Description
Technical Field
The invention relates to the technical field of internal mixer operation on-line monitoring, in particular to an internal mixer operation on-line monitoring method and system.
Background
The internal mixer is mainly used for plasticating and mixing rubber. An internal mixer is a machine which is provided with a pair of rotors which are of specific shape and relatively rotate, plasticates and mix polymer materials in a clearance way under a closed state with adjustable temperature and pressure, and mainly comprises a banburying chamber, the rotors, a rotor sealing device, a feeding and pressing device, a discharging device, a transmission device, a stand and the like.
When the internal mixer works, the two rotors rotate relatively, materials from the charging port are clamped and brought into the roll gap to be extruded and sheared by the rotors, and the materials are separated into two parts after passing through the roll gap and then touch the sharp edges of the lower top bolts, and the two parts respectively return to the upper part of the roll gap along the gap between the front chamber wall and the rear chamber wall and the rotors. In the circle of the flowing of the rotor, the materials are sheared and rubbed everywhere, so that the temperature of the rubber material is rapidly increased, the viscosity is reduced, the wettability of the rubber on the surface of the compounding agent is increased, and the rubber is fully contacted with the surface of the compounding agent. The complex agent agglomerate is sheared and crushed along with the sizing material through the gap between the rotor and the rotor, the gap between the rotor and the inner wall of the internal mixing chamber, and is surrounded by the rubber which is deformed by stretching and is stabilized in the crushing state. Simultaneously, the convex edges on the rotor enable the sizing material to move along the axial direction of the rotor, so as to play a role in stirring and mixing, and the matching agent is uniformly mixed in the sizing material. The compounding agent is repeatedly sheared and crushed in this way, the sizing material repeatedly generates deformation and recovery deformation, and the rotor convex edges are continuously stirred, so that the compounding agent is uniformly dispersed in the sizing material, and a certain dispersity is achieved. The shearing action of the rubber material is much larger than that of the open mill during mixing of the internal mixer, and the mixing temperature is high, so that the mixing efficiency of the internal mixer is much higher than that of the open mill.
The prior art has the following defects: in the running process of the internal mixer, the internal mixer is aged or damaged due to long-term use or external factors, when the heat insulation material on the surface of the internal mixer is partially aged or damaged, the internal mixer cannot be timely found out that the internal mixer is not insulated, when the internal mixer is in the condition, the internal mixer cannot be timely found out, and the internal mixer can timely find out that serious hysteresis exists along with the deterioration of the preparation effect of rubber (the influence on the preparation effect of the rubber when the temperature change range in the internal mixer is large) and the reduction of the preparation efficiency of the rubber, and during the period, the preparation of the rubber is seriously influenced; secondly, when the heat insulation material on the surface of the internal mixing chamber is aged or damaged, the aged or damaged positions cannot be accurately determined, the aged or damaged positions are required to be checked one by one, the aged or damaged positions are found out for maintenance, the maintenance efficiency is extremely low, and the efficient use of the internal mixer is not facilitated.
