Winnowing device for removing fine particle dust of lime kiln and control method thereof

Abstract

The invention discloses a winnowing device for removing fine particle dust of a lime kiln and a control method thereof. The winnowing device comprises a feeding pipe and a winnowing box, wherein the winnowing box communicates with a discharging seat and a dust collecting pipe; and the tail end of the dust collecting pipe communicates with a fiber filter bag. The control method comprises the following steps of S1, starting an air pump firstly to convey generated airflow into an annular pipe through an air inlet pipe; and S2, and directly introducing the gas entering the annular pipe into a cover body through two connecting pipes above the annular pipe. The winnowing device has the advantages that air blown out from bottom to top can carry out winnowing dust removal on materials located in the screening box, meanwhile dust can be collected through cooperation of the fiber filter bag, so that the dust is prevented from drifting around along with movement of the materials, and meanwhile the part of resources (dust) can be conveniently collected and reutilized; and meanwhile, the materials placed in the screening box can be driven to turn over through airflow flowing, so that the dust can be subjected to winnowing removal more sufficiently.

Description

technical field [0001] The invention relates to the technical field of limestone production, in particular to a winnowing device for removing fine particle dust from a lime kiln and a control method thereof. Background technique [0002] Limestone needs to be heated to 1100°C for calcination in the lime kiln during the production process. However, during the production process of the lime kiln, a lot of small particles of dust will be generated. These small particles of dust are easy to disperse when moving with the finished ore, thus seriously It affects the working environment. At the same time, this part of the dust is limestone powder ore, which is directly scattered without causing recycling of resources. At the same time, some small particles of dust are easy to adhere to the finished ore (material) and are not easy to collect. Contents of the invention [0003] The purpose of the present invention is to solve the problems raised in the background technology, and pro...
