Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium salt purification technology, and in particular to a filter for lithium carbonate purification with a quick-release filter element. Background Technology
[0002] In the lithium carbonate purification process, filtration is a crucial step in removing insoluble impurities, fine particles, and colloidal substances from the solution, directly affecting the purity and quality of the final product. As the core equipment in this process, the performance and ease of operation of the filter significantly impact production efficiency and operating costs. An ideal filter for lithium carbonate purification not only needs excellent filtration accuracy and sealing performance to withstand complex chemical environments and operating pressures, but also requires an efficient filter element replacement mechanism to address the need for frequent replacements after filter element clogging, thereby reducing downtime and improving the continuity and automation level of the production line.
[0003] However, existing filters for lithium carbonate purification still present numerous inconveniences in practical applications. Traditional filters mostly use bolted flanges or clamps for connection. While the connections are secure, disassembly and installation are cumbersome, requiring specialized tools and time-consuming processes, leading to increased non-productive time and impacting overall production efficiency. Although some designs attempt to improve convenience by simplifying the cover connection structure, they fall short in terms of sealing reliability, structural strength, or operational ease. For example, some quick-connect designs may not provide uniform and sufficient clamping force to ensure effective compression of the sealing ring, posing a risk of leakage; while some filter element support structures are complex, requiring the disassembly of multiple components one by one when replacing the filter element, failing to truly achieve "quick disassembly." Furthermore, the lack of effective pressure relief and residual liquid drainage devices also increases the safety risks and complexity of maintenance operations.
[0004] Therefore, it is necessary to design a quick-release filter for lithium carbonate purification to solve the above-mentioned technical problems. Utility Model Content
[0005] In order to overcome the shortcomings of existing lithium carbonate purification filters, such as cumbersome disassembly and assembly, long time consumption, and the need for special tools that increase non-production time during filter element replacement, this utility model provides a lithium carbonate purification filter with a quick-release filter element.
[0006] The technical solution is as follows: A quick-release filter for lithium carbonate purification includes a support, a cylinder, a sealing cap, a handle, a feed pipe, locking blocks, and a sealing ring. The cylinder is fixedly connected to the top of the support, and the sealing cap is slidably connected to the top of the cylinder. The handle is fixedly connected to the middle of the top of the sealing cap, and the feed pipe is connected and communicated with the right side of the top of the sealing cap. Multiple locking blocks are fixedly connected in a ring array at the bottom of the sealing cap. Multiple locking slots are opened at corresponding positions on the top of the cylinder. The locking blocks and locking slots engage to position the sealing cap. A sealing ring is fixedly connected to the top edge of the cylinder. The filter also includes a ring magnet, a suction ring, a connecting seat, and bolts. The ring magnet is fixedly connected to the bottom of the cylinder. The suction ring has an annular groove at its bottom, and the suction ring slidably engages with the ring magnet through the annular groove. The connecting seat is fixedly connected to the top of the suction ring. The connecting seat has four mounting holes, and bolts are installed in each of the four mounting holes. The connecting seat is fixedly connected to the suction ring by the four bolts.
[0007] Furthermore, it also includes a filter element and a lifting rod. The filter element is fixedly connected to the top of the connecting seat, and the lifting rod is fixedly connected to the middle of the top of the filter element.
[0008] Furthermore, it also includes a drain pipe and a pressure relief valve. The drain pipe is connected to and connected to the bottom right side of the cylinder, and the pressure relief valve is fixedly connected to the top of the sealing cover.
[0009] Furthermore, a filter screen is installed at the bottom of the filter element.
[0010] Furthermore, the sealing ring is made of rubber.
[0011] Furthermore, the suction ring is made of magnetic material.
[0012] The beneficial effects are: 1. This utility model achieves the effect of positioning and supporting the filter element assembly by setting an annular magnet and a magnetic suction ring at the bottom of the cylinder, and then fixing the filter element through a connecting seat and bolts. With the setting of the lifting rod, it is easy to remove the filter element together with its supporting structure.
[0013] 2. This utility model achieves the effect of simplifying the filter element replacement process and shortening downtime by setting a ring array of locking blocks and slots on the top of the cylinder and using a handle to operate the installation and removal of the sealing cover.
[0014] 3. This utility model achieves the effect of releasing the internal pressure of the cylinder before disassembly and ensuring operational safety by setting a pressure relief valve on the sealing cover, and achieving the effect of draining residual liquid in the cylinder for easy cleaning and maintenance by setting a drain pipe.

Detailed Implementation
[0022] Example: A filter for lithium carbonate purification with a quick-release filter element, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a bracket 1, a cylinder 2, a sealing cap 3, a handle 4, a feed pipe 5, locking blocks 7, and a sealing ring 8. The top of the bracket 1 is connected to the cylinder 2 by screws. The sealing cap 3 is slidably connected to the top of the cylinder 2. The handle 4 is connected to the middle of the top of the sealing cap 3 by screws. The feed pipe 5 is connected and communicates with the right side of the top of the sealing cap 3. Multiple locking blocks 7 are connected to the bottom of the sealing cap 3 in a circular array by screws. Multiple slots 6 are opened at corresponding positions on the top of the cylinder 2. The locking blocks 7 and the slots 6 engage to position the sealing cap 3. The top edge of the cylinder 2 is connected by screws. The device includes a sealing ring 8 made of rubber, an annular magnet 9, a suction ring 10, a connecting seat 12, and bolts 14. The annular magnet 9 is connected to the bottom of the inner part of the cylinder 2 by screws. The bottom of the suction ring 10 has an annular groove 11, and the suction ring 10 is slidably engaged with the annular magnet 9 through the annular groove 11. The suction ring 10 is made of magnetic material. The top of the suction ring 10 is connected to the connecting seat 12 by screws. The connecting seat 12 has four mounting holes 13, and each of the four mounting holes 13 is provided with a bolt 14. The connecting seat 12 is fixedly connected to the suction ring 10 by the four bolts 14.
[0023] like Figure 5 and Figure 6As shown, it also includes a filter element 15, a lifting rod 16, a drain pipe 17, and a pressure relief valve 18. The top of the connecting seat 12 is connected to the filter element 15 by screws. The bottom of the filter element 15 is provided with a filter screen. The top middle of the filter element 15 is connected to the lifting rod 16 by screws. The bottom right side of the cylinder 2 is connected to and communicates with the drain pipe 17. The top of the sealing cover 3 is connected to the pressure relief valve 18 by screws.
[0024] When this device is needed, first, the bracket 1 is firmly placed in the predetermined position. The operator holds the handle 4 and aligns the sealing cover 3 with the top opening of the cylinder 2. With the guidance and cooperation of the locking block 7 and the locking groove 6, the sealing cover 3 is accurately positioned and pressed onto the cylinder 2. At this time, the sealing ring 8 at the top edge of the cylinder 2 is compressed, forming a preliminary sealing environment. The annular magnet 9 inside the cylinder 2 uses magnetic force to stably attract and fix the magnetic ring 10 to the bottom. The magnetic ring 10 is engaged with the annular magnet 9 through the annular groove 11 at its bottom. The connecting seat 12 is firmly connected to the top of the magnetic ring 10 with four bolts 14. The bottom of the filter element 15 is fixedly connected to the connecting seat 12. Its own filter screen structure is used to intercept impurities. The lifting rod 16 is fixed to the top center of the filter element 15 to provide a point of leverage for subsequent disassembly. When the sealing cover 3 is fully in place, the entire fluid channel is closed.
[0025] Once the device is ready, the lithium carbonate solution containing impurities is fed into the cylinder 2 through the feed pipe 5. Under pressure, the solution flows through the filter element 15, where insoluble particles and tiny impurities are trapped. The purified solution flows out from inside the filter element 15 and is collected through the bottom channel of the cylinder 2. The residual liquid in the cylinder 2 can be discharged or cleaned by opening the valve on the drain pipe 17. If the pressure inside the cylinder 2 rises abnormally during the filtration process, the pressure relief valve 18 on the top of the sealing cover 3 can be opened automatically or manually to release the pressure in time and ensure safe operation.
[0026] When filter element 15 becomes clogged due to impurities or reaches its replacement cycle, it needs to be replaced. First, confirm that there is no pressure inside the cylinder 2 through the pressure relief valve 18. Then, hold the handle 4, overcome the clamping force between the locking block 7 and the slot 6, and remove the sealing cover 3 from the cylinder 2. Next, hold the lifting rod 16 and lift the filter element 15, along with its bottom connecting seat 12 and suction ring 10 as a whole, vertically upward from the annular magnet 9 to complete the separation. When installing the new component, first, fix the suction ring 10 of the new component to the annular magnet 9 through the annular groove 11. Then, align the sealing cover 3 with the cylinder 2, press down and rotate it so that the locking block 7 is fully embedded in the slot 6, ensuring that the sealing ring 8 is fully compressed. Finally, check the reliability of all connections to complete the replacement of filter element 15 and restore the filtration function.
