[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0028] See also Figure 1-4 The utility model provides a technical solution: a helium recovery machine, including a shell 1, an air inlet 2, a separation chamber 3, a partition 4, an inclined plate 5, a connecting pipe 6, a connecting port 7, an upper air port 8, a discharge pipe 9, an adsorption box 10, a helium separation membrane 11, a detection chamber 12, an air suction pump 13, a helium detector 14, and a circulation pipe 15.

[0029] Example 1

[0030] The helium recovery machine is provided with a helium separation structure, which performs double separation through the adsorption box 10 and the helium separation membrane 11 to achieve a better separation effect, specifically:

[0031] The front surface of the shell 1 is provided with an air inlet 2, and the separation chamber 3 is installed inside the shell 1. A helium separation structure is provided inside the shell 1. The helium separation structure can reduce the internal temperature through the connecting pipe 6 and separate the helium from other gases through the adsorption box 10. The helium separation structure includes a partition 4, which is fixedly installed on the inner wall surface of the separation chamber 3. Inclined plates 5 are arranged at equal vertical intervals inside the separation chamber 3. A connecting pipe 6 is embedded in the inner wall of the inclined plate 5, and connecting ports 7 are respectively provided at both ends of the connecting pipe 6, and the connecting port 7 passes through the front and back surfaces of the shell 1. An upper air port 8 is provided on the upper surface of the partition 4, and a lower surface of the partition 4 is connected with a discharge pipe 9. The lower end of the discharge pipe 9 passes through the lower surface of the separation chamber 3 and is connected with the upper surface of the adsorption box 10. The adsorption box 10 is installed on the bottom surface of the inner wall of the shell 1, and the upper end of the upper air port 8 passes through the lowest inclined plate 5;

[0032] When the helium recovery machine recovers helium, it first allows the gas to enter the separation chamber 3 through the air inlet 2 on the front surface of the shell 1. A partition 4 is installed on the inner wall surface of the separation chamber 3. The gas will first be below the partition 4 in the separation chamber 3, and then the gas will reach the top of the partition 4 through the upper air port 8. Furthermore, inclined plates 5 are arranged vertically and evenly spaced inside the separation chamber 3, and a connecting pipe 6 is embedded in the interlayer of the inclined plate 5. Both ends of the connecting pipe 6 are connected with connecting ports 7. At this time, the connecting port 7 is connected to the coolant tank so that the coolant flows in the connecting pipe 6, thereby reducing the temperature inside the separation chamber 3. Then the helium in the gas will settle downward under the low temperature environment, and then the helium will enter the adsorption box 10 through the discharge pipe 9, and the adsorption material in the helium adsorption box 10 will be adsorbed in the adsorption box 10.

[0033] Example 2

[0034] The helium recovery machine is also provided with a circulation structure, so that the gas is separated again through the circulation pipe 15, making the separation more thorough, specifically:

[0035] The interior of the shell 1 is also provided with a circulation structure, which can detect the separated gas through a helium detector 14 and then circulate and separate the gas again. The detection chamber 12 is fixedly mounted on the upper surface of the inner wall of the shell 1, and the lower end of the detection chamber 12 is connected with the upper surface of the separation chamber 3. A helium separation membrane 11 is installed at the connection between the detection chamber 12 and the separation chamber 3, and an air suction pump 13 is installed on the upper surface of the inner wall of the detection chamber 12. A helium detector 14 is installed on the bottom surface of the inner wall of the detection chamber 12. A circulation pipe 15 is connected to the side surface of the detection chamber 12, and the other end of the circulation pipe 15 is installed on the side surface of the separation chamber 3. The circulation pipe 15 is set as a C-shaped structure, and an air outlet is provided on the upper surface of the shell 1;

[0036] Furthermore, the suction pump 13 is turned on, and the suction pump 13 causes the gas to move upward, and then the gas will pass through the helium separation membrane 11 installed at the connection end of the detection chamber 12 and the separation chamber 3. The helium is blocked by the helium separation membrane 11, and the other part of the gas will continue to move upward, and then the gas will enter the detection chamber 12. Figure 4 As shown, the helium detector 14 in the detection chamber 12 will detect the helium content in the dry toilet gas. When the gas still contains helium, the helium will flow through the circulation pipe 15 of the C-shaped structure. Since the other end of the circulation pipe 15 is installed on the side surface of the separation chamber 3, the gas will enter the separation chamber 3 again, so that the gas will be separated again, which will increase the recovery rate of helium and reduce the waste of helium.

[0037] Working principle: When using the helium recovery machine, a helium separation structure is provided. The connecting pipe 6 in the inclined plate 5 reduces the internal temperature so that the helium enters the adsorption box 10 for adsorption separation. A circulation structure is also provided, which can detect the separated gas through the circulation pipe 15 and then re-enter the separation chamber 3, thereby increasing the overall practicality.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
