[0002] In the recycling and processing of waste lithium batteries, the combustion furnace is one of the core pieces of equipment. The lithium batteries need to be pyrolyzed through the coordinated operation of different chambers inside the furnace.
[0003] The lifting valves of traditional combustion furnaces generally have the following problems:
[0004] First, the sealing structure is not reliable enough and is prone to leakage under high temperature conditions, which can cause cross-flow between the combustion chamber and the backflush chamber, affecting the recovery efficiency.
[0005] Secondly, the components have poor stability, and the seals are prone to shifting during long-term operation, causing equipment failure.
[0006] In the existing technology, although some lift valves have basic opening and closing functions, there is still room for improvement in terms of structural optimization, sealing performance improvement and adaptability to complex working conditions.
[0007] Therefore, there is an urgent need to design a lift valve with a novel structure, reliable sealing, and adaptability to the high-temperature environment of waste lithium battery recycling. Utility Model Content

[0028] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.
[0029] refer to Figure 1 , 2 3. Example 1: A lifting valve for processing waste lithium battery recycling equipment, including a combustion furnace 1, a fixing component 1 2, a fixing component 2 3, a sealing component 6, and a lifting assembly.
[0030] The combustion furnace 1 is provided with a combustion chamber 10 and a backflush chamber 11, and the combustion chamber 10 is provided with a through hole 12 communicating with the backflush chamber. The combustion chamber 10 is used for the combustion treatment of waste lithium batteries, and the backflush chamber 11 is used to provide backflush gas. The gas communication between the two chambers is achieved through the through hole 12.
[0031] Fixing component 2 is connected to the inner wall of the combustion chamber 10, and fixing component 3 is connected to the outer wall of the backflush chamber 11. Fixing component 2 and fixing component 3 are connected by a fixing rod 4. Fixing component 2 has a through hole 5 corresponding to the through hole 12. The fixing rod 4 serves to support and connect fixing component 2 and fixing component 3, maintaining a relatively stable positional relationship between them. The through hole 5 provides a channel for gas flow.
[0032] The sealing element 6 is movably disposed between the first fixing element 2 and the second fixing element 3, and is used to seal the through hole 5. The sealing element 6 can move along the axial direction of the fixing rod 4. When sealing is required, the sealing element 6 moves to cover the through hole 5, preventing gas flow; when backflushing is required, the sealing element 6 moves away from the through hole 5, allowing gas to flow through the through hole 5 between the combustion chamber 10 and the backflushing chamber 11. The second fixing element 3 is provided with a lifting assembly, which is used to move the sealing element 6, driving the sealing element 6 to move along the axial direction of the fixing rod 4.
[0033] The lifting assembly includes an auxiliary support 7 and a power assembly 8. The auxiliary support 7 is fixedly installed on the outer wall of the second fixing member 3 to support the power assembly 8, ensuring its stable installation on the second fixing member 3. The power assembly 8 is mounted on the auxiliary support 7, and its output end is fixedly connected to the rear end of the sealing member 6 via an auxiliary rod. The power assembly 8 provides power, which drives the sealing member 6 to move via the auxiliary rod, thus achieving the lifting and lowering of the sealing member 6.
[0034] The power assembly 8 includes any one of hydraulic, pneumatic, and electric telescopic rods. These telescopic rods have advantages such as simple structure, stable operation, and convenient control, and a suitable power assembly 8 can be selected according to actual needs.
[0035] The fixing member 2 is provided with an annular sealing hole 20, and the sealing member 6 has a sealing block 60 protruding from its end face facing the fixing member 2, which is adapted to the sealing hole. When the sealing member 6 moves to the sealing position, the sealing block 60 is inserted into the annular sealing hole 20 to form a tight seal and effectively prevent gas leakage.
[0036] The second fixing member 3 is provided with a receiving hole 30 corresponding to the sealing member 6. When the sealing member 6 is moved to a position away from the first fixing member 2, the sealing member 6 can be partially or completely stored in the receiving hole 30, avoiding the sealing member 6 from being exposed to the external environment and reducing the impact of dust and impurities on the sealing member 6.
[0037] The inner wall of the receiving hole 30 is provided with a buffer layer, which is made of elastic rubber material. The buffer layer can buffer the movement of the seal 6 into the receiving hole 30, reduce the collision and wear between the seal 6 and the inner wall of the receiving hole 30, and extend the service life of the seal 6.
[0038] The outer wall of the sealing block 60 is provided with several annular grooves, and a sealing ring is installed in the annular groove. The sealing ring can further improve the sealing effect between the sealing block 60 and the annular sealing hole 20, and prevent gas from leaking from the gap between the sealing block 60 and the annular sealing hole 20.
[0039] Working principle: When backflushing of the combustion chamber 10 is required, the power assembly 8 (hydraulic telescopic rod) extends, driving the seal 6 to move away from the fixed part 2 along the axial direction of the fixed rod 4 via the auxiliary rod 7. The sealing block 60 gradually exits from the annular sealing hole 20 until the seal 6 is partially housed in the receiving hole 30. At this time, the through hole 5 opens, and the backflushing gas in the backflushing chamber 11 enters the combustion chamber 10 through the through hole 12 and the through hole 5 to perform the backflushing operation. After the backflushing is completed, the power assembly 8 retracts, driving the seal 6 to move closer to the fixed part 2. The sealing block 60 is inserted into the annular sealing hole 20, and the sealing ring fits tightly with the annular sealing hole 20, achieving a seal on the through hole 5. During the movement of the seal 6, the buffer layer on the inner wall of the receiving hole 30 effectively buffers the collision between the seal 6 and the inner wall of the receiving hole 30, reducing wear.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
