Lower transmission sealing box used for producing float glass and roller-changing method thereof

Abstract

The invention relates to a lower transmission sealing box used for producing float glass and a roller-changing method thereof. The low transmission sealing box is characterized in that a gear box (1) is connected with a annealing kiln roller-way transmission shaft (1a) and connected with a steering gear (5) in a ground pit through transmission shafts (2, 3), the steering gear (5) is coaxially connected with three steering gears (7) in a ground pit through a transmission shafts (6), a steering gear (7) is connected with a steering gear (14) through transmission shafts (9, 11), and a steering gear (14) is connected with a shaft head of a transition roller (15). The transition roller (15) and a support (13) thereof are made into an integrated unit, and the integrated unit is in cooperated connection with a track in the sealing box. The invention has advantages that a transmission system is arranged in a ground pit, thereby providing full operation space for replacing the transition roller; the transition roller is made into modularized integrated unit, and the integrated unit can be drawn out for on-line replacing, thereby shortening roller-changing time and saving production cost.

Description

Background technique [0001] The sealed box is one of the important equipment of the float glass production line. Its main function is to transfer the glass ribbon about 600℃ from the tin bath into the annealing furnace, and at the same time seal the tin bath outlet, and also remove the strip from the tin bath. The tin dross on the lower surface of the glass prevents harmful gases from the tin bath from entering the annealing furnace. Since the production of float glass, although there have been many improvements in the sealed box, some problems have not been completely solved because the transmission system is set on the ground. For example, it is extremely difficult to replace the transition roller online; the tin tank outlet is not well sealed; the tin sticks on the roller Difficult to remove; the equipment is stuck due to thermal deformation, etc. Extensive searches have been conducted for the above problems, and no effective solutions have been found yet. Summary of the inven...

Problems solved by technology

Since the production of float glass, although there have been many improvements in the sealing box, some problems have not been completely solved because the transmission system is installed on the ground, such as the extremely difficult online replacement of the transition roller; poor sealing of the tin tank outlet; tin sticking to the roller Difficult to remove; rollers stuck due to thermal deformation of the equipment, etc.

Extensive searches for the above problems have found no effective solutions
