Granular wool manufacturing system

Abstract

The invention discloses a granular wool manufacturing system and aims to provide the granular wool manufacturing system which not only can fully utilize residual heat resources in blast furnace thermal-state slag and is energy-saving and environmental-protective but also can enable a melt in a slag furnace to be melted uniformly, a vitrification degree to be high and a fiber-forming ratio and quality of mineral wool to be improved. The device includes a slag furnace, a four-roller centrifugal machine and a wool-collecting machine. The slag furnace successively includes a feeding tank, a homogenizing tank, a melting tank and a material path. A slag flow inlet and a main modulating material feeding port are arranged on an upper part of the feeding tank. The bottom of the feeding tank is connected to the bottom of the homogenizing tank through a first liquid flowing path. The bottom of the homogenizing tank is communicated with the bottom of the melting tank through a second liquid flowing path. One end of the material path is communicated with the melting tank and the other end of the material path is closed. In addition, a material outlet port is arranged at the bottom of the material path. The four-roller centrifugal machine includes a centrifugal machine shell and four centrifugal rollers arranged inside the centrifugal machine shell, wherein external surfaces of the centrifugal rollers are respectively provided with spiral grooves surrounding the centrifugal rollers.

Description

technical field

[0001] The invention relates to the field of mineral wool production, in particular to a granular cotton preparation system. Background technique

[0002] Mineral wool uses industrial waste slag (blast furnace slag, etc.) Under the action of the centrifugal force generated by the roller, it is thrown into mineral wool fibers; at the same time, the mineral wool fibers are blown into the cotton collector with the high-speed airflow ejected from the wind ring in the centrifuge (the high-speed airflow ejected from the air ring is on the centrifugal roller shaft. Upward, high speed flow along the surface of the centrifugal roller). The mineral wool fiber in the cotton collector gathers on the mesh belt of the cotton collector under the action of negative pressure wind suction to form a mineral wool felt. Mineral wool has the characteristics of light weight, small thermal conductivity, non-combustible, moth-proof, cheap, corrosion-resistant, good chemical stabili...
