Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a continuous kneader for kneading thermosetting resin, various foods, chemicals, fly ash from an incinerator, and the like.
[0002]
[Prior art]
As a kneader for continuously stirring and kneading raw materials such as powder, a biaxial kneader is generally used, and the biaxial kneader is disclosed in JP-A-11-267481 (Patent 1) and JP-A-2000. -455 (publication 2) and the like, and as shown in FIGS. 10 and 11, the kneading shaft 2 in the cylindrical axis direction is passed through the horizontal cylindrical casing 1 and processed from one end of the casing 1 Generally, a configuration is used in which an article is fed into the casing 1, kneaded by the kneading shaft 2, and discharged from the other end of the casing 1.
[0003]
In these continuous kneaders, in order to obtain a product of high quality and stable properties, after the operation of the kneading machine, in order to maintain the same performance even in the next operation, a feed screw, a paddle, etc. of the kneading shaft 2 are used. It is essential to check and clean.
[0004]
When performing such inspection and cleaning, the kneading shaft 2 is generally opened, and as the opening means, the publication 1 discloses that the casing 1 is moved up and down on a horizontal plane as shown in FIG. A technique is disclosed in which the upper and lower casings 1a and 1b are swingable in the vertical direction, and Japanese Laid-Open Patent Publication No. 2 discloses a technique in which the lower casing 1b has a double-opening shape as shown in FIG. Yes. Further, the technology described in the publication 2 allows the side surface of the upper casing 1a to be opened.
[0005]
[Problems to be solved by the invention]
This type of continuous kneader is often installed on a solid ground and does not have a work space below. In addition, it is complicated and inconvenient to open the lower surface of the casing and perform the work upward from below during inspection and cleaning. For this reason, the technique described in publication 2 has poor workability because the lower casing opens downward. In addition, inspection / cleaning with the side surface of the upper casing opened is more complicated and less workable than that with the casing upper surface described in Patent Publication 1 open, and the opening location as in the technique described in Patent Publication 2 is not sufficient. Even if the number is plural, a great improvement in workability cannot be expected.
[0006]
By the way, as shown in FIG. 10, what opens the upper casing 1a by swinging upward with its side edge as an axis requires a space for the opened upper casing 1a to swing backward. Moreover, when installing this continuous kneader in a production line, the opening direction of the upper casing 1a is determined by the line specifications. For this reason, unless the installation location such as the line specification is determined, the opening direction of the upper casing 1a cannot be determined, and the manufacture of the continuous kneader cannot be completed. Moreover, when transferring the existing continuous kneader, there is a restriction that it can only be transferred to a place where the opening direction of the upper casing 1a matches.
[0007]
This invention makes it the 1st subject to aim at the improvement of installation nature in the above-mentioned situation, and makes it the 2nd subject to improve workability, such as inspection and cleaning.
[0008]
[Means for Solving the Problems]
In order to achieve the first object, according to the present invention, the upper casing is first swingable to be opened. This is because the upward opening is easy to inspect and clean.
[0009]
Next, the upper casing is made swingable upward on both sides around the other side. Thus, if it can open from both sides, there will be few restrictions on an installation location.
[0010]
In order to achieve the second object, the present invention, first, similarly, allows the upper casing to swing and be opened, and then divides the upper casing into a plurality of parts in the length direction. The casing can be swung upward about one side as an axis.
[0011]
By dividing the open parts in this way, only the parts that need to be inspected and cleaned can be opened, and the workability is excellent. This second solution can be used in combination with the first solution.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
As an embodiment of the invention for achieving the first object, a kneading shaft in a cylindrical axis direction is passed through a horizontal cylindrical casing, and an object to be processed is fed into the casing from one end of the casing, In a continuous kneader that is kneaded by a kneading shaft and discharged from the other end of the casing, the casing is divided into upper and lower casings in a horizontal plane, and the upper casing has both sides on the other side. It is possible to adopt a configuration that can swing upward about the axis.
[0013]
As a specific configuration for enabling the upper casing to be opened from both sides, both sides of the upper casing are connected to both sides of the lower casing so as to be able to rotate via respective rotating shafts, and the connecting portion connects both casings. Use a structure that can be separated.
[0014]
As an embodiment of the invention for achieving the second problem, in the above-described casing open continuous kneader, the casing is divided into upper and lower casings in a horizontal plane, and an upper casing and a lower casing are provided. It is possible to adopt a configuration in which the casing is divided into a plurality of parts in the length direction, and each of the divided casings can swing upward with the one side as an axis.
[0015]
In this configuration, if each of the divided casings has a single swinging shaft extending over all the divided blocks, and each of the divided blocks is fastened from both ends of the swinging shaft, the fastening of the single swinging shaft is achieved. Thus, all the divided casings can be fastened, and the workability is good and the structure is simple.
[0016]
Embodiment which achieves this 2nd subject can be used together with each above-mentioned embodiment which achieves the 1st subject.
[0017]
In each of the above-described embodiments, when the upper casing comes into contact with the lower casing when the upper casing is released from swinging, the swing release structure can be simplified by restricting the swing opening. This is advantageous in terms of cost. In addition, if the upper casing is composed of a top plate and a liner fixed to the inner surface thereof, and the lower casing is also composed of a bottom plate and a liner fixed to the inner surface thereof, only the worn liner can be replaced. This is advantageous.
[0018]
【Example】
An embodiment is shown in FIGS. 1 and 2, in which 11 is a casing having a supply port 14 at one upper end and a discharge port 15 at the lower end, and an upper casing having a horizontal plane including its cylinder axis. 12 and a lower casing 13. Two kneading shafts 16 are provided in parallel in the casing 11, and a large number of kneading paddles 17 are externally fitted to the kneading shafts 16 with different phases. End plates 25 and 26 are provided before and after the casing 11, and a seal member and a bearing for the kneading shaft 16 are provided in the end plates.
[0019]
An arm 18 is provided on both sides of the upper casing 12, and a fixed arm 19 is provided on each side of the lower casing 13, and both the arms 18 and 19 are connected by a rotating shaft 20. The two kneading shafts 16, 16, the rotating shaft 20, and the dividing surface of the casing 11 are on the same plane.
[0020]
In this embodiment, an object to be kneaded (object to be processed) a is supplied from the supply port 14 and transferred to the discharge port 15 while kneading the object to be kneaded a by the rotation of the kneading paddle 17 to discharge the product b. .
[0021]
When cleaning, inspection, or maintenance becomes necessary, the rotary shaft 20 on one side is removed, and the upper casing 12 is rotated upward as shown by the chain line in FIG. 1 with the rotary shaft 20 on the other side as the center (axis). The upper part of the kneading shaft 16 is opened.
[0022]
At this time, since the rotating shaft 20 is provided on both sides of the casing 11 in this embodiment, the upper casing 12 can be rotated to either side. Move it. Thereby, work labor and time can be shortened. For example, when the paddle 17 is removed from the kneading shaft 16, since the workpiece is attached, the paddle 17 is hit with a mallet or the like, but the rotation direction of the upper casing 12 depends on whether the operator is right-handed or left-handed. You can easily select and work. Further, it becomes difficult to be restricted by the installation location (layout), and the manufacture of the apparatus can be completed before the installation location is determined.
[0023]
FIGS. 3 and 4 show another embodiment. In this embodiment, the upper casing 12 is divided in the axial direction of the kneading shaft 16, and in the illustrated example, the front block 21 and the center are arranged from the supply port 14 side. The block 22 and the rear block 23 are divided into three. This division number is arbitrary. A rotation arm 18 is provided on one side of each block, and is engaged with a lower fixed arm 19 via a rotation shaft 20. In addition, a flange 24 is formed at the end (divided surface) of each block, and can be coupled by a coupling member such as a bolt or a cotter (not shown). In addition, each block or each block and the upper casing 12 is sealed by filling with a sealant or attaching a rubber seal.
[0024]
In this embodiment, only the necessary blocks among the blocks 21, 22, 23 can be rotated to open the upper portion of the kneading shaft 16. At this time, the casing 11 is generally provided with a supply port 14 at one upper end, and in order to rotate the upper casing 12, a pipe, a chute or the like connected to the supply port 14 must be removed. However, in this embodiment, the front block 21 with the supply port 14 is kept closed, the connecting means of the flanges 24 of the other blocks 22 and 23 are removed, and only the necessary blocks need to be rotated. .
[0025]
Incidentally, a general inspection method is performed by providing an inspection port in the casing 11, but the inspection port cannot sufficiently open the upper portion of the kneading shaft 16 and is difficult to work (see Japanese Patent Publication No. 2).
[0026]
In this embodiment, if the arms 18 and 19 are provided on the opposite side of the casing 11 as in the embodiment of FIGS. 1 and 2, each block can be rotated to the left or right (see FIG. 5). ).
[0027]
Further, another embodiment is shown in FIGS. 5 and 6. In this embodiment, in the embodiment of FIGS. 3 and 4, each block can be turned to the left or right side, and on both sides of the casing 11, A rotation shaft 27 having a length substantially the same as the entire length of the casing 11 is provided, and both ends of the rotation shaft 27 are threaded and tightened with nuts 28 to thereby make the front block 21, the central block 22, and the rear block 23. Are combined. For this reason, the flange 24 shown in FIG. 4 becomes unnecessary.
[0028]
FIG. 7 to FIG. 9 show still another embodiment. In this embodiment, the upper casing 12 is made up of front, center, and rear blocks 31, 32, 33 made of a liner, and a top plate 31a on the top. , 32a, 33a, and the top plate is divided at positions corresponding to the respective blocks. The lower casing 13 includes front, center, and rear blocks 34, 35, and 36, which are also made of a liner, and a bottom plate 37 at the bottom.
[0029]
The top plates 31 a, 32 a, 33 a are wider than the blocks 31, 32, 33, and protrusions 38 are formed on both sides, and each block is fitted between the protrusions 38. Further, the rotating arm 18 is suspended from the protrusion 38. The bottom plate 37 is also wider than the blocks 34, 35, and 36, and protrusions 39 are formed on both sides. Each block is fitted between the protrusions 39. That is, the interval between the protrusions 38 is substantially equal to the width of each block 31, 32, 33, and the centering is almost completed by fitting each block. Similarly, the interval between the protrusions 39 is substantially equal to the width of each block 34, 35, 36, and the centering is almost completed by fitting each block. A fixed arm 19 is erected on the protrusion 39.
[0030]
In this embodiment, as shown in FIG. 7, when part or all of the upper casing 12 divided into three parts is rotated, the top plates 31a, 32a, 33a and the bottom plate 37 are engaged (contacted), Further rotation is restricted. For this reason, it is not necessary to provide a stopper.
[0031]
The configuration of the upper and lower casings 11 and 12 of this embodiment, that is, the configuration of the top plate and the block, can also be adopted for the non-divided one shown in FIG.
[0032]
In each embodiment, the fixed arm 19 is attached to the lower casing 13. However, the fixed arm 19 can be fixed to a frame of a kneader or the like. The upper casing 12 can be turned by using an overhead crane or installing a turning hydraulic cylinder.
[0033]
【The invention's effect】
As described above, according to the present invention, the upper casing can be swung upward on both sides of the upper casing as axes, so that the work such as inspection and cleaning can be easily performed, and restrictions on the installation place are reduced.
[0034]
In addition, since the upper casing is divided so that the upper part of the kneading shaft can be partially opened, only parts that require inspection and cleaning can be opened, and the workability is improved.
