Technical field
The present invention relates to the hot-air blowing device, particularly a kind of hot-air blowing device that is applied to paraffin continuous shaping machine casting device.
Background technology
Existing paraffin continuous shaping machine casting device all is not provided with the hot-air blowing device to liquid ceratuba road, liquid wax pump and valve; Therefore when the casting device quits work; The liquid wax that is trapped in liquid ceratuba road, liquid wax pump and the valve solidifies immediately, can only before start once more, heat it with hot water or steam to make its fusing, and this preparation often reaches 1h～2h; Waste the effective time, reduced utilization rate of equipment and installations.
Summary of the invention
The present invention discloses a kind of hot-air blowing device, efficiently solves the problem that prior art exists.This hot-air blowing device is made up of miniature braze welding type plate type heat exchanger (1), magnetic valve (3), steam control valve (16), hot air duct (12) and automatic control system; Heat exchanger (1) is installed in the column inboard of paraffin continuous shaping machine head framework front center; Four interfaces are connected respectively as follows: compressed air inlet (2) are connected with the compressed air piping silk; Steam inlet (15) is connected with jet chimney; Hot-blast outlet (13) is connected with liquid wax runner (9) silk, and steam (vapor) outlet (14) is connected with vapor return line; Automatic control system is mainly implemented control automatically through main frame PLC system to steam control valve (16), magnetic valve (3), casting valve outlet port (8) and stop valve (4).
Magnetic valve (3) is installed in front, said compressed air inlet (2), timing automaticly opens or closes.
Steam control valve (16) is installed in front, said steam inlet (15), timing automaticly opens or closes.
Said hot-blast outlet (13) is connected with liquid wax runner (9) silk of liquid wax pump intake (11) by hot air duct (12).
Stop valve (4) is installed in liquid wax runner (9) upper end of said liquid wax pump intake (11).
Said heat exchanger (1) is a rectangle, overall dimensions 150mm * 80mm * 30mm.
Advantage of the present invention: the timely purging of stagnant liquid wax when realization is shut down liquid wax runner, prevent to solidify, saved the time that need change wax when starting shooting again, improved utilization rate of equipment and installations.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further explain.
Fig. 1 is a hot-air blowing device schematic flow sheet.
Icon: heat exchanger 1, compressed air inlet 2, magnetic valve 3, stop valve 4, liquid wax pump 5, flowmeter 6, casting valve 7, casting valve outlet port 8, liquid wax runner 9, liquid wax pump discharge 10, liquid wax pump intake 11, hot air duct 12, hot-blast outlet 13, steam (vapor) outlet 14, steam inlet 15, steam control valve 16.
The specific embodiment
As shown in Figure 1, the hot-air blowing device is made up of miniature braze welding type plate type heat exchanger 1, magnetic valve 3, steam control valve 16, hot air duct 12 and automatic control system.Heat exchanger 1 characteristics are that little (overall dimensions 150mm * 80mm * 30mm), heat exchange efficiency are high for volume; The column that is installed in paraffin continuous shaping machine head framework front center is inboard; Four interfaces are connected respectively as follows: compressed air inlet 2 is connected with the compressed air piping silk; Magnetic valve 3 is installed in 2 fronts, compressed air inlet, can timing automaticly as required open or close, and its aperture size is also carried out according to the parameter of design setting; Steam inlet 15 is connected with jet chimney, and steam control valve 16 is installed in 15 fronts, steam inlet, opens or closes according to the steam flow of setting is timing automatic, and its aperture size is also carried out according to setup parameter; Hot-blast outlet 13 is connected with 9 of the liquid wax runners of liquid wax pump intake 11 by hot air duct 12; Steam (vapor) outlet 14 is connected with vapor return line; A stop valve 4 is installed in liquid wax runner 9 upper ends of liquid wax pump intake 11.
Automatic control system is mainly implemented control automatically through main frame PLC system to steam control valve 16, magnetic valve 3, casting valve outlet port 8 and stop valve 4; Liquid wax still keeps liquid when being main shut-down system; Open with being about to steam control valve 16, magnetic valve 3 and casting valve outlet port 8, close automatically by setting-up time; Guarantee that with hot-air pre-heating liquid ceratuba road the start casting is smooth and easy earlier before the start.
During work, compressed air gets into heat exchangers 1 distinguished and admirable road by the compressed air inlet of heat exchanger 12, with the steam that gets into heat exchangers 1 steam flow channel by steam inlet 15 in heat exchanger 1 after the moment heat exchange, steam flows to vapor return line by steam (vapor) outlet 13; Hot blast gets into liquid wax runner 9 through hot-blast outlet 14, passes through liquid wax pump 5, flowmeter 6, casting valve 7 to casting valve outlet port 8 successively, the liquid wax that is trapped in liquid wax runner 9 is purged in the empty cake wax of casting valve outlet port 8 correspondences; With hot blast liquid wax runner 9 is purged preheating successively again before start next time, guarantee that casting is smooth and easy.When purging, be closed in the stop valve 4 of liquid wax runner 9 upper ends simultaneously, after the preheating before the start next time stop valve 4 is opened.Each purging and preheating time, hot blast temperature will be higher than current casting temperature 2 degree～3 degree respectively at 3min～5min, and wind speed (pressure) is moderate, with the anti-tamper flowmeter.
