Description

Technical Field

[0001] This utility model relates to the field of dye cup technology, and in particular to a nozzle and dye cup inside a supercritical carbon dioxide anhydrous dyeing cup. Background Technology

[0002] Supercritical carbon dioxide anhydrous dyeing is a novel and environmentally friendly dyeing process. The dyeing process produces no wastewater. Before mass production, small-scale sampling is required to determine the dyeing process and effect. The dye cup is a high-pressure container used to hold the sample and fill it with carbon dioxide for dyeing. It consists of a cup body, a lid, and inflation and exhaust ports. After dyeing, the cup contains a significant amount of residual dye and oligomers, requiring cleaning. (Refer to...) Figure 10 As shown, the existing cleaning method uses supercritical carbon dioxide to be introduced through the air inlet 310 on the cup lid 300 and discharged from the outlet at the bottom of the cup body 200. This can blow out most of the residual dyes and oligomers, but a small amount of residue remains. Utility Model Content

[0003] The first objective of this invention is to provide an internal nozzle for a supercritical carbon dioxide anhydrous dyeing cup. This internal nozzle enables the airflow entering the dyeing cup to rotate tangentially downwards along the inner wall of the dyeing cup, effectively cleaning the residue on the inner wall of the dyeing cup.

[0004] The second objective of this invention is to provide a dyeing cup in which, when tilted, the airflow injected into the dyeing cup can rotate tangentially downwards along the inner wall of the dyeing cup, effectively cleaning the residue on the inner wall of the dyeing cup. Furthermore, the rotating airflow can also cause the fabric basket inside the dyeing cup to rotate together, resulting in a better cleaning effect on the dyed fabric and the fabric basket.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model discloses a nozzle inside a supercritical carbon dioxide anhydrous dyeing cup, including a nozzle body. One end of the nozzle body is connected to the air inlet of the dyeing cup. The nozzle body has a spray chamber communicating with the air inlet. One or more spray structures are arranged circumferentially around the spray chamber on the nozzle body. The airflow in the spray chamber rotates circumferentially along the spray chamber under the action of the spray structures and enters the internal space of the dyeing cup.

[0007] In some embodiments, the spraying structure includes a spraying hole, one end of which communicates with the spraying cavity and the other end of which communicates with the internal space of the dye cup, the spraying hole extending tangentially along the spraying cavity.

[0008] In some specific embodiments, the axis of the injection hole is inclined downward along the axial direction of the injection chamber, and the inclination angle is 10°-20°.

[0009] In some embodiments, the nozzle body is provided with at least one communicating hole, and the outer wall of the spray chamber is provided with at least one spray structure, and the spray structure is provided in a one-to-one correspondence with the communicating hole.

[0010] In some specific embodiments, the jet structure includes a guide vane, which is formed as an arc-shaped structure extending circumferentially along the jet cavity.

[0011] In some specific embodiments, the spraying structure includes a spray pipe that is connected to the communicating hole, and the spray pipe is formed as an arc-shaped structure extending circumferentially along the spraying cavity.

[0012] In some more specific embodiments, the axis of the opening at the end of the injection pipe away from the injection chamber is inclined downward along the axial direction of the injection chamber, and the inclination angle is 10°-20°.

[0013] In some embodiments, the bottom wall of the injection chamber is provided with a through hole.

[0014] This utility model also discloses a dyeing cup, including a cup body, a cup lid, a fabric basket, and the supercritical carbon dioxide anhydrous dyeing cup nozzle mentioned above. The fabric basket is installed inside the cup body, the cup lid is fastened to the upper end of the cup body, and the cup lid is provided with an air inlet hole. The supercritical carbon dioxide anhydrous dyeing cup nozzle is connected to the cup lid and is located inside the cup body.

[0015] In some embodiments, one end of the nozzle inside the supercritical carbon dioxide anhydrous dyeing cup is provided with a threaded section, the threaded section is connected to the air inlet, and a sealing gasket is provided between the cup cover and the nozzle inside the supercritical carbon dioxide anhydrous dyeing cup.

[0016] The beneficial effects of the supercritical carbon dioxide anhydrous dyeing cup inner nozzle of this utility model are as follows: In actual operation, the inner nozzle is installed on the cup lid of the dyeing cup, and then the cup lid is installed on the cup body. After the airflow enters the spray chamber from the air inlet of the dyeing cup, since at least one spray structure is arranged around the spray chamber on the nozzle body, the airflow after being sprayed out from the spray structure can rotate along the circumference of the spray chamber, so that the airflow can rotate tangentially downward along the inner wall of the dyeing cup, effectively cleaning the residue on the inner wall of the dyeing cup and improving the cleaning effect of the dyeing cup.

[0017] The beneficial effects of this invention's dyeing cup are as follows: Due to the aforementioned internal nozzle, during the actual cleaning process, after the airflow enters the spray chamber through the air inlet of the dyeing cup, at least one spray structure is arranged circumferentially around the spray chamber on the nozzle body. The airflow ejected from the spray structure can rotate circumferentially along the spray chamber, allowing the airflow to rotate tangentially downwards along the inner wall of the dyeing cup, effectively cleaning the residue on the inner wall of the dyeing cup and improving the cleaning effect on the dyeing cup. Furthermore, the rotating airflow can also drive the fabric basket inside the dyeing cup to rotate together, resulting in a better cleaning effect on the dyed fabric and the fabric basket.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between 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.

[0034] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] This utility model discloses an internal nozzle for a supercritical carbon dioxide anhydrous dyeing cup (hereinafter referred to as the internal nozzle for ease of description), referenced... Figures 1-6As shown, the device includes a nozzle body 100, one end of which is connected to the air inlet 310 of the dyeing cup. The nozzle body 100 has a spray chamber 110 communicating with the air inlet 310. At least one spray structure is circumferentially arranged on the nozzle body 100 surrounding the spray chamber 110. The airflow in the spray chamber 110 rotates circumferentially along the spray chamber 110 under the action of the spray structure and enters the internal space of the dyeing cup. It can be understood that in actual operation, the inner nozzle is installed on the cup lid 300 of the dyeing cup, and then the cup lid 300 is installed on the cup body 200. After the airflow enters the spray chamber 110 from the air inlet 310 of the dyeing cup, because at least one spray structure is circumferentially arranged on the nozzle body 100 surrounding the spray chamber 110, the airflow ejected from the spray structure can rotate circumferentially along the spray chamber 110, allowing the airflow to rotate tangentially downwards along the inner wall of the dyeing cup (see reference). Figure 11 As shown in the image, this effectively cleans the residue on the inner wall of the dye cup, improving the cleaning effect.

[0036] The following is based on Figures 1-9 The structure of the inner nozzle of six specific embodiments of this utility model is introduced.

[0037] Example 1:

[0038] refer to Figures 1-2 As shown, the spray structure includes a spray hole 120. One end of the spray hole 120 communicates with the spray cavity 110, and the other end communicates with the internal space of the dye cup. The spray hole 120 extends tangentially along the spray cavity 110. It can be understood that during actual operation, after the airflow enters the spray cavity 110, it can be sprayed out through the spray hole 120. Since the spray hole 120 extends tangentially along the spray cavity 110, the airflow, after exiting the inner nozzle, can rotate circumferentially along the inner nozzle, and then tangentially rotate downwards along the inner wall of the dye cup, thereby improving the cleaning effect on the dye cup. Optionally, in this embodiment, the number of spray holes 120 is three, and they are evenly spaced circumferentially along the spray cavity 110. In other embodiments of this utility model, the number of spray holes 120 can be selected according to actual needs.

[0039] Optionally, the axis of the spray hole 120 is inclined downwards along the axial direction of the spray chamber 110. It can be understood that by forming the spray hole 120 as an inclined hole, the airflow has a larger angle of inclination along the cup wall during airflow, allowing the airflow to reach the bottom of the cup 200 more quickly and with less velocity at the bottom. This ensures the lower part of the cup wall is also cleaned effectively, thus improving the cleaning effect on the dyed cup. Further optionally, the inclination angle is 10°-20°. Specifically, the inclination angle can be 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, or 20°. Of course, other values ​​or ranges within the 10°-20° range can also be selected according to actual needs.

[0040] Optionally, the nozzle body 100 is provided with a threaded section 160 and a cylindrical section 170. The threaded section 160 is threadedly connected to the air inlet 310, and the diameter of the cylindrical section 170 is larger than the diameter of the threaded section 160. During actual installation, the threaded section 160 is inserted into the air inlet 310, and the entire nozzle body 100 is rotated. Rotation stops when either the cylindrical section 170 or the threaded section 160 abuts against the cup cover 300 of the dye cup. This facilitates the assembly of the nozzle body 100 and the dye cup while also improving the installation stability of the nozzle body 100 on the cup cover 300. Further, optionally, the direction of the threaded section 160 is the direction of the reaction force of the spray from the spray hole 120. Therefore, during actual operation, the reaction force of the airflow on the nozzle body 100 can be prevented from loosening the threaded fit.

[0041] Optionally, the ratio of the orifice area of ​​the injection chamber 110 to the orifice area of ​​the injection hole 120 is 10-100. This can improve the airflow velocity and the uniformity of the injection.

[0042] Alternatively, the cylindrical segment 170 can be replaced by a square prism, hexagonal prism, or other prism shape.

[0043] Optionally, a sealing gasket can be provided at the contact portion between the threaded section 160 or the cylindrical section 170 and the cup lid 300 to increase the sealing performance.

[0044] Example 2:

[0045] refer to Figures 3-4As shown, the nozzle body 100 is provided with at least one connecting hole 130, and the outer wall of the spray chamber 110 is provided with at least one spray structure, with each spray structure corresponding to one of the connecting holes 130. The spray structure includes a guide vane 140, which is formed as an arc-shaped structure extending circumferentially along the spray chamber 110. It is understood that during actual operation, after the airflow enters the spray chamber 110, it can be ejected from the connecting hole 130. Since the spray structure includes the guide vane 140, after the airflow exits the connecting hole 130, it rotates circumferentially along the inner nozzle under the guidance of the guide vane 140, and then rotates tangentially downwards along the inner wall of the dye cup, thereby improving the cleaning effect on the dye cup. Optionally, in this embodiment, the number of connecting holes 130 is three, and they are evenly spaced along the circumference of the spray chamber 110. Correspondingly, there are also three guide vanes 140. In other embodiments of this utility model, the number of connecting holes 130 and guide vanes 140 can be selected according to actual needs.

[0046] Optionally, the axis of the connecting hole 130 is inclined downwards along the axial direction of the spray chamber 110. It can be understood that by forming the connecting hole 130 as an inclined hole, the airflow has a larger angle of inclination along the cup wall during airflow, allowing the airflow to reach the bottom of the cup 200 more quickly and with less velocity at the bottom. This ensures the lower part of the cup wall is also cleaned, thus improving the cleaning effect on the dyed cup. Further optionally, the inclination angle is 10°-20°. Specifically, the inclination angle can be 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, or 20°. Of course, other values ​​within the 10°-20° range, or other ranges, can be selected according to actual needs.

[0047] Optionally, the ratio of the orifice area of ​​the injection chamber 110 to the orifice area of ​​the connecting hole 130 is 10-100. This can improve the airflow velocity and the uniformity of the injection.

[0048] Optionally, the nozzle body 100 is provided with a threaded section 160, a disc section 180, and a prism section 190 connected in sequence. The threaded section 160 is threadedly connected to the air inlet 310, and the diameter of the disc section 180 is larger than the diameter of the threaded section 160. A guide vane 140 is disposed on the prism section 190. During actual installation, the threaded section 160 is inserted into the air inlet 310, and the entire nozzle body 100 is rotated. Rotation stops when either the disc section 180 or the threaded section 160 abuts against the cup cover 300 of the dye cup. This facilitates the assembly of the nozzle body 100 and the dye cup while also improving the installation stability of the nozzle body 100 on the cup cover 300. Distributing the guide vane 140 on the prism section 190 and connecting it to the side of the disc section 180 opposite to the threaded section 160 enhances the stability of the guide vane 140 and ensures its guiding effect on the airflow.

[0049] Alternatively, the direction of the threaded section 160 may be the direction of the reaction force of the jet from the jet hole 120. This avoids the phenomenon of the airflow loosening the threaded fit on the nozzle body 100 during actual operation.

[0050] Example 3:

[0051] refer to Figures 5-6 As shown, the nozzle body 100 is provided with at least one connecting hole 130, and the outer wall of the spray chamber 110 is provided with at least one spray structure, with each spray structure corresponding to one of the connecting holes 130. The spray structure includes a spray pipe 150, which is connected to the connecting hole 130. The spray pipe 150 is formed as an arc-shaped structure extending circumferentially along the spray chamber 110. It can be understood that during actual operation, after the airflow enters the spray chamber 110, it can be ejected from the connecting hole 130. Since the spray structure includes the spray pipe 150, the airflow exits the connecting hole 130 and enters the spray pipe 150, then is sprayed into the interior of the dye cup. Because the spray pipe 150 is formed as an arc-shaped structure extending circumferentially along the spray chamber 110, the airflow, after exiting the spray pipe 150, can rotate circumferentially along the inner nozzle, and then tangentially rotate downwards along the inner wall of the dye cup, thereby improving the cleaning effect on the dye cup. Optionally, in this embodiment, the number of connecting holes 130 is three, and they are evenly spaced along the circumference of the injection chamber 110. Correspondingly, there are also three injection pipes 150. In other embodiments of this utility model, the number of connecting holes 130 and injection pipes 150 can be selected according to actual needs.

[0052] Optionally, the axis of the opening 151 at the end of the spray pipe 150 away from the spray cavity 110 is inclined downwards along the axial direction of the spray cavity 110. This means that the opening 151 at the end of the spray pipe 150 away from the spray cavity 110 is formed as an inclined opening. During airflow, this allows the airflow to have a larger angle of inclination along the cup wall, enabling the airflow to reach the bottom of the cup 200 more quickly. This also reduces the velocity drop-off at the bottom of the cup 200, ensuring the lower part of the cup wall is thoroughly cleaned, thus improving the cleaning effect on the dyed cup. Further optionally, the inclination angle is 10°-20°. Specifically, the inclination angle can be 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, or 20°. Of course, other values ​​or ranges within the 10°-20° range can also be selected according to actual needs.

[0053] Optionally, the nozzle body 100 is provided with a threaded section 160 and a prismatic section 190 connected in sequence. The threaded section 160 is threadedly connected to the air inlet 310, and the spray pipe 150 is located on the prismatic section 190. In actual installation, the threaded section 160 is inserted into the air inlet 310, and the entire nozzle body 100 is rotated to complete the installation. This facilitates the assembly of the nozzle body 100 and the dye cup, while also improving the installation stability of the nozzle body 100 on the cup cover 300. Setting the spray pipe 150 on the prismatic section 190 ensures the stability of the spray pipe 150, thereby facilitating the airflow to enter the spray pipe 150 from the connecting hole 130 and then spray out into the dye cup.

[0054] Alternatively, the direction of the threaded section 160 may be the direction of the reaction force of the jet from the jet hole 120. This avoids the phenomenon of the airflow loosening the threaded fit on the nozzle body 100 during actual operation.

[0055] Optionally, the ratio of the orifice area of ​​the injection chamber 110 to the orifice area of ​​the connecting hole 130 is 10-100. This can improve the airflow velocity and the uniformity of the injection.

[0056] Example 4:

[0057] refer to Figure 7 As shown, the internal nozzle of this embodiment has a structure that is roughly the same as that of Embodiment 1. The difference is that the bottom of the spray chamber 110 of the internal nozzle of this embodiment is provided with a through hole 111.

[0058] Example 5:

[0059] refer to Figure 8 As shown, the internal nozzle of this embodiment has a structure that is roughly the same as that of embodiment two. The difference is that the bottom of the spray chamber 110 of the internal nozzle of this embodiment is provided with a through hole 111.

[0060] Example 6:

[0061] refer to Figure 9 As shown, the internal nozzle of this embodiment has a structure that is roughly the same as that of embodiment three. The difference is that the bottom of the spray chamber 110 of the internal nozzle of this embodiment is provided with a through hole 111.

[0062] This utility model also discloses a dye cup, for reference. Figure 11 As shown, the dyeing cup includes a cup body 200, a cup lid 300, a fabric basket 400, and the aforementioned inner nozzle. The fabric basket 400 is installed inside the cup body 200, and the cup lid 300 is fastened to the upper end of the cup body 200. The cup lid 300 is provided with an air inlet 310. The inner nozzle of the supercritical carbon dioxide anhydrous dyeing cup is connected to the cup lid 300 and is located inside the cup body 200. Understandably, due to the aforementioned internal nozzle, during the actual cleaning process, after the airflow enters the spray chamber 110 through the air inlet 310 of the cup cover 300, the airflow can rotate circumferentially along the spray chamber 110 after being ejected from the spray structure, because at least one spray structure is arranged around the spray chamber 110 on the nozzle body 100. This allows the airflow to rotate tangentially downward along the inner wall of the dye cup, effectively cleaning the residue on the inner wall of the dye cup and improving the cleaning effect on the dye cup. Furthermore, the rotating airflow can also drive the fabric basket 400 inside the dye cup to rotate together, resulting in a better cleaning effect on the dyed fabric and the fabric basket 400.
