Abstract
The utility model relates to a paddle, in particular to a slurry or white water circulating and stirring turbulent-flow type paddle in the light industrial papermaking industry. The turbulent-flow type paddle comprises a connection flange, turbulent-flow type blades are disposed on the connection flange, each turbulent-flow type blade is provided with an inlet edge, an outlet edge, a back surface and a work surface, and the inlet edge, the outlet edge, the back surface and the work surface are integrated. The turbulent-flow type paddle is strong in slurry or white water circulating and stirring actions, reduces operation energy consumption and increases operation reliability.
Description
Technical field
The utility model is a kind of paddle, the circulation of slurry or plain boiled water and stirring turbulent flow type paddle in particularly a kind of light industry paper industry.
Background technology
The spiral paddle of available technology adopting, it is little to the axial thrust of slurry or plain boiled water, radially stir then bigger, radially power is about 2.3 with the ratio of axial thrust, therefore it is less to the axial promotion of slurry or plain boiled water in pond or the groove, mixing effect still can, but circulating effect is not very desirable, promptly easily makes slurry in pond or the groove bottom or plain boiled water sedimentation or wadding poly-; Hydraulic efficiency is very low, is about 60%, and operation energy consumption is higher; Its volume is big slightly; It two is to adopt the axial-flow type paddle, it is very big to the axial thrust of slurry or plain boiled water, radially stir then less, radially power is about 0.6 with the ratio of axial thrust, therefore it is less to the radially stirring of slurry or plain boiled water in pond or the groove, circulating effect still can, mixing effect is not very desirable, promptly easily makes slurry in pond or the groove top or plain boiled water sedimentation or wadding poly-; But efficient is higher, generally is about 80%, and operation energy consumption is lower; Its volume is very big.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of two resultant effects of circulation and stirring that improve slurry or plain boiled water are provided, and promptly guarantees slurry or the not sedimentation of plain boiled water in pond or the groove or does not wad a quilt with cotton poly-; Optimize hydraulic performance, hydraulic efficiency is greater than 80%, farthest to reduce its operation energy consumption; Reduce the blade volume, improve the turbulent flow type paddle of operational reliability.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of turbulent flow type paddle comprises connecting flange, and described connecting flange is provided with the turbulent flow type blade, is provided with inlet side, outlet limit, the back side and working face in the described turbulent flow type blade, described inlet side, outlet limit, the back side and being integral of working face.
This turbulent flow type paddle structure, it mainly is made up of turbulent flow type blade, inlet side, angle modulation screw row, the back side 4, set bolt groove, working face, connecting flange and outlet limit.β is paddle laying angle or operating angle among the figure, mainly plays the axial advance effect; γ is the paddle lift angle, a main radially agitaion.L
iBe different-diameter D
iUnder the transversal chord length, B
iBe different-diameter D
iUnder the maximum cross-section width.
The waterpower design of this turbulent flow type paddle all meets the requirement of ternary flow field, and paddle laying angle or operating angle β are 10 ° of-50 ° of variations from inside to outside, and paddle lift angle γ is 0-15 °, and blade is similar to wicker leaf shape, keeps different-diameter D
iUnder transversal chord length Li multiply by maximum cross-section width B under this diameter
iMultiply by this diameter D
iUnder linear velocity V
iProduct and this little one grade of adjacent diameter under the ratio of above-mentioned product be taken as 1～1.2, as L
5* B
5* V
5/ L

4* V
4=1～1.2, its radially the ratio of power and axial thrust be taken as 0.8～1; Suitable slurry concentration is lower than 6%, and the dischargeable capacity of circulation and stirring is smaller or equal to 200m
3Connecting flange is connected with the turbulent flow type blade, the turbulent flow type blade is provided with working face, the back side, inlet side and outlet limit, connecting flange is provided with angle modulation screw row and set bolt groove, wherein angle modulation screw row is the positioning screw hole of 5 ° of one group of spaces, can require the adjusting vane operating angle according to circulation and stirring; The set bolt groove is one group of kidney slot that fixed blade is used.
As preferably, be provided with paddle laying angle β in the described connecting flange, described paddle laying angle β and turbulent flow type blade are complementary, and are provided with paddle lift angle γ in the turbulent flow type blade.
As preferably, described paddle laying angle β be 10 degree to 50 degree, described paddle lift angle γ is that 0 degree is to 15 degree.
As preferably, the edge of described connecting flange is provided with uniform set bolt groove, is provided with angle modulation screw row between described set bolt groove.
Therefore, the turbulent flow type paddle that the utility model provides, strong to the circulation and the stirring action of slurry or plain boiled water, reduced operation energy consumption, improved operational reliability.

The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, a kind of turbulent flow type paddle, comprise connecting flange 1, described connecting flange 1 is provided with turbulent flow type blade 2, be provided with inlet side 3 in the described turbulent flow type blade 2, outlet limit 4, the back side 5 and working face 6, described inlet side 3, outlet limit 4, the back side 5 and working face 6 being integral, be provided with paddle laying angle β in the described connecting flange 1, described paddle laying angle β and turbulent flow type blade 2 are complementary, be provided with paddle lift angle γ in the turbulent flow type blade 2, described initial paddle laying angle β is 50 degree, described initial paddle lift angle γ is 0 degree, the edge of described connecting flange 1 is provided with uniform set bolt groove 7, and 7 of described set bolt grooves are provided with angle modulation screw row 8.
Operation principle: paddle is under certain power and rotating speed, slurry in slurry or white water chest, slurry or back flow water pump, slurry or the plain boiled water tower or the plain boiled water inlet side from the turbulent flow type blade is entered, axial and radially dual waterpower interlock effect by the generation of turbulent flow type blade, discharge from working face and outlet limit again, finish the axial promotion of slurry or plain boiled water and radially agitaion, and so repeatedly slurry or plain boiled water are circulated and stir.
