A water-cooled tin bath tank bottom cooling system and its installation and use method

Abstract

The invention discloses a cooling system for the bottom of a water-cooled tin bath and an installation and use method thereof, wherein the cooling system for the bottom of a water-cooled tin bath includes a water inlet pipe (1), a return pipe (8) and a plurality of pipes connected between the water inlet pipe (1) and The cooling water pipe (4) between the return water pipes (8), the cooling water pipe (4) is located under the bottom plate of the tin bath (5), and is set close to the bottom plate (5) of the tin bath, the cooling water pipe (4) and the water inlet pipe (1) Connected through the water inlet control device (2). The invention uses water cooling instead of air cooling to cool the steel plate at the bottom of the tank, which can effectively control the temperature of the bottom plate and ensure the lateral temperature difference of the bottom plate. While achieving the same cooling effect, it has the advantages of low investment cost, simple operation, convenient management, energy saving and consumption reduction, etc. advantage.

Description

technical field [0001] The invention relates to a tin bath cooling system, in particular to a water-cooled tin bath bottom cooling system and an installation and use method thereof. Background technique [0002] Float glass production is a continuous process. Firstly, all kinds of uniformly mixed raw materials need to be sent to the glass melting furnace. After high-temperature chemical reaction, molten glass liquid is formed, which enters the tin bath, and is formed into flat glass by the edge pulling machine. After entering the annealing kiln, the temperature is gradually lowered and cooled to obtain the finished flat glass. [0003] As one of the three thermal equipments in float glass manufacturing, tin bath is the core equipment for glass forming. In float glass, how to protect the safe operation of tin bath is very important. Since the bottom brick of the tin tank is fixed by two or more stainless steel bolts welded to the bottom plate of the tank, however, the temper...

AI Technical Summary

Problems solved by technology

The cooling air system includes fan equipment, air duct system, nozzle system and control system. There must be two sets of fan equipment, one for use and one for backup, and double-circuit cables will be laid, which increases investment; The system requires stability and reliability, which increases the related operation management and maintenance costs. At the same time, the air duct system will also require a large amount of materials and a large amount of construction work.

[0005] In addition, there are also water-cooled methods, but generally the bottom of the tin bath is sprayed through water pipes. This method not only causes a lot of waste of water resources, but also is not easy to control, resulting in uneven cooling. The sprayed water column is also harmful. The bottom of the tin bath produces force, which affects the work of the tin bath and its own quality
