Control circuit of magnetized liquid device

Abstract

The invention is about a pilot circuit of liquid magnetizing device which includes rectifying and filter circuit, switch circuit, energizing circuit and energy-conducting circuit. The switch circuit contains at least one power transistor, every power transistor works in on and off state, during the period when the power transistor is broken-over; the pulse power source is exerted to the magnet exciting coil. The characteristic of the circuit: when the power transistor changes from break-over to cut-off, the energy stored in the magnetic field goes back to the filtering capacitance, when the power transistor is broken-over again, the electric charges is utilized again to become the magnetic energy in the coil so the invention has quite little energy expenditure. The advantages of the invention: the pulse magnetic field in the invention can improve the magnetizing efficiency and decrease the energy expenditure; the control circuit in the invention can decrease the consumed power in pilot circuit, extend the service life of the pilot circuit as well as decrease the cost.

Description

technical field [0001] This invention relates to control circuits, in particular to control circuits for magnetized liquid devices. Background technique [0002] The magnetized liquid has been widely used in various fields because of its smaller molecular clusters, higher penetration, solubility, oxygen content, and conductivity than the liquid before magnetization. Magnetized water is the main For example, it has the advantages of dissolving scale and increasing the yield of agricultural products. [0003] Traditional devices for magnetizing liquids usually use permanent magnets, DC fixed magnetic fields, power frequency alternating magnetic fields, or quasi-resonant alternating magnetic fields to magnetize liquids. [0004] However, the magnetization device using permanent magnets, DC fixed magnetic fields, and power frequency alternating magnetic fields has a large volume, and the magnetic field strength of the permanent magnets is invariable. Although the magnetic field...
