Description
Technical Field
The invention relates to the technical field of cultivation, in particular to a modular micro-filter with an independent middle shaft support and an oversized ratio of length to diameter.
Background
The united nations Food and Agriculture Organization (FAO) report shows: with the increasing world population, the average human consumption demand for fish food increases from 9.0 kg in 1961 to 20.2 kg in 2015, with a preliminary estimate of about 20.5 kg in 2017. However, this increase in demand is no longer sustained by fishing fisheries that have maintained a steady level, but by aquaculture. The average growth rate of world aquaculture production from 2009 to 2014 is 23.5%. Currently, approximately 44% of the consumer fish worldwide are farmed, and this proportion is expected to reach 52% by 2025. In order to meet the consumption demand, in recent years, a recirculating aquaculture system is developed rapidly due to the advantages of high culture density, high yield, food safety, water and soil resource conservation, sustainability and the like.
During the cultivation process, due to the continuous accumulation of wastes such as residual baits and feces, harmful suspended solid particles are generated in the system, and the solid particles may contain harmful components such as nitrogen, phosphorus, pathogens and the like which can damage the environmental quality and harm the cultivated objects and the human health. This makes the solid-liquid separation an important process in the treatment process of aquaculture water. The rotary drum type micro-filter can intercept suspended solid particles in the aquaculture sewage through a micro-pore screen on the surface to achieve the purpose of solid-liquid separation.
At present, domestic drum type microfilter equipment is still in the stages of low flow (below 200m 3/h) and empirical design and manufacture, the efficiency and market competitiveness are reduced by a simple and rough operating mode of the microfilter, the problems of power consumption, large water consumption and the like exist, the economic applicability is poor, and the actual requirements of users are difficult to meet. Most of the existing driving modes of the rotary drum of the micro-filter are motor side-mounted driving, and when the water level rises or a system fails, the rotary drum of the micro-filter is submerged by water. In addition, backwashing of the microfiltration machine generally has two modes: timing and level methods. The timing method sets the start-stop time of the micro-filter through a time relay, but the content of the particulate matters in the water body is changed, particularly 1-2 hours after the breeding objects ingest, the timing method cannot be adjusted according to the content of the particulate matters, and the backwashing is easy to overflow in time or over-backwash. But the timing method can show the practicability when the liquid level method has problems. The liquid level method is through the liquid level switch in the microstrainer rotary drum monitor liquid level height thereby control the opening of microstrainer stop, compare in the timing method more reliable, but when liquid level switch broke down, if do not have the comparatively economic mode that can deal with this kind of condition, can lead to the microstrainer to in time influence follow-up water treatment process to the filtration of solid particle thing, and then influence entire system's performance. Therefore, a control system with a plurality of operation modes coexisting needs to be designed. Under the trend that industrial circulating water culture and pond engineering circulating water culture develop towards large-scale and standardized directions, the research and development of a large-flow intelligent rotary drum type micro-filter are imperative.
Relevant documents such as national agricultural sustainable development plan (2015 + 2030), guidance of accelerating the structure adjustment of fishery transformation in the department of agriculture, national fifth year plan of fishery development, agricultural equipment development action plan (2016 + 2025), and the like, indicate that: the key technology of intelligent regulation and control and equipment guarantee of the aquaculture environment is broken through, and equipment such as facility culture water quality regulation and control, accurate feeding, mechanical management and control systems and the like are developed. Therefore, the research and development of the large-flow intelligent rotary drum type micro-filter are of great significance.
