Embodiment 1

[0014] Such as figure 1 The shown dust explosion experimental device comprises a tank body 1 provided with a cover 7 at the mouth of the tank. The tank body 1 of this embodiment is a transparent explosion-proof container made of transparent explosion-proof plastic; the bottom of the cover body 7 is provided with The positioning seam, the lid body 7 is buckled with the tank mouth of the tank body 1 through the positioning seam, and an air vent 7-1 is provided on the lid body 7. The positioning seam of the lid body 7 of the present embodiment is connected with the tank mouth The way that the mouths of the tanks of the body 1 are interlocked is clearance fit, so that when the dust detonates in the tank body 1, the lid body 7 can quickly break away from the mouth of the tank body 1. A dust container 6 communicating with the pump 2 is provided in the tank body 1, and a partition plate 5 is arranged at the bottom near the inner wall of the tank body 1, and the partition plate 5 is o...

Embodiment 2

[0017] Such as figure 2 The shown tank body is equipped with a transparent explosion-proof window 8 on the tank wall of the tank body, and the transparent explosion-proof window 8 is made of explosion-proof glass; other features are the same as in Embodiment 1.

Abstract

The invention discloses a dust explosion experimenting device, and relates to the technical field of manufacturing of experiment teaching aids. The dust explosion experimenting device comprises a tank body with a cover body at a tank opening, and a dust container arranged inside the tank body and communicated with an air pump, wherein a partition board is arranged at the inner bottom of the tank body and at a position close to the tank wall; the partition board and the inner wall of the tank body surround the dust container; a combustion vessel is arranged on one side, with the dust container, of the tank body. Compared with the prior art, the dust explosion experimenting device has the advantage that the explosion experimenting device can solve the problem that the existing dust explosion experiment is low in success rate.

Description

technical field [0001] The invention relates to the technical field of manufacturing experimental teaching aids, in particular to an apparatus for dust explosion experiments. Background technique [0002] Chemistry is an experiment-based discipline. Experimental teaching can stimulate students' interest in learning chemistry, help students form chemical concepts, acquire chemical knowledge and experimental skills, cultivate observation and experimental skills, stimulate their desire for knowledge, and help cultivate a realistic, serious scientific attitude and scientific attitude. study method. At present, the dust explosion experimental device used in the teaching of junior high school chemistry textbooks is simply made of metal cans and small plastic bottles. This dust explosion experimental device includes a tank body with a cover at the mouth of the tank, and a dust A container, which communicates with the pump through a rubber tube. During the experiment, put the lig...
