Problems solved by technology

At present, the solid-liquid separation technology for wear debris generally adopts membrane filtration technology. There are many consumables in the process of use, such as filter paper, filter cloth, filter elements, etc. At the same time, the proportion of emulsion and cutting oil in the separated wear debris is still As high as more than 60%, the separation effect is not ideal, and the internal temperature of a large amount of accumulated abrasive debris is high, which is prone to spontaneous combustion and is relatively dangerous

Embodiment Construction

[0037] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0038] The technical scheme of concrete implementation of the present invention is:

[0039] The metal grinding dust processed by the present invention is the waste produced by various machine tools using grinding wheels as cutting tools to process metal materials. The grinding dust contains metal particles of the processed material, abrasive grains, binders used to bond abrasive grains, and a large amount of cooling liquid.

[0040] The morphology of metal particles in grinding debris mainly includes the following categories:

[0041] A. Curly strip-shaped metal shavings, with a width and thickness of about 20 microns and a length of 50-140 microns;

Abstract

The invention discloses a metal abrasive dust briquetting method. According to the method, briquetting treatment is conducted on metal abrasive dust through a metal abrasive dust briquetting treatment device provided with a hydraulic system and a storage bin. Through the method, abrasive dust can be briquetted, the size of the metal abrasive dust is greatly decreased, liquid in the abrasive dust can be effectively separated, and the liquid content of the abrasive dust is greatly decreased, and abrasive dust transport and retreatment are facilitated. In the main briquetting process of the method, the extrusion speed is gradually decreased along with increasing of the pressure of hydraulic oil, and the abrasive dust can be prevented from being injected.

Description

technical field [0001] The invention relates to a method for briquetting metal grinding dust. Background technique [0002] Today, with the increasingly developed industrialization, the precision requirements for machined parts are getting higher and higher. In order to obtain higher product precision, many workpieces are precision-machined by grinding or similar to grinding. During the processing, many wear debris. Abrasive debris contains metal components, sand grains, adhesives used to manufacture grinding wheels, and a large amount of emulsion or cutting oil. Abrasive debris not only causes great pollution to the environment, but also causes a great waste of resources. [0003] In order to reduce the pollution of grinding debris to the environment and improve the recycling rate of grinding debris, it is very important to effectively separate the solid components and liquid components in grinding debris. At present, the solid-liquid separation technology for wear debris...
