The present invention discloses a sealing structure for a suspended cooling water bag of a tin bath, wherein a cooling water bag is plugged and installed on the side wall of the tin bath, and a sealing structure is formed between the side wall of the tin bath and the cooling water bag, and the sealing structure includes a side sealing frame, a side sealing plate, a sealing gasket and a side sealing door. The side sealing frame is installed at a plug-in position on the side wall of the tin bath, and two side sealing plates are symmetrically arranged and buckled on the cooling water bag. The sealing gasket is located between the side sealing plate and the cooling water bag. The two side sealing doors are respectively rotated and installed on the two inner sides of the side sealing frame by torsion springs, and the two side sealing doors form a double door on the side sealing frame that opens into the tin bath. The cooling water bag sealing structure no longer requires a large amount of high-temperature resistant sealing material, and the thermal insulation effect is better than the traditional thermal insulation cotton and mud material sealing method, while increasing the sealing speed and reducing the sealing workload. When the cooling water bag is inserted and when the cooling water bag is pulled out, the two side sealing doors can automatically complete the closing, thereby sealing the side sealing frame.

Description

Technical Field

[0001] The invention relates to the technical field of float glass production equipment, in particular to a tin bath suspended cooling water bag sealing structure. Background Art

[0002] During the float glass production process, the primary facility in the forming section is the tin bath, where the float medium is molten tin. Numerous cooling water bags are installed throughout the float glass bath to cool the glass. Adjusting the number of cooling water bags controls the bath outlet temperature. The cooling water bags play a crucial role, leveling the glass to maintain the forming temperature in the high-temperature range and controlling the bath outlet temperature in the low-temperature range.

[0003] Due to the daily production needs of molding, the cooling water bag cannot remain in the tin bath for a long time. The water bags in the high, medium and low temperature zones need to be cleaned, replaced and maintained frequently. After cleaning and maintenance, the cooling water bag is inserted into the tin bath, and the water bag mouth needs to be sealed. A large amount of aluminum silicate fiber felt or insulation cotton and a large amount of mud are required to seal the water bag around it. In particular, the low temperature zone water bag needs to be frequently pumped out, so the consumption of insulation cotton and mud is always relatively large. Moreover, if the seal is not tight or the operation time is too long, a large amount of air will enter the tin bath from the outside, affecting the quality of the glass. Summary of the Invention

[0004] The purpose of the present invention is to provide a sealing structure for a suspended cooling water bag of a tin bath, so as to solve the problem that a large amount of high-temperature resistant sealing materials and personnel time and energy are wasted when the cooling water bag of the tin bath is penetrated, and there may be problems such as improper sealing of the cooling water bag or excessively long operation time, which affects the quality of the glass.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A tin bath suspended cooling water bag sealing structure comprises a tin bath, a cooling water bag is plugged and installed on the side wall of the tin bath, a sealing structure is formed between the side wall of the tin bath and the cooling water bag, the sealing structure comprises an edge sealing frame, an edge sealing plate, a sealing gasket and an edge sealing door, the edge sealing frame is installed at the plug-in position on the side wall of the tin bath, two edge sealing plates are symmetrically arranged and buckled on the cooling water bag, the sealing gasket is located between the edge sealing plate and the cooling water bag, the two side sealing doors are rotatably installed on the two inner sides of the side sealing frame by torsion springs, and the two side sealing doors form double doors on the side sealing frame that open into the tin bath.

[0007] A further technical solution is: the sealing gasket is aluminum silicate fiber felt.

[0008] A further technical solution is: the side-sealed door is divided into a left-sealed door and a right-sealed door, a Z-shaped sealing gap is provided between the left-sealed door and the right-sealed door, and a plurality of soft sealing strips are provided inside the Z-shaped sealing gap.

[0009] A further technical solution is: a plurality of the soft sealing strips and a plurality of sealing grooves adapted to the soft sealing strips are alternately arranged on the two sealing surfaces of the Z-shaped sealing gap.

[0010] A further technical solution is that the door length of the left sealed door is greater than the door length of the right sealed door.

[0011] A further technical solution is that the soft sealing strip is a roll made of soft high-temperature heat-insulating material.

[0012] A further technical solution is: the edge sealing plate is divided into an upper plate and a lower plate, and two opposite surfaces of the upper plate and the lower plate are provided with grooves adapted to the cooling water bag.

[0013] A further technical solution is: the upper plate and the lower plate are locked by a snap-on bolt structure, columns are provided on the plate surfaces of the upper plate and the lower plate, and column grooves adapted to the columns are provided on the outer side of the edge sealing frame.

[0014] A further technical solution is that the internal structures of the edge sealing plate and the edge sealing door are consistent, and the plate cavity of the edge sealing plate is filled with refractory material.

[0015] A further technical solution is that at least one layer of thermal insulation cotton is provided between the edge sealing plate and the refractory material.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0017] The present invention proposes a sealing structure for a suspended cooling water bag in a tin bath, in which a side sealing frame is installed on the tin bath, and a side sealing plate is combined with the water bag. When the cooling water bag is inserted into the tin bath, the side sealing plate and the side sealing frame cooperate with each other to perform a sealing function, which means that a large amount of high-temperature resistant sealing material is no longer required around the water bag. The thermal insulation effect is better than that of traditional thermal insulation cotton and mud sealing methods, which reduces heat loss, improves the sealing speed, reduces the sealing workload, and has a cleaner and tidier appearance.

[0018] In addition, when the cooling water bag is inserted, the cooling water bag can automatically push open the side sealing door to open it to the inside of the tin bath. When the cooling water bag is pulled out, the two side sealing doors can automatically close to seal the side sealing frame. BRIEF DESCRIPTION OF THE DRAWINGS
