(Prior Art) Conventionally, this type of dryer 100 is shown in FIGS. 9 and 10.
As shown in the figure, a rotary drum 105 is rotatably supported via bearings 104 between the left and right side walls 103 of a machine frame 102 which has a drying chamber 101 and is coated with heat insulating material inside. A mesh steel plate is formed into a cylindrical shape with a predetermined diameter by drilling a large number of perforated holes with a predetermined diameter into the steel plate, and a side plate 106 having a rotating shaft 101 is attached to the left and right sides to form a rotating drum. A partition wall 108 is provided in the drum 105 to divide the drum 105 into, for example, three dough chambers A, B, and C.

At B and C, openings 109 for inputting and unloading the dough W are formed so as to be openable and closable. The rotating drum 105 provided in this manner is a rotary drum! ll device 110 so as to rotate at a predetermined rotational speed.

Furthermore, a combustion device 111 that uses city gas or LPG as fuel, for example, is disposed on the bottom side of the machine frame 102.

Note that 112 is a cylinder provided on the upper side of a separate frame, and the drying chamber 101 inside the machine frame 102 is communicated with the atmosphere via the cylinder 112.

(Problem to be Solved) Therefore, in order to dry the fabric W using the conventional dryer 100, first, the rd fabric is half or slightly larger than the volume of each fabric chamber A, B, and C. W is input and rotated by the drive device 110, and the inside of the drying chamber 101 is heated and maintained at a predetermined temperature by the combustion heat of the combustion device 111, and the dough W is heated while being stirred by the rotation of the drum 1o5. It dries almost evenly. Therefore, if the dough W put into each dough chamber A, B, and C is to be dried in the same drying time, in order to take it out after drying is completed, rotate the rotary drum 100 and open the take-out port 1.
09 facing downward, the hatch is unlocked and the outlet 109 is opened to take out the dry dough W. In this downward position, the dough W is ejected all at once, so care must be taken to prevent it from being scattered. Therefore, it takes a long time to take out the entire fabric from each drying chamber A, B, and C, and the drying time for the fabric put into each drying chamber A, B, and C is very long. If j' is increased, the stop F time for taking out the product after each drying becomes longer, resulting in a problem that the time required for the entire drying becomes longer.

Next, the operation of this embodiment configured as described above will be explained.

First, when drying the fabric W8, the drying time is determined in advance based on experience, depending on the shape and size of the fabric W8.

Therefore, for example, three types of fabrics Wl, W2. When drying W3, put it into the dough chambers A, B, and C in that order. Each of these fabrics W1. W2
．． The W3 charge meter feeds dough until each dough chamber A, B, and C is filled. In this case, each outlet 25 of the partition wall 19, 20 is closed by a lid 26. After that,
The hatch of the input port 21 and the lid 13 of the machine frame 2 are closed.

Then, the low-speed drive motor 30 is started, and the infrared combustion device e258 is ignited. As a result, the rotating drum 16 is rotated at 1r, p, i. And then, send 1! Ifi55 is raised IJJ. During the rotation process of the drum 16, the temperature of the air in the drying chamber 10 is increased, and the rotating drum 1
6, each of the fabrics Wl, W2. W3 is heated by the combustion device 58, and is exposed to the heated air in the drying chamber 10 to dry each fabric W1. W2. The moisture content in W3 is evaporated and drying is promoted. The combustion device 58 is detected by a temperature sensor when the temperature inside the drying chamber 10 reaches a predetermined temperature, and at the same time, the combustion device 58 is switched to single-row combustion. On the other hand, by driving the air blower R55, the heated air in the drying chamber 10 is transferred to the intake pipe 1.
4 and introduced into the blower 55,
Furthermore, air is blown into the rotating shaft 22 of the rotating drum 16.

The heated air blown into the rotating shaft 22 is passed through the blowing holes 24 provided through the rotating shaft 22 to each of the dough chambers Δ, B,
C is radially ejected as hot air in the direction of the outer periphery of the cloth W1. W2. W3 is heated to accelerate drying. In this way, each fabric W1 in the rotating drum 16. W2. During the rotation process of W3, drying is promoted both from the outer periphery and from the center. When the required drying time for the fabric W1 is reached, a manual handle 50 is attached to the chain wheel 48 of the opening/closing device 37, and the lid 28 of the outlet 27 provided on the left side plate 17 is rotated in the direction of opening. The lids 28 are simultaneously opened and moved via the threaded rods 43, and the dough W1 is naturally flowed out from each outlet 27 due to the rotation of the drum 16. This discharged dough W1 is stopped by a hopper 59 and guided to the outside of the machine frame 2 through a chute 60. When the amount of dough W1 entering the dough chamber becomes small, the dough W1 is automatically discharged by being guided to the take-out slot 27 side by a blade 16a attached to the inner periphery of the dough chamber Δ. Therefore, during this time, the dough W1 can be taken out without requiring the same amount of labor, and if a conveyor or the like is provided on the chute 60 side, it can be easily transported to the next process.

Next, when the removal of the fabric W1 is completed and the required drying time for the next fabric W2 is reached, the rotation of the drum 16 is temporarily stopped, and the lid 13 on the fabric A side and the hatch in the fabric chamber A are opened. After opening the lid 26 of the outlet 25 provided in the partition wall 19, the lid 13 is closed again and the drum 16 is rotated. Due to this rotation, the dough W2 in the dough chamber B is moved to the dough chamber A, and the moved dough W2 is transferred to the blade 1.
6a and is discharged from the outlet 27 of the left side plate 7. Hereinafter, in the case of the dough W3 as well, when the required drying time is reached, the dough W3 can be automatically taken out by opening the take-out port 25 of the side plate 18 in the same manner.

Therefore, in this embodiment, the intake pipe 14 is placed inside the artificial frame 2.
At the same time, the rotating shaft 22 of the rotating drum is formed into a cylindrical shape having a hollow part, and a plurality of ejection holes 24 are provided radially around the axis at predetermined intervals to form the intake pipe 14.
Since the blower 55 is interposed between the rotary drum 16 and the rotary shaft 22, the heat mass that has heated the outer periphery of the rotary drum 16 is further circulated to the center of the rotary drum 16 and heated from the inside, thereby saving energy on fuel. You can also measure the dough chamber Δ
, B, and C are filled with dough W, the rotating drum 16 can be heated from the inside and outside to dry it evenly, thereby shortening the drying time and drying the dough in mass production. It is something that can be done. In addition, in the conventional dryer 100, when taking out each dough W from the dough chambers A, B, and C which are divided and provided in the rotating drum 105, the input/take-out port 109 is placed in the lower position. For this reason, since the fabrics are discharged all at once, processing is very time-consuming.In particular, according to this embodiment, the rotating drum 16 is used to collect the fabrics WA and B.

A take-out port 25 is provided in the partition wall 19.20 partitioned into C so that it can be opened and closed, and a take-out port 2 is provided in the left side plate 17.
7 is attached with an opening/closing device 37 so that it can be opened and closed, so that the dry dough W1. W2. The dough W3 can be taken out very easily and the time taken out can be shortened, and the dough W3 having different drying times can be placed in each dough room A and B according to their order.

C and each dough W1. W2. The stopping time after drying W3 can be shortened as much as possible, and the fabric W3 can be dried almost continuously.
1. W2. Since drying and removal of W3 can be carried out efficiently, each fabric W1. W2. The drying time of the W3 body can be shortened and the drying efficiency can be increased.

For example, if m of the dough W is equal to the volume of the dough chambers A and B, the spout hole 24 in the dough chamber C portion of the rotating shaft 22 of the rotating drum 16 is closed by a closing member (not shown). Only dough chambers A and B can be used.

Next, FIG. 8 shows another aspect of the means for taking out the dough W.
7 is provided so that its left opening can be opened and closed with respect to the rotating drum 16, and a threaded rod 61 is attached to the left opening side of the rotating drum 16 in a direction perpendicular to the rotation @ 22 as shown in the figure. It is connected and supported. Further, the left side plate 17 is integrally attached to a slide member 62 which is slidably fitted to the shaft member 23 of the rotation @ 22 by welding means or the like, and one end of this slide member 62 has a flange to which the side plate 17 is attached. A threaded portion 64 is formed on the outer periphery of the other end.

Further, a female thread member 65 is screwed onto this threaded portion 64,
A chain wheel 66 for opening and closing the side plate 17 is attached to the separation screw member 65. Further, the shaft member 23 has a female screw member 65.

At the same time, the fixing collar 67
A row 571 that restricts the movement of the female threaded member 65 is attached. Note that the other configurations are the same as those in the above embodiment. Therefore, when the female screw member 65 is rotated via the manual handle 50 in a direction that closes the opening of the rotating drum 16, the slide member 62 screwed thereon moves to the right in the figure along the shaft member 23. It is moved and comes into contact with the opening edge of the rotating drum 16 to close it. In this case, the movement of the female screw member 65 is regulated by the roller 71, and the reaction force when the opening is closed is stopped by the thrust bearing, so that each slide member 65 can be firmly closed. , female thread member 6
5 fixing collar 67 is rotated together with rotating drum 16. Furthermore, the entire opening is opened by operating the manual handle 50 to take out the dough W, so that the time required to take out the dough W can be shortened. Note that this opening/closing means is suitable, for example, for a large rotating drum in which the rotating drum 16 does not have partition walls 19, 20 and that dries one type of fabric W.

In addition, in the above embodiment, the case of drying and covering cloth such as hail was exemplified, but it can also be applied to drying in fields and the like.
