Description

Electromagnetic cleaner

The utility model belongs to the antiscale and the scale removal field of boiler, and specifically the utility model relates to a kind of electromagnetic cleaner.

The antiscale of boiler and scale removal are global long-standing problems, and descaling methods such as traditional acid wash, ion-exchange are all taken a lot of work, effort, cost height, effect are bad.Studies have shown that: by the electromagnetic field of high frequency, under the situation of the original chemical composition that does not change water, the physical property of water is changed, thereby change the surface tension of water, reach the descaling and antiscaling effect.

Existing electronic scale remover all adopts the main and submachine structure.Main frame is an electrical appliance part, and the machine of paying is a mechanical part.Wherein mechanical part is made up of central electrode, electrode protection medium and a pair casing.Central electrode is a utmost point, and paying casing is another utmost point.There is following major defect in this kind structure: 1) because the machine of paying is equivalent to the part that a big electric capacity becomes host circuit, interrelated during main and submachine work, so poor stability, homogeneity is poor; 2), need in addition media protection, so the most losses of the field energy that two interpolars produce on medium, rather than act on processing water, so actual efficiency is low because of central electrode is immersed in the water; 3) existence of central electrode certainly will occupy certain space, and current and water system are caused resistance, so be unfavorable for the normal stable operation of water system and realize computer controlled automatic.In addition, existing electronic scale remover complex structural designs, processing and debugging trouble, equipment is installed clumsy.Low, actual effect difference and fragile etc. equipment life is arranged again, and these must limit its application and development in more areas.

The purpose of this utility model is the above shortcoming that overcomes existing descaler, and the electromagnetic cleaner of a kind of reasonable in design, easy for installation, high efficiency is provided.

The utility model electromagnetic cleaner is made up of electrical appliance part and mechanical part, and wherein mechanical part adopts the mode that glass tube twines inductance coil outward, makes processed water directly by this glass tube, is subjected to the electromagnetic field effect of inductance coil and processed.This design makes energy act on processing water to greatest extent, and water system is not produced any resistance.Simultaneously this kind mode also make electrical appliance part and mechanical part work relatively independent, do not disturb mutually, and then improved the stability and the homogeneity of circuit, prolonged the service life of complete machine.Mechanical part design considerations networking limits flow velocity, flow formula (G=900 π d ²Pv, wherein G: the discharge T/h of pipeline section; D: water inlet pipe and water outlet pipe diameter mm; P: the density T/m of water ³The flow velocity m/s of water) and the size dimension of definite mechanical parts such as holdup time of processed water v:.The glass tube two ends are by the sealing of screw-threaded coupling pad and rubber gasket, with being threaded, weld together between support flange and shell between lock washer and support flange.The visual water system pipeline situation that connects between complete machine and water system adopts screw thread to connect or flange connects.

With the electrical appliance part that the mechanical part of electromagnetic cleaner of the present utility model adapts, the preferred integrated circuit that adopts is made oscillator on circuit design, with the VMOS high-power FET as power tube.The advantage of this circuit design is: switching speed fast (10nS-100nS), high current amplification factor (10 ⁸-10 ⁹), have excellent in stability, favourable identity, simple and reliable characteristics.

Describe the utility model electromagnetic cleaner below in conjunction with accompanying drawing in detail with a specific embodiment.

Fig. 1 is the front view of the utility model electromagnetic cleaner.

Fig. 2 is the side view of the utility model electromagnetic cleaner.

Fig. 3 is the circuit theory diagrams of the utility model electromagnetic cleaner electrical appliance part.

The implication of same numeral is identical among the figure, and the implication of each label is:

The 1-mechanical part, the 2-electrical appliance part, 3-connects support, 4-inductance coil, 5-glass tube, 6-support flange, 7-seal washer, 8-lock washer, the shell of 9-mechanical part.

With reference to Fig. 1, Fig. 2, the utility model electromagnetic cleaner is made up of mechanical part (1) and electrical appliance part (2), by connecting support (3) both are connected, wherein mechanical part (1) is made up of glass tube that is wound with inductance coil (4) (5) and the shell (9) that is welded with support flange (6).By seal washer (7) and lock washer (8), glass tube (5) is fixed in the shell (9).Glass tube (5) is gone up the inductance coil (4) that twines, and its two ends are passed shell (9) and upward linked to each other with electrical appliance part (2) in the hole of suitable position.

With reference to the circuit theory diagrams of the electrical appliance part (2) of the utility model electromagnetic cleaner of Fig. 3, this circuit is divided into power supply, vibration, power output, state and indicates four parts.Wherein oscillating part adopts Schmidt's ungated integrated circuit, and power output part adopts the VMOS high-power FET, and make and on inductance coil L1, form non-sinusoidal alternating current, space formation non-sine AC magnetic field-be the multi-frequency alternating electromagnetic field.Inductance coil L1 among Fig. 3 is the inductance coil (4) among Fig. 1.

The complete machine operation principle of the utility model electromagnetic cleaner is as follows: this electromagnetic cleaner is installed between the water-supply line of watering equipment, behind power connection, control circuit work, around glass tube, produce the multi-frequency alternating electromagnetic field by the inductance coil outside glass tube, and with tube hub part field intensity maximum, all act on the waterborne of this pipe of flowing through, water is because of intensifying the water that becomes upper state, thereby original interaction property between the mineral matter molecule of easy fouling and molecule or micel in the change water, make the water quality that enters watering equipment can not tie hard scale and be flocculent deposit in container bottom, simultaneously under the effect of electromagnetic field, old dirt chaps loose gradually and comes off voluntarily, and reaching has dirty scale removal, effect and the effect of not having dirty antiscale.

The utility model can be widely used in the descaling and antiscaling of various watering equipments such as the boiler, tea-bath furnace, cooling water system, air-conditioning system, heat-exchange system, solar energy system of industrial and mineral enterprises and institutions.Its extensive use will bring very big benefit to Human's production and life.And, prolong service life of equipment performance significant role to energy-conservation, water saving, economize on electricity, saving steel.
