Abstract

The invention provides a rocking kiln arranged in the shape of an inclined barrel and driven by a driving mechanism to rotate and rock side to side; material enters from a feed end that is high, to bespecific, the material rolls along the periphery and moves axially toward a discharge end that is low. Burners and nozzles may be arranged radially in the middle of the kiln where the material is calcined and heated, and heat that is generated may be transmitted from the middle of the kiln to a head of the kin and is finally guided into a dust remover for centralized treatment. According to the technical scheme, a calcining portion is arranged in the middle of a kiln barrel; flexible adjustments can be made according to kiln length during calcining; a thermocouple has higher temperature control precision; zonal control can be provided so that control precision for a material heating process curve is increased to + / - 2 DEG; waste gas is guided out of the head, centralized collection of thewaste gas is achieved, and raw material that is not heated can be preheated to certain degree; the calcining process is accompanied by roll-conveying of the material, the heating mode is more uniform, and energy utilization rate is increased.

Description

technical field [0001] The invention relates to the technical field of calcination equipment, in particular to a swing kiln. Background technique [0002] A kiln is an industrial device used to perform calcination operations. The kilns used for calcination of powder or particles in the prior art mainly include rotary kilns, shuttle kilns, roller kilns, tunnel kilns, etc. Among them, shuttle kiln, roller kiln, tunnel kiln and other structures are relatively simple, but they need bowl-shaped containers. During the calcination process, the materials are not heated uniformly, and problems such as undercooking and over-burning are prone to occur. Relatively speaking, the application of rotary kiln is more common. Its main structure includes an inclined and horizontal rotary cylinder. Raw meal powder is fed from the higher end, and fuel is burned at the lower end. The material is heated while moving, so as to play a role. The role of calcination. Although the problem of uneven h...
