Abstract
The utility model relates to a jet type mixer which can adjust flux, which comprises a plant powder input port, a mixing cavity and an inlet for transporting water into the mixing cavity. The utility model is characterized in that: a spraying head is arranged in the axial direction of the mixing cavity, a water pressure cavity is arranged between the side wall of the spraying head and water inlet, a piston which is fixed with the spraying head is arranged above the water pressure cavity, another pressure cavity corresponding to the water pressure cavity is formed between the upper surface of the piston, the side wall and cavity of the spraying head, the pressed area of the upper surface of the piston is larger than that of the lower surface, a flow adjusting opening for pouring water into the mixing cavity is arranged between the outer wall of the lower end of the spraying head and the inner wall of the upper end of the mixing cavity. The utility model has the advantage of effectively preventing the caking of plant powder.
Description
Technical field
The utility model relates to a kind of ejection-type blender of automatic adjusting flow, mainly is used to mix your powder of guanidine or other materials in the petroleum drilling and mining industry, injects the fracturing fluid of down-hole so that be mixed at oil gas well scene.
Background technology
Preparing of the fracturing fluid method by mixing guanidine that powder or other materials has come out nearly 50 years.Fracturing fluid is sent to proppant (as sand) in the oil gas well, is split in the stratum, and purpose is to improve crude oil or gas production.In the past, your fracturing fluid of guanidine is defective in quality, promptly occurs tangible guanidine that powder caking phenomenon in your fracturing fluid of guanidine.These cakings have not only weakened permeability, and cause the reduction of fracturing fluid viscosity.The reduction of viscosity is because colloid can not melt well mutually with liquid.For the high-quality fracturing fluid that is mixed out, the fracturing fluid that does not promptly have caking and mix once adopted many methods.For example filter caking with filter screen; With pulverizing and cutting equipment caking is broken up; With chemical substance the dry powder particulate is wrapped up with the hydration process that slows down, thereby stop caking or the like.All these methods not only can increase of the fracturing fluid cost, and will increase expensive equipment according to operation.Therefore also just increase the cost of well cementation, and caused product oil or gas expensive more.The problem that existing standard mixer exists is that the structure of shower nozzle or ejector is generally fixing, that is shower nozzle is uncontrollable, if actual flow is not equal to desired desirable flow, when your powder of guanidine contacts with water, just can not make it fully wetting, so just formed caking.
The utility model content
Technical problem to be solved in the utility model is: a kind of ejection-type blender of automatic adjusting flow is provided, and it regulates flow by a shower nozzle that can relatively move, and actual pressure is remained be mixed required desired pressure, thereby stops caking.The technical scheme that solves this technical problem is: a kind of ejection-type blender of automatic adjusting flow, comprise: plant powder input port, hybrid chamber and to the import of hybrid chamber transporting water, it is characterized in that: along the shower nozzle that is axially arranged with of mixing chamber, it between the sidewall of shower nozzle and the water inlet hydraulic pressure chamber, above the hydraulic pressure chamber, be provided with the piston that fixes with shower nozzle, constitute and corresponding another pressure chamber in hydraulic pressure chamber between piston upper surface and shower nozzle sidewall and the cavity, the compression area of piston upper surface forms the Flow-rate adjustment mouth that injects water to hybrid chamber greater than its soffit between the inwall of the lower end outer wall of shower nozzle and hybrid chamber upper end.
And the lower end outer wall of shower nozzle is taper seat, and the outer wall of piston is provided with sealing ring.
And the top of mixing chamber is provided with end cap and partly stretches into the interior stop bolt of axial groove of shower nozzle.
And end cap and stop bolt constitute one, are respectively equipped with sealing ring between end cap and shower nozzle and the mixing chamber.
In the technical program, preset a constant lasting reference pressure (hydraulic pressure or air pressure) for the pressure chamber of piston top according to desired pressure, so it is descending and close the Flow-rate adjustment mouth that piston is promptly pushing away shower nozzle, when from water inlet injection clear water, the pressure of setting up in the hydraulic pressure chamber is that pushing tow piston and shower nozzle is up, thereby opens the Flow-rate adjustment mouth, meanwhile, the current that inject produce negative pressure above the Flow-rate adjustment mouth of shower nozzle, make the plant powder of suction mixed at hybrid chamber and water through shower nozzle.Like this, under the acting in conjunction of reference pressure and water injection pressure, order about piston and shower nozzle moves up and down, make the Flow-rate adjustment mouth keep constant be mixed desired pressure and flow.The technical program can prevent plant powder caking effectively.
Description of drawings
Accompanying drawing is the sectional view that reflects that on the whole the utility model constitutes.
The specific embodiment
With reference to accompanying drawing, ejection-type blender described in the utility model, comprise: plant powder input port 1, hybrid chamber 16 and to the import of hybrid chamber 16 transporting water, it is characterized in that: be axially arranged with shower nozzle 13 along mixing chamber 15, be hydraulic pressure chamber 12 between the sidewall of shower nozzle 13 and the water inlet 11, above hydraulic pressure chamber 12, be provided with the piston 9 that fixes with shower nozzle 13, constitute and hydraulic pressure chamber 12 corresponding another pressure chambers 8 between piston 9 upper surfaces and shower nozzle 13 sidewalls and the cavity 15, the compression area of piston 9 upper surfaces forms the Flow-rate adjustment mouth 14 that injects water to hybrid chamber 16 greater than its soffit between the inwall of the lower end outer wall of shower nozzle 13 and hybrid chamber 16 upper ends.Further technical scheme can be: the lower end outer wall of shower nozzle 13 is taper seat, and the outer wall of piston 9 is provided with sealing ring 10.Can also be: the top of mixing chamber 15 be provided with the stop bolt 2 in the axial groove 3 that end cap 4 and part stretch into shower nozzle 13, rotates to prevent shower nozzle 13.And end cap 4 and stop bolt 2 constitute one, are respectively equipped with sealing ring 5,6 between end cap 4 and shower nozzle 13 and the mixing chamber.
During work, to the recommendation of the default reference pressure of pressure chamber be: 7～9kg/cm
2, this pressure can inject from the aperture 7 of cavity 15.
