Description
Technical field
The utility model belongs to primer charge experimental facilities, particularly relates to a kind of primer charge ignition performance research experiment instrument.
Background technology
In order to the medicament of the Loading Materials for Initiating Explosive Devices that ignites, firework medicament, propellant and propellant powder.Can be divided into simple substance and mixing two classes by composition, can be divided into by performance has that gas, micro-gas, first gas, deflagration, quick burning, cold combustion, dark combustion, high temperature resistant, insensitiveness, extension etc. are multiple can be divided into for detonator, illuminating agent, smoke agent, tracer mixture, flare, propellant etc. dissimilar by purposes.
The actual primer charge used mostly is priming composition, forms primarily of oxygenant, fuel agent and adhesive.Requirement physical and chemical performance is stablized, responsive to thermal shock, has enough ignition abilities, and reliable effect.Fill in various ignition device.
The ignition performance of primer charge then plays vital effect for the initiation coefficient of stabilization of ignition device.
And the research of primer charge security performance, as the infrastest of university's burning with blast course, in order to guiding students digesting for knowledge point, and for the cultivation of experimental spirits.A good experimental facilities is absolutely necessary.
Now for the experimental facilities of primer charge security performance research, few, majority assembles for teacher oneself temporarily, so ought to research and develop a experiment equipment being exclusively used in the research of primer charge ignition performance.
Summary of the invention
The utility model solves conventional point pyrophoric ignition performance test equipment and lacks, and cannot carry out rationally effective experiment, is that experiment increases a large amount of difficulty, and experiment flow not shortcoming easily.
A kind of primer charge ignition performance research experiment instrument, comprise firing chamber, be arranged with universal stage in described firing chamber, in described universal stage, motor is installed, described motor is connected with the power pack be arranged on outside described firing chamber by wire, and described power pack is provided with release knob; Described universal stage is fixedly connected with straight-bar, described straight-bar end is connected with by the primer charge clamper of center outwards in dispersion shape, described primer charge clamper end offers one with the gap of ripple struction, also comprises an arc ignition device for lighting a fire for primer charge.
Wherein, described primer charge clamper is metal material.
Wherein, described firing chamber is provided with view window, and described view window material is acrylic.
Wherein, exhaust smoke hole is provided with above described firing chamber.
Wherein, below described firing chamber, offer ash-falling hole, below described ash-falling hole, be provided with dust disposable box.
The beneficial effects of the utility model are: simplify ignition performance research experiment and repeat step, and reduce ignition performance research experiment required time, security performance is high, is beneficial to the advantages such as observation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, further detailed description is done to the utility model.
Fig. 1 is the structural representation of a kind of primer charge ignition performance of the utility model research experiment instrument;
Fig. 2 is the structural representation of the utility model primer charge clamper.
Embodiment
Primer charge ignition performance is studied, and often carries out comparative tests, and from proportioning, to selecting material, to ignition ability size, often often organizing contrast experiment all needs to carry out up to a hundred groups.
Great many of experiments causes too much repeatability work, if can not simplify repeatability work, greatly reduces the enjoyment of experiment, reduces the enthusiasm of student for experiment.
And the uninteresting work of a large amount of repeatability, easily causes physical fatigue, reduce experiment safety coefficient, cause dangerous hidden danger.
The utility model is according to situations such as primer charge ignition performance experiment flow, requirements, and research and develop a efficient experiment equipment being applicable to this experiment, concrete scheme is as follows:
As illustrated in fig. 1 and 2, a kind of primer charge ignition performance research experiment instrument, comprise the firing chamber 1 as combustion experiment place, universal stage 2 is provided with in described firing chamber 1, motor for providing power for described universal stage 2 is installed in described universal stage 2, described motor is connected with the power pack 3 be arranged on outside described firing chamber 1 by wire, and described power pack provides electric energy for described motor.
Described power pack 3 being provided with release knob 4, by controlling the folding of described release knob 4, and then controlling the running of described motor, thus drive described universal stage 2 to rotate.
Described universal stage 2 is fixedly connected with straight-bar, described straight-bar end is connected with by the primer charge clamper 5 of center outwards in dispersion shape, described primer charge clamper 5 end offers one with the gap 6 of ripple struction, also comprises an arc ignition device 7 for lighting a fire for primer charge.
Before experiment starts, primer charge is arranged in described gap 6, because described gap has ripple struction, described ripple struction both can produce anti-skidding effect, prevent primer charge from coming off in experimentation, again can be not of uniform size by the spacing between opposition ripple, settle the primer charge of different thicknesses.
After primer charge is all placed, press described release knob 4, described motor is come into operation, universal stage 2 slow circumvolve described in described driven by motor, now the primer charge of the described gap of described primer charge clamper 5 end can be lighted a fire by arc ignition device successively.
Owing to once can carry out organizing experiment simultaneously, greatly reduce the time spent by experiment more, and easy experimentation, reduce duplication of labour rate.
And moved by Mechanical course primer charge, lighted a fire by described arc ignition device 7, experimental combustion whole process is in described firing chamber, has greatly ensured the safety of experimenter.
In some optional embodiments, described primer charge clamper 5 is metal material, and metal material is easy to cleaning, and can not produce dangerous due to the burning of primer charge.
In some optional embodiments, for the ease of the observation of experimenter, described firing chamber 1 is provided with view window, and described view window material is acrylic.
In some optional embodiments, above described firing chamber 1, be provided with exhaust smoke hole 8, be beneficial to and combustion fumes is got rid of, be convenient to observe and be convenient to keep Laboratory air to clean.
In some optional embodiments, below described firing chamber 1, offer ash-falling hole, below described ash-falling hole, be provided with dust disposable box 9, centralized collection, be convenient to recycling, prevent dangerous generation.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; other are any do not deviate from Spirit Essence of the present utility model and principle under the change made; modify; substitute, combination, simplify; all should be the substitute mode of equivalence, all should be included in protection domain of the present utility model.
