Reflecting furnace for production of castables

Abstract

The invention relates to a reflecting furnace for production of castables, which is provided with a furnace body; the lower part of the furnace body is fixedly connected with a fluid collecting tank,and the upper part of the fluid collecting tank is provided with a slope face at the lower end of the furnace body, several fluid discharge pipelines are vertically arranged in the slope face along the length direction of the furnace body and connected with the fluid collecting tank after crossing through the bottom part of the furnace body; one side of the furnace body at one end of the slope with high altitude is provided with a nozzle, the front end of the nozzle at the upper end of the furnace body above the slope face is provided with a feeding opening, and the other side of the furnace body at the one end of the slope face with low altitude is provided with a slag discharge opening; the front end of the slag discharge opening above the furnace body is provided with a smoking hood, the smoking hood is connected with a purifying tank through a pipeline; the upper end of the purifying tank is provided with an air discharge opening. The reflecting furnace for production of castablesis simple in structure, and can rapidly fuse materials and separate the filter slag from the fusion fluid, effectively recycle heat of high-temperature smoke gas, protect environment, reduce production cost, improve the whole production efficiency, and increase economic benefit.

Description

technical field [0001] The invention relates to the technical field of castable production equipment, in particular to a reverberatory furnace for castable production. Background technique [0002] The reverberatory furnace is a traditional pyrometallurgy equipment. The structure is simple, the operation is convenient, and it is easy to control. It is widely used in the fields of smelting waste lead-acid batteries, lead scum, tin furnace slag, etc. The reverberatory furnace is a fixed hearth, the material is in a static state during smelting, the heat and mass transfer efficiency between materials is low, and the smelting cycle of materials is generally longer. The reverberatory furnace is mostly fed on the top of the furnace, and a material pile will be formed in the furnace. It is necessary to manually remove the material pile from the operation door. The labor intensity is relatively high. Moreover, after the material is added into the furnace body, the material accumula...

The reverberatory furnace is a fixed hearth, the material is in a static state during smelting, the heat and mass transfer efficiency between materials is low, and the smelting cycle of materials is generally longer

The reverberatory furnace is mostly fed on the top of the furnace, and a material pile will be formed in the furnace. It is necessary to manually remove the material pile from the operation door. The labor intensity is relatively high. Moreover, after the material is added into the furnace body, the material accumulation will not be fully contacted and heated, resulting in melting. The time becomes longer; in the normal production process of the reverberatory furnace, high-temperature flue gas is also generated, which is usually discharged directly, which not only pollutes the environment, but also wastes heat energy
