Description
Technical Field
The invention relates to the technical field of irrigation engineering equipment, in particular to a microfilter in a self-flow filtering mode.
Background
At present, most of farmland irrigation still adopts a traditional flood irrigation mode, water-saving irrigation is a development trend of agricultural irrigation, and irrigation technologies supported by drip irrigation water-saving technologies are popularized and applied on a large scale.
Drip irrigation is a form of agricultural high-efficiency water-saving irrigation, the drip irrigation is to transmit water to the field through a pipeline, irrigation water is dripped out of the pipeline by an irrigator-dripper of a micro flow channel on the pipeline to irrigate and water crops, the requirement of the water for the growth of the crops is ensured, the drip irrigation water is determined by the micro flow channel of the irrigator that impurities in the irrigation water must be filtered by a filter, and the non-blockage of the dripper and the continuous reliability of the irrigation are ensured. The basic requirements for drip irrigation systems are the continuity of the water supply and the source filtration process.
In the irrigation system that flows automatically, because the silt content at most water sources is higher, filter equipment is after long-term operation, and filterable impurity can be gradually attached to and form the impurity layer on the filter screen, just so influences the continuation of follow-up filter effect and filter equipment water supply like this. At present, the filter screen is generally detached manually for cleaning or the blocked filter screen is washed intermittently by a washing water pipe, so that the filter screen recovers the normal filtering function.
However, the manual removal of the filter net requires the filter device to be stopped first, and therefore the filter device cannot continuously supply the filtered clean water to the drip irrigation system. And the mode of intermittently scouring the filter screen by the backwashing water pipe is adopted, because the backwashing water pipe controls the flushing water pipe to scour the filter screen after detecting the blocking condition of the filter screen or the height change of the water level in the filter cylinder and other signals, therefore, the filter screen can be flushed by the flushing water pipe only under the condition that the filter screen is blocked to a certain degree, since the clogging degree of the filter net is gradually accumulated with the change of the filtering time and the state of the water source, before the blockage degree of the filter screen does not reach the blockage degree for controlling the opening of the flushing water pipe, the filter screen is in a partial blockage state, the partial blockage of the filter screen can also influence the water yield of the filter device, therefore, the water yield discharged by the filtering device is not constant but dynamically changed, and the requirement of a downstream irrigation system for supplying clean water with a continuously stable water yield to an upstream filtering device cannot be met.
