Abstract
The utility model relates to a negative pressure clean transferring window. The negative pressure clean transferring window comprises an outer box, wherein a transferring window door which can be opened, closed and sealed is respectively arranged at each of two sides of the outer box, an inner box the two ends of which are respectively communicated with the transferring window doors is also arranged inside the outer box, a diffusing plate and a laminar flow cover which are communicated with the interior of the inner box are arranged at the top of the inner box, and a centrifugal fan and a high efficiency filter are arranged on the laminar flow cover; an internal circulation space is defined by the interior of the laminar flow cover, the interior of the inner box and a space between the outer box and the inner box; an ultraviolet lamp is also arranged in the internal circulation space. The negative pressure clean transferring window has the advantages that the internal circulation space with a high-efficiency filtration and ultraviolet sterilization device is constructed, so that a purifying process is completed by virtue of sterilization and disinfection of the internal circulation space in a process of transferring an article from one space to another space, and thus cross contamination is avoided.
Description
Technical field:
This utility model belongs to pharmaceutical industries equipment technical field, refers in particular to the clean pass-through box of a kind of negative pressure.
Background technology:
Apparatus, device and medicine product itself used in drug production process has very high requirement to the cleaning of working environment, comprises transfer, the transmittance process of article, all needs to avoid as much as possible to pollute.And at present, in the transmittance process for article between clean area and clean area or non-clean area, or there is larger pollution risk, bring larger potential safety hazard to pharmaceutical production.
Utility model content:
The purpose of this utility model is to overcome the weak point of existing equipment, provides a kind of negative pressure clean pass-through box.
The technical scheme that this utility model is realized its object employing is: the clean pass-through box of a kind of negative pressure, this pass-through box comprises an outer container, these outer container both sides are respectively equipped with can folding and the transmission window of sealing, also be provided with in described outer container inside the interior case that two ends communicate respectively at described transmission window, the top of this interior case is provided with the diffuser plate and the laminar flow hood that communicate with interior case inside, and laminar flow hood is provided with centrifugal blower, high efficiency particulate air filter; Interval between described laminar flow hood inside, interior case inside and outer container and interior case forms an internal recycle space; In described internal recycle space, uviol lamp is also installed.
Between two described transmission windows, be connected with electronic interlock.
On described outer container, be also provided with differential manometer.
This utility model is by building an internal recycle space with high efficiency filter and ultraviolet sterilization device, make article being passed to another steric course from a space, through the sterilizing in this internal recycle space, complete purification process, thereby avoid cross-contamination.
Brief description of the drawings:
Fig. 1, Fig. 2 are that master of the present utility model looks and side-looking structural representation.
Detailed description of the invention:
Below in conjunction with specific embodiments and the drawings, this utility model is further illustrated.
As Fig. 1, shown in Fig. 2, the clean pass-through box of a kind of negative pressure described in the utility model, this pass-through box comprises an outer container 1, these outer container 1 both sides are respectively equipped with can folding and the transmission window 11 of sealing, also be provided with in described outer container 1 inside the interior case 2 that two ends communicate respectively at described transmission window 11, the top of this interior case 2 is provided with the diffuser plate 3 and the laminar flow hood 4 that communicate with interior case 2 inside, laminar flow hood 4 is provided with centrifugal blower 41, high efficiency particulate air filter 42, centrifugal blower 41 is arranged on laminar flow hood 4 tops, communicate with the interior space of outer container 1, 42 of high efficiency particulate air filters are arranged on laminar flow hood 4 bottoms, communicate with diffuser plate 3 and the interior space of interior case 2, interval between described laminar flow hood 4 inside, interior case 2 inside and outer container 1 and interior case 2 forms an internal recycle space 100, filter dust by high efficiency particulate air filter 42, constantly keep the cleaning in internal recycle space 100, simultaneously, in described internal recycle space 100, uviol lamp 5 is also installed, the present embodiment medium ultraviolet lamp 5 is arranged on the lower position of diffuser plate 3, uviol lamp 5 has the effect of sterilizing, thereby coordinate air in it or article are carried out to sterilizing processing with high efficiency particulate air filter 42, make air, article keep clean.
Between two described transmission windows 11, be connected with electronic interlock 12, under the state of opening at Yishanmen, another Yishanmen must be in closed condition, the air of avoiding the two simultaneously to open and to make non-clean area directly enters clean area through pass-through box, avoids causing while carelessness because of personnel two accidental pollution events of simultaneously opening by electronic interlock 12.
On described outer container 1, be also provided with differential manometer 13, the pressure reduction of case 2 inside and the ruuning situation of high efficiency particulate air filter 42 in monitoring.
In the time that needs transmit article, open a fan and transmit window, another Yishanmen, in closed condition, says that article are placed in interior case, then shut transmission window, open uviol lamp 5 and centrifugal blower 42 by manual or automaton, make the internal recycle space 100 in pass-through box start internal recycle operation, within a certain period of time article are carried out to sterilizing, complete after purification, open again the another Yishanmen communicating with another space, take out article; Shut behind the door, uviol lamp 5 and centrifugal blower 42 can extinguish manually or automatically again.
This utility model is by building an internal recycle space with high efficiency filter and ultraviolet sterilization device, make article being passed to another steric course from a space, through the sterilizing in this internal recycle space, complete purification process, thereby avoid cross-contamination.
