Description
Technical field
The utility model relates to a kind of scientific experiment apparatus, is specifically related to a kind of dust explosion demonstrating experiment device.
Background technology
Student acquires flour when learning science, coal dust can explode in certain environment, feel inconceivable, think that the combustible such as flour, coal dust dust touches air at a certain temperature and can burn, how can explode as explosive? for this reason, a kind of teaching aid is badly in need of to simulate this experiment to separate student's doubt in the heart.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of dust explosion demonstrating experiment device of transparent, safe and reliable, convenient operation.
The utility model is realized by following technological means: a kind of dust explosion demonstrating experiment device, comprise tempered glass cylinder, powder container, gas blow pipe, spring injector, wire, sparking electrode, bungee, plastic sheeting, high-tension coil, it is characterized in that:
A. tempered glass cylinder has end uncovered;
B. powder container is fixedly installed on tempered glass cylinder inner bottom part center;
C. spring injector gas outlet communicates through the gas blow pipe of tempered glass barrel;
D. two sparking electrode symmetries are fixedly installed in the middle part of tempered glass cylinder, and two sparking electrode tips are relative and spacing is 0.5 ~ 1mm;
E. tempered glass cylinder upper oral part seals by plastic sheeting bungee.
High-tension coil one end connects a sparking electrode, and the other end is connected to another root sparking electrode by the sheet metal being arranged on spring injector inner top two disconnection.
Spring of loosing one's grip again after described spring injector pulls open promotes piston and resets rapidly.
Described powder container be bowl-shape and the rim of a bowl upward.
Syringe piston top is fixedly installed sheet metal, when piston withstand spring injector foremost time this sheet metal sheet metal that can disconnect with spring injector inner top two contact simultaneously.
The described gas blow pipe mouth of pipe is being just 30 ~ 40mm to powder container center and apart from powder container distance from bottom down.
Be fixedly installed at described tempered glass drum outer wall distance oral area 10 ~ 20mm place the circular projection that a cross section is semicircle shape, this protruding circular arc portion outwardly.
During practical application, appropriate flour or fine breeze is added in powder container, with plastic sheeting by bungee by sealing suitable for reading for tempered glass cylinder, then spring injector piston is pulled out, after loosing one's grip, piston promotes to make it reset rapidly by spring, flour in powder container or fine breeze are blown afloat formation dust by the pressurized air in spring injector, simultaneously, the sheet metal of top land contacts connection with two sheet metals disconnected of syringe inner top and puts dot circuit, produce electric spark, dust touches electric spark and explodes immediately.
Owing to using tempered glass, intensity is large, even if hurt sb.'s feelings because the words of explosive failure also can not form sharp-pointed corner angle, safe and reliable, conveniently observes, successful.
Although be described preferred embodiment of the present utility model by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; under the ambit not departing from the protection of the utility model aim, can also make the concrete conversion of a lot of form, these all belong within protection domain of the present utility model.
