One-pump multipurpose zero discharge self-cleaning water purifier

Abstract

The invention belongs to the field of water purifiers and discloses a one-pump multipurpose zero discharge self-cleaning water purifier. A three-way four-way electromagnetic valve, electromagnetic three-way reversing valves and a water return pressure tank technology are integrated, and multi-filter element flushing and normal water production operation are realized through one pump; the path A, path B and path A-B in the three-way four-way electromagnetic valve respectively execute raw water supply, water return utilization and daily water transport tasks; the three-way four-way electromagnetic valve and the electromagnetic three-way reversing valves are matched into a staggered closed working condition mode; the electromagnetic three-way reversing valves are arranged at two ends of a high-pressure pump and filter elements, so that different paths are opened and closed, and multi-filter element flushing and normal water production operation can be implemented; each path of the electromagnetic valve is attached to a one-way valve shaped like a Chinese character quan; and the water return pressure tank integrates the water production and self-flushing operations to return water and is communicated with a domestic pipeline through the path B, and the water serves as domestic water again. According to the one-pump multipurpose technology of the water purifier, the membrane blockage problem confusing the industry for a long time is solved, zero discharge water production is realized, the water resources are fully utilized, and the environment-friendly and energy-saving effects are obvious.

Description

technical field [0001] The invention belongs to the field of water purifiers, in particular to a one-pump multi-purpose non-discharging self-cleaning water purifier. Background technique [0002] The water production rate of the water purifier is between 1:4----1:1. In other words, the water purifier has a large part of the treated residual water in the water production process. Because this residual water is still good domestic water, it is a great waste to discard it, and it is also difficult to recycle it. Repeated filtration, increase the water production rate, and set up another container for storage... In short, the troublesomeness of backwater treatment is self-evident; if it is directly discharged into the sewer, it is not a national policy to waste precious water. [0003] Purpose of the present invention, solve above-mentioned difficult problem exactly, open a kind of water purifier with self-rinsing and multi-purpose function of a pump to the society. Contents ...
