Description

Technical Field

[0001] This utility model relates to the field of non-ferrous metallurgy, and in particular to a maintenance platform for replacing quartz bottles outside an electric field. Background Technology

[0002] Electrostatic precipitators are essential equipment in smelters. Their function is to remove particulate matter from combustion emissions, thereby significantly reducing the amount of smoke and dust released into the atmosphere. This is a crucial environmental protection device for improving air quality and reducing pollution. The top conical quartz bottle is one of the main insulating components of the electrostatic precipitator, but it is also a vulnerable part. If the conical quartz bottle breaks down or ruptures, it can easily cause a short circuit in the electric field, preventing the electric field from supplying electricity and affecting the dust collection efficiency of the electrostatic precipitator.

[0003] The internal temperature of the electric field can reach over 1200 degrees Celsius. For replacing quartz bottles, work can only begin after the electric field temperature, especially the temperature of the quartz bottle itself, has dropped to a level tolerable for the workers. While the quartz bottle material can withstand high temperatures, it cannot be cooled using water or air cooling methods. Therefore, replacing a single quartz bottle requires at least 12 hours, which is extremely time-consuming in maintenance processes with strict time constraints and can even extend the estimated maintenance time. This results in significant machine downtime and economic losses. Therefore, we propose a maintenance platform for replacing quartz bottles outside the electric field. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art by designing a maintenance platform for replacing quartz bottles outside the electric field.

[0005] To achieve the above objectives, the technical solution of this utility model is a maintenance platform for replacing quartz bottles outside an electric field, comprising an electrostatic precipitator, a quartz bottle, a lifting rod, a cap, a hand-operated hoist, a lifting rope, an operator, a connecting flange, a main beam, threaded holes, lifting lugs, a hook, bolts, and a connecting block. The electrostatic precipitator is characterized by having four lifting rods installed at its top, with the quartz bottle mounted on the upper half of each rod. The bottom of the quartz bottle rests on the top of the electrostatic precipitator. The top of the electrostatic precipitator has four operating holes, each connected to a cap. The lower half of each lifting rod is located inside the electrostatic precipitator, and the lower end of each rod is connected to a main beam.

[0006] Preferably, a connecting flange is fixedly installed above the operating hole, and a connecting flange is also fixedly installed below the sealing cap. The operating hole and the sealing cap are connected by the connecting flange, and the sealing cap is filled with thermal insulation cotton.

[0007] Preferably, the main beam is provided with four lifting lugs, the positions of which correspond to the four operating holes at the top of the electrostatic precipitator.

[0008] Preferably, the lower end of the boom is provided with a groove, the groove portion is provided with a threaded hole, the main beam is provided with four connecting blocks, the connecting blocks are also provided with threaded holes, and the boom is aligned with the threaded hole in the groove portion and the threaded hole on the connecting block and then connected by bolts.

[0010] Beneficial effects:

[0011] This utility model provides a maintenance platform for replacing quartz bottles outside an electric field, which has the following advantages: Through its structural design, this device uses a main beam to build a new working platform. When it is necessary to replace the quartz bottle, it is only necessary to cool down the main beam, and then the worker can disconnect the threaded connection between the main beam and the hanging rod to replace the hanging rod and the quartz bottle together. This greatly reduces the cooling time, speeds up the replacement efficiency, and avoids the potential hazards caused by workers entering the electric field. Attached Figure Description

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "set / set up," "sleeve," "connection," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a maintenance platform for replacing quartz bottles outside an electric field, comprising an electrostatic precipitator 1, a quartz bottle 2, lifting rods 3, caps 4, a hand-operated hoist 5, a lifting rope 6, an operator 7, a connecting flange 8, a main beam 9, threaded holes 10, lifting lugs 11, hooks 12, bolts 13, and connecting blocks 14. Four lifting rods 3 are installed at the top of the electrostatic precipitator 1. The upper half of each lifting rod 3 is fitted with a quartz bottle 2, and the bottom of the quartz bottle 2 rests on the top of the electrostatic precipitator 1. Four operating holes 7 are provided at the top of the electrostatic precipitator 1, and caps 4 are connected to the operating holes 7. The lower half of each lifting rod 3 is located inside the electrostatic precipitator 1, and the lower end of each lifting rod 3 is connected to the main beam 9. A connecting flange 8 is fixedly installed above each operating hole 7, and a connecting flange 8 is also fixedly installed below each cap 4. The operating holes 7 and caps 4 are connected by the connecting flange 8. The caps 4 are filled with insulating cotton for further sealing and to reduce system air leakage. The main beam 9 is equipped with four lifting lugs 11, which correspond to the four operating holes 7 at the top of the electrostatic precipitator 1, facilitating the connection of the hook 12 through the operating holes 7 to the lifting lugs 11. The lower end of the lifting rod 3 has a groove with threaded holes 10. The main beam 9 is equipped with four connecting blocks 14, each with threaded holes 10. The lifting rod 3 aligns with the threaded holes 10 in the groove and the connecting blocks 14, then is connected by bolts 13. A lifting rope 6 can pass through the operating holes 7. The lifting rope 6 is installed inside a hand-operated hoist 5, which is mounted on the top of the factory building. One end of the lifting rope 6 is connected to a hook 12.

[0021] In this implementation plan:

[0022] When it is necessary to replace the quartz bottle 2, shut down the electrostatic precipitator 1 system, and then cool down the main beam 9. When the temperature drops to a level where workers can enter, first disconnect the connecting flange 8 between the operating hole 7 and the cap 4 next to the quartz bottle 2 to be replaced, remove the cap 4, and then open the operating hole 7. Then install the hand chain hoist 5 at the corresponding position on the top of the plant, and then put the hoisting rope 6 with the hook 12 end into the operating hole 7, so that the hook 12 is connected to the lifting lug 11. Then tighten the other end of the hoisting rope 6 to ensure that the main beam 9 can still maintain balance after the connection between the lifting rod 3 and the main beam 9 is disconnected. Then the worker reaches the connection between the main beam 9 and the lifting rod 3, removes the bolt 13, and disconnects the main beam 9 from the lifting rod 3, thus completing the replacement of the quartz bottle 2 and the lifting rod 3. After the replacement is completed, remove the hand chain hoist 5 and the hoisting rope 6, and use the connecting flange 8 to seal the connection between the cap 4 and the operating hole 7.
