Description

Technical Field

[0001] The utility model relates to the technical field of water purification, and particularly relates to a water purification pretreatment device. Background Art

[0002] With the pursuit of people for the quality of life, the water quality of drinking water has begun to attract much attention. Existing water purification equipment generally pre-treats water through various methods such as chemical coagulation and precipitation treatment, quartz sand and activated carbon mixed filtration treatment, PP cotton filtration treatment, and electrolytic separation treatment. However, the separation effect of the above methods on microorganisms and organic matters with smaller particles in water is average.

[0003] The patent with the application number "202410563069.9" applied by our company discloses a water purification device, including: a centrifugal cylinder, a centrifugal device is arranged in the centrifugal cylinder, a water purification outlet is opened above the centrifugal device, and a sewage outlet is opened below the centrifugal device; a plurality of water inlet modules, the water inlet module includes a connected atomization cylinder and the air pressure water hammer cylinder, the distance between a plurality of the atomization cylinders and a plurality of the air pressure water hammer cylinders is the same, and a plurality of the atomization cylinders are communicated with the centrifugal cylinder; by using the centrifugal device to remove the particulate matters in the atomized water molecules, and by arranging a plurality of water inlet modules, the atomized water molecules generate a resonance effect in the centrifugal cylinder, so that the separation effect of impurities, sediment, microorganisms and organic matters in the water mist is better. However, the water purification device of the above patent can only purify water sources with less impurities and sediment, such as river water, salt water, etc. If there are more impurities and sediment, directly purifying water through the water purification device of the above patent is likely to damage the water purification device itself and reduce the service life of the water purification device.

The diameter of the filter holes of the second filter element is smaller than the diameter of the filter holes of the first filter element. Water sources such as river water and salt water with more impurities and sediment flow into the first cavity from the water inlet end, and then are subjected to primary filtration of larger impurities through the first filter element, and then secondary filtration through the second filter element. The filtered water source flows to the water purification equipment through the inner cavity of the second filter element and the water outlet end for water purification, realizing the treatment of the water source before the water purification equipment purifies the water, preventing water sources such as river water and salt water with more impurities and sediment from damaging the water purification equipment itself and reducing the service life of the water purification equipment.
