seat 2. As Figure 3 shown, the volume of quartz sand filled into the screen does not exceed two-thirds of the internal volume of the screen. During the rotation process, the quartz sand rotates inside the screen, and the quartz sand rubs against each other. Moreover, particles with diameters not meeting the requirements can flow out of the screen, or the quartz sand flowing out into the cleaning pool 20 is collected.

[0022] As Figure 1 shown, between the third support rods 17, multiple second annular fixing rings 6 arranged at intervals are provided. The second annular fixing rings 6 are hermetically connected to the screen, and the second annular fixing rings 6 play a role in reinforcement.

[0023] As Figure 3 shown, the inner surface of the first annular support seat 1 is an inclined surface 24 inclined towards the screening device side. The bottom of the inclined surface 24 is flush with the end of the second annular support seat 2. On the side of the second support rod 13 away from the screening device, stirring blades 7 are connected. The stirring blades 7 are in a spiral structure, and the bottom of the stirring blades 7 is tangent to the inclined surface 24. During the rotation process, the stirring blades 7 drive the quartz sand to move towards the inside of the screen, avoiding a large amount of quartz sand accumulating in the first annular support seat 1.

[0024] As Figure 1 shown, on the top of at least one of the first annular support seats 1, a feeding channel 8 is installed. The top of the feeding channel 8 is connected to a screw feeding structure; at the bottom of the first annular support seat 1 corresponding to the feeding channel 8, a discharging valve 11 is installed, and at the bottom of the discharging valve 11, a screw discharging structure is installed; The bottoms of the first annular support seats 1 are all installed on the support frame 10, and the support frame 10 is installed in the cleaning pool 20. The part of the screening device submerged in the water in the cleaning pool 20 does not exceed half of its own, that is, the cleaning water reaches the support main shaft 9; As Figure 2 shown, at least one water inlet 27 and an overflow port 28 are provided at the top of the cleaning pool 20. At least one sewage valve 29 is installed at the bottom of the cleaning pool 20. The water inlet 27 is connected to a water supply pump through a pipeline, and the water flushing into the cleaning pool 20 flows out from the overflow port 28.

[0025] As Figure 4 shown, the screw feeding structure includes a feeding cylinder 14, and the screw discharging structure includes an output cylinder 3. A first feeding pipe 16 is installed at the bottom of the output cylinder 3, and a second feeding pipe 26 is installed at the bottom of the feeding cylinder 14. The first feeding pipe 16 and the second feeding pipe 26 are vertically upward, and a feeding hopper 15 is installed at the top of the second feeding pipe 26. A vibration motor 30 is installed outside the feeding hopper 15; Among them, a second discharge pipe 33 is installed at the top of the feed cylinder 14, a first discharge pipe 18 is installed at the top of the output cylinder 3, the first feed pipe 16 is installed below the discharge valve 11 through a flange, and the second discharge pipe 33 is installed at the top of the feed channel 8 through a flange; Both ends of the feed cylinder 14 and the output cylinder 3 are connected with sealing end covers 34 through flanges. A spiral conveyor shaft 31 is arranged in both the feed cylinder 14 and the output cylinder 3. Both ends of the spiral conveyor shaft 31 are rotatably connected to the sealing end covers 34. A conveying motor 19 connected to the spiral conveyor shaft 31 is installed at the top of both the feed cylinder 14 and the output cylinder 3.

[0026] As Figure 4 shown, at least one fixing bracket 32 is installed on both the feed cylinder 14 and the output cylinder 3 to support the feed cylinder 14 and the output cylinder 3. In the actual application process, the quartz sand to be cleaned is placed in each feed hopper 15. The quartz sand in the feed hopper 15 is sent into the screen through the spiral conveyor shaft 31. Then, the driving motor 22 is controlled to drive the screen to rotate, so that the quartz sand in the screen is quickly screened and cleaned. Since the shape of the screen is hourglass-shaped, during the rotation process, the sand will flow along both ends of the screen, which not only facilitates the output of the material through the output cylinder 3, but also facilitates the rolling of the material.
