Description

Technical Field

[0001] This utility model relates to the field of quartz sand production technology, and in particular to a grinding mechanism for the production of high-purity quartz sand. Background Technology

[0002] Quartz sand is a type of sand mainly composed of quartz particles. It has a wide range of applications in construction, glass manufacturing, and industrial fields. In order to uniformly mix different materials and improve the flowability and processing performance of the materials, it is necessary to grind the crushed quartz sand using a grinding device.

[0003] Traditional grinding mechanisms mostly employ a single rotating grinding disc or a fixed grinding disc combined with rotating pressure rollers. These structures achieve pulverization through the sliding friction of materials on the grinding disc surface. However, the unidirectional grinding force leads to uneven stress on the quartz sand particles, easily resulting in over-grinding or insufficient grinding. This makes it difficult to meet the stringent requirements of high-purity quartz sand, which requires narrow particle size distribution and minimal particle surface damage. Furthermore, the fixed grinding trajectory results in low contact efficiency between the quartz sand and the grinding disc, making it difficult to fully break down and separate impurities encased within the quartz particles, leading to poor purification results. Therefore, a grinding mechanism for the production of high-purity quartz sand is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a grinding mechanism for the production of high-purity quartz sand, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A grinding mechanism for producing high-purity quartz sand includes a housing with a door on one side. An outer grinding disc is disposed inside the housing, and a baffle is fixedly connected to the top side of the outer grinding disc. An inner grinding disc is disposed inside the outer grinding disc, and the inner grinding disc has a circular hole. A rotating column is fixedly connected inside the circular hole. The two ends of the rotating column are rotatably connected to the inner wall of the top side of the housing and the inner wall of the bottom side of the outer grinding disc, respectively. A toothed ring is fixedly sleeved on the outer side of the outer grinding disc, and a drive assembly is disposed on one side of the toothed ring. A transmission assembly is disposed between the rotating column and the drive assembly. A limit assembly is disposed inside the housing.

[0006] Preferably, the drive assembly includes a motor fixedly mounted on the top side of the housing, the output end of the motor rotatably passing through the housing and fixedly connected to a rotating rod, and the bottom end of the rotating rod being rotatably connected to the bottom inner wall of the housing.

[0007] Preferably, a gear is fixedly sleeved on the outer side of the rotating rod, and the gear meshes with the gear ring.

[0008] Preferably, the transmission assembly includes a first synchronous pulley and a second synchronous pulley fixedly sleeved on the outer side of a rotating rod and a rotating column, respectively. The first synchronous pulley and the second synchronous pulley share the same synchronous belt, and the synchronous belt meshes with the first synchronous pulley and the second synchronous pulley.

[0009] Preferably, the limiting component includes a fixing frame fixedly installed on one inner wall of the housing, the fixing frame having a circular hole, a sliding groove having a sliding groove, and multiple sliding plates being slidably installed in the sliding groove, the opposite surfaces of the multiple sliding plates being fixedly connected to the outer side of the outer grinding disc.

[0010] Preferably, the bottom side of the outer grinding disc has two through holes, and each through hole has a plug inserted into it. An electric push rod is fixedly installed on the bottom side of the outer grinding disc. The output end of the electric push rod is fixedly connected to a connecting frame. The connecting frame is U-shaped, and its two ends are fixedly connected to the bottom sides of the two plugs respectively.

[0011] Preferably, a collection box is placed on the bottom inner wall of the box, and the collection box is located below the connecting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The grinding mechanism for the production of high-purity quartz sand achieves relative rotation between the inner and outer grinding discs through the cooperation of components such as a motor, rotating rod, gear, gear ring, first synchronous wheel, second synchronous wheel and synchronous belt. This structure causes the quartz sand to be squeezed between the two grinding discs under the action of centrifugal force, and subjected to grinding forces from different directions. Compared with traditional single-direction grinding, it avoids the problem of uneven force on quartz sand particles and reduces over-grinding or insufficient grinding. At the same time, the relative rotation forms a complex grinding trajectory, ensuring full contact between the quartz sand and the grinding discs. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1-4 A grinding mechanism for producing high-purity quartz sand includes a housing 1, a door 20 on one side of the housing 1, an outer grinding disc 4 inside the housing 1, a baffle 6 fixedly connected to the top side of the outer grinding disc 4, an inner grinding disc 15 inside the outer grinding disc 4, the inner grinding disc 15 having a circular hole, a rotating column 16 fixedly connected inside the circular hole, the two ends of the rotating column 16 being rotatably connected to the inner wall of the top side of the housing 1 and the inner wall of the bottom side of the outer grinding disc 4 respectively, a toothed ring 10 fixedly sleeved on the outer side of the outer grinding disc 4, a drive assembly on one side of the toothed ring 10, a transmission assembly between the rotating column 16 and the drive assembly, a limit assembly inside the housing 1, and a drive assembly including a motor 11 fixedly mounted on the top side of the housing 1, the output end of the motor 11 rotatably passing through the housing 1 and fixedly connected to a rotating rod 12, the bottom end of the rotating rod 12... The rotating rod 12 is rotatably connected to the inner wall of the bottom side of the housing 1. A gear 13 is fixedly sleeved on the outer side of the rotating rod 12. The gear 13 meshes with the gear ring 10. A motor 11 is provided. When it is necessary to grind the quartz sand between the outer grinding disc 4 and the inner grinding disc 15, the motor 11 is started to drive the rotating rod 12 to rotate clockwise. Since the gear 13 is fixedly sleeved on the outer side of the rotating rod 12 and meshes with the gear ring 10, the gear ring 10 will drive the outer grinding disc 4 to rotate in the opposite direction under the meshing transmission of the gear 13. During the process of the outer grinding disc 4 rotating in the opposite direction, the inner grinding disc 15 and the outer grinding disc 4 can rotate relative to each other in conjunction with the transmission component. This relative rotation allows the quartz sand to be squeezed between the two grinding discs and ground under the action of centrifugal force.

[0017] Specifically, the transmission assembly includes a first synchronous pulley 14 and a second synchronous pulley 17 fixedly sleeved on the outer side of a rotating rod 12 and a rotating column 16, respectively. The first synchronous pulley 14 and the second synchronous pulley 17 share the same synchronous belt 18, which meshes with the first synchronous pulley 14 and the second synchronous pulley 17. By providing the first synchronous pulley 14 and the second synchronous pulley 17, and because the first synchronous pulley 14 and the second synchronous pulley 17 share the same synchronous belt 18, the second synchronous pulley 17 will drive the rotating column 16 connected to it to rotate synchronously clockwise under the transmission of the synchronous belt 18, thereby causing the inner grinding disc 15 fixedly sleeved on the outer side of the rotating column 16 to rotate relative to the relatively rotating outer grinding disc 4.

[0018] Specifically, the limiting component includes a fixed frame 2 fixedly installed on one inner wall of the housing 1. The fixed frame 2 has a circular hole, and a sliding groove 3 is opened in the circular hole. Multiple sliding plates 5 are slidably installed in the sliding groove 3. The opposite surfaces of the multiple sliding plates 5 are fixedly connected to the outer side of the outer grinding disc 4. By setting multiple sliding plates 5, and because the multiple sliding plates 5 are slidably installed in the sliding groove 3 opened in the fixed frame 2, it can play a limiting role when the outer grinding disc 4 rotates, ensuring the stable rotation of the outer grinding disc 4.

[0019] Specifically, the bottom side of the outer grinding disc 4 has two through holes, and each through hole has a plug 9 inserted into it. An electric push rod 7 is fixedly installed on the bottom side of the outer grinding disc 4. The output end of the electric push rod 7 is fixedly connected to a connecting frame 8, which is U-shaped. Both ends of the connecting frame 8 are fixedly connected to the bottom side of the two plugs 9 respectively. A collection box 19 is placed on the bottom inner wall of the box 1. The collection box 19 is located below the connecting frame 8. With the electric push rod 7 installed, when it is necessary to remove the formed quartz sand from the outer grinding disc 4, simply start the electric push rod 7 to drive the connecting frame 8 to move down. Then, the plugs 9, which are fixedly connected to both ends of the connecting frame 8, will move out from the two through holes of the outer grinding disc 4. After removal, the quartz sand that has been ground in the outer grinding disc 4 will fall into the collection box 19 below due to inertia. After all the quartz sand has fallen, start the electric push rod 7 again to drive the two plugs 9 to reset, and then the next batch of quartz sand can be ground.

[0020] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0021] In use: When grinding high-purity quartz sand, first open the chamber door 20 and evenly pour the quartz sand to be ground into the outer grinding disc 4. After pouring, close the chamber door 20 to ensure that the grinding process is in a closed state to prevent dust from overflowing and impurities from entering. Then, start the motor 11. The motor 11 drives the rotating rod 12 to rotate clockwise. Since the gear 13 fixedly sleeved on the outside of the rotating rod 12 meshes with the gear ring 10, under the transmission action of the gear 13, the gear ring 10 drives the outer grinding disc 4 to rotate counterclockwise. At the same time, the first synchronous pulley 14 is also fixedly sleeved on the outside of the rotating rod 12. The first synchronous pulley 14 and the second synchronous pulley 17 are connected by the same synchronous belt 18. Under the transmission of the synchronous belt 18, the second synchronous pulley 14 rotates counterclockwise. 7 drives the rotating column 16 connected to it to rotate clockwise synchronously, thereby causing the inner grinding disc 15 fixedly sleeved on the outside of the rotating column 16 to rotate relative to the outer grinding disc 4. During this process, the quartz sand is strongly squeezed between the two grinding discs under the action of centrifugal force, and is continuously subjected to grinding forces such as shearing and friction, so as to achieve efficient crushing and purification. When the grinding process is completed and the quartz sand in the outer grinding disc 4 needs to be removed, the electric push rod 7 is started. The electric push rod 7 drives the connecting frame 8 to move downward. The inserts 9 fixedly connected at both ends of the connecting frame 8 are disengaged from the two through holes opened in the outer grinding disc 4. Without the limit of the inserts 9, the ground quartz sand in the outer grinding disc 4 automatically falls into the collection box 19 below under the action of inertia, which is convenient for subsequent collection and processing.
