Abstract

The invention discloses a drying device for heating by combining medium wave with jet, comprising a control part and a body (1), wherein the body (1) comprises a transmission band which successively comprises a feed section (2), a heating section (3) and a discharging section (4); a heating and drying device is arranged on the heating section (3) and successively comprises an IR1 medium-wave heating device (5), an air knife jet heating device (6), an IR2 medium-wave heating device (7) and an IR3 medium-wave heating device (8); heating tube stacks are respectively arranged in the IR1 medium-wave heating device (5), the air knife jet heating device (6), the IR2 medium-wave heating device (7) and the IR3 medium-wave heating device (8); the IR1 medium-wave heating device (5), the air knife jet heating device (6), the IR2 medium-wave heating device (7) and the IR3 medium-wave heating device (8) cover the upper part of the transmission band and are opposite to the transmission band.

Description

technical field [0001] The invention relates to a drying device with medium wave and spray combined with heating. Background technique [0002] China is one of the countries with the lowest per capita energy reserves in the world. Per capita energy consumption is only half of the world average. But on the other hand, China's current energy utilization rate is only about 30%, which is about 10 percentage points lower than that of developed countries. The energy consumption of output value is more than 2 times higher than the world's average level, and more than 10 times that of Germany, making it one of the countries with the highest energy consumption of output value in the world. Therefore, "saving energy and protecting the environment" has become the top priority of government work. At present, energy saving and consumption reduction has become a major issue related to the sustainable development of social economy such as national economic security, international market...

Problems solved by technology

At present, the traditional drying methods mainly include hot air convection heating, traditional infrared heating and other methods. Hot air convection heating has a great influence on the uniformity of heat in the furnace due to its large thermal inertia, long heating time, and furnace design structure, which is prone to temperature differences. , resulting in poor coating quality, prone to pinhole effect, foaming, its own equipment is huge, covers a large area, convection requires a large amount of circulating air flow, it is easy to cause dust in the furnace, causing secondary pollution of the paint surface, so using this Drying in this way not only has low work efficiency and poor working environment, but more importantly, it is dangerous
