Description

Technical Field

[0001] The utility model relates to the technical field of rare gas production equipment, in particular to a pipeline replacement structure of a rare gas membrane press. Background Art

[0002] In the production process of rare gases, membrane press is one of the important equipment. Through its unique membrane separation technology, membrane press can effectively separate and purify the rare gas components in the mixed gas and compress them to the required pressure to meet the requirements of subsequent processes.

[0003] The membrane press pipeline system needs to replace the gas in the pipeline before operation or after maintenance to ensure the purity of the gas and the requirements of the production process. Before operation, the pipeline may retain air, water vapor and other gas impurities left over from the previous production process. If these impurities are not removed, once they come into contact with and mix with the rare gas, the purity of the rare gas will be seriously damaged, making the produced rare gas unable to meet the strict purity definition in the relevant industry standards.

[0004] Traditional pipe replacement methods often have many drawbacks. When faced with pipes of different specifications, especially those with different diameters, securing the pipes during the replacement process becomes a major challenge. Conventional fixing devices are difficult to adapt to the different pipe diameters, and the pipes are prone to shaking during the fixing process, which makes pipe connection and alignment difficult.

[0005] Therefore, the utility model proposes a pipeline replacement structure for a rare gas membrane press. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a pipeline replacement structure for a rare gas membrane press.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a pipeline replacement structure of a rare gas membrane press, comprising:

[0008] The pipe fixing assembly consists of a sleeve clamp, a rubber sleeve, and two tightening rings arranged on both sides of the rubber sleeve. An arc-shaped top plate is arranged above the rubber sleeve to assist in tightening the sleeve clamp. A tightening screw is threadedly connected to the arc-shaped top plate to drive the sleeve clamp to tighten.

[0009] An adjustment assembly is used to assist the rotation of the pipe fixing assembly. The adjustment assembly includes a sleeve seat connecting seat and a rotating seat. The pipe fixing assembly is rotatably connected to the adjustment frame through the rotating seat for rotation. There are two adjustment frames in total, one of which is provided with a sliding rod, and the other is provided with a sliding groove for use with the sliding rod;

[0010] Wherein, the bottoms of the two adjustment frames are both provided with connecting seats;

[0011] The base is used to adjust the limit of the adjustment component. The base includes a sliding limit groove and an installation groove opened on the surface of the base. The adjustment frame is arranged in the corresponding sliding limit groove and installation groove through a connecting seat.

[0012] As a preferred embodiment, one of the adjustment frames is slidably connected to the sliding limit groove via a connecting seat.

[0013] The beneficial effect of adopting the above further scheme is: by slidingly connecting one of the adjustment frames between the connecting seat and the sliding limit groove, the distance between the two adjustment frames can be adjusted, thereby changing the connection position during pipeline replacement, and further under the action of the connecting seat, the sliding limit groove and the mounting groove, the adjustment frame is limited to ensure that the adjustment frame is always above the base during the sliding adjustment process.

[0014] As a preferred embodiment, mounting plates are provided on both sides of the base, and mounting holes are provided on both mounting plates.

[0015] The beneficial effect of adopting the above further scheme is: further under the action of the mounting plate, the mounting bolt is passed through the mounting hole and then threadedly connected to the mounting point to fix the base, thereby avoiding displacement of the base during use, which increases the difficulty of pipeline replacement work.

[0016] As a preferred embodiment, the two tightening rings are respectively embedded in the two ends of the rubber sleeve, and the two tightening rings are both retractable structures.

[0017] The beneficial effect of adopting the above further solution is: the pipeline is further limited under the action of the tightening ring. When the sleeve clamp is clamped inward, the tightening ring contracts and squeezes the pipeline, avoiding left and right displacement in the pipeline fixing assembly when the pipeline is replaced.

[0018] As a preferred embodiment, the arc-shaped top plate is embedded in the sleeve clamp and is located above the rubber sleeve.

[0019] The beneficial effect of adopting the above further solution is: under the action of the curved top plate, the tightening screw is installed, and under the action of the curved top plate, the top of the casing clamp can be assisted in expansion to avoid deformation and damage to the top of the casing clamp caused by excessive tightening of the tightening screw.

[0020] As a preferred embodiment, the sleeve seat connecting seat is arranged at the center of the bottom of the sleeve clamp, and the bottom of the sleeve seat connecting seat is rotatably connected to the top of the rotating seat.

[0021] The beneficial effect of adopting the above further scheme is that under the action of the rotating seat and the sleeve seat connecting seat, the pipe fixing assembly can be flipped on the adjustment assembly. The flippable structure can make the alignment work during the pipe replacement process more convenient and can be adjusted according to actual conditions.

[0022] As a preferred embodiment, the two adjustment frames are slidably connected via a slide rod and a slide groove, and the diameter of the rotating seat is adapted to the diameter of the slide rod.

[0023] The beneficial effect of adopting the above further scheme is: the two adjustment frames are limited by the sliding connection between the sliding rod and the sliding groove, so that the two adjustment frames can realize the sliding function while being limited by the sliding rod and the sliding groove, avoiding the two sliding rods being too far apart, resulting in misalignment and separation between the two adjustment frames.

[0024] Compared with the prior art, the advantages and positive effects of the present invention are:

[0025] In the present invention, during the process of pipe replacement, the pipes can first be connected and fixed by the adjustment component, and the two arc-shaped top plates are driven closer to each other by tightening the tightening screw. Under the action of the arc-shaped top plates, the sleeve clamp is clamped inward, and the tightening ring is tightened to squeeze and fix the pipe surface. After the fixation is completed, the distance between the two pipes is adjusted by the sliding adjustment frame. When the two pipes are fitted together, the two pipes can be rotated to a specified angle by the rotating seat and the sleeve seat connecting seat, so that the two pipes are aligned, so as to facilitate the subsequent connection and fixation work between the two pipes.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] like Figure 1-4As shown, the utility model provides a technical solution: a pipeline replacement structure of a rare gas membrane press, comprising: a pipeline fixing component 1, the pipeline fixing component 1 is composed of a sleeve clamp 11, a rubber sleeve 12 and two tightening rings 13 arranged on both sides of the rubber sleeve 12, an arc-shaped top plate 14 is arranged above the rubber sleeve 12 to assist the sleeve clamp 11 in tightening, and a tightening screw 15 is threadedly connected to the arc-shaped top plate 14 to drive the sleeve clamp 11 to tighten; an adjusting component 2, the adjusting component 2 is used to assist the pipeline fixing component 1 in rotating, and the adjusting component 2 includes a sleeve The pipe seat connecting seat 23 and the rotating seat 211, the pipe fixing component 1 is rotatably connected to the adjustment frame 21 through the rotating seat 21, and there are two adjustment frames 21, one of which is provided with a slide rod 22, and the other adjustment frame 21 is provided with a slide groove 221 used to cooperate with the slide rod 22; wherein, the bottom of the two adjustment frames 21 are provided with a connecting seat 212; the base 3, the base 3 is used to adjust the adjustment limit of the assembly 2, the base 3 includes a sliding limit groove 32 and a mounting groove 33 opened on the surface of the base 3, and the adjustment frame 21 is arranged in the corresponding sliding limit groove 32 and the installation groove 33 through the connecting seat 212, one of the adjustment frames 21 is slidably connected in the sliding limit groove 32 through the connecting seat 212, and the two tightening rings 13 are respectively embedded and installed in the two ends of the rubber sleeve 12. The two tightening rings 13 are both retractable structures, and the arc-shaped top plate 14 is arranged in an embedded manner above the sleeve clamp 11 on the rubber sleeve 12. During the process of pipe replacement, the pipe can first be connected and fixed by the adjustment component 2, and the two arc-shaped top plates 14 are driven to approach each other by tightening the tightening screw 15. Under the action of the arc-shaped top plate 14, the sleeve clamp 11 is clamped inward, and the tightening ring 13 is tightened to squeeze and fix the pipe surface. After the fixation is completed, the distance between the two pipes is adjusted by the sliding adjustment frame 21. When the two pipes are fitted together, the two pipes can be rotated to a specified angle by the rotating seat 211 and the sleeve seat connecting seat 23, so that the two pipes are aligned, so as to facilitate the subsequent connection and fixation work between the two pipes, thereby solving the technical problem of fixed alignment during pipe replacement.

[0036] The above solution also has the problem that the base 3 is easily displaced during use, such as Figure 2 As shown: In this solution, mounting plates 31 are provided on both sides of the base 3, and mounting holes 311 are opened on the two mounting plates 31.

The flippable structure can make the alignment work during the pipe replacement process more convenient and can be adjusted according to actual conditions. The two adjusting frames 21 are limited by the sliding connection between the sliding rod 22 and the sliding groove 221, so that the two adjusting frames 21 can realize the sliding function while being limited by the sliding rod 22 and the sliding groove 221 to avoid the two sliding rods 22 being too far apart, resulting in misalignment and separation between the two adjusting frames 21.

After the fixation is completed, the distance between the two pipes is adjusted by the sliding adjustment frame 21. When the two pipes are fitted together, the two pipes can be rotated to the specified angle by the rotating seat 211 and the sleeve seat connecting seat 23, so that the two pipes are aligned. After the alignment is completed, the two pipes can be connected.
