CN201592067U - Anti-twisting mixer - Google Patents

Abstract

The utility model provides an anti-twisting mixer which mainly solves the problems that a mixing shaft bends and deforms, equipment is easy to generate resonance and the dispersing or mixing performance of solid-phase is poor as the existing mixer is easy to twist by fibrous solid. The anti-twisting mixer is characterized in that two side surfaces of a disc (2) are fixed with parabolic-shaped blades (3) respectively; and one end of the blade (3) is connected with the side wall of a hub (1) and extends to the circumferential edge of the disc (2) in a radial shape. The anti-twisting mixer can effectively prevent the fibrous solid from twisting the blades, thus avoiding the bending and deformation of the mixing shaft and the equipment from generating resonance, and having good dispersing or mixing solid-phase effect.

Description

Antiwind agitator

Technical field:

The utility model relates to a kind of agitator, be specifically related to a kind of be used for that gas, liquid, solid disperse mutually or the mixed process solid phase in contain the agitator of fiberous material, especially antiwind agitator.

Background technology:

At chemical industry, often relate to gas in the industries such as pharmacy, liquid, Gu three-phase stirring operation, such as the purge tank mixing plant in the xanthans production process, its material is alcohol and the easy fibrous body of stopping admittedly that twines, this whipping process need be dispersed in the fibrous solid that easily twines in the liquid phase fully, often the agitator that uses is disc turbine class agitator, as shown in Figure 1, be typical six straight leaf disc turbine stirrers, its structure is a fixed disc on wheel hub, along the evenly fixing a plurality of blades vertical of disk circumferential edge with disk, the inside part of blade and disk welding or bolting, certainly blade form wherein also has a lot of variations, blade also can have a certain degree with disc and be obliquely installed, but, each blade all contacts with the fibrous solid that easily twines, a large amount of fibrous solids twine blade, agitator weight increases, cause the suffered moment of flexure of agitator to strengthen, the skew of calculating critical speeds of agitating shaft scope, thereby cause shaft flexural deformation, equipment easily produces resonance, has reduced the solid phase dispersion of agitator or the performance of mixing.

The utility model content:

Easily caused shaft flexural deformation in order to overcome existing agitator by fibrous solid winding, equipment easily produces resonance, the bad deficiency of performance that solid phase is disperseed or mixed, the utility model provides a kind of antiwind agitator, this antiwind agitator can prevent effectively that fibrous solid is wrapped on the blade, avoid shaft flexural deformation, equipment can not produce resonance yet, solid phase disperse or mix effective.

The technical solution of the utility model is: this antiwind agitator comprises the disk that is fixed on the wheel hub, and the two sides of disk are the fixing blade of parabolic shape respectively, and an end of blade links to each other with wheelboss side wall and extends to the circumferential edges of disk radially.

One side of described disk is a taper seat, and the another side of disk is the plane.

The bus of the taper seat of described disk and the angle between the bottom surface are 5～15 °.

Described blade is 3～12.

The height of described blade is 10～20% of a disk diameter.

Angle between the vertical plane of described blade and disk side is 5～35 °.

The utlity model has following beneficial effect: owing to take such scheme, when fibrous solid is fallen on the disk, the centrifugal action lower edge blade that produces in the disk rotation skids off, the parabolic shape of blade is consistent with the movement locus of fibrous solid, reduced the relative frictional resistance of blade with fibrous solid, fibrous solid can successfully skid off from disk; Because blade upwards do not have resistance point or face at disk diameter, thereby fibrous solid can not be wrapped on the blade, avoided shaft flexural deformation, and equipment can not produce resonance yet, and solid phase is disperseed or mixing effective.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

In conjunction with Fig. 3, shown in Figure 4, this antiwind agitator comprises the disk 2 that is fixed on the wheel hub 1 by Fig. 2, and the two sides of disk 2 are fixed the blade 3 of 3～12 parabolic shapes respectively, and the quantity that present embodiment is chosen blade 3 is 6.One end of blade 3 links to each other with wheel hub 1 sidewall and extends to the circumferential edges of disk 2 radially.When fibrous solid is fallen on the disk 2, under the centrifugal action that produces in disk 2 rotations, fibrous solid skids off along blade 3, the parabolic shape of blade 3 is consistent with the movement locus of fibrous solid, reduced the relative frictional resistance of blade 3 with fibrous solid, fibrous solid can successfully skid off from disk 2; Because blade 3 does not upwards have resistance point or face in disk 2 footpath, thereby fibrous solid can not be wrapped on the blade 3, avoided shaft flexural deformation, and equipment can not produce resonance yet, and solid phase is disperseed or mixing effective.

In conjunction with Fig. 4, shown in Figure 5, a side of described disk 2 is a taper seat 4 by Fig. 3, and the another side of disk 2 is plane 5.When mounted, a side of taper seat 4 in the top, has been changed the liquid form of fluid, be beneficial to skidding off of fibrous solid, mixing effect is good.

By shown in Figure 3, angle is 5～15 ° between the bus 6 of the taper seat 4 of described disk 2 and the bottom surface 7; The height of described blade 3 is 10～20% of disk 2 diameters; By shown in Figure 2, the angle between described blade 3 and the disk 2 lateral vertical side faces is 5～35 °.Above-mentioned dimensional parameters can guarantee that fibrous solid reaches good dispersion or mixed effect, can not be stuck in disk 2 tops, stirring efficiency height again for a long time.When actual design, can choose according to the concrete condition of material.
