Abstract

An agricultural straw gasifier is characterized in that a feeding plate (4) and a fire grate (7) are vertically arranged; an interval is arranged between the feeding plate (4) and the fire grate (7); the fire grate (7) is combined with a fire grate supporting plate (10) into a whole; an air channel (5) is arranged between the fire grate (7) and the front surface of a gasifier body shell (6); the air channel is tightly combined with the bottom of a hearth inner wall (3) and the left surface, the right surface and the back surface of the gasifier body shell (6) to form a C-shaped secondary air chamber (12); a C-shaped fire retaining ring (14) is also arranged at the upper part of the C-shaped secondary air chamber (12) positioned in a combustion chamber; and an air inlet ash hopper (8) is arranged at the lower part of a gasifier body positioned on the upper surface of a base (9). The agricultural straw gasifier is convenient to feed at any time as requirement, saves the fuel and reduces the time of first-phase preparations; moreover, the agricultural straw gasifier is closer to the traditional cooking habits of ordinary people; and the wide application of the gasifier in rural areas plays an active pushing role in relieving the tense situations of China's energy resources, implementing the comprehensive utilization of straws, protecting the rural ecological environment and realizing the low-carbon life.

Description

Agricultural stalk gasifier

Technical field

The utility model relates to agricultural crop straw comprehensive utilization equipment, is to utilize farming, woods, herd abandoned biomass and directly burn, and is used to a kind of cooking stove of heating up water, cooking, especially direct-fired domestic energy-saving stove and accessory.

Background technology

Factors such as at present, biomass cooking stove and accessory of the prior art is simple in structure because of it, cheap, and stalk resource is extensive, and use cost is low and favored by peasant household.But because this stove and accessory still exists burning and fully and often smolders inadequately; The charcoal ash is piled up gradually and is influenced circulation of air and cause firepower not enough even extinguish; Adopt disposable reinforced mode because of again, the problem that causes the superfluous and waste of stove fuel often or add material inconvenience midway more; The quality and specification of living beings is required too strict, cause defectives such as workloads such as early-stage preparations such as firewood, chopping, compression forming are excessive, make the user in practical application, generally reflect cumbersome deficiency.

Summary of the invention

For overcoming the existing above-mentioned deficiency of cooking stove of the prior art; The technical scheme that the utility model adopted is: agricultural stalk gasifier; Comprise inboard wall of burner hearth 3, delivery sheet 4, body of heater shell 6, grate 7, ash bucket 8, base 9, grate supporting plate 10, C type secondary air chamber 12, C type fire-stop ring 14, smoke evacuation tube 16; It is characterized in that: delivery sheet 4 is the setting that is arranged above and below with grate 7, leaves spacing between the two; Grate 7 is combined into one with grate supporting plate 10, its with the front of body of heater shell 6 between leave air duct 5, with inboard wall of burner hearth 3 bottoms and body of heater shell left and right, carry on the back three tight structures formation C type secondary air chambers 12; The top of described C type secondary air chamber 12 is positioned at the combustion chamber and also is provided with C type fire-stop ring 14, to prolong the time of staying of flame in the combustion chamber, stops it directly to get into the smoke evacuation tube from discharge flue; The body of heater bottom be positioned at base 9 above be provided with air intake ash bucket 8, the inlet of being convenient to control a wind with remove dust stratification

Described delivery sheet 4 stretches out and is combined into charge door and is equipped with reinforced flap 2.

Left and right, the back of the body three faces of described body of heater shell 6 are provided with a plurality of secondary air windows 11, so that the entering of secondary combustion air.

Described inboard wall of burner hearth 3 is the C word shape, and its C type wall is disposed with secondary intake opening 13 in an orderly manner, has impelled the pyrotechnics fully burning once more of rising from burner hearth.

The beneficial effect of the utility model is: through adopting the setting that is arranged above and below of delivery sheet 4 and grate 7; And between leaves the circulation of air spacing; Solved in the past in combustion process to pile up gradually and stop air to circulate, caused the problem that firepower is not enough even extinguish between grate because of the charcoal ash.

Through time air-inlet window 11 and C type secondary air chamber 12 are set, and be provided with secondary intake opening 13 at the C of inboard wall of burner hearth 3 type wall, solved effectively cooking stove the ubiquitous burning problem of fully and often smoldering inadequately.

Stretch out and be combined into charge door and equipped reinforced flap 2 through delivery sheet 4 is set; Original cooking stove disposable feed way that adopt have been solved more; Relaxed requirement, can be convenient to add at any time material according to actual needs living beings quality and specification; Practice thrift fuel, reduced the time of preliminary preparation; Press close to common people's traditional cooking custom more, this stove and accessory to alleviating China's energy shortage situation, is implemented the stalk comprehensive utilization in the extensive use in rural area, and protection rural ecological environment is realized the low-carbon (LC) life, plays positive impetus.
