Processing apparatus of dry cleaner residue
Technical Field
The invention belongs to the field of washing machinery, and relates to a treatment device for dry-cleaning residues of a dry cleaner.
Background
The washing solvent of the existing dry cleaning machine mainly adopts tetrachloroethylene, and fluff, impurities and the like brought by clothes can form dry cleaning residues in the dry cleaning process, the solvent filtering process and the solvent regeneration process, such as distillation residues generated when the regeneration solvent is distilled, fluff filtered and adhered in a fluff filter and a button catcher, fluff adhered on a drying condenser and a drying heater fin and the like. Although the dry cleaning residues of the dry cleaning machine are few, because the tetrachloroethylene is a violent poison, the dry cleaning residues containing the tetrachloroethylene cannot be randomly located and discarded when being discharged out of the machine, otherwise the environment and soil can be polluted, for example, the tetrachloroethylene in the dry cleaning residues is directly diffused into the atmosphere, the ozone layer is damaged, or the generation of haze is induced, and the atmospheric pollution is caused.
In order to avoid the dry-cleaning residues of the dry-cleaning machine from being directly and conveniently found and lost, thereby causing environmental and soil pollution, the invention provides the device for processing the dry-cleaning residues of the dry-cleaning machine, which is attached to the main machine of the dry-cleaning machine, and can conveniently process the dry-cleaning residues of the dry-cleaning machine, thereby achieving the aim of environmental protection.
