[0028] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] This utility model discloses a leaf filter press disassembly tool, which can solve the technical problem of time-consuming and labor-intensive manual replacement in the prior art, thereby effectively improving the leaf filter cloth replacement efficiency and reducing labor intensity and labor costs.

[0030] The technical solution of this application will be described in detail below through specific embodiments:

[0031] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses a leaf filter press disassembly tool, which includes a support structure 100, a lifting structure 200, and a control structure 300. The support structure 100 includes a support frame 110 and two support clips 120, which are respectively installed at both ends of the support frame 110. The lifting structure 200 includes a lifting frame 210 and at least two hooks 220, which are sequentially arranged on the lifting frame 210, and the straight line of each hook 220 is parallel to the straight line of the two support clips 120. The control structure 300 includes a first connecting member 310, a second connecting member 320, and a control rod 330. The first connecting member 310 is installed on the support frame 110, and the second connecting member 320 is installed on the lifting frame 210. Both the first connecting member 310 and the second connecting member 320 are connected to the control rod 330, which is used to drive the second connecting member 320 to move up and down relative to the first connecting member 310.

[0032] The leaf filter press disassembly tool disclosed in this embodiment reduces the time required for traditional manual operation, thereby improving the overall fabric replacement efficiency. The automation and convenience make the operation simpler, reducing manpower requirements and lowering labor costs.

[0033] In one embodiment, one of the first connector 310 and the second connector 320 is threadedly connected to the control lever 330, and the other is rotatably or threadedly connected to the control lever 330.

[0034] When the first connector 310 or the second connector 320 is threadedly connected to the control lever 330, the self-locking nature and precise transmission ratio of the thread ensure highly accurate lifting and lowering movement of the lifting structure 200 (connected to the second connector 320) relative to the support structure 100 (connected to the first connector 310). Workers can precisely control the movement distance of the lifting structure 200 by rotating the control lever 330, thereby enabling precise operation of the pressure block disassembly process and preventing damage to the pressure block or incomplete disassembly due to improper movement distance.

[0035] Another connector is either rotatably or threadedly connected to the control lever 330, providing operational flexibility. A rotatable connection allows the connector to maintain its relative position as the control lever 330 rotates (moving only when the control lever 330 moves axially), while a threaded connection enables more precise control.

[0036] Workers can simply rotate the control lever 330 to raise and lower the lifting structure 200 without performing complicated operations or using additional tools, simplifying the operation process and reducing the difficulty of operation.

[0037] In one embodiment, both the first connector 310 and the second connector 320 are threadedly connected to the control lever 330, and the threads on the first connector 310 and the second connector 320 have the same direction of rotation.

[0038] When the control lever 330 rotates, the first connector 310 and the second connector 320 will move axially along the control lever 330 synchronously and in the same direction (when only considering the effect of the threaded connection, the actual direction of movement needs to be determined in conjunction with the relative positional relationship between the support frame 110 and the lifting frame 210; here, the emphasis is on the synchronous movement trend based on the thread direction). This synchronous movement mechanism ensures that the lifting structure 200 can rise or fall stably and smoothly, reducing swaying or jamming caused by asynchronous movement and improving the stability and accuracy of the disassembly process.

[0039] Furthermore, since the threads on the first connector 310 and the second connector 320 are in the same direction, compared to the control lever 330 being threadedly connected to only one of the first connector 310 and the second connector 320, the control lever 330 can raise the lifting structure by two units when rotating by a unit angle, thereby achieving rapid control of the position of the lifting structure 200.

[0040] In one embodiment, the length of the riser 210 is less than the length of the support frame 110, and each hook 220 is located between two support hooks 120.

[0041] During disassembly, the support clip 120 can make wider contact with and provide stable support to the relevant fixed parts of the leaf filter, providing a solid and reliable point of force for the entire tool. This effectively prevents the tool from tilting, shaking, or even overturning due to uneven force during use, ensuring that the disassembly operation is carried out in a stable state.

[0042] The hook 220 is located between the two support clips 120. This layout provides the hook 220 with a clear spatial positioning reference. When disassembling the leaf filter press block, the hook 220 can more accurately hold the press block, reducing disassembly difficulties or damage to the press block caused by positioning deviations.

[0043] The reasonable length difference and the arrangement of the hook 220 position avoid interference between the lifting frame 210 and its hook 220 and other parts of the leaf filter during the lifting process, ensuring the smooth disassembly operation and improving the accuracy and success rate of disassembly.

[0044] In one embodiment, the support card 120 is arc-shaped to form a limiting groove 121, and the hook 220 is also arc-shaped to form a gripping groove 221, with the limiting groove 121 and the gripping groove 221 set at an angle.

[0045] The support clip 120 features an arc-shaped limiting groove 121 that closely conforms to the contours of the relevant support parts of the leaf filter, providing a stable support base for the entire tool. This design reduces tool wobbling and offset during use, ensuring stability during disassembly or installation operations.

[0046] The hook 220 has an arc-shaped gripping groove 221, which can better adapt to the shape of the leaf filter block and provide a tighter gripping effect. The arc design of the gripping groove 221 increases the contact area between the hook 220 and the block, improves friction, and thus ensures that the block will not easily fall off during disassembly.

[0047] In one embodiment, the limiting groove 121 is arranged perpendicularly to the gripping groove 221.

[0048] The vertically positioned limiting groove 121 and gripping groove 221 enable the tool to better adapt to different models and specifications of leaf filters, and prevent the rising structure 200 from colliding with the support structure 100 when it rises.

[0049] In one embodiment, the control structure 300 further includes a drive assembly that is drive-connected to the control lever 330.

[0050] The addition of the drive assembly means that the rotation of the control lever 330 no longer relies entirely on manual operation, but can be automated or semi-automated through the drive assembly. This greatly reduces the workload of operators and improves work efficiency.

[0051] The drive assembly typically has a high response speed and precise control capability, enabling it to execute control commands quickly and accurately, causing the control lever 330 to rotate at a predetermined speed and angle, thereby achieving precise lifting and lowering of the lifting structure 200 and improving the accuracy of disassembly or installation.

[0052] In one embodiment, the drive component includes at least one of an electric wrench and a servo motor.

[0053] An electric wrench is a portable and easy-to-operate power tool that allows for rapid rotation of the control lever 330 to achieve the lifting action of the ascending mechanism 200. Electric wrenches typically have high torque output, capable of handling significant resistance during disassembly, and are easy to operate, making them suitable for use in various environments.

[0054] Servo motors, on the other hand, are more precise and controllable drive devices. They can accurately adjust rotation speed and angle according to control signals, achieving finer control. Servo motors also feature fast response speed and accurate positioning, making them suitable for scenarios requiring high disassembly precision.

[0055] It offers two options: electric wrench and servo motor, allowing for flexible combinations based on actual work needs, operating environment, and budget, thus meeting the diverse needs of different users.

[0056] In one embodiment, the support frame 110 includes a support plate 111 and two legs 112. The two legs 112 are respectively disposed at both ends of the support plate 111. Two support clips 120 are disposed in a one-to-one correspondence with the two legs 112, and the support clips 120 are located at the ends of the legs 112 opposite to the support frame 110.

[0057] The support plate 111, as the main load-bearing part of the support frame 110, provides a solid foundation for the overall structure. The two legs 112 are respectively set at both ends of the support plate 111. This symmetrical layout helps to distribute the weight, maintain the balance and stability of the support frame 110, and reduce tilting or swaying caused by uneven force.

[0058] Two support clips 120 are configured in a one-to-one correspondence with two support legs 112. This design allows the support clips 120 to be flexibly adjusted according to the specific structure and position of the leaf filter. The support clips 120 on each support leg 112 can independently adapt to different parts of the leaf filter, improving the adaptability and flexibility of the tool.

[0059] In one embodiment, the lifting frame 210 includes a connecting plate 211 and at least two connecting legs 212. The connecting legs 212 are spaced apart along the length of the connecting plate 211. The number of connecting legs 212 is equal to the number of hooks 220, and each connecting leg 212 corresponds to one hook 220. The hooks 220 are located at the end of the connecting leg 212 opposite to the connecting plate 211.

[0060] The connecting plate 211 serves as the basic structure of the ascending frame 210, providing a stable support platform for the entire ascending frame 210. At least two connecting legs 212 are spaced apart along the length of the connecting plate 211. This arrangement helps to distribute the forces generated during the ascent, maintain the balance and stability of the ascending frame 210, and reduce deformation or swaying caused by uneven force distribution.

[0061] The connecting legs 212 are spaced apart along the length of the connecting plate 211, providing operators with sufficient operating space to facilitate their access to and operation of the hooks 220, thereby improving the efficiency of gripping and disassembling the leaf filter press blocks.

[0062] Since each connecting leg 212 is configured to correspond one-to-one with a hook 220, the hook 220 can be positioned more accurately when gripping the pressure block, reducing the risk of gripping failure or pressure block damage due to positional deviation.

[0063] Through the above embodiments, this application has the following beneficial effects or advantages: The leaf filter press block disassembly tool disclosed in this application adopts a specially designed support structure 100, lifting structure 200, and control structure 300, which can quickly and accurately disassemble the press block and other auxiliary parts of the vertical leaf filter. Compared with traditional manual tools, it greatly shortens the cloth changing time and improves production efficiency. A drive component, such as an electric wrench or servo motor, is added to the tool. The drive component drives the control rod 330 to rotate, realizing the lifting and lowering of the lifting structure 200, thereby reducing the labor intensity of workers and making the disassembly process easier. Both the support clip 120 and the hook 220 are arc-shaped, and the axis of the hook 220 is set at an angle to the axis of the support clip 120, which can better adapt to the structure of the leaf filter, improve the fit between the tool and the leaf filter, increase the stability during the disassembly process, and reduce the occurrence of accidents such as press block detachment.
