Manganese processing rotary kiln system with bag dust removal type for easy disassembly of induced draft fan

Abstract

The invention discloses a bag filter-type manganese processing rotary kiln system with a highly demountable induced draft fan. The bag filter-type manganese processing rotary kiln system adopts the structure that an air-lock valve used for feeding is arranged at the high end of a rotary kiln; the high end of the rotary kiln is connected with a cyclone dust extractor, an induced draft fan and a bag-type dust remover via a fin section and air pipes; fins are arranged in the fin section; a hood cylinder is arranged outside the fin section; a sleeve-type air heat exchanger is arranged outside an air pipe; the hood cylinder is communicated with a lower pumping hole in the air heat exchanger, and then divided into two paths for supplying preheated air; and the blades of the impeller of the induced draft fan are arranged in a radiation shaped and are in radial and central symmetry with respect to an impeller shaft, so that dust can be cleaned promptly via centrifugal force, and safety accidents can be avoided. The bag filter-type manganese processing rotary kiln system not only is high in heat efficiency, but also has the advantages that the demounting technology of the induced draft fan is greatly improved; pressure of a nut-like component on a shaft shoulder end surface of a screw can be eliminated simply during demounting, the problem that a threaded assembly of the induced draft fan is automatically screwed continuously under the action of a load to be difficult to demount can be solved effectively; the suitability for convenient demounting of a large-scale induced draft fan after thread screwing is high; and the effect is remarkable.

Description

technical field [0001] The invention relates to a manganese processing rotary kiln system, in particular to a cloth bag dust removal type manganese processing rotary kiln system which does not accumulate dust in a fan and is easy to disassemble. Background technique [0002] Due to its strong adaptability, low operating cost and high reliability, the rotary kiln is one of the main preferred equipment for mineral batching, pelletizing, reaction and drying, especially suitable for the processing and burning of manganese ore. During the working process, the rotary kiln needs to consume fuel to maintain a suitable high temperature in the kiln. Therefore, the exhaust gas discharged from the rotary kiln contains a lot of heat energy and dust. It is necessary to purify the exhaust gas and recover the exhaust heat to achieve energy saving and emission reduction. [0003] The rotary kiln is generally cylindrical, so the heat transfer area between the material and the kiln body is ver...

AI Technical Summary

Problems solved by technology

In the actual assembly of shafts and holes with transmission threads, in order to achieve large load-bearing functions, the size of the threaded shafts and matching nut-like components are relatively large, and it is often easy and convenient to screw in during assembly, and It can realize the automatic and continuous locking of the bearing capacity during use, so it is very reliable, but when it is disassembled, the assembly is often very tight, and disassembly is very difficult. It is particularly important to realize simple and easy disassembly under this condition
