DETAILED DESCRIPTION

[0020] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] A roughing device for producing high-purity quartz sand according to a preferred embodiment of the present invention will be described in detail below.

[0022] Embodiment 1, as Figure 1-Figure 10 As shown, it comprises a roughing cylinder 1, and a crushing mechanism 2 and a drying mechanism 3 are arranged inside the roughing cylinder 1; The pulverizing mechanism 2 includes a first pulverizing cylinder 201 and a second pulverizing cylinder 202 disposed inside the roughing cylinder 1. The first pulverizing cylinder 201 is located inside the second pulverizing cylinder 202. A plurality of separation holes 203 are provided on the surfaces of the first pulverizing cylinder 201 and the second pulverizing cylinder 202. The drying mechanism 3 includes a drying plate 301 arranged inside the first crushing cylinder 201, the drying plate 301 is set as a hollow structure, an extension rod 302 is fixedly installed on the inner bottom of the drying plate 301, a linkage plate 303 is slidably installed inside the drying plate 301, the extension rod 302 penetrates and extends to the top of the linkage plate 303, a vent 304 is opened on the surface of the extension rod 302, the linkage plate 303 is set as a hollow structure, a plurality of first crushing blocks 204 are arranged on the surface of the first crushing cylinder 201, a plurality of second crushing blocks 205 are arranged on the inner wall of the second crushing cylinder 202, the first crushing blocks 204 and the second crushing blocks 205 are set as wedge-shaped blocks, and a drying fan 305 is arranged below the drying plate 301; When in use, the staff first starts the first crushing cylinder 201 to rotate, and the first crushing cylinder 201 drives the second crushing cylinder 202 to rotate synchronously, and then places the quartz sand that needs to be roughly selected inside the first crushing cylinder 201. At this time, due to the rotation of the first crushing cylinder 201, the quartz sand will rotate inside the first crushing cylinder 201 under the action of centrifugal force. At this time, the quartz sand will hit the inside of the first crushing cylinder 201, thereby playing a crushing role, crushing some large impurities or large pieces of quartz sand. When the size of the crushed quartz sand is smaller than the separation hole 203 opened on the surface of the first crushing cylinder 201, it will be thrown out to the inside of the second crushing cylinder 202, so as to be crushed twice, until the size of the crushed quartz sand is roughly composite, it will be thrown out from the second crushing cylinder 202 to the rough selection cylinder 1, and then fall down to discharge. If there is too much quartz sand inside the first crushing cylinder 201 or the water content is high, it will cause the quartz sand to accumulate inside the first crushing cylinder 201, resulting in poor crushing effect. At this time, the quartz sand will be driven by the weight to dry. The linkage plate 303 inside the dry plate 301 moves downward. Due to the downward movement of the linkage plate 303, the extension rod 302 will extend. At this time, the staff controls the first crushing cylinder 201 to reverse. At this time, the second crushing cylinder 202 will drive the drying plate 301 to rotate inside the first crushing cylinder 201. At this time, the extension rod 302 extending from the drying plate 301 will stir the quartz sand accumulated in the first crushing cylinder 201 to prevent it from accumulating. At the same time, the drying fan 305 will deliver wind to the first crushing cylinder 201. The quartz sand is blown dry. At the same time, when the first crushing cylinder 201 drives the second crushing cylinder 202 to reverse, the contact area between the quartz sand and the first crushing block 204 and the second crushing block 205 is large, so that the quartz sand with a large water content can be quickly crushed to prevent it from accumulating inside the second crushing cylinder 202. At the same time, when the first crushing cylinder 201 and the second crushing cylinder 202 are reversed, the quartz sand attached to the inner wall can be thrown off due to centrifugal force. The crushing mechanism 2 provided can increase the impact and friction between particles, so that the quartz sand and other impurities are crushed more effectively. The two groups can maximize the crushing effect, thereby accelerating the processing speed and improving production efficiency. At the same time, if the quartz sand and other impurities have a high water content, the accumulation and blockage of materials during the crushing process can be avoided by adjusting the first crushing cylinder 201 and the second crushing cylinder 202 to reverse. At the same time, the extension rod 302 can be used to stir the materials accumulated inside the first crushing cylinder 201 to avoid adhesion and ensure the fluidity of the materials. At the same time, during the reversal, the first crushing block 204 and the second crushing block 205 have a larger contact area with the quartz sand and other impurities, which can provide a stronger friction effect, further improve the crushing effect, and can quickly crush the quartz sand and other impurities with a large water content, thereby roughly selecting the quartz sand and materials.

When the connecting gear 7 rotates, it meshes with the matching gear 8 and drives it to rotate synchronously. When the matching gear 8 rotates, it drives the connecting cylinder 5 to rotate synchronously. When the connecting cylinder 5 rotates, it can drive the first crushing cylinder 201 and the second crushing cylinder 202 to rotate, thereby crushing the quartz sand and other impurities; The servo motor 9 is arranged to drive the first crushing drum 201 and the second crushing drum 202 to rotate synchronously, so that the quartz sand and other impurities produce a strong rotation effect through centrifugal force, which increases the impact and friction between the materials, thereby accelerating the crushing process of the quartz sand and other impurities and improving the overall crushing efficiency.

[0025] Embodiment 4, as Figure 1-Figure 10 As shown, the surface of the first crushing cylinder 201 is provided with a first adjustment mechanism 10, the first adjustment mechanism 10 includes a sealing plate 101 slidably mounted on the surface of the first crushing cylinder 201, and the sealing plates 101 are provided with a plurality of groups, and a connecting rod 102 is fixedly installed between the sealing plates 101, and the connecting rod 102 can penetrate into the inside of the sealing plate 101, and a return spring 103 is sleeved on the surface of the connecting rod 102, and the sealing plate 101 is used to block the separation hole 203, and the surfaces of the first crushing cylinder 201 and the second crushing cylinder 202 are both fixedly installed with an electric telescopic rod 104, and the output end of the electric telescopic rod 104 is fixedly connected to the uppermost sealing plate 101, and the surface of the second crushing cylinder 202 is provided with a second adjustment mechanism 11, and the second adjustment mechanism 11 has the same structure as the first adjustment mechanism 10; When the electric telescopic rod 104 is started, the electric telescopic rod 104 can drive the sealing plate 101 to move downward. During the downward movement of the sealing plate 101, the sealing plate 101 can squeeze the return spring 103 while moving, thereby blocking the separation hole 203; The size of the separation hole 203 can be adjusted by using the first adjustment mechanism 10 and the second adjustment mechanism 11, so as to adapt the size requirements of the rough quartz sand and other impurities according to the needs.
