Antimony powder production system

Abstract

The invention discloses an antimony powder production system which comprises a smelting furnace (1), an upper water-cooling time delay unit (2) and an antimony powder transferring pipeline (3). The water-cooling time delay unit (2) is arranged on an antimony powder outlet of the smelting furnace (1), and the antimony powder transferring pipeline (3) is connected with the upper water-cooling time delay unit (2). The cross section of a powder outlet of the upper water-cooling time delay unit (2) is oval, and a condensate water layer (21) is arranged in the peripheral wall of the upper water-cooling time delay unit (2). The antimony powder transferring pipeline (3) is composed of multiple bent pipes, and a conical hopper (31) is arranged at the connecting position of the lower ends of every two bent pipes. Through arranging the upper water-cooling time delay unit of which the cross section is oval, antimony powder is discharged from the smelting furnace and passes through the upper water-cooling time delay unit, distances between the antimony powder in the center and water grooves in the peripheral wall of the upper water-cooling time delay unit are equal, the distances between the antimony powder which passes through the whole outlet and the water grooves in the peripheral wall of the upper water-cooling time delay unit are small in difference, and therefore cooling is more sufficient and evener when the antimony powder is discharged from the furnace.

Description

technical field [0001] The invention relates to the technical field of antimony powder production equipment, in particular to an antimony powder production system. [0002] Background technique [0003] In the antimony processing industry, antimony powder is usually extracted in a high temperature melting furnace. Existing smelting furnaces are built horizontally on the floor of the workshop, and a feeding port is provided on the side wall of the smelting furnace. Usually, the antimony raw material is fed into the smelting furnace by using a shovel with a long handle. In existing equipment, it is inconvenient to use a shovel to add raw materials to the melting furnace. One is that the holding rod of the shovel is too long, which is easy to cause bending, and the holding rod heats up and is hot, which brings danger to the operation; second, the shovel tends to become soft at high temperature, and iron impurities are mixed in during the addition of antimony raw materials.
