A safety protection mechanism for the discharge port of a vacuum furnace

Abstract

The invention discloses a safety protection mechanism for a discharge port of a vacuum furnace and relates to the field of accessory devices of vacuum furnaces. The safety protection mechanism comprises a first discharge pipe, a distribution basin and a collection basin, wherein one end of the first discharge pipe is arranged at the discharge port of the vacuum furnace; the other end of the firstdischarge pipe is connected with a second discharge pipe; a protective plate is arranged on the first discharge pipe; an end side of the second discharge pipe is connected with a third discharge pipe;the distribution basin is fixed on a worktable of the vacuum furnace; the collection basin is fixed on a worktable of the vacuum furnace. By means of arrangement of a combined pipeline comprising thefirst discharge pipe, the second discharge pipe and the third discharge pipe and cooperative arrangement of the distribution basin and the collection basin, melt is guided into the collection basin and conveyed to next process for use through a pressure pump, safety accidents caused by overhigh temperature of the melt after metal smelting are reduced, the security coefficient is increased, the melt is guided and collected conveniently, and automatic production is realized.

Description

technical field [0001] The invention belongs to the field of vacuum furnace accessory equipment, in particular to a safety protection mechanism for a discharge port of a vacuum furnace. Background technique [0002] In recent years, with the development of science and technology, the demand for tin has continued to increase, resulting in a decrease in tin ore resources that are easy to mine and select, and more and more fine-grained tin slime. A large amount of these slimes are accumulated in the tailings due to the limitation of recovery technology, which not only makes the recovery rate of tin in tin concentrate low, but also leads to an increase in the dosage of chemicals and an increase in production costs. At present, the tin resources in the world are limited, the grade of raw ore is decreasing year by year, and the ore properties are becoming more and more complex and difficult to separate, such as cassiterite crystal grain size becomes finer, the symbiosis relationsh...

Problems solved by technology

[0004] The purpose of the present invention is to provide a safety protection mechanism for the discharge port of a vacuum furnace, which is provided with a combined pipeline with a first discharge pipe, a second discharge pipe and a third discharge pipe, and is equipped with a diversion basin and a confluence basin , divert the melt to the confluence basin, and then transfer the melt to the next process through the pressure pump, which solves the problem that the existing metal smelting melt temperature is too high, which is easy to cause safety accidents, low safety factor and melt The problem of diversion and collection inconvenience
