Embodiment 1

[0050] see Figure 3 to Figure 8 , a winnowing device for removing fine particle dust from a lime kiln according to an embodiment of the present invention. Wherein, the top of the cylinder 10 is provided with an air outlet 11, and the top of the cylinder 10 is provided with a feed inlet; the rotating reflective plate winnowing mechanism 20 includes a rotating reflective grate 21 arranged in the cylinder 10, and the rotating reflective grate 21 is provided with a plurality of air distribution holes 211, one end of the rotating reflective grate 21 is installed on the side wall of the cylinder 10, the other end of the rotating reflective grate 21 is a free end, and a rotating motor is installed on the outer wall of the cylinder 10 22, the output end of the rotating motor 22 is connected to the rotating reflective grate 21 through the rotating coupling 23; the air inlet device 30 is installed on the lower part of the cylinder 10 and is located below the rotary reflecting plate win...

Embodiment 2

[0076] see Figure 2 to Figure 8, a lime kiln according to an embodiment of the present invention, the lime kiln includes a kiln body 100, the lower part of the kiln body 100 is provided with a lime kiln discharge port 110, and the lime kiln is also provided with the winnowing removal device according to Embodiment 1 of the present invention , The discharge port 110 of the lime kiln is connected with the feed port in the winnowing removal device through a material chute 120 . The structure of the winnowing removal device is the same as that of Embodiment 1, and will not be repeated here.

[0077] Generally speaking, by adopting the winnowing device of the present invention and the lime kiln with the winnowing device, a large amount of dust such as lime powder ore and residue after pulverized coal burning contained in the finished lime ore can be effectively taken away by high-speed wind; When discharging, the fine particle dust will not be scattered and splashed at the discha...

Abstract

The invention discloses a winnowing device for removing fine particle dust of a lime kiln, a control method and the lime kiln. The winnowing device comprises a barrel, a rotary reflection plate type winnowing mechanism and an air inlet device. An air outlet is arranged at the top of the barrel, and a feeding opening is arranged on the upper portion of the barrel. The rotary reflection plate type winnowing mechanism comprises a rotary reflection grate plate arranged in the barrel, multiple air distribution holes are formed in the rotary reflection grate plate, one end of the rotary reflection grate plate is mounted on the side wall of the barrel, the other end of the rotary reflection grate plate is a free end, a rotary motor is mounted on the outer wall of the barrel, and the output end ofthe rotary motor is connected with the rotary reflection grate plate through a rotary coupling. The air inlet device is mounted on the lower portion of the barrel and located below the rotary reflection plate type winnowing mechanism, and the air inlet device is used for blowing airflow into the barrel. According to the winnowing removal device and the lime kiln, the existing problems that duringdischarging of the lime kiln, environment pollution is severe, and waste of ore fine resources is severe are solved effectively.

Description

technical field [0001] The invention relates to the technical field of lime production equipment, in particular to a winnowing device and control method for removing fine particle dust from a lime kiln, and a lime kiln. Background technique [0002] Lime is an important auxiliary raw material widely used in the metallurgical industry. In the sintering of ironmaking raw materials, ironmaking reduction process, molten iron pretreatment process and out-of-furnace refining process, lime is used as an additive to adjust the alkalinity of the charge, slagging and desulfurization, etc., which is of great importance to the smooth progress of ironmaking and steelmaking processes important role. [0003] The lime kiln is the core equipment in the lime production process. The raw limestone is heated to 1100°C in the lime kiln and calcined to produce the product lime. At present, the widely used lime kiln kiln type is mainly vertical kiln (see figure 1 ). Lime kiln production proces...
