As everyone knows; between the weighing in pharmaceutical factory or between pulverizing; dust from flying is comparatively serious; easily cause the cross pollution of medicinal powder and endanger the healthy of operating personnel; for solving this problem, normally between weighing or in pulverizing, laminar flow hood is set, effectively to prevent flying upward arbitrarily of dust; thus the cross pollution that efficiently avoid between medicinal powder, also protective effect is served to operating personnel.And existing laminar flow hood, usually too many requirement is not done to the illuminator of this equipment and mode of operation, basic requirement can be met, the illumination of its inside is that mode that is changeless, that control blower fan is single, and be also not suitable for working long hours, this is because the circulated air in equipment upgrades slow, the duration of runs is time long, in equipment, the temperature of wind can promote to some extent, and then can have influence on the performance of thermal sensitivity medicine in laminar flow hood, and this is that pharmaceutical factory institute is unallowed.
Utility model content
The purpose of this utility model is to provide a kind of laminar flow hood; this laminar flow hood can be pharmaceutical factory weigh between, pulverize between etc. dust many and room that is that easily fly upward provides a clean environment; thus effectively prevent the cross pollution between medicine and protect operating personnel; and according to actual service condition, the utility model mainly carries out Curve guide impeller with operating aspect to equipment from energy-conservation.
For solving the problems of the technologies described above, the utility model is realized by the following technical programs:
Described a kind of laminar flow hood, comprise cover body, the side of described cover body is return side, the sidewall of cover body surrounds the workspace of hollow, the top of cover body is outlet air surface, the cover body that it is characterized in that return side is provided with just medium effeciency filter, the top of described return side is disposed with centrifugal blower and high efficiency particulate air filter, the cover body of outlet air surface is provided with panel light and current-sharing film, the cover body inwall being positioned at workspace is provided with light adjusting system, refrigeration system, differential pressure indicator and return air cover plate, and described return air cover plate is positioned at the lower end of cover body.
Described a kind of laminar flow hood, is characterized in that light adjusting system comprises light-control knob, and described light-control knob is connected with panel light electric wire.
Described a kind of laminar flow hood, is characterized in that workspace cover body inwall is also provided with frequency-changer operation panel and action button.
Described a kind of laminar flow hood, is characterized in that described outlet air surface is provided with volume damper away from the cover body of return side.
Described a kind of laminar flow hood, is characterized in that described just medium effeciency filter is spirally connected and is arranged on the lower end of return side near the side of workspace, be communicated with return air cover plate.
Compared with prior art, the utility model has the advantage of, realized the real-time adjustment of illuminator by the light-control knob arranged, be convenient to save power supply; By frequency-changer operation panel and the action button of setting, the automatic startup of blower fan can be realized and manually boot, being convenient to regulate in real time the frequency of blower fan, thus the demand under meeting different situations, make the mode of operation of equipment present diversity.By the refrigeration system arranged, make the temperature of circulated air can obtain certain control, thus expand the practicality of equipment.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, and provides detailed description of the invention.
As Figure 1-3, a kind of laminar flow hood of the utility model, comprise cover body, the side of cover body is return side 1, the sidewall of cover body surrounds the workspace 2 of hollow, the top of cover body is outlet air surface 3, the cover body of return side 1 is provided with just medium effeciency filter 4, the top of return side 1 is disposed with centrifugal blower 5 and high efficiency particulate air filter 6, the cover body of outlet air surface 3 is provided with panel light 7, current-sharing film 8, volume damper 15, the cover body inwall being positioned at workspace 2 is provided with light adjusting system, refrigeration system 9, differential pressure indicator 10 and return air cover plate 11, return air cover plate 11 is positioned at the lower end of cover body, this return air cover plate 11 is communicated with first medium effeciency filter 4, wherein light adjusting system comprises the light-control knob 12 linked with panel light 7 electric wire, workspace cover body inwall is also provided with frequency-changer operation panel 13 and action button 14, the differential pressure conditions observing tertiary filter is in time convenient in the setting of differential pressure indicator 10.
As shown in Figure 2, the utility model establishes the action button 14 that exposes and display element to have frequency-changer operation panel 13, differential pressure indicator 10, light-control knob 12, action button 14, the differential pressure conditions of tertiary filter can be seen through differential pressure indicator 10, can be regulated in real time the brightness of device interior by light-control knob 12, automatic and manual operation real-time operation of the present utility model can be realized in conjunction with frequency-changer operation panel 13, action button 14.And by refrigeration system 9, the temperature of the circulated air in equipment can be made to be controlled preferably.
Utility model works process is, worked by centrifugal blower 5, distinguished and admirable to return side 1 by equipment, wind is discharged outside laminar flow hood in an outlet air surface 3 place part by volume damper 15, a part in flowing to laminar flow hood workspace 2 place vertically downward by current-sharing film 8, thus is impelled inside and outside equipment and is presented certain negative pressure.At workspace 2 place, dust can be blown to return air cover plate 11 along with wind direction according to the flow direction shown in Fig. 3, enter just medium effeciency filter 4 subsequently, tiny dust may flow to high efficiency particulate air filter 6 further after first medium effeciency filter 4, dust in such equipment is after tertiary filter, until during outlet air surface 3 place, the dust comprised in circulated air is just extremely few, thus effectively solves the series of problems that in weighing or crushing process, dust from flying brings.
Illumination system layout, from Energy Angle, is become real-time, tunable, can save certain power supply better by the utility model.Operationally, equipment de-sign, from control mode, becomes not only automatically to start blower fan but also can manually regulate in real time the frequency of blower fan by the utility model, thus the demand under meeting different situations, make the mode of operation of equipment present diversity.And when equipment is worked long hours, in equipment, add refrigeration system, make the temperature of circulated air can obtain certain control, thus expand the practicality of equipment.
Specific embodiment described is herein only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
