Description

Technical Field

[0001] This utility model relates to the field of liquid argon purification shaft technology, and in particular to a high-purity liquid argon purification device. Background Technology

[0002] The high-purity liquid argon purification device includes a distillation column, a cryogenic condenser, an adsorption column, a vacuum pump, a compressor, and a filter. First, the preparation of liquid argon begins by passing gaseous argon through a filter and adsorbent to remove impurities such as suspended solids, oxygen, and moisture. After gas purification, the argon is condensed into a liquid phase. The liquid argon is then separated in the distillation column, and the argon is purified step by step according to the boiling point order of different impurities to improve its purity. The adsorption column is then used to further remove other gaseous, liquid, or solid impurities.

[0003] When removing suspended solids, oxygen, moisture, and other impurities through filters and adsorbents, the filters composed of filter components and adsorption structures can become saturated, requiring regular cleaning. However, cleaning results in long downtime for the equipment, and the disassembly and assembly of the processing components are cumbersome and time-consuming. To address these issues, we propose a high-purity liquid argon purification device. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a high-purity liquid argon purification device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-purity liquid argon purification device, comprising a fixed box, a top plate, an upper box body, a lower box body, a middle plate, and a bottom plate. The upper box body is fitted into the upper end of the fixed box, and the lower box body is fitted into the lower end of the fixed box. A middle plate is provided inside the fixed box. A filter screen, porous ceramic, grid plate one, grid plate two, and grid plate three are installed through the middle plate. The filter screen, porous ceramic, grid plate one, grid plate two, and grid plate three are respectively provided with a top plate and a bottom plate at their upper and lower ends. A processing chamber one is provided between the top plate and the middle plate, and a processing chamber two is provided between the middle plate and the bottom plate. An upper docking frame is provided inside the upper box body, and a lower docking frame is provided inside the lower box body.

[0006] When using the high-purity liquid argon purification device in this solution, argon gas is introduced into the fixed box through the input pipe. When passing through the filter, solid particles suspended in the gaseous argon are intercepted. The argon gas passing through the filter passes through porous ceramic to remove tiny solid particles in the gas flow. The argon gas passing through the porous ceramic passes through grid plate one and enters the space between grid plate one and grid plate two. The activated carbon stored in this space adsorbs volatile organic compounds and some oxygen in the gaseous argon. The argon gas with adsorbed oxygen and volatile organic compounds passes through grid plate two and enters the space between grid plate two and grid plate three. In this space, the desiccant stored in the space adsorbs moisture and water vapor in the gaseous argon. At the same time, a molecular sieve can be set in this space to remove neon and oxygen.

[0007] Preferably, a sealing gasket is provided at the joint between the upper housing and the fixed housing, and connecting plates are provided at both the front and rear ends of the fixed housing. A hydraulic rod is provided at both the front and rear ends of the fixed housing, with its telescopic end connected to the lower end of the connecting plate. The sealing gasket enhances the sealing at the joint between the upper housing and the fixed housing, and the hydraulic rod drives the connecting plate to move longitudinally, thus opening the upper part of the mounting box.

[0008] Preferably, a second sealing gasket is provided at the joint between the lower housing and the fixed housing, and a first connecting plate is provided at both the front and rear ends of the fixed housing. A first hydraulic rod with a telescopic end connected to the upper end of the first connecting plate is provided at both the front and rear ends of the fixed housing. The sealing gasket enhances the sealing performance at the joint between the lower housing and the fixed housing, and the first hydraulic rod drives the first connecting plate to move longitudinally, thus opening the lower end of the mounting box.

[0009] Preferably, the inner walls of both the front and rear sides of the fixed box are provided with side plates, and the front and rear ends of the fixed box are provided with hydraulic rods three that are slidably installed inside the fixed box and connected to the side plates. The hydraulic rods drive the side plates to move and fit against the front and rear ends of the filter screen, porous ceramic, grid plate one, grid plate two, and grid plate three.

[0010] Preferably, the inner walls of both the upper and lower docking frames are provided with sealing sleeves, and the top plate, middle plate, and bottom plate are all slidably installed with the sealing sleeves. When the top plate, middle plate, and bottom plate slide inside the upper and lower docking frames, the sealing sleeves improve the sealing performance at the contact points with the upper and lower docking frames.

[0011] Preferably, the fixed box has an input pipe and an output pipe connected to both ends, and both the input and output pipes are fitted with flanges on their outer walls. Mounting brackets are provided at both the front and rear ends of the fixed box. The input pipe is connected to a pipeline for argon gas, and the output pipe is connected to a pipeline for filtered argon gas.

[0012] Preferably, the inner wall of the fixed box is provided with a sealing sleeve two, and the side plate is slidably installed on the inner wall of the sealing sleeve two. Each side plate has a sealing gasket three at one opposite end. When the side plate moves inside the fixed box, it fits against the inner wall of the fixed box through the sealing gasket two, and the opposite ends of the side plate are effectively fitted with the filter screen, porous ceramic, grid plate one, grid plate two, and grid plate three at the front and rear ends through the sealing gasket three.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses filters inside the fixed box, upper box and lower box to block solid particles suspended in gaseous argon, porous ceramic to remove tiny solid particles in the gas flow, activated carbon stored in the space between partition one and partition two to adsorb volatile organic compounds and some oxygen in gaseous argon, and desiccant stored in partition two and partition three to adsorb moisture and water vapor in gaseous argon, thereby achieving the filtration treatment of gaseous argon;

[0015] Meanwhile, the filter assembly and adsorption structure, composed of porous ceramics, grid plate one, grid plate two, and grid plate three, are snapped together with the main structure fixing box, upper box, and lower box, and can move longitudinally. The filter assembly and adsorption structure are divided into multiple sections. When cleaning or regenerating the saturated filter assembly and adsorption structure, the unused filter assembly and adsorption structure sections can be directly switched, thereby shortening the downtime for cleaning or regenerating the filter assembly and adsorption structure in the argon gas treatment of high-purity liquid argon process, avoiding the cumbersome disassembly and assembly of the equipment, and making the cleaning and regeneration of the filter assembly and adsorption structure convenient.

[0022] 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.

[0023] like Figures 1-5 As shown, the present invention proposes a high-purity liquid argon purification device, comprising a fixed box 1, a top plate 2, an upper box body 3, a lower box body 5, a middle plate 21, and a bottom plate 22. The upper box body 3 is fitted into the upper end of the fixed box 1, and the lower box body 5 is fitted into the lower end of the fixed box 1. The middle plate 21 is provided inside the fixed box 1. A filter screen 7, a porous ceramic 8, a grid plate one 9, a grid plate two 10, and a grid plate three 11 are installed through the middle plate 21. The top plate 2 and the bottom plate 22 are respectively provided at the upper and lower ends of the filter screen 7, the porous ceramic 8, the grid plate one 9, the grid plate two 10, and the grid plate three 11. A processing chamber one 23 is provided between the top plate 2 and the middle plate 21, and a processing chamber two 24 is provided between the middle plate 21 and the bottom plate 22. An upper docking frame 18 is provided inside the upper box body 3, and a lower docking frame 19 is provided inside the lower box body 5.

[0024] The front and rear inner walls of the fixed box 1 are provided with side plates 20, and the front and rear ends of the fixed box 1 are provided with hydraulic rods 17 that are slidably installed inside the fixed box 1 and connected to the side plates 20.

[0025] The inner walls of the upper docking frame 18 and the lower docking frame 19 are each provided with a sealing sleeve 1, and the top plate 2, the middle plate 21 and the bottom plate 22 are all slidably installed with the sealing sleeve 1;

[0026] The fixed box 1 has an input pipe 4 and an output pipe 12 connected to its two ends respectively. The outer walls of the input pipe 4 and the output pipe 12 are fitted with flanges. The fixed box 1 has mounting brackets 6 at both the front and rear ends.

[0027] The inner wall of the fixed box 1 is provided with a sealing sleeve 2, and the side plate 20 is slidably installed on the inner wall of the sealing sleeve 2. Each side plate 20 is provided with a sealing gasket 3 at one opposite end.

[0028] Based on the implementation steps of Example 1: It is worth noting that the top plate 2 or bottom plate 22 needs to be installed with a longitudinal lifting and moving structure. A telescopic rod connected to the top plate 2 or bottom plate 22 and moving longitudinally can be used as a hydraulic or pneumatic power source to ensure that the filter assembly and adsorption structure composed of filter screen 7, porous ceramic 8, grid plate one 9, grid plate two 10 and grid plate three 11 are effectively and stably fixed in the fixed box 1. When the filter assembly and adsorption structure need to be cleaned and regenerated, the filter assembly and adsorption structure are lifted, the processing chamber one 23 is moved out of the fixed box 1, and the processing chamber two 24 enters the fixed box 1. The unused filter assembly and adsorption structure are directly adjusted into the fixed box 1, realizing the rapid maintenance and use of the filter assembly and adsorption structure, shortening the maintenance time of the filter assembly and adsorption structure, and avoiding the need for technicians to disassemble and assemble the filter assembly and adsorption structure that constitute the filter in the high-purity liquid argon purification device. The filter assembly and adsorption structure are easy to use, and the filter assembly and adsorption structure inside the filter chamber one are cleaned and regenerated.

[0030] A sealing gasket is provided at the joint between the lower box 5 and the fixed box 1. A connecting plate 13 is provided at both the front and rear ends of the fixed box 1. A hydraulic rod 14 with a telescopic end connected to the upper end of the connecting plate 13 is provided at both the front and rear ends of the fixed box 1.

[0031] In this embodiment, after the second treatment chamber 24 enters the fixed box 1, the hydraulic rod 215 drives the connecting plate 216 to rise, causing the upper box 3 to disengage from the fixed box 1 and enter the fixed box 1. The filter screen 7, porous ceramic 8, grid plate 1 9, grid plate 2 10, and grid plate 3 11 in the second treatment chamber 24 are open at the top, and the necessary activated carbon, desiccant, etc. are added inside. Similarly, when the filter components and adsorption structure inside the second treatment chamber 24 need to be cleaned and regenerated, the filter components and adsorption structure descend, and nine-tenths of the first filter chamber enters the fixed box 1. Activated carbon, desiccant, etc. are added through the gap between the top plate 2 and the upper connecting frame 18, and then the box is completely closed. The hydraulic rod 14 drives the connecting plate 13 to lower the lower box 5, providing convenience for the maintenance of the filter components and adsorption structure.
