Abstract
The invention relates to a metallurgy boiled furnace baking device, in particular to a plasm type feeding ejection gun of a sulfating baking boiled furnace and belongs to the technical field of metallurgy device. A nozzle 1 is fixed and connected with an out protecting tube 2, the out protecting tube 2, a larynx tube 4, a feed absorbing cavity 5 and a pressure trachea 6 are fixed and connected orderly on a same axes, the feed absorbing cavity 5 is fixed and connected with an ore plasm tube 7 with an inclined angle, the ore plasm tube 7 forms an included angle with the axes, the two ends of an inner feed tube 3 are inserted into the grooves of the nozzle1 and the larynx tube 4 and are freely cooperated, the pressure trachea 6 extends into the feed absorbing cavity 5 and atop point position thereof is on the axes of the included angle of the ore plasm tube 7 and the axes. The invention needs not to pressure the ore plasm tube, the working pressure of the ejection gun is reduced to 0.25 to 0.35MPa from the former 0.65 to 0.75MPa; therefore, the invention reduces the abrasion of the ore plasm to the nozzle, prolongs the service life of the ejection gun; the ejection gun has simple structure and convenient operation and is not easily blocked.
Description
One, technical field
The present invention relates to a kind of metallurgical boiling roaster equipment, particularly a kind of slurry formula feed spray gun of sulfating roasting fluidized bed furnace belongs to technical field of metallurgical equipment.
Two, technical background
In the gold smelting process, generally adopt the fluidized bed furnace sulfating roasting, its feeding manner has two kinds:
A kind of is the wet method charging; A kind of is dry feed.Because when adopting the wet method charging, the fluidized bed furnace smooth operation is easy to control, so the wet method charging generally is used.Slurry type feeding is in described wet method charging again, promptly is Gold Concentrate under Normal Pressure etc. to be mixed with water be made into 60～70% ore pulp, with making the ore deposit pump, passing through the feed spray gun, ore pulp is sprayed into fluidized bed furnace then.Spray gun is the vitals of fluidized bed furnace, and its effect is that ore pulp is effectively atomized, and keeps continuous, stable, the uniform feed of fluidized bed furnace, and the assurance fluidized bed furnace is worked stably.Because the mineralogical composition complexity in the ore pulp, the ratio of mineral is great, hardness is big, even is corrosive, and general spray gun is easy to damage.As the daily handling ability fluidized bed furnace that is 200 tons of Gold Concentrate under Normal Pressure, the spray gun of outsourcing is adopted in wherein three charging spray gun continuous operations simultaneously, spray gun pressure gas operating pressure 0.65～0.75MPa, have only 3～4 days the service life of spray tip, and maximum 6～7 days, and often stop up spray gun.
Three, summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to operate, material is easy to get, it is easy to make, the boiling roasting furnace slurry type low pressure feed spray gun of economy and durability.
The objective of the invention is to be achieved through the following technical solutions:
A kind of slurry type jet gun for boiling baking oven, comprise nozzle 1, outer pillar 2, interior material pipe 3, trunnion 4, suction chamber 5, tracheal pressure 6, ore deposit slurry pipe 7, wherein nozzle 1 is fixedlyed connected with outer pillar 2, outer pillar 2, trunnion 4, suction chamber 5, fixed order connects between the tracheal pressure 6, nozzle 1, outer pillar 2, interior material pipe 3, trunnion 4, suction chamber 5, tracheal pressure 6 is on same axis, fixedly connected with ore deposit slurry pipe 7 bevels in suction chamber 5, ore deposit slurry pipe 7 has angle with above-mentioned axis, interior material pipe 3 two ends are inserted in the groove of nozzle 1 and trunnion 4, freely cooperate, tracheal pressure 6 stretches into 5 inside, suction chamber, vertex position is on the axis at ore deposit slurry pipe 7 and axis angle place;
Said nozzle 1 is an adjustable nozzle;
Above-mentioned ore deposit slurry pipe 7 becomes 30-60 ° of angle with described axis, preferred 45 ° of angles.
Basic principle of the present invention is that the compressed air of tracheal pressure 6 high velocity jet produces negative pressure in suction chamber 5, ore pulp is sucked in the suction chamber 5 from ore deposit slurry pipe 7, atomize at adjustable nozzle 1 place by trunnion 4 and interior material pipe 3, spurt into the fluidizing reactor internal combustion equably.
A kind of slurry type jet gun for boiling baking oven of the present invention does not need to give separately ore deposit slurry pipe pressurization, spray gun pressure gas operating pressure reduces to 0.25～0.35Mpa from 0.65 original～0.75Mpa, reduce ore pulp to nozzle abrasion, prolonged the service life of spray gun; This spray gun structure is simple, and is easy to operate, is not easy to stop up, and when fluidizing reactor is worked it directly inserted in the stove, with its direct taking-up, prevented that the spray gun high temperature sintering from stopping up during blowing out.
Four, description of drawings
Fig. 1: the structural representation of a kind of slurry type jet gun for boiling baking oven of the present invention.
Five, the specific embodiment
Provide specific embodiment below in conjunction with accompanying drawing, be used for the structure of a kind of slurry type jet gun for boiling baking oven of the present invention is described further.
With reference to figure 1, a kind of slurry type jet gun for boiling baking oven comprises nozzle 1, outer pillar 2, interior material pipe 3, trunnion 4, suction chamber 5, tracheal pressure 6, ore deposit slurry pipe 7, and wherein: nozzle 1 adopts with outer pillar 2 and is threaded; Adopt welding between outer pillar 2, trunnion 4, suction chamber 5, tracheal pressure 6, the ore deposit slurry pipe 7; In material pipe 3 two ends be inserted in the groove of nozzle 1 and trunnion 4, freely cooperate, nozzle 1, outer pillar 2, interior material pipe 3, trunnion 4, suction chamber 5, tracheal pressure 6 are on same axis, ore deposit slurry pipe 7 is at 45 with its axis angle, and tracheal pressure 6 stretches into 5 inside, suction chamber, vertex position on ore deposit slurry pipe 7 and 45 ° of angle axis of axis.
