AI Technical Summary

Technical Problem

Existing cutting fluid recovery technology is difficult to effectively remove particulate debris with a particle size of less than 50μm. Traditional methods have high energy consumption and equipment is prone to clogging, resulting in low recovery efficiency and environmental pollution.

Method used

The method of dynamic viscosity control, gradient centrifugal separation, interface adsorption fine treatment and closed-loop parameter optimization is adopted. A vortex structure is formed through a porous distributor. Combined with a three-stage centrifugal and layered variable porosity adsorption tower, the gas flow rate, centrifugal parameters and adsorption material regeneration are dynamically adjusted to achieve efficient separation of metal debris and oil.

Benefits of technology

It improves the recovery rate and purity of cutting fluid, reduces energy consumption and equipment maintenance frequency, and realizes the sustainability and economy of green manufacturing.

Abstract

The invention relates to the technical field of green manufacturing, in particular to a manufactured cutting fluid recovery treatment method based on an oil-scrap separation system, which comprises the following steps: step 1, dynamic viscosity regulation and control pretreatment; 2, gradient centrifugal separation, wherein the pretreated mixed liquid is subjected to three-stage centrifugal separation; 3, interface adsorption fine treatment is conducted, specifically, the oil liquid obtained after centrifugal separation flows through a layered variable-porosity adsorption tower, and regeneration of an adsorption material is triggered according to the pressure drop change; and step 4, optimizing closed-loop parameters, and dynamically correcting the control parameter thresholds in the steps 1-3 by collecting and processing the associated data of the process parameters and the final oil metal residual quantity. According to the method, through precise matching and dynamic adjustment of multiple steps, the separation effect can be improved to the maximum extent in the green manufacturing and cutting fluid recycling process, waste emission and resource waste are reduced, and the purposes of energy conservation and emission reduction are achieved.
