Problems solved by technology

In the previous annealing kilns, the thermocouples in the middle and side areas were all associated with the damper, and the sensitivity of the damper was very high, but because its opening was fixed, the change of its temperature would not be very fast; at the same time, in the automatic When adjusting, the air valve will keep opening and closing in a certain range, which will also cause the temperature to fluctuate up and down in a certain range and easily cause damage to the air valve

Abstract

The invention discloses a full-automatic temperature control system of a glass production line annealing kiln, which comprises an intermediate thermocouple, an air supply module, a main control module and an air valve, the intermediate thermocouple, the air supply module and the air valve are respectively and electrically connected with the main control module, the intermediate thermocouple is arranged on an annealing kiln plate, the air supply module is arranged in the middle of the annealing kiln plate, and the air valve is arranged on an air pipe on the annealing kiln plate. According to the invention, brand-new control association is adopted, a full-automatic control system is used, production personnel only need to input desired temperature, the system can automatically control a fan and an air valve, and the actual temperature on site and a temperature difference cooling curve among all areas can reach an ideal state, so that glass has different physical properties more quickly, furthermore, the yield and the yield of the ultra-thin glass are improved, the cost of large-scale production of the ultra-thin glass is reduced, and preparation is made for production of various novel glass such as photovoltaic glass.

Description

technical field [0001] The invention relates to the technical field of glass technology, in particular to a fully automatic temperature control system for an annealing kiln of a glass production line. Background technique [0002] Glass production mainly consists of four sections: melting, tin bath, annealing furnace and cold end. The melting section is the first section of glass production. Its function is to melt various raw materials to form molten glass that meets the forming conditions; then there is the tin bath section. Its function is to slowly pull the viscous molten glass that has accumulated together. Open, and at the same time make it solidify to have the embryonic form of the glass; the next step is the annealing kiln, its function is to gradually cool down the embryonic glass, and the glass will produce different physical properties according to the temperature difference cooling curve between each zone; The last section that passes through is the cold end, wh...
