Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for treating sewage produced by dental treatment, and more particularly, to more effectively suck and discharge sewage produced by dental treatment. TECHNICAL FIELD The present invention relates to a dental treatment wastewater treatment device that purifies and discharges wastewater.

[0002]

2. Description of the Related Art In dental treatment, as is well known, a saliva ejecting tube (vacuum tube) for discharging sewage in the oral cavity, a spitton for discharging gargling water in the oral cavity after treatment,
A drainage pipe or the like for draining pot washing water or the like for washing the spittoon is used.

FIG. 3 is a schematic view of a main part for explaining an example of a water distribution system in a conventional dental treatment unit. In the figure, 1 is a saliva discharge pipe, 2 is a vacuum pipe, 3 is a spittoon,
4 is a mouthwash water supply pipe, 5 is a pot-washing water supply pipe, 6 is a spittoon drainage pipe, and as is well known, the saliva discharge pipe 1 is under dental treatment,
It is put into the oral cavity of a patient, and saliva in the oral cavity, blood generated by dental treatment, other sewage, air and the like are sucked and discharged through the vacuum tube 2. In addition, during or after the dental treatment, the patient receives water ejected from the gargle water supply pipe 4 (fountain type) or water from the gargle water supply pipe 4 in a cup (cup type), Gargle and spit the gargled water into Spitton 3. As described above, the spit-on 3 soiled by gargle or the like is washed with the water supplied from the spit-on (pot) wash water supply pipe 5, and is discharged through the drain pipe 6 together with the blood and other dirt discharged along with the gargle water. .

[0004]

As described above, in the conventional dental treatment apparatus, the sewage from the saliva ejecting tube 1 is discharged through the vacuum tube 2, and the sewage from the spitton 3 is discharged through the drain tube 6. , The drainage system was multiple and it was complicated. Therefore, even if a sewage treatment device is installed in the drainage system and the sewage is made into clean water before it is discharged, more than one cleaning device is required, and the drainage system becomes more and more complicated. The drainage from Spitton was discharged to the outside of the hospital as it was, and it was very unsanitary.

[0005]

The present invention has been made to solve the problems of the prior art as described above.
(1) A single drain pipe to which all wastewater drain pipes used for dental treatment, such as a saliva drain pipe, a drain pipe for draining mouthwash water, and a pot washing water, are joined, and the single drain pipe is provided. A vacuum device and a gas-liquid separation device for separating liquid waste into a liquid that is sucked through the single drain pipe by the vacuum device, or (2) a saliva discharge pipe, gargle water, pot-washing water, etc. A plurality of dental treatment units each having a wastewater drainage pipe of a drainage pipe to be discharged are provided, all the wastewater discharge water pipes of the plurality of dental treatment units are connected to a single drainage pipe, and the single drainage pipe is vacuumed. A single vacuum device is connected to the device to suck in the sewage of the plurality of dental treatment units, and a gas-liquid separator is used to separate the gas and discharge the sewage. And further (3) in (1) or (2) above. There are guides the sewage separated by said gas-liquid separator to the sewage treatment apparatus, it is characterized in that it has to be drained in the clean water at the soil water treatment system.

[0006]

[Function] All the sewage generated by dental treatment is sucked and discharged collectively by a single vacuum device.
Eliminates the need for a separate vacuum unit for each dental unit and simplifies the drainage system to ensure wastewater treatment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram of an essential part for explaining an embodiment of a dental treatment sewage treatment apparatus according to the present invention, in which 7 is a Venturi type siphon, 8 is a solenoid valve, 9 is a solenoid valve,
Other parts of the valve, such as a manual valve, which have the same functions as those of the prior art shown in FIG. 3, are designated by the same reference numerals as in FIG. Thus, in the present invention, the vacuum pipe 2 is connected to the drain pipe 6 through, for example, the Venturi type siphon pipe 7, and the drain pipe 6 is connected to the vacuum device 20 via the gas-liquid separator 10. ing.
Therefore, in the present invention, since all the wastewater discharged from the dental unit is forcibly discharged through the single drain pipe 6, the drainage system is unified and simplified, and further,
Drains reliably. Also, even if multiple dental treatment units are installed on the same floor,
As shown by 6 ', 6 ", the drain pipes 6', 6" from other dental units which have the same function as the drain pipe 6 can also be connected to a single water distribution pipe, so that the dental treatment unit However, even if there are multiple units, the drainage system will not be complicated.

As described above, the waste water in the drain pipe 6 is sucked by the vacuum device 20, and the gas-liquid separation device 10
Where it is separated into gas and liquid. The separated polluted gas is sterilized by a germicidal lamp or the like, and the gas is deodorized and dust-removed by the filter 30 and the like and then discharged. Further, the separated contaminated liquid is discharged from the drainage port A, guided to the sewage treatment apparatus shown in FIG. 2, cleaned by the sewage treatment apparatus, and then discharged to the outside.

FIG. 2 is a diagram showing an example of a sewage treatment apparatus for collectively treating sewage discharged from the drainage port A shown in FIG. 1, in which 41 is a filter, 42 is a sewage receiving tank,
42 is a suction pump, 43 is a filter, 44 is an adsorption tank, and relatively large dust is removed from the dirty water supplied to the filter 41. The sewage from which large dust has been removed flows into the sewage water receiving tank 42, and when the water level reaches the upper limit level L ₁ , the suction pump 43 operates and stops when it reaches the lower limit level L ₂ . The sewage sucked by the suction pump 43 is supplied to the filter 44, and after removing mainly viscous substances such as blood contained in the sewage, the sewage is supplied to the ion adsorption tank (chelate resin tank) 45. Then, after removing heavy metal amalgam or the like to make clean water, the water is discharged to the outside through the drain pipe 46, or
Alternatively, as shown by the dotted line, the water is returned to the water receiving tank 42 and discharged as clean water from the outlet 47 of the water receiving tank 43.

[0010]

As described above, according to the present invention, all the dirt generated in dental treatment is finally discharged through a single drain pipe, so that the drain pipe path is simplified and the piping is simplified. Construction and maintenance are very easy. Unlike conventional natural gradient drainage, forced suction is performed, so the flow of dirty water in the pipe is smooth, and there is no problem such as clogging. Due to the forced suction, a bad odor or the like does not occur in the room, the in-hospital environment can be kept good, and moreover, it can be safely treated with a filter without touching blood and the like, which is hygienic. Since the treatment wastewater and the heavy metals contained in the treatment wastewater are surely forcibly discharged, and treated sanitarily so as to be purified water and allowed to flow into the general drainage channel, there is no fear of environmental pollution. Blood etc. discarded in the spittoon is forcibly sucked and discharged together with gargle water, pot washing water, etc., so it is hygienic without the need to touch it. By using a germicidal lamp (ultraviolet lamp), an ion adsorbent (chelate resin), a filter, etc., not only blood but also heavy metal amalgam and other things are processed and discharged as clean water, so it does not pollute the environment. It is hygienic. And so on.
