Degreasing machine with solvent recovery function

Abstract

A degreasing machine with a solvent recovery function belongs to the technical field of degreasing equipment for degreasing powder metallurgy injection molding blanks. The degreasing machine comprises a box, a refrigerating unit, a condensing coil and a solvent collecting box, a heating clamp cavity is formed on the lower portion of a box cavity of the box, a heating device is arranged in the heating clamp cavity, a liquid collecting channel is formed on the inner wall close to the middle of the box cavity in the height direction, and a liquid outlet hole is arranged at the bottom of the liquid collecting channel. The refrigerating unit is arranged on one side of the box. The condensing coil is laid on the inner peripheral wall of the box cavity and corresponds to the upper side of the liquid collecting channel, and a liquid inlet and a liquid outlet of the condensing coil are connected with the refrigerating unit. The solvent collecting box is arranged on one side of the box and is connected with the liquid outlet hole in a matched manner through a solvent collecting pipe. The degreasing machine has the advantages that heating effect is fine, degreasing speed is fast, the temperature of the box cavity in a heating state can be guaranteed so as to shorten the heating time of the heating device and increase solvent extraction speed, the degreasing machine is environment-friendly, and resources are saved.

Description

technical field [0001] The invention belongs to the technical field of degreasing equipment used for degreasing powder metallurgy injection molding blanks, and in particular relates to a degreasing machine with the function of recovering solvent. Background technique [0002] Metal injection molding technology (Metal Injection Molding, referred to as MIM) is a technology that integrates plastic molding technology, polymer chemistry, powder metallurgy technology, and metal materials. Products with complex shapes can be sintered to manufacture structural parts with high density, high precision and three-dimensional complex shapes. This technology was first invented in the last century (1973) by Parmatech Corporation of California, USA, and was widely used in Europe, America and Japan in the early 1980s. This technology has the advantages of fewer process steps, no cutting or a small amount of cutting and high economic benefits, and can overcome the traditional powder metallur...

AI Technical Summary

Problems solved by technology

Moreover, since the side degreasing and the collection of volatile gas are carried out simultaneously, the temperature of solvent degreasing will be reduced to a certain extent, the degreasing time will be prolonged, and the energy consumption of the degreasing heating device will be increased.
