Abstract

The invention discloses a reciprocating-turning-scraping heating negative pressure separator and solves the problems of low chlorine leaching residue desulfurization and solid dehydration efficiency,long technical process, complex structure of equipment and high cost. The reciprocating-turning-scraping heating negative pressure separator comprises a separation tank, a feeding device, a heating device, a reciprocating turning and scraping device, a condenser and a PLC (programmable logic controller) electric control box, the separation tank comprises a heating tank, a residue collecting tank and a tank cover, the reciprocating turning and scraping device is positioned in the heating tank and comprises a rotating shaft, a driving motor, an outward distributing disc, a scraper guide rod, anoutward scraper, an inward distributing disc and an inward scraper, the condenser and the separation tank are communicated through a gas collection pipe, one end of the gas collection pipe enters space above the heating tank while the other end of the same is connected with an inlet end of the condenser, and a negative pressure fan is arranged on the gas collection pipe; the PLC electric control box is functionally connected with the feeding device, the heating device, the negative pressure fan, the driving motor and the condenser. The separator is simple in structure, convenient to operate, capable of efficiently realizing desulfurization and dehydration and lowering production cost and stable in working.

Description

technical field [0001] The invention belongs to the technical field of heating negative pressure separation devices, and in particular relates to a reciprocating scraping type heating negative pressure separator. Background technique [0002] Chlorine leaching residue contains a relatively high amount of elemental sulfur (65%-70%), and also contains a certain amount of precious metals. Chlorine leaching slag is piled up for a long time, and the valuable metals in the material cannot be realized, resulting in the loss of valuable metals and polluting the environment. Due to the uniqueness of the chlorine leaching slag material, it is difficult to remove the sulfur element therein by using the existing hot filtration molten sulfur process. At present, the treatment of chlorine leaching slag usually adopts incineration process, the flue gas is used to make acid, and then the valuable metals are recycled. The process is long and the cost is high. For solid dehydration, the deh...
