[0068] Furthermore, the circumferential cutting groove 912 and the circumferential cutting swing groove 914 are distributed in two or three at equal intervals in the circumferential direction; the number of the stirring paddle assembly 92 is the same as that of the circumferential cutting groove 912.

[0069] Furthermore, the distal end of the hinged circular shaft 133 is also provided with a guide cone 136.

[0070] It should be noted that the outer edge of the arc-shaped paddle arm 11 is fitted with a scraper that fits into the body 9 of the concentration tank. The scraper is preferably made of food-grade polytetrafluoroethylene or food-grade polypropylene.

[0071] It should be noted that the two arc-shaped claws 122 are spliced ​​together in the horizontal plane to form a complete circle, which increases the overall structural stability of the multiple lower paddle components 1 when they rotate with the stirring shaft 911.

[0072] The spherical vacuum concentrator described in this case has a detachable impeller assembly 92, which facilitates installation and disassembly.

[0073] The installation method of the impeller assembly 92 of the spherical vacuum concentrator described in this case is as follows:

[0074] S1, Connect and fix the lower propeller assembly 1:

[0075] Insert the lower paddle assembly 1 into the concentrator body 9 through the manhole with the lower plug part 12 facing downwards;

[0076] Keep the arc-shaped claw 122 close to the outer wall of the circumferential groove 912, insert the arc-shaped insert plate 123 into the arc-shaped slot 913, and complete the insertion and fixing of the lower paddle assembly 1 and the stirring shaft 911.

[0077] S2, Insert and fix crossbar assembly 2:

[0078] S2.1, Initial insertion of crossbar assembly 2:

[0079] Insert the crossbar assembly 2 into the body 9 of the concentration tank;

[0080] Align the hinged cylinder 23 from front to back and fit it onto the hinged circular shaft 133;

[0081] S2.2, Axial movement degree of freedom of the automatic locking crossbar assembly 2:

[0082] The hinged cylinder 23 moves backward;

[0083] The guide cone 136 presses the inner locking tooth 66 and the driven insert rod 67 to move radially outward. The driven insert rod 67 acts on the active inclined hole 64, thereby driving the rotating ring 61 to rotate in the opposite direction against the damping of the reset torsion spring 63.

[0084] As per the instruction manual Figure 11 , 16 As shown, when the hinged cylinder 23 moves backward until the inner locking teeth 66 align with the anti-detachment ring groove 134, the reset torsion spring 63 drives the rotating ring 61 and the active inclined hole 64 to rotate, thereby driving the driven insert rod 67 and the inner locking teeth 66 to be inserted radially inward into the anti-detachment ring groove 134, locking the axial movement freedom of the crossbar assembly 2.

[0085] S2.3, the crossbar assembly 2 automatically opens and fixes upward:

[0086] As per the instruction manual Figure 14 As shown;

[0087] During the rearward movement of the hinged cylinder 23, the outer ring locking hole 724 is always locked by the inner locking tooth 52, and the actuating torsion spring 712 is in a stored state.

[0088] As per the instruction manual Figure 15 , 16 As shown:

[0089] The inner ring locking rod 725 is inserted into the fixed locking tooth 135 to achieve a locking engagement, and the inner ring locking rod 725 is blocked by the longitudinal rod body 132 and cannot move further backward;

[0090] The hinged cylinder 23, the torsion cavity assembly 5, the axial limiter 6, and the torsion component 71 continue to move backward relative to the upper hinge portion 13, while the clutch component 72 remains stationary relative to the upper hinge portion 13 (only the clutch spring 723 is passively compressed) until the outer ring locking hole 724 disengages from the locking contact with the locking tooth 52 in the cavity, at which point the torque of the actuating torsion spring 712 is released;

[0091] Since the rear end of the actuating torsion spring 712 is connected to the upper hinge part 13 through the clutch assembly 72, and the front end is connected to the crossbar assembly 2 through the annular worm gear 714 and the driving worm 715 (as per the attached manual) Figure 14 , 15 As shown in Figure 16), the torsion spring 712 relaxes, thereby causing the crossbar assembly 2 to open upwards (as shown in the attached manual). Figure 5 , 6 (as shown)

[0092] The fixing of the crossbar assembly 2 and the stirring shaft 911 is completed when the fastening protrusion 22 is inserted into the fastening groove 915.

[0093] S3, repeat the above steps to complete the fixing of all impeller assemblies 92.

[0094] As a further implementation, the torque of the actuating torsion spring 712 can also be adjusted:

[0095] Rotating the active worm gear 715 drives the annular worm wheel 714 to rotate, thereby adjusting the degree of torsion and torque of the actuating torsion spring 712 under normal conditions.

[0096] It should be noted that the impeller assembly 92 is easy to disassemble:

[0097] First, the lower crossbar assembly 2:

[0098] The crossbar assembly 2 is pressed down through the manhole to overcome the damping of the action torsion spring 712 and swings down around the axis, and the fastening protrusion 22 slides out of the fastening groove 915;

[0099] Then, raise and lower propeller assembly 1:

[0100] At the same time, the lower propeller assembly 1 is lifted upwards, and the arc-shaped insert plate 123 is pulled out from the arc-shaped slot 913;

[0101] Finally, the agitator assembly 92 is extracted through the manhole.

The torsion assembly (71) further includes an annular worm gear (714) rotatably disposed in the adjustment cavity (55) and an active worm gear (715) rotatably disposed in the worm longitudinal hole (56) and meshing with the annular worm gear (714). The actuating torsion spring (712) is connected at one end to a torsion ring (711) and at the other end to a ring worm gear (714).

3. The spherical vacuum concentration vessel for extracting animal bone marrow according to claim 2, characterized in that: The circumferential cutting groove (912) and the circumferential cutting swing groove (914) are distributed at equal intervals in the circumferential direction, with two or three of them. The number of the stirring paddle assembly (92) is the same as the number of the annular grooves (912).

4. A spherical vacuum concentration vessel for extracting animal bone marrow according to claim 3, characterized in that: The distal end of the hinged circular shaft (133) is also provided with a guide cone (136).
