Abstract

The invention relates to a stirring blade. Straight blades are uniformly distributed along the circumference of a hub on the outer wall, two side roots of each blade are provided with reinforcing bones, an axle hole on the hub is composed of two sections of connected coaxial holes, wherein the first section of hole is a round hole, the second section of hole is a cone hole, and the first section of hole is equipped with a key groove. A counterbore is arranged between the middle part of the second section of hole and the hub outer curved surface, and the axis of the counterbore and the axis of the second section of hole form an acute angle or obtuse angle. Compared with the prior art, the stirring blade provided by the invention has the advantages of high strength, difficult deformation and damage, firm connection, stable operation, and improvement of production efficiency, etc.

Description

A kind of propeller-blade

Technical field is the present invention relates to a kind of component of machine, more particularly, to a kind of agitator parts.

Background technology agitator is the mixing plant of extensive chemical industry, petrochemical industry, mining, food, medicine and other fields, existing Agitator mainly include propeller mixer, turbine agitator, paddle agitator and anchor agitator, and practical application More is paddle agitator, and the blade of paddle agitator is the important building block of agitator, and the performance height of blade is then straight Connect working (machining) efficiency and the level of impact agitator, existing propeller-blade straight oar leaf and oblique leaf blade respectively, wherein straight leaf Blade is made up of uniform prismatic blade outside wheel hub and its, traditional straight oar leaf in actual application, especially More in the internal impurity of stirring material, in the case that mixing power is huge, the insufficient strength of blade, easily cause blade breakage and deformation； And wheel hub is when being connected with axle, substantially take bonded, but yet suffer from the phenomenon that wheel hub comes off and occur, directly affect stirring Efficiency.

It is an object of the invention to provide a kind of propeller-blade, this propeller-blade intensity is high, not variable for content of the invention Shape and breakage, stable connection, operate steadily, improve production efficiency, reduces production cost, structure, process is simple, cost of manufacture Low, long service life.

The invention mainly comprises wheel hub, blade and strengthen bone, the wherein outer wall of wheel hub along its circumference uniform distribution prismatic blade, one As be 6 straight leaves, the both sides root of each blade described sets reinforcement bone, and strengthening bone is the metal derby being connected as a single entity with wheel hub, blade, It is identical with the material of blade, and strengthening bone has 3 faces, the plane that one face is attached with blade outer wall, and another face is and wheel The curved surface that hub outer wall attaches, can be plane or curved surface with blade, the non-attaching face of wheel hub；The axis hole of above-mentioned hub interior is by phase The two sections of coaxial apertures composition connecing, the wherein first sector hole is circular hole, and one end of the first sector hole is located on wheel hub end face, the other end with One end of second sector hole is connected, and the second sector hole is bellmouth, and the diameter at its end that connects with the first sector hole is identical with the first sector hole, the The other end of two sector holes is located on the end face of wheel hub, and above-mentioned first sector hole sets keyway；The middle part of above-mentioned second sector hole and wheel hub Counter sink is set, the axis of the axis of counter sink and the second sector hole is at an acute angle or obtuse angle between positive camber.

Set reinforcement bone between the blade of the present invention and wheel hub, strengthen bone and when agitator runs into complex working condition, blade is played The protection of certain protective effect, especially root, reduces deformation and the generation of damaged probability；When wheel hub is connected with rotating shaft, remove Take bonded outer, add the form of bellmouth and dormant bolt, wheel hub can be made more firm with the connection of rotating shaft, minimizing comes off Phenomenon occurs.

The present invention compared with prior art has intensity height, is unlikely to deform and damaged, stable connection, operates steadily, improves Production efficiency, reduces the advantages of production cost, structure, process is simple, low manufacture cost, long service life.

Brief description Fig. 1 is the schematic front view of the present invention.

Fig. 2 is the A-A view of Fig. 1.

In the schematic diagram of propeller-blade shown in Fig. 1 and Fig. 2 for the specific embodiment, the outer wall of wheel hub 1 is along its circumference Uniform 6 prismatic blades 2, the both sides root of each blade described sets reinforcement bone 3, strengthens bone and is connected as a single entity with wheel hub, blade Metal derby, it is identical with the material of blade, strengthens the plane that bone has 3 faces, one face 4 and blade outer wall to attach, another Face 5 is the curved surface attaching with hub outer wall, is plane 6 with blade, the non-attaching face of wheel hub；The axis hole of above-mentioned hub interior is by phase The two sections of coaxial aperture compositions connecing, the wherein first sector hole 7 is circular hole, and one end of the first sector hole is located on wheel hub end face, the other end It is connected with one end of the second sector hole 8, the second sector hole is bellmouth, the diameter at its end that connects with the first sector hole and the first sector hole phase With the other end of the second sector hole is located on the end face of wheel hub, and above-mentioned first sector hole sets keyway 9；The middle part of above-mentioned second sector hole Set counter sink 10 and wheel hub positive camber between, the axis of counter sink is at an acute angle with the axis of the second sector hole.
