Description
Technical field
The utility model relates to a kind of pump, particularly relates to a kind of high-effect medium concentration pulp pump.
Background technique
Medium concentration pulp pump is a kind of new special pump, is the indispensable key equipment in pulp bleaching process.Giving top priority to what is the most important of this type of pump is: pulp fiber surface is rich in large quantity of air, and pulp density too high (7-15%) forms non-Newtonian fluid, can not carry by Ordinary Centrifugal Pumps.
The core of current medium concentration pulp pump and impeller, turbulent flow generator, due to both integrative design, in use, because both rates of wear are inconsistent, the impeller needs that worn and torn can be caused to change and turbulent flow generator when still meeting usage requirement, because of integral design, entirety is changed, increase maintenance cost, do not design sub-propeller separately.This unreasonable structure, manufacture cost is high, and in addition, due to not understanding of managing middle concentration paper pulp conveyor, in actual use, conveying effect is undesirable.
Chinese patent 201220360842.4, a kind of middle and high concentration paper pulp centrifugal pump is disclosed, by being main shaft, mechanical seal, block pulp flitch, pump postoperculum, pump head and bearing support connecting body, pump housing spiral case, half-opened impeller, fender plate before impeller, fender plate bolt and nut, impeller key, the paraxial place of impeller vacuumizes aperture, ring-type high pressure water ring-type nozzle, nozzle ring, guide vane key, irregular stator, high pressure water injection mouth, high pressure water main, high-pressure service pump, suction sleeve, steam-water separator, outlet pipe, vacuum pump, vacuum suction pipe, vacuum hole on pump postoperculum formed, as improvement: before pump intake corner is provided with nozzle ring and impeller, fender plate forms ring-type hydraulic spray mouth, paraxial place vacuumizes aperture with impeller, vacuum hole on pump postoperculum, vacuum suction pipe, vacuum pump, outlet pipe, steam-water separator, suction sleeve, high-pressure service pump, high pressure water main, high pressure water injection mouth composition vacuum suction, spray water with high pressure the circulatory system.This structure relative complex, and using effect is relatively undesirable, and processing cost is larger.
