Biomass pellet fuel heating stove is in due course, the heating stove of warm type of wind can give indoor air with burning heat transfer, but these heating stoves ubiquitous have the problem that the heat utilization ratio that produces the burning of biomass pellet is low, simultaneously, on the furnace wall was transmitted to some heat transfer of the biomass pellet of burning in the furnace chamber, cause furnace wall high temperature to scald the people easily, the heating stove is after using a period, because furnace is in high temperature state for a long time, make the burning oven damage easily, can not change after damaging owing to burning furnace, cause the whole scrapping of heating stove.
Disclosure of Invention
To the problems existing in the prior art, the utility model provides a biomass furnace hearth structure with high heat utilization rate, safety and long service life.
The utility model adopts the technical scheme as follows: the utility model provides a biomass furnace hearth structure, includes the furnace body, two cavities around separating into through intermediate bottom in the furnace body, back cavity upper portion is equipped with the feed bin and the spiral material feeding unit who is connected with the feed bin, conveyer pipe, and preceding cavity middle part is furnace, is equipped with the furnace gate on the furnace body wall relative with furnace, its characterized in that: the upper part of the hearth is provided with an upper mounting frame, the upper mounting frame is fixedly connected with the inner wall of the hearth, the middle part of the upper mounting frame is provided with an opening, the upper part of the upper mounting frame is fixedly connected with a plurality of smoke exhaust pipes through a mounting plate, one end of each smoke exhaust pipe corresponds to the opening in the middle part of the upper mounting frame, the other end of each smoke exhaust pipe is communicated with the upper smoke chamber, the middle parts of the hearths are respectively provided with a first fixing plate and a second fixing plate, the two ends of each first fixing plate and the two ends of each second fixing plate are fixedly connected with the inner wall of the hearth, the upper mounting frame, the first fixing plates and the second fixing plates are respectively provided with a screw hole, the upper mounting frame, the first fixing plates and the second fixing plates can be detachably mounted on the combustion furnace through bolts, one end of a conveying pipe is fixed on the, the air inlet chamber is internally provided with an air feeder, an air outlet of the air feeder is communicated with the hearth, the upper flue gas chamber is connected with a flue, and the flue penetrates through the hearth and is communicated with a lower flue gas chamber arranged at the bottom of the furnace body.
Furthermore, a gap is reserved between the inner wall of the hearth and the combustion furnace.
Furthermore, a smoke exhaust fan and a smoke exhaust port are arranged on the lower smoke chamber.
Further, the flue is provided with a plurality of the flues.
The biomass furnace hearth structure of the utility model has the advantages that the combustion furnace can be detachably arranged in the hearth through the bolts, and when the combustion furnace is damaged, the combustion furnace can be detached and replaced, thereby prolonging the service life of the heating furnace and reducing the use cost; because it all around all not all with furnace body direct contact to fire burning furnace, fire the high temperature that burning furnace produced and transmitted to in firing burning furnace air all around, increased heat exchange area, improved heat utilization rate, simultaneously, because the furnace body wall does not fire burning furnace direct contact with high temperature to the potential safety hazard that furnace body wall high temperature caused has been avoided.
