Description

Technical Field

[0001] This utility model relates to the technical field of lithium carbonate production equipment, and in particular to an anti-clogging device for lithium carbonate carbon dioxide pipelines. Background Technology

[0002] In the production process of lithium carbonate, carbon dioxide pipelines often face serious scaling and blockage problems. As carbon dioxide flows in the pipeline, it reacts chemically with the lithium hydroxide solution. At the same time, it is affected by factors such as temperature, pressure and flow rate, which easily form a hard scale layer on the inner wall of the pipeline.

[0003] As operating time increases, scale buildup leads to reduced pipe diameter, obstructed gas flow, and even complete blockage, affecting production continuity. Frequent scaling in the pipes makes cleaning a challenging task. Current cleaning methods often require manual disassembly of the pipes, using small-diameter stainless steel pipes for unblocking, or chemical flushing. This high frequency of cleaning places a significant strain on employees' workload.

[0004] In addition, foreign objects can easily be introduced during the cleaning process. For example, metal shavings, dust or other impurities may enter the piping system when disassembling and reinstalling pipes. Once these foreign objects enter the production process, they can cause impurities in the product, thus affecting the product quality. Utility Model Content

[0016] This utility model proposes an anti-clogging device for a lithium carbonate carbon dioxide pipeline. When carbon dioxide is being transported normally, the airflow pressure pushes the anti-clogging cover to overcome the resistance of the reset component, so that the vent is in the open state. The gas diffuses evenly through the porous structure. The purging component starts before the gas supply stops, continuously inputting gas to form a flushing flow to prevent crystal deposition. When the gas completely stops, the reset component drives the anti-clogging cover to close the vent and block the solution backflow. Furthermore, before the carbon dioxide gas input needs to be stopped, the gas source component is turned on to introduce inert gas or compressed air, thereby isolating the solution from the outside of the entire pipeline. The pressure of the gas source component can also be gradually reduced in steps until the gas pressure is lower than that of the reset component. At this point, the anti-clogging cover slides and closes the vent. During this process, the solution is completely blocked from the outside of the pipeline, solving the problem of scaling and pipe blockage that is easy to occur in the carbon dioxide management of existing lithium carbonate production equipment. In addition, the purging airflow continuously maintains the cleanliness of the pipeline, and the automatic opening and closing function of the anti-clogging component prevents the solution from backflowing and crystallizing. The dual protection mechanism significantly extends the continuous operation cycle of the pipeline and realizes the self-maintenance function of the carbon dioxide delivery system in the lithium carbonate production process.

[0024] Example 1: Please refer to the attached document as well. Figures 1 to 7 This embodiment provides an anti-clogging device for a lithium carbonate carbon dioxide pipeline 2. The device is installed on the carbon dioxide pipeline 2 of the carbonization reactor 1, and the device includes: The purging assembly 3 has one end connected to the gas source assembly 4 and the other end connected to the carbon dioxide pipeline 2. An anti-clogging component 5 is disposed at the outlet end of the carbon dioxide pipeline 2 and together with it is placed inside the carbonization reactor 1. The anti-clogging component 5 includes an anti-clogging head 51, an anti-clogging cover 52, and a reset member 53. The anti-clogging head 51 is connected to the outlet end of the carbon dioxide pipeline 2. The end of the anti-clogging head 51 is provided with a plurality of vent holes 511. The reset member 53 is disposed inside the anti-clogging head 51 and is connected to the inner wall of the anti-clogging cover 52. The anti-clogging cover 52 is slidably disposed with respect to the end of the anti-clogging head 51 and is used to close the plurality of vent holes 511.

[0025] It should be noted that pipeline blockage mainly stems from solution backflow and crystal deposition after gas delivery stops. Based on fluid dynamics analysis, a method is proposed to utilize continuous airflow to flush the pipe wall during the gas delivery phase and to block solution contact with the pipeline during the shutdown phase. Specifically, when carbon dioxide is being delivered normally, the airflow pressure pushes the anti-blocking cover 52 to overcome the resistance of the reset element 53, opening the vent 511. Gas diffuses evenly through the porous structure. The purging assembly 3 is activated before the gas supply stops, continuously inputting gas to form a flushing flow, preventing crystal deposition. When the gas supply completely stops, the reset element 53 drives the anti-blocking cover 52 to close the vent 511, blocking solution backflow. More specifically, before the carbon dioxide gas input needs to be stopped, the gas source component 4 is turned on to introduce inert gas or compressed air, thereby isolating the solution from the outside of the entire pipeline. In addition, the pressure of the gas source component 4 can be slowly reduced in steps until the gas pressure is lower than that of the reset component 53. At this point, the anti-blocking cover 52 slides and closes the vent 511. During this process, the solution is completely blocked from the outside of the pipeline, solving the problem of scaling and pipe blockage that easily occurs in the carbon dioxide management of existing lithium carbonate production equipment. Furthermore, the purging airflow continuously maintains the cleanliness of the pipeline, and the automatic opening and closing function of the anti-blocking component 5 prevents the solution from backflowing and crystallizing. The dual protection mechanism significantly extends the continuous operation cycle of the pipeline and realizes the self-maintenance function of the carbon dioxide delivery system in the lithium carbonate production process.

[0026] In some embodiments, the purging assembly 3 is preferably a fluid delivery system connecting the gas source and the pipeline, specifically a pipeline system with control valves, used to maintain gas flow in the pipeline during non-production periods.

[0027] In some embodiments, the anti-blocking head 51 is preferably a structural component installed at the end of the pipeline, specifically made of corrosion-resistant metal material, and the vent holes 511 at its end can be designed as a ring array.

[0028] In some embodiments, the anti-blocking cover 52 is preferably a movable component covering the end of the anti-blocking head 51. Specifically, it can adopt a conical cover structure or a cylindrical structure that matches the anti-blocking head 51, and the opening and closing of the channel can be achieved through sliding fit.

[0029] In some embodiments, the reset member 53 is preferably a mechanical component that provides elastic restoring force, specifically a helical spring or an elastic rubber element, for driving the anti-blocking cover 52 to automatically reset.

[0030] Specifically, when carbon dioxide is being supplied normally, the airflow pressure pushes the anti-clogging cover 52 to overcome the resistance of the reset component 53, opening the vent 511 and allowing gas to diffuse evenly through the porous structure. The purging assembly 3 activates during gas supply interruptions, continuously supplying gas to form a flushing flow and prevent crystal deposition. When the gas supply completely stops, the reset component 53 drives the anti-clogging cover 52 to close the vent 511, blocking solution backflow. The porous structure design of the anti-clogging head 51 reduces the risk of single-hole blockage, and the elastic connection of the reset component 53 ensures the automatic reset function of the protective structure. The synergistic effect of the purging assembly 3 and the anti-clogging assembly 5 achieves continuous protection throughout the production cycle.

[0031] In this embodiment, the device further includes a sealing member 54. A sealing plate 512 is fixedly provided on the inner wall of the anti-blocking head 51. A plurality of sealing holes 513 are provided on the sealing plate 512. The sealing member 54 is disposed inside the anti-blocking head 51 and is connected to the reset member 53.

[0032] Understandably, when the carbon dioxide pipeline 2 is in a non-ventilated state, the preload of the return spring 531 pushes the sealing member 54 upward, so that the cylinder at the top of the sealing member 54 is fully inserted into the sealing hole 513, forming a physical isolation layer to physically seal the carbon dioxide pipeline 2.

[0033] In some embodiments, the sealing plate 512 is preferably an annular metal plate welded or bolted to the inner wall of the anti-blocking head 51.

[0034] In this embodiment, the upper end face of the sealing member 54 is provided with a plurality of sealing heads 541 that cooperate with the sealing hole 513.

[0035] When the purging assembly 3 is not activated, the sealing head 541 is embedded in the sealing hole 513 under the action of the reset member 53, forming a multi-point contact sealing interface to block external foreign objects from entering the pipeline through the sealing hole 513.

[0036] In some embodiments, the sealing head 541 is preferably a protruding structure provided on the top of the sealing member 54, which can be implemented by a conical or cylindrical metal block, and its outer diameter is interference-fitted with the inner diameter of the sealing hole 513; more preferably, its fit can also be a transition fit, and a better sealing effect can be achieved by providing a gasket or plastic layer on the outside of the sealing head 541.

[0037] In this embodiment, the reset member 53 includes a reset spring 531 and a reset rod 532. The reset spring 531 is sleeved on the outer periphery of the reset rod 532. The two ends of the reset spring 531 are respectively connected to the lower end face of the sealing member 54 and the upper end face of the inner wall of the anti-blocking head 51. One end of the reset rod 532 is connected to the lower end face of the sealing member 54, and the other end of the reset rod 532 moves through the lower end face of the anti-blocking head 51 and is connected to the upper end face of the anti-blocking cover 52.

[0038] When the purging airflow acts on the sealing member 54 through the sealing hole 513, the sealing member 54 compresses the return spring 531 downwards. At this time, the return rod 532 moves downwards synchronously with the sealing member 54, causing the anti-clogging cover 52 to disengage from the vent hole 511. After purging, the elastic restoring force of the return spring 531 gradually pushes the sealing member 54 upwards to reset. The rigid connection of the return rod 532 causes the anti-clogging cover 52 to move upwards synchronously to re-close the vent hole 511. The return spring 531 is sleeved on the outer circumference of the return rod 532, so that the compression direction of the spring is constrained by the axial direction of the rod body, preventing the sealing member 54 from tilting due to spring bending. The movable through-structure between the return rod 532 and the lower end face of the anti-clogging head 51, through the clearance fit between the rod body and the through hole, maintains the axial freedom of movement while limiting the radial swing amplitude of the return rod 532.

[0039] In some embodiments, the reset spring 531 is preferably an elastic element with axial compression characteristics, specifically a helical spring, with its two ends contacting the inner walls of the closure 54 and the anti-blocking head 51 respectively to form a bidirectional elastic support, which is used to provide the reset driving force for the closure 54 and the anti-blocking cover 52.

[0040] In some embodiments, the reset rod 532 is preferably a rod-shaped component with axial rigidity, specifically a stainless steel rod body, which penetrates the lower end face of the anti-blocking head 51 and is connected to the anti-blocking cover 52 to transfer the displacement of the sealing member 54 to the anti-blocking cover 52.

[0041] In some embodiments, the movable through-hole is preferably a structure that maintains an axial movement clearance between the rod and the through-hole, which can be achieved by using a sliding bearing or a guide sleeve to limit the radial offset of the reset rod 532 while allowing axial movement.

[0042] In this embodiment, the sealing member 54 includes a sealing cylinder 542, a sealing disc 543, and a plurality of sealing springs 544. The sealing cylinder 542 is movably disposed inside the anti-blocking head 51, the sealing disc 543 is fixedly connected to the lower part of the sealing cylinder 542, the plurality of sealing springs 544 are disposed on the outer periphery of the sealing disc 543, and the plurality of sealing heads 541 are disposed on the upper end face of the sealing disc 543.

[0043] Understandably, the sealing cylinder 542 is preferably a cylindrical structure that can move axially along the interior of the anti-blocking head 51, and can be made of stainless steel. Its outer surface forms a sliding fit with the inner wall of the anti-blocking head 51 to transmit displacement caused by pressure fluctuations. The sealing disc 543 is preferably a disc-shaped component fixedly connected to the lower end of the sealing cylinder 542, and can be welded to the sealing cylinder 542 to support the array of sealing heads 541 and maintain flatness. The sealing spring 544 is preferably an elastic element distributed around the outer edge of the sealing disc 543, and can be a helical spring structure. Its two ends are respectively connected to the inner wall of the sealing disc 543 and the anti-blocking head 51 to provide radial restraint force.

[0044] When the internal pressure of the carbon dioxide pipeline 2 increases, the sealing cylinder 542 slides upward along the inner wall of the anti-clogging head 51 under the thrust of the gas, causing the sealing disc 543 and the sealing head 541 to rise as a whole. At this time, the sealing spring 544 is compressed, generating a reverse force, which keeps the sealing head 541 in contact with the sealing hole 513. When the pressure decreases, the sealing spring 544 pushes the sealing disc 543 to reset, and the sealing head 541 continues to press against the sealing hole 513. The rigid support of the sealing disc 543 ensures that all sealing heads 541 move synchronously, avoiding local sealing failure due to uneven force. The radial arrangement of the sealing spring 544 allows the sealing disc 543 to deviate slightly during pressure fluctuations, while maintaining the stability of the sealing contact surface through preload.

[0045] In this embodiment, the inner wall of the anti-blocking head 51 is provided with a sliding groove 514, the sealing cylinder 542 is slidably disposed in the sliding groove 514, and the end of the sealing spring 544 is fixedly connected to the bottom of the sliding groove 514.

[0046] Understandably, after the end of the sealing spring 544 is fixed to the bottom of the slide groove 514, the compression and rebound process of the spring always proceeds along the axial direction of the slide groove 514, ensuring that the sealing cylinder 542 can accurately return to its initial position after the gas pressure disappears. When the gas pressure in the carbon dioxide pipeline 2 pushes the anti-clogging cover 52 to move, the sealing cylinder 542 slides along the slide groove 514 and compresses the sealing spring 544, and the sealing head 541 on the sealing disc 543 disengages from the sealing hole 513 to allow gas to pass through; when the pressure decreases, the elastic force of the sealing spring 544 drives the sealing cylinder 542 to slide in the opposite direction, and the sealing head 541 re-inserts into the sealing hole 513 to achieve a seal.

[0047] In this embodiment, a plurality of the vent holes 511 are evenly distributed at intervals on the outer peripheral surface of the anti-blocking head 51.

[0048] Understandably, when individual vents 511 become blocked, the remaining vents 511 can still maintain effective ventilation, ensuring the device's continuous operation under complex conditions.

[0049] In this embodiment, the end of the anti-blocking head 51 is provided with a thread, and the anti-blocking head 51 is detachably connected to the carbon dioxide pipeline 2 through the thread.

[0050] Traditional pipeline maintenance requires disassembling the entire pipe section or using flange connections, involving the tightening of multiple bolts and replacement of gaskets, which can easily lead to foreign object residue. Threaded connections, on the other hand, require only a single rotation to complete disassembly and assembly, and the operation does not involve the internal space of the pipe, significantly reducing the risk of foreign object intrusion. Furthermore, the standardized interface of the threaded connection allows the anti-clogging head 51 to be replaced as an independent module, eliminating the need for customized processing.

[0051] Example 2: In this embodiment, the carbon dioxide pipeline 2 includes a fixed part and several telescopic parts, and the several telescopic parts are sequentially spliced ​​together to form a telescopic rod and then installed inside the carbonization kettle 1.

[0052] In this embodiment, an improvement is made to the portion of the traditional fixed carbon dioxide pipeline 2 within the carbonization reactor 1, allowing it to contract upwards when no carbon dioxide gas is introduced, ultimately preventing it from being immersed in the solution. Specifically, a dynamic seal is preferably maintained between the various telescopic parts using structures such as plastic gaskets. When no carbon dioxide is introduced, the valve switches to the gas source assembly 4 to introduce inert gas or compressed air into the carbonization reactor 1. The pressure is then slowly reduced to decrease the tension on the return spring 531 until the restoring stress of the return spring 531 exceeds the pressure. The pressure is then further reduced to gradually close the vent hole 511 with the anti-clogging cover 52. After the gas source assembly 4 stops introducing gas, the anti-clogging cover 52 completely closes the vent hole 511. At this point, the gas source assembly 4 is switched to convert the jet rotation into a suction action. During this process, the pressure in the carbon dioxide pipeline 2 gradually decreases, forcing the telescopic parts to move upwards until the lowest telescopic part is no longer in contact with the solution.

[0053] It is understandable that the telescopic structure capable of achieving the above actions is relatively existing, such as telescopic fishing rods and other structures that are interlocked and can maintain a relatively sealed structure, which will not be elaborated here.

[0054] It is also understood that the telescopic part includes a telescopic inner cylinder and a telescopic outer cylinder, with the outer cylinder sleeved around the outer circumference of the inner cylinder. The diameter of the telescopic part decreases or increases from top to bottom, and the fixed part is fixedly connected to the upper end of the carbonization reactor 1. Through the nesting cooperation of the inner and outer cylinders, the length of the pipeline can be flexibly adjusted, ensuring that the gas outlet is always in the optimal working position, reducing the contact time between the gas and the pipe wall, and inhibiting the adhesion of lithium carbonate crystals. The axial sliding and sealing design of the nested structure maintains the continuity and tightness of gas delivery during adjustment, avoiding gas leakage or foreign object intrusion caused by length changes, thereby reducing the risk of pipeline blockage and improving production stability.

[0055] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
