Description

A kind of diving automatic aerator

Technical field

The utility model is related to a kind of oxygen increasing pump, particularly a kind of diving automatic aerator.

Background technology

Oxygen increasing pump, also referred to as air pump, air is pressed into water, and the oxygen allowed in air is fully contacted with water, to reach In allowing partial oxidation to incorporate water, increase the oxygen content of water, it is ensured that the need for water fish class grows.Ornamental fish tank, greatly to fish pond, Use.Its operation principle is：When wheel rotation, due to the effect of centrifugal force, wind vane promotes gas to move out forward, So as to form a series of spiral helicine motions, the air between impeller blade accelerates rotation and by the gas outside the pump housing in the shape of a spiral Body clamp-ons (sucked by air entry) side channel, and after it enters wing passage, gas is compressed, between being then returned to impeller blade again Again speed up rotation.When air along a spiral path pass through impeller and side channel when, each impeller blade increased compression and The degree of acceleration, with the carrying out of rotation, the kinetic energy of gas increases so that further increase along the gas pressure that wing passage passes through Plus.When air reaches the tie point (wing passage narrows in exit) of side channel and drain flange, gas is to be extruded blade discharge The pump housing.

Existing oxygen increasing pump, generally includes motor, the pump housing, rotating shaft and impeller, and rotating shaft connects motor and impeller respectively, and turns Axle is hollow shaft, has the air admission hole and venthole set along rotating shaft radial direction in rotating shaft, and air admission hole is distinguished with venthole With the cavity insertion of spindle central, during work, air enters from air admission hole, and through the cavity in rotating shaft, is finally arranged from venthole Go out, because venthole, air admission hole are axially perpendicular to lumen centerline, so, the flow route of air has two turns, pole Lossy air imbibed quantity so that the oxygenation efficiency of oxygen increasing pump is good；Further, since the limitation of production cost, various power The diameter of machine shaft of oxygen increasing pump be standard, so, the aperture of the cavity in rotating shaft is limited, it is impossible to obtained bigger Aperture, to increase the air capacity in unit area, limits the oxygenation effect of oxygen increasing pump.

The content of the invention

Technical problem to be solved in the utility model is to provide a kind of diving automatic aerator, and it can adjust air duct Space size, to obtain most rational oxygenation amount, realizes optimal oxygenation effect.

In order to solve the above technical problems, a kind of technical solution of diving automatic aerator of the utility model is：

A kind of diving automatic aerator, including motor, housing and impeller, motor housing are fixedly connected with the casing, the arbor of motor Through casing center and the outside of housing is extended to so as to realize be connected with impeller, with cavity in the housing, in housing side Face is provided with air admission hole, and connection stomata is provided with the center of housing bottom；The impeller includes impeller body and is arranged on impeller There are multiple through channels in the ring flange at body top surface center, the impeller body, there is through hole in ring flange center, it is described Through hole and multiple through channel insertions；Extend downwardly that to be provided with annulus raised in housing bottom surface, the annulus it is raised be connected stomata For coaxial, and the raised inner diameter of annulus is more than the aperture of connection stomata, and machinery is set between ring flange and annulus projection Formula oil sealing, the outer wall of mechanical oil sealing inwall raised with annulus respectively, the inwall of ring flange are fitted close, meanwhile, machine The groove floor that the upper end of tool formula oil sealing is formed with annulus projection is fitted close, and lower end is tight with the groove floor that ring flange is formed Close fit；The arbor is passed through and most from the through hole of connection stomata, the centre bore of mechanical oil sealing and ring flange center successively The dowel hole of impeller body bottom is passed through eventually and dowel hole outside is exposed at, and is spirally connected by nut and arbor and is realized arbor, impeller, machine Tool formula oil sealing and housing are fixedly connected, and arbor diameter less than the diameter of connection stomata, mechanical oil sealing centre bore it is straight Footpath and the diameter of through hole, the arbor outer wall and the inwall and through hole that are connected the inwall of stomata, mechanical oil sealing centre bore Inwall between form clearance space；The air admission hole, the cavity of housing, clearance space and the common shape of multiple through channels Into air flow channel.

The impeller includes the impeller body with hollow cavity and the ring flange for being arranged on impeller body end face center, The outer peripheral face of impeller body is evenly equipped with multiple class triangular vanes, and a drift angle of class triangular vane is towards outside impeller body Side, the both sides of drift angle are respectively side A, side B, certain with the through-hole wall away from ring flange in the hollow cavity of the impeller body The periphery of distance is consistent with class triangular vane number and one-to-one many for starting point is evenly equipped with towards impeller body outer peripheral face Individual involute shape water conservancy diversion rib, top surface, the bottom surface of each involute shape water conservancy diversion rib respectively with the top of the hollow cavity of impeller body Face, bottom surface one are fitted, formd between the starting point of the through hole of ring flange and multiple involute shape water conservancy diversion ribs one it is public poly- Water cavity, has been respectively formed a through channel, public polywater chamber and each insertion between two adjacent involute shape water conservancy diversion ribs Passage insertion, through channel is inwardly connected with the through hole of ring flange center, stretch out insertion to two class triangular vanes it Between impeller body outer peripheral face and class triangular vane side A, the upper edge of the side B is respectively equipped with chamfering with lower edge, A wedge angle is formd between two chamferings, rounding is set on wedge angle.

The side B is connected with corresponding involute water conservancy diversion rib, and the track of side B is parabola, the parabola It is the extension of involute water conservancy diversion rib.

What the utility model can reach has the technical effect that：

Compared with prior art, diving automatic aerator of the present utility model, using the side B of parabolic path as impeller Water end (W.E.) face is pushed away, and is respectively provided with chamfering and rounding, this greatly reduces the resistance of side B and water, during operating, motor Load is smaller, and service life is longer；Compared with prior art, diving automatic aerator of the present utility model, in process component, shell The air admission hole of body, the cavity of housing, connection stomata, the centre bore of mechanical oil sealing, the through hole of ring flange and multiple insertions are led to Road can carry out size adjusting according to the actual service condition of client, final real so as to the size for realizing clearance space can adjust Can adjust for existing air inspiration amount, has reached optimal use effect；

Compared with prior art, diving automatic aerator of the present utility model, in impeller operation, side B water flow cuttings, and it is empty When gas flows to the intersection between side B and impeller body from through channel, due to the track of the side B of class triangular vane It is the extension laterally of involute shape water conservancy diversion rib, air naturally can be expelled to impeller outer, air resistance along water flow cutting Power is reduced；In addition, air from air admission hole after entering in housing hollow, it is directly over clearance space and enters multiple insertions Passage is simultaneously finally exhausted in water, and whole circulation passage is smooth, without turning, air loss has been down to minimum.
