Problems solved by technology

[0002] The extruder has various functions, so it is widely used in the fields of feed, food, plastic and battery slurry. Existing extruders mostly use twin-screw extruders, and there is only one meshing zone in the mixing area. In order to strengthen the twin-screw extruder The mixing ability is usually solved by lengthening the length-to-diameter ratio of the screw, so the length-to-diameter ratio of the battery slurry twin-screw extruder reaches 44:1 or above. The extruder with a large length-to-diameter ratio takes up a lot of space and requires a large drying plant area. High consumption, low output, and limited by the exhaust capacity, the air inside the extruder is not easy to discharge, so a vacuum device must be installed in the next process

Abstract

The invention provides a linear equidirectional parallel three-screw extruder which comprises a rack, a motor, a gear box and a screw sleeve arranged on the rack, wherein a screw assembly is arrangedin the screw sleeve and comprises three linear parallel screws, the adjacent screws are meshed with one another, the motor drives the three screws to rotate in the same direction through the gear box,each screw comprises a mandrel, a threaded conveying element and a threaded mixing element are arranged on each mandrel, the threaded conveying elements are arranged in a partitioned mode through thethreaded mixing elements. a cutting device is connected to the output ends of the screws, the thread sleeve is further in communication with a vacuumizing device and a conditioner, the conditioner isconnected with a feeder, and the feeder feeds materials into the thread sleeve through the conditioner. According to the three-screw extruder, the mixing performance and productivity of the existingextruder are improved, and the overall energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of extruders, and in particular relates to an inline co-rotating parallel three-screw extruder. Background technique [0002] The extruder has various functions, so it is widely used in the fields of feed, food, plastic and battery slurry. Existing extruders mostly use twin-screw extruders, and there is only one meshing zone in the mixing area. In order to strengthen the twin-screw extruder The mixing ability is usually solved by lengthening the length-to-diameter ratio of the screw, so the length-to-diameter ratio of the battery slurry twin-screw extruder reaches 44:1 or above. The extruder with a large length-to-diameter ratio takes up a lot of space and requires a large drying plant area. The consumption is high, the output is low, and the air in the extruder is not easy to be discharged due to the limitation of the exhaust capacity. The next process must be equipped with a vacuum device. Contents of th...
