Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and specifically refers to a drying device for processing LCD glass substrates, which is mainly used for pre-drying LCD glass substrates. Background Art

[0002] ‌An LCD glass substrate‌ is a basic component that makes up a liquid crystal display device and is a float-produced thin glass sheet with an extremely flat surface. It is the core component of a liquid crystal display panel and is crucial for the electronic information display industry.

[0003] During the preparation process of liquid crystal display devices, first, the corresponding LCD glass substrates need to be cleaned and pre-dried. Existing drying devices for processing LCD glass substrates mainly include a roller conveyor and a drying chamber provided on the roller conveyor. Hot air heated by a blowing mechanism is sent into the drying chamber to dry the LCD glass substrates passing through the drying chamber, and the hot air with moisture formed by drying is directly discharged. Such drying devices for processing LCD glass substrates have the following defects in actual use: 1) When hot air continuously enters the drying chamber, it is extremely easy to entrain dust and other stains, resulting in the reattachment of dust and other stains to the cleaned LCD glass substrates; 2) The thermal energy utilization rate is relatively low. Since most of the cleaned LCD glass substrates have had the cleaning liquid removed by an air knife, the moisture content is extremely low. Therefore, the moisture in the hot air formed by drying is relatively low as a whole, and directly discharging the hot air formed by drying will result in a relatively low thermal energy utilization rate.

[0004] Therefore, on the basis of not affecting the smooth flow of hot air, the research objective of the present invention is to design a drying device for processing LCD glass substrates that can effectively and significantly reduce the probability of dust entering the drying chamber and can significantly improve the utilization rate of thermal energy.

[0020] Advantages of the present invention:

[0021] 1) The blower of the air inlet mechanism of the present invention is connected to the corresponding air distribution pipe, one end of the air distribution pipe is closed, and the other end is detachably installed with an end cover plate, a connecting pipe is sealed and rotatably installed in the air distribution pipe, and a cylindrical filter core facing the end cover plate is fixedly connected to the connecting pipe, and then the air inlet end of the blower is connected to the side of the connecting pipe that is not connected to the cylindrical filter core; finally, the impeller of the blower and the connecting pipe are respectively connected to the output shaft end of the corresponding driving motor.

[0039] The present invention is further provided with an exhaust air mechanism 7, which includes two rows of air guide pipes 701 connected side by side in height to the side of the drying chamber 1 where the air inlet mechanism 3 is not provided.

Thereby ensuring that the hot air with moisture can enter the air knife 11 for discharge only after passing through the moisture absorption filter cartridge 801 and contacting with the desiccant 802 for moisture absorption, thus effectively ensuring the practical effect of the present invention.

[0050] The first rigid support plate 30413 is arranged in an inverted V shape and is arranged outside the second rigid support plate 30414. The second rigid support plate 30414 is arranged in an inclined panel shape. Thereby, when the cylindrical filter element 304 is rotating, it can effectively concentrate the dust attached to the filter plate 3042 into the first rigid support plate 30413 arranged in an inverted V shape under the action of centrifugal force, so as to ensure the filtering efficiency of the filter plate 3042, and further ensure the practical effect of the present invention.
