Detailed Implementation
[0030] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0035] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0036] Accurate measurement of the viscosity characteristics of asphalt is crucial in the production and quality control of asphalt materials. The dynamic viscosity of asphalt is a key indicator for evaluating its flow properties at specific temperatures, especially the dynamic viscosity test at 60°C. This test typically requires a special glass vacuum-reducing capillary tube, ingeniously designed with a small diameter at one end and a curved lower end to accommodate the flow characteristics of asphalt.
[0037] However, this type of capillary tube faces a significant problem during use: the high viscosity and stickiness of asphalt cause it to form difficult-to-remove residues on the inner wall of the capillary. Traditional cleaning methods, such as manual brushing or simple rinsing, often fail to completely remove these residues, especially in the small diameter and bends of the capillary. This incomplete cleaning not only affects the accuracy of subsequent tests but may also lead to premature damage and scrapping of the capillary.
[0038] In one embodiment, referring to the accompanying drawings, a capillary cleaning device provided in this application is described. The capillary cleaning device provided in this application can effectively solve the above-mentioned problems, improve cleaning efficiency, reduce cleaning costs, and at the same time ensure the cleaning quality and service life of the capillary 4.
[0039] Reference manual attached Figure 1 and Figure 2 This application provides a capillary cleaning device, comprising a loading body 1, a top cover 2, and a fixing structure. The loading body 1 includes two chambers, a first chamber 110 and a second chamber 120, both of which have openings. The first chamber 110 is specifically used to hold a solvent capable of dissolving asphalt, while the second chamber 120 is used to hold a cleaning agent to remove residual solvent from the inner wall of the capillary 4. This compartmentalized design makes the cleaning process more efficient, as the solvent and cleaning agent can be used separately for different cleaning stages, ensuring thorough cleaning of the inner wall of the capillary 4.
[0040] The top cover 2 and the loading body 1 are detachably connected. This design facilitates opening and closing during the cleaning process, as well as maintenance and replacement. A fixing structure is provided on one side surface of the top cover 2 for mounting the capillary tube 4 to be cleaned. When the top cover 2 is tightly connected to the loading body 1, the capillary tube 4 can be completely immersed in the solvent in the first chamber 110 and the detergent in the second chamber 120, ensuring the comprehensiveness and thoroughness of the cleaning.
[0041] In practical implementation, the fixed structure is designed to be adjustable, accommodating capillary tubes 4 of different lengths and diameters, thus improving the versatility and flexibility of the device. Furthermore, suitable solvents and detergents can be selected based on the properties of the asphalt to ensure effective dissolution of the asphalt and removal of residues. The chamber volume of the loading body 1 is designed according to the specific dimensions of the capillary tube 4, ensuring that the capillary tube 4 can be completely submerged for optimal cleaning results.
[0042] To further improve cleaning efficiency, optionally, heating elements can be installed in the first chamber 110 and the second chamber 120 respectively to accelerate the dissolution process of asphalt by increasing the temperature of the solvent and detergent. Furthermore, this allows for the recycling of the solvent and detergent, reducing resource waste and environmental pollution.
[0043] In one embodiment, the loading body 1 and / or the top cover 2 are made of stainless steel. The stainless steel loading body 1 and top cover 2 can withstand repeated cleaning and disinfection processes without deformation or damage. This is crucial for ensuring the long-term stability and reliability of the capillary 4 cleaning device. Furthermore, the smooth surface of stainless steel reduces solvent and detergent residue, lowering the risk of cross-contamination during the cleaning process, while also facilitating cleaning and maintenance.
[0044] In specific implementations, the choice of stainless steel material can be adjusted according to the specific operating environment and requirements of the device. For example, different grades of stainless steel, such as 304 or 316 stainless steel, can be selected to suit solvents and detergents with different chemical properties. These grades of stainless steel have different corrosion resistance properties, and the most suitable material can be selected according to actual needs.
[0045] In one embodiment, based on the above embodiments, such as Figure 3 As shown, the fixing structure includes several hooks 31, which are spaced apart on one side surface of the top cover 2, providing multiple fixing points for the capillary tube 4, so that capillary tubes 4 of different lengths and diameters can be securely fixed in the device to meet various cleaning needs.
[0046] Each hook 31 is designed with a preset length. This design ensures that when the first chamber 110 or the second chamber 120 is filled with liquid (solvent, detergent), the end of the hook 31 is level with or below the liquid surface, which not only prevents liquid from overflowing, but also ensures that the capillary 4 can be completely immersed in the solvent or detergent during the cleaning process, thereby achieving a more thorough cleaning effect.
[0047] Furthermore, the preset length of the hook 31 can be adjusted according to the specific dimensions of the capillary tube 4. For example, the hook 31 has a telescopic structure, allowing its length to be adjusted according to the specific dimensions of the capillary tube 4. Specifically, the telescopic structure of the hook 31 includes a connecting tube that can slide axially and a matching pipe connector. In practical applications, when it is necessary to fix a shorter capillary tube 4, the hook 31 can retract to reduce its extended length; while for a longer capillary tube 4, it can extend to provide sufficient support.
[0048] In one embodiment, such as Figure 3As shown, each hook 31 has an adjusting portion 311 at its tail end, which is elastic. This design allows the hook 31 to not only secure the capillary tube 4 but also facilitate the loading and unloading of the capillary tube 4. In its natural state, the tail end of the hook 31 forms a closed loop through the bending of the adjusting portion 311. This closed loop secures the capillary tube 4, preventing it from falling off during cleaning. The closed loop design ensures the stability of the capillary tube 4 during cleaning and also protects it from damage.
[0049] It should be noted that the adjusting part 311 has elastic properties. In use, the adjusting part 311 can be manually deformed by the operator to open the closed loop, allowing the capillary tube 4 to be easily loaded and unloaded. This design simplifies the loading and unloading process of the capillary tube 4. The operator does not need to use additional tools or complicated operations; they can simply apply force to the adjusting part 311 to achieve quick loading and unloading of the capillary tube 4.
[0050] In one embodiment, each hook 31 has a mating strip at its starting point, and one side surface of the top cover 2 has a number of mating grooves adapted to the mating strips. The number of mating grooves is at least equal to the number of mating strips, ensuring that each hook 31 can be securely connected to the top cover 2.
[0051] The connecting strip and the connecting groove interlock, allowing the hook 31 to connect to the top cover 2. Simultaneously, the connecting strip can slide within the connecting groove to adjust the relative position of the hook 31. In this embodiment, the user can flexibly adjust the position of the hook 31 according to the specific location of the capillary 4 and cleaning requirements, achieving a personalized fixing solution. Furthermore, the sliding connection between the connecting strip and the connecting groove simplifies the installation and adjustment process of the hook 31, requiring no additional tools or complex operations; the user can quickly fix the capillary 4 in the appropriate position.
[0052] In practice, each docking groove extends outward from the center of the top cover 2, forming multiple regular groove-shaped structures on the top cover 2.
[0053] Based on the above embodiments, in one embodiment, it should be specifically noted that the loading body 1 includes two independent carriers, namely a first carrier 11 and a second carrier 12. A first chamber 110 is disposed within the first carrier 11 and is used to load solvent to dissolve the asphalt on the capillary 4; a second chamber 120 is disposed within the second carrier 12 and is used to load detergent to clean residual solvent. The top cover 2 is also designed as two independent parts, namely a first cover 21 and a second cover 22, which are used to close the openings of the first chamber 110 and the second chamber 120, respectively.
[0054] The first carrier 11 and the second carrier 12 are connected by a fixed connection to ensure the stability of the device; while the first cover 21 and the second cover 22 are set independently and can be opened or closed separately as needed, providing greater convenience for the operator.
[0055] Furthermore, the aforementioned fixing structure is disposed on the inner surface of the first cover 21, or simultaneously on the inner surfaces of both the first cover 21 and the second cover 22. When the fixing structure is only disposed on the inner surface of the first cover 21, the operator can remove the capillary tube 4 from the first chamber 110, then switch the positions of the first cover 21 and the second cover 22, using the first cover 21 to cover the second carrier 12, allowing the capillary tube 4 to be immersed in the detergent in the second chamber 120 to clean the solvent. This design allows the capillary tube 4 to be transferred between different chambers, achieving step-by-step cleaning. When the fixing structure is simultaneously disposed on the inner surfaces of both the first cover 21 and the second cover 22, the device can process two batches of capillary tubes 4 simultaneously, one batch soaked in solvent and the other cleaned in detergent, improving cleaning efficiency and operational flexibility.
[0056] In another embodiment, the loading body 1 is provided with a viewing area, the main function of which is to provide a direct observation window for the liquid level of the solvent or detergent, or to observe the asphalt dissolution on the capillary 4.
[0057] The visible area is typically made of a chemically resistant transparent material, such as polycarbonate or tempered glass. This material not only withstands the chemical attack of solvents and detergents but also provides a clear view, ensuring the operator can accurately observe the situation within the chamber. The size and shape of the visible area are adapted to the size and shape of the loading body 1 to ensure optimal observation.
[0058] In a specific embodiment, the visible area can be designed as one or more windows, which may be located on the side or top of the first carrier 11 and / or the second carrier 12. The edges of the windows may be fitted with rubber sealing rings to ensure that no solvent or detergent leakage occurs during observation. Furthermore, the surface of the visible area can be designed to be easy to clean to reduce the accumulation of stains and residues.
[0059] Optionally, a first handle 211 is provided on the outer surface of the first cover 21 for providing a retrieval position; similarly, a second handle 221 is also provided on the outer surface of the second cover 22 for providing a retrieval position. The design of these handles makes it more convenient and stable for the operator to pick up and move the top cover 2, especially when the top cover 2 needs to be opened and closed frequently for solvent and detergent replacement or inspection.
[0060] In a specific implementation, the handle can be made of the same material as the top cover 2, or a different material can be chosen to provide visual differentiation and tactile contrast. The handle can be round, oval, or any other shape suitable for gripping, and can be textured or grooved on the surface to enhance stability when gripping.
[0061] In one embodiment, the bottom of the first carrier 11 is provided with at least one outlet 111, and each outlet 111 is equipped with a valve. After the cleaning process is completed, by opening the valve, impurities such as asphalt deposited at the bottom of the first chamber 110 can be effectively discharged. This discharge mechanism not only simplifies the cleaning work after cleaning, but also helps to keep the solvent clean and avoid the reuse of impurities, thereby improving cleaning efficiency and solvent lifespan.
[0062] In addition, the valve can be designed to be manual or automatic to adapt to different operating environments and needs. In practical applications, the operator only needs to open the valve after cleaning is completed, and impurities such as asphalt can be smoothly discharged through the outlet 111. Then, the valve is closed to prepare for the next step of cleaning or solvent replacement.
[0063] Furthermore, the cleaning device also includes an infusion pump and a reservoir for storing solvent. At least one inlet 112 is provided at the upper or middle part of the first carrier 11. The output end of the infusion pump is connected to the inlet 112 via a pipeline, and the input end of the infusion pump is also connected to the reservoir via a pipeline. When the infusion pump is started, the solvent in the reservoir is automatically pumped into the first chamber 110 to replenish the solvent.
[0064] In this embodiment, this infusion system offers several advantages. First, it automates the solvent replenishment process, reducing the need for manual operation and improving ease of use and efficiency. Second, by precisely controlling the operation of the infusion pump, it ensures the accuracy and uniformity of solvent replenishment, avoiding over- or under-replenishment, thereby guaranteeing the consistency and reliability of the cleaning effect.
[0065] Meanwhile, the combined use of the infusion system and the aforementioned valve structure in this embodiment enables the thin-tube cleaning device to automatically complete the discharge and introduction of solvent. This automated operation not only improves cleaning efficiency and reduces the complexity of manual operation, but also lowers operating costs and potential safety risks, while also reducing solvent waste and environmental pollution.
[0066] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
