Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to drying and separation of fabrics such as sesame/vei, hail, etc.

(Prior art) Conventionally, this type of drying V1100 is shown in Fig. 9 and Fig. 1.
As shown in Figure 0, a rotary drum 105 is rotatably supported 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, through bearings 104. A thin steel plate is formed into a cylindrical shape with a predetermined diameter by forming a mesh steel plate with a large number of perforated holes having a predetermined diameter, and a side plate 106 having a rotating shaft 107 is attached to the left and right sides. A rotating drum 105 is formed, and a partition wall 108 is provided inside the drum 105 to divide it into, for example, three dough chambers Δ, B, and C, each of which has a dough chamber A.

In B and C, openings 109 for inserting and removing dough W having hatches that can be opened and opened are formed. The rotary drum 105 provided in this manner is connected to the rotary drum 105 by a drive 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 the machine frame, and the drying chamber 101 inside the machine frame 102 is communicated with the atmosphere via the cylinder 112.

(Problem to be resolved w4) Therefore, in order to dry the fabric W using the conventional dryer 100, first, the capacity of the fabric W is half or slightly larger than the volume of each fabric chamber A, B, and C. The dough W is put in 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 105. It dries almost evenly. However, in this conventional dryer 100, the dough W is stored in each of the dough chambers A and B.

Add (6), which is half or slightly more than the volume of C, and tj! Since it dries in an itchy manner, there is a problem in that it is not transient, and the amount of heat generated by the combustion device 111 is immediately released from the cylinder 112 into the atmosphere after heating the dough W in the drying chamber 101 and the rotating drum 105. There were problems such as extremely large heat loss as the heat was released into the interior.

A hopper for taking out the left side plate 17 of the rotating drum 16.
A chute 60 is provided at the lower part of the chute 60 so that the dried dough W can be guided out of the machine frame 2.

Although not shown, an opening/closing means is provided between the chute 60 and the left side frame 5 in an airtight and heat insulating manner.

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

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

Therefore, for example, three types of fabrics W1. W2. When drying W3, put it into the dough chambers A, B, and C in that order. Each of these fabrics Wl, W2
．． Add the amount of W3 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 r! Ignite 158. As a result, the rotating drum 16 is rotated at 1r, p, m. And then, send it! One aircraft 55 is activated. During the rotation process of the drum 16, the temperature of the air in the drying chamber 10 is increased, and the dough chambers A, B, and C of the rotating drum 16 are filled with each dough W1 on the outer circumferential side. 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 W3.
1. W2. The moisture content in W3 is evaporated and drying is promoted. Note that when the temperature inside the drying chamber 10 reaches a predetermined temperature, the combustion device 258 is detected by a temperature sensor, and at the same time, the combustion device 258 is switched to single-row combustion. On the other hand, by driving the blower 55, the heated air inside the drying chamber 10 is drawn in t! 14
is inhaled from the branch pipe 15 and introduced into the air blower 1155,
Furthermore, air is blown into the rotating shaft 22 of the rotating drum 16.

The heated air blown into the rotating shaft 22 is sent to each of the dough chambers A, B, and
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 lid body 28 is simultaneously opened and moved via the screw rod 43, and the dough W1 is naturally flowed out from each outlet 27 by 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 in the dough chamber A decreases, the dough W1 is automatically discharged by being guided to the take-out slot 27 side by a blade 16a attached to the inner peripheral surface of the dough chamber A. Therefore, the dough W1 can be taken out without having to obtain anything during this time, 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 dough W1 is completed and the required drying time for the next dough W2 is reached, the rotation of the drum 16 is temporarily stopped, and the lid 13 on the dough chamber A side and the hatch of the dough chamber A are opened. After opening the lid 26 of the outlet 25 provided in the partition wall 19, the hatch and lid 13 are 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 similarly opening the take-out port 25 of the steel plate 18.

Therefore, in the conventional dryer@100, the dough chambers A and B are separated and provided in the rotating drum 105.

When taking out each dough W from C, input/take out port 109
It is necessary to take out the dough W with the rotating drum 1 in the lower position, and therefore, the dough is discharged all at once, which requires an extremely troublesome process. However, according to this embodiment, the rotating drum 1
A take-out port 25 is provided in the partition wall 19.20 that divides the dough chamber A, B, and C into fabric rooms A, B, and C, and an opening/closing device [37 is attached to the take-out port 27 opened on the left side & 17 so that it can be opened and closed. Since it is provided, the fabric W1. W2. It is possible to take out the W3 very easily, and the dough W3 having different drying times can be placed in each dough room A according to their order.

Put the dough into B and C and almost continuously add the dough Wl, W2. Drying and taking out of the dough W3 can be carried out efficiently. For example, if m of the dough W is only the volume of the dough chambers A and B, the drying and taking out of the dough chamber C of the rotating shaft 22 of the rotating drum 16 can be carried out efficiently. Although the ejection holes 24 at these parts are not shown, they can be closed by a closing member so that only the fabric chambers A and B can be used. Also, especially
In this embodiment, the intake pipe 14 is disposed within the machine frame 2, and the rotating shaft 22 of the rotating drum is formed into a cylindrical shape with a hollow part, and a plurality of pipes are arranged radially around the axis at predetermined intervals. A blowout hole 24 is provided to connect the intake pipe 14 and the rotating shaft 22.
Since the blower 55 is interposed between the rotary drum 16 and
It circulates to the center of the drum 16 and heats it from the inside, making it possible to save energy on fuel.Furthermore, even when the dough chambers A, B, and C are filled with dough W, it is heated from the inside and outside of the rotating drum 16. The fabric can be dried evenly, the drying time can be shortened, and fabrics can be dried in mass production.

Next, FIG. 8 shows another embodiment of the means for taking out the dough W. This taking out means includes the left side plate 1 of the rotating drum 16.
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 rotating shaft 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 slidably fitted to the shaft member 23 of the rotating shaft 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 1166 for use between the surfaces of the side plate 17 is attached to the same layer screw member 65. In addition, the shaft member 23 has a female screw member 6.
The thrust bearing in contact with the end face of 5 is llI!
The fixing collar 67 shown in FIG. A row 571 is attached which restricts the movement of the female threaded member 65 by means of the fixing collar 67. 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 restricted by the a-rough 1, and the reaction force when the opening is closed is stopped by the thrust bearing, making it possible to firmly close each slide member. 62, the collar 67 for fixing the female screw member 65 is rotated together with the rotating drum 16. In addition, the entire opening is opened by operating the manual handle 50 to take out the dough W.
The unwinding time 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 dough such as gravy was exemplified, but it can also be applied to drying vegetables etc.

(Effects of the Invention) Now, the present invention rotatably supports a mesh-like rotating drum that can be ventilated inside and outside in a drying chamber, and the rotating shaft of the rotating drum is provided penetrating the center of the rotating drum. The drying chamber is formed into a cylindrical body having a hollow part and has a large number of holes extending therethrough, and the drying chamber is provided with an intake pipe having a plurality of branch pipes through which air from the same chamber can be taken in. By configuring the intake pipe and the rotating shaft to be connected to the ventilation M via the feed J[, the amount of heat that has heated the outer periphery of the rotating drum is further circulated to the center of the rotating drum and heated from the inside, so that the fuel In addition, even if the rotating drum is filled with fabric, it can be heated from the inside and outside of the rotating drum to dry evenly, reducing drying time.
In addition, it can dry fabrics in mass production, making it extremely useful as a dryer.
