Abstract
The invention discloses a stirring impeller used for stirring and mixing polyurethane foaming raw materials. The stirring impeller comprises an impeller body provided with a plurality of impeller blades, wherein a circular stirring ring is fixedly arranged on the outer side of the bottom of each impeller blade, a plurality of stirring projections are arranged in the radial direction of the bottom of the circular stirring ring, the width of the circular stirring ring is equal to 1/3 to 1/2 the length of each impeller blade, the width of each stirring projection is equal to 1/5 to 1/8 the width of the circular stirring ring, and the height of each stirring projection is 30-50mm. The stirring impeller disclosed by the invention has the advantages of being simple and practical in structure, convenient to use and capable of uniformly mixing the polyurethane foaming raw materials and greatly increasing the percent of pass of products.
Description
Technical field
The mixing stirring device field that the present invention relates to polyurethane foam raw material, is specifically related to the agitator arm being uniformly mixed for polyurethane foam raw material.
Background technology
Polyurethane foam raw material mainly comprises: isocyanates, PPG, graphite powder, additive etc., during production, above-mentioned each raw material need to be added in tempering tank and mix, in tempering tank, be conventionally provided with the turning cylinder being driven by drive unit, the lower end of turning cylinder is provided with agitator arm.Traditional agitator arm is common chip agitator arm.During stirring, agitator arm rotates the liquid urethane raw driving in tempering tank and rotates, thereby reaches the object that each raw material mixes mutually.But when agitator arm stirs, the urethane raw of partly precipitated below agitator arm easily occurs mixing inhomogeneous phenomenon, thereby cause later stage product percent of pass to reduce.
Summary of the invention
The object of the invention is: provide a kind of simple in structure, can make polyurethane foam raw material mix, effectively improve the agitator arm being uniformly mixed for polyurethane foam raw material of product percent of pass.
For achieving the above object, the technical solution used in the present invention is: the agitator arm being uniformly mixed for polyurethane foam raw material, comprise: the impeller body that is provided with some wheel blades, bottom outside at wheel blade is fixedly installed stirring annulus, the bottom of stirring annulus is radially provided with some stirring projections, the width that stirs annulus is 1/3～1/2 of wheel blade length, stirs the width of projection for stirring 1/5～1/8 of annulus width, and the height that stirs projection is 30～50mm.
Further, the aforesaid agitator arm being uniformly mixed for polyurethane foam raw material, wherein, the bottom of stirring annulus is radially provided with nine and stirs projection, stirs the protruding bottom of stirring annulus that is evenly arranged in soon.
Further, the aforesaid agitator arm being uniformly mixed for polyurethane foam raw material, wherein, is evenly provided with three wheel blades on impeller body.
Advantage of the present invention is: simple and practical, easy to use and can make polyurethane foam raw material mix, greatly improve product percent of pass.
Accompanying drawing explanation
Fig. 1 is the structural representation of the agitator arm being uniformly mixed for polyurethane foam raw material of the present invention.
Fig. 2 is the structural representation that the agitator arm being uniformly mixed for polyurethane foam raw material of the present invention is looked up direction.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the present invention is described in further detail.
As shown in Figure 1 and Figure 2, the agitator arm being uniformly mixed for polyurethane foam raw material, comprise: the impeller body 1 that is evenly provided with three wheel blades 2, the bottom outside of wheel blade 2 is welded with and stirs annulus 3, the bottom of stirring annulus 3 is radially provided with nine and stirs projection 4, stirs protruding fast 4 and is evenly arranged in the bottom of stirring annulus 3.The width that stirs annulus 3 is 1/3～1/2 of wheel blade 2 length, stirs the width of projection 4 for stirring 1/5～1/8 of annulus 3 width, and the height that stirs projection is 30～50mm.
Operation principle of the present invention is as follows: when impeller body 1 rotates stirring in mixing tank, the centrifugal force producing during wheel blade 2 rotation tangentially arranges urethane raw rapidly to surrounding, rising is hampered after liquid urethane raw arrival bucket wall, the liquid urethane raw of impeller top is constantly from upper covering wheel blade 2, and below wheel blade 2 nine stir protruding fast 4 and constantly drive the urethane raw below wheel blades 2 to carry out mix and blend, urethane raw stirs in the above and below of wheel blade 2 simultaneously like this, thereby realized the abundant mixing of urethane raw, guaranteed that urethane raw can mix, thereby greatly improved the qualification rate of later stage product.
Claims (3)
1. the agitator arm being uniformly mixed for polyurethane foam raw material, comprise: the impeller body that is provided with some wheel blades, it is characterized in that: the bottom outside at wheel blade is fixedly installed stirring annulus, the bottom of stirring annulus is radially provided with some stirring projections, the width that stirs annulus is 1/3～1/2 of wheel blade length, stir the width of projection for stirring 1/5～1/8 of annulus width, the height that stirs projection is 30～50mm.
2. the agitator arm being uniformly mixed for polyurethane foam raw material according to claim 1, is characterized in that: the bottom of stirring annulus is radially provided with nine and stirs projection, stirs the protruding bottom of stirring annulus that is evenly arranged in soon.
