Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production equipment, in particular to a lithium battery slurry conveying pipeline cleaning and recovery system. Background Art

[0002] The production process of lithium batteries involves the transportation of lithium battery cell slurry. Due to the high viscosity and solid content of lithium battery cell slurry, the slurry is prone to sedimentation and drying in the transportation pipeline during long-term transportation, which makes the transportation pipeline face problems such as blockage and scaling. The transportation pipeline needs to be cleaned and unblocked regularly. The existing lithium battery cell slurry transportation pipeline generally uses a cleaning ball through a ball pushing device to achieve regular cleaning and unblocking of the inner wall of the pipeline.

[0003] The existing technical solution is to equip the end of the pipeline with a pressure relief vehicle to release the pipeline pressure and receive the residual slurry from the pressure relief vehicle. However, the capacity of the pressure relief vehicle is limited, and the internal slurry needs to be cleaned manually regularly. If the personnel fail to clean the internal slurry in time, the ball pushing pressure has nowhere to be released, which will cause the slurry to overflow and splash onto the human body, posing a great safety hazard.

[0008] A further improvement is that the plurality of cleaning ball sensors include a first cleaning ball sensor, a second cleaning ball sensor, a third cleaning ball sensor, a fourth cleaning ball sensor, and a fifth cleaning ball sensor, and the first cleaning ball sensor, the second cleaning ball sensor, the third cleaning ball sensor, the fourth cleaning ball sensor, and the fifth cleaning ball sensor are sequentially arranged on the conveying main pipe between the ball inlet and the ball retrieval cage.

[0009] A further improvement is that the inlet end of the coating buffer tank is connected to the conveying main pipe between the first cleaning ball sensor and the second cleaning ball sensor through a three-way valve, and an eighth pneumatic valve is provided between the coating buffer tank and the conveying main pipe.

[0010] Further improvements are: the inlet end of the first transfer tank is connected to the delivery main pipe between the third cleaning ball sensor and the fourth cleaning ball sensor through a three-way valve, and the outlet end of the first transfer tank is connected to the inlet end and the drain valve of the filter respectively through a three-way valve; a first pneumatic valve is arranged between the first transfer tank and the delivery main pipe, and a second pneumatic valve is arranged between the first transfer tank and the filter.

[0015] A further improvement is that a seventh pneumatic valve is provided between the filter and the iron remover.

[0016] Compared with the existing technology, the above technical solution has the following beneficial effects:

[0017] By eliminating the existing pressure relief vehicle and connecting the conveying main pipe to the front end of the screw pump, the pressure during the cleaning of the conveying main pipe and the residual slurry at the end can be released to the transfer tank, which not only ensures the safety of personnel, but also reduces costs and saves slurry.
