Abstract
A melting kettle for processing of thermoplastic material. The kettle disclosed herein obtains heat transfer by use of an oil jacketed tank with an adjoining main tank for storage of hot oil and a hose tank for recovery of the hot oil. Oil expelled from the oil jacket is directed to the main tank through an opening. Spillage of oil from the hose tank is directed to the main tank through an aperture. The melting kettle reduces the space needed for oil storage, and increases operator safety by eliminating additional transfer lines. Dual kettles benefit by having the adjoining main tank placed therebetween.
Claims9
A dual melting kettle comprising:
- a first kettle having a cylindrical bottom with a first continuous sidewall extending upwardly therefrom to a top, said first sidewall encompassed by a first oil jacket formed adjacent thereto for dispersion of hot oil around said first kettle sidewall;
- a second kettle having a cylindrical bottom with a second continuous sidewall extending upwardly therefrom to a top, said second sidewall encompassed by a second oil jacket formed adjacent thereto for dispersion of hot oil around said second kettle sidewall;
- an outer wall formed around said first oil jacket of said first kettle and said second oil jacket of said second kettle forming a main tank and a hose tank;
- and a cover enclosing the tops of said first and second kettle, said main tank and said hose tank;
- wherein hot oil is introduced into each said first and second oil jacket for heating material placed in said kettles, said hot oil is expelled from said oil jackets into said main tank, whereby oil is drawn from said main tank for reheating through said hose tank.
