step five: if the reading difference of the pressure gauge (10) is large before and after pressure maintaining in the fourth step, a control switch valve (16) on a water inlet pipe (14) is opened to enable the internal water pressure to be sufficient, meanwhile, a ceramic heating plate (30) is heated, a backwater conveying pump (7) works after heating for a few minutes, a water source at the position closest to the ceramic heating plate (30) is pumped out through an inner backwater pipe (29) and an outer backwater pipe (8), and enters a first water supply pipe (4) and a second water supply pipe (5) through a water supply header pipe (6) and enters from the upper end inside an outer frame (1) again to enable the internal water temperature to rise rapidly;
step six: after reaching a certain temperature, keeping the temperature and the pressure for 20 minutes, opening a control switch valve (16) on a drain pipe (15) to drain water, and continuously heating a ceramic heating plate (30);
step seven: after heating for a period of time, the cylinders (25) on the left side and the right side of the conveying frame (2) work simultaneously, the closing doors (18) on the left side and the right side are opened, the left side continues to enter the hollow glass window (28), and the original hollow glass window (28) is ejected out;
step eight: the ceramic heating plate (30) is continuously heated in the conveying process to dry the moisture in the hollow glass window, unqualified products in the hollow glass window (28) in the original batch are not tight in air tightness, water is required to enter under the action of certain pressure, the moisture is gasified under the heating action, the hollow glass window (28) has a atomization tendency, the hollow glass window (28) is proved to be unqualified products, and the unqualified products are directly selected;
step nine: if the reading difference of the pressure gauge (10) before and after pressure maintaining is not large and the pressure intensity is basically unchanged in the fourth step, the air tightness of the hollow glass window (28) is good, the air cylinders (25) on the left side and the right side of the conveying frame (2) directly and simultaneously work, the closing doors (18) on the left side and the right side are opened, the left side continuously enters the hollow glass window (28), the original hollow glass window (28) is ejected out and enters the next detection procedure as an airtight qualified product.
