The gas purifying apparatus 10 is correspondingly communicated with one guide tube 422 through the end of each purifying module 421, and when the guide tube 422 is communicated with the vent hole 131 covered by the gas inlet box 132, the gas inlet tube 200 can introduce the gas to be purified into the purifying module 421 through the gas inlet box 132 and the guide tube 422.

The air-tight connection structure is not required between the base 110, the housing 120 and the air guide block 130, and only the detachable connection is required. Therefore, after the gas to be purified enters through the gas inlet pipe 200, the gas does not enter the inner space formed between the base 110, the housing 120 and the air guide block 130, and the inner space is only used for installing the purification assembly 400. The gas to be purified enters from the gas inlet pipe 200 and then is discharged from the gas outlet pipe 300 through the purifying screen 420.
As shown in fig. 3, in one embodiment, the casing 100 further includes a plurality of support legs 140, and each support leg 140 is installed on the base 110. Further, the distance between two adjacent supporting feet 140 is equal. Each of the supporting legs 140 is detachably connected to the base 110, and the height of the connection between each of the supporting legs 140 and the base 110 is adjustable. Optionally, the supporting legs 140 have an elastic buffer function to absorb the vibration generated when the motor 520 operates. Thus, the effect of the plurality of supporting legs 140 can make the whole gas purification device have a distance from the ground, and the connection height between each supporting leg 140 and the base 110 is adjustable, so that the whole gas purification device can be in a horizontal state according to the ground flatness of different installation environments, so that the purification assembly 400 and the power assembly 500 work in the horizontal state environment, unnecessary load caused by inclination is avoided, and the service life is prolonged.
As shown in fig. 3, in one embodiment, the air guide block 130 is provided with a rotation hole 136, and the rotation shaft 410 is rotatably connected to the output end of the power assembly 500 after passing through the rotation hole 136. In one embodiment, the air guide block 130 is provided with a bearing in the rotation hole 136, and the rotation shaft 410 passes through and is sleeved in the bearing, so that the rotation shaft 410 is in sliding abutting relationship with the edge of the rotation hole 136, and the rotation shaft 410 rotates more smoothly. Therefore, the rotating shaft 410 can rotate more smoothly under the function of the bearing, and the service life of the rotating shaft 410 is effectively prolonged. In this embodiment, since the entire gas purifying apparatus is shaped like a cylinder, the rotation hole 136 is formed in the middle region of the gas guide block 130.
The gas guiding block 130, which may also be referred to as a cover plate, cooperates with the base 110 and the housing 120 to guide the inlet gas and the outlet gas, i.e., the gas is introduced into the purifying assembly 400 from the inlet tube 200 and then is introduced out of the purifying assembly 400 to the outlet tube 300, and the gas guiding block 130 serves as a gas flow direction guiding function, and is referred to as a gas guiding block. Since the power assembly 500 drives the purification assembly 400 to rotate and the purification assembly 400 is located in the casing 100, in various embodiments of the present invention, the air guide block 130 is configured to have a substantially cylindrical plate-like structure to fit the casing 120 and the base 110. That is, the housing 120 is a hollow cylinder with two open sides, and the base 110 is also a cylinder structure. The housing 120 has a purification chamber 121, the base 110 and the air guide block 130 cover the purification chamber 121, and the rotation shaft 410 and the purification screen 420 are respectively accommodated in the purification chamber 121. In this way, the casing 100 composed of the base 110, the housing 120 and the air guide block 130 is a cylindrical structure as a whole, so that the purification assembly 400 installed in the casing 100 can freely and flexibly rotate under the action of the power assembly 500.
As shown in fig. 3 and 4, the air inlet box 132 and the air outlet box 133 cover the plurality of vent holes 131 formed in the air guide block 130, that is, under the combined action of the air inlet box 132 and the air outlet box 133, the plurality of vent holes 131 formed in the air guide block 130 are covered, so as to prevent the phenomenon of gas leakage from the uncovered vent holes 131. Further, the air inlet box 132 and the air outlet box 133 are both arc-shaped structures. Further, the arc length of the inlet box 132 is smaller than the arc length of the outlet box 133. In this embodiment, the number of the ventilation holes 131 covered by the inlet box 132 is less than the number of the ventilation holes 131 covered by the outlet box 133, which is to achieve better purification effect, because the number of the ventilation holes 131 covered by the inlet box 132 is small, the gas to be purified will enter the guide tube 422 communicating with the ventilation holes 131 under the area covered by the inlet box 132 from a small number of the ventilation holes 131, and the gas will flow through the plurality of purification modules 421 and then be discharged from the guide tube 422 communicating with the ventilation holes 131 under the area covered by the outlet box 133, at this time, the gas is purified, and flows intensively through the outlet box 133, enters the outlet tube 300, and then enters the filling bottle.

Similarly, the air inlet pipe connector 134 is hermetically connected with the surface of the air guide block 130. The intake pipe 200 communicates with the intake pipe joint 134. In the air intake process, the air intake pipe 200 is filled with the gas to be purified, the gas to be purified enters the air intake passage 1321 through the air intake pipe joint 134, and then enters the vent holes 131 communicated with the air intake passage 1321 through the air intake passage 1321, so as to enter the guide pipes 422 correspondingly communicated with the vent holes 131, the gas to be purified further enters the purification module 421 to be purified, and the purification module 421 is filled with purification materials, such as molecular sieves and activated carbon.

The respective purification modules 421 are communicated with each other inside, and the respective guide pipes 422 are communicated by the respective purification modules 421 communicated with each other. Therefore, when a part of the guide pipes 422 is filled with gas, the other part of the guide pipes 422 can discharge the purified gas, so that the purification material in each purification module 421 can be fully utilized by continuously replacing the guide pipes 422 filled with gas, and the problem that the traditional purification material close to the gas inlet end consumes more purification material than the gas outlet end, which causes uneven utilization of the purification material, wastes resources when the purification screen 420 is replaced, and invisibly increases the purification cost is avoided.
Alternatively, a plurality of purification modules 421 and a plurality of guide pipes 422 are integrally formed to form the purification screen 420, which may increase the strength of the entire structure. Optionally, the spacing between two adjacent purification modules 421 is equal. This allows the rotation angle of the motor 520 at each time to be set such that the purification screen 420 is stably rotated by the motor 520 while the purification screen 420 maintains a stable connection with the air guide block 130.
As shown in fig. 10, 11 and 12, a purification space 4211 is formed in the purification module 421, the purification space 4211 communicates with the inside of the guide tube 422, and the purification space 4211 is filled with a purification material. The respective purification modules 421 are communicated with each other in the region of the rotation shaft 410 to form a communication space 4212, the communication space 4212 is in a ring structure, and the respective purification spaces 4211 are communicated with each other through the communication space 4212.
To further improve the utilization of the purification material, the communication spaces 4212 are located in the bottom region of the purification sieve 420, that is, the respective purification spaces 4211 are communicated only through the narrower communication spaces 4212. In this way, after entering the purification space 4211 of one purification module 421 from the guide pipe 422, the gas needs to pass through most of the purification space 4211, so that after contacting most of the purification material, the gas can enter the purification space 4211 of another purification module 421 through the narrow communication space 4212. Thus, by disposing the communicating space 4212 in the bottom region of the purifying screen 420 and disposing the communicating space 4212 as a narrow space, the flow of gas between different purifying spaces 4211 needs to flow through most of the purifying materials, which can greatly improve the utilization rate of the purifying materials.
It should be noted that the present invention also provides a gas purification method 20, and the gas purification method 20 is applied to the gas purification apparatus in any of the above embodiments.
As shown in fig. 13, the gas purification method 20 includes the steps of:
s101, before starting up each purification operation, starting a motor to rotate a purification sieve so as to enable each guide pipe to rotate to a next vent hole in the rotation direction and be communicated with the vent hole;
s102, introducing gas to be purified from a gas inlet pipe into a purification sieve along part of vent holes of a gas guide block;
s103, collecting purified gas from the other part of vent holes after passing through the purification sieve;
s104, introducing the purified gas into a filling bottle.
According to the gas purification method 20, before starting up of each purification operation, the motor is controlled to rotate to drive the purification sieve to rotate, each guide pipe is made to rotate to the next vent hole in the rotation direction and is communicated with the vent hole, so that the purification sieve is different from the position of the last purification operation before the purification operation, the position of the purification sieve is continuously adjusted, and before the position adjustment process is performed each time of the purification operation, the introduction and purification of gas to be purified are not influenced, the utilization rate of purification materials is effectively improved, the purification sieve is convenient to replace, and the gas purification cost is reduced.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
