BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental molten wax adsorption device.

[0002]

2. Description of the Related Art In producing a denture, the shape of the oral cavity is sampled with an impression material to form a female mold, and gypsum is poured into the female mold to form a plaster model having the same shape as the oral cavity. Next, this is attached to an articulator that can move like a human jaw, and artificial teeth are arranged using wax on a plaster model.

Thereafter, the plaster model was removed from the articulator, and the plaster model was first buried in a dividable metal frame (flask) so that the lower part of the plaster model was buried. Then, the plaster model was buried. After the plaster is hardened, a separating material is applied to the plaster, and secondary burial is performed so that the upper portion of the plaster model is burial on the plaster.

After the secondary burial has set, the flask is immersed in hot water for a few minutes and the flask is divided between the primary and secondary burial to remove the softened wax. The wax that cannot be completely removed at this point is dissolved and removed later by sprinkling hot water.

Finally, a resin is injected into the portion containing the wax, the resin is cured and then removed, and the denture is obtained by adjusting the polishing.

The above-mentioned melted wax is introduced into a cooling tank together with hot water, and after cooling, it is solidified and scooped up in a state of floating on the water surface for disposal.

[0007]

However, the molten wax brought into the cooling tank together with the hot water sometimes overflows from the cooling tank and flows into the drain pipe. Further, since the work of scooping up the solidified wax floating on the water surface of the cooling tank is troublesome, the work is often carried out roughly, and the amount of wax flowing into the drain pipe is relatively large.

Further, there is a case where the molten wax is directly flown to the drain pipe together with the hot water without using the cooling tank because the above-mentioned work is troublesome.

The molten wax that has flowed into the drainage pipe is cooled after it has flowed into it, and adheres to the inner wall of the drainage pipe, gradually causing clogging.
The removal work is extremely difficult.

SUMMARY OF THE INVENTION In view of the above situation, it is an object of the present invention to solve the above-mentioned problems and to provide a dental dissolved wax adsorbing device capable of removing the dissolved wax extremely easily and reliably.

[0011]

According to the present invention, the above object is achieved by having an adsorbent in which a mat member made of polypropylene and having porous fibers is formed in a container shape having an opening at the top. It

[0012]

In the present invention having such a construction, the hot water used for removing the wax in the female mold of the plaster is poured into the container-shaped adsorbent together with the molten wax.

The adsorbent is made of a mat material made of polypropylene and made of porous fibers, and adsorbs the melted wax. On the other hand, the fiber has water permeability, but does not have water absorption. Therefore, only the melted wax is adsorbed, and the hot water permeates the adsorbent and is drained. The molten wax is adsorbed by the adsorbent, cooled, and solidified.

After adsorbing a predetermined amount of wax, the adsorbent is removed from the apparatus and then disposed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a partially cutaway perspective view of the apparatus of this embodiment. In the figure, reference numeral 1 is an adsorbent in which a mat material made of polypropylene and made of porous fibers is sewn into a container shape, and the upper portion is opened.

The matte material of the polypropylene porous fiber is used as an oil adsorbent for removing oil in oil spill accidents such as ships or oil in oil-containing wastewater. In this example, an oil adsorbent “Orthove” (registered trademark of Unicel Co., Ltd.) manufactured by Unicel Co., Ltd. was used as a material for the adsorbent 1.

The adsorbent 1 is made by cutting a mat material to an appropriate size and then joining the mat materials. The joint portion 2 projects inward and is formed into a container shape, for example, by sewing. . In order to increase the contact area with the hot water containing the melted wax that is poured, that is, the adsorption capacity of the wax, it is desirable that the above-mentioned joining portion 2 overhangs at many points and is wide.

The adsorbent 1 is housed in a cage-like support frame 3 for reinforcement so that the hot water containing the molten wax does not lose its shape when poured into the upper opening. The shape of the support frame 3 is not limited, and it is sufficient if the support frame 3 maintains a constant shape and has water permeability.

In the apparatus of this embodiment, the hot water containing the melted wax is poured into the adsorbent 1 from above in FIG. The adsorbent 1 does not have water absorption, adsorbs only the dissolved wax, and the hot water is permeated and drained toward the outside as shown by an arrow Q. The molten wax adsorbed on the adsorbent 1 is cooled and solidifies as it is when the hot water is drained. Such adsorption is repeated, and when the adsorption capacity of the adsorbent 1 decreases, the adsorbent 1 is removed from the support frame 3 and discarded. Then, a new adsorbent is set.

According to the apparatus of this embodiment, even if the hot water is almost completely filled in the adsorbent 1, the liquid level immediately drops due to the permeated drainage of the hot water, so that the melting is performed as in the conventional cooling tank. The wax does not spill with the hot water. Further, the hot water containing the melted wax can be successively added to the adsorbent 1 within the range of the same flow rate as the drainage amount.

The adsorbent of the present invention does not have to have a rectangular parallelepiped shape as shown in this embodiment, and the point is that it should have a container shape having an opening. In addition, the support frame is not essential in the device of the present invention as long as the adsorbent can sufficiently maintain its shape depending on its shape.

[0023]

As described above, according to the present invention, only the melted wax is adsorbed and the hot water permeates and drains by the adsorbent formed in the shape of a container by the mat material composed of the porous fiber made of polypropylene as described above. Therefore, the wax can be collected easily and surely, and the drain pipe is not clogged.
