Description

Technical Field

[0001] The present application relates to the technical field of gas cylinder processing, and specifically to a gas cylinder processing device with a purification function. Background Art

[0002] A gas cylinder refers to a type of movable pressure vessel with a bottle-shaped main structure, generally filled with gas (which can be compressed gas, liquefied gas, dissolved adsorbed gas, etc.). Gas cylinders are widely used. Whether in the production field or in the field of life, gas cylinders are almost indispensable.

[0003] A gas cylinder baking system is a common gas cylinder processing device. The gas cylinder to be processed is placed in a baking oven, and the replacement gas pipeline in the baking oven is connected to the gas cylinder. The baking oven heats the gas cylinder to convert the moisture inside the gas cylinder into water vapor. The moisture is then pumped out with a vacuum pump, and the replacement gas is then added. The gas cylinder is baked again to vacuum and replace the water. After several cycles, the gas cylinder can be guaranteed to be free of moisture. For example, Chinese Patent Publication No. CN217868989U discloses a gas cylinder body heat treatment frame. The heat treatment frame assembly is composed of several stacked heat treatment frames. Connecting brackets are provided between the four columns of the stacked heat treatment frames to fix them together as an integral assembly. During heat treatment, they can be hoisted synchronously. The bottom of the heat treatment frame cavity is evenly laid with cross-shaped limit rods to form several storage chambers. The bottom of the upright limit plate and the cross-shaped limit rods define the position of the upright gas cylinders, which can prevent collisions between the upright gas cylinders. The storage chamber allows straight-through hollowing or partial hollowing, which is conducive to accommodating gas cylinders of different heights and improving heat treatment efficiency.

[0004] The core processing method of this patent is the same as the common processing method, both of which use a baking oven for processing, and during the processing process, replacement gas needs to be injected into it. In the existing technology, the quality of the replacement gas fluctuates to a certain extent. After the replacement gas is input, if the quality is unstable, it will cause uneven quality of gas cylinder processing, thereby affecting the stability of the overall quality. In this regard, this application provides a gas cylinder processing device with purification function to solve the above problem. Utility Model Content

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] See also Figures 1 to 3 The present application provides a technical solution: a gas cylinder processing device with a purification function, comprising a main pipeline 1, a purification component 200 for purifying replacement gas is installed at one end of the main pipeline 1, a processing component 300 for processing the gas cylinder is installed at the other end of the main pipeline 1, and a replacement gas switching valve 4 is fixedly installed on the outside of the main pipeline 1; through the coordinated use of the main pipeline 1, the purification component 200 and the processing component 300, the stability of the gas cylinder processing can be improved, and it can also be selected according to the actual needs of the user whether the replacement gas needs to be processed, thereby improving the adaptability of the entire processing flow, enabling it to meet the gas cylinder processing work with different requirements, thereby effectively improving the practicality of the gas cylinder processing device.

[0031] In this embodiment, the purification component 200 is a structure for purifying the replacement gas.

[0032] like Figure 1 and Figure 2As shown, the purification assembly 200 includes two replacement gas purifiers 201, two input pipes 202, two purifier inlet valves 203, a first three-way pipe 204, two output pipes 205, two purifier outlet filters 206, two purifier outlet valves 207, a second three-way pipe 208 and a connecting pipe 209; the input end of the replacement gas purifier 201 is fixedly connected to the end of the corresponding input pipe 202, the other end of the two input pipes 202 is fixedly connected to the two bottom ends of the first three-way pipe 204 respectively, and the purifier inlet valve 203 is fixedly installed on the corresponding input pipe 2 02, the top of the first three-way pipe 204 is fixedly connected to the bottom of the main pipeline 1, the output pipe 205 is fixed to the output end of the corresponding replacement gas purifier 201, the purifier outlet filter 206 is fixedly installed on the outside of the corresponding output pipe 205, and the purifier outlet valve 207 is fixedly installed on the outside of the corresponding output pipe 205. The bottom ends of the two output pipes 205 are respectively fixedly connected to the two top ends of the second three-way pipe 208, the bottom end of the second three-way pipe 208 is fixedly connected to the bottom end of the connecting pipe 209, and the top of the connecting pipe 209 is fixedly connected to the bottom of the main pipeline 1.

[0033] It should be noted that the purifier outlet filter 206 is located on the side of the output pipe 205 close to the replacement gas purifier 201, and the purifier outlet valve 207 is located on the side of the output pipe 205 away from the replacement gas purifier 201, so that the replacement gas discharged from the replacement gas purifier 201 can first be filtered by the purifier outlet filter 206 and then input into the interior of the second three-way pipe 208 through the purifier outlet valve 207. The purifier outlet filter 206 can be a conventional gas dehumidification adsorption filter, such as an activated carbon filter, etc., and both are existing publicly available technologies, so no further details are given.

[0034] In addition, the displacement gas purifier 201 is an existing gas purifier. The working principle of the gas purifier mainly includes adsorption, desorption, regeneration and other processes. The adsorbent can selectively adsorb impurities in the gas, thereby achieving the purpose of purifying the gas. The membrane separation purifier uses the different permeabilities of membrane materials to different gases to remove impurities. The chemical reaction purifier converts impurities into other substances through chemical reactions, thereby achieving the purpose of purification. The use of catalysts and the reaction mechanism are also important parts of the chemical reaction purifier. As long as it is a gas purifier that can purify the displacement gas, it can be used, and they are all existing publicly available gas purifiers, so there is no need to elaborate on them.

[0035] In this embodiment, the processing assembly 300 is a structure for performing exhaust and drying processing on the gas cylinder body 302 .

[0036] like Figure 1 and Figure 3As shown, the processing component 300 includes a baking oven body 301, several gas cylinder bodies 302, a fixed pipe 303, a vacuum pump 304, a vent pipe 305, an analysis pipe 306 and two control valves 307; the gas cylinder body 302 is detachably connected to the inner side of the baking oven body 301, the top of the fixed pipe 303 is fixedly connected to the bottom of the main pipe 1, the bottom end of the fixed pipe 303 passes through the top of the baking oven body 301 and is detachably connected to the input ends of the several gas cylinder bodies 302, the vacuum pump 304 is fixedly installed at one end of the main pipe 1 away from the replacement gas purifier 201, the left ends of the vent pipe 305 and the analysis pipe 306 are both fixedly connected to the outside of the main pipe 1, and the two control valves 307 are fixedly installed on the outside of the vent pipe 305 and the analysis pipe 306 respectively.

[0037] It should be noted that multiple extension pipes are fixed to the bottom end of the fixed pipe 303, and the extension pipe shell is detachably connected to the input end of the gas cylinder body 302, so that the gas cylinder body 302 can achieve the function of exhausting or injecting gas through the extension pipe and the fixed pipe 303. Among them, the baking oven body 301 is a box structure that can be heated and dried in the existing technology, which can be achieved through the cooperation of electric heating pipes and fans, which is an existing public technology.

[0038] In addition, the vacuum pump 304 is located at the output end of the main pipeline 1, and the replacement gas purifier 201 and the baking oven body 301 are both located on the side close to the input end of the main pipeline 1, so that the replacement gas input by the main pipeline 1 can first enter the interior of the replacement gas purifier 201 or the baking oven body 301, and the vacuum pump 304 can exhaust the entire main pipeline 1. The venting pipe 305 and the analysis pipe 306 are both located on the side close to the vacuum pump 304, so that by opening the control valve 307, the interior of the main pipeline 1 can be vented through the venting pipe 305, or the replacement gas inside the main pipeline 1 can be sampled, tested and analyzed through the analysis pipe 306, which is convenient for accurate grasp.

[0039] At the same time, the replacement gas switching valve 4 is located between the first three-way pipe 204 and the connecting pipe 209 on opposite sides, and the connecting pipe 209 is located between the replacement gas purifier 201 and the baking oven body 301 on opposite sides, so that the gas inside the main pipeline 1 can enter the interior of the first three-way pipe 204 when the replacement gas switching valve 4 is closed, and when the replacement gas switching valve 4 is opened, it can be directly input into the gas cylinder body 302 inside the baking oven body 301 through the main pipeline 1 for gas replacement.

[0040] The working principle of the above embodiment is:

[0041] During use, the replacement gas switching valve 4, the purifier inlet valve 203, and the purifier outlet valve 207 are opened or closed to control whether the replacement gas needs to be purified by the replacement gas purifier 201. When the gas cylinder body 302 with higher processing requirements needs to be processed, the replacement gas switching valve 4 is closed, the purifier inlet valve 203 and the corresponding purifier outlet valve 207 are opened, so that the two replacement gas purifiers 201 can be switched for use, so that the replacement gas can enter the interior of the corresponding replacement gas purifier 201 through the first three-way pipe 204 and the input pipe 202 for processing, thereby further reducing the water content of the replacement gas. The treated replacement gas passes through the corresponding purifier outlet filter 206 and the second three-way pipe 20 8 is input into the interior of the connecting pipe 209, and then enters the interior of the gas cylinder body 302 in the baking oven body 301 through the main pipe 1 and the fixed pipe 303. Before this, it is necessary to start the baking oven body 301 and the vacuum pump 304 first, so that the gas cylinder body 302 is heated by the baking oven body 301 and evacuated by the vacuum pump 304, and then the treated replacement gas is input. After input, it is baked and vacuumed again by the baking oven body 301 and the vacuum pump 304. After several cycles, it can be ensured that there is no moisture in the gas cylinder body 302. Even if there is residual gas, it is the high-purity gas input after the replacement is completed, thereby achieving the purpose of improving the treatment quality and stability of the gas cylinder body 302.

[0042] Compared with the existing technology, the gas cylinder processing device with purification function can improve the stability of gas cylinder processing through the coordinated use of the main pipeline 1, the purification component 200 and the processing component 300, and can also choose whether to process the replacement gas according to the actual needs of the user, thereby improving the adaptability of the entire processing flow, enabling it to meet the gas cylinder processing work with different requirements, thereby effectively improving the practicality of the gas cylinder processing device, and solving the problem that the existing gas cylinder processing device is easily affected by the replacement gas during the actual processing process, resulting in unstable processing quality.

[0043] The electrical components appearing in this article are all electrically connected to the main controller and the power supply. The provision of power supply is common knowledge in this field. The main controller can be a conventional known device that controls a computer, etc., and can be implemented through simple programming by technicians in this field. These are all existing publicly available power connection technologies and will not be described in detail in this article.
