Description
Technical Field
The utility model relates to a test device of highway construction road bed filler specifically is a gangue spontaneous combustion test device.
Background
The coal gangue wastes occupy a large amount of land, so that the coal gangue is used for filling the roadbed in the highway construction, and the method has important significance for saving resources and protecting the environment.
However, it is known that coal gangue is easy to self-ignite and brings risks to users, and therefore, the self-ignition performance of coal gangue needs to be mastered before use.
Disclosure of Invention
The utility model discloses a fill the blank that does not have test device when current gangue carries out the nature performance test, provide a gangue spontaneous combustion test device.
The utility model discloses an adopt following technical scheme to realize: a coal gangue spontaneous combustion test device comprises a box body and a cover body buckled on the box body, wherein a high-temperature-resistant sealing ring sealed with the box body and the cover body is arranged between the box body and the cover body, a lock catch is arranged at a joint of the box body and the cover body, light refractory brick layers are arranged on the inner wall of the cover body and the inner sides of the left side wall, the right side wall and the inner side of the bottom end of the box body, breathable refractory brick layers with gaps are arranged on the inner sides of the front side wall and the rear side wall of the box body, a cavity formed by the breathable refractory brick layers and the front side wall and the rear side wall of the box body is a gas distribution cavity, an; a plurality of threading pipes penetrating through the right side wall of the box body are horizontally arranged in the box body, a plurality of wire passing holes are formed in the lower side wall of each threading pipe, a signal wire penetrates through each wire passing hole, and the lower end of each signal wire is connected with a temperature sensor.
When a spontaneous combustion test of the coal gangue is carried out, after a certain amount of coal gangue is placed in a box body and the box body is sealed, air is input into a gas distribution cavity through an air inlet pipe and dispersed (the air temperature of the air inlet is the average air temperature measured by a temperature sensor, the air is ventilated for 20 minutes when the temperature rises to 10 ℃ on average, and the air is not ventilated at other time), the gas is contacted with the coal gangue through a ventilating refractory brick layer and flows to an exhaust pipe along gaps in the coal gangue, the gas in nature is simulated, and conditions are provided for spontaneous combustion of the coal gangue; when the heat generated by the reaction of the coal gangue and air is accumulated to a certain temperature, the coal gangue starts to self-ignite, and the self-ignition temperature of the coal gangue is obtained through a temperature sensor. The gap that no test device exists when the natural performance of the existing coal gangue is tested is filled.
And the air inlet pipe and the exhaust pipe are both provided with temperature sensors I.
The temperature of air entering the box body and the temperature of air discharged from the box body are detected by additionally arranging a temperature sensor I, and the temperature is monitored in real time.
The horizontal sections of the box body and the cover body are square; the threading pipe is divided into an upper layer, a middle layer and a lower layer, three threading holes are distributed in the front-back direction of each layer, and the number of the threading holes on each threading pipe is three and the threading holes are distributed in the left, middle and right directions.
The structural design further improves the accuracy of the measured temperature in the box body.
The cover body is provided with two handles which are distributed left and right.
The utility model has the advantages of reasonable design reliably, realized whether can take place spontaneous combustion and spontaneous combustion temperature to detect the gangue, and then pointed take precaution measures for use the gangue to fill out the risk of building the road bed in the highway construction and reduce, stopped the emergence of potential safety hazard, the accuracy is high moreover, has simple structure, convenient operation and advantage with low costs.
