Definitions
- the present invention relates to a flange joint for connecting a shaft and a drive part of a molten metal stirrer used for degassing a molten metal such as aluminum.
- Patent Document 1 describes a molten aluminum stirring jig in which a stirring shaft is connected to a motor and a stirring blade is provided at the lower end of the shaft, and the motor is driven to immerse the molten aluminum in the molten aluminum. The stirring blade rotates and the molten metal can be stirred.
- Patent Document 2 discloses a rotating body for molten metal agitation in which a shaft is connected to a rotation shaft of a rotation drive mechanism and a rotor is provided at the lower end of the shaft, and by driving the rotation drive mechanism, The rotor immersed in the molten metal rotates and the molten metal can be stirred.
- a shaft (stirring shaft) and a rotation drive mechanism (motor) are connected using a flange joint or the like.
- the shaft and the flange joint are connected by, for example, screwing and fastening them to each other (paragraph [0024] in Patent Document 2).
- the shaft is often made of ceramics in consideration of heat resistance, corrosion resistance and wear resistance
- the flange joint is often made of metal in consideration of durability.
- both screw portions may gradually bite and cannot be removed as the rotor rotates. When this happens, maintenance is no longer possible, and attempts to remove it have led to damage.
- an object of the present invention is to provide a flange joint for a molten metal stirrer that can be easily detached from a shaft even when used for a long time or for a long period of time and does not cause the shaft to be damaged.
- the flange joint for a molten metal stirrer of the present invention includes a cylindrical support portion that can sandwich the upper peripheral surface of the shaft of the molten metal stirrer, and a protruding portion that projects horizontally from the upper end of the support portion. It is characterized by having a left and right split shape with.
- the flange joint for molten metal stirrer of the present invention is divided into a left and right split shape that can sandwich the shaft, so that the threaded portion is not easily caught by the difference in thermal expansion of both as in the case of threading. Can be removed. Further, since the shaft is not loaded when it is removed, there is no possibility of the shaft being damaged.
- FIG. 1 It is sectional drawing which showed the degassing apparatus using the flange joint for molten metal stirring bodies of one Embodiment of this invention. It is the disassembled perspective view which showed the flange joint of FIG. It is the perspective view which showed the half part of the flange joint of FIG.
- FIG. 2 is an enlarged sectional view showing the vicinity of a flange joint in FIG. 1.
- the flange joint 1 for a molten metal stirrer connects a molten metal stirrer 2 and a drive unit 3 that rotates the molten metal stirrer 2.
- the stirring body 2 includes a shaft 21 and a stirring blade 22, and a conventional one can be used.
- the shaft 21 is formed in a cylindrical shape, and a disc-like stirring blade 22 is provided on the lower end side thereof.
- These are not particularly limited, and those formed from materials such as silicon nitride ceramics, sialon ceramics, silicon carbide ceramics, carbon ceramics, carbon, and aluminum titanate can be used.
- the flange joint 1 is made of a metal such as stainless steel such as SUS304 or carbon steel such as S25C, and is formed so as to be divided into right and left parts 1a and 1b as shown in FIG.
- the flange joint 1 can be combined.
- the right side portion 1a and the left side portion 1b are formed in the same shape.
- the right side portion 1a (left side portion 1b) includes a semi-cylindrical portion 11a (11b) extending in the vertical direction and a semicircular portion 12a (12b) extending horizontally outward from the upper end portion thereof. And a rectangular plate-like portion 13a (13b) projecting outward from both longitudinal ends of the semicylindrical portion 11a (11b) along the end of the semicircular portion 12a (12b) is there.
- the rectangular joint 13a of the right side 1a and the rectangular plate 13b of the left side 1b are overlapped and joined to form the flange joint 1 as shown in FIG.
- the cylindrical portion 11a (11b) becomes the cylindrical support portion 11
- the semicircular portion 12a (12b) becomes the circular protruding portion 12
- the rectangular plate portion 13a (13b) and the rectangular plate-like coupling portion 13 Become.
- the support portion 11 sandwiches the upper end side peripheral surface of the shaft 21 so that the shaft 21 can be fixed. Therefore, the inner diameter of the support portion 11 is preferably formed to be substantially the same as or larger than the outer diameter of the shaft 21.
- a plurality of circular holes 14 are provided in the circumferential direction so that they can be connected to the flange joint 31 of the driving portion 3.
- a plurality of circular holes 15 are provided in the vertical direction.
- the right side portion 1 a and the left side portion 1 b face each other, and the rectangular plate-like portions 13 a (13 b) are overlapped with each other.
- Fastening members such as screws and bolts are inserted and fastened so that they can be coupled.
- the drive unit 3 is provided with a motor or the like so that the stirring body 2 can be rotated.
- the flange joint 31 is formed.
- a circular hole 32 is provided at a position corresponding to the circular hole 14 of the overhanging portion 12, and this circular hole 32 faces the circular hole 14 of the overhanging portion 12.
- a fastening member such as a screw or a bolt is inserted therethrough and fastened so that the flange joints 1 and 31 can be joined together.
- the flange joint 1 for a molten metal stirrer has no fear that the screw part will not be caught by a difference in thermal expansion as in the case of threading even when the molten metal is degassed for a long time or for a long time, Moreover, since the load is not applied to the shaft 21 when removing, there is no possibility that the shaft 21 is damaged.
- the right side portion 1a and the left side portion 1b have the same shape.
- the present invention is not limited to this.
- the configuration aspect of the above embodiment is not intended to limit the present invention, and can be changed as long as the technical purpose is common, and the present invention includes such a change.
