Energy-saving and efficient display glass drying equipment

Abstract

The invention discloses an energy-saving and efficient display glass drying equipment. The equipment comprises a drying box and a hot air circulation system, a glass inlet and a glass outlet which are matched with display glass are formed at the two sides of the drying box, and the hot air circulation system comprises an air supply assembly, an air return assembly, a fresh air compensation assembly and a condenser. By the adoption of the technical scheme, hot air can be recycled, the running time of a heater is shortened, energy is saved, the filter element replacement cost and the heater maintenance cost are reduced, positive pressure can be kept in a drying box, external dust is prevented from entering the drying box, and the clean environment is guaranteed. Moreover, by additionally arranging the condenser which does not need extra energy consumption, water vapor in circulating hot air can be efficiently converted into condensate water through a condensation assembly, the drying efficiency of the display glass is greatly improved, effective heat exchange can be conducted, introduced fresh air is preheated through a preheating assembly, and the utilization efficiency of energy is further improved.

Description

technical field [0001] The invention relates to the technical field of display screen processing equipment, in particular to energy-saving and high-efficiency display glass drying equipment. Background technique [0002] Display glass needs to be dried on its upper surface in a clean environment during production and processing. Existing display glass drying devices are mainly divided into hot air circulation type and non-circulation type. Whether it is a hot air circulation drying device or a non-circulating drying device, it is necessary to install a filter at the air inlet to filter the dust in the air during work, so as to achieve the purpose of cleaning. [0003] The existing non-circulating drying device needs to continuously introduce fresh air, so it needs to filter a large amount of dust, resulting in frequent replacement of filter elements. Moreover, after drying the display glass, the hot air with a large amount of water vapor is directly discharged outside, whi...

Problems solved by technology

[0003] The existing non-circulating drying device needs to continuously introduce fresh air, so it needs to filter a large amount of dust, resulting in frequent replacement of filter elements

Moreover, after drying the display glass, the hot air with a large amount of water vapor is directly discharged outside, which wastes a lot of heat energy. Not only does the power consumption remain high, but also the water vapor is easy to condense on other equipment, polluting the workshop environment, so it is necessary to install Special equipment collects exhaust gas, which further increases production costs

[0004] Although the hot air circulating drying device can overcome the above-mentioned shortcomings of the non-circulating drying device, the existing hot air circulating drying device has a large amount of water vapor in the circulating air due to its own design defects, resulting in a drying efficiency much lower than that of the non-circulating drying device. The non-circulating drying device still cannot meet the actual production needs well
