Efficient energy-saving single-screw extruder

Abstract

The invention discloses an efficient energy-saving single-screw extruder. The efficient energy-saving single-screw extruder is characterized by comprising a conventional device, a hopper, a machine barrel, a screw rod arranged in the machine barrel, a heating and cooling device, a lathe bed and an electrical control device, wherein the conventional device comprises a main motor and a reduction gearbox, the screw rod adopts equal-width separation-type threads, and the end, back on to the conventional device, of the screw rod is provided with a barrier head. The efficient energy-saving single-screw extruder has beneficial effects that as the screw rod adopts a mode of combining the equal-width separation-type threads and the barrier head, and the design of shallow slot threads is also added, added materials are rapidly and effectively conveyed, the retention time is shortened, efficient low-temperature plasticizing of the materials is accelerated, and the increase of production capacity is guaranteed; as the electrical control device has the function of interlocking control on all main systems of the whole set of the extruder, overloading running of equipment is effectively avoided, and the safety and the stability of the whole production process are ensured.

Description

technical field [0001] The invention relates to a high-efficiency and energy-saving single-screw extruder, which belongs to the technical field of material processing. Background technique [0002] In the plastic processing industry, the single-screw extruder is a common extrusion equipment. Because of its matters, the extrusion processing of most polymer materials, whether it is in the plasticizing granulation or molding process, the single-screw extruder is It occupies an important position. [0003] At present, the common single-screw extruder has low production efficiency, low output and high energy consumption. This shortcoming is mainly caused by the following two reasons: 1. The screw structure is mostly a screw structure with large diameter, deep groove, and high compression ratio. The material stays in the screw and barrel for a long time, which requires a high-power heating device and consumes a lot of energy. 2. The screw speed is low. The maximum speed of the t...

Problems solved by technology

[0003] At present, the common single-screw extruder has low production efficiency, low output and high energy consumption. This shortcoming is mainly caused by the following two reasons: 1. The screw structure is mostly a screw structure with large diameter, deep groove, and high compression ratio. The material stays in the screw and barrel for a long time, which requires a high-power heating device and consumes a lot of energy

2. The screw speed is low. The maximum speed of the traditional single screw is only 60~90rpm. The low speed limits the increase of the output of the extruder. If you want to increase the output, you can only increase the length-to-diameter ratio of the screw, thereby increasing the investment in equipment.
