[0005] During the helium purification operation, as the purification continues, the water-absorbing raw materials in the water removal equipment will gradually become saturated. When the water-absorbing raw materials are replaced, the pipeline between the water removal equipment and the helium purification box needs to be closed, which reduces the operating efficiency of the helium purification and makes it impossible to achieve continuous helium purification. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a helium purification device, such as: by setting up multiple water absorption devices, the helium purification operation can be continuously performed when part of the water absorption raw materials are replaced, thereby improving the efficiency of the helium purification operation.

[0010] Furthermore, a carrying rod is fixedly connected to the inner wall of the filter material box at one end close to the box cover, and a side of the carrying rod away from the filter material box abuts against the box cover.

[0011] Furthermore, two symmetrically arranged mounting grooves are provided on both sides of the filter material box, and symmetrically arranged mounting bars are fixedly connected to both sides of the filter box, and the two mounting bars are slidably connected to the two mounting grooves respectively.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1 - Figure 5 A helium purification device comprises a purification box 1, a collection box 2 and a horizontal plate 3 installed between the purification box 1 and the collection box 2, the upper surface of the horizontal plate 3 is connected to two symmetrically arranged filter boxes 4, both sides of the two filter boxes 4 are fixedly connected and communicated with gas pipes 5, four gas pipes 5 are respectively communicated with the purification box 1 and the collection box 2, the outer walls of the four gas pipes 5 are fixedly connected and communicated with valves 6, the tops of the adjacent sides of the two filter boxes 4 are hinged with box covers 7, the other sides of the two box covers 7 are connected with locking pieces 13, the other sides of the two locking pieces 13 are respectively connected to the two filter boxes 4, and a sealing gasket is connected between the box cover 7 and the filter box 4.

[0024] like Figure 1 - Figure 5 As shown, the helium purification device in the utility model is similar in structure to the existing helium purification device, such as a helium concentration and purification device disclosed in the patent with publication number CN216273117U. The main improvement of the utility model is that the user can maintain the normal filtration of helium when replacing the filter material, thereby further improving the filtration efficiency of helium. Figures 1 to 5As shown, when the helium purification equipment in the utility model is in use, the two filter boxes 4 are used to filter and purify the helium. When the filter material in the filter box 4 needs to be replaced, the valves 6 on the gas pipes 5 on both sides of the current filter box 4 can be closed, and then the box cover 7 can be opened to replace the filter material inside the filter box 4. At the same time, the other filter box 4 can continue to filter the helium, ensuring the continuity of the helium filtering operation, further improving the filtering efficiency of the helium, and at the same time avoiding the helium in the purification box 1 from being unable to be output through the gas pipe 5, causing the internal air pressure of the purification box 1 to increase, thereby improving the safety of the purification process, and through the arrangement and installation of the two filter boxes 4, the filtering efficiency of the helium can be greatly improved.

[0025] like Figure 1 - Figure 3 As shown, the two gas pipes 5 on the same side are fixedly connected and communicated with a three-way joint 8, the other end of the three-way joint 8 is fixedly connected and communicated with a connecting pipe 9, and the other end of the connecting pipe 9 is fixedly connected and communicated with the adjacent purification box 1 or the collection box 2. The two gas pipes 5 on the same side are connected to the connecting pipe 9 through the three-way joint 8, and the filter box 4 is connected to the purification box 1 and the collection box 2 through the two connecting pipes 9, which can reduce the setting of pipelines as much as possible and further reduce the waste of pipes.

[0026] like Figure 4 and Figure 5 As shown, the filter box 4 is fixedly connected to the horizontal plate 3, and the inner wall of the filter box 4 is slidably connected with a filter material box 10. A plurality of ventilation holes 101 are penetrated on both sides of the filter material box 10 close to the purification box 1 and the collection box 2. The bottom outer wall of the filter material box 10 abuts against the bottom inner wall of the filter box 4, and the top of the filter material box 10 abuts against the box cover 7. The filter box 4 is installed and fixed on the horizontal plate 3, so as to avoid shaking at the connection between the filter box 4 and the gas pipe 5, and improve the connection firmness of the pipeline. At the same time, a filter material box 10 is arranged in the filter box 4, and the materials required for filtering can be placed in the filter material box 10, so as to facilitate the replacement of the filter material through the filter material box 10. When the helium in the purification box 1 enters the filter box 4 through the connecting pipe 9 and the gas pipe 5, the helium enters the filter material box 10 through the air vent 101 on one side, is filtered by the filter material, and is discharged from the air vent 101 on the other side of the filter material box 10, and then enters the collection box 2 through the gas pipe 5 and the connecting pipe 9, so as to complete the whole filtering and purification operation.

[0027] like Figure 4 and Figure 5 As shown, a carrying rod 11 is fixedly connected to the inner wall of the filter material box 10 near the box cover 7, and the side of the carrying rod 11 away from the filter material box 10 abuts against the box cover 7. When the filter material inside the filter material box 10 needs to be replaced, the filter material box 10 can be pulled out from the filter box 4 through the carrying rod 11, so as to replace the filter material, which is convenient for taking the filter material box 10.

[0028] like Figure 4 and Figure 5 As shown, two symmetrically arranged mounting grooves 102 are provided on both sides of the filter material box 10, and symmetrically arranged mounting bars 12 are fixedly connected on both sides of the filter box 4, and the two mounting bars 12 are respectively slidably connected with the two mounting grooves 102. Through the connection and fixation between the mounting bars 12 and the mounting grooves 102, the filter material box 10 in the filter box 4 can be limited and fixed, so as to prevent the filter material box 10 from moving when the helium enters the filter box 4 through the gas pipe 5 and impacts the filter material box 10, thereby improving the stability of the filtering process.

[0029] like Figure 4 As shown, there is a certain gap between the outer walls of the filter material box 10 on both sides near the plurality of vents 101 and the inner walls of the filter box 4 on both sides. By setting a certain gap between the two sides of the vents 101 of the filter material box 10 and the filter box 4, helium can enter the filter box 4 through the gas pipe 5, pass through the gaps for buffering, and then enter the filter material box 10 through the vents 101, reducing the impact of helium on the filter material box 10 and the internal filter material, so that helium can enter the filter material box 10 more evenly for filtration, further improving the filtering effect of helium.

[0030] like Figure 1 - Figure 4 As shown, the locking member 13 is a buckle structure, and one end is fixedly connected to the filter box 4, and the other end is fixedly connected to the box cover 7. The locking member 13 is designed as a buckle structure, which can be more convenient to operate when the box cover 7 closes the filter box 4. At the same time, the fastening of the buckle is used to further improve the connection airtightness between the box cover 7 and the filter box 4, and improve the airtightness of the filter box 4, wherein the buckle structure is an existing structure.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
