The automobile-used novel lower apparatus for ash of a kind of cementing concrete
Technical field
The utility model relates to coal seam, colliery pneumatic drill and adopts field, and particularly the automobile-used lower apparatus for ash of a kind of colliery coal seam gas-solid well, is applicable to apparatus for ash under the various types of cementing trucks of coal bed gas.
Background technology
In the mining operations of colliery coal bed gas, all use oil field oil, gas cementing concrete truck carries out well cementing operation, this lower apparatus for ash complicated structure, when operation, artificial intensity is larger, processing cost is high.In addition, former lower apparatus for ash, after major part is used at the scene and goes wrong, operative employee substantially all lower apparatus for ash in normally open, utilize the Hand-operated butterfly valve of former on-off action to control by rule of thumb lower grey amount.
Utility model content
The purpose of this utility model is to adapt in order to provide the lower apparatus for ash that the design of coal bed gas well cementing operation feature adapts to the coal bed gas cementing concrete truck use brief introduction type of colliery coal-bed gas exploitation feature.
The automobile-used novel lower apparatus for ash of a kind of cementing concrete, comprises the upper grey pipeline, Hand-operated butterfly valve, union head and the worm gear butterfly valve that set gradually, and the inside between every two devices is and communicates; Concrete grey enters in described lower apparatus for ash by described grey pipeline, and described Hand-operated butterfly valve is an overall switch, the quantity of the number of turns control concrete grey circulation that described worm gear butterfly valve rotates by worm screw; Between described Hand-operated butterfly valve and described worm gear butterfly valve, be provided with a union mouth, carry concrete grey by described union mouth simultaneously.
This device also comprises high energy mixers, water-line, the mixed slurry of secondary manifold, the first centrifugal pump, the second centrifugal pump and agitator tank; Concrete grey is delivered in described high energy mixers by described lower apparatus for ash, described the first centrifugal pump is delivered to water in described high energy mixers by described water-line, water and concrete grey enter described agitator tank by described high energy mixers, and the mixed slurry of described secondary manifold is connected with described agitator tank by described the second centrifugal pump.
Concrete grey is delivered in described high energy mixers by described lower apparatus for ash, described the first centrifugal pump is delivered to water in described high energy mixers by described water-line, water and concrete grey enter described agitator tank by described high energy mixers, and the mixed slurry of described secondary manifold is connected with described agitator tank by described the second centrifugal pump.
The beneficial effects of the utility model:
1, apparatus for ash under the utility model, its project organization is simple, volume is little, lightweight, is easy to manufacture, and is convenient to for cementing concrete truck.
2, the utility model mainly adopts butterfly valve to control, and has solved conventional ash discharging valve, uses effort and is not easy the problems such as replacing.
3, apparatus for ash under the utility model, a multi-functional peep hole is left in centre, can use as upper ash mouthful for subsequent use, also can be used as washout hole and uses, thereby adapt to various well cementing operation requirements.
Brief description of the drawings
Fig. 1 is lower apparatus for ash detailed structure view;
Fig. 2 is the utility model entirety principle schematic;
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
Please refer to Fig. 1, Fig. 1 is lower apparatus for ash detailed structure view described in the utility model.The automobile-used novel lower apparatus for ash 1 of a kind of cementing concrete, comprises upper grey pipeline 1-1, the Hand-operated butterfly valve 1-2, union head 1-3 and the worm gear butterfly valve 1-4 that set gradually, and the inside between every two devices is and communicates.
Concrete grey enters into 1 li of lower apparatus for ash by upper grey pipeline 1-1 (material is rubber tube), and first Hand-operated butterfly valve 1-2 plays the effect of an overall switch, the quantity of the number of turns control concrete grey circulation that worm gear butterfly valve 1-4 rotates by worm screw.Between Hand-operated butterfly valve 1-2 and worm gear butterfly valve 1-4, be provided with a union mouth 1-3, this union mouth 1-3 not only can be used for carrying concrete grey simultaneously, and can be used as the peep hole of a cleaning.
Please refer to Fig. 2, the utility model overall work principle schematic.The automobile-used novel lower apparatus for ash of cementing concrete described in the utility model, also comprises high energy mixers 2, water-line 3, the mixed slurry of secondary manifold 4, the first centrifugal pump 5, the second centrifugal pump 6 and agitator tank 7.The first centrifugal pump 5 is connected with high energy mixers 2 by water-line 3, and high energy mixers 2 is connected with agitator tank 7 and the mixed slurry of secondary manifold 4 respectively, and the mixed slurry of secondary manifold 4 is connected with agitator tank 7 by the second centrifugal pump 6.
When the work of this device, lower apparatus for ash 1 is delivered to concrete grey in high energy mixers 2 by certain amount, the first centrifugal pump 5 is delivered to water in high energy mixers 2 by water-line 3, high energy mixers 2 can be adjusted the amount that water enters, adjusting to a certain amount of concrete grey in conjunction with lower apparatus for ash 1 enters together in agitator tank 7 and stirs, can cement paste in agitator tank 7 be turned back in high energy mixers 2 through the mixed slurry of secondary manifold 4 by the second centrifugal pump 6 if the density of mixing does not for the first time reach requirement, then add appropriate ash or water and starch through row secondary is mixed.
