Description

Unitary Impeller

Technical field

The utility model relates to a kind of impeller that is used on the sewage disposal device aerator, relates in particular to the impeller of a kind of fan blade and water impeller integral structure.

Background technology

At present, the impeller in the underwater jet aeration machine generally is made up of fan blade and water impeller, adopts propeller structure formation, the balance of this impeller is difficult to control, there are problems such as the complete machine serviceability is poor, work-ing life is short, simultaneously owing to adopt split-type structural, installation, troublesome maintenance.As the Chinese patent publication number is CN 2727456 Y, open day is on September 21st, 2005, name is called the utility model of " aerator fan blade ", this application case discloses and has comprised hollow shaft sleeve, air blade, the upper cover plate of fixedlying connected with air blade, low bottom-disc, be arranged at perforation circle on the upper cover plate, be arranged at the fan blade of fin in the hollow shaft sleeve etc., this utility model must make up with water impeller, drive fan blade and water impeller run up when motor rotation, make gas-vapor mix, just can reach the dissolved oxygen purpose.The major defect that this utility model exists is that the overall axial dimension of fan blade and water impeller is excessive, when on aerator, using because long with being connected of motor output shaft, and balance is poor, have influence on the reliable and work-ing life of complete machine, while structure more complicated, difficulty of processing is big, also makes troubles to installation and maintenance.

Summary of the invention

The utility model is problem such as fan blade, water impeller complex structure, balance in the underwater jet aeration machine is poor, installation and maintenance trouble in order to solve, and a kind of modern design, simple in structure, reliable, Unitary Impeller that result of use is good, convenient for installation and maintenance are provided.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises wheel hub, described wheel hub periphery is provided with horizontal plane and the vertical web plate of wheel hub central axis, the some back blades that produce negative pressure when high speed rotating above described web plate upper and lower end face is respectively arranged with and can makes with can make below fluid produce some primary blades of rotation.

As preferably, be respectively arranged with horizontal plane and described web plate end face parallel annular back shroud and annular front shroud on back blades, the primary blades, form blast inlet and water-in between described back shroud, front shroud hollow space and the wheel hub excircle, described primary blades will be separated into several gas-liquid mixed chambers between back shroud and the front shroud.

As preferably, the quantity that is arranged at the back blades on the web plate is 3 to 6, and described back blades is distributed on the web plate end face radially.

As preferably, the quantity that is arranged at the primary blades on the web plate is 5 to 12, and described primary blades is distributed on the front shroud radially with certain spiral camber.

The utility model compared with prior art has following obvious advantage and positively effect:

1. novel in design, simple in structure.Because the utility model adopts fan blade and the design of water impeller integral type, sets up blast inlet and water-in up and down separately in the middle of the impeller, utilizes primary blades to be separated into several gas-liquid mixed chambers between the front and rear cover plate simultaneously, so novel in design, simple in structure.

2. reliable, result of use is good.Because the radial dimension that connects with motor output shaft of the utility model is little, balance is good, makes that complete machine is reliable, kinetic equation loss is little.

3. installation, easy to maintenance.Since the utility model fan blade and the design of water impeller integral type, compact construction, and the one-piece construction of aerator has been simplified in the setting of gas-liquid mixed chamber simultaneously again, so install, safeguard very convenient.

Description of drawings

Fig. 1 is the structural representation of a kind of embodiment of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is that a kind of embodiment of the present utility model is applied to the structural representation on the aerator.

Embodiment

Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:

Extremely shown in Figure 2 as Fig. 1, a kind of preferred embodiment comprises wheel hub 12, described wheel hub 12 peripheries are provided with horizontal plane and the vertical web plate 13 of wheel hub 12 central axis, 3 back blades 14 that produce negative pressure when high speed rotating above described web plate 13 upper and lower end faces are respectively arranged with and can make with can make below fluid produce 6 primary blades 15 of rotation, described back blades 14 is provided with horizontal plane and web plate 13 end face parallel annular back shrouds 16, form blast inlet 17 between described back shroud 16 hollow spaces and wheel hub 12 excircles, described back blades 14 is distributed on web plate 13 end faces radially, described primary blades 15 is provided with horizontal plane and web plate 13 end face parallel annular front shrouds 18, form water-in 19 between described front shroud 18 hollow spaces and wheel hub 12 excircles, described primary blades 15 is distributed on the front shroud 18 radially with certain spiral camber, and described primary blades 15 will be separated into 6 gas-liquid mixed chambers 20 between back shroud 16 and the front shroud 18.

As shown in Figure 3, when impeller 6 is used on aerator, impeller 6 connects with motor 1 output axle head, and be arranged in the circular channel 5, the outlet position, gas-liquid mixed chamber of impeller 6 is corresponding to circulation channel 9 entrance location of circular channel 5, when impeller 6 under motor 1 drives during high speed rotating, under the effect of back blades, its top, central zone produces negative pressure, because back blades blast inlet and circular channel 5 interior air chambers 8 communicate, also produce negative pressure in the air chamber 8, owing to air chamber 8 communicates with lower inlet duct 7 with last inlet pipe 4, so it is indoor that outside air is drawn into back blades gas-liquid mixed all around; Simultaneously under the effect of primary blades, drive the liquid in rotation of 5 belows, circular channel, it is indoor that liquid is drawn into gas-liquid mixed by water-in, under the acting in conjunction of back blades and primary blades, liquid-to-air acutely mixes in the gas-liquid mixed indoor high-speed, stir, pulverize, and formation emulsus mixed solution, enter into the indoor active sludge of gas-liquid mixed from the primary blades below simultaneously and also be sheared into less bulk tissue, because the spiral camber of primary blades design, under action of centrifugal force, enter in the circulation channel 9 through mixed liquid in gas-liquid mixed chamber and active sludge group, thereby finish air-breathing, water inlet and gas-vapor mix, whipping process.

The utility model is applicable to the organic sewage processing and water body is carried out the aerator of reoxygenation and purification of water quality.
