Abstract

PURPOSE:To simplify work and shorten the working time by taking out an inner layer filter, together with dust, from an outer layer filter when the dust caught into a bag shaped filter consisting of the inner and outer layers discharged, and by installing a new inner layer filter, together with the outer layer filter, as an inner and outer layer bag-shaped filter on the air discharge port of a drying machine. CONSTITUTION:When a filter 1 which is installed in demountable manner by a stop ring 4 at the air discharge port 3 of a tumbler drying machine or dry cleaning machine 2 becomes full of dust 5 such as fiber dust, the filter 1 is demounted from the air discharge port 3 by demounting the stop ring 4. The inner layer filter 1a of the filter 1 is taken out, together with the dust 5, from the outer layer filter 1b of the taken out filter 1. Then, a new inner layer filter 1a is inserted into the outer layer filter 1b, and installed at the air discharge port 3 and fixed by the stop ring 4. Since the inner layer filter 1a which is taken out together with the dust 5 is of a thrown-way type, the inner layer filter 1a is discharged or burnt together with the dust 5.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method and apparatus for discharging dust generated from a dryer such as a tumble dryer or a dry cleaning machine.

(Conventional technology) Tumblers generally used in cleaning factories, etc.
In a dryer or dry cleaning machine, etc., when clothes or other textile products are loaded and dried or dry cleaned, the inner drum of the tumble dryer or dry cleaning machine, etc. Clothes and other textile products are worn out due to friction with clothing or other textile products loaded in the bag or mutual friction between clothing and other textile products, and dust such as textile waste is generated.

For this reason, as shown in FIG. 2, a filter 1' has been conventionally attached to the exhaust port of a tumble dryer, dry cleaning machine, or the like to collect dust such as textile waste.

(Problem 8 to be solved by the invention) The conventional filter 1' attached to the exhaust port 3 of a tumble dryer or dry cleaning machine 2, etc. is a single layer filter made of expensive cloth and formed into a bag shape. In order to improve the dust collection efficiency, the inner surface of the filter 1' is brushed like a blanket.

As described above, since the filter 1' is expensive, conventionally the dust 5 collected on the filter 1' is transferred to the filter 1'.
’, then put the filter 1’ in the tumbler again.
It is attached to an exhaust port 3 of a dryer or dry cleaning machine 2 or the like.

As mentioned above, although the conventional filter 1' improves the dust collection efficiency, the dust 5 such as fibrous dust gets into the nap, so the dust 5 collected on the filter 1' and the filter 1 ′ is not easy to separate from
It takes 30 to 40 minutes of work time to take out the dust 5 from the filter 1' and set the filter 1' again. Grab Dust 5,
You have to hit filter 1'.

Dust was unavoidable and the working environment was poor.

(Means for Solving the Problems) According to the present invention, a bag-like filter having two layers, an inner layer and an outer layer, which can be separated from each other, is provided at the exhaust port of a dryer, and means for enhancing the dust collection effect is provided on the inner surface of the inner layer filter. The outer layer filter functions as a reinforcing material for the inner layer filter, and when the dust collected in the inner and outer bag-shaped filters is discharged, the inner layer filter is removed from the outer layer filter as dust. There is obtained a dust discharge method characterized in that the new inner layer filter and the outer layer filter are taken out together and attached to the exhaust port of the dryer as a two-layer bag-like filter.

Furthermore, according to the present invention, a bag-like filter having two layers, an inner and outer layer, which can be separated from each other, is removably attached to the exhaust port of the dryer,
The inner surface of the inner layer filter is equipped with a means to enhance the dust collection effect, and the outer layer filter functions as a reinforcing material for the inner layer filter. When discharging the dust, remove the inner layer filter from the outer layer filter along with the dust.
There is obtained a dust discharge device characterized in that a new inner layer filter can be attached to the exhaust port of the dryer together with the outer layer filter as a two-layer bag-like filter.

(Example) Next, an example of the present invention will be described with reference to the drawings.

Referring to FIG. 1, a dust discharge device according to an embodiment of the present invention has a filter 1 detachably attached to an exhaust port 3 of a tumble dryer, dry cleaning machine 2, etc. with a retaining ring 4. There is.

This filter 1 is an inner layer filter 1a formed in a bag shape.
It is formed of two layers: and an outer layer filter 1b, and the two can be separated from each other.

The inner layer filter 1a is formed of a nonwoven fabric such as nylon, rayon, or polyester, and its inner surface is designed to enhance the dust collection effect, such as by being raised.

Note that this filter 1a does not need to be very strong in terms of strength, so its thickness is between 15 g/rrr and 30 g/rr.
Use a thin one with a thickness of about 300 ft.

Further, the outer layer filter 1b is made of cloth similar to conventionally known filters, and mainly functions as a reinforcing material for the inner layer filter 1a. Therefore, there is no need for the inner surface of the outer layer filter 1b to be designed to enhance the dust collection effect, such as raising naps, as in the past.

Since the inner layer filter] a is formed of an inexpensive nonwoven fabric, it can be manufactured at a lower cost than the outer layer filter 1b made of cloth. Specifically, the price of the outer layer filter 1b is 10,000 yen, and the price of the inner layer filter 1a is about 1,000 yen.

Next, its effect will be explained.

As shown in Fig. 1, when a filter 1 which is removably attached to the exhaust port 3 of a tumble dryer or dry cleaning machine 2 with a retaining ring 4 is full of dust 5 such as textile waste, stop it. Remove ring 4 and remove filter 1 from exhaust port 3.

Then, remove the outer layer filter lb of filter 1.
The inner layer filter 1a is taken out together with the dust 5.

Next, add a new inner layer filter to the outer layer filter 1b] a
is inserted, attached to the exhaust port 3, and fixed with the retaining ring 4 to complete exhaustion of the dust 5.

Note that the inner layer filter la extracted together with the dust 5 is disposable, so it is discarded or incinerated together with the dust 5.

(Effect of the invention) According to the present invention, the filter has two layers, the inner and outer layers.

Since the dust can be discharged by simply pulling out the inner layer filter together with the dust, it is an extremely simple one-step process, and the nine-work time can be reduced to about 1/10 of the conventional method.

Moreover, unlike the conventional method, dust is not generated when discharging dust, so that the working environment can be improved.
