2. Description of the Related Art A rotary-type drying device is one in which an object to be dried is attached and dried on the surface of a drum, which is represented by a rotating drum dryer, and another object is to carry the object to be dried into a rotating drum and agitate while rotating. In some cases, dry air or steam is supplied to the inside of the drum or from the outside of the drum to dry it. The present invention supplies dry air inside the rotating drum,
Japanese Patent Publication No. 58-50159 can be cited as a device that belongs to a device that dries while rotating, and that belongs to the conventional device. This prior patent has a structure in which a plurality of scraping blades are arranged along the circumferential surface of the inner wall of a rotary cylinder, and the scraping blades can be driven so as to overlap each other. With this structure, even a processed material with a high water content is prevented from adhering to the blades, and the blades act to scrape the processed materials that have adhered to each other, so that the processed objects are evenly contacted with the hot air. It is supposed to do. In this invention, the processed material is supplied from the upper part of one end of the rotary drum and discharged from the lower part of the other end, the dry air is created by the combustion of the burner, and the rotary drum is a roller on which the rail on the outer circumference of the drum rotates. It is arranged so that it rides on top of and is rotating. In addition, Japanese Examined Patent Publication No. 2-23240 puts a processed material in a cylinder having a large number of molding / ventilation holes on its peripheral wall and rotates it in a drying chamber to dry it. By providing a pressure difference between and, the semi-dried processed product is extruded from the molding / ventilation hole to obtain a chip-shaped dried product. A major object of the present invention is to obtain a certain granular dry product, which is realized by the holes provided in the peripheral wall of the rotary cylinder serving as the inlet / outlet of dry air and the outlet of the granular dry product. Furthermore, the holes play a role of separating water in the initial stage of the high-moisture treated material, and it is also possible to devise a method of performing pretreatment of rotary drying. The dry air is supplied from one of the drying chambers, passes through the peripheral wall of the rotary cylinder, and is discharged from the internal dry air outlet.
Rotation of the rotary cylinder is carried out by a motor connected to a short tube connected to one wall of the rotary cylinder, the cylinder itself being placed on a rotatable roller arranged in a drying chamber.
For loading and unloading the processed product, the processed product is loaded from the inlet provided on the other wall where the rotating short tube of the rotary cylinder is installed, and is extruded into chips from the rotary cylinder in a semi-dry state, and the floor inside the drying chamber It is deposited on the surface and is carried out to the outside of the drying chamber in fixed amounts. Although the carrying out is not specifically described, the structure is understood to be carried out by a person with a scoop or the like. Next, Japanese Patent Application Laid-Open No. 4-157000 is for adjusting the amount of heat in a rotary dryer by detecting the temperature of the exhaust gas, the required power of the rotary drum, the amount of processed material, and the like. The apparatus of the present invention has a structure in which a stirring blade for the processed material is arranged on the inner wall of the rotating drum, and a separate rotating blade for stirring is built in, and the processed material is supplied from one side of the rotating drum and discharged to one side. And the dry air is supplied by the burner. Further, the rotation of the drum is performed by a roller that is in contact with the outer circumference of the drum. In the case of the present invention, the blades fixed to the rotary drum and the rotary blades that are driven to rotate separately effectively agitate the processed material.

[0003]

SUMMARY OF THE INVENTION A rotary-type drying device, in which a processed product is put into a rotary cylinder and dried, is roughly classified into a structure for loading / unloading the processed product, a structure for stirring the processed product during rotation, It is composed of three structures for supplying and discharging dry air. There are both batch type and continuous type as the processing form, but the most problematic ones are the method of loading / unloading the processed material and the stirring of the processed material during rotation. In particular, the agitation depends on the water content of the processed material, and even if a stirring blade is provided, it adheres to the blade and solidifies, losing the agitation function, and the processed material sticks to the wall and cannot be carried out, or rotates. The weight of the drum may be unbalanced and the rotation control may be affected, resulting in a dangerous situation. Therefore, in the rotary dryer, the treated material is uniformly carried in and the stirring is performed so as not to form a large lump,
It is necessary to prevent adhesion and solidification on the walls and stirring blades, and to take out the processed product smoothly from the drum after the completion of drying. In Japanese Patent Publication No. 58-50159 of the prior art, a plurality of scraping blades are arranged along the inner peripheral surface of the rotary cylinder, and
The scraping blades are structured so that they can be driven so as to overlap each other, and even if the processed objects have a high water content, they are prevented from adhering to the blades. It acts so as to scrape, so that the processed material comes into uniform contact with the hot air. Due to the structure and purpose of the blades, the shape and number of the rotary blades are limited to a fixed value, and there is no opportunity to scrape the processed material attached to the back side of the blades.
Further, if maintenance of the rotary shaft in the blade drive connection portion is neglected, it will not operate due to the processed material attached thereto, or will not operate due to corrosion due to the influence of moisture of the processed material. When even one blade stops operating, it affects other blades that are in contact with each other, and the blade of one round of this portion cannot be used. It is conceivable to apply grease or the like to the shaft portion, but in the case of organically processed products for drying foods or reusing dried products as fertilizers, the incorporation of greases is not preferable because it will reduce the product value. Further, since the dried product is discharged from one end of the drum, it is difficult to carry out the product without taking measures such as allowing the drum to be tilted, and a problem remains in carrying out the processed product after drying. .

In Japanese Patent Publication No. 2-23240, a processed material is put in a cylindrical body having a large number of molding / ventilation holes in its peripheral wall, and this is rotated and dried in a drying chamber. By providing a pressure difference between the drying chamber and the drying chamber, the semi-dried processed product is extruded from the molding / ventilation hole to obtain a chip-shaped dried product. A major object of the present invention is to obtain a certain granular dry product, which is realized by the holes provided in the peripheral wall of the rotary cylinder serving as the inlet / outlet of dry air and the outlet of the granular dry product. However, the holes tend to be clogged with the processed material, and it remains doubtful that the holes will be completely secured even when dropped due to the self-weight described, and some measures such as injecting high pressure air to secure the holes must be taken. There is concern that dry air will not pass through the cylinder. In addition, when loading or unloading the processed product, the processed product is loaded from the inlet provided on the other wall of the rotary cylinder where the rotating short tube is located, and is pushed out in the form of chips from the rotary cylinder in the semi-dried state. It is configured to be deposited on the floor surface of and to be carried out to the outside of the drying chamber in fixed amounts. The carrying out is not specifically described, and it is understood that a person carries it out with a scoop, etc., but this is a method with poor workability, and it is necessary to add some hand such as tilting the floor of the drying room There is. In addition, the rotation of this case is to support the cylinder with a roller and rotate the rotating shaft, but the roller that supports the cylinder is on the floor of the drying chamber, and if semi-dried processed material accumulates on it, If they are attached or clogged on the rotating shaft, they will interfere with the rotation. In a rotary dryer, it is dangerous to leave the cause of load on the rotation and corrosion of the rotary shaft, and maintenance of the device is expensive and time consuming.

Next, Japanese Patent Laid-Open No. 157000/1992 discloses a rotary type dryer for detecting the exhaust gas temperature, the required power of the rotary drum, the amount of processed material, etc. to adjust the amount of heat. In addition to arranging the stirring blade of the processed material on the inner wall of the rotating drum, the apparatus of (1) has a separate rotating blade for stirring, and the processed material is supplied from one of the rotating drums and discharged to one. Dry air is supplied by the burner. Blades fixed to the rotating drum,
It can be seen that the processed material is effectively agitated with the rotating blades that are separately driven, but measures against the processed material adhering to the blades have not been considered, and in particular, the blades fixed to the rotating drum are hook-shaped. If it adheres to the inside and solidifies, it may not be discharged. Therefore, the present invention has a structure in which the stirring blades fixed to the rotating drum do not easily adhere to the processed material, and does not bother loading and unloading the processed material. An object of the present invention is to obtain a rotary dryer that does not hinder rotation.
