Abstract

The utility model of a water-supply furnace relates to a combustion furnace supplying hot air or hot water, and comprises an outer shell, a hearth in the shell, a smoke flue communicated with smoke outlet of hearth, and a circulating pipe. The utility model designs the inner cavity of the hearth into a beaker-shaped to fully absorb the heat that is generated from burning and can be fully exchanged through continuously updating the structure of the circulating pipe; besides, the problem that the outflow water is uneven cold and heat is avoided. By adding a thermal insulation tank at the top of the heath, the utility model makes the heat of the smoke flue recycled and the environmental pollution reduced, thereby, supplying a novel water-supply furnace that makes the heat energy fully absorbed and has high efficiency and energy saving property.

Description

Coal-fired water supply stove

Technical field:

The coal-fired water supply stove of the utility model relates to a kind of combustion furnace that hot blast or hot water are provided, and particularly relates to a kind of heat transfer efficiency height, the fire coal water supply stove of energy savings.

Prior art:

Existing coal-fired water supply stove is because the reasonable inadequately most of heat of flue tube structure design is directly drained from the smoke pipe pipeline, and the heat energy that causes the flue internal combustion to produce can not fully absorb, and not only wasted resource but also contaminated environment.

For avoiding the deficiencies in the prior art part the utility model that a kind of novel coal water supply stove is provided, it can make heat energy fully absorb, have energy-efficient characteristics.

Summary of the invention:

The utility model is realized by following technical measures, it comprises shell, place the flue in the shell, flue that is communicated with the flue outlet flue and circulating line are formed, the inner chamber its underpart that it is characterized in that flue is the bullet that an opening makes progress, top is a bullet that Open Side Down, two parts form the flue inner chamber of a beaker shape up and down, the bottom of flue inner chamber is the stove stratum reticulare, the bottom of stove stratum reticulare is provided with end ventilating duct, the two sides of stove have charge door and air inlet, the insulation pond is equipped with at the top of flue, the top of flue is provided with more than one flue, flue passes in the insulation pond and extends to outside the insulation pond, be provided with circulation pipe in the flue inner chamber, the circulation pipe import is connected with the insulation pond, and outlet is outside flue stretches out stove.

The top in insulation described in the utility model pond is provided with collection chamber, and the cigarette that collection chamber is discharged flue focuses in the collection chamber, and the chimney by gas collection chamber top is discharged to outside the stove again.

Charge door described in the utility model passes flue and communicates with the flue inner chamber, and the charge door position exceeds plane, stove stratum reticulare place, and air inlet passes flue and communicates with end ventilating duct.

Circulating line described in the utility model is crooked along the vertical direction snake bend.

Its upper end, insulation described in the utility model pond is provided with water inlet and lack of water water inlet, and the bottom is provided with delivery port, and delivery port links to each other with circulation pipe import in the flue.

The utility model can be used as the water supply stove, also can be used as the air feed stove.

The utility model is by the improvement to existing flue tube structure, the heat that makes burning produce fully absorbs, make not only that by renewal heat is fully exchanged to the circulation pipe structure, but also avoided water outlet problem uneven in temperature, by add the insulation pond at the flue top, the heat that makes flue have also can be recycled, and has reduced environmental pollution.

Below in conjunction with accompanying drawing the utility model is further specified.

Specific embodiment:

As accompanying drawing 1, the utility model is by shell 1 shown in accompanying drawing 2 and the accompanying drawing 3, place the flue 2 in the shell, flue 3 that is communicated with the flue outlet flue and circulating line 4 are formed, the inner chamber its underpart that it is characterized in that flue is the bullet 4 that an opening makes progress, top is a bullet that Open Side Down 5, two parts form the inner chamber 6 of a beaker shape up and down, the bottom of flue inner chamber is a stove stratum reticulare 7, the bottom of stove stratum reticulare is provided with end ventilating duct 8, end ventilating duct is a bullet, ventilating duct double as cinder pond, the end, flue is encapsulated in the shell 1, the two sides of coal-fired water supply stove have charge door 9 and air inlet 10, charge door and air inlet are oblong channel, charge door 9 passes flue and communicates with the flue inner chamber, the charge door position exceeds plan-position, fire bars net place, air inlet 10 passes flue and communicates with end ventilating duct, insulation pond 11 is equipped with at the top of flue, the bottom surface in insulation pond is as the end face of flue shell, make shell and insulation pond be integral, insulation pond and shell are square casing, the top of flue is provided with 4 flues 3, flue focuses on cigarette in the collection chamber 12 that is arranged on insulation top, pond, by smoke evacuation tube 13 cigarette is discharged to outside the stove again.Be provided with circulation pipe in the flue inner chamber, the circulation pipe import is connected with the insulation pond, and outlet is outside flue stretches out stove.

Its upper end, the utility model insulation pond is provided with water inlet 14 and lack of water water inlet 15, and the bottom is provided with delivery port 16, and delivery port links to each other with circulation pipe import in the flue.

The utility model circulation pipe is a snake bend as shown in Figure 4, and coiled pipe is crooked along the vertical direction, makes that not only heat exchange is abundant, also makes to be heated evenly, and avoids occurring water temperature phenomenon uneven in temperature, and the both sides of coiled pipe are fixing with lattice framing 17.
