Setting sealing guide plate, sealing guide plate and flat deflector, arc panel and groove body inner wall weld, and from groove body inner wall to flat deflector
Direction tilts obliquely.Flat deflector design can be effectively reduced the flowing of slurry in the transition position of arc panel and groove body inner wall
Resistance reduces reactive loss；By sealing guide plate obliquely, convenient for slurry is led into groove body.
Preferably, groove body bottom mounting foot is supported hydraulic pulping trough.
Possessed beneficial effect is the utility model compared with prior art:
1, not only play the role of changing slurry eddy flow direction by arc panel, shorten the pulping solution time, but also play guidance slurry
Expect the effect to groove body flows；It can be to slurry by baffle upper plate in flow-guiding structure obliquely and two sides deflector
Material plays top-down guiding function, while two sides deflector can effectively change the flow direction of groove body internal upper part slurry
The waterpower size degradation effect of slurry is improved to improve hydraulic shear and pulping efficiency with turbulence intensity.
2, flat deflector reduces pulp flow resistance, reduces reactive loss.
3, the use for dividing slurry item while improving the turbulence intensity of groove body bottom slurry, and forces slurry to hang down in groove body
Histogram generates rotation speed gradient upwards, further increases pulping effect.
4, the utility model is applied in hydrabrusher, the situation that hydrabrusher is constant in configuration power can be made
Under, production capacity improves 8% or more, and reactive power consumption reduces, and energy conservation and consumption reduction effects are good.
