[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-5 The utility model provides a technical solution: a helium recovery and purification device, including a pump body 10, an air inlet 20, a partition 30, a placement groove 301, a gasket 302, a spring 303, a filter layer 304, a blocking plate 1 305, a reaction chamber 306, a slider 307, a receiving groove 308, a blocking plate 2 309, an air outlet 40, a perspective plate 401, a moisture absorption layer 402 and a streamer 403;

[0031] The helium recovery and purification device improves the purification effect, and the specific implementation method is as follows:

[0032] The pump body 10 is configured as a cavity structure, and an air inlet 20 is installed on the surface of the pump body 10; a filtering mechanism is arranged inside the pump body 10, and the filtering mechanism includes: a partition 30 is symmetrically installed inside the pump body 10, and a placement groove 301 is slidably installed on the surface of the partition 30, a gasket 302 is embedded inside the placement groove 301, and a spring 303 is connected to the inner wall of the gasket 302, a filtering layer 304 is embedded inside the placement groove 301, and one side of the placement groove 301 passes through the pump body 10 and is connected to a blocking plate 305, and the blocking plate 305 is arranged on the outside of the pump body 10, a reaction chamber 306 is installed on the inner wall of the pump body 10, and a slider 307 is symmetrically fixedly connected to the inner wall of the pump body 10, a receiving groove 308 is installed on the surface of the slider 307, and the other side of the receiving groove 308 The end passes through the pump body 10 and is connected with a second blocking plate 309, and the second blocking plate 309 is arranged on the outside of the pump body 10, the partition plate 30 and the placement groove 301 are slidably connected, and the placement groove 301 and the pump body 10 are slidably connected, the filter layer 304 and the gasket 302 are slidably connected, and the gasket 302 is arranged as a flexible mechanism, the bottom of the filter layer 304 is connected to the surface of the spring 303, the blocking plate 1 305 and the pump body 10 are slidably connected, the inside of the pump body 10 is provided with an opening, and the opening of the pump body 10 is slidably connected to the placement groove 301, the receiving groove 308 is arranged at the bottom of the reaction chamber 306, and the receiving groove 308 and the slider 307 are slidably connected, the surface of the pump body 10 is provided with an opening, and the receiving groove 308 and the opening of the pump body 10 are slidably connected.

[0033] The gas enters the pump body 10 through the air inlet 20, causing the gas to move downward, and at this time, the gas moves to the placement groove 301. At this time, the gas moves to the filter layer 304, and the gas creates a thrust on the filter layer 304, causing the filter layer 304 to move downward inside the placement groove 301. At this time, the filter layer 304 drives the spring 303 to contract, and the filter layer 304 moves on the surface of the gasket 302. The gasket 302 can protect the filter layer 304, prevent the filter layer 304 from hitting, and reduce noise. At this time, the filter layer 304 filters the gas, and at the same time, the filter layer 304 absorbs the dust inside the gas. When the filter layer 304 vibrates, the dust on the surface can be shaken off to the inner wall of the placement groove 301, and the filtered gas moves downward through the placement groove 301 and moves to the inside of the reaction chamber 306. The gas is purified by the reaction chamber 306, and the impurities produced by the purification fall into the inside of the receiving groove 308. After the reaction is completed, the blocking plate 1 305 and the blocking plate 2 309 are pulled, and the blocking plate 1 305 and the blocking plate 2 309 respectively drive the placement groove 301 and the receiving groove 308 to move outward. At this time, the filter layer 304 inside the placement groove 301 can be replaced, and the impurities inside the receiving groove 308 can be adsorbed at the same time.

[0034] The helium recovery and purification device is convenient for observing whether the purification is completed and preventing gas leakage. The specific implementation method is as follows:

[0035] The bottom of the pump body 10 is connected to an air outlet 40, and a warning mechanism is arranged inside the air outlet 40, and the warning mechanism includes: a hygroscopic layer 402 is embedded in the air outlet 40, and a ribbon 403 is installed at the bottom of the hygroscopic layer 402, a perspective plate 401 is embedded in the surface of the air outlet 40, the ribbon 403 is arranged at the bottom of the hygroscopic layer 402, and the positions of the ribbon 403 and the perspective plate 401 are arranged correspondingly.

[0036] The filtered gas moves from the pump body 10 to the inside of the air outlet 40, so that the gas flows inside the air outlet 40. When the gas moves to the inside of the hygroscopic layer 402, the hygroscopic layer 402 absorbs the moisture inside the gas and dries the gas. At the same time, the gas impacts the hygroscopic layer 402, and the hygroscopic layer 402 vibrates and makes a sound. At this time, the gas moves to the ribbon 403, and the gas drives the ribbon 403 to float. The ribbon 403 can be observed through the perspective plate 401, and whether the gas purification is completed can be judged by whether the ribbon 403 floats and the sound produced by the vibration of the hygroscopic layer 402.

[0037] Working principle: When using the helium recovery and purification device, a placement tank 301, a filter layer 304, a blocking plate 305 and a reaction chamber 306 are provided to improve the purification effect. A perspective plate 401, a moisture absorption layer 402 and a streamer 403 are provided to facilitate observation of whether the purification is completed, prevent gas leakage, and increase the overall practicality.
