Description

The feeding device of Gas-making Furnace

Technical field

The utility model relates to a kind of feeding device of Gas-making Furnace, particularly relates to the feeding device of the Gas-making Furnace of a kind of pair of casing and two ball valves.

Background technology

The feeding device of existing Gas-making Furnace, comprise that a reinforced casing, reinforced lower box have opening to fixedly connected with the charging opening of Gas-making Furnace, opening part is equipped with valve seat, is complementary with taper valve core, taper valve core and valve rod are directly used nut screwing clamping, by valve rod and cylinder interlock.Cylinder piston drives control stick to be changed the circumferential motion of control stick moving up and down of valve rod into and drives taper valve core through axle, lifting rod, connecting rod, makes closure of openings or unlatching.Taper valve core and seat material are carbon steel.

The feeding device of above-mentioned Gas-making Furnace, owing to have only a miter valve, when its taper valve core was opened reinforced (as coal or coke), the gas in the Gas-making Furnace will overflow; Taper valve core and stem material are carbon steel in addition, and any processing is not done on the surface, thereby easy to wear; Taper valve core and valve rod are directly used nut screwing clamping, thus there is not regulating effect, when taper valve core is crooked, easily gas leakage.

Summary of the invention

The purpose of this utility model is to provide the Gas-making Furnace feeding device of a kind of pair of casing and two ball valves, and this feeding device can prevent the gas leak in the Gas-making Furnace when reinforced, safe and reliable.

The utility model is achieved in that the feeding device of this Gas-making Furnace comprises a reinforced casing, reinforced lower box lower opening is fixedlyed connected with the charging opening of Gas-making Furnace, lower opening is equipped with lower valve base, and lower valve base and bottom spool are complementary, and bottom spool is by lower valve rod and the interlock of liquid (gas) cylinder pressure.The top of reinforced phase body connects the casing of getting the raw materials ready by a communicating pipe, and the bottom of the casing of getting the raw materials ready is provided with upper shed.Be characterized in: the upper valve base and the upper valve core on upper shed top are complementary, and upper valve core is by upper valve rod and the interlock of last liquid (gas) cylinder pressure, and charging opening is arranged at the casing top of getting the raw materials ready.Upper valve core is a spherical valve core, and upper valve core, upper valve rod and last liquid (gas) cylinder pressure are on the same axis, and there is a liner at upper valve rod [11] middle part.Bottom spool is a spherical valve core, and bottom spool, lower valve rod and following liquid (gas) cylinder pressure are on the same axis, and there is a liner at the lower valve rod middle part.The unlatching of spool and to close be press to promote the operation of liquid (gas) cylinder pressure piston by liquid (gas) to drive spool through liner by valve rod and move up and down.

The lower opening of reinforced lower box of the present utility model is equipped with down blowing device, and its structure is a ring pipe, the radial hole that distributing on the ring pipe, and ring pipe is communicated with compressed gas source.

Blowing device is equipped with in upper shed place of the lower box of getting the raw materials ready of the present utility model, and its structure is a ring pipe, the radial hole that distributing on the ring pipe, and ring pipe is communicated with compressed gas source.In the time of bottom spool or upper valve core unlatching, compressed gas is just by descending blowing device or last blowing device to spray at a high speed, can remove the solid particulate on the trim, make trim cleaning between spool, valve seat or upper valve core, the upper valve base, the air curtain of Xing Chenging can be isolated the gas leak in the Gas-making Furnace again simultaneously.

The working process of this Gas-making Furnace is as follows: 1, close down ball valve and upper ball valve.2, the material (as coal or coke) through measuring adds from the charging opening on the casing top of getting the raw materials ready.3, open upper valve core, open simultaneously and go up blowing device, the material in the casing of getting the raw materials ready is in being discharged into reinforced casing communicating pipe.4, close upper valve core, close again and close blowing device.5, open bottom spool the intravital material of charging box is discharged in the Gas-making Furnace, open blowing device down simultaneously.6, close bottom spool, close down blowing device again, whole reinforced process to Gas-making Furnace is finished.The utility model has at least a ball valve to be in closing condition in reinforced process, thereby has guaranteed the closure of this feeding device, has solved original technology when reinforced, the defective that the gas making furnace gas can overflow.

The surface in contact of bottom spool of the present utility model and lower valve base, pile-up welding hard alloy on the surface in contact of upper valve base and upper valve core, thereby the reliability and the work-ing life of having improved trim.

Bottom spool of the present utility model is an adjustable structure, and spherical surface body is arranged at the lower valve rod bottom, the bottom spool joint nut, and the nut lower end is taper, is complementary with the spherical surface body of lower valve rod.Upper valve core also is an adjustable structure, and its structure is identical with above-mentioned bottom spool adjustable structure.

Between lower valve rod of the present utility model and the nut O-ring seals is arranged, be with corrugated tube between lower valve rod and the bottom spool, O-ring seals is also arranged between upper valve rod and the corresponding nut, also be with corrugated tube between upper valve rod and the upper valve core.The effect of O-ring seals and corrugated tube is to prevent that dust from entering in the spool adjustable structure.

The utility model has following advantage compared with prior art: owing to the feeding device of this Gas-making Furnace, adopts the structure of upper and lower two tanks and upper and lower two spherical valves, when reinforced, can prevent effectively that the gas in the stove from overflowing, and safe and reliable.The utility model can be pressed button by hand and operate, and also can control automatically.Adopt the utility model can make Gas-making Furnace realize that not blowing out is reinforced, thereby improve the throughput of Gas-making Furnace, and improved workman's operating environment.
