Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drying device for drying washed or dyed cloth while moving it.

Dryers for drying cloth are divided into two categories depending on the drying method: hot air, contact heating, superheated steam, and dielectric heating. Among these dryers, the hot air dryer dries the treated fabric rapidly, so it is superior to other dryers in terms of migration, texture, etc. Widely used for final drying.

By the way, the method of naturally drying the cloth to be treated is superior to the above-mentioned hot air dryer in terms of migration and texture, and is the most preferable drying method from the viewpoint of quality. The problem is that it is fragile and is easily affected by the weather.

Therefore, the purpose of this invention is to provide an apparatus for drying chirimen, which can achieve almost the same effect as natural drying, and which can perform drying processing efficiently. It is said that

This invention has a structure in which the fabric to be treated can be transferred between two or more bar conveyors for conveying the fabric to be treated inside the drying box.
2. Each conveyor is installed at 'FJ direction number 2YJ\]
.

The spray duct is rearranged, and during the movement of the fabric to be treated, which is carried down from the drying box to the outlet by the front bar conveyor (here, the spray duct is The cloth to be treated is dried by blowing dry air toward the treated cloth.

1. One embodiment of the present invention will be described based on the accompanying drawings.

According to oral tradition, there are 4 coats inside the drying box 1! L
Bar conveyors 2 for burial and conveyance are provided at each stage ζ above and below. An end register canvas 4 is attached to the outer side 1 of the endless conveyor bar 3 of this bar conveyor 2, as shown in FIG.

The number of endless canvases 4 is arbitrary, and in the illustrated embodiment, three canvases 4 are provided with a required spacing between the canvases 4. Each of these conveyors 2 is driven so that the moving directions of the conveying surfaces of the conveyors 2 facing each other at the top and bottom are different, as shown by the arrows in FIG.

The end of the bar conveyor 2 on the unloading side of the cloth to be treated is located outside the end of the unloading side of the cloth to be treated (
With this configuration, the fabric to be treated falling from the discharge side end of the conveyor 2 is received by the lower conveyor 2 and further conveyed by the conveyor 2.

The carry-in end of the bar conveyor 2 located at the top of the drying box 1 protrudes outward from the cap 5 provided at the top of one of the IHHn plates of the drying box 1, and touches the top surface of the protruding end. A roller 6 is provided by melting, and the roller 6
The fabric to be treated is placed between the ends of the bar conveyor 2 and the end of the bar conveyor 2. In addition, the end of the lowest bar conveyor 2 on the discharge side is
It protrudes from the lower protrusion provided at the bottom of the side plate of the drying box 1 on the 1 sacral side.

Now, when the cloth S to be dried is inserted between the bar conveyor 2 and the roller 6 at the top [2], the cloth S to be treated is conveyed by the bar conveyor 2, When it is conveyed to the end of the bar, it falls from this point and is weighed by the bar conveyor 2 below, is further conveyed by this bar conveyor 2, and is finally discharged from the output lower by the belt conveyor 2 at the lowest stage. .

Before β [4 dry-, inside upper part of box 1 is 4 of the cloth to be treated.
A partition plate 8 is provided horizontally so as not to impede the movement of the drying box, and the interior of the drying box 1 is divided into an L chamber 9 and a royal room 10 by this partition plate 8.

A hot air blowing duct 11 is provided above the bar conveyor 2 located in the L chamber 9, and the hot air blowing duct 11 and the heated air blowing tube 13 of the heated air generator 12 provided outside the drying box 1 are connected to each other through the duct. We meet and communicate with 14 people. Further, a duct 16 connected to the blowing node 15 of the heated air generator 12 is connected to an outlet 17 formed at the end of the back plate of the upper chamber 9.

The heated air generator 12 is equipped with a heater 18 and a fan (not shown), and heats the air taken in from the chamber 9 by the rotation of the fan, and supplies the heated air to the hot air blowing duct 11. I'm trying to get an inflow.

A large number of slit-shaped injection holes 20 are provided in parallel on the bottom plate 19 of the hot air blowing duct 11, and heated air is injected onto the endless canvas 4 of the bar conveyor 2 from each of these fl injection holes 20. .

6 notes located in the lower chamber 10 of the drying box 1
Above the conveyor 2, the same number of spray ducts 21 as the endless canvas 4 are provided in parallel to the endless canvas 4. When dry air is supplied to each of the spray ducts 21, this dry air is distributed through a large number of spray ducts 21 formed on the bottom plate. The water is sprayed from the slit-shaped spray holes 22 onto the endless canvas 4.

The air passage cross-sectional area of each blowing duct 21 gradually becomes smaller in diameter toward the conveyance direction of the bar conveyor 2 located below, and a dry air generator is placed at the end on the large diameter side and outside the drying box 1. It communicates with the blowout pipe 24 of No. 23 via a duct 25.

The dry air generator 23 is provided in two ways. This dry air generator 23 has a built-in dehumidifier, although details are omitted in the illustrated embodiment, and the air sucked from the suction tube 26 at the bottom is passed through this dehumidifier to dehumidify the dry air. The liquid is discharged from the blow-off tube 24 in the L section. The above-mentioned suction cylinder 26 of the dry air generator 23 communicates via a duct 27 with a recovery space 29 divided by a vertical partition plate 28 of the royal room 10, and the recovery space 29 and the lower chamber 10 are connected to each other by the vertical partition plate 28.
They communicate through a gap 30 formed in the lower part of the groove.

The drying device shown in the embodiment has the above structure, and its operation will be explained next.

Now, when the h1 hot air generator 12 is activated, the air in the upper chamber 9 is sucked into the generator through the suction port 15, and the effect of the heater 18 provided inside the generator 12 is caused by the force 11.
It is heated and the temperature rises. This heated air is discharged from the blow-off cylinder 13 into a duct 16, flows through the inside of the hot-air blowing tally 11 from this duct 16, and is injected from the injection hole 20 of the duct 11 onto the endless side cloth 4 of the bar conveyor 2.

Note that if the temperature of the hot air blown into the upper chamber 9 becomes high, it will have an adverse effect on the cloth to be treated, so it is preferably about 20 to 30° C. higher than the outside air temperature.

Furthermore, when the dry air generator 23 is operated, air in the recovery space 29 communicating with the lower chamber 10 is sucked into the generator 23 through the duct 27, and dry air dehumidified by the action of the dehumidifier is blown out. It is discharged from the cylinder 24 into the ducts 2 and 5. This dry air flows from the duct 25 to the dry air blowing duct 21, and the injection holes 2 formed in the bottom plate of each duct 21
2 onto the endless canvas 4 of the bar conveyor 2 below it, and when the treated cloth S is inserted between the uppermost bar conveyor 2 and the roller 6 in a state of 5 degrees or more, this treated cloth The S is conveyed by the bar conveyor 2, and when it reaches the end on the discharge side, it hangs down, is received by the lower bar conveyor 2, and is further conveyed. Treated fabric S
When it reaches the discharge end of the conveyor bar conveyor 2, it is received by the bar conveyor 2 below and further conveyed, so that it is finally conveyed out by the bar conveyor 2 at the lowest stage.

When the cloth S to be treated moves in the upper chamber 9 of the drying box 1, this liquid treatment 15 is passed through the spray hole 20 of the spray duct 11.
Since heated air is injected toward the cloth S, the cloth S to be treated is pre-dried.

When the treated fabric S moves in the lower chamber 10, dry air is blown toward the treated fabric 'S from the injection holes 22 of the spray ducts 21 arranged above each bar conveyor 2. The cloth S to be treated is dried and discharged from the output lower.

In addition, as in the example, by pre-drying the cloth to be treated by blowing heated air, the drying speed of the cloth to be treated can be increased, and the conveyance path of the cloth to be treated in the lower chamber can be shortened. I can do this.

As described above, in this invention, the cloth to be treated is conveyed by a plurality of bar conveyors provided in a drying box,
During transportation, dehumidified dry air is blown onto the fabric to be treated.1 This allows the fabric to be effectively dried, and since the drying process does not use heated air, it can be naturally dried. Even after dyeing, it is possible to obtain cloth with a good texture without deterioration or discoloration.

In addition, since the cloth to be treated is conveyed by a plurality of bar conveyors, tension is applied to the cloth to be treated.1. Ideal for drying raspberries, crepe, etc.

Furthermore, since the drying air is circulated between the drying box and the drying air generator, even if odor is generated during drying, it is unlikely to leak outside, and no pollution countermeasures are required. It can be effective.

In addition, the cross-sectional area of the air passage of the blowing duct placed on each conveyor is made gradually smaller in diameter toward the conveyance direction of the conveyor below.
Since the dry air is supplied to the end of the large diameter side, the flow velocity of the dry air flowing inside the spray duct is almost constant, and the dry air can be sprayed evenly from each of the injection holes in the bottom plate. .
