Cyclone filter

Abstract

According to an embodiment of the present disclosure, a cyclone filter is provided, including a pressure tank, which is provided with an inlet, a clean water outlet, and an impurity outlet; a filter pipe and a spiral filter pipe surrounding the filter pipe are arranged in the pressure tank. The provided swirl channel, wherein the filter pipe is in communication with the clean water outlet, the swirl channel is in communication with the inlet and guides the fluid to be purified flowing into the inlet to form a swirl flow, and the fluid to be purified passes through the swirl channel The impurities are separated, and the fluid from which the impurities are separated flows into the filter pipe, the fluid filtered by the filter pipe flows out from the clean water outlet, and the separated impurities flow out from the impurity outlet. The cyclone filter of the present disclosure is not limited by size in terms of filtering effect, and has low energy consumption. It can also automatically clean the inside of the pressure tank, which improves the automatic operation level of the equipment and makes the cyclone filter more convenient to use .

Description

technical field [0001] The present disclosure relates to a water treatment device, in particular, to a cyclone filter. Background technique [0002] The techniques for separating particulate matter from liquid generally include flocculation, sedimentation, cyclone, filtration and separation, etc. Size and separation efficiency are limiting factors for various separation systems. Flocculation and sedimentation techniques require settling tanks and long settling times. Although the cyclone device occupies a small area, the existing cyclone device has problems such as large energy consumption and unstable classification quality. Although filtration separation can produce high-quality separation, dirt is easy to accumulate and needs to be cleaned up in time. [0003] The cyclone filter is a centrifugal separation device, which is generally used for the treatment of sewage or wastewater. Cyclone filters separate grit, dirt, mud, humus, vegetation and other solids from the wat...

AI Technical Summary

Problems solved by technology

However, on the one hand, due to the impact of the water flow on the deflector, this method will cause a large energy loss; on the other hand, due to the influence of the size of the equipment and the size of the centrifugal force, the separation effect of impurities is unstable and difficult to control
