Abstract
The invention discloses a slurry pump rotor provided with an exhaust structure, and relates to the technical field of machinery. The slurry pump rotor provided with the exhaust structure comprises a centrifugal pump and a spiral conveyer, wherein an impeller (1) of the centrifugal pump is provided with an exhaust hole (2) in the axis; a conveying shaft (3) of the spiral conveyer is a hollow pipe; one end of the conveying shaft (3) of the spiral conveyer is coaxially fixed with the impeller (1); a pipe cavity of the conveying shaft (3) of the spiral conveyer is communicated with the exhaust hole (2) of the impeller (1); the other end of the conveying shaft (3) of the spiral conveyer is provided with a shaft sleeve (4) connected with a power input device; and an exhaust channel (4) is arranged in the shaft sleeve (4), and is communicated with the pipe cavity of the conveying shaft (3) of the spiral conveyer. The slurry pump rotor provided with the exhaust structure has the advantages of simple structure and reasonable design, and can effectively solve the problem of incapability of normal operation caused by the air lock phenomenon generated in the conveying of gas, solid and liquid by a general centrifugal pump.
Description
Technical field
The present invention relates to field of mechanical technique, be specifically related to a kind of Pulp pump rotor being provided with exhaust structure.
Background technique
Common centrifugal pump is when carrying containing gas-liquid-solid three liquid, and material cannot be inhaled into the impeller of pump, cannot normally run or not reach design discharge and lift, and makes pipeline produce pulsation, causes the damage of pipeline.And adopt helical feed material to be forced to send into the impeller of pump.After material is thrown away pump case by impeller, the entrance of pump becomes negative pressure.Under the effect of negative pressure, the gas sent in the material come is precipitated, and gas cannot be discharged pump case.At pump intake, place gathers in a large number, causes pump intake to become malleation, forms gas lock, cannot feed material again.
Summary of the invention
Technical problem to be solved by this invention is: for the problems referred to above, provides a kind of Pulp pump rotor being provided with exhaust structure.
Technical solution of the present invention is: it comprises centrifugal pump and worm conveyor, the impeller of described centrifugal pump is provided with exhaust port in axle center place, the conveying axis of described worm conveyor is hollow body, one end of the conveying axis of worm conveyor coaxially fixes with impeller and its tube chamber is communicated with the exhaust port of impeller, the other end is provided with the axle sleeve for being connected with power input device, and axle sleeve place is provided with exhaust passage and is communicated with the tube chamber of the conveying axis of worm conveyor.
Technique effect of the present invention is: it has structure advantage simple, reasonable in design, effectively can solve the problem that common centrifugal pump cannot normally work containing forming gas lock during gas-liquid-solid three liquid in conveying.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B direction view at Fig. 1 axle sleeve place.
Embodiment
As shown in Figures 1 to 3, it comprises centrifugal pump and worm conveyor, the impeller 1 of described centrifugal pump is provided with exhaust port 2 in axle center place, the conveying axis 3 of described worm conveyor is hollow body, coaxial fixing and its tube chamber of one end of the conveying axis 3 of worm conveyor and impeller 1 is communicated with the exhaust port 2 of impeller 1, the other end is provided with the axle sleeve 4 for being connected with power input device, and axle sleeve 4 place is provided with exhaust passage 4 and is communicated with the tube chamber of conveying 3 axle of worm conveyor.
The impeller 1 of described centrifugal pump is the structure that the centre overlapped by four pieces of tabular bodys has a square hole, and the two ends of this structure are fixed with the circular plate that Liang Kuai center is provided with through hole.
The conveying axis 3 of described worm conveyor is connected by uniform dunnage 5 with between described axle sleeve 4.
Spiral of the present invention is hollow, and after material is thrown out of pump case, the malleation produced in inlet is discharged pump from the cavity at the center of spiral.In the feeding pump entirely making material continue, complete the process of conveying.
