Abstract
The utility model discloses an automatic aerator impeller which comprises an impeller body 1 and an upper flange 2. The utility model is characterized in that the impeller body 1 is connected with the upper flange 2 by a fastener; the impeller body and the upper flange are both formed by injection molding; the impeller body is integrally formed by injection molding of blades and a wheel cone; the impeller body 1 and the upper flange 2 can be connected by a plurality of modes, such as screw connection, bolt connection, etc.; convex and concave tooth slots can also be arranged at the positions where the impeller body and the upper flange are connected with a junction surface, and the convex and the concave tooth slots are mutually engaged. By the structure, the impeller has the advantages of high service efficiency, long life time, low cost and convenient dismounting and maintenance. The utility model is an ideal tool of aquiculture.
Description
The utility model relates to a kind of aerator device that is used for aquaculture, specifically relates to the impeller of aerator.
The oxygen increasing machine impeller of known technology has the water lift impeller that adopts back taper, generally comprise blade, on connect the dish and the wheel cone, above-mentioned parts generally all have the steel material of employing to be welded through machining and shaping, because impeller is in the water for a long time, what have also is in the seawater, Exposure to Sunlight aqueous corrosion, working environment are very abominable, and therefore very easily corrosion damages and scraps, the weld easy fracture, service life is short, maintenance difficult, processed complex is simultaneously because the weight of impeller is big, it is low to exist dynamic efficiency, drawbacks such as waste electric energy, also have and adopt stainless steel to make, also only overcome the problem of easy-to-rust, and cost is also higher.
The purpose of this utility model is to provide a kind of service efficiency height, the life-span is long, cost is low, dismounting is easy to maintenance oxygen increasing machine impeller.
For achieving the above object, the utility model is to adopt following scheme to realize: it comprise impeller body and on connect dish and constitute, impeller body and on connect dish all by injection molded, impeller body is shaped by blade and wheel cone integral molded plastic, impeller body and on connect dish and link together by securing member.
The Along ent place is provided with the bolt frame on the circumference in the described impeller body, connects that the Along ent place is provided with screw on the dish circumference on described, by this bolt frame and screw with bolt with impeller body and on connect dish and be fixed together.
The Along ent place has the hole on the circumference in the described impeller body, connects that the Along ent place is provided with bearing pin on the dish circumference on described, squeeze by bearing pin in the hole of inserting impeller body with impeller body and on connect dish and be fixed together.
Connect on described that the Along ent place has the hole on the dish circumference, the Along ent place is provided with bearing pin on the circumference in the described impeller body, by bearing pin squeeze insert in the hole that connects dish with impeller body and on connect dish and be fixed together.
After adopting said structure, because impeller body and on connect dish all by injection molded, in light weight, dynamic efficiency is better, be not afraid of corrosion yet, long service life, handling ease, cost is also low, simultaneously impeller body and on to connect dish be to link together by securing member, the two is more easily installed, and might as well dismantle simultaneously, and is easy to maintenance.
Be described further below in conjunction with drawings and Examples.
Fig. 1 is the sectional structure schematic diagram of the utility model oxygen increasing machine impeller;
As shown in Figure 1, oxygen increasing machine impeller of the present utility model comprise impeller body 1 and on connect dish 2 and constitute, impeller body 1 and on connect dish and 2 all be shaped by mold injection, impeller body 1 is shaped by blade 1-1 and wheel cone 1-2 integral molded plastic, impeller body 1 with on connect dish 2 and link together by bolt, the Along ent place is provided with the bolt frame on the circumference in the described impeller body, fluted on this fixed mount 3, the centre of groove is porose, connect that the Along ent place is provided with screw 4 on dish 2 circumference on described, by this bolt frame 3 and screw with bolt with impeller body 1 and on connect dish 2 and be fixed together.
Above-mentioned impeller body 1 with on connect dish 2 connected modes and can also adopt other modes, as adopt the connection of latch, the Along ent place has the hole on the circumference in impeller body 1, connect on described that the Along ent place is provided with bearing pin on dish 2 circumference, squeeze to insert by bearing pin in the hole of impeller body with impeller body and on connect dish and be fixed together; Perhaps adopt to connect that the Along ent place has the hole on dish 2 circumference on described, the Along ent place is provided with bearing pin on the circumference in described impeller 1 body, insert by bearing pin in the hole that connects dish with impeller body and on connect dish and be fixed together; For make impeller body 1 with on connect dish 2 and be connected more firmly, can also locate to be equipped with the convex-concave teeth groove on the connection composition surface of the two, the two is connected together mutually.They constitute the different embodiment of the utility model, all belong to protection domain of the present utility model.
