Backflow-free maintenance-free throat of glass kiln

Abstract

The invention discloses a backflow-free maintenance-free throat of a glass kiln. The backflow-free maintenance-free throat comprises a glass kiln melting part, a glass kiln backflow-free maintenance-free throat and a glass kiln forming part which are connected in sequence, a metal lining is arranged in the glass kiln non-backflow and non-maintenance throat; and the backflow-free maintenance-free throat further comprises a first glass kiln non-backflow maintenance-free throat accessory, a second glass kiln non-backflow maintenance-free throat accessory, a third glass kiln non-backflow maintenance-free throat accessory and a glass kiln non-backflow maintenance-free throat anti-blocking system. The backflow-free maintenance-free throat has the following advantages: the section of the throat is reduced, the flow velocity of molten glass is greatly increased, the backflow of the molten glass is avoided, and the energy consumption is reduced. The backflow-free maintenance-free throat can reduce investment, save energy and reduce consumption, does not need maintenance in the whole kiln passing period, is worry-saving and labor-saving, and is suitable for all throat glass kilns. As the service life of the throat is greatly prolonged, the service life of the kiln can be prolonged, and the cycle productivity of the kiln is improved.

Description

Technical field [0001] The present invention relates to the field of glass manufacturing, and the kiln major, kiln flowing hole technology, specifically means that a glass kiln has no reflow without maintenance fluid cave. Background technique [0002] Glass products do not exist in daily life, and we often use various products made of glass. Such as flat glass, electronic glass, glass fiber, daily glass, medicinal glass. Because of its characteristics such as special physicochemical properties and energy saving, environmental protection, recyclable utilization, a wide range of applications worldwide. [0003] The glass kiln is a key apparatus for glass production. The fluid cave is the most critical part of the glass kiln, which is the throat of the glass furnace melting clear glass fluid to the work portion. [0004] The existing glass kiln flowing cave is made with advanced refractory materials. High temperature erosion, peeling, exactly affecting the quality, yield and produc...

AI Technical Summary

Problems solved by technology

Due to the high temperature erosion and spalling of refractory materials, the quality, output and production cycle of the product are seriously affected

Due to the limitation of the flow rate of the molten glass, the section of the flow hole cannot be designed to be too small, and due to high temperature erosion and peeling, the section of the flow hole gradually expands, and the flow rate of the glass liquid slows down, resulting in a large amount of backflow of the glass liquid and increased energy consumption.

In order to slow down the damage of the flow hole, it is necessary to equip high-power cooling equipment to increase investment, energy consumption and production costs
