Field of the Invention The present invention relates to an apparatus for mixing a solidifying material such as cement with a raw material such as clay to obtain a solid mass in a granular form. The granules are used for embedding in the sea, for increasing the volume of various kinds, or for concrete aggregate and the like. 2. Description of the Related Art Raw materials such as clay waste and construction waste from the ceramic industry cannot be used as such as landfills along the coast or concrete aggregates, so it is necessary to solidify the raw materials with cement or a coagulant. Conventionally, there is a twin-screw kneader that solidifies and forms agglomerates while kneading a raw material and a solidified material by rotating a pair of rotating shafts facing each other and rotating a number of blades attached to the rotating shafts. It was being used. according to this,
Agglomerates having a uniform particle size are granulated, but the material to be kneaded often adheres to the wall material and solidifies, and the blades come into contact with the adhered solid and damage the blade and the wall material. Therefore, troublesome operations such as removal of the adhered solids from the wall material and replacement of the blades are frequently required. [0003] Accordingly, the present invention provides an apparatus for manufacturing agglomerates of the type described above, which prevents the blades and the wall material from being damaged by preventing adhesion of the agglomerates to the wall material. At the same time, it is possible to eliminate the troublesome work of removing the adhered solids from the wall material and replacing the blade. [0004] For this reason, the present invention provides a rotary
The shafts are arranged in a pair in the horizontal direction and rotated counter to each other.
The raw material and the solidified material are kneaded by the rotation of a large number of attached
In a horizontal biaxial device for solidifying and molding granules ,
The wall material which the kneaded material at the outer peripheral position of the lower half substantially sliding contact of rotational path so as to form an elastic material such as rubber, supports the lower wall member so as to be flexible displacement, vertical between the pair of rotating shaft
Determine the position of the lower wall material at the intersection of the bisector,
Raise with a ridge from below along the hand direction, and face the opposing wings.
Agglomerates supported slightly below the lower intersection of the root rotation trajectory
It is a body manufacturing device. [0005] With the rotation of the blades, the raw material is kneaded with a solidifying material such as cement and gradually solidified, and is rolled between the tip of the blade and the wall material to be formed into granules and discharged. At this time, when the material to be kneaded or the agglomerates are pressed against the wall material more than necessary by being pressed by the blade, the wall material is bent outward, and then the pressing is immediately released by the rotational displacement of the blade, whereby the wall surface is released. Since the material is elastically restored inside, the material to be kneaded does not adhere to the wall material, and the wall material and the blades are prevented from being damaged by the agglomerates. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to an embodiment shown in the drawings. The mass production apparatus shown in FIG. 1 has a pair of rotating shafts 11 and 12 arranged in parallel in the lateral direction and gears 21 and
2 and one of the rotary shafts 11 is connected to the geared motor 3 to form a drive shaft. Rotating shaft 11, 1
The reference numeral 2 indicates that the front part is slightly inclined downward and is supported on the body 4.
In addition, a chute 91 of the filter cake 9 of the clay dehydrated by the filter is connected to a rear portion of the body 4. The rotating shafts 11 and 12 are provided with a large number of blades 5 bent toward the tips.
As shown in FIG. 2, the blades fixed to the other rotating shaft are arranged so as to bite between the front and rear, and as shown in FIG.
Is brought close to the other rotation axis. The blade 5
Protrudes and is fixed to the boss 50, and the boss 50 is
12 is fitted and fixed. Further, the rotation locus 51 of the blade 5 is
A wall material 6 with which the material to be kneaded slides is provided at an outer peripheral position of the wall member, and the wall material 6 is formed of rubber. The wall material 6
Both sides are fixed to the inner surface of the body 4 by bolts 7 and, as shown in FIG.
Is provided at the center inner bottom of the body 4 and the wall material 6 is mounted thereon. That is, the position of the bottom of the wall member 6 which is the intersection of the perpendicular bisector between the pair of rotating shafts 11 and 12 is supported by projecting slightly below the lower intersection 52 of the rotation locus of the opposing blade. are doing. According to this, the wall material 6 is supported by the bolt 7 stopper and the protruding band 41, and the other lower half is not supported and can be deformed. In addition,
The projecting band 41 and the bottom of the wall material 6 may be fixed with bolts or the like. Reference numerals 47 denote stoppers provided at both corners of the fuselage 4 to prevent the wall member 6 from bending extremely outward. Further, a discharge chute 4 provided in communication with the body 4 is provided.
A discharge hole 63 communicating with 5 is provided through the bottom surface of the front part of the wall material 6. According to this embodiment, the clay cake 9 and the cement 8 put into the chute 91 are sheared while being kneaded between the blades 5 and the wall material 6 by the opposing rotation of the blades 5 driven by the motor 3. It becomes lumpy gradually. Further, by the rotation of the blade 5, it is rolled between the blade 5 and the wall material 6 to be solidified to form the agglomerates 90, fall into the inclined discharge hole 63, and discharged from the discharge chute 45. The resulting aggregate 90 has a diameter whose diameter is the distance between the blade 5 and the wall material 6. At this time, the material to be kneaded or the agglomerates may be pressed more than necessary against the wall material by being pressed by the blades. However, since the wall material 6 is made of rubber, as shown in FIG.
Since the wall material 6 is bent outward and the inwardly projected state is eliminated, collision with the agglomerates 90 is avoided, and the blades 5 are not damaged. Note that extreme outward bending of the wall material 6 is prevented by the stopper 47. Then, as soon as the blades are disengaged due to the rotational displacement of the continuous blades and the pressure is released, the wall material is elastically restored to the inside, so that the material to be kneaded or the aggregates 90 do not adhere to the wall material. It is. Even if the material to be kneaded or the agglomerates 90 adhere to the wall material 6, they are scraped off by the next rotating blade 5. Therefore, the wall material 6 and the blades 5 are prevented from being damaged by the agglomerates 90. The present invention is not limited to the embodiment.
For example, any material may be used as long as the raw material and the solidified material are kneaded by the rotation of a large number of blades attached to the rotating shaft and solidified and formed into agglomerates, and the number of rotating shafts, or the shape and number of blades, and the number of blades The mounting configuration does not matter. In addition, the type of raw material and solidified material,
The material is not limited. Further, the material of the wall material disposed at the outer peripheral position of the blade may be an elastic material, and may be a flexible plastic or the like. The arrangement shape and the supporting configuration of the wall material are appropriate, and any material may be used as long as the material to be kneaded or the agglomerate can be kneaded and granulated by the rotation of the blade and can be displaced. Therefore, in the case of a vertical device, the wall material also has a vertical cylindrical shape, but an inclined horizontal type is optimal for slowly kneading and granulating, and in this case, substantially below the rotation locus of the blade. The lower wall material at the half outer peripheral position may be formed of an elastic material such as rubber. The use of the obtained agglomerates is arbitrary. According to the present invention, the wall material can be flexibly displaced.
When the material to be kneaded or the agglomerate is pressed against the wall material more than necessary by the blade, the wall material of the elastic material bends outward to prevent breakage of the blade, and good mass granules for subsequent material to be mixed since it is scraped off by the blade rather name may adhere to the wall surface member, moreover horizontal twin-screw type device can be obtained immediately wall member is elastically restored inwardly It is.
