Is done. Here, when a material having a relatively high water content such as organic sludge or papermaking residue is used, the material introduced into the solidification processing device 501 is water contained in the material as it is compressed in the compression chamber 504. The pressure increases. As a result, there is a disadvantage in that the compressive force does not sufficiently act on the solid component of the material, and the material is not solidified but guided to the molding nozzle 510 in a muddy state and discharged to the outside.

  Then, the subject of this invention is providing the solidification processing apparatus which can manufacture the solidified solid substance even if it inserts the processed material with much moisture.

As shown in FIG. 4, the spiral body 2 includes a first spiral body portion 21, a second spiral body portion 22, a third spiral body portion 23, and a fourth spiral body portion 24 in order from the charging casing 11 toward the compression chamber block 15. It is formed with. FIG. 2 shows only the first to fourth spiral portions 21, 22, 23, and 24 of one spiral body 2, but the other spiral body 3 is similarly formed of the first to fourth spiral portions. ing. With reference to FIG. 2, reference is made only to one helical body 2, but the other helical body 3 has a similar configuration. The 1st thru | or 4th spiral body parts 21, 22, 23, and 24 are formed with the rotating shaft parts 21a, 22a, 23a, and 24a, and the spiral blades 21b, 22b, 23b, and 24b. The first to third spiral rotating shaft portions 21a, 22a, and 23a have hexagonal cross-sectional through holes 21c, 22c, and 23c that are inserted through the fitting portion 6a and are coaxial with the central axis. On the other hand, the rotating shaft portion 24a of the fourth spiral body has a bottomed hole 24c having a hexagonal cross section that is fitted to the tip of the fitting portion 6a and is coaxial with the central axis. A bolt hole that is continuous with the bottomed hole 24c is provided on the end surface of the rotation shaft portion 24a of the fourth spiral body. The through holes 21c, 22c, 23c are inserted into the fitting portion 6a of the rotary drive shaft 6 to attach the first to third spiral bodies 21, 22, 23, and the bottomed hole 24c is fitted to the A four-helical part 24 is attached. Bolts 28 are inserted into the bolt holes on the end face of the fourth spiral body portion 24, and the bolts 28 are screwed onto the fitting portions 6a of the rotary drive shaft 6 so that the first to fourth spiral body portions 21, 22, 23, 24 is fixed to the rotary drive shaft 6. The spiral blades 21b, 22b, 23b, 24b of the first to fourth spiral body portions 21, 22, 23, 24 of one spiral body 6 and the spiral blades of the first to fourth spiral bodies of the other spiral body 7 are in opposite directions.

  The spiral bodies 2 and 3 are formed such that the diameter of the rotation shaft portion 21a of the first spiral body portion 21 and the diameter of the rotation shaft portion 22a of the second spiral body portion 22 are increased in this order. On the other hand, the second spiral body portion 22, the third spiral body portion 23, and the fourth spiral body portion 24 have the same diameters of the rotation shaft portions 22a, 23a, and 24a. Further, the spiral bodies 2 and 3 are formed such that the pitch, which is the interval in the axial direction of the spiral blades 21b, 22b, 23b, and 24b, is reduced in this order. Furthermore, the thickness of the spiral blades 21b, 22b, 23b, 24b of the first to fourth spiral body portions 21, 22, 23, 24 is increased in this order. As a result, the volume of the chamber formed between the cylinder that is in contact with the outer periphery of each of the spiral body portions 21, 22, 23, and 24 and the outer surface of each of the spiral body portions 21, 22, 23 is set to the first spiral body portion 21. The second spiral body portion 22, the third spiral body portion 23, and the fourth spiral body portion 24 are made smaller in this order. Thereby, the said 1st spiral body part 21, the 2nd spiral body part 22, the 3rd spiral body part 23, and the 4th spiral body part 24 are formed so that the compressive force which increases in this order may act on a to-be-processed object. . The volume of the chamber corresponding to the fourth spiral body portion 24 with respect to the volume of the chamber corresponding to the first spiral body portion 21 is a ratio between 1/2 and 1/3 (hereinafter referred to as volume reduction ratio). It is formed to become. By using the spiral bodies 2 and 3 having such a volume reduction ratio, an object having a bulk specific gravity of 0.025 at the time of loading and a bulk specific gravity of about 0.45 to 0 at the time of discharging the molding nozzle 52 of the end face plate are used. It can be compressed to the extent of .5. In addition, an object to be processed having a bulk specific gravity of 0.025 at the time of charging can be compressed so that the true specific gravity is approximately between 0.6 and 1.2 when discharged from the molding nozzle 52.

  In the spiral bodies 2 and 3, the end portion on the first spiral body 21 side of the rotation shaft portion 22 a of the second spiral body is formed in a tapered shape. Thereby, when the workpiece is transferred from the first spiral body portion 21 to the second spiral body portion 22, even if the diameters of the rotary shaft portions 21a and 22a are increased, the resistance given to the workpiece is reduced. .

  In addition, the spiral bodies 2 and 3 include the first spiral body portion 21, the second spiral body portions 22 and 32, the third spiral body portion 23, and the fourth spiral body portions 24 and 34. , 23b, 24b, and 34b are formed into one winding. That is, one end of each of the spiral blades 21b, 22b, 23b, 24b, and 34b of each spiral body is at substantially the same circumferential position as the other end of the spiral blades 21b, 22b, 23b, 24b, and 34b when viewed from the axial direction. This facilitates the manufacture of the first to fourth spiral parts 21, 22, 32, 23, 24, 34, and repairs and repairs of the first to fourth spiral parts 21, 22, 32, 23, 24, 34 and This makes maintenance work such as replacement easy.

  The fourth spiral body portions 24, 34 have flat surface portions 24d, 34d that are connected to the ends of the spiral blades 24b, 34b and are formed substantially at right angles to the central axes of the rotation shaft portions 24a, 34a. By rotating and driving the flat portions 24d and 34d, the workpiece is pushed into the compression space between the boss 25 and the compression chamber block 15, and the pressure of the workpiece in the compression space is sufficiently increased. Wastes compressed to a high density are pushed out from the molding nozzle. Since the fourth helical part 24 gives the maximum compressive force among the compressive forces given by the helical parts 21, 22, 32, 23, 24, 34 to the waste, the amount of wear is larger than that of the other helical bodies. Chipping is likely to occur due to metal pieces mixed in the object to be processed.
