Description

Double-tank agricultural irrigation water filtering device with back flushing function Technical Field The utility model relates to agricultural irrigation equipment, in particular to a double-tank agricultural irrigation water filtering device with backwashing function. Background The agricultural irrigation water is generally taken from natural water flows such as stream water and mountain spring water, so that the irrigation water is mixed with a lot of sediment, small broken stone and other impurities, the irrigation water is further required to be added with fertilizer, fermentation powder and other substances, more granular impurities generally exist in the fertilizer and the fermentation powder, and the irrigation water is required to be filtered through a filtering device firstly in order to avoid the blockage of the impurities to an irrigation pipeline and a water outlet. The traditional filter device is generally provided with a filter tank, a filter assembly is arranged in the tank body, irrigation water is fed into the filter tank and is filtered by the filter assembly and then is fed out, after a certain impurity is stacked in the filter tank, the filter assembly is required to be disassembled for cleaning, the operation is very troublesome, time and labor are wasted, the tank body capacity of a single filter tank is limited, the filter efficiency is limited, high-efficiency filter water supply is difficult to realize, in addition, some filter devices capable of being automatically cleaned are also arranged on the market, but the whole structure is quite complex, in the actual use process, the cleaning effect of the internal impurity is also poor, and the user use experience is poor. Disclosure of utility model In view of the shortcomings of the background art, the technical problem to be solved by the utility model is to provide a double-tank agricultural irrigation water filtering device with backwash for solving the problems. For this purpose, the utility model is realized by adopting the following scheme: The double-tank agricultural irrigation water filtering device with the back flushing function comprises a water inlet pipe and a water outlet pipe and is characterized by further comprising a first filtering tank and a second filtering tank, wherein filtering components are arranged in the first filtering tank and the second filtering tank, so that filtered impurities are located between the filtering components and the inner wall of the filtering tank, the water inlet pipe is communicated with the first filtering tank through a first guide pipe, the water inlet pipe is communicated with the second filtering tank through a second guide pipe, a first waste discharge pipe communicated with an inner cavity of the first filtering tank is arranged on the outer side wall of the first filtering tank, a second waste discharge pipe communicated with the inner cavity of the second filtering tank is arranged on the outer side wall of the second filtering tank, the first filtering tank is communicated with the water outlet pipe through a third guide pipe, a first on-off control valve is arranged corresponding to the first guide pipe, a second on-off control valve is arranged corresponding to the second guide pipe, a third on-off control valve is arranged corresponding to the first waste discharge pipe, and a second on-off control valve is arranged corresponding to the second waste discharge pipe. The two ends of the water inlet pipe are provided with water inlets, and the two ends of the water outlet pipe are provided with water outlets. A reinforcing pipe is arranged between the water inlet pipe and the water outlet pipe, and two ends of the reinforcing pipe are tightly attached to the outer side walls of the water inlet pipe and the water outlet pipe. The first on-off control valve, the second on-off control valve, the third on-off control valve and the fourth on-off control valve are manual ball valves. The filter assembly comprises a filter screen, a single opening structure is enclosed by the filter screen, and the single opening is communicated with the third flow guide pipe and the fourth flow guide pipe. The filter screen encloses into the cylinder form, just single opening is located the one end of cylinder form. According to the double-tank agricultural irrigation water filtering device with backwashing, through the arrangement of the two filtering tanks, the connection of the water inlet pipe and the filtering tank is achieved by the arrangement of the first guide pipe and the second guide pipe, the connection of the filtering tank and the water outlet pipe is achieved by the arrangement of the third guide pipe and the fourth guide pipe, the double-tank agricultural irrigation water filtering device can achieve simultaneous filtration, and the filtering efficiency of the double-tank agricultural irrigation water filtering device is effectively improved.
