[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-6 , the utility model provides a technical solution:

[0028] A biological reagent preparation device, comprising

[0029] A mounting base 2 and a mixing container 1 disposed above the mounting base 2, wherein a stirring mechanism for mixing and stirring the biological reagent is disposed inside the mixing container 1, and a driving mechanism for driving the stirring mechanism to rotate is disposed at the bottom of the mounting base 2;

[0030] In this embodiment, in order to facilitate observation of the liquid inside the mixing container 1, a transparent observation plate 20 is provided on the mixing container 1, through which the liquid level inside the mixing container 1 can be easily observed;

[0031] A discharge rack 14 is connected to the top of the mixing container 1. The top of the discharge rack 14 is connected to a connecting pipe 16. A feed hopper 15 is provided at the upper end of the connecting pipe 16. A connecting seat 18 is fixedly connected to the bottom of the feed hopper 15. A threaded seat 19 is fixedly connected to the surface of the connecting pipe 16. The threaded seat 19 is threadedly installed in the connecting seat 18. The connecting pipe 16 is connected to the feed hopper 15.

[0032] In this embodiment, the raw material liquid for manufacturing the biological reagent can be conveniently added to the preparation container 1 through the feed hopper 15. After the liquid is stirred and mixed, when it is necessary to discharge and collect the fully stirred and mixed liquid, the feed hopper 15 is rotated to unscrew the connecting seat 18 from the top of the threaded seat 19. The electromagnet 13 is de-energized, so that the force of the electromagnet 13 on the support block 11 is eliminated, so that the preparation container 1 can be removed from the top of the mounting base 2. The valve 17 is opened to discharge the fully stirred and mixed liquid from the connecting pipe 16.

[0033] The stirring mechanism includes a rotating rod 4, a first stirring blade 5 and a second stirring blade 6. The rotating rod 4 is rotatably mounted inside the mixing container 1. The first stirring blade 5 and the second stirring blade 6 are respectively arranged at the lower part and the upper part of the rotating rod 4.

[0034] The blade angles of the first stirring blade 5 and the second stirring blade 6 are set in opposite directions;

[0035] It is worth mentioning that, by means of the first stirring blade 5 and the second stirring blade 6 arranged in opposite directions, when the first stirring blade 5 rotates, the liquid at the bottom of the mixing container 1 is pushed upward, while the second stirring blade 6 with the top downward pushes the liquid at the top downward, which can promote the formation of convection and turbulence of the liquid in the barrel, thereby accelerating the efficiency of rapid mixing of the liquid and the effect of homogenization;

[0036] The inner wall of the mixing container 1 is fixedly connected with a bracket 7, and the rotating rod 4 is rotatably installed in the bracket 7;

[0037] It is worth noting that the bracket 7 can improve the stability of the rotating rod 4 during rotation;

[0038] The driving mechanism includes a driving motor 3, a square column 9 and a fixing base 8. The driving motor 3 is fixedly mounted on the bottom of the mounting base 2. The square column 9 is fixedly mounted on the output shaft of the driving motor 3. The fixing base 8 is fixedly mounted on the lower end of the rotating rod 4. The square column 9 is tapered. The bottom of the fixing base 8 is provided with a square groove 10 adapted to the square column 9. The square column 9 is inserted into the square groove 10.

[0039] It is worth noting that the square column 9 is inserted into the square groove 10 of the fixing base 8, so that the square column 9 can be easily separated from the fixing base 8;

[0040] A valve 17 is provided on the connecting pipe 16, a sealing ring 21 is provided on the inner wall of the fixing seat 8, and the top of the threaded seat 19 is pressed against the sealing ring 21;

[0041] Furthermore, by opening the valve 17, the fully stirred and mixed liquid can be discharged from the connecting pipe 16, and the sealing ring 21 can improve the sealing between the threaded seat 19 and the fixed seat 8, thereby preventing the liquid from leaking through the gap between the threaded seat 19 and the fixed seat 8;

[0042] A through hole 22 is formed at the bottom of the feed hopper 15, and the connecting pipe 16 is inserted into the through hole 22;

[0043] The bottom of the mixing container 1 is fixedly connected to a plurality of support blocks 11 arranged in a circular array. The top of the mounting base 2 is provided with positioning grooves 12 adapted to the support blocks 11. The support blocks 11 are inserted into the positioning grooves 12.

[0044] An electromagnet 13 is provided in the positioning groove 12, and the support block 11 is adsorbed and fixed on the electromagnet 13;

[0045] In this embodiment, the support block 11 is made of ferromagnetic material, and the electromagnet 13 adsorbs the support block 11, thereby adsorbing and fixing the mixing container 1 on the mounting base 2;

[0046] Preferably, the ferromagnetic material can be set to one of the three ferromagnetic materials of iron, cobalt and nickel. Iron, cobalt and nickel are in large supply and relatively low in price, which is conducive to procurement and use by enterprises;

[0047] During specific use, the raw material liquid for manufacturing the biological reagent is first added to the mixing container 1 through the feed hopper 15, and the output shaft of the driving motor 3 rotates to drive the square column 9 to rotate, so that the square column 9 cooperates with the fixing seat 8 and the rotating rod 4 to drive the first stirring blade 5 and the second stirring blade 6 to rotate. When the first stirring blade 5 rotates, the liquid at the bottom of the mixing container 1 can be pushed upward, while the second stirring blade 6 with the top downward pushes the upper liquid downward. The first stirring blade 5 and the second stirring blade 6 arranged in opposite directions can promote convection and turbulence of the liquid in the barrel, thereby accelerating the efficiency of rapid mixing of the liquid and the effect of homogenization;

[0048] After the liquid is stirred and mixed, when it is necessary to discharge and collect the fully stirred and mixed liquid, the feed hopper 15 is rotated to unscrew the connecting seat 18 from the top of the threaded seat 19, and the electromagnet 13 is powered off, so that the force of the electromagnet 13 on the support block 11 disappears, so that the preparation container 1 can be removed from the top of the mounting seat 2, and the valve 17 is opened to discharge the fully stirred and mixed liquid from the connecting pipe 16.

[0049] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
