[0030] In the description of this utility model, "plurality" means at least two, such as two or three, unless otherwise specifically defined. Furthermore, unless otherwise specified or defined, the terms "mounted," "connected," and "connected" should be understood broadly, meaning, for example, fixed, removable, or integral; mechanical or electrical; direct or indirect through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model in their respective contexts.

[0031] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature.

[0032] The utility model provides a technical solution: a filtering device for constant pressure sugar solution color value determination, which includes a sampling assembly 1 and a receiving container 2, the sampling assembly 1 includes a first cover plate 3, a filter plate 4 and a second cover plate 5 which are arranged in sequence from top to bottom, the first cover plate 3 is provided with a first through hole 6, the filter plate 4 has a plurality of grids 7, the second cover plate 5 is provided with a second through hole 8, the first through hole 6, the grid 7 and the second through hole 8 are connected to each other, the top of the receiving container 2 is provided with a receiving port 9, and the side of the receiving container 2 is provided with a connecting port 10; wherein, the second cover plate 5 is covered on the receiving container 2, and the receiving port 7 is connected to the second through hole 8.

[0033] Specifically, see Figures 1 to 5 The sampling assembly of this filtration device is removable, with the filter plate 4 sandwiched between the first cover plate 3 and the second cover plate 5. To measure the color value of the sugar solution, the suction pump is first connected to the connection port 10 of the receiving container 2, the sampling assembly 1 is then placed on the receiving container 2, and the sugar solution to be filtered is evenly poured into the sampling assembly 1 to complete the filtration. The entire filtration device has a simple structure. Furthermore, after filtration, the filter plate 4 can be removed from the first cover plate 3 and the second cover plate 5 for convenient cleaning.

[0034] In some embodiments, further, in order to facilitate subsequent cleaning, a beaker 19 can be placed in the receiving container 2 to receive the filtrate. This is convenient and has no risk of contamination. During the entire experimental process, the receiving container does not need to be cleaned again. It only needs to be simply rinsed with water after all samples have been filtered.

[0035] As an optional embodiment, in some embodiments, the first cover plate 3 is provided with a first threaded hole 11, and the second cover plate 4 is provided with a second threaded hole 12. The position of the first threaded hole 11 corresponds to the position of the second threaded hole 12. The first cover plate 3 and the second cover plate 2 are fixedly connected by bolts 13. Figure 3 and Figure 5 The first cover plate 3 and the second cover plate 5 are both provided with threaded holes and fixed with bolts 13. This connection method can not only achieve quick disassembly and installation, but also has good anti-vibration performance and can withstand a certain degree of vibration and impact loads.

[0036] As an optional embodiment, in some embodiments, a drainage tube 14 is further included, one end of the drainage tube 14 is provided at the second through hole 8, and the other end of the drainage tube 14 extends into the interior of the receiving container 2 through the receiving port 9. Figure 1 , installing the drainage pipe 14 can ensure that the filtered liquid flows into the receiving container 2 and avoids accidental flow to other places. Further, the drainage pipe 14 can adopt a truncated cone shape, which has a better drainage effect.

[0037] As an optional embodiment, in some embodiments, a buckle seat 17 is provided on the side of the receiving container 2, and a buckle 18 is rotatably connected to the buckle seat 17. Figure 1 In order to further improve the stability, the filter device adopts a snap 18 to flip upward to fix the first cover plate 3.

[0038] As an optional embodiment, in some embodiments, a first sealing ring 15 is further included, and the first sealing ring 15 is arranged at the first through hole 6. Figure 3 The filter device can improve the sealing between the first cover plate 3 and the filter plate 4 by installing the first sealing ring 15, thereby preventing the filter liquid from accidentally leaking out.

[0039] As an optional embodiment, in some embodiments, a second sealing ring 16 is further included, and the second sealing ring 16 is arranged at the receiving interface 9. Figure 2 The filter device can improve the sealing between the second cover plate 5 and the receiving container 2 by installing the second sealing ring 16, thereby preventing the filter liquid from accidentally leaking out.

[0040] As an optional implementation, in some embodiments, the first cover plate 3, the filter plate 4 and the second cover plate 5 are all made of soft materials, and the receiving container 2 is made of hard material.

[0041] Specifically, because existing sugar solution filtration devices on the market are primarily constructed of either purely soft or purely hard materials, these single-material filtration devices present drawbacks. For example, filtration devices constructed entirely of soft materials are susceptible to deformation due to long-term pressure during use, and soft materials are prone to aging, leading to decreased sealing, unstable pressure, and the inability to compact the filter plates, causing displacement, which in turn affects the accuracy of experimental results. Filters constructed entirely of hard materials are heavy and difficult to disassemble and clean, which can easily lead to residual sugar solution and cross-contamination between different sugar solution samples, thus affecting the accuracy and efficiency of the experiment. Therefore, the liquid inlet assembly 1 of this filtration device is constructed of soft materials, such as plastic or silicone, while the receiving container 2 is constructed of hard materials, such as stainless steel or iron. Thus, during the sugar solution color measurement process, after turning on the filtration pump, simply press the first cover plate 3, and the pressure in the sample inlet assembly 1 immediately rises to a constant pressure. Therefore, the filtering device can achieve constant pressure through the sampling component 1 made of soft materials, and maintain stability through the receiving container 2 made of hard materials.

[0042] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.
