Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, in particular to an environmental protection equipment applied to a polyoxymethylene production workshop. Background Art

[0002] Activated carbon boxes can be used in polyformaldehyde production workshops. The activated carbon adsorption box can effectively adsorb these harmful gases through its high adsorption performance, thereby achieving the purpose of purifying the air.

The activated carbon body 603 can be adjusted to facilitate quick replacement, thereby reducing the difficulty of replacing the activated carbon body 603. When the placement frame 602 at different positions needs to be replaced, the first motor 309 is started, and the output shaft of the first motor 309 rotates to drive the first screw rod 308 to rotate. When the first screw rod 308 rotates, the thread drives the first slide 303 to slide on the guide rod 302. The setting of the guide rod 302 makes the first slide 303 slide more smoothly. The first slide 303 slides left and right and cooperates with the slide frame 401 to slide up and down, so that the placement frames 602 at different positions can be disassembled easily.
