The invention provides a pitch heating device. The pitch heating device comprises a pitch pot; the top of the pitch pot is provided with a pitch inlet; the bottom on one lateral side of the pitch pot is provided with a pitch outlet. Mainly improvements comprise that the other lateral side of the pitch pot is provided with a conduction oil inlet and a conduction oil outlet; the external ends of the conduction oil inlet and the conduction oil outlet are respectively used for communicating with an inlet and an outlet in a conduction oil heating furnace; internal ends of the conduction oil inlet and the conduction oil outlet are respectively connected with two ends of a heating coil arranged inside the pitch pot. The heating coil repeatedly coils from one side of the conduction oil inlet and the conduction oil outlet and the other side inside the pitch pot further. The pitch heating device has the advantages of being simple and practical in structure, quick in heating speed, high in heating efficiency and fully satisfying the construction site progress requirement.
Description
Technical field
The present invention relates to a kind of pitch process equipment, especially a kind of asphalt heater.
Background technology
Pitch is the byproduct of Petroleum refining, but a kind of very useful industrial goods, general for road spreading, the fields such as buildings waterproof process.Pitch usually in solid-state, need then will be heated liquefaction when using, then just can construct under low temperature or normal temperature.Pitch liquefaction usually needs special firing equipment.At the scene of some Interim uses, a bowl also can be used to melt a small amount of pitch, but fusing amount only can meet considerably less spread out and put on area, such as damages the repairing in face for fritter road.For the construction demand needing a large amount of molten asphalt, asphalt heating melting appartus must be used.
And the existing asphalt heater ubiquity efficiency of heating surface is not high on market, firing rate is slow, is difficult to meet the problems such as the needs of rapid construction progress.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of asphalt heater, it relies on the heat endlessly introduced external heat source and produce, and by inside interchange of heat fast, therefore the efficiency of heating surface is high, and firing rate is fast.The technical solution used in the present invention is:
A kind of asphalt heater, comprise an asphalt tank, be provided with pitch entrance at the top of asphalt tank, be provided with asphalt outlet in a side bottom of asphalt tank, main improvements are:
Another side of described asphalt tank is provided with heat conductive oil inlet and conduction oil outlet, conduction oil imports and exports outer end for connecting the import and export on heat-conducting oil heating boiler respectively, and the inner that conduction oil is imported and exported is connected with the two ends of the heat(ing) coil be arranged in asphalt tank respectively.
Further, described heat(ing) coil returns back and forth multiple from U-shaped dish between opposite side in conduction oil import and export side in asphalt tank and asphalt tank.
Further, the bottom of asphalt tank inside is located at by described heat(ing) coil, and correspondingly, the bottom of asphalt tank side is also located in heat conductive oil inlet and conduction oil outlet.
The invention has the advantages that: this device simple and practical, firing rate is fast, and the efficiency of heating surface is high, fully can meet the progress demand of job site.Electric heater unit is not established in inside, and safeguard simple, maintenance cost is low.
Accompanying drawing explanation
Fig. 1 is structure of the present invention composition schematic diagram.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1: asphalt heater proposed by the invention, comprise an asphalt tank 1, be provided with pitch entrance 6 at the top of asphalt tank 1, be provided with asphalt outlet 5 in a side bottom of asphalt tank 1.
Existing asphalt heater generally adopts the structure from heating, such as in asphalt tank, arranges electric heater, but is limited to the power of interior heater, and often firing rate is fast not, when pitch is spread out and put on fast, does not catch up with construction speed.Interior heater also damages than being easier to, and maintenance comparatively not easily.
For this reason, design concept of the present invention is to introduce outside thermal source, the heat that such as heating boiler produces, then the ability heated can improve greatly.
Another side of above-mentioned asphalt tank 1 is provided with heat conductive oil inlet 2 and conduction oil outlet 3, conduction oil imports and exports outer end for connecting the import and export on heat-conducting oil heating boiler respectively, the inner that conduction oil is imported and exported is welded to connect with the two ends of the heat(ing) coil 4 be arranged in asphalt tank 1 respectively, to ensure that conduction oil can free in and out, successfully pass through in internal heating coils 4.
Preferably, the bottom of asphalt tank 1 inside is located at by heat(ing) coil 4, and correspondingly, the bottom of asphalt tank 1 side is also located in heat conductive oil inlet 2 and conduction oil outlet 3.On the one hand heat transmits than smoothly from the bottom up, and when pitch is fewer, this device also can use on the other hand.
Preferably, heat(ing) coil 4 returns back and forth multiple from U-shaped dish between opposite side in conduction oil import and export side in asphalt tank and asphalt tank, fully to ensure that conduction oil in heat(ing) coil 4 is by the pitch sufficient heat exchange in heat(ing) coil 4 tube wall and tank.
When needs heated asphalt, add pitch by the pitch entrance 6 on top, the conduction oil then through external boiler heating is gone out by transport pump.According to the needs of firing rate, the thermal power size of external heat boiler and the feed flow speed of pump can be set.
Conduction oil is when flowing through asphalt tank 1 internal heating coils 4, and heat is come out by tube wall, thus heated asphalt.Because conduction oil circulates between boiler and asphalt tank 1 always, make asphalt heating speed.
