Abstract
The utility model relates to a kind of coal-powder boiler, and a kind of closing in type coal stove, belongs to coal-powder boiler technical field specifically.It comprises bonnet, combustion chamber, taper connection mouth and base, and rear end, combustion chamber connects the bonnet of sealed combustion chamber, and front end connects taper connection mouth.Taper connection mouth is the pre-large post-small conical shell of diameter.The utility model structure is simple, compact, reasonable, and the conical shell adopting diameter pre-large post-small, as the taper connection mouth connecting gas flue, can extend the length of flame and concentration degree, increases the efficiency of hot aggregates; Suitably improve the temperature in combustion chamber simultaneously, enable the coal Thorough combustion entered.
Description
Technical field
The utility model relates to a kind of coal-powder boiler, and a kind of closing in type coal stove, belongs to coal-powder boiler technical field specifically.
Background technology
In asphalt mixing plant, coal-powder boiler as the heater of Drying, for heating the aggregate such as building stones, sand.Conventional coal-powder boiler front port is straight barrel type, and the sealing joint of straight barrel type is slightly poor, and air velocity is comparatively slow, and heat loss is more, and the efficiency of heating surface of aggregate is lower.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thus provides a kind of closing in type coal stove, can extend the length of flame and concentration degree, increases the efficiency of hot aggregates.
According to the technical scheme that the utility model provides, closing in type coal stove comprises bonnet, combustion chamber, taper connection mouth and base, and base is provided with combustion chamber, it is characterized in that: rear end, combustion chamber connects the bonnet of sealed combustion chamber, and front end connects taper connection mouth; Described taper connection mouth is the pre-large post-small conical shell of diameter.
Further, base is tilting base.
Compared with the prior art the utility model has the following advantages:
The utility model structure is simple, compact, reasonable, and the conical shell adopting diameter pre-large post-small, as the taper connection mouth connecting gas flue, can extend the length of flame and concentration degree, increases the efficiency of hot aggregates; Suitably improve the temperature in combustion chamber simultaneously, enable the coal Thorough combustion entered.
Accompanying drawing explanation
Fig. 1 is the utility model front view.
Description of reference numerals: 1-bonnet, 2-combustion chamber, 3-taper connection mouth, 4-base.
Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the utility model below:
As shown in Figure 1, the utility model mainly comprises bonnet 1, combustion chamber 2, taper connection mouth 3 and base 4, and base 4 is provided with combustion chamber 2.
Rear end, combustion chamber 2 connects the bonnet 1 of sealed combustion chamber 2, and front end connects taper connection mouth 3, and taper connection mouth 3 is for connecting gas flue.
Described taper connection mouth 3 is the pre-large post-small conical shell of diameter, connection combustion chamber, large diameter one end 2, and one end of minor diameter connects gas flue, can improve sealing, improves the air velocity entering gas flue simultaneously, reduces heat loss.
Described base 4 is tilting base.
The utility model structure is simple, compact, reasonable, and the conical shell adopting diameter pre-large post-small, as the taper connection mouth connecting gas flue, can extend the length of flame and concentration degree, increases the efficiency of hot aggregates; Suitably improve the temperature in combustion chamber simultaneously, enable the coal Thorough combustion entered.
