Abstract
The invention relates to a pump shaft for a cavitation air floatation machine. The pump shaft comprises a pump shaft body. A motor mounting shaft is arranged at one end of the pump shaft body. An impeller mounting shaft is arranged at the other end of the pump shaft body. A plurality of fixed grooves are formed in the position, close to the pump shaft body, of the impeller mounting shaft and fixedly connected with a dual-end-face sealing device. By means of the dual-end-face sealing device, the connecting part of the pump shaft and an impeller shaft is sealed tightly, water is not liable to enter, and the service life of the air floatation machine is prolonged; the motor mounting shaft and a coupler are fixedly connected through fixed holes; and by means of the design of the fixed holes, mounting grooves and mounting clamp protrusions, the connecting part of the pump shaft and a connecting shaft is effectively prevented from being broken, and the pump shaft and the connecting shaft are connected more tightly.
Description
Technical field
The invention belongs to air floatation machine technical field, specifically, relate to a kind of pump shaft for air flotation turbo.
Background technique
At present, contain the more former water water body of sand except some and contain except the heavier sewage of mechanical admixture, the water quality that major part need process is all the suspended particulate of light weight.Such as: the fluviatic algae of lake, reservoir and part; Plant residues and tiny colloidal impurity; The dye granule of dyeing; The short fibre of papermaking, chemical fibre industry; Oil refining, the oil of chemical industry and the droplet of organic solvent; Plating and pickling waste waters in heavy metal ion; Electrophoretic paint waste water etc.; All that proportion is very close to the light granules of water.For these former water, if continue to use traditional intermediate processing, effect is inevitable very poor, and especially in the winter time under cryogenic conditions, because coagulation and hydraulics become bad, treatment effect is more difficult to ensure card.
Can imagine, be difficult to the wadding grain precipitated, make it sink obstinately, certainly will get twice the result with half the effort, it would be better to and make the best use of the situation, bubble is imported artificially in water body, make it adhere on wadding grain, thus reduce the global density of wadding grain significantly, and borrow the speed that bubble rises, make it float by force, realize solid-liquid separation fast with this.In this sense, the appearance of air flotation technology, be the revolution to settling methods, it has opened up the frontier of solid, liquid stripping technique.
Air flotation turbo utilizes the high speed rotating of loose gas impeller bottom air delivery pipe in water, form a region of no pressure, air on liquid level is by aerator input water, fill a vacuum, micro gas-bubble produces thereupon and also rises to the water surface to screw type, and the oxygen in air also dissolves in water thereupon.
Air flotation turbo is by pump shaft connecting motor and impeller shaft, and pump shaft is connected with motor by coupling, but, pump shaft and impeller shaft joint are due to sealing problem, easily intake after during long-time use, reduce the working life of air floatation machine, easily rupture in pump shaft and coupling joint simultaneously.
Summary of the invention
Instant invention overcomes shortcoming of the prior art, provide a kind of pump shaft for air flotation turbo, its pump shaft and the sealing of impeller shaft joint closely, are not easily intake, are extended the working life of air floatation machine.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of pump shaft for air flotation turbo, comprise pump shaft main body, described pump shaft main body one end is provided with motor installation shaft, the described pump shaft main body the other end is provided with impeller installation shaft, described impeller installation shaft is provided with some fixed grooves near the position of described pump shaft main body, the affixed double seals device of described fixed groove.
Further, described motor installation shaft is provided with some installation grooves and installs card convex near the position of described pump shaft main body, and an installation card convex diameter near described pump shaft main body is greater than described in other installs card convex.
Further, described motor installation shaft is provided with the fixed hole of the vertical described motor installation shaft axis of three rows, row's fixed hole near described motor installation shaft end and the row's fixed hole near described pump shaft main body one end are four fixed holes of annular array, and middle row's fixed hole is six fixed holes of annular array.
Further, described double seals device comprises left rotating ring and right rotating ring, is provided with spring between described left rotating ring and right rotating ring.
Further, described installation card convex is three.
Further, described fixed groove is two.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of pump shaft for air flotation turbo of the present invention, double seals device makes pump shaft and the sealing of impeller shaft joint closely, not easily intake, extend the working life of air floatation machine, by fixed hole and coupling affixed, the design of fixed hole, installation groove and installation card convex, effectively prevents pump shaft and the fracture of coupling shaft link position, makes both connect tightr.
