There is a dust collection box at the bottom of the bottom plate opening area, which is made of a three-millimeter steel plate and has a size of 1000mm*2000mm. It has a handle for convenient pulling and cleaning of internal debris. The three inner walls and the top of the room are covered with 50mm thick sound insulation cotton, and the sound insulation cotton is decorated with steel scales and porous plates. There are two indoor lightings, one mechanical ventilation on the top, and an exhaust pipe interface under the bottom plate. The opening on the bottom plate is used to circulate the gas in the room, and metal debris can also fall into the drawer below through the low plate opening. A pleated curtain is used at the entrance of the room to facilitate objects to enter and exit the workshop. There are 4 hanging codes on the top of the outdoor room for convenient transfer and use.

[0014] Noise control is mainly achieved through isolation of sound-absorbing cotton on the four walls of the workshop, the main component of which is ceramic fiber cotton. The exhaust fan ventilates the room gas from the bottom through the pipe, which is filtered through the air filter (the filter material is made of polyester fiber) and finally discharged into the atmosphere.
