Abstract

The invention relates to a dentate disc axial flow reinforced stirrer, and belongs to the technical field of stirring. According to the dentate disc axial flow reinforced stirrer, a wheel hub and a disc are designed, teeth are designed on the periphery of the disc, and axial flow blades produced through bending after cutting are designed on the disc between the teeth and the wheel hub. With the present invention, comprehensive process parameters such as shearing force, flow field, circulating flow and the like can be concurrently achieved, problems of weak axial circulation capability and easy material accumulation on the bottom of the flow field of the traditional dentate disc stirrer are effectively solved, and the structure has advantages of material saving material and convenient manufacturing.

Description

The reinforced agitator of fluted disc axial flow

Technical field

The invention belongs to the stirring technique field, the agitator specifically used on mixing plant.

Background technology

Mixing plant is widely used in the industries such as bio-pharmaceuticals, petrochemical industry, fine chemistry industry, water treatment, food and drink, metallurgical mining industry and environmental protection, difference according to material difference and technological requirement, the flow regime such as the shearing force that requires agitator to produce, flow field pattern, circulation rate and technical process all change, and people are in order to realize that different purposes are all for developing more suitably type of stirrer effort at present.

Summary of the invention

The object of the invention is to design a kind of agitator, not only have good shearing force, and realize required field of flow, improve circulation ability, this structure of while has easy to process, the advantage of saving material.

The present invention solves the problems of the technologies described above adopted technical scheme: invent the reinforced agitator of a kind of fluted disc axial flow, be designed with wheel hub, disk, disc circumference is designed with tooth, the quantity of tooth is even number, be designed with the axial blade of bending after cutting open on the disk between tooth and wheel hub, the quantity of axial blade is 2～4, and press circumference uniform distribution, the angle α on axial blade and plane, disk place is between 10～60 °, screw on stirrer hub is for being fixed on shaft by agitator, during work, on disc circumference, lower tooth has extremely strong shear agitation effect to material, the axial blade of bending on disk, can strengthen the axial circular flow in flow field, it is the inswept fluid of axial blade of bending, make fluid cut open by disk the tapping suction that bending produces, along the direction parallel with axle, discharge, compare traditional fluted disc agitator by only radially discharge currents, run into the circular flow up and down that tank skin produces up and down separately and indirectly, cyclic process with stronger fluid, avoid the bottom buildup, form desirable field of flow, simultaneously in this structure manufacture process, in the situation that the material of proof strength by disk itself cut open after bending produce axial blade, save material, easily manufactured.

The invention has the beneficial effects as follows: realized the composite technology parameters such as shearing force, field of flow, circular flow simultaneously, and there is the material, easily manufactured of saving, can be applicable to the stirring material of corresponding technological requirement.

The accompanying drawing explanation

Fig. 1 is the reinforced agitator isometric drawing of fluted disc axial flow.

Fig. 2 is the overall plan view before agitator disk does not cut open bending, and line 7 is curved tooth bending lines, and line 8 is that disk cuts open line, and line 9 is axial blade bending lines.

Fig. 3 is axial blade bending part partial sectional view.

In figure, 1. screw, 2. wheel hub, 3. disk, 4. tooth, 5. disk cuts open the perforate that bending produces, 6. axial blade, 7. curved tooth bending line, 8. cut open line, 9. the axial blade bending line.

The specific embodiment

In the reinforced agitator embodiment of the axial flow of fluted disc shown in figure, the installation of agitator is sleeved on shaft and coordinates screw 1 to be positioned on shaft by holding screw by wheel hub 2, tooth 4 on disk is designed to 30, alternately curve up and down with disk 3 and meet at right angles at curved tooth position of broken line 7, axial blade on disk is designed to 4 by circumference uniform distribution, on disk along after cutting open line 8 and cutting open along 9 bendings of axial blade bending line, axial blade 6 is 45 ° with the angle α on disk 3 planes, place, during agitator work, fluid cuts open by disk perforate 5 suctions that bending produces, along the direction parallel with axle, discharge, thereby the axial circular flow in strengthening flow field.

Claims

1. the reinforced agitator of fluted disc axial flow, be designed with wheel hub, disk, and it is characterized in that: disc circumference is designed with tooth, is designed with the axial blade that after cutting open, bending produces on the disk between tooth and wheel hub.
