Abstract
The invention provides a super clean bench which comprises a support and a cabinet, wherein, the cabinet is internally provided with a bench; the top of the cabinet is not provided with an air inlet and an air outlet and is closed by a wind deflector; the cabinet is internally provided with a fan and a circulating air channel around the operation space of the bench; two sides and the back of the operation space of the bench are separated from the circulating air channel; a filter material is arranged between the top of the bench and the air channel; and when air flows to the top of the cabinet via the circulating air channel, the air is obstructed by the wind deflector at the top of the cabinet and filtered by a filter, then flows to the operation space of the bench at the bottom, and finally returns to the circulating air channel via the bench. The clean bench of the invention has the advantages of better filtering effect, longer service life of the filter and smaller volume.
Description
Technical field
The present invention relates to a kind of Bioexperiment equipment, be specifically related to a kind of clean bench.
Background technology
In the middle of prior art; Clean bench (being also referred to as clean work station) is widely used in industries such as medical treatment, pharmacy, food, electronics, instrument and meter and bioengineering; Its objective is the aseptic dustless space that a part is provided, to prevent the pollution of external microbe.
Super-clean bench is made air blast power by motor; Air is next through being seen off by superimposed " super cleaner " after-blow formed of special fine-celled foam lamella; Form the ultra-purify air laminar flow of dust-free sterile continuously; I.e. so-called " pure air efficiently ", it has been removed greater than the dust of 0.3 μ m, fungi and bacterial spore or the like.The flow velocity of ultra-purify air is 24～30m/min, and air possibly harassed and the pollution that causes near this enough prevented, such flow velocity can not hinder yet and adopt the calcination sterilization to apparatus etc. of alcolhol burner or Bunsen burner.Just operation under such aseptic condition of staff keeps sterilizable material not contaminated in shifting seeded process.
The structure of existing clean bench is generally as shown in Figure 1, comprises a support 20, and stent support cabinet 10 is provided with seal operation space, operating desk in the cabinet.
But the super-clean bench of prior art top exists air inlet, internal gas can't realize circulation, causes the lower problem of efficient of filtration.
Summary of the invention
To above-mentioned defective, the purpose of this invention is to provide a kind of clean bench, solving the clean bench of prior art, function singleness, and the technical problem can not circulating filtration utilized of gas.
For realizing above-mentioned purpose, the technical scheme below the present invention has adopted:
A kind of clean bench comprises support and cabinet, is provided with workbench in the said cabinet; It is characterized in that, be not provided with into and out of the air port, adopt the deep bead sealing at the cabinet top; Operating space around workbench in the said cabinet is provided with blower fan; Circulation air path, the operating space of said workbench, two sides and back all cut off with circulation air path; Between said bench-top and air channel, be provided with filter material; Gas flows in said circulation air path when flowing to the top, is stopped that by said cabinet top deep bead the back flows to the workbench operating space of bottom, gets back to circulation air path by workbench again.
According to the described clean bench of preferred embodiment of the present invention, said circulation air path comprises the main air duct between cabinet top and the bench-top, the back air channel at workbench back and the lower air duct of workbench bottom, said lower air duct, main air duct and back air channel UNICOM.
According to the described clean bench of preferred embodiment of the present invention, said workbench the place ahead is provided with observation window, and observation window comprises the glass door that can slide up and down the air inlet sealing of cabinet.
According to the described clean bench of preferred embodiment of the present invention, said workbench is provided with mesh.
Owing to adopted above technical characterictic, make the present invention than prior art, have following advantage and good effect:
At first, the present invention adopts circulation air path, and top outlet inlet is blocked, and makes gas in cabinet, continue filtration cycle, and anterior air inlet do not have the inflow air-flow basically, reduces external contamination gas and gets into, and has guaranteed the efficient of filtering;
Secondly, the present invention can reduce the pollution to filter, improves the service life of filter, and gas circulates in cabinet, and multiple times of filtration has improved the cleanliness factor of workbench operating space;
Once more, the present invention has reduced top outlet inlet and outer drain filter, can reduce the volume of clean bench, makes things convenient for the integration of compactization of clean bench.
Certainly, any one specific embodiment of embodiment of the present invention content, whole technique effect more than might not realizing simultaneously.
Description of drawings
Fig. 1 is the sketch map of prior art clean bench;
Fig. 2 is internal gas circulation pattern figure of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention done being described in further detail.
Embodiment one
Please refer to Fig. 2, the present invention provides a kind of clean bench, comprises cabinet 10, and cabinet is supported on the support, is provided with workbench 12 in the cabinet 10, top seal.
Operating spaces around workbench 12 in the cabinet 10 are provided with circulation air path, the operating space of workbench 12, and two sides and back all cut off with circulation air path.
Circulation air path comprises main air duct 21 and the back air channel 22 at blower fan 25 workbench 12 backs and the lower air duct 23 of workbench 12 bottoms between cabinet 10 tops and workbench 12 tops, said lower air duct 23, main air duct 21 and back air channel 22 UNICOMs.
Between workbench 12 tops and main air duct 21, all be provided with filter material 16.The table top of workbench 12 is provided with mesh, can realize that the gas unidirectional of gas between workbench operating space and lower air duct 23 flows.
Gas flows in said circulation air path, when flowing to the cabinet top, is stopped that the back flows to the operating space of the workbench 12 of bottom; Get back to the lower air duct in the circulation air path by workbench 12 again; Circulate the formation convection current like this, gas repeatedly is filtered in cabinet, obtains better clean effect.
Workbench 12 the place aheads are provided with observation window; Observation window comprises the glass door that can slide up and down the air inlet sealing of cabinet; Can air inlet be blocked, reduce the operating space that the outside gas of cabinet gets into workbench 12, form airtight relatively environment; And reduce personnel's hand and the possibility that the external contamination air contacts, reach the effect of clean bench.
In sum,, make the present invention, have following advantage and good effect than prior art owing to adopted above technical characterictic:
At first, the present invention adopts circulation air path, and removes the top into and out of the air port, makes gas in cabinet, continue filtration cycle, and anterior air inlet do not have the inflow air-flow basically, reduces external contamination gas and gets into, and has guaranteed the efficient of filtering;
Secondly, the present invention can reduce the pollution to filter, improves the service life of filter, and gas circulates in cabinet, and multiple times of filtration has improved the cleanliness factor of workbench operating space;
Once more, the present invention has reduced top outlet inlet and outer drain filter, can reduce the volume of clean bench, makes things convenient for the integration of compactization of clean bench.
More than disclosed only be preferred embodiment of the present invention, be not to be used for limiting itself, anyly have the knack of those skilled in the art, under the situation of spiritual connotation of the present invention, the equalization of being done changes and changes, and all should drop in protection scope of the present invention.
