Abstract

The invention relates to an impeller device of an auger residue pump. The impeller device of the auger residue pump consists of shafts and blades, wherein a spiral blade winding by taking the shaft as a circle centre is arranged on the shaft at a water inlet end; and blades radially and uniformly distributed by taking the shaft as the circle centre are arranged on the shaft at a water outlet end, or a round disc with the shaft as the circle centre is arranged on the shaft at a water outlet end and the blades are radially and uniformly distributed on the disc. Due to the adoption of the technical scheme, compared with those of the device singly adopting the spiral blade, the delivery lift and the power of the impeller device of the auger residue pump are improved by over 30 percent and over 20 percent respectively at the same rotation speed; and the capabilities of pumping dopes and preventing blockage are not decreased at the same time.

Description

A kind of auger is taken out the impeller unit of pulp pump

Technical field

The present invention relates to a kind of auger and take out the impeller unit of pulp pump.

Background technique

The existing pulp pump impeller of taking out mainly contains following a few class: 1, receded disk impeller, and it is by being that the radially-arranged blade in the center of circle is formed with the axle, rotating speed height, lift height have certain breaking capacity, but easily block when taking out the thickness object; 2, axial-flow pump impeller, its blade are half regulating type, need adjust according to operating mode, because big, the lift of weight low can not adaptation extracted biomass pool etc. and need the operating mode that moves; 3, auger take out that the pulp pump impeller comprises that Chinese patent announces 200610134837.0 and 200610134697.7 and the patent No. of my invention be that 200820207414.1,200920008013.8,2009201644.3 and 200820175371.3 its impellers are the helical blades around the axle rotation, these equipment have extraction dope ability and are difficult for the advantage of obstruction by force, but also exist the lower shortcoming of lift; 4, self-priming sludge pump impeller is to be the radially-arranged open type blade structure in center with the axle, have lift height, advantage that flow is big, but suction is poor, especially can't draw the thickness object.

Summary of the invention

The auger that the objective of the invention is to propose a kind ofly can to draw dope, be difficult for blocking, lift is high is taken out the pulp pump impeller unit.

A kind of auger is taken out the impeller unit of pulp pump, form by axle, disk, blade, helical blade, on the axle of inlet end being is the helical blade of center of circle coiling with the axle, on the axle of water outlet end is to be the radially blade of equiblibrium mass distribution of the center of circle with the axle, also can be to have one to be the disk in the center of circle, radially be balanced distributed with blade on the dish with the axle.Blade can be that flat board also can be crooked; Blade can be that what to link to each other with axle also can be disjunct; Blade can be more than 2 or 2; Helical blade can be 1 also can be several with hour indicator on axle.Owing to adopt technique scheme to compare with the device of independent employing helical blade, lift promotes more than 30% under same rotational speed, and power also promotes more than 20%, extracts the dope ability simultaneously and the anti-blocking ability does not descend.
