Abstract
The utility model discloses an axial flow gas exposure oxygen increasing machine, mainly comprising a motor and a pump and a floater which are connected with the motor. A long shaft is supported by taper roller bearings at two ends and is filled with hydraulic oil by a bearing plug; an expansion part is arranged and sealed by mechanical seal; the front end of the pump is provided with a vortex-proof retaining plate; an impeller is a spiral shape at the interior and in axial flow or centrifugal shape at the exterior. The utility model has the advantages of novel structure, convenient maintenance, good oxygen increasing effect, no blocking, and being mainly applied to sewage disposal, oxygen increasing in cultivation industries, etc.
Description
Affiliated technical field:
The utility model relates to a kind of device that increases the intravital oxygen content of liquid, especially a kind of aeration oxygen replenishing machinery.
Background technology:
Along with environmental pollution is on the rise, the utilization of oxygen increasing pump more and more widely at present.As Chinese utility model ZL97242803.8, name is called " compound leaf pulling flow type high efficient aeration oxygen increasing pump " and discloses a kind of aeration oxygen replenishing pump structure, it is mainly by electric motor and link to each other with electric motor, and form for the pump in same axle center, but exist oxygenation effect poor, easily stop up, invest height, noise greatly, shortcomings such as maintenance difficult.
Summary of the invention:
At above-mentioned shortcoming, the utility model provides that a kind of oxygenation effect is good, the energy-efficient axial flow aerator of clog-free obstacle.
The technical scheme that the utility model adopted is: a kind of axial flow aeration oxygen increasing machine, mainly by motor (1), link to each other with motor (1) and be the pump in same axle center (2), and the buoyancy aid (3) around placing is formed, it is characterized in that: the major axis go-and-retum of described motor (1) and pump (2) is full of hydraulic efficiency oil and adopts taper roller bearing (4) supporting, expanding spare (5) is set and seals with mechanical seal; The front end of pump is impeller (6), and this impeller profile is axial flow or centrifugal impeller, and inside is spiral vane, and the pump front end is provided with anti-swirl baffle (7), and the pump outside is provided with guide shell (8).
The beneficial effects of the utility model are: 1, energy-efficient, easy accessibility, stable performance, clog-free obstacle, non-failure operation time are long; 2, only need to change length and the diameter and the water outlet height of guide shell, just can satisfy the aeration requirement of the aeration tank of different depths and different diameter, adaptability is strong; 3, radiation effect is good, and the radiation diameter reaches 12-22m, and 4, the anti-swirl baffle of pump barrel, can prevent effectively the disorder and the eddy current that are just producing having increased efficient because of current.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is guide shell length, diameter, the different structural representation of the present utility model of water outlet height;
Embodiment:
As shown in Figure 1 and Figure 2, it is mainly by motor (1), link to each other with motor (1) and be the pump in same axle center (2), and the buoyancy aid (3) around placing is formed, major axis (9) go-and-retum of motor (1) and pump (2) is full of hydraulic efficiency oil and supports with taper roller bearing (4), and be provided with to expand and put expanding spare (5) and seal with mechanical seal, the front end of pump is impeller (6), this impeller profile is axial flow or centrifugal impeller, inside is spiral vane, the pump front end is provided with anti-eddy current plate washer (7), and the pump outside is provided with guide (8).
When motor (1) rotates, driving the axle (9) that links to each other with motor (1) by shaft joint (10) rotates, thereby the impeller (6) of a front end is rotated, impeller produces centrifugal force, make from inlet segment (11) to suck, suck from the air inlet port (13) on axle urceolus (12) top thereby drive air, fully mixed after the anti-swirl baffle (7) by the bottom again, guide shell (8) charges into gas in the water, plays the aeration oxygen replenishing effect.Motor (1) cooperated by web member (14) with being connected mainly of pump (2).
Fig. 2 and Fig. 1 difference is that guide shell length, diameter, water outlet height are different, can be applicable to the aeration tank of different depths, different diameter respectively.
Claims (1)
1, a kind of axial flow aeration oxygen increasing machine mainly by motor (1), links to each other with motor (1) and is the pump in same axle center (2), and the buoyancy aid (3) around placing is formed; It is characterized in that: the major axis go-and-retum of described motor (1) and pump (2) is full of hydraulic efficiency oil and adopts taper roller bearing (4) supporting, expanding spare (5) is set and seals with mechanical seal, the front end of pump is impeller (6), this impeller profile is axial flow or centrifugal impeller, inside is spiral vane, the pump front end is provided with anti-swirl baffle (7), and the pump outside is provided with guide shell (8).
