Interporosity flow double-distilled box structure in fur defatting machine

Abstract

The invention relates to an interporosity flow double-distilled box structure in a fur defatting machine. A distilled box of the fur defatting machine is changed from an originally single-box structure into a double-box structure; the bottom plane of a solvent cavity of the distilled box is changed into a polygonal heating bottom plane; the top surface of the solvent cavity of the distilled box isadditionally provided with a balanced air suction port connected with a pressure one-way valve; the lower box structure is additionally provided with a lower box auxiliary heater; a connecting flangeof a cleaning door of the distilled box is provided with a discharge port of interporosity flow, the upper box and the lower box can be communicated by a pipe so that the liquid flows between the twoboxes, and the interporosity flow or discharge pipe is added with a steam cleaning function and the function of using steam to clean the solvent cavity.

Description

Technical field [0001] The invention relates to a dry cleaning machine or a fur degreasing machine, in particular to a distillation box of a fur degreasing machine. Background technique [0002] Fur degreasing machine is a kind of degreasing and washing machine suitable for degreasing and washing the grease on the fur of sheep, dog, rabbit, mink, fox, weasel, goose and other animal skins, or washing semi-finished garments and finished garments made of the above fur Dry cleaning equipment, degreasing washing solvent is tetrachloroethylene (C 2 Cl 4 ). The difference between the fur degreasing machine and the general dry cleaning machine is that the rated loading capacity is large, generally the rated loading capacity is 30Kg or more to about 150Kg; the tetrachloroethylene solvent contains a large amount of animal fat and other stains after a degreasing washing, which is generally not suitable for direct For secondary use, it must be recycled after distillation, regeneration and r...

AI Technical Summary

Problems solved by technology

[0005] 1. The heating surface of the steam heating chamber and the solvent chamber is a plane structure, the heat transfer area is limited, and the distillation efficiency is slow

[0006] 2. When the high-temperature solvent in the solvent chamber has not been distilled, the injection of cold tetrachlorethylene solvent will cause a rapid cooling and cause the solvent chamber to form a negative pressure state, which will easily lead to frequent concave and convex deformations on the bottom of the solvent chamber, which will affect the cracking of corner welds, Leakage affects the service life of the distillation box

[0007] 3. After several times of continuous distillation, a layer of grease will be formed on the upper layer of the dirty tetrachlorethylene solvent. Single-sided heating cannot effectively break up the grease covering the upper layer, which seriously affects the distillation efficiency.

[0008] 4. The structure of a single distillation box. When the perchlorethylene solvent in the distillation box contains serious oil, it can only be cleaned after a long time of distillation and cooling. It needs to stop distillation for a long time, which cannot effectively meet the needs of continuous use of equipment
