Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention:
[0023] figure 1 Schematically shows the structure of the beneficiation filtration drainage system. like figure 1 As shown, a drainage system for ore dressing and filtration provided by the present invention includes: a drainage tank 4 , a water sealing pool 5 , and a negative pressure drainage device installed between the drainage tank 4 and the water sealing pool 5 . The negative pressure liquid discharge device described in the present invention uses circulating water to generate negative pressure so that the liquid in the liquid discharge tank 4 can be smoothly discharged into the water seal pool 5, and the liquid discharge tank is enhanced under the premise of ensuring the original gravity liquid discharge advantage 4, and can reduce the height difference ...

The invention discloses a beneficiation filtering and draining system and method. The system comprises a negative pressure draining device which is mounted between a draining tank and a water seal tank and generates negative pressure by using circulating water, and the negative pressure draining device is connected with the draining tank and the water seal tank through a draining pipeline and a water outlet pipe. According to the beneficiation filtering and draining system and method, negative pressure can be generated by using the circulating water, liquid in the draining tank is smoothly drained into the water seal tank, the draining effect of the draining tank is enhanced on the premise of ensuring the beneficial effects of the original gravity draining, the height difference between the draining tank and the water seal tank can be reduced, and therefore the related capital construction investment is reduced.
Description
technical field [0001] The invention relates to the technical field of mineral processing and filtering equipment, in particular to a mineral processing and filtering drainage system and method. Background technique [0002] The filtration process commonly used in beneficiation engineering generally consists of main filtration device, vacuum system, gas-liquid separation and drainage system. [0003] Install a liquid drainage system before the water ring vacuum pump to prevent the water ring vacuum pump from inhaling the gas-water mixture, thus relying on gravity is called a gravity drainage tank. The gravity drainage tank has the advantages of simple structure and convenient operation. The disadvantage is that it is affected by the structural principle. Usually, the height difference between the drainage tank and the water seal pool needs to be at least 10m, so as to eliminate the water accidentally brought out during vacuuming and prevent backflow. In actual engineering, ...
