Description

TECHNICAL FIELD

[0001] The present application relates to the connection of high-pressure oil pipes, and a quick connection device which is convenient to disassemble and assemble, and is particularly used in the connection of high-pressure oil pipes of the electrode system of a Kivcet furnace for lead smelting. BACKGROUND

[0002] The Kivcet direct lead smelting technology is an advanced lead smelting technology in the world, and the unique feature of the technology is that production is carried out in one device, and materials are rapidly reacted in a reaction tower through concentrate nozzles to produce a melt, and the melt enters an electric furnace area through coke under the reaction tower to further undergo bath smelting. The heat required for the bath smelting is from the electrode system of the electric furnace. The electric furnace electrode system is the core equipment of the Kivcet furnace, and the main function is to convert electric energy into heat energy through three-phase graphite electrodes, and further separate slag and lead through bath smelting, and heat the melt in the electric heating area through the conversion of electric energy into heat energy to maintain the temperature of the melt in the electric heating area. The hydraulic system is an important component of the electrode system, and mainly includes a hydraulic station, a solenoid valve group, an energy accumulator, high-pressure oil pipes, and an execution oil cylinder. Among them, 18 stainless steel high-pressure oil pipes are used, and an insulating pad needs to be installed between each stainless steel high-pressure oil pipe and an operating end oil pipe to prevent electrode leakage from endangering the personal safety of post personnel.

[0003] In the prior art, the insulating structure between the stainless steel high-pressure oil pipe and the operating end oil pipe is as follows: flanges are respectively installed at the ends of the stainless steel high-pressure oil pipe and the operating end oil pipe, and then an insulating pad is used to realize insulation between the flanges. However, this installation technology has the following disadvantages:

[0004] (1) Two flanges press the insulating pad through four M8 bolts, but the sealing property is difficult to guarantee;

[0005] (2) The insulating pad is in contact with the external environment, is subjected to high-temperature radiation and flue gas corrosion, and has a very fast aging speed, so that the service life is greatly reduced. Once the insulating pad is punctured, the electrode has a risk of leakage;

[0006] (3) The hydraulic system has high pressure, and the aging of the insulating pad easily causes hydraulic oil leakage, which easily causes a fire. SUMMARY

[0007] In view of this, the present application provides a safe and reliable quick connector structure.
