Description

Technical Field

[0001] This invention relates to the field of chemical equipment, and in particular to a highly efficient and convenient descaling device and method for the inner wall of an electrolyte tank. Background Technology

[0002] Electrolyte is the medium used in chemical batteries and electrolytic capacitors. It is a commonly used raw material in the chemical industry and requires high purity in most applications. This places high demands on the cleanliness of electrolyte storage containers.

[0003] Electrolyte is usually stored in stainless steel electrolyte tanks. As a reusable container, the inner wall of the electrolyte tank needs to be thoroughly descaled and cleaned before each replacement (refilling) of the electrolyte to avoid contamination of the newly added electrolyte by residual impurities in the tank.

[0004] The structure of common electrolyte tanks is as follows: Figure 11 As shown, the electrolyte container includes a barrel body 61 and a lid 62. The barrel body 61 is cylindrical, with an opening 611 at the center of its upper end. The diameter of the opening 611 is only 1 / 5 to 1 / 3 of the inner diameter of the barrel body 61. The lid 62 is placed over the opening at the upper end of the barrel body 61. Because the diameter of the opening 611 at the upper end of the barrel body 61 is much smaller than the inner diameter of the barrel body 61, it is difficult to clean the inner wall of the barrel body 61 manually by inserting cleaning tools (such as a brush) through the opening 611. This will cause impurities and scale to easily accumulate on the inner wall of the electrolyte container 61. When the electrolyte is replaced (refilled), the impurities and scale remaining on the inner wall of the container will contaminate the electrolyte, resulting in the inability to guarantee the purity of the electrolyte.

[0018] The technical solution of the present invention is: a method for descaling the inner wall of an electrolyte tank, applied to the above-mentioned efficient and convenient descaling device for the inner wall of an electrolyte tank, used to remove dirt and impurities adhering to the inner wall of the electrolyte tank; the electrolyte tank includes a tank body and a tank lid; the tank body is cylindrical, with an opening at the center of its upper end; the tank lid is placed over the opening at the upper end of the tank body;

[0019] Before the descaling operation, the efficient and convenient descaling device for the inner wall of the electrolyte tank is in its initial state. In the initial state:

[0020] a. All pistons of cylinder A in the hopper positioning kit are in the retracted state;

[0021] b. The lifting frame is at the top of its travel range;

[0022] c. Rotate the brush head to a vertical position;

[0023] The descaling procedure is as follows:

[0024] S01, Loading the electrolyte tank: Remove the lid of the electrolyte tank to be descaled, place the tank body on the tank support surface at the bottom of the frame, and push it into the positioning ring of the tank positioning kit. At this time, the entire tank body is located in the tank receiving area at the bottom of the frame. Then, the pistons of all cylinders A in the tank positioning kit extend synchronously, causing the positioning ring to gradually shrink. Finally, all the positioning blocks in the tank positioning kit abut against the outer wall of the electrolyte tank, positioning the electrolyte tank body in the center area of ​​the tank receiving area. At this time, the brush head is located directly above the opening at the top of the tank body.

[0025] S02: Brush head inserted into the inner cavity of the barrel: Motor B starts, and motor B drives the lead screw to rotate through the reducer. The rotation of the lead screw drives the nut, lifting frame, brush head rotation control mechanism and brush head to move vertically downward in sync. When the brush head is fully inserted into the inner cavity of the barrel through the opening at the top of the barrel, motor B stops running.

[0026] S03: Brush head rotates to horizontal position: Cylinder B starts, the piston of cylinder B extends, driving the pull rod shaft to move vertically downward. The pull rod shaft drives the brush head to rotate around the sixth hinge of the J-shaped brush plate in the vertical plane through the connecting rod, so that the brush head rotates from the vertical position to the horizontal position. At this time, the bristles on the horizontal section of the J-shaped brush plate contact the uppermost end of the inner cavity side wall of the barrel.

[0027] S04, Descaling the inner wall of the tank:

[0028] a. When motor A starts, motor A drives the hollow shaft to rotate through the reducer. When the hollow shaft rotates, it drives the vertical rotating component and the brush head to rotate synchronously on the horizontal plane.

[0029] b. Motor B starts and drives the lead screw to rotate through the reducer. The rotation of the lead screw drives the nut, lifting frame, brush head rotation control mechanism and brush head to move vertically downward in sync. At this time, the brush head is in a posture of rotating and descending at the same time, descaling the inner wall of the barrel from top to bottom. When the brush head descends to the bottom of the inner cavity of the barrel, motor B stops running for t seconds, so that the brush head descaling the bottom surface of the inner cavity of the barrel.

[0030] c. Motor B starts and drives the lead screw to rotate through the reducer. The rotation of the lead screw drives the nut, lifting frame, brush head rotation control mechanism and brush head to move vertically upward in sync. At this time, the brush head is in a posture of rotating and rising at the same time, which removes scale from the inner wall of the barrel from bottom to top. When the brush head rises to the top of the inner cavity of the barrel, motor B stops running.

[0031] S05, Brush head rotates to vertical position: Cylinder B starts, the piston of cylinder B retracts, driving the pull rod shaft to move vertically upward. The pull rod shaft drives the brush head to rotate around the sixth hinge of the J-shaped brush plate in the vertical plane through the connecting rod, so that the brush head rotates from the horizontal position to the vertical position.

[0032] In this step, when the brush head is in a vertical position, the vertical section of the J-shaped brush plate is parallel to the pull rod axis; when the brush head is in a horizontal position, the vertical section of the J-shaped brush plate is perpendicular to the pull rod axis.

[0033] S06, Brush head exits the inner cavity of the barrel: Motor B starts, and motor B drives the lead screw to rotate through the reducer. The rotation of the lead screw drives the nut, the lifting frame, the brush head rotation control mechanism and the brush head to move vertically upward in sync, so that the brush head completely exits the inner cavity of the barrel through the opening at the top of the barrel. When the lifting frame rises to the top of its movement stroke, motor B stops running.

[0034] S07, Unloading the electrolyte tank: The pistons of all cylinders A in the tank positioning kit retract synchronously, causing the four positioning blocks to detach from the outer wall of the electrolyte tank, and forming outlets at both ends of the tank's accommodating area for the tank to be pushed out; finally, the tank can be pushed out from the outlet.

[0035] A further technical solution of the present invention is: in step S03, when the brush head is in a vertical state, the vertical section of the J-shaped brush plate is parallel to the pull rod shaft, and when the brush head is in a horizontal state, the vertical section of the J-shaped brush plate is perpendicular to the pull rod shaft.

[0036] A further technical solution of the present invention is: in step S04, the value of t is 5 to 30, the rotation speed of the brush head is 30 to 60 revolutions / min, and the upward or downward speed of the brush head is 10 to 30 cm / min.

[0037] Compared with the prior art, the present invention has the following advantages:

[0038] 1. It is used for descaling the inner wall of electrolyte tanks. It has a good descaling effect, a high degree of automation, and is easy to operate. It avoids the contamination of the newly added electrolyte by impurities in the tank when the electrolyte is replaced (refilled).

[0039] 2. Under the control of the brush head lifting control mechanism and the brush head rotation control mechanism, the brush head can move vertically, as well as rotate in both the horizontal and vertical planes. Through combinations of different movement modes, the brush head can extend into or retract from the inner cavity of the electrolyte tank through the narrow opening at the top of the tank, and can also perform descaling operations without dead angles within the inner cavity of the electrolyte tank.

Detailed Implementation

[0058] Example 1:

[0059] like Figures 1-10 As shown, the descaling device for the inner wall of the electrolyte tank includes a frame 1, a tank positioning kit, a brush head lifting control mechanism, a brush head rotation control mechanism, and a brush head.

[0060] The upper part of the frame 1 is provided with a power receiving area 11, and the lower part of the frame 1 is provided with a material receiving area 12. The power receiving area 11 and the material receiving area 12 are positioned directly opposite each other. The bottom of the material receiving area 12 is provided with multiple rollers 13 arranged parallel to each other, at equal intervals and at equal heights. All the rollers 13 together form the material bearing surface at the upper end.

[0061] Two sets of bucket positioning kits are respectively located at the lower and upper ends of the bucket receiving area 12. Each set of bucket positioning kits includes four sets of bucket positioning components arranged in a ring at the same height. Each bucket positioning component includes a cylinder A21, a magnetic switch 22, and a positioning block 23. The cylinder A21 is fixedly mounted on the lower part of the frame 1, with its piston extending horizontally towards the inside of the bucket receiving area 12. The magnetic switch 22 is mounted on the cylinder A21 and is used to detect the stroke of the piston of the cylinder A21. The positioning block 23 is fixedly mounted on the end of the piston of the cylinder A21 and moves closer to or further away from the inside of the bucket receiving area 12 as the piston of the cylinder A21 extends and retracts. All the positioning blocks 23 in each set of bucket positioning kits form a positioning ring, which is located within the bucket receiving area 12, and the positioning rings formed by the two sets of bucket positioning kits are vertically aligned. The pistons of all cylinders A21 in the material tank positioning kit extend or retract synchronously, which can control the positioning ring to shrink or expand. Shrinking the positioning ring can position the electrolyte tank placed in the material tank receiving area 12. Expanding the positioning ring can push the electrolyte tank that has completed the descaling operation out of the material tank receiving area 12, or facilitate pushing the electrolyte tank to be descaled into the material tank receiving area 12.

[0062] The brush head lifting control mechanism is located within the power receiving area 11 of the frame 1. The brush head lifting control mechanism includes a guide rail 31, a slider 32, a lifting frame 33, and a lifting drive assembly. The guide rail 31 is fixedly installed within the power receiving area 11 of the frame 1 and is vertical. The slider 32 is fixedly installed on the lifting frame 33. The lifting frame 33 is slidably installed on the guide rail 31 via the slider 32. The lifting drive assembly is installed within the power receiving area 11 of the frame 1 and is associated with the lifting frame 33 to drive the lifting frame 33 to move vertically along the guide rail 31. The lifting drive assembly includes a lead screw 341, a nut 342, a motor B343, and a reducer 344. The lead screw 341 is movably installed within the power receiving area 11 of the frame 1 and is vertically arranged. The nut 342 is fixedly installed on the lifting frame 33 and threadedly connected to the lead screw 341. The motor B343 is fixedly installed at the upper end of the frame 1. The reducer 344 is fixedly installed on the upper end of the frame and is connected to the shaft of the motor B343 and the upper end of the lead screw 341 respectively. It is used to reduce the power of the motor B343 and transmit it to the lead screw 341.

[0063] The brush head rotation control mechanism includes a horizontal rotation component and a vertical rotation component. The horizontal rotation component includes a motor A411, a reducer 412, and a hollow shaft 413. The motor A411 is fixedly mounted on the lifting frame 33. The reducer 412 includes a housing 4121, a worm gear, and a worm. The housing 4121 is fixedly mounted on the lifting frame 33. The worm gear and worm are meshed inside the housing 4112. The worm is connected to the shaft of the motor A411. The worm gear is connected to the hollow shaft 413 via a key. The hollow shaft 413 is connected to the worm gear of the reducer 412 via a key and is arranged vertically. Its upper and lower ends extend from the upper and lower ends of the housing 4121 of the reducer 412, respectively. Its lower end is provided with a first hinge part 4131. The vertical rotation component includes a cylinder seat 421, a cylinder B422, a tie rod shaft 423, and a connecting rod 424. The cylinder seat 421 is fixedly connected to the upper end of the hollow shaft 413 and is located at the upper end of the reducer 412. The cylinder B422 is fixedly mounted on the cylinder seat 411, and its piston rod extends vertically downward. The tie rod shaft 423 is movably mounted in the inner hole of the hollow shaft 413, with its upper end extending from the opening at the upper end of the inner hole of the hollow shaft 413 and fixedly connected to the piston rod of the cylinder B422. Its lower end is provided with a second hinge portion 4231. The upper and lower ends of the connecting rod 424 are respectively provided with a third hinge portion 4241 and a fourth hinge portion 4242. The connecting rod 424 is hinged to the second hinge portion 4231 of the tie rod shaft 423 through the third hinge portion 4241.

[0064] The brush head includes a J-shaped brush plate 51 and bristles 52 bonded and fixed to the J-shaped brush plate 51. The J-shaped brush plate 51 includes a vertical plate segment 511, an arc-shaped transition plate segment 512, and a horizontal plate segment 513 connected in sequence. The included angle between the vertical plate segment 511 and the horizontal plate segment 513 is 90°. The end of the vertical plate segment 511 is provided with a fifth hinge portion 514, and the middle of the vertical plate segment 511 is provided with a sixth hinge portion 515. The J-shaped brush plate 51 is hinged to the fourth hinge portion 4242 of the connecting rod 424 through the fifth hinge portion 514, and the J-shaped brush plate 51 is hinged to the first hinge portion 4131 of the hollow shaft 413 through the sixth hinge portion 515.

[0065] Preferably, the four sets of tank positioning components included in the tank positioning kit are named Group 1, Group 2, Group 3, and Group 4 in a clockwise order. Specifically, the positioning blocks 23 in Groups 1 and 4 are directly opposite each other, as are the positioning blocks 23 in Groups 2 and 3. The cylinders A21 in Groups 1 and 2 are arranged in parallel, as are the cylinders A21 in Groups 3 and 4. This arrangement, compared to a diagonally opposite arrangement, effectively shortens the piston stroke of the cylinders, reduces the overall space occupied by the descaling device on the inner wall of the electrolyte tank, and facilitates precise control of the cylinder piston stroke.

[0066] Preferably, there are two guide rails 31 arranged parallel to each other, and correspondingly, there are two sliders 32, each slidingly engaging with one guide rail 31. This structure maintains better stability of the lifting frame's movement compared to a structure with a single guide rail and a single slider.

[0067] Preferably, the lower end of the hollow shaft 413 is provided with a clearance notch 4132 for the connecting rod 424 to extend. This structure allows the connecting rod 424 to have a larger rotation angle, thereby allowing the brush head to rotate at a larger angle in the vertical plane.

[0068] Preferably, the vertical rotation assembly also includes a conductive air guide slip ring 425 mounted on the upper end of the cylinder B422.

[0069] Briefly describe the brush head's motion control principle: The brush head rotation control mechanism controls the brush head's rotation in the vertical plane and / or horizontal plane. The brush head lifting control mechanism indirectly controls the vertical lifting of the brush head by controlling the vertical lifting of the brush head rotation control mechanism.

[0070] The control process for the brush head to rotate in the horizontal plane is as follows: Start motor A411. Motor A411 drives the worm and worm wheel of reducer 412 to rotate in sequence, which in turn drives the intermediate shaft 413, cylinder seat 421, cylinder B422, tie rod shaft 423 and connecting rod 424 to rotate synchronously in the horizontal plane. Finally, the connecting rod 424 drives the brush head to rotate in the horizontal plane.

[0071] The control process for the vertical rotation of the brush head is as follows: Start cylinder B422. Cylinder B422 drives the pull rod shaft 423 to move vertically through the extension and retraction of the piston. The pull rod shaft 423 drives the brush head to rotate around the sixth hinge 515 of the J-shaped brush plate 51 in the vertical plane through the connecting rod 424, thereby switching the brush head between vertical and horizontal states. When the brush head is in the vertical state, the vertical section 511 of the J-shaped brush plate 51 is vertical (parallel to the pull rod shaft 423). When the brush head is in the horizontal state, the vertical section 511 of the J-shaped brush plate 51 is horizontal (perpendicular to the pull rod shaft 423).

[0072] The control process for vertical lifting of the brush head is as follows: Start motor B343. Motor B343 drives lead screw 341 to rotate through reducer 344. The rotation of lead screw 341 drives nut 342, lifting frame 33, brush head rotation control mechanism and brush head to move vertically and vertically in sync.

[0073] Briefly describe the working process of the present invention: The efficient and convenient descaling device for the inner wall of the electrolyte tank is used to remove the dirt attached to the inner wall of the electrolyte tank. The electrolyte tank includes a tank body 61 and a tank cover 62. The tank body 61 is cylindrical and has an opening 611 at the center of its upper end. The tank cover 62 is placed on the opening at the upper end of the tank body 61.

[0074] Before the descaling operation, the efficient and convenient descaling device for the inner wall of the electrolyte tank is in its initial state. In the initial state:

[0075] a. All pistons of cylinders A21 in the hopper positioning kit are in the retracted state;

[0076] b. The lifting frame 33 is at the top of its travel stroke;

[0077] c. Rotate the brush head to a vertical position.

[0078] The descaling procedure is as follows:

[0079] S01, Loading the electrolyte tank: Remove the lid 62 of the electrolyte tank to be descaled, place the tank body 61 on the tank support surface at the bottom of the frame 1, and push it into the positioning ring of the tank positioning kit. At this time, the entire tank body 61 is located in the tank receiving area 12 at the bottom of the frame 1. Then, the pistons of all cylinders A21 in the tank positioning kit extend synchronously, causing the positioning ring to gradually shrink. Finally, all the positioning blocks 23 in the tank positioning kit abut against the outer wall of the electrolyte tank body 61, positioning the electrolyte tank body 61 in the center area of ​​the tank receiving area 12. At this time, the brush head is located directly above the opening 611 at the top of the tank body 61.

[0080] S02: Brush head inserted into the inner cavity of the barrel: Motor B343 starts, and motor B343 drives lead screw 341 to rotate through reducer 344. The rotation of lead screw 341 drives nut 342, lifting frame 33, brush head rotation control mechanism and brush head to move vertically downward in sync. When the brush head is fully inserted into the inner cavity of barrel 61 through the upper opening 611 of barrel 61, motor B343 stops running.

[0081] S03: Brush head rotates to horizontal state: Cylinder B422 is started, the piston of cylinder B422 extends, driving the pull rod shaft 423 to move vertically downward. The pull rod shaft 423 drives the brush head to rotate around the sixth hinge part 515 of the J-shaped brush plate 51 in the vertical plane, so that the brush head rotates from the vertical state to the horizontal state. At this time, the bristles 52 on the horizontal section 513 of the J-shaped brush plate 51 contact the uppermost end of the inner cavity side wall of the barrel.

[0082] In this step, when the brush head is in a vertical position, the vertical section 511 of the J-shaped brush plate 51 is parallel to the pull rod shaft 423; when the brush head is in a horizontal position, the vertical section 511 of the J-shaped brush plate 51 is perpendicular to the pull rod shaft 423.

[0083] S04, Descaling the inner wall of the tank:

[0084] a. When motor A411 starts, motor A411 drives hollow shaft 413 to rotate through reducer 412. When hollow shaft 413 rotates, it drives vertical rotating component and brush head to rotate synchronously on the horizontal plane.

[0085] b. When motor B343 starts, motor B343 drives lead screw 341 to rotate through reducer 344. The rotation of lead screw 341 drives nut 342, lifting frame 33, brush head rotation control mechanism and brush head to move vertically downward in sync. At this time, the brush head is in a posture of rotating and descending at the same time, descaling the inner wall of barrel 61 from top to bottom.
