Efficient cooling and dust removal lifting tower

Abstract

The invention discloses a high-efficiency cooling and dust-removing lifting tower, comprising: a machine base, a material tray and a machine body, the material tray is fixedly installed on the machine base, and the machine body is fixedly installed in the material tray, and it is characterized in that: in the machine body The upper end is provided with a discharge port, and the lower end is provided with a feed port, which corresponds to the position of the material tray; a central column is provided in the middle of the inner cavity of the machine body, and a spiral trough is provided between the central column and the inner wall of the shell of the machine body , the spiral chute spirals up from bottom to top around the central column, and the head and tail are respectively connected with the discharge port and the feed port; the body is also equipped with a circulating cooling device, and the circulating cooling device is connected to the position of the spiral chute. Correspondingly; the bottom of the body is provided with two intersecting vibration motors, and the vibration motors are connected with the central column; the top of the body is also provided with a volute. The invention realizes the purpose of combining cooling, dust removal and lifting as a whole by adopting a structural form in which a circulating cooling device, an exhaust volute and a vibrating spiral trough are combined.

Description

technical field [0001] The invention relates to a granular material processing equipment, in particular to a high-efficiency cooling and dedusting lifting tower. Background technique [0002] Molding sand is a material used for modeling in casting. Molding sand is generally composed of raw sand for foundry, sand binder and auxiliary additives, etc. [0003] The molding materials are mixed in a certain proportion. Molding sand can be divided into clay sand, water glass sand, cement sand, resin sand, lost foam filling sand, etc. according to the different binders used. Clay sand, water glass sand, resin sand and lost foam filling sand are most used. Mold and sand play an extremely important role in casting production. The casting waste caused by poor quality of molding sand accounts for about 30-50% of the total casting waste. [0004] At present, in the molding sand processing equipment in the foundry industry, the configurations of fluidized bed plus drum air, water-cool...

AI Technical Summary

Problems solved by technology

Due to the short stroke of the molding sand in the fluidized bed during the whole process, the molding sand in the drum is piled up, resulting in poor thermal conductivity and uneven air cooling, so that the wind and water cooling cannot be fully utilized. At the same time, the equipment and site for molding sand processing are invested Huge, high energy consumption
