Ultrasonic salt bath combined cleaning machine for mechanical parts for test

Abstract

The invention discloses an ultrasonic salt bath combined cleaning machine for mechanical parts for a test. The ultrasonic salt bath combined cleaning machine comprises an upper portion and a lower portion. The upper portion comprises a sealing cover. The lower portion comprises an inner cleaning tank and an outer cleaning tank, wherein a cooling water tank is further arranged between the inner cleaning tank and the outer cleaning tank. A water inlet channel which is communicated with the inner cleaning tank, the cooling water tank and the outside world in sequence is arranged at the bottom of the outer cleaning tank, a water outlet channel which is communicated with the cooling water tank and the outside world is arranged on the side of the outer cleaning tank, and a plurality of ultrasonic transducers are symmetrically arranged on the side of the outer cleaning tank. An inclined salt discharging outlet is formed in the bottom of the inner cleaning tank; a plurality of semi-heating type electric heating tubes are symmetrically installed at the bottom of the inner cleaning tank, and the working temperature of the ultrasonic salt bath combined cleaning machine can be increased to 300-350DEG C through the semi-heating type electric heating tubes; the semi-heating type electric heating tubes generate heat only through the bottoms of the semi-heating type electric heating tubes, and the heat is used for reducing corrosion caused by high-temperature molten salt on the semi-heating type electric heating tubes.

Description

technical field [0001] The invention relates to a cleaning machine, in particular to an ultrasonic salt bath composite cleaning machine for mechanical parts used in testing. Background technique [0002] From the design of the machinery industry to all aspects of modern industry, during the processing, assembly, and disassembly of industrial products, the dirt on the surface of parts seriously affects the normal production and assembly process, because cleaning is of great significance, and the quality of cleaning is restricted Improve the efficiency of product production, cost and even corporate profits. [0003] Under the action of complex service environment and external field load, the surface and subsurface of remanufactured objects often form nano-scale, micron-scale or even deeper adsorption layers, pollution layers, denatured layers, etc. The types of defects and their characteristics on the surface and subsurface of the remanufacturing object shall be cleaned and t...

Problems solved by technology

However, in the process of actual use, the heating tubes in these two patents are always in a heated state. The molten salt is easy to corrode the heating tubes at the air contact interface, accelerate the aging of the heating tubes, and form corroded holes on the surface of the heating tubes. The tube is not working properly, the heating tube is difficult to replace
