Problems solved by technology

However, the screw continuous kneading process has limited output torque for emerging composite resin materials, and is not suitable for composite materials with too high solid content, and the equipment is suitable for single materials. The gap between them is relatively large, and when kneading the composite resin materials with high viscosity and high molecular weight polymers containing small component fillers developed in recent years, there are problems such as inability to provide large shear force and insufficient kneading; many The chamber continuous kneading process has large output torque and high kneading capacity, but due to the small number of variable parameters of the equipment, it cannot respond to the needs of different kneading temperatures, shear stresses, and residence times for different high-viscosity composite materials.

Abstract

The invention discloses a modularized multi-chamber continuous kneading machine which can be applicable to high-solid-content composite materials. The equipment is flexible, and kneading is full. Thedevice comprises a hopper 8, chambers 6, paddles 7, a sieve plate 9, connecting screws 5, a support 4, a guide rail 2, fastening screws 3 and a base 1. Each paddle is driven independently, larger torque is provided, the number of the chambers arranged in a series-connection manner is changed to adapt to materials with different solid contents, the stay time of the materials is adjusted, by means of counter rotating of the paddles, the materials are pushed in the tangential direction while being kneaded, and continuous flowing of the materials among the chambers is achieved. According to the machine, the defects of an existing screw continuous kneading technology, a double-rotor continuous mixing technology, a multi-chamber continuous kneading technology and the like are made up, the kneading ability of the kneading equipment is improved, flexibility is higher, autonomy is higher, and the application range of the equipment is expanded.

Description

technical field [0001] The invention belongs to the field of continuous kneading and relates to a multi-chamber continuous kneader, in particular to a modular multi-chamber kneader for continuous kneading of materials with high solid content. Background technique [0002] In recent years, due to the continuous development of new composite resin materials, especially the increase in the types of high-viscosity composite materials, and the increasing proportion of solid phase content in composite materials, the demand for continuous kneading equipment to improve kneading ability and wider application range is increasing. rise. [0003] Currently commonly used continuous kneading processes include screw continuous kneading process, twin-rotor continuous mixing process, multi-chamber continuous kneading process, etc. However, the screw continuous kneading process has limited output torque for emerging composite resin materials, and is not suitable for composite materials with t...
