Wet sand drying device

Abstract

Disclosed is a wet sand drying device. The wet sand drying device comprises a drying cylinder. The drying cylinder is composed of two-layer cylinder walls. A heating chamber is formed between the inner side wall and the outer side wall. The right side of the drying cylinder is inclined upwards. A feeding inlet is formed in the upper portion of the left side of the drying cylinder, and a discharging outlet is formed in the lower portion of the right side of the drying cylinder; a steam inlet is formed in the lower portion of the left side of the drying cylinder, a steam outlet is formed in theupper portion of the right side of the drying cylinder, and the steam inlet is connected with a steam generator; a stirring shaft is arranged inside the drying cylinder, a spiral propeller is arrangedon the stirring shaft, and a motor for driving the stirring shaft to rotate is arranged at one side outside of the drying cylinder. According to the wet sand drying device, steam is adopted for heating the drying cylinder, the lowest temperature of the steam is higher than 100 DEG C, the drying cylinder can be efficiently heated, condensed water can continue to be used, resources are saved, heatexchange is completed, and heat energy can be supplied to other devices.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to a wet sand drying device. Background technique [0002] During the production of dry-mixed mortar, the moisture content of the raw material sand is required to be less than 0.5%. Most of the raw material sand cannot be directly used in the production of dry-mixed mortar because the moisture content is too high. Therefore, the raw material sand needs to be dried before use. Make its moisture content meet the conditions required for dry-mixed mortar production. Most of the existing wet sand drying devices have low drying efficiency, consume a lot of energy, and cause environmental pollution. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a wet sand drying device, which can improve drying efficiency and reduce environmental pollution and energy consumption. [0004] In order to solve the above technical problems, the t...
