Problems solved by technology
The first type is to use a slag press as a slag removal system, and the other is to use a centrifuge as a slag removal system. Both of these two types need to use electricity for slag removal, and the amount of slag removed by the slag press and centrifuge is different each time. Many, it needs to remove slag several times in batches, the efficiency of slag removal is relatively low, and special personnel are required to be on duty to operate

The invention proposes a slag removal system which comprises a setting tank and a filtering sleeve, wherein the setting tank comprises a first chamber, a second chamber and a third chamber, the first chamber is located at the upper part of the setting tank, and the top end of the first chamber is provided with an opening; the second chamber is located at the lower part of the setting tank, and provided with a first outlet; the first chamber and the second chamber are mutually communicated through multiple through holes; the third chamber after passing through the second chamber is communicated with the first chamber, and provided with a second outlet; the filtering sleeve is fixedly adhered to the inner walls of the first chamber and the third chamber, and extends out of the second outlet; and the filtering sleeve extending out of the second outlet is provided with a third outlet which is fastened by using a rope or a belt. The slag removal system disclosed by the invention carries out slag removal without using electric power; and the slag removal system is high in slag removal efficiency, and plays a significant role in energy saving and efficiency increasing.
Description
technical field [0001] The invention relates to the technical field of industrial waste slag discharge, in particular to a slag removal system for removing aluminum fluoride sediment generated during surface pretreatment of aluminum profiles. Background technique [0002] "Acid Etching and Grinding" is an important surface pretreatment process for aluminum profiles. The principle is to immerse the aluminum material in the ammonium bifluoride solution, and use the ammonium bifluoride to corrode the aluminum alloy to obtain a uniform and fine sandy aluminum surface while achieving a matte effect. . A large amount of aluminum fluoride sediment will be produced during this treatment process. In order to maintain the stability of the process, such sediment must be removed in time. Conventional slag removal is to pump the slag-containing turbid bath liquid into the slag press for pressure filtration, and finally bag the dehydrated slag manually. Another type of slag removal is t...
