Rotary kiln shell with forward and reverse bidirectional rotation

Abstract

The invention relates to a positive-negative two-way rotating rotary kiln shell. The positive-negative two-way rotating rotary kiln shell comprises a rotary shell, multiple groups of two-way fixed spring pulling plates and a bull gear, wherein the rotary shell has two rotating directions including positive rotation and negative rotation; the multiple groups of two-way fixed spring pulling plates are arranged on the rotary shell; each group of two-way fixed spring pulling plate further comprises a positive fixing part and a negative fixing part; one end of each positive fixing part is fixedly connected with the outer wall of the rotary shell; the other end of each positive fixing part is arranged along one of the two rotating directions in an extending manner; one end of each negative fixing part is fixedly connected with the outer wall of the rotary shell; the other end of each negative fixing part is arranged along the other rotating direction of the two rotating directions in an extending manner; the bull gear is detachably connected with the other ends of the positive fixing parts and the other ends of the negative fixing parts in all groups of two-way fixed spring pulling plates. The rotary kiln shell disclosed by the invention and the bull gear are connected by the multiple groups of two-way fixed spring pulling plates, so that the connecting strength of the rotary kiln shell and the gear is enhanced.

Description

technical field [0001] The invention relates to a rotary kiln cylinder, in particular to a rotary kiln cylinder that rotates in both forward and reverse directions. Background technique [0002] Rotary kiln, also known as rotary kiln, is a cylindrical object with a certain slope, with a slope of 3-3.5%. The rotation of the kiln promotes the stirring of the materials in the rotary kiln (rotary kiln), so that the materials are mixed with each other, contact to react. The coal injection combustion at the kiln head generates a lot of heat, and the heat is transferred to the material by the radiation of the flame, the convection of the hot gas, and the conduction of the kiln brick (kiln skin). The material moves forward in the kiln depending on the inclination of the kiln cylinder and the rotation of the kiln. It has a wide range of applications in technical fields such as material drying and calcination. In some applications, the cylinder of the rotary kiln needs to be arrang...

Problems solved by technology

At the same time, the tire is a part that strengthens the radial rigidity of the cylinder and should have sufficient rigidity. However, during the working process of the forward and reverse rotary kiln, when the rotary kiln cylinder is deformed, it will lead to the rotation of the rotary kiln cylinder. Efficiency and rotation will cause serious accidents such as stagnation or severe sliding. Therefore, after the rotary kiln cylinder has been running for a period of time, if the gap between the wheel belt and the backing plate on the cylinder is too large due to wear, it is necessary to add or replace the backing plate on site. It can only be installed and continue to work if it meets the rotation requirements

[0007] Therefore, to sum up, for the rotary kiln that needs to achieve forward rotation and reverse rotation at the same time, the cylinder needs to be repaired regularly or on demand during the operation process. The entire body is disassembled and dragged to a site that meets its machining requirements for processing and supplementary deformation positions. The entire cycle is longer, and the construction period is delayed and costs are wasted. The drying efficiency is also low, and the cost and cost are relatively high.
