Gas jet impact type revolving drum drying and curing integrated machine

Abstract

The invention discloses a gas jet flow impact type tumbler heating and baking integrative machine, combines the gas jet flow impact heating and baking technology with the tumbler drying technology. The invention comprises a cylinder cover (1), a cylinder body (2), an airflow distribution room (3), an air access central pipe (5), a bearing and bearing sleeve mechanism (7), a ventilation device (8), a temperature and humidity sensor (9), air access elbow pipe sections (10, 11), air access straight pipe sections (12, 14), a heating device (13), a machine frame (15), air access spiral cases (16, 17), a fan mechanism (18), a speed reducer (19), a chain drive mechanism and a supporting roller mechanism (25). The integrative machine is characterized in that the material is heated evenly, and the heat utilization rate is high. The integrative machine takes the air as heating medium, adopts the pipeline design which can recycle the hot air, is clean, can protect environment and save energy, can flexibly adjust the diameter, inclination angle and height of the orifice according to the size of the material, has strong adaptability to the material, and has bi-service obvious economic benefit of drying and baking.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to a gas jet impingement drum drying and baking integrated machine. Background technique [0002] Gas jet impact drying and baking technology is a drying and baking method in which heated gas with a certain pressure is ejected through a nozzle of a certain shape and directly impacts the material. As the gas is a low-quality fluid, it is used as a medium to impact the processed materials, which can adapt to materials with large differences in particle size, shape and density. Utilizing this technology, the horizontal gas jet impingement oven disclosed in Chinese patent 02238211.9 can be used for drying and baking of various materials, but its disadvantage is that only one layer of materials is laid flat on the material tray, and the processing capacity is small. [0003] Rotary drum dryer is one of the most widely used drying equipment in the world. The conventional rotary drum drye...
