1 to 4 , the iron removal device 100 having a magnetic force magnitude measurement function according to the present invention includes a body part 110 , a raw material supply part 120 , a coil part 130 , a filter part 140 , It includes a magnetic force detecting unit 150 and a measuring unit 160, and before packaging a liquid raw material such as a secondary battery raw material, the magnetic force is measured in the process of removing the fine metal powder of the iron component contained in the liquid raw material as electromagnetic force. It relates to a device for

In this case, although it has been exemplified as removing the metal powder from the liquid raw material, it is not limited thereto, and powder raw materials and the like can be applied.

As shown in FIGS. 1 and 3 , the main body 110 includes a raw material supply unit 120 , a coil unit 130 , a filter unit 140 , and a magnetic force detection unit 150 . In this case, the main body 110 may be provided with movable wheels at the lower portion.

The raw material supply unit 120 reversely moves the liquid raw material from the lower side to the upper side of the main body part 110 as shown in FIGS. 1 and 3 , so that the residence time of the liquid raw material is increased, so that the metal powder contained in the liquid raw material the removal rate is improved.

At this time, the raw material supply unit 120 is provided with a raw material inlet pipe 122 through which a liquid raw material is introduced in the transverse direction, and a raw material supply connection pipe extending to the upper side of the main body 110 in a direction orthogonal to the raw material inlet pipe 122 . 124 is provided, and the raw material discharge pipe 126 is provided at the upper end of the raw material supply connection pipe 124 in the transverse direction.

And a pump is installed in the raw material inlet pipe 122 to forcibly transfer the liquid raw material to the raw material supply connection pipe 124 .

Further, at the ends of the raw material inlet pipe 122 and the raw material outlet pipe 126, a raw material supply valve 122a and a raw material discharge valve 126a for opening and closing the raw material inlet pipe 122 and the raw material outlet pipe 126 are provided, respectively. .

And the stopper 124a detachable by the fastener is installed on the opened upper part of the raw material supply connection pipe 124, and the upper part of the magnetic force detection part 150 is fixed to the bottom surface.

As shown in FIGS. 1 to 3 , the coil unit 130 is disposed to face the raw material supply connector 124 , and generates electromagnetic force inside the raw material supply connector 124 . That is, the coil unit 130 is configured to generate electromagnetic force using an electromagnetic coil and includes a plurality of coils (solenoid coils) wound around the raw material supply connector 124 .

Here, the coil unit 130 is formed as a known electromagnet that generates a predetermined Gaussian magnetic field by applying power from a power supply unit (not shown in the drawing), and thus a detailed description thereof will be omitted.

As shown in FIGS. 1 to 3 , the filter unit 140 is detachably located at the lower portion of the raw material supply connection pipe 124 so as to pass through the supplied liquid raw material and electromagnetic force generated from the coil unit 130 . It is provided in the form of a mesh to filter the fine metal powder in the liquid raw material.

That is, when the filter unit 140 passes the liquid raw material through the filtering holes (not shown in the drawing) of the filtering member while receiving the electromagnetic force by the coil unit 130 , the metal powder contained in the sieve raw material By being attached, it becomes possible to filter the metal powder of iron component from the liquid raw material.

At this time, the multi-stage filtering member constituting the filter unit 140 is supported under the magnetic force detection unit 150, and by maximizing the contact area to the liquid raw material, it is possible to effectively filter the fine metal powder contained in the liquid raw material.

Accordingly, the multi-stage filtering member receives the electromagnetic force provided from the coil unit 130 and filters the metal powder contained in the liquid raw material as electromagnetic force.

As shown in FIGS. 1 to 4, the lower end of the magnetic force detection unit 150 is located inside the filter unit 140 so that the magnitude of the magnetic force acting on the filter unit 140 is output differently depending on whether the liquid raw material passes or not. do.

At this time, the magnetic force detecting unit 150 is a magnetic material having an axial shape, and the multi-stage filtering member is fixed to the lower side, and the measuring unit 160 for measuring the magnetic force while the upright upper end is fixed to the lower part of the stopper 124a is electrically connected

Moreover, the magnetic force detecting unit 150 is composed of a shaft 152, and a locking protrusion 152a is formed at the lower portion so that the filter unit 140 is seated on the edge chin.

On the other hand, although not shown in the drawing, the shaft, which is a component of the magnetic force detection unit of another embodiment, has a spiral fastened to the fastening member on the upper outer circumferential surface. It can be spirally fastened by

In addition, a coupling protrusion having a shape such as a square column is provided on the upper portion of the shaft, and a rotating member is provided on the coupling protrusion. ) can be securely fastened to

As the magnetic force is concentrated on the upper surface of the magnetic force detection unit 150, the measured value (Gaussian value) is changed according to the magnetic force strength.

That is, the magnetic force detecting unit 150 has a different measurement value when there is a liquid raw material inside the filter unit 140 and when there is no liquid raw material. As the magnetic force flows more smoothly, the magnetic force is large, but when there is no liquid raw material, the magnetic force is small due to the air permittivity remaining in the filter unit 140 .

Therefore, when the liquid raw material flows inside the filter unit 140, there is a change in the magnetic force due to the metal powder contained in the liquid raw material, and the foreign substances (metal powder) removed inside the filter unit 140 during the iron removal process are removed. If it remains, the magnetic force changes, but the inside of the iron removal device cannot be checked with the naked eye, so it is possible to grasp it with the measured value.

This infers or dataizes the cleaning cycle or data of the filter unit 140 while checking whether foreign matter remains inside the filter unit 140 by a change in the magnetic force.

As shown in FIGS. 1 and 2 , the measurement unit 160 is a Gaussian meter magnetometer of a known technology that detects the magnetic force of the magnetic force detection unit 150 and outputs a result value, and a detailed description thereof will be omitted.

Moreover, the measuring unit 160 is in a state in which the electrically connected measuring probe (not shown) is in surface contact with the upper surface of the magnetic force detecting unit 150 . After detecting the magnetic force of the steel applied to the detection coil unit 130, the value is measured.

At this time, the measuring unit 160 outputs a current change by sensing the magnetic force of the steel material with a detection coil, for example. For example, the measurement unit 160 is a fluxgate sensor, and applies an AC current to the core coil, and senses that an electric signal is induced in the detection coil according to a change in the magnetic flux density of the core. At this time, when the external magnetic field is overlapped, the time at which the magnetic flux density is saturated in the induced electrical signal is different, so that the amplitude is changed, and the measurement unit 160 detects this change by the phase detector (not shown in the drawing) and detects the external An output signal corresponding to the magnetic field is obtained.

In this way, in the deironization apparatus 100 having a magnetic force magnitude measurement function according to the present invention, the liquid raw material is introduced through the raw material inlet pipe 122 at the lower side, passes through the raw material supply connection pipe 124, and then the raw material discharge pipe at the upper side ( 126), the coil unit 130 is magnetized by the power supplied from the power supply unit, and the metal powder contained in the liquid raw material that has passed through the filter unit 140 is attached to the filter unit 140, so that the liquid raw material is removed from the liquid raw material. It will filter the iron-based metal powder.

In this process, magnetic force data that is changed depending on whether foreign substances such as metal powder remain in the filter unit 140 and whether the liquid raw material is transferred by the magnetic force detection unit 150 located inside the raw material supply connection pipe 124 is detected. is obtained, and the current change is outputted from the measuring unit 160 and measured. In this way, the data obtained by the magnetic force size measurement function can be utilized according to the iron removal efficiency.
