Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sampling device technology, and in particular relates to a layered sampling device for detecting single-walled carbon nanotube slurry. Background Technology
[0002] In the research and production of single-walled carbon nanotube slurries, the slurry's stratification stability is a core indicator affecting conductivity and dispersibility. Conventional slurry stability testing involves storing the slurry in sample vials; after settling, the slurry will stratify. At this point, a dropper is used to extract samples from the top, middle, and bottom layers for testing. However, when extracting samples from the middle or bottom layers, the upper and middle layers tend to adhere to the dropper wall, causing cross-contamination between the different layers and leading to inaccurate slurry stability tests.
[0003] Therefore, how to avoid inaccurate stability testing of single-walled carbon nanotube slurries due to cross-contamination between different layers is a technical problem that urgently needs to be solved by those skilled in the art.
[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content
[0005] This disclosure provides at least one layered sampling device for detecting single-walled carbon nanotube slurry.
[0006] In a first aspect, embodiments of this disclosure provide a layered sampling device for detecting single-walled carbon nanotube slurry, comprising: a cylinder, the cylinder wall of which is made of a transparent material, for storing slurry samples;
[0007] Several sampling channels are arranged in an array along the height direction of the cylinder, and the sampling channels penetrate the cylinder wall and form concave ports on the inner side of the cylinder.
[0008] A sealing cover plate, which is hinged to the recessed port via a hinge shaft;
[0009] The sealing cover is normally in a closed state; and
[0010] When the sealing cover is subjected to radial thrust by the drip tube, it rotates around the hinge axis to release the sealing state.
[0011] In one alternative embodiment, the sampling channel has a progressively tapering conical cross-section, with its concave port opening outward in a funnel shape.
[0012] In one optional embodiment, a hinge seat is provided on the concave port, and the sealing cover is hinged to the hinge seat of the concave port via a hinge shaft.
[0013] In one alternative implementation, the spacing between adjacent sampling channels is 5-10 mm.
[0014] In one alternative embodiment, the sampling channel extends into the cylinder to a height that is 1-2 times the thickness of the cylinder wall.
[0015] In one optional embodiment, a groove is provided on the concave port, and a sealing ring is provided in the groove.
[0016] Secondly, embodiments of this disclosure also provide a stratified sampling device, comprising:
[0017] The cylinder, with its walls made of transparent material, is used to store slurry samples;
[0018] Several sampling channels are arranged in an array along the height direction of the cylinder, and the sampling channels penetrate the cylinder wall and form concave ports on the inner side of the cylinder.
[0019] A sealing assembly is movably fitted into the recessed port of each sampling channel;
[0020] The sealing assembly is normally in a closed state;
[0021] When the sealing assembly is subjected to a radial force, the sealing state is released.
[0022] In one alternative embodiment, the sealing assembly includes a sealing cover plate hinged to the recessed port via a hinge shaft.

[0042] Research has revealed a drawback of existing technologies: conventional slurry stability testing involves storing the slurry in sample bottles. After settling, the slurry separates into layers, and a dropper is used to extract samples from the top, middle, and bottom layers for testing. However, when the dropper extracts samples from the middle or bottom layer, the samples from the top and middle layers tend to adhere to the dropper wall, causing cross-contamination between the different layers and resulting in inaccurate slurry stability testing.
[0043] Based on the above research, this disclosure provides a layered sampling device for detecting single-walled carbon nanotube slurry. The device takes samples from the sampling channel on the side of the cylinder through a dropper. The dropper only contacts the slurry sample of the target layer, thus avoiding cross-contamination between the slurry samples of different layers and solving the above-mentioned problems.
[0044] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.
[0045] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0046] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0047] See Figure 1 and Figure 2This disclosure provides a layered sampling device for detecting single-walled carbon nanotube slurry, comprising: a cylindrical body 100, the wall of which is made of transparent material, and the interior of the cylindrical body 100 is suitable for storing slurry samples. A plurality of sampling channels 200 are provided on the side wall of the cylindrical body 100, and the sampling channels 200 are arranged in an array along the height direction of the cylindrical body 100. The sampling channels 200 penetrate the side wall of the cylindrical body 100 and form a concave port 210 inside the cylindrical body 100; a sealing cover plate 310 is hinged to the concave port 210, and the sealing cover plate 310 is normally in a closed state to prevent the slurry sample inside the cylindrical body 100 from flowing out. After the slurry samples inside the cylinder 100 have settled and separated into layers, the dropper 400 is simply inserted into the sampling channels 200 corresponding to the upper layer 101, middle layer 102, and lower layer 103 slurry samples, respectively. The dropper 400 is adapted to apply radial thrust to the sealing cover plate 310. Under the action of radial thrust, the sealing cover plate 310 rotates around the hinge axis 311. At this time, the sampling channel 200 is connected to the inside of the cylinder 100, and the sealing state is released. The dropper 400 is adapted to pass through the concave port 210 of each sampling channel 200 to draw up the slurry samples of the upper layer 101, middle layer 102, and lower layer 103, respectively. Through the above settings, the dropper 400 only contacts the slurry sample of the target layer, and will not cause cross-contamination of the slurry samples of different layers, thereby avoiding inaccurate slurry stability testing.
[0048] See also Figure 1 In some embodiments, the sampling channel 200 has a gradually tapering conical cross-section, with its concave port 210 opening outward in a funnel shape. The larger cross-sectional area of the outer port 220 facilitates insertion of the dropper 400 and makes operation easier; while using the smaller cross-sectional area of the concave port 210 reduces leakage of the slurry sample when the dropper 400 is sampling.
[0049] See Figure 3 and Figure 4 In some embodiments, a hinge seat 211 is provided on the concave port 210, and the sealing cover plate 310 is hinged to the hinge seat 211 of the concave port 210 via the hinge shaft 311.
[0050] See also Figure 1 In some embodiments, the spacing between adjacent sampling channels 200 is 5-10 mm, preferably 8 mm.
[0051] See also Figure 1 In some embodiments, the sampling channel 200 extends into the cylinder 100 to a height that is 1-2 times the wall thickness of the cylinder 100. When the slurry is left to stand, some slurry will remain on the outer wall of the sampling channel 200. This design prevents the sampling channel 200 from extending too far into the cylinder 100, thereby reducing the amount of slurry remaining on the outer wall of the sampling channel 200.
[0052] See Figure 5In some embodiments, a groove 212 is provided on the recessed port 210, and a sealing ring 213 is provided in the groove 212. When the sealing cover plate 310 is in the closed state, the sealing ring 213 abuts against the cover plate, which can increase the sealing performance and prevent slurry leakage.
[0053] See Figure 1 Some embodiments provide a layered sampling device, including: a cylinder 100, the cylinder wall of which is made of transparent material for storing slurry samples; a plurality of sampling channels 200 arranged in an array along the height direction of the cylinder 100, wherein the sampling channels 200 penetrate the cylinder wall and form concave ports 210 on the inner side of the cylinder 100; and a sealing assembly 300 movably assembled to the concave ports 210 of each sampling channel 200; wherein the sealing assembly 300 is in a closed state under normal conditions; and the sealing assembly 300 is released from the closed state when subjected to radial force.
[0054] See also Figure 1 In some embodiments, the sealing assembly 300 includes a sealing cover 310 hinged to the recessed port 210 via a hinge shaft 311. When the sealing cover 310 is subjected to a radial force, it is adapted to rotate about the hinge shaft 311 to release the seal.
[0055] In summary, this stratified sampling device for single-walled carbon nanotube slurry testing utilizes an array of sampling channels 200 arranged axially along the side wall of the cylinder 100. After the slurry sample inside the cylinder 100 is stratified, during sampling, the dropper 400 is inserted into the sampling channel 200 corresponding to the target layer, and the sealing cover 310 is opened to obtain the slurry sample within the target layer. This avoids cross-contamination of the upper, middle, and lower slurry samples, thereby preventing inaccurate slurry stability testing.
[0056] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0057] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0058] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0059] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0060] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
