Abstract
The utility model relates to a bug dust explosion experimental apparatus which is characterized by being provided with an explosion cylinder and a portfire; the upper end of the explosion cylinder is provided with a cut; the side wall of the explosion cylinder is provided with a side hole; the lower end of the explosion cylinder is provided with a hopper; the front end of the portfire is an igniting rod and the back end is a blown ballon; the blown ballon is connected at the lower end of the hopper through a glue tube and the portfire is provided with a glue plug. The bug dust explosion experimental apparatus has the beneficial effects that: the structure ensures a quite high successful rate, no bug dust escapes, the operation steps are simple and the safety is greatly improved as well which greatly enhances the teaching effect.
Description
Affiliated technical field
The utility model relates to a kind of dust explosion experiment instrument, is the middle school chemistry experiment teaching instrument.
Background technology
At present, on middle school chemical classroom, the experiment of demonstration dust explosion be the top that deducts metal can and little plastic bottle, and each makes a call to an aperture more smaller than sebific duct in the bottom side of metal can and little plastic bottle, with sebific duct little plastic bottle and air-blowing ball is formed by connecting.During experiment, earlier flour is put into little plastic bottle, then the candle of lighting is stood on a jar internal fixation, cover jar with plastic sheet again.Go into a large amount of air from sebific duct one terminal drum, make flour be full of jar, thereby finish experiment.But in actual mechanical process, be difficult to accomplish to send into burning things which may cause a fire disaster, seal with air-blowing and dust, this three steps operation must be finished moment continuously.Moreover, cover jar with plastic sheet, can not finish sealing at all; And to realize sealing fully dangerous.The 3rd, the dust of injection is from being from the side of candle flame and mistake, can not flash fire, just burn; If the Dust Capacity that sprays is fast greatly again, candle can be blown out, and lid can be raised and not detonate.In a word, this tests due to limited conditions, is difficult to successfully.According to the document introduction, this experiment can not be done by the most schools of China so far, and teaching efficiency is had a greatly reduced quality.
Summary of the invention
The purpose of this utility model provides a kind of easy to operate, and the high dust explosion experiment instrument of success ratio is to remedy the deficiency of prior art.
The technical solution adopted in the utility model is: the dust explosion experiment instrument is characterized in that: torpedo shell and portfire are set; There is opening the torpedo shell upper end, on the torpedo shell sidewall side opening is arranged, and the torpedo shell lower end is a funnel; The portfire front end is a spark lever, and the rear end is the air-blowing ball, and the air-blowing ball is connected in the lower end of funnel by sebific duct, and plug is arranged on the portfire.
Good effect of the present utility model is: this structure has guaranteed quite high success ratio, and does not have dust to escape, and operation steps is simple, and security simultaneously also has great raising, and teaching efficiency is strengthened greatly.
Description of drawings
Below by embodiment, and in conjunction with the accompanying drawings the utility model is further described:
Fig. 1 is the structural representation of embodiment of the present utility model;
Torpedo shell 1 and portfire 2 are set; There is opening 3 torpedo shell 1 upper end, on torpedo shell 1 sidewall side opening 4 is arranged, and torpedo shell 1 lower end is a funnel 5; Portfire 2 front ends are spark lever 6, and the rear end is an air-blowing ball 7, and air-blowing ball 7 is connected in the lower end of funnel 5 by sebific duct 8, and plug 9 is arranged on the portfire 2, and plug 9 and side opening 4 cooperate the sealing of finishing torpedo shell 1, and 10 is paper, and 11 is flour, and 12 is decorative cover
Embodiment:
Embodiment:
During use, on opening 3, paper 10 is compressed earlier by decorative cover 12; Flour is added in the funnel 5 from side opening, send into burning things which may cause a fire disaster then: spark lever 6 front ends are that diameter is the asbestos rope of 3mm again, light behind the sticking alcohol that takes a morsel and send in the torpedo shell 1.Simultaneously, plug 9 is filled in the side opening 4, finishes sealing.
Pinch air-blowing ball 7 with hand, gas enters funnel 5 bottoms by sebific duct 8, and the flour 11 that blows afloat spreads in the whole torpedo shell 1, and meets burning things which may cause a fire disaster, flash fire.Form blast, the gas of blast breaks through paper 10, thereby has finished the whole process of detonating experiment.
This device can repeated multiple times use.
