Description

TECHNICAL FIELD [0001] The present invention relates to a multi-layer electromagnetic field generating module,

The present invention relates to an apparatus for improving performance of a multi-layer electromagnetic field generating module. To an apparatus for improving the performance of a multi-layer electromagnetic field generating module that controls the flow state in a pipe by applying an electromagnetic field to the inside of the pipe.

Dredged soils are sediments deposited in rivers and seas to secure the necessary soil and sand in the construction site. Dredged soils in rivers are of good quality but due to limited quantities and concerns of dredging river pollution or ecosystem destruction, Has been attracting attention.

The method of collecting such dredged soil and transporting it to a destination can roughly classified into a transportation method using a delivery pipe, a transportation method using a conveyor, and a transportation method using a dump truck.

Here, the transportation method using the conveyor is suitable for long distance transportation of the dredged soil, but there is a disadvantage that the transportation equipment and installation cost are expensive, and maintenance and repair are not easy.

Dump trucks are mostly used, but when long distance is required, they cause noise and dust during transport and are not economically advantageous. The transportation method using the delivery pipe can be divided into a transportation method using a pump and a transportation method using compressed air.

Compressed air transportation is similar to using a pipe as a transportation method using a pump, but it is higher than that of a transportation method using a pump. In addition, there is an inconvenience in that when the compressed air is used, the delivery pipe can be easily clogged when the liquid is below the liquid limit, that is, when the sand quality is more than 60%. Therefore, although the transportation method using the present pump is widely used, there are many technical problems to be solved when the dredged soil is transported over 30 km or longer.

However, there is a problem in that dredging costs are increased in the methods of installing such a dredged material. However, there is a problem in that the dredging cost is increased because the dredged soil is transported by a relay pump using a booster line and a transportation method using a siphon principle.

Specifically, since a high-performance pump is required for every station where dredged soil is transported at a long distance, that is, a place where a fluid is pressurized in the middle of transportation to secure a flow rate, the installation cost of the pump and the fuel cost to be used for the pump increase exponentially. Also, since the pressure in the delivery pipe is high, the material cost and installation cost of the discharge pipe greatly increase. The presently used delivery tube is a cast iron tube, because it is not efficient at high pressure.

In order to improve this, an invention of applying an electromagnetic field in a pipe to control flow is disclosed in Korean Patent Laid-open Nos. 10-2014-0122027, 10-2015-0106220, 10-2015-0090532, etc. .

More specifically, the present invention relates to an apparatus for improving the flow state in a pipe by applying an electromagnetic force, wherein a coil, which is called an inductor, is attached to the pipe and applies an electric current waveform to the pipe, Thereby improving the flow state in the pipe.

However, the above-mentioned inventions basically have a drawback in that it is difficult to apply a large current or apply a pulse of a higher frequency. In order to compensate for the above-mentioned circuit disadvantages, the circuit entering the device becomes more complicated and a burden of cost increase arises.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus for improving the performance of a multi-layer electromagnetic field generating module in which an electromagnetic field is applied to a tube to efficiently control the flow state in the tube.

It is to be understood that the invention is not limited to the disclosed exemplary embodiments and that various changes and modifications may be made therein without departing from the spirit and scope of the invention.

In order to achieve the objects of the present invention, an apparatus for improving the performance of a multi-layer electromagnetic field generating module according to exemplary embodiments can efficiently control a flow state in a pipe by applying an electromagnetic field to the pipe.

In the exemplary embodiments, the apparatus for improving the performance of the multi-layer electromagnetic field generating module may implement an inductor in a module form to maximize the pulse effect of the electromagnetic force through mechanical vibration, thereby improving the flow efficiency in the tube.

As described above, the apparatus for improving the performance of the multi-layer electromagnetic field generating module according to the exemplary embodiments of the present invention can directly convert the coil module into a simple mechanical movement without using an overcurrent and a corresponding protection device.

Thus, the fluid particles can be excited to make the fluid molecules excited to make the flow of the electromagnetic force of the coil more favorable.

In addition, the apparatus for improving the performance of the multi-layer electromagnetic field generating module may include all the advantages of the conventional electromagnetic field generating module.

For example, when the dredged soil is transported over a long distance, it can be transported with a relatively small pump capacity, thereby reducing transportation costs. In addition, since the present invention can be carried in an environment in which the transport pressure in the delivery pipe is relatively low, the cycle of replacing the delivery pipe becomes longer and the damage of various dredging devices due to the pressure drop can be reduced. Therefore, the overall cost of the dredged soil transportation system is reduced.

Fig. 1 is a view schematically showing the flow of dredged soil in a delivery pipe, Fig. 2 is a schematic view of a waveform according to physical properties of a fluid mixture, Fig. 3 is a schematic view Fig.

Referring to FIGS. 1 to 3, the Newtonian fluid, which is subject to viscosity in the flow in the delivery tube, becomes a dominant force on the wall of the delivery tube and a force dominated by the inertia force toward the center of the delivery tube. At this time, the flow rate develops as a function of the radius of the delivery tube.

However, dredged soil shows the behavior of a non-Newtonian fluid, not a Newtonian fluid. In this case, the yield stress to form the fluid flow together with the viscosity of the fluid is an important factor.

2 (a) and 2 (b) show waveform changes of non-Newtonian fluids in such Newtonian fluids, wherein (a) is the waveform of pure water with low viscosity, (c) is the waveform of dredged soil or mortar, (D) shows the waveform of a high-viscosity fluid such as concrete.

Due to such yield stress and viscosity, the flow velocity in the flow is different from that in Newtonian fluids. In the case of a mixture such as dredged soil, the flow velocity characteristics are shown in Fig.

On the inner surface of the delivery tube, a slip layer or a slip layer zone is generated due to the influence of viscosity, and a flow rate type similar to the rigid body behavior toward the central layer of the delivery tube is shown (Plug flow zone) .

In the case of a mixture such as dredged soil, due to the influence of inertia and viscosity, when the pressure is applied, large-mass components flow to the center of the delivery pipe, and particles of relatively small mass such as water and mud .

Due to this flow characteristic, the friction in the delivery pipe largely acts as three parts. The friction between the delivery tube and the fluid, the viscous friction in the mixed layer, and the friction between the lubricant layer and the center layer. Control of these friction can reduce the friction of the delivery tube as a whole.

Therefore, when the friction of the delivery pipe is reduced, the flow rate can be increased by decreasing the pressure drop of the fluid in the delivery pipe, and the power consumption for generating the pressure for the pressure transmission due to the increase of the flow rate due to the decrease of the pressure drop .

Accordingly, referring to FIG. 3, the present invention generates electric pulses at a period T corresponding to the actual flow rate by adjusting the period T for generating the waveform of the dredged soil as shown in FIG. 2 (c).

FIG. 4 is a view schematically showing a change in a dredged soil flow when an electromagnetic field is applied due to a conventional dredged soil transportation system. 5 is a view schematically showing a conventional dredged soil transportation system.

Referring to FIGS. 4 and 5, a dredged soil flow by a conventional dredged soil transportation system is a system in which a proper electromagnetic field is applied to an actual dredged soil flow according to a situation, and a magnetic flow as shown in the rightmost waveform of FIG. 4 is generated will be.

The conventional dredged soil transportation system includes a pump module 100, a piping module 200, a control module 300, a database 400, and a state measurement unit 500.

The piping module 200 includes a plurality of delivery pipes 205 wound around a coil 206 (see FIG. 4) for applying electromagnetic waves to the dredged material flowing therein.

4) is formed of a conductive material such as copper, and is wound in the direction of flow of the dredged material in the delivery pipe 205 in consideration of the Faraday's right-hand rule.

The delivery pipe 205 is connected to a plurality of delivery pipes 205 in consideration of long-distance transportation of the dredged product. In order to efficiently transport the dredged product, the diameter of the delivery pipe 205 is preferably 0.5 m, It is obvious that it can be changed according to the quantity and construction period.

The piping module 200 includes a piping pressure sensor unit 210 for detecting a flow velocity and a waveform of the dredged soil transported in the delivery pipe 205 and converting the flow velocity and the waveform of the detected dredged soil into a voltage signal . The pipe pressure sensor unit 210 may be a first pressure sensor 210a and a second pressure sensor 210b spaced apart from each other in the delivery pipe 205.

The pump module 100 provides the piping module 200 with transport pressure for dredging. It is preferable that the pump module 100 is provided at a predetermined interval in the piping module 200 so as to secure the flow rate by pressurizing the fluid in each section.

The pump module 100 may include a pump pressure sensor unit 110 for detecting the cycle of the pump and converting the cycle of the pump into a voltage signal.

The database 400 stores flow information on a flow velocity and a waveform according to physical properties of the dredged soil. It is preferable that the database 400 is capable of updating, adding, changing or deleting the flow information of the dredged soil stored by the user connected by wire or wireless.

The control module 300 communicates with the piping module 200, the pump module 100, and the database 400 in a wireless manner, and has a waveform corresponding to the flow waveform of the dredged soil transported in the delivery pipe 205 And applies a current to the coil 206 (see Fig. 4).

Conventional dredged soil transportation system is to control the flow by applying an electromagnetic field to a delivery pipe. The most important core technology is not merely to apply an electromagnetic field, but to transmit information such as a component of a fluid to be transported and a flow parameter (flow rate / And a control technique for allowing an appropriate electromagnetic pulse to be applied.

Specifically, the dredged soil transportation system is an apparatus for improving the flow state of a pipe by applying an electromagnetic force. A coil, which is called an inductor, is attached to the pipe and applies an electric current waveform to the pipe, Thereby improving the flow state in the pipe.

However, the dredged soil movement system basically has a drawback in that it is difficult to apply a large current or apply a pulse of a higher frequency. In order to compensate for the above-mentioned circuit disadvantages, the circuit entering the device becomes more complicated and a burden of cost increase arises.

6 to 8, when the inductor is installed around the pipe, a Lorentz force acts on the inside of the pipe to transmit the electromagnetic force to the polar fluid particles. At this time, the magnitude of the electromagnetic force can be obtained as follows.

In the equations (1) and (2), F denotes an electromagnetic force, q denotes a charge of a particle, E denotes an electric field, v denotes a particle velocity and B denotes a magnetic flux density.

At this time, the factor that plays a major role in the magnitude of the electromagnetic force is the particle velocity v. The present invention is a method and apparatus for increasing the magnitude of the electromagnetic force delivered to a particle by increasing the velocity v of the fluid by mechanically varying the velocity of the inducer through a link connected to the motor drive.

At this time, by using a motor control device or the like, the speed of the motor can be changed and the rotational angular velocity can be controlled to arbitrarily create a desired flow velocity waveform to increase the acceleration in a specific direction. By increasing or decreasing the flow rate in such a specific direction, the flow efficiency can be greatly improved and it can be prevented by suitably suppressing the flow rate of the fluid in the material separation state that may occur when the flow rate of the fluid is increased.

The device of the present invention has a point of connecting the link portion 2 to the conventional inductor 1 and converting the rotational motion to the translational motion through the motor driving portion 3. At this time, the motor RPM control controls the speed of the translational motion, and it can be controlled by changing the rotational angular speed of the motor. For example, the inductor 1 can be fitted into the pipe and can slide along the pipe.

As shown in FIG. 7, in the electromagnetic force pulse generated by the conventional electromagnetic field generating module, the pulse shape of the electromagnetic force generated inside can be changed by controlling the translation speed of the inductor module. The fluid in the pipe receives the excitation force and can perform additional excitation according to the flow direction.

The apparatus for improving the performance of the multi-layer electromagnetic field generating module according to the exemplary embodiments of the present invention can directly convert the coil module into a simple mechanical movement without using an excessive current and a corresponding protection device.

Thus, the fluid particles can be excited to make the fluid molecules excited to make the flow of the electromagnetic force of the coil more favorable.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be understood.
