Low-consumption thermal circulation type glass processing kiln furnace

Abstract

The invention discloses a low-consumption thermal circulation type glass processing kiln furnace. The low-consumption thermal circulation type glass processing kiln furnace comprises a furnace body, wherein a feeding channel and a fuel gas pipe are arranged at upper parts of two sides of the furnace body respectively; a water tank and a working pool, which are parallel to the furnace body, are arranged at the outer side of the furnace body; the water tank and the working pool are located at two sides of the furnace body; a water outlet pipe is arranged at the top of the water tank; and a second heat exchanger is arranged on the water outlet pipe. According to the kiln furnace disclosed by the invention, three heat exchangers are arranged and pipelines are reasonably set and configured, sothat a fuel gas pre-heating function is realized, a combustion speed is improved and the processing time can be shortened; meanwhile, almost current feeding channels adopt metal channels so that performance changes, which are possibly caused by the fact that metal stays at high temperature state for long time, can be effectively avoided by cooling the metal channels, and the service life of the feeding channels is prolonged; surplus heat can be reasonably applied through water circulation and the energy-saving effect is realized; and air in glass liquid can be exhausted through a negative-pressure effect after glass is melted, and the quality of the glass liquid is improved.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a low heat consumption cycle glass processing kiln. Background technique [0002] Glass melting furnace refers to thermal equipment used to melt glass batch materials in glass manufacturing. The powder prepared according to the glass composition and the added clinker (broken glass) are melted at high temperature in the kiln, clarified and formed into a glass liquid that meets the molding requirements. Glassmaking is 5,000 years old, and the method of making glass, fueled by firewood, by melting glass batches in clay pots has continued for a long time. [0003] Chinese Patent Publication No. CN208454792U discloses a thermal cycle energy-saving glass kiln, which adopts a support frame to facilitate people to put in raw materials and reduce heat loss during operation, which has achieved the purpose of energy saving, but in actual use , most of the feeding channels are des...

[0003] Chinese Patent Publication No. CN208454792U discloses a heat cycle energy-saving glass kiln, which adopts a support frame to facilitate people to put in raw materials and reduce heat loss during operation, which has achieved the purpose of energy saving, but in actual use , the feeding channels are mostly designed with metal materials. Under long-term high-temperature conditions, the properties of metals will also change, which will affect the service life, and metals are heat-conducting substances. Continuous heat dissipation will still lead to waste of heat, increasing processing costs and Affect processing efficiency
