Abstract
The utility model discloses an aluminum profile ageing furnace, including ageing furnace and gas direct heating device. The gas direct heating device includes combustion control valves group, combustion-supporting air blower, pipeline and gas burner. The utility model is characterized in that the gas burner connects the ageing furnace hearth through combustion chamber and radiator sleeve which connect in turn. The utility model has simple structure. The gas combusts completely in the combustion chamber and radiator sleeve. The high temperature combustion product mixes with the circulation air of low temperature (about 200 DEG C) in the furnace to ensure safety and reliability in order to achieve the goal of safe production.
Description
Technical field
The utility model relates to the low-temperature heat treatment stove, particularly a kind of combustion gas direct heating device of aluminium section bar aging oven.
Background technology
Along with aluminium section bar is applied in fields such as communications and transportation, the aluminium section bar size is increasing, presses for super-huge aluminium section bar timeliness equipment.But, reaching under the situation of identical furnace temperature, the size of aging oven is big more, and the heat that needs heating unit to provide is just many more, adopts the direct-fired mode of combustion gas, and is dangerous higher.So the low-temperature heat treatment stove just as the aluminium section bar aging oven, the direct-fired combustion safety of combustion gas is popular the attention always.
Summary of the invention
The utility model purpose is to provide a kind of aluminium section bar aging oven, and its combustion gas direct heating apparatus structure is simple, guarantees combustion completion, reliable simultaneously.
The purpose of this utility model is achieved in that a kind of aluminium section bar aging oven, include aging oven body of heater and combustion gas direct heating device, this combustion gas direct heating device comprises burning control valve group, combustion air gas blower and pipeline, fuel burner nozzle, and it is characterized in that: described fuel burner nozzle is connected with the aging oven burner hearth by combustion chamber, the heat-dissipating cylinder that is linked in sequence.
Described combustion chamber is fixed on the aging oven sidewall of the furnace body.
Described heat-dissipating cylinder is connected with the concentric assembly welding in combustion chamber, and extends in the aging oven burner hearth.
Described aging oven body of heater top is provided with the gas exhaust duct of band self-forced type flap valve.
Described fuel burner nozzle is divided into two groups or more, and is connected with the PID controller of its quantity combusted of may command.
The utility model is simple in structure, after the perfect combustion of combustion gas heat-dissipating cylinder in combustion chamber and stove, be incorporated into again in the stove internal recycle air-flow of low temperature (about 200 ℃), guarantee safe and reliable, in addition, gas exhaust duct is provided with the self-forced type flap valve, makes can guarantee that furnace pressure is certain in the unnecessary products of combustion in discharging stove, burner grouping PID control has solved oversize ageing furnace for aluminium profile economically owing to heat, be incubated the temperature-controlled precision problem that institute's heat requirement differs greatly and causes.

Embodiment
As shown in Figure 1, the utility model is a kind of oversize ageing furnace for aluminium profile, includes body of heater 1, two ends fire door and hoisting appliance 2 thereof, furnace gas pump circulation reversing mechanism 3, combustion gas direct heating device 4 trucks and towing mechanism 5 and electric control system.
As shown in Figure 2, combustion gas direct heating device 4 includes burning control valve group 401, combustion air gas blower and pipeline 402, fuel burner nozzle 403, combustion chamber 404, heat-dissipating cylinder 405 and gas exhaust duct 406.
As Fig. 3, burning control valve group 401, combustion air gas blower and pipeline 402 are connected with fuel burner nozzle 403 corresponding inlets respectively, and combustion gas and combustion air are provided to fuel burner nozzle 403.Fuel burner nozzle 403 is installed in body of heater 1 intermediate guide plate 303 tops, and its head be linked in sequence combuster 404 and heat-dissipating cylinder 405 are communicated with the burner hearth of aging oven.Combustion chamber 404 is run through aging oven body of heater 1 and is fixed on its sidewall, and heat-dissipating cylinder 405 is connected with combustion chamber 404 concentric assembly weldings and extends (as shown in Figure 4) in the aging oven burner hearth.The quantity combusted of the size of heat-dissipating cylinder 405 and fuel burner nozzle 403 adapts, thus guarantee combustion gas in heat-dissipating cylinder 405 fully, burning safely, high-temperature combustion product is vertical with stove internal recycle air-flow cross and rapid fusion even.Fuel burner nozzle 403 can be divided into two groups or more, and is connected with the PID controller of its quantity combusted of may command.In the present embodiment, be provided with four fuel burner nozzles 403 altogether, be divided into two groups, wherein three is one group, another is one group (as shown in Figure 2), and one group of 3 burner is turned off in two groups of totally 4 fuel burner nozzle 403 big load burnings during heating during insulation, control burning by 1 burner PID, thereby solve because the temperature-controlled precision problem that oversize ageing furnace for aluminium profile heats, required heat supplied differs greatly and causes when being incubated.
Aging oven body of heater 1 top is provided with gas exhaust duct 406, be provided with self-forced type flap valve 407 (as shown in Figure 5) in the gas exhaust duct 406, pressure hour, self-forced type flap valve 407 is closing condition, when pressure met or exceeded rated value, furnace pressure upwards backed down exhaust with self-forced type flap valve 407.Self-forced type flap valve 407 can with quantity combusted size, products of combustion what and open the opening that varies in size automatically and carry out exhaust, thereby guarantee that furnace pressure is certain.
