Technical Field

Background

If it is desired to perform agitation, such as mixing, in a pressure vessel, it is common to provide fan blades in the pressure vessel. The motor driving the fan blades can be installed outside the pressure vessel, referring to fig. 1, the fan blades F are installed inside the pressure vessel T, the rotating shaft a of the fan blades F extends to the outside of the pressure vessel T, and the motor M is installed on the outer wall surface of the pressure vessel T and covered by the cover C. In addition, the motor for driving the fan blades may be installed inside the pressure container, and referring to fig. 2, the fan blades F are installed inside the pressure container T, and the motor M for driving the fan blades F is also installed inside the pressure container T.

In the structure of fig. 1, since the rotation shaft a of the motor M must extend from the outside of the pressure vessel T into the inside of the pressure vessel T, an opening must be formed in the wall surface of the pressure vessel T for the rotation shaft a to pass through.

10. A pressure-resistant motor as recited in claim 1, wherein a normal direction of the first engaging face is parallel to a direction of gravity.

11. A pressure-resistant motor as recited in claim 1, wherein a normal direction of the first bonding surface is the same as a direction of gravity.

12. A pressure-resistant motor as recited in claim 1, wherein a normal direction of the first bonding surface intersects with a direction of gravity.

13. A pressure-resistant motor as recited in claim 1, wherein a normal direction of the first bonding surface is orthogonal to a direction of gravity.

14. A pressure resistant motor as recited in claim 1, wherein the motor includes a first outlet box, the sealed housing includes a first opening, the first outlet box is disposed in correspondence with the first opening and forms a sealing engagement with the outer wall surface of the sealed housing, and at least one cable extends to the first outlet box through the first opening.

15. A pressure resistant motor as recited in claim 14, wherein the first outlet box includes at least one sealed joint, and the at least one cable extends outside the first outlet box through the sealed joint.

16. A pressure resistant motor as recited in claim 15, wherein the sealing joint comprises a fixing member, a fastener and a locking member, the fixing member forms a sealing engagement with the first outlet box, the fastener is retained by the fixing member to engage with the cable, the locking member is movably disposed on the fixing member and positions the fastener on the fixing member.

17. A pressure resistant motor as recited in claim 14, including a second outlet box, said sealed housing including a second opening, said second outlet box being disposed in correspondence with said second opening and in sealing engagement with an outer wall surface of said sealed housing, at least one other cable extending through said second opening to said second outlet box.

18. A pressure resistant motor as recited in claim 17, wherein said second outlet box is disposed on said outer wall surface of said sealed casing opposite said first outlet box.

19. A pressure resistant motor as recited in claim 17, wherein said second outlet box is disposed adjacent to said first outlet box on said outer wall surface of said sealed housing.

20. A pressure-resistant motor as recited in claim 14, wherein said at least one cable is connected to a power supply.

21. A pressure resistant motor as recited in claim 1, wherein the shaft is connected to a fan blade set disposed in the pressure vessel.
