Abstract

The utility model relates to a normal-atmosphere water boiler, and in particular to a normal-atmosphere water boiler with a rotary grate, which aims at resolving the weaknesses of the traditional water boiler with a fixed grate that the heat efficiency is low and the honeycomb briquette cannot be combusted. The normal-atmosphere water boiler consists of a boiler body, a hot water outlet pipe, a smoke outlet pipe, a transverse water pipe, a fire pipe, a boiler container, a feeding boiler door, a sewage discharging pipe, a grate, a slag outputting car and a water inlet pipe, and is characterized in that the boiler container is divided into an upper section and a lower section, and the upper section is connected with the lower section through a central fire pipe and a side fire pipe, and the middle part of the grate is provided with a driving rotating shaft that is connected with a hand wheel to be exposed outside the boiler body, and the other end of the grate is provided with an eccentric wheel and is interlocked with a driven rotating shaft through a connecting rod, and the driving rotating shaft and the driven rotating shaft are supported by a shaft sleeve, and the shaft sleeve is provided with a slag discharging blade. Compared with the traditional water boiler with a fixed grate, the normal-atmosphere water boiler with a rotary grate has simple structure, and can combust the honeycomb briquette with poor quality, and can improve the heat efficiency by 10 to 15 percent; the chimney is free from discharging black smoke, and the dust is sealed, thereby being free from polluting the environment, and being applicable to the fields such as the industry, the school and the service industry to provide low-price hot water.

Description

The travel(l)ing grate atmospheric hot-water boiler

Technical field:

The utility model relates to a kind of normal-pressure hot-water boiler, particularly a kind of travel(l)ing grate atmospheric hot-water boiler.

Background technology:

Normal-pressure hot-water boiler is widely used in a kind of thermal hardware of industry, school, service industry, and forms such as fuel oil, combustion gas, fire coal are arranged, though preceding two kinds of environmentally-friendly sanitaries, equipment, fuel costliness, less employing.Drawbacks such as coal combustion equipment, fuel are cheap, but mostly are furnace cupola, and the easy slagging scorification of lump coal, burning are insufficient, chimney over-emitting black exhaust, dust from flying, contaminated environment, kettleman's labour intensity are big.Honeycomb briquette can adopt colm to make, and venting capability is good, and it is more abundant to burn, but can not make the fuel of furnace cupola, mainly is that honeycomb briquette is glued with the yellow mud, needs often slagging-off, otherwise can influence the gas permeability and the thermal efficiency.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned coal-fired hot-water boiler weak point and travel(l)ing grate atmospheric hot-water boiler that the higher honeycomb briquette that can burn of a kind of thermal efficiency is provided.

The utility model is by square or cylindrical furnace, the hot water outlet pipe, smoke outlet tube, horizontal water tube, fire tube, flue, the charging fire door, blow-off pipe, fire grate, the dolly of slagging tap, water inlet pipe is formed, it is characterized in that flue is cylindrically to be divided into two sections, it is upper furnace, lower furnace, connect by fire tube, it is through type that the internal layer fire tube has the 6-12 root, outer fire tube has the 10-28 root for being close to the side formula, upper furnace has the ash discharge fire door, lower furnace has the charging fire door, one is active rotating shaft in the middle of the fire grate, be connected with the handwheel exposure outside body of heater, end is fixed with eccentric wheel in addition, and by connecting rod and many driven spindle interlocks, active rotating shaft and driven spindle are by sleeve supporting, dreg discharging knife is arranged on it, and the dreg discharging knife spacing is 2-5 centimetre.

The utility model is divided into lower furnace with the combustion chamber, and upper furnace is the convection section heat exchange, and lower furnace is the radiant section heat exchange; Adopt travel(l)ing grate regularly to remove the gred, the honeycomb briquette of incendivity poor quality reduces coal-fired cost.The utility model is simple in structure, compare with traditional furnace cupola, it is more abundant to burn, and can improve thermal efficiency 10-15%, not over-emitting black exhaust, dust sealing of chimney, free from environmental pollution, can alleviate kettleman's labour intensity, be fit to the usefulness that industry, school, service industry etc. provide cheap hot water.

The specific embodiment:

Fig. 1 is a travel(l)ing grate atmospheric hot-water boiler structural representation.Square furnace 1 is by heat-insulation layer parcel, in columniform combustion chamber flue is arranged, flue is divided into two sections, be upper furnace 5, lower furnace 8, connect that the internal layer of fire tube 7 has 9 to be through type by fire tube 7, outer fire tube has 19 for being close to the side formula, and the cross-sectional distribution of fire tube as shown in Figure 2.Between flue and the body of heater and horizontal water tube 4 fillings be heat carrier water, cold water is entered by body of heater bottom water inlet pipe 13, hot water is discharged by the hot water outlet pipe 2 at body of heater top, the precipitation foul in the water can be regularly by blow-off pipe 10 discharges of body of heater bottom.

Lower furnace 8 has honeycomb briquette charging fire door 9, the high temperature gas flow that burning produces is based on heat radiation, and high temperature gas flow rises to upper furnace 5 by the ectonexine fire tube, and carries out the convection type heat exchange by furnace wall, horizontal water tube, with the cold water heating, waste gas is discharged outside the body of heater by smoke outlet tube 3.The dust that high temperature gas flow is carried secretly in heat exchange gradually cooling stopped by horizontal water tube and on being deposited on the lower furnace dividing plate, can regularly discharge by ash discharge fire door 6, so smoke outlet tube 3 can over-emitting black exhaust and dust, not only environmental protection but also health.

Fire grate 11 is arranged at the bottom of lower furnace 8, and the structure of fire grate as shown in Figure 3; Fig. 4 is a fire grate B-B profile, it is made up of the active rotating shaft 14 and the six roots of sensation driven spindle 15 of equidistant arrangement, active rotating shaft is connected with handwheel 18, exposure is outside body of heater, can make 360 degree both forward and reverse directions and rotate, the other end of active rotating shaft is connected with eccentric wheel 20, and by connecting rod 19 and driven spindle 15 interlocks, active rotating shaft and driven spindle are by axle sleeve 16 supportings, and the fire grate link gear as shown in Figure 4.Numerous dreg discharging knifes 17 are arranged on active rotating shaft and the driven spindle, the cutter spacing is 2.5 centimetres, blade is the T font, give prominence to outside rotating shaft, can the broken honeycomb briquette remains of completing combustion when rotating shaft drives blade and rotates, make on its dolly 12 of slagging tap that is scattered in bottom of furnace body, slag removal is to carry out under sealing state, dust can not overflow outside the body of heater, not only environmental protection but also health.Can add air-introduced machine under the fire grate and suitably control furnace temperature.
