Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stirring blade mounting material and a stirring blade mounting method using the same. For more details,
The present invention relates to a stirring blade mounting method for mounting a stirring blade on a rotary shaft in a plurality of processing tanks formed in a processing tank by using a stirring blade mounting material including a scrap, a square pipe unit, and a stirring blade.

[0002]

2. Description of the Related Art Conventionally, stirring blades are attached to a rotary shaft by, for example, directly attaching the stirring blades to the rotary shaft by welding or by passing the rotary shaft through a square pipe having the stirring blades around it. The square pipe was attached to the rotating shaft by welding or the like.

[0003]

However, in the case where the stirring blades are respectively formed in a plurality of processing tanks formed by a plurality of partition plates by the conventional method of directly attaching the stirring blades to the rotary shaft, , I had the following problems. When the stirring shaft is formed in the partition plate and the rotary shaft is passed through and then the stirring blade is directly attached to the rotary shaft by welding or the like, the work is performed in the processing tank, but the work is extremely difficult. Efficiency decreases. In particular, when working in a narrow processing tank, the work efficiency is significantly reduced. Also, first attach the stirring blade to the rotating shaft,
When it is placed in multiple treatment tanks, it is relatively easy to attach the stirring blade to the rotary shaft, but to place the rotary blade with the stirring blade in multiple treatment tanks, it is necessary to use multiple Since the partition plate of No. 2 is cut into upper and lower parts and the rotary shaft with the stirring blades attached to the lower partition plate is pivotally supported, the upper partition plate must be welded to the lower partition plate by welding, so the number of working steps is Increase, and work efficiency also decreases. In any of the above cases, once the stirring blades have been configured in the processing tank, it is difficult to remove them, so if the stirring blades or part of the rotating shaft is corroded or damaged,
It is not economical because the entire apparatus using the rotary shaft equipped with the stirring blade cannot be used. In any of the above cases, the rotation shaft is bent and the shaft shake occurs due to the direct attachment of the stirring blades to the rotation shaft, which increases the load on the motor. Especially, the influence is remarkable for the rotary shaft for long span.

On the other hand, in the method of attaching the square pipe having the stirring blades to the rotary shaft, the stirring blades are not directly mounted to the rotary shaft, so that the influence of the shaft shake due to the bending of the rotary shaft is relatively small, and When stirrer blades are formed in a plurality of processing tanks formed by a plurality of partition plates, shaft holes are formed in the partition plates of the respective processing tanks, and hollow holes of square pipes are formed in the shaft holes. After matching the parts, the rotary shaft is sequentially passed through the shaft hole and the hollow portion of the square pipe, and both ends of the square pipe may be attached to the rotary shaft by welding or the like. The work in the treatment tank is much less than when it is attached, and it is not necessary to cut the partition plate into two pieces, but in this case as well, once the stirring blades are configured in the treatment tank, the Outside Since it is difficult, there is a problem that is just as economical as when mounting the stirring blade directly to the rotating shaft.

In view of such circumstances, the present invention makes it easy to attach and remove the stirring blades to and from the rotary shaft in each processing tank, and the rotation shaft hardly shakes. It is an object of the present invention to provide a stirring blade mounting material that can be easily manufactured according to the size.

[0006]

The stirring blade mounting material of the present invention is formed on each of the plurality of partition plates in a plurality of processing tanks formed by a plurality of partition plates formed in the processing tank. A stirrer blade mounting member that is locked to a rotary shaft that is axially supported by a shaft hole, an end material having a flange portion and a cylindrical portion, a square pipe unit, and an inclination with respect to the longitudinal direction of the square pipe unit. And a stirring blade attached to the peripheral side surface of the square pipe unit, and the cylindrical portion of the end material is fitted to both ends in the longitudinal direction of the square pipe unit.

Further, the stirring blade mounting method using the stirring blade mounting material of the present invention is such that the stirring blade mounting material is installed in each processing tank at a position concentric with the shaft hole formed in the partition plate of each processing tank. It is characterized in that the hole of the flange portion of the mill ends is located and the rotary shaft is sequentially penetrated through the shaft hole of the partition plate and the hole of the mill ends of the stirring blade mounting material.

The treatment tank referred to in the present invention is an apparatus used for crushing, mixing, separating, transporting, etc. various substances, and its use is not particularly limited, and it is used in all fields. A typical example of use is a garbage disposal tank,
There are crushed stone and sand separation septic tank, powder and grain mixing tank, etc.

[0009]

In the stirring blade mounting material of the present invention, the shaft hole formed in the partition plate of each processing tank is aligned with the hole in the flange portion of the end material of the stirring blade mounting material, and the rotary shaft is the shaft hole. The stirring blade mounting material can be attached to the rotating shaft in each processing tank by simply sequentially penetrating through the holes of the end material of the stirring blade mounting material, and conversely, the rotating shaft can be replaced by the shaft hole and the stirring blade mounting material. Since the stirring blade mounting material can be removed from the rotary shaft simply by sequentially pulling out the stirring blade mounting material from the end material hole, it is easy to mount and remove the stirring blade mounting material on the rotary shaft in each processing tank.

Further, since the stirring blade is attached to the square pipe unit and is not directly attached to the rotating shaft, the bending of the rotating shaft due to the attachment of the stirring blade is hardly caused, so that the rotating shaft is hardly shaken. Further, in the stirring blade attaching material of the present invention, the stirring blade is attached to the square pipe unit, and the cylindrical portion of the end material including the flange portion and the cylindrical portion is fitted to both ends in the longitudinal direction of the square pipe unit. Since the structure is simple, and its size is determined by the size of the square pipe unit, it is possible to easily manufacture the stirring blade attachment material according to the size of each processing tank.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 shows a stirring blade mounting member A which is an embodiment of the present invention.
Is shown. The stirring blade mounting material A is used by being attached to the rotary shaft 10 in a plurality of processing tanks formed by a plurality of partition plates configured in the garbage processing tank. It is composed of unit 2. In addition,
A bolt hole 31 for inserting a rod bolt 3 described later is formed at an appropriate position of the rotary shaft 10 in a direction perpendicular to the axial direction (see FIG. 2), and the rotary shaft 10 has a partition plate. It is pivotally supported in shaft holes 43 and 44 formed in 41 and 42 (see FIG. 5).

The end material 1 has a flange portion as shown in FIG.
It is composed of 11 and a cylindrical portion 12. The flange portion 11 is composed of a concave member 11a having a hole formed in the center thereof which is slightly larger than the outer diameter of the rotary shaft 10 and a disk 11b having a hole having substantially the same diameter as the hole of the concave member 11a formed in the center thereof. It is configured. Then, the disc 11b is fitted into the concave portion of the concave member 11a,
As shown in FIG. 3, the concave member 11a is formed by a plurality of screws 13.
Is fastened to. In addition, the screw 13 is slightly longer than the thickness of the flange portion 11 of the end material 1 in order to use it when the square pipe unit 2 described later is locked to the end material 1. Further, since the concave member 11a is a portion that comes into contact with a bearing attached to a shaft hole formed in the partition plate (see FIG. 5) and is hit by raw dust, as will be described later,
It is necessary to have abrasion resistance, chemical resistance, and rust resistance. In this example, the product name "MC nylon" manufactured by Nippon Polypenco Co., Ltd. was used. Since the circular plate 11b is a portion that is exposed to raw dust, it must have chemical resistance and be resistant to rust.
In this example, stainless steel was used.

The cylindrical portion 12 is made of stainless steel pipe,
The inner diameter is substantially the same as the holes formed in the concave member 11a and the circular plate 11b of the flange portion 11. Then, one end of the cylindrical portion 12 is connected to the disc 11 of the flange portion 11 so that the hole formed in the flange portion 11 and the hollow portion of the cylindrical portion 12 communicate with each other.
The flange portion 11 and the cylindrical portion 12 are integrated by abutting on b. In this embodiment, the flange portion 11 and the cylindrical portion 12 are integrated by welding one end of the cylindrical portion 12 to the circular plate 11b of the flange portion 11.
The two may be integrally molded, the concave member 11a may be fitted to the disc 11b, and the concave member 11a may be fastened to the concave member 11a by a plurality of screws 13. In addition, a bolt hole 32 for inserting a rod bolt 3 described later is formed in an appropriate portion of the cylindrical portion 12 in a direction perpendicular to the axial direction (see FIG. 2). In addition, it is preferable to form a taper at both ends of the end material 1 composed of the flange portion 11 and the cylindrical portion 12 in order to prevent the rotary shaft 10 from being caught (see FIG. 7).

The square pipe unit 2 is a regular square column having a hollow portion of a regular square column formed therein, and its length is determined by the size of the processing tank. Further, bolt holes 33 into which the rod bolts 3 to be described later are inserted are formed at appropriate positions of the square pipe unit 2 in a direction perpendicular to the longitudinal direction thereof (see FIG. 2). In this embodiment, a hollow regular square column is used as the square pipe unit 2, but the square pipe unit 2 does not necessarily have to be a regular square column, and may be a regular triangular column, a regular pentagonal column or the like.

The stirring blades 21, 22, 23 are rectangular plate members, and are attached to the three rectangular side surfaces around the square pipe unit 2 by welding while being inclined with respect to the longitudinal direction of the square pipe unit 2. ing. In the present embodiment, the stirring blades 21, 22, 23 are attached to three rectangular side surfaces of the four rectangular side surfaces of the square pipe unit 2, respectively, but the stirring blades may be attached to all four rectangular side surfaces, Further, it is possible to attach a plurality of stirring blades to one rectangular side surface. The inclination angle of attachment of the stirring blades 21, 22, 23 to the rectangular side surface of the square pipe unit 2 and the number of stirring blades attached to the rectangular side surface of the square pipe unit 2 are determined by the processing in which the stirring blade mounting member A is used. It is decided by comprehensively considering the size of the tank, the driving force of the motor, and the like. Further, since the square pipe unit 2 and the stirring blades 21, 22, and 23 are portions for stirring raw garbage, they need to have chemical resistance and be resistant to rust. In this embodiment, stainless steel was used.

Next, a method of forming the stirring blade mounting material A by the end material 1 and the square pipe unit 2 and mounting the stirring blade mounting material A on the rotary shaft 10 will be described. First, as shown in FIG. 4, the cylindrical portions 12 of the end material 1 are fitted into the regular square columnar hollow portions at both ends in the longitudinal direction of the square pipe unit 2. At this time, as described above, since the screws 13 are slightly longer than the thickness of the flange portion 11 of the end material 1, the four screws 13 are attached to the regular squares at both ends in the longitudinal direction of the square pipe unit 2. It can be configured so that the four corners of the columnar hollow portion can be hooked. Therefore, the square pipe unit 2 and the end material 1 are integrated to form the stirring blade attachment material A.

Next, as shown in FIG. 2, the rotary shaft 10 is penetrated into the end material 1 of the stirring blade mounting material A, and the rotary shaft 10, the square pipe unit 2 and the cylindrical portion 12 of the end material 1 are respectively provided. The formed bolt holes 31, 32, 33 are aligned and the bolt holes 31, 3
The rod bolts 3 are inserted into 2, 33 and fastened with nuts 4, and the square pipe unit 2, the cylindrical portion 12 of the end material 1 and the rotary shaft 10 are integrated to attach the stirring blade mounting material A to the rotary shaft 10. .

Next, the case where the stirring blade mounting material A is actually mounted in the processing tank will be described. As shown in FIG.
When one processing tank is configured by the partition plate 41 (hereinafter, left partition plate 41) and the partition plate 42 (hereinafter, right partition plate 42), and when the stirring blade mounting material A is mounted in the processing tank explain.

A shaft hole 43 is formed in the left partition plate 41, and a shaft hole 44 is formed in the right partition plate 42.
A bearing 45 is fitted in the shaft hole 43 of the left partition plate 41, and the bearing 45 is fastened to the left partition plate 41 by a plurality of screws 47 as shown in FIG. Similarly, right partition
A bearing 46 is fitted into the shaft hole 44 of the 42, and the bearing 46
Are fastened to the right partition plate 42 by a plurality of screws 48. Grooves are formed on the inner peripheral surfaces of the bearings 45 and 46, and oil seals 49 and 50 are mounted in the grooves.

First, the left partition plate 41 and the right partition plate 42 in the processing tank
And the stirring blade mounting material A is disposed between them and the holes of the end material 1 of the stirring blade mounting material A are substantially aligned with the holes of the bearings 45 and 46. Next, the rotary shaft 10 is penetrated so that the holes of the bearings 45 and 46 and the hole of the end material 1 of the stirring blade mounting member A communicate with each other, and as described above, the stirring blade mounting member A is fixed by the rod bolt 3 and the nut 4.
Is attached to the rotary shaft 10.

Next, another embodiment of the stirring blade attachment material will be described. FIG. 7 shows a stirring blade mounting member B which is an embodiment of the present invention. The stirring blade mounting material B is mainly used for a large garbage disposal tank, and its configuration is
It is substantially the same as the agitating blade attachment material A described above, and is composed of an end material 1 and a square pipe unit 2.

The end material 1 is composed of a flange portion 11 and a cylindrical portion 12, and the flange portion 11 is composed of a concave member 11a and a disc 11b as in the case of the stirring blade mounting material A.
The cylindrical portion 12 is formed to have a larger wall thickness than that of the cylindrical portion 12 of the stirring blade mounting material A because the cross-section of the square pipe unit 2 described later is large, but other than that, the stirring blade mounting material is formed. It is almost the same as the case of A. The flange 11
Further, a taper is formed at one end of the cylindrical portion 12 in order to prevent the rotation shaft 10 from being caught.

The square pipe unit 2 has a larger cross section than the square pipe unit 2 of the stirring blade mounting member A so that a large stirring blade can be attached.

The stirrer blade mounting member B is constituted by the end material 1 and the square pipe unit 2, and the stirrer blade mounting member B is used as a rotary shaft.
The method of attaching to the stirring blade 10 is almost the same as the case of the stirring blade mounting material A, but as shown in FIG. 8, the cross section of the square pipe unit 2 is larger than that of the stirring blade mounting material A. As in the case of the mounting member A, it is not possible to configure the four screws 13 so that the four corners of the regular square columnar hollow portion at both ends in the longitudinal direction of the square pipe unit 2 can be hooked (see FIG. 4). Therefore, as shown in FIG. 7, in the vicinity of both ends of the square pipe unit 2, the rod bolt 3 is fitted through the square pipe unit 2, the cylindrical portion 12 of the end material 1, and the rotary shaft 10, and the nut 4 is tightened. , Attach the stirring blade attachment material B to the rotary shaft 10.

As described above, with the stirring blade mounting materials A and B of this embodiment, it is easy to mount and dismount the stirring blade mounting materials A and B on the rotary shaft 10 in the processing tank, so that the working efficiency is improved. In addition to the improvement, it is possible to easily repair the stirring blade mounting members A and B. Also,
The stirring blades 21, 22, 23 are attached to the square pipe unit 2, and the cylindrical portion 12 of the end material 1 is fitted to both ends of the square pipe unit 2 in the longitudinal direction. Since the shake hardly occurs, the driving force of the motor can be efficiently transmitted. Moreover, since the stirring blade mounting materials A and B having arbitrary sizes can be easily manufactured, the stirring blade mounting materials A and B can be used according to various processing tanks. Furthermore, since the stirring blade mounting member B can be attached to a large stirring blade, it can be used in a large processing tank. The stirring blade mounting materials A and B of this embodiment can be used for both the vertical processing tank and the horizontal processing tank.
