The filtering equipment for vacuum pumping and dewatering needs to be connected with a vacuum pump to provide dewatering power, and a gas-liquid separator needs to be arranged between the filtering machine and the vacuum pump to separate filtrate from air. In the current concentrating mill, a gravity liquid discharge pipe is generally adopted as a gas-liquid separator, and the gravity liquid discharge pipe and a filter are required to be arranged on a platform with the height of more than 10 meters so as to overcome the influence of atmospheric pressure on filtrate discharge and prevent filtrate from entering a vacuum pump from an air outlet of the gravity liquid discharge pipe to pollute working liquid of the vacuum pump and damage the vacuum pump; and adopt gravity flowing back, in order to prevent filtrate refluence, must set up the water seal case in the below of filtrate jar, when the filter cloth damages, the fine particle mineral gets into the water seal case along with the filtrate, easily causes the jam to lead to final filtrate to get into the vacuum pump along with the air, cause vacuum pump working fluid quality of water to change, also cause the damage to the vacuum pump. In addition, the gravity drainage mode is adopted, so that not only is the height of a factory building greatly increased and the capital investment increased, but also the energy consumption required by filtering ore feeding is greatly improved. Because the filter is a gas-water mixture, if a water pump is added to the gas-water separation device to pump water, air is easily pumped into a water pump station, cavitation is caused, and therefore the pump is damaged. Therefore, research and development of a forced drainage gas-liquid separator for filtering operation of concentrating mills, which can realize high-efficiency separation of gas and liquid and forced drainage, prevent damage of a vacuum pump and cavitation of a drainage pump, is necessary.
