Description

Straw burning device

Technical field

The utility model belongs to the technical field of stalk processing equipment, is specifically related to a kind of straw burning device.

Background technology

In rural area, still there is most people to use traditional cooking stove, in use, the bio-fuels such as stalk are placed directly in into stove Interior burning, its shortcoming are, using, it is necessary to first by range burner, thermal loss is big during traditional cooking stove, especially in the winter time, it is necessary to More bio-fuels.

The content of the invention

In view of this, the purpose of this utility model is to provide a kind of straw burning device, by air blower to combustion chamber Air is supplemented, makes straw burning abundant；By setting exhaust gases passes in sidewall of the furnace body upper end, the tail gas of straw burning is discharged, Body of heater is heated using the waste heat of tail gas simultaneously so that body of heater is rapidly heated, and advantageously reduces the dosage of stalk；Filled by filtering Put the dust being mingled with filtering tail gas.

In order to achieve the above object, a kind of straw burning device of the utility model, including body of heater, fire grate, ventilation shaft, cigarette Feed channel, air blower and filter, the furnace interior have cavity and form combustion chamber, its axial direction of sidewall of the furnace body upper end edge Provided with helical exhaust gases passes, sidewall of the furnace body lower end is provided with the feeding mouth with combustion chamber, and feeding mouth side is hinged with Can cover the door body of feeding mouth, fire grate is horizontal in combustion chamber and among feeding mouth, air blower be located at body of heater outside and With air outlet, ventilation shaft one end connects with air outlet, the ventilation shaft other end through sidewall of the furnace body and combustion chamber and Below the fire grate, exhaust gases passes one end and combustion chamber, the exhaust gases passes other end and the flue outside body of heater One end connects, the flue other end and the removable connection of filter for filtration combustion dust.

Further, the filter is the cylinder with mesh end cap, cylinder suit inside and outside with flue and screw thread Connection.

Further, the feeding mouth is hinged by hinge and door body.

Further, the chamber internal surface that burns is provided with the step for being used for placing fire grate.

The beneficial effects of the utility model are：

1. a kind of straw burning device of the utility model is advantageous to economize on resources；The tail gas of straw burning enters from combustion chamber Exhaust gases passes, body of heater is heated using the waste heat of tail gas, while exhaust gases passes are twist, increase the residence time of tail gas, make Obtain body of heater to be rapidly heated, so as to reduce the dosage of stalk.

2. a kind of straw burning device of the utility model is advantageous to environmental protection；The ash being mingled with tail gas is filtered by filter Dirt.

3. filter is detachable described in a kind of straw burning device of the utility model, it is easy to the ash in flue Dirt periodic cleaning.

Brief description of the drawings

In order that the purpose of this utility model, technical scheme and beneficial effect are clearer, the utility model provides as follows Accompanying drawing illustrates：

Fig. 1 is a kind of structural representation of straw burning device of the utility model；

Reference：1- bodies of heater；2- fire grates；3- ventilation shafts；4- flues；5- air blowers；6- filters；11- Exhaust gases passes；12- feeding mouths；13- steps.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.

As shown in Figure 1；A kind of straw burning device of the utility model, including body of heater 1, fire grate 2, ventilation shaft 3, fume pipe Road 4, air blower 5 and filter 6；Body of heater 1 is built with brick, the inside of body of heater 1 has cavity and forms combustion chamber；The side wall of body of heater 1 It is axially arranged with helical exhaust gases passes 11 to upper end edge, and the side wall lower ends of body of heater 1 are provided with the feeding mouth 12 with combustion chamber； The side of feeding mouth 12 is hinged with the door body that can cover feeding mouth 12, and here, feeding mouth 12 is hinged by hinge and door body；Fire grate 2 Level is in combustion chamber and among feeding mouth 12, here, builds step 13 in burning chamber internal surface, is put by step 13 Put fire grate 2；Air blower 5 is located at the outside of body of heater 1 and has air outlet, and the one end of ventilation shaft 3 connects with air outlet, ventilation shaft 3 The other end is through the side wall of body of heater 1 with combustion chamber and positioned at the lower section of fire grate 2, the one end of exhaust gases passes 11 and combustion chamber, cigarette The other end of gas passage 11 connects with one end of flue 4 outside body of heater 1, here, ripple is used when building body of heater 1 Pipe, exhaust gases passes 11 are formed by bellows；The other end of flue 4 and the filter 6 for filtration combustion dust are removable Formula connects；Filter 6 is the cylinder with mesh end cap, and cylinder inside and outside flue 4 with being set with and being threadedly coupled, here, External screw thread can be set on cylinder, the internal thread matched with external screw thread screw thread is set on flue 4, cleared up in flue 4 Dust when, only cylinder need to be screwed out from flue 4.

The course of work of present embodiment：Stalk is sent on fire grate 2 by feeding mouth 12, lights stalk, closes door body； Air, air flows upwards are persistently supplemented to combustion chamber by air blower 5 so that flame concentrates upward, flame height, straw burning Fully；The tail gas of straw burning enters exhaust gases passes 11 from combustion chamber, and body of heater 1 is heated using the waste heat of tail gas, while flue gas Passage 11 twist, increases the residence time of tail gas so that body of heater 1 is rapidly heated, so as to reduce the dosage of stalk；Tail gas is most Discharged eventually by flue 4, the dust being mingled with tail gas is filtered by mesh end cap.

Finally illustrate, preferred embodiment above is only unrestricted to illustrate the technical solution of the utility model, to the greatest extent The utility model has been described in detail by above preferred embodiment for pipe, but those skilled in the art should manage Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details The scope of restriction.
