Abstract
The utility model discloses a steel hearth of a coal furnace. The middle-lower portion of the steel hearth of the coal furnace is a cylindrical steel pipe, the upper portion of the steel hearth is an inverted horn-shaped steel pipe, the middle-upper portion of the inverted horn-shaped steel pipe is provided with a circle of triangular gaps, the position of each triangular gap is welded and plugged by using a triangular steel plate. The steel hearth of the coal furnace has the advantages that the hearth is made of steel and is firm and durable, the disadvantage that a heart built by using mud or a thermal insulation material easily cracks and often maintenance trouble are avoided, the heat radiation is quick, and coal is saved; the upper portion of the heath is inverted horn-shaped, so that smoke and fire arising in the hearth can naturally, smoothly and evenly disperse along an inverted horn-shaped arc, and the cooker bottom can be heated evenly; the steel hearth is simple in structure and easy to manufacture.
Description
Technical field
The utility model relates to a kind of Coal stove chamber, particularly a kind of coal stove steel burner hearth.
Background technology
At present, mostly existing Coal stove chamber is to build by laying bricks or stones and form with mud or insulation material, and its drawback is shaky, easily cracking, and service life is short, builds by laying bricks or stones and wastes time and energy simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of coal stove steel burner hearth of durable, Homogeneouslly-radiating.
Technical solution adopted in the utility model is, this coal stove steel burner hearth, burner hearth middle and lower part is steel cylindrical tube, top is inverted tubaeform steel pipe, inverted tubaeform steel pipe middle and upper part is provided with a circle triangle gap, and each triangle opening position is by a triangular steel plate welding shutoff.
Owing to having taked technique scheme, therefore the utlity model has following advantage: the one, burner hearth is done with steel, not only durable, avoid building easily drawback and the frequent trouble of safeguarding of cracking of burner hearth by laying bricks or stones with mud or insulation material, and rapid heat dissipation, economize coal.The 2nd, upper furnace is inverted tubaeform, be beneficial to burner hearth rise pyrotechnics natural, smooth and easy along the arc of falling loudspeaker, scatter uniformly, kitchen range bottom even is heated.The 3rd, simple in structure, be easy to manufacture.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the side top perspective schematic diagram of the utility model in body of heater;
Fig. 2 is the outer schematic perspective view of looking of the present utility model.
Detailed description of the invention
Embodiment 1, as depicted in figs. 1 and 2, this coal stove steel burner hearth, burner hearth middle and lower part is steel cylindrical tube 1, top is inverted tubaeform steel pipe 2, and inverted tubaeform steel pipe 2 middle and upper parts are provided with a circle triangle gap 3, and shutoff is welded by a triangular steel plate 4 by each triangle gap 3 place.Why a circle triangle gap 3 is established in inverted tubaeform steel pipe 2 middle and upper parts, is because this steel burner hearth is made up of a rectangular steel plates, offers a circle triangle gap 3, just can make upper furnace be inverted tubaeform, material-saving saving of labor like this.
Embodiment 2, coal stove steel burner hearth as described in Example 1, inverted tubaeform steel pipe 2 is positioned at the part at fire door place and offers charging aperture 5.
