Description
Technical field
The utility model relates to a kind of furnace of calcium carbide apparatus for measuring charge level, more particularly to one kind to be used for heat accumulating type closed calcium carbide furnace
Thermal imaging apparatus for measuring charge level.
Background technique
China is the first big country of calcium carbide production, and calcium carbide is the base stock of synthetic organic chemical manufacturing industry, is mostly used in
It produces PVC (polyvinyl chloride).The chemical name of calcium carbide is calcium carbide, and commercial designations are calcium carbide, molecular formula CaC2, and molecular weight is
64.10, industrial calcium carbide purity is about 70%-80%.
Heat accumulating type closed calcium carbide furnace is a kind of calcium carbide production new technique, coke and quick lime by crushing pressure ball high temperature preheating
After be transmitted to furnace of calcium carbide high temperature feed bin, then through expects pipe send to burner hearth occur pyroreaction generate calcium carbide.In this production process,
Since pelletizing material passes through high temperature preheating, up to 1000 DEG C, so high temperature, any detection device is all difficult to hold maximum temperature
By, along with a large amount of dust in feed bin, no matter laser material position meter or radar level gauge using effect it is all very unsatisfactory, institute
It is always a very formidable problem with the high temperature bin-level detection of the closed calcium carbide production new technique of heat accumulating type.
Because the material position of feed bin is related to the safety of the smooth of technique and production, heat accumulating type closed calcium carbide furnace feed bin is main at present
Dependence Field Force, which incessantly manually protrudes into reinforcing bar in feed bin, to be detected, and this considerably increases the labour of field worker is strong
Degree, and there is very big security risk.
The prior art one：
As shown in Figure 1, increasing the radar level gauge of purging, radar level gauge is to measure object based on time stroke principle
Position, probe are issued higher-frequency radar wave and are run with the light velocity, reflected when pulse encounters surface of material by the reception in instrument
Device receives, and converts level signal for distance signal.Radar wave can continuously emit, and realize continuous material level measurement.Needle at present
To hot environment, radar level gauge increases purging loudspeaker to reduce temperature.Nitrogen is continuously blown into casing by blow valve port
So that radar sensor loudspeaker is able to maintain low temperature shape, avoids heat from passing to flange by standpipe, then pass to instrument by flange, it is right
Radar is heated, to damage radar.
The shortcomings that prior art one：
Existing radar levelmeter highest measurement temperature is several hundred degrees Celsius, this to install nitrogen additional to measure high-temperature material
The a series of equipment such as air-blowing sweeps, pressure reducing valve, blow device, but instrument environment temperature is high and dust is big, seriously affects instrument
Normal use；In charging, dust is very big in feed bin, causes radar accidentally to survey, signal fluctuation；The wave energy that radar wave itself emits
Very low, after installing various purgers additional, wave type energy is lower.Dielectric constant also changes after medium temperature is excessively high simultaneously,
So that measurement accuracy it is difficult to ensure that.

Specific embodiment
The utility model embodiment will be described in further detail below.Do not make in the utility model embodiment in detail
The content of description belongs to the prior art well known to professional and technical personnel in the field.
The utility model is used for heat accumulating type closed calcium carbide furnace thermal imaging apparatus for measuring charge level, preferable specific embodiment party
Formula is：
One thermal imaging system is installed in high temperature feed bin side, the thermal imaging system passes through imager interface and industrial computer
Connection.
The thermal imaging system is mounted at 3 meters of high temperature feed bin side.
The bulkhead of the high temperature feed bin does not set insulating layer at the position of the thermal imaging system, uses metal material instead.
The bulkhead of high temperature feed bin position of width 100mm around the thermal imaging system does not set insulating layer, uses metal instead
Material.
For the detection case of the accumulation of heat closed calcium carbide furnace big material bin of foregoing description, the utility model provides a kind of high
Effect, simple measuring device.Cardinal principle is to utilize big material bin outer wall hot material position and hole capital after selling all securities using an infrared thermal imager
Partial temperature difference is imaged, then is analyzed, to achieve the purpose that judge material position in high temperature feed bin.Such mode realizes
Cordless successfully avoids the influence of high temperature and dust to measurement.It is surveyed for heat accumulating type closed calcium carbide furnace thermal imaging material position
Device is measured, the device of the closed bin-level detection of high temperature, high dust is adapted to production operation environment is improved, there is advanced meaning.
