Description

Technical Field

[0001] This utility model relates to the technical field of quartz glass tube processing equipment, and in particular to a hydrofluoric acid pickling rack for quartz glass tubes. Background Technology

[0002] After production, quartz glass tubes need to be acid-washed with hydrofluoric acid to remove surface impurities. In traditional operations, multiple quartz glass tubes are usually stacked densely in ordinary racks for immersion. In this method, due to the lack of effective isolation structures between the tubes, they are prone to collision and compression during hoisting, movement, or the impact of acid flow. Quartz glass is a highly brittle material, and surface scratches or microcracks will significantly reduce its mechanical properties and optical uniformity. This is especially true for quartz tubes used in high-precision instruments, where even minor damage can lead to product scrap.

[0003] While current pickling racks can achieve batch processing, they mostly use simple grids or general-purpose supports, whose support structures cannot simultaneously meet the dual requirements of securely isolating individual tubes and preventing damage from hard contact. For example, when using flat plates with perforated holes for fixing, the tubes are easily scratched by the edge of the holes during insertion; while simply placing them side by side cannot prevent the tubes from shaking and colliding.

[0004] Therefore, this utility model proposes a quartz glass tube hydrofluoric acid pickling rack to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology of quartz glass tube pickling racks, such as the lack of a targeted tube isolation structure, which leads to mutual collision damage of quartz glass tubes and low yield during the pickling process, this utility model aims to provide a quartz glass tube hydrofluoric acid pickling rack with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a hydrofluoric acid pickling rack for quartz glass tubes, comprising: a frame and a support assembly fixedly connected inside the frame, the support assembly including a reinforcing beam horizontally fixed to the inner wall of the frame and a support guide rod supported by the reinforcing beam; and an isolation assembly fitted onto the support guide rod, the isolation assembly including fixed spacers spaced at intervals along the length of the support guide rod, the fixed spacers having through holes and slots located on their upper edges.

[0007] The fixed spacer is slidably fitted onto the support guide rod through the through hole, so that the spacing is adjustable; the slot is an upward-opening arc-shaped groove used to radially constrain the quartz glass tube.

[0008] Furthermore, the supporting guide rod, the reinforcing crossbeam, and the fixed spacer form a triple stable structure: the reinforcing crossbeam provides horizontal rigid support, the supporting guide rod passes through the fixed spacer to form a sliding guide, and the fixed spacer vertically supports the quartz glass tube through the slot.

[0009] Preferably, the fixing spacer has a binding groove structure with a through-hole below it, which is used for ropes to pass through to bind and reinforce the fixing spacer and the support guide rod, thereby solving the risk of displacement caused by hoisting vibration.

[0010] Preferably, it also includes a fixed connecting rod connecting adjacent fixed spacers, with both ends of the rod fixed to the side wall of the fixed spacer, forming a truss structure that enhances the overall structure.

[0011] Preferably, lifting lugs are fixedly installed on the top of the frame, symmetrically distributed on both sides of the top beam of the frame, for connecting the hooks of lifting equipment to realize the overall lifting and transportation of the pickling rack.

[0012] Preferably, the bottom of the frame is fixedly provided with support feet, which are distributed at the four corners of the frame to provide stable ground support for the device when it is not hoisted.

[0013] Preferably, the radius of curvature of the arc contour of the slot is adapted to the tolerance of the outer diameter of the quartz glass tube to be processed, so as to achieve stress-free contact fixation of the tube surface.

[0014] Preferably, the support guide rod consists of two parallel metal rods whose axial direction is orthogonal to the length direction of the reinforcing beam, forming a double-track sliding platform.

[0015] Preferably, the support components and the main frame structure are both made of polypropylene material that is resistant to hydrofluoric acid corrosion.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem of damage caused by collisions and squeezing between quartz glass tubes during the existing pickling process by setting an isolation component with an independent slot for mounting quartz glass tubes and fitting it onto a support guide rod. It effectively isolates and stably supports each quartz glass tube, avoiding physical damage.

[0017] 2. This utility model solves the problems of cumbersome and unreliable fixing in the pickling rack tube installation process by using the sliding fitting of the isolation component on the support guide rod and adding a binding groove for fixing. It facilitates the adjustment of the spacing of the isolation component, makes tube installation flexible and efficient, and can achieve double fixing by rope binding to ensure the stable position of the quartz glass tube during pickling.

[0018] 3. This utility model solves the problem of easy deformation and unstable load-bearing of the pickling rack when it is hoisted under heavy load or immersed in acid by setting a support guide rod supported by a reinforced crossbeam in the frame, and supplementing it with support feet and lifting lugs at the top. It improves the structural strength and rigidity of the entire pickling rack and ensures safe and reliable load-bearing under hoisting and pickling conditions. Attached Figure Description

[0021] 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.

[0022] Please refer to Figures 1 to 4 This utility model provides a hydrofluoric acid pickling rack for quartz glass tubes, which aims to solve the problems in the prior art where the quartz glass tubes are not fixed stably and are easily damaged by collision and squeezing between the tubes.

[0023] like Figure 1 As shown, the quartz glass tube hydrofluoric acid pickling rack includes a frame 1 and a support assembly 2 fixedly connected inside the frame 1. The frame 1 serves as the load-bearing base for the entire device, providing an installation foundation for all other components. The support assembly 2 is used to support and position the isolation assembly 3. Specifically, the support assembly 2 includes a reinforcing beam 21 horizontally fixedly connected to the inner wall of the frame 1, and support guide rods 22 supported at both ends by the reinforcing beam 21. The pickling rack also includes the isolation assembly 3, such as... Figure 3 and Figure 4 As shown, the isolation assembly 3 includes fixed spacers 33 spaced apart along the length of the support guide rod 22. The fixed spacers 33 have through holes 31, which allow them to be slidably fitted onto the support guide rod 22. The upper edge of the fixed spacers 33 has a slot 34 for mounting quartz glass tubes.

[0024] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that the quartz glass tube hydrofluoric acid pickling rack also includes an isolation component 3, and the isolation component 3 and the aforementioned support component 2 form a specific structural fit and sliding connection relationship.

[0025] Please refer to the following carefully. Figure 3 and Figure 4 The core structure is described in detail below. The isolation component 3 includes fixed spacers 33 spaced at intervals along the length of the support guide rod 22. The upper edge of the fixed spacers 33 is integrally formed with multiple slots 34 for mounting quartz glass tubes. Each slot 34 is an upward-opening arc-shaped groove, and the outline size of the slot 34 is adapted to the outer diameter of the quartz glass tube. A through hole 31 is also provided on the fixed spacer 33 along its length. The diameter of the through hole 31 is adapted to the outer diameter of the support guide rod 22, so that the fixed spacer 33 can slide and fit through the through hole 31. In the assembled state, the fixing spacer 33 of the isolation component 3 passes through the through hole 31 onto the support guide rod 22 of the support component 2, forming a sliding fit structure. This sliding fit structure ensures that the fixing spacer 33 is not only easy to install, but its spacing on the support guide rod 22 can also be adjusted as needed. At the same time, a binding groove 32 is also provided on the fixing spacer 33 below the through hole 31. The binding groove 32 is used to bind the fixing spacer 33 to the support guide rod 22 with ropes, further enhancing the stability of the connection.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, such as Figure 3 and Figure 4 As shown, a binding groove 32 is provided on the fixed spacer 33 below the through hole 31. The binding groove 32 is a through groove or recess in the body of the fixed spacer 33, which is used for ropes or cable ties to pass through and bind the fixed spacer 33 to the support guide rod 22, thereby enhancing the stability of the isolation assembly 3 during hoisting and pickling and preventing it from sliding and shifting on the support guide rod 22.

[0027] In a preferred embodiment, the support assembly 2 further includes a fixed connecting rod 23, which is located between two adjacent fixed spacers 33. Its two ends are fixedly connected to the sides or specific connection points of the two fixed spacers 33, respectively. The fixed connecting rod 23 connects multiple fixed spacers 33 distributed along the support guide rod 22 into a stable overall structure, thereby improving the overall rigidity of the isolation assembly 3.

[0028] As a preferred embodiment, such as Figure 1As shown, the top of the frame 1 is fixedly connected with lifting lugs 4. The lifting lugs 4 are preferably set on the left and right sides of the top beam of the frame 1, symmetrically distributed, and are used to connect lifting equipment such as overhead cranes through hooks to realize the hoisting and transportation of the entire pickling rack.

[0029] As a preferred embodiment, such as Figure 1 and Figure 2 As shown, the bottom of the frame 1 is fixedly connected with support feet 5. There are usually multiple support feet 5, such as four, located at the four corners of the bottom of the frame 1, providing stable ground support for the entire pickling rack and allowing it to be placed stably when hoisted off the ground.

[0030] As a preferred embodiment, such as Figure 4 As shown, the slot 34 on the fixing strip 33 adopts an upward-opening arc-shaped groove structure, which can better fit the cylindrical outer wall of the quartz glass tube.

[0031] As a preferred embodiment, such as Figure 4 As shown, based on the use of an upward-opening arc-shaped groove, the radius of the arc-shaped groove is matched with the outer diameter of the quartz glass tube, that is, its radius is close to the radius of the quartz glass tube, ensuring that the quartz glass tube can be firmly stuck in the slot 34 and will not easily fall out, while avoiding stress concentration and damage caused by the slot 34 and the quartz glass tube due to the gap being too small or the shape being mismatched.

[0032] As a preferred embodiment, such as Figure 1 As shown, the support assembly 2 consists of two support guide rods 22, which are arranged parallel to each other in the horizontal direction and are simultaneously supported by a reinforcing beam 21 that is horizontally fixed to the inner wall of the frame 1. The fixing spacer 33 has through holes 31 at both ends and is fitted onto these two parallel support guide rods 22, forming a stable and reliable sliding guide system. The working principle of this utility model's hydrofluoric acid pickling rack for quartz glass tubes is as follows: When it is necessary to pickle quartz glass tubes, firstly, vertically insert each quartz glass tube into the upward-opening arc-shaped groove 34 on the upper edge of the fixing spacer 33 of the isolation component 3. The specific structure of the groove 34 supports and isolates each quartz glass tube, avoiding direct contact and collision damage between the tubes. Then, use nylon rope or other suitable binding material to pass through the binding groove 32 on the fixing spacer 33 to tightly bind and fix the isolation component 3 to the support guide rod 22 of the support component 2. This prevents the fixing spacer 33 from sliding or shaking along the support guide rod 22 in subsequent operations, ensuring that the quartz glass tubes remain in a fixed position during the pickling process.

[0033] After the quartz glass tube is installed and reinforced, the entire pickling rack filled with tubes is lifted smoothly by connecting the hooks of the gantry crane or other lifting equipment to the lifting lugs 4 fixed to the top of the frame 1. The rack is then slowly immersed in the prepared hydrofluoric acid solution, allowing the outer surface of the quartz glass tube to fully contact the acid solution for pickling. During the pickling process, the support legs 5 at the bottom of the frame 1 provide stable support when the pickling rack is not lifted, while the reinforcing beams 21 of the support components 2 effectively enhance the overall structural rigidity of the frame 1, making it less prone to deformation during lifting and pickling.

[0034] After the pickling reaches the predetermined time, the pickling rack is lifted out of the pickling solution pool using the lifting lug 4. At this time, the quartz glass tube installed in the slot 34 of the isolation component 3 has completed the surface treatment. Finally, subsequent processes such as rinsing and drying are carried out. The pickling rack realizes the convenient installation and spacing adjustment of the isolation component 3 through the sliding fitting structure of the support guide rod 22 and the through hole 31 of the fixing spacer 33. The slot 34 on the fixing spacer 33 ensures the undamaged fixed isolation of the quartz glass tube, while the reinforcing beam 21 ensures the stability of the entire load-bearing structure.

[0035] 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.
