Problems solved by technology

This is very harmful to the environment
[0006] In addition, in the field of degreasing agents, solvent degreasing was used in large quantities before the middle of the last century. Later, because solvents are volatile, they pollute the workshop and have a great impact on the health of workers, and the degreasing products contain a lot of oil. So far, due to technical limitations, the solvent degreasing method is basically not used in the market

Embodiment 1

[0048] The present invention "a zero-discharge metal environmental protection cycle degreasing method and device that can recycle waste oil" provides a metal degreasing agent, and the components of the solvent 13 include: butane 45%, cyclohexane 15%, acetone 15%, butanone 25%; first add a certain height of water (sealing liquid) into the tank body 1, and then add the above-mentioned solvent 13 to the degreasing working area 16 of the device of the present invention. The workpiece 6 is a small mold, which is put into the workpiece pallet 2 of the device of the present invention, and is automatically degreased and regenerated by the device. After degreasing, hang it down for use.

Embodiment 2

[0050] The present invention "a zero-emission metal environmental protection cycle degreasing method and device that can recycle waste oil" provides a metal degreasing agent, the composition of the solvent 13 includes: gasoline 80%, kerosene 20%; first go to the tank 1, add a certain height of saline solution (sealing liquid), and then add the above-mentioned solvent 13 to the degreasing working area 16 of the device of the present invention. The workpiece 6 is an oiled screw, which is put into the workpiece pallet 2 of the device of the present invention, and is automatically degreased and regenerated by the device. After degreasing, hang it down for use.

Embodiment 3

[0052] The present invention "a zero-discharge metal environmental protection cycle degreasing method and device that can recycle waste oil" provides a metal degreasing agent. The composition of the solvent 13 includes: 100% solvent oil; A certain height of water (sealing fluid), and then the above-mentioned degreasing agent is added to the degreasing work area 16 of the device of the present invention. The tool is a hardware piece to be electroplated, which is placed on the workpiece tray 2 of the device of the present invention, and the device automatically degreases and regenerates. After degreasing, hang it down for use.

[0053] The invention can quickly remove grease and wax on the metal surface, whether it is vegetable oil, mineral oil or sintered oil formed at high temperature; whether it is grease or wax, whether it is light oil stain or heavy oil stain formed by long-term use (such as the inner liner of a liquefied petroleum tank) , can quickly remove them. The rol...

Abstract

The invention relates to the field of metal oil removal method and oil removal, in particular relates to a zero-emission metal environment-friendly circulating oil removal method and device capable ofrecycling waste oil and solves the key technical problems of environment pollution and worker health hazards caused by volatilization easiness of a solvent oil removal agent in a traditional oil removal method. Due to the adoption of a structure of the zero-emission metal environment-friendly circulating oil removal device, a solvent and a workpiece are sealed in an oil removal working region anda sealing liquid when equipment is in a working state, and thus, the phenomenon that the solvent is evaporated to pollute the environment is avoided, and the cleaned workpiece cannot be secondarily polluted. In addition, the two steps including oil removal and regeneration are circularly operated in the whole system, waste oil on the workpiece is continuously eluted along with the continuous oilremoval of the workpiece, while the solvent oil removal agent continuously works and is continuously regenerated and recycled in the whole system and can be repeatedly and permanently recycled if being fed once. In the whole oil removal process, no wastewater, waste oil and waste solvents are discharged, subsequent environment protection investment is not needed, and no environment protection worries exist, so that the cost is very low.

Description

technical field [0001] The invention relates to a metal degreasing method and the field of degreasing, in particular to a zero-discharge metal environmental protection cycle degreasing method and device that can recycle waste oil. Background technique [0002] Many oil materials are often used in the process of metal production and processing, such as: forming, cutting, grinding, etc. in the manufacturing process of metal products. Lubricating oil, cutting oil, etc. are used in many processing methods. During the stay of the workpiece, it is often immersed in oil (anti-rust oil) to isolate the workpiece from contact with oxygen and water vapor in the air, so as to achieve the purpose of corrosion protection. In order to ensure the quality of the next process (such as: passivation, oxidation, phosphating, electroplating, etc.), there must be a cleaning and degreasing process. [0003] Various metal degreasers that are often used at present mainly include strong acids, strong...
