Abstract

The utility model relates to a multifunctional energy-saving life boiler, belonging to the technical field of the normal-pressure boiler. A hollow cavity at the inner part of a casing body filled with the water is communicated with a plurality of boiler furnaces which are arranged in the definite distance, the periphery of the boiler furnaces is made into the wave shape, and the contact area of the flame is added. A combustion chamber comprises a water casing and a water pipe grate which is communicated with the water casing. The lower side of the water pipe grate is also provided with a slag removal grate, and the inner part of a chimney is provided with a steam superheating heater. The periphery of the boiler is sheathed with an auxiliary water tank which is beneficial for preheating the water in the boiler, is also provided with a plurality of metal cupboards for drying, cooking, washing bowls and washing clothes, and the waste heat of the boiler can be used substantially.

Description

Multifunction energy-saving boiler

The utility model relates to a kind of multi-functional boiler for domestic that can supply with steam and hot water.

Boiler for domestic generally has only a flue at present, and fire grate also mostly is the cast iron manufacturing, and the heat that boiler casing distributes is not absorbed and used, and the thermal efficiency is not high, and the boiler function is comparatively single; Can't air blast during power failure, the influence burning.

The purpose of this utility model provides a kind of flue, fire grate can fully contact furnace flame, can produce part water-gas during fired coal combustion, the boiler casing waste heat energy is fully utilized and does not need the energy-saving multifunction normal pressure boiler for domestic of air blast.

The purpose of this utility model is achieved in that an interlayer cylindrical shell with headroom (1) as boiler shell (2), and housing has flue tube (12), steam pipe (13) to pass, and its bottom is deashing chamber (3); A plurality of flues that keep at a certain distance away (4) are housed in the housing, this flue is made up of concentric multi-turn cylinder type hollow annulus, the side of annulus is a waveform, each encloses has short tube to be communicated with between hollow ring, and the outermost of each hollow ring, interior two circles also have short tube to be communicated with the inner casing of boiler shell respectively; The flue below is provided with combustion chamber (15), this combustion chamber is the cylinder type hollow housing with arch top--water hull (5), it is communicated with boiler shell by short tube (10), (11), the water pipe furnace grate (6) that communicates with itself is housed in the water hull (5), along having a groove on the axis direction, steam jet (7) is equipped with in the top of water pipe furnace grate (6) to every pipe of water pipe furnace grate (6) at it; Scarfing cinder fire grate (8) is equipped with in the top of the bottom deashing chamber of boiler shell; Boiler chimney (16) is equipped with steam superheater (17), and the wall of superheater is also made waveform, and the chimney bottom is connected with one section short tube (18); A plurality of metal cupboards that the shell higher slice of boiler shell (2) is adorned secondary water tank (9) and is used for drying, boiling, washes the dishes, does washing.The critical piece flue of boiler, combustion chamber, fire grate, steam superheater etc. are all connected by connector, and are detachable.

Below in conjunction with accompanying drawing structure of the present utility model and operation principle are further specified.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the flue tube structure schematic diagram.

Fig. 3 is the steam superheater schematic diagram that is loaded in the chimney.

Fig. 4 is the water pipe organigram of water pipe furnace grate.

In Fig. 1, cold water enters boiler shell (2) after entering secondary water tank (9) by water inlet pipe (19), enters water hull (5), water pipe furnace grate (6) and flue (4) immediately again.Coal cinder is sent into the interior combustion chamber of water hull (5) by feeding mouth (20).When lighting a fire first, temporarily send into a small amount of blast from feeding mouth (20), the coal-fired flame of lighting is sent the below of water hull (5), flame rises by the multilayer flue around water hull (5) again; After producing steam, the steam pressure of steam pipe (7) ejection can replace external wind pressure used when lighting a fire.Steam is sprayed on the scorching hot coal cinder, also can produce water-gas, improves temperature in the stove.Because the annulus side of flue is a waveform, has strengthened the contact area of flame and flue.The flue gas that flue tube (12) is discharged enters chimney (16), is combined in steam superheater (17) on the chimney with the chimney UTILIZATION OF VESIDUAL HEAT IN, and the steam superheater wall is also made waveform, has further increased the flue gas contact area again.Chimney bottom is connected to one section opening short tube (18), plays unimpeded smoke evacuation effect.Each bar water pipe of water pipe furnace grate (6) has a groove along axis direction, and having overcome water pipe furnace grate in the prior art, to bear the thermic load ability relatively poor and be prone to the drawback of axial crack.The scarfing cinder fire grate (8) of water pipe furnace grate below can connect the fire coal that falls the holder afterflame, plays bilayer and returns the burning effect.Boiler casing has been installed multi-layer multi metal cabinet, and they are: drying cupboard (21), boil cabinet (22), and steamer (23), dish washing cupboard (24), laundry cabinet (25), these cupboards can absorb the body of heater heat radiation.The boiler bottom penetrates housing coal and firewood furnace flue tube (14) also is housed, and the flue gas of coal and firewood furnace can feed thus in the boiler and utilize once more.

The utility model has maximally utilised fuel thermal energy, does not need air blast, has multiple function.

Claims

1, a kind of life normal pressure multi-function boiler, comprise burner hearth, double-deck stove row, water tank, liquid level gauge, the steam superheating pipe, kitchen range etc., it is characterized in that: water tank is an interlayer cylindrical shell with headroom (1) a--boiler shell (2), housing has flue tube (12), steam pipe (13) passes, a plurality of flues that keep at a certain distance away (4) are housed in the housing, this flue is made up of concentric multi-turn cylinder type hollow annulus, each encloses has short tube to be communicated with between hollow ring, and the outermost of each hollow ring, interior two circles all have short tube to be communicated with the inner casing of boiler shell; The combustion chamber (15) that the flue below is provided with, for having the cylinder type hollow housing at arch top--water hull (5), it is communicated with boiler shell by short tube (10), (11); The water pipe furnace grate (6) that communicates with itself is housed in the water hull (5), and steam jet (7) is equipped with in the top of water pipe furnace grate (6); Water pipe furnace grate (6) is communicated with water hull (5); Boiler chimney (16) is equipped with steam superheater (17), and the chimney bottom is connected with one section short tube (18); The shell higher slice of boiler shell (2) is equipped with a plurality of metal cupboards that are used for drying, boiling, wash the dishes, do washing.
