Abstract
The invention relates to a spiral self-sucking pulp pump impeller. Blades of the impeller are formed by connecting a spiral blade on a front section and a centrifugal blade in on a rear section, wherein the inside of the spiral blade is provided with a front cavity and a through hole and the inside of the centrifugal blade is provided with a rear cavity. The front cavity is communicated with the rear cavity and the through hole. The spiral blade is arranged in front of the centrifugal blade. The spiral blade and the centrifugal blade are cast into a whole. The spiral blade on the front second is a thread-head spiral consisting of three blades. The through hole is a step hole formed by a large diameter hole and a small diameter hole. The small diameter hole is connected with the front cavity. The invention has the advantages of strong self-suction force for materials with low liquidity and good passing ability.
Description
Technical field
The present invention relates to a kind of pulp pump technical field, especially relate to a kind of spiral type self-absorbing paper pulp pump vane.
Background technique
Defectives such as existing commonly used pulp pump impeller mostly is half-opened impeller greatly, and it is low that this class impeller exists efficient, and is poor for the passing ability of the material of flowability difference, and suction capacity is not strong.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, provides a kind of and has efficiently the spiral type self-absorbing paper pulp pump vane that suction capacity is strong.
The present invention solves the technological scheme that its technical problem adopts: this spiral type self-absorbing paper pulp pump vane, and blade is formed by connecting by the screw blade of leading portion and the centrifugal blade of back segment; Preceding cavity and through hole are wherein arranged in the screw blade, in the centrifugal blade rear chamber is arranged, preceding cavity is connected with rear chamber, and preceding cavity is connected with through hole.
Described screw blade is arranged at the front of centrifugal blade, and screw blade and centrifugal blade integral are cast as integrative-structure; The screw blade of leading portion is three spirals being made up of three blades.
Described through hole is the shoulder hole that is made of a large diameter hole and small diameter bore, and small diameter bore is connected with preceding cavity.
The effect that the present invention is useful is: the suction capacity for the material of flowability difference is strong, and passing ability is good.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a left view of the present invention;
Description of reference numerals: screw blade 1, centrifugal force blade 2, preceding cavity 3, rear chamber 4, through hole 5.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
With reference to accompanying drawing: this spiral type self-absorbing paper pulp pump vane, blade is formed by connecting by the screw blade 1 of leading portion and the centrifugal blade 2 of back segment, screw blade 1 is arranged at the front of centrifugal blade 2, screw blade 1 and 2 cast inblocks of centrifugal blade are into a single integrated structure, and the screw blade 1 of leading portion is three spirals being made up of three blades.Preceding cavity 3 and through hole 5 are arranged in the screw blade 1, in the centrifugal blade 2 rear chamber 4 is arranged, preceding cavity 3 is connected with rear chamber 4, and preceding cavity 3 is connected with through hole 5, through hole 5 is the shoulder holes that are made of a large diameter hole and small diameter bore, and small diameter bore is connected with preceding cavity 3.
Working principle: the matching gap in the blade profile of screw blade 1 and pump housing cross section is very little, when screw blade 1 runs up, produce vacuum state, simultaneously, the material of flowability difference is forced to stir into turbulence state, under the effect with vacuum carried forward vigorously of spiral, suck, and be pushed to rear chamber 3 by preceding cavity 2; Centrifugal force by centrifugal blade 2 produces is thrown away medium by rear chamber 3, successively finish the process that self-priming is carried.
In addition to the implementation, all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
