Abstract
The utility model provides a smoke ventilator for a laboratory. The smoke ventilator for the laboratory comprises a trumpet-shaped exhaust fume collecting hood arranged on a ceiling. The rear portion of the exhaust fume collecting hood is connected with a smoke flue, and an exhaust fan is arranged in the smoke flue. The smoke ventilator for the laboratory is characterized in that a plurality of guide rails are vertically arranged on the ceiling, the exhaust fume collecting hood is movably arranged on the guide rails, and the ceiling is further provided with an air cylinder driving the exhaust fume collecting hood to move along the guide rails. According to the smoke ventilator for the laboratory, the height of the exhaust fume collecting hood is adjusted through a remote-control unit, operation is convenient, further, the smoke ventilator for the laboratory can be close to a coating machine to discharge smoke, and smoke-exhaust effect is good. The smoke ventilator for the laboratory has the advantages of being simple in operation, environmental-friendly and the like.
Description
Technical field
The utility model relates to a kind of induced-draft fan, the induced-draft fan that especially uses in the laboratory.
Background technology
Coating machine for the production of film is a kind of common device, and its effect briefly is that coating is coated on the release liners equably by nozzle, forms film, and coating wherein can be PUR.During coating machine work, can produce a large amount of poisonous PUR flue gases, flue gas must be discharged to outdoor.Mostly adopt at present an induced-draft fan is set above coating machine, the exhaust fume collecting hood of induced-draft fan is a large cover, is used for collecting the flue gas that rises, and then discharges outdoor by flue.This exhaust fume collecting hood generally all is to be fixedly mounted on the ceiling, and invariant position is usually higher, be convenient to workman's operation, so smoke discharging effect is slightly poor, always has partial fume to be taken out of by indoor flow perturbation, thereby is diffused into whole indoor.In the large-sized workshop of factory, the space is large, ventilation effect good, the smoke discharging effect of this exhaust fume collecting hood or acceptable.But the coating machine that uses in, the poor laboratory that ventilates little for the space, this smoke discharging effect are just dying, and some flue gas of diffusion will so that be full of pungent smell in the whole laboratory, also have a strong impact on the healthy of staff.
The utility model content
For defects of the prior art, the utility model provides a kind of use for laboratory induced-draft fan, and the exhaust fume collecting hood height of this use for laboratory induced-draft fan can be regulated, when not needing the workman to operate, can be close to coating machine to exhaust fume collecting hood, thereby greatly increase its smoke discharging effect.
A kind of use for laboratory induced-draft fan described in the utility model, it comprises the tubaeform exhaust fume collecting hood that is arranged on the ceiling, connect flue behind the described exhaust fume collecting hood, be provided with air exhauster in the described flue, it is characterized in that: be vertically installed with some guide rails on the described ceiling, described exhaust fume collecting hood is arranged on the described guide rail movably, also is provided with on the described ceiling to drive the cylinder that described exhaust fume collecting hood moves along described guide rail.
Preferably, its also comprise one be connected the infrared signal receiver that cylinder connects and the remote controller of controlling described infrared signal receiver.
Preferably, described air exhauster is arranged on outdoor, can effectively reduce noise.
Use for laboratory induced-draft fan of the present utility model is by the height of remote controller adjusting exhaust fume collecting hood, and is easy to operate, and can press close to coating machine and discharge fume, and smoke discharging effect is good.The advantages such as that use for laboratory induced-draft fan of the present utility model has is simple to operate, environmental protection.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
In order to make those skilled in the art person understand better the utility model scheme, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with embodiment and embodiment accompanying drawing the utility model is described in further detail.
As shown in Figure 1, a kind of use for laboratory induced-draft fan of the present utility model comprises the tubaeform exhaust fume collecting hood 12 that is arranged on the ceiling 10, and exhaust fume collecting hood 12 rear connection flues 14 are provided with air exhauster (not shown) in the flue 14.Air exhauster is arranged on outdoor, can effectively reduce noise.Be vertically installed with some guide rails 16 on the ceiling 10, exhaust fume collecting hood 12 is arranged on the guide rail 16 movably, also is provided with on the ceiling 10 to drive the cylinder 18 that exhaust fume collecting hood 12 moves along guide rail 16.In addition, comprise that also one is connected the infrared signal receiver 20 that connects and the remote controller (not shown) of control infrared signal receiver 20 with cylinder.Can as required, to infrared signal receiver 20 instruction, control cylinder 18 occur by remote controller so just, thereby regulate at any time the height of exhaust fume collecting hood 12, when nobody operates, the height of exhaust fume collecting hood 12 can be transferred to extremely low, press close to coating machine 22, thereby greatly improve the effect of smoke evacuation.
The above; it only is the specific embodiment of the present utility model; protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
Claims (3)
