Tower type hot air dryer

Abstract

The invention belongs to the field of air drying equipment, and particularly relates to a tower type hot air dryer. An air drying chamber (21) comprises a heat preservation wall (13), a net-shaped tray (12), a motor (11) and a main shaft (16) longitudinally linked with the motor (11). A hot air circulation part comprises an air cooler (3), an induced draft fan (2), an electromagnetic induction heating module and a heating medium distributor (20). A refrigerant outlet of the air drying chamber (21) communicates with a refrigerant inlet of the electromagnetic induction heating module through theair cooler (3) and the induced draft fan (2). A heating medium outlet of the electromagnetic induction heating module communicates with a heating medium inlet of the heating medium distributor (20) through a ventilation pipeline (10) and an exhaust fan (9). A heating medium outlet of the heating medium distributor (20) communicates with a heating medium inlet of the air drying chamber (21). The tower type hot air dryer is ideal in energy-saving effect, flexible in drying range, high in parameter controllability, convenient to automatically control, good in dried product quality, environmentally friendly and free of noise.

Description

technical field [0001] The invention belongs to the field of air-drying equipment in the fields of industry, agriculture, medicine, etc., and in particular relates to a tower-type hot-air air-drying machine. Background technique [0002] The traditional way of adding radiators to coal-fired heating furnaces in my country has low fuel heat conversion efficiency, large soot emissions, and serious environmental pollution. So in the late 1970s and early 1980s, heat pump technology began to emerge. As a drying technology that transfers low-level heat sources to high-level heat sources, heat pump drying has almost no impact on the environment and has a good energy-saving effect; it has a wide range of drying; it is convenient for automatic control and has strong parameter controllability; More friendly and other advantages. It is in line with the current energy policy and development trend, so it soon became a hot spot for scholars at home and abroad. Its working principle is t...

Problems solved by technology

At the same time, the heat exchange of the air source heater adopts the form of a fan, which is noisy and prone to static electricity, and a large compressor needs to be installed outdoors

In addition, since the "two combined supply" system is composed of products provided by many different equipment manufacturers, and involves professional technical knowledge in various fields of water, heating, cooling, and electricity, the system structure is complex, there are many materials and supporting products, and the integration and installation are cumbersome. The after-sales commissioning work is also more complicated, and the construction plan is often changed due to unforeseen factors, and the construction cost is increased due to rework, so the project cost determined by the budget is often exceeded, which has a certain impact on its sales
