A kind of sodium sulfite preparation roasting filter residue recycling and processing device

Abstract

The invention discloses a filter residue recycling and processing device for preparing roasting with sodium sulfite, and relates to the technical field of filter residue recycling. Including a filter residue screening mechanism and a mixed purification mechanism, the filter residue screening mechanism includes a screening box, the inner wall of the screening box is rotatably connected with two crushing wheels, the inner wall of the screening box is fixedly installed with a screening device, and the bottom of the screening device is installed. The end is fixedly installed with a discharge pipe and a recovery pipe. By setting up a filter residue screening mechanism, the filter residue is crushed by a crushing wheel, and then the specifications of the crushed filter residue are screened with the screening device, so that the filter residue that meets the specifications is entered into the mixing and purification mechanism for subsequent processing, and the filter residue that does not meet the specifications is dropped through the recovery pipe. Put it into the inside of the recycling box and wait for it to be crushed again, so that the specifications of the filter residues can be unified, thus avoiding the existence of large pieces of waste residue, solving the problem of poor recovery effect of large pieces of waste residue, and making the waste residue recovery more thorough.

Description

technical field [0001] The invention relates to the technical field of filter residue recovery, in particular to a filter residue recovery and processing device for preparing roasting with sodium sulfite. Background technique [0002] Sodium sulfite is an inorganic substance, chemical formula Na2SO3, common sulfite, white, monoclinic crystal or powder. It is irritating to eyes, skin and mucous membranes and can pollute water sources. Decomposed by high heat to produce toxic sulfide fumes. In industry, it is mainly used to make cellulose sulfite, sodium thiosulfate, organic chemicals, bleached fabrics, etc. It is also used as a reducing agent, preservative, and dechlorination agent. [0003] Sodium sulfite filter residue is a kind of industrial waste residue, and industrial waste residue refers to the toxic, flammable, corrosive, infectious disease, chemically reactive and other harmful solid waste discharged in industrial production. The long-term storage of solid waste o...

Problems solved by technology

[0004] In the treatment of waste residue, it is easy to cause large pieces of waste residue to be treated poorly due to the different sizes of waste residue, and it will also cause land pollution after discharge.
