Description

[Detailed Description of the Invention] The present invention relates to an ashtray using a magnetic material, particularly a ferrite material.

Traditionally, ashtrays made of glass, ceramic, and metal have been frequently used.

Depending on where it is used, for example, ashtrays used in reception rooms are considered to be ornaments, similar to ornaments.

However, in the past, only the unique characteristics of materials such as glass, ceramics, and metals were utilized for their decorative effects, such as weight, luster, and design. Little consideration has been given to the use of ashtrays in the function of ashtrays.

The object of the present invention is to provide an ashtray that effectively utilizes the characteristics of magnetic materials such as iron, especially ferrite.

Ferrite can be obtained as a by-product of heavy metal treatment in wastewater, and is generally said to be an oxide magnetic material with much higher electrical resistance than metal magnetic materials.

Conventionally, ferrite has attracted attention for this property and has been used mainly as an electrical component, but the characteristics of ferrite are not limited to its use as an electrical component, and can be utilized in various products.

Ferrite is obtained as a by-product of heavy metal treatment of wastewater through the following two processes.

In other words, divalent iron ions Fe+2 are present in the waste liquid containing heavy metals.
When and divalent metal ion M+2 other than iron coexist,
When an equivalent amount of alkali is added to this, a mixed hydroxide is obtained by the following reaction.

xM+2+(3-X)Fe+2+60H-→MxF'e
When a mixed hydroxide of 3-x(OH) is oxidized under specific conditions in an aqueous solution, it undergoes the process of redissolution and complex formation, and finally produces a black spinel compound (ferrite) rawhide through the reaction of the following formula. be done.

MxFe3-x(OH)6+02→MXFe3-x04
Through the above process, the metal ions M'' are incorporated into the crystal lattice of ferrite and become an insoluble solid (ferrite), which can be easily separated and extracted from an aqueous solution by magnetic separation or the like.

The by-product ferrite obtained as a powder by the above treatment can be molded into any shape by molding or the like.

For example, this by-product ferrite powder is granulated, mixed with resin or cement as a binder, and molded and solidified, or the powder is mixed with resin and molded, then sintered at a high temperature (for example, 1ioo°C) to form the powder shown in Figure 1. The ashtray body 1 shown in FIG.

Although the shape of the container 1 is not particularly limited, an annular seat 3 is provided on the opening edge of the container 1, and a recess 4 of a shape suitable for placing a cigarette is provided on the upper surface of the cigarette holder 2, and a recess 4 on the lower surface. A seat portion 5 that fits the annular seat 3 is formed.

This cigarette receptacle 2 is made entirely or partially of a permanent magnet.

When using the ashtray of the present invention, as shown in Fig. 2, the cigarette receptacle 2 is magnetically attracted to the container 1 and fixed at any position on the annular seat 3, and the container 1 is placed on a tabletop or the like. It is used as follows.

As described above, the present invention uses ferrite as the molding material for the ashtray, and furthermore, the ashtray is composed of a container body and a cigarette holder, so that it has the following effects.

That is, (1) ferrite has high heat resistance and will not be damaged even if a large amount of cigarette butts burns in the ashtray like a glass ashtray.

(2) Since the specific gravity of ferrite (4.60 g/C4) is smaller than the specific gravity of iron (7.87), an ashtray that is lightweight and has a bulky appearance can be obtained.

(3) Excellent corrosion resistance and water resistance, no rusting, and no deterioration even after long-term use.

(4) By combining the container body and the cigarette holder, it is possible to attach a cigarette holder that is longer than the width of the annular seat provided at the opening edge of the container body at a desired position, stably holding cigarettes, and When not in use, the cigarette holder can be removed and stored compactly.

Additionally, the ashtray is easy to clean.

(5) Ferrite obtained as a by-product of heavy metal treatment can be effectively utilized.

In this embodiment, ferrite material was particularly described, but it can be seen that the same effect can be achieved even if the container body 1 is made of iron.

However, iron vessels have problems such as corrosion.
