Abstract
The utility model relates to a mechanical coal burning enamel kiln. The utility model is characterized in that the bottom of the combustion space of a combustion chamber is provided with a chain grate which is composed of a grate, a driving chain wheel, a driven chain wheel, an upper and a lower guide rails of a grate frame; the front and the back ends of the grate are respectively driven and supported by the driving chain wheel and the driven chain wheel; the upper part and the lower part of the grate are respectively spaced and supported by the upper and the lower guide rails of the grate frame; a coal bucket is arranged on the position at the upper part of the front end of the grate; a slag bucket is arranged between the back end of the grate and the inner wall of the combustion chamber; the lower side of the lower guide rail of the grate frame in the combustion chamber is provided with an ash bucket. The utility model has the advantages that dust is discharged without dust-removing equipment, the blackness of the dust is less than the first Ringelmen level, and the density of the dust is less than 200 mg/m < 3 >.
Description
The utility model relates to a kind of enameling furnace.
Coal-fired machinery successfully is applied to boiler and process furnace already, does not appear in the newspapers both at home and abroad but go up application at enameling furnace (stove).Now on enamelling kiln only accomplished semi-mechanized operation, promptly adopted mechanical continous-stable coal supply apparatus, as side raise coal (chain type coal, reciprocating type coal, spiral coal etc.) or under raise device for coal.These devices have certain effect reducing on the fume amount, but disclose kitchen range, when skimming, the discharging that exceeds standard of unavoidable flue dust.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and a kind of mechanical firing enamel tunnel kiln using coal as fuel is provided, and it can be finished the continous-stable coal, discloses kitchen range, the burning whole process of deslagging, thereby reaches the purpose of smoke prevention and dust control.
The purpose of this utility model realizes by following technical proposals:
Mechanical firing enamel tunnel kiln using coal as fuel, has the combustion chamber, this combustion chamber has the combustion space, vault, its technical scheme is that described combustion chamber also has and finishes coal continuously below the combustion space of being located at, disclose kitchen range, the chain type fire grate of the burning whole process of deslagging, this chain type fire grate is by fire grate, drive sprocket, driven sprocket, furnace grate support guide rail is up and down formed, before the fire grate, back two ends are supported by drive sprocket and driven sprocket transmission respectively, fire grate top, the bottom is respectively by the spacing support of lower guideway on the furnace grate support, coal bunker is located at the upper front end position of fire grate, coal gate is located on the coal bunker, air-supply position in storehouse position between the fire grate upper and lower in the combustion chamber, has slag bucket between the rear end of fire grate and the combustion chamber inwall, slag bucket upper end be provided with contact with fire grate and remove the gred remove slag plate, in the combustion chamber, be provided with ash bucket below the furnace grate support lower guideway.
The utility model is because its said structure, like this it can finish coal continuously, disclose kitchen range, the burning whole process of deslagging, rationally control coal-air ratio, the control burning distributes burning, reduces chamber temperature as far as possible, improves the temperature of quirk, and temperature is rationally distributed.It has overcome coal at traditional artificial intermittence, disclose kitchen range (poking fire), the labour intensity of skimming is big, be interrupted over-emitting black exhaust, flue dust exceeds standard, the uppity problem of furnace temperature.Overcome also in the past that the mechanical stoking device is disclosed kitchen range unescapable intermittence, smoke contamination problem when skimming.Do not need dust removal installation through experiment the utility model discharging flue dust, the flue dust blackness is less than 1 grade of Lin Geman, and concentration is less than 200mg/m

The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a sectional view of the present utility model.
Fig. 2 is the structure iron of combustion chamber in the utility model.
As shown in Figure 1 and Figure 2, the utility model only improves the combustion chamber, and other structure as chamber (case) formula kiln or tunnel oven, can be one or more combustion chambers with existing enameling furnace.Described combustion chamber 1 has combustion space 1b, vault 1c, chain type fire grate.The combustion chamber has bocca 1a.The structure of chain type fire grate is a prior art.The chain type fire grate is by fire grate 2, drive chain wheel 10 ', driven sprocket 10, lower guideway 6 and 6 on the furnace grate support ' composition, before the fire grate 2, back two ends respectively by drive sprocket 10 ' and driven sprocket 10 transmissions support, fire grate 2 tops, the bottom is respectively by lower guideway on the furnace grate support 6 and 6 ' spacing support, coal bunker 3 is located at the upper front end position of fire grate 2, coal gate 4 is located on the coal bunker 3, air-supply position between fire grate 2 upper and lowers in the combustion chamber, storehouse 5, has slag bucket 11 between the rear end of fire grate 2 and the combustion chamber inwall, slag bucket 11 upper ends be provided with contact with fire grate 2 and remove the gred remove slag plate 9, furnace grate support lower guideway 6 in the combustion chamber ' below be provided with ash bucket 12.Along the below of 1b both sides, combustion space, also can be placed with slag-proofing box 7.The side of combustion chamber 1 has peephole and inspection door 8.In the utility model when work, be transported among the coal bunker 3 by fortune coal equipment, and coal is slipped on the fire grate by deadweight, is brought in the stove by the fire grate that is moving from A-P.But when the coal gate of regulating by oscilaltion, promptly regulated thickness of coal seam on demand.Along with fire grate moves each stages such as finishing preheating and drying, burning after-flame gradually slowly backward, the lime-ash of Xing Chenging is rooted out and is fallen into slag bucket 11 by the slag plate 9 that removes that is contained in the fire grate end at last, removing slag plate also makes lime-ash prolong its retention time in stove slightly stagnating on the fire grate, make it better after-flame, and reduce leaking out of fire grate rear end.
