Abstract

The mixing rod having attached blades, the blades being of the propeller type or the impeller type, including propellers or impellers that are elongated flat-plate, curved, or contoured. The blades have arched projections extending upward or downward, or both. The arched projections are formed so that material to be blended or mixed can flow through the arch, that is, under the arch, when the blades are rotated. The blades optionally have apertures or holes therethrough, which apertures or holes, when present, are under or otherwise adjacent to the arched projections.

Description of drawings

Fig. 1 be according to an embodiment of the invention mixing apparatus have a little relief side view;

Fig. 2 is according to the side view of the mixing apparatus of alternate embodiments of the present invention, two groups of blades of demonstration.

The specific embodiment

In order to promote understanding to the principle of the invention, now will be with reference to the embodiment shown in a few width of cloth views of accompanying drawing, and will use specific language to describe the present invention.For succinctly, similar element will all indicate with identical Reference numeral in the accompanying drawings with parts.Yet should understand; Be not to be intended to limit scope of the present invention whereby, it is normal the generation that other application of the such change in the device that illustrates and the further modification and the principle of the invention shown in accompanying drawing should be regarded as the technical staff in the correlative technology field of the present invention.

With reference to Fig. 1, illustrate according to mixing apparatus of the present invention or install an embodiment of 10.Said device comprises axle 12, is also referred to as bar 12 sometimes.Axle 12 is by the traditional brill (not shown) or the similar motorized power source at 14 places are rotatably driven in the top.The lower end 16 of axle 12 has screw thread 18, is used to receive the screw or the propeller blade that wherein have the hole.Mixing auger oar 20 is attached to the lower end 16 of axle 12.As exemplary display, screw 20 is a slice plates, and it has circular central opening and crooked outer end.Through screw 20 being screwed on the screw thread 18 on axle 12 lower ends 16, screw 20 is attached to the lower end 16 of axle 12.Screw 20 can remain in the correct position on the axle 12 through conventional apparatus, and conventional apparatus can comprise nut 28 and lock washer 30.When being fixed to axle 12 the time, screw 20 forms the reverse blade-

section

24 and 26 that extends, and its edge stretches out perpendicular to the axis of axle 12.Preferably, two screws 20 are to be fixed to axle 12 along axle 12 isolated arrangements.

Each outward extending blade-

section

24 or 26 necessarily angle of attack is angled in the flow, preferably is angled in the flow with low incidence.Alternately or in addition, each blade-section that radially extends 24 or 26 can be bent or by moulding, or not only has been bent but also by moulding, in mixed process, to reduce turbulent flow.When adopting two isolated screws, can select bending direction and given configuration, downward to force mixture (i), (ii) make progress, (iii) between screw, or (iv) from the screw top upwards and from the screw bottom downwards.

Perhaps, screw 20 can comprise two or more blades, and 16 to sentence balanced arrangement outstanding from axle 12 in the lower end for it.In this alternative arrangement, blade can be integrally formed, and on hub portion, to extend radially outwardly or to stretch out, said hub portion has the boring with the lower end 16 of fixed engagement mode receiving axes 12.In another alternative, blade can have the hole in its end or near its end, and can be thus through being fixed to the lower end 16 of axle 12 on the screw thread on the lower end 16 that each blade is screwed into axle 12 or through other fixing means.Blade can remain in the correct position on the axle 12 through conventional apparatus, and said conventional apparatus can comprise nut 28 and lock washer 30.

A plurality of arch protuberances 40 are arranged in upper surface, lower surface or upper surface and the lower surface of each blade-section 24 and 26.Arch protuberance 40 arranges that at least one surface that is used for from blade-

section

24 and 26 is outwards outstanding.The profile of arch protuberance 40 can be semicircle, along the elongate of projected direction or from axle 12 radially outward direction be elongate.Can be randomly, blade has the hole of running through its formation.

Cutting or otherwise form and pass the joint-cutting of blade, and the blade material between joint-cutting of stretching up or down can form arch protuberance 40 and residual hole 42 to form arch.The length of joint-cutting can be according to thickness and the ductility or the draftability variation of blade material.The profile of arch can be semicircle, along the projected direction elongate or from axle 12 radially outward direction be elongate.In another alternative, can form protruding peak and downwards from the S shape arch at another protruding peak of the apparent surface of blade-section outstanding (for example outstanding) with from a surface of blade-section outstanding (for example projecting upwards).

Another alternative form that forms arch protuberance 40 does; The hole of blade-

section

24 or 26 or 24 and 26 is passed in cutting or formation; The supporting crooked joint-cutting that cutting or formation and hole are adjacent; The material of the blade-section between crooked up or down then two joint-cuttings is to form arcuate material above said hole.Said bending can make the surface of arch perpendicular to blade-section, or alternately, said bending can make arch tilt along the blade movement direction or away from said blade movement direction.When arch tilted about blade surface, blade can be randomly not angled along the direction of motion, not by moulding or neither angled yet not by moulding along the direction of motion.

The purpose of a plurality of arch protuberances 40 is the little agglomerates that make in the outstanding arch crushed mixture.For example plaster a wall mud when being used to use, slowly water is added to being loaded with in the dry powdered container of material of plastering a wall usually, and mixture is mixed when preparation.When outer wet stock surrounds little drying material aggregation, form the material agglomerate.Though the blade edge along the circus movement direction is used to pulverize agglomerate, be to use arch protuberance 40 to increase the effective length that agglomerate is pulverized the edge, cause immixture to improve and more effective mixing.Comparable blade-section 24 in the edge of

arch protuberance

40 and 26 relative root face are thinner and more sharp-pointed, obtaining more effective agglomerate through said device simultaneously and pulverize at the said blade of blade-section edge safe handling.

In addition, except replace to cut or the cut-off blade material, the arch protuberance can form through material is fixed on blade-section 24 and 26.The arch protuberance of these increases can randomly use with the aforesaid hole of passing said blade.

Though shown in a few width of cloth views of accompanying drawing and in aforementioned description, describe exemplary embodiment of the present invention in detail; But should understand; Only show and described exemplary embodiment, can change and revise and do not depart from the scope of pointing out in the concrete claim below of the present invention.
