Hydrodynamic filter for micro-irrigation

Abstract

The invention discloses a hydrodynamic filter for micro-irrigation. The hydrodynamic filter comprises a central transmission shaft, one end of the central transmission shaft is fixedly provided with a transmission part used for driving the central transmission shaft to rotate, and the other end of the central transmission shaft penetrates into a filtering and cleaning part and is fixedly connected with the filtering and cleaning part. A power assembly of the filter can utilize water flow to provide rotating power, so that a reliable source of the power is ensured, and energy is saved; meanwhile, the filter is based on the Archimedes spiral theorem, and impurities are pushed towards the water outlet direction along the central transmission shaft through a spiral brush and then discharged out of the filter; and meanwhile, water flow and impurities are separated through a filter assembly, and the impurities are separated in a filter screen to ensure effective filtration, so that the device has the advantages of few accessories, small abrasion, durability, low manufacturing cost, convenience in operation and management, difficulty in blockage, energy conservation, emission reduction, rapidness and high efficiency.

Description

technical field [0001] The invention relates to the field of filtering science and technology, in particular to a hydrodynamic filter, in particular to a micro-irrigation hydrodynamic filter. Background technique [0002] Compared with traditional bottom irrigation (soaking tanks), micro-irrigation can save 50%-60% of water resources, and generally reduce power consumption by about 30%. It has the advantages of increasing production, saving water, saving fertilizer, and saving labor. , is currently the most water-saving irrigation technology. As an emerging irrigation technology, micro-irrigation also has outstanding advantages in promoting agricultural automation. However, micro-irrigation has high requirements on water quality, which is specifically manifested in the strict filtration of irrigation water. [0003] At present, there are many types of filters for micro-irrigation, commonly used are mesh filters, laminated filters, sand filters and centrifugal filters (hydr...

AI Technical Summary

Problems solved by technology

[0005] 1. Today's micro-irrigation filters mainly use electric energy as their power source, and the filter equipment is large in size, with many accessories and high management costs (need to build a dedicated management room with an area of ​​about 30-60 square meters, It not only occupies a large area, but also requires professionals to manage and maintain), and has high requirements for highly automated technical features such as sensors and controllers, which in turn leads to complicated manufacturing processes of filters, which eventually leads to more expensive;

[0006] 2. Filtration efficiency has always been an important and difficult problem for micro-irrigation filters to be remedied. In order to achieve the target value of water quality, it is sometimes necessary to combine multiple sets of different types of filters, which not only increases the cost of water quality filtration, but also increases the cost of sewage discharge. More water is wasted in the process
