Abstract
The invention discloses a combustion device of a tempering furnace. The combustion device comprises a burner and a hearth, wherein the top of the hearth is provided with circulating fans; the rotating directions of impellers of two adjacent circulating fans are reverse; the burner is installed on the furnace wall, symmetrically arranged, and the combustion gas generated by the burner is stirred by the circulating fan to heat workpieces; a plurality of circulating fans are uniformly distributed in the middle above the hearth; each circulating fan is provided with an air shield; the air shield can well cover the workpieces by size; and the burner is above the air shield. For the combustion device of a tempering furnace with the special structure, the burner is above the air shield; the high temperature gas at the outlet of the burner is not in direct contact with the workpieces; the phenomenon of local high temperature is avoided; the workpieces are guaranteed to be heated uniformly and the intrinsic properties of the workpieces are improved; and the yield of products is improved. Meanwhile, the circulating fans forcedly stir and circulate the gas in the furnace, and the air shield acts to form a plurality of cycles, thus ensuring uniform temperature distribution of gas in the furnace.
Description
Technical field
The present invention relates to the industrial furnace field, especially relate to a kind of tempering stove that is used for various combustion gas heating.
Background technology
Tempering temperature homogeneity directly influenced the internal performance quality of workpiece.Existing coal gas tempering stove all adopts high combustion rate burner, and coal gas mixes afterfire in the burner chamber, and high-speed gas flame produces the intensive transmission of heat by convection from the ejection of burner spout in stove, add the violent stirring of a large amount of gases, makes the interior temperature of stove reach even.This firing system inevitably has flame directly to touch workpiece, causes localized hyperthermia, poor temperature uniformity, and simultaneously, noise is big.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of tempering stove combustion unit at problems of the prior art, its objective is that the temperature that guarantees in the stove is even, avoid flame directly to touch workpiece, no localized hyperthermia, guarantee that workpiece is heated evenly, improve the internal performance of workpiece, improve product percent of pass.
Technical scheme of the present invention is this kind tempering stove combustion unit, comprises burner and burner hearth, and roof of the furnace is provided with the recirculating air device, and burner is installed on the furnace wall, and is symmetrically distributed, and the combustion gases that burner generates heat workpiece by the stirring of recirculating air device.
Described recirculating air device be mid-way above burner hearth along a plurality of recirculation blowers of length direction uniform distribution of rectangle stove, each recirculation blower has a fan housing, the size of fan housing be able to cover workpiece.
If stove is a ring furnace, then described recirculating air device be mid-way above burner hearth along a plurality of recirculation blowers of circumferential uniform distribution of annular stove, each recirculation blower has a fan housing, the size of fan housing be able to cover workpiece.
The direction of rotation of the impeller of described adjacent two recirculation blowers.
The position of described burner is in the top of fan housing.
A kind of tempering stove combustion unit with above-mentioned special construction has the following advantages:
1, the burner of this kind tempering stove combustion unit is in fan housing top, and the high-temperature gas in burner exit is direct contact workpiece not, has avoided the phenomenon of localized hyperthermia, guarantees that workpiece is heated evenly, and improves the internal performance of workpiece, the raising product percent of pass.
2, the recirculation blower of this kind tempering stove combustion unit stirs stove internal combustion gas, furnace gas is forced to stir circulation, effect by fan housing, form a plurality of circulations, furnace gas temperature is evenly distributed, workpiece is bathed in the furnace gas, under the forced-flow of gas, conducts heat with air-flow.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present invention.
Fig. 2: the structural representation of recirculation blower.
Fig. 3: recirculation blower scheme of installation
In Fig. 1,1: burner; 2: recirculation blower; 3: fan housing; 4: workpiece.
Embodiment
By the combination of structure shown in Fig. 1-3 as can be known, this kind tempering stove combustion unit is made up of burner 1, recirculation blower 2 and fan housing 3.Recirculation blower 2 is installed in the furnace roof mid-way, and the wheel rotation direction of adjacent recirculation blower 2 is opposite, helps the stirring of air-flow; Fan housing 3 is suspended on the below of draught fan impeller 2 by suspension rod.The combustion gases that burner 1 generates form and reflux by the stirring of recirculation blower 2, are gas flow direction shown in arrow in the Figure of description 1, form transmission of heat by convection with workpiece 4.Owing in the stove a plurality of recirculation blowers 2 are set, furnace gas to be forced to stir circulation, furnace gas temperature is evenly distributed, and workpiece 4 is bathed in the furnace gas, under the forced-flow of gas, conducts heat with air-flow.
