Abstract

The utility model provides an all back fire stove with vertical fire grate, which consists of a plurality of parts of an upper fire grate, a lower fire grate, a feeding opening, an air inlet, a furnace, a combustion chamber, a dust collecting chamber and a smoke flue, and is characterized in that an upwardly inclined angle ranging from 30 degrees to 50 degrees is positioned between the upper fire grate and a bottom plane of the stove. The upper fire grate is vertically welded with a combination of vertical columns. The feeding opening and the fire grate are inclined in the same direction. The fence type air inlet is arranged under the feeding opening, and provided with an air flow regulating plate. The height of the upper edge of the air inlet is less than that of a highest point of the upper fire grate. A smoke flue opening is arranged under the upper fire grate and the highest point of the fire grate. The back fire stove makes use of natural absorption force in the process of the combustion of the coal, solves the problem of the arrangement of high and coarse chimney for the traditional back fire stoves, improves the combustion condition of the stoves, enhances the heating capacity of the stove, and can be used for the production of the pressure-free stoves of the civil soil heating stoves or tea stoves etc.

Description

A kind of vertical fire grate all back fire stove

One, technical field:

The utility model relates to a kind of coal burning water heating stove, and specifically a kind of vertical fire grate is all-trans and burns the type of furnace of burning structure.

Two, background technology:

Its fire grate of all back fire stove is several water pipes side by side in the market, its oblique angle is about about the 8-12 degree, air inlet is above fire grate, pyrotechnics is passed down through fire grate, outlet flue is below fire grate, and there is a very strong natural climbing power high-temperature region that coal when burning forms, and this power has greatly hindered anti-burning kiln gas and flowed round about.Cause the obvious deficiency of flue gas nature draft, existing all back fire stove with just burn stove and compare, have ignition difficulties, slow, shortcomings such as burning velocity is slow, heating load deficiency on fire, for improving the draft of flue gas, usually take overstriking, add chimney stack, measures such as chimney turns round are avoided in installation, have both strengthened cost, all restrictions when causing installation to the user again.

Three, summary of the invention:

The purpose of this utility model is to provide a kind of a kind of vertical fire grate all back fire stove of being convenient to install and use that can improve the draft of coal stove nature significantly.

The utility model is achieved in that

Should instead burn stove is made up of last lower fire grating, charging aperture, air inlet, burner hearth, combustion chamber, ash accumulating chamber, several parts of flue.Being burner hearth above the upper fire-grating, being provided with charging aperture, air inlet, is the combustion chamber between the last lower fire grating, lower fire grating bottom is an ash accumulating chamber, the tilt angle on upper fire-grating and furnace bottom plane is the 30-50 degree, is welded with one group of column on the upper fire-grating vertical direction, the equidirectional inclination of charging aperture and upper fire-grating, air inlet is located at the charging aperture below, be fence type, and air-flow plate is arranged, the air inlet upper limb should be lower than the peak of upper fire-grating, floss hole is located at the below of upper fire-grating, fire grate peak place.

The combustion furnace that adopts the utility model to produce, because with the fire grate wide-angle tilt, outlet flue is higher than air inlet, well utilized the natural suction in the flame mechanism, solve classical inverse burning stove and depended merely on stack draught, need to be equipped with the problem of lusty chimney, improved the heat capacity of stove, improved the combustion position of stove and accessory.

Four, description of drawings:

The utility model is described in further detail below in conjunction with accompanying drawing:

Accompanying drawing 1 is that a kind of vertical fire grate is all-trans and burns the dim steam stove structural representation of civilian soil;

Accompanying drawing 2 is that a kind of vertical fire grate is all-trans and burns the drinking water boiler structural representation;

Five, the specific embodiment:

As shown in Figure 1, this civilian indigenous heating stove is made up of upper fire-grating 6, lower fire grating 10, charging aperture 5, air inlet 7, burner hearth 4, combustion chamber 9, ash accumulating chamber 11 and flue more than 15 parts.It above the upper fire-grating burner hearth 4, be provided with charging aperture 5 and air inlet 7, it between the last lower fire grating combustion chamber 9, it below the lower fire grating ash accumulating chamber 11, the tilt angle of upper fire-grating and furnace bottom face is 45 degree, low early and high after, on upper fire-grating, vertically be welded with one group of column 8, glide to prevent fuel, charging aperture 5 tilts in the same way with upper fire-grating, air inlet is located at the charging aperture below, is fence type, and anti-coal skids off, and be provided with air-flow plate, the air inlet upper limb should be lower than the peak of upper fire-grating, and floss hole 12 is located at the below of upper fire-grating, fire grate peak place.For make indigenous heating stove get dim, cook dual-purposely, in flue 15, be provided with flue damper 13, have crater 3 at burner hearth 4 tops, mouth 14 is left in the side, and cigarette thorax 1 and stone or metal plate for standing a stove on as a precaution against fire 2 are arranged back between last crater and the side outlet flue.When being used to cook, rotate flue damper 13, will instead burn flue and block, open crater 3, can cook or boil water usefulness.When being used to adopt when dim, close and close crater, open flue damper, stove and accessory enters anti-burning state.

This drinking water boiler is made up of upper fire-grating 6, lower fire grating 10, charging aperture 5, air inlet 7, burner hearth 4, combustion chamber 9, ash accumulating chamber 11 and flue more than 15 parts as shown in Figure 2, position of lower fire grating, charging aperture, burner hearth, combustion chamber, floss hole is identical with the dim steam stove of accompanying drawing 1 civilian soil on it, it is characterized in that having between upper fire-grating peak and the hearth wall exhanst gas outlet 16 that is equivalent to a fire grate gap.

Claims

1, a kind of vertical fire grate all back fire stove, by last lower fire grating, charging aperture, air inlet, burner hearth, the combustion chamber, ash accumulating chamber, several parts of flue are formed, it above the upper fire-grating burner hearth, be provided with charging aperture, air inlet, be the combustion chamber between the last lower fire grating, lower fire grating bottom is an ash accumulating chamber, the tilt angle that it is characterized in that upper fire-grating and furnace bottom face is the 30-50 degree, is welded with one group of column on the upper fire-grating vertical direction, the equidirectional inclination of charging aperture and upper fire-grating, air inlet is located at the charging aperture below, be fence type, and air-flow plate is arranged, the air inlet upper limb should be lower than the peak of upper fire-grating, floss hole is located at the below of upper fire-grating, fire grate peak place.
