An automatic control system for glass production process

Abstract

The present invention discloses an automatic control system of a glass production flow. The automatic control system comprises a PLC control cabinet, a first frequency converter, a feeding machine, amelting furnace and a liquid level sensor which are used to control the liquid level of the melting furnace, a second frequency converter, a draught fan, a premixer, a first valve, a second valve, a lance, a material channel and a temperature sensor which are used to control the temperature of the material channel, a third frequency converter, a material cutting machine, a rotating speed sensor, aconveyor belt, a photoelectric switch, a weight sensor, a first solenoid valve, a pressing machine and a second solenoid valve which are used to control the molding of the glass. An AO module of thePLC control cabinet is connected with the first, second and third frequency converters, an AI module is connected with the liquid level sensor, the temperature sensor, the rotating speed sensor and the weight sensor, a switching value input module is connected with the photoelectric switch, and a switching value output module is connected with the first and second solenoid valves, so that the problems that the conventional flow efficiency is low, and the quality of the glass is not high, are solved.

Description

technical field [0001] The invention relates to the field of glass production, in particular to an automatic control system for a glass production process. Background technique [0002] The production process of glass products basically consists of batch preparation, melting, molding and heat treatment. [0003] Batch material preparation refers to dehumidifying and iron removal of various raw materials, crushing and weighing them according to the designed material list, and mixing the ingredients evenly in the mixer according to the ratio in the material list. The main raw materials of glass include quartz sand and limestone. , feldspar, soda ash, boric acid, etc., among which limestone, feldspar, soda ash and boric acid act as cosolvents at the same time. [0004] The melting of glass refers to the process of transforming batch materials into molten glass with uniform chemical composition, no bubbles and meeting the molding requirements after high temperature heating. It ...
