Description
Technical field
The present invention relates to the experimental rig of highway construction roadbed filling, specially a kind of gangue autoignition test device.
Background technique
Coal gangue waste occupies a large amount of soil, uses filling roadbed with coal gangues in highway construction thus, has section
About resource, the significance of protection environment.
It is well known, however, that gangue is easy spontaneous combustion, risk is brought to user, for this purpose, before use, needing to be grasped coal
The characteristic of autoigniting of spoil.
Summary of the invention
The present invention does not have the blank of experimental rig to fill up when existing gangue carries out nature performance test, provides one
Kind gangue autoignition test device.
The present invention is achieved by the following technical scheme: a kind of gangue autoignition test device, including cabinet and it is buckled in
Lid thereon is provided with the high-temperature resistant seal ring with the two sealing, and the seam crossing of cabinet and lid between cabinet and lid
It is provided with lock, the left and right sidewall inside and bottom end inside of lid inner wall and cabinet are provided with light-weight refractory brick layer, cabinet
It is provided on the inside of front-rear side walls and it is there are the permeable refractory brick layer in gap, permeable refractory brick layer is surrounded with cabinet front-rear side walls
Cavity be to divide air cavity, be provided on cabinet front wall and be provided with and divide gas with the air inlet pipe of dividing air cavity to be connected to, cabinet rear wall
The exhaust pipe of chamber connection；Being horizontally disposed in cabinet has several penetration pipes for being pierced by its right side wall, and every penetration pipe lower wall is opened
There are several cable-through holes, signal wire is installed in each cable-through hole, and the lower end of signal wire is connected with temperature sensor.
When carrying out the autoignition test of gangue, is placed in cabinet after a certain number of gangues and cabinet is sealed
Afterwards, by air inlet pipe to divide air cavity input air and disperse (temperature on average that the temperature of air inlet is surveyed by temperature sensor, it is average
It is every to rise 10 degree of ventilations 20 minutes Celsius, other time stuffiness), gas is contacted by permeable refractory brick layer with gangue and edge
Gap in gangue flowed to exhaust pipe direction, simulate gas in nature, provide condition for the spontaneous combustion of gangue；
After the heat that gangue and air reaction generate gathers certain temperature, gangue starts spontaneous combustion, passes through temperature sensing at this time
The autoignition temperature of device acquisition gangue.It has filled up existing gangue and has carried out there is no the blank of experimental rig when nature performance test.
Temperature sensor I is provided in air inlet pipe and exhaust pipe.
The temperature for entering cabinet air and the temperature after discharge cabinet are examined by adding temperature sensor I, and in fact
When monitor.
The horizontal cross-section of cabinet and lid is square shape；Penetration pipe is divided into upper, middle and lower-ranking, and every layer of front and back
To being distributed with three, the quantity of cable-through hole is three on every penetration pipe, and left, center, right is distributed.
The structure designs so that temperature accuracy further increases in the cabinet measured.
Handle is provided on lid, the quantity of handle is two, and left and right distribution.
Structure of the invention design is rationally reliable, realizes whether detection gangue can occur spontaneous combustion and autoignition temperature, in turn
The precautionary measures are targetedly taken, so that reducing in highway construction using the risk of filling roadbed with coal gangues, have prevented safety
The generation of hidden danger, and accuracy is high has the advantages that structure is simple and convenient to operate and at low cost.
