Description

Technical Field

[0001] This utility model relates to the field of freeze-dried reagent production equipment, and in particular to a separation machine for glan and drop beads. Background Technology

[0002] As core materials for disease detection and bioanalysis, diagnostic reagents directly impact the accuracy of test results and the commercial application of the products due to the stability of their dosage forms and the reliability of their preparation processes. Currently, lyophilized diagnostic reagents are gradually replacing traditional liquid reagents as the mainstream choice due to their advantages such as room temperature storage, long shelf life, and ease of transportation. However, their industrial production still faces significant technical challenges: conventional lyophilization processes require filling trace amounts of liquid reagents (10-50 μL) into lyophilization containers, but traditional filling equipment is easily affected by fluctuations in ambient temperature and humidity during the distribution of trace amounts of liquid, leading to rapid evaporation of the liquid, denaturation of active ingredients, or concentration shifts, which seriously affect reagent performance. In addition, during the pre-freezing stage, uneven cooling rates within the trace droplets can easily form large ice crystals, causing irreversible damage to protein structures or unexpected chemical reactions between reagent components, resulting in batch-to-batch quality fluctuations and restricting the consistency of large-scale product production.

[0003] To address these issues, the industry has widely adopted dropper technology. This technology combines precise, micro-level dispensing with ultra-low temperature rapid freezing to suppress liquid evaporation and shorten pre-freezing time, thereby reducing ice crystal growth and chemical side reactions. However, the separation grid (also known as the liquid separator grid) in existing droppers has design flaws that limit its practical application: traditional separation grids are manufactured using integral metal stamping or precision etching processes, resulting in complex structures, large sizes, and inconvenient manufacturing and use.

[0025] Figure 1 This is a schematic structural diagram of a separable gland provided in one embodiment of this utility model. Figure 1 As shown in the figure, a separation grating provided by this utility model embodiment includes a central tube 1, a plurality of first fins 2 and a plurality of second fins 3. The side of the first fins 2 is connected to the outer wall of the central tube 1. The first fins 2 are evenly arranged along the circumferential direction of the central tube 1 and extend along the radial direction of the central tube 1. At least one second fin 3 is provided between two adjacent first fins 2, and the two ends of the second fin 3 are respectively connected to two first fins 2.

[0026] In this embodiment of the invention, the separation gland is manufactured by welding the first fin 2 to the central tube 1, and then welding the second fin 3 sequentially from the inside to the outside. The manufacturing process is simple. Furthermore, the number and spacing of the second fins 3 between the two first fins 2 can be changed according to the usage requirements, thereby changing the volume of the separation gland for ease of use.

[0027] In one embodiment of the present invention, a second fin 3 is provided between every two adjacent first fins 2, and the second fin 3 is provided at the end of the first fin 2 away from the central tube 1.

[0028] In an alternative embodiment of this invention, a plurality of second fins 3 are disposed between each pair of adjacent first fins 2. The plurality of second fins 3 located between two adjacent first fins 2 are parallel to each other, so that the plurality of second fins 3 are located on different circular trajectories, thereby dividing the space between adjacent first fins 2 into a plurality of grids 8 by the second fins 3.

[0029] Specifically, the number of first fins 2 is 10 to 60. The number of second fins 3 arranged between every two adjacent first fins 2 is 2 to 8. The number of first fins 2 and second fins 3 can be set according to usage requirements. The first fins 2 are welded to the central tube 1 and the second fins 3.

[0030] like Figures 2 to 5 As shown, the separating gland provided by this utility model is manufactured using the following fixture assembly and method. The fixture assembly includes a base plate 4, on which a circular hole 41 coaxial with the central tube 1 is provided. The base plate 4 also has a first groove 42 and a second groove 43. The first groove 42 is evenly distributed along the circumferential direction of the circular hole 41 and is arranged in a one-to-one correspondence with the first fin 2. The second groove 43 is arranged around the circular hole 41. A welding hole 44 is provided at the connection position of the first groove 42 and the second groove 43 on the base plate 4. During manufacturing, the central tube 1 is first placed vertically on the base plate 4. The first fin 2 is inserted into the first groove 42 and the second fin 3 is inserted into the second groove 43. The connection position of the first fin 2 and the second fin 3 is exposed in the welding hole 44, and the first fin 2 and the second fin 3 can be welded through the welding hole 44.

[0031] Furthermore, the clamping assembly also includes a first clamp 5, which comprises a connecting piece and a limiting member. The connecting piece is an annular structure with an inner diameter larger than the diameter of the central tube 1. The limiting member is annular and disposed on one side of the connecting piece, and has limiting grooves 51 corresponding one-to-one with the first fins 2. During manufacturing, the top end of the first fin 2 is inserted into the limiting groove 51 to limit its position.

[0032] Furthermore, the clamping assembly also includes a second clamp 6, which is annular in structure and has a slot 61 for engaging the first fin 2. Multiple second clamps 6 are present, with increasing diameters, and are nested sequentially, with gaps between adjacent clamps 6. During fabrication, the second clamp 6 is positioned on top of the first fin 2, with the top end of the first fin 2 engaging in the slot 61. The second fin 3 is inserted between two first fins 2 through the gap between two clamps 6, thus limiting its position. Additionally, the clamping assembly includes a third clamp 7, which is also annular in structure. During manufacturing, the third clamp 7 is engaged at the end of the first fin 2 furthest from the central tube 1, with its inner edge abutting against the second fin 3. By configuring the clamping assembly, the positions of the first fin 2 and the second fin 3 can be relatively fixed before welding, preventing misalignment during welding and improving welding quality.

[0033] like Figure 6 As shown, this embodiment of the invention also provides a dripping machine, including a driving device, a needle assembly 9, and a separating gland as described in any of the above embodiments; the driving device is used to output rotational motion, and the separating gland is detachably mounted on the driving device; the needle assembly is disposed above the separating gland and is used to drip liquid into the separating gland; the needle assembly has a plurality of needles 91 spaced apart along the radial direction of the separating gland, each needle 91 being located directly above a cell 8. In application, the cell 8 is filled with liquid nitrogen, and the liquid medicine dripped from the needle 91 falls into the cell 8, is frozen into a solid by the liquid nitrogen, and settles to the bottom of the cell 8. After each drop of liquid medicine falls into the cell 8, the separating gland rotates once, so that the cell 8 that has not yet received liquid medicine is facing the needle 91, and the liquid medicine settles before the separating gland completes one full rotation, so that each cell can only contain a maximum of one drop of liquid medicine to prevent two drops of liquid medicine from sticking together.

[0034] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
