Abstract

A purification platform, consisting of a shelf body, a negative pressure box, and a workbench, wherein the negative pressure box is provided with an elementary-efficiency air filter, a fan unit and a high efficient air filter, and the top of the workbench is equipped with a guide plate distributed with air gate. It is characterized in that the said guide plate is set obliquely outward and the angle formed by the guide plate and the horizon is from 3degree to 60degree.The clean air of this utility model is blown out diagonally, which can cover the workbench and its marginal area of 10 cm, which is more accordant to the actual operation and can also help to solve the disadvantage that the airflow goes directly towards the operator's faces. Thus it has the good effect to improve the process conditions and guarantee high accuracy and reliability of the products; meantime the clean air flow forms ion-wind through an ion bar, which can counteract the static electricity of the work piece surface and that produced in the operation, thus, it is easy to blow away the dust, and prevent the re-absorption of the dust caused by the static electricity to ensure the work piece is ash less.

Description

Clean work station

Technical field

The utility model relates to a kind of air cleaning unit, particularly a kind of clean work station that the local air better purifying space is provided.

Background technology

Clean work station is widely used in industries such as electronics, instrument and meter, pharmacy, food, be used to provide the dustless space of part, usually, its support body is provided with work top, the air gas outlet from the deflector after filtering flows out, form clean gas flow, blow to the workspace of work top top, the space of workspace part is cleaned.Deflector in the prior art on the clean work station, be arranged vertically and horizontally disposed two kinds, vertically arranged deflector, be positioned at the rear of work top, its clean gas flow horizontal direction blows out, and directly pounces on operating personnel's face, on the one hand the operator is felt under the weather, also easily produce return air on the other hand, disturb the air-flow in the workspace, bring external dust into workspace again; Horizontally disposed deflector is positioned at the work top top, and its clean gas flow vertically blows out down from the top, can't cover the marginal portion of workbench, has dwindled the valid function area on the work top.

Simultaneously, clean work station of the prior art can not be eliminated static, is not suitable for need not having at some the occasion use of static.

Summary of the invention

The utility model purpose provides a kind of clean work station, has both guaranteed the cleanliness factor in the workspace of work top top, can not cause operator's discomfort again;

Another purpose of the present utility model is to make this clean work station be suitable for the occasion use that needs are eliminated static.

For achieving the above object, the technical solution adopted in the utility model is: a kind of clean work station, comprise support body, negative pressure box, work top, be provided with in the negative pressure box and just imitate air cleaner, blower fan group and high efficiency particle air filter, above work top, be provided with deflector, be distributed with venthole on the deflector, described deflector is oblique to be provided with outwardly, and the angle between deflector and horizontal plane is between 3 ° to 60 °.

In the technique scheme, angle between described deflector and horizontal plane can be selected according to size, difference in height and the horizontal level relation of deflector and work top in the actual design product, to obtain preferable effect, usually, the design of this angle should make clean gas flow when arriving the work top height and position, can cover outwards about 10 centimetres scope of work top edge, thereby guarantee the cleanliness factor in the work top scope, and avoid eddy current to produce.

In the technique scheme, the part of air intake, filtration can have two kinds of arrangements, the first, described negative pressure box is arranged in the support body rear portion, air inlet is positioned at the support body trailing flank, just imitate air cleaner and blower fan group and be fixed in the negative pressure box rear lower, high efficiency particle air filter is fixedly connected on negative pressure box top, and the angle between described deflector and horizontal plane is between 30 ° to 60 °.In this mode and since air-flow from backside flow to deflector, be to reduce gas-flow resistance, the angle between deflector and horizontal plane should not be too little, is advisable so select 30 ° to 60 °, correspondingly, during the deflector installation, its front position should be that the lining is better than the workbench edge.

Another kind of arrangement is, described negative pressure box is positioned at the top of support body, and air inlet is positioned at the support body top, just imitates air cleaner, blower fan group, high efficiency particle air filter and is arranged in order from top to bottom, and the angle between described deflector and horizontal plane is between 3 ° to 30 °.

In the technique scheme, because air flow to air deflector from top to bottom, the angle of deflector and horizontal plane should not be too big, and this kind of deflector outer rim can go out, also can with the work top outer rim is equal, simultaneously, for ease of the layout of production line, can on the position that is positioned on the biside plate of described support body above the work top, be provided with breach.

In the technique scheme, can below described work top, be fixedly connected with drawer and dustbin.

Further technical scheme is provided with ion bar between described high efficiency particle air filter and deflector.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

Since deflector of the present utility model from the horizontal by an angle, make that clean gas flow is oblique to be blown out, can cover outside work top and the edge thereof 10 centimetres scope, more realistic operating conditions, simultaneously also solve air-flow and directly pounced on the drawback of operating personnel's face, to improving process conditions, guarantee that product high accuracy and high reliability have good effect;

2. in further scheme of the present utility model, be provided with ion bar, make clean gas flow form ion wind by ion bar, can be with the static neutralization that produces in surface of the work static and the operation, be easy to dust is blown down, and prevent to adsorb dust once more, guarantee the purpose that workpiece is ashless owing to static.
