Description

Technical Field

[0001] This utility model relates to the field of fiber textile production technology, specifically to a simple device for disassembling a stacked filter used in carbon fiber production. Background Technology

[0002] In the industrial production field, disc filters, as a high-efficiency filtration device, are widely used in water treatment, chemical industry, carbon fiber manufacturing and other industries. They achieve impurity separation through the precise combination of multiple discs. They need to be disassembled regularly to clean the filter residue and replace worn discs to ensure filtration efficiency.

[0003] Currently, the disassembly of disc filters used in the carbon fiber manufacturing industry relies heavily on manual labor and lacks specialized tooling. Operators typically use general-purpose tools such as wrenches, pry bars, and hammers to manually loosen the filter end caps and then remove the discs one by one. This traditional method has significant limitations:

[0004] Low operating efficiency: The filter lacks stable fixation and is prone to axial movement or radial displacement during disassembly. It requires repeated adjustment of the force points, and a single disassembly usually takes more than 30 minutes, which seriously affects the production and maintenance rhythm.

[0005] High risk of component damage: Uneven manual force can easily lead to deformation of the filter shell, stripping of the end cap threads, or damage to the edge of the stacked plates (especially for precision filters used in carbon fiber production, whose stacked plate material is more brittle and more easily damaged by impact).

[0006] Poor operational safety: The general-purpose tool does not fit well with the filter surface and is easy to slip when force is applied, which may cause cuts to the operator's hands or injury from the tool.

[0007] Insufficient versatility: Different specifications of disc filters (with differences in length and diameter) require different tools, which increases tool management costs, and frequent tool changes further reduce work efficiency.

[0008] Therefore, in response to the disassembly requirements of disc filters, it is necessary to develop a special disassembly device that is simple in structure, easy to operate, and highly adaptable, in order to solve the problems of low efficiency, vulnerable parts, and poor safety in the existing methods. This has become a practical need in the industry to improve equipment maintenance efficiency. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a simple device for disassembling disc filters used in carbon fiber production.

[0010] To achieve the above objectives, the technical solution of this utility model is as follows: a simple device for disassembling stacked filters used in carbon fiber production, comprising a workbench, on which a fixed baffle, a filter support base and a pressing mechanism are sequentially arranged, the fixed baffle, the filter support base and the pressing mechanism being arranged in a straight line, a transmission mechanism being provided at one end of the pressing mechanism, and a power cylinder for controlling the movement of the pressing mechanism being provided at the other end of the transmission mechanism.

[0011] In the above embodiments, this application constructs an integrated disassembly system that combines positioning, support, and clamping by arranging the fixed baffle, filter support, and clamping mechanism in a straight line on the worktable and coordinating the transmission mechanism with the power cylinder. The power cylinder provides a stable power source, which drives the clamping mechanism to precisely act on the filter via the transmission mechanism, forming an axial closed-loop constraint with the fixed baffle. This completely solves the problems of axial movement and radial displacement caused by the lack of stable filter fixation in traditional manual disassembly. Without the need for repeated adjustments to the force points, a single person can complete the filter fixing and disassembly operations. The time required for a single disassembly is significantly reduced compared to traditional methods, significantly improving work efficiency. Simultaneously, it lays a structural foundation for subsequent component protection and safe operation, adapting to the disassembly requirements of precision laminated filters in carbon fiber production.

[0012] In some embodiments, the fixed baffle, filter support, and clamping mechanism are all detachably mounted on the workbench.

[0013] In the above embodiments, the detachable design of the fixed baffle, filter support, and clamping mechanism of this application enables flexible adaptation of the device to multi-specification disc filters. For filters with different diameters, lengths, and end-face structures, matching fixed baffles (adjusting the positioning structure), filter supports (adapting to the shape), and clamping mechanisms (matching pressure requirements) can be quickly replaced without requiring dedicated disassembly tools for each filter specification. This significantly reduces tool management costs, avoids efficiency losses caused by frequent tool changes, and allows this application to cover the disassembly operations of various types of disc filters in carbon fiber production, improving equipment versatility and economic efficiency.

[0014] In some embodiments, a positioning block matching the number of disc filters is provided on one side of the fixed baffle.

[0015] In the above embodiments, the positioning blocks on the fixed baffle of this application, matching the number of disc filters, can be precisely embedded into the corresponding structure at the bottom of the filter, forming a circumferential limit. When disassembling the filter end cap requires rotational force, it effectively prevents the filter from rotating synchronously with the tool, ensuring that the force is precisely applied to the end cap threads or connectors, avoiding disassembly obstruction and force dispersion caused by filter rotation. Compared with traditional non-positioning disassembly, it significantly reduces the risk of end cap thread stripping, while reducing the operation time caused by repeated alignment, further improving disassembly efficiency and component protection.

[0016] In some embodiments, a pressure relief hole is provided at the center of the fixed baffle.

[0017] In the above embodiments, the pressure relief hole at the center of the fixed baffle can reduce the structural damage caused by overpressure, extend the service life of the equipment, and add safety redundancy to the operation process.

[0018] In some embodiments, a support block is provided on the side of the fixed baffle away from the filter support.

[0019] In the above embodiments, the support block on the side of the fixed baffle away from the filter support base forms a reverse support structure for the baffle, dispersing the axial pressure transmitted by the clamping mechanism to the worktable and preventing the fixed baffle from tilting or displacing due to excessive force at a single point. This ensures that the baffle maintains vertical positioning accuracy under high pressure, and the positioning block on its surface is always precisely fitted with the bottom of the filter, guaranteeing the stability of the filter's axial positioning. This solves the problem of "easy loosening of the positioning structure" in traditional manual disassembly, providing a continuous and reliable positioning reference for filter disassembly and indirectly reducing the risk of component damage.

[0020] In some embodiments, the filter support base has an arc-shaped structure in the middle.

[0021] In the above embodiments, the arc-shaped structure in the middle of the filter support base of this application closely fits the outer cylindrical surface of the laminated filter, increasing the support contact area and forming a wraparound support for the filter. Under the pressure of the filter's own weight and the clamping mechanism, it effectively prevents the filter from sliding laterally or even being thrown out of the support base during disassembly, eliminating the safety hazard of filter displacement in traditional planar supports. At the same time, the arc-shaped support can disperse the local force on the filter, avoiding deformation of the filter shell caused by concentrated support points. It is particularly suitable for the support needs of thin-walled precision filters in carbon fiber production, improving operational safety and the protection of filter integrity.

[0022] In some embodiments, the clamping mechanism includes a clamping block that moves along the worktable and a clamping rod that pushes the clamping block to move.

[0023] In the above embodiments, the clamping mechanism of this application consists of a clamping block that can move along the worktable and a clamping rod that pushes it to move, achieving precise control of the pressure application position. The clamping rod can convert the power transmitted by the transmission mechanism into axial pressure of the clamping block on the top of the filter, and the movement trajectory of the clamping block along the worktable ensures that the pressure application direction is consistent with the filter axis, avoiding uneven force on the filter due to force deviation. Compared with the point pressure of traditional tools such as pry bars, the surface contact clamping block can evenly distribute the pressure on the end face of the filter, reducing the risk of filter damage caused by excessive local pressure, while improving clamping stability and providing reliable axial constraint for disassembly operations.

[0024] In some embodiments, the shape of the clamping block matches the shape of the disc filter.

[0025] In the above embodiments, the shape of the clamping block matches the shape of the disc filter, enabling close-fitting pressure application. For filters with flat, curved, or irregular end faces, the matching shape of the clamping block increases the contact area, allowing the clamping force to be evenly transmitted to the top of the filter, avoiding localized stress concentration caused by insufficient contact area, and effectively protecting the filter end face and sealing surface from damage. Simultaneously, the close-fitting contact prevents the clamping block from slipping during pressure application, improving operational safety and further ensuring the stability of the filter's posture during disassembly.

[0026] In some embodiments, the transmission mechanism includes a fixed rod disposed on a workbench, the other end of the fixed rod being rotatably disposed on a transmission rod, one end of the transmission rod being hinged to a clamping rod, and the other end being hinged to a power cylinder.

[0027] In the above embodiments, the transmission mechanism of this application adopts a lever structure of a fixed rod and a transmission rod, which converts the linear power of the power cylinder into precise pressure application of the clamping mechanism, significantly saving power output by utilizing the lever principle. Under the same clamping effect, the rated power requirement of the power cylinder can be reduced, allowing the cylinder to generate sufficient clamping force within the conventional pressure range of 2-10 bar, avoiding increased costs and energy waste caused by excessive cylinder power. At the same time, the fixed rotation fulcrum of the lever structure ensures that the movement trajectory of the clamping mechanism is controllable, achieving precise control of the applied pressure and position, reducing power transmission loss, and improving the operational stability and energy efficiency of the device.

[0028] In some embodiments, the air pressure inside the power cylinder is 2-10 bar.

[0029] In the above embodiments, the 2-10 bar air pressure setting within the power cylinder of this application enables precise and controllable clamping force. For laminated filters of different wall thicknesses and materials, a suitable clamping force can be obtained by adjusting the air pressure: this avoids both insufficient pressure causing the filter to be loosely fixed and shifting during disassembly, and excessive pressure causing irreversible damage such as filter shell deformation and laminate breakage. Compared to the randomness of traditional manual force application, the controllable air pressure output reduces the fluctuation range of clamping force, increases the reusability of filters and laminates, significantly reduces spare parts replacement costs, and provides quantifiable assurance for operational safety.

[0038] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0039] It should be noted that in the fiber textile production field, carbon fiber production, as one of the core links, requires extremely high precision and stability from the production equipment. Disc filters, as key equipment for filtering spinning solution, effectively intercept impurities and ensure the quality of the raw yarn through their multiple layers of precision discs. However, because spinning solution contains high molecular weight polymers and trace impurities, the filters need to be disassembled, cleaned, or have their discs replaced regularly every 2-3 months. Disc filters used in carbon fiber production are mostly custom-designed, with brittle disc materials and high-precision sealing surfaces. The requirements for positioning accuracy and force stability during disassembly are far higher than for filters used in ordinary industries. Improper operation can easily lead to component damage, directly affecting production continuity and product quality.

[0040] In existing technologies, the disassembly of such precision disc filters still relies on a combination of manual labor and general tools. Multiple operators are required, using wrenches to pry open the end caps and hammers to loosen them. The entire process lacks a stable positioning and support structure. This not only results in a single disassembly often taking more than 30 minutes, slowing down equipment maintenance, but also causes uneven force application and filter slippage, leading to problems such as edge damage to the discs, stripped threads on the end caps, and deformation of the outer shell, increasing the disc scrap rate. Furthermore, frequent tool slippage and filter tipping pose safety hazards, threatening the personal safety of operators. Additionally, different sizes of filters require multiple sets of tools, increasing management costs.

[0041] Based on this, this application proposes a simple device for disassembling laminated filters used in carbon fiber production. Through the coordinated design of a worktable, fixed baffle, filter support, clamping mechanism, transmission mechanism, and power cylinder, positioning, support, and pressure functions are integrated into one unit. The core technical features are: the fixed baffle, filter support, and clamping mechanism are arranged in a detachable, linear configuration, working in conjunction with positioning blocks to achieve dual circumferential and axial limiting of the filter; the transmission mechanism uses a lever structure composed of a fixed rod and a transmission rod, converting the output of the 2-10 bar pneumatically driven power cylinder into a precise and controllable clamping force, achieving stable clamping of the laminated filter, precise force control, and multi-specification compatibility. This solves the core problems of low efficiency, high component damage rate, poor safety, and insufficient versatility in traditional disassembly methods.

[0042] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0043] As attached Figures 1 to 2 As shown, a simple device for disassembling a laminated filter used in carbon fiber production includes a workbench 1, a fixed baffle 2, a filter support 3, a pressing mechanism 4, a transmission mechanism 5, and a power cylinder 6.

[0044] The fixed baffle 2 is detachably fixed to the left end of the workbench 1 by bolts. A support block 201 is welded to the side of the fixed baffle 2 away from the filter support 3. The bottom of the support block 201 is tightly attached to the surface of the workbench 1 to form a triangular support structure. A positioning block 202 is integrally formed on the side of the fixed baffle 2 facing the filter support 3. The number of positioning blocks 202 matches the number of positioning holes at the bottom of the stacked filter to be disassembled. A pressure relief hole 203 is opened through the center of the fixed baffle 2. The pressure relief hole 203 is coaxially arranged with the filter axis.

[0045] The filter support 3 is detachably installed in the middle of the workbench 1 by bolts. Its top is an arc-shaped structure with an arc radius that matches the radius of the outer cylindrical surface of a commonly used disc filter. A rubber buffer layer with a thickness of 2-3mm is pasted on the arc surface to increase friction and buffer pressure.

[0046] The clamping mechanism 4 includes a clamping block 401 and a clamping rod 402. The clamping rod 402 is a rigid metal rod, one end of which is hinged to the clamping block 401 and the other end is hinged to the transmission mechanism 5. The side of the clamping block 401 facing the filter support 3 has an arc-shaped or planar structure that matches the top end face of the stacked filter. The bottom of the clamping block 401 is slidably connected to the slide rail on the worktable 1 through a slider, and can be translated along the axial direction of the worktable 1.

[0047] The transmission mechanism 5 consists of a fixed rod 502 and a transmission rod 501. The bottom end of the fixed rod 502 is horizontally welded to the right side of the workbench 1 near the edge, and the top end is rotatably connected to the transmission rod 501 at a position slightly above the middle through a pin, forming a lever fulcrum. One end of the transmission rod 501 is hinged to the end of the clamping rod 402 away from the clamping block 401, and the other end is hinged to the end of the piston rod of the power cylinder 6 through a pin.

[0048] The power cylinder 6 is fixed to the support at the bottom of the workbench 1 by the cylinder seat. Its air inlet is connected to the compressed air pipeline in the factory area through the quick-connect air pipe. The air pipe is equipped with a pressure regulating valve, which can stably control the air pressure in the cylinder at 2-10 bar. The extension and retraction direction of the piston rod of the power cylinder 6 is parallel to the axis of the workbench 1.

[0049] The specific usage method of this device is as follows, taking the disassembly of a φ150mm type disc filter commonly used in carbon fiber production as an example:

[0050] According to the filter specifications, select a fixed baffle 2 with two positioning blocks 202, a filter support 3 with an arc radius of 75mm and an arc-shaped clamping block 401, and fix them to the corresponding positions on the workbench 1 with bolts to ensure that the center lines of the fixed baffle 2, the filter support 3 and the clamping block 401 are collinear.

[0051] Place the disc filter to be disassembled horizontally on the arc-shaped surface of the filter support 3, and push the filter so that its left end fits against the fixed baffle 2, ensuring that the positioning block 202 is accurately embedded in the positioning hole at the bottom of the filter, thus completing the initial circumferential and axial positioning.

[0052] Open the compressed air valve and adjust the pressure regulating valve to 5 bar. The piston rod of the power cylinder 6 extends, pushing the transmission rod 501 to rotate around the fulcrum at the top of the fixed rod 502. The other end of the transmission rod 501 drives the clamping rod 402 to push the clamping block 401 along the slide rail towards the filter until the clamping block 401 is tightly pressed against the top end face of the filter and a stable pressure is applied. At this time, the filter is firmly clamped between the fixed baffle 2 and the clamping block 401, without axial movement or radial displacement. If a sudden increase in pressure occurs during the process, the pressure relief hole 203 can quickly release the accumulated pressure between the filter and the baffle to avoid damage to the components.

[0053] The operator holds a wrench and rotates to disassemble the end cap on the right side of the filter. Because the positioning block 202 restricts the rotation of the filter, the force can be applied precisely to the end cap thread to avoid stripping. After the end cap is disassembled, the internal stacked plates are pulled out one by one. The arc-shaped structure of the filter support 3 and the rubber buffer layer can effectively prevent the filter from tipping over or the outer shell from deforming.

[0054] After all the stacked discs are removed, the compressed air valve is closed, the piston rod of the power cylinder 6 retracts, and the clamping block 401 is reset; the air filter housing is removed from the filter support 3 to complete the disassembly.

[0055] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
