Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] An adsorption-type waste gas purification device includes a base 1, a purification box 4 and a washing box 5 are disposed on the top of the base 1, and a uniform distribution mechanism 2 is disposed inside the purification box 4 for uniformly distributing the airflow. The uniform distribution mechanism 2 includes:

[0027] The rotating unit 21 is located inside the purification box 4 and includes a fixed plate 211 fixedly installed inside the base 1. A rotating tube 212 is rotatably installed inside the fixed plate 211, and an air jet assembly 3 is provided on the outer side of the bottom end of the rotating tube 212. The airflow is evenly distributed by rotating the rotating tube 212.

[0028] The drive unit 22 is disposed above the fixed plate 211 and is used to drive the rotating unit 21.

[0029] In this embodiment, a connecting pipe 215 is rotatably installed inside the rotating tube 212, and a turntable 213 is fixedly installed on the surface of the rotating tube 212. A number of linkage teeth 214 are installed in a circular array at the bottom of the turntable 213.

[0030] The first drive tooth 226 and the second drive tooth 227 are respectively inserted into the space between multiple linkage teeth 214 to realize the rotation of the turntable 213. The rotation of the turntable 213 drives the rotating tube 212 to rotate synchronously. The rotating tube 212 drives the five jet components 3 to rotate synchronously. The exhaust gas enters the activated carbon layer in the middle of the partition inside the base 1 through the jet components 3, thereby avoiding uneven airflow distribution that leads to low adsorbent utilization.

[0031] In this embodiment, the jet assembly 3 includes five connecting pipes 31 fixedly installed on the outside of the base 1. A threaded sleeve 33 is rotatably installed on the surface of the connecting pipe 31, and a jet pipe 36 is fixedly installed at one end of the connecting pipe 31. The connecting pipe 31 is connected to the jet pipe 36 by being rotatably installed on the surface of the jet pipe 36 through the threaded sleeve 33.

[0032] By rotating the threaded sleeve 33, the threaded sleeve 33 is separated from the jet pipe 36, and the jet pipe 36 is pulled out. Simultaneously, the insert 35 is pulled out of the interior of the insertion hole 32, thereby disassembling the jet assembly 3. This facilitates cleaning of the inside of the jet pipe 36 and prevents the jet head 37 from being blocked due to the accumulation of exhaust gas particles inside the jet pipe 36.

[0033] In this embodiment, a set of insertion holes 32 are provided at one end of the connecting pipe 31, and a set of insertion posts 35 are fixedly installed at one end of the jet pipe 36. The jet pipe 36 is positioned and connected to the connecting pipe 31 by inserting the insertion posts 35 into the insertion holes 32. Four jet heads 37 are fixedly installed at the bottom of the jet pipe 36, and rubber pads 34 are fixedly installed at both ends of the threaded rotating sleeve 33.

[0034] The rubber pads 34, which are fixedly installed at both ends of the threaded swivel 33, prevent air leakage at the connection between the jet pipe 36 and the connecting pipe 31.

[0035] In this embodiment, the drive unit 22 includes a sliding seat 221 fixedly installed on the top of the fixed plate 211. A cross slide plate 222 is slidably installed inside the sliding seat 221. A first drive tooth 226 and a second drive tooth 227 are fixedly installed on the top of the cross slide plate 222. The first drive tooth 226 and the second drive tooth 227 are respectively in contact with the linkage tooth 214 through the sliding of the cross slide plate 222, so as to realize the rotation of the turntable 213. A motor 223 is fixedly installed at the bottom of the fixed plate 211. A drive disk 224 is fixedly installed through the fixed plate 211 at the output end of the motor 223. A linkage rod 225 is rotatably installed on the top of the drive disk 224. One end of the linkage rod 225 is rotatably connected to one end of the cross slide plate 222.

[0036] The motor 223 is an OMV800 model. It is electrically connected to an external power source and can be opened and closed by a human-operated control panel. The operation of the motor 223 drives the drive disk 224 to rotate. The drive disk 224 drives the cross slide plate 222 to move back and forth through the linkage rod 225. The cross slide plate 222 drives the first drive tooth 226 and the second drive tooth 227 to move back and forth synchronously. The first drive tooth 226 and the second drive tooth 227 are inserted into the space between multiple linkage teeth 214 in sequence, so as to realize the rotation of the turntable 213.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] During operation, firstly, the exhaust gas enters the interior of the washing tank 5 for washing. After washing, it enters the interior of the connecting pipe 215 through a pump. At the same time, the motor 223 runs and drives the drive disc 224 to rotate. The drive disc 224 drives the cross slide plate 222 to move back and forth through the linkage rod 225. The cross slide plate 222 drives the first drive tooth 226 and the second drive tooth 227 to move back and forth synchronously. The first drive tooth 226 and the second drive tooth 227 are inserted into the space between multiple linkage teeth 214 in sequence, so as to realize the rotation of the turntable 213. The rotation of the turntable 213 drives the rotating pipe 212 to rotate synchronously. The rotating pipe 212 drives the five jet components 3 to rotate synchronously. The exhaust gas enters the interior of the connecting pipe 31 and the jet pipe 36, and is sprayed out through the jet head 37. It enters the activated carbon layer in the middle of the partition inside the base 1 for adsorption and purification.

[0039] Then, by rotating the threaded sleeve 33, the threaded sleeve 33 is separated from the jet pipe 36, the jet pipe 36 is pulled out, and the insert 35 is simultaneously pulled out of the interior of the insertion hole 32, the jet assembly 3 is disassembled, and the interior of the jet pipe 36 is cleaned.
