Waste oil discharging device for cutting fluid

Abstract

The invention discloses a waste oil discharging device for cutting fluid. The waste oil discharging device comprises a waste oil collection groove and a collection groove buoyancy uniform generation structure, wherein the waste oil collection groove comprises a groove body, a waste oil discharging opening, a waste oil collection structure and a counterweight mounting structure; the groove body comprises a groove bottom wall and a groove peripheral wall; the gravity center of the groove body is located on the vertical line passing through the bottom central point of the waste oil collection groove; the waste oil collection groove is formed in the groove body; the counterweight mounting structure is arranged at the central position of a groove bottom wall; the counterweight mounting structure is arranged along the peripheral direction of the top of the groove peripheral wall and is composed of a plurality of oil feeding openings which are annularly arranged; a liquid stopping wall is arranged between each two oil feeding openings; lower edges of the oil feeding openings are located on the same horizontal height; the collection groove buoyancy uniform generation structure comprises aplurality of floating balls with the same specification; the plurality of floating balls are fixed and annularly arranged at the periphery of the groove body; the plurality of floating balls are arrayed in the peripheral direction at equal distance, and uniform buoyancy on the groove body is generated. The waste oil discharging device for the cutting fluid has the characteristics of high waste oilremoving efficiency, stable and reliable work, capability of continuously working and the like.

Description

technical field [0001] The invention relates to the technical field of cutting fluid purification. Background technique [0002] During the processing of the workpiece by the machine tool, wear and high temperature will be generated due to high-speed friction between the tool and the workpiece. In order to reduce friction and reduce the high temperature generated by friction, when processing the workpiece, it is necessary to continuously spray the contact parts of the tool and the workpiece Cutting fluid, cutting fluid is recycled through the cutting fluid circulation system. Due to leakage and other reasons, it is inevitable that some machine tool lubricating oil and hydraulic oil will be mixed into the cutting fluid circulation system. As the cutting fluid circulation time continues to increase, The content of waste oil (machine lubricating oil and hydraulic oil) in the cutting fluid will increase, which will reduce the use function of the cutting fluid, weaken the lubrica...

[0002] During the processing of the workpiece by the machine tool, wear and high temperature will be generated due to high-speed friction between the tool and the workpiece. In order to reduce friction and reduce the high temperature generated by friction, when processing the workpiece, it is necessary to continuously spray the contact parts of the tool and the workpiece Cutting fluid, cutting fluid is recycled through the cutting fluid circulation system. Due to leakage and other reasons, it is inevitable that some machine tool lubricating oil and hydraulic oil will be mixed into the cutting fluid circulation system. As the cutting fluid circulation time continues to increase, The content of waste oil (machine lubricating oil and hydraulic oil) in the cutting fluid will increase, which will reduce the use function of the cutting fluid, weaken the lubrication effect, and will cause mechanical abrasion and wear, so that the precision of the processed workpiece cannot reach To meet the design requirements, at the same time, the high temperature generated by the friction between the tool and the workpiece will increase the temperature of the cutting fluid, thereby breeding anaerobic bacteria, causing the cutting fluid to deteriorate and smell, polluting the surrounding environment and affecting the health of workers
