Device to optimize the washing in dry cleaning machine

Abstract

The device consists of two heat exchangers (11, 14) bathed in paraffin wax (13) and placed in thermal insulated tank (8) to store up the heat generated to the refrigerator (2) and to heat the sole solvent used for the washing and with the feed back control circuit to keep the solvent temperature within temperature values set out in a thermostat (31).

Description

Technical field [0001] The invention relates to a device, which can keep a solvent used in a dry cleaning machine at an optimum temperature, thereby achieving better oil removal ability. Background technique [0002] In dry cleaning machines, the temperature of the solvent plays an important role. In fact, at a certain temperature, the solvent's washing ability is weak, and when the temperature is higher than the limit temperature, the solvent's washing ability on the fiber fabric during the dry cleaning process is very strong. In a machine using a flammable solvent, if the temperature of the high-temperature solvent exceeds the combustion temperature of the solvent, it will be dangerous to the machine. It is known that in prior art systems, hot water such as from a refrigerator is used to heat the solvent of the dry cleaning machine. However, because these systems heat all the solvents in the machine, they create a good environment for the production and propagation of bacteri...

AI Technical Summary

Problems solved by technology

In fact, the temperature of the solvent in the morning will be lower than the median value, so the dry cleaning effect will be poor at the beginning or in the first few working cycles

Other disadvantages of the prior art systems are the fact that temperature variations of the solvent also change the hygroscopicity of the solvent, e.g. in filter cartridges, increasing the likelihood that the concentration of water in the solvent will become high, also creating washing problems and causing bacteria reproduce
