The activated carbon adsorption tank 220 is disposed between the air supply pipe 210 and the exhaust pipe 230, and detachably engaged with both the air supply pipe 210 and the exhaust pipe 230. The air supply pipe 210 is used for supplying the exhaust gas to the activated carbon adsorption tank 220 for adsorption treatment, and the gas after adsorption treatment enters the exhaust pipe 230 and is discharged into the exhaust passage 400.

After the sealing airbag 240 is inflated, the gap between the air supply pipe 210 and the communication port 221 and the gap between the exhaust pipe 230 and the communication port 221 are closed, so that the air supply pipe 210 and the communication port 221 and the exhaust pipe 230 and the communication port 221 can be quickly butted, and the assembly efficiency is greatly improved on the premise of ensuring the sealing property.
It should be noted that, precisely because the assembly and connection efficiency is greatly improved, the disassembly and assembly can be completed more quickly, the risk of exhaust gas leakage is lower, the risk of toxic substance overflow is also lower, and the safety is also improved.

In addition, in the replacement process, the risk of harmful substance leakage can be effectively reduced, and the safety is greatly improved.
In the present embodiment, both the air supply pipe 210 and the exhaust pipe 230 are coaxially disposed. The activated carbon adsorption tank 220 is fixedly installed along the axial direction of the air supply pipe 210 and the air discharge pipe 230. A guide rail (not shown) is further provided between the air supply pipe 210 and the air exhaust pipe 230, the guide rail is disposed perpendicular to the air supply pipe 210 and the air exhaust pipe 230, and the activated carbon adsorption box 220 is slidably fitted to the guide rail, thereby facilitating a quick replacement of the activated carbon adsorption box 220.
The air supply pipe 210 and the air discharge pipe 230 are symmetrically arranged in structure, and the air supply pipe 210 is described in detail here as an example.
The inner diameter of the air supply pipe 210 is the same as the inner diameter of the communication port 221, and the outer diameter of the air supply pipe 210 is larger than the inner diameter of the communication port 221. When the air supply pipe 210 is aligned with the communication port 221 of the activated carbon adsorption tank 220, the air supply pipe 210 and the communication port 221 are coaxially disposed.
Referring to fig. 1 to 8, the matching cover 222 has a first inner wall 222a and a second inner wall 222b.
The first inner wall 222a is disposed perpendicular to the axial direction of the communication opening 221 and surrounds the communication opening 221, and the first inner wall 222a is annular.
The second inner wall 222b is perpendicular to the first inner wall 222a and connected to the outer end of the first inner wall 222a, the second inner wall 222b is located on a side of the first inner wall 222a away from the activated carbon adsorption tank 220, and the second inner wall 222b continuously extends in a ring shape along the circumferential direction of the first inner wall 222a.
The first inner wall 222a and the second inner wall 222b constitute inner side walls of the fitting housing 222.
When the air feed pipe 210 is aligned with the communication port 221 of the activated carbon adsorption tank 220, a gap is provided between both the first and second inner walls 222a and 222b and the end of the air feed pipe 210. After the airbag 240 is inflated, the airbag 240 simultaneously engages the first inner wall 222a and the second inner wall 222b.
With this design, after the air bag 240 is inflated, not only sealing can be achieved, but also the activated carbon adsorption tank 220 can be stabilized, and the stability of the fitting between the air supply pipe 210 and the communication port 221 can be improved.
Further, the exhaust treatment module 200 further includes: a first electrically operated valve 251, a first trigger button 252 and a first controller (not shown).
The first motor-operated valve 251 is provided in the air supply pipe 210 to control opening and closing of the air supply pipe 210, and the first motor-operated valve 251 is provided near the mouth of the outlet end of the air supply pipe 210. The first electric valve 251 is electrically connected to a first controller, and the first controller is used for controlling the first electric valve 251. The first trigger button 252 is electrically connected to the first controller for providing an indication signal to the first controller.
The sealing airbag 240 attached to the air supply pipe 210 is fixedly connected to the end surface of the air supply pipe 210 on the side close to the end surface of the air supply pipe 210. The sealing air bag 240 is provided continuously with the end surface of the air supply pipe 210 along the circumferential direction of the end surface of the air supply pipe 210.
The first trigger button 252 is fitted to the end surface of the air supply pipe 210 and exposed to the end surface of the air supply pipe 210, and the first trigger button 252 is provided near a connection portion between the air bag 240 and the air supply pipe 210.
When the first electrically-operated valve 251 is normally closed, and the sealing airbag 240 is inflated, the sealing airbag 240 comes into contact with a space between the end surface of the exhaust pipe 230 and the fitting cover 222, the sealing airbag 240 is fully expanded by the reaction force of the fitting cover 222 and comes into contact with the end surface of the air supply pipe 210, and the sealing airbag 240 presses and triggers the first trigger button 252. After detecting that the first triggering button 252 is triggered, the first controller controls the first electric valve 251 to open.
In this way, after the air feeding pipe 210 is matched with the communication port 221 of the activated carbon adsorption box 220, the air feeding pipe 210 is opened, thereby preventing the waste gas from leaking and improving the safety of the treatment process. In addition, when the sealing airbag 240 is accidentally deflated or has insufficient pressure, or when the air supply pipe 210 and the communication port 221 are accidentally displaced relative to each other, the sealing airbag 240 cannot fully press the first trigger button 252 to trigger the first trigger button, so that the first electrically operated valve 251 is closed to prevent the exhaust gas from leaking.
Alternatively, the first trigger button 252 may be triggered only when it is fully pressed, and in this embodiment, it is set as: when the outer side of the airbag 240 is closely attached to the end surface of the air supply pipe 210, the first trigger button 252 is pressed down to be flush with the end surface of the air supply pipe 210, and the first trigger button 252 is triggered. The triggering pressure of the first triggering button 252 can be flexibly adjusted according to actual conditions.
In the present embodiment, the number of the first triggering buttons 252 is plural, and the plural first triggering buttons 252 are distributed along the circumferential direction of the air bag 240. After detecting that all the first trigger buttons 252 are triggered, the first controller controls the first electrically operated valve 251 to open.
Alternatively, the first trigger button 252 may be provided in plurality, and the first trigger button 252 may be provided on both sides of the connection portion of the air bag 240 and the air supply pipe 210. The first trigger buttons 252 are distributed along the circumferential direction of the sealing balloon 240 on both sides of the connection portion of the sealing balloon 240 and the air supply tube 210. After detecting that all the first trigger buttons 252 are triggered, the first controller controls the first electrically operated valve 251 to open.
With this design, the first electrically operated valve 251 is opened only after the airbag 240 is completely deployed and sufficiently attached between the air supply pipe 210 and the mating cover 222 to sufficiently close the gap between the air supply pipe 210 and the communication port 221.
In order to enable the air bag 240 to trigger the first trigger button 252 more effectively, a first hard push plate 241 is fixedly connected to the outer side of the air bag 240, and the position of the first hard push plate 241 matches the position of the first trigger button 252. After the air bag 240 is inflated, the first hard push plate 241 presses the trigger first trigger button 252. The first hard push plates 241 are a plurality of first hard push plates 241, and the first hard push plates 241 are arranged at intervals. The first hard push plate 241 can increase the force of the sealing air bag 240 on the first trigger button 252, so that the sealing air bag 240 can accurately press the first trigger button 252.
In this connection, the exhaust gas treatment module 200 further includes: a second electrically operated valve 261, a second trigger button 262 and a second controller (not shown in the figure).
The second electrically operated valve 261 is provided in the communication port 221 for controlling opening and closing of the communication port 221, and the second electrically operated valve 261 is provided near the mouth of the communication port 221. The second electric valve 261 is electrically connected to a second controller, and the second controller is configured to control the second electric valve 261. The second trigger button 262 is electrically connected to the second controller for sending an indication signal to the second controller. The second trigger button 262 is embedded in the first inner wall 222a and exposed out of the first inner wall 222a.
The second electric valve 261 is in a normally closed state, after the sealed air bag 240 is inflated, the sealed air bag 240 abuts against the first inner wall 222a and presses the triggering second triggering button 262, and after the second controller detects that the second triggering button 262 is triggered, the second electric valve 261 is controlled to be opened. In this embodiment, the second trigger buttons 262 are also multiple and uniformly spaced along the circumferential direction of the first inner wall 222a, and the second controller detects that all the second trigger buttons 262 are triggered, and then controls the second electrically operated valve 261 to open.
Through this design, the same security that has improved activated carbon adsorption case 220 avoids new activated carbon to receive the external pollution by accident on the one hand, and on the other hand also avoids that the harmful substance spills over from activated carbon adsorption case 220.
And a second hard push plate 242 is fixedly connected to the outer side of the air bag 240, and the position of the second hard push plate 242 is matched with the position of the second trigger button 262. After the sealed air bag 240 is inflated, the second hard push plate 242 presses the trigger second trigger button 262. The second hard push plates 242 are a plurality of, and the second hard push plates 242 are arranged at intervals. The second hard push plate 242 can increase the force of the sealing air bag 240 on the second trigger button 262, so that the sealing air bag 240 can accurately press the second trigger button 262.
In order to further reduce the possibility of harmful substance leakage, the exhaust treatment module 200 further includes: a driver 271, a control ring 272 and a collection cage 273. The control ring 272 is slidably sleeved on the air feeding pipe 210 and driven by the driver 271, and the collecting cover 273 is annularly arranged on the air feeding pipe 210 and fixedly connected to one side of the control ring 272 close to the activated carbon adsorption box 220. The collecting hood 273 is connected with an inlet pipe 274 and an outlet pipe 275.
When the activated carbon adsorption tank 220 is fitted between the air supply pipe 210 and the exhaust pipe 230, the driver 271 can drive the control ring 272 to move, so that the collection cover 273 abuts against the end surface of the activated carbon adsorption tank 220, thereby covering and closing the fitting portion of the air supply pipe 210 and the communication port 221.
In this state, by blowing clean air through the inlet pipe 274 and drawing the air out through the outlet pipe 275, the harmful substances that may overflow can be recollected to avoid being dissipated into the environment.
It should be noted that the exhaust pipe 230 and the air feeding pipe 210 are designed symmetrically, and the structure of the exhaust pipe 230 is not described herein again, and reference may be made to the related content of the air feeding pipe 210.
