る。2. Description of the Related Art Conventionally, electromagnetic filters have been used in wastewater treatment, reprocessing of used oil, and the like in steelworks. In the magnetic force selection by this electromagnetic filter, a large number of magnetic spheres such as iron balls are filled inside the tubular body, while this magnetic sphere is magnetized by an exciting coil wound outside the tubular body, Inclusions contained in the supplied wastewater and other raw material liquids to be treated are adsorbed and removed by magnetized iron balls. However, if this treatment continues for a predetermined time, inclusions adhere to the iron balls in an amount more than the permissible amount, making them unusable. For this reason, at this time, the supply of the raw material liquid to be treated from the upper part is stopped, and instead, fresh water is supplied from the upper part to eliminate the raw material liquid, then the excitation of the exciting coil is stopped, and then the inner cylinder Magnetic force is selected by supplying washing water from the lower part of the above, washing the iron ball to remove the adhering inclusions and removing from the upper part, and repeating this process.

る。First, FIGS. 3 and 4 are explanatory views of a flow chart of a cleaning water supply system of an electromagnetic filter according to a conventional example and its electromagnetic filter. The electromagnetic filter indicated by reference numeral 1 is stainless steel or the like. An exciting coil 3 is wound around a cylindrical body 2 made of a non-magnetic material, and a large number of magnetic spheres 4, for example, iron balls 4 are arranged inside thereof. Therefore, when the coil 3 is excited during the liquid treatment, the magnetic spheres 4 inside are magnetized and the inclusions in the raw material liquid to be treated are magnetically attached and removed. That is, as shown in FIG. 3, the raw material liquid supply pipe 5 and the inclusion discharge pipe 6 are connected to the upper end of the cylindrical body 2 of the electromagnetic filter 1, and the raw material liquid from which the inclusions are removed is discharged to the lower end. The raw material liquid discharge pipe 7 is connected to the raw material liquid, and the raw material liquid supplied from the supply pipe 5 is continuously treated by removing inclusions magnetically attached to the magnetic spheres 4. When this magnetizing treatment continues for a predetermined time and the inclusions on the magnetic spheres 4 exceed the allowable limit, it is necessary to clean the magnetic spheres 4, but in order to supply this cleaning water, the lower end of the electromagnetic filter 1 is cleaned. In addition to connecting the water supply pipe 81, a residual water discharge pipe 82 and a residual liquid discharge pipe 83 are connected.

われる。Therefore, when the magnetic spheres 4 cannot be used due to the inclusion of inclusions, the supply of the raw material liquid from the upper portion of the electromagnetic filter 1 is stopped. Then, by supplying fresh water from above, the raw material liquid remaining in the tubular body 2 is discharged to the outside from the discharge pipe, and subsequently, the excitation of the exciting coil 3 is stopped, and then the cleaning water is directed upward from the supply pipe 81. It is supplied and this process is repeated to perform cleaning, that is, backwashing.
【０００９】しかしながら、このように上向きの洗浄水

逆洗することによって剥離除去することはできない。[0009] However, in the electromagnetic filter having such a structure that the backwash is performed with the upward washing water,
It is impossible to supply the cleaning water over the entire tubular body 2. In particular, when the raw material liquid to be treated contains sticky substances such as fats and oils and sludge, the sticky substances adhere to the magnetic spheres, and the sticky substances are washed back upward with washing water. Therefore, it cannot be removed by peeling.

The magnetic sphere 12 is magnetized from the outer periphery of the cylindrical body 11 by a coil (this coil is not shown in FIG. 1), but a cleaning nozzle 13 is provided in the filling layer of the magnetic sphere 12 to perform the cleaning. The ejection port 131 of the nozzle 13 is made to face the magnetic sphere 12 of the filling layer.

広い範囲まで撹拌力が及ぶことになる。That is, in the electromagnetic filter 1 according to the conventional example, as shown in FIGS. 3 and 4, the cleaning water is supplied from the lower portion of the tubular body 2 as backwash water, whereas the electromagnetic filter 1 according to the present invention. As shown in FIG. 3, the electromagnetic filter 10 has a cleaning nozzle 13 provided inside a tubular body 11, and a cleaning water 14
Is sent downward from the upper part, and the cleaning water 14 is ejected from the spout 13
Then, it is jetted toward the magnetic spheres 12 with a high pressure via 1 through the magnetic spheres. When the washing water 14 is ejected in this manner, inclusions containing viscous substances such as oil and fat are separated from the surface of the magnetic spheres 12 by the impact action and stirring action of the high-pressure jet of washing water, and the inclusions are reliably removed. it can. More specifically, when the cleaning water 14 is supplied from the ejection port 131, the cleaning water can cover the entire inside of the cylindrical body 11, and therefore, inclusions can be reliably removed. Further, since the wash water is jetted at a high pressure, the adhering oil and fat is separated from the surface of the magnetic sphere by the stirring action of this high-pressure jet flow. Further, even if a part of the high-pressure jet flow is blocked by the magnetic spheres, the jet flow is reflected or wraps around and the stirring force reaches a considerably wide range.

介在物が除去できる。Further, the reaching range of the stirring force depends on the arrangement of the cleaning nozzle and its jet outlet. In this respect, if the spheres inside the tubular body are configured to rotate together, the stirring volume per spout increases, and the number of spouts can be reduced. Also, whether the jet pressure of washing water is sufficiently increased,
Inclusions can be effectively removed by giving a pulsation to the jet pressure to rock the sphere.

A branch nozzle 132 is attached from the nozzle 13 in the radial direction, and the jet nozzle 131 is attached to each branch nozzle 132 in an upward direction.

除去される。As described in detail above, since the electromagnetic filter according to the present invention is constructed as described above, the inclusions magnetically attached to the magnetic spheres can be removed very effectively. The maintenance load for prevention of deterioration of removal ability and cleaning of magnetic spheres can be greatly reduced. In particular, at the time of this maintenance, the washing water is jetted toward the magnetic spheres with a high pressure, so that the magnetic spheres collide with each other and agitate, and the inclusions are sticky and can be quickly separated and removed.
