Magnetic filter device

Abstract

The present invention provides a magnetic filter device designed so that a magnetic substance, which has been separated by adsorption from a liquid to be treated and trapped by a magnetic separation operation, can be extracted out from within a flow channel in a simple structure, in a very easy and effective manner. With the use of a treatment vessel 12 provided with inlet / outlet ports 26, 28 forthe liquid to be treated and a discharge port 36 for the magnetic substance separated from the liquid to be treated, the magnetic substance separated from the liquid to be treated is adsorbed to an inner peripheral surface of the treatment vessel 12 by a magnet device 20 mounted on the outer periphery of the treatment vessel 12, and eliminating the effect of a magnetic field created by this magnetdevice 20 causes the adsorbed magnetic substance to flow, due to gravity, through a communication channel 15 into a detachable collection vessel 14 positioned in the lower part of the treatment vessel 12.

Description

technical field [0001] The present invention relates to a magnetic filter device, and in particular to an improved structure of a magnetic filter device for adsorbing and separating a magnetic material such as a ferromagnetic powder or grain from a liquid to be treated in which a magnetic material such as ferromagnetic powder or grain is mixed. . Background technique [0002] Conventionally, devices and devices with a structure in which fluids such as lubricating oil and working oil circulate inside, such as engines, transmissions, and various hydraulic systems, have been used in various applications. However, in these devices and devices During use, the surface of the metal member is gradually worn, and therefore, the metal powder particles generated by the wear of the surface of the metal member are inevitably mixed into the liquid circulating inside to form a suspension. In addition, the metal particles in the liquid further promote the abrasion of the surface of the met...

Problems solved by technology

[0008] However, in order to capture and discharge the ferromagnetic particles present in the flow path from the flow path by such a magnet arranged outside the flow path, it is necessary to have a magnetic field between the flow path through which the liquid to be treated flows. In addition, if the discharge flow path is provided separately, the structure becomes more complicated. Not only that, but the amount of liquid to be treated that can fully flow out the ferromagnetic particles captured in the path increases. In the treatment of the liquid to be treated that is discharged together with the body, many problems are caused. In addition, there is also the following problem inherently, that is, when the discharge of the above-mentioned captured ferromagnetic particles becomes insufficient, the magnetic The processed liquid that has been treated by magnetic separation out of the filter device is mixed with the ferromagnetic powder and granules existing in the flow path, which reduces the purification efficiency and even the filtration efficiency of the processed liquid, etc. Therefore, in the magnetic filter device In terms of cleaning operability and even cleaning operability, it is not yet sufficient
