BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a magnetic adsorption transfer means capable of separating and transferring sludge made of fine iron powder or the like from a liquid or a pool, and is rotatably arranged on the outer surface of a magnet pipe containing a magnet. The present invention relates to a magnet pipe conveyor in which a coil and a magnet rod in the pipe in which magnets are magnetized in a spiral shape are synchronously rotated and can be conveyed by the coil.

2. Description of the Related Art A screw conveyor has been put to practical use as a device for mechanically conveying magnetic material powder such as iron chips and iron powder generated in various grinding and cutting processes such as machine tools in a dry state. However, the screw conveyor cannot transport the liquid from the liquid or when the inclination is steep.

Therefore, a magnet conveyor having various structures for attracting and conveying by using magnetic force has been put into practical use. There are various sizes and shapes of iron chips and iron powder to be transported, and they are not too small and not too large due to the balance of magnetic force and gravity when they slide on the surface of a non-magnetic material by magnetic attraction. Due to the size and shape, it was not possible to remove the sludge of fine iron powder such as the paste that was kneaded by wet.

That is, in order to remove sludge such as paste with a wet method, the surface of the magnet body is directly immersed in the liquid or magnetically adsorbed on a magnet body provided with a non-magnetic exterior material to separate the magnet body from the liquid. It was common to take out more and scrape the adsorbed sludge.

[Problems to be Solved by the Invention]

As described above, since the sludge-like material has a larger attracting force on the conveying surface of the magnet conveyor than the pulling force, it does not move from the attracting place and cannot be conveyed by the conventional magnet conveyor. It is well known empirically.

The present invention is intended to provide a magnet conveyer capable of mechanically pushing up sludge in a magnetically adsorbed state, and can be used in any place from handy to large size with an extremely simple structure. The purpose is to provide a magnet conveyor.

DISCLOSURE OF THE INVENTION As a result of various investigations by the inventors for the purpose of mechanically pushing up and transporting sludge in a magnetically attracted state, as a result, it has been found that a magnet rod spirally magnetized or magnet pieces are adhered. A non-magnetic outer cylinder such as a stainless steel pipe is covered with a rotatable minimum clearance, and a transfer coil with a minimum clearance that can be rotated by using the outer cylinder as a guide is provided. It is possible to achieve the object by adjusting the winding pitch of the use coil and further adjusting the phase so that there is a magnetized place about 3 to 5 mm above the transfer coil and rotating the magnet rod and the transfer coil synchronously. They found out and completed this invention.

That is, according to the present invention, a magnet rod having magnets spirally arranged on the outer surface is rotatably held in an outer cylinder made of a non-magnetic material, and a coil for transportation is rotatably wound on the surface of the outer cylinder. The magnet pipe conveyor is characterized in that it is arranged in a spiral manner and the spiral pitch of the magnet and the winding pitch of the coil are the same so that both can be rotated synchronously.

Further, according to the present invention, in the above structure, the magnet rod incorporated in the closed outer cylinder and the coil wound around the outer cylinder surface are held by the shaft support provided on the other end of the outer cylinder. The shaft supporting portion has a motor or a coupling with a motor as a drive source, and further, the closed head side of the outer cylinder is the transport start end and the shaft supporting portion side is the end, and the rotary drive source is the same for the shaft supporting portion. It is possible to employ a configuration in which a rotating brush that comes into contact with the coil surface at the terminal position is attached.

In the present invention, the magnet rod has a structure of a magnet body in which a plurality of rectangular or rod-shaped small magnets are spirally arranged and attached to the surface of a cylindrical or columnar body, or a cylindrical or cylindrical magnetic body. A so-called rod-shaped magnet body in which the outer surface is spirally magnetized at a required pitch can be appropriately adopted. Also,
As the magnet to be used, a bond magnet or a sintered magnet having any known composition such as a ferrite type or a rare earth type can be adopted.

Since the coil made of a triangular rectangular wire has excellent carrying capacity, it can be appropriately selected according to the object to be carried, the application, and the like.

In the present invention, the spiral pitch of the magnet or magnetic pole arrangement of the magnet rod and the winding pitch of the carrying coil must be made to face each other at the same pitch inside and outside through the outer cylinder, and both pitches are to be matched. If it shifts, the sludge cannot be transported at all.

Further, according to the present invention, the drive mechanism for synchronously rotating the magnet rod and the transfer coil includes a magnet rod housed in a closed outer cylinder and a coil wound around the surface of the outer cylinder.

The drive source can be an electric motor, a hydraulic motor, or the like that is individually attached via a speed reducer, and a configuration in which a coupling or a gear mechanism supplies from another drive source can be adopted.

For example, in order to separate and collect the sludge from the conveyor after conveying the sludge from one side of the outer cylinder to the other end with the closed head side of the outer cylinder as the transport start end and the shaft support side as the end, for example, the shaft support part is used. The coil surface of the end position where sludge is conveyed by providing a rotating brush that is rotatably provided with a gear mechanism that transmits the same rotational torque through a gear to the magnet rod and the rotational drive shaft of the coil that are supported by It is possible to employ a configuration in which a rotary brush is brought into contact with the rotary brush and the sludge is mechanically scraped off by the rotary brush.

In order to separate and collect the sludge conveyed from the conveyor, it is possible to employ a structure in which the sludge is mechanically scraped off with a rotating brush or the like, or a method in which compressed air is blown.

That is, the winding end of the carrying coil 10 wound around the outer peripheral surface of the outer cylinder 2 is fixed to the annular support portion 9 a, and the fourth gear 9 is attached to the shaft 5 a of the rotary brush 5. It is meshed with the third gear 7 to be rotated.

In short, the magnet rod 3 is rotatably rotatably supported in the cylinder of the outer cylinder 2 whose base end is fixedly secured in the gearbox 1 with a predetermined clearance from the inner peripheral surface of the outer cylinder. A transfer coil 10 is axially supported in the gear box 1 so that it can be slidably rotated with a minimum clearance provided on the outer peripheral surface of the transfer coil 2.

When the magnet rod 3 is rotated by the geared motor 20 connected to the flexible coupling 3a, the first gear 4 of the flexible coupling 3a and the second gear 6 of the shaft 5a of the rotary brush 5 axially supported in parallel therewith. The fourth gear 9 is rotated via the third gear 7, and the transport coil 10 fixed to the annular support portion 9a is configured to rotate synchronously in the same speed and in the same direction.

On the other hand, the rotating brush 5 is mounted on the shaft 5a portion protruding from the gear box 1, and the tip of the brush comes into contact with the carrying coil 10 wound around the outer cylinder 2 when rotated. The gear box 1 is provided with a cover 1a so as not to scatter the scraped sludge.

Here, it was confirmed that if the pitch, phase, and rotation do not match, sludge cannot be transported due to falling of sludge and reciprocation of the sludge during magnetizing of the magnet rod, or that transport efficiency becomes poor. Further, since the sludge has a strong adsorptivity on the conveying surface, it is necessary to rotate the sludge at a required speed so as not to rotate too fast.

In the configuration of FIG. 1, the electric motor is attached to the gear box 1 for in-line arrangement.
