Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glue solution filtration, and more particularly, to a glue solution double filtration system for glass carbon fiber material production. BACKGROUND

[0002] In the production process of glass carbon fiber, the fiber needs to be treated with glue, and then the excess glue solution is removed through pultrusion. The resin glue solution fills the micro gaps between the fiber bundle and the fabric layer, which helps to stabilize the arrangement of the fiber and the shape of the preform. During the glue dipping process, due to the friction between the fiber and the yarn guide device, excessive fiber tension, insufficient glue penetration, etc., the fiber may break, resulting in hair and wool in the glue tank. When the glue solution circulates, the hair and wool will enter the pipeline and cause blockage.

[0003] In the prior art, a resin circulation filtration device is disclosed in Chinese Patent No. CN217745946U. The device includes a rack, a glue dipping frame with a glue dipping tank, a discharge hole in the bottom surface of the glue dipping frame, a transfer barrel with a transfer chamber below the discharge hole, a screen assembly in the transfer chamber, a glue outlet in the bottom surface of the transfer barrel, a glue pipe connected to the glue outlet, a diaphragm pump connected to the end of the glue pipe away from the transfer barrel, and a glue return pipe connected to the outlet of the diaphragm pump to return the resin to the glue dipping tank. The glue solution is transported to the transfer barrel through the pipe, and filtered by the screen assembly.

[0004] However, in actual use, the narrow pipe can easily cause blockage due to the adhesion of hair and wool to the surface of the pipe during glue return. The filter pressure of the screen is high when there is a large amount of hair and wool, and the screen needs to be replaced frequently, which affects production efficiency.

DETAILED DESCRIPTION

[0050] The application will be further described in detail below with reference to the accompanying drawings and examples, so that those skilled in the art can implement the application according to the description.

[0051] It should be understood that the terms such as "have", "contain" and "include" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0052] Example 1:

[0053] As shown in Figure 1 , Figure 2 , the application provides a glue solution double filtering system for glass fiber material production, which comprises:

[0054] A first filtering unit is arranged in the glue barrel 4, a circulating pipeline is arranged between the glue barrel 4 and the outer glue tank 2, and a diaphragm pump is arranged on the circulating pipeline.

[0055] A second filtering unit is arranged in the auxiliary tank 6 on one side of the outer glue tank 2, the auxiliary tank 6 is used to carry the glue solution overflowed from the outer glue tank 2 and returned during the fiber conveying process, and the auxiliary tank 6 is connected with the circulating pipeline.

[0056] The working principle and beneficial effects of the above technical solution are as follows:

[0057] This invention provides a dual filtration system for adhesive in the production of fiberglass carbon fiber materials. It is applied to an adhesive tank where the adhesive circulates. The adhesive tank has an adhesive return channel formed by a secondary tank 6 and other structures. A diaphragm pump drives the adhesive circulation. The system simultaneously includes a first filtration unit and a second filtration unit. The second filtration unit is located in the adhesive return channel, where it initially filters out feathers and lint during the adhesive flow. The first filtration unit is located inside the adhesive tank 4, filtering the adhesive entering the tank and further removing feathers and lint, thus improving the cleanliness of the returned adhesive and preventing clogging of the circulation pipeline. Compared to a system that only uses a filter screen on the adhesive tank 4, this reduces the filtration pressure of a single filter screen and eliminates the need for frequent filter screen replacements.

[0058] Example 2:

[0059] like Figure 1 As shown, based on the above embodiment 1, the outer glue tank 2 is detachably installed inside the glue impregnation tank body 1, and the middle of the outer glue tank 2 narrows inward; an overflow groove 3 is provided on one side of the outer glue tank 2; the maximum depth of the outer glue tank 2 is less than the maximum depth of the glue impregnation tank body 1.

[0060] The working principle and beneficial effects of the above technical solution are as follows:

[0061] An external glue tank 2 is added to the existing glue-dipping tank body 1. The glue-dipping tank body 1 is existing technology. The external glue tank 2 is set as a conical tank, and its two ends are installed on the glue-dipping tank body 1. The depth of the external glue tank 2 is less than the depth of the glue-dipping tank body 1. The middle of the external glue tank 2 is recessed to adapt to the yarn arrangement design of different products, thereby reducing the volume of the glue tank and improving the utilization rate of glue. The glue in the external glue tank 2 flows to the secondary tank 6 through the overflow tank 3, and then the glue is collected in the glue bucket 4. The glue is then returned to the external glue tank 2 by a diaphragm pump, so as to realize the continuous circulation of glue during the wetting process and ensure the stability of the glue quantity in the glue-dipping tank.

[0062] Example 3:

[0063] like Figure 1 As shown, based on the above embodiment 1, a return plate 5 is inclinedly provided on the yarn outlet side of the impregnation tank body 1, and the adhesive liquid in the return plate 5 flows back to the secondary tank 6.

[0064] The working principle and beneficial effects of the above technical solution are as follows:

[0065] After the fibers are impregnated, they need to be transported to a curing and molding equipment for curing. During the transport process, the adhesive on the fibers will drip off due to gravity. Therefore, a return plate 5 is installed between the yarn outlet side of the impregnation tank 1 and the curing and molding equipment. The dripping adhesive falls onto the return plate 5. Because the return plate 5 is inclined, the adhesive flows along the return plate 5 to the lower end and flows into the adhesive tank 4, realizing the recovery of the dripping adhesive during the transport process and further improving the utilization rate of the adhesive.

[0066] Example 4:

[0067] like Figure 1 As shown, based on the above embodiment 3, the impregnation tank body 1 is further provided with: a hidden trough 7 and a hidden trough overflow port 8. The hidden trough 7 is installed on the yarn outlet side of the impregnation tank body 1. The hidden trough 7 is inclined to guide the glue liquid to the hidden trough overflow port 8. The hidden trough overflow port 8 guides the glue liquid to the auxiliary trough 6.

[0068] The working principle and beneficial effects of the above technical solution are as follows:

[0069] The dark trough 7 is located on the yarn outlet side of the impregnation tank body 1. The adhesive liquid that flows back through the return plate 5 flows into the dark trough 7, and then enters the secondary trough 6 through the dark trough overflow port 8 at one end. All the returned adhesive liquid enters the adhesive bucket 4 through the secondary trough 6, realizing the recycling of adhesive liquid.

[0070] The overflow trough 3, return plate 5, secondary trough 6, dark trough 7, and dark trough overflow port 8 constitute a return assembly, and each structure is equipped with an inclined trough plate to form a plate-type return surface, replacing the separate return pipeline structure in the prior art. When the adhesive flows on the plate structure, it can be dispersed and spread out, so that some of the feathers in the adhesive can better adhere to the trough plate. The feathers are filtered out by the plate-type return surface itself, preventing the feathers from clogging the pipeline.

[0071] Example 5:

[0072] like Figure 1 As shown, based on the above embodiment 1, the first filter unit is configured as a first filter screen 15, which is detachably connected to the upper part of the glue tank 4.

[0073] The working principle and beneficial effects of the above technical solution are as follows:

[0074] The first filter unit is configured as a detachable first filter screen 15. The adhesive enters the adhesive tank 4 through the circulation pipeline and flows onto the first filter screen 15 to filter out the feathers and yarn mixed in the adhesive, ensuring the cleanliness of the circulating adhesive. After a period of use, the first filter screen 15 can be disassembled and replaced to prevent the first filter screen 15 from becoming clogged and affecting the flow rate of the adhesive return.

[0075] Example 6:

[0076] like Figure 1 As shown, based on the above embodiment 1, the second filter unit is configured as a second filter screen 16, which is detachably connected to the sub-slot 6 and located below the overflow port 8 of the dark slot.

[0077] The working principle and beneficial effects of the above technical solution are as follows:

[0078] A second filter screen 16 is arranged at one end of the auxiliary groove 6 to preliminarily filter the glue liquid flowing into the hidden groove 7, so that the hair and wool in the glue liquid are filtered out, the difficulty of manual cleaning is reduced, the filtering pressure of the first filter screen 15 is reduced, and the first filter screen 15 does not need to be frequently replaced.

[0079] Embodiment 7:

[0080] As shown in Figure 3 , based on the above-mentioned embodiment 1, the first filtering unit comprises:

[0081] A filtering ball cover 21 is rotationally arranged in the glue bucket 4, two filter hole areas 22 are symmetrically arranged on the filtering ball cover 21, and a plurality of filter holes are uniformly distributed in the filter hole areas 22.

[0082] A glue inlet pipe 23 is arranged at the top end of the filtering ball cover 21, the glue inlet pipe 23 is rotationally arranged on the cover plate of the glue bucket 4 and connected with the rotary driving mechanism, and the pipe opening of the glue inlet pipe 23 is communicated with the circulating pipeline.

[0083] A yarn discharge pipe 24 is connected to the bottom end of the filtering ball cover 21 and used for collecting the hair and wool filtered out from the filtering ball cover 21.

[0084] The working principle and beneficial effects of the above technical solution are as follows:

[0085] The first filtering unit is arranged in the form of the filtering ball cover 21, when the first filtering unit is used, the rotary driving mechanism is started to drive the glue inlet pipe 23 to rotate, and the glue inlet pipe 23 drives the filtering ball cover 21 to rotate; the glue liquid is injected into the glue inlet pipe 23 through the circulating pipeline and flows downward into the filtering ball cover 21, with the rotation of the filtering ball cover 21, the glue liquid flows outward under the action of centrifugal force, flows outward through the filter holes of the filter hole areas 22, the hair and wool are blocked in the filtering ball cover 21 and fall into the yarn discharge pipe 24 for collection. A cleaning port can be arranged at the bottom of the yarn discharge pipe 24. Through the above structural design, the filtering ball cover 21 is rotationally arranged, the glue liquid is input into the filtering ball cover 21 for centrifugal separation, the separated hair and wool are collected, the blockage of the filter holes is reduced, and then the flow rate of the glue liquid during the filtering and separating process is ensured, so that the glue liquid circulation process can be continuously and stably carried out.

[0086] Embodiment 8:

[0087] As shown in Figure 3 , Figure 4 , based on the above-mentioned embodiment 7, a defoaming sleeve 25 is connected to the bottom end of the filtering ball cover 21, the defoaming sleeve 25 is sleeved outside the yarn discharge pipe 24, the bottom end of the defoaming sleeve 25 is rotationally connected with the bottom of the glue bucket 4, and the outer wall of the defoaming sleeve 25 is provided with a defoaming convex structure.

[0088] The working principle and beneficial effects of the above technical solution are as follows:

[0089] When the dual filtration system is in use, the filter ball cover 21 and the second filter screen 16 filter the wool yarn and filter out some of the air bubbles generated during the impregnation process. However, some air bubbles still flow back into the glue tank 4. The circulation pipeline provides the glue liquid return power through a diaphragm pump. The diaphragm pump adjusts the output flow rate and pressure through corresponding pressure feedback. When there are too many air bubbles in the glue liquid, it will lead to inaccurate glue liquid pressure control. Therefore, a defoaming sleeve 25 is set at the bottom of the filter ball cover 21. On the one hand, the defoaming sleeve 25 can provide support for the filter ball cover 21. On the other hand, the defoaming sleeve 25 generates eddies as the filter ball cover 21 rotates, increasing the flow velocity near the defoaming sleeve 25 and forming a low-pressure zone. This draws the air bubbles toward the defoaming sleeve 25, where they come into contact with the defoaming protrusions, breaking up and venting large air bubbles, reducing the air bubble content in the returned glue liquid, and improving the accuracy of pressure control.

[0090] Example 9:

[0091] like Figure 5 As shown, based on the above embodiment 8, the defoaming protrusion structure includes multiple pyramidal protrusions 26. The pyramidal protrusions 26 are configured as pyramidal structures with the tips of the pyramids facing the outside of the defoaming sleeve 25. The structural dimensions of the multiple pyramidal protrusions 26 are different and they are irregularly arranged on the outer wall of the defoaming sleeve 25.

[0092] The working principle and beneficial effects of the above technical solution are as follows:

[0093] The defoaming protrusion structure is configured as multiple pyramidal protrusions 26. The pyramidal protrusions 26 can be configured as triangular or quadrangular pyramids with sharp pyramidal tips. When bubbles gather at the defoaming sleeve 25, large bubbles come into contact with the pyramidal tips and burst them. Due to the irregular arrangement of the multiple pyramidal protrusions 26, when the adhesive rotates at the defoaming sleeve 25, it can flow along the channels between the pyramidal protrusions 26, frequently changing the flow direction of the adhesive near the defoaming sleeve 25, causing the bubbles to move up and down, making more sufficient contact with the pyramidal tips, and promoting the dispersion of large bubbles into small bubbles or microbubbles, thereby reducing the bubble content in the adhesive.

[0094] Example 10:

[0095] like Figure 6 As shown, based on the above embodiment 8, the defoaming protrusion structure includes multiple sets of defoaming guide strips arranged radially along the defoaming sleeve 25; each set of defoaming guide strips is provided with two first guide strips 27 and two second guide strips 28. The first guide strip 27 is configured as a V-shaped bending structure, with the upper and lower first guide strips 27 arranged symmetrically and the bending points close to each other; the second guide strip 28 is inclined, with the upper and lower second guide strips 28 arranged symmetrically, and the ends close to the first guide strip 27 are far apart.

[0096] The working principle and beneficial effects of the above technical solutions are:

[0097] The defoaming convex structure is arranged as multiple groups of defoaming flow guide strips, two first flow guide strips 27 and two second flow guide strips 28 in each group form staggered flow paths on the side wall of the defoaming sleeve 25, when the glue solution rotates at the defoaming sleeve 25, part of the glue solution flows along the inner wall of the defoaming sleeve 25, and part of the glue solution moves upward or downward under the action of the flow guide strips, the flow direction of the glue solution near the defoaming sleeve 25 is frequently changed, the bubbles move upward and downward, and the bubbles are broken under the extrusion of the edges of the flow guide strips when moving, which promotes large bubbles to disperse into small bubbles or micro-bubbles and reduces the bubble content in the glue solution.

[0098] Embodiment 11:

[0099] As shown in the above embodiment 7, the rotary drive mechanism comprises: Figure 3

[0100] The first drive motor 31 is installed on the motor support 32 at the top end of the glue bucket 4;

[0102] The second pulley 34 is installed on the glue inlet pipe 23, and the second pulley 34 is connected with the first pulley 33 through the synchronous belt 30.

[0103] The working principle and beneficial effects of the above technical solutions are:

[0104] When the rotary drive mechanism is used, the first drive motor 31 is started to drive the first pulley 33 to rotate, the first pulley 33 drives the second pulley 34 to rotate through the synchronous belt 30, the second pulley 34 is integrally arranged on the glue inlet pipe 23, and then the glue inlet pipe 23 is driven to rotate, thereby realizing the rotary drive of the filter ball cover 21.

[0105] Embodiment 12:

[0106] As shown in the above embodiment 11, a partitioned filtering assembly is arranged in the filter ball cover 21, and the partitioned filtering assembly comprises: Figures 7-9

[0107] The drive shaft 35 is rotationally arranged at the center of the filter ball cover 21 and horizontally arranged;

[0108] The second drive motor 36 is installed on the filter ball cover 21, and the output end of the second drive motor 36 is connected with the drive shaft 35;

[0109] The four rotating sleeves 37 are rotationally arranged on the drive shaft 35, and the multiple rotating sleeves 37 are arranged at intervals.​​

[0110] The partition baffle 38 is connected with the four rotating sleeves 37 respectively, and the four partition baffles 38 are arranged uniformly along the circumferential direction of the rotating sleeve 37, and the outer edge of the partition baffle 38 is in contact with the inner wall of the filter ball cover 21; in the initial position, the partition baffle 38 is at a preset angle relative to the vertical axis of the filter ball cover 21, and the four partition baffles 38 divide the inside of the filter ball cover 21 into a first filtering area 41, a second filtering area 42, a yarn discharging area 43 and a buffer area 44, which are arranged in sequence along the rotating direction of the driving shaft 35; the first filtering area 41 is communicated with the glue inlet pipe 23, and the yarn discharging area 43 is communicated with the yarn discharging pipe 24.

[0111] The partition filtering assembly further comprises:

[0112] The three dial piece groups are connected to the driving shaft 35, and the dial piece groups are arranged at intervals between the rotating sleeves 37, each dial piece group comprising four dial pieces 45, and the four dial pieces 45 being arranged uniformly along the circumferential direction of the driving shaft 35;

[0113] The lock ring assembly is provided with a first lock ring 46 on both sides of the dial piece 45, and a second lock ring 47 is correspondingly provided on both sides of the partition baffle 38, and a spring is connected between the first lock ring 46 and the second lock ring 47;

[0114] The limiting groove 48 is provided on one side of the filter ball cover 21 and is in the same direction as the rotating direction of the driving shaft 35;

[0115] The limiting block 49 is slidingly connected in the limiting groove 48, and a spring is connected between the limiting block 49 and the groove bottom of the limiting groove 48, and the limiting block 49 blocks the partition baffle 38 provided on the side surface.

[0116] The working principle and beneficial effects of the above technical solution are:

[0117] In the initial state, the spring is connected with the first lock ring 46 and the second lock ring 47, so that the partition baffle 38 is located between the two adjacent dial pieces 45 in the same group; the limiting block 49 is extended under the action of the spring, and the partition baffle 38 on one side of the first filtering area 41 is limited, and the partition baffle 38 on the other side is higher than the horizontal plane of the center of the filter ball cover 21. When the glue is fed through the glue inlet pipe 23, the glue liquid falls into the first filtering area 41, and flows to one side of the filter hole area 22 under the action of centrifugal force as the filter ball cover 21 rotates, and the glue liquid flows out after being filtered through the filter hole, and the hair and yarn are intercepted. As the amount of glue liquid increases, the partition baffle 38 on one side is kept stationary by limiting, and the partition baffle 38 on the other side is pressed to rotate downward, and the rotation angle is limited by the limiting block 49; at the same time, as the amount of glue liquid increases, the weight in the first filtering area 41 increases, and the centrifugal force generated when the filter ball cover 21 rotates is also larger, and the filtering effect is better.

[0118] After the first preset time, the second driving motor 36 is started to drive the rotation of the driving shaft 35, the driving shaft 35 drives the rotation of the rotating sleeve 37 and the partition baffle 38 through the tab 45, the rotation angle is 90 degrees, the partition baffle 38 extrudes the limiting block 49 to shrink into the limiting groove 48, and the partition baffle 38 is popped out when it passes. In this way, the glue solution in the first filtering area 41 is moved to the position of the second filtering area 42; with the rotation of the filtering ball cover 21, the remaining glue solution in the second filtering area 42 flows out through the filter hole area 22 on the other side, so that the glue solution is fully filtered. After the second preset time, the second driving motor 36 is started again to drive the rotation of the driving shaft 35 by 90 degrees, the hair and feather yarn filtered out of the glue solution is moved to the yarn discharge area 43, the hair and feather yarn falls into the yarn discharge pipe 24 along the inner wall of the filtering ball cover 21, and the collection of the hair and feather yarn is realized. After the third preset time, the second driving motor 36 is started again to drive the rotation of the driving shaft 35 by 90 degrees to the buffer area 44, and sufficient space is reserved for the downward rotation of the partition baffle 38.

[0119] Through the above structural design, with the rotation of the filtering ball cover 21 and the use of the second driving motor 36, the first filtering, the second filtering and the yarn discharge operation of the glue solution are realized, the whole operation process is continuously carried out, the full separation of the glue solution and the hair and feather yarn is realized, and the waste of the glue solution during the yarn discharge is reduced. At the same time, the first filtering area 41, the second filtering area 42, the yarn discharge area 43 and the buffer area 44 are sequentially arranged along the rotation direction of the driving shaft 35, when the amount of glue changes, the centrifugal force of each area will change accordingly, most of the weight of the glue solution is concentrated in the first filtering area 41, and a small part is concentrated in the second filtering area 42, so that the centrifugal separation effect of the glue solution is improved.
