[0023] See also Figures 1 to 5 The utility model provides a technical solution: a regenerable VOCS exhaust gas absorption device, comprising a box body 1, honeycomb activated carbon 2, an intake pipe 3 and an exhaust pipe 4. Honeycomb activated carbon 2 is installed inside the box body 1, one end of the box body 1 is connected to the intake pipe 3, and the other end of the box body 1 is connected to the exhaust pipe 4.

[0024] A positioning plate 5 is provided on the back of the honeycomb activated carbon 2, one side of the positioning plate 5 is connected to the first connecting block 6, the other side of the positioning plate 5 is connected to the second connecting block 7, the bottom of the second connecting block 7 is connected to the connecting column 8, the bottom of the connecting column 8 is connected to the mounting shaft 9, the internal movably connected to the mounting shaft 9 is connected to the pulley 10, the inner wall of the box body 1 near the pulley 10 is installed with a slide rail 11, the bottom of the first connecting block 6 is connected to the L-shaped pull rod 12, the surface of the box body 1 near the L-shaped pull rod 12 is welded with a guide block 13, a sliding structure is formed between the L-shaped pull rod 12 and the guide block 13, and the first connecting block 6 and the second connecting block 7 have the same shape.

[0025] Example 2

[0026] On the basis of embodiment 1, in order to realize the rapid replacement of honeycomb activated carbon 2, after the box door is opened, the L-shaped pull rod 12 can be pulled. When the L-shaped pull rod 12 moves, it can slide through the guide block 13, and when the L-shaped pull rod 12 slides, it can drive the first connecting block 6 to move. When the first connecting block 6 moves, it can drive the positioning plate 5 to move. When the positioning plate 5 moves, it can drive the second connecting block 7 to move. When the second connecting block 7 moves, it can drive the connecting column 8 to move. When the connecting column 8 moves, it can drive the installation shaft 9 to move. When the installation shaft 9 moves, it can drive the pulley 10 on the slide rail 11 The interior rolls, and while the positioning plate 5 moves, all the honeycomb activated carbon 2 inside the box body 1 can be driven to move outward. When the L-shaped pull rod 12 slides to the maximum distance, all the honeycomb activated carbon 2 inside the box body 1 can be pulled out. At this time, all the honeycomb activated carbon 2 inside the box body 1 can be taken out from the positioning plate 5 at the same time, and replaced with a new honeycomb activated carbon 2. When the new honeycomb activated carbon 2 is installed, the L-shaped pull rod 12 can be pushed, so that all the new honeycomb activated carbon 2 inside the positioning plate 5 can be pushed into the box body 1 at one time. By taking out and replacing at one time, the efficiency of replacing the honeycomb activated carbon 2 can be improved.

[0027] A fixing block 14 is welded to the inner wall of the box body 1 near the air intake pipe 3, and a groove 15 is opened through the inside of the fixing block 14. The internal thread of the fixing block 14 is connected to a knob 16, and the end of the knob 16 is connected to a rubber protrusion 17. A mounting plate 18 is provided between the two grooves 15, and a dust filter 19 is installed inside the mounting plate 18. A sliding structure is formed between the mounting plate 18 and the fixing block 14 through the groove 15.

[0028] Example 3

[0029] On the basis of Example 2, in order to filter the dust particles in the VOCS exhaust, the mounting plate 18 can be pushed. When the mounting plate 18 moves, the dust filter 19 can be driven to move. When the mounting plate 18 moves between the two sets of grooves 15, the mounting plate 18 can slide into the inside of the fixed block 14. When the mounting plate 18 is completely moved into the inside of the box body 1, the two sets of knobs 16 can be rotated. When the knobs 16 are rotated, they can slide with the fixed block 14. When the knobs 16 slide, the rubber protrusions 17 can be driven to move. When the rubber protrusions 17 move, they can squeeze and fix the surface of the mounting plate 18. At this time, the rubber protrusions 17 produce extrusion deformation, thereby installing the mounting plate 18 inside the box body 1. The rubber protrusions 17 can prevent the mounting plate 18 from shaking. When the VOCS exhaust enters the inside of the box body 1 through the intake pipe 3, the dust particles in the VOCS exhaust can be filtered through the dust filter 19 to prevent the dust particles from adhering to the surface of the honeycomb activated carbon 2 and affecting the normal use of the honeycomb activated carbon 2.

[0030] In actual use, after the box door is opened, the L-shaped pull rod 12 can be pulled. When the installation shaft 9 moves, the pulley 10 can be driven to roll inside the slide rail 11, and while the positioning plate 5 moves, all the honeycomb activated carbon 2 inside the box body 1 can be driven to move outward. When the L-shaped pull rod 12 slides to the maximum distance, all the honeycomb activated carbon 2 inside the box body 1 can be pulled out. At this time, all the honeycomb activated carbon 2 inside the box body 1 can be taken out from the positioning plate 5 at the same time, and replaced with a new honeycomb activated carbon 2. When the new honeycomb activated carbon 2 is installed, the L-shaped pull rod 12 can be pushed, so that all the new honeycomb activated carbon 2 inside the positioning plate 5 can be pushed into the box body 1 at one time. By taking out and replacing at one time, the efficiency of replacing the honeycomb activated carbon 2 can be improved. When the VOCS exhaust gas enters the box body 1 through the intake pipe 3, the dust particles in the VOCS exhaust gas can be filtered through the dust filter 19 to prevent the dust particles from adhering to the surface of the honeycomb activated carbon 2 and affecting the normal use of the honeycomb activated carbon 2.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
