Abstract
The invention discloses a hopper sealing cone valve structure. The hopper sealing cone valve structure comprises a sealing flange, a cone valve, a hopper, a protective sleeve, a guide drum, a sealing assembly and a driving cylinder, wherein the cone valve comprises a clamping flange, a sealing ring, a fastener, a cone valve body and a nut; the sealing ring is arranged between the clamping flange and the cone valve body, the clamping flange is fixedly arranged on the cone valve body through the fastener and the cone valve body is in threaded connection with the driving cylinder and are fastened by the nut; the protective sleeve is arranged outside the guide drum and is mounted on the hopper, a material holding opening and a charging opening are formed in the hopper, the sealing flange is arranged at the charging opening and the sealing assembly is arranged at the upper part of the guide drum. The hopper sealing cone valve structure is simple in structure and is convenient to overhaul and replace, the effective volume of the hopper can be increased and meanwhile possibility of material and gas leakage in the vacuum treatment process can be reduced.
Description
Technical field
The present invention relates to field of metallurgy, particularly a kind of a kind of hopper sealing cone valve structure of charging system in the outer a refining unit of vacuum oven.
Background technology
The function of the outer a refining unit of vacuum oven is about in the vacuum environment of 67Pa in absolute pressure to carry out degassed to molten steel, and decarburization, composition adjusts.In order to drop into quantitative alloying constituent in molten steel, above the vacuum chamber of process molten steel, charging system is set, the control that feeds intake of various hopper under carrying out vacuum state.The multiple alloy material that various hopper repeatedly drops into carries out smelting chemical reaction with metallic element to be adjusted in molten steel respectively, the formation inclusion that can float and can the waste gas of dissipation, thus the alloying constituent in guarantee molten steel, produce high quality, the fine work steel of high added value and special steel.
At present, in known vacuum charging hopper, rely on air cylinder driven " del " to seal the open and close controlling of cone valve, carry out atmospheric pressure state and vacuum state in hopper and switch, realize the material feeding in liquid steel refining process and the function that feeds intake.This cone valve sealed structure is enclosed in feeding chamber, and its valve body and protection cylindrical shell considerably reduce the useful volume of hopper, and not easily check and change.After sealing-ring and tongued and grooved flanges crush seal, easily produce the friction along inclined-plane and shear fatigue, and sealing surface area is less.After frequently feeding intake, resistance to air loss is easily caused to decline.
As everyone knows, vacuum metling requires very high to the resistance to air loss of whole device.Cone valve stopping property declines, and atmospheric pressure state and vacuum state switching capability in hopper are weakened, and throughput rate declines.Meanwhile, extend vacuum pump pumpdown time, have impact on the foundation of vacuum tightness in vacuum chamber, reduce efficiency and the quality of vacuum metling.
Summary of the invention
A kind of hopper is the object of the present invention is to provide to seal cone valve structure, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of hopper sealing cone valve structure, comprises tongued and grooved flanges, cone valve, hopper, protection sleeve, guide cylinder, seal assembly and drives cylinder; Described cone valve forms by clamping flange, sealing-ring, fastening piece, cone valve and nut; Described sealing-ring arranges between clamping flange and cone valve, and clamping flange is fixed on cone valve by fastening piece, and cone valve is threaded connection with driving cylinder, and with fastening nuts; Described protection sleeve is arranged on the outside of guide cylinder, and described protection sleeve is arranged on hopper, and described hopper is provided with material receiving port and dog-house, and described tongued and grooved flanges is arranged on dog-house place, and described guide cylinder top is provided with seal assembly.
As the further scheme of the present invention, described cone valve is equilateral triangle structure.
As the further scheme of the present invention, described sealing-ring is Integral elastic sealing-ring, and sealing-ring cross section is rectangle, trim is annular slope.
As the further scheme of the present invention, described hopper is provided with manhole.
As the further scheme of the present invention, the top of described hopper is provided with material receiving port, and the bottom of hopper is provided with dog-house.
Compared with prior art, advantage of the present invention: this hopper sealing cone valve structure, its structure is simple, can increase the useful volume of hopper, easy access and replacing, can reduce the leakage material in vacuum process and gas leak phenomenon simultaneously.
