Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal filtration, in particular to a centrifugal filtration device for water-saving irrigation. Background Art

[0002] Centrifugal filtration uses centrifugal force as the driving force. A suspension is added to a perforated drum with a filter medium (such as a filter screen or filter cloth). Solid particles are retained on the filter medium, and the liquid flows out through the filter cake layer. Finally, the filtration operation of separating the filtrate and the filter cake is completed. Water-saving irrigation methods usually include sprinkler irrigation and drip irrigation. In the process of water-saving irrigation, it is usually necessary to connect its pipes to the pipes at one end of the water pump, and then use the water pump to pump out water from the river or lake for irrigation. In order to prevent impurities such as sand, seaweed, etc. mixed in the water from clogging the irrigation device, a centrifugal filter device is usually used to filter it.

[0003] In the process of filtering with a centrifugal filter device, impurities such as sand, seaweed, etc. are usually precipitated into the interior of a grit tank for collection. However, the silt is easily adhered to the interior of the grit tank, and a large amount of water is required to flush the grit tank to complete the cleaning of the grit tank. The cleaning rate is slow and a large amount of water is wasted, which is not conducive to the cleaning of the grit tank and the use of the grit tank. Utility Model Content
