Description
Technical field
The utility model relates to a kind of forging heating furnace, is specifically related to a kind of heat accumulating type forging heating furnace.
Background technology
Need carry out The pre-heat treatment to forge piece blank reheating with the forging heating furnace during forging; Present widely used coal gas, natural gas forge furnace major part are adopted horizontal cylindricality body of heater; One end of body of heater feeds fuel and combustion-supporting gas; The other end of body of heater is provided with the tail gas outlet, and the middle part of body of heater is provided with blank preheating mouth.Particularly be directed to the heating of leaf springs of car blank, normally have one along body of heater heating gate radially at the body of heater middle part, the leaf spring blank treats that the part insertion heating gate of forging heats.
Though traditional forging heating furnace can satisfy the needs of blank preheating to a certain extent; But still exist some following problems in the actual use: 1; Because waste gas after burning is directly discharged; This part waste gas has 500～700 degrees centigrade temperature usually, and directly discharging has not only been wasted the energy but also caused the serious environmental pollution.2, fuel and combustion air all are directly to blast heating furnace under the normal temperature, need to absorb certain heat, cause the temperature in the heating furnace not high enough, have only 1000 deg.c, and the heating furnace utilization ratio is low, and energy consumption is big; 3 because the motion from one end to the other side always of the burning in the body of heater; It is even inadequately to cause stove inside to be heated, and is unfavorable for the stable heating of blank.
The utility model content
It is little that the technical problem that the utility model will solve provides a kind of energy consumption, the recyclable waste-gas heat that utilizes, the little and interior uniform forging heating furnace of temperature of stove of environmental thermal pollution.
In order to address the above problem, the utility model provides a kind of heat accumulating type forging heating furnace, comprises the burner hearth, burner, Gas Pipe and the air hose that are provided with heating gate; Said burner has two; Be located at the burner hearth two ends respectively, said Gas Pipe is the Y shape structure that is provided with an import of two outlets, and two outlets are connected on said two burners; The Y shape intersection of Gas Pipe is provided with reversal valve; Described air hose is "+" shape four-hole structure, and two mouthfuls that one of which is relative connect air intlet and Waste gas outlet respectively, and another relative two mouthfuls are connected on the burner; The junction of burner and air hose is provided with heat storage, and intersection's diagonal of said air hose is provided with two stop valves of alternately opening.
Regulating reversal valve and stop valve makes an end of burner hearth advance combustion gas and air simultaneously; Combustion gas and air take fire after burner mixes; The burner of waste gas through the other end of burner hearth passes and heats heat storage and get into air hose, gets into Waste gas outlet after arriving the stop valve place; Regulate reversal valve and stop valve once more; This moment, the other end of burner hearth got into combustion gas and air simultaneously; Before air got into burner, the place was heated at heat storage, promptly takes fire after higher temperature and the combustion gas mixing; Tail gas from the burner of a relative end pass and heat heat storage after get into air hose, get into exhaust port at last.
Adopt the heat accumulating type forging heating furnace of technique scheme to have following advantage: 1, the heat of tail gas is used to reclaim and add hot-air, makes air when combustion-supporting, and the energy that itself consumes reduces, and the heating furnace energy consumption reduces, the recyclable utilization of waste-gas heat; 2, because the preheating before the exhaust emissions is recovered, the temperature of tail gas reduces, and the thermal pollution to environment during discharging is less; 3, owing to taked the mode of burner hearth two ends alternate combustion heat supplies, the temperature in the stove is even, has improved the heating quality of forging.
As preferred version, in order better to improve the heat-exchange capacity of heat storage, described heat storage is the ceramic honeycomb heat storage.
As preferred version, in order to improve the automaticity of air feed and exhaust, reduce the difficulty of controlling, described reversal valve and stop valve are magnetic valve.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model heat accumulating type forging heating furnace.
The specific embodiment
As shown in Figure 1, the utility model provides a kind of heat accumulating type forging heating furnace, comprises the burner hearth 1, the left and right burner 21 that are provided with heating gate; 22, Gas Pipe 3 and air hose 4, left and right burner 21,22 is located at the two ends of burner hearth 1 respectively; Wherein Gas Pipe 3 is for being provided with the Y shape structure of an import of two outlets, and two outlets are connected on the left and right burner 21,22; The Y shape intersection of Gas Pipe 3 is provided with solenoid directional control valve 5, and air hose 4 is "+" shape four-hole structure, and two mouthfuls that one of which is relative connect air intlet 7 and Waste gas outlet 8 respectively; Another relative two mouthfuls are connected on the left and right burner 21,22, left and right burner 21; 22 are provided with ceramic honeycomb heat storage 6 with the junction of air hose 4, and intersection's diagonal of air hose 4 is provided with two electromagnet cut off valve of alternately opening 9.
Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection domain of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
