Abstract
A wide-furnace cavity tunnel furnace heating unit capable of ensuring the temperature of a tunnel furnace comprises a support frame; the upper end of the support frame is connected with an insulation heat preservation shell with a tunnel furnace cavity; the insulation heat preservation shell is connected with a support cylinder and is provided with a pair of top covers at the top end; a lower heating air inlet pipeline is arranged in the tunnel furnace cavity; a lower heating device heating pipe is arranged below the lower heating air inlet pipeline; a conveying device is arranged above the above the lower heating device heating pipe and is provided with a conveying chain assembly; the upside corresponding to the conveying chain assembly is provided with hot air nozzles communicated with a bellows; the bellows is connected with upper heating device air inlet pipelines with heaters by a blower; each upper heating device air inlet pipeline is provided with an air returning pipeline; a fan motor for controlling the blower is arranged at the outer part of the insulation heat preservation shell and is provided with a trunking slot; handles are arranged outside the insulation heat preservation shell. The wide-furnace cavity tunnel furnace heating unit capable of ensuring the temperature of a tunnel furnace is used for basis splicing, as each hot air circulating heating unit in the tunnel furnace heats a workpiece up and down in an omnibearing mode, so the temperature of the tunnel furnace is well ensured.
Description
Technical field
The invention belongs to heating continuous tunnel furnace structure field, particularly a kind of wide furnace chamber continuous tunnel furnace heating unit that guarantees tunnel furnace temperature.
Background technology
Continuous tunnel furnace is a kind of conventional 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, but large tunnel stove is more rare 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 first large-scale heating continuous tunnel furnace will solve of manufacturing.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of wide furnace chamber continuous tunnel furnace heating unit that guarantees tunnel furnace temperature, there is feature easy to use simple in structure.
To achieve these goals, the technical solution used in the present invention is:
A kind of wide furnace chamber continuous tunnel furnace heating unit that guarantees tunnel furnace temperature, 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, in tunnel furnace chamber 19, there is lower heating intake stack 17, lower heating intake stack 17 top cloth deposit heater heating tube 8, there is conveyer 16 lower heater heating tube 8 tops, on conveyer 16, there is transmission chain assembly 2, the hot-blast spray nozzle 9 that is communicated to bellows 10 is arranged in the top of transmission chain assembly 2 correspondences, on bellows 10, be connected with the upper heater intake stack 11 with heater 20 by air blast blower fan 13, on upper heater intake stack 11, return air duct 15 is set, at the blower motor 3 of thermal insulating shell 14 outer setting control air blast blower fans 13, on blower motor 3, there is trough 4, thermal insulating shell 14 sides arrange handle 5.
Compared with prior art, the present invention can be used in basis splicing, by each Cycling hot-blast heating unit in continuous tunnel furnace, workpiece is carried out to omnibearing heating up and down, and continuous tunnel furnace shell adopts insulation heating material to surround, and has guaranteed well the temperature of continuous tunnel furnace.
