Description

Technical Field

[0001] The invention relates to the technical field of quartz tube production, in particular to a defect removal sandblasting device for quartz tube production and a use method thereof. Background Art

[0002] Quartz tube is a transparent tubular material made of high-purity silicon dioxide (SiO2). Due to its unique physical and chemical properties, it is widely used in many fields.

[0003] During the production process of quartz tubes, scratches, stains or other surface defects may remain on the surface, which will affect the processing of subsequent processes of the quartz tubes. Therefore, the surface of the quartz tubes needs to be sandblasted, and the roughness of the surface of the quartz tubes needs to be changed at the same time to enhance the adhesion of subsequent processes such as bonding and painting, and to make preliminary preparations and pretreatments for coating, welding or sealing. Sandblasting can provide a clean substrate suitable for bonding, but the existing sandblasting device usually sandblasts the surface of the quartz tube through a single nozzle, and rotates the quartz tube during the sandblasting process to keep the surface roughness of the quartz tube uniform. However, during the sandblasting process, the single-sided sandblasting method is prone to uneven sandblasting, resulting in uneven surface roughness of the quartz tube, which affects subsequent processing steps. At the same time, a large amount of dust floats inside the quartz tube after sandblasting, which easily pollutes the working environment. Summary of the invention

[0030] The embodiment of the present invention provides a defect removal sandblasting device for quartz tube production and a method for using the device, which is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0031] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Example 1 See also Figure 1-Figure 10 In the embodiment, a defect removal sandblasting device for quartz tube production provided in the present invention comprises: a box body 1, a vacuum box 2 is installed on the top of the box body 1, a workbench 101 is installed inside the box body 1, a device block 5 is installed on the top of the workbench 101, a storage cavity 3 is opened inside the device block 5, an annular block 9 is provided inside the box body 1, a plurality of openings 902 are opened inside the annular block 9, and nozzles 903 are installed inside the openings 902, and an adjusting block 10 is installed on the top of the workbench 101; a discharge component arranged between the vacuum box 2 and the storage cavity 3, for uniformly discharging the sprayed material; a sandblasting component arranged between the box body 1 and the annular block 9, for sandblasting the surface of the quartz tube; and a fixing component arranged inside the box body 1, for fixing the quartz tube.

[0033] Among them, through the setting of the sandblasting component, the surface of the quartz tube can be evenly sandblasted to remove scratches, stains or other surface defects on the surface of the quartz tube, ensuring that the surface roughness of the quartz tube is uniform; secondly, with the setting of the discharge component, on the one hand, the dust floating inside the box 1 can be extracted for filtering, and on the other hand, the gas flow generated during the exhaust process can be used to drive the auger 409 to rotate, so that the spray material is discharged evenly, avoiding the influence of too much or too little spray material on the sandblasting effect; then, through the setting of the fixing component, one end of the quartz tube can be quickly clamped and fixed, and the quartz tube can be clamped and fixed in the horizontal direction by the clamping plate 701 and the adjustment block 10, so as to further improve the stability of the quartz tube during the sandblasting process, and avoid the position displacement of the quartz tube during the sandblasting process and affect the sandblasting defect removal effect.

[0034] Example 2 On the basis of Example 1, the discharge assembly includes: a transmission chamber 302 opened inside the equipment block 5, and a transmission rod 406 is rotatably connected to the transmission chamber 302 through a bearing; an air outlet pipe 203 opened on one side of the vacuum box 2, and a rotating groove 204 is opened on the inner wall of the air outlet pipe 203; a rotating rod rotatably connected to the rotating groove 204, a plurality of rotating plates 401 with an arc-shaped structure are connected to the outer side of the rotating rod, and some rotating plates 401 are located in the air outlet pipe 203, and a driving wheel 4 is fixedly connected to the rotating rod; a rotating rod rotatably connected to the transmission chamber 302 through a bearing, and a driven wheel 403 is fixedly connected to the rotating rod, and a transmission belt 402 is connected between the driving wheel 4 and the driven wheel 403; a discharge pipe 303 opened inside the equipment block 5, and a screw dragon 409 is provided inside the discharge pipe 303.

[0035] Among them, a detachable filter screen 201 is provided inside the vacuum box 2, and a T-shaped vacuum pipe 205 is connected to the bottom of the vacuum box 2, and a plurality of vacuum holes 206 are opened at the bottom of the vacuum pipe 205. The internal space of the vacuum box 2 near the air outlet pipe 203 is funnel-shaped, and an exhaust fan 202 is installed inside the vacuum box 2. One end of the rotating rod is connected to the first transmission wheel 404, and the end of the transmission rod 406 close to the first transmission wheel 404 is connected to the second transmission wheel 405, and the second transmission wheel 405 is meshed with the first transmission wheel 404. The other end of the transmission rod 406 is connected to the third transmission wheel 407, and the top of the auger 409 is connected to the fourth transmission wheel 408 meshed with the third transmission wheel 407, and the top of the box body 1 is connected to the feed pipe 301.

[0036] During the sandblasting process of the quartz tube, a large amount of floating dust appears inside the box 1 due to the high-pressure gas carrying a large amount of spray material being sprayed onto the surface of the quartz tube and then rebounding. After the sandblasting is completed, the floating dust inside the box 1 is easy to diffuse outward and pollute the working environment. Therefore, the gas inside the exhaust box 2 can be discharged to the outside through the exhaust pipe 203 by the exhaust fan 202. At this time, the air pressure inside the exhaust box 2 drops. At this time, the gas inside the box 1 is sucked into the exhaust box 2 through the exhaust pipe 205 and the exhaust hole 206, and the dust in the gas is filtered through the filter 201 to reduce the situation of crushing and polluting the working environment. Then, since the internal space of the vacuum box 2 near the air outlet pipe 203 is funnel-shaped, the flow rate of the gas inside the vacuum box 2 increases when passing through the air outlet pipe 203, so that the gas in the air outlet pipe 203 can quickly drive the rotating plate 401 to rotate, and the rotating plate 401 drives the driving wheel 4 to rotate through the rotating rod. At this time, the driving wheel 4 drives the driven wheel 403 through the transmission belt 402, and then the driven wheel 403 drives the first transmission wheel 404 to rotate through the rotating rod. At this time, the first transmission wheel 404 drives the fourth transmission wheel 408 to rotate through the second transmission wheel 405, the transmission rod 406, and the third transmission wheel 407, thereby driving the auger 409 to rotate, so that the spray material in the storage chamber 3 can be evenly discharged into the cavity 501 by the auger 409, avoiding too much or too little spray material discharged, thereby affecting the effect of sandblasting on the quartz tube.

[0037] Example 3 On the basis of Example 1, the sandblasting assembly includes: an air compressor 6 installed inside the equipment block 5, with conduits connected on both sides of the air compressor 6, a cavity 501 communicating with the conduit is opened inside the equipment block 5, and a delivery pipe 502 is connected to one side of the cavity 501; a motor 8 installed inside the equipment block 5, a threaded rod 801 is drivingly connected to one side of the motor 8, a moving block 802 is threadedly connected to the threaded rod 801, a connecting pipe 804 is connected to the bottom of the moving block 802, and a blocking block 805 is connected to the bottom of the connecting pipe 804, and the bottom of the blocking block 805 is connected to the annular block 9, a limiting rod is installed inside the box body 1, and a limiting hole matching the limiting rod is opened on the moving block 802, a fixed pipe 503 communicating with the delivery pipe 502 is connected to one side of the equipment block 5, and an air pipe 803 is connected to one end of the fixed pipe 503, and the air pipe 803 is close to the outer surface of the moving block 802.

[0038] When the quartz tube is sandblasted, the external gas can be compressed by the air compressor 6 and then transported to the inside of the cavity 501, and the compressed gas carries the spray material in the cavity 501 into the delivery pipe 502, and enters the connecting pipe 804 through the fixed pipe 503 and the air pipe 803, and then transported to the annular pipe 901 through the connecting pipe 804, and sprayed out through multiple nozzles 903. By setting up multiple nozzles 903, the surface of the quartz tube can be sandblasted in all directions at the same time, without the need to rotate the quartz tube, thereby ensuring the effect of sandblasting and removing defects from the quartz tube.

[0039] Then, during the sandblasting process, the threaded rod 801 is driven to rotate by the motor, and the threaded rod 801 is threadedly connected to the moving block 802, so that when the threaded rod 801 rotates, the moving block 802 is driven to move, and then the annular block 9 is driven to move, and the surface of the quartz tube is sandblasted. The moving direction of the moving block 802 can be limited by the setting of the limit rod and the limit space.

[0040] Furthermore, one end of the air pipe 803 is communicated with the connecting pipe 804, an annular tube 901 is opened inside the annular block 9, and the connecting pipe 804 is communicated with the annular tube 901, a blocking groove 806 communicated with the connecting pipe 804 is opened inside the blocking block 805, a blocking block 807 is slidably connected inside the blocking groove 806, a blocking plate 8071 is connected to one side of the blocking block 807, a slot 8061 communicated with the blocking groove 806 is opened inside the blocking block 805, a limiting block 8062 is slidably connected inside the slot 8061, the limiting block 8062 is connected to the blocking block 807, a limiting spring 8063 is connected between the limiting block 8062 and the slot 8061, and a top block 115 is connected to one side of the adjusting block 10.

[0041] When the moving block 802 moves to be close to the adjusting block 10, the top block 115 on the adjusting block 10 is inserted into the blocking groove 806, and pushes the blocking block 807 and the blocking plate 8071 to move, so that the blocking plate 8071 blocks the connecting pipe 804, thereby stopping the sandblasting operation, and preventing the annular block 9 from moving back and forth on the quartz tube once and stopping on the adjusting block 10, and the staff forgets to turn off the air compressor 6, causing the multiple nozzles 903 on the annular block 9 to continue to sandblast the part of the quartz tube close to the adjusting block 10, resulting in different roughness of the surface of the quartz tube, and even affecting the diameter of the outer surface of the quartz tube; When the moving block 802 moves away from the adjusting block 10, the top block 115 separates from the blocking block 807. At this time, the blocking block 807 rebounds under the action of the elastic force of the limit block 8062 and the limit spring 8063, and then the blocking plate 8071 is retracted into the blocking groove 806, thereby opening the connecting pipe 804, so that the high-pressure gas and the spray can reach the nozzle 903 through the annular tube 901.

[0042] Example 4 On the basis of Example 1, the fixing component includes: two electric push rods 7 installed inside the equipment block 5, one side of the electric push rods 7 is connected to a clamping plate 701, and the clamping plate 701 is located above the workbench 101; an adjustment cavity 11 is opened inside the adjustment block 10, and an adjustment block 111 is rotatably connected to the inside of the adjustment cavity 11 through a bearing, and the adjustment block 111 is provided with two sections of threads in opposite directions; two arc-shaped clamping blocks 113 are arranged on one side of the adjustment block 10, a limiting groove 114 is opened on one side of the adjustment block 10, an adjustment plate 112 is connected to one side of the clamping block 113, and the adjustment plate 112 extends into the adjustment cavity 11 through the limiting groove 114, and a threaded hole matching the adjustment block 111 is opened on the adjustment plate 112.

[0043] Due to the scratches, stains or other surface defects left in the production process of the quartz tube, it is necessary to sandblast the surface of the quartz tube to remove the surface defects. At this time, one end of the quartz tube is placed on one side of the adjusting block 10 and between the two clamping blocks 113, and then the adjusting block 111 is rotated so that the adjusting block 111 drives the two adjusting plates 112 to move toward the quartz tube through the threaded hole, and clamps and fixes the quartz tube. Then, the clamping plate 701 is pushed to move toward the quartz tube through the electric push rod 7, so that the clamping plate 701 and the adjusting block 10 are used in coordination to clamp and fix the quartz tube in the horizontal direction, further improving the stability of the quartz tube during sandblasting, avoiding the quartz tube from being affected by the airflow or the impact of the spray material during the sandblasting process and rotating or shifting in position, or even falling, effectively ensuring the smooth progress of the sandblasting defect removal process of the quartz tube.
