Abstract

The utility model relates to a three-purpose small size boiler, belonging to the technical field of a stove combusting coal. The utility model adopts a thermal insulation measure on the periphery of a hearth, causing that combustion in the hearth is more thorough; the time for banking fire is long. A heat absorber is installed above the firebox; a heat absorption calandria is installed in a flue; the direction of water flow is reverse with the direction of fume flow; the heat absorption efficiency is high; a three-way valve is arranged on a water outlet, for controlling flow quantity of water for bath and heating. A grate with thorns can rotate through hand power; the overflow of stove dust can be avoided. The stove can be used for cooking, heating and showering; the utility model is especially suitable for a boutique with somewhat larger area and a small factory.

Description

Three use miniature boiler

The utility model is a kind of three to use miniature boiler, particularly a kind of coal stove that uses for family, small shop, semiworks.

Existing family expenses arcola kind is a lot, is called the domestic heating stove mostly, and its characteristics are generally warmed oneself, cooked and several functions of bathing water.During heating, a duty is do not have to press circulation in the pot, relies on the water temperature in the heat dump to raise, and makes the water convection circulation of heating system reach the purpose of heating.

Though heating stove is more at present, but can also improve aspect the heat exchange effect, in fact the not end temperature difference of the port of export of heat dump and radiator is the bigger the better, the temperature difference height, the corresponding raising of heat pump effect in the pressure-less boiler, the water convection current is strengthened in the pot, can improve heating effect, and the temperature that improves the heat dump head end is easier to, and it is comparatively desirable like this heat dump to be placed on the flame upper end.

Have removing ash of boiler to be one more yet and make us very troublesome thing, disclose fire with poker and make indoor flue dust billowing, after using moulded coal, the pollution of dust has been reduced many, but when the moulded coal coking after, will use stove hook deashing equally, showing does not also have any good way.

The purpose of this utility model is to provide a kind of heat dump on the flame hole and family expenses arcola of clean deashing of being exposed to.

Three usefulness miniature boilers of the present utility model are made up of water inlet pipe 1, endothermic tube row 2, gas vent 5, thermal insulation layer 7, body of heater 11, heat-insulation layer 12, burner hearth 13 and smoke-box 20.Heat dump 10 is installed in the top of burner hearth 13, the endothermic tube row 2 that heat dump water inlet 21 sees through in heat-insulation layer 12 and the smoke-box 20 welds together, the middle part of smoke-box 20 is provided with dividing plate 19, the endothermic tube row 2 of dividing plate 19 both sides sees through dividing plate 19 by connecting leg 3 and welds with the upper and lower case 4 that connects, and the endothermic tube row's 2 in the outside lower linked box 4 welds together with the water inlet pipe 1 that penetrates thermal insulation layer 7.The upper end of heat dump 10 is welded with threeway delivery port 8.Inlay the fire bars support 16 that has fire bars axis hole 30 in the heat-insulation layer 12 of the lower end of burner hearth 13, the axle 31 at fire bars 15 two ends can slide in fire bars axis hole 30, fire bars 15 middle parts are cast with thorn 17, and the fire bars 15 1 end sides of having awl is fixed together by nut with interior side's awl engagement of curved handle 14.

Endothermic tube 10 is that to be welded by the seat of honour 27 and following 28 be one, following seat 28 is by endless tube 23 and connection pipe 22 welding or inverted automobile steering dish-type shapes, the seat of honour 27 of peviform formula is double-deck, in cavity 26 is arranged, have burner 24 in the middle of the bottom at the heat dump seat of honour 27 and along the uniform little burner 25 of radius, have floss hole 18 on 27 tub walls of the seat of honour, flue 18 section type shapes are inverted channel-section steel type shape.

The knot accompanying drawing is described further below:

Fig. 2 is the heat dump of three usefulness miniature boilers;

Fig. 3 is the right view of three usefulness miniature boiler heat dumps;

Fig. 4 is the barbed fire bars schematic diagrames of three usefulness miniature boilers;

Fig. 5 is the vertical view of three usefulness miniature boiler bodies of heater.

Heat sink is made up of endothermic tube row 2 and heat dump two parts, upper and lower case that connects of the endothermic tube row 2 4 middle parts are welded together by some iron pipes, form endothermic tube row 2, and cold water passes through water inlet pipe 1 through the outside Pipe row 2 enters two the pipe rows' 2 in middle part lower linked box 4 again by connecting leg 3, rises along pipe row 2 then Flow into heat dumps by heat dump water inlet 21 to upper linked box 4, the water in the heat dump 10 be heated by Delivery port 8 is by threeway, but inflow radiator or shower. The endothermic tube row 2 of dividing plate 19 both sides Have air vent 5, bleeder pipe 5 can combine as a whole in body of heater, the outside exhaust of single hole.

Adopt the small-sized three-purpose boiler of the utility model to have following features:

1. owing to adopted heat-insulation layer, can deposit the raising fire box temperature, fire-sealing time is lengthened.

2. owing to adopt thermal insulation layer, make the difficult loss of temperature in the flue.

3. the contrary flue gas of the current of pipe heat-extraction system flows to installation in the heat sink, and current are progressively heated, and has improved the thermal efficiency.

4. heat dump is installed in furnace outlet, and having improved circulates in the convection current in the heating system is significantly improved,

Embodiment (see Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5)

The utility model body of heater is the rectangle iron shell, a side panel shove charge kitchen range, and endothermic tube row be installed in the smoke-box of opposite side.

In cooking stove one side, the fire bars below is a sealed iron active set ash storehouse, and ash can be extracted out down for a long time toward outdoor.Heat dump and body of heater table top are welded into one, and fire lid 9 is enclosed in the benzvalene form heat-absorbent surface top of heat dump, can take fire lid 9 away cooking, do boiling water.There is a three-way valve can connect two systems of having a bath and warm oneself respectively on the heat dump, when a system enables, can closes or partly close another system.Dividing plate in the smoke-box can be made by iron plate, and smoke-box is divided into the two parts that are connected by dividing plate, and the flue gas that fire door flows out is in floss hole, smoke-box, the chimney of discharging outside the bodies of heater by exhanst gas outlet 6.Two of endothermic tube rows are fixed on the body of heater with screw checkpost, build at the inner face of smoke and smear expanded perlite as thermal insulation layer, and water inlet is installed in the below of body of heater smoke-box one side, and the gas outlet is an one with the iron pipe string in body of heater, has only an outlet to pick out the body of heater outside.
