Detailed Description
The utility model discloses the principle lies in, and clean shed structure of system optimization design compromises the actual need of clean canopy basic performance and simple and easy swift installation.
The utility model is suitable for an area that local purification rank required height in the workshop, like the pipelining region.
The utility model discloses a: the device comprises a frame 1, a sealing plate 2, a fan filter unit 3, an anti-static vertical curtain 4 and a truss 8.
The present invention will be further explained with reference to the drawings and examples.
Example 1: as shown in the attached drawings 1, 2 and 3, a group of mutually parallel trusses 8 are installed at the top of a frame 1 of the three-dimensional van-type structure, a fan filter unit 3 is installed on the upper side of the top of the frame 1 between two adjacent trusses 8, and a sealing plate 2 is laid at the top of the frame 1.
In the foregoing, a group of four mutually parallel trusses 8 are installed at the top of the frame 1, and three fan filter units 3 are uniformly installed on the upper side of the top of the frame 1 between two adjacent trusses 8.
In the above, the anti-static drapes 4 are laid on the outer wall elevation of the frame 1.
In the foregoing, tempered glass is laid on the facade of the outer wall of the frame 1.
