Embodiment 1

[0040] Example 1, after the circulating grinding fluid produced by each grinding machine is collected in the circulation tank, it enters the inorganic membrane filtration system after being pressurized by the raw material pump, and the circulating grinding fluid flows through the inorganic ceramic membrane under the low pressure drive in the inorganic membrane filtration system On the surface of the membrane, water and the water-soluble substances of the grinding fluid pass through the inorganic membrane to form a permeate that flows out, enters the filtrate tank, and then is cooled and sterilized and pumped to each grinding machine point; the suspended abrasive particles in the circulating grinding fluid, the grinding wheel The ash and oil are intercepted and separated by the inorganic membrane to become concentrated liquid, and then the concentrated liquid is regularly discharged and collected, pumped to the concentrated liquid tank, the clear liquid, grinding debris and sludg...

Embodiment 2

[0044] Embodiment 2, the present invention can also recover useful grinding debris: suspended grinding debris particles, grinding wheel ash and oil in the circulating grinding fluid are intercepted and separated by the inorganic membrane to become a concentrated solution (dope) of a certain concentration, and then concentrated The liquid is regularly discharged and pumped to the concentrated liquid tank (V0704), the debris is settled and separated, the clear liquid is collected in the membrane emptying collection tank (V0706), and then returned to the circulation tank (V0701) by the pump, and then enters the circulation system, and the abrasive debris The sludge is discharged into recycling barrels. refer to figure 1 With Fig. 2, all the other are with embodiment.

Embodiment 3

[0045] Embodiment 3, the present invention can adopt the inorganic membrane tube in the inorganic membrane filtration system (UF0701), preferably adopt the inorganic ceramic membrane tube with filtration accuracy less than 0.3 μm, the interception rate to the superfine wear debris particle can reach 99%, can Useful grinding particles are recovered.

Abstract

The invention relates to an inorganic film, used to concentrated filter abrasion liquid, wherein it is characterized in that: the cycle abrasion liquid, via deposition, flows from tube to the cycle groove, via the pressure to flow the surface of inorganic film; the water and the soluble matter penetrates the inorganic film to form the penetrated liquid to flow out to the filter liquid groove; then via adjusting the temperature and disinfecting, it is pumped into each grinder; the suspended particles, ash and oil of cycle abrasion liquid are stopped and separated via the film to be the concentrated liquid, to be discharge and pumped to the concentrated liquid groove; then depositing and separating, to feedback clear liquid to the system; and recycling the abraded bits. The invention has simple operation and lower cost.

Description

technical field [0001] The invention relates to a process of using inorganic membranes for centralized filtration of grinding fluid and patented equipment suitable for the process. Background technique [0002] With the development of human industrialization, the machinery manufacturing industry occupies a very important position in the national economy. The machinery manufacturing industry is based on the three major processing technologies of cutting, grinding and casting and forging. Among them, cutting and grinding have the highest application proportion, accounting for about 30% to 40% of the total labor in mechanical processing, and metal cutting and grinding fluids account for 52% of the total metalworking fluids. A large amount of energy and resources are occupied and consumed in the process of use, treatment and discharge, and the related costs account for about 30% of the total production and processing costs. [0003] Grinding has different characteristics from c...
