A dynamic water-sealed roller

Abstract

The invention discloses a dynamic water seal roller. The dynamic water seal roller comprises a roller; a free end of the roller is coated with a bearing and a bearing cover in sequence; a water inlet shaft pipe is sleeved in an inner hole of the roller; the end part of the roller is coated with a rotating joint; the rotating joint includes a shell; an outer pipe rotating body is sleeved in the shell; a hollow pipe is sleeved in the outer pipe rotating body; a water inlet and a water return port are formed in the shell; the water inlet is in butt joint with the water inlet shaft pipe through the hollow pipe; the outer pipe rotating body is coated with a shaft core; a cavity formed between the inner hole of the roller and the outer wall of the water inlet shaft pipe is communicated with a cavity formed between the inner wall of the outer pipe rotating body and the outer wall of the hollow pipe through the shaft core; and sealing rings are respectively sleeved between the shaft core and the inner hole of the roller and between the shaft core and the outer pipe rotating body. The dynamic water seal roller realizes cooling of the roller during roller rotating, prevents high-temperature damage of the roller and the bearing, prolongs the service life of the roller, is provided with multiple sealing rings in the rotating joint to achieve a dynamic water seal effect in a cooling system joint, and reduces leakage of cooling water.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a dynamic water-sealed roller. Background technique [0002] The segment of the slab continuous casting machine is mainly to support and transport the slab that has formed a solid slab shell or completely solidified, and prevent the slab shell from bulging deformation under the action of the hydrostatic pressure. Because the temperature of the slab is very high, and the sector-shaped rollers mainly support the slab, the high-temperature slab will easily damage the surface of the roller and the bearing due to high temperature, which will affect the service life of the roller. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dynamic water-sealed roller for the above-mentioned defects in the prior art, which can cool down the roller while the roller is rotating, so as to avoid damage to the roller and be...
