Water processor and automatic pole changing circuit thereof

Abstract

The invention relates to a water treatment device and an automatic pole changing circuit thereof. The water treatment device utilizes a sweep electromagnetic field for water treatment, is provided with a sweep electromagnetic field generator which can simultaneously generate a direct-current electric field and a sweep pulse electromagnetic field for water treatment; and frequency spectrum of the sweep pulse electromagnetic field can be continuously changed, thereby the device is suitable for water to be treated with various characteristics. Moreover, the device is also provided with the automatic pole changing circuit; after the water treatment device is operated for special time (for example, 100 hours), the automatic pole changing circuit is started and an anode and a cathode of the water treatment device are interchanged, namely the prior anode is changed into the cathode and the prior cathode is changed into the anode. At this moment, due to the action of an electric field force, scale deposit which is settled on the prior cathode and formed by calcium ions and magnesium ions is automatically fallen off and then exhausted from a drain along with water current.

Description

Technical field: [0001] The invention relates to a water treatment device and an automatic pole-changing circuit thereof, in particular to a water treatment device and an automatic pole-changing circuit for water treatment using a frequency-sweeping pulse electromagnetic field. Background technique: [0002] The use of electromagnetic fields to treat industrial and domestic water is a kind of physical water treatment. Its principle is to make water pass through electromagnetic fields, thereby breaking the bonding bonds of water in the state of large associations, and dissociating water into highly active single molecules or Water in a small association state, thereby changing the physical structure and characteristics of water, increasing the dipole moment of water molecules, changing the deposition state of sedimentary substances in water, and the physical properties of various ions, so as to effectively achieve scale prevention, scale removal, The purpose of sterilizing, a...

AI Technical Summary

Problems solved by technology

[0003] However, in the prior art, equipment that uses electric or electromagnetic fields to treat water often has such shortcomings, that is, during the water treatment process, when water flows between the positive and negative electrodes of the treatment equipment, the scaling substances contained in the water, namely calcium Ions and magnesium ions are adsorbed on the negative electrode due to the action of a DC electric field (the same principle as electroplating)

Therefore, after the water treatment equipment runs for a period of time, a thick layer of scale will form on the electrode plate, which will significantly reduce the treatment effect of the water treatment equipment.

In order to remove the scale on the electrode plate, it is necessary to stop the machine for maintenance, which is not only time-consuming and laborious, but also often uses chemicals for descaling, which will cause secondary pollution of the water body
