Inversion type casting ladle roaster
Technical field
The utility model relates to a kind of casting casting ladle roaster, is specifically related to the inversion type casting ladle baking device of a kind of oven dry for industry of casting, preheating and insulation.
Background technology
Cast casting ladle used, will carry out toasting to remove moisture content after newly building bag, reach just hard; Casting ladle in using, according to technological requirement, carry out the insulation before heat temperature raising or casting next time.Existing casting ladle baking device is all along vertical casting ladle center suitable for reading, and installs a burner jetted out flames or burning downwards and chew and heat, flame and air-flow rise backflow soon, and the thermal efficiency is low; Some large-scale casting ladle is for utilize heat energy better, one piece of cover plate is provided with at burner place, flue gas is forced to be discharged along casting ladle wall mouth, because flame thermal current is all under household condition vertical upflow, and when configuring roaster for preventing flame washing away casting ladle wall, allowing flame and casting ladle wall there is certain distance, and having flowed out on just turning to after commitment positions under flame, mainly radiant heat transfer around here, conduction and convection heat transfer efficiency is extremely low; In addition, the heat smoke turned to can carry out more baking to burner again, thus the problems such as the service life of the burner that has an impact.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field exists, the purpose of this utility model is, provide a kind of inversion type casting ladle roaster, easy to use, the thermal efficiency is high, long service life.
The inversion type casting ladle roaster that the utility model provides, be provided with frame, described frame has a table top, table top can be quadrangle, also can be circular or other shape, table top bottom is supported by leg, table top is lifted to suitable dimension, and the parts being convenient to upper and lower part are installed, and the parts installed comprise heat insulation facility, thermocouple, burner or burning and chew.Centre bore and screw that install combustion device or burning chew is had in the middle part of described table top, described heat insulation erection of equipment is on table top, the corresponding centre bore having install combustion device or burning and chew, and have the larger-diameter circular counter bore overlapping with the center of centre bore, described burner or burning are chewed inversion and are arranged on table top and central hole that heat insulation facility is opened, and burner upward.
Described burner or burning are chewed and are produced heat energy with liquid or gaseous fuel burning; Described heat insulation facility is refractory brick, and on refractory brick, institute's opened round counterbore inside edge is provided with thermocouple mounting hole, and the installation of TC is in thermocouple mounting hole, and sinking certain distance, avoids directly irradiating by flame, is conducive to measuring the actual temperature in heating casting ladle; The outer rim of refractory brick circular counter bore has some passages, as exhaust gases passes.
Inversion type casting ladle roaster, the casting ladle that need toast processing is inverted in refractory brick center, and burner or burning are chewed and controlled by control system, and control system is connected with thermocouple.
The inversion type casting ladle roaster that the utility model provides, its beneficial effect is, automaticity is high, facilitates laying and toasting of casting ladle.During baking, after setting running parameter, casting ladle of putting upside down, open gauge tap, it just can toast casting ladle automatically under control of the control system, until reach design temperature or automatically stop after the time, can automatically toast again after dropping to uniform temperature next time; Be inverted the combustion flame of burner upward, thermal current subsequently also upwards flows and can touch in ladle liner, and flows to casting ladle mouth in ladle liner, then flows out through the exhaust gases passes of refractory brick, and produce more heat exchange with casting ladle, heat utilization efficiency is high; Deep burner or burning are chewed again simultaneously: be conducive to the heating to casting ladle on the one hand, decrease the barbecue chewed burner or burning, the service life that prolonging combustion device or burning are chewed on the other hand; The installation of TC comparatively depths in thermocouple mounting hole, effectively avoid flame directly to roast and flame direct irradiation, serious field survey casting ladle toasts the temperature reached, thus reaches the stable object automatically controlled.

Detailed description of the invention
With reference to the accompanying drawings, in conjunction with an embodiment, the inversion type casting ladle roaster that the utility model provides is described in detail.
Embodiment
With reference to Fig. 1-Fig. 2, the inversion type casting ladle roaster of the present embodiment, is provided with frame, described frame is provided with a quadrangle table top 8, table top 8 bottom is supported by leg 6, and the parts being convenient to upper and lower part are installed, and the parts installed comprise burner 5, refractory brick 3 and thermocouple 4.Centre bore and the screw of install combustion device 5 is had in the middle part of described table top 8, described refractory brick 3 is arranged on table top 8, the corresponding centre bore having install combustion device 5, and have the larger-diameter circular counter bore 9 overlapping with the center of centre bore, described burner 5 be inverted be arranged on table top 8 and refractory brick 3 open central hole, burner is upward.
On refractory brick, institute's opened round counterbore inside edge is provided with thermocouple mounting hole, and thermocouple 4 to be arranged in thermocouple mounting hole comparatively depths, avoids, directly by according to flame 2, measuring the temperature of heating environment; The outer rim of refractory brick 3 circular counter bore has some passages 7, as exhaust gases passes.
Inversion type casting ladle roaster, burner is controlled by burner control system, control system is connected with thermocouple, the casting ladle 1 that need toast processing is inverted in refractory brick center, after setting running parameter, and casting ladle of putting upside down, open gauge tap, it just can toast casting ladle automatically under control of the control system, until reach design temperature or automatically stop after the time, can automatically toast again after dropping to uniform temperature next time.
