Abstract
The utility model provides a kind of solid heating device, is to wind resistance heating wire in the outside of pipeline, lagging casing is provided with duct wrap, on the outside of the lagging casing and pipeline between be filled with magnesia powder；It is further fixed on detecting the temperature sensor of pipeline hull-skin temperature in the lagging casing, the temperature sensor connects control system, and control system is connected to the power supply electrically connected with the resistance heating wire again.When the process system medium temperature in the temperature sensor measurement to pipeline surmounts the startup operating point, the control system disconnects the power supply and the connection of the resistance heating wire, and tracing system does not work, and can save the energy.
Description
Technical field
The utility model is related to material conveying needs the industrial circle of heat tracing, is especially suitable for low temperature or high-temperature material conveyed
Heat tracing in journey.
Background technology
In some material conveying process, in order to prevent material solidification or viscosity increase, it is necessary to heat tracing.
Existing material conveys heating device typically by the use of gas or liquid as heat tracing medium, but the reduction with temperature or temperature
The rise of degree, gas or liquid can not meet the maximum temperature requirement for conveying liquid needs because oneself state changes.Particularly
Conveying material heat tracing temperature need to adjust at times or process system change material need reset heat tracing temperature or
One process system is not required to heat tracing when having different heat tracing temperature requirements or normal work, the technique system of heat tracing is just needed during parking
In system, existing heating device can not fully meet use demand.This defect exceedes heat tracing in the temperature of high temperature section, conveying material
Medium seems particularly pertinent when allowing using maximum temperature.
Utility model content
The utility model is in view of the shortcomings of the prior art, it is proposed that a kind of solid heating device.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of solid heating device, it is characterised in that：Resistance heating wire is wound in the outside of pipeline, is provided with duct wrap
Lagging casing, on the outside of the lagging casing and pipeline between be filled with magnesia powder；
Also including the temperature sensor that can detect pipeline hull-skin temperature, the temperature sensor connects control system,
Control system is connected to the power supply electrically connected with the resistance heating wire again.
Described solid heating device, wherein：The control system is also connected with siren.
Described solid heating device, wherein：The lagging casing is made up of insulation material.
Described solid heating device, wherein：The temperature sensor is fixed in the lagging casing.
When the process system medium temperature in the temperature sensor measurement to pipeline surmounts the startup operating point of setting, institute
State control system and disconnect the power supply and the connection of the resistance heating wire.
Compared with prior art, the utility model has an advantageous effect in that：It is simple in construction, it is well positioned to meet existing
The different heat tracing temperature requirements of material are conveyed, design temperature scope is roomy, and heat tracing works well.
Brief description of the drawings
Fig. 1 is the cross-sectional view of solid heating device provided by the utility model.
Description of reference numerals：Pipeline 1；Resistance heating wire 2；Lagging casing 3；Magnesia powder 4；Temperature sensor 5；Control system
System 6；Power supply 7.
Embodiment
As shown in figure 1, the utility model provides a kind of solid heating device, it is that pressure testing and air-tightness are installed in pipe-line system
After pressure testing is qualified, resistance heating wire 2 is wound in the outer helical shape of pipeline 1, then protected outside pipeline 1 on set made of insulation material
Warm shell 3, magnesia powder 4 is filled between lagging casing 3 and the outside of pipeline 1 and is sealed after consolidating；
It is further fixed on detecting the temperature sensor 5 of the hull-skin temperature of pipeline 1 in lagging casing 3, the temperature passes
Sensor 5 connects control system 6, and control system 6 is connected to the power supply 7 electrically connected with the resistance heating wire 2 again.
The utility model is suitable for needing all industrial circles of heat tracing, can set heat tracing according to the needs of process system
The startup operating point of system, when the process system medium temperature that the temperature sensor 5 is measured in pipeline 1 surmounts the startup
Operating point, the control system 6 disconnect the connection of the power supply 7 and the resistance heating wire 2, and tracing system does not work, with section
The about energy.
Control system 6 in above-described embodiment can also connect siren (being unillustrated), when the temperature sensor 5 is surveyed
Measure the process system medium temperature in pipeline 1 and surmount the startup operating point, then start the siren.
Solid heating device provided by the utility model, compared with existing liquid heating device, heating surface is uniform, without dead
Angle；Heat tracing side heat transfer coefficient is higher than liquid；Thermal conductivity factor is high, and numerical value is more than the thermal conductivity factor of various metals；Operating temperature range
Greatly, can freely be selected in normal temperature~2850 degree；Only when requiring below design temperature point, tracing system, which just starts, starts work
Make, the energy can be saved；Medium temperature can surmount the temperature of heat tracing material, also can normal work；Overall and part can all be realized
Automatically control, meet the requirement of different heat tracing temperature in process system, the solar light-heat power-generation industry fused salt that is particularly suitable for use in is ground
Hair system.
