Description

Technical Field

[0001] The invention relates to the technical field related to photovoltaic silicon wafer cutting machines, and in particular to a cutting fluid dewatering mechanism for photovoltaic silicon wafer cutting machines. Background Art

[0002] The online recovery technology of mortar in silicon wafer cutting has begun to rise in China. More and more manufacturers have begun to purchase equipment to recycle mortar by themselves, but the moisture in the recovered cutting fluid will increase with the number of recycling times. Although different models have different requirements for the upper limit of the water content of the cutting fluid, the lower the water content in the cutting fluid, the higher the product qualification rate. Now many manufacturers specializing in recycling mortar use distillation equipment to distill the separated cutting fluid, but the existing distillation equipment is relatively expensive, and has low thermal energy utilization, serious waste, and is time-consuming, which is not conducive to use.

[0003] The cutting fluid dehydration device used for silicon wafer cutting machines in the prior art has a complex structure and high production cost. In addition, the dehydration efficiency of the cutting fluid dehydration device in the prior art is low. The supplied cutting fluid is dehydrated in a distillation chamber. Since the distillation chamber is large in size, the temperature rise of the cutting fluid in the distillation chamber is relatively slow, resulting in low dehydration efficiency of the cutting fluid dehydration device in the prior art. In order to overcome the above-mentioned defects, reference can be made to a cutting fluid dehydration structure for a silicon wafer cutting machine disclosed in the prior art (application number CN201510639958.X, application date 2015-09-30 Chinese patent). The dehydration structure is connected to the heating steam pipe through the exhaust pipe, and the drain pipe is connected to the heating water pipe. The heating steam pipe and the heating water pipe are both coiled in the preheating box. The water vapor discharged from the heating box and the heated cutting fluid are led into the heating steam pipe and the heating water pipe, and the cutting fluid in the preheating box is preheated, saving energy. At the same time When the cutting fluid in the preheating box is preheated, the water vapor in the heating steam pipe and the cutting fluid in the heating water pipe will be cooled by the cutting fluid in the preheating box, and the water vapor and cutting fluid discharged from the exhaust nozzle and the water discharge nozzle are at low temperatures; and a cutting fluid dehydration device for a silicon wafer cutting machine disclosed in the prior art (application number CN201510643956.8, application date 2015-09-30 Chinese patent) can be referred to. The dehydration device is coiled in the inner cavity through the exhaust pipe and the water outlet pipe. During actual use, the dehydrated cutting fluid and water vapor are discharged from the water outlet pipe and the exhaust pipe respectively. The exhaust pipe and the water outlet pipe coiled in the inner cavity can preheat the unheated cutting fluid in the inner cavity, and the temperature of the water vapor in the exhaust pipe and the cutting fluid in the water outlet pipe is reduced during the preheating process, thereby improving the dehydration efficiency of the cutting fluid and avoiding scalding the operator by the cutting fluid or water vapor, thereby improving the safety performance of the cutting fluid dehydration device.

[0004] Although the above device can solve the problem of speeding up the work of cutting fluid, in actual work, especially when heating the cutting fluid containing water, a lot of time is needed to heat it. When the liquid is replaced again, a lot of time will be wasted by distillation.
