A tin bath bottom brick fixing structure and locking tool

Abstract

The invention discloses a molten tin bath bottom brick fixing structure and a locking tool. The molten tin bath bottom brick fixing structure comprises a molten tin bath bottom brick, a bolt welded on a molten tin bath bottom plate, a nut arranged on the bolt, and a fastening pin plate; a bolt penetrating hole and a pin plate slot are arranged on the molten tin bath bottom brick; the bolt penetrating hole and the pin plate slot are penetrated in a crossed manner; the molten tin bath bottom brick is arranged on the bolt through the bolt penetrating hole; the fastening pin plate is equipped with a screw opening and the bolt at the pin plate slot of the molten tin bath bottom brick through the screw opening is sleeved with the fastening pin plate; the locking tool comprises a locking piece, a rod used for driving the locking piece and a hammer, wherein the inner wall structure of the locking piece is matched with the outer structure of the nut; and a locking bayonet is arranged on the outer wall of the locking piece. According to the invention, the bolt penetrating hole and the pin plate slot arranged on the molten tin bath bottom brick are extremely easy to machine; and moreover, the structure does not need to be sealed by mud, is convenient to install, and overcomes influences of the existing structure on production quality.

Description

technical field [0001] The invention relates to a tin bath bottom brick fixing structure and a locking tool, belonging to the technical field of glass production equipment. Background technique [0002] The tin bath is a molding equipment for the float glass production process. It has an iron shell and a lining of refractory bricks, which are used to hold high-temperature tin liquid. The tin bath bottom brick is a refractory brick for the bottom of the tin bath. If the tin liquid floats, it must be fixed on the steel plate at the bottom of the tank with bolts. In order to prevent the liquid tin from seeping out, there should be no holes on the steel plate at the bottom of the tank, so the bolts are welded on the steel plate at the bottom of the tank. The bottom of the entire tin bath is a completely symmetrical structure, and most of the bottom bricks used are rectangular cross-section bricks. [0003] On the bottom brick of the tin bath, there are two bolt holes; on the us...

AI Technical Summary

Problems solved by technology

There are three main problems in installing tin bath bottom bricks in this way. First, even if the mud sealing material is dried, the water in it cannot be completely drained, and a slight release during production will affect the glass forming. Second, The installation itself is not very convenient, and the sealing hole of the round table with three variable diameters is difficult to process
