Description

TECHNICAL FIELD The present invention relates to an apparatus for sterilizing contaminated experimental materials such as laboratories, laboratories and hospitals handling viruses and bacteria. It is about.

(Prior art) Laboratory equipment in the biotechnology industry is brought in through a pass box equipped with a germicidal lamp, and when carrying out contaminants such as used laboratory equipment, all must be autoclaved. After being subjected to high-pressure steam sterilization, it is carried out of the room. Then, in order to reuse the experimental equipment, what is dried after sterilization cleaning is brought into the clean room via the pass box.

(Problems to be Solved by the Invention) The conventional sterilization equipment such as the autoclave described above uses high-pressure steam, so that the equipment becomes large-scale, and the sterilization time and the cooling time after sterilization are long. Therefore, there is a problem that running cost becomes high.

In addition, it is impossible for the experimenter to clean and sterilize the experimental equipment to be reused because it requires a lot of work such as washing and drying.Therefore, put the experimental equipment in a sealed container and pass it outside the laboratory through a pass box. It is used in the laboratory through the pass box again after cleaning and sterilization outside the laboratory. For this reason, there is a problem that it takes a lot of manpower and time to reuse the experimental equipment, and inevitably the number of the equipment also increases.

(Means for Solving Problems) In order to solve the above problems, in the present invention, a reflection plate is provided on the inner surface of a closed container having an opening / closing door, and a high frequency of a plurality of high frequency irradiation equipment is provided on the top plate part. Provide an irradiation unit,
Water injection nozzles for water injection equipment are installed on both side walls.
In addition to installing a drainage tank for drainage equipment at the bottom of the closed container,
A high-frequency heating sterilization apparatus is provided in which a contaminant mounting plate having a drainage hole is provided on the upper surface, and high-frequency heating sterilization, cleaning and drying are performed in this container.

(Operation) According to the high-frequency heat sterilization apparatus of the present invention configured as described above, high temperature sterilization can be performed in a short time by irradiating contaminants with high frequency. In this case, when the contaminant is in a dry state, it can be effectively heated by giving water to the contaminant by jetting water and irradiating it with a high frequency.

Further, it is possible to wash the inside of the apparatus by using a water jet facility, and it is also possible to dry the washed one by high frequency heating.

(Embodiment) An embodiment of the device of the present invention will be described below with reference to the drawings.
In the figure, 1 is a closed container having an opening / closing door 2 (see FIG. 2),
Reference numeral 3 is an opening / closing handle of the opening / closing door 2.

In this embodiment, as shown in FIG.
The reflection plate 4 is provided on the inner surface of the device, and a plurality of (three in the present embodiment) high-frequency irradiation units 5 of high-frequency irradiation equipment are provided on the top plate portion.
The water injection nozzle 6 of the water injection equipment is provided on both side walls, the drainage tank 7 of the drainage equipment is provided at the bottom of the closed container 1, and the top surface thereof has a drain hole (not shown) for contamination. An object mounting plate 8 is provided.

In the figure, 9 is a drain pipe connected to the drainage tank 7, 10 is a contaminant placed on the placing plate 8, 11 is a pressure sensor provided on the top plate of the closed container 1, 12 is a temperature sensor, and 13 is a temperature sensor. Is an A / D converter electrically connected to the high-frequency irradiation unit 5, the water jet nozzle 6, the pressure sensor 11, and the temperature sensor 12, respectively, 14 is a computer connected to this A / D converter 13, and 15 is this computer 14 It is an operation panel connected with.

That is, by operating the operation panel 15, the respective facilities can be electronically controlled.

Further, FIG. 3 shows an example of an apparatus for sterilizing waste water by means of the drain pipe 9 of the device shown in FIG. 1, where 16 is a water storage tank connected to the drain pipe 9, 17 is a water pump, and 18 is a drain pipe. , 19
Is a high frequency irradiation sterilizer, 20 is a temperature and pressure sensor, and 21 is a water cooling device.

Next, the operation of the device of the present invention configured as described above will be described.

In order to sterilize the contaminants 10, the opening / closing lid 2 of the closed container 1 is opened, the contaminants 10 are placed on the placing plate 8, the opening / closing door 2 is closed, and then the operation panel 15 is operated to operate the high frequency irradiation equipment. To activate
A high frequency is irradiated from the high frequency irradiation unit 5. This irradiated high frequency directly hits the contaminant 10 as shown by the dotted line in FIG. 1 or indirectly reflected by the reflector 4, so that the contaminant 10 is heated to a high temperature in a short time and sterilized.

In this case, if it is difficult to heat the contaminants 10 in a dry state, water is sprayed from the water jet nozzle 6 in advance.
Moisture should be added to 10.

Next, in order to wash the contaminants 10, the operation panel 15 is operated to operate the water injection equipment, and water is injected from the water injection nozzles 6 as shown by the solid line in FIG. Just hit it. In this case, the drainage is collected in the drainage tank 7 below the drainage hole of the contaminant mounting plate 8 and discharged to the outside through the drainage pipe 9.

In order to dry the pollutant 10 that has been washed, the high-frequency irradiation equipment is activated again to heat and dry it.

Further, the drainage discharged from the drainage pipe 9 to the outside is, for example, the third
According to the apparatus shown in the figure, it is possible to easily sterilize by heat sterilization by high frequency irradiation and treat it as general waste water.

(Effect of the invention) The high-frequency heat sterilizer of the present invention configured as described above,
In addition to being more compact than conventional devices, this also allows high temperature sterilization in a short time by irradiating contaminants with a high frequency, which reduces running costs and improves efficiency. In this case, when the contaminant is in a dry state, it can be effectively heated by giving water to the contaminant by jetting water and irradiating it with a high frequency.

Further, since it is possible to wash the inside of the apparatus with a water jetting facility and to dry the washed one by high frequency heating, if the apparatus of the present invention is installed in, for example, a laboratory, it will be contaminated in the laboratory. Since it is possible to easily sterilize, wash, and dry the object, it is possible to reuse the experimental equipment in a short time without requiring complicated labor as in the past. The excellent effect that the labor efficiency is promoted and the work efficiency can be improved is obtained.
