Description

Technical Field

[0001] The utility model belongs to the technical field of carbon fibers, and in particular relates to a nozzle and an ammoniazing device for carbon fiber polymerization liquid. Background Art

[0002] Carbon fiber is an inorganic polymer fiber with a carbon content of more than 90%. It is a microcrystalline graphite material obtained by carbonizing and graphitizing organic fibers, such as acrylic yarn, asphalt and viscose fibers, in an inert gas. Carbon fiber has many excellent mechanical properties. Compared with metal materials such as titanium, steel, and aluminum, it has the inherent nature of carbon materials and the softness and processability of textile fibers. It has many excellent properties such as high strength, high modulus, high temperature resistance, corrosion resistance, fatigue resistance, creep resistance, electrical conductivity, heat transfer, and a small thermal expansion coefficient. It is widely used in military fields such as aircraft manufacturing, aerospace, and missile rockets, industrial fields such as wind power blades and automobile manufacturing, and sports and leisure fields such as golf clubs, badminton rackets and bicycles. Although carbon fiber has excellent performance, it is difficult to use it alone. It is necessary to polymerize carbon fibers to form composite materials for use;

[0003] In the production of carbon fiber polymer liquid, the carbon fiber polymer liquid needs to be ammoniation treated to keep the pH value of the carbon fiber polymer liquid between 6 and 7. In the existing technology, the carbon fiber polymer liquid is ammoniation treated by a simple homemade nozzle, which may cause nozzle clogging and uneven nozzle air outlet, making the ammoniation effect fail to meet the use requirements. If the nozzle is frequently replaced, it will cause material loss and increase the amination cost.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

Therefore, they cannot be understood as limitations on the present invention.

[0048] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0049] like Figure 1 、 Figure 2 and Figure 4 As shown, the utility model provides a nozzle, comprising:

[0050] An outer sleeve 11 and an inner sleeve 12 fitted on the inner side of the outer sleeve 11;

[0051] At least two jet areas are arranged circumferentially on the peripheral wall of the outer sleeve 11, and each jet area includes a plurality of jet holes 111;

[0052] The inner sleeve 12 is provided with at least two air outlet holes 121 corresponding to the air jet areas.

[0053] The radial projection of each air outlet 121 on the peripheral wall of the outer sleeve 11 covers the corresponding air injection area.

[0054] In an embodiment of the present invention, at least two air outlet holes 121 are provided on the inner sleeve 12 of the nozzle 1 and at least two air jet areas are provided on the outer sleeve 11, each air jet area includes a plurality of air jet holes 111, so that the nozzle 1 can discharge air evenly, thereby enabling the ammoniazing effect to meet the use requirements, and the double-layer tubular structure formed by the inner sleeve 12 and the outer sleeve 11 can enhance the structural strength of the nozzle 1.

[0055] The inner sleeve 12 is fitted on the inner side of the outer sleeve 11 to form a double-layer tubular structure. That is, there is no gap between the inner sleeve 12 and the outer sleeve 11, and no gas flows through them.

[0056] Each jet area includes a plurality of jet holes 111, and these jet holes 111 are used to eject gas or fluid. For example, these jet holes 111 are used to eject ammonia used for ammonia of carbon fiber polymer liquid.

[0057] The radial projection of each gas outlet 121 on the peripheral wall of the outer sleeve 11 covers the corresponding jet area, so that the gas entering the inner sleeve 12 enters the corresponding jet area through the gas outlet 121 and is ejected from the plurality of jet holes 111, achieving uniform gas ejection.

[0058] The radial direction and axial direction mentioned in this article refer to the radial direction and axial direction of the outer sleeve respectively.

[0059] The radial projection of each air outlet 121 on the peripheral wall of the outer sleeve 11 covers the corresponding air injection area. It can also be understood that the radial projection of each air injection hole 111 in the air injection area on the peripheral wall of the inner sleeve is located in the area where the air outlet 121 is located.

[0060] In the embodiment of the present invention, each jet area includes a plurality of jet holes 111 arranged in a row along the axial direction;

[0061] Each air outlet hole 121 is an elongated hole extending along the axial direction.

[0062] In an embodiment of the present invention, specifically, the plurality of jet holes 111 in each jet area are linearly arranged along the axial direction of the outer sleeve 11, so that the outer sleeve 11 is provided with at least two rows of jet holes 111 arranged along the circumferential direction; the specific number and spacing of the jet holes 111 can be adjusted according to actual needs to achieve the desired gas or liquid distribution effect.

[0063] Each air outlet 121 is an elongated hole extending axially. This design allows the air outlet 121 to have a certain length in the axial direction, so as to better cover the corresponding jetting area, ensure the uniformity of gas or liquid ejection, and enable the nozzle 1 to emit air uniformly.

[0064] To further ensure uniformity in the ejection of gas or liquid, the two jet regions have the same number of jet holes 111. For example, the two jet regions are respectively a first jet region and a second jet region. The first jet region is provided with four first jet holes 111a arranged in a row along the axial direction, and the second jet region is provided with four second jet holes 111b arranged in a row along the axial direction. The first jet holes 111a and the second jet holes 111b are circumferentially positioned one-to-one with each other without any overlap. It can be understood that one first jet hole 111a and one second jet hole 111b are provided on the same circumferential surface of the outer sleeve 11. The inner sleeve 12 is provided with a first gas outlet hole 121a and a second gas outlet hole 121b on the circumferential wall. The radial projection of the first gas outlet hole 121a on the circumferential wall of the outer sleeve covers the jet region formed by the four first gas outlet holes 111a, and the radial projection of the second gas outlet hole 121b on the circumferential wall of the outer sleeve covers the jet region formed by the four second gas outlet holes 111b.

[0065] Furthermore, if Figure 3As shown, the outer sleeve 11 is a circular tube. The two jet holes 111 located in the same circumferential surface of the outer sleeve 11 have a first connecting line and a second connecting line respectively connected to the center of the circumferential surface of the outer sleeve 11. The angle between the first connecting line and the second connecting line is 60°. For example, if the circumferential surface of the outer sleeve 11 is regarded as a clock face, with the first jet hole 111a located at "12 o'clock", the second jet hole 111b can be located at "2 o'clock".

[0066] This design can optimize the jetting efficiency, improve the uniformity of gas or liquid jetting, and more accurately control the direction and intensity of the airflow or fluid jetting; at the same time, it makes the nozzle 1 less likely to be blocked by the carbon fiber polymer liquid.

[0067] In the embodiment of the present invention, one end of the inner sleeve 12 and the outer sleeve 11 are respectively closed ends, and the other ends are respectively open ends;

[0068] The closed end 122 of the inner sleeve is inserted into the outer sleeve 11 through the open end 113 of the outer sleeve;

[0069] The air outlet 121 is disposed near the closed end 122 of the inner sleeve, and the air injection hole 111 is disposed near the closed end 112 of the outer sleeve.

[0070] In an embodiment of the present invention, during installation, the closed end 122 of the inner sleeve is inserted into the outer sleeve 11 through the open end 113 of the outer sleeve, the outer peripheral wall of the inner sleeve 12 is fitted with the outer peripheral wall of the outer sleeve 11, and the closed end 122 of the inner sleeve is fitted with the closed end of the outer sleeve, so that the inner sleeve 12 is completely surrounded by the outer sleeve 11, forming a nested structure.

[0071] The air outlet 121 is arranged on the inner sleeve 12 and is close to its closed end, which means that the gas or liquid flows out from the closed end 122 close to the inner sleeve; the jet hole 111 is arranged on the outer sleeve 11 and is close to its closed end, which means that the gas or liquid is ejected from the closed end 112 close to the outer sleeve; at the same time, the air outlet 121 and the jet hole 111 can be easily extended into other pipelines, for example, into the following second pipeline 6 that supplies carbon fiber polymerization liquid.

[0072] Furthermore, an inner sealing ring 124 coaxial with the inner sleeve 12 is provided on the outer peripheral wall of the open end of the inner sleeve 12; an outer sealing ring 114 coaxial with the outer sleeve 11 is provided on the outer peripheral wall of the open end of the outer sleeve 11; the end surface of the inner sealing ring 124 abuts against the end surface of the outer sealing ring 114;

[0073] An inner sealing ring 124 is provided on the outer circumferential wall of the open end 123 of the inner sleeve, coaxial with the inner sleeve 12. This inner sealing ring 124 may be an annular protrusion or an additional annular component. Its primary purpose is to provide a sealing surface for contact with a component on the outer sleeve 11, thereby achieving a sealing effect. Similarly, an outer sealing ring 114 is also provided on the outer circumferential wall of the open end 113 of the outer sleeve, coaxial with the outer sleeve 11. This outer sealing ring 114 functions similarly to the inner sealing ring 124, also providing a sealing surface. When the inner sleeve 12 is inserted into the outer sleeve 11, the end surface of the inner sealing ring 124 abuts the end surface of the outer sealing ring 114, forming a sealing interface that effectively prevents gas or liquid from entering the gap that may exist between the inner sleeve 12 and the outer sleeve 11, or enhances the sealing between the nozzle 1 and the first pipeline 3 described below, preventing gas or liquid from leaking through the gap between the first pipeline 3 and the nozzle 1.

[0074] Because both inner and outer sealing rings 124 and 114 are coaxially arranged with their respective pipes, they provide stable support and positioning, maintaining the relative position between inner and outer sleeves 12 and 11. Sealing rings are typically made of wear-resistant and corrosion-resistant materials, allowing them to withstand certain pressures and friction, extending the service life of the entire system. Outer sealing ring 114 may be made of polytetrafluoroethylene.

[0075] In addition, the radial dimension of the inner sealing ring 124 is greater than that of the outer sealing ring 114 , so that the outer periphery of the inner sealing ring 124 is flush with the outer periphery of the outer sealing ring 114 after the inner sealing ring 124 abuts against the outer sealing ring 114 .

[0076] Furthermore, the outer sleeve 11 and the inner sleeve 12 are made of different materials, the inner sleeve 12 is a steel pipe, and the outer sleeve 11 is a polytetrafluoroethylene tube;

[0077] The inner casing 12 is made of steel, which offers numerous advantages, including high strength, good rigidity, and corrosion resistance. These properties enable steel to withstand significant pressure and weight while maintaining structural stability and durability. Steel is an ideal choice for applications requiring high pressure or temperature resistance.

[0078] The outer sleeve 11 is made of polytetrafluoroethylene (PTFE), a high-performance plastic material with excellent corrosion and heat resistance and low friction. It maintains stable performance under extreme environmental conditions and is non-reactive with most chemicals. Furthermore, PTFE tubing offers excellent flexibility and plasticity, allowing it to adapt to a variety of complex shapes and sizes.

[0079] The low friction of the polytetrafluoroethylene tube can reduce the resistance of gas or liquid in the pipeline, thereby improving the flow efficiency of the fluid and the overall efficiency of the system; and can reduce the residue of gas or liquid on the outer sleeve 11, thereby avoiding the carbon fiber polymer liquid from clogging the jet hole 111, making the size of the jet hole 111 relatively small, and thus making the jet intensity of the jet hole 111 stronger.

[0080] like Figure 5 and Figure 6 As shown, the present invention also provides an ammoniacing device for carbon fiber polymer liquid, comprising: an ammonia cylinder 2, a first pipeline 3, a mixer 6, a feed pump 4, a second pipeline 6 for conveying carbon fiber polymer liquid, and a storage tank 7 for storing ammoniacing products;

[0081] The feed pump 4, the mixer 6 and the storage tank 7 are sequentially connected in series to the second pipeline 6;

[0082] The air inlet end of the first pipeline 3 is connected to the ammonia cylinder 2, and the air outlet end is installed with a nozzle 1;

[0083] All the air outlet holes 121 and the air injection holes 111 of the nozzle 1 extend into the second pipeline 6 between the feed pump 4 and the mixer 6 .

[0084] In an embodiment of the present utility model, the first pipeline 3 transports ammonia from the ammonia bottle 2 to the nozzle 1, and the ammonia is ejected from the jet hole 111 through the gas outlet 121 to the second pipeline 6. At the same time, the feed pump 4 pumps the carbon fiber polymer liquid into the second pipeline 6, and the ammonia is ejected into the carbon fiber polymer liquid by the jet hole 111. The ammonia and the carbon fiber polymer liquid are mixed in the mixer 6 to undergo an amination reaction to form an ammoniated product of the carbon fiber polymer liquid, and the ammoniated product is finally transported and stored in the storage tank 7.

[0085] Furthermore, the inner sleeve 12 and the open end 113 of the outer sleeve, the inner sealing ring 124 and the outer sealing ring 114 are inserted and installed in the gas outlet end of the first pipeline 3;

[0086] The inner sleeve 12 and the closed end 112 of the outer sleeve are inserted into the second pipeline 6 so that all the air injection holes 111 and the air outlet holes 121 extend into the second pipeline 6 .

[0087] The inner sealing ring 124 and the outer sealing ring 114 are inserted into the gas outlet end of the first pipeline 3. Specifically, the outer periphery of the inner sealing ring 124 and the outer periphery of the outer sealing ring 114 fit the inner periphery of the first pipeline 3, thereby improving the sealing between the nozzle 1 and the first pipeline 3.

[0088] After the open ends 113 of the inner sleeve 12 and the outer sleeve, the inner sealing ring 124 and the outer sealing ring 114 are inserted into the gas outlet end of the first pipeline 3, the inner sleeve 12 and the outer sleeve 11 are installed with the first pipeline 3 through the flange.

[0089] The closed ends 112 of the inner sleeve 12 and the outer sleeve are inserted into the second pipe 6, ensuring that all the injection holes 111 and the air outlet holes 121 extend into the second pipe 6 while making the length of the inner sleeve 12 and the outer sleeve 11 inserted into the second pipe 6 relatively short, thereby facilitating the disassembly and installation of the nozzle 1.

[0090] Specifically, the first pipeline 3 has a horizontal section 31 and the second pipeline 6 has a vertical section 61;

[0091] The mixer 6 is connected in series to the vertical section 61 and is located above the feed pump 4;

[0092] The inner sleeve 12 and the outer sleeve 11 extend horizontally;

[0093] The inner sleeve 12 and the open end 113 of the outer sleeve, the inner sealing ring 124 and the outer sealing ring 114 are inserted and installed in the gas outlet end of the second horizontal section 31;

[0094] The closed ends 112 of the inner sleeve 12 and the outer sleeve are inserted into the vertical section 61 through the through holes provided on the outer peripheral wall of the vertical section 61 . The air injection holes 111 and the air outlet holes 121 are provided upward in the vertical section 61 .

[0095] The arrangement of the horizontal section 31 and the vertical section 61 can reduce resistance to the flow of ammonia and carbon fiber polymer solution. The mixer 6 is connected in series to the vertical section 61 and is located above the feed pump 4, enabling the carbon fiber mixture to flow from bottom to top in the second pipeline 6.

[0096] Combined with attachment Figure 5 The closed ends 112 of the inner sleeve 12 and the outer sleeve are inserted into the second pipeline 6 from left to right, and the air outlet 121 and the air injection hole 111 spray ammonia upward. The carbon fiber polymer liquid in the second pipeline 6 flows from bottom to top, and the direction of ammonia spraying follows the flow direction of the carbon fiber polymer liquid, which can prevent the carbon fiber polymer liquid from splashing when the ammonia and the carbon fiber polymer liquid are combined, thereby achieving sufficient mixing of the ammonia and the carbon fiber polymer liquid and improving the ammonia effect.

[0097] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above-mentioned technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
