Abstract
The invention discloses a kind of agitator arm be uniformly mixed for polyurethane foam raw material, comprise: the impeller body being provided with some wheel blades, stirring annulus is fixedly installed in the bottom outside of wheel blade, the bottom radial direction stirring annulus is provided with some stirring projections, the width stirring annulus is 1/3 ~ 1/2 of wheel blade length, the width stirring projection is stir annular width 1/5 ~ 1/8, and the height stirring projection is 30 ~ 50mm.Advantage of the present invention is: simple and practical, easy to use and polyurethane foam raw material can be made to mix, and greatly improves product percent of pass.
Description
Technical field
The present invention relates to the mixing stirring device field of polyurethane foam raw material, be specifically related to the agitator arm be uniformly mixed for polyurethane foam raw material.
Background technology
Polyurethane foam raw material mainly comprises: isocyanates, PPG, graphite powder, additive etc., need above-mentioned each raw material to be added in tempering tank during production to mix, usually be provided with the turning cylinder driven by drive unit in tempering tank, the lower end of turning cylinder is provided with agitator arm.Traditional agitator arm is common chip agitator arm.During stirring, agitator arm rotates and drives the liquid urethane raw in tempering tank to rotate, thus 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 uneven phenomenon, thus causes later product qualification rate to reduce.
Summary of the invention
The object of the invention is: provide a kind of structure simple, polyurethane foam raw material can be made to mix, effectively improve the agitator arm be 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 be uniformly mixed for polyurethane foam raw material, comprise: the impeller body being provided with some wheel blades, stirring annulus is fixedly installed in the bottom outside of wheel blade, the bottom radial direction stirring annulus is provided with some stirring projections, the width stirring annulus is 1/3 ~ 1/2 of wheel blade length, and the width stirring projection is stir annular width 1/5 ~ 1/8, and the height stirring projection is 30 ~ 50mm.
Further, the aforesaid agitator arm be uniformly mixed for polyurethane foam raw material, wherein, the bottom radial direction stirring annulus is provided with nine and stirs projection, stirs the convex bottom being evenly arranged in stirring annulus soon.
Further, the aforesaid agitator arm be uniformly mixed for polyurethane foam raw material, wherein, impeller body is evenly provided with three wheel blades.
Advantage of the present invention is: simple and practical, easy to use and polyurethane foam raw material can be made to mix, and greatly improves product percent of pass.
Accompanying drawing explanation
Fig. 1 is the structural representation of the agitator arm be uniformly mixed for polyurethane foam raw material of the present invention.
Fig. 2 is the structural representation that the agitator arm be uniformly mixed for polyurethane foam raw material of the present invention looks up direction.
Detailed description of the invention
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, for the agitator arm that polyurethane foam raw material is uniformly mixed, comprise: the impeller body 1 being evenly provided with three wheel blades 2, the bottom outside of wheel blade 2 is welded with and stirs annulus 3, the bottom radial direction stirring annulus 3 is provided with nine and stirs projection 4, stirs convex fast 4 and is evenly arranged in the bottom of stirring annulus 3.The width stirring annulus 3 is 1/3 ~ 1/2 of wheel blade 2 length, and the width stirring projection 4 is stir annulus 3 width 1/5 ~ 1/8, and the height stirring projection is 30 ~ 50mm.
Operation principle of the present invention is as follows: when impeller body 1 rotates stirring in mixing tank, urethane raw is tangentially rapidly to surrounding and arranges by the centrifugal force produced when wheel blade 2 rotates, be hampered after liquid urethane raw arrival bucket wall rising, liquid urethane raw above impeller is constantly from upper covering wheel blade 2, and nine urethane raws stirred below convex fast 4 continuous drive wheel blades 2 below wheel blade 2 carry out mix and blend, such urethane raw stirs above and below wheel blade 2 simultaneously, thus achieve the abundant mixing of urethane raw, ensure that urethane raw can mix, thus substantially increase the qualification rate of later product.
Claims (3)
1. for agitator arm that polyurethane foam raw material is uniformly mixed, comprise: the impeller body being provided with some wheel blades, it is characterized in that: be fixedly installed stirring annulus in the bottom outside of wheel blade, the bottom radial direction stirring annulus is provided with some stirring projections, the width stirring annulus is 1/3 ~ 1/2 of wheel blade length, the width stirring projection is stir annular width 1/5 ~ 1/8, and the height stirring projection is 30 ~ 50mm.
2. the agitator arm be uniformly mixed for polyurethane foam raw material according to claim 1, is characterized in that: the bottom radial direction stirring annulus is provided with nine and stirs projection, stirs projection and is evenly arranged in the bottom of stirring annulus.
