Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The technical solutions of the present application are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 3, the apparatus 100 for preparing a highly uniform carbon fiber slurry according to an embodiment of the present invention includes a stirring vessel 1, a first stirring shaft 2, and a first driving member (not shown). The stirring barrel 1 is provided with a feed inlet (not shown in the figure) and a discharge outlet 101, a plurality of hemispherical protrusions 102 and a plurality of strip-shaped protrusions 103 are arranged on the inner side wall of the stirring barrel 1, the hemispherical protrusions 102 and the strip-shaped protrusions 103 are arranged at intervals in the axial direction of the stirring barrel 1, and the strip-shaped protrusions 103 extend spirally along the axial direction of the stirring barrel 1.
The first stirring shaft 2 is rotatably arranged on the stirring barrel 1, and one end of the first stirring shaft 2 is provided with a first stirring blade 3 and stretches into the stirring barrel 1. The first driving piece is arranged on the stirring barrel 1 and is in transmission connection with the first stirring shaft 2 so as to drive the first stirring shaft 2 to rotate. The first driving piece can be a driving motor, the driving motor is in transmission connection with the first stirring shaft 2 through a coupler or a gear pair, and the rotation of the first stirring shaft 2 is controlled by controlling the starting and stopping of the driving motor.
In the use process of the preparation device 100 of the high-uniformity carbon fiber slurry, carbon fibers and dispersion liquid are placed into the stirring barrel 1 through the feed inlet, then the first driving piece is controlled to drive the first stirring shaft 2 to rotate, the first stirring shaft 2 rotates to drive the first stirring blade 3 to rotate, and the first stirring blade 3 drives the mixture of the carbon fibers and the dispersion liquid to be mixed and stirred in the stirring barrel 1.
Because the hemispherical bulges 102 and the strip-shaped bulges 103 on the inner wall of the stirring barrel 1 are arranged at intervals in the axial direction of the stirring barrel 1, the hemispherical bulges 102 and the strip-shaped bulges 103 can enable the dispersion liquid to form a plurality of high-strength micro-turbulences so as to enhance the flow of the dispersion liquid in the stirring barrel 1, destroy grids among carbon fibers, reduce flocculation of the carbon fibers, improve the capability of dispersing the carbon fibers, enable the carbon fibers to be dispersed in the dispersion liquid more uniformly, and improve the uniformity of preparing the carbon fiber slurry. After the stirring is carried out for a certain time, taking out the stirred carbon fiber slurry from the stirring barrel 1, observing the dispersion condition of the carbon fibers in the dispersion liquid, and obtaining the high-uniformity carbon fiber slurry without finding carbon fiber flocks and completely dispersing the carbon fibers. The high-uniformity carbon fiber slurry sequentially passes through a forming process, a sizing process and a drying process to form the high-uniformity carbon fiber felt.
Accordingly, the carbon fiber slurry prepared by the preparation apparatus 100 according to the embodiment of the present invention has advantages of high uniformity and the like, so as to prepare a high-uniformity carbon fiber mat.
Specifically, during the stirring process of the first stirring shaft 2, the rotation direction of the first stirring shaft 2 is opposite to the spiral extending direction of the strip-shaped protrusions 103, so that the strip-shaped protrusions 103 can generate downward acting force on the dispersion liquid to enhance the turbulence effect of the dispersion liquid.
In some embodiments, as shown in fig. 3, the apparatus 100 for preparing a high-uniformity carbon fiber slurry according to an embodiment of the present invention further includes a buffer tub 4, a second stirring shaft 5, a second driving member, and a vacuum pump 7. The buffer tub 4 has a pulp inlet 401, a pulp outlet 402, an air inlet 403, and an air suction port 404, and the pulp inlet 401 communicates with the discharge port 101. The second stirring shaft 5 is rotatably arranged on the buffer barrel 4, and one end of the second stirring shaft 5 is provided with a second stirring blade 6 and extends into the buffer barrel 4.
The second driving piece is arranged on the buffer barrel 4 and is in transmission connection with the second stirring shaft 5 so as to drive the second stirring shaft 5 to rotate. The vacuum pump 7 communicates with the pumping port 404 to pump vacuum in the buffer tub 4. The second driving piece can be a driving motor, the driving motor is in transmission connection with the second stirring shaft 5 through a coupler or a gear pair, and the rotation of the second stirring shaft 5 is controlled by controlling the starting and stopping of the driving motor.
In the use process of the device 100 for preparing the high-uniformity carbon fiber slurry, the high-uniformity carbon fiber slurry after being stirred in the stirring barrel 1 is conveyed into the buffer barrel 4 through the conveying pipeline, then the second driving piece is controlled to drive the second stirring shaft 5 to rotate, the second stirring shaft 5 rotates to drive the second stirring blade 6 to rotate, the second stirring blade 6 drives the carbon fiber slurry to be stirred, and the vacuum pump 7 is started to vacuumize the buffer barrel 4. When the vacuum pump 7 is turned on, the gas in the buffer tank 4 is pumped out, and the gas is supplied into the buffer tank 4 through the gas inlet 403 due to the pressure difference, so as to prevent the subsequent transportation process of the slurry from being affected by too high vacuum in the buffer tank 4.
Because a large number of bubbles can be generated in the stirring process of the dispersion liquid, the surface of the carbon fiber can be affected by the adsorption of the bubbles on the surface of the carbon fiber, so that when the carbon fiber slurry is conveyed to the buffer barrel 4, the stirring and vacuumizing can accelerate the breakage of the bubbles in the dispersion liquid, and the planeness of the carbon fiber felt formed later is improved.
Optionally, as shown in fig. 3, the through-flow cross-sectional area of the air inlet 403 is smaller than the through-flow cross-sectional area of the air extraction opening 404, so as to ensure that the air input of the buffer barrel 4 is smaller than the air extraction amount of the vacuum pump 7, prevent the buffer barrel 4 from forming excessive negative pressure, and cause the buffer barrel 4 to deform, thereby being beneficial to improving the working reliability of the working buffer barrel 4.
In some embodiments, the plurality of hemispherical protrusions 102 are divided into a plurality of protrusion groups including a plurality of hemispherical protrusions 102 arranged at intervals along the extending direction of the bar-shaped protrusions 103, and the plurality of protrusion groups and the plurality of bar-shaped protrusions 103 are alternately arranged in order in the axial direction of the stirring vessel 1.
For example, as shown in fig. 2, the bar-shaped protrusions 103 have one protrusion group on both sides in the up-down direction, and each protrusion group includes three hemispherical protrusions 102 arranged at intervals along the extending direction of the bar-shaped protrusions 103. After the turbulence is generated on the two sides of the strip-shaped protrusions 103, the turbulence is generated again at the positions of the hemispherical protrusions 102, so that the dispersion can be always in a turbulence state in the stirring process, and the uniformity of the prepared carbon fiber slurry is further improved.
In some embodiments, the protruding height of the bar-shaped protrusion 103 is 1cm-10cm. Preferably, the protruding height of the bar-shaped protrusion 103 is 5cm. When the projection height of the bar-shaped projection 103 is set too small, the intensity of turbulence occurring at the position of the bar-shaped projection 103 is small, resulting in poor stirring effect; when the projection height of the bar-shaped projections 103 is set too large, the dispersion is caused to be layered on the upper and lower sides of the bar-shaped projections 103, resulting in poor stirring effect.
Alternatively, as shown in FIG. 2, two adjacent strip-shaped protrusions 103 are spaced apart by a distance H, wherein 5 cm.ltoreq.H.ltoreq.30 cm. Preferably, the distance H between two adjacent strip-shaped protrusions 103 is 15cm. When the spacing distance between the adjacent two strip-shaped protrusions 103 is set too small, turbulence generated by the dispersion liquid is liable to interfere with each other, resulting in poor stirring effect. When the spacing distance between two adjacent strip-shaped protrusions 103 is too large, the dispersion liquid between the two adjacent strip-shaped protrusions 103 cannot generate turbulence, and the stirring effect is not improved.
Alternatively, as shown in FIG. 2, the hemispherical protrusion 102 has a diameter D, where 1/5 H.ltoreq.D.ltoreq.1/2H. For example, if the distance H between two adjacent strip-shaped protrusions 103 is 15cm, the diameter of the hemispherical protrusion 102 may be 3cm, 5cm or 7.5cm, so that the turbulence interference phenomenon caused by too small distance between the hemispherical protrusion 102 and the strip-shaped protrusion 103 due to too large diameter of the hemispherical protrusion 102 is avoided. The problem that the space between the hemispherical protrusions 102 and the strip-shaped protrusions 103 is large due to the fact that the diameter of the hemispherical protrusions 102 is too small is avoided, micro-turbulence cannot be formed in the dispersion liquid between the hemispherical protrusions 102 and the strip-shaped protrusions 103, and the stirring effect is reduced.
In some embodiments, as shown in fig. 2, the smooth transition between the two ends of the bar-shaped protrusion 103 and the inner side wall of the stirring barrel 1 aims to reduce the risk that the carbon fibers are cut off by the bar-shaped protrusion 103 in the stirring process, which is beneficial to improving the integrity of the carbon fibers.
The application method of the preparation device 100 of the high-uniformity carbon fiber slurry in the embodiment of the invention comprises the following steps:
placing the carbon fiber and the dispersion liquid into a stirring barrel 1, and stirring by using a first stirring shaft 2, wherein the stirring direction of the first stirring shaft 2 is opposite to the spiral direction of the strip-shaped protrusions 103, so as to prepare high-uniformity carbon fiber slurry;
and conveying the prepared high-uniformity carbon fiber slurry into a buffer barrel 4, stirring the carbon fiber slurry by using a second stirring shaft 5, and starting a vacuum pump 7 to vacuumize the buffer barrel 4.
Accordingly, the method of using the manufacturing apparatus 100 of the embodiment of the present invention can manufacture highly uniform carbon fiber slurry to manufacture highly uniform carbon fiber mat.
Optionally, carrying out dehydration molding process on the high-uniformity carbon fiber slurry, carrying out sizing process on the carbon fiber after the molding process, carrying out sizing on the carbon felt by adopting a spray coating or gumming mode on the adhesive glue, carrying out drying process on the carbon fiber after the sizing process, transferring the sized carbon felt to a drying oven, setting the temperature of the drying oven to 120 ℃, and drying for 10min, and obtaining the finished carbon felt after the drying is finished to form the high-uniformity carbon fiber felt.
Alternatively, the length of the carbon fibers put into the stirring tank 1 is 6mm to 12mm. Preferably, the length of the carbon fiber put into the stirring tank 1 is 9mm, and since the preparation apparatus 100 according to the embodiment of the present invention can improve the dispersion ability of the carbon fiber in the dispersion liquid, the length of the carbon fiber can be appropriately set longer to facilitate the processing and production of the carbon fiber.
