Antimony smelting reverberatory furnace batching device

Abstract

The invention discloses a proportioning device for an antimony smelting reverberatory furnace. The proportioning device comprises an antimony oxygen bin (1), a vibrator (9), a valve (2), a feed hopper (12), a reverberatory furnace material inlet (13) and the reverberatory furnace (8), wherein a measuring hopper (3) is arranged between the antimony oxygen bin (1) and the feed hopper; two spiral stirrers (5, 6) are arranged below the measuring hopper. The proportioning device for the antimony smelting reverberatory furnace, produced by adopting the method, has the advantages that the proportioning measurement is accurate and the stirring is uniform.

Description

technical field [0001] The invention relates to a batching device for a reverberatory furnace for antimony smelting. Background technique [0002] The main process of the reverberatory furnace for antimony smelting is to reduce the molten antimony oxide powder and refine and remove impurities, remove silicon, arsenic, lead and other impurities in the antimony oxide powder, and produce qualified refined antimony products. In the feeding process, because the antimony oxygen powder is directly put into the reverberatory furnace from the antimony oxygen bin, and the mixed reduced coal and soda ash are not stirred, a series of problems arise: first, the antimony oxygen powder in the reverberatory furnace is not in contact with the flux. Evenly, the part where the antimony oxide powder has a lot of contact with the reduced coal will agglomerate after reduction, the part with less contact with the reduced coal will melt slowly, the part where the antimony oxygen powder has more con...

Problems solved by technology

In the feeding process, because the antimony oxygen powder is directly put into the reverberatory furnace from the antimony oxygen bin, and the mixed reduced coal and soda ash are not stirred, a series of problems arise: first, the antimony oxygen powder in the reverberatory furnace is not in contact with the flux. Evenly, the part where the antimony oxide powder has a lot of contact with the reduced coal will agglomerate after reduction, the part with less contact with the reduced coal will melt slowly, the part where the antimony oxygen powder has more contact with soda ash will melt faster, and the part with less contact with soda ash will melt slowly The second is that when adding antimony oxygen powder, due to the high temperature in the reverberatory furnace, the material is directly fed into the furnace from the antimony oxygen bin, which will cause a large amount of antimony oxygen powder to be discharged instantly, and the antimony oxygen powder will be filled out of the reverberatory furnace feed port. , resulting in the loss of antimony oxide powder running outward; the third is that when feeding, the antimony oxide powder is instantly fed into contact with the high-temperature molten liquid in the reverberatory furnace, causing the antimony oxide powder to fly, resulting in the loss of antimony oxide powder running away; the fourth is the antimony oxide powder The antimony oxygen powder is directly put into the reverberatory furnace from the antimony oxygen bin, and the antimony oxygen powder into the furnace is not measured, so the accuracy of the production statistical data cannot be guaranteed
