Abstract
The invention discloses a coal furnace. Due to the fact that a flow guiding cavity and a rotational flow combustion cavity are formed in a traditional coal furnace, disturbance and rotational flow of gas are achieved through a screw-type rotational flow air cylinder, and the flow speed and the heat conductivity of the gas are accelerated. Therefore, the combustion rate of fuel inside the coal furnace is increased, the generation of harmful gas like carbon monoxide is reduced, meanwhile, the heating efficiency of the coal furnace is improved, and the coal furnace has good social benefits.

Described diversion cavity comprises kuppe and drain pan, described kuppe is the megaphone-shaped structure that a flaring is opened, on the cone inwall, the edge larger from the cone diameter is symmetrically arranged with the curve tab sheet of some rules to the less edge of cone diameter, described tabs bending direction is all consistent; Described drain pan is the pot shape cover body that diameter is identical with kuppe expansion diameter, and described kuppe is connected with two edge seals of drain pan by equal diameters, and described drain pan bottom is connected with air inlet pipe;
Described combustion chamber comprises that down-draft cylinder and coal hold bucket, and described down-draft cylinder is the flaring structure, and the less end of described down-draft cylinder diameter and diversion cavity sealing are communicated with, and the larger end of described down-draft cylinder diameter and coal hold bucket and is communicated with.
As further innovation of the present invention, described coal stove bottom also is provided with the described through hole of through hole and air inlet pipe is communicated with, and described through hole is also supporting a seal cover.
As further innovation of the present invention, in the middle of described kuppe and drain pan, be separated with sieve plate.
As further innovation of the present invention, described down-draft cylinder inwall is provided with the curved protrusion sheet of some rules, and described curved surface bending direction is all consistent, and position, described curved surface interval also is provided with some bulbous protrusion.
As further innovation of the present invention, described kuppe bottom is processed with breach, and described breach runs through flame-retardant layer and coal stove outer covering and outside the connection, and described breach is also supporting a seal cover.
Beneficial effect
Beneficial effect of the present invention is:
1. the present invention is by arranging diversion cavity and swirl flow combustion chamber in traditional coal stove, by a screw type eddy flow air duct, realize disturbance and the eddy flow of gas, accelerate flow velocity and the conductivity of heat of gas, thereby the combustion rate of fuel in the increase coal stove, reduce the generation of the pernicious gases such as carbon monoxide, also improve simultaneously the efficiency of heating surface of coal stove, had good social benefit.
2. the present invention is by an ash exhauster is set in vertical base, and than the ash exhauster of traditional coal stove, ash exhauster of the present invention is because of its vertical characteristic, and ash discharge is more thorough, and the assurance air channel can not stopped up by coal ash, improves the efficiency of burning.
3. the present invention, by sieve plate and ash-hole are set at middle part, has further facilitated the deashing work of coal stove, also prevents that the coal stove bottom that drops to of coal fuel bulk from blocking air channel simultaneously, brings obstruction for the completing combustion of fuel in coal stove.

The specific embodiment
Below in conjunction with accompanying drawing, be described further
As shown in Fig. 1 ~ 4: a kind of coal stove, comprise shell, flame-retardant layer, combustion chamber, described combustion chamber is arranged in shell by flame-retardant layer, and described coal stove also comprises diversion cavity, air inlet pipe 1, and described air inlet pipe 1 is arranged on the coal stove bottom and the described combustion chamber of diversion cavity connection is arranged on diversion cavity top and connection, described diversion cavity, air inlet pipe 1, combustion chamber are arranged in shell, with the gap-fill of shell, flame-retardant layer are arranged;
Described diversion cavity comprises kuppe 9 and drain pan 4, described kuppe 9 is the megaphone-shaped structure that a flaring is opened, on the cone inwall, the edge larger from the cone diameter is symmetrically arranged with the curve tab sheet of some rules to the less edge of cone diameter, described curved surface bending direction is all consistent; Described drain pan 4 is the pot shape cover body that diameter is identical with kuppe 9 expansion diameters, and described kuppe 9 is connected with two edge seals of drain pan 4 by equal diameters, and described drain pan 4 bottoms are connected with air inlet pipe 1;
Described combustion chamber comprises that down-draft cylinder 6 and coal hold bucket 7, and described down-draft cylinder 6 is the flaring structure, and the less end of described down-draft cylinder 6 diameters and diversion cavity sealing are communicated with, and the larger end of described down-draft cylinder 6 diameters and coal hold bucket 7 and is communicated with;
At coal, holding bucket 7 top is provided with pallet 8 and places all kinds of heating vessels;
As further innovation of the present invention, described coal stove bottom also is provided with the described through hole 3 of through hole 3 and air inlet pipe 1 is communicated with, and described through hole 3 is also supporting a seal cover 2;
