Description
Technical Field
The utility model belongs to the technical field of water quality filtration, and particularly relates to a header water-saving filtering device for irrigation.
Background
Because of the limited water resources in China, water is saved in many industrial fields, especially in the field of agricultural irrigation. At present, the agricultural irrigation form is gradually changed from the prior farmland drip irrigation into drip irrigation or micro-irrigation, so that the effective utilization coefficient of agricultural irrigation water is greatly improved, and the main structure of a drip irrigation system or a micro-irrigation system is a drip irrigation pipe or a micro-irrigation pipe. The drip irrigation pipe or the micro-irrigation pipe is fine in structure, the existing header water-saving filtering system is poor in filtering effect, the drip irrigation pipe or the micro-irrigation pipe is often blocked, the irrigation effect is affected, and therefore the requirement on the content of impurities in irrigation water is high. Therefore, for the existing drip irrigation system or micro irrigation system, the irrigation water needs to be filtered, so as to improve the efficiency of the drip irrigation system or micro irrigation system.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a water-saving filter device at the head part for irrigation, which comprises a water source water inlet pipe, a sand filter, a secondary filter, a blow-down valve, a blow-off pipe I and a farmland access pipe, wherein the water source water inlet pipe is connected with the sand filter through the water inlet pipe of the sand filter, a water outlet pipe of the sand filter is connected with a water inlet of the blow-down valve through the water inlet pipe of the secondary filter, a blow-off outlet of the blow-down valve is connected with the blow-off pipe I, a water outlet of the blow-down valve is connected with the secondary filter, and a water outlet pipe of the secondary filter is connected with the farmland access pipe.
The water source water inlet pipe is provided with a remote pressure gauge I, an exhaust valve I and a pressure release valve.
The sand and stone filter inlet tube is equipped with the butterfly valve, the butterfly valve is connected with blow off pipe II.
The water inlet pipe of the secondary filter is provided with a pressure gauge II and an exhaust valve II.
The sand and stone filters are connected in parallel in 2-3 stages, and the secondary filters are connected in parallel in 4-6 stages.
Compared with the prior art, the utility model has the following advantages: the utility model sequentially carries out sand filtration and secondary filtration, and carries out sewage disposal of the sewage disposal valve before secondary filtration, thus having good filtration effect; performing backwashing before the source water enters the sandstone filter to remove organic impurities and suspended matters such as moss and granular substances in the source water; meanwhile, a plurality of sand and stone filtering gases, secondary filters and blow-down valves are arranged in parallel, so that the treatment capacity of irrigation water is increased; by setting the valve, whether sand and stone filtration is performed or not is selected according to source water with different water quality, so that the early treatment period and the energy consumption are reduced; the control system can detect the water pressure in the pipeline in real time and carry out corresponding pressure relief action.
