Background technology
The feeding device of traditional high-presure polyurethane foaming machine, its structure comprises: installing rack, two batch cans are installed on installing rack, the top of each batch can is provided with charging aperture, on each charging aperture, be all connected with feed pipe, be provided with interior bonding gear pump on every feed pipe, two feed pipes are connected with two Raw material pails respectively, the bottom of each batch can is provided with discharging opening, on each discharging opening, is provided with discharge nozzle.The feeding device of the high-presure polyurethane foaming machine of said structure is for by two kinds of urethane raws in two Raw material pails---PPG and isocyanates are pumped respectively in two batch cans, and then is dosed to respectively in the mixing head of two kinds of raw materials in high-presure polyurethane foaming machine by the discharge nozzle of two batch cans.But there is following defect in the feeding device of said structure: one, pump respectively to PPG and isocyanates viscosity in two batch cans greatly, be difficult to export in mixing head separately from the discharge nozzle of batch can separately; Two, because PPG and isocyanates have corrosivity, the sealing in the interior bonding gear pump on feed pipe easily damages, and causes raw material to leak, and causes environmental pollution.
Summary of the invention
The object of the invention is: provide a kind of simple in structure, can make two urethane raws in batch can easily be dosed in the mixing head of two kinds of raw materials, and the feeding device of the high-presure polyurethane foaming machine of long service life.
For achieving the above object, the technical solution used in the present invention is: installing rack, two batch cans are installed on installing rack, the bottom of each batch can is provided with discharging opening, on each discharging opening, be all connected with discharge nozzle, the top of each batch can is provided with charging aperture, on each charging aperture, be provided with feed pipe, every feed pipe is connected with two Raw material pails respectively, on every feed pipe, be provided with pneumatic diaphragm pump, in each batch can, be all provided with heat(ing) coil, in each batch can, be also provided with shaft, the bottom of shaft is provided with agitator arm, all stretch out from the top of corresponding batch can the upper end of every shaft, and be connected with the shaft drive unit at this batch can top, under the driving of shaft drive unit, corresponding shaft can drive the agitator arm on it to rotate, shaft in each batch can and agitator arm are all positioned at the center of the heat(ing) coil of this batch can.
Further, the feeding device of aforesaid high-presure polyurethane foaming machine, wherein, is provided with on each batch can for monitoring the temperature sensor of batch can internal temperature.
Further, the feeding device of aforesaid high-presure polyurethane foaming machine, wherein, described shaft drive unit is stirring motor, the output shaft of stirring motor is fixedly connected with the upper end of shaft.
Advantage of the present invention is: simple and practical, and by heat(ing) coil and agitator arm, respectively the raw material in batch can is heated and stirred, greatly improve the mobility of batch can Raw, thereby greatly facilitated raw materials to mixing head; In addition, owing to adopting pneumatic diaphragm pump on feed pipe, effectively prevent from occurring because raw material corrosion causes the phenomenon that raw material leaks after pump housing bad seals, also greatly extended the service life of the pump housing simultaneously.
