[0002] An alkaline electrolytic cell is composed of a plurality of single-plate electrodes connected in series. The electrolytic cell is assembled, and the single-plate electrodes are pressed and locked by an external load. When a single-plate electrode fails, it needs to be replaced. It is necessary to separate the faulty electrode plate from the electrode plates on both sides to achieve the replacement of the faulty electrode plate. For a traditional electrolytic cell connected by tightening bolts, the electrolytic cell needs to be disassembled to complete the replacement of the faulty electrode plate. The workload of replacing a single-plate electrode is large, it is not easy to replace, and the maintenance cycle is long. When maintaining a single faulty electrode plate of a square hydraulic pressing type alkaline electrolytic cell, it is necessary to manually calibrate the position of the faulty electrode plate, install tooling blocks on the electrode plates on both sides of the faulty electrode plate, and complete the separation by traction with a steel wire rope or a chain and under the drive of a hydraulic cylinder. The efficiency of manually calibrating the faulty electrode plate is low, and the error rate is high. The installation of the chain is time-consuming, seriously affecting the maintenance efficiency of the electrode plate. At present, there is an urgent need to develop an efficient and reliable separation mechanism for separating faulty electrode plates of square electrolytic cells to reduce the parking time of the electrolytic cell due to the maintenance of electrode plate faults.

[0041] As Figure 1-8 shown, the present invention provides an electrolytic single-piece separation device, including:

[0042] A limiting mechanism, which includes a fixed end plate 1 and a movable end plate 2 respectively connected to the front and rear sides in the thickness direction of the electrolytic cell 3, and a pair of longitudinal beams 4 symmetrically arranged on the left and right sides in the horizontal direction of the electrolytic cell 3.

The front end of each outer tie rod 9 on each side passes through the outer side of the fixed-end tie rod arm 5 and is slidably connected to the fixed-end tie rod arm 5, and the rear end is fixedly connected to the outer side of the movable-end tie rod arm 6;

[0045] Separation arm mechanism, which includes a pair of inner separation arms 10 and a pair of outer separation arms 11 symmetrically arranged outward on the left and right sides of the electrolytic cell 3 in sequence, and is used to connect to the plates on the front and rear sides of the faulty plate 13. Each inner separation arm 10 on each side is slidably connected to the inner tie rod 8 and can slide axially relative to it. Each outer separation arm 11 on each side is slidably connected to the outer tie rod 9 and can slide axially relative to it. A locking mechanism 12 for temporarily locking the position of the corresponding inner separation arm 10 or outer separation arm 11 is also provided between the inner separation arm 10 and the inner tie rod 8, and between the outer separation arm 11 and the outer tie rod 9.

[0046] For the convenience of description, Figure 3 the right side is the front end and the left side is the rear end, Figure 3The vertical drawing direction is the left and right sides of the electrolytic cell 3, which is also horizontal. The left and right side directions are vertical. The limiting mechanism is mainly used to limit the left and right sides of the electrolytic cell 3 and connect the front and back sides, so as to drive the movement of some structures of the electrolytic cell 3 subsequently and achieve the purpose of rapid separation. The driving mechanism 7 is connected to the movable end plate 2 to drive the movable end plate 2 to move. The outer pull rod 9 in the pull rod mechanism moves synchronously with the movable end plate 2. The inner pull rod 8 is fixedly connected to the fixed end plate 1, so that the outer pull rod 9 can drive the outer separation arm 11 to move longitudinally, while the inner separation arm 10 moves longitudinally on the inner pull rod 8. After moving to the required position, the positions of the inner separation arm 10 and the outer separation arm 11 are temporarily fixed through the corresponding locking mechanisms 12 respectively, so that a pair of inner separation arms 10 and a pair of outer separation arms 11 are respectively located on the left and right sides of the front and back adjacent two plates of the faulty plate 13. Then, the inner separation arm 10 is connected to the left and right sides of the plate in front of the faulty plate 13, and the outer separation arm 11 is connected to the left and right sides of the plate behind the faulty plate 13 to prepare for separating the faulty plate 13; driven by the driving mechanism 7, the movable end plate 2, the outer pull rod 9, and the outer separation arm 11 are pulled backward to drive the plate adjacent to the rear side of the faulty plate 13 to move backward, and a vacancy is formed at the rear side of the faulty plate 13. At the same time, the plate adjacent to the front side of the faulty plate 13 is connected to the inner separation arm 10. Through the connection between the inner pull rod 8 and the fixed end plate 1 and the locking effect of the locking mechanism 12, the fixed end pull rod arm 5 does not generate displacement. Then, the locking mechanism 12 corresponding to the inner separation arm 10 is released, and the inner separation arm 10 is driven to push the faulty plate 13 backward by the plate adjacent to the front side of the faulty plate 13, and then reset, leaving the faulty plate 13 alone in the vacancy, realizing the separation of the faulty plate 13 from other plates, and further the maintenance of the faulty plate 13 can be completed.

[0047] The electrolytic single-piece separation device of the present invention includes a limiting mechanism, a pull rod mechanism, a driving mechanism 7, and a separation arm mechanism. The limiting mechanism is used to limit the left and right sides of the electrolytic cell 3 and connect the front and back sides. The pull rod mechanism is fixedly connected or slidably connected to the limiting mechanism. The separation arm mechanism is installed on the pull rod mechanism. The driving mechanism 7 is used to drive the movable end plate 2, the movable end pull rod arm 6, and the outer pull rod 9 to move. According to the separation requirements, select the locking states of the locking mechanisms 12 corresponding to the inner separation arm 10 and the outer separation arm 11, and select the connection states of the inner separation arm 10 and the outer separation arm 11 with the plates on the front and back sides of the faulty plate 13. Driven by the power of the driving mechanism 7, the inner separation arm 10 or the outer separation arm 11 is quickly moved to efficiently and accurately locate the position of the faulty plate 13, realize the rapid separation and maintenance of the faulty plate 13, is applicable to all square pressure filter type electrolytic cells 3, is not limited by the working medium, can efficiently and accurately complete the separation of the faulty plate 13, and has broad application prospects.

[0048] In another technical solution, such as Figure 1-8As shown, the inner separation arm 10 and the outer separation arm 11 are respectively C-shaped structures facing the electrolytic cell 3, including an upper section, a middle section, and a lower section. The upper section is inclined upward and outward, the lower section is inclined downward and outward, the middle section is sleeved and slidably connected to the corresponding inner pull rod 8 or the outer pull rod 9, the locking mechanism 12 is arranged in the middle section, and tooling blocks 14 are detachably connected to the top of the upper section and the bottom of the lower section respectively. The tooling blocks 14 are used to connect to the corresponding side positions of the electrodes of the electrolytic cell 3.

[0049] The tooling blocks 14 are arranged at the upper and lower sections respectively for connecting to the upper and lower ends of the left and right sides of the electrode plate to ensure balanced and stable movement of the electrode plate. The middle section is provided to facilitate sleeving on the corresponding inner pull rod 8 or outer pull rod 9 and to facilitate the installation of the locking mechanism 12.

[0050] In another technical solution, as Figure 1 , 3 -8 shows, threaded holes are respectively arranged at the upper and lower ends of the left and right sides of the electrode plate frame. At the top of the upper section and the bottom of the lower section, pin holes are respectively drilled through along the same axis of the threaded holes at the corresponding ends. The tooling block 14 includes connecting bolts inserted into the pin holes. Two connecting bolts at the same height are respectively inserted into the threaded holes on the normal electrode plate frames on the front and rear sides of the faulty electrode plate 13, and are fastened by screwing nuts on the other side of the pin holes. After the connecting bolts pass through the threaded holes and the pin holes and are screwed with nuts for fastening connection, the installation and disassembly are convenient, realizing the quick connection between the separation arm mechanism and the electrode plate at the required position.

[0051] In another technical solution, as Figure 1-8 shows, the fixed-end pull rod arms 5 are respectively arranged as vertical T-shaped structures, including a vertical part facing the electrolytic cell 3 and a horizontal part facing away from the electrolytic cell 3. The upper and lower ends of the vertical part extend away from the horizontal part and are respectively connected to the corresponding fixed-end plates 1, and a fixing cavity for fixing the longitudinal beam 4 is formed between the vertical part and the fixed-end plates 1. The front ends of the inner pull rod 8 and the outer pull rod 9 are respectively inserted or fixedly connected to the horizontal part.

[0052] Installation holes are transversely opened at the corresponding positions at the front end of the longitudinal beam 4. Screws are symmetrically arranged transversely at the upper and lower ends of the vertical part within the height range of the fixing cavity. After the screws pass through the installation holes on the longitudinal beam 4, they are threadedly connected and fixed to the fixed-end plates 1. The horizontal part is used to install the pull rod mechanism. The overall structure is exquisitely designed, occupies less space, and the installation connection is simple and firm.

[0053] In another technical solution, as Figure 1 , 3As shown in Fig. -8, a cross beam 15 is fixedly connected between a pair of the longitudinal beams 4 on both sides at the rear side of the movable end plate 2. A rod hole is formed in the middle of the cross beam 15. The driving mechanism 7 is a hydraulic cylinder arranged at the rear end of the cross beam 15. The piston rod 17 of the hydraulic cylinder passes through the rod hole and is connected to the movable end plate 2. The movable end plate 2 is driven to move by the telescopic movement of the piston rod 17 of the hydraulic cylinder.

[0054] In another technical solution, as Figure 1 、 3 shown in Fig. -8, supporting feet 18 are symmetrically arranged at the bottom of the cross beam 15 and at the bottom of the fixed end plate 1 to better adapt to the height position of the electrode plate of the electrolytic cell 3.

[0055] In another technical solution, as Figure 1-8 shown in the figure, the locking mechanism 12 includes tooth grooves 19 arranged along the length direction at the bottoms of the inner pull rod 8 and the outer pull rod 9 respectively. The arrangement length of the tooth grooves 19, a mounting groove 20 is vertically opened directly below the tooth grooves 19 in the middle section. The mounting groove 20 penetrates through the middle section on the side facing away from the electrolytic cell 3. A spring seat is fixed in the mounting groove 20. A spring is connected upward to the top surface of the spring seat. The top of the spring is connected upward to a locking pin. The locking pin is arranged in cooperation with the tooth grooves 19 to insert into the tooth grooves 19 to achieve card positioning. The top of the locking pin is connected downward to an L-shaped pin rod 21. The pin rod 21 sequentially passes through the inside of the spring and the middle of the spring seat downward and then extends to the outside of the middle section on the side facing away from the electrolytic cell 3. The distance between the bottom of the pin rod 21 and the bottom of the mounting groove 20 forms a vertical adjustment height, and the vertical adjustment height is greater than the depth of the tooth grooves 19.

[0056] The locking pin is arranged in cooperation with the inner shape of the tooth grooves 19. If the locking pin is upwardly inserted into one of the tooth grooves 19, the locking pin is limited by the tooth grooves 19 and cannot move longitudinally, thus locking the positions of the corresponding inner separating arm 10 and outer separating arm 11, positioning at the front and rear sides of the faulty electrode plate 13, and facilitating subsequent connection with the electrode plate.

[0057] In another technical solution, as Figure 1 、 3 shown in Fig. -8, clamping plates 16 are respectively connected vertically at the rear side of the fixed end plate 1 and the front side of the movable end plate 2. The front and rear clamping plates 16 are used for connecting with the corresponding sides of the electrolytic cell 3. The thickness of the clamping plates 16 is not less than the widths of the inner separating arm 10 and the outer separating arm 11 in the thickness direction of the electrolytic cell 3. The arrangement of the clamping plates 16 facilitates abutting against and connecting with the corresponding side surfaces of the electrolytic cell 3. At the same time, when pressing the electrolytic cell 3 to restore the state of the electrolytic cell 3, the inner separating arm 10 and the outer separating arm 11 can be respectively moved back to the positions of the clamping plates 16 to avoid interference with the subsequent installation and restoration of the electrolytic cell 3.

[0058] Combined withFigure 1-8 As shown, the present invention also provides a method for using an electrolytic single-piece separation device, including the following steps:

[0059] S1. As Figure 3 shown, the rear end of the fixed end plate 1 is fixedly connected to the front side of the electrolytic cell 3, and the movable end plate 2 is tightly attached to the rear side of the electrolytic cell 3 through the driving mechanism 7.

[0060] S2. As Figure 4 shown, move the inner separation arm 10 on the inner pull rod 8 and move the outer separation arm 11 on the outer pull rod 9, so that a pair of the inner separation arms 10 and a pair of the outer separation arms 11 respectively move to the faulty plate 13. After positioning by the locking mechanism 12, connect to the plates on the front and rear sides adjacent to the faulty plate 13.

[0061] Specifically, by directly moving the separation arm mechanism or driving through the corresponding outer pull rod 9, the inner separation arm 10 and the outer separation arm 11 are respectively moved to the required specified positions. The locking pin is upwardly inserted into one of the tooth grooves 19 to limit the separation arm mechanism and prevent it from moving longitudinally. Then, the tooling block 14 provided is adaptively connected to the bolt hole on the plate.

[0062] S3. As Figure 5 shown, start the driving mechanism 7 to drive the outer separation arm 11 to move backward to form a separation space and separate the plates.

[0063] S4. As Figure 6 shown, a pair of the inner separation arms 10 push the faulty plate 13 backward into the separation space, and then return forward to the position of step S3.

[0064] Specifically, the inner separation arm 10 is connected to the plate in front of the faulty plate 13, and the outer separation arm 11 is connected to the plate behind the faulty plate 13. The faulty plate 13 is in a free state and is only pushed by the plates on the front and rear sides, and is pushed and isolated into the separation space, facilitating the replacement of the faulty plate 13.

[0065] S5. As Figure 6 shown, take out the faulty plate 13 and put in a new plate.

[0066] S6. As Figure 7 shown, start the driving mechanism 7 to drive the movable end plate 2 to press the electrolytic cell 3.

[0067] S7. As Figure 8 shown, release the connection between the inner separation arm 10, the outer separation arm 11 and the plates in step S2, and reset to return to the initial position of step S1.

[0068] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those skilled in the art, additional modifications can be easily made.
