Description

Technical Field

[0001] The present application relates to the technical field of carbon fiber processing, and in particular to a carbon fiber surface treatment water washing device. Background Art

[0002] In the production process of carbon fiber materials, the surface of the carbon fiber tow needs to be treated and washed. There are problems such as incomplete electrolyte cleaning and electrolyte adhesion on the carbon fiber tow. At the same time, there are also carbon fiber breakages, which accumulate and settle in the washing tank, especially near the guide rollers, which affects the production efficiency and product quality and is not convenient for cleaning. Utility Model Content

[0003] The purpose of the present application is to provide a carbon fiber surface treatment water washing device to solve the problem that during the prior art carbon fiber water washing process, broken fibers and other debris are precipitated and accumulated in the water washing tank, making it difficult to clean.

[0004] An embodiment of the present application provides a carbon fiber surface treatment water washing device, comprising: a water washing tank for accommodating a treatment liquid, a first guide roller being arranged in the water washing tank so that the carbon fiber conducted by the first guide roller is at least partially immersed in the treatment liquid and moves along a first direction, the water washing tank having a liquid inlet facing along a second direction so that the treatment liquid in the water washing tank can flow along the second direction, so that the treatment liquid contacts the carbon fiber along the second direction and guides the debris precipitated in the water washing tank to one side of the water washing tank; wherein the first direction intersects with the second direction.

[0005] By providing a liquid inlet on the side wall of the water washing tank, a treatment liquid or other liquid can be injected through the liquid inlet, so that the debris precipitated in the water washing tank can be moved to one side of the water washing tank, which is convenient for cleaning the debris, such as the debris cleaned on the surface of the carbon fiber and the broken carbon fiber; at the same time, the treatment liquid in the water washing tank can move laterally (intersecting with the moving direction of the carbon fiber), thereby improving the cleaning effect on the surface of the carbon fiber.

[0006] In a possible implementation manner, the first direction is perpendicular to the second direction.

[0007] By making the liquid inlet perpendicular to the direction of the carbon fibers, the distance between the liquid inlet and the carbon fibers is minimized, thereby reducing the kinetic energy loss of the liquid entering from the liquid inlet.

[0008] In one possible implementation, a plurality of partitions are arranged in a first direction in the water washing tank to divide the water washing tank into a plurality of water washing zones, each water washing zone is provided with a liquid inlet, and a first guide roller is provided in each water washing zone.

[0009] By setting partitions, the washing tank is divided into smaller washing areas. The liquid inlet is set corresponding to the number of washing areas to make the flow rate of the fluid along the second direction faster and to facilitate the distribution of debris in different washing areas for cleaning.

[0010] In a possible implementation manner, a second guide roller for conducting carbon fibers is arranged above each separator.

[0011] By setting the second guide roller, the carbon fiber is sequentially wound on the first guide roller and the second guide roller, which increases the moving distance of the carbon fiber in the washing tank. When the length of the washing tank is constant, the processing effect on the carbon fiber is improved.

[0012] In a possible implementation, all the partitions are parallel to each other, so as to facilitate the positioning and installation of the partitions.

[0013] In a possible implementation, the water washing tank has a water inlet and a water outlet distributed at two ends of the water washing tank along a first direction, so as to allow the treatment liquid in the water washing tank to flow along the first direction.

[0014] By providing a water inlet and a water outlet, the processing liquid in the washing tank can flow along the first direction, thereby improving the processing efficiency of the carbon fiber.

[0015] In a possible implementation, the water washing tank is provided with a fiber inlet and a fiber outlet along the first direction, a water inlet is provided at the fiber outlet, and a water outlet is provided at the fiber inlet.

[0016] By making the moving direction of the carbon fibers opposite to the flow direction of the treatment liquid, the surface treatment efficiency of the carbon fibers is further improved.

[0017] In a possible implementation, the height of the partition gradually decreases along the direction from the water inlet to the water outlet.

[0018] By distributing the height of the partition in a stepped manner, when the treatment liquid in the washing tank flows along the first direction, the treatment liquid in the previous washing zone can overflow from the upper end of the partition to the next washing zone in sequence, and the debris can be precipitated in different washing zones respectively, so that the fluid enters each washing zone through the liquid inlet and pushes the precipitated debris to move to one side of the washing tank.

[0019] In one possible implementation, an exchange tank is disposed outside the water washing tank, and a water inlet and a water outlet are connected to the exchange tank through a pipeline, and a circulation pump is provided on the pipeline.

[0020] By setting up an exchange tank, the treatment liquid in the washing tank can always be in a flowing state, thereby improving the surface treatment efficiency of the carbon fiber, recycling the treatment liquid, and saving resources.

[0021] In one possible implementation, the upper end of the washing tank is an open structure.

[0022] By setting the upper end of the washing tank as an open structure, it is convenient to operate the carbon fiber, so that the carbon fiber can be wound on the first guide roller and the second guide roller in sequence.

[0023] The above description is only an overview of the technical solution of the present application.

[0035] Example

[0036] Please refer to Figure 1-Figure 3 ,in Figure 1 It is a schematic diagram of the three-dimensional structure of the water washing tank according to an embodiment of the present application; Figure 2 for Figure 1 A side perspective structural diagram of Figure 3 This is a schematic diagram of the structure of installing the first guide roller and the second guide roller in the washing tank of an embodiment of the present application.

[0037] The embodiment of the present application provides a carbon fiber surface treatment water washing device, including a water washing tank 10, the water washing tank 10 is used to accommodate a treatment liquid, a first guide roller 40 is arranged in the water washing tank 10, so that the carbon fiber 60 conducted by the first guide roller 40 is at least partially immersed in the treatment liquid and moves along a first direction X, the water washing tank 10 has a liquid inlet 20 oriented along a second direction Y, so that the treatment liquid in the water washing tank 10 can flow along the second direction Y, so that the treatment liquid contacts the carbon fiber 60 along the second direction Y and guides the sundries precipitated in the water washing tank 10 to one side of the water washing tank 10; wherein the first direction X intersects with the second direction Y.

[0038] By providing a liquid inlet 20 on the side wall of the water washing tank 10, a treatment liquid or other liquid can be injected through the liquid inlet 20, so that the debris precipitated in the water washing tank 10 can be moved to one side of the water washing tank 10, which is convenient for cleaning the debris, such as the debris cleaned on the surface of the carbon fiber 60 and the broken fibers of the carbon fiber 60; at the same time, the treatment liquid in the water washing tank 10 can move laterally (intersecting with the moving direction of the carbon fiber 60), thereby improving the cleaning effect on the surface of the carbon fiber 60.

[0039] Specifically, the carbon fiber 60 is a carbon fiber tow treatment liquid, which is a solution used to treat the surface of the carbon fiber 60. The purpose of washing the carbon fiber 60 is to fully wash away the electrolyte on the surface of the carbon fiber tow by the treatment liquid. The first guide roller 40 is provided with a rotating shaft, and both ends of the rotating shaft are rotatably connected to both sides of the inner wall of the washing tank 10.

[0040] The liquid inlet 20 is provided on the side wall of the water washing tank 10, and the liquid inlet 20 can be connected to a liquid inlet pipe to continuously inject additional treatment liquid into the water washing tank 10, so that the treatment liquid in the water washing tank 10 moves along the second direction Y, and the treatment liquid can impact the carbon fiber 60 along the second direction Y, thereby improving the surface treatment efficiency of the carbon fiber 60. When there are multiple liquid inlets 20, all the liquid inlets 20 can be located on the same side of the water washing tank 10, and after the treatment is injected through the liquid inlet 20, the sundries settled in the water washing tank 10 are located on the same side of the water washing tank 10, so that the cleaning personnel can centrally treat the sundries.

[0041] The carbon fiber 60 is an inorganic fiber with a carbon main chain structure having a carbon content of more than 90% formed by the cracking and carbonization of organic fibers such as polyacrylonitrile, asphalt or viscose under high temperature. The carbon fiber 60 mentioned in some embodiments generally refers to carbon fiber filaments.

[0042] As a high-performance material, carbon fiber has unique physical and chemical properties. In the production and application of carbon fiber, a water washing process is usually required.

[0043] When washing carbon fiber filaments, you usually need to pay attention to the following points: Pretreatment: Before washing, make sure that the carbon fiber filaments are not attached with too much oil, impurities or chemicals, which may affect its performance. Water temperature control: The water temperature used should be moderate, avoid being too high or too low to prevent damage to the carbon fiber filaments.

[0044] When the surface of the carbon fiber 60 is treated with the treatment liquid, the debris that falls off the surface of the carbon fiber 60 and the broken fibers of the carbon fiber 60 settle and gather in the water washing tank 10. At this time, the treatment liquid flowing along the second direction Y can push the settled debris to the other side of the water washing tank 10, so that the operator can pick up the debris on one side of the water washing tank 10 without manually picking up the debris located in the middle of the water washing tank 10. There is no need to stop the machine for operation, and the debris in the water washing tank 10 can be picked up online, thereby improving the cleaning efficiency.

[0045] In a possible implementation, the first direction X is perpendicular to the second direction Y. By making the liquid inlet 20 perpendicular to the carbon fiber 60 , the distance between the liquid inlet 20 and the carbon fiber 60 is minimized, thereby reducing the kinetic energy loss of the liquid entering from the liquid inlet 20 .

[0046] In one possible implementation, a plurality of partitions 30 are arranged in the washing tank 10 along the first direction X to divide the washing tank 10 into a plurality of washing zones 31 , each washing zone 31 is provided with a liquid inlet 20 , and a first guide roller 40 is provided in each washing zone 31 .

[0047] By setting the partition 30, the washing tank 10 is divided into smaller washing areas 31, and the liquid inlet 20 is set corresponding to the number of the washing areas 31 to make the flow rate of the fluid along the second direction Y faster, and also to facilitate the distribution of debris in different washing areas 31 for cleaning.

[0048] In this embodiment, the washing tank 10 is divided into three washing zones 31 by setting two partitions 30. It is understandable that in order to extend the travel of the carbon fiber tow in the washing tank 10 to achieve a better washing effect, the number of washing zones 31 in each washing tank 10 can be increased according to actual needs, and no further details are given for this.

[0049] Specifically, the lower end and left and right ends of the partition 30 can be welded or bonded to the inner wall of the washing tank 10, or a slot can be set on the inner walls and bottom walls on both sides opposite to each other inside the washing tank 10, and the partition 30 is installed in the slot from top to bottom, and the thickness of the partition 30 is matched with the width of the slot.

[0050] When the partition 30 is connected to the washing tank 10 by means of a card slot, it is convenient to quickly install the partition 30 into the washing tank 10, and it is convenient for the user to set the number of partitions 30 and the distance between adjacent partitions 30 according to their own needs, thereby changing the space size of the washing area 31.

[0051] The partition 30 can be made of steel with a certain dead weight to ensure that when the partition 30 is placed in the washing tank 10 by means of a slot fit, the partition 30 will not automatically move upward under the buoyancy of water.

[0052] Adjacent washing areas 31 are independent of each other. In the washing area 31 where broken carbon fiber 60 and other debris are concentrated, the frequency of injecting treatment liquid from the liquid inlet 20 can be increased to push the debris to one side of the washing tank in time and to remove the debris in time to avoid the accumulation of debris in the washing area and affect the normal washing of the carbon fiber 60.

[0053] In a possible implementation manner, a second guide roller 50 for conducting the carbon fibers 60 is disposed above each separator 30 .

[0054] By providing the second guide roller 50, the carbon fiber 60 is sequentially wound on the first guide roller 40 and the second guide roller 50, thereby increasing the moving distance of the carbon fiber 60 in the washing tank 10. When the length of the washing tank 10 is constant, the processing effect on the carbon fiber 60 is improved.

[0055] For details, please refer to Figure 2 The arrow symbol on the carbon fiber 60 in the figure indicates its moving direction. A winding structure is provided at the right end of the washing tank 10. The winding structure is connected to the carbon fiber 60 to enable the carbon fiber 60 to move along the first direction X.

[0056] The second guide roller 50 is arranged above the treatment liquid, and the first guide roller 40 is completely immersed in the treatment liquid. The first guide roller 40 and the second guide roller 50 guide the carbon fiber 60, and also enable the carbon fiber 60 to always be in a straight state, so that the carbon fiber 60 can move smoothly in the first direction X.

[0057] In a possible implementation, all the partitions 30 are parallel to each other, so as to facilitate the positioning and installation of the partitions 30 .

[0058] Specifically, all the partitions 30 are vertically installed inside the washing tank 10 .

[0059] In a possible implementation, the water washing tank 10 has a water inlet 11 and a water outlet 12 distributed along a first direction X at both ends of the water washing tank 10 , so as to allow the treatment liquid in the water washing tank 10 to flow along the first direction X.

[0060] By providing the water inlet 11 and the water outlet 12 , the treatment liquid in the washing tank 10 can flow along the first direction X, thereby improving the treatment efficiency of the carbon fibers 60 .

[0061] Specifically, a water inlet pipe can be provided at the water inlet 11, a water outlet pipe can be provided at the water outlet 12, and valves can be provided on both the water inlet pipe and the water outlet pipe to control the opening and closing of the water inlet 11 and the water outlet 12 according to usage requirements.

[0062] The valve can be a solenoid valve or a manual switch valve.

[0063] In a possible implementation, along the first direction X, the washing tank 10 is provided with a fiber inlet 70 and a fiber outlet 80 , the fiber outlet 80 is provided with a water inlet 11 , and the fiber inlet 70 is provided with a water outlet 12 .

[0064] By making the moving direction of the carbon fibers 60 opposite to the flow direction of the treatment liquid, the surface treatment efficiency of the carbon fibers 60 is further improved.

[0065] Specifically, the fiber inlet 70 and the fiber outlet 80 are respectively located at the left and right ends of the washing tank 10 , the water inlet 11 and the fiber outlet 80 are located at the same end of the washing tank 10 , and the water outlet 12 and the fiber inlet 70 are located at the same end of the washing tank 10 .

[0066] In a possible implementation, the height of the partition 30 gradually decreases along the direction from the water inlet 11 to the water outlet 12 .

[0067] By distributing the height of the partition 30 in a stepped manner, when the treatment liquid in the washing tank 10 flows along the first direction X, the treatment liquid in the previous washing zone 31 can overflow from the upper end of the partition 30 to the next washing zone 31 in sequence, and the debris can be precipitated in different washing zones 31 respectively, so that the fluid enters each washing zone 31 through the liquid inlet 20 to push the precipitated debris to move to one side of the washing tank 10.

[0068] Specifically, the height of the partition 30 gradually decreases from the water inlet 11 to the water outlet 12, which means that the upper end surfaces of all the partitions 30 are compared, and the upper end surface of each partition 30 can be a horizontal plane. The lower ends of all the partitions 30 are located in the same plane.

[0069] Please continue reading Figure 1-Figure 3Optionally, the washing tank 10 is a square structure, which includes a tank bottom wall 95, a first side wall 91 and a second side wall 92 arranged opposite to each other, and a third side wall 93 and a fourth side wall 94 arranged opposite to each other. The first side wall 91, the third side wall 93, the second side wall 92 and the fourth side wall 94 are connected end to end to enclose the tank side walls of the washing tank 10, wherein the fiber inlet 70 is arranged on the first side wall 91, the fiber outlet 80 is arranged on the second side wall 92, a water inlet 11 is arranged below the fiber outlet 80 of the second side wall 92, and a water outlet 12 is arranged at a position of the tank bottom wall 95 close to the first side wall 91.

[0070] A plurality of partitions 30 are vertically arranged on the bottom wall 95 of the tank, and the two ends of each partition 30 are respectively connected to the third side wall 93 and the fourth side wall 94 opposite to each other. The partitions 30 divide the washing tank 10 into a plurality of washing zones 31, and a liquid inlet 20 is arranged at the third side wall 93 corresponding to each washing zone 31. A first guide roller 40 is arranged in each washing zone 31, and the two ends of the first guide roller 40 are respectively rotatably connected to the third side wall 93 and the fourth side wall 94 opposite to each other. A second guide roller 50 is arranged above each partition 30, and the two ends of the second guide roller 50 are respectively rotatably connected to the third side wall 93 and the fourth side wall 94 opposite to each other. Figure 1 Looking from above, the fourth side wall 94 has a plurality of through holes, and the through holes are used for installing the first guide roller 40 .

[0071] In a possible implementation, an exchange tank (not shown) is provided outside the water washing tank 10, and the water inlet 11 and the water outlet 12 are connected to the exchange tank through a pipeline, and a circulation pump is provided on the pipeline.

[0072] By providing an exchange tank, the treatment liquid in the washing tank 10 can always be in a flowing state, thereby improving the surface treatment efficiency of the carbon fiber 60, and the treatment liquid can be recycled to save resources.

[0073] Specifically, the exchange tank is used to store the treated liquid discharged from the washing tank 10. A filtering structure can be set in the exchange tank to filter impurities in the treated liquid. The treated liquid after filtration can enter the washing tank 10 through the water inlet through the pipeline for recycling.

[0074] In a possible implementation, the upper end of the washing tank 10 is an open structure.

[0075] Specifically, the upper end of the washing tank 10 may be always in an open state to facilitate observation of the state of the carbon fibers 60 .

[0076] A detachable shield may also be provided at the upper end of the water washing tank, one end of the shield being hinged to one side of the water washing tank 10, and the other end of the shield being connected to the other side of the water washing tank 10 by a buckle, so that when it is necessary to tow the carbon fiber 60 and make the carbon fiber 60 sequentially wind around the first guide roller 40 and the second guide roller 50, the shield can be opened.

[0077] When the carbon fiber 60 is in a state of continuous water washing, the protective cover can be closed to protect the water washing tank and prevent debris from falling onto the carbon fiber 60 or entering the treatment liquid in the water washing tank 10.

[0078] Protruding structures are arranged on both sides of the upper end of the washing tank 10 along the second direction Y. The two opposite protruding structures form a group of mounting structures for mounting the second guide roller 50. The second guide roller 50 has the same structure as the first guide roller 40 and is distinguished here for the convenience of understanding its position.

[0079] The first guide roller 40 and the second guide roller 50 are smooth flat rollers with an electroplated coating.

[0080] By setting the upper end of the washing tank 10 as an open structure, it is convenient to operate the carbon fiber 60, so that the carbon fiber 60 can be wound on the first guide roller 40 and the second guide roller 50 in sequence.

[0081] In a possible implementation, a plurality of universal wheels may be provided at the lower end of the washing tank 10 to facilitate the transfer of the washing tank 10 to different locations for use. At least one universal wheel may cooperate with a locking structure.

[0082] It should be further explained that the washing process of the carbon fiber 60 in the washing tank 10 can be as follows: first, the water outlet 12 is blocked, and the treatment liquid is injected into the washing tank 10 through the water inlet 11. When the treatment liquid in the washing tank 10 accumulates to a certain liquid level (the treatment liquid can completely immerse the first guide roller 40), the treatment liquid is stopped from being injected into the washing tank 10. Then, the staff pulls the carbon fiber 60 so that the carbon fiber 60 passes through the upper end of the first guide roller 40 and the lower end of the second guide roller 50 in sequence from the fiber inlet 70 to the fiber outlet 80. The end of the carbon fiber 60 located at the fiber outlet 80 can be connected to the winding structure, so that the carbon fiber 60 is in a slowly moving state. In the process of moving, the carbon fiber 60 is washed by the treatment liquid in the washing tank 10. During the washing process, the water outlet 12 can be opened, and the circulation pump can be started to control the amount of the treatment liquid injected into the washing tank 10 from the water inlet 11 and the amount of the treatment liquid discharged from the water outlet 12 to be the same, so that the treatment liquid in the washing tank 10 can move along the first direction X and maintain dynamic balance. The liquid inlet 20 is in a normally closed state, and the liquid inlet 20 can be opened regularly or according to the accumulation of debris in the washing area 31, and the treatment liquid can be injected into the washing tank 10 through the liquid inlet 20 to guide the debris in the washing area 31 to the side away from the liquid inlet 20. When the treatment liquid is injected into the washing tank 10 through the liquid inlet 20, the discharge amount of the water outlet 12 can be increased.

[0083] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
