Description
Technical Field
[0001] This utility model relates to the field of fused silica processing technology, and in particular to an environmentally friendly acid washing device for fused silica. Background Technology
[0002] Fused silica is a high-purity amorphous silicon material with excellent chemical stability, high-temperature performance, and light transmittance, making it widely used in semiconductors, optical devices, precision casting, and chemical containers. However, during the processing and use of fused silica, its surface often becomes contaminated with metal ions, particulate impurities, and organic matter. These impurities significantly affect its purity and performance, thus reducing product quality and effectiveness. To remove surface contaminants and ensure the purity of fused silica, surface cleaning using acid pickling equipment is typically required. The acid pickling process effectively removes adhering impurities while maintaining the integrity of the fused silica itself, making it a crucial step in improving product performance.
[0003] Currently, acid cleaning devices for fused silica cleaning mainly employ immersion or spraying methods for surface cleaning. Immersion devices remove surface impurities by immersing fused silica in acid solution and using chemical reactions. However, the sample is usually stationary during the cleaning process, resulting in limited coverage and penetration of the acid solution on the surface, and it is easy to create cleaning dead zones in the recessed areas or complex regions of the sample. Although spraying devices can improve cleaning efficiency to some extent by spraying acid solution onto the sample surface through high-pressure nozzles, the uniformity of cleaning coverage is poor, and it is difficult to flexibly adjust the operating mode according to actual needs, resulting in unstable cleaning effects. Therefore, an environmentally friendly acid cleaning device for fused silica is proposed to solve the above problems. Utility Model Content

[0029] 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.
[0030] Reference Figures 1-3This utility model provides an embodiment of an environmentally friendly pickling device for fused silica, comprising a pickling tank 1, an electric telescopic rod 2 installed on the side wall of the pickling tank 1, a top plate 3 fixedly connected to the output end of the electric telescopic rod 2, a shaking mechanism installed at the bottom of the top plate 3, and a cleaning mechanism installed inside the pickling tank 1; the shaking mechanism includes a motor 4, which is installed at the top of the top plate 3, and the output end of the motor 4 passes through the top plate 3 and is fixedly connected to a turntable 5; a limit post 10 is installed at the bottom of the turntable 5, and a fixing block 11 is fixedly connected to the bottom of the turntable 5. 11 has a sliding rod 12 internally connected, a sliding frame 13 fixedly connected between the sliding rods 12, a limiting post 10 slidably connected inside the sliding frame 13, a placement rack 14 fixedly connected to the bottom of the sliding rod 12, a placement box 15 is provided inside the placement rack 14, an adjustment frame 6 fixedly connected to the bottom of the turntable 5, a slider 7 slidably connected inside the adjustment frame 6, a rubber sheet 9 fixedly connected to the top of the limiting post 10, a bolt 8 fixedly connected to the top of the rubber sheet 9, the bolt 8 is threadedly connected inside the slider 7, and the rubber sheet 9 is in contact with the lower surface of the adjustment frame 6;
[0031] When using this equipment, the fused silica material to be pickled must first be placed inside the placement box 15 and then placed in the placement rack 14. Next, the electric telescopic rod 2 is activated, causing the top plate 3 to move downwards, gradually pushing the placement box 15 into the pickling tank 1 until it is completely placed inside. After the fused silica is placed in the pickling tank 1, the motor 4 is activated to drive the turntable 5 to rotate. The rotation of the turntable 5 causes the limiting post 10 connected to its bottom to move in a circular motion, which in turn drives the sliding frame 13 to move accordingly. Since the sliding frame 13 is restricted by the fixed block 11, its movement can only be left and right back and forth. Therefore, the placement box 15 will also sway left and right in the pickling tank 1. This left and right swaying motion can effectively increase the clarity of the fused silica in the pickling solution. The cleaning surface is thoroughly and evenly cleaned to improve cleaning effectiveness and avoid dead zones. When adjusting the swaying amplitude of the placement box 15 during pickling, the limiting post 10 can be twisted to move the bolt 8 downwards. This movement causes the rubber sheet 9 to gradually separate from the adjusting frame 6, causing the slider 7 to lose its original restraining function. In this case, sliding the slider 7 changes the distance between it and the center of the turntable 5. By adjusting this distance, the swaying amplitude of the placement box 15 can be flexibly controlled. The farther the slider 7 is from the center, the greater the swaying amplitude, and vice versa. After adjusting the swaying amplitude, the bolt 8 is twisted in the opposite direction to re-attach the rubber sheet 9 to the adjusting frame 6, locking the slider 7 in place and ensuring that the adjusted swaying amplitude remains stable during cleaning. This method allows for adjusting the swaying amplitude of the placement box 15 according to different pickling requirements, further improving the efficiency and effectiveness of fused silica cleaning.
[0032] Reference Figure 2 and Figure 4 The cleaning mechanism includes a waste trough 16, which is slidably connected inside the pickling tank 1. The waste trough 16 is located at the bottom of the placement rack 14. A filter screen 19 is slidably connected inside the waste trough 16. A crossbar 17 is fixedly connected inside the waste trough 16. A sliding block 18 is slidably connected to the side wall of the crossbar 17. The sliding block 18 is fixedly connected to the bottom of the placement rack 14.
[0033] As the placement rack 14 sways left and right inside the pickling tank 1, its bottom slides along the top of the waste tank 16 via the sliding block 18. Because the placement rack 14 moves the molten silica inside during the swaying process, impurities generated during the cleaning process are effectively stripped off and fall into the waste tank 16, which collects the impurities. After the molten silica cleaning is completed, the electric telescopic rod 2 is activated, causing the top plate 3 to gradually move upwards. The rise of the top plate 3 lifts the placement rack 14 out of the pickling tank 1, simultaneously moving the waste tank 16 upwards as well. The upward movement of the waste tank 16 allows the waste tank 16 to be cleaned and removed from the pickling tank 1. Before discharging the contaminated liquid, the deposited impurities are removed from the pickling tank 1 to prevent them from being discharged with the liquid during the pickling process. This prevents environmental pollution or interference with subsequent processing steps. After the waste tank 16 is completely removed from the pickling tank 1, the operator can pull out the filter screen 19 from the waste tank 16 to clean the collected impurities. This method reduces the difficulty of cleaning and improves the convenience and efficiency of equipment use. In addition, the presence of the waste tank 16 not only reduces secondary pollution from impurities during the pickling process but also simplifies subsequent cleaning steps, avoiding repeated contamination of the pickling solution or increased equipment maintenance costs due to residual impurities.
[0034] Working principle: When using this equipment, first place the fused silica to be pickled inside the placement box 15 and then place it in the placement rack 14. Then, start the electric telescopic rod 2 to move the top plate 3 downwards, so that the placement box 15 is completely placed inside the pickling tank 1. At this time, start the motor 4 to drive the turntable 5 to rotate, so that the limiting post 10 connected to its bottom moves in a circular motion, and further drives the sliding frame 13 to move. Because the sliding frame 13 is restricted by the fixed block 11, the sliding frame 13 can only sway left and right, so that the fused silica to be pickled is placed inside the pickling tank 1. The placement box 15 is swayed left and right in the pickling box 1 to achieve the effect of thoroughly cleaning the fused quartz. When it is necessary to adjust the swaying amplitude of the placement box 15, the limit post 10 can be twisted to move the bolt 8 downward, causing the rubber sheet 9 to separate from the adjustment frame 6, so that the slider 7 is no longer restricted. Then, the distance between the slider 7 and the center of the turntable 5 can be changed by sliding the slider 7. After the adjustment is completed, the bolt 8 is rotated in the opposite direction to make the adjustment frame 6 and the rubber sheet 9 fit together again, and the position of the slider 7 is locked, thereby completing the adjustment of the swaying amplitude of the placement box 15.
[0035] While the placement rack 14 is shaking inside the pickling tank 1, it slides on top of the waste tank 16 via the sliding block 18. The impurities generated by the shaking fall into the waste tank 16. After the fused silica is cleaned, the electric telescopic rod 2 is activated to lift the top plate 3 upward, and simultaneously moves the placement rack 14 and the waste tank 16 upward. As the waste tank 16 moves upward, it will remove the impurities inside the pickling tank 1, preventing contamination when the liquid inside the pickling tank 1 is discharged later. After the waste tank 16 is removed from the pickling tank 1, the filter screen 19 can be pulled out from the waste tank 16 to clean the removed impurities, reducing the cleaning difficulty and improving work efficiency.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
