Melting furnace for rock wool production

Abstract

The invention discloses a melting furnace for rock wool production. The furnace includes a cylindrical melting furnace body, the wall of the melting furnace includes an inner wall body and an outer wall body, an annular channel is formed between the inner wall body and the outer wall body, the bottom of the annular channel is provided with an annular water tank, and the annular channel is communicated with the annular water tank through a through hole; the top of the melting furnace is provided with a feeding hole which is connected with a feeding system; the side face of the melting furnace is provided with a discharge hole, a liquid level meter is arranged at the discharge hole, an air inlet is arranged on the bottom of the melting furnace, and the air inlet is connected with an air intake system; the feeding system, the liquid level meter and the air intake system are electrically connected with a control system. The air intake system, the feeding system, the liquid level meter areconnected with the control system, feeding and air intake of the combustion furnace can be automatically controlled according to the combustion situation of materials in a combustion furnace and the discharge situation of the discharge hole, the continuous production operation of the combustion furnace is effectively ensured, the production efficiency is improved, the cost is saved and the overallbenefit of the rock wool production is improved.

Description

technical field [0001] The invention relates to the technical field of rock wool production equipment, in particular to a melting furnace for rock wool production. Background technique [0002] Rock wool is a common thermal insulation material. Raw materials such as basalt, coke, dolomite and slag are melted, centrifuged to make them fibrous, and then further processed to form rock wool boards or other products. With the development of the national economy and the implementation of the national energy-saving policy, the demand for rock and mineral wool products for building and industrial thermal insulation is increasing. However, the existing domestic cupolas for the production of rock and mineral wool are generally traditional Jacketed shaft furnace, the cooling water is passed into the middle jacket, the temperature of the cooling water rises after passing through the melting furnace, and it is cooled by the cooling tower. After cooling, the water is passed into the jacke...

With the development of the national economy and the implementation of the national energy-saving policy, the demand for rock and mineral wool products for building and industrial thermal insulation is increasing. However, the existing domestic cupolas for the production of rock and mineral wool are generally traditional Jacketed shaft furnace, the cooling water is passed into the middle jacket, the temperature of the cooling water rises after passing through the melting furnace, and it is cooled by the cooling tower. After cooling, the water is passed into the jacket of the melting furnace to cool the furnace wall Cool down to ensure that the furnace wall will not be melted and deformed. In this way, water heat energy is wasted during the water circulation process. At the same time, a large amount of electric energy is used to drive the motor for blowing and water pump circulation, resulting in 80% energy waste, which does not meet the needs of energy conservation and environmental protection.

In addition, most of the existing melting furnaces are artificially and actively fed according to the combustion of raw materials, and the production efficiency is low
