Melting furnace cover opening smoke exhaust device

Abstract

The invention relates to the technical field of smelting furnace equipment, and discloses an uncovering smoke discharging device for a smelting furnace. The uncovering smoke discharging device for the smelting furnace comprises the smelting furnace, a chimney and a smoke discharging mechanism. A cover body is arranged at the top of the chimney. The smoke discharging mechanism comprises an elastic rod, a wind wheel, a rotary gear, a movable frame and a lever. The upper end of the elastic rod is fixedly connected with the cover body. Pushing blocks are arranged at the lower end and the upper end of the elastic rod correspondingly. The elastic rod is provided with external threads. The wind wheel comprises a circular ring. A disc provided with a through groove is arranged in the circle center of the circular ring, and the disc and the circular ring are connected through a plurality of fan blades which are arranged in the circumferential direction. The elastic rod is sleeved with the wind wheel. First teeth are arranged on half of the circumference of the rotary gear, and the rotary gear is arranged in a hollowed portion of the movable frame. The upper end and the lower end of the movable frame are connected with the pushing blocks on the elastic rod correspondingly. A plurality of second teeth are arranged on the inner walls of the two sides of the movable frame. The two ends of the lever are connected with the cover body and a turnplate correspondingly. The turnplate is connected with the rotary gear. By adoption of the uncovering smoke discharging device for the smelting furnace, rapid smoke discharging of the smelting furnace can be achieved.

Description

technical field [0001] The invention relates to the technical field of melting furnace equipment, in particular to a melting furnace cover opening smoke exhaust device. Background technique [0002] During the production of glass bottles, quartz sand, limestone, soda ash and other raw materials need to be uniformly mixed in proportion, then passed into the melting furnace, melted into a fluid under high temperature conditions, then blown into a mold, and finally annealed and cooled. When the glass raw material is melted at high temperature in the melting furnace, some substances in the raw material will volatilize, and a large amount of waste smoke will be generated. If the generated waste smoke is not discharged from the melting furnace in time, it will pollute the molten glass, resulting in The color of the glass crystal is dull and not crystal clear. In order to make the glass more transparent, it is necessary to take certain measures to deal with the waste smoke generate...

AI Technical Summary

Problems solved by technology

[0003] The traditional smoke exhaust treatment method is usually to install a chimney above the melting furnace, and open the chimney to naturally discharge the waste smoke generated in the melting furnace. This method can discharge a certain degree of waste smoke, but due to the slow rising speed of the waste smoke, And during the smoke exhaust process, the chimney is always open, which will easily lead to a large loss of heat in the melting furnace, which is not only not conducive to the melting of glass, but also causes innocent loss of energy. Therefore, a device that can speed up the smoke exhaust is needed
