Abstract

The invention relates to an intelligent balance draining device, applying to a device utilizing vacuum for a solid-liquid separation. In an intelligent balance draining system of a vacuum filter, a vacuum pump 8 is connected with a port on an upper end of a draining tank 7 by a hose 9; the port on a side face of the draining tank is connected with a vacuum filter 3, which constitutes a steady vacuum system; the invention is characterized in that the intelligent balance draining system comprises an energy saving auxiliary draining system; a filtrate pump 4 is connected with the draining tank 7 by a pipeline; another end of the filtrate pump 4 is connected with an automatic drain valve 1 by the pipeline; the automatic drain valve 1 is connected with a gas nipple 6 on the draining tank by a hose 5. The invention has the following advantages: 1. the sealing effectiveness is good, which guarantees the stability of the vacuum system and reduces the energy consumption of the vacuum pump; 2. a fluid level gauge is not needed to measure the liquid level; depending on the auxiliary draining system, the liquid level is measured; and the height of the automatic valve port and the filtrate pump body is controlled; the liquid is always in the pump, which can not lead the pump start up without the liquid and saves the production cost of the auxiliary draining system; 3. the structure is simple, thereby reducing the maintenance cost and decreasing the labour intensity; 4. the mounting height is not required, thereby saving the construction cost of factory buildings.

Description

technical field

[0001] The invention relates to a novel intelligent balanced liquid discharge device in vacuum dehydration equipment, which is applied to equipment for solid-liquid separation using vacuum, and is specifically a negative pressure liquid discharge device. It belongs to the technical field of vacuum filters. Background technique

[0002] Vacuum filters use negative pressure to separate solids and liquids through filter media. During work, solids and liquids are adsorbed to the surface of the filter medium at the same time, solid particles are trapped on the surface of the filter medium, and the liquid passes through the filter medium into the pipeline with negative pressure and the drain tank. Since the drain tank is connected to the vacuum pump, the vacuum pump is used to The suction creates a negative pressure, which creates a pressure difference between the vacuum system and the outside world, thereby achieving the purpose of filtration.
