Description

Technical Field

[0001] This utility model relates to the field of lithium battery production equipment technology, specifically to a device for recovering residual slurry in a filter, and more particularly to a filter element slurry recovery device. Background Technology

[0002] In the preparation and transportation of lithium battery electrode slurry, precision filters are required to remove impurities. Currently, the commonly used integrated filters typically have one-way valves (such as spring-return one-way valves) at both the inlet and outlet to ensure the sealing and controllable flow direction of the filtration process.

[0003] However, this design reveals a significant flaw when the filter cartridge reaches the end of its service life and needs to be replaced: Because both ports are one-way valves, when the filter is removed from the pipeline, its internal valve core automatically closes and remains sealed under the action of a restoring force (such as spring force). This prevents a large amount of high-value slurry remaining in the filter's internal cavity from being discharged naturally, ultimately forcing it to be scrapped along with the discarded filter, resulting in serious waste of raw materials and increased production costs.

[0004] Existing technical solutions mainly focus on the filtration efficiency and sealing performance of the filter itself, lacking a dedicated device for the effective and convenient recovery of residual slurry during filter replacement. Summary of the Invention

[0005] One of the objectives of this utility model embodiment is to provide a filter cartridge slurry recovery device that can overcome the obstruction of one-way valves and safely and efficiently recover residual slurry in the filter, thereby solving the practical technical problem of slurry waste.

[0006] This utility model provides a filter cartridge slurry recovery device for recovering residual slurry in a filter with a one-way valve, comprising: A fixture for receiving and recycling the filter; An ejector component, disposed on the fixture, applies mechanical force to the valve core of the one-way valve when the filter is positioned on the fixture, thereby driving the valve core to move from the closed position to the open position, forming a channel for the discharge of the residual slurry.

[0007] Optionally, the fixture includes at least one fixture unit. The top of the fixture unit is provided with a receiving cavity, the shape of which matches the shape of the end of the filter where the one-way valve is located, for supporting and positioning that end; The bottom of the accommodating cavity is provided with an upwardly positioned ejector component. When the filter is positioned in the accommodating cavity, the ejector component pushes open the valve core.

[0008] Optionally, a supporting crossbeam is provided at the bottom of the accommodating cavity. The ejector component is a pin fixed to the top surface of the support beam.

[0009] Optionally, it also includes: The lifting device is fixed to the cabinet. A filter fixing part is used to fix the other end of the filter and is connected to the output end of the lifting device; The lifting device is configured to drive the filter fixing part together with the filter fixed thereto to move up and down, so that the one-way valve end of the filter enters or leaves the fixture.

[0010] Optionally, the filter fixing part is a pressure block, and the pressure block is provided with mounting holes for the filter to pass through and be fixed.

[0011] Optionally, a guide block is provided below the filter fixing part. The guide block is provided with a guide surface that matches the shape of the outer wall of the filter, which is used to guide the lifting and lowering movement of the filter during the lifting and lowering process.

[0012] Optionally, the guide block has a block-shaped structure, and the guide surface is an arc-shaped surface that fits against the outer periphery of a portion of the filter facing it.

[0013] Optionally, a waste collection platform is provided below the fixture for placing waste collection containers.

[0014] Optionally, the waste collection platform is provided with a positioning part for fixing the waste collection container. Optionally, it also includes a storage compartment on the cabinet for storing the filter.

[0015] Alternatively, the storage compartments can be drawer-type or open shelf-type.

[0016] Optionally, the working heights of the filter fixing part, the fixture, the waste collection platform, and the collection bin are arranged in a top-to-bottom order.

[0017] Optionally, it also includes a control module and a touch screen electrically connected to the control module; The control module is configured to control the operation of the lifting device in response to the operation commands of the touch screen.

[0018] Optionally, the positioning unit is further provided with a weighing sensor, which is electrically connected to the control module; The control module is configured to trigger an alarm when the weight detected by the weighing sensor reaches a set threshold.

[0019] Optionally, it also includes indicator lights disposed on the cabinet to indicate the working status of the filter slurry recovery device.

[0020] As can be seen from the above, the filter slurry recovery device of this embodiment directly addresses the fundamental problems in the background technology. Its beneficial effects are significant: 1) Achieve slurry recovery: The external ejector component actively opens the one-way valve, allowing the discharge of residual slurry that could not be recovered in the past for reuse. According to experimental comparison, for a common filter with a capacity of 2 liters, an average of about 350-450 ml of residual slurry can be recovered, with a recovery rate of over 95%, while the recovery rate of traditional disposal methods is 0%.

[0021] 2) Simple structure and extremely low cost: It consists of a jig and an ejector component, which are easy to manufacture and maintain and easy to promote.

[0022] 3) Protects the filter structure: No need to damage the filter body, operation is non-invasive, and the filter can be reused after cleaning, further enhancing the application value of the filter.

[0023] In this embodiment, the "ejector component" can be any component capable of pushing, such as an ejector pin, ejector rod, or wedge block. The method of applying mechanical force is not limited to pressing down the filter; it can also involve the ejector component actively moving upwards. The "positioning" can be achieved through any mechanism that can limit the filter's position, such as grooves, stops, or grippers on a fixture. Experiments show that using a rigid ejector pin, compared to a flexible head, can more reliably overcome spring force, achieving a 100% valve core opening success rate, while a flexible head may have the risk of opening failure due to insufficient pressure.

[0032] See Figures 1-2 .

[0033] The present invention provides a device for recovering residual slurry in an integrated filter 3 with a one-way valve. It actively opens the one-way valve by physical means to realize the recovery of slurry, thereby solving the problem of slurry waste caused by the inability to open the valve in the prior art.

[0034] The filter cartridge slurry recovery device provided in this embodiment mainly includes a jig 1 and an ejector component 2.

[0035] The fixture 1 serves as the operating base, used to support and position the integrated filter 3 to be recycled. The ejector 2 is fixedly installed at a specific position on the fixture 1 so that the ejector 2 is opposite to the one-way valve of the filter 3 positioned on the fixture 1, thereby opening the valve core of the one-way valve.

[0036] During operation, the integrated filter 3, containing residual slurry and equipped with one-way valves at the inlet / outlet, is placed on fixture 1, ensuring correct positioning. Once the filter 3 is in place, the ejector component 2 on fixture 1 abuts against or aligns with the valve cores of each one-way valve on the filter 3. By manually pressing down on the filter 3 or through other driving methods, the ejector component 2 applies a mechanical force to the valve cores. This mechanical force overcomes the internal reset force of each one-way valve core (usually provided by a spring), driving the valve cores from the normal closed position to the open position. Once the valve cores are opened, the sealed cavity inside the filter 3 connects to the outside through the opened valves, forming a discharge channel. The residual slurry inside can then smoothly discharge through this channel under gravity, flowing into a pre-prepared collection container.

[0037] As can be seen from the above, the filter slurry recovery device of this embodiment directly addresses the fundamental problems in the background technology. Its beneficial effects are significant: 1) Achieve slurry recovery: The external ejector component 2 actively opens the one-way valve, allowing the residual slurry that could not be recovered in the past to be discharged and reused. According to experimental comparison, for a common filter 3 with a capacity of 2 liters, an average of about 350-450 ml of residual slurry can be recovered, with a recovery rate of over 95%, while the recovery rate of traditional disposal methods is 0%.

[0038] 2) Simple structure and extremely low cost: It consists of a jig 1 and an ejector component 2, which are easy to manufacture and maintain and easy to promote.

[0039] 3) Protect the structure of filter 3: No need to damage the filter 3 body, the operation is non-invasive, and filter 3 can still be reused after cleaning, which further enhances the application value of filter 3.

[0040] In this embodiment, the "ejector component 2" can be any component capable of pushing, such as an ejector pin, ejector rod, or wedge block. The method of applying mechanical force is not limited to pressing down the filter 3; it can also be that the ejector component 2 actively moves upward. "Positioning" can be achieved through any mechanism on the fixture 1 that can restrict the position of the filter 3, such as grooves, stops, or grippers. Experiments show that using a rigid ejector pin, compared to a flexible head, can more reliably overcome spring force, achieving a 100% valve core opening success rate, while a flexible head may have the risk of opening failure due to insufficient pressure.

[0041] As an illustration of this embodiment, in order to further optimize the convenience and accuracy of operation, the fixture 1 and the ejection component 2 are specifically designed.

[0042] The fixture 1 in this embodiment includes at least one independent fixture unit. Each fixture unit has a receiving cavity 11 machined or mounted on its top. The bottom of the receiving cavity 11 is provided with an ejector component 2 corresponding to the one-way valve at the end of the filter 3, and the ejector component 2 is oriented upwards. In this embodiment, the bottom of the receiving cavity 11 is not completely closed, but is provided with a supporting beam. The ejector component 2 specifically comprises at least one ejector pin (i.e., one or more ejector pins), which is vertically fixed at a designated position on the top surface of the supporting beam.

[0043] The shape of the receiving cavity 11 is designed to match the shape of the lower end of the integrated filter 3 (i.e., the end where the check valve is installed), for example, by creating a complementary cylindrical recess for initial positioning. The number of ejector pins and their distribution at the bottom of the receiving cavity 11 correspond precisely to the number and spatial position of the check valves at the end of the filter 3 to be recycled. For example, for the common filter 3 model with two check valves at the end (inlet and outlet), two ejector pins are installed at the bottom of the receiving cavity 11. The lateral position of these two ejector pins is precisely aligned with the center of the inlet valve core and the outlet valve core after the filter 3 is in place. When the lower end of the filter 3 is placed into this receiving cavity 11 and pressed into place, the two ejector pins can simultaneously and accurately abut and open the two valve cores.

[0044] Due to the shape matching of the receiving cavity 11 and the precise alignment of the ejector pins, when the filter 3 is lowered into place, all the one-way valve cores at its bottom are simultaneously pressed against the corresponding ejector pin tips and continuously exert force. As the filter 3 continues to be lowered or fixed, the upward mechanical force provided by the ejector pins is sufficient to overcome the spring return force of each valve core, thereby stably pushing it open to the open position. At this time, the internal cavity of the filter 3 is fully connected to the outside through all the opened valves, forming a complete discharge channel to ensure that residual slurry can be completely and quickly discharged.

[0045] As can be seen from the above, the further beneficial effects of applying the solution of this embodiment are as follows: 1) The position and shape of the ejector pin and the one-way valve correspond one-to-one, ensuring that all valve cores are opened synchronously and reliably. Experimental verification shows that for the dual-valve filter 3, this design increases the slurry complete emptying rate from the residue that may exist when opening at a single point (about 5-15%) to nearly 100%.

[0046] 2) This design principle can be flexibly expanded. For filters 3 of different models, with different quantities (such as one or three) or different layouts of check valves, they can be adapted simply by replacing or adjusting the fixture unit and the pin configuration, which greatly improves the applicability of the device.

[0047] 3) The support structure provides a rigid installation foundation while ensuring the consistency of the movement of multiple ejector pins and allowing the ejected slurry to flow smoothly down from the gap.

[0048] It should be noted that the ejector component 2 is not limited to an ejector pin. For check valves with special valve core structures, a suitable ejector head (such as a flat head or a fork head) can also be used. The support structure can be a bracket customized according to the valve port position, rather than a simple beam. In cases where multiple valve cores need to be ejected, it can be ensured that each ejector pin is connected through a common mounting plate to guarantee their relative positional accuracy.

[0049] As a further optimization of this embodiment, the device further includes a fixed cabinet 4. A lifting device 5 (such as a cylinder or electric push rod) is installed on the upper part of the cabinet 4. The output end of the lifting device 5 is connected to a filter fixing part 6 for clamping the upper end of the filter 3. Directly below the filter fixing part 6, a guide block 7 is fixedly installed on the cabinet 4. The fixture 1 is located below the guide block 7 and fixed to the middle of the cabinet 4.

[0050] The operator first secures the upper end of the filter 3 to the filter fixing part 6 (e.g., by inserting it into the mounting hole of the pressure block and locking it with fasteners). The lifting device 5 is then activated via the control system (e.g., a button or touchscreen 46). The lifting device 5 drives the filter fixing part 6 and the entire filter 3 it holds to descend vertically. During descent, the outer wall of the filter 3 contacts and slides against the pre-set guide surface on the guide block 7. The guide surface matches the shape of the outer wall of the filter 3 (e.g., for a cylindrical filter 3, the guide surface is a concave arc surface). This design effectively corrects any slight tilting that may occur in the filter 3, ensuring its movement trajectory is strictly vertical. The filter 3 finally descends precisely into the receiving cavity 11 of the fixture 1, and the ejector pin opens the valve core. After discharge, the lifting device 5 rises, the valve core resets and closes under the action of the spring, and the filter 3 is lifted back to its original position.

[0051] The further beneficial effects of this optimization scheme are as follows: 1) The operation is automated and labor-saving, eliminating the physical labor of manually handling and pressing the filter 3, and is especially suitable for heavy-duty or high-temperature filters 3. Experiments show that for filters 3 weighing more than 5kg, automated operation reduces the labor intensity of workers by more than 90% and completely avoids safety accidents caused by unstable manual operation.

[0052] 2) High precision and reliability: The guiding mechanism ensures the repeatability of positioning accuracy with each descent, making the alignment of the ejector pin and valve core foolproof, achieving a 100% opening success rate, and protecting the ejector pin and valve core from damage caused by off-center load.

[0053] 3) Scalability: This architecture allows multiple fixture units and corresponding lifting and fixing parts to be arranged side by side on the same cabinet 4, enabling simultaneous material discharge of multiple filters 3, resulting in a significant increase in efficiency. Actual test data shows that the assembly time for assembling two filters 3 in a dual-station device is only about 15% longer than the assembly time for assembling a single filter 3, demonstrating a significant improvement in efficiency.

[0054] The lifting device 5 mentioned above can be a screw and nut mechanism, a chain lifting mechanism, or a cylinder drive, etc. The filter fixing part 6 can be a robotic arm, pneumatic gripper, etc. The guide block 7 can be a complete guide sleeve, but is preferably a block structure with an arc-shaped surface that fits against the outer periphery of the filter 3. Compared with a fully enclosed guide sleeve, the block structure is more convenient for the lateral installation and disassembly of the filter 3, and has lower manufacturing costs and is less prone to the accumulation of residue.

[0055] As an illustration of this embodiment, when the lifting device 5 is pneumatically controlled, the pneumatic system can be implemented using existing methods, such as including a cylinder as an actuator, a solenoid valve for controlling the direction and on / off of airflow, a pneumatic triplet (filter 3, pressure reducing valve, lubricator) for providing a dry and stable air source, and corresponding air lines. The piston rod of the cylinder of the lifting device 5 serves as the output end and is connected to the filter fixing part 6 (such as a pressure block) to clamp the upper end of the filter 3. Directly below the filter fixing part 6, a guide block 7 is fixedly installed on the cabinet 4. The fixture unit is located below the guide block 7 and fixed to the middle of the cabinet 4.

[0056] The operating principle is as follows: the operator first fixes the upper end of filter 3 to filter fixing part 6. Automatic cycling is initiated via the control system (such as touchscreen 46). The control module issues a command to drive the pneumatic solenoid valve to switch, allowing compressed air to enter the rodless chamber of the cylinder, pushing the piston rod to drive the filter fixing part 6 and the entire filter 3 it holds to descend vertically and smoothly. The pneumatic system can precisely control the output force and descent speed by adjusting the pressure reducing valve, and utilizes the cylinder's own buffering function to achieve a smooth descent. During the descent, the outer wall of filter 3 contacts and slides against the pre-set guide surface on guide block 7. This design effectively corrects any slight tilting and ensures its movement trajectory is strictly vertical. Filter 3 finally descends precisely into the receiving cavity 11 of fixture 1, and the ejector pin opens the valve core. During discharge, the cylinder remains in the extended position, using a constant holding force to overcome the valve core's reset force, ensuring the valve remains open. After discharge, the control module controls the solenoid valve to switch, allowing compressed air to enter the rod chamber of the cylinder, the piston rod retracts, lifting filter 3 to its original position, and the valve core automatically resets and closes under spring action.

[0057] The beneficial effects of using the pneumatically controlled lifting device 5 are as follows: 1) Automated operation, high efficiency and labor saving: Pneumatic drive realizes complete automation of operation, eliminating manual labor. The pneumatic system has a fast response speed, which significantly shortens the time of a single lifting cycle. The measured average cycle (including discharge dwell time) is about 25% faster than that of electric screw drive.

[0058] 2) Powerful, stable, and reliable, the compressed air provides a large and constant force, reliably pressing down the heavy-duty filter 3 and overcoming the reset force of multiple valve cores. In industrial environments, the pneumatic system is resistant to contamination, easy to maintain, and has a low failure rate, making it particularly suitable for scenarios involving conductive slurries. Compared to pure electric drives, it offers higher safety.

[0059] 3) Extremely high precision and reliability. The combination of pneumatic drive and mechanical guidance ensures the repeatability of positioning accuracy for each descent, enabling a 100% success rate in aligning multiple ejector pins with multiple valve cores, and protecting the ejector pins and valve cores from damage caused by off-center loads.

[0060] 4) Cost and scalability advantages: Pneumatic components are relatively inexpensive, and the system is simple to build. This architecture allows for the parallel connection of multiple cylinders on the same pneumatic system, enabling synchronous material discharge at multiple workstations with minimal cost increases during expansion.

[0061] It should be noted that the power source of the lifting device 5 is not limited to pneumatic power; it can also be an electric push rod, a ball screw module driven by a servo motor (with higher precision and programmable complex speed curves), or a chain / belt lifting mechanism. The filter fixing part 6 can be a robotic arm, pneumatic gripper, etc. The guide block 7 can be a complete guide collar, but is preferably a block structure with an arc-shaped surface that fits against the outer periphery of the filter part 3, which facilitates installation and prevents material accumulation.

[0062] As a further optimization of this embodiment, the filter slurry recycling device of this embodiment can be set up as a complete, clean and user-friendly filter slurry recycling workstation, adding waste collection and old parts storage functions, and optimizing the overall layout.

[0063] Specifically, a waste collection platform 42 is provided directly below the fixture mounting platform 1 fixed to the cabinet 4. A waste collection bin 8 can be placed on the platform, and a positioning part 43 (such as a recessed retaining ring or stop) is provided to prevent the bin from shifting. Further below or to the side of the cabinet 4, a storage compartment 44 is provided for temporarily storing emptied or untreated filters 3. The filter fixing part 6 (high position), fixture 1 (middle position), waste collection platform 42 (lower middle position), and storage compartment 44 (lower position) are arranged sequentially from top to bottom in the cabinet 4 according to the usage flow. Furthermore, multiple lockable casters 45 are preferably installed at the bottom of the cabinet 4.

[0064] During application, the slurry discharged from the valve core of filter 3 drips vertically under gravity, directly into the collection tank 8 located directly below fixture 1, resulting in the shortest path and no splashing. The operation process is as follows: the operator retrieves or places filter 3 from the high-position fixed part → performs automatic discharge at the middle-position fixture 1 → replaces or removes the full collection tank 8 at the lower-middle platform → stores or retrieves the emptied filter 3 in the low-position storage bin 44. The entire process is Z-shaped or a straight downward flow, conforming to the human movement trajectory of continuous operation. When the equipment needs cleaning, maintenance, or adjustment of the work position, the locking device of the casters 45 can be loosened to easily push the entire device to the target position, and then relocked to ensure stability during operation.

[0065] The further beneficial effects of adopting this integrated filter cartridge slurry recovery workstation are as follows: 1) The vertical drop design maximizes the use of gravity, preventing slurry from lingering inside the device or contaminating the equipment, achieving 100% collection efficiency. The positioning part 43 prevents the collection bucket 8 from tipping over, ensuring operational safety.

[0066] 2) The dedicated storage compartment 44 provides a fixed storage point for discarded or unused filters 3, avoiding clutter on site and improving the level of 5S management.

[0067] 3) This workstation adopts a top-to-bottom layout, allowing operators to complete all procedures with minimal body movement and the shortest operating path while remaining largely standing, significantly reducing fatigue and improving work efficiency. Experimental studies show that compared to traditional repair stations with components scattered throughout, this integrated layout reduces the average time to complete a single task by approximately 30%.

[0068] 4) The lockable casters 45 at the bottom greatly enhance the mobility of the equipment. This allows the recycling device to function as an independent workstation, flexibly serving multiple production lines or adjusting its position according to production rhythm, and also facilitates daily cleaning and equipment maintenance. Locking effectively prevents the equipment from sliding during operation, ensuring operational safety and accuracy.

[0069] It should be noted that a weighing sensor (not shown in the figure, but existing technology can be used) can be installed on the waste collection platform 42 in this embodiment, connected to the control system, and automatically alarms when the collected slurry reaches the set weight. The collection compartment 44 can be a drawer, an open shelf, or a box with wheels for easy access and transport. The number of casters 45 is usually four, and models with foot pedal locking or brake pad locking can be selected to adapt to different ground conditions. For permanent workstations, adjustable feet can also be provided as a fixing solution, interchangeable with the caster 45 module.

[0070] As a further illustration of this embodiment, in order to improve the intelligence level of the device and the user experience, the filter slurry recovery device of this embodiment also integrates a control system and a human-machine interface.

[0071] Specifically, the filter cartridge slurry recovery device is equipped with a control module (such as a PLC or microcontroller) and a touch screen 46 (human-machine interface, HMI) electrically connected to it. The output of the control module controls the operation of the lifting device 5. An indicator light 47 (such as a tri-color light) is installed in a prominent position (such as the top or front) on the cabinet 4, which is also controlled by the control module.

[0072] The operating principle is as follows: the operator selects the operating mode (such as single run, dual-station synchronous), start, or emergency stop via the touchscreen 46. After receiving the command, the control module precisely controls the lifting speed, stroke, and dwell time of the lifting device 5. For example, in "automatic discharge" mode, the device automatically executes a cycle of "descent-dwell (discharge)-ascent". Indicator lights 47 display the device status in real time: solid green light (standby), flashing yellow light (running), solid red light (fault or emergency stop). The entire operation process requires no bending over or large movements; all control can be easily completed on the touchscreen 46.

[0073] The further beneficial effects of adopting this intelligent control system are as follows: 1) Intelligent and standardized operation: Through program control, parameters such as discharge time can be precisely set and kept consistent, avoiding the uncertainty of manual operation and ensuring the reproducibility of the recycling process.

[0074] 2) Status is clear at a glance: The sound and light (can be combined with a buzzer) indications enable the equipment status to be quickly identified remotely even in noisy workshop environments, improving equipment management efficiency.

[0075] The control input is not limited to the touchscreen 46; it can also be a physical button, knob, or remote wireless control. Indicator lights 47 can be integrated into the UI of the touchscreen 46, but standalone physical lights are generally more reliable in industrial environments. The control module can be further networked to connect to the factory's MES (Manufacturing Execution System) for data uploading and remote monitoring.

[0076] The above embodiments do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
