Description
Technical field
The utility model relates to a kind of Biohazard Safety Equipment.
Background technology
At present; a kind of apparatus often used when Biohazard Safety Equipment is multi-medicament preparation; it forces air draft by ventilation unit; the harmful substance diffused to when making up a prescription in air can be forced to discharge; or when operating primary culture, bacterium diseased plant and diagnostic sample etc. and there is infective experiment material; be used for protecting operator, laboratory environment and experiment material, make it avoid being exposed to issuable infectious aerosol and spatters in aforesaid operations process.
Gas flow optimized is the core technology of Biohazard Safety Equipment.As a qualified Biohazard Safety Equipment, except air velocity needs to reach requirement, air-flow also needs to reach directionality, stability and uniformity to meet the requirement of biohazardous test.
Chinese patent (publication number CN202725194 U) provides a kind of Biohazard Safety Equipment, comprise cabinet, described cabinet top is provided with exhaust outlet, described exhaust outlet bottom is provided with filter, described cabinet top is provided with airduct, described airduct is made of plastics, be connected with pressure fan in the middle part of described airduct, described cabinet both sides are respectively equipped with left air inlet and right air inlet, described left air inlet is connected with airduct with right air inlet, described cabinet bottom is provided with scouring table, flushed channel is provided with in described scouring table, described flushed channel is made up of stainless steel, described flushed channel bottom is connected with outlet pipe, described flushed channel top is provided with water inlet pipe, described water inlet pipe front portion is provided with water inlet switch.
Although technique scheme can increase the ventilation in cabinet, its defect is the air velocity of each position in cabinet and unbalanced, easily causes identical a few increment product to be in different temperature, humidity environment at different putting positions.
Utility model content
The technical problems to be solved in the utility model is to overcome the unbalanced defect of prior art air velocity, the flowing of air in a kind of cabinet is provided evenly Biohazard Safety Equipment.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of Biohazard Safety Equipment, its feature is, it includes a top wind gathering cover, an operating room, a wind gathering chamber and a blower fan;
Described wind gathering chamber is arranged at the top of described operating room, is provided with first filter course for filtering between described wind gathering chamber and described operating room;
Described wind gathering cover is arranged in described wind gathering chamber, and described wind gathering cover is towards described first filter course;
Described blower fan one end is communicated with external source of air, and other end opening and described opening are towards described wind gathering cover;
Described operating room and ft connection place are provided with one second filter course;
Described wind gathering cover is bowl-type.
That is, envelope is blown by blower fan thinks wind gathering cover, and because wind gathering cover is bowl-type, air-flow thinks that bowlshaped mouth is dispersed and conducts to the first filter course between wind gathering chamber and operating room uniformly.
Preferably, the outer wall of described operating room arranges some pores, described outer wall is outside equipped with an interlayer, and described interlayer and ft connection are also filled with filtering material.
Preferably, described interlayer is communicated with described blower fan, and described blower fan is used for, across described interlayer, the air in described operating room is guided to described wind gathering cover.
Herein, formation and above-mentioned second filter course after Sandwich filling filtering material.
Positive progressive effect of the present utility model is: guide wind direction to wind gathering cover by blower fan, changes air flow condition make the air-distribution through the first filter course more even further by wind gathering cover.
Accompanying drawing explanation
Fig. 1 is the stereogram of the Biohazard Safety Equipment of the utility model preferred embodiment.
Fig. 2 is the structural representation of the Biohazard Safety Equipment of the utility model preferred embodiment.
Detailed description of the invention
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
Fig. 1 is the stereogram of the Biohazard Safety Equipment of the present embodiment, Fig. 2 is the structural representation of the Biohazard Safety Equipment of the present embodiment, as shown in Fig. 1 ~ 2, the Biohazard Safety Equipment that the present embodiment relates to includes top wind gathering cover 1, operating room 3, wind gathering chamber 2 and a blower fan 6.Wherein, wind gathering chamber 2 is arranged at the top of operating room 3, is provided with a filter course 7 for filtering between wind gathering chamber 2 and operating room 3.
Filter course 7 adopts ultra high efficiency air cleaner (ULPA), ULPA (Ultra Low PenetrationAir Filter) full name is ultra high efficiency air cleaner, or claim ultralow penetrance air cleaner, more than 99.999% is reached to the filter efficiency of the dust particles such as the particulate of 0.1 ~ 0.2 μm, smog and microorganism.ULPA is at HEPA (High efficiency particulate air Filter, high efficiency particle air filter) basis on through further enhancing the filter effect of HEPA, ULPA reaches more than 99.9999% to the atomic filter efficiency of more than 0.3 micron.ULPA and HEPA compares, and filter structure is compacter, filter efficiency is higher, but simultaneously, resistance is also higher.Ulpa filter feature: filter core ultra-fine fibre glass filtrate economy-combat glue is folding to be formed, housing can select Sandwich board, zinc-plated copper coin, corrosion resistant plate and aluminium alloy plate, closely bonded by polyurethane adhesive, have that quality is light, Air permenbility is large, dust collection efficiency is up to 99.95-99.999%, and it is alkaline-resisting, high temperature resistant.Be applicable to 10000 grades of-100 grades of clean systems, air-conditioning system, therefore product has been widely used in electronics, microelectronics, semiconductor, optical device, biology and multiple field such as medical circuit, camera and optical instrument, precision optical machinery etc.
Filter is the key composition in Biohazard Safety Equipment, mainly plays the effect of filter bacteria and dust granule, to purify the gas being blown into safety cabinet workspace He giving off.The filter used in safety cabinet must have enough filter efficiencies, otherwise does not just have the effect of protection against biological harm.Filter material should adopt silicate glass fiber.In current safety cabinet, normal employing is have to 0.3 μm of dust particle the HEPA high efficiency particulate air filter that efficiency of damming is 99.99%, and the ULPA super high efficient filter of the efficiency of damming of 99.9998%.The latter has better filter efficiency, more closely structure and larger unit filter area, can be working region and provides the cleanliness factor being equivalent to ISO 3 grades.
Wind gathering cover 1 is arranged in wind gathering chamber 2, and wind gathering cover 1 is towards filter course 7.Wind gathering cover 1 is bowl-type.The outer wall of operating room 3 arranges some pores, and outer wall is outside equipped with an interlayer 8, and interlayer 8 is communicated with blower fan 6, and blower fan 6 is for guiding to wind gathering cover 1 across interlayer 8 by the air in operating room 3.Interlayer 8 is filled with filtering material, and the filtering material in interlayer 8 is glass fibre.
In addition, blower fan 6 by a pipeline 61 by airflow blow to the wind gathering cover 1 of bowl-type, pipeline 61 is just to the center of wind gathering cover 1, and opening is tubaeform.The bottom of operating room 3 is operating desk 4, and the sidewall of operating room 3 is provided with openable glass door.The below of operating room 3 is provided with the supporting leg for supporting whole Biohazard Safety Equipment.
