Description

The pay-off of combustor

Technical field

The utility model relates to a kind of pay-off, is meant a kind of pay-off that can make material by equally distributed combustor around the mediad especially.

Background technology

Residual material after general cereal shells though can not eat, can produce available thermal source after burning, reach the effect of resource recovery and reusing of energy source, and have sizable value.Therefore, such as Taiwan patent announcement No. 235077 " cyclone type paddy burner ", No. 180502 " do not produce contaminated environment material～tar and sewage～a kind of rice husk incinerator new device ", No. 092604 " full-automatic chaff-fired boiler burner ", No. 080925 " rice husk incinerator new device ", No. 053772 " rice husk combustion furnace and coal smoke purifier thereof " ... etc. the patent case, main all is the mode of utilizing materials such as combusting rice hull, chaff, produces available thermal source.Though above-mentioned burner can reach the purpose that produces thermal source, but when reality is used, still there is following shortcoming and needs to be resolved hurrily: early, it mainly is the mode of toppling over manpower, material transported in the burner burn, but, the mode that manpower is toppled over makes material pile up easily, and the shortcoming of incomplete combustion, labor intensive is arranged.So; mainly all be operating type now with automation; see Fig. 1,2; with feed pipe 10 material A is delivered in the burner 20; because the material A in the burner 20 is when burning; can be in inside be created in one loop back around eddy current; therefore; outlet 11 at feed pipe 10 is to be engaged under the situation of burner 20 walls 21 tangential directions; should follow the eddy current of circulation to be stacked on an avris by the material A regular meeting that outlet 11 is fallen; the combustion efficiency that makes material significantly one is fallen, and the situation of incomplete combustion is often arranged.The purpose of this utility model provides a kind of material that can make along with the air-flow of Hui Xun in combustion furnace, the pay-off of the combustor that distributes by being scattered uniformly around the mediad.

The utility model comprises that mainly material supply device, incendivity material produce the combustion furnace of high-temperature flue gas, air blast and feed pipe, described material supply utensil has a discharging opening, described feed pipe has one and is connected section, a delivery section and an extension, this linking Duan Yiduan forms an air intake vent and can supply and is connected with air blast, reaching one can be for the blanking port that is connected with material supply device discharging opening, described delivery section level runs through combustion furnace, one end forms a feeding port and Open Side Down and with respect to middle position in the combustion furnace, described extension connects and is connected section and delivery section.By this, should can by the distribution of being scattered around the mediad, not have the situation that is deposited in an avris along with the air-flow that is circulated in the combustion furnace by the material that feeding port falls, and can contact with thermal current or gas uniformly, make and burn safer and significantly put forward the combustion efficiency of doing material.

The specific embodiment

Further specify the novel embodiment of this enforcement below in conjunction with accompanying drawing:

Embodiment one: consult Fig. 3, can store the material supply device 30 of material A and the combustion furnace 40 that an incendivity material A produces high-temperature flue gas.Pay-off comprises: an air blast 60 and a feed pipe 70.Material supply device 30 1 ends form a feeding mouth 31 and bore bigger, the other end forms a discharging opening 32 and bore is less, one run through cell wall 33 and be positioned at feeding mouth 31 belows near the rotating shaft 34 at discharging opening 32 places to the incline cell wall 33, of material of discharging opening 32 by feeding mouth 31, and a power source 35 that can drive rotating shaft 34 rotations.This rotating shaft 34 has a side face 342 that is formed with most driving levers 341, and a traversing through end that is installed with a sprocket wheel 343.This power source 35 is a motor in this preferred embodiment, have in the axle 351, of always wearing discharging opening 32 and be fixed on the sprocket wheel 352 of axle 351 traversing through end, the chain 353 of a cover di-sprocket wheel 343,352, and one is fixed on the valve wheel 354 that relative discharging opening 32 is arranged on the axle 351.There is a loading plate 41 combustion furnace 40 lower ends, and the upper end forms air port 42.But air blast 60 dispatch air-flows.Feed pipe 70 has one and is connected section 71, one a delivery section 72 and an extension 73, these linking section 71 1 ends form an air intake vent 711 and can supply and are connected with air blast 60, reaching one can be for the blanking port 712 that is connected with material supply device 30 discharging openings 32, these delivery section 72 levels run through combustion furnace 40, the one end forms a feeding port 721 and Open Side Down and relative with loading plate 41 middle positions, this extension 73 has suitable length, connects to be connected section 71 and delivery section 72.When driving 354 rotations of valves wheel when power source 35 startups and with axle 351, this valve wheel 354 will form a block effect to the material A of whereabouts, and material A is rotated and velocities of rotation with valve wheel 354, pursues the amount whereabouts, reaches the purpose of the whereabouts amount of control material A.And driving rotating shaft 34 at chain 353 rotates simultaneously, can utilize the driving lever 341 of rotating shaft 34 to stir and group diffusing material A that is pressed in discharging opening 32 porch of piling, destroy material A because of piling up the formed arch formation of pressure, the lump that the long-pending knot of material is formed is broken up and is formed loose condition (of surface), can be fallen by discharging opening 32 smoothly.Consult Fig. 3,4,5, when the air intake vent 711 dispatch air-flows of air blast 60 towards feed pipe 70, just can be when the material supply device be released junk material A to feed pipe 70 blanking ports 712 by discharging opening 32 smoothly, carry over the delivery path of extension 73 with the airflow blow material A, beginning ejection downwards by feeding port 721 relative combustion stoves 40 loading plates 41 middle positions drops, at this moment, because combustion furnace 40 has the air-flow of circulation, therefore, the material A of this whereabouts can fall in the middle of loading plate 41 rapidly by the air-flow that air blast 60 blows, and simultaneously along with the air-flow of Hui Xun in combustion furnace 40, by the distribution of being scattered uniformly around the mediad, and do not have a situation that is stacked on an avris, and can contact with thermal current or gas uniformly, and significantly improve the combustion efficiency of material.When material supply device 30 is sent to material A the operation of burning in the combustion furnace 40, will in combustion furnace 40, produce the flue gas that has high temperature, and this has flue gas meeting channelling because stack effect makes progress of high temperature, and by air outlet 42 discharges, and guiding is as suitable purposes, for example, be directed in the crop dryer, use as oven dry cereal.
