Description

DETAILED DESCRIPTION OF THE INVENTION The present invention processes wood chips, wood chips, bark, waste paper, grass, livestock manure, blue fish bones, pulp sludge, sludge, plastic waste, etc., and reuses them as fuel, or buries them. The present invention relates to an apparatus for compressing and homogenizing raw materials or food materials suitable for reprocessing such as food.

For example, the above-mentioned bark, waste paper, and other waste feathers can be used as fuel by processing them into a solidified state, and the applicant is developing such a granulation device. We have already attempted this and have filed various applications. By the way, since this type of homonuclearization process involves the process of compressing the workpiece, the generation of heat due to this process is unavoidable.

Due to the generation of such heat, the processing die overheats as it continues to operate, resulting in the problem that the compression and solidification of the workpiece cannot be carried out smoothly. Met.

The present invention was developed as a part of such heat countermeasures, and is designed to actively cool the die so that stable nucleation processing can be performed at all times. That is, the apparatus for coordinating powder and granular materials, etc. of the present invention is a device for supplying a workpiece material to a die body provided with a machining hole, and compressing and extruding the material from the machining hole. A cooling medium supply hole is formed in the cooling medium.

The present invention will be explained in detail below based on illustrated embodiments, and the present inventor has already proposed a homogeneous granulation device for waste materials, etc., in Japanese Patent Application No. 58-36249. An example in which the present invention is applied to a homogenizing device will be described in detail. Reference numeral 1 denotes a machine frame, in front of which is installed a die device 2 for uniting waste materials, etc., which is the main function of the present invention, and at the rear is a drive motor M, which is connected to the die device 2 and drive. A transmission device 3 consisting of a combination of gears is provided between the motor M and the motor M. First, the die device 2 will be explained. In this device, a pair of annular die bodies lO are combined so that they circumscribe each other.
A hole is drilled toward the center of each die body 10, and the hole is formed continuously up to the workpiece discharge portion 13 of the die body 10.

A drive shaft 15 is fitted and fixed in the center of this die body IO. Furthermore, a charging hook <18 is provided above the engaging portion of the die body 10 at the center of the front face of the die device 2. In addition, a discharge trough 19 for processed 71c waste material A is provided in front of the processed product discharge section 13 in the die body, and at least the portion from the front side to the peripheral edge of these die devices is covered by a casing 20. It is something. Next, a power transmission mechanism to the die main body 10 in such a die device 2 will be explained.

First, reference numeral 21 is an output shaft of the drive motor M, and an output gear 22 is fixed to the tip of the output shaft. This output gear 22 meshes with a relay gear phantom that is pivotally supported on the single machine frame l. Furthermore, this relay gear prisoner is @
They have a relay reduction gear that rotates in common and are integrally rotated, and the relay reduction gear meshes with a drive gear provided on one side of the drive 111115 almost below the drive gear. The drive-side gear 26 provided on the drive shaft 15 in the other die main body 10 meshes with the drive gear δ, thereby transmitting rotation in mutually opposite directions. still,
The symbol n is a symbol (-) that indicates the transmission device 3 mainly composed of these gears.

The following cooling structure is further provided for the die body IO in the waste material atomization apparatus having such a configuration. That is, the reference numeral (to) indicates a cooling medium supply hole, which is bored in the axial direction from one end of the drive shaft 15 (indicated by reference numeral 30a) and then extends radially from the axial center to the die body lO. After branching to (indicated by reference numeral 30b),
Furthermore, it extends horizontally at the outer circumference (indicated by reference numeral 30c), and then concentrates on the axis side again (
30d) and again to the discharge side (designated 30e) bored in the center of the other end of the drive shaft 15.

Such a supply hole is connected to a pipe 32 attached to a joint block 31 which also serves as a fixed bearing at the tip side of the drive shaft 15, and at the other end is connected to a pipe 34 via a joint block 33. It is connected to. At this time, for example, when the cooling medium C is supplied from the pipe 32 side, the pipes 32 and 34 are connected to each other in an endless manner because the cooling medium C is normally used in circulation. For example, if the cooling medium C is oil, an oil pan, an oil cooler serving as a heat exchanger, or the like is interposed in the middle. By the way, this cooling medium C
It goes without saying that in addition to oil, other suitable materials such as water or chlorofluorocarbon gas can be used.

The present invention is constructed as the above-described embodiment), and operates as follows to unify waste material A, which is a workpiece. First, power is supplied to the drive motor M by an appropriate switching operation, and its operation is started. At an appropriate time, the rotation of the drive motor M is transmitted from the output gear 22 attached to the output shaft 21 to the drive gear section via the relay gear holder and the relay reduction gear 24, and is further transmitted to the other drive side gear 26. is transmitted to cause the rotation of the two die bodies io. When waste material A is charged from the hopper 18 under such operating conditions, as shown in FIG. It will be absorbed. At that time, its volume is compressed, and when water or the like is mixed in, it is squeezed out and further pushed into the processed hole 12. By repeating this operation, the waste material A is pushed into the machining hole 12 one after another in a compacted state, and finally it is pushed into the machining hole 12 on the side of the workpiece discharge part 13 near the center of the die body IO. It is discharged from the inner end in the form of a stick.

At this time, since the waste material A is strongly compressed at the stage of being pushed into the processing hole 12 in the die body IO, heat of compression is generated. This heat is transferred to the die body 1O and heats it, but in the present invention, the cooling medium C is supplied to the die body 1O in response to the supply hole force of the cooling medium C. Cooling medium C
As a result, the compression heat stored in the die body 10 is heat exchanged, and the die body 10 is always maintained at a constant temperature. Therefore, even when processing waste material A, etc., there is no adverse effect due to overheating, and stable operation can be expected at all times.
