dry cleaning machine

technical field

The invention relates to the technical field of dry cleaning machines, in particular to a dry cleaning machine.

Background technique

Due to the low frequency of use of household dry cleaning machines, in order to reduce the cost of use, the dry cleaning solvent needs to be recycled after washing. During the regeneration and recovery process of dry cleaning solvent, due to the small size and slow separation speed of the oil-water separator of the existing household dry cleaning machine, the oil-water separator is not easy to be directly connected with the washing drum, and the dry cleaning solvent is first stored in the dry cleaning solvent after being discharged from the outer drum of the dry cleaning machine. In the buffer tank, the dry cleaning solvent buffer tank is connected with the oil-water separator through the pipeline, and the draining speed of the dry cleaning solvent buffer tank is adjusted to control the liquid inlet speed of the oil-water separation, so that the solvent separated from the oil-water separator is stored through the pipeline into the solvent storage tank. It can be seen that the existing dry cleaning machine has complex operation control, slow separation speed and poor separation effect when the dry cleaning solvent oil and water are separated, and the whole separation system has a large volume.
