Abstract
The utility model relates to a cement pulping device which applies to a containment of a nuclear power plant and belongs to the technical field of building construction. The cement pulping device comprises a main tank body with a conic bottom. One side of the main tank body is provided with a main stirring motor, an output shaft of the main stirring motor is vertically arranged downward. The output shaft is connected with a vane wheel in a transmitting mode, the bottom of the main tank body is communicated with an inlet of a centrifugal pump, and an outlet of the centrifugal pump is respectively communicated with an upper portion of the main tank body and a grout outlet through a switching valve. By utilizing the cement pulping device, materials are fully and uniformly stirred and can be rapidly made into grout, and therefore the cement pulping device can truly meets the requirement for grouting construction of a reserved pore passage of a large-scale structure, and the like.
Description
Technical field
The utility model relates to a kind of pulping device, and especially a kind of cement pulping device that is applicable to nuclear power plant containment shell belongs to technical field of building construction.
Background technology
In the prestress engineering construction of large-scale structures (like nuclear power plant containment shell, LNG tank etc.), need be in the milk to the duct of reserving, promptly in the cement mortar pressure injector tunnel of prior making, to guarantee the closely knit of structure.Therefore need a kind of device of making cement mortar, can carry out slurry production, satisfy the requirement of its ratio of mud, fluidity and temperature according to the requirement of standard, standard.Require simultaneously this device for mechanical principle reliable, use simple and fault rate low, possess operability.
Understand according to the applicant, present existing cement stirring device etc. are difficult to make the cement mortar that satisfies above requirement.
The utility model content
The technical problem that the utility model will solve is: proposes a kind ofly can satisfy construction requirements such as large-scale structures reserving hole channel grouting, and the high cement pulping device of production efficiency.
In order to reach above purpose; The cement pulping device of the utility model comprises having the awl main tank body at the end; One side of said main tank body is mounted with output shaft main stirring motor vertically downward; Said output shaft is in transmission connection with the impeller that is arranged in centrifugal pump, and the bottom of said main tank body is communicated with the import of centrifugal pump, and said centrifugal delivery side of pump is communicated with the top and the grout outlet of main tank body respectively through transfer valve.
During work, main stirring motor drives the centrifugal pump impeller rotation and produces the high speed flow, in main tank body, forms high-speed eddy, mixes stirring action efficiently thereby produce.
Main in addition tank body top is mounted with secondary stirring motor, and said secondary stirring motor extends the stirring rod that stretches in the main tank body down, and the stirring blade with cutting edge, especially double-deck stirring blade are installed in the lower end of said stirring rod.After starting secondary stirring motor, drive stirring blade 8, the main eddy current that produces that stirs is strengthened through stirring rod; Simultaneously, when main tank body adds cement, secondary agitator can make cement and water mix fast, shortens mixing time greatly.
Mix after slurrying finishes, the control transfer valve can make the cement mortar in the main tank body export from grout outlet under the effect of stirring pump.
After adopting the utility model, material can be processed slurries fast through full and uniform stirring, thereby satisfies construction requirement such as large-scale structures reserving hole channel grouting conscientiously.

The specific embodiment
Embodiment one
The cement pulping device basic structure of present embodiment such as Fig. 1 are to shown in Figure 4; Main tank body 1 one sides with awl end are mounted with output shaft main stirring motor 5 vertically downward; The lower end of its output shaft is through drive disk assembly 2---particularly; Power transmission shaft 12 through shaft coupling 13 shown in Figure 3 connects is in transmission connection with the impeller that is arranged in centrifugal pump 10, and power transmission shaft 11 is supported on the bearing block 12.The bottom of main tank body 1 is communicated with the import of centrifugal pump, and centrifugal delivery side of pump is communicated with the top and the grout outlet 9 of main tank body respectively through transfer valve 4 by total slurry pipe 3.Main tank body 1 top is mounted with secondary stirring motor 6, and this pair stirring motor extends the stirring rod 7 that stretches in the main tank body down, and the double-deck stirring blade 8 with cutting edge is installed in the lower end of this stirring rod.Its operation principle and characteristics are following:
1, directly drives 10 rotations of high speed centrifugation impeller of pump by main stirring motor 5 through turning cylinder 11 and produce the high speed flow, in tank body, form high-speed eddy;
2, secondary stirring motor 6 drives the rotation at a high speed of double-deck stirring blade 8 through stirring rod simultaneously, and the eddy current that master mixer is produced is able to strengthen; Simultaneously, when tank body adds cement, secondary agitator can mix cement and water apace, can shorten mixing time;
3, the rotation through major and minor stirring motor can make material by full and uniform stirring, processes slurries fast;
4, drive disk assembly adopts mechanical seal, and sealing is reliable, and owing to adopted two secondary angular contact ball bearings 12, has eliminated axial float and circular runout, has improved the service life of mechanical seal.
5, being positioned at the position that reversing handle 15 on the transfer valve 4 hinge plates 14 is in the left side is the slurrying position; Start running back adds additive, cement; After the ratio of mud reaches requirement in the main tank body, remained in operation 1～3 minute, slurries are stirred; At last reversing handle is pulled the plasma discharge position to the right, can slurries in the main tank body be discharged through grout outlet 9.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
