Description

Technical Field

[0001] This utility model relates to the field of yellow phosphorus electric furnace technology, specifically to a phosphorus furnace electrode sealing device. Background Technology

[0002] The yellow phosphorus electric arc furnace is an industrial piece of equipment specifically designed for the production of yellow phosphorus, widely used in chemical and metallurgical fields. During production, the furnace converts phosphate rock into high-purity yellow phosphorus through electrolysis or melting to meet various chemical and industrial demands. Electrodes, as an indispensable component of the furnace, play a crucial role in conducting current and promoting chemical reactions. Penetrating the furnace top and extending deep into the furnace chamber, the electrodes' sealing performance is critical to yellow phosphorus production. The main function of the electrode sealing device is to effectively seal off toxic gases within the furnace chamber, preventing the leakage of phosphorus-forming vapors, carbon monoxide, and other harmful gases generated during the reaction through the gap between the electrode and the furnace cover. This not only affects the health and safety of workers but also poses potential hazards to the environment and equipment. Therefore, ensuring good electrode sealing is essential for improving production efficiency, protecting operator safety, and maintaining environmental sustainability.

[0003] Patent CN212712753U discloses a novel electrode sealing device for a yellow phosphorus electric furnace, including a mounting base with a first through hole and a water seal groove at the upper end of the mounting base. A water seal cover is movably connected to the water seal groove, and a second through hole is opened at the upper end of the water seal cover. Electrodes are inserted into the second through hole and the first through hole. Symmetrically arranged semi-circular covers are movably connected to the upper end of the water seal cover, and a semi-circular sealing gasket is fixedly connected to the inner side of the semi-circular cover. A groove is opened at the upper end of the semi-circular cover, and a counterweight is movably connected to the groove. A first through groove is symmetrically arranged on the outer side of the mounting base, and an annular groove is opened at the lower end of the mounting base. This invention features an insertion rod to facilitate the connection between the mounting base and the water seal cover, improving the sealing effect. The added water seal groove can perform water sealing and facilitates the disassembly and assembly of the counterweight. Furthermore, the design of the limiting plate and the second spring ensures the stability of the insertion rod position.

[0004] The existing technology described above uses structures such as insert rods, limiting plates, and second springs to fix the water seal cover to the mounting base. When disassembling or assembling the water seal cover, both insert rods need to be pulled outwards simultaneously. This makes it difficult for a single worker to remove the water seal cover by pulling the two insert rods with both hands, resulting in a complex structure and inconvenient operation. In addition, the semi-circular cover requires multiple bolts and positioning blocks to fix it to the water seal cover, further increasing the complexity of electrode replacement and seriously affecting work efficiency and maintenance convenience. In view of this, we propose a phosphorus furnace electrode sealing device. Utility Model Content

[0005] The purpose of this invention is to provide a phosphorus furnace electrode sealing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The bottom of the water seal cover is provided with a first annular ferrite magnet that is attracted and connected to the second annular ferrite magnet, which facilitates the disassembly and assembly of the water seal cover.

[0008] The top of the water seal cover has a circular hole in the middle for the electrode to pass through. The electrode passes through the circular hole into the electric furnace. A limiting ring is provided at the top of the water seal cover near the circular hole to fix the bottom position of the graphite packing. Graphite packing is filled between the limiting ring and the electrode to seal the circular hole and the gap between the electrode and the sealing element.

[0009] The top of the water seal cover and near the outer edge is provided with a T-shaped limiting tube, which can fix the seal to the water seal cover without the need for screws. The outside of the T-shaped limiting tube is provided with a sealing element for pressing the graphite packing, so that the graphite packing tightly wraps around the outside of the electrode.

[0010] The sealing element includes a first pressure block and a second pressure block hinged to the first pressure block. A first semi-circular pressure groove is formed in the middle of the front side of the first pressure block, and a second semi-circular pressure groove is formed in the middle of the rear side of the second pressure block. The graphite packing is pressed into the first and second semi-circular pressure grooves. A mounting hole is formed on the outer side of the second pressure block near the left end, and a locking bolt is connected to the mounting hole. A threaded groove for threaded connection of the locking bolt is formed on the front side of the first pressure block near the left end. Only one locking bolt needs to be operated to lock or separate the first and second pressure blocks, which facilitates the replacement of electrodes and improves work efficiency.

[0011] Preferably, the bottom of the inner wall of the water seal tank is provided with a plurality of limiting posts arranged in a ring array. The outer walls of the plurality of limiting posts abut against the outer wall of the water seal cover to limit the position of the water seal cover and ensure that the first ring ferrite magnet and the second ring ferrite magnet at the bottom of the water seal cover are effectively attracted.

[0012] Preferably, the outer wall of the water seal cover is provided with an annular dust cover, the bottom of which is in contact with the top of the electric furnace water seal cylinder to prevent dust from entering the water seal groove and ensure the water seal effect.

[0013] Preferably, the bottom of the first pressure block is provided with a first T-shaped groove, and the bottom of the second pressure block is provided with a second T-shaped groove. The T-shaped limiting tube is located in the first T-shaped groove and the second T-shaped groove, so that the sealing element is effectively installed on the top of the water seal cover.

[0014] Preferably, the height of the limiting ring is the same as the height of the T-shaped limiting tube, and the height of the graphite packing is greater than the height of the limiting ring to ensure the sealing effect of the graphite packing.

[0015] Preferably, the inner wall of the first semi-circular pressing groove is provided with a plurality of first protrusions arranged at equal intervals, and the first protrusions press against the outer side of the graphite packing to improve the pressing effect on the graphite packing.

[0016] Preferably, the inner wall of the second semi-circular pressing groove is provided with a plurality of second protrusions arranged at equal intervals. The second protrusions press against the outer side of the graphite packing to improve the pressing effect on the graphite packing and prevent the graphite packing from shifting during use.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The phosphorus furnace electrode sealing device uses an annular ferrite magnet adsorption design. The water seal cover and the electric furnace water seal cylinder are fixed without complex mechanical structures. Installation or disassembly can be completed simply by magnetic adsorption, which significantly reduces the difficulty of operation, makes it easier for staff to quickly replace electrodes or maintain the sealing device, and reduces downtime.

[0019] 2. The phosphorus furnace electrode sealing device uses a T-shaped limiting tube and a groove for the sealing element to achieve a stable connection between the sealing element and the water seal cover without the need for bolt fixing. Combined with the multi-layer compression structure of the graphite packing, it effectively fills the gap between the electrode and the round hole, prevents the leakage of harmful gases, and ensures efficient sealing inside the furnace.

[0020] 3. The sealing device for the phosphorus furnace electrode adopts a hinged pressure block and a single locking bolt design for the sealing component. Only one bolt needs to be operated to lock or separate the pressure block, which simplifies the cumbersome process of traditional multi-bolt fixing, reduces the risk of operational errors, and avoids safety hazards caused by tools falling or parts loosening.

[0021] 4. The phosphorus furnace electrode sealing device features a limiting post and annular dust cover design within the water seal groove. This design not only precisely positions the water seal cover and the magnet adsorption position but also prevents external dust from contaminating the water seal medium, ensuring the stability of the water seal effect. Furthermore, the ferrite magnet has strong corrosion resistance and can be used for a long time in high-temperature and humid environments, reducing the need for frequent replacements due to component damage.

[0043] In this embodiment, the phosphorus furnace electrode sealing device is used by fixing the electric furnace water seal cylinder 1 to the top of the yellow phosphorus electric furnace, injecting an appropriate amount of water into the water seal groove 10 at the top of the electric furnace water seal cylinder 1, and then aligning the first annular ferrite magnet 20 at the bottom of the water seal cover 2 with the second annular ferrite magnet 6 on the inner wall of the water seal groove 10. The water seal cover 2 is quickly installed into the water seal groove 10 by magnetic attraction, and the water seal cover 2 is circumferentially limited by the limiting post 11 to ensure accurate adsorption position. Next, the electrode 3 is inserted into the round hole 22 of the water seal cover 2 and passes through the electric furnace water seal cylinder 1 into the furnace chamber. Graphite packing 4 is filled in the gap between the limiting ring 23 and the electrode 3 so that its bottom fits against the limiting ring 23.
