Centrifugal dual-filter-element filter

Abstract

The invention relates to a centrifugal dual-filter-element filter. The centrifugal dual-filter-element filter is characterized by comprising an enclosure, a filter apparatus and a self-cleaning apparatus, wherein the enclosure is composed of a shell, an end cover, an electric control box, a pressure gauge, an electric control sewage discharging port, a sewage discharging end cover and a reducer support, the filter apparatus is disposed inside the enclosure, and the self-cleaning apparatus is arranged in the filter apparatus. By adopting a composite dual-layer filter screen structure, water is driven by a reducer to generate a centrifugal action, so that the filter effect is improved, and the filter quality is improved; moreover, by utilizing the self-cleaning filter technology, impurities on a filter screen are back-washed in time, the water is filtered in a high-quality high-efficiency manner, filter holes are prevented from being blocked, and the working time of the filter is increased; and meanwhile, the damage to the filter screen caused by inconsistent pressure inside and outside the filter screen can be avoided.

Description

technical field [0001] The invention relates to a centrifugal double filter element filter. Background technique [0002] China is a country with relatively poor water resources, and the per capita water resources are less than 2200m 3 . In my country's vast rural areas, water resource shortage and waste coexist, water resource utilization efficiency is low, and environmental pollution is serious. From the perspective of ecological environment, groundwater is seriously overexploited, and domestic garbage is full of rivers, which makes the water flow capacity very poor, which is not convenient for water flow or flood discharge, and then makes every river in the countryside a smelly ditch, which brings great harm to crop irrigation. come to have a big impact. [0003] Agriculture is the foundation of the national economy, the guarantee for the sustainable development of China's economy and society, and plays a role that cannot be underestimated in the development of the nat...

Problems solved by technology

[0004] At present, the main problems of agricultural filters are: the filter device mostly adopts a single form of sand and gravel filtration in a single tank, resulting in poor filtration performance; moreover, manual backwash opening and closing valves are mostly used, and the technical level is low, even if it is fully automatic control. Using single-tank control technology and installing a single-layer filter element is prone to problems such as blockage of filter holes and tearing of small-hole filter elements, which cannot perform high-quality and effective filtration of polluted water and work for a long time, which in turn affects agricultural irrigation and other operations.
