Description

Technical Field

[0001] The utility model belongs to the technical field of cast steel coatings, and in particular relates to a cast steel coating dust removal device. Background Art

[0002] Casting coating is a casting auxiliary material that covers the surface of the core during the casting process to improve its surface fire resistance, chemical stability, resistance to metal liquid erosion, resistance to sand adhesion and other properties; casting coating can be made into slurry, paste or powder, and applied to the surface of the core by spraying, brushing, immersion, flow and other methods; the coating thickness of dip coating can be controlled by coating concentration, dipping times and controlling dipping operation; generally two dipping operations are used: the first time, dipping a thin coating with a lower concentration to obtain a uniform thin coating and improve the coating performance of the two operations; the second time, the coating concentration must be adjusted to obtain a uniform coating thickness; if the coating concentration does not change and the coating thickness is required to be controlled, it can only be adjusted by shaking the lost foam mold several times after dipping; it is generally not difficult for a skilled coating worker to meet this requirement;

[0003] Application No. 202221366329.6 provides a dust removal device for cast steel coating production.

At the same time, the cylinder reset can drive the piston rod reset, so as to automatically reduce the dust suction aperture, so as to reduce the overall volume of the dust hood to facilitate storage. Through its design, the dust suction range can be adjusted. By arranging a clamping sleeve and a pullable clamping rod at the top of the piston mechanism, when the cylinder is connected to the piston mechanism through the groove block, the clamping rod can be clamped into the groove block to quickly fix the cylinder and the piston mechanism, and the clamping rod can be fixed by the adsorption of the magnet and the clamping sleeve to prevent the piston mechanism from separating from the cylinder. Through its design, the cylinder and the piston mechanism are easy to disassemble;
