Novel rotary kiln with three-gear-supported super-short kiln body

Abstract

The invention discloses a novel rotary kiln with a three-gear-supported super-short kiln body. The novel rotary kiln comprises the rotary kiln body, bases and supporting devices. The length of the rotary kiln body ranges from 52 m to 55 m, the diameter of the rotary kiln body ranges from 4.6 m to 5 m, and the rotary kiln body is a short kiln with the length-diameter ratio smaller than 13. Each ofthe number of the bases and the number of the supporting devices is three. The whole rotary kiln body is fixed to the three bases through the three supporting devices. Because the length-diameter ratio of the three-gear short kiln is small, the thermal radiation, convection and conduction effects in the kiln are all superior to those of a conventional three-gear long kiln; and therefore the gas speed in the kiln is smaller than that of a conventional rotary kiln, recirculation of clinker dust in the kiln is reduced, the unit volume yield is improved, and the electricity consumption and heat consumption of the system are lowered.

Description

technical field [0001] The invention belongs to the field of building materials and equipment, and in particular relates to a novel rotary kiln with a three-stage support ultra-short kiln body used for increasing production and reducing consumption of a cement production line. Background technique [0002] With the continuous deepening of my country's industrial structure adjustment, energy saving and consumption reduction has become a new impetus for the development of the cement industry. Only by continuously carrying out technological innovation, improving product quality, and reducing production energy consumption can existing cement enterprises obtain long-term survival. And development. However, many enterprises with low output and high energy consumption are facing the embarrassing situation of being eliminated due to the limited space of the original production line and the huge financial pressure brought about by conventional transformation. A new type of rotary kil...

AI Technical Summary

Problems solved by technology

The short kiln adopts two-stage support, and the long kiln adopts three-stage support. With the continuous deepening of national energy-saving and consumption-reducing requirements, many cement enterprises want to improve their production efficiency by increasing production and reducing consumption, but most enterprises adopt three-stage support. The long-range kiln is limited by the site. If it is to increase production and reduce consumption, almost all the original production lines must be demolished and rebuilt, and the cost of renovation is too high.
