Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transportation and supply device that can safely transport a large amount of easily oxidizable powder or granules and safely supply them at a destination. In particular, the present invention relates to a transport and supply device suitable for transporting and supplying easily oxidizable tensile powder or granules from a production site to a site of use.

Recently, magnetic recording media called so-called metal tapes have come into use, and various ferromagnetic metal powders and ferromagnetic alloy powders have been developed for use therein (for example, Tokukai No. 11 Irisho 55-3862). Publication, U.S. Patent No. L206.a
No. 68, Lu 6han No. 627, etc.).

It is manufactured using methods such as jelly.

Immediately after these ferromagnetic materials are manufactured, the powder agglomerates to form grains or lumps (hereinafter referred to as granules) with a diameter of 10 to 100 ml, which is then transported to the magneto-sensor manufacturing site and processed into a noinder. , after crosstalk dispersion treatment with solvent etc.
Magnetic recording media are manufactured by coating and drying plastic films.

This type of ferromagnetic material is highly susceptible to oxidation, and when it comes into contact with air there is a risk of oxidation and exothermic ignition, requiring cumbersome means to transport it to the magnetic tape preparation site. For example, the ferromagnetic material is sealed in a plastic film bag and transported in a can or the like, or the material is transported in a moistened state with a solvent 1 from Turkey. However, when transporting in a plastic bag, there is a chance that the pieces will oxidize when removed from the folds1, and if there is a large amount, there is a risk of fire due to heat generation1. In addition, these cans must be dismantled at the magnetic tape manufacturing site, and the bag must be torn open to release the contents while avoiding contact with the air as much as possible. When using a solvent such as toluene, a considerable amount of K is added to avoid oxidation (t5 for ferromagnetic materials).
2.0 times), and the magnetic tape manufacturing site had the disadvantage of having to use a solvent before crosstalk. Also, in the latter case, when considering the oxidation heat generation during solvent treatment and solvent removal, the unit that could be safely transported was 5-11 degrees.
