Description

Technical Field

[0001] The utility model belongs to the technical field of electric furnaces, and particularly relates to an electrode lifting device for a yellow phosphorus electric furnace. Background Art

[0002] Yellow phosphorus, an allotrope of phosphorus, is a pale yellow crystal with a garlic smell. It is highly toxic, has a very low ignition point, can spontaneously combust, and glows in the air. It can be used to make ordinary matches and is used in the military to make smoke bombs. The production process of yellow phosphorus is relatively simple. Phosphate ore, silica, and coke are placed in an electric furnace in a certain proportion and particle size. Decomposition and reduction reactions occur at a high temperature of more than 1,000 degrees. The phosphorus vapor and furnace dust are cooled and rinsed together to obtain the product, and the high-temperature slag is directly discharged from the electric furnace.

[0003] During the yellow phosphorus production process, the electrodes of the electric furnace need to be raised and lowered. Traditionally, this is achieved using a worm gear drive. However, due to the coordinated adjustment of the worm, worm, copper sleeve, and lead screw, this traditional lifting device is easily damaged during use, resulting in high costs and energy consumption. In recent years, hydraulic lifting devices have also been adopted for control. For example, application number 202320198011.X, titled "Horizontal Hydraulic Lifting Device for Yellow Phosphorus Furnace Electrodes," uses a ring clamp to clamp and secure the electrodes, and a steel wire rope connected to a hydraulic cylinder to pull the electrodes up and down.

[0004] However, since the steel wire rope is directly connected to the hydraulic cylinder in the prior art, the load borne by the hydraulic cylinder during the lifting process is too large, which is not conducive to the subsequent maintenance of the hydraulic electrode lifting device and reduces the service life of the hydraulic cylinder.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] The following combination Figures 1 and 2 The utility model is described in detail.

[0026] A yellow phosphorus electric furnace electrode lifting device, in some embodiments, such as Figures 1 and 2 As shown, it includes a hydraulic cylinder with a cylinder body 2 fixedly connected to a steel platform 1, the outer end of the piston rod 3 of the hydraulic cylinder is fixedly connected to a counterweight block 4, the counterweight block 4 is slidably connected to the steel platform 1, and the counterweight block 4 is rotatably connected to three drive disks 5 at the end away from the hydraulic cylinder; each of the drive disks 5 is respectively sleeved with a traction chain 6 on the outside, one end of the traction chain 6 is connected to the steel platform 1 through a connecting piece 7, and the position of the connecting piece 7 is set between the counterweight block 4 and the cylinder body 2; the other end of each of the traction chains 6 extends into the bottom of the steel platform 1 through a guide assembly, and is evenly connected to the outside of the annular electrode clamp 8.

[0027] During specific use, when the electric furnace electrode 19 needs to be lifted or lowered, the piston rod 3 of the hydraulic cylinder is controlled to extend or retract, pushing the counterweight block 4 to slide on the steel platform 1, thereby driving the drive disk 5 to move. At the same time, under the gravity of the electric furnace electrode 19, the traction chain 6 drives the drive disk 5 to rotate. Since one end of the traction chain 6 is connected to the steel platform 1 through the connecting piece 7, during the rotation of the drive disk 5, the traction chain 6 moves and turns to the bottom of the counterweight block 4, so that all the drive disks 5 become a movable pulley set. Under the action of the lever principle, the hydraulic cylinder only needs to provide half the gravity of the electric furnace electrode 19. Compared with the direct connection between the traction wire rope and the hydraulic cylinder in the prior art, the load borne by the hydraulic cylinder during the lifting process of this device can be reduced by half, which is beneficial to the subsequent maintenance of the hydraulic electrode lifting device and increases the service life of the hydraulic cylinder.

[0028] In some embodiments, as Figures 1 and 2 As shown, the steel platform 1 is also provided with two support rods 9 whose ends are fixedly connected to the steel platform 1 through support blocks, and the axis of the support rod 9 is parallel to the axis direction of the piston cylinder; the two sides of the counterweight block 4 are fixedly connected with sliding blocks 10, and the sliding blocks 10 are sleeved on the outside of the support rod 9 and are slidably connected to the support rod 9.

[0029] During specific use, the counterweight block 4 is supported by the support block and the support rod 9, and the sliding block 10 is sleeved on the outside of the support rod 9 and slidably connected to the support rod 9, thereby realizing the sliding connection between the counterweight block 4 and the steel platform 1.

[0030] In some embodiments, as Figures 1 and 2As shown, the counterweight block 4 is fixedly connected to a mounting seat 11 at one end away from the hydraulic cylinder, two first fixing plates 12 are arranged on the mounting seat 11, and the driving disc 5 is rotatably arranged between the two first fixing plates 12 through a pin shaft.

[0031] During specific use, the driving disc 5 is rotatably arranged between the two first fixing plates 12 via a pin shaft, thereby realizing a rotational connection between the driving disc 5 and the counterweight 4 .

[0032] In some embodiments, as Figures 1 and 2 As shown, the outer side of the driving disc 5 is provided with a first groove 13 that matches the traction chain 6 .

[0033] During specific use, the traction chain 6 is fitted into the first groove 13 to prevent the traction chain 6 from being deflected or even detached during the traction process, thereby preventing a production accident.

[0034] In some embodiments, as Figures 1 and 2 As shown, the steel platform 1 is further provided with a plurality of supporting mechanisms for supporting the traction chain 6 , and the supporting mechanisms are arranged between the cylinder body 2 and the guide assembly.

[0035] During specific use, during the traction process of the traction chain 6 , the support mechanism supports the traction chain 6 to prevent the traction chain 6 from falling, which is not conducive to the lifting and lowering of the electric furnace electrode 19 .

[0036] In some embodiments, as Figures 1 and 2 As shown, the support assembly includes a support base 14 fixedly connected to the steel platform 1, and two second fixed plates 15 are arranged on the support base 14. A support plate 16 is rotatably connected between the two second fixed plates 15 through a pin shaft. The support plate 16 is supported under the traction chain 6, and a second groove 17 is provided on the outer side of the support plate 16 to cooperate with the traction chain 6.

[0037] During specific use, during the traction process, the support plate 16 supports the traction chain 6 and rotates with the traction of the traction chain 6, thereby reducing adverse effects on the movement of the traction chain 6 during the support process.

[0038] In some embodiments, as Figures 1 and 2 As shown, each of the traction chains 6 is provided with a disc-shaped suspension porcelain insulator 18 .

[0039] During specific use, the smooth transmission of current on the furnace electrode 19 is ensured, and current leakage or short circuit is prevented.

[0040] In some embodiments, as Figures 1 and 2As shown, the guide assembly includes a guide seat 20 fixedly connected to the steel platform, two third fixed plates 21 are arranged on the guide seat 20, and a guide plate 22 is rotatably connected between the two third fixed plates 21 through a pin shaft. The guide plate 22 is supported under the traction chain 6, and a third groove 23 is provided on the outer side of the guide plate 22 to cooperate with the traction chain 6.

[0041] During specific use, the traction chain is turned by the guiding action of the guide disc, thereby being connected to the annular electrode holder located below the steel platform.

[0042] In some other embodiments, unlike the above embodiment, the bottom of the connecting member 7 is fixedly connected to the steel platform 1, and the connecting member 7 is hinged to the end of the traction chain 6. In specific use, the connecting member 7 is hinged to the end of the traction chain 6, thereby increasing the range of movement of the end of the traction chain 6, which is beneficial to the traction of the electric furnace electrode 19.

[0043] It is worth mentioning that lubricant can be added to the first groove 13 and the second groove 17 to reduce the relative friction between the traction chain 6 and the driving plate 5 and the support plate 16, which is beneficial to the traction of the traction chain 6.

[0044] The operating principle of this device:

[0045] When the electric furnace electrode 19 needs to be lifted or lowered, the piston rod 3 of the hydraulic cylinder is controlled to extend or retract, pushing the counterweight block 4 to slide on the steel platform 1, thereby driving the drive disk 5 to move. At the same time, under the gravity of the electric furnace electrode 19, the traction chain 6 drives the drive disk 5 to rotate. Since one end of the traction chain 6 is connected to the steel platform 1 through the connecting piece 7, the traction chain 6 moves and turns to the bottom of the counterweight block 4 during the rotation of the drive disk 5, so that all the drive disks 5 become a movable pulley set. Under the action of the lever principle, the hydraulic cylinder only needs to provide half the gravity of the electric furnace electrode 19. Compared with the direct connection between the traction wire rope and the hydraulic cylinder in the prior art, the load borne by the hydraulic cylinder during the lifting process of this device can be reduced by half, which is beneficial to the subsequent maintenance of the hydraulic electrode lifting device and increases the service life of the hydraulic cylinder.

[0046] The above-described embodiments merely represent specific implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the technical concept of the present application, and all such variations and improvements fall within the scope of protection of the present application.
