Abstract

The utility model discloses a furnace bottom seat of a biomass stalk gasification furnace, mainly comprising a main body frame of the furnace bottom seat, an air inlet device which can be embedded and fixedly connected in the main body frame, an ash baffle plate at the bottom of the furnace bottom seat and a movable screw connected with an ash-cleaning and slag-removing port and the ash baffle plate at the bottom of the furnace bottom seat. When being installed in the biomass stalk gasification furnace, the furnace bottom seat can lead the ash cleaning and slag removing to be convenient, fast and clean, has simple operation, can lead an air inlet hole in the air inlet device to be difficultly blocked by ash and slag, lead air inlet points to be distributed uniformly, ensure stable burning gasification effect in the use process and prolong the continuous burning time of high fire.

Description

A kind of biomass stalk gasification furnace base

Technical field

The utility model relates to a kind of furnace base of biomass stalk gasification furnace.

Background technology

Existing on the market at present biomass stalk gasification furnace, especially household biomass stalk gasifier, during manipulating in some aspects, also there are some not satisfied places, such as the ash and slag disposal system and the air inlet device of main furnace body: the ash and slag disposal mouth great majority of more existing stalk gasifier main furnace bodies are arranged on a side of furnace base top, lower furnace portion, need the harder tepetate of opening out during ash and slag disposal, from lower furnace portion lime-ash is ticked time-consuming consumption power again with the iron staff of an end buckle; And design is at the air inlet device of lower furnace portion, in use often exist intake opening easily to be stopped up, cause air intake point skewness, cause the interior gasification of stove inhomogeneous by lime-ash, influence the generation effect of inflammable gas, and then influence the length of the lasting duration of service of gasification, and combustion.

Summary of the invention

The purpose of this utility model provide a kind of ash and slag disposal convenient and swift clean, operation is simple and easy and have and can make intake opening be difficult for being stopped up, making the air intake point be evenly distributed, make biomass stalk gasification furnace base simple and easy, low production cost by lime-ash.

The furnace base of a kind of biomass stalk gasification furnace described in the utility model, its mainly by furnace base main body framework, can inlay and be fixed in the nethermost ash damper of air inlet device, furnace base in the main body framework and connect below the furnace base movable screw of ash and slag disposal mouth and ash damper and form.

Use the beneficial effects of the utility model:

1. ash and slag disposal is convenient and swift totally, operation is simple and easy.The nethermost ash and slag disposal mouth of furnace base is connected by mobilizable screw greatly and with ash damper, and the switch dexterity is easy to operate.

2. the intake opening in the air inlet device is evenly distributed and is difficult for being stopped up by lime-ash, even there is a spot of thin lime-ash to bleed in the air inlet device, when opening furnace bottom ash damper ash and slag disposal, the a spot of thin lime-ash that bleeds in the air inlet device is also removed in the lump, thus can further guarantee stove in use the air intake point be evenly distributed, combustion gasification effect stability and prolong the very hot oven sustained combustion time.

Description of drawings

Fig. 1 is a furnace base main body vertical view of the present utility model.

Fig. 2 is furnace base body junction framework figure of the present utility model, and wherein 1 is furnace base body junction member, and 2 is ash damper.

Fig. 3 is for inlaying the air inlet device figure that also can be fixed in the main body framework, and wherein 3 is blast pipe, and 4 is the intake opening that communicates with burner hearth.

Embodiment

Below in conjunction with specific embodiment the utility model is further described.

Concrete structure of the present utility model is referring to Fig. 1, Fig. 2, Fig. 3.Mainly comprise furnace base main body framework, can inlay and be fixed in the nethermost ash damper of air inlet device, furnace base in the main body framework and connect the movable screw etc. of ash and slag disposal mouth and ash damper below the furnace base.After the combustion-supporting gas (being mainly air) that is advanced by the micro-blower drum blasts by a blast pipe 3 or two symmetrical blast pipes 3 again by air inlet device middle part hinge evenly shunting enter other blast pipe 3 (other blast pipe 3 that the end is connected with gas blower expose port can close envelope) with the stopper jam-pack, to enter burner hearth uniformly combustion-supporting by being distributed in the lateral intake opening 4 of blast pipe again.Stove uses after for some time as needs ash and slag disposal, as long as furnace bottom being used for the screw of fastening ash damper unclamps, ash damper 2 turns on one's side from trend one, and the lime-ash in the stove just can fall automatically in the body of heater outside, and ash damper 2 being closed also after the slag reason is clean, fastening screw gets final product again.

The foregoing description is one of embodiment of the present utility model only, is not with this restriction practical range of the present utility model, so all equivalences of doing according to shape of the present utility model, structure, principle change, all should be encompassed within the protection domain of the present utility model.

Claims

1. the furnace base of a biomass stalk gasification furnace is characterized in that: it mainly by furnace base main body framework, can inlay and be fixed in the nethermost ash damper of air inlet device, furnace base in the main body framework and connect below the furnace base movable screw of ash and slag disposal mouth and ash damper and form.

2. the furnace base of a kind of biomass stalk gasification furnace according to claim 1, it is characterized in that the ash and slag disposal system inner-cavity structure in its described furnace base main body framework is a straight tubbiness unanimous between the higher and lower levels, or top is that up big and down small tapered lower portion is straight tubbiness; Its profile is square, circular or other equilateral polygon.

3. the furnace base of a kind of biomass stalk gasification furnace according to claim 1, it is characterized in that its described air inlet device that can inlay and be fixed in the main body framework is to be cruciform or M shape constitutes by pipe or square tube, envelope is closed towards a side of burner hearth in the air inlet device center, establish the intake opening that is evenly distributed on a small quantity in the above, intake opening perhaps is not set; We opens towards a side of ash output hole at the air inlet device center, and each is provided with uniformly and is no less than three intake openings to the both sides of external blast pipe by the center.

4. the furnace base of a kind of biomass stalk gasification furnace according to claim 1 is characterized in that the size of its described ash damper is consistent or more bigger with the size and the shape of ash and slag disposal mouth with shape, as long as be convenient to the two connection and closure.
