Cupola

Abstract

The invention provides a cupola. The cupola is simple in structure and convenient to machine and operate, and distribution evenness is improved. The cupola comprises a cupola body, a feeding opening is formed in the middle of the top of the cupola body, and a conveying belt is arranged above the feeding opening. A distributing mechanism is arranged in the cupola body and sequentially comprises a conical funnel, a counter weight and a pair of symmetric push plate mechanisms. The conical tip of the funnel is arranged upwards, and the funnel is connected to the bottom face of the top of the cupola body through a pair of first connecting rods. The counter weight is connected to the center of the bottom face of the funnel through a second connecting rod. The push plate mechanisms comprise hydraulic cylinders and push plates, the hydraulic cylinders are fixedly arranged on the inner wall of the cupola body, the push plates are movably arranged on the inner wall of the cupola body, and the hydraulic cylinders horizontal move to push the push plates. The push plates in the push plate mechanisms are symmetrically located on the two sides of the counter weight. According to the cupola, the wool output rate is increased, and the quality of finished rock wool is improved.

Description

technical field [0001] The invention relates to a material distributing mechanism of a cupola. Background technique [0002] The cupola is the ore raw material melting equipment in the production of rock wool. The particle size of the ore raw material in the cupola is generally not the same, and the size of the particle size will affect the size of the combustion-supporting wind resistance in the cupola, so the feeding cloth of the cupola The basic requirement is that ore raw materials with large and small particle sizes can be homogenized and stacked in the cupola. [0003] In the prior art, the feeding material in rock wool production is only lifted by the hoist to the top of the cupola and directly put into the furnace. Because the ore raw material with larger particle size has a greater rolling capacity, the larger ore raw material after feeding Generally, they are stacked around the wall of the cupola cylinder and at the bottom, while ore materials with smaller particl...

Problems solved by technology

This makes the melting rate of the raw materials different near the bottom coke, which affects the stability of the furnace condition, and the flow rate of the melt out of the furnace fluctuates greatly, resulting in a decrease in the cotton yield and uneven thickness of the cotton filaments, which affects the quality of rock wool products.
