Abstract
The utility model discloses a coal cloud explosion observation device on a coal dust explosion identification instrument, and relates to a coal dust explosion observation device. The device is provided with a round tube which is made from transparent material, an observation hole is formed in one end of the round tube, and scales are formed by taking the observation hole as a center and form right angles with the observation hole. The device has the advantages of simplicity in structure, convenience for observation and operation, direct viewing, quickness, good effect, long operating time, high temperature resistance and wide application scope.
Description
Technical field
The utility model relates to a kind of coal dust explosion observation device, specifically the coal cloud blast observation device on a kind of coal dust explosion assessing instrument.
Background technology
Observation device under prior art in use, because it is single, observation and comparison is fuzzy, there is no scale, perhaps directly sticks the papery scale, runs into high temperature and easily melts; Direct fixing steel ruler easily blocks operating personnel's sight line, easily interfere during operation, and quartz glass tube is not easy to fix; Can bring very large trouble to the workman, and inefficiency, not only affect user's mood, and work efficiency is also had a significant impact.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides the device of the coal cloud blast observation on a kind of coal dust explosion assessing instrument, is convenient to observation, easy to operate.
The utility model is realized with following technical scheme: the coal cloud blast observation device on the coal dust explosion assessing instrument, comprise the pipe of being made by transparent material, an end at pipe has observation port, becomes the place, right angle of 90 degree to be provided with scale mark centered by observation port and with observation port.
The beneficial effects of the utility model are: simple in structure, be convenient to observe, easy to operate, directly perceived, quick, effective, work duration, high temperature resistant; Applied widely, not only be applicable to working seam and geologic prospecting coal seam and carry out the coal dust explosion evaluation, also be used in the departments such as metallurgy, geology, teaching and scientific research, to measure the explosivity of various coal samples.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
In figure: 1, pipe, 2, observation port, 3, scale mark.
Embodiment
As shown in Figure 1, coal cloud blast observation device on the coal dust explosion assessing instrument adopts the pipe 1 of being made by transparent material, has observation port 2 at an end of pipe, becomes 90 places, right angle of spending to be provided with scale mark 3 centered by observation port and with observation port.
In the present embodiment
,Described pipe 1 adopting quartz glass is made.The internal diameter of described pipe 1 is 75mm, and external diameter is 81mm, and long is 1400mm, and the diameter of observation port 2 is 14mm, apart from mouth of pipe 400mm.
Scale mark 30～500mm, scale are the every lattice of 1mm, and direct engraving is on pipe.
In use, the coal dust cloud can effectively form blast air chamber space when contacting with heating rod, and people's eyes are directly observed the explosion length of coal dust cloud, and length numerical value directly directly reads on quartz glass tube.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of invention.
