Description

[Detailed explanation of the invention] This invention places the mold on the water-flowing bottom of the mold plate, pours boiling water over it, dissolves the original wax into the water tank, and floats the wax with low specific gravity to the water surface. This relates to a wax separation and recovery device for dental technology that allows accumulated water to be discharged from the bottom of the tank to a drain pipe to easily dewax the mold without fear of wastewater contamination.
An example of its implementation is as follows.

In the figure, 1 is a water tank made of heat-resistant plastic, light alloy, or stainless steel plate, large enough to allow simultaneous dewaxing of several molds 2, and deep enough to completely separate water and wax. The water inlet a shown in FIG. 2 of the drawing is located at the bottom of the ice tank 1 on one side, and the upper end opens into the space formed in the upper part of the water tank 1 to serve as an air port. A drain pipe 3 with a water outlet C peeking out to the outside of the aquarium tank 1 is provided a little below the air opening, and this drain pipe 3 may be provided as shown in Figures 3 and 4 of the drawings as the case may be, and as described above. The air port may be omitted, or it may be provided outside the tank 1 and the water inlet 2 communicates with the lower part of the tank 1 instead of being placed inside the tank 1 as shown in the figures above. When using the water tank 1 in a sink, leave the water outlet C open as it is, and when using it on a tabletop, etc., connect the hose 4 to the water outlet C and insert the end into the sink or drain. shall be.

5 is a mold plate made of the same material as the aquarium 1 and placed on the aquarium 1;
A mold 2 molded using wax 7 as an original shape is placed on this water-flowing bottom 6, and when hot water is poured into the mold through a spout 8, the hot water and melted wax fall into the water tank 1.

An example of implementation of the wax separation and recovery device for dental technology according to the present invention is configured as described above, so when dewaxing the mold 2, the height of the water outlet C of the drain pipe 3 is After pouring the water, place the mold plate 5 on the water tank 1, place the mold 2 to be dewaxed on the water passage bottom 6, and pour hot water into the mold 2 from the pouring port 8. The wax 7, which was the prototype for the mold 2, melts and falls into the water tank 1 along with the hot water, increasing the amount of water in the water tank 1.The increased amount of water in the water tank 1 then enters the water inlet a from the bottom and drains into the drain pipe. 3 and is discharged out of the water tank 1 from the water outlet C. However, since the wax has a lower specific gravity than water and floats on the water surface, when the wax removal is finished, the mold plate 5 is removed from the water tank 1 and placed above the water surface. If you use a fine net to scoop out the wax that floats on the waste water, or drain the water with the wax floating on it into a filter, you can completely separate and recover the wax from the water, and there is no need for some wax to get mixed in with the wastewater. Therefore, even if the wastewater is directly discharged into the sewer, there is no risk of polluting the water quality of the river.

Conventionally, when dewaxing molds for dental technology, the mold was placed in a sink and poured boiling water over it to melt the wax and flush it down the drain along with the hot water, which caused the wax to flow directly into sewers and into rivers, contaminating the water quality. Not only does it cause pollution, but the wax that can be reused if collected is wasted as waste.Furthermore, using a sink to remove wax causes the wax to scatter and stain the sink and surrounding area, making it difficult to clean up afterward. there were.

On the other hand, the wax separation and recovery device for dental technology according to the present invention has a drain pipe on one side of the water tank of the required depth, with the water inlet located at the bottom of the water tank and the water outlet located at the top of the water tank. Install and launch the water outlet height, said the top of the water tank,
The mold is placed on the water-flowing bottom and boiling water is poured over it to dissolve the wax into the water tank.The mold is removably placed on top of the water-flowing bottom of the mold, so the mold is placed on the water-flowing bottom of the mold and boiling water is poured over it. For example, the melted wax comes out of the mold and falls into the water tank along with the hot water, the wax with low specific gravity floats on the water surface, and the water with high specific gravity enters the inlet of the drain pipe from the bottom of the tank, and is discharged to the outside from the outlet. Therefore, after dewaxing, if you remove the mold plate and collect the wax floating on the water surface, it is extremely easy to separate and recover the wax from the water. The wax is blocked by the saucer and does not scatter outside, and therefore does not stain the surrounding area, so by connecting a hose to the outlet of the drain pipe and placing it in a sink or drain, dewaxing work can be done even on a tabletop. And there is no hassle of cleaning up afterwards.

In particular, this device separates water and wax based on the difference in specific gravity, so the separation is reliable and no wax is mixed into the water.
Even if the wastewater is discharged into the sewage system, it will not pollute the water quality of the river, and if the wax is removed separately by type, the collected wax can be reused and waste of materials can be eliminated. It is possible.

Furthermore, this device removably places the mold plate on top of the aquarium, so if it is placed on top of the aquarium, it can be conveniently removed as described above, but if it is removed, the aquarium can be opened. It also has the effect of making it easier and more reliable to collect the wax that has accumulated in the tank and to clean the inside of the aquarium.
