[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-6 , the present invention provides a technical solution: a molecular sieve adsorber that is convenient for replacement, including a limit mechanism 1 and a negative pressure pump 103 installed on one side of the limit mechanism 1; a dust cleaning mechanism 2 is arranged on one side inside the limit mechanism 1, and a driving motor 204 is installed at one end of the dust cleaning mechanism 2; the limit mechanism 1 includes a base 101, and an adsorber body 102 is fixedly connected to one side of the top of the base 101. One side of the adsorber body 102 is fixedly connected to the negative pressure pump 103, and the bottom of the negative pressure pump 103 is fixedly connected to the base 101. By setting the negative pressure pump 103, it is convenient for gas to flow inside the adsorber body 102;

[0031] An intake pipe 104 is fixedly connected to one side of the top of the adsorber body 102. A filter frame 105 is snap-fitted to one side inside the adsorber body 102. A molecular sieve packing mesh layer 106 is snap-fitted to one side inside the filter frame 105. An activated carbon packing mesh layer 107 is snap-fitted to one side of the filter frame 105 close to the molecular sieve packing mesh layer 106. By setting the molecular sieve packing mesh layer 106 and the activated carbon packing mesh layer 107, the gas can be fully filtered;

[0032] The left and right sides of the top of the filter frame 105 are symmetrically and fixedly connected with first limit blocks 108. A groove 109 is opened inside the first limit block 108. One side inside the groove 109 is rotatably connected with a spring 110. The outside of the first limit block 108 is in fit connection with the adsorber body 102;

[0033] One end of the spring 110 is rotatably connected to a pull rod 111. The end of the pull rod 111 away from the spring 110 is fixedly connected to a semi-sphere 112. The center position inside the semi-sphere 112 is rotatably connected to a first limit post 113. Both the front and rear ends of the first limit post 113 are fixedly connected to the first limit block 108. By arranging the spring 110, the semi-sphere 112 can be in an inclined state without being affected by external forces, and the first limit block 108 and the second limit block 115 can be limited;

[0034] On the side of the first limit post 113 close to the semi-sphere 112, a triangular block 114 is fixedly connected. The outer side of the triangular block 114 is in close contact with a second limit block 115. The side of the second limit block 115 away from the filter frame 105 is fixedly connected to the adsorber body 102. The internal structure of the second limit block 115 is the same as that of the first limit block 108;

[0035] The dust cleaning mechanism 2 includes a collection box 201. The bottom of the collection box 201 is slidably connected to the adsorber body 102. Above the adsorber body 102 close to the collection box 201, a bracket 202 is fixedly connected. A filter element 203 is fixedly connected inside the bracket 202. By arranging the filter element 203, the gas can be preliminarily filtered;

[0036] On one side of the adsorber body 102 close to the collection box 201, a driving motor 204 is fixedly connected. The output end of the driving motor 204 is fixedly connected to a disc 205. On one side of the disc 205, a cylinder 206 is fixedly connected. A connecting rod 207 is sleeved outside the cylinder 206. Inside one end of the connecting rod 207, a second limit post 208 is rotatably connected. Both the front and rear ends of the second limit post 208 are fixedly connected to the adsorber body 102. By driving the disc 205 and the cylinder 206 to rotate by the driving motor 204, the connecting rod 207 is driven by the cylinder 206 to swing left and right around the second limit post 208;

[0037] On the side of the connecting rod 207 close to the second limit post 208, a rack 209 is meshed. Limit sleeves 210 are sleeved outside both the left and right ends of the rack 209. One side of each of the two limit sleeves 210 is fixedly connected to the adsorber body 102. By the meshing action between the connecting rod 207 and the rack 209, the rack 209 can be driven to move left and right to knock the filter element 203. The vibration generated by the knocking can clean the dust on the surface of the filter element 203.

[0038] Working principle: Before using this easily replaceable molecular sieve adsorber, it is necessary to first check the overall condition of the device to ensure that it can work properly. According to Figure 1 - Figure 6As shown, first, start the negative pressure pump 103 to suck air into the adsorber body 102 from the air inlet pipe 104. The gas first passes through the filter element 203 to discharge impurities such as dust in the gas, and then the gas passes through the activated carbon packing mesh layer 107 and the molecular sieve packing mesh layer 106 for in-depth purification treatment, and finally is discharged from the negative pressure pump 103;

[0039] Secondly, when it is necessary to replace the activated carbon packing mesh layer 107 and the molecular sieve packing mesh layer 106, turn the handle 111 downward to drive the semi-sphere 112 to rotate around the first limit post 113. While stretching the spring 110, the semi-sphere 112 in the second limit block 115 also rotates around the first limit post 113, so as to release the limit of the semi-sphere 113 on the first limit block 108 and the second limit block 115, and the filter frame 105 can be taken out of the adsorber body 102, which is convenient for replacing the molecular sieve packing mesh layer 106 and the activated carbon packing mesh layer 107;

[0040] Finally, when it is necessary to clean the ash on the filter element 203, start the drive motor 204 to drive the disc 205 and the cylinder 206 to rotate. Use the cylinder 206 to drive the connecting rod 207 to swing left and right around the second limit post 208. Utilize the meshing effect between the connecting rod 207 and the rack 209, and the rack 209 can be driven to move left and right to knock on the filter element 203. The vibration generated by the knocking can clean the dust on the surface of the filter element 203 and prevent the filter element 203 from being blocked during long-term operation.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
