Besides the function of gas-liquid contacting and mixing of the bubble generator with a single nozzle, the utility model is characterized in that: the function of collision and strengthening among the liquids enables gas to be supplied adequately and well mixed; a flotation equipment is only provided with a multiinjector bubble generator to realize compact structure and low cost; the external and parallel connection branched pipe is needless, the efficiency of bubble generation is superior to a plurality of bubble generator with a single nozzle and the structure is equivalent to a set of the bubble generator with a single nozzle, thus the multiinjector bubble generator is more efficient. The utility model has the advantages of compact structure, convenient installation and maintenance, low cost, and wide practicability.
Description
Technical field
The utility model relates to a kind of multiinjector bubble generator, is particularly useful for the aerating device of coal slime flotation post flotation.
Background technology
The bubble generator that uses in the flotation has multiple, wherein the jetting type bubble generator because of its be difficult for to stop up, reliability and durability and can satisfy the bubble diameter requirement and obtained to use widely.But because the jetting type bubble generator that uses is single nozzle-type at present, when nozzle diameter is big, gas, liquid contact effect is bad, therefore need to be installed in parallel the bubble generator of many less nozzle diameters on the table flotation optional equipment, and the bubble generator that these are installed in parallel input needs corresponding parallel branch with output pipe, it is loosely organized, and the manufacturing cost height is installed and the maintenance trouble.For this reason, generally hold concurrently simultaneously chin or cheek gas, liquid contact effect and manufacturing cost and installation maintenance convenience in the reality, because two kinds of needs are conflicting, so often attend to one thing and lose sight of another.
Summary of the invention
Technical problem: the purpose of this utility model provides a kind of compact conformation, and cost is low, and multiinjector bubble generator is easily installed and overhauled to the efficient height.
Technical scheme: a kind of multiinjector bubble generator of the utility model, it comprises feed pipe, the gas-liquid mixed chamber, air supply pipe, trunnion and anemostat are provided with deflector along the junction perpendicular to fluid flow direction and gas-liquid mixed chamber in feed pipe, deflector is provided with a plurality of nozzles; The indoor annular air supply chamber that is surrounded by bucket-shaped conduit that is provided with of gas-liquid mixed, bucket-shaped conduit is provided with a plurality of air admission holes.
A kind of multiinjector bubble generator of the utility model, the described deflector that is provided with a plurality of nozzles can be a butterfly plate, also can be that arc or circle are dull and stereotyped; The described nozzle that is located at deflector is for conical, and big mouthful outwards, and osculum is inside.
Beneficial effect: a kind of multiinjector bubble generator of the utility model, be best suited for the aerating device of coal slime flotation post flotation, adopt a plurality of nozzles and annular air supply chamber, except that the gas with single-nozzle bubble generator, liquid contact and mixed function and effect, also has the collision enforcement effect between each line body, air feed is evenly abundant, can make contour direction and the generatrix direction all evenly supply of gas along gas, liquid contact chamber, guarantees enough aeration quantitys.One table flotation optional equipment only need dispose a multiinjector bubble generator and get final product, thereby compact conformation, low cost of manufacture, need not external parallel branch pipeline, the function of gassing and effect are better than a plurality of single injector bubble generators, structure is equivalent to the set of a plurality of single injector bubble generators, thereby more efficient, and its compact conformation, installation and maintenance are convenient, low cost of manufacture has practicality widely.
Description of drawings
Accompanying drawing is a kind of multiinjector bubble generator of the utility model structure chart.
Among the figure: the 1-deflector; The 2-nozzle; The 3-feed pipe; The 4-sealing gasket; 5-bolt group; 6-gas-liquid mixed chamber; 7-annular air supply chamber; The 8-air supply pipe; The 9-trunnion; The 10-anemostat.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
A kind of multiinjector bubble generator of the utility model mainly contains deflector 1, feed pipe 3, gas-liquid and connects mixing chamber 6, annular air supply chamber 7, air supply pipe 8, trunnion 9 and anemostat 10 and form.Plate deflector 1 is located at the inlet junction that feed pipe 3 and gas-liquid connect mixing chamber 6, the junction that feed pipe 3 and gas-liquid connect mixing chamber 6 is provided with sealing gasket 4 and is fixed and is the bolt group 5 of one, deflector 1 is a butterfly plate, this dish plate is being met stream side projection, in back of the body stream side depression, can realize that each beam fluid can both shrink near the usage range that is pooled to the bubble generator axis of symmetry, can make dish plate bear the bigger hydrostatic pressure from feed pipe 3 again.Dish plate is permanent part, and the nozzle 2 of uniform setting on it is a consumable accessory, for ease of the independent part that changes.A plurality of nozzles 2 on the butterfly plate are conical, big mouthful outwards, osculum is inside, it matches with each conical bore on the butterfly plate, be fitted in respectively in each perforate of dish plate, for preventing nozzle 2 slippage from the dish plate perforate in use, nozzle 2 is located on the butterfly plate along jet directions, nozzle 2 has boss meeting the stream side.Be provided with the annular air supply chamber 7 that is surrounded by bucket-shaped conduit in the gas-liquid mixed chamber 6, bucket-shaped conduit is provided with a plurality of air admission holes.Feed pipe 3 is connected the outlet of flotation feed pump by pipeline with control valve, annular air supply pipe 8 is connect atmosphere (air-breathing) or connect air blast (calming the anger) by pipeline and control valve, the bubble distributor that anemostat 10 connects in the floatation equipments.When from the flotation feed pump the mud jacking body is arranged through feed pipe 3 and nozzle 2 time, be the multi beam jet-like and enter gas-liquid contact chamber 6, and crowding and enter trunnion 9.Because the viscous of jet is carried effect secretly, make the interior gas of gas-liquid contact chamber 6 be brought into trunnion 9 together, and be sheared and be broken into minute bubbles, be evenly distributed in the slurry.The pressurization of fluid in trunnion 9 makes the portion gas that is distributed in the slurry be absorbed by liquid.Gas, liquid, solid three-phase fluid release of pressure gradually in anemostat 10 makes the portion gas that is absorbed by liquid separate out microbubble.Micro-bubble and solid particle are the gas, liquid, solid three-phase stream that decentralized photo, liquid be continuous phase and finally discharge from the big end of anemostat 10.Because deflector 1 axis of symmetry overlaps with the axis of symmetry of trunnion 9, no matter which kind of shape deflector 1 adopts, can make each emitted line body of a plurality of nozzles, contraction is pooled near the usage range of the bubble generator axis of symmetry, with the diameter that guarantees trunnion 9 always less than the feed pipe diameter, when guaranteeing that simultaneously each line body moves in gas-liquid contact chamber 6, can well contact, mix with gas.
