Description

  The present invention relates to a magnetic disk drive device in a magnetic separation device, and in particular, is fixed so as to project from a peripheral surface of a magnetic disk in which driven transmission gears meshing with a drive pinion are arranged at regular intervals on a main shaft. The present invention relates to a magnetic disk drive device in a magnetic separation device that is miniaturized.

  Conventionally, in order to remove pollutants present in treated water such as ballast water and factory effluent, flocculant and magnetic powder are added to the treated water and agglomerated to make the polluted substances magnetic and form magnetic flocs. Each of the magnetic flocs generated by the aggregating apparatus is rotated by rotating a magnetic disk formed by arranging a large number of magnetic disk disks, each of which is formed with a plurality of magnets, at a predetermined interval. A polluted water purification system comprising a magnetic separation device B that is adsorbed on a magnetic disk disk and separated and removed is employed.

  By the way, as shown in FIGS. 4-5, in the conventional magnetic separation apparatus B, it is as a drive device which rotationally drives the magnetic disk 2 arrange | positioned rotatably in the main body casing (magnetic separation tank) of a magnetic separation apparatus. A plurality of magnetic disk disks are arranged in a skewered manner, and the main shaft 21 fixed via a key or the like is transmitted to a magnetic disk via a drive mechanism including a transmission chain C, a transmission gear G, and the like. And is driven to rotate.

When the transmission chain C is used for the drive device 4, as shown in FIG. 4, the transmission chain C and the driven sprocket wheel H2 meshing with the transmission chain are arranged outside the main body casing in order to protect them from dirty water. In this case, the main shaft 21 provided with a plurality of magnetic disk disks is supported in a cantilever manner outside the main body casing through the main body casing 1, and the driven sprocket wheel that protrudes out of the main body casing is fixed. The transmission chain C is stretched between the driven sprocket wheel and a driving sprocket wheel H1 fixed to a driving motor or the like.
For this reason, since at least one end of the main shaft 21 penetrates the tank wall of the main casing 1, the sealing material S is arranged around the main shaft 21 of the tank wall penetration portion in detail. It is necessary to prevent the leakage of sewage. Further, the water level in the main body casing (magnetic separation tank) is not particularly limited. For example, since the water level is about 150 mm above the center of the main shaft 21, the sealing mechanism around the main shaft 21 is made of If it is insufficient due to wear or the like, there is a problem that water leaks from that point.

Further, when the transmission gear G is used for the driving device, as shown in FIG. 5, the main shaft 21 having a plurality of magnetic disk disks housed in the main body casing (magnetic separation tank) has both ends thereof in the main body casing side wall. In this case, the above-described problem of water leakage can be prevented. However, the spindles 21 on both the left and right outer sides of the magnetic disk disk arranged in a plurality are individually separated from the magnetic disk disk. The produced transmission gear G is fixed, and the drive pinion 3 is engaged with the transmission gear for driving.
For this reason, since a plurality of magnetic disk disks and transmission gears are arranged in series on the main shaft 21 and integrated with each other, the total length of the magnetic disk becomes long, and the main body casing for storing the magnetic disk inevitably becomes large. For this reason, there is a problem that the installation space for this apparatus also increases.

  In view of the problems of the magnetic disk drive device in the magnetic separation device, the present invention provides a magnetic separation device in which the device can be reduced in size, installed in a limited space, and can solve the problem of water leakage. An object of the present invention is to provide a magnetic disk drive.

  In order to achieve the above object, the magnetic disk drive device in the magnetic separation device of the present invention comprises a plurality of magnetic flocs produced by adding and stirring a flocculant, magnetic powder and polymer flocculant to the treated water. In a magnetic separation apparatus in which a plurality of magnetic disk disks are arranged and attracted, separated and recovered by a rotating magnetic disk, the outermost magnet among the plurality of magnetic disk disks fixedly arranged on the spindle at regular intervals A driven transmission gear is formed on the outer peripheral surface of the disk board so as to mesh with the drive pinion.

  In this case, the driven transmission gear can be formed in a ring shape and fixed along the outer peripheral surface of the magnetic disk disk so as to mesh with the drive pinion.

  Further, the drive shaft to which the drive pinion is fixed can be rotatably supported by penetrating at a position above the water level in the main casing.

  According to the magnetic disk drive device of the magnetic separation device of the present invention, a magnetic floc generated by adding and stirring the flocculant, magnetic powder, and polymer flocculant to the treated water, Outer surface of outermost magnetic disk disk among a plurality of magnetic disk disks arranged and fixed at regular intervals on the main shaft in a magnetic separation device that is arranged to be attracted, separated and collected by a rotating magnetic disk In addition, by forming a driven transmission gear that meshes with the drive pinion, the total length of the magnetic disk fixed to the main shaft does not become long, so that the main casing for housing the magnetic disk can be reduced in size.

  Also, by forming the driven transmission gear in a ring shape and fixing it along the outer peripheral surface of the magnetic disk disk so as to mesh with the drive pinion, the driving force of the drive pinion can be directly transmitted to the magnetic disk, The slip can be prevented.

  Moreover, the problem of water leakage can be solved even with a simple sealing mechanism by supporting the drive shaft fixed with the drive pinion so as to pass through and rotate at a position above the water level in the main body casing.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a magnetic disk drive device in a magnetic separation device of the present invention will be described below with reference to the drawings.

  1 to 2 show an embodiment of a magnetic disk drive in the magnetic separation device of the present invention.

  A polluted water purification system for separating and removing magnetic substances from pollutants present in treated water such as ballast water and factory wastewater as magnetic flocs is composed of an aggregating device A and a magnetic separating device B.

  This agglomeration apparatus A comprises a plurality of stages of slow agitation tanks A1, A2, A3 arranged in series, and each of the slow agitation tanks A1, A2, A3 is treated with a flocculant and magnetic powder added thereto. Stirring blades Bl that rotate slowly so as to stir water at a slow speed to magnetize the pollutants and generate magnetic flocs are provided, and the magnetic separator B is located in the main casing (magnetic separation tank). A magnetic disk disk 22 having a large number of magnets arranged thereon is arranged on a rotatable main shaft 21 at a predetermined interval to form a magnetic disk 2, and by rotating the magnetic disk 2, the slow stirring in the previous step is performed. The magnetic flocs formed in the tanks A1, A2, A3 are configured to be attracted to each magnetic disk board 22 and removed.

  In addition, as shown in FIG. 1, the magnetic separation device B supports a magnetic disk 2 in which a plurality of magnetic disk disks 22 are arranged on a main shaft 21 at fixed intervals and fixed in a main casing 1 to be rotatable. . This is supported at both ends of the main shaft 21 by bearings 23 attached to the inner surface of the tank wall of the main casing 1. In this case, the whole main shaft 21 and a part of the magnetic disk 2 are excluded, and the main shaft 21 is immersed in the treated water supplied into the main body casing 1 so that the magnetic flocs in the treated water are efficiently adsorbed.

  The magnetic separator B includes a treated water supply port including a magnetic floc, a scraping trough inserted between the magnetic disk disks of the magnetic disk to collect the magnetic floc, a treated water drain port, and the like. Is disposed.

A driven transmission gear 24 is formed on the outer peripheral surface of the magnetic disk disk 22 corresponding to the outermost side of the magnetic disk 2 formed by arranging and fixing the magnetic disk disks 22 on the main shaft 21 at regular intervals.
The driven transmission gear 24 is ring-shaped and is disposed along the outer peripheral surface of the magnetic disk disk 22 or as shown in FIG. 1 so as to protrude from the outer peripheral surface of the magnetic disk disk 22. The driven transmission gear 24 is fixed to the magnetic disk board 22 with fixing tools such as bolts, scissors and keys so as to be integrated.

In this case, the driven transmission gear 24 is disposed along the outer peripheral surface of the magnetic disk board 22, but its position is not particularly limited, and is disposed at a position above the water level of the main casing 1. The drive pinion 3 is engaged and driven.
By setting the outer diameter of the transmission gear 24 to be the same as or smaller than the outer diameter of the magnetic disk board 22, the size of the magnetic separation device B can be reduced and made compact.

  As shown in FIGS. 1 to 2, the drive pinion 3 is fixed to a drive shaft 31 that is rotatably supported by penetrating at a position above the water level in the main casing. Thereby, since support parts, such as the bearing 23 of the drive shaft 31, are always in a position above the water level, the problem of water leakage can be solved without employing a special sealing mechanism.

  Since the entire width of the magnetic disk 2 fixed to the main shaft 21 is substantially the same as that before the driven transmission gear 24 is attached, the entire width of the magnetic disk 2 can be reduced. The casing 1 can also be designed small.

  The arrangement of the drive shaft 31, the drive pinion 3, and the transmission gear 24 of the magnetic disk drive device in this magnetic separation device is not particularly limited. For example, as shown in FIG. A plurality of (four) drive pinions 3 are arranged on the drive shaft 31 so that the main shaft 21 of the two series of magnetic disks 2 is driven at both ends via the same number of transmission gears 24, or FIG. ), A plurality (two) of drive pinions 3 are arranged on the drive shaft 31 so that the main shaft 21 of the two series of magnetic disks 2 is driven at one end via the same number of transmission gears 24. Further, as shown in FIG. 3C, one drive pinion 3 is disposed on the drive shaft 31, and the main shaft 21 of one series of magnetic disks 2 is connected at one end via the same number of transmission gears 24. It can be driven.

Next, the operation of the magnetic disk drive in this magnetic separation apparatus will be described.
When the drive shaft 31 is driven by a drive device (not shown), the drive pinion 3 fixed to the drive shaft 31 is also driven. Since the drive pinion 3 meshes with a driven transmission gear 24 formed on the outer peripheral surface of the magnetic disk 2, the magnetic disk 2 is also driven by the drive pinion 3 via the driven transmission gear 24. The

  In this case, since the driven transmission gear 24 is formed on the outer peripheral surface of the magnetic disk board 22, the magnetic disk and the individual gear are not used as in the prior art, so the width of the magnetic disk can be kept small. The size of the casing can be reduced, and the casing can be driven strongly in the same manner as when individual gears are used.

  Further, since the drive shaft 31 is supported on the main body casing 1 via the bearing 23 at a position above the water level, the problem of water leakage can be solved even if the sealing mechanism is simplified.

  The magnetic disk drive device in the magnetic separation device of the present invention has been described above based on the embodiments thereof. However, the present invention is not limited to the configurations described in the above embodiments, and does not depart from the spirit thereof. The configuration can be changed as appropriate.

  The magnetic disk drive device in the magnetic separation device of the present invention has characteristics that the device can be downsized and installed in a limited space, and that the problem of water leakage can be solved. It can be used widely and suitably for applications such as a polluted water purification system for separating and removing pollutants present in treated water such as factory effluent.
