Description

TECHNICAL FIELD

[0001] The utility model relates to four roll centrifuge field, concretely is a kind of direct coupling four roll centrifuge for rock wool production. BACKGROUND

[0002] In the production process of rock wool, four roll centrifuge plays a vital role. Rock wool is a high-quality thermal insulation, sound-absorbing material, its production process involves melting high-quality natural rock at high temperature, and forming rock wool fiber through fiberization treatment. Four roll centrifuge is the core equipment in this fiberization process.

[0003] Direct coupling four roll centrifuge is a high-efficiency separation equipment, compared with four roll centrifuge, direct coupling four roll centrifuge is more compact in structure, and more convenient to operate, the working principle of direct coupling four roll centrifuge also depends on the centrifugal force generated by high-speed rotation. When the centrifuge starts, the four rollers rotate at high speed, generating strong centrifugal force. Under the action of this force, different components in the material will be separated to different positions according to their density and mass difference. Heavy components will be close to the periphery, while light components will tend to the center, so as to realize effective material separation.

[0004] In the working process of the existing direct coupling four roll centrifuge, the raw materials are usually poured directly onto the top of the centrifugal roller. In use and observation, it is found that the slag components in the raw materials will directly contact with the high-speed rotating centrifugal roller. This contact will cause gradual wear of the surface material of the centrifugal roller, and further affect the centrifugal effect of the centrifugal roller.

[0005] Therefore, a direct coupling four roll centrifuge for rock wool production is proposed to solve the above problems. UTILITY MODEL CONTENT
