Water purification pretreatment pipeline structure

Abstract

Belonging to the technical field of water purification equipment, the invention provides a water purification pretreatment pipeline structure. The water purification pretreatment pipeline structure comprises a pretreatment filter core disposed between a water pump 2 water inlet end and raw water, and a pretreatment loop arranged on the water pump water inlet end and a water outlet end, the pretreatment loop includes a pretreatment water tank disposed on the water inlet end and water outlet end of the water pump, and a first valve and a second valve that are arranged on two ends of the pretreatment water tank, also a water level induction signal source is disposed in the pretreatment water tank. The water purification pretreatment pipeline structure provided by the invention is equipped with the pretreatment filter core for preliminary filtration of raw water and prevention of impurities from entering the water pump and affecting normal operation of the water pump; the pretreatment loop disposed at two ends of the water pump ensure smooth water purification after slight blocking of the pretreatment filter core, and the adaptability is higher; also the service life of the pretreatment filter core can be judged according to an induction time difference of the water level induction signal source, the judgment method is more convenient and accurate, and the water purification is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a water purification pretreatment pipeline structure. Background technique [0002] Water purification equipment is favored by consumers due to its low cost and high filterability. For water purification equipment without pressure at the water inlet, the raw water does not pass through the pretreatment system, and the raw water directly enters the post-filtering system through the water pump to achieve Purification of raw water. [0003] Because the raw water has not passed the pretreatment system, the particles or hairs in the raw water enter the water pump of the water purification system, causing the pump to work abnormally (working pressure loss), which cannot meet the working requirements of water production, thus affecting the water purification Effect. [0004] To sum up, the current water purification equipment has the problem that impurities in the...

Problems solved by technology

[0005] In view of the above-mentioned problems in the prior art, it is now intended to provide a water purification pretreatment pipeline structure, to set a pretreatment filter element between the raw water and the water inlet end of the water pump, and between the water inlet end and the water outlet end of the water pump Setting up a pretreatment circuit not only realizes the initial filtration of raw water, prevents impurities from causing abnormal operation of the water pump, but also prevents the problem of insufficient suction of the water pump caused by the slight blockage of the pretreatment filter element, thus ensuring the smooth progress of the water purification process. Improve the water purification effect, and at the same time determine the service life of the pretreatment filter element according to the response time of the pretreatment circuit, thereby reminding the user whether to replace the pretreatment filter element to ensure the quality of water purification
