Abstract
The utility model discloses a biological safety cabinet with a uniform and stable air speed. The biological safety cabinet comprises a table board, wherein a bottom air duct is arranged below the table board; the table board is provided with a groove; and an air inlet window which is communicated with the bottom air duct is arranged in the groove of the table board. The air inlet window is arranged in the groove on the table board, so that the distance between an arm and the air inlet window during a biological experiment is increased, and the influence of the arm on the air speed of the air inlet window is overcome. Therefore, a hand rest frame is not required, and the cost is reduced; and tests show that the uniformity of pressing air speed and the stability of air speed of a suction port of the safety cabinet are greatly improved in comparison with the safety cabinet using flat plate type air inlet window. Through the safety cabinet, the resistance for air to enter the suction port of the safety cabinet is reduced, so that the air speed of the suction port is more stable and uniform, the safety of operation personnel and samples is guaranteed, cross infection is avoided, and the noise of the safety cabinet is controlled at the lowest level during running.
Description
Technical field
The utility model relates to a kind of Biohazard Safety Equipment, particularly a kind of biologic test safety cabinet.
Background technology
Safety cabinet requires to enter into the cabinet gas inside and wants most of circulation, and fraction is discharged to indoor or outdoors.After fan starting, the inner negative pressure that forms of safety cabinet, wind air-inlet window in the past enters into cabinet inside, by the bottom ventilating duct, air channel, the left and right sides, the rear side ventilating duct, enter into the blower fan inlet scoop, blower fan promotes distribution of air flow and gives filter up and down then, the air-flow of filter directly is discharged to indoor or outdoors on the process, the process air-flow of filter down enters the operating space is drawn into safety cabinet by the wind inlet on operating space inner surface and the deck plate air channel, bottom, the process that one enters into next repetitive cycling is converged into the air-flow of wind inlet in left and right sides air channel and rear side air channel.In this process, must guarantee to press down the uniformity of wind speed and the wind speed of suction inlet, to guarantee that also the air-tightness of the connection of filter up and down and the air quantity that filter divided up and down keep certain proportion.
The flat air intake pattern of the general employing of air-inlet window before the conventional security cabinet, deck plate is dull and stereotyped, be provided with a plurality of wind inlets that communicate with air intake passage below the deck plate on the flat board, a plurality of wind inlets form air-inlet window, when carrying out Bioexperiment, arm is placed on above the air-inlet window or is nearer from air inlet, will influence incoming air area, air inlet wind speed shakiness before causing; Install additional and put arm device, can reduce preceding air inlet Influences on Wind Velocity, but cost can increase; Because the working environment of safety cabinet is more special, under different situations, need to adjust different wind speed, all difficult adjustment the when under conventional environment, guaranteeing the uniformity, wind speed of decline wind speed and suction inlet wind speed, when changing (for example in the negative pressure laboratory) at the safety cabinet working environment, bad especially adjustment.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of wind speed uniform and stable Biohazard Safety Equipment, when making work, operator's arm can not stop air-inlet window and influence air intake.
For addressing the above problem, the utility model comprises deck plate, and the deck plate below is provided with air channel, the end, and deck plate is provided with groove, is provided with the air-inlet window that communicates with air channel, the end in the groove of deck plate.
For the ease of processing, described groove is a V-shaped groove.
For the ease of cleaning and maintenance, the bottom land of described V-type groove is a circular arc chamfering.
In order to improve the uniformity of air intake, be densely covered with wind inlet on the whole cell body of described V-shaped groove, V-shaped groove and on wind inlet form described air-inlet window.
The beneficial effects of the utility model: the air-inlet window of the utility model setting is located in the groove on the deck plate, increases the distance of arm and air-inlet window when carrying out Bioexperiment, and the solution arm is to the air-inlet window Influences on Wind Velocity.Therefore, do not need hand support, reduced cost, this kind safety cabinet presses down the uniformity of wind speed and the stability of suction inlet wind speed through test, compares all with the safety cabinet that adopts flat air-inlet window to improve a lot.The utility model has reduced the resistance that wind enters the safety cabinet suction inlet, makes the suction inlet wind speed stable more and evenly, guarantees the security of operating personnel and sample, avoids cross-infection; Also make the noise control of safety cabinet in running at floor level.
