Description
Technical field
The utility model relates to a kind of axial-flow type high energy mixers, and it belongs to the oil field equipment technical field.
Background technology
Because the application of reinforcing oil well equipment now more and more widely, and more and more users tends to possess the cementing equipment of bivariate control system, and it is had relatively high expectations to control water and control ash.But existing axial-flow type bivariate high energy mixers exists blender to return water, row's problems such as flying dust is untimely, has influenced the development of bivariate control system.
The utility model content
The utility model to blender in the prior art exist row's flying dust ability relatively poor with the deficiency of returning water, a kind of axial-flow type high energy mixers is provided.
The technical scheme that the utility model solves the problems of the technologies described above is following:
A kind of axial-flow type high energy mixers comprises installing plate, on the said installing plate diffusion chamber is installed; Said diffusion chamber is upper coarse and lower fine structure; Top in the said diffusion chamber is provided with liner, and said liner top is provided with down grey liner, and said down grey liner top is provided with the dry ash inlet, and side is provided with water inlet pipe; Said diffusion chamber outside is provided with inlet pipe, and the below is provided with guide vane and back taper, and said back taper is located at the below of guide vane.
Compared with prior art, the beneficial effect of the utility model is: the structure design of liner has realized that water inlet divides three layers, and oblique spraying into avoided Central Collisions to splash, and prevents to return water, and increases vacuum band ash ability, strengthens and mixes the slurry effect, makes current more orderly; With the cavity of diffusion chamber from up-thin-low-thick be optimized for upper coarse and lower fine; Reduced the diameter of cabinets cavity; Reduced the flowing space of the volume and the secondary mud of cabinets cavity greatly; Under the effect of damming of pressurization baffle plate, make circulating mud form bigger jet power simultaneously, the band ash effect of secondary mud is more obvious; The upper taper structure of back taper is removed, and it is comparatively simple that the back taper overall structure becomes, and mud can flow out from diffusion chamber is inner more smoothly, avoided causing the mud accumulation of diffusion chamber bottom and depositing ash after the long-term operation.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, the outside installing plate below of said diffusion chamber and guide vane is provided with protective cover.
Further, the installing plate top that said protective cover is corresponding is equipped with the flying dust bend pipe.
Further, be provided with the pressurization baffle plate between said diffusion chamber and the liner.
Further, said guide vane is a flat structure.
Adopt the beneficial effect of above-mentioned further scheme to be: the setting of protective cover, stopped splashing of mud after mixing, have the gathering flying dust simultaneously, strengthen the effect of row's flying dust effect; The setting of flying dust bend pipe is guided to flying dust outside the slurry mixing tank, and increases turning gland, to adapt to the adjustment of wind direction, has solved and has assembled flying dust in the slurry mixing tank, and the problem with operation is observed in influence; The setting of pressurization baffle plate has increased secondary mud expulsion pressure, plays the effect of good band ash, has strengthened mixed slurry effect.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Dry ash inlet in the drawings, 1; 2, following grey liner; 3, liner; 4, inlet pipe; 5, pressurization baffle plate; 6, installing plate; 7, diffusion chamber; 8, protective cover; 9, guide vane; 10, back taper; 11, water inlet pipe; 12, flying dust bend pipe.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
A kind of axial-flow type high energy mixers comprises installing plate 6, on the said installing plate 6 diffusion chamber 7 is installed; Said diffusion chamber 7 is upper coarse and lower fine structure; Top in the said diffusion chamber 7 is provided with liner 3, is provided with pressurization baffle plate 5 between said diffusion chamber 7 and the liner 3; Said liner 3 tops are provided with down grey liner 2, and said grey liner 2 tops down are provided with dry ash inlet 1, and side is provided with water inlet pipe 11; Said diffusion chamber 7 outsides are provided with inlet pipe 4, and the below is provided with guide vane 9, the back taper 10 of flat structure, and said back taper 10 is located at the below of guide vane 9; Said diffusion chamber 7 is provided with protective cover 8 with guide vane 9 outside installing plate 6 belows; Said protective cover 8 corresponding installing plate 6 tops are equipped with flying dust bend pipe 12.
The utility model is when making, and protective cover is the rubber material, increases the height of protective cover 8, has more effectively stopped splashing of mud after mixing, helps assembling flying dust and discharges from flying dust bend pipe 12; Increase the height of grey liner 2 down, thereby extended the length that time grey liner 2 embeds in liner 3, the height increase of following grey liner 2 more effectively stops injection from liner 3 and the four sides sputter of the clear water that goes out.
In use, the utility model is installed and fixed through installing plate 6 and slurry mixing tank each other.Current get into and form jet water course by water inlet pipe 11, arrive inner chamber through liner 3.At first jet water course converges with the dry ash that from following grey liner 2, gets off, and at this moment, after the adjustment of the flow direction of current through liner 3 and following grey liner 2, the band ash of performance optimum acts on and can not return water; Current and dry ash converge that continued is dirty to be converged with the secondary cycle mud that flows into from inlet pipe 4 tangentials then, and the cement paste after converging mixes in diffusion chamber 7; The cement paste that mixes at last flows out in the entering slurry mixing tank through the back taper 10 of diffusion chamber 7 bottoms.When cement paste mixed in diffusion chamber 7, the flying dust of generation was discharged slurry mixing tank through flying dust bend pipe 12 under the gathering of protective cover 8.
