Problems solved by technology

[0003] In the existing dry cleaning machine, the condenser is cooled by circulating water, the heater uses pressurized steam to work, and a separate distiller is used to distill the solvent used for washing, and the condenser and the oil-water separator are separated and separated to remove water. , used again, the process connection is more complicated, the equipment volume is also very large, the structure is complex, and there are many systems

Embodiment 1

[0038] Such as figure 1 As shown, a dry cleaning machine includes an air supply system, a solvent condensation recovery system, a solvent filtration recovery system and a washing drum.

[0039] Wherein, the washing tub includes an inner tub 1 and an outer tub 2, and several openings (not shown) for solvent passage are arranged on the tub wall of the inner tub 1, and the clothes to be washed are placed in the inner tub 1 and The solvents required for dry cleaning are mixed, the inner cylinder 1 is driven to rotate by the driving device, and the clothes are continuously tumbled in the inner cylinder 1 to complete the washing of the clothes. A liquid inlet 3 , a liquid discharge 4 , an air inlet 5 and an exhaust port 6 communicating with the inner space of the outer cylinder 2 are opened on the wall of the outer cylinder 2 . In order to ensure the smooth inlet and outlet of liquid and gas, the liquid inlet 3 is located at the upper part of the outer cylinder 2, the liquid outlet...

Embodiment 2

[0067] Such as figure 2 As shown, the difference from Example 1 is that a solvent purification and recovery system is also provided in the dry cleaning device, and the solvent is purified before or after filtration.

[0068] The solvent purification and recovery system includes a heating device 31 for heating and evaporating the solvent. The heating device 31 adopts an electric heater and is set in the space between the wall of the inner cylinder 1 and the wall of the outer cylinder 2, and is arranged on the outer cylinder 2 bottom position.

[0069] When the solvent needs to be purified, the solvent is put back into the outer cylinder 2 along the liquid inlet path before washing, the heating device 31 is activated, the solvent evaporates in the outer cylinder 2, the solenoid valve 21 is opened, and the solvent vapor passes through the exhaust Port 6 and electromagnetic valve 21 enter the G section of the condensation pipeline 19. After being condensed by the condenser 12, t...

Abstract

The invention relates to a household dry cleaning device, a dry cleaning method and a dry cleaning solvent recovery method. A used dry cleaning solvent sequentially passes through a plurality of stages of filtering units, which are connected in series, to be filtered stage by stage so as to reach the standard of cleaning clothes, thereby circularly recovering and recycling the solvent. According to the invention, purification and recovery processing of a distiller on the solvent in the prior art are omitted; and not only can the washing flow be simplified and the solvent is simple, rapid and convenient to recover, but also structures of the distiller and the like in the prior art are omitted, so that the complete machine has a simple structure, equipment volume is reduced and the popularization and application of the dry cleaning machine in families are facilitated.

Description

technical field [0001] The invention relates to a household dry-cleaning device, a dry-cleaning method and a dry-cleaning solvent recovery method for cleaning and drying clothes by using a solvent, and belongs to the technical field of dry-cleaning. Background technique [0002] Existing dry cleaning machines that use solvents to clean clothes include: solvent tanks, solvent pumps, washing drums, liquid storage tanks, fans, heaters, condensers, distillers, oil-water separators, vacuum pumps, and the like. The dry cleaning process is roughly as follows: the solvent in the solvent tank enters the washing drum through the pipeline through the pump, so as to realize the liquid washing of the solvent. . When drying, the fan works, the cold air is turned into hot air by the heater and enters the drum, and the hot air takes the solvent vapor away through the liquid discharge port and enters the air channel of the condenser. After the hot steam passes through the condenser, the sol...
