The upper end of the supporting frame is connected with an insulated heat preserving shell with a tunnel furnace chamber. The insulated heat preserving shell is additionally connected with a supporting air cylinder. A pair of top covers is arranged at the top end of the insulated heat preserving shell. A bottom heating air inlet pipe is arranged in the tunnel furnace chamber. A bottom heating device heating pipe is arranged above the bottom heating air inlet pipe. A conveying device is arranged above the bottom heating device heating pipe. A conveying chain assembly is arranged on the conveying device. A hot air spray nozzle which is communicated to a bellows is arranged at a corresponding position above the conveying chain assembly. A top heating device air inlet pipe with a heater is connected onto the bellows through an air blowing fan. An air return pipe is arranged on the top heating device air inlet pipe. A fan motor which is used for controlling the air blowing fan is arranged at the external part of the insulated heat preserving shell. A wiring channel is arranged on the fan motor. A handle is arranged on the side end of the insulated heat preserving shell. The heating unit is used for basic splicing, the omnibearing top and bottom heating of workpieces is realized through each hot air circulation heating unit in the tunnel furnace, and the temperature of the tunnel furnace is well guaranteed.
Description
Technical field
The utility model belongs to heating continuous tunnel furnace structure field, particularly a kind of heating unit of wide furnace chamber continuous tunnel furnace.
Background technology
continuous tunnel furnace is a kind of commonly used be used for heating pre-heated work pieces semi-finished product or finished product automatic production line equipment, along with science and technology and industrial expansion, the continuous tunnel furnace of various model sizes emerges in an endless stream, it is more rare that but the large tunnel stove is used for the continuous tunnel furnace of large-scale semi-finished product finished product heating, mainly because the heating uniformity problem of large tunnel stove is difficult to be resolved, the furnace chamber of continuous tunnel furnace is larger, the uniformity of heating is more bad, heating effect is poorer, therefore the problem that how to solve wide furnace chamber continuous tunnel furnace heating uniformity becomes the problem that at first large-scale heating continuous tunnel furnace will solve of making.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of heating unit of wide furnace chamber continuous tunnel furnace, has characteristics easy to use simple in structure.
To achieve these goals, the technical solution adopted in the utility model is:
a kind of heating unit of wide furnace chamber continuous tunnel furnace, comprise bracing frame 6, leg 18 at the bottom of bracing frame 6 lower ends connection leveling, the thermal insulating shell 14 of bracing frame 6 connecting band tunnel, upper end furnace chambers 19, thermal insulating shell 14 also connects support cylinder 7, there is a pair of top cover 12 on the top of thermal insulating shell 14, lower heating intake stack 17 is arranged in tunnel furnace chamber 19, lower heating intake stack 17 top cloth deposit heater heating tube 8, there is conveyer 16 lower heater heating tube 8 tops, transmission chain assembly 2 is arranged on conveyer 16, the hot-blast spray nozzle 9 that is communicated to bellows 10 is arranged in the top of transmission chain assembly 2 correspondences, be connected with upper heater intake stack 11 with heater 20 by air blast blower fan 13 on bellows 10, on upper heater intake stack 11, return air duct 15 is set, control the blower motor 3 of air blast blower fan 13 in thermal insulating shell 14 outer setting, trough 4 is arranged on blower motor 3, thermal insulating shell 14 sides arrange handle 5.
Compared with prior art, the utility model can be used in basis splicing, by each Cycling hot-blast heating unit in continuous tunnel furnace, workpiece is carried out omnibearing heating up and down, and the continuous tunnel furnace shell adopts the insulation heating material to surround, and has guaranteed well the temperature of continuous tunnel furnace.
