Abstract
A feeding screw machine serves for feeding a processing screw machine. The feeding screw machine comprises a housing with at least one housing bore formed therein. An associated screw conveyor shaft is rotatably disposed in the at least one housing bore to convey material in a conveying direction from a supply opening to a feeding opening. An emptying opening is formed in the housing. The emptying opening enables an easy, fast and reliable emptying and cleaning of the feeding screw machine independently of the processing screw machine.
Claims17
A feeding screw machine for feeding a processing screw machine comprising:
- a housing,
- at least one housing bore formed in the housing,
- a supply opening formed in the housing for supplying material into the at least one housing bore,
- a feeding opening formed in the housing for feeding the material to the processing screw machine, and
- at least one screw conveyor shaft rotatably arranged in the at least one housing bore, for conveying the material in a conveying direction from the supply opening to the feeding opening,
- wherein an emptying opening is formed in the housing,
- wherein the emptying opening is arranged upstream of the supply opening in the conveying direction,
- wherein the at least one screw conveyor shaft extends in the at least one housing bore from the emptying opening to the feeding opening, and
- wherein the at least one screw conveyor shaft extends through the feeding opening and beyond the feeding opening.
A processing installation comprising:
- a processing screw machine for processing material, and
- a feeding screw machine for feeding the processing screw machine,
- wherein the feeding screw machine is a twin shaft side-feeding screw machine, the feeding screw machine comprising:
- a housing,
- two housing bores formed in the housing,
- a supply opening formed in the housing for supplying material into the two housing bores,
- a feeding opening formed in the housing for feeding the material to the processing screw machine, and
- two screw conveyor shafts rotatably arranged in the two housing bores, for conveying the material in a conveying direction from the supply opening to the feeding opening,
- wherein an emptying opening is formed in the housing,
- wherein the emptying opening is arranged upstream of the supply opening in the conveying direction,
- wherein the two screw conveyor shafts extend in the two housing bores from the emptying opening to the feeding opening, and
- wherein the two screw conveyor shafts extend through the feeding opening and beyond the feeding opening,
- wherein the two screw conveyor shafts extend into a material supply opening, the material supply opening being formed laterally in a housing of the processing screw machine.
