Efficient combination type lifting device

Abstract

An efficient combination type lifting device relates to a lifting device of a rotary drum type drying machine which is used for the industrial fields of metallurgy, chemical engineering and the like. The efficient combination type lifting device comprises a drum body and multiple levels of combination lifting plates which are sequentially arranged on the inner wall of the drum body along the feeding direction of materials in the drum body, each level of the combination lifting plates comprises a plurality of arrays of lifting plates which are circularly arrayed on the peripheral inner wall of the drum body, the two adjacent arrays of lifting plates are staggered with each other along the radial direction, and the bending degree of the lifting plates in the next level of the combination lifting plates is increased compared with the previous level. Multiple levels of combination lifting plates are arranged in the drum body of the drying machine, a lifting plate mode is added, so that the materials with different properties on different parts of the drum body can reasonably exchange heat, and the heat exchange efficiency is increased; and moreover, the lifting device has the characteristics of difficulty in adhering materials, large drying water, small energy consumption and the like, and can be widely applied to the rotary drum type drying machine equipment in the industrial fields of metallurgy, chemical engineering, non ferrous, ceramsite, power plants and the like.

Description

technical field [0001] The invention relates to a lifting device for rotary drum dryers in industrial fields such as metallurgy, chemical industry, nonferrous metals, ceramsite, and power plants, in particular to a high-efficiency combined lifting device. Background technique [0002] At present, the lifting device used for rotary drum dryers is mainly the lifting plate on the inner wall of the cylinder. The lifting plate is generally made of bent steel plates. The structure and form of the lifting plate in the cylinder are relatively simple, and the cylinder The body length and the form of the lifting plate are not closely combined with the material properties and process requirements, resulting in insufficient drying efficiency and serious sticky materials inside the cylinder. Sometimes the outlet flue gas temperature is lower than the dew point temperature, causing harmful elements in the flue gas to enter the material, resulting in changes in the properties of the materi...

[0002] At present, the lifting device used for rotary drum dryers is mainly the lifting plate on the inner wall of the cylinder. The lifting plate is generally made of bent steel plates. The structure and form of the lifting plate in the cylinder are relatively simple, and the cylinder The length of the body and the form of the lifting plate are not closely combined with the material properties and process requirements, resulting in insufficient drying efficiency and serious sticking inside the cylinder

Sometimes the outlet flue gas temperature is lower than the dew point temperature, causing harmful elements in the flue gas to enter the material, resulting in changes in the properties of the material, corrosion of the equipment cylinder, and increased heat consumption.
