Abstract

The invention provides a zigzag cooling mechanism. The zigzag cooling mechanism comprises a lifting device and a discharging slideway, wherein a feeding opening is formed in the lower end of the lifting device; a discharging opening is formed in the upper end of the lifting device; the lifting device lifts to-be-cooled precoated sand to certain height; the discharging opening of the lifting devicecorresponds to the discharging slideway; a discharging channel comprises a material receiving hopper and a plurality of discharging skid hoppers; an upper end opening of the material receiving hoppercorresponds to a discharging opening in a housing; the plurality of discharging skid hoppers are connected end to end and are vertically arranged into a zigzag structure; a lower end opening of the material receiving hopper corresponds to the uppermost discharging skid hopper; during use, the falling stroke of the precoated sand is increased by a discharging channel with a zigzag structure, so that contacted area between the precoated sand and air is enlarged, falling time of the precoated sand is prolonged, and the precoated sand is enabled to be in full contact with the air and sufficientlycooled.

Description

technical field [0001] The invention belongs to the technical field of equipment for producing coated sand, and in particular relates to a zigzag cooling mechanism. Background technique [0002] The coated sand casting process is a mixed method of coated sand, which has gone through four stages: dry mixing method, cold coating method, warm coating method, and hot coating method. The production of coated sand is almost always using the hot coating method. , The thermal coating process is to heat the raw sand to a certain temperature, then mix it with resin, urethane solution and calcium stearate, and then cool, crush and sieve it. The cooling step generally uses a vibrating screen for cooling. This cooling method uses an electric loading device. This type of device is always in an electric state, which virtually increases the cost. Contents of the invention [0003] Aiming at the technical problems existing in the cooling of the existing coated sand, the present invention ...
