Abstract

The utility model relates to a garbage furnace with manual supply, comprising a hearth and multilayered grates for placing garbage arranged in the hearth. The utility model is characterized in that fencing intervals of all grates are arranged from top to bottom from big intervals to small intervals. The utility model improves the combustion efficiency of garbage; therefore, the environmental pollution is reduced; the garbage incinerating speed is accelerated; the capacity for treating the garbage of the incinerator can be improved.

Description

Artificial feed incinerator

The utility model relates to a kind of incinerator of artificial feed.

In the burner hearth of the incinerator of artificial feed, there is multilayer to be used to bear the fire grate of waiting to burn rubbish.In prior art, the fence of each layer fire grate is equal substantially at interval, makes rubbish of all sizes be carried at random on each layer fire grate.Because bulk rubbish is difficult for being ignited, and burns smoothly so influenced its peripheral fritter rubbish, the result not only produces a large amount of smoke pollution environments, and has influenced the efficient of disposal of refuse.

The purpose of this utility model provides the burn away the refuse artificial feed incinerator of quality of a kind of improvement.

For achieving the above object, the utility model includes the fire grate that multilayer in burner hearth and the burner hearth is used to bear rubbish, the fence of each fire grate at interval by by the upper strata to lower floor by dredging extremely close rule setting, this structure makes that the bigger rubbish of the last layer bodily form has been put, what the bodily form was less is then sifted out to following one deck, has basically formed the descending from top to bottom regularity of distribution of rubbish.Owing to got rid of the interference of bulk rubbish,, reduced the black smoke discharge capacity so fritter rubbish is able to smooth burning.On the other hand, the rubbish that lower floor is not ignited on earlier ablaze rubbish baking upper strata as yet more can fully burn after the bigger rubbish in upper strata is caught fire.And some twine the agglomerate rubbish that adhesions form by various assorted bits be broken into little rubbish in combustion processes, and then the lower floor that drops burns away, and make that so agglomerate rubbish successively cracks, stratified combustion, have further improved burning quality.

The utility model has the advantages that: owing to improved the efficiency of combustion of rubbish, therefore reduced environmental pollution, and the speed of burning away the refuse that added piece, strengthened the ability of incinerator disposal of refuse.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a general structure schematic diagram of the present utility model;

Fig. 2 is the A-A profile of Fig. 1;

Fig. 3 is the B-B profile of Fig. 1.

Referring to Fig. 1, Fig. 2, in burner hearth 1, be provided with three layers of fire grate 2 (also can be provided with more multi-layered or only be provided with two-layer) from top to bottom, the fence of the superiors' fire grate at interval 2a greater than the fence of intermediate layer fire grate 2b at interval, the fence of intermediate layer fire grate at interval 2b again greater than the fence of bottom fire grate 2c at interval.So structure can make the rubbish of sending to from inlet 3 successively be screened, form big rubbish last, little rubbish under the regularity of distribution.As further improvement, the version that fire grate can be arranged to tilt, and with inlet 3 open near the higher side of the superiors' fire grate above.This structure can make rubbish roll glide along fire grate, rubbish in the downslide process can to around scatter, thereby by more effectively screening separation.In the present embodiment, the superiors' fire grate is arranged to half as shown in Figure 1, although can make a part of rubbish just fall into the intermediate layer like this without screening, but obviously improved the flow condition of combustion air in the stove, burnt gas is more upwards flowed discharge, therefore more help the abundant burning of rubbish.

Because the utility model has improved the efficiency of combustion of rubbish, makes fire box temperature higher, therefore make the fire grate distortion of carrying rubbish recessed easily.Can below the fire grate stage casing, set up the supporting member 4 of support fire grate for this reason.For protecting supporting member itself, the water pipe of available interior logical cooling water can prevent the fire grate concave deformation as supporting member effectively with this, has prolonged service life of the present utility model.

Three sees Fig. 1,3, as further improvement, the arch cover 5 of inclination can be set above close the superiors fire grate also.The heat radiation that this arch cover reflection incineration firing produces has strengthened heating, desiccation to upper strata rubbish, has accelerated the speed of burning away the refuse.In prior art, though furnace roof also is an arch, the arch furnace roof is for the firm needs of furnace binding are provided with, because the incinerator of artificial feed mostly is with masonry is built into, so adopt the arch top so that structure is firm.The arch furnace roof is far away from the superiors' fire grate distance, and the effect of reflective thermal radiation is little, and is jack arch.And the described arch cover of present embodiment is nearer from the superiors' fire grate, can effectively heat radiation be reflexed to the rubbish of top fire grate, and arch cover tilts, and is beneficial to stove internal combustion waste gas and travels up to outlet flue and discharge.

Be further to improve the temperature in the burner hearth, as shown in Figure 1, be equipped with aperture plate 7 in the outlet flue 6 of burner hearth.Aperture plate 7 can be made with stainless steel.Aperture plate 7 melts down a part of heat retaining in the thorax, has reduced through outlet flue 6 dispersed heats, has improved fire box temperature.

For more combustion air is provided, three sees Fig. 1, is provided with the air outlet 8 that can be communicated with air blast on the burner hearth perisporium.Air blast is by each air outlet blowing-in and combustion-supporting in stove.As shown in Figure 1, 2, the air outlet branch that is positioned on the burner hearth bottom perisporium is located at relative both sides, and in burner hearth, being provided with cross section between the air outlet of both sides is the dividing wall 9 of wedge shape.Dividing wall 9 plays guide functions, and it is more even that air is flowed, and further improved the quality of burning away the refuse.
