Float pool bottom electrode heating device

Abstract

The invention discloses a float pool bottom electrode heating device, which comprises a pool bottom brick for fixing an electrode, wherein steel structure plates in bilateral symmetry are arranged atthe lower end of the pool bottom brick, a stepped hole is formed in the middle of the pool bottom brick and used for containing the electrode and a large water jacket, the large water jacket is installed at the lower end of the electrode, a small water jacket is connected to the bottom end face of the electrode, a binding post is connected to the bottom end face of the small water jacket, a binding post insulator is arranged in the inner cavity of the binding post, a pointer is installed at the lower end of the binding post insulator through an upper nut, a pointer seat is arranged at the lower end of the pointer, a bottom supporting plate is erected at the lower ends of the two steel structure plates, the pointer penetrates through the middle of the bottom supporting plate, and a lower nut is arranged at the joint of the pointer and the bottom supporting plate. According to the invention, the height of the electrode higher than the upper surface of the bottom of the kiln pool is adjusted by adjusting the lifting of the electrode at the bottom of the kiln pool to heat the molten glass in the kiln, so that the batch is reasonably molten into the molten glass.

Description

technical field [0001] The invention relates to the technical field of float glass manufacture, in particular to a bottom electrode heating device of a float glass. Background technique [0002] The furnace is the key equipment for the production of float glass. The traditional glass furnace is mainly composed of a melting part, a clarifying part, a neck, a cooling part, a regenerator and a flue. Among them, the role of the melting part is to melt the batch material into glass liquid to reach the required temperature. Since the melting temperature of high-temperature refractory glass is very high, the temperature of the hot spot can reach above 1650°C, and the batch material is melted into qualified glass through the high temperature in the kiln. Generally, the kiln burns heavy oil or natural gas to raise the temperature of the kiln to above 1650°C, but this burning method greatly shortens the service life of the kiln. [0003] In order to solve the above problems, high-end...
