Novel rotary kiln

Abstract

The invention relates to a novel double-barrel rotary kiln, comprising a barrel body, a feeding part, a discharging part and a rotary part, wherein the feeding part comprises a feeding tube, the barrel body comprises an inner barrel and an outer barrel, one end of the outer barrel is provided with an end plate, one end of the inner barrel is positioned in the outer barrel and is supported by an inner barrel supporting tube, and the inner barrel is disconnected with the outer barrel; the other end of the inner barrel is supported by a supporting roller, and the supporting point lies in a plane. The inner barrel is provided with a big head and a small head, and a 0.1-0.2% gradient is formed. The inner-outer double-barrel structure elongates travel distance or material in the kiln. An spacing plate inclining downwards is disposed in the feeding tube make the wet material to be processed smoothly get through the feeding tube and the outer barrel, turn to the inner barrel and sufficiently reversely exchange with the high temperature hot gas flow, thereby realizing drying and dehydration by using a small quantity of energy source.

Description

technical field [0001] The invention relates to equipment for drying and calcining water-containing materials, in particular to a rotary kiln. Background technique [0002] In the calcination and drying process of cement, gypsum, and some chemical and building materials industries, the traditional process uses a single-cylinder rotary kiln, which is relatively simple and low in cost, but has high energy consumption, low efficiency, and large investment when the journey is long. There is also a patent for "double-layer rotary kiln", but in fact it is still a single-cylinder kiln, but a double-layer kiln head is added in front of the single cylinder. Contents of the invention [0003] The technical problem solved by the invention is to provide a rotary kiln with low investment and energy saving. [0004] The technical solution of the present invention is: a rotary kiln, including a cylinder, a feeding part, a discharging part and a transmission part, wherein the feeding par...
