[0039] like Figure 1-12 As shown, an auxiliary device for disassembling and assembling a reactor in this embodiment comprises a support tube 1, wherein the support tube 1 is arranged vertically, a connecting tube 2 is arranged at the top of the support tube 1, and the connecting tube 2 is arranged horizontally. A connecting ring 3 is sleeved on the support tube 1, and the connecting ring 3 is rotatably connected to the support tube 1 through a first bearing 4. A support member 5 and two clamping blocks 6 are arranged on the connecting tube 2, wherein the support member 5 is arranged at the top of the connecting tube 2, and the two clamping blocks 6 are arranged circumferentially symmetrically with respect to the support tube 1, and the clamping surface of the clamping block 6 is arc-shaped. A rotating assembly 7 is arranged on the connecting tube 2, and the rotating assembly 7 is used to drive the two clamping blocks 6 to rotate in opposite directions around the axis of the connecting tube 2;

[0040] The device has the following two states:

[0041] Idle state, at this time, the two clamping blocks 6 are located below the connecting pipe 2;

[0042] Working state, at this time, the two clamping blocks 6 are located above the connecting pipe 2;

[0043] During operation, when it is necessary to disassemble the stirring shaft 100, first insert the support tube 1 into the discharge port at the bottom of the reactor, and fix the connecting ring 3 to the flange end on the discharge port. At the same time, by calculation, the support member 5 is against the bottom of the stirring shaft 100 in the reactor, and the stirring shaft 100 is supported by the support member 5. Subsequently, the two clamping blocks 6 are driven to rotate around the axis of the connecting tube 2 by the rotating assembly 7, and the rotation directions of the two clamping blocks 6 are opposite, and the two clamping blocks 6 are respectively against the front and rear sides of the stirring shaft 100, that is, the clamping surface of the clamping block 6 is against the stirring shaft 100. The shaft 100 is fitted to achieve the clamping of the stirring shaft 100. After that, the support tube 1 is rotated to rotate the rotating tube. The rotation of the support tube 1 causes the clamping block 6 to rotate synchronously through the rotating assembly 7, that is, the clamping block 6 drives the stirring shaft 100 to rotate, so that the stirring shaft 100 is removed from the reducer. The support of the stirring shaft 100 by the support member 5 and the clamping of the stirring shaft 100 by the two clamping blocks 6 can avoid the displacement or tilt of the stirring shaft 100 in the up-down, front-back and left-right directions after disassembly, thereby preventing the stirring shaft 100 from colliding with the reactor body and being damaged.

[0044] When the stirring shaft 100 needs to be installed on the reducer, the support tube 1 is rotated in the reverse direction, so that the clamping block 6 drives the stirring shaft 100 to rotate in the reverse direction, so that the stirring shaft 100 is installed on the reducer;

[0045] The rotating assembly 7 includes a driving shaft 71 and two rotating units 72. The driving shaft 71 coaxially passes through the support tube 1. The driving shaft 71 is rotatably connected to the support tube 1 through a second bearing 73. A driving bevel gear 74 is installed on the driving shaft 71. The two rotating units 72 are evenly distributed circumferentially around the driving shaft 71. The two rotating units 72 are respectively connected to two clamping blocks 6. The driving bevel gear 74 is connected to both rotating units 72. A locking member 75 is provided at the bottom end of the driving shaft 71. The locking member 75 is used to achieve locking between the driving shaft 71 and the support tube 1.

[0046] The rotating unit 72 includes a transmission shaft 721, a mounting rod 722 and a connecting rod 723. The transmission shaft 721 is coaxially inserted into the connecting pipe 2. The transmission shaft 721 is connected to the connecting pipe 2 through a connecting bearing 724. A driven bevel gear 725 is installed on the transmission shaft 721. The driving bevel gear 74 is meshed with the driven bevel gear 725. The mounting rod 722 is parallel to the transmission shaft 721. The mounting rod 722 is located outside the connecting pipe 2. One end of the connecting rod 723 is fixedly arranged on the transmission shaft 721. One end of the mounting rod 722 is fixedly arranged on the connecting rod 723. The clamping block 6 is connected to the mounting rod 722.

[0047] The driving shaft 71 is rotated to rotate the driving shaft 71, and the rotation of the driving shaft 71 drives the driving bevel gear 74 to rotate. The rotation of the driving bevel gear 74 drives the transmission shaft 721 to rotate through the driven bevel gear 725. The rotation of the transmission shaft 721 drives the mounting rod 722 to rotate through the connecting rod 723. The rotation of the mounting rod 722 drives the clamping block 6 to rotate synchronously, wherein the rotation directions of the two driven bevel gears 725 are opposite, so that the rotation directions of the two clamping blocks 6 are opposite. When the clamping block 6 clamps the driving shaft 71 and the support tube 1 needs to be rotated, the locking member 75 is used to realize the locking between the driving shaft 71 and the support tube 1, that is, the locking between the locking block and the stirring is realized. When the support tube 1 rotates, the clamping block 6 can drive the stirring shaft 100 to rotate.

[0048] The end of the mounting rod 722 away from the connecting rod 723 is coaxially rotatably provided with a mounting sleeve 726, and the mounting sleeve 726 is connected to the mounting rod 722 by a torsion spring 727. The clamping block 6 is detachably fixedly connected to the mounting sleeve 726 by a first screw 728. When the mounting rod 722 rotates, the mounting sleeve 726 drives the clamping block 6 to rotate synchronously. During this period, the mounting sleeve 726 and the mounting rod 722 can generate relative rotation and cause the torsion spring 727 to deform. Through the rotation of the mounting sleeve 726, it can be ensured that the clamping surface of the clamping block 6 is in contact with the drive shaft 71. When the clamping block 6 is separated from the drive shaft 71, the elastic action of the torsion spring 727 causes the mounting sleeve 726 and the mounting rod 722 to rotate in the opposite direction, thereby realizing the reset between the mounting sleeve 726 and the mounting rod 722;

[0049] The locking member 75 includes a rotating sleeve 751, which is coaxially sleeved on the bottom end of the support tube 1. The rotating sleeve 751 is fixedly arranged on the bottom end of the drive shaft 71. The rotating sleeve 751 is locked with the support tube 1 by a second screw 752. When the clamping block 6 needs to rotate around the axis of the connecting tube 2, the second screw 752 is loosened and the rotating sleeve 751 is rotated so that the rotating sleeve 751 drives the drive shaft 71 to rotate. When the support tube 1 needs to rotate, the second screw 752 is tightened so that the support tube 1 and the drive shaft 71 can maintain a relatively static position relationship, that is, the locking between the drive shaft 71 and the support tube 1 is achieved;

[0050] A rotating block 753 is fixedly disposed at the bottom of the rotating sleeve 751. The function of the rotating block 753 is to facilitate the use of tools such as a wrench to drive the rotating sleeve 751 to rotate.

[0051] A clamping plate 8 is fixedly arranged on the clamping block 6, wherein the stirring shaft 100 includes a shaft body portion 101 and a stirring portion 102, the shaft body portion 101 is vertically arranged, the stirring portion 102 is arranged at the bottom end of the shaft body portion 101, and the stirring portion 102 is centrally symmetrically arranged about the shaft body portion 101. When the two clamping blocks 6 clamp the stirring shaft 100, the clamping surface of the clamping block 6 fits with the shaft body portion 101, and at the same time, the two clamping plates 8 are respectively clamped on both sides of the stirring portion 102, and at this time, the two clamping plates 8 are arranged opposite to each other and symmetrical about the stirring portion 102. By connecting the clamping plates 8 and the stirring portion 102, relative rotation between the stirring shaft 100 and the clamping blocks 6 can be avoided when the stirring shaft 100 is disassembled;

[0052] A plurality of fixing members 9 are arranged on the connecting ring 3, and the plurality of fixing members 9 are evenly distributed circumferentially with the supporting tube 1 as the center;

[0053] The fixing member 9 includes a fixing block 91, and a third screw 92 is threadedly connected to the fixing block 91. The fixing block 91 is locked with the support tube 1 by the third screw 92. When the clamping block 6 needs to rotate around the axis of the connecting tube 2, the fixing block 91 is locked with the support tube 1 by the third screw 92. When the support tube 1 needs to rotate, the third screw 92 is loosened so that the support tube 1 can rotate normally.

[0054] The support member 5 includes a support block 51 and a ball 52. The support block 51 is fixedly arranged on the top of the connecting tube 2. The ball 52 rolls and embeds in the top of the support block 51. During operation, the ball 52 abuts against the bottom of the stirring shaft 100, thereby supporting the stirring shaft 100. At the same time, when the stirring shaft 100 is clamped, when the connecting rod 723 first abuts against the stirring shaft 100 and pushes the stirring shaft 100 to rotate, the friction between the support member 5 and the stirring shaft 100 can be reduced by the ball 52.

[0055] To sum up, by rotating the two clamping blocks 6 to clamp the stirring shaft 100 and by supporting the stirring shaft 100 with the support member 5, it is possible to avoid the stirring shaft 100 from being offset or tilted in the up and down, front and back, left and right directions after being disassembled, thereby preventing the stirring shaft 100 from colliding with the reactor body and being damaged. In addition, it should be pointed out that when the positioning U-card is sleeved on the stirring shaft 100 in the prior art, the positioning U-card and the stirring shaft 100 need to be kept within a certain angle range so that the positioning U-card can be smoothly sleeved on the stirring shaft 100. In the present application, it is only necessary to prevent the clamping block from being in direct contact with the stirring part 102 during the rotation around the axis of the connecting pipe 2, and the angle at which smooth disassembly and assembly can be achieved is significantly increased, thereby improving the convenience of disassembly and assembly.

[0056] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
