[0016] The present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.
[0017] like Figure 1 、 Figure 2 、 Figure 3 As shown, an electrolyte filtration device includes: a filter cylinder 1, a filter element 2 is arranged in the filter cylinder 1, and an electrolyte input pipe 3 with an input control valve 31 is connected to the inside of the filter element 2. The filter cylinder 1 includes an upper cylinder 11 and a lower cylinder 12, and the lower cylinder 12 is fixed on the base 120. An electrolyte output pipe 4 with an output control valve 41 is connected to the lower cylinder 12. A flange cylinder 5 is sealed and fixed on the outer wall of the upper end of the lower cylinder 12. The bottom of the filter element 2 is fixedly supported in the lower cylinder 12. The upper cylinder 11 is connected to the lifting drive mechanism, and the lifting drive mechanism can drive the upper cylinder 11 to move upward until the bottom of the upper cylinder 11 is higher than the top of the filter element 2 or can drive the upper cylinder 11 to move downward until it is supported on the flange cylinder 5. In this embodiment, the structure of the lifting drive mechanism includes: a lifting bracket 111 is provided on the outer wall of the upper cylinder 11. Said lifting bracket 111 is connected to the piston rod 1121 of the electric cylinder 112. When the piston rod 1121 of the electric cylinder 112 retracts upward, the upper cylinder 11 moves upward. When the piston rod 1121 of the electric cylinder 112 extends downward, the upper cylinder 11 moves downward. When the bottom of the upper cylinder 11 is higher than the top of the filter element 2, the filter element 2 can be replaced. In this embodiment, the upper cylinder 11 is driven by the lifting drive mechanism to move, effectively reducing labor and greatly facilitating the replacement of the filter element 2.
[0018] A clamp 6 is provided on the filter cylinder 1 in the area where the flange cylinder 5 is located. The clamp 6 includes: a clamp pin 63, a first clamp arm 61 and a second clamp arm 62 of a half structure hingedly connected to the clamp pin 63, and a first connecting block 611 and a second connecting block 621 are provided at the free ends of the first clamp arm 61 and the second clamp arm 62, respectively. The first connecting block 611 and the second connecting block 621 both include a connecting block body 60, and the connecting block body 60 is provided with a connecting groove 601 opening to the outside, and the screw 7 is passed through the connecting grooves 601 of the two connecting block bodies 60. One end of the screw 7 is hinged to the first connecting block 611, and a locking sleeve 71 is threadedly connected to the screw 7 outside the second connecting block 621. When the screw 7 is completely disengaged from the locking sleeve 71, the screw 7 can be rotated outward from the connecting groove 601. The locking sleeve 71 is driven by a rotary drive mechanism. The rotary drive mechanism can drive the locking sleeve 71 to move on the screw rod 7 toward the first connecting block 611 until the second connecting block 621 is driven to be tightly against the first connecting block 611, thereby making the first clamp arm 61 and the second clamp arm 62 tightly clamped on the outer walls of the upper and lower cylinders, or drive the locking sleeve 71 to move on the screw rod 7 away from the first connecting block 611 until the first clamp arm 61 and the second clamp arm 62 are loosened from the outer walls of the upper and lower cylinders.
[0019] In this embodiment, the structure of the rotary drive mechanism includes: a rotary drive motor 72, the piston rod of the rotary drive motor 72 being fixedly connected to the locking sleeve 71, and a roller 73 disposed at the bottom of the rotary drive motor 72. The roller 73 is disposed in a guide rail 74, and the roller 73 can drive the rotary drive motor 72 to rotate within the guide rail and move back and forth within the guide rail. The rotary drive motor 72 can drive the locking sleeve 71 to rotate in the forward or reverse direction, thereby driving the locking sleeve 71 on the screw rod 7 toward or away from the first connecting block 611. The connecting groove 601 ensures that when the second connecting block 621 abuts against or disengages from the first connecting block 611, the connecting groove 601 has a margin for the screw rod 7 to deflect therein. In this embodiment, the bottom of the rotary drive motor 72 is set in the guide rail 74 through the roller 73. Its purpose is: when the second connecting block 621 is blocked by the first connecting block 611 or disengaged from the first connecting block 611, the rotary drive motor 72 rotates accordingly to cooperate with the screw 7 and the locking sleeve 71 to deflect by a certain angle.
[0020] In this embodiment, a gas phase pipe 101 and a pressure transmitter 104 are provided at the top of the upper cylinder 11. The gas phase pipe 101 is connected to a gas phase vent branch pipe 102 and a nitrogen delivery pipe 103. A gas phase pipe control valve 1011 is provided on the gas phase pipe 101, and a vent branch pipe control valve 1021 is provided on the gas phase vent branch pipe 102. The gas phase vent branch pipe 102 is connected to the vent main pipe 8. The nitrogen delivery pipe 103 is provided with a nitrogen delivery control valve 1031.
[0021] The electrolyte input pipe 3 is connected to a first bottom drain 301 with a first drain control valve 3011, and the electrolyte output pipe 4 is provided with a second bottom drain 401 with a second drain control valve 4011. The first bottom drain 301 and the second bottom drain 401 are both connected to a waste liquid recovery pipe 91, which is connected to a waste liquid storage tank 9. The waste liquid recovery pipe 91 is provided with a waste liquid flowmeter 911 and a waste liquid recovery pipe control valve 912. The waste liquid storage tank 9 is provided with a tank gas phase discharge pipe 92 with a tank gas phase discharge control valve 921 and a manual discharge control valve 922. The tank gas phase discharge pipe 92 is connected to the vent main pipe 8.
[0022] An inner support ring 51 and an outer support ring 52 are respectively provided on the inner and outer walls of the flange cylinder 5. The inner support ring 51 and the flange cylinder 5 below the inner support ring 51 are welded and sealed to the upper end of the lower cylinder 12. The lower end of the upper cylinder 11 is supported on the inner support ring 51. The first clamp arm 61 and the second clamp arm 62 support and block the top of the flange cylinder 5 and the outer support ring 52. The provision of the outer support ring 52 plays a good supporting role. At the same time, the first clamp arm 61 and the second clamp arm 62 support and block the top of the flange cylinder 5 and the outer support ring 52, which can play a good guiding and positioning role. Two sealing rings 501 are spaced apart on the inner wall of the flange cylinder 5 above the inner support ring 51. The sealing rings 501 are sealed with the outer wall of the upper cylinder 11.
[0023] The working principle is as follows: when the filter element 2 needs to be replaced, close the input control valve 31 and the output control valve 41, open the gas phase pipe control valve 1011, and open the first drain control valve 3011, the second drain control valve 4011, the waste liquid recovery pipe control valve 912, the storage tank gas phase discharge control valve 921 and the manual discharge control valve 922.
[0024] Then the nitrogen delivery control valve 1031 is opened, and nitrogen enters the filter cylinder 1 through the nitrogen delivery pipe 103 for pressurized discharge. The electrolyte in the electrolyte input pipe 3 and the residual electrolyte in the filter cylinder 1 will flow from the waste liquid recovery pipe 91 into the waste liquid storage tank 9 through the first bottom drain 301 and the second bottom drain 401 respectively. When the waste liquid flow meter 911 shows a flow rate of zero, it means that the residual electrolyte has been discharged. After a delay of 10S, the nitrogen delivery control valve 1031, the waste liquid recovery pipe control valve 912, and the tank gas phase discharge control valve 921 are closed. Then, the vent branch pipe control valve 1021 is opened. When the pressure detected by the pressure transmitter is ≤0.01Mpa, the vent branch pipe control valve 1021 is closed. Next, the nitrogen delivery control valve 1031 is opened, and the pressure in the filter cylinder 1 is continuously increased to 0.1 MPa. Then, the nitrogen delivery control valve 1031 is closed, and the vent branch control valve 1021 is opened. When the pressure detected by the pressure transmitter is ≤ 0.01 MPa, the vent branch control valve 1021 is closed. This step is repeated three times.
[0025] Afterwards, the rotary drive mechanism drives the locking sleeve 71 on the screw 7 to move away from the first connecting block 611 until the first clamp arm 61 and the second clamp arm 62 are loosened from the outer walls of the upper and lower cylinders. Then the piston rod 1121 of the electric cylinder 112 retracts upward to drive the upper cylinder 11 to move upward until the bottom of the upper cylinder 11 is higher than the top of the filter element 2, so that the filter element 2 can be replaced.
[0026] After the filter element 2 is replaced, the piston rod 1121 of the electric cylinder 112 extends downward, driving the upper cylinder 11 downward until the bottom of the upper cylinder 11 moves downward and is supported on the flange cylinder 5. The rotary drive mechanism then drives the locking sleeve 71 on the screw 7 toward the first connecting block 611 until the second connecting block 621 is tightly against the first connecting block 611, thereby tightly clamping the first clamp arm 61 and the second clamp arm 62 to the outer walls of the upper and lower cylinders. The nitrogen delivery control valve 1031 is then opened, pressurizing the filter cylinder 1 to 0.1 MPa. The nitrogen delivery control valve 1031 is then closed, and the vent branch control valve 1021 is opened. When the pressure detected by the pressure transmitter is ≤0.01 MPa, the vent branch control valve 1021 is closed. This step is repeated twice. After waiting for 2 to 3 minutes, check whether the pressure change is less than or equal to 0.005Mpa. If the requirement is met, the filter element replacement work of the entire electrolyte filtration device is completed and the electrolyte filtration work can be carried out again.
[0027] In this embodiment, the vent branch control valve 102, the nitrogen delivery control valve 1031, the tank gas phase discharge control valve 921, the waste liquid flow meter 911, the waste liquid recovery pipe control valve 912, the electric cylinder 112, and the rotary drive motor 72 all communicate with the PLC controller 100, which can greatly improve the degree of automation of the entire electrolyte filtration device.
[0028] As can be seen from the above, the utility model provides an electrolyte filtration device with a simple structure, which basically realizes the automation of the replacement of the filter element 2, providing great convenience for the replacement of the filter element 2. The nitrogen pressurization method can ensure that the electrolyte can be completely recovered into the waste liquid storage tank 9 during the replacement of the filter element 2. The electrolyte in the waste liquid storage tank 9 is collected centrally, reducing the waste electrolyte residue and tail gas residue during the filter element replacement process, meeting environmental protection requirements. After the filter element is replaced, the nitrogen replacement effectively ensures that the air in the filter cylinder is exhausted, thereby ensuring the stable quality of the filtration product.
