The comburent 29 is a flooring material, and the electronic igniter 30 is fixedly connected with the top cover through an electric telescopic rod 40.
The upper end of the electric telescopic rod 40 is fixedly connected with the top cover 38 through a bolt, and the lower end of the output shaft of the electric telescopic rod 40 is fixedly connected with the electronic igniter 30 through a bolt and a nut.
The fixing frame 1 is further provided with a mounting box 41, a storage battery 42 and a microcontroller 43 are arranged in the mounting box 41, the electronic igniter 30, the first valve switch 9, the second valve switch 10, the third valve switch 33, the fourth valve switch 35, the air pressure sensor 36, the electric telescopic rod 40 and the microcontroller 43 are respectively and electrically connected with the storage battery 42, and the electronic igniter 30, the first valve switch 9, the second valve switch 10, the third valve switch 33, the fourth valve switch 35, the air pressure sensor 36 and the electric telescopic rod 40 are all controlled by the microcontroller 43.
The mounting box 41 is fixedly connected with the fixing frame 1 through bolts.
The first valve switch 9, the second valve switch 10, the third valve switch 33 and the fourth valve switch 35 are all electromagnetic switches.
Specifically, the third valve switch 33 and the fourth valve switch 35 are closed by the microcontroller 43, then the output shaft of the electric telescopic rod 40 is controlled by the microcontroller 43 to extend downwards for a certain length, so that the electronic igniter 30 approaches to the burning object 29, then the electronic igniter 30 is ignited, and then the burning object 29, i.e. the paving material, is ignited, and then the output shaft of the electric telescopic rod 40 is shortened for a certain length, so that the electronic igniter 30 is far away from the burning object 29, and thus the air in the air storage tank 27 is removed, so as to avoid affecting the subsequent detection of the air drying effect, and of course, in order to achieve this effect, the air storage tank 27 can be vacuumized by using a vacuumizing device;
then, the microcontroller 43 opens the first valve switch 9 and the third valve switch 33, and closes the second valve switch 10 and the fourth valve switch 35;
air generated by an air compressor enters the air guide pipe 3 through the air inlet pipe 6, and the drying agent 4 is arranged in the storage pipe in the air guide pipe 3, so that the air entering the air guide pipe 3 can be contacted with the drying agent 4 in the process of continuously flowing, and then moisture in the air is intercepted and absorbed by the drying agent 4, so that the air flowing out of the right end of the air guide pipe 3 is dry;
before the air processed by the drying module is subsequently utilized, whether the drying effect meets the requirement needs to be judged, that is, the dried air flows out from the left end of the air guide pipe 3 and then enters the air outlet pipe 8 and the air outlet branch pipe 31, and enters the tank body 37 through the guiding action of the extension pipe 28, then the output shaft of the electric telescopic rod 40 is extended for a certain length through the microcontroller 43, so that the electronic igniter 30 sends an instruction, the electronic igniter 30 approaches the ground paving material, and then the microcontroller 43 sends an instruction to the electronic igniter 30 to ignite the combustion object 29, that is, the ground paving material, and a user judges whether the dried air meets the requirement through observing the combustion condition of the ground paving material in the dried air;
if the drying effect of the air does not meet the drying requirement required by the subsequent flooring material combustion experiment, the air cannot be directly used for the combustion experiment so as to avoid influencing the accuracy of the flooring material combustion experiment result;
if the drying effect of the air meets the drying requirement required for the subsequent combustion experiment, the microcontroller 43 closes the third valve switch 33 to stop supplying new air to the air tank 27, so that the flooring material is automatically extinguished due to lack of oxygen after continuing to burn for a while.
And at the same time when the third valve switch 33 is closed, the second valve switch 10 is opened so that the air which has been dried and has a satisfactory drying effect flows to the flooring material combustion experimental apparatus through the air outlet duct 8.
When the dried air is introduced into the air tank 27 and the drying effect is detected, since the air is colorless and tasteless, it is difficult to observe the amount of air in the air tank 27 by naked eyes, so if the amount of air introduced into the air tank 27 is too much, it is very likely to cause a safety accident, but in the technical solution of the invention, the air pressure in the air tank 27 is monitored by the air pressure sensor 36, and is judged by the microcontroller, if the air pressure in the air tank 27 reaches a critical value, the air compressor is turned off to suspend operation, and the microcontroller 43 is used to turn off the first valve switch 9, the second valve switch 10 and the third valve switch 33, so that no new dried air enters the air tank 27, and the air pressure in the air tank 27 is reduced by the cooperation of the air release pipe 34 and the fourth valve switch 35, thereby avoiding the occurrence of safety accidents and further overcoming the potential safety hazard caused by the increase of air in the air storage tank;
if the pressure in the air tank 27 is found to be abnormally high during the combustion of the flooring material in the air tank 27, the pressure may be reduced by the cooperation of the air release pipe 34 and the fourth valve switch 35.
During the process of drying the gas, the dried air can be detected, and only the air compressor is turned off to suspend operation, and the first valve switch 9, the second valve switch 10 and the third valve switch 33 are turned off through the microcontroller 43, so that no new dried air enters the air storage tank 27 any more, and then the burned matters 29 are observed, so that the problem that the drying effect is reduced due to the failure of the drying module and the error of the result of the flooring material combustion experiment is caused due to the fact that the drying effect is unknown is avoided.
Example two
The difference between the present embodiment and the first embodiment is: the first valve switch 9, the second valve switch 10, the third valve switch 33 and the fourth valve switch 35 are all one-way valve switches.
Through the first valve switch 9, air can only flow from the air inlet pipe 6 to the air guide pipe 3, but not from the air guide pipe 3 to the air inlet pipe 6, so that the dried air is prevented from being re-humidified;
the air generated by the air compressor can only flow to the flooring material combustion experimental device from the air outlet pipe 8 through the second valve switch 10, but can not flow reversely, so that the dried air is prevented from being re-wetted or polluted;
the dried air can only flow from the air outlet pipe 8 to the exhaust branch pipe 31 and then to the extension pipe 28 through the third valve switch 33, and can not flow reversely, so that the dried air is prevented from being polluted;
through the fourth valve switch 35, the air after drying can only flow to the air escape pipe 34 from the air storage tank 27 and then flows out to the outside air, but can not flow reversely, and the outside air can not enter the air storage tank 27 through the fourth valve switch 35, so that the air in the air storage tank 27 is prevented from being polluted by the outside air.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent substitutions made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
