Irrigation filtering apparatus

Abstract

The invention discloses an irrigation filtering apparatus. The apparatus comprises a primary filter, a water inlet pipe, a water return pipe, a water return valve, a connection pipe, a secondary filter, a water pump, a filter installation pipe and a water outlet pipe, wherein two ends in the axial direction of the connection pipe are respectively provided with an inlet and a first outlet, the sidewall of the connection pipe is also provided with a second outlet, the primary filter is connected with one end of the water inlet pipe, the other end of the water inlet pipe is connected with the inlet, two ends of the filter installation pipe are respectively connected with a water inlet of the water pump and the second outlet, the secondary filter is arranged in the filter installation pipe, the water inlet end of the secondary filter extends into the connection pipe and a flow gap exists between the water inlet end of the secondary filter and the inner wall of the connection pipe, one endof the outlet pipe is connected with a water outlet of the water pump, the water return pipe is connected with the first outlet, and the water return valve is arranged on the water return pipe. The two-stage filters filter irrigation water, the blocking or damaging of the water pump by impurities is prevented, the water flow takes away the impurities at the secondary filter by opening the water return valve, the impurities are self-cleaned, and thereby the continuous operation of the irrigation filtering apparatus is ensured.

Description

technical field [0001] The invention relates to the technical field of irrigation devices, in particular to an irrigation filter device. Background technique [0002] When watering crops, the water source is often not clean enough to cause debris to block the water pump, interrupt the watering operation, or even damage the water pump due to the inhalation of impurities such as sand and gravel. Manually cleaning the filter device of the water pump is not only a waste of manpower and material resources, but also The efficiency of irrigation operations cannot be guaranteed. For example, when reclaiming abandoned homesteads or abandoned factory buildings, the cleaning of irrigation water sources will be caused by factors such as domestic garbage accumulated in the process of living and a large amount of construction waste generated during building maintenance. The speed cannot be guaranteed, which leads to the fact that when the crops on the reclaimed abandoned homestead or aban...

[0002] When watering crops, the water source is often not clean enough to cause debris to block the water pump, interrupt the watering operation, or even damage the water pump due to the inhalation of impurities such as sand and gravel. Manually cleaning the filter device of the water pump is not only a waste of manpower and material resources, but also The efficiency of irrigation operations cannot be guaranteed. For example, when reclaiming abandoned homesteads or abandoned factory buildings, the cleaning of irrigation water sources will be caused by factors such as domestic garbage accumulated in the process of living and a large amount of construction waste generated during building maintenance. The degree of safety cannot be guaranteed, which makes it very easy to block the irrigation device or even damage the water pump when irrigating the crops on the reclaimed abandoned homestead or abandoned factory
