Abstract
The utility model relates to a nozzle of a bubble generating device used in a flotation column, in particular to a nozzle of an air jet type bubble generating device. The nozzle comprises a nozzle body with the outer wall at the tail end in threaded connection with the inner wall of the gas generator tube body and a round-head-shaped nozzle spray head positioned in the nozzle body, and is characterized in that the axis of a nozzle hole formed in the nozzle spray head is 5-15 degrees to the axis of the gas generator tube body, and the three nozzle holes are symmetrically and uniformly distributed; the shape of the nozzle hole is a straight-through hole with a flaring-cone-shaped opening at the tail part, and the cone angle of the flaring-cone-shaped opening is 90-120 degrees. The utility model discloses a nozzle is equipped with the nozzle bore of a plurality of equipartitions on the nozzle of bubble generator's shower nozzle, and the nozzle bore designs according to the gas dynamics, can produce the bubble that needs on the technology, and the aeration quantity is big, and the bubble can disperse evenly in the flotation column cross-section in very short distance. Compared with the existing air direct injection type bubble generator, the number of the bubble generators in a single flotation column can be reduced, and the height of the flotation column in the existing use can be reduced.
Description
Technical field
The utility model relates to the nozzle of the bubble generator that uses in a kind of flotation column, especially the nozzle of the bubble generator of air injection type.
Background technology
Development along with mineral processing industry, the shared ratio of the refractory ore that grade is low, disseminated grain size is thin, mineral composition is complicated increases day by day, the mineral processing industry is faced with unprecedented challenge, to researching and proposing of ore-dressing technique method, preparation equipment higher requirement.For improving the economic and technical norms of flotation, many mining industry developed country, as Canada, the U.S., Australia etc. will study one after another sight invest once again have that concentration ratio is big, treating capacity is big, investment is little, operating cost is low flotation column, obtained considerable progress at aspects such as basic theory, version, foaming mode and automatic controls.Bubble generator as the research emphasis of COLUMN TECHNOLOGY, in recent years along with relevant development of science and technology, has been obtained very big progress as the most key technology of flotation column always.The air injection type aerator of succeeding in developing in recent years is one of maximum bubble generator of utilization at present, and nozzle is the most critical parts of air injection type aerator.Currently used nozzle is a hemispherical, has nozzle bore above, and inner surface is covered by pottery, is difficult for pollution or obstruction because of the fouling scale, and the life-span is longer.But, the air-flow that the nozzle bore that nozzle is provided with sprays concentrate shape to penetrate because being, the number of the bubble generator that flotation column needs is more, and investment cost is higher, and is evenly distributed in the cross section of flotation column to bubble from the generation of bubble, need long distance, the height of flotation column is increased.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, a kind of number that reduces the bubble generator that every flotation column uses is provided, reduces investment cost, shortens the nozzle of the bubble generator that uses in the flotation column that uses in the flotation column of height of flotation column.
The purpose of this utility model is achieved through the following technical solutions.
The nozzle of the bubble generator that uses in a kind of flotation column, the nozzle body that comprises tail end outer wall and gas generator inboard wall of tube body thread connection, be positioned at the round end shape nozzle shower nozzle of nozzle body, the axis and the gas generator body axis that it is characterized in that the nozzle bore that has on the nozzle shower nozzle are the 5-15 degree, nozzle bore is three, is symmetrical uniform distributions.
The nozzle of the bubble generator that uses in a kind of flotation column of the present utility model, the afterbody that is shaped as of its nozzle bore has the uncovered clear opening of reamer shape, and the cone angle that its reamer is uncovered is the 90-120 degree.
The nozzle of the bubble generator that uses in a kind of flotation column of the present utility model, on the nozzle of the shower nozzle of bubble generator, be provided with a plurality of uniform nozzle bores, nozzle bore designs according to aerodynamics, select suitable distribution angle, can produce the bubble that needs on the technology, aeration quantity is big, and bubble can be uniformly dispersed in the flotation column cross section in very short distance.Compare with used nozzle, not only can reduce the usage quantity of separate unit flotation column bubble generator, but also can reduce this flotation column height in the present use.

The specific embodiment
The nozzle of the bubble generator that uses in a kind of flotation column, the nozzle body 1 that comprises tail end outer wall and gas generator inboard wall of tube body thread connection, be positioned at the round end shape nozzle shower nozzle 2 of nozzle body, the axis and the gas generator body axis that it is characterized in that the nozzle bore 3 that has on the nozzle shower nozzle are the 5-15 degree, nozzle bore is three, is symmetrical uniform distributions.
The nozzle of the bubble generator that uses in a kind of flotation column of the present utility model, the afterbody that is shaped as of its nozzle bore has the uncovered clear opening of reamer shape, and the cone angle that its reamer is uncovered is the 90-120 degree.
During use, the nozzle of the bubble generator that uses in a kind of flotation column of the present utility model is installed in the bubble generator head, bubble generator is installed in the bottom of flotation column, and along the flotation column periphery, nozzle stretches into flotation column inside, remainder is convenient to Operation and Maintenance in the flotation column outside.After gases at high pressure (500KPa-700KPa) enter,, in flotation column, produce the bubble that requires on the technology through the effect of three nozzle bores on the nozzle.Bubble from flotation column bottom by buoyancy function to the motion of flotation column top, the ore pulp that feeds with the flotation column top in motion process is reverse to collide, the purpose mineral just and bubble stick, taken to the discharge of flotation column top by bubble.
The utility model is compared with the flotation column of same specification under the situation that does not reduce the technique of preparing economic indicator, and it is original 1/3 that the quantity of bubble generator can reduce to, and investment cost reduces significantly.Existing flotation column height can reduce 2-3m, reduces factory building height and capital expenditure.
Claims (2)
1. the nozzle of the bubble generator that uses in the flotation column, the nozzle body that comprises tail end outer wall and gas generator inboard wall of tube body thread connection, be positioned at the round end shape nozzle shower nozzle of nozzle body, the axis and the gas generator body axis that it is characterized in that the nozzle bore that has on the nozzle shower nozzle are the 5-15 degree, nozzle bore is three, is symmetrical uniform distributions.
2. the nozzle of the bubble generator that uses in a kind of flotation column according to claim 1 is characterized in that the afterbody that is shaped as of nozzle bore has the uncovered clear opening of reamer shape, and the cone angle that its reamer is uncovered is the 90-120 degree.
