Description

Technical Field

[0001] This utility model belongs to the field of gas cylinder technology, and in particular relates to a steel cylinder processing system for filling ultra-high purity gas. Background Technology

[0002] Process gases are generally stored in steel cylinders. New steel cylinders or steel cylinders that have been used for a long time often contain certain impurities on their inner walls. If the gas is filled directly, especially when filling high-purity gas, the purity of the gas will be seriously affected. The steel cylinder needs to be pre-treated before filling to ensure that the inside of the steel cylinder is pure and free of impurities. This is done by replacing the gas source (nitrogen) and vacuuming.

[0003] In conventional gas cylinder handling devices, the gas storage pipelines are usually arranged in a fixed manner, making it difficult to change the pipeline layout. Because the pipeline path is fixed and cannot be adjusted, this limits the applicability of the device in different scenarios. When the pipeline system malfunctions or requires maintenance, the fixed pipeline layout may increase the difficulty of repair, and maintenance personnel may need to spend more time and effort to locate the problem and repair it. Therefore, we propose a gas cylinder handling system for filling ultra-high purity gas. Utility Model Content

[0004] The purpose of this invention is to provide a cylinder handling system for filling ultra-high purity gas. By setting an adjustment component, the mobility of the support block allows the installation position of the pipeline to be no longer fixed, but can be flexibly adjusted according to actual needs. This can easily optimize the pipeline layout and solve the problem that the existing pipeline path is fixed and cannot be adjusted, which limits the applicability of the device in different scenarios. When the pipeline system malfunctions or needs maintenance, the fixed pipeline layout may increase the difficulty of maintenance.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a cylinder handling system for filling ultra-high purity gas, including a pipe, a connecting pipe at the bottom end of the pipe, a support frame at the back of the pipe, and a plurality of support blocks slidably connected to the inner wall of the support frame, the plurality of support blocks having the same internal structure.

[0007] The support frame has a limiting hole at its bottom, and the support block has a placement groove inside. An adjustment assembly is installed inside the placement groove. The adjustment assembly includes a pull rod that penetrates the side wall of the support block. A pull ring is attached to the end of the pull rod away from the support block. A limiting block is located at the bottom of the support block, and the inner wall of the limiting block is fixedly connected to the outer surface of the pull rod. A spring is installed on the inner wall of the placement groove and is fitted onto the surface of the pull rod. A baffle is fixedly connected to the top of the pull rod, and the bottom of the baffle is fixedly connected to the end of the spring away from the limiting block. When the pull rod moves, it causes the limiting block to move towards the inner wall of the limiting hole, thereby fixing the support block inside the support frame and preventing it from moving. The mobility of the support block allows the installation position of the pipeline to be adjusted flexibly according to actual needs, facilitating optimization of the pipeline layout.

[0008] Furthermore, a fixing component is provided on the side of the support block near the pipe. The fixing component includes a buckle rotatably connected to the surface of the support block. A push block is fixedly connected to the end of the buckle away from the support block. The side of the push block away from the buckle is arc-shaped. The surface of the buckle in contact with the pipe is elastic, similar to rubber material, which not only prevents wear on the surface of the pipe, but also increases the clamping and fixing effect on the pipe.

[0009] Furthermore, a fixing block is fixedly connected to the right side of the support block, and a sliding rod is fixedly connected to the inner wall of the fixing block. The left side of the sliding rod is fixedly connected to the outer surface of the support block. A limit pin is provided on the side of the push block near the sliding rod. The inner wall of the limit pin is slidably connected to the outer surface of the sliding rod. A spring is sleeved on the outer surface of the sliding rod. Since the surface of the push block near the limit pin is arc-shaped, the push block will push the limit pin to move on the surface of the sliding rod.

[0010] Furthermore, the second spring is disposed between the limiting pin and the support block. The end of the second spring near the support block is fixedly connected to the outer surface of the support block, and the end of the second spring away from the support block is fixedly connected to the side wall of the limiting pin. The elastic force generated by the second spring pulls the limiting pin to reset, fixing the push block, thereby fixing the pipe to the surface of the support block, realizing the rapid positioning and fixing of the pipe. Compared with the clamp fixing method, no additional bolt tightening and adjustment steps are required, which greatly simplifies the installation process.

[0011] Furthermore, the end of the pipe is provided with a cap. When there is an unused pipe outlet connected to the inner wall of the cap and the outer surface of the pipe by a thread, the cap is put on the end of the pipe and rotated clockwise.

[0012] Furthermore, the end cap has a protrusion inside, and a rubber gasket is fixedly connected to the outer surface of the protrusion. As the end cap rotates, the rubber gasket contacts the inner wall of the pipe, sealing the end of the pipe.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, through the setting of an adjustment component, specifically, firstly, the pull ring moves the pull rod downwards. As the pull ring moves downwards, it compresses the spring through the baffle. The spring, under compression, generates elastic force, which, while the pull rod slides downwards, moves the limiting block away from the inner wall of the limiting hole. At this time, the movable support block can slide freely on the inner wall of the support frame. When it reaches the path where the pipeline needs to be installed, the pull ring is released. As the pull rod moves, it moves the limiting block towards the inner wall of the limiting hole, thereby fixing the support block inside the support frame and preventing it from moving. The mobility of the support block means that the installation position of the pipeline is no longer fixed, but can be flexibly adjusted according to actual needs, which can easily optimize the pipeline layout.

[0015] 2. This utility model uses a fixing component to attach the pipe to the surface of the support block. The rotating elbow wraps around the pipe. When the push block rotates to the inner wall of the limit pin, the elastic force generated by the second spring pulls the limit pin back to its original position, fixing the push block and thus fixing the pipe to the surface of the support block. This achieves quick positioning and fixing of the pipe. Compared with the clamp fixing method, no additional bolt tightening and adjustment steps are required, which greatly simplifies the installation process. When it is necessary to remove the pipe, simply move the limit pin away from the push block, and the pipe can be removed by drilling the elbow. The disassembly and replacement of the pipe becomes much simpler.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] 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 scope of protection of the present utility model.

[0027] Please see Figure 1-6 As shown, this utility model is a cylinder handling system for filling ultra-high purity gas, including a pipe 1, a connecting pipe 102 at the bottom end of the pipe 1, a support frame 101 on the back of the pipe 1, and a plurality of support blocks 105 slidably connected to the inner wall of the support frame 101, the internal structure of the plurality of support blocks 105 being the same.

[0028] The support frame 101 has a limiting hole 104 at its bottom. The support block 105 has a placement groove inside, and an adjustment component 2 is installed inside the placement groove. The adjustment component 2 includes a pull rod 201 that passes through the side wall of the support block 105. A pull ring is provided at the end of the pull rod 201 away from the support block 105. A limiting block 202 is provided at the bottom of the support block 105, and the inner wall of the limiting block 202 is fixedly connected to the outer surface of the pull rod 201. A spring 204 is provided on the inner wall of the placement groove and is sleeved on the surface of the pull rod 201. A baffle 203 is fixedly connected to the top of the pull rod 201, and the bottom of the baffle 203 is fixedly connected to the end of the spring 204 away from the limiting block 202. Specifically, by setting the adjustment component 2, the pull ring is first used to adjust the... The pull rod 201 moves downward, and the pull ring moves downward while pressing the spring 204 through the baffle 203. The spring 204 generates elastic force under compression. As the pull rod 201 slides downward, it moves the limiting block 202 away from the inner wall of the limiting hole 104. At this time, the support block 105 can slide freely on the inner wall of the support frame 101. When it moves to the path where the pipeline needs to be installed, the pull ring is released. As the pull rod 201 moves, it moves the limiting block 202 towards the inner wall of the limiting hole 104, thereby fixing the support block 105 inside the support frame 101 and preventing it from moving. The mobility of the support block 105 makes the installation position of the pipeline no longer fixed, but can be flexibly adjusted according to actual needs, which can easily optimize the pipeline layout.

[0029] A fixing component 3 is provided on the side of the support block 105 near the pipe 1. The fixing component 3 includes a bend 301 rotatably connected to the surface of the support block 105. A push block 302 is fixedly connected to the end of the bend 301 away from the support block 105. The side of the push block 302 away from the bend 301 is curved.

[0030] A fixing block 304 is fixedly connected to the right side of the support block 105, and a slide rod 305 is fixedly connected to the inner wall of the fixing block 304. The left side of the slide rod 305 is fixedly connected to the outer surface of the support block 105.

[0031] A limit pin 303 is provided on the side of the push block 302 near the slide rod 305. The inner wall of the limit pin 303 is slidably connected to the outer surface of the slide rod 305. A spring 306 is sleeved on the outer surface of the slide rod 305.

[0032] Spring 306 is positioned between the limiting pin 303 and the support block 105. The end of spring 306 closest to the support block 105 is fixedly connected to the outer surface of the support block 105, and the end of spring 306 furthest from the support block 105 is fixedly connected to the side wall of the limiting pin 303. By setting the fixing component 3, specifically, the pipe 1 is attached to the surface of the support block 105, and the elbow 301 is rotated to wrap around the pipe 1. When the push block 302 rotates to the inner wall of the limiting pin 303, the elastic force generated by spring 306 pulls the limiting pin 303 back to its original position, fixing the push block 302, thereby fixing the pipe 1 to the surface of the support block 105. This achieves quick positioning and fixing of the pipe 1. Compared with the clamp fixing method, no additional bolt tightening and adjustment steps are required, greatly simplifying the installation process. When it is necessary to remove the pipe 1, simply move the limiting pin 303 away from the push block 302, and the elbow 301 can be drilled to remove the pipe 1. The disassembly and replacement of the pipe 1 becomes much simpler.

[0033] The end of the pipe 1 is provided with a cap 103, and the inner wall of the cap 103 is threadedly connected to the outer surface of the pipe 1.

[0034] The end cap 103 has a protrusion inside, and a rubber gasket 401 is fixedly connected to the outer surface of the protrusion.

[0035] One specific application of this embodiment is as follows: Before filling ultra-high purity gas cylinders, the cylinders need to be treated to ensure that the inside of the cylinders is pure and free of impurities. Therefore, equipment is needed to clean the cylinders. The support frame 101 is fixed to the wall with bolts. According to the pre-designed pipeline, the movable support block 105 slides on the inner wall of the support frame 101. During the movement of the support block 105, the pull ring first drives the pull rod 201 to move downward. At the same time as the pull ring moves downward, the baffle 203 compresses the spring 204. The spring 204 generates elastic force under compression. At the same time as the pull rod 201 slides downward, it drives the limiting block 202 away from the inner limit hole 104. The support block 105 can slide freely on the inner wall of the support frame 101. When it moves to the path where the pipe needs to be installed, the pull ring is released, and the elastic force generated by the spring 204 pushes the baffle 203 to move upward, thereby driving the pull rod 201 to move upward. As the pull rod 201 moves, it drives the limiting block 202 to move towards the inner wall of the limiting hole 104, thereby fixing the support block 105 inside the support frame 101 and preventing it from moving. The mobility of the support block 105 makes the installation position of the pipe no longer fixed, but can be flexibly adjusted according to actual needs. This can easily optimize the pipe layout, reduce unnecessary bends and joints, and thus reduce the risk of gas leakage.

[0036] After the support block 105 is fixed, the pipe 1 is installed according to the position of the support block 105. The pipe 1 is placed against the surface of the support block 105, and the elbow 301 is rotated to wrap around the pipe 1. When the push block 302 at the end of the elbow 301 contacts the limiting pin 303, since the surface of the push block 302 near the limiting pin 303 is arc-shaped, the push block 302 will push the limiting pin 303 to move on the surface of the slide bar 305. As the limiting pin 303 moves away from the support block 105, the spring 2 306 is stretched to generate elastic force. When block 302 rotates to the inner wall of limit pin 303, the elastic force generated by spring 2 306 pulls limit pin 303 to reset, fixing push block 302, thereby fixing pipe 1 to the surface of support block 105, realizing quick positioning and fixing of pipe 1. Compared with clamp fixing method, no additional bolt tightening and adjustment steps are required, which greatly simplifies the installation process. When it is necessary to remove pipe 1, simply move limit pin 303 away from push block 302, and you can drill a hole and bend buckle 301 to remove pipe 1. The disassembly and replacement of pipe 1 becomes simpler.

[0037] Gas inside pipe 1 is introduced into the cylinder through connecting pipe 102 to clean the inside of the cylinder. The equipment has multiple gas outlets for pipe 1. When there is an unused gas outlet for pipe 1, the end cap 103 is put on the end of pipe 1 and rotated clockwise. The inner wall of the end cap 103 is provided with a rubber gasket 401. As the end cap 103 rotates, the rubber gasket 401 contacts the inner wall of pipe 1, sealing the end of pipe 1.
