Water circulation filtering device

Abstract

The invention discloses a water circulation filtering device and relates to the technical field of filtering, the water circulation filtering device comprises an air cleaning filter tank body, air cleaning filter paper layers, an oil spraying cleaning filter tank body and a water curtain oil filtering mechanism, wherein an isolation plate is horizontally fixed below the inside of the air cleaningfilter tank body; and the air cleaning filter paper layers are equally spaced and parallelly arranged between the isolation plate and a hollow water delivery pipeline. The port of the hollow water delivery pipeline is connected with an air tank circulating pipe; one side of the air cleaning filter tank body is provided with the oil spraying cleaning filter tank body; and the water curtain oil filtering mechanism is arranged above the inside of the oil spraying cleaning filter tank body. According to the water circulation filtering device, water filter processing of air is realized through theair cleaning filter tank body, and water filter processing of oil mist is realized through the oil spraying cleaning filter tank body. The arrangement of the air cleaning filter tank body and the oilspraying cleaning filter tank body expands the application range of the water circulation filtering device, increases applicable objects of the water circulation filtering device, improves the use effect and equipment utilization rate of the water circulation filtering device, and can achieve the purposes of saving water sources and reducing cost.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a water circulation filtration device. Background technique [0002] Filtration is a means to obtain high-quality products. Filtration is the process of purifying fluids through special devices. There are many ways to filter, and a wide range of material systems are used, such as solid-liquid, solid-gas, large particles, small Particles are common. [0003] As one of the most abundant resources in nature, water can not only supply human survival and life, but also be used as energy. Among the many uses of water, using water as a filter medium is a feasible and effective filtering method. [0004] Existing devices that use water to filter are few and far between. In many cases, the functions of devices that use water to filter are relatively single, there are fewer objects to filter, and the filtering effect is not obvious enough or the filtering effect is not good. These fact...

[0004] Existing devices that use water to filter are few and far between. In many cases, the functions of devices that use water to filter are relatively single, there are fewer objects to filter, and the filtering effect is not obvious enough or the filtering effect is not good. These factors lead to the use of water resources as When the filter medium is used, the waste is serious, and the cost of treating the used wastewater is also high
