Description

Technical Field

[0001] The present invention relates to the technical field of graphite production, and particularly relates to a heating kneader for manufacturing isostatic graphite. Background Art

[0002] In current industrial production, graphite has become an essential key material. Especially in the solar energy industry, LED industry, semiconductor industry, and nuclear industry, the demand for graphite is increasing rapidly, and the quality requirements are also getting higher and higher. The raw materials for producing isostatic graphite include aggregate and binder. The specific production process of isostatic graphite is as follows: raw material grinding, heating kneading, secondary grinding, isostatic pressing, roasting, impregnation, graphitization, purification, etc.

The kneading box is supported by a support frame. The bottom end of the kneading box is communicated with the conveying pipe. One end of the conveying pipe is provided with a first motor, and a spiral conveying paddle connected to the output shaft of the first motor is arranged inside the conveying pipe.

[0020] The beneficial effects of the present invention:

[0021] 1. When the present invention is in use, since a grinding tooth disc and a limiting collar are fixedly connected to the first grinding disc, and a grinding ring tooth is fixedly connected to the second grinding disc, and the grinding ring tooth is arranged between the grinding tooth disc and the limiting collar. During the preliminary rough grinding process, the second grinding disc is driven to rotate by the first driving motor.

A stable support ring is fixedly connected to the upper end of the fixed base, and a stable support ring is fixedly connected to the lower end face of the second grinding disc. The stable support ring is movably sleeved on the stable support ring.

[0022] 2. After the kneading raw materials are preliminarily ground, since the kneading raw materials are in powder form at this time, the driving cylinder is used to drive the first grinding disc to rise, and then the driving motor 1 drives the second grinding disc to rotate rapidly, so that the powdered raw materials on the second grinding disc can be thrown out towards both sides of the second grinding disc. Due to the obstruction in the grinding chamber, the powdered raw materials enter the kneading chamber through the feeding hopper and the discharge port and are kneaded by the kneading stirring paddle. When raw materials need to be supplemented, since the sleeve pipe penetrates and is fixedly connected to the inner wall of the grinding chamber, a movable sleeve pipe is movably sleeved on the sleeve pipe. By connecting the feeding pipe to the movable sleeve pipe and moving the movable sleeve pipe above the second grinding disc, the raw materials to be ground can be conveyed onto the second grinding disc. By setting the movable sleeve pipe and the sleeve pipe, the supplement of raw materials can be realized in a closed state, which is beneficial to improving the overall airtightness of the device, effectively avoiding raw material pollution, and improving the overall reliability of the device.
