The invention relates to an online filtering and recycling method for diamond wire cutting liquid. The online filtering and recycling method comprises the following steps: 1, new cutting liquid with a set amount is prepared into a liquid mixing barrel according to the volume ratio of cutting stock solution to water being 400: (1.5-1.8); 2, the cutting liquid in the liquid mixing barrel is added till the liquid level height of a cutting liquid cylinder reaches H1; 3, after the cutting machine starts to work, a timer is used for timing to the time T, the cutting hydraulic cylinder discharges liquid to a filtering barrel, and the liquid level in the cutting hydraulic cylinder is reduced to H2; 4, when the liquid level in the liquid storage tank reaches H3, a second liquid drainage pump at a liquid outlet of the liquid storage tank is opened till the liquid storage tank is emptied; meanwhile, water and the cutting stock solution are added into the solution mixing barrel according to the volume ratio of 400: (1.5-1.8), the volume ratio of the added filtrate to the water is 1: 1, and recycling filtrate is prepared after mixing; and 5, liquid is added into the cutting liquid cylinder through the liquid mixing barrel to reach the liquid level height H1; and after the timer restarts timing to the time T, the process from the step 3 to the first 5 is repeated until cutting is finished.
Description
technical field [0001] The invention relates to the field of diamond wire cutting machines, in particular to a method for online filtration and recycling of diamond wire cutting fluid. Background technique [0002] The diamond wire cutting machine used for slicing monocrystalline silicon rods or polycrystalline silicon rods needs to use cutting fluid to lubricate and cool the diamond wire, and to clean and disperse the silicon powder particles on the steel wire. During the cutting process, it is necessary to strictly control the silicon powder in the cutting fluid Concentration, in the prior art, when cutting monocrystalline silicon or polycrystalline silicon rods, the cutting fluid is generally a cutting fluid that is mixed with water and cutting stock solution after loading and unloading once cutting. As the cutting progresses, the silicon in the cutting fluid The higher and higher the content of crystal particles, the cleaning effect on the diamond wire will gradually bec...
