Abstract
The utility model discloses a plastic and rubber blade of an integrated aerator, which comprises an impeller body and an upper flange. The impeller body comprises blades and a wheel cone. The utility model is characterized in that a plurality of upright ribbed boards are arranged on the circumferential five equilibrium points between the upper flange and the impeller body; one end of each ribbed board is connected with the impeller body, and the other end is connected to the upper flange; the ribbed boards, the impeller body and the upper flange are formed by one-step injection molding. By the structure, as the impeller body and the upper flange are both formed by injection molding, the utility model not only reserves the advantages of light weight and good dynamic efficiency, but also has the advantages of corrosion resistance, long service life and low cost; meanwhile, the impeller body, the upper flange and connecting ribbed boards are formed by integral injection molding, and are manufactured in one piece, so the utility model has simple structure and processing and convenient installation and maintenance. The utility model is an ideal tool for aquiculture.
Description
Technical field
The utility model relates to a kind of aerator device that is used for aquaculture, specifically relates to the oxygen increasing machine impeller of injection molded.
Background technique
The oxygen increasing machine impeller of known technology has the water lift impeller that adopts inverted cone, 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-rupturing, working 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 applicant has applied for ZL01240711.9 number " a kind of oxygen increasing machine impeller " patent June 1 calendar year 2001, the mold for injection molding patent of also having applied for this impeller simultaneously, its patent No. is ZL01242788.8, it be adopt impeller body and on connect the dish injection molded, on connect dish for the tapered disk structure, impeller body and on connect the discone disk and link together by fastening piece.Said structure has solved the big problem of weight of corrosion and impeller, but the same relatively complexity of processing that exists is installed trouble, and complex structure is subjected to force intensity limited.
Purpose
The purpose of this utility model is to provide a kind of not only utilization efficiency height, the life-span is long, cost is low, and structure and processing are simple simultaneously, installation and maintenance are convenient, stressed good oxygen increasing machine impeller.Technological scheme
For achieving the above object, the utility model is to adopt following scheme to realize: it comprise impeller body and on connect dish, impeller body comprises blade and wheel cone, it is characterized in that, on connect the dish and impeller body between the circumference equal diversion point be provided with some upright gussets, gusset one end connects impeller body, and an end connects dish on connecting, gusset, impeller body and on connect dish by the one piece injection molded.
Be provided with the gusset that is connected with impeller body in the big end of each blade.Beneficial effect
After adopting said structure, because impeller body and on connect dish all by an injection molded, not only kept in light weight, dynamic efficiency is better, also is not afraid of corrosion, long service life, the advantage that cost is also low, simultaneously impeller body with on to connect dish be to be shaped by integral molded plastic with being connected gusset, make single forming, structure and processing simply, installation and maintenance conveniently.
Description of drawings and embodiment
Be described further below in conjunction with drawings and Examples.Fig. 1 is the structural representation of the utility model oxygen increasing machine impeller; Fig. 2 is Figure 1A-A sectional structure schematic representation; Fig. 3 is big end of blade and wheel cone joint sectional view.
As Fig. 1, shown in Figure 2, oxygen increasing machine impeller of the present utility model comprise impeller body and on connect dish (3) and constitute, impeller body comprises blade (1) and wheel cone (2), on the circumference equal diversion point that connects between dish (3) and impeller body wheel cone (2) be provided with 6 upright gussets (4), gusset (4) one ends connect impeller body wheel cone (2), one end connects dish (3) on connecting, gusset (4), impeller body and on connect dish (3) by the Integratively injection molded, gusset (4) is formed by two triangular panels (4-1) and block length side's plate (4-2) system of enclosing, as Fig. 3, be provided with the gusset (5) that is connected with impeller body in the big end of each blade, to strengthen rigidity and intensity.
Above-mentioned gusset can have multiple structure shape, and as directly being made of triangle or right-angled trapezium, gusset also can have 8,12 etc. some.They all belong to protection domain of the present utility model.
Claims (5)
