An energy-saving and fast water and dehumidification method for overflow micro-powder

Abstract

A fast energy-saving dewatering and dehumidifying method of overflow micro powder comprises the specific processes of short-time precipitation-centrifugal drying-flash distillation for dehumidifying-sieving-packaging. In the short-time precipitation process, eight sedimentation tanks as a group are used, four sedimentation tanks are main sedimentation tanks, each main sedimentation tank is provided with a vice sedimentation tank, main and vice sedimentation tanks are provided with stirring systems for stirring materials to meet the requirements of drying; in the centrifugal drying process, three times of throwing and three times of dehydration are used to complete the drying process; and finally, flash distillation for dehumidifying, sieving and packaging are performed. The fast energy-saving dewatering and dehumidifying method has the advantages of being simple in process, convenient in operation, full and rational in use of resources, labor and energy saving, and convenient for production of marketable products. Compared with a traditional process, a finished product can be produced ten days in advance, a lot of sedimentation time is saved, productivity is increased, a hard labor process of a starting material is avoided, energy waste in a drying process is saved, the thermal efficiency is improved by more than 35%, and the cost per unit is reduced by about 100 yuan.

Description

technical field [0001] The invention relates to a crystal material micropowder water classification technology, in particular to an energy-saving and fast water and dehumidification method for overflow micropowder. Background technique [0002] At present, the usual production process of crystalline material micropowder water classification is: crushing by crusher → ball mill (or Raymond machine, jet mill) reprocessing → iron removal → pickling → overflow classification → sedimentation → material removal → drying → sieving Loose → packing. Here we find the process of settling→lifting→drying. The advantage of the process is that the required facilities are simple and less investment. The disadvantage is that the site is large, and there are three outstanding problems. One is the long settling time, which generally takes 15 days; The labor intensity of the material is high; the third is that the drying thermal efficiency is low, usually 30-35%, and it is time-consuming, labor...

Here we find the process of settling→lifting→drying. The advantage of the process is that the required facilities are simple and less investment. The disadvantage is that the site is large, and there are three outstanding problems. One is the long settling time, which generally takes 15 days; The labor intensity of the material is high; the third is that the drying thermal efficiency is low, usually 30-35%, and it is a waste of time and energy to sum up.
