Problems solved by technology
During the smelting and feeding process, antimony oxide powder will generate dust; at the same time, during the ingot casting operation, it will cause losses due to the oxidation and volatilization of refined antimony
At present, in the same industry, some enterprises have installed dust collection devices in their smelting and feeding parts, but due to the poor dust collection effect, they have not been put into use in actual production, resulting in: On the one hand, antimony is added to the reverberatory furnace When the oxygen powder or antimony ingot is cast, the antimony oxide escapes and emits seriously, the amount of antimony metal is lost, the reverberatory furnace is straight, and the recovery rate is not high; on the other hand, the antimony oxide powder that escapes and emits into the air is harmful to the health of employees ; On the other hand, the antimony oxide powder running and escaping affects the staff's feeding, which is not conducive to the operation, and prolongs the smelting cycle of the reverberatory furnace for a single batch
There are also some enterprises that specially install a set of dust collection system in the ingot casting machine. Although the antimony oxide volatiles generated during the ingot casting of antimony ingots can be collected, the investment in equipment is increased.

Embodiment Construction
[0009] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0010] The reverberatory furnace dust collection system of the present embodiment is composed of a reverberatory furnace 1, an ingot casting machine 2, a dust collection cover 3, a dust collecting flue 4, a feeding hopper mouth 5, a feed bin 6, a reverberatory furnace flue 7 and a fire cabinet 8 and Dust collecting cloth bag 9 forms.
[0011] One side of the reverberatory furnace 1 is a fire cabinet 8, and the flue on the top of the fire cabinet 8, that is, the reverberatory furnace flue 7, communicates with the dust collection device of the reverberatory furnace 1 itself, that is, the reverberatory furnace baghouse. The lower part of the reverberatory furnace 1 is equipped with an ingot casting machine 2, and a dust collection cover 3 is installed between the antimony outlet of the reverberatory furnace 1 and the ingot casting machine 2, and the dust c...

The invention discloses a dust collecting system of a reverberatory furnace, which belongs to the technical field of smelting and comprises a reverberatory furnace 1, a casting machine 2, a duct collecting cover 3, a duct collecting flue 4, a charging hopper opening 5, a stock bin 6, a reverberatory furnace flue 7, a fire cabinet 8 and a duct collecting bag 9. The invention has the advantages of reducing escape and emission of antimony oxide in casting ingots by adding antimonyl powder or antimony, reducing the loss of antimony, improving the direct recovery rate and the recovery rate of the reverberatory furnace, reducing factors harming health of personnel during production and being convenient for the personnel to operate, shortening the smelting period, improving the production efficiency and reducing the investment intensity and the production cost and the like. Therefore, the invention is suitable for the reverberatory furnace for refining antimony and reverberatory furnaces for refining other metals.
Description
technical field [0001] The invention relates to the technical field of smelting, in particular to a reverberatory furnace dust collection system applied in antimony smelting. Background technique [0002] In the prior art, reverberatory furnaces are mostly used in the antimony smelting industry, and the subsequent ingot casting process is integrated to realize continuous operation. During the smelting and feeding process, antimony oxide powder will generate dust; at the same time, during the ingot casting operation, it will cause losses due to the oxidation and volatilization of refined antimony. At present, in the same industry, some enterprises have installed dust collection devices in their smelting and feeding parts, but due to the poor dust collection effect, they have not been put into use in actual production, resulting in: On the one hand, antimony is added to the reverberatory furnace When the oxygen powder or antimony ingot is cast, the antimony oxide escapes and ...
