Detailed description of the invention
Below in conjunction with Figure of description, the utility model embodiment is described in further detail.
For achieving the above object and adopt technical solution be such: a kind of safety cabinet gas discharging Rose Box provided, as shown in Figure 1-2, comprise the first casing 1 being provided with air inlet N1, be provided with second casing 2 of exhaust outlet N2, be arranged on the active carbon filter 3 in the first casing 1 and blower fan 5, and be arranged on the air-discharge silencer 6 of the second casing 2, second casing 2 is arranged on the top of the first casing 1 and is interconnected, as shown in Figure 3-4, the filtering module of active carbon filter 3 is made up of polylith filtrating chip, V-shaped structure between adjacent head chip, this filtrating chip is made up of high adsorption rate active carbon, modular organization, be convenient to dismounting, it is convenient to replace, blower fan 5 is positioned at immediately below the second casing 2, and the air outlet of blower fan 5 is towards the air-discharge silencer 6 in the second casing 2.
The casing of safety cabinet gas discharging Rose Box is divided into the first casing 1 and the second casing 2, all adopt heat insulation, antidetonation, noise reduction, water resistance are effective, and the color steel clamp core flame retardant type storehouse of surface electrostatic painting easily plate material of drawing materials is made.Internal fan 5 in first casing 1 adopts explosion-proof type blower fan, and be arranged in damping base 4, simultaneously blower fan adopts explosion-proof type electrical wiring to be connected to the anti-explosion terminal box 8 on the first casing 1 and the Boiler pressure control case on safety cabinet 12 successively, can effectively prevent chemical gas and microorganism on the impact of electric components and circuit; Be arranged on Boiler pressure control case on safety cabinet control the air force of explosion-proof fan by Long-distance Control Rose Box thus controlled filter case high-volume, with the different amount of exchanging for required during applicable different experiments.
In second casing 2, air-discharge silencer 6 is set, between the end face that air-discharge silencer 6 tilts to be fixed on the second casing 2 and relative with exhaust outlet N2 side, and is positioned at directly over blower fan 5 air outlet; Air-discharge silencer is the design of honeycomb tabular as shown in Figure 5; This air-discharge silencer can by noise reduction during blower fan air-out to 50dB (A) below, prevent exhaust noise to the interference of other department and agencies around laboratory effectively.The horizontal air exhausting structure of side employing that exhaust outlet N2 is arranged on the second casing 2 is to prevent the impact of surface-mounted casing when air draft on other floors of top, avoiding unnecessary chimney structure; Exhaust outlet N2 adopts shutter 11 structure to regulate the pattern of wind direction simultaneously, can discharge the air conforming with emission request in the mode of air draft near the ground.
