Dewaxing furnace is to be 8KG/CM at steam pressure2Condition under use, current equipment is after dewaxing completes, wax liquid is got rid of by wax conveying tube, generally to use power set to carry out discharge opeing, and the distance of wax conveying tube is 3-10M, in distance so far away, because pipeline is steel pipe, during the course can be cooling, and the fusing point of wax is 60 DEG C, at this moment the wax liquid in steel pipe just solidifies, traditional way is at wax conveyance conduit outside bag heat tape or Electrothermal ring, or with conduction oil, oil pump and protective sleeve carry out the insulation of wax conveying tube road, once these way temperature controls, will cause wax burning, there is potential safety hazard, heat wax conveying tube road simultaneously, also expend more energy.
Utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of energy-conservation automatic de-waxing dewaxing system, comprise dewaxing furnace, wax liquid recycling bin, described dewaxing furnace comprises body of heater, described body of heater is provided with air inlet, gas outlet, wax outlet, on described wax outlet, be connected with wax conveying tube, described wax conveying tube leads to described wax liquid recycling bin, and described wax conveying tube outer cover has heat-insulating cover; On described gas outlet, be communicated with escape pipe, described escape pipe is communicated with described heat-insulating cover; In described body of heater, be provided with bracket, described bracket is provided with foundry goods shell mould; Described bracket bottom is wax liquid cavity volume.
Preferably, between described heat-insulating cover and described wax conveying tube, be provided with the gap of 3-5mm.
Preferably, described gas outlet is positioned at described upper of furnace body.
Preferably, described heat-insulating cover end is provided with blast pipe.
Preferably, described escape pipe is provided with air bleeding valve.
The energy-conservation automatic de-waxing dewaxing system the utility model proposes has following beneficial effect: by controlling the steam intake in dewaxing furnace, change the pressure in dewaxing furnace, control wax liquid and pass into wax liquid recycling bin, extension steam is between wax conveying tube and thermal insulation casing simultaneously, utilize vapor (steam) temperature that the temperature of wax conveying tube is controlled to 100-150 DEG C, ensure that wax liquid can not solidify, do not need extra ceratuba road heat-preserving equipment yet, equipment cost and energy consumption are reduced, because adopt the steam of getting rid of to be incubated, avoided the burning of wax liquid simultaneously.
