Abstract
Description
Technical Field
[0001] This utility model relates to a quantitative testing device for fiber dissolution, and more specifically to a testing container for a quantitative testing machine for fiber dissolution. Background Technology
[0002] The prior art includes a utility model patent with publication number CN218496927U entitled "A Device for Fiber Composition Analysis", which discloses a method of dissolving fibers by setting up a dissolving vessel. However, this patent only sets up one dissolving container, so it can only process one sample at a time, which cannot meet the needs of large-scale testing. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a test container for a fiber dissolution quantitative tester that can effectively meet the needs of large-scale testing.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a test container for a fiber dissolution quantitative tester, comprising a fixed bed fixedly installed in the middle of an external frame and several containers arranged on the fixed bed, wherein the fixed bed is provided with a reagent flow channel, and the reagent flow channel is connected to several containers to inject reagents into the containers.
[0005] As a further improvement of this utility model, the container includes an outer cup and an inner cup. The outer cup is fixedly installed on a fixed bed, and the inner cup is inserted into the outer cup, with its lower end communicating with the reagent flow channel.
[0006] As a further improvement of this utility model, the side wall of the upper end of the inner cup is bent outward to form a rim. When the inner cup is inserted into the outer cup, the outer wall of the rim abuts against the upper end of the outer cup to restrict the inner cup from sliding down.
[0007] As a further improvement of this utility model, a glass frosted core plate is fixed inside the inner cup near the lower end, which divides the internal space of the inner cup into upper and lower parts.
[0008] As a further improvement of this utility model, an installation groove is provided on the fixed bed at the position relative to the end of the reagent flow channel, and the lower end of the outer cup is inserted into the installation groove and sealed and fixed with the groove wall.
[0009] As a further improvement of this utility model, a sealing ring for installation is provided on the lower outer wall of the outer cup. Sealing rings are installed on the upper and lower end faces of the sealing ring. A ring groove for sealing is opened on the groove wall of the installation groove near the bottom of the groove. When the outer cup is installed into the installation groove, the sealing ring is embedded in the ring groove.
[0010] The beneficial effects of this invention are as follows: By arranging several containers on a fixed bed, parallel processing of multiple samples is achieved, significantly improving detection efficiency, especially suitable for high-throughput detection scenarios. The containers adopt a plug-in structure of outer and inner cups, eliminating the need for manual transfer of liquid inside the beakers and reducing the risk of safety accidents. The rim limiting design ensures stable communication between the inner cup and the reagent flow channel while facilitating quick disassembly and replacement, meeting the differentiated detection needs of different samples. Attached Figure Description
[0011] Figure 1 This is a schematic diagram showing the arrangement of the test containers in the fiber dissolution quantitative tester of this utility model;
[0012] Figure 2 This is a schematic diagram of the test container of the fiber dissolution quantitative tester of this utility model. Detailed Implementation
[0013] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.
[0014] Reference Figure 1 As shown, the test container of the fiber dissolution quantitative tester in this embodiment includes a fixed bed 61 fixedly installed in the middle of the external frame and several containers 62 arranged on the fixed bed 61. The fixed bed 61 is provided with a reagent channel, which is connected to an external reagent tank and water tank via pipes, enabling the reagent or water to be evenly distributed into each container 62. By setting multiple containers 62 on the fixed bed 61, dissolution tests can be performed on multiple fiber samples simultaneously, significantly improving detection efficiency. Compared to devices in the prior art that can only process one sample at a time, this structure achieves parallel processing of multiple samples, effectively solving the problem of low efficiency in large-scale detection, such as... Figure 1 As shown in the figure, this embodiment provides a flow channel structure design for simultaneous liquid inlet of 8 containers 62, 2 containers 62, 2 containers 62, and 4 containers 62. For the flow channel for simultaneous liquid inlet of 8 containers 62, a combination of a main channel and four branch channels is adopted, with each container 62 correspondingly set at the end of the branch channel. For the flow channels for simultaneous liquid inlet of 2 containers 62, 2 containers 62, and 4 containers 62, two independent flow channels, a combination of a main channel and four branch channels are adopted, with each container 62 correspondingly set at the end of the branch channel and the end of the independent flow channel.
[0015] Furthermore, refer to Figure 2As shown, container 62 includes an outer cup 621 and an inner cup 622. The outer cup 621 is fixedly mounted on the fixed bed 61, and the inner cup 622 is inserted into the outer cup 621, with its lower end communicating with the reagent channel within the fixed bed 61. Reagent or water in the reagent channel enters the inner cup 622 through its lower end, where the fiber sample undergoes a dissolution reaction. The outer cup 621 provides support and protection for the inner cup 622. This inner and outer cup insertion structure facilitates the disassembly of a single container 62. When weighing is required after testing, only the inner cup 622 needs to be removed from the outer cup 621, effectively avoiding experimental errors caused by sample transfer residues.
[0016] Furthermore, the upper sidewall of the inner cup 622 bends outward to form a rim 6221. When the inner cup 622 is inserted into the outer cup 621, the outer wall of the rim 6221 abuts against the upper end of the outer cup 621 to restrict the inner cup 622 from sliding down. By forming the rim 6221 on the upper part of the inner cup 622, the rim 6221 can be used to limit the placement of the inner cup 622, thus eliminating the need for a support structure at the lower end of the inner cup 622 and increasing the flow rate into the inner cup 622.
[0017] Furthermore, a glass frit plate 6222 is fixed near the lower end inside the inner cup 622, dividing the internal space of the inner cup 622 into upper and lower parts. The glass frit plate 6222 filters fibers, allowing the dissolved liquid to flow through the plate into the lower space. This structure achieves effective separation of fibers and solution, facilitating subsequent filtration and cleaning operations, avoiding fiber clogging of the flow channel, and improving the smoothness of the detection process.
[0018] Furthermore, a mounting groove is provided on the fixed bed 61 at a position relative to the end of the reagent flow channel. The lower end of the outer cup 621 is inserted into the mounting groove and sealed and fixed to the groove wall by a sealing ring. The sealed connection between the outer cup 621 and the fixed bed 61 prevents reagent leakage from the connection point. In this embodiment, the sealing method is to provide a sealing ring 6211 for installation on the lower outer wall of the outer cup 621, and then install sealing rings 6212 on the upper and lower end faces of the sealing ring 6211. At the same time, an annular groove 6213 for sealing is provided on the groove wall near the bottom of the groove. When the outer cup 621 is inserted, the sealing ring 6211 is embedded in the annular groove 6213, and the sealing is achieved by the sealing ring 6212 abutting against it.
[0019] In summary, this solution constructs a test container system suitable for high-throughput detection through the combined design of the fixed bed 61 and multiple containers 62, the inner and outer cup insertion structure, the glass frit core plate 6221 filtration structure, and the sealing ring design. Compared with the devices in the prior art that can only process one sample at a time, this design enables the parallel dissolution, filtration, and cleaning of multiple fiber samples, significantly improving detection efficiency.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
