Distillation and blowdown apparatus in distillation machine

Abstract

The invention discloses a distillation and blowdown apparatus in a distillation machine. The distillation and blowdown apparatus comprises a rack provided with four distillation boxes, including two big distillation boxes and two small distillation boxes, wherein the two small distillation boxes correspond to the two big distillation boxes one by one respectively; a dirt cleaning solvent can be delivered into the two big distillation boxes through a delivery pipeline respectively for heating distillation; the dirt cleaning solvent in each big distillation box can be delivered to a corresponding small distillation box through a delivery pipeline respectively for heating distillation; and an automatic blowdown apparatus is mounted on each of the two small distillation box, and has a structure as follows: the box wall of one end of the small distillation box is provided with a steam nozzle, the box wall of the small distillation box at the other end opposite to the steam nozzle is provided with a dirt discharge port, and a pipeline communicated with the dirt discharge port is provided with a stop valve capable of closing the dirt discharge port. The distillation and blowdown apparatus in the distillation machine not only can improve the distillation efficiency but also can fully recover the cleaning solvent and quickly and conveniently remove dirt in the distillation boxes.

Description

technical field [0001] The invention relates to the field of washing equipment, in particular to a distillation and sewage discharge device in a distillation machine. Background technique [0002] Existing dry cleaning machines usually use washing solvents such as tetrachlorethylene to wash clothes. After repeated washing, the washing solvent in the dry cleaning machine will become dirty. If you continue to use dirty washing solvents to wash clothes, it will definitely make the clothes Washing is not clean, so dry cleaning machines are usually equipped with distillation machines to perform stain removal cleaning of dirty washing solvents. The structure of the existing distillation machine includes: a frame, a distillation device capable of heating and distilling the dirty cleaning solvent is arranged on the frame, usually the distillation device is a device on the frame that can heat and distill the dirty cleaning solvent Distillation box, the dirty washing solvent in the d...

AI Technical Summary

Problems solved by technology

[0003] The disadvantages of the above-mentioned distillation device are: (1) After the dirty cleaning solvent is distilled into a paste, the steam of the cleaning solvent will be greatly reduced. However, since the distillation device only has one distillation box, if the cleaning solvent is fully recovered, it must It is necessary for the distillation box to continue distilling the pasty dirty washing solvent until the washing solvent vapor cannot be distilled out, which will greatly waste time and reduce the distillation efficiency. If in order to improve the distillation efficiency, it is necessary to distill the pasty dirty washing solvent from Only then can new dirty washing solvent be put in for distillation, but the discharged pasty dirty washing solvent is easy to pollute the environment, and there is still washing solvent in the pasty dirty washing solvent, which will also cause waste of washing solvent; (2) The distillation box will leave dirt in the distillation box after distilling the dirty washing solvent. The dirt in the distillation box is usually manually cleaned by workers through the cleaning door set on the distillation box. Manual cleaning of dirt is slow and easy to affect Productivity
