The end face of described minute water thimble is a conical structure, and the vertical distance between the conical surface of the tube wall bottom of upper hose water side and branch water thimble is 5～10mm.
The described inwall of grey bend pipe, injection bend pipe and housing, and on the inner and outer wall of lining, all be coated with and be coated with the Talide layer.
Coating Talide layer makes the case hardness of each pipeline inner wall reach HRC65～more than 70, improved abrasion resistance, thereby has prolonged application life.
The thickness of described Talide layer is 0.2～0.5mm.
The operating principle of the utility model:
In the course of normal operation, the gas control butterfly valve is in closed condition, according to construction cement slurry density requirement, controls concrete grey amount and the clear water amount that gets into high energy mixers well.After press water gets into upper hose; Branch water thimble through the upper hose bottom is dispersed into fan-shaped fast; Concrete grey is fed into grey bend pipe and gets into housing through spraying bend pipe and lining through pressure fan wind; In housing, realize mixed once, get into mixed stock tank after the mixed cement paste and fully mix processing with clear water.
When needs secondary mixing ash; The gas control butterfly valve is opened, and secondary mixing buck mud is through charge pump, in the pumping of secondary mixing ash pipe gets into housing; According to the requirement of construction cement slurry density; Control concrete grey amount and the clear water amount that gets into high energy mixers well, and realize mixing once more of cement paste, get into mixed stock tank afterwards and fully mix processing through the tapering annular space that forms between sleeve and the housing.
The beneficial effect that the utility model had is: the oil gas field well cementation, simplifies the structure through changing the secondary mixing ash pipe into the individual tubes line structure with high energy mixers, has improved the flow velocity of secondary mixing buck mud entering housing; And avoided clogging, divided the water thimble to be fixed on the upper hose, no longer needed manual adjustment; Reduced labour intensity, the error that possibly occur when having avoided manual adjustment has guaranteed flow stability; Improved flow velocity, improved mixed slurry effect, at each inside pipe wall coating Talide layer; Improve abrasion resistance, thereby prolonged application life.
