Ultraviolet disinfection device for cutting fluid and method for determining disinfection efficiency of same

Abstract

The invention discloses an ultraviolet disinfection device for cutting fluid. The device comprises a metal long tube, a glass tube, an ultraviolet lamp tube, a disinfection tube liquid inlet, a disinfection tube liquid outlet and a disinfection tube base, wherein the outer diameter of the ultraviolet lamp tube is smaller than the inner diameter of the glass tube, and the outer diameter of the glass tube is smaller than the inner diameter of the metal long tube. The ultraviolet lamp tube is sleeved with the glass tube, the glass tube is sleeved with the metal long tube, a cutting fluid channel is formed between the metal long tube and the glass tube, and the disinfection tube liquid inlet and the disinfection tube liquid outlet separately communicate with the cutting fluid channel formed between the metal long tube and the glass tube. According to the ultraviolet disinfection device for the cutting fluid, an ultraviolet sterilization and disinfection technology is adopted, and the ultraviolet sterilization and disinfection principle lies in that molecular structures of DNA or RNA in cells of microbial organisms can be destroyed by utilizing ultraviolet rays with proper wavelengths, so that growth cells and regenerative cells are killed, and the sterilization and disinfection effects are achieved.

Description

technical field

[0001] The invention belongs to the technical field of cutting fluid treatment in the field of energy saving and environmental protection of mechanical processing in the environmental protection industry, and in particular relates to a cutting fluid ultraviolet disinfection device and a method for determining its disinfection efficiency. Background technique

[0002] At present, the pollution caused by cutting processing methods at home and abroad is still very large. Non-traditional dry machining methods such as dry cutting, jet cooling and liquid nitrogen cooling have appeared, but dry machining methods also have their shortcomings that are difficult to solve. Therefore, it is still relatively far away from wet machining that completely replaces water-based cutting fluids. High-performance green The development of environment-friendly water-based metal cutting fluid is still of great significance. Metal cutting fluid is widely used in machining process to ...
