Abstract
The utility model relates to the improvement on a salt-bath furnace for heat treatment. The utility model is characterized in that a furnace body is provided with a furnace chamber which has a larger the circumferential diameter than a salt-bath furnace liner, and the circumferential wall of the furnace chamber is provided with a spiral fire guiding duct and a smoke discharging port; the salt-bath furnace liner is in the shape of a metal barrel, and a salt heating and molting device is an oil burner tangentially arranged. Compared with the existing electrode salt-bath furnace, the salt-bath furnace of the utility model has the advantages of low investment, low use cost, simple and convenient replacement and operation, etc. The utility model can avoid the happening of harmful accidents, and is particularly suitable for the heat treatment of small-batch metal.
Description
Utility model relates to a kind of improved thermal treatment salt bath furnace.
Metal heat treatmet such as salt bath quenching, tempering stove adopt the salt bath furnace with submerged electrodes of making thermal source with electrode usually, and it is with electrode discharge salt bath medium one salt to be carried out the melting heating.Yet the electrode discharge heating salt-bath furnace exists: need supporting dedicated transformer, equipment cost is big; Heat-up rate is slow, and energy consumption is big, and fire-resistant salt pond of building by laying bricks or stones (groove) flue is prone to the fused salt seepage and because of leaking the stove of lifting that salt causes, and the electrode wear amount is big, thereby the use cost height; Maintenance is changed complicated; The starting electrode complicated operation; Workpiece falls accidentally and electrode is collided easily generation accident; And overheated for preventing copper bar and electrode handle connection place, need add shortcomings such as water-cooling jacket.
The purpose of utility model is to overcome the deficiency of heated by electrodes salt bath furnace, provides a kind of improved energy consumption low, and heat-up rate is fast, the thermal treatment salt bath furnace that manufacturing cost and use cost is all low.
The utility model purpose realizes that main improvement project is to change electrically heated into fuel Heating.Utility model salt bath furnace specifically, comprise body of heater and be arranged on stove intravital salt pond flue and heating fused salt device, it is characterized in that said body of heater has one than the big burner hearth in salt pond flue week footpath, the burner hearth perisporium is provided with spiral quirk and the smoke outlet of leading, said salt pond flue is the barrel-shaped flue of metal, and said heating fused salt device is the tangential oil fuel burner that is provided with.
The barrel-shaped flue of the said metal of utility model is mainly that to adapt to the burning heating required, and a kind of scheme preferably is mouthful flanging to be set thereon, the flanging effect, and the one, seal fiery road, prevent that flame from being leaked by top; The 2nd, also can play the effect of supporting flue, but also can omit flanging, realize by the ring limit that interruption-forming on burner hearth is inwardly stretched.Said spirrillum is led quirk, mainly is that the flare short circuit of avoiding burning directly runs flue, spirrillum lead quirk can screw on, also can screw under, usually with on the screw for well.The tangential oil fuel burner that is provided with can be above flue, also can be below flue, as long as be oppositely arranged with smoke outlet.These only are the changes of embodiment, and novel protected scope all should be truely used in the unsubstantiality change.For making full use of heat energy, improve the burning heats, also can be provided with a heating flame space between flue bottom and burner hearth bottom, carry out the bottom heating, for preventing bottom flame short circuit, bottom space preferably is provided with the piece of putting of putting piece such as cross structure that can prevent the flame short circuit, both can support the burner with stand courage, can prevent the flame short circuit again.The utility model salt bath furnace melt the salt temperature, can realize by fuel charge and/or the flue opening of regulating burner.
Below in conjunction with a typical embodiment, further specify the utility model structure.
Fig. 1 is an embodiment sectional structure synoptic diagram.
Fig. 2 is the burner hearth bottom structural representation.
Embodiment: referring to accompanying drawing, salt bath furnace body of heater 1 is made up of refractory brick 1.2, thermal insulation layer 1.1. shell 1.3.Have one in the body of heater than the big spherical hearths 2 in flue 3 week footpath, the dividing plate 2.1 by the spiral setting on burner hearth 2 perisporiums constitutes spirals and leads quirk, have in the combustion space 2.2 of burner hearth bottom bottom flue be cross structure put piece 5.Circular salt pond flue 8 by heat-resisting manganese steel is made is shelved in the burner hearth, and its top has one to turn up limit 3.1 to what turn up.The tangential oil fuel burner 4 that is provided with is positioned at (end) portion under the body of heater.The burner hearth of the furnace body top also is provided with smoke outlet (not providing among the figure).
Utility model is owing to adopt oil fuel burner to replace heated by electrodes salt bath medium-salt, and it is fast that existing electrode salt bath furnace has heat-up rate, and energy consumption is low energy-conservation, and the barrel-shaped flue replacement charge of metal is low, and the inner bag maintenance is convenient, and use cost is low; And can omit complicated electrical control cubicles and transformer, and low equipment investment, easy to operate; Because without electrode, thereby the harm that can avoid other part of thermal treatment to fall to causing.
Claims (6)
1, a kind of improved salt bath furnace, comprise body of heater and be arranged on and be jealous of intravital salt pond flue and heating fused salt device, it is characterized in that said body of heater has one than the big burner hearth in salt pond flue week footpath, the burner hearth perisporium is provided with spiral quirk and the smoke outlet of leading, said salt pond flue is the barrel-shaped flue of metal, and said heating fused salt device is the tangential oil fuel burner that is provided with.
2,, it is characterized in that there is outer flanging said flue top according to the described improved salt bath furnace of claim 1.
