Technical Field

[0001] The utility model relates to the field of electrode sealing, in particular to a corrosion-resistant electrode water seal sealing structure. Background Art

[0002] Yellow phosphorus is a multi-purpose basic industrial raw material, which is widely used in fertilizers, food, medicine and pesticides. During the electric furnace production process of yellow phosphorus, a large amount of phosphorus vapor will be generated. If these phosphorus vapors are not controlled and float out of the electric furnace, it will not only reduce the phosphorus production, but also cause a lot of damage to the surrounding environment. Therefore, when using the electric furnace for production, an electrode water seal sealing structure is required to seal the electric furnace.

[0003] In the existing technology, for example, patent application No. "201420613358.7" proposes an integral sealing device for an electric furnace electrode and a water seal structure, which uses a graphite packing as a sealing medium. The graphite packing and the electrode form a fixed integral structure. The electrode is sealed and connected to the water seal cover through the graphite packing. Isolation water is provided between the water seal box and the water seal cover to isolate the phosphorus vapor in the furnace from the outside world.

[0004] Although the current electrode water seal sealing structure can isolate the phosphorus vapor in the furnace from the outside world, after the phosphorus vapor comes into contact with the isolation water, a part of the phosphorus vapor will react with the isolation water to produce phosphoric acid; phosphoric acid is corrosive and will gradually corrode the sealing device. Long-term use will reduce the sealing performance of the sealing device. Utility Model Content

[0007] As an improvement, the electrode device includes an electrode passing through a water seal cover and a water seal box and electrode clamps located on both sides of the electrode, the electrode clamps are connected by a bolt structure, and the electrode clamps are connected to the electrode by body contact.

[0008] As an improvement, a sealing groove corresponding to the graphite packing is provided above the water seal cover, the electrode passes through the graphite packing, and the water seal cover is connected to the electrode clamp by a bolt structure.

[0009] As an improvement, the graphite packing will deform when subjected to force, and the electrode is sealed and connected to the sealing groove through the deformation of the graphite packing.

[0010] As an improvement, the water exchange device includes a water exchange pipe located below the side of the water seal box, a corrosion-resistant rubber plug that seals the water exchange pipe, and a water-leakage-proof cover, and the corrosion-resistant rubber plug passes through a corrosion-resistant rubber plate sleeve located on the inner wall of the water seal box.

[0011] As an improvement, a corresponding water exchange pipe rubber sleeve is provided inside the water exchange pipe, and the anti-leakage cover is connected to the water exchange pipe through a bolt structure.

[0012] Compared with the prior art, the utility model has the following advantages: the structure copes with the corrosion of phosphoric acid through the corrosion-resistant rubber sheet sleeves on the inner wall of the water seal box and the side wall of the water seal cover, and the water changing device below the water seal box replaces the phosphoric acid in the isolation water with clean water, and the phosphoric acid adsorbed on the corrosion-resistant rubber sheet sleeve is also flushed out, thereby reducing the phosphoric acid content in the water seal box.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] As the instruction manual Figure 1 , 2As shown in Figure 4, it includes a water seal box 1, and a corresponding water seal cover 2 and an electrode device 3 are sequentially arranged on the top of the water seal box 1, and the electrode device 3 passes through the water seal cover 2 and the water seal box 1. A water changing device 4 is arranged on the side of the water seal box 1, and the water changing device 4 includes a water changing pipe 41 located at the lower side of the water seal box 1, a corrosion-resistant rubber plug 42 sealing the water changing pipe 41, and a water leakage-proof cover 43. The corrosion-resistant rubber plug 42 passes through the corrosion-resistant rubber sheet sleeve 11 located on the inner wall of the water seal box 1, and a corresponding water changing pipe rubber sleeve 411 is arranged inside the water changing pipe 41. The water leakage-proof cover 43 is connected to the water changing pipe 41 through a bolt structure, and the corrosion of the pipe by phosphoric acid water is reduced by the water changing pipe rubber sleeve 411. The corrosion-resistant rubber sheet sleeve 11 is connected to the corrosion-resistant rubber plug 42 through the body contact, so that the isolated water will not leak, and the water leakage-proof cover 43 is blocked on the outside of the corrosion-resistant rubber plug 42 to prevent the water pressure from pushing the corrosion-resistant rubber plug 42 out of the through hole of the corrosion-resistant rubber sheet sleeve 11.

[0020] As the instruction manual Figure 1 , 3 As shown in , 4, the water seal cover 2 is sealed and connected to the electrode device 3 through a graphite packing 21, the inner wall of the water seal box 1 and the side wall of the water seal cover 2 are provided with a corrosion-resistant rubber sheet sleeve 11, the electrode device 3 includes an electrode 31 passing through the water seal cover 2 and the water seal box 1 and an electrode clamp 32 located on both sides of the electrode 31, the electrode clamp 32 is connected through a bolt structure, the electrode clamp 32 and the electrode 31 are connected through body contact, a sealing groove 22 corresponding to the graphite packing 21 is provided above the water seal cover 2, the electrode 31 passes through the graphite packing 21, the water seal cover 2 and the electrode clamp 32 are connected through a bolt structure, the graphite packing 21 will be deformed when subjected to force, the electrode 31 is sealed and connected to the sealing groove 22 through the force deformation of the graphite packing 21, and the graphite packing 21 between the electrode clamp 32 and the water seal cover 2 is deformed by adjusting the screws between the electrode clamp 32 and the outside of the water seal cover 2. The deformed graphite packing 21 seals the electrode 31 and the sealing groove 22 to prevent phosphorus vapor from floating out. The inner wall of the water seal box 1 and the side wall of the water seal cover 2 are both covered with a corrosion-resistant rubber sheet cover 11, thereby preventing the inner wall of the water seal box 1 and the side wall of the water seal cover 2 from directly contacting the isolation water, thereby reducing the corrosion of the inner wall of the water seal box 1 and the side wall of the water seal cover 2 by phosphoric acid.

[0021] During the specific implementation of the utility model, the electrode 31 is placed between the two electrode chucks 32, and the electrode chucks 32 are fixed and locked with screws; the electrode 31 is inserted into the inner ring of the graphite packing 21, and the outer ring of the graphite packing 21 is placed in the sealing groove 22 above the water seal cover 2, and the screw hole on the bottom surface of the electrode chuck 32 is aligned with the screw hole above the water seal cover 2, and the screw is used to lock. During the locking process, the graphite packing 21 is subjected to the forces from the upper and lower sides of the water seal cover 2 and the electrode chuck 32, and the graphite packing 21 is deformed to the left and right, and the electrode 31 and the graphite packing 21 are completely sealed, and the water seal cover 2 and the electrode chuck 32 are also sealed during the force process (the graphite packing 21 has high heat resistance). The invention relates to a water seal cover 2 and a water seal box 1. The water seal cover 2 and the water seal box 1 have corresponding corrosion-resistant rubber sheet sleeves 11, which can withstand the steam temperature in the furnace; the outer side of the isolation plate below the water seal cover 2 and the inner wall of the water seal box 1 are covered with corresponding corrosion-resistant rubber sheet sleeves 11 to prevent phosphoric acid from directly contacting the water seal cover 2 and the water seal box 1; the bottom surface of the corrosion-resistant rubber sheet sleeve 3 of the water seal box 1 is provided with rubber holes corresponding to the corrosion-resistant rubber plugs 42; the water exchange pipe rubber sleeve 411 is covered on the inner wall of the water exchange pipe 41; the corrosion-resistant rubber plug 42 is inserted into the water exchange pipe rubber sleeve 411; the anti-leakage cover 43 is screwed on the water outlet of the water exchange pipe 41; the assembled water seal cover 2 is placed in the water seal box 1, and the corrosion-resistant rubber sheet sleeve 11 on the outer side of the water seal cover 2 is located between the corrosion-resistant rubber sheet sleeve cavities of the water seal box 1.

[0022] When in use, the device is placed at the gas drifting outlet of the yellow phosphorus furnace, and isolation water is added from the open port of the water seal box 1. The isolation water in the water seal box 1 isolates the phosphorus vapor drifting out of the yellow phosphorus furnace. The phosphoric acid generated by the phosphorus vapor and the isolation water has a very low erosion on the corrosion-resistant rubber sheet sleeve 3. Because the inner wall of the water seal box 1 and the side wall of the water seal cover 2 are both covered with corrosion-resistant rubber sheet sleeves 11, the corrosion of phosphoric acid on the inner wall of the water seal box 1 and the side wall of the water seal cover 2 will be greatly reduced. The phosphoric acid water is exchanged through the water exchange pipe 41 at regular intervals. When changing the water, open the anti-leakage cover 43 and pull out the corrosion-resistant rubber plug 42. The phosphoric acid water will flow out under the action of gravity. In the process of the phosphoric acid water flowing out, add water from the open top of the water seal box 1 to flush it, so that the phosphoric acid adhering to the corrosion-resistant rubber sheet sleeve 11 is flushed down to reduce the phosphorus content inside. Finally, the corrosion-resistant rubber plug 42 is inserted into the water change pipe 41, and the top of the corrosion-resistant rubber plug 42 is sealed and connected to the drain port on the corrosion-resistant rubber sheet sleeve 11. Then add new isolation water and use it normally.

[0023] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
