In the back side body of described clean medicament preparation cabinet air cleaning system is set, the upper end of described back side body is provided with a blower fan, the air inlet connection of blower fan is provided with a return air channel, the exhaust outlet connection of blower fan is provided with an air-supply passage, the other end of described return air channel is provided with vent, and the other end connection of described air-supply passage is provided with return air hole.
The middle part fixed in position one preparation workbench of described clean room, distribute on the housing wall on described this preparation workbench top and be provided with the vent of grid shape, distributing on the housing wall of described this preparation workbench bottom is provided with the return air hole of grid shape, and described vent and return air hole all are arranged on the rear side housing wall of clean medicament preparation cabinet formation clean room.
Be provided with high efficiency particulate air filter between the exhaust outlet of described blower fan and air-supply passage and between the air inlet of blower fan and return air channel, described air-supply passage top near exhaust outlet is provided with an air exhaust passage, and this air exhaust passage place is provided with a medium effeciency filter.
Described return air channel top near air inlet is provided with an outside air inlet, and this air inlet place, outside is provided with a rough filter.
The cabinet wall of the clean preparation area sidepiece of described sealing is provided with the interlocking-type that is used for exterior and transmits window, and described interlocking-type transmits left and right sides either side or the both sides that window is arranged on the clean preparation of sealing zone.
The sidepiece of the clean preparation area of described sealing is provided with the medicament storage cabinet, and described medicament storage cabinet transmits window with sealing clean medicament preparation area by interlocking-type and is communicated with.
Described clean medicament preparation cabinet also comprises the medicament storage cabinet that is positioned at the setting of the clean room left and right sides and is used to control the electric control switch of the electric equipment of this clean medicament preparation cabinet.
Be provided with illuminating lamp and uviol lamp in the clean preparation area of described sealing, be provided with ozonator in the circulation canal of described air cleaning system.
This clean medicament preparation cabinet mainly is made up of clean preparation area of sealing and air cleaning system, this air cleaning system adopts the blower fan of single setting, and its energy consumption is low, and the air circulation that can realize sealing in the clean preparation area purifies, improve clean-up effect, and reduced the loss of filter.This air cleaning system is by the return air channel of the air inlet connection of this blower fan, blower fan, and the air-supply passage that the exhaust outlet of blower fan connects forms and the air circulation of sealing clean preparation area, and the filter of different filter efficiencies is set reasonably at the different parts of this cyclic process, just can realize low energy consumption and air circulation utilization efficiently, to recycle through the air of a high efficiency filter, improved the air quality of sealing in the clean preparation area effectively, and amount of air circulation is reduced.The air-supply of single blower fan makes in the clean preparation area of sealing and forms malleation,, seal in the clean preparation area with regard to the air admission outside having avoided like this and pollute.
This seals clean preparation area is made up of carbon steel and stainless clean medicament preparation cabinet housing and hermatic door, and the sealing door preferably adopts the plug-type arc hermatic door of outside protrusion, both can effectively increase the usage space of the clean preparation area of sealing.The preparation workbench that seals in the clean preparation area is positioned at medium position, the vent of its upper portion side wall can suck return air channel with the gas that contains the drug volatilization thing timely, and filter through high efficiency particulate air filter, recover the high cleaning and the harmless state of this portion gas, this gas enters air-supply passage through the exhaust outlet of blower fan then, after high efficiency particulate air filter in air-supply passage filters once more, enter once more in the clean preparation area of sealing by the return air hole of preparing the workbench lower sides with high clean state, finish air circulation.In order to improve the safety of recyclegas, can in air cleaning system, offer an air exhaust passage and outside air inlet, the gas of realizing small part exchanges with extraneous, can be located at a medium effeciency filter at this place, exhaust passage, realize innoxious qualified discharge, at this air inlet place, outside one rough filter can be set, make-up gas is carried out the pre-filtering cleaning.High efficiency particulate air filter used in the present invention can be the filter to microgranule interception rate 〉=99.99% of diameter 〉=0.3 μ m, and medium effeciency filter and poor efficiency are crossed the diameter of effective interception microgranule of device and increased gradually.
This utility model adopts the air cleaning system of small-power blower fan, by recycling of air, effectively reduced taking up room of air cleaning system, and it is capable of reducing energy consumption, improve the air cleaning quality of the clean preparation area of sealing, and, avoid the pollution of outside unholiness air, the health clean level that sound assurance is made up a prescription and the safety of making up a prescription at the clean preparation area formation of sealing air positive pressure.
