Summary of the invention
The utility model is in order to overcome the shortcoming of above-mentioned technical problem, provide that the outer gas of a kind of safety cabinet enters around the cabinet outer wall bottom side four sides negative-pressure type Biohazard Safety Equipment.
Four sides of the present utility model negative-pressure type Biohazard Safety Equipment, comprised the protection and the safety cabinet outer wall of sealing function, be provided with the workspace of workbench and be arranged at blower fan system in the safety cabinet outer wall, its special feature is: described safety cabinet outer wall bottom side outer wall be provided with the air intake grid all around; Described blower fan system comprises blower fan, the plenum chamber that is connected with the air outlet of blower fan and the air outlet that is connected with plenum chamber, be provided with exhaust-air filter between described plenum chamber and the air outlet, described plenum chamber communicate with the workspace and plenum chamber and workspace between be provided with the powered air-purifying device.The safety cabinet outer wall plays support, protection and buffer action, except air intake grid and air outlet, does not communicate with the outside in the safety cabinet; The workspace is provided with workbench, so that place corresponding trial target; Blower fan system is arranged in the safety cabinet outer wall, has not only realized the circulation of corresponding air-flow, has also reached to avoid the purpose polluted.
Four sides of the present utility model negative-pressure type Biohazard Safety Equipment, the air intake grid that is arranged on the safety cabinet outer wall is respectively front side air intake grid, rear side air intake grid, left side air intake grid and right side air intake grid.By around the safety cabinet outer wall, the air intake grid being set all, realized the purpose that all around enter of outer gas stream by safety cabinet, effectively avoided entering the cross-infection that is produced by the two sides in the past.
Four sides of the present utility model negative-pressure type Biohazard Safety Equipment is provided with plane deflector and arc deflector in the described plenum chamber, described plane deflector is arranged on the air outlet place of blower fan; Described arc deflector is fixedly installed on the inwall of plenum chamber, and the end of plane deflector is pointed in the inboard of arc deflector.The plane deflector can be realized shunting action, and a part of gas is flowed out through air outlet, and remaining gas enters in the plenum chamber, and arc deflector makes air-flow more unimpeded, also helps reducing noise.
Four sides of the present utility model negative-pressure type Biohazard Safety Equipment also is set with guidance panel on the described safety cabinet outer wall, and this guidance panel is provided with shift knob and operation push-button.Relevant shift knob and operation push-button are arranged on the guidance panel, are convenient to operating personnel's use.
The beneficial effects of the utility model are: the utility model is by all being provided with the air intake grid around the safety cabinet outer wall, and in the safety cabinet outer wall, blower fan system is set, realized the purpose of air inlet around Biohazard Safety Equipment, make safety cabinet all produce negative pressure all around, the infection morbidity of laboratory worker has been avoided in the air cross-infection of effectively having avoided both sides air inlet in the past to be caused; The utility model also can be provided with plane deflector and arc deflector in plenum chamber, promptly realized the shunting of gas, has also reduced the noise that air-flow produced effectively.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Fig. 2 is a left TV structure schematic diagram of the present utility model
Among the figure: 1 safety cabinet outer wall, 2 workspaces, 3 blower fans, 4 powered air-purifying devices, 5 exhaust-air filters, 6 front side air intake grids, 7 left side air intake grids, 8 right side air intake grids, 9 rear side air intake grids, 10 plane deflectors, 11 arc deflectors, 12 air outlets, 13 plenum chambers, 14 guidance panels, 15 air flues.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
As depicted in figs. 1 and 2, provided the structural scheme of mechanism of four sides of the present utility model negative-pressure type Biohazard Safety Equipment respectively, it comprises safety cabinet outer wall 1, workspace 2, blower fan 3, powered air-purifying device 4, exhaust-air filter 5, plane deflector 10, arc deflector 11, air outlet 12, plenum chamber 13, guidance panel 14; Safety cabinet outer wall 1 plays and supports and protective effect.Offer front side air intake grid 6, left side air intake grid 7, right side air intake grid 8, rear side air intake grid 9 respectively on four limits of safety cabinet outer wall 1 bottom surface, the indoor gas of safety cabinet outer wall 1 outside can enter the inside of safety cabinet outer wall 1 by these four air intake grids.Workspace 2 is provided with workbench, uses for the staff, and on the corresponding safety cabinet outer wall 1 of workbench combining glass can be set, and helps staff's use more.Guidance panel 14 fixes with safety cabinet outer wall 1, and guidance panel is provided with and is used for shift knob and operation push-button that Biohazard Safety Equipment is controlled, uses with convenient.
