Description

Vertical electromagnetic water device

The utility model belongs to water treatment device.

Water mangetizer is widely used in recent years produces medical magnetized water, handles oiler feed and has prevented dirt, handles feedwater and improves condition of water quality etc.Its principle is to utilize magnetic field that former water is magnetized, and changes various ionic character in water molecules and the water.Existing water mangetizer mostly is to be magnetic cell with permanent magnet.Exist insufficient that magneticflux-density is little, water is magnetized, and growth magneticflux-density in time such as reduces gradually at shortcoming.Existing electromagnetism hydrophone mostly is the transverse magnetic field water mangetizer again, the application of the aspects such as medical treatment, beverage and boiler water filling that have that magnetic gap is narrow, that the liquid stream residence time is short, water is magnetized is insufficient, are unwell to the big flow magnetized water of needs.As ZL85203732 electromagnetic magnetized water device and ZL87200805 dual coil electromagnetic energy-saving appliance, be exactly this type.The coil of encouraging of the water mangetizer of these types is sealed in its housing in addition, makes the heat that himself produces be difficult for coming out, thereby can not use for a long time.

The purpose of this utility model:

It is long to develop a kind of magnetic gap of leaking water, and the time that water stops in magnetic field is also long, and the magnetic gap sectional area of water flowing is big, can handle the vertical electromagnetism hydrophone of big yield.

Content of the present utility model:

Vertical electromagnetism hydrophone is made up of rectifier and water mangetizer and under meter.Rectifier is that the 220V alternating-current is converted into galvanic equipment, and water mangetizer mainly is made up of magnet coil, magnetic conduction heel piece and intermediate receptacle three parts, is a magnetic loop with big air gap.

The design of this water mangetizer magnet coil, at first utilize the magnetic loop Ohm's law:

B＝NIμ ₀／L………… （1）

(the number of turn of N--coil in the formula; I--strength of current (ampere); B--magneticflux-density (Gauss); μ ₀Magnetic diffusivity in the=1.257--air; The height in L--gap (centimetre).) estimate the number of turn N of magnet coil.Then according to the height in gap and the height of sectional area of wire.Determine the height and the number of plies of magnet coil, and then can determine the external diameter of coil.Again with asking the integration type of solenoid magnet flux density to check:

B ₀＝ (μ _O·2π·NI)/((r ₁- r ₂)·10) en

………… （2）

(μ in the formula ₀Magnetic diffusivity in the=1.257--air; The total number of turns of N--magnet coil; I--strength of current (ampere); r ₁--the internal diameter of magnet coil (centimetre); r ₂--the external diameter of magnet coil (centimetre)), if when checking computation results does not meet design requirement, N suitably can be adjusted, calculate till meeting design requirement again again.

The sectional area of armouring yoke should be 1.1～2 times of sectional area in the magnet coil, adds behind the armouring that yoke to the offering of magnetic field, can make the magneticflux-density in the magnet coil increase by 2 times.

The type of cooling of coil is to utilize hollow core conductor to twine magnet coil, and water flowing is cooled off in hollow core conductor, when coil power is bigger, can divide several sections when lead is longer and cool off.The flow of water coolant calculates with following formula:

${\mathrm{Q\; =\; 8\times 10}}^3(\frac{\mathrm{P\; t}}{e}{\mathrm{DH)}}^{\frac{1}{2}}\mathrm{\dots \dots \; (3)}$

(Pt is the pressure (kilograms per centimeter of water coolant in the formula ²); E be hollow core conductor length (centimetre); Q be cooling water flow (centimetre ³/ second)), the temperature rise of water is determined with following formula:

△T _b＝ (W)/(4·186Q) ………… （4）

(△ T in the formula _bFor the temperature rise of water coolant (℃); Q be water coolant flow (centimetre ³/ second); The power of W--magnet coil (watt)).

Scope of design of the present utility model is:

Water amount: 20～300 ton per days;

The residence time of water: 2～10 seconds;

Magneticflux-density in the gap: 0～4000 Gauss;

Current consumption: 1.7～21.5 kilowatts;

Overall dimensions: external diameter φ 400～φ 660mm, height 380～500mm.

This water mangetizer input dc power produces the vertical magnetic field identical or opposite with current, and it is big to have a gap, magnetic field, the characteristics that the time that water stops is grown.The type of cooling is to utilize hollow core conductor to twine magnet coil, and water flowing is cooled off in lead, thereby the heat that can in time take away coil and produced, so water mangetizer can use for a long time continuously, can reach desired magneticflux-density by the adjusting electric current.The design load of the magneticflux-density in its gap and the deviation of measured value are no more than 10%.

This water mangetizer is applicable to that hospital and sanatorium produce magnetized water, is used for the treatment of and scientific research, prevents that for large medium-size boiler provides magnetized water boiler from playing dirt, provides the high-quality magnetized water for making wine and beverage industry.

Positively effect of the present utility model:

Water can be fully magnetized, and the water yield of processing is big, and magneticflux-density can be regulated, and the type of cooling is simple and easy to do, and can use continuously for a long time.
