Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for cleaning products filled in a bag by forcibly blowing ozonized air into the product.

[Conventional technology]

Conventionally, products to be filled in bags, such as feathers, are exposed to ozonized air to sterilize, deodorize, and whiten them.

Feathers are produced in Taiwan, China, the United States, Canada, etc. after clipping the feathers of Datsuku or waterfowl, washing them with water, washing them with detergent, and drying them with hot air to make bedding and other products.
It was used as a material for winter clothing. However, although dirt such as feces on the feathers can be removed and the appearance is beautiful, animal fats and oils attached to the filaments around the center of the feathers cannot be washed thoroughly and remain. Oxidation and deterioration of animal fats and oils may cause them to emit strange or foul odors.
Discoloration occurred over time.

On the other hand, in 1980, a device was developed to clean organic contaminants adhering to the surface of the object to be cleaned by generating ozone with the light of an ultraviolet lamp and decomposing the ozone with the generated oxygen. It is disclosed in Publication No. 2537.

This conventional cleaning device has an ultraviolet lamp placed inside a box equipped with an air suction port and an air discharge port, an ozone-free quartz tube installed at the position where the ultraviolet rays generated by the ultraviolet lamp are irradiated, and a circulation fan. The ozone is decomposed by passing it through an ozone-free quartz tube.

[Problem to be solved by the invention]

By the way, since the conventional cleaning device cleans organic contaminants using oxygen generated when ozone is decomposed, it is effective against animal fats and oils that adhere to filaments that are directly exposed to ozone, such as feathers. There is no power to break it down into, in other words,
There is a problem in that cleaning equipment cannot be used for feather products.

In addition, since it is used at normal pressure, it is not possible to penetrate the inside of the entangled filaments sufficiently, resulting in the problem of insufficient internal cleaning, similar to the conventional cleaning of feathers.

The present invention has been made to solve this type of problem, and by releasing ozonized air in a bag placed inside the cleaning treatment chamber and activating a negative pressure source connected to the treatment chamber. An object of the present invention is to provide a cleaning device using ozonized air that can reduce the pressure inside a bag and fill the inside of a workpiece with ozonized air.

[Means to solve the problem]

To achieve the above object, the present invention provides a cleaning treatment chamber having an inlet and an outlet for ozonized air;
It consists of a blow-off pipe connected to the inlet and opened in a bag disposed inside the cleaning processing chamber, and a negative pressure supply source connected to the cleaning processing chamber, and under the depressurizing action of the negative pressure supply source. The bag is characterized by being filled with ozonized air.

[Effect]

In the cleaning device according to the present invention, the blowing pipe is opened inside the workpiece filled with the bag, and ozonized air is supplied under reduced pressure. Therefore, the ozonated air can penetrate into the inside of the workpiece and be directly exposed to ozone.

b, 4c, and blowout bags 3a, 3b, 3
After adjusting the length so that it is opened within c, the cleaning processing chamber 2 is tightly closed.

Next, the air compressor 13 is operated to compress the air in the atmosphere and send it into the ozone generator 4 to produce 7,000~
Generates ozonized air with a concentration of 8000ppm. This ozonized air is sent to the ozonized air blower 6, where it is diluted to approximately 50 ppm, and then supplied to the cleaning processing chamber 2 via the supply pipe 7. Then, it is discharged from the blow-off ports of the blow-off pipes 4a, 4b, 4c in the cleaning processing chamber 2 onto the feathers in the bags 3a, 3b, 3c.

At the same time, the seal pot, which is the negative pressure supply source 5, is operated to generate negative pressure, for example, about -20 mmAq, thereby reducing the pressure in the cleaning processing chamber 2. As a result, the air inside the feather filaments filling the bags 3a, 3b, and 3c can be replaced with ozonized air, and the animal fats and oils adhering to the filaments can be directly exposed to ozone. This prevents ozone from leaking outside and protects the health of workers.

The ozonized air supplied to the cleaning chamber 2 returns to the ozonized air blower 6 from the return pipe 8, forming a circulation circuit for supplying the ozonized air to the cleaning chamber 2 again. Further, the ozonized air that has not reacted with the feathers is sucked into the exhaust blower 15 through the exhaust pipe 9 and guided to the unreacted ozonation tube 16, where it is decomposed by activated carbon and becomes oxygen into the air. released inside.

The time that the feathers are exposed to the ozonized air in the cleaning chamber 2 varies depending on the amount of feathers filled in the bags 3a, 3b, 3c, but is 1/10 hour.
Preferably, about 30 minutes is the most suitable time for the animal fats and oils in the feathers to be decomposed.

When the ozone treatment is completed, the air compressor 13 is stopped to end the generation of ozone, and after the ozonized air in the cleaning treatment chamber 2 is sucked by the exhaust blower 15, the bag in the cleaning treatment 2 is taken out. Thereafter, the feathers can be washed by repeating the same operation.

〔Effect of the invention〕

According to the cleaning device according to the present invention, the following effects can be obtained.

By cleaning with ozone, it becomes possible to decompose animal fats and oils. Therefore, even if the feathers are of poor quality, they can be processed into high quality feathers, maintaining their effectiveness over a long period of time.
It can fully demonstrate heat retention and airtightness.

Additionally, during the cleaning process, the pressure inside the cleaning chamber is reduced, which allows the air inside the feathers to be replaced and exposed to ozone, while also preventing ozone from leaking outside the cleaning chamber. , has no adverse effect on the human body or plants.
