Description

Technical Field

[0001] The present invention relates to the technical field of electrolytic aluminum, and in particular to an equipment for electrolysis, specifically a sealing device for the anode rod of an electrolytic cell. Background Art

[0002] The horizontal cover plate of the electrolytic cell is provided with an opening for installing the anode rod. The size of the opening is larger than that of the anode rod. After the anode rod is placed in the opening, two gaps are formed between the two sides of the anode rod along the placing direction and the horizontal cover plate of the electrolytic cell. If the two gaps are not sealed or are not sealed tightly, the toxic substances generated during the electrolysis production process will be released outward, resulting in energy loss of the electrolytic cell and environmental pollution. Therefore, it is necessary to seal these gaps.

[0003] Currently, there are various ways in the art to seal the gap between the anode rod and the horizontal cover plate of the electrolytic cell, but there are also some deficiencies.

[0004] For example, the patent with the authorization publication number CN 219010484 U discloses a sealing device for the guide rod of an aluminum electrolytic cell, which uses a driving mechanism to drive the first sealing member and the second sealing member to move relative to each other so that they can seal the anode guide rod. When replacing the guide rod, the driving mechanism drives the first sealing member and the second sealing member away from the anode rod, which can avoid friction between the sealing member and the anode rod. This device controls the first sealing member and the second sealing member through additional power, and it is necessary to precisely control the driving mechanism, making it difficult to ensure that the first sealing member and the second sealing member move away from the anode rod in time when replacing the guide rod. In addition, the first sealing member and the second sealing member do not have buffering performance, and their impact resistance to the anode rod is poor, so the whole device is easily damaged; moreover, the first sealing member and the second sealing member are relatively fixed, and the sealing effect is poor.

[0005] For another example, the patent with the authorization publication number CN 205710960 U discloses a sealing device for the anode rod of an electrolytic cell. When the anode rod is placed in the opening, it is necessary to pull the first movable rod and the second movable rod outward by an external force. When replacing the anode rod, it is also necessary to pull the first movable rod and the second movable rod outward by an external force, and the whole operation is relatively cumbersome.

[0006] For another example, the patent with the authorization announcement number CN 204644483 U discloses a movable sealing device for the anode guide rod of an aluminum electrolytic cell, which includes a fixed sealing body and two movable sealing bodies. The two movable sealing bodies are located on both sides of the opening of the sealing structure, and each movable sealing body is provided with a high magnetic permeability material. When the anode guide rod enters the opening of the sealing structure and is energized, the large current of the anode guide rod itself acts on the high magnetic permeability material in the movable sealing body, sucking the movable sealing body out of the cover plate and the bottom plate until the sealing cloth or brush contacts the anode guide rod to complete the sealing; when the anode guide rod is removed and the current does not exist, the movable sealing body resets under the action of the spring and returns to the cover plate and the bottom plate. This patent uses electromagnetic action to control the movement of the movable sealing body, which has certain dangers, and the structure is complex and the stability is poor.

[0007] For another example, the patent with the application publication number CN 104178778 A discloses an anode guide rod sealing device, which uses a lever formed by a horizontal connecting rod and a vertical connecting rod. When the anode guide rod is placed in the opening of the horizontal cover plate of the electrolytic cell, the anode guide rod pushes one end of the lever to rotate around the fulcrum (hinged support), and the other end of the lever correspondingly controls the sealing unit to contact the anode guide rod and achieve sealing. The sealing units on both sides of the anode guide rod completely rely on a compression spring (elastic element) to abut against the anode guide rod for sealing, and the stability of the sealing unit is poor; moreover, the widths of the gaps on both sides of the anode guide rod are often not equal, and the sealing units on both sides of the anode guide rod have poor adaptability to this, affecting the sealing effect. Summary of the Invention

[0008] The present invention provides an anode guide rod sealing device for an electrolytic cell, aiming to effectively seal the gap between the anode guide rod and the horizontal cover plate of the electrolytic cell automatically after the anode guide rod is placed in the opening of the horizontal cover plate of the electrolytic cell.

[0009] The technical solution adopted by the present invention is as follows: an electrolytic cell anode guide rod sealing device, which includes a bottom plate, a sliding seat, a moving member, a trigger block and a sealing member. An opening for installing the anode guide rod is provided on one side of the bottom plate. It is assumed that the plane corresponding to the bottom plate is a horizontal plane. The direction in which the anode guide rod enters the opening along the horizontal plane is forward, and the direction in which the anode guide rod is taken out of the opening along the horizontal plane is backward. The two directions perpendicular to the front-back direction and horizontal are respectively left and right; the electrolytic cell anode guide rod sealing device is an axisymmetric structure, and the axis of symmetry is the midline of the opening along the front-back direction; two sliding seats are fixedly arranged on the bottom plate, and a moving member is installed in each of the two sliding seats. The moving member includes a sliding rod and a sealing rod that are perpendicular to each other. The sliding rod is slidably installed in the sliding seat and can move along the left-right direction. A reset member is also provided between the moving member and the sliding seat or between the moving member and the bottom plate to automatically reset the moving member after it approaches the opening. The two sliding rods are connected by a trigger block. The trigger block includes a pushing portion and a reversing portion on the front side of the pushing portion. The pushing portion is located on the front side of the opening. The reversing portion is provided with two guiding grooves, and the two guiding grooves are in a shape of an inverted V in the horizontal plane. The sliding rods of the two moving members are respectively movably connected to the two guiding grooves. When the trigger block moves forward, the two moving members approach the opening along the left-right direction respectively; the sealing rods of the two moving members are both arranged along the front-back direction and are respectively located on the left and right sides of the opening. The sealing rod is provided with at least two through holes, and the center lines of each through hole are arranged along the left-right direction. A sealing member is connected to the side of the sealing rod facing the opening. A guiding shaft corresponding to the through hole of the sealing rod is provided on the side of the sealing member facing away from the opening. The guiding shaft penetrates through the through hole of the sealing member and is fixed by a nut. At least one pushing spring is also provided between the sealing rod and the sealing member.

[0010] In order to enable the sliding rod of the moving member to move flexibly in the guiding groove, further: a pin shaft is installed at the end of the sliding rod close to the opening, and a bearing is installed on the pin shaft, and the bearing is located in the guiding groove.

[0011] The bottom plate is generally a conductor such as a steel plate. In order to insulate the bottom plate after installation, further: an insulating layer is provided on the bottom surface of the bottom plate. The bottom plate is provided with mounting holes, and bolts equipped with insulating sleeves are provided in the mounting holes.

[0012] In order to insulate between the trigger block and the anode guide rod and buffer the impact of the anode guide rod on the trigger block, further: an insulating layer is provided on the side of the reversing portion of the trigger block for abutting against the anode guide rod.

[0013] Specifically: a cover plate is fixedly installed on the side of the reversing portion of the trigger block facing the opening. A spherical segment-shaped card slot is provided in the cover plate. The cover plate is provided with a hole adapted to the card slot. An insulating ball is fixed in the card slot, and the insulating ball protrudes out of the hole of the cover plate.

[0014] The resetting member is used to automatically reset the moving member after it approaches the opening, so that the sealing member is reset outside the left and right sides of the opening. Specifically: a limiting member is provided at one end of the sliding rod of the moving member away from the opening, and a reset spring is sleeved outside the sliding rod. The two ends of the reset spring are respectively abutted against the limiting member and the sliding seat.

[0015] In order to ensure the stability of the pushing spring and have sufficient deformation, further: the pushing spring is arranged on the outer periphery of the guiding shaft, or the sealing rod is provided with a spring mounting hole, and the pushing spring is mounted in the spring mounting hole.

[0016] The sealing member is used to directly abut against the anode guide rod and maintain the seal. In order to enable the two sealing members and the pushing part of the trigger block to better abut against the anode guide rod, further: the two sealing members are L-shaped in the horizontal plane. When the moving member moves to the limit position in the direction close to the opening, one end of each of the two sealing members abuts against the pushing part of the trigger block and forms a U-shaped notch.

[0017] In order to improve the sealing effect after the sealing member abuts against the anode guide rod, further: the sealing member includes a clamping groove and a flexible sealing strip fixed in the clamping groove. The cross-section of the clamping groove is U-shaped, and the notch of the clamping groove faces the opening of the bottom plate.

[0018] In order to facilitate the quick fixing and removal of the flexible sealing strip, further: two supporting seats are fixedly arranged on the clamping groove. A through hole is provided in the clamping groove between the two supporting seats. A pin shaft is arranged between the two supporting seats. The pin shaft passes through an eccentric pressing wheel for fastening the flexible sealing strip in the clamping groove, and a pressing strip is arranged between the eccentric pressing wheel and the flexible sealing strip.

[0019] The beneficial effects of the present invention are as follows: Before the anode guide rod is placed into the opening horizontally forward, the resetting member makes the moving members on the left and right sides of the opening move leftward and rightward respectively. At this time, the sealing members on both sides of the opening are located outside both sides of the opening, and the sealing members will not affect the anode guide rod being placed into the opening horizontally forward. When the anode guide rod is placed into the opening horizontally forward, the anode guide rod contacts the commutation part of the trigger block and pushes the commutation part forward. Under the action of the guiding groove, the moving member approaches the opening in the left and right directions, so that the trigger block and the two sealing members abut against and seal the anode guide rod from three directions. A guiding shaft and a pushing spring are arranged between the sealing rod and the sealing member, so that the sealing member can abut against the anode guide rod well and maintain the seal. After the anode guide rod is taken out of the opening horizontally backward, the resetting member makes the moving member automatically move away from the opening in the left and right directions and reset, and the sealing member is automatically separated from the anode guide rod, avoiding friction between the sealing member and the anode guide rod. The structure of the present invention is simple, the operation stability is good, it can effectively seal the gap of the anode guide rod in the opening, greatly reduce the environmental problems caused by the disorderly release of dust and soot from the electrolytic cell, and also reduce the problem of a large amount of heat energy taken away by the same.

Detailed implementation manners

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] As Figure 1 and Figure 2 shown, the anode rod sealing device of the electrolytic cell of the present invention includes a bottom plate 1, a sliding seat 2, a moving member 3, a trigger block 4, and a sealing member 5. One side of the bottom plate 1 is provided with an opening 1-1 for installing the anode rod 6. The opening 1-1 is rectangular, and the size of the opening 1-1 is larger than the size of the anode rod 6. For the convenience of description, it is set that the plane corresponding to the bottom plate 1 is a horizontal plane, the direction in which the anode rod 6 enters the opening 1-1 along the horizontal plane is forward, the direction in which the anode rod 6 is taken out of the opening 1-1 along the horizontal plane is backward, and the two directions perpendicular to the front and back directions and horizontal are respectively left and right. The anode rod sealing device of the electrolytic cell is an axisymmetric structure, and the axis of symmetry is the midline of the opening 1-1 along the front and back directions, that is, the sliding seat 2, the moving member 3, the trigger block 4, and the sealing member 5 are axially symmetrically arranged along the midline of the opening 1-1 in the front and back directions.

[0028] The bottom plate 1 is generally rectangular to facilitate fixed installation on the cell ledge plate. For the convenience of installing and fixing the bottom plate 1 by bolts, the bottom plate 1 can also be provided with mounting holes 1-2 for passing bolts. For example, refer to Figure 1 and Figure 2, the bottom plate 1 is rectangular, and mounting holes 1-2 are respectively provided at the four corners of the bottom plate 1. Each mounting hole 1-2 is respectively equipped with a suitable bolt. In order to insulate the bottom plate 1 after installation, the bottom plate 1 can be made of an insulating material. When the bolt is made of metal, an insulating sleeve is provided in the mounting hole 1-2 of the bottom plate 1 for the bolt. In order to ensure the strength of the bottom plate 1, the bottom plate 1 is generally a conductor such as a steel plate. In order to insulate the bottom plate 1 after installation, an insulating layer is provided on the bottom surface of the bottom plate 1 to insulate the bottom plate 1 from the groove eyebrow plate. For example, the insulating layer is felt and fixed to the entire bottom surface of the bottom plate 1. The bottom plate 1 is provided with mounting holes 1-2, and insulating sleeves are provided in the mounting holes 1-2 for the bolts to prevent the bolts from conducting electricity.

[0029] Two sliding seats 2 are fixedly arranged on the bottom plate 1. A moving member 3 is respectively installed in the two sliding seats 2. The moving member 3 can reciprocate linearly along the sliding seat 2, and the moving direction is the left-right direction. The moving member 3 mainly includes two parts, namely a sliding rod 3-1 and a sealing rod 3-2 that are perpendicular to each other. The sliding rod 3-1 and the sealing rod 3-2 are an integral body or fixedly connected. The sliding rod 3-1 is slidably installed in the sliding seat 2 and can move along the left-right direction. The two sliding rods 3-1 are on the same straight line, and the two sliding rods 3-1 are connected by a trigger block 4, that is, the two sliding rods 3-1 are respectively movably connected to the trigger block 4.

[0030] See Figure 1 , Figure 2 and Figure 3 , the trigger block 4 includes a pushing portion 4-1 and a reversing portion 4-2 on the front side of the pushing portion 4-1. The pushing portion 4-1 and the reversing portion 4-2 are an integral body or fixedly connected. The trigger block 4 is used to contact the anode guide rod 6. After the trigger block 4 contacts the anode guide rod 6, it drives the moving member 3 to move in the direction close to the opening 1-1. The pushing portion 4-1 can directly contact the anode guide rod 6. The pushing portion 4-1 is located on the front side of the opening 1-1, as Figure 1 shown. The reversing portion 4-2 is provided with two guiding grooves 4-3. The two guiding grooves 4-3 are in an eight-shaped pattern in the horizontal plane. The sliding rods 3-1 of the two moving members 3 are respectively movably connected to the two guiding grooves 4-3. When the trigger block 4 moves forward, the two moving members 3 respectively move close to the opening 1-1 along the left-right direction. In order to enable the sliding rod 3-1 of the moving member 3 to move flexibly in the guiding groove 4-3, a pin shaft is installed at the end of the sliding rod 3-1 close to the opening 1-1, and a bearing is installed on the pin shaft. The bearing is preferably stuck in the guiding groove 4-3 to ensure the stability of the movable connection. The trigger block 4 is not fixed relative to the bottom plate 1. In order to facilitate the movable connection between the sliding rod 3-1 and the trigger block 4 and enable the sliding rod 3-1 and the trigger block 4 to bear force smoothly, the thicknesses of the two ends of the trigger block 4 in the front-rear direction are greater than the thickness of the middle portion to leave enough space for installing the pin shaft for the sliding rod 3-1.

[0031] A reset member is further provided between the moving member 3 and the sliding seat 2 or between the moving member 3 and the bottom plate 1 for automatically resetting the moving member 3 after it approaches the opening 1-1. In the natural state, that is, when the anode guide rod 6 does not apply force to the trigger block 4, as Figure 1 shown, the reset member keeps both moving members 3 away from the opening 1-1. At this time, the pushing portion 4-1 is located in the opening 1-1 to the greatest extent. The anode guide rod 6 moves forward along the horizontal plane and enters the opening 1-1. The anode guide rod 6 contacts the reversing portion 4-2 of the trigger block 4 and pushes the reversing portion 4-2 forward, and the reset member undergoes elastic deformation and stores energy. When the anode guide rod 6 moves backward along the horizontal plane and is taken out of the opening 1-1, the reset member resets the moving member 3 to the state of being away from the opening 1-1. The reset member can be a spring, a torsion spring or other elastic members. For example, referring to Figure 1 and Figure 2 , a limiting member 3-3 is provided at one end of the sliding rod 3-1 away from the opening 1-1. A reset spring 3-4 is sleeved outside the sliding rod 3-1. Two ends of the reset spring 3-4 are respectively abutted against the limiting member 3-3 and the sliding seat 2. To facilitate the adjustment of the reset spring 3-4, an external thread is provided at one end of the sliding rod 3-1 away from the opening 1-1. The limiting member 3-3 is a nut, and a gasket is also provided between the nut and the reset spring 3-4.

[0032] The sealing rods 3-2 of the moving member 3 are used to install the sealing member 5. Therefore, the two sealing rods 3-2 are both arranged in the front-rear direction and are respectively located on the left and right sides of the opening 1-1. To ensure that the sealing member 5 can seal well after abutting against the anode guide rod 6, especially to adapt to the vibration during production, the sealing member 5 is installed on the sealing rod 3-2 in a non-fixed manner. The sealing rod 3-2 is provided with at least two through holes. The center lines of the through holes are arranged in the left-right direction. The sealing member 5 is connected to the side of the sealing rod 3-2 facing the opening 1-1. On the side of the sealing member 5 facing away from the opening 1-1, guide shafts 5-1 corresponding to the through holes of the sealing rod 3-2 one by one are provided. The guide shafts 5-1 are arranged in the left-right direction. The guide shafts 5-1 pass through the through holes of the sealing member 5 and are fixed by nuts. At least one pushing spring 5-2 is further provided between the sealing rod 3-2 and the sealing member 5. To ensure the stability of the pushing spring 5-2, the pushing spring 5-2 is arranged on the outer periphery of the guide shaft 5-1, or at least one end of the pushing spring 5-2 is fixedly installed, or both ends of the pushing spring 5-2 are respectively fixed to the sealing rod 3-2 and the sealing member 5. To ensure that the pushing spring 5-2 has sufficient deformation, as Figure 1 and Figure 2As shown, two push springs 5-2 are arranged between the sealing rod 3-2 and the seal 5. The sealing rod 3-2 is provided with spring mounting holes, and the push springs 5-2 are installed in the spring mounting holes. The guide shaft 5-1 enables the seal 5 to be movable within a small range relative to the sealing rod 3-2 in the left-right direction, well adapting to the problem of poor sealing caused by vibration during the production process. The end of the guide shaft 5-1 is fixed by a nut, facilitating the adjustment of the movement stroke of the seal 5 relative to the sealing rod 3-2 in the left-right direction.

[0033] In the natural state, the anode guide rod 6 does not exert a force on the trigger block 4. As Figure 1 shown, the reset member keeps both moving members 3 away from the opening 1-1. At this time, one end of the sliding rod 3-1 is generally located at one end of the guide groove 4-3, and the seal 5 is located outside the opening 1-1. The anode guide rod 6 moves forward along the horizontal plane and enters the opening 1-1. The anode guide rod 6 contacts the reversing portion 4-2 of the trigger block 4 and pushes the reversing portion 4-2 forward. Under the action of the guide groove 4-3, the two moving members 3 synchronously approach the opening 1-1 in the left-right direction. The trigger block 4 and the two seals 5 abut and seal the anode guide rod 6 from three directions. As Figure 2 shown.

[0034] In order to insulate between the trigger block 4 and the anode guide rod 6 and buffer the impact of the anode guide rod 6 on the trigger block 4, an insulating layer is provided on the side of the reversing portion 4-2 of the trigger block 4 for abutting against the anode guide rod 6. For example, referring to Figure 3 and Figure 4 , a cover plate 4-4 is fixedly installed on the side of the reversing portion 4-2 of the trigger block 4 facing the opening 1-1. For example, the cover plate 4-4 is fixed to the side of the reversing portion 4-2 facing the opening 1-1 by two screws. The cover plate 4-4 is provided with a spherical segment-shaped card slot, and the cover plate 4-4 is provided with a hole adapted to the card slot. An insulating ball 4-5 is fixed in the card slot, and the insulating ball 4-5 protrudes outside the hole of the cover plate 4-4. The insulating ball 4-5 can roll in the card slot, reducing the frictional force between the trigger block 4 and the anode guide rod 6 and playing an insulating role.

[0035] The seal 5 is used to directly abut against the anode guide rod 6 and maintain the seal. In order to enable the two seals 5 and the pushing portion 4-1 of the trigger block 4 to better abut against the anode guide rod 6, referring to Figure 1 and Figure 2 , the two seals 5 are L-shaped in the horizontal plane. When the moving member 3 moves to the limit position in the direction close to the opening 1-1, one ends of the two seals 5 abut against the pushing portion 4-1 of the trigger block 4 and form a U-shaped notch, which is adapted to the anode guide rod 6.

[0036] In order to improve the sealing effect after the seal 5 abuts against the anode guide rod 6, the seal 5 includes a clamping groove 5-3 and a flexible sealing strip 5-4 fixed in the clamping groove 5-3. The cross-section of the clamping groove 5-3 is in a U shape to facilitate fixing the flexible sealing strip 5-4 in the clamping groove 5-3. The notch of the clamping groove 5-3 faces the opening 1-1 of the bottom plate 1, and the width of the flexible sealing strip 5-4 is greater than the depth of the clamping groove 5-3, so as to prevent the clamping groove 5-3 from directly contacting the anode guide rod 6 and the trigger block 4, but rather the flexible sealing strip 5-4 directly contacts the anode guide rod 6 and the trigger block 4.

[0037] After the flexible sealing strip 5-4 has been used for a period of time, it needs to be replaced. In order to facilitate the quick fixing and removal of the flexible sealing strip 5-4, the flexible sealing strip 5-4 is preferably fixed in an easy-to-dismount and easy-to-assemble manner. For example, refer to Figure 5 , two supporting seats are fixedly arranged on the clamping groove 5-3. A through hole is provided in the clamping groove 5-3 between the two supporting seats. A pin shaft is arranged between the two supporting seats. The pin shaft passes through an eccentric pressing wheel 5-5. The eccentric pressing wheel 5-5 can rotate around the pin shaft. After the eccentric pressing wheel 5-5 rotates, the eccentric pressing wheel 5-5 can fasten the flexible sealing strip 5-4 in the clamping groove 5-3 or loosen the flexible sealing strip 5-4. In order to enable the eccentric pressing wheel 5-5 to more stably fix the flexible sealing strip 5-4, a pressing strip 5-6 is provided between the eccentric pressing wheel 5-5 and the flexible sealing strip 5-4. The eccentric pressing wheel 5-5 directly presses on the pressing strip 5-6, and the pressing strip 5-6 and the clamping groove 5-3 clamp the flexible sealing strip 5-4.
