Description

Technical Field

[0001] The utility model relates to the technical field of vortex mixer equipment, and in particular to a vortex mixer component suitable for mixing multiple samples, mainly used for long-term mixing operations of samples loaded in multiple ampoules in experiments, such as mixing operations for bacterial endotoxin indicator inspection during tunnel oven verification. Background Art

[0002] A vortex mixer is an instrument that combines oscillation and vortexing. It is widely used in laboratories. It can quickly mix solutions, standards and other liquids in the form of high-speed vortexes, provide support for the uniformity of samples and standards, and greatly improve the reproducibility of experimental results.

[0003] The mixing requirements for standard samples in vaccine bacterial endotoxin testing are very strict, and high-speed oscillation mixing is required for 15 minutes. At present, the vortex mixer used in the laboratory includes a base body, guide rods, fixed plates, bolt locking structure, and fixed plate (upper and lower fulcrum) structure. Based on the above structure, standard samples often tilt and other displacements during the mixing process, and liquids are easy to spill, so personnel are needed to assist in mixing.

[0004] In the validation of a dry heat sterilizer (or tunnel oven), multiple bacterial endotoxin indicators are used at one time. The test for testing their content requires not only that they be mixed for 15 minutes, but also that at least 24 be mixed at one time. Existing vortex mixers are unable to meet this requirement. Utility Model Content

[0005] According to the technical problems raised above, a vortex mixer assembly suitable for mixing multiple samples is provided, which can not only increase the fixation degree of the samples, but also mix a large number of samples at one time, thereby improving work efficiency. The utility model is suitable for mixing multiple ampoules at the same time and for a long time, so as to solve the problems of displacement and low operating efficiency of personnel when multiple ampoules are mixed at the same time and for a long time in the above background technology. The technical means adopted by the utility model are as follows:

[0006] A vortex mixer assembly suitable for mixing multiple samples comprises a fixed plate, a first connecting rod, a second connecting rod and a locking piece. A guide rod and a spring fixing block are provided on the vortex mixer matched with the vortex mixer assembly.

A transverse screw hole is arranged at the end of the first connecting rod. The specification of the longitudinal through hole matches that of the guide rod, and the specification of the transverse screw hole matches that of the locking piece. A longitudinally arranged soft spring is connected to the end of the second connecting rod. The lower end of the soft spring is connected to the spring fixing block. A space for accommodating the tops of multiple groups of ampoules is provided at the bottom of the fixed plate, so as to limit the position of the ampoules during the mixing process.

[0007] Furthermore, the locking member includes a locking bolt.

[0008] Furthermore, the main body of the fixing plate is flush with the first connecting rod and the second connecting rod, and a fixing plate protection edge protruding from the main body is provided at the bottom of the fixing plate.

[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 3 As shown, the embodiment of the utility model discloses a vortex mixer assembly suitable for mixing multiple samples, including a fixed plate 1, a first connecting rod, a second connecting rod and a locking piece. A guide rod 8 and a spring fixing block 7 are arranged on the vortex mixer matched with the vortex mixer assembly. The first connecting rod and the second connecting rod are respectively arranged at the two ends of the fixed plate. A longitudinal through hole 3 is opened on the first connecting rod, and a transverse screw hole, i.e., a bolt through hole 5, is arranged at the end of the first connecting rod. The longitudinal through hole specification matches the guide rod, and the transverse screw hole specification matches the locking piece. The end of the second connecting rod is connected to a longitudinally arranged soft spring 2 through the opened spring fixing hole 4, and the lower end of the soft spring is connected to the spring fixing block. The bottom of the fixed plate is provided with a space for accommodating the tops of multiple groups of ampoules, which is used to limit the position of the ampoules during the mixing process. The soft spring used in the utility model can ensure that there is a downward pulling force during the vibration process, so that the vibrated object will not shift. The spring fixing block is welded on the vortex mixer.

[0021] The locking member comprises a locking bolt 6 .

[0022] The main body of the fixing plate is flush with the first connecting rod and the second connecting rod, and a fixing plate protection edge protruding from the main body is provided at the bottom of the fixing plate. The contact surface of the fixing plate with the ampoule bottle is made of soft silicone material, and the non-contact surface is made of metal material with a larger area. The fixing plate protection edge provided on the side in contact with the ampoule bottle can ensure that when the maximum ampoule usage of the fixing plate is met, multiple ampoules will not shift during the simultaneous and long-term vibration mixing process.

[0023] Hooks are respectively arranged at both ends of the soft spring so that the soft spring can be detachably connected between the second connecting rod and the spring fixing block.

[0024] Taking the WH-3 type vortex mixer in the laboratory as an example, the specific use process of the utility model is as follows: first, multiple ampoules to be mixed are fixed with rubber bands, placed on the mixer base, the through hole of the first connecting rod is aligned with the guide rod, the guide rod passes through the first connecting rod, and is pressed above the ampoule to determine the use height, and then the locking bolt is manually rotated to fix the side of the first connecting rod, the soft spring is assembled to the second connecting rod, and the lower part of the soft spring on the other side is hooked in the spring fixing hole; turn on the vortex mixer, and when the vibration mixing is completed, the soft spring hooked in the spring fixing hole is removed, and the locking bolt on the other side is rotated in the opposite direction to separate the fixed plate assembly from the guide rod and remove the device. The vortex mixer assembly of the present invention has the function of satisfying the simultaneous and long-term vibration mixing of multiple ampoules, preventing the displacement and scattering of mixed samples, reducing personnel operation, and improving experimental efficiency.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
