Description

Technical Field

[0001] The utility model belongs to the technical field of carbon fibers, and in particular relates to a batching system for producing carbon fiber polymer 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 process of carbon fiber polymer liquid, many raw materials need to be configured in advance, which requires the raw materials to be added to the batching tank for stirring. Since the raw materials are dry powder materials, during the addition process, the materials will be hung on the agitator of the batching tank or on the inner wall of the batching tank. Since the volume of the hanging materials cannot be predicted, the batching process cannot accurately control the batching accuracy, the batching time is long, and the values ​​do not meet the process requirements, which will directly cause the output polymer liquid to be unqualified, resulting in a series of problems such as waste of raw materials. In the prior art, after the raw materials are added, the agitator of the batching tank or the inner wall of the batching tank is flushed with a solvent to eliminate the hanging materials. However, it is necessary to use a water pipe to flush from the manhole after each batching is completed, which is time-consuming and labor-intensive, and the flushing process is prone to safety accidents such as poisoning.

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

DETAILED DESCRIPTION

[0045] 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.

[0046] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0047] 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.

[0048] like Figure 1-3 As shown, the utility model provides a batching system for producing carbon fiber polymer liquid, including a batching tank 1, and a spraying device 2 for spraying solvent is provided on the top of the batching tank 1; the spraying device 2 has a spiral nozzle 21 arranged in the batching tank 1, and the nozzle 21a of the spiral nozzle is set downward.

[0049] In the embodiment of the utility model, through the above-mentioned arrangement, a large-flow spiral nozzle 21 that can spray conical spray can be used to evenly spray the material in the batching tank 1, the agitator 4 in the batching tank 1 and the inner wall of the batching tank 1 when feeding, so that the input material can be completely dissolved in the solvent, and the agitator 4 and the inner wall of the batching tank 1 can be automatically flushed, thereby improving the production qualification rate and efficiency of the carbon fiber polymer liquid, reducing material waste and accidents, and saving human resources.

[0050] The batching tank 1 is used to carry and mix the raw materials required to produce carbon fiber polymer solution, which include solid materials and solvents. A spray device 2 is located on the top of the batching tank 1, facilitating the thorough mixing of the raw materials and solvent and facilitating the flushing of the agitator 4 and the inner wall of the batching tank 1. The spiral nozzle's nozzle 21a is positioned downward, ensuring that the solvent can directly act on the raw materials in the batching tank 1, improving the spraying and mixing effects. The spiral nozzle 21 provides a high-flow, conical mist spray, enabling wide-area spraying of the inner wall of the batching tank, the agitator 4, and the solid raw materials.

[0051] In addition, a heat coil is provided on the inner wall of the batching tank 1 for heating the interior of the batching tank 1 .

[0052] In the embodiment of the present invention, the spiral nozzle 21 includes a main body 211 and a flow guide portion 212;

[0053] A first flow channel is formed inside the main body 211, which gradually narrows from top to bottom. The outlet 211a at the bottom of the first flow channel is the nozzle 21a of the spiral nozzle.

[0054] A guide portion 212 extending spirally in the up-down direction is provided at the nozzle opening 21 a of the spiral nozzle, and a second flow channel 212 a gradually narrowing from top to bottom is formed inside the guide portion 212 .

[0055] In an embodiment of the present invention, the first flow channel gradually narrows from top to bottom. This design allows the solvent to be subjected to gradually increasing pressure when flowing through the first flow channel, thereby increasing the flow rate and impact force of the solvent.

[0056] The spiral design of the guide portion 212 not only further increases the flow rate and impact force of the solvent, but also enables the solvent to form a spiral spray trajectory when spraying, thereby more evenly covering the raw materials in the batching tank 1 and more evenly flushing the inner wall of the batching tank 1 and the agitator 4;

[0057] The synergistic effect of the main body 211 and the guide part 212 enables the solvent to pass through two stages of gradually narrowing flow channels and be sprayed out at a higher speed and more uniform distribution under the action of the spiral guide part 212, greatly improving the mixing effect of the solvent and the raw materials and greatly improving the flushing effect of the inner wall of the mixing tank 1 and the agitator 4. Figure 1 The multiple arrows in the figure show the spraying trajectory of the solvent of the spraying device 2.

[0058] The solvent enters the main body 211 of the spiral nozzle 21 from the spray device 2 at the top of the batching tank 1. It initially experiences a preliminary pressure increase and flow rate boost through the first flow channel. The solvent then enters the flow guide 212 and passes through the spirally extending second flow channel 212a, experiencing further pressure and flow rate boosts. Finally, the solvent is ejected from the nozzle in a spiral trajectory, evenly covering and acting on the interior of the batching tank 1.

[0059] In the embodiment of the present invention, the spraying device 2 includes a feed pipe 22;

[0060] The feed pipe 22 is inserted into the batching tank 1 from the top of the batching tank 1, and the feed port and the discharge port of the feed pipe 22 are respectively located outside and inside the batching tank 1;

[0061] The spiral nozzle 21 is installed at the discharge port of the feed pipe 22 .

[0062] In the embodiment of the present invention, the feed pipe 22 serves as a delivery channel for the solvent, and is responsible for introducing the solvent from the outside of the batching tank 1 to the inside for the spiral nozzle 21 to spray.

[0063] The solvent first enters the feed pipe 22 through the feed port of the feed pipe 22 outside the batching tank 1, then flows downward along the feed pipe 22 until it reaches the discharge port of the feed port inside the batching tank 1. At the discharge port of the feed port, the solvent is received by the spiral nozzle 21 and passes through the gradually narrowing first and second flow channels 212a in sequence. Finally, it is ejected from the nozzle 21a of the spiral nozzle at a higher speed and more evenly distributed, covering and acting on the inside of the batching tank 1.

[0064] Specifically, the feed pipe 22 includes a first vertical section 221, a horizontal section 222, and a second vertical section 223;

[0065] The first vertical section 221 is inserted into the batching tank 1 from the top thereof, and the feed port at the top and the discharge port at the bottom of the first vertical section 221 are located outside and inside the batching tank 1, respectively;

[0066] The horizontal section 222 extends from the discharge port of the first vertical section 221 to the middle of the mixing tank 1;

[0067] The second vertical section 223 extends downward from the discharge port at one end of the horizontal section 222 close to the middle of the batching tank 1;

[0068] The main body 211 of the spiral nozzle 21 is installed at the discharge port at the bottom end of the second vertical section 223 .

[0069] The first vertical section 221 serves as the initial passage for the solvent to enter the batching tank 1, guiding the solvent from the outside to the inside of the batching tank 1, preparing for the subsequent spraying process. The design of the horizontal section 222 allows the solvent to be horizontally distributed within the batching tank 1 before entering the second vertical section 223, facilitating the subsequent uniform spraying of the solvent. As the final passage for the solvent before entering the spiral nozzle 21, the second vertical section 223 is responsible for guiding the solvent from the horizontal section 222 to the spiral nozzle 21, providing the necessary pressure and flow rate for the spraying process.

[0070] The solvent first enters the first vertical section 221 through the feed port on the outside of the batching tank 1, then flows downward along the first vertical section 221 to the horizontal section 222. Within the horizontal section 222, the solvent undergoes a certain horizontal distribution, reaching the middle of the batching tank 1, before entering the second vertical section 223. Within the second vertical section 223, the solvent is further subjected to increased pressure and flow rate, ultimately reaching the main body 211 of the spiral nozzle 21. Inside the spiral nozzle 21, the solvent sequentially passes through the gradually narrowing first and second flow channels 212a, ultimately being ejected from the nozzle at a higher velocity and with a more uniform distribution.

[0071] An auxiliary feeding section coaxial with the feeding section of the first vertical section 221 is provided at the feeding port at the top end of the first vertical section 221 . The radial dimension of the auxiliary feeding section is larger than that of the first vertical section 221 , which can speed up the addition of the solvent.

[0072] In the embodiment of the present invention, a feeding port for feeding fixed raw materials is provided on the top of the batching tank 1 , and the feeding port 1 a of the batching tank is arranged lower than the spiral nozzle 21 .

[0073] In the embodiment of the present invention, the design of the feeding port enables the operator to conveniently feed fixed raw materials into the batching tank 1, and since the feeding port is lower than the spiral nozzle 21, it can ensure that the raw materials have fallen into the bottom or middle of the batching tank 1 before the solvent is sprayed, thereby avoiding the solvent from directly impacting the feeding port and reducing the splashing and waste of raw materials.

[0074] Furthermore, a feeding pipe 3 is provided on the top of the batching tank 1;

[0075] The feeding pipe 3 is inserted into the batching tank 1 and extends gradually from top to bottom toward the middle of the batching tank 1. The feeding port at the top and the discharge port at the bottom of the feeding pipe 3 are located outside and inside the batching tank 1 respectively.

[0076] The discharge port 31a of the feeding pipe serves as the feeding port 1a of the batching tank.

[0077] The top feed port of the feeding pipe 3 is located outside the batching tank 1, which is convenient for the operator to add raw materials; while the bottom discharge port is located inside the batching tank 1, and the discharge port 31a of the feeding pipe serves as the actual feeding port 1a of the batching tank.

[0078] The inclined configuration of feeding pipe 3 expedites the delivery of raw materials and allows them to gradually slide along the inclined pipe to the middle of batching tank 1, thus avoiding splashing and waste of raw materials during the delivery process. Furthermore, since the feeding port is located in the middle of batching tank 1, the raw materials can be more evenly distributed within batching tank 1, facilitating the subsequent mixing and dissolution process. Furthermore, since spiral nozzle 21 is located near the middle of batching tank 1, the raw materials can be brought close to the spiral nozzle's nozzle 21a, achieving sufficient mixing of the raw materials and solvent.

[0079] An auxiliary feeding section coaxial with the feeding port of the feeding pipe 3 is provided at the feeding port at the top end of the feeding pipe 3. The radial dimension of the auxiliary feeding section is larger than the radial dimension of the feeding pipe 3, which speeds up the feeding of solid raw materials.

[0080] In the embodiment of the present utility model, a stirrer 4 is provided on the top of the batching tank 1;

[0081] The stirring shaft 41 of the stirrer 4 is vertically inserted into the mixing tank 1;

[0082] The bottom end of the stirring shaft 41 is arranged below the feeding port 1a of the batching tank.

[0083] In the embodiment of the present invention, the stirrer 4 is used to stir the ingredients in the batching tank 1 to ensure that the ingredients in the tank can be evenly mixed.

[0084] The vertical stirring shaft 41 ensures that the stirrer 4 can reach the bottom of the batching tank 1, thereby achieving uniform stirring throughout the tank. The bottom end of the stirring shaft 41 is lower than the feeding port 1a of the batching tank, which means that when the ingredients are added from the feeding port, the stirring shaft 41 can contact and stir the ingredients.

[0085] In the embodiment of the present utility model, the agitator 4 and the spraying device 2 are arranged opposite to each other on the top of the batching tank 1;

[0086] The feeding pipe 3 is arranged close to the stirrer 4.

[0087] In the embodiment of the present invention, this means that the agitator 4 and the spray device 2 are mounted in opposing positions on top of the batching tank 1. This arrangement ensures that the agitator 4 stirs the ingredients while the spray device 2 evenly sprays the liquid into the raw materials. The purpose of this opposing arrangement is to achieve a synergistic effect between stirring and spraying, improving mixing efficiency and uniformity. The agitator 4 ensures that the ingredients are thoroughly mixed within the tank, while the spray device 2 ensures that the added liquid is evenly distributed throughout the ingredients.

[0088] The feeding pipe 3 is positioned near the agitator 4. This arrangement ensures that the added ingredients are quickly captured and stirred by the agitator 4, which helps reduce local accumulation of ingredients within the tank and improves mixing efficiency and uniformity. Agitating blades 42 are provided on the outer circumference of the agitator shaft 41.

[0089] Furthermore, the upper head 5 has a first side 51 and a second side of the upper head disposed lower than the top of the upper head 5 ;

[0090] The spray device 2 and the stirrer 4 are arranged on the first side 51 and the second side of the upper head relatively;

[0091] The feeding pipe 3 is provided on the first side 51 of the upper head.

[0092] The upper head 5 has two side surfaces, namely the first side 51 of the upper head and the second side 52 of the upper head. Both side surfaces are located below the top of the upper head 5. This design may be to leave enough space on the upper head 5 to install various equipment and pipelines while ensuring that they do not interfere with each other.

[0093] The spray device 2 and agitator 4 are positioned relative to each other on the first and second sides of the upper head, respectively. This means that there is a certain distance between them to ensure that they do not interfere with each other during operation. This layout helps achieve a synergistic effect between spraying and agitation, improving mixing efficiency and uniformity. The feeding pipe 3 is positioned on the first side 51 of the upper head so that the feeding pipe 3 is located close to the agitator 4.

[0094] Specifically, the spraying device 2 is located in the middle of the first side 51 of the upper head, and the stirring device is located in the middle of the second side 52 of the upper head.

[0095] Furthermore, a lower head 6 is provided at the bottom of the batching tank 1;

[0096] The nozzle 21a of the spiral nozzle is basically flush with the connection 53 between the material tank and the upper head, so that the position of the nozzle 21a of the spiral nozzle is relatively high, which can increase the area sprayed on the inner wall of the material tank 1 and the stirring shaft 41, and prevent the inner wall of the material tank 1 and the stirring shaft 41 from having areas that cannot be sprayed by the spiral nozzle 21.

[0097] The bottom end of the stirring shaft 41 is arranged above and close to the connection between the batching tank and the lower head 61, so that the stirring shaft 41 can fully stir the ingredients at the bottom of the batching tank 1 while avoiding collision or friction between the stirring shaft 41 and the lower head 6. In addition, setting the stirring shaft 41 slightly higher than the connection 61 between the batching tank and the lower head also helps to reduce potential damage to the lower head 6 during the stirring process.

[0098] 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.
