Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a self-cleaning filtering device for farmland water conservancy facilities. Background Technique

[0002] In farmland water conservancy projects, the filtration of irrigation water is a crucial link. At present, there are some problems with the existing filtration devices for farmland water conservancy facilities. For example, traditional filtration devices often have a simple structure. For instance, some filtration equipment only uses a single filter screen. In farmland irrigation, the water source may contain various impurities, such as sediment, weeds, small soil aggregates, and organic debris remaining in the agricultural production process. A single filter screen is difficult to comprehensively and effectively filter these complex impurities, resulting in some impurities entering the irrigation system, which may clog irrigation equipment such as sprinkler heads and drip irrigation pipes, affecting the uniformity and efficiency of irrigation, and thus affecting the growth of crops. Therefore, some water conservancy self-cleaning filtration devices have emerged on the market.

[0003] For example, the utility model patent with the patent number CN202420290293.0 discloses a self-cleaning filtration device for water conservancy projects, including a bottom plate. The left side of the top of the bottom plate is fixedly connected with a support column, and the top of the support column is fixedly connected with a filtration box. This solution conveys sewage to the inside of the filtration box, filters larger impurities in the sewage through a filtration grille. After the sewage is filtered by the filtration grille, it is conveyed to the inside of the treatment box through a connecting pipe. Chemical agents are put in through a feeding pipe, and a stirrer is started, so as to be able to neutralize the sewage inside the treatment box. The sediment deposited inside the filtration box enters the inside of the sewage discharge pipe. The motor is started through the controller, the motor drives the transmission rod to rotate, the transmission rod drives the driving gear to rotate, the driving gear drives the driven gear to rotate, and the driven gear drives the screw rod to rotate, so as to be able to timely discharge the sediment inside the feeding pipe and avoid clogging.
