Functional plastic banburying method and banbury mixer

Abstract

The invention relates to a functional plastic banburying method and a banbury mixer. The banbury mixer comprises a pot body with an open top, and is characterized in that the refining machine furthercomprises a stirring mechanism extending into the pot body and an insulating shell arranged outside the pot body in a sleeving mode, the stirring mechanism comprises an inner stirring paddle located at the bottom of the pot body and an outer stirring paddle covering the top of the pot body, the outer stirring paddle is connected to a gear ring in a transmission mode, the inner stirring paddle is connected to a sun wheel in a transmission mode, and the sun wheel and the gear ring are connected by a fixed planetary frame to form a planetary deceleration mechanism; and the inner wall of the insulating shell and the outer wall of the pot body enclose a closed oil bath space, phase change materials attached to the outer wall of the pot body are arranged in the oil bath space, the phase change materials abut against heat pipes, and the cold ends of the heat pipes are connected with an electric heater. The stirring efficiency can be improved through same direction and reverse stirring of theinner stirring paddle and the outer stirring paddle, the phase change materials in the latent heat state can heat the pot body at a high speed, and heating efficiency is improved by using the temperature difference; and through improvement of heating efficiency and stirring efficiency, energy consumption of the whole banburying process can be lowered.

Description

technical field [0001] The invention belongs to the field of chemical raw material smelting, and in particular relates to a functional plastic internal mixing method and an internal mixer specially used for the internal mixing method. Background technique [0002] Functional plastic masterbatch is processed by resin and various mixing additives through multiple processes such as banburying. The melting points of the resin and the additives are often quite different, and the additives with low melting points melt very early in liquid form. Exists in a cauldron. In the existing process, the melting of functional plastic masterbatch usually adopts the method of directly adding resin and additives to the internal mixer for internal mixing, such as the prior patent CN105345940B - top-suspended automatic flip plastic masterbatch barrel-type internal mixer . The disadvantages of this smelting process are: high energy consumption, continuous high-temperature heating will greatly i...

AI Technical Summary

Problems solved by technology

The disadvantages of this smelting process are: high energy consumption, continuous high-temperature heating will greatly increase the energy consumption required for the entire masterbatch smelting process, especially the continuous maintenance of the liquid state of the additive will sharply increase the required Energy consumption is contrary to my country's current industrial development concept of energy saving and emission reduction; melting efficiency is low. Although the heating temperature and stirring speed are adjustable on the melting machine, the adjustment range and sensitivity are extremely limited, and it is difficult to Adjust the temperature and stirring rate to the appropriate range in an extremely fast range, causing the problem of reduced melting efficiency
