Equipment for recycling molding sand and clearing inside and outside of centrifugal cast mold tube of turbine

Abstract

The invention discloses equipment for recycling molding sand and clearing inside and outside of a centrifugal cast mold tube of a turbine. The equipment comprises an external dust collecting device, an inner wall clearing device and a molding sand recycling device; the inner wall clearing device comprises a moving component and a grinding component, wherein the moving component is used for moving the cast mold tube, and the grinding component is used for clearing the cast mold tube. The external dust collecting device comprises a motor for driving a main shaft; a sun gear sleeves the main shaft and is mounted on a planet carrier; a rotary disc is mounted on a connecting disc in a sliding manner; a bayonet is also abutted with a dustproof cover. The molding sand recycling device comprises a conveying belt for conveying sand for casting; a pair of grinding wheels opposite in rotation direction is arranged below the conveying belt; a three-stage vibrating screen is used for receiving a material falling from a two-stage separating plate, separating the relatively-coarse material into a sand recycling container and separating the relatively-thin waste material into a second collecting container. The equipment disclosed by the invention is simple in structure and capable of greatly improving the stability in grinding.

Description

technical field [0001] The invention relates to a casting production equipment, in particular to a turbine centrifugal casting mold cylinder internal and external cleaning and molding sand recovery equipment. Background technique [0002] Casting is a kind of metal thermal processing technology mastered by human beings earlier, with a history of about 6,000 years. China has entered the heyday of bronze castings between 1700 BC and 1000 BC, and the craftsmanship has reached a very high level. Casting is a method in which liquid metal is poured into a casting cavity adapted to the shape of the part, and after it is cooled and solidified, the part or blank is obtained. The material to be cast is mostly a metal that was originally solid but heated to a liquid state (for example: copper, iron, aluminum, tin, lead, etc.), and the material of the mold can be sand, metal or even ceramics. Depending on the requirements, the methods used will vary. [0003] Casting is the process o...
