Description

Technical Field

[0001] This utility model relates to the technical field of quartz glass processing equipment, and in particular to a paraffin cleaning device for quartz glass surface. Background Technology

[0002] Quartz glass has an extremely low coefficient of thermal expansion, high temperature resistance, excellent chemical stability, good electrical insulation, low and stable ultrasonic delay performance, optimal ultraviolet spectral transmission performance, as well as visible and near-infrared spectral transmission performance, and mechanical properties that are superior to those of ordinary glass.

[0003] Currently, quartz glass prepared by chemical vapor deposition (CVD) is mostly 150mm~400mm in diameter and 700mm~2500mm in length, which are relatively large in size and weight. Furthermore, during storage and transportation, the surface of quartz glass is usually covered with a layer of paraffin wax, which needs to be removed beforehand in subsequent processing.

[0004] However, due to the large size and weight of quartz glass, at least three people are needed to complete the cleaning process. Furthermore, to remove the paraffin layer from the surface of the quartz glass, a high-temperature cleaning liquid (temperature greater than 80°C) is required, posing a risk of burns.

[0033] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0034] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0035] Figure 1 This is a front view of the paraffin cleaning device for the quartz glass surface in the embodiment. Figure 2 This is a right view of the paraffin cleaning device for the quartz glass surface in the embodiment. Figure 3 for Figure 2 Sectional view along the AA direction. Figure 4 This is a schematic diagram of the quartz glass surface paraffin cleaning device in the embodiment with the lid closed. Figure 5 This is a schematic diagram showing the quartz glass surface paraffin cleaning device in the embodiment with the lid open, where the quartz glass is not shown. Figures 1-5As shown, the quartz glass surface paraffin cleaning device includes a rectangular box 100 and a matching lid 200. One edge of the lid 200 is connected to the corresponding edge of the box 100 by a hinge, so that the lid 200 can be deflected and opened with the hinge (not shown in the figure) as the hinge point. When the lid 200 is closed, the area formed by the lid 200 and the box is the horizontal (i.e., the axial direction of the quartz glass is roughly horizontal) cleaning area for the quartz glass.

[0036] Figure 6 This is a three-dimensional structural view of the housing of the paraffin cleaning device for quartz glass surfaces in the embodiment. Figure 1 ~and Figures 4-6 As shown, adjustable feet 110 are provided near the four corners of the bottom outer side of the cabinet 100. The adjustable feet 110 can be used to roughly adjust the horizontal state of the cabinet 100, which helps to keep the quartz glass in a horizontal position and reduce tilting and sliding. At the same time, a drain port 130 is provided at the bottom of the cabinet 100, through which high-temperature cleaning liquid (temperature greater than 80°C) or clean water inside the cabinet 100 can be released. Two first support rollers 120 are arranged along their length near the bottom inner side of the housing 100. Each first support roller 120 consists of a roller shaft and a plastic sleeve covering the roller shaft. The two ends of the roller shaft pass through the side wall of the housing 100 and are equipped with corresponding sealing structures. Since the diameter of the quartz glass is approximately 150mm to 400mm, the maximum distance between the surfaces of the two first support rollers 120 is 140mm to ensure the quartz glass is placed between them; that is, the maximum distance between the surfaces of the two first support rollers 120 is less than the diameter of the quartz glass. Simultaneously, the two first support rollers 120 can achieve equal-speed, opposite-rotation under the action of a drive mechanism (such as a motor) located outside the housing 100. It should be noted that the two first support rollers 120 can be driven separately by one drive mechanism, or simultaneously by one drive mechanism in conjunction with a corresponding gear set. This technique is conventional in the field and can be implemented without creative effort.

[0037] like Figure 2 and Figure 3As shown, a hydraulic cylinder 210 is provided in the middle of the upper surface of the cover 200 (the side surface facing the outside of the box body 100), and the piston rod 211 of the hydraulic cylinder 210 extends to the lower surface of the cover 200 in a direction perpendicular to the cover 200. Meanwhile, an arc-shaped plate 220 with a hollow interlayer is provided at the free end of the piston rod 211; the length direction of the arc-shaped plate 220 is approximately parallel to the length direction of the first support roller 120, and its length is greater than the length of the effective support area of ​​the first support roller 120 (i.e., the axial length of the plastic sleeve); when the box cover 200 and the box body 100 are closed, the arc-shaped plate 220 is located directly above the area between the two first support rollers 120, the inner wall of the arc-shaped recess of the arc-shaped plate 220 faces the bottom surface of the box body 100, and the radius of curvature of the arc-shaped plate 220 is greater than or equal to the radius of the quartz glass; at the same time, several injection holes (not shown in the figure) are opened on the inner wall of the arc-shaped recess of the arc-shaped plate 220, and the diameter of the injection holes is 0.5~2mm. A through hole 230 is also provided on the cover 200. A connecting pipe 221 is also inserted through the through hole 230. The diameter of the connecting pipe 221 is smaller than the diameter of the through hole 230. At the same time, a four-way connector 222 is provided at one end of the connecting pipe 221, and the other end of the connecting pipe 221 is connected to the hollow interlayer of the arc plate 220. Of the remaining three passages of the four-way connector 222, one is connected to the high-temperature cleaning fluid supply pipeline, one is connected to the clean water supply pipeline, and one is connected to the hot air supply pipeline.

[0038] When cleaning quartz glass using the paraffin cleaning device in this embodiment, the quartz glass is first hoisted into the housing 100 and placed horizontally and stably within the two first support rollers 120. Then, the housing cover 200 is closed, and the hydraulic cylinder 210 is activated, causing the piston rod 211 to drive the arc-shaped plate 220 towards the top area of ​​the quartz glass. The plate eventually stops at a distance of 1-2 cm between the highest point of the quartz glass and a corresponding point on the inner wall of the arc-shaped recess of the vertically corresponding arc-shaped plate 220. Finally, high-temperature cleaning fluid, clean water, and hot air are sequentially injected into the housing 100 through the high-temperature cleaning fluid supply pipeline, the clean water supply pipeline, and the hot air supply pipeline, and sprayed at high speed from the spray holes on the arc-shaped plate 220. This cleans and dries the quartz glass, which is rolling synchronously with the two first support rollers 120, removing the paraffin layer adhering to its surface. When the high-temperature cleaning fluid or clean water in the housing 100 covers the quartz glass to its upper limit, the drain port 130 can be opened intermittently to discharge the fluid.

[0039] The paraffin cleaning device for quartz glass surfaces in this embodiment can save some manpower; at the same time, the cleaning process is carried out within the combined structure of the box and the lid, and no human operation is required during the cleaning process. Therefore, the operator will not actively come into contact with the high-temperature cleaning liquid, greatly reducing the risk of burns; in addition, during the cleaning process, the curved plate is close to the quartz glass, and the impact of the high-temperature cleaning liquid, water and hot air on the surface of the quartz glass is greater, and it can cooperate with the support roller to prevent the quartz glass from falling off.

[0040] Furthermore, in this embodiment, to prevent the quartz glass from moving axially on the two first support rollers 120, a limiting ring plate 121 is provided at one end of one first support roller 120, and a limiting ring plate 121 is also provided at the other end of the other first support roller 120; the two limiting ring plates 121 can limit the quartz glass from both axial ends. It should be noted that the two limiting ring plates 121 can also be provided at both ends of the same first support roller 120, or the two first support rollers 120 can each have a limiting ring plate 121 at both ends. That is to say, the quartz glass surface paraffin cleaning device includes at least two limiting ring plates 121, and at least one limiting ring plate 121 is provided at each opposite end of the two first support rollers 120.

[0041] Furthermore, in this embodiment, since quartz glass is relatively heavy and prone to bending and deformation of the first support roller 120, at least one auxiliary support assembly is provided below each first support roller 120. The auxiliary support assembly includes a roller 122 and a support seat 123. The support seat 123 is approximately perpendicular to the bottom surface of the housing 100, and its top has a U-shaped mounting groove. The roller 122 is disposed in the U-shaped mounting groove, and the rolling center of the roller 122 is parallel to the axial center of the corresponding first support roller 120. The top of the roller 122 makes rolling contact with the bottom of the first support roller 120. In this embodiment, the auxiliary support assembly can provide good auxiliary support for the first support roller 120 to ensure reliable operation.

[0042] Furthermore, in this embodiment, to prevent the quartz glass from accidentally rolling off the two first support rollers 120, a second support roller (not shown in the figure) is provided on each side of the two first support rollers 120. The structure of the second support roller is the same as that of the first support roller 120, but it does not require a drive to rotate. The maximum distance between the second support roller and the adjacent first support roller 120 is less than the diameter of the quartz glass. At the same time, the two first support rollers 120 and the two second support rollers are approximately located in the same horizontal plane. Therefore, even if the quartz glass rolls off the two first support rollers 120, there will not be a large height difference.

[0043] Furthermore, in this embodiment, several silicone protrusions (not shown in the figure) are provided on the inner wall of the arc-shaped recess of the arc plate 220, and the height of the silicone protrusions is 1~2mm. In this embodiment, the silicone protrusions can prevent the quartz glass from directly contacting the arc plate 220 under abnormal conditions (such as when the quartz glass rolls out between the two first support rollers 120), thus avoiding wear of the quartz glass.

[0044] Furthermore, in this embodiment, to reduce the amount of high-temperature cleaning fluid and clean water used and improve their utilization rate, the quartz glass surface paraffin cleaning device also includes a buffer tank, a circulation pump, a filter, and a booster pump (not shown in the figure); an electric heater 300 is installed inside the buffer tank. Simultaneously, an external circulation interface pipe 140 is also provided at the bottom of the tank 100. The external circulation interface pipe 140 is connected to the circulation pump, drawing high-temperature cleaning fluid or clean water from the tank 100, pumping it into the filter for filtration, and then flowing into the buffer tank, where it is heated by the electric heater 300 (this can be disabled during clean water cleaning) to maintain the appropriate temperature. Finally, the booster pump draws high-temperature cleaning fluid or clean water from the buffer tank, pressurizes it, and pumps it into the arc-shaped plate 220 for high-speed spraying. Alternatively, in this embodiment, an electric heater 300 is installed inside the tank 100, such as... Figure 6 As shown in the diagram, an external circulation interface pipe 140 is also provided at the bottom of the housing 100. The quartz glass surface paraffin cleaning device also includes a filter and a booster pump. The external circulation interface pipe 140 is connected to the filter, and the booster pump uses suction to draw out the high-temperature cleaning fluid or clean water from inside the housing 100, which is then filtered and pumped into the arc-shaped plate 220 for high-speed spraying.
