Description
Technical field
This utility model relates to laboratory equlpment technical field, particularly to a kind of ventilation with safety guard
Cabinet.
Background technology
Ventilated chamber is experimental facilities common in laboratory, and it can make experimenter do contaminative and danger compares
Safety during big laboratory is protected.It is each that experiment in common ventilation cabinet can be affected burst by various factors in testing
The accident of kind, and fire incident is the most serious one.The waste gases such as flue dust are entered pipeline when air draft by ventilated chamber
Cause in pipeline with the presence of inflammable and explosive source, in the flame of ventilated chamber enters pipeline, may result in the detonation of pipeline, cause
Irremediable loss.
Make troubles because of the special ventilation environmental factors of ventilated chamber and the restriction of ventilated chamber window again, cause the intensity of a fire to be easier to
Out of control cause bigger fire.So this utility patent can be effectively reduced the generation of above security incident.
Utility model content
The purpose of this utility model is to solve the problems referred to above, it is provided that a kind of ventilated chamber with safety guard,
Play warning when ventilated chamber experiment breaking out of fire, block the effect such as flame spread, effective fire extinguishing.Technical scheme is as follows
A kind of ventilated chamber with safety guard, it is characterised in that include temperature sensor, control unit, fire extinguishing
Performance element, audible-visual annunciator and experimental power supply unit, described temperature sensor is connected with control unit in being arranged at ventilated chamber,
Described control unit connects fire extinguishing performance element, audible-visual annunciator and the experimental power supply unit of described ventilated chamber.
As further improving, described fire extinguishing performance element includes blocked valve, fire-extinguishing apparatus and dump valve, described
Blocked valve is arranged at the outside of described ventilated chamber and the junction of ventilating system, and described fire-extinguishing apparatus is arranged at top in ventilated chamber
Portion, the lower section that described dump valve is arranged in ventilated chamber.
As further improving, described fire-extinguishing apparatus is dry-chemical fire extinguishing spraying.
As further improving, the panel of described ventilated chamber is additionally provided with scram button.
Beneficial effect
This utility model device is when in experimentation, the dangerous intensity of a fire of burst is uncontrollable, and automatic or manual starting protection fills
Put, danger is preferably minimized degree, it is ensured that experimenter, the safety of ventilating system, and meet industry HSE code requirement.
Accompanying drawing explanation
This utility model is further illustrated below in conjunction with the accompanying drawings with case study on implementation.
Fig. 1 is this utility model structural representation；
Fig. 2 is safety guard structural representation.
In figure numbered:

Detailed description of the invention
By making, architectural feature of the present utility model and effect of being reached are had a better understanding and awareness, in order to relatively
Good embodiment and accompanying drawing coordinate detailed description, are described as follows:
Referring to shown in Fig. 1-2, a kind of ventilated chamber with safety guard, including temperature sensor 1, control unit 2,
Fire extinguishing performance element 5, audible-visual annunciator 3 and experimental power supply unit 4, temperature sensor 1 is arranged in ventilated chamber and control unit 2
Connecting, control unit 2 connects fire extinguishing performance element 5, audible-visual annunciator 3 and the experimental power supply unit 4 of described ventilated chamber.Fire extinguishing is held
Row unit 5 includes blocked valve 51, fire-extinguishing apparatus 52 and dump valve 53, and blocked valve 51 is arranged at the outside of ventilated chamber 6 with logical
The junction of wind system, is used for preventing ventilated chamber interior flame from diffusing in ventilation shaft；Fire-extinguishing apparatus 52 is arranged at ventilated chamber
Inner top, fire-extinguishing apparatus be dry-chemical fire extinguishing spraying, spraying be mixed gas and fire extinguishing microgranule mixture, main component be N2,
A small amount of carbon dioxide and metal salt solid grain；Dump valve 53 is arranged at the lower section in ventilated chamber, for by fire extinguishing procedure
The garbage produced enters sewer pipe.It is additionally provided with scram button, it is simple to manually boot under the state of emergency on the panel of ventilated chamber
Safety guard.
Use principle of the present utility model: when ongoing experiment occurs burning excess inside ventilated chamber, temperature passes
The danger limit signal detected is transferred to control unit 2 by sensor 1, and control unit will quickly disconnect ventilated chamber experimental power supply 4
And send sound and light alarm with the linkage of DCS fire-fighting system.Control unit 2 the most quickly opens blocked valve 51 and pipeline wind in pipeline
Machine, this blocked valve is electronic blocked valve, is closed by the ventilation shaft connecting ventilated chamber and makes flame cannot infiltrate into other ventilation ducts
In road,.Start fire-extinguishing apparatus 52 simultaneously, make fire-extinguishing apparatus 52 generate efficiently to put out a fire spraying, quick extinguishing.People is tested after fire extinguishing
Member can the material of the residual of experiment in manual flushing ventilated chamber again, as metallic sodium, Acetylenogen. etc. meet the material of water burning, can be leading
It is drawn off carrying out again water flushing, meanwhile, opens dump valve 53 and the garbage produced in fire extinguishing procedure is entered down
Waterpipe.Ventilation cabinet panel is provided with scram button 61, when finding uncontrollable situation in experimentation, it is possible to press this button hands
Dynamic this system of startup.
In sum, preferred embodiment the most of the present utility model, not it is used for limiting what this utility model was implemented
Scope, all equalizations done according to shape, structure, feature and the spirit described in this utility model right change and repair
Decorations, all should be included in right of the present utility model.
