FFU is english abbreviation, and full name is Fan Filter Units, and the Chinese meaning is " blower fan filter unit (unit) ".Namely blower fan and filter (high efficiency particulate air filter (HEPA) or super high efficient filter (ULPA)) are combined the terminal cleaning equipment that formation self provides power.It exactly is a kind of self-powered, modular end air flow device with filter efficacy.Blower fan filters from the FFU top with air intake and through HEPA, and the clean air after the filtration is evenly sent with the wind speed of 0.45m/s ± 20% at whole outlet air surface.
Yet, its blower fan that adopts of existing FFU and terminal box are common blower fan and common terminal box respectively, these common blower fans and common terminal box produce electrical spark easily in the process of work, when these FFU are applied to such as medical cleanroom, laboratory cleanroom, Combustible Place cleanroom, the electrical spark that produces usually causes these cleanrooms to blast easily, thereby exists very important potential safety hazard.
The model utility content
In view of this, the utility model is for the disappearance of prior art existence, its main purpose provides a kind of outer explosion-proof FFU of brush DC that turns, and it can effectively solve existing FFU and adopt common blower fan and common terminal box to produce easily the problem that electrical spark causes the potential safety hazard of cleanroom's existence blast.
For achieving the above object, the utility model adopts following technological scheme:
Turn the explosion-proof FFU of brush DC outside a kind of, include casing, main filter screen, explosion-proof outer rotor blower fan and anti-explosion terminal box; Have the air channel in this casing, the top of casing arranges the intake grill that is communicated with the air channel, and the bottom of casing is provided with the exhaust outlet that is communicated with the air channel; This main filter screen is arranged at the bottom of casing and covers this exhaust outlet; This explosion-proof outer rotor blower fan is arranged in the intake grill; This anti-explosion terminal box is arranged at the outer surface of casing and connects explosion-proof outer rotor blower fan.
As a kind of preferred version, the top of described casing is provided with the suction port net, and this suction port net covers this intake grill.
As a kind of preferred version, described anti-explosion terminal box is arranged at the top of casing and is positioned at by the side of suction port net.
As a kind of preferred version, described main filter screen is the glass fibre material.
As a kind of preferred version, the both sides, top of described casing are provided with the leader.
The utility model compared with prior art has obvious advantage and beneficial effect, particularly, and as shown from the above technical solution:
One, by adopting explosion-proof outer rotor blower fan and anti-explosion terminal box, the common blower fan and the common terminal box that have replaced tradition, the utility model can not produce electrical spark in the process of work operation, effectively prevented the generation of explosion phenomenon, stopped potential safety hazard, Safety performance is better, and air output is larger, has the usability of superelevation.
Two, by adopting explosion-proof outer rotor blower fan, utilize explosion-proof outer rotor blower fan volume little, so that the air channel is more without hindrance, the FFU performance is better, utilize explosion-proof outer rotor blower fan lightweight, to reduce the weight of whole group of FFU, be easier to carrying and installation, utilize simultaneously the high rigidity of explosion-proof outer rotor blower fan, so that the running of complete machine vibration is less.
For more clearly setting forth structure characteristic of the present utility model and effect, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment.
