Description
Technical field
The present invention relates to a kind of labware, particularly relate to a kind of clean work station.
Background technology
Clean work station is a kind of air cleaning facility providing local high-cleanness, high working environment versatility stronger, its use, to improving process conditions, improves product quality and increase yield rate all has good result, it is possible to connect into assembling line, there is low noise, the advantages such as mobility is strong.It is widely used in medical and health, bio-pharmaceuticals, food, medical science experiment, optics, electronics, sterilizing room experiment, aseptic Micro biological Tests, plant tissue culture inoculation etc. and needs the research and production department of local cleaning sterile working environment.
In the particular space of clean work station, pure air forms air-flow by the direction flowing set.Dividing with airflow direction, existing clean work station can be divided into rectilinear way flow and two kinds of forms of horizontal one-way flow.Clean work station generally includes the workbench body providing work top and is located at the isolation cover above workbench body, the side wall lower ends of isolation cover is against on work top, isolation cover is sequentially provided with filter, blower fan and diffuser plate along airintake direction, after air is filtered, beaten to diffuser plate by blower fan, pore on diffuser plate flows out, and working region is purified.On tradition diffuser plate, the cross sectional shape in diffusing hole is circular, when dust or granule are attached on diffusing hole, owing to dust and granule mostly are spherical, if the diameter of dust or granule is equal to aperture, diffusing hole, it is easy to be stuck in diffusing hole, the air-out passage of blocking diffuser plate.And once blocking, owing to aperture, diffusing hole is less, it is relatively difficult to cleaning.Particularly in some need close blower fan only open bactericidal unit be operated when, dust or the especially easy sidewall being adsorbed on isolation cover of granule include on diffuser plate.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, it is provided that the diffusing hole shape of a kind of diffuser plate is special, can blockage resisting, air-out efficiency high, and the purification workbench for laboratory extended service life.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of anticlogging purification workbench for laboratory, including workbench body and the isolation cover being arranged in described workbench body, described isolation cover at least front openings, the dorsal part of described isolation cover is sequentially provided with forward air-supply arrangement and diffuser plate, inside described isolation cover, below roof, it is additionally provided with bactericidal unit, it is characterized in that: described diffuser plate is provided with some diffusing holes, the described diffusing hole at least opening shape on diffuser plate leading flank is rectangle, and described rectangle width is less than 1mm.
Preferably, described rectangle length is 1.2-1.5 times of width.
Preferably, described diffuser plate is provided with 100-150 described diffusing hole.
Preferably, on described diffuser plate, the left and right sides is distributed less described diffusing hole respectively, the described diffusing hole that intermediate distribution is more.
Preferably, the opening in described diffusing hole is gradually increased by diffuser plate leading flank side surface direction backward.
Preferably, the hole wall in described diffusing hole is curved surface.
The invention solves the defect existed in background technology, have the advantages that
1. purification workbench for laboratory of the present invention, on diffuser plate diffusing hole be shaped as differing from the rectangle of typical round, rectangular width is less than 1mm on the one hand, less than the diameter of usual dust and granule, it is to avoid dust and granule are stuck in diffusing hole；Even if the diameter of dust or granule is equal to rectangle width on the other hand, being stuck in diffusing hole, the rectangular shape in diffusing hole can also retain certain air-out area for it, it is ensured that air-out is normal.When rectangle length is 1.2-1.5 times of width, it is ensured that air output preferably.
2. diffuser plate arranges 100-150 diffusing hole, takes into account air output and avoid providing too much potential jam object into dust and granule.
3. less diffusing hole can be distributed respectively in the left and right sides of diffuser plate, the diffusing hole that intermediate distribution is more, thus meeting the usual operating habit of those skilled in the art, namely most of actions complete in the middle part of working region, both sides are then less, and therefore design middle part diffusing hole number is more, fully meets air-conditioning requirement, both sides quantity is few, saves unnecessary energy consumption.
4. the opening in diffusing hole is gradually increased by diffuser plate leading flank side surface direction backward, even if having dust or granule to be embedded in diffusing hole, also easily skids off from rear.Especially the hole wall in diffusing hole is designed as curved surface, further increases the probability that dust or granule skid off from rear, diffusing hole.

Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of the preferred embodiments of the present invention；
Fig. 2 is the front view of diffusing hole rectangle 811 in the preferred embodiments of the present invention；
Fig. 3 is the side view cutaway drawing in diffusing hole in the preferred embodiments of the present invention；
In figure: 2, workbench body, 4, isolation cover, 41, roof, 6, air-supply arrangement, 8, diffuser plate, 81, diffusing hole, 811, rectangle, 812, curved surface, 82, leading flank, 83, trailing flank, 12, bactericidal unit.
Detailed description of the invention
Presently in connection with drawings and Examples, the present invention is further detailed explanation, and these accompanying drawings are the schematic diagram of simplification, and the basic structure of the present invention is only described in a schematic way, and therefore it only shows the composition relevant with the present invention.
As Figure 1-3, a kind of anticlogging purification workbench for laboratory, including workbench body 2 and the isolation cover 4 being arranged in workbench body 2.On front side of isolation cover 4 and bottom end opening, the dorsal part of isolation cover 4 is sequentially provided with forward air-supply arrangement 6 and diffuser plate 8, and isolation cover 4 is internal, be additionally provided with bactericidal unit 12 below roof 41.Diffuser plate 8 is provided with some diffusing holes 81, and the diffusing hole 81 cross section in axial optional position is rectangle, and wherein the width of the rectangle 811 on diffuser plate 8 leading flank is less than 1mm.
Concrete, rectangle 811 length a is 1.2-1.5 times of width b.The opening in diffusing hole 81 is gradually increased to trailing flank 83 direction by diffuser plate 8 leading flank 82, and each hole wall in diffusing hole 81 is the curved surface 812 protruded to direction, axis, diffusing hole 81.Curved surface 812 is at 4-5 times that radius of curvature is rectangle 811 width b of cross-wise direction as shown in Figure 2, and the dust of jam or granule are more easy to and skid off.
Diffuser plate 8 is provided with 100-150 diffusing hole 81.On diffuser plate 8, the left and right sides is distributed less diffusing hole 81 respectively, the diffusing hole 81 that intermediate distribution is more.
In the present embodiment, the width of rectangle 811 is less than 1mm, the diameter dust more than 1mm and granule is not only made to cannot be introduced into and jam diffusing hole 81, even if diameter has been stuck in diffusing hole 81 equal to the dust of 1mm and granule, owing to cross section, diffusing hole 81 is rectangle, it is possible to reserve enough incoming air areas；And if the diameter of dust and granule is equal to 1mm, being then directly entered diffusing hole 81, without resulting in blockage.
Above according to the desirable embodiment of the present invention for enlightening, by above-mentioned description, related personnel in the scope not necessarily departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content in description, it is necessary to determine technical scope according to right.
