Description

Technical Field

[0001] This utility model relates to the field of stirring mechanism technology, and in particular to a magnetically levitated stirring paddle. Background Technology

[0002] In current biopharmaceutical processes, animal, plant, or microbial cells are typically cultured in bioreactors to obtain the desired cell expression products. To reduce the damage caused by the sensitivity of cells and cell expression products to external forces, traditional agitators are often replaced with magnetically levitated agitators driven by magnetic coupling. Magnetic levitated agitators typically include a welded disk or support inside the bioreactor and an impeller disk rotating around the welded disk or support. The impeller disk has an impeller and a rotor magnet. A drive magnet acting on the rotor magnet is located outside the bioreactor. Through the magnetic coupling effect generated by the external drive magnet on the internal rotor magnet, the impeller disk is driven to rotate and levitate relative to the welded disk or support. Currently used stirring mechanisms are relatively complex to install due to design flaws in the connection structure. Therefore, it is necessary to develop a magnetically levitated agitator that is easy to assemble. A search revealed no technical solutions identical to this invention. Utility Model Content

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figures 1 to 3 As shown, the present invention includes: a magnetic levitation stirring paddle, comprising a fixing part 100 and a stirring body 200, wherein the fixing part 100 is provided with a mounting cavity 101; the stirring body 200 can be assembled with the mounting cavity 101, and the stirring body 200 can rotate within the mounting cavity 101 along the axis of the mounting cavity 101.

[0020] Specifically, the stirring body 200 includes a rotating part 210 and an impeller assembly disposed on the rotating part 210. The rotating part 210 is provided with a connecting hole 211, and both ends of the connecting hole 211 have a chamfered design to make the structure smoother. The connecting hole 211 penetrates the front end face and the rear end face of the rotating part 210. A positioning ring 213 is provided on the inner wall of the connecting hole 211. The positioning ring 213 is used to limit and position the connecting pipe 221 when it is inserted into the connecting hole 211 during assembly. The impeller assembly includes an impeller seat 220 and blades 231 disposed on the front side of the impeller seat 220. At least 8 blades 231 with the same structure are evenly distributed on the impeller seat 220. The impeller assembly also includes a reinforcing ring 232 that sequentially reinforces all blades 231. The reinforcing ring 232 prevents the tilt angle of the blades 231 from changing during stirring, and stabilizes and fixes the initial design angle of the blades 231.

[0021] The impeller seat 220 is also provided with a connecting tube 221 on the back side. The connecting tube 221 can be inserted into the connecting hole 211. The inner wall of the connecting tube 221 is provided with a connecting thread. The connecting hole 211 is also provided with a connecting bolt 240 that is inserted from the rear end face of the rotating part 210 and fixed with the connecting thread. In the above structure, the impeller assembly is connected and fixed to the rotating part 210 by the cooperation of the connecting screw and the connecting thread. In this assembly, the positioning ring 213 also cooperates with the connecting screw to complete the positioning function.

[0022] Specifically, a connecting seat 212 is provided on the front end face of the rotating part 210. The connecting seat 212 is arranged along the circumferential direction of the connecting hole 211. An annular groove is provided on the upper end face of the connecting seat 212. An annular block that can be embedded in the annular groove is also provided on the back side of the impeller seat 220 around the connecting tube 221. In the above structure, the ingenious design of the annular groove and the annular block makes the assembly of the impeller assembly and the rotating part 210 more accurate and convenient.

[0023] Specifically, the opening edge of the mounting cavity 101 is provided with an elastic retaining ring 103. In the above structure, when the rotating part 210 is assembled, the rotating part 210 contacts the elastic retaining ring 103 and presses it down, causing the elastic retaining ring 103 to expand and deform outward. The rotating part 210 enters the mounting cavity 101, and the elastic retaining ring 103 resets, thereby limiting the rotating part 210 and preventing it from leaving the mounting cavity 101.

[0024] Specifically, the bottom of the mounting cavity 101 is provided with a positioning protrusion 102. The positioning protrusion 102 is located on the axis of the mounting cavity 101 and can be inserted into the connecting hole 211 on the rotating part 210. The positioning protrusion 102 of the above structure cooperates with the connecting hole 211 so that the rotation direction of the rotating part 210 always revolves around the axis of the mounting cavity 101 and will not deviate.

[0025] Specifically, the blade 231 in the above structure is arc-shaped.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
