As Fig. 1-shown in Figure 4, a kind of smokeless and dustless coal-fired furnace, comprise a furnace outer body 2, fire grate 3, conveying device and power set, conveying device is made up of rotating shaft 18, bearing 10 and the bearing cap (14,23) of hopper 9, base 16, carrier pipe 17, band flight, and described furnace outer body is established back taper stove endosome 4 in 2 tops; Sidewall is established 6 sealing-ins of some air vent 5, one barrel masts outside stove endosome 4 around stove endosome 4 upper ends, and forms annular compartment 7; Fire grate 3 is erected at barrel mast 6 and 2 liang of tops of furnace outer body; The carrier pipe outlet 32 of carrier pipe 17 left ends is arranged in furnace outer body 2, and fixedly connected with stove endosome 4 lower port that cooperate; Furnace outer body 2 left sides are provided with air main 1, secondary airduct 24 and have the scum pipe 27 of hermatic door 26, and scum pipe 27 all is connected with air main 1 with secondary airduct 24 and communicates, 27 liang of right-hand members of air main 1 and scum pipe penetrate furnace outer body 2 respectively and join with barrel mast 4 sidewalls, and connect annular compartment 7; A upper shed groove 28 is established in furnace outer body 2 preceding bottoms, and upper shed groove sidewall 29 tops are higher than furnace outer body front upper part sidewall 36 bottoms.
Be arranged with the opposite two parts flight of the hand of spiral (19a, 19b) in the described rotating shaft 18, vacancy between two parts flight (19a, 19b) the inner is positioned at carrier pipe and exports 32 belows, be arranged with ring washer plate 15 in the rotating shaft 18 of flight (19a, 19b) outer end, carrier pipe 17 two ends are positioned on ring washer plate 15 bottom outward and have discharge gate 34, hopper 9 connects in carrier pipe 17 right part upside carrier pipe imports 33, and rotating shaft 18 right-hand members stretch out bearing cap 14 and are connected with power set.Can be when its rotating shaft is rotated with fire coal from the output of the vacancy position between two flight the inners, can be in trend back taper stove endosome coal continuously automatically from bottom to top, reliability is good.
Bearing 10 on described rotating shaft 18 two ends is a taper roll bearing, and a deep groove ball bearing 35 is also established in the taper roll bearing inboard of rotating shaft 18 right-hand members.It is strong that taper roll bearing bears axial force, can better adapt to rotating shaft bigger axial reaction force in the process of delivering coal.In addition, because the axial reaction force that the taper roll bearing on the rotating shaft right-hand member bears is big especially, its easier wearing and tearing earlier, the formation radial clearance increases, cause the shaft centerline swing, and after this end taper roll bearing inboard added deep groove ball bearing, it is stable that shaft centerline just can keep.Make that the pay-off performance is more reliable and more stable.
But be respectively equipped with air register 25 on described air main 1 and the secondary airduct 24.Its easier pressure combustion air speed and flow of making reaches perfect condition, makes coal-fired red-hot and completing combustion under high temperature and oxygen enrichment state, and flame can be pure as burning torch, smokeless and dust free, environmental protection and energy saving.
The outside is connected on the support 20 at the bottom of described carrier pipe 17 left ends, and support 20 rear and front ends are fixed on furnace outer body 2 sidewalls.This is simple in structure, installs easily.In addition, the outside is connected on the base 16 at the bottom of carrier pipe 17 right-hand members.
The cross section of described furnace outer body 2, stove endosome 4 and barrel mast 6 is rectangle, and it is easier that the sheet material that its rectangular configuration makes the stove endosome have suitable thickness is processed.And furnace outer body 2 can be made as rectangle or cylindrical shape.
A swash plate 21 is established in the bottom in the described furnace outer body, and is low early and high after under being positioned at carrier pipe 17.This swash plate 21 can be accepted the lime-ash that falls from fire grate 3, and lime-ash can make deslagging more convenient along the inclined-plane slippage to upper shed groove place.In addition, a ring seat circle 8 is fixed on the furnace outer body top, and it is used for fixedlyed connected by the outer cylinder body of hot-water line and blast pipe with outside being provided with.
Spout hole that described upper shed groove sidewall 29 fronts are respectively equipped with up and down 30 and have the osculum 31 of end cap, its spout hole 30 is risen with outer end, 17 end of carrier pipe and is maintained an equal level, make that furnace outer body 2 inner bottom parts add water after, the water surface is remained in the certain altitude.Water in the furnace outer body inner bottom part can be by osculum 31 convenient discharges.
The rotating shaft 18 that has two parts flight in the utility model is located in the carrier pipe 17 by two bearings 10 and two bearings lid (14,23).Two bearings lid (14,23) is fixedly connected on carrier pipe 17 outer ends by fixed screw 22.Bearing cap 14 is stretched out in rotating shaft 18 right outer ends, is connected with power set by shaft coupling 11, and power set are made up of decelerator 12 and motor 13, and decelerator 12 and motor 13 also are installed on the base 16.
The utility model can be on the top of furnace outer body 2 cooperates to connect by ring seat circle 8 and variously is provided with the outer cylinder body that is subjected to hot-water line, gas flue and blast pipe, thereby constitutes firing equipments such as various Industrial Stoves, boiler, water heater.It can be automatically coal continuously, be suitable for bituminous coal, fine coal, particle coal and bio-fuel burning.
During use, furnace outer body bottom Jia Shui, the furnace outer body bottom is sealed by the water surface, and fire coal is imported from stove endosome lower port from bottom to top by conveying device, and the red-hot all the time burning of coal-fired top layer no longer produces thick smoke during coal.Combustion air is combustion-supporting from the sidewall air vent output of stove endosome upper end through annular compartment by air main and scum pipe; It is further combustion-supporting constantly upwards to export combustion air by secondary airduct from the fire grate below in addition, and the coal-fired combustion-supporting air is very sufficient, and ignition temperature is very high, and the dry residue that lands from the fire grate gap will fall into the water precipitation of bottom in the furnace outer body and no longer wave.Therefore, the present invention can make that fired coal combustion is abundant, ignition temperature is high, reaches smokeless and dust free and environmental protection and energy saving.
What should be understood that is: the foregoing description is just to explanation of the present utility model, and any innovation and creation that do not exceed in the utility model connotation scope all fall within the protection domain of the present utility model.
