Technical Field

[0001] The present invention relates to the technical field of preparing high-purity fused silica powder, and particularly relates to an apparatus and method for recycling waste quartz crucibles to prepare high-purity fused silica powder. Background Art

[0002] The equipment for preparing high-purity fused silica powder is a device for pulverizing waste quartz glass tubes. When preparing high-purity fused silica powder, the raw material, waste quartz crucibles, are cleaned and dried to remove dust and impurities on the surface. Then, the raw material and grinding balls are placed inside a storage cylinder, and the storage cylinder is rotated by a first motor, so that the raw material can be well pulverized. After pulverization, the raw material is sieved to obtain fused quartz sand with a particle size of 40 - 200 mesh. Then, through pickling and magnetic separation, high-purity fused quartz sand is obtained. Then, it is pulverized by a jet mill to obtain high-purity fused silica powder with a D50 of 1 - 50 μm.

[0003] The inventor found in daily work that there are at least the following problems in the preparation of high-purity fused silica powder: When preparing high-purity fused silica powder, the raw material, waste quartz crucibles, are cleaned and dried to remove dust and impurities on the surface. Then, the raw material and grinding balls are placed inside a storage cylinder, and the storage cylinder is rotated by a first motor, so that the raw material can be well pulverized. After pulverization, the raw material is sieved to obtain fused quartz sand with a particle size of 40 - 200 mesh. Then, through pickling and magnetic separation, high-purity fused quartz sand is obtained. Then, it is pulverized by a jet mill to obtain high-purity fused silica powder with a D50 of 1 - 50 μm. However, in the actual use process, since the pulverized raw material needs to be taken out from the inside of the storage cylinder, and the inlet and outlet of the storage cylinder are arranged inside the storage cylinder, it is rather troublesome to take out the pulverized raw material from the inside of the storage cylinder. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks existing in the prior art, and to provide an apparatus and method for recycling waste quartz crucibles to prepare high-purity fused silica powder.

A discharging device is arranged on one side of the storage cylinder, and a rotating device is arranged inside the storage cylinder. The discharging device includes an electric telescopic rod. A first connecting groove is opened on one side of the support frame, and the top of the first connecting groove is fixedly connected with the bottom of the electric telescopic rod. A first groove is opened at the top of the first connecting groove, and a rotating roller is rotatably inserted into the inner wall of the first groove. The top of the electric telescopic rod is fixedly connected with the surface of the rotating roller.

[0008] The effects achieved by the above components are as follows: The connecting frame is extruded by the first spring in a direction away from the storage groove, so that the connecting frame slides out of the interior of the storage groove, and the limiting plate is moved away from the interior of the storage cylinder near the end of the connecting plate. Then, manually control the rotation of the bolt, so that the bolt presses against one side of the connecting frame, which can well limit the connecting frame inside the storage groove, and further move the limiting plate away from the interior of the storage cylinder near the end of the connecting plate.

[0009] Preferably, a circular groove is formed on the surface of the limiting plate. A rubber ring is arranged on the inner wall of the circular groove. Second springs are uniformly and fixedly connected to the inner wall of the circular groove. One end of the second spring away from the circular groove is fixedly connected to one side of the rubber ring close to the circular groove.

[0010] The effects achieved by the above components are as follows: The rubber ring is extruded by the second spring in a direction away from the circular groove, so that the side of the rubber ring away from the circular groove is pressed against the inner wall of the storage cylinder, which can well make the limiting plate closely adhere to the interior of the storage cylinder.

[0011] Preferably, a sliding groove is formed on the inner wall of the limiting plate. A connecting rope is slidably connected to the inner wall of the sliding groove.

[0013] Preferably, a plurality of arc plates are uniformly and fixedly connected to one side of the limiting plate close to the storage cylinder. A support plate is fixedly connected to one side of the arc plate close to the limiting plate. A clamping groove is formed in one side of the arc plate close to the limiting plate.

[0014] The effects achieved by the above components are as follows: Manually place the filter screen between the extrusion plate and the clamping plate. The third spring squeezes the clamping plate away from the clamping groove, and then the fourth spring squeezes the extrusion plate away from the support plate, and then the extrusion plate and the clamping plate clamp the filter screen. In this way, screening can be carried out while pouring out the inside of the storage cylinder, and quartz stones of different specifications can be screened out by replacing the filter screen.

[0026] Refer to Figure 7 and Figure 8 , the rotating device 7 includes a rectangular plate 701, the rectangular plate 701 is fixedly connected to the inner wall of the storage cylinder 3, a circular plate 702 is fixedly connected to the middle of the rectangular plate 701, a circular rod 703 is rotatably inserted through one side of the circular plate 702, one end of the circular rod 703 is fixedly connected to a rotating block 704, and the surface of the rotating block 704 is uniformly fixedly connected with rotating blades 705. An arc surface 706 is opened on one side of the rotating blade 705. When using the rotating device 7, the rotating blade 705 fixed on the surface of the rotating block 704 is driven to rotate by controlling the circular rod 703. When the rotating blade 705 rotates, the arc surface 706 opened on the surface of the rotating blade 705 can lift the crushed quartz stones, so that it is convenient for the crushed quartz stones to pass through the filter screen 615. A fixing plate 708 is fixedly connected to the surface of the storage cylinder 3, a second motor 709 is fixedly connected to one side of the fixing plate 708, an output end of the second motor 709 is fixedly connected to a second pulley 710, a connecting belt 711 is sleeved on the surface of the second pulley 710, a first pulley 707 is arranged on the inner wall of the connecting belt 711, and one side of the first pulley 707 is fixedly connected to the end of the circular rod 703 far away from the rotating block 704. The second motor 709 drives the second pulley 710 to rotate, and then the circular rod 703 is driven to rotate through the connecting belt 711. A rectangular groove 712 is opened on the surface of the storage cylinder 3, the rectangular groove 712 is sleeved on the surface of the connecting belt 711, and a rubber frame 713 is fixedly connected to the inner wall of the rectangular groove 712. The rubber frame 713 is sleeved on the surface of the connecting belt 711. When the connecting belt 711 rotates, the rubber frame 713 presses on the surface of the connecting belt 711, and thus, to a certain extent, it is avoided that the crushed quartz stones fall out of the inside of the storage cylinder 3 through the rectangular groove 712.

[0027] Working principle: When preparing high-purity fused silica powder, the raw material, quartz crucible waste, is cleaned and dried to remove dust and debris on the surface. Then, the raw material and the grinding balls are placed inside the storage cylinder 3. Subsequently, the first motor 1 drives the storage cylinder 3 to rotate, which can effectively crush the raw material. After crushing, the raw material is screened to obtain fused quartz sand with a particle size of 40 - 200 mesh. Then, through pickling and magnetic separation, high-purity fused quartz sand is obtained. Next, it is crushed by a jet mill to obtain high-purity fused silica powder with a D50 of 1 - 50 μm. When using the discharging device 6, manually place the filter screen 615 between the extrusion plate 629 and the clamping plate 631. The third spring 633 squeezes the clamping plate 631 away from the clamping groove 630, and then the fourth spring 628 squeezes the extrusion plate 629 away from the support plate 626. Thus, the filter screen 615 is clamped by the extrusion plate 629 and the clamping plate 631. This enables screening while pouring out the material inside the storage cylinder 3, and different specifications of quartz stones can be screened by replacing the filter screen 615. Then, manually control the clamping block 620 to move away from the middle of the two clamping blocks 620, and then pull the connecting rope 619 away from the storage cylinder 3. Consequently, control the connecting rope 619 to pull the rubber ring 624 towards the inside of the circular groove 623, which can effectively confine the rubber ring 624 inside the circular groove 623. This facilitates sliding the limiting plate 609 out of the inner wall of the storage cylinder 3. The first spring 613 squeezes the connecting frame 610 away from the receiving groove 611, causing the connecting frame 610 to slide out of the receiving groove 611 and the limiting plate 609 to move away from the inside of the storage cylinder 3 near the connecting plate 4. Then, manually control the bolt 617 to rotate, and the bolt 617 squeezes against one side of the connecting frame 610, effectively confining the connecting frame 610 inside the receiving groove 611 and causing the limiting plate 609 to move away from the inside of the storage cylinder 3 near the connecting plate 4. The electric telescopic rod 602 squeezes the rotating roller 604 away from the ground, driving the rotating roller 604 to rotate inside the first groove 603, which in turn drives the rotating plate 608 to rotate inside the second groove 606, forming a certain angle for the storage cylinder 3. Slide the limiting plate 609 out of the inner wall of the storage cylinder 3 near the connecting plate 4, which can effectively pour out the crushed raw material inside the storage cylinder 3, facilitating the discharging of the storage cylinder 3. When using the rotating device 7, the second motor 709 drives the second pulley 710 to rotate, and then the connecting belt 711 drives the round rod 703 to rotate. By controlling the round rod 703, the rotating blades 705 fixed on the surface of the rotating block 704 are driven to rotate. When the rotating blades 705 rotate, the arc surface 706 formed on the surface of the rotating blades 705 can lift the crushed quartz stones, facilitating the crushed quartz stones to pass through the filter screen 615. When the connecting belt 711 rotates,The rubber frame 713 is extruded on the surface of the connecting band 711, thereby to a certain extent preventing the crushed quartz stone from falling out of the interior of the storage cylinder 3 through the rectangular groove 712.,

[0028] It should be noted that all the damping rods in this case are telescopic dampers, which can absorb energy during the telescopic process.
