Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a drying equipment for processing LCD glass substrates, which is mainly used for performing drying pretreatment on LCD glass substrates. Background Art

[0002] ‌LCD glass substrate‌ is a basic component of liquid crystal display devices. It is a thin glass sheet produced by the float process with an extremely flat surface. It is the core component of liquid crystal display panels and is crucial to the electronic information display industry.

[0003] In the process of preparing liquid crystal display devices, first of all, the corresponding LCD glass substrate needs to be cleaned and dried for pretreatment. The existing drying equipment for processing LCD glass substrates mainly includes a roller conveyor and a drying chamber arranged on the roller conveyor. The heated hot air is transported to the drying chamber through the air supply mechanism, so as to dry the LCD glass substrate transmitted through the drying chamber, and the hot air with moisture formed by drying is directly discharged. Such drying equipment for processing LCD glass substrates has the following defects in actual use: 1) When the hot air continues to enter the drying chamber, it is very easy to carry dust and other stains, so that the LCD glass substrate after cleaning is re-adhered to dust and other stains; 2) The thermal energy utilization rate is relatively low, because most of the LCD glass substrates after cleaning are removed by the wind knife for cleaning liquid, so the water content is extremely low, so 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, the purpose of the present invention is to design a drying device for LCD glass substrate processing that can effectively and significantly reduce the probability of dust entering the drying chamber and significantly improve the utilization rate of thermal energy without affecting the smoothness of hot air circulation.

[0009] The exhaust pipe is provided with an air guide convex edge whose inner aperture is smaller than that of the moisture absorption filter cartridge, and the inner end portion of the moisture absorption filter cartridge is closed and abuts against the air guide convex edge.

[0010] The air guide pipe is connected to the air exhaust pipe through connecting pipes that are closed at both ends.

[0011] The air outlet ends of the air outlet pipes are respectively provided with air distribution containers facing the roller conveyor, the air inlet ends of the air distribution containers are connected to the air outlet ends of the air outlet pipes, the air outlet ends of the air distribution containers are arranged in long strips and facing the roller conveyor, and the electric heaters are fixedly installed in the corresponding air distribution containers.

[0015] The first rigid support plate is arranged in an inverted V shape and is arranged on the outer side of the second rigid support plate, and the second rigid support plate is arranged in an inclined plate shape.

[0016] Advantages of the present invention: 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. In this way, during the operation of the blower, the cylindrical filter core can be synchronously driven to rotate, so that the cylindrical filter core has obvious centrifugal force, thereby ensuring that the air volume generated by the operation of the blower can be smoothly discharged through the cylindrical filter core, so that the filtered air volume is driven into the air outlet pipe through the air distribution pipe and the air distribution pipe, and is heated in the air outlet pipe and blown to the upper and lower sides of the LCD glass substrate transmitted through the roller conveyor, thereby effectively and significantly reducing the probability of dust entering the drying room without affecting the smoothness of hot air circulation.

Thus, the hot air blown to the upper and lower sides of the LCD glass substrate is timely exhausted, and after a small amount of moisture contained in the hot air is absorbed, the hot air with residual heat is blown to the LCD glass substrate about to enter the drying chamber through the wind knife, so as to pre-dry the LCD glass substrate about to enter the drying chamber, thereby effectively improving the drying effect of the LCD glass substrate, so as to effectively and significantly improve the utilization rate of heat energy without affecting the smoothness of the hot air circulation.

[0018] 3) The present invention uses a cover plate to detachably install the moisture-absorbing filter cartridge installed with moisture-absorbing desiccant material on the side of the exhaust pipe close to the feeding end of the drying chamber, so as to facilitate the replacement of the moisture-absorbing desiccant; and the exhaust pipe is provided with an air guide convex edge with an inner aperture smaller than that of the moisture-absorbing filter cartridge. After installation, the inner end of the moisture-absorbing filter cartridge is closed and abuts against the air guide convex edge. This ensures that all the hot air with moisture passes through the moisture-absorbing filter cartridge and contacts the moisture-absorbing desiccant before entering the wind knife for discharge, thereby effectively ensuring the practical effect of the present invention.

[0019] 4) The cylindrical filter element of the present invention comprises a cylindrical frame and a plurality of filter plates fixedly mounted on the cylindrical frame, and the cylindrical frame comprises a connecting flange that is docked with the connecting pipe, and a bottom end plate that is spaced apart from the connecting flange, and a plurality of groups of corresponding first rigid support plates and second rigid support plates are spaced apart and staggered between the connecting flange and the bottom end plate, and the filter plates are fixedly connected between two adjacent first rigid support plates and second rigid support plates, respectively. Thus, the filter plates are tilted at a certain angle, so that the cylindrical filter element has a larger filtering area during the rotation process, and the cylindrical filter element has a more sufficient centrifugal effect during the rotation process.

[0020] 5) The first rigid support plate of the present invention is arranged in an inverted V shape and arranged outside the second rigid support plate, while the second rigid support plate is arranged in an inclined plate shape. Therefore, during the rotation of the cylindrical filter element, the dust attached to the filter plate is effectively concentrated into the first rigid support plate arranged in an inverted V shape by centrifugal force, so as to ensure the filtering efficiency of the filter plate, thereby further ensuring the practical effect of the present invention.

[0035] The air guide pipe 701 is connected to the exhaust pipe 702 through connecting pipes 13 with closed ends.
