Application number CN201320558889.6, a kind of combined type plug-flow of patent name, which is stirred in aerator, have developed a kind of collection Aeration and agitating function in one equipment, using in various plug-flow aeration systems, can improve be aerated and mixing effect, still This aerator operates underaction, and adjustment aerator position step is relatively complicated, can not meet all kinds of water levels and higher It is required that purification of water quality.

Utility model content

The purpose of this utility model is that, for adjusting aerator position difficulty in the prior art, all kinds of water levels can not be met And requirements at the higher level purification of water quality the problem of, it is intended to increase a kind of aerator adjustment angle and mechanism of lifting of allowing.

The utility model is that solve above-mentioned technical problem by following technical proposals：

A kind of plug-flow stirs aerator, and it includes air blower, flexible pipe, motor and outer tube, and the air blower passes through flexible pipe It is connected to the air inlet of outer tube upper end, it is characterised in that the air blower bottom is provided with controller, under the motor Portion is provided with clip, and the clip both sides symmetrically extend internally provided with projection piece, and the projection piece is with being symmetricly set under motor Fixture on the outside of portion matches, and the outside of the clip and the outer end of expansion link connect, and the inner end of the expansion link and work are flat The elevating mechanism connection of platform side, the expansion link are set diagonally downward from outer end to inner end, perpendicular to workbench side also Provided with fix bar, the fix bar is provided with pulley groove, and the outer end of the expansion link is flexibly connected by pulley with fix bar, described Pulley is flexibly connected with controller by rope, and the elevating mechanism is flexibly connected with controller by rope.

Further, the arbor of the motor is socketed on drive shaft by shaft coupling and driving axis connection, the outer tube Outside, the tail end of the outer tube is sequentially provided with agitating paddle and annular blade.

Further, the agitating paddle is swept-back agitating paddle.

The utility model has the advantage of：Combined type plug-flow stirring aerator integrates aeration performance and agitating function, Have the characteristics that oxygen-transfer efficiency is high, plug-flow distance is remote, stirring scope is wide；Pulley lifts, aerator angle and height in water body It is adjustable, contribute to fully quick oxygenation, it is more convenient to operate；Rabbling mechanism uses swept-back blade, reduces rub at work Wipe power loss, make water flow velocity faster, energy loss it is smaller.

Embodiment

With reference to embodiment and accompanying drawing, the utility model is described in further detail, but reality of the present utility model The mode of applying is not limited only to this.

A kind of plug-flow stirs aerator, and as depicted in figs. 1 and 2, it includes air blower 1, flexible pipe 7, motor 3 and outer tube 8, The air blower 1 is arranged on the top of workbench 19, and the air blower 1 is connected to the air inlet of the upper end of outer tube 8 by flexible pipe 7 Mouthful, it is characterised in that the bottom of air blower 1 is provided with controller 2；

As shown in Figure 1 and Figure 4, clip 4 is provided with around the bottom of the motor 3, the both sides of clip 4 are symmetrically inwardly prolonged Stretch and be provided with projection piece 5, the projection piece 5 matches with being symmetricly set on the fixture 6 of the lower outside of motor 3, locking hoop 4 After fixing bolt, projection piece 5 is embedded in the cell body of fixture 6, ensures that motor 3 will not fall off, as shown in figure 3, the clip 4 Outside be connected with the outer end of expansion link 11, the elevating mechanism 12 of the inner end and the side of workbench 19 of the expansion link 11 connects Connect, the expansion link 11 is set diagonally downward from outer end to inner end, and fix bar 13, institute are additionally provided with perpendicular to workbench side 19 State fix bar 13 and be provided with pulley groove 14, the outer end of the expansion link 11 is flexibly connected by pulley 15 with fix bar 13, the cunning Wheel 15 is flexibly connected with controller 2 by rope 16, and the elevating mechanism 12 is flexibly connected with controller 2 by rope 16.

When it is implemented, when controller 2 packs up the rope 16 of control pulley 15, expansion link 11 is shunk to workbench 19 Side is moved, and aerator main body tends to be horizontal, and when controller 2 unclamps the rope 16 of control pulley 15, expansion link 11 is away from work The side of platform 19, aerator main body tend to be vertical；When the position of pulley 15 is fixed, by controlling the rope of elevating mechanism 12 to change Become the height of elevating mechanism 12.

When it is implemented, as shown in Fig. 1 and prominent 2, the arbor of the motor 3 is connected by shaft coupling 9 with drive shaft 10, The outer tube 8 is socketed on outside drive shaft 10, and the tail end of the outer tube 8 is sequentially provided with agitating paddle 17 and annular blade 18.

When it is implemented, the agitating paddle 17 is swept-back agitating paddle, impeller material preferably uses high-strength engineering plastic, Mitigate the deadweight in water, it is only 0.2 to reduce waterpower imbalance and power attenuation, material friction coefficient, and frictional force is small in water, Water flow velocity is faster.
