Double-layer preheating kneader

Abstract

The invention relates to a double-layer preheating kneader. An upper-layer boiler body (5) is mounted on a slideway arranged on the upper surface of a lower-layer boiler body (8) through a slide block fixed on the underside of the upper-layer boiler body; a maintenance moving mechanism (2) is arranged between the upper-layer boiler body and the lower-layer boiler body; the maintenance moving mechanism (2) comprises a fixed support (21) of which the lower end is fixed on the lower-layer boiler body (8) and a movable support (17) of which the lower end is fixed on the upper-layer boiler body (5); the upper end of the fixed support (21) is provided with a drive mechanism for driving the upper-layer boiler body (5) to move on the lower-layer boiler body (8) along the horizontal direction; andthe outer end part of a drive rod of the drive mechanism is connected with the movable support (17). The maintenance moving mechanism is arranged between the upper-layer boiler body and the lower-layer boiler body; and when a stirring knife of the lower-layer boiler body is needed to maintain, the upper-layer boiler body can be directly removed from the lower-layer boiler body through the double-layer preheating kneader.

Description

technical field [0001] The invention relates to a kneading machine, in particular to a double-layer preheating kneading machine. Background technique [0002] The kneader is a kind of special kneading equipment for carbon or electrode production, but the existing kneader has the stirring knife in the lower pot, which is inconvenient to maintain, the transmission structure is not ideal, and the structure design of the discharge door is unreasonable; the stirring knife heating system is prone to failure oil seepage etc. [0003] The Chinese patent No. 200420018997.5 discloses a double-heating double-stirring preheating kneading pot. Its structural feature is that a double-layer structure is adopted, that is, an upper mixing tank is arranged on the upper part of the lower mixing tank; the stirring paddle shaft of the upper mixing tank passes through the chain It is connected with the stirring paddle shaft of the lower mixing tank; the discharge door is an inverted V-shaped hyd...

AI Technical Summary

Problems solved by technology

The disadvantage of this double-layer structure is: firstly, when the mixing blade of the lower mixing tank is maintained, the upper mixing tank needs to be removed from the lower mixing tank, and then the mixing blade in the lower mixing tank can be repaired, because The equipment is relatively large, and this maintenance method is time-consuming and laborious, and the operation is difficult

Secondly, the agitating paddle shafts of the upper and lower mixing tanks are connected by sprocket and chain transmission, and the upper and lower agitating paddle shafts can only move synchronously, and cannot achieve separate mixing of the upper or lower mixing knives. The operation is not flexible, which brings certain limitations to production.

Third, the blanking door adopts an inverted V-shaped hydraulic sliding door. The structure of this sliding door has poor sealing performance and material leakage will occur.

The existing mixing blades are severely worn by materials, especially the stirring blades of the upper pot body, which are worn at high speed at high temperature and have a short service life
