Differential rotation drive device

Abstract

The invention relates to a differential rotation drive device which comprises an inner barrel body, an inner barrel body flange, an outer barrel body and an outer barrel body flange, and further comprises a rotation device. The inner barrel body flange is connected with a rotation device inner ring through a first bolt, the outer barrel body flange is connected with the rotation device outer ring through a second bolt, a roll ball is arranged in a groove of the inner ring and the outer ring of the rotation device, screen holes are arranged on the surface of the outer barrel body, and a sealing device is arranged between the inner barrel body and the outer barrel body. By adopting the structure mentioned above, cooling and drying of materials and screening of the materials can be finished through one device, work efficiency is improved, maintenance cost and energy consumption are reduced; and meanwhile waste gas and powder discharging and environment pollution are reduced.

Description

technical field [0001] The invention relates to slewing equipment in the metallurgy and cement industries, in particular to a differential slewing drive device. Background technique [0002] Materials in metallurgy and cement industries need to be screened, crushed and other processes after being cooled and dried in the rotary equipment. The existing rotary equipment can only provide a single rotating speed, and the rotating speed is low. When the material is cooled and dried, generally a low rotating speed is required to make the material pass through the rotary equipment slowly, so as to achieve the ideal cooling or drying effect. However, material screening generally requires a higher speed, and the ideal screening effect can only be achieved by bringing the material to a certain angle of lift. Under the existing technical conditions, two sets of equipment are needed to complete cooling, drying and screening, and materials need to be conveyed between the two sets of equi...

Problems solved by technology

In this link, because the material contains dust, it will cause great harm to the environment and the body of the operator.

Some dried materials also have a higher temperature and higher requirements on the conveying equipment, which not only increases the cost of the equipment, but the equipment itself is also limited by the space of the site.
