Abstract

The invention discloses a preparation device and a preparation method of heat-preservation deslagging sand for molten metal, and belongs to the technical field of heat-preservation deslagging sand preparation.The preparation device comprises a supporting frame, a disc granulator is arranged on one side of the upper end of the supporting frame, a fixing frame is arranged on the other side of the upper end of the supporting frame, and a stirring barrel is arranged at the upper end of the fixing frame; a feeding hopper is arranged at the upper end of the stirring barrel, a drying box is arranged in the middle of the supporting frame, and a screening box is arranged at the bottom of the supporting frame; filtering and screening are carried out through all layers of screens, screened ceramsite is discharged from discharging openings in the side edges in sequence and falls into respective collecting boxes, a motor rotates to drive a shaft rod to rotate, the shaft rod drives a driving bevel gear to rotate, the driving bevel gear drives a driven bevel gear to rotate, and a screw rod where the driven bevel gear is located rotates; the screw rotates to enable the moving plate to slide in the screening box, the cleaning brush at the lower end of the moving plate moves to clean ceramsite on the surface of the screen, and inconvenience in filtering caused by blockage is avoided.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation deslagging sand preparation, and in particular relates to a preparation device for thermal insulation deslagging sand for molten metal and a preparation method thereof. Background technique [0002] Ceramsite, as the name suggests, is the particle of pottery. Most of the appearance characteristics of ceramsite are round or elliptical spheres, but there are also some imitation gravel ceramsites that are not round or elliptical spheres, but are irregular crushed stones. [0003] The shape of ceramsite varies with different processes. Its surface is a hard shell, which is ceramic or enamel, which has the function of water-proof and gas-retaining, and endows the ceramsite with high strength. [0004] The prior art has the following problems: the existing thermal insulation and deslagging sand preparation device for molten metal has the following problems: 1. It is inconvenient to screen, ...
