The utility model includes a slurry mixing pool, a mixer, an ash-in water collector, an ash adjusting valve, a water adjusting plate, a guide device, an adjutage and a damper. The slurry mixing pool is provided with a refluxing mixer whose top is provided with the ash-in water collector on which is provided with the ash adjusting valve; the water adjusting plate is arranged below the ash-in water collector; the guide device is arranged below the ash-in water collector; the middle part of the refluxing mixer is provided with the adjutage and the lower part of the refluxing mixer is provided with the damper. The utility model which adopts the spraying rotary flow principle has an extremely powerful mixing capacity and can reach perfect mixing water-slurry and perfect density control.
Description
Technical field
The utility model relates to a kind of mixing apparatus, a kind of specifically mixed slurry blender.
Background technology
The reinforcing oil well operation needs big flow, high density, evenly continuous, stay-in-grade cement mortar is mixed, blender is mounted on the cementing truck equipment that clear water and dry cement is mixed into cement mortar, and dissimilar cementing trucks can use the hybrid system of different structure.The subject matter that existing many spiral cases blender in use exists is to spray fluid jet power in the spiral case rotational flow to weaken, and is not easy and the cement rapid mixing; Backflow mud directly enters injection line and the next clear water of jet pump enters spiral case simultaneously, increases the weight of the spiral case burden again, makes to mix to produce grey piece; Mix uneven mud again less than stirring, cause the mud that mixes out continuously inhomogeneous, speed is slow, and proportion does not reach requirement.
The utility model content
The purpose of this utility model provides a kind of secondary back and mixes the slurry blender, and to solve the rapid mixing that is difficult for that existing many spiral cases blender exists, the mud that mixes out continuously is inhomogeneous, speed slow, proportion does not reach the problem of requirement.
The utility model comprises mixed stock tank, blender; It also comprises ash charge water collector, mix ash valve, water transfer plate, air deflector, playpipe, damper, mix stock tank and be provided with the backflow blender, backflow blender top is provided with the ash charge water collector, the ash charge water collector is provided with mix ash valve, ash charge water collector bottom is provided with the water transfer plate, is provided with air deflector below the water transfer plate; Backflow blender middle part is provided with playpipe, and backflow blender bottom is provided with damper.
The utility model has adopted injection rotational flow principle, has very strong mixing ability, can reach desirable mix cement slurry and desirable density control.Whole mixed process can be carried out continuously and stably, and it is 0～1.9 cubic metre of per minute that standard is mixed slurry speed.Every cubic centimetre of density 0～2.2 gram.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model comprises mixed stock tank 10, blender, ash charge water collector 1, mix ash valve 2, water transfer plate 3, air deflector 4, playpipe 5, damper 7, mix stock tank 10 and be provided with backflow blender 6, backflow blender 6 tops are provided with ash charge water collector 1, ash charge water collector 1 is the inlet of clear water and concrete grey, the center is the passage of concrete grey, periphery is accumulated the clear water of certain pressure, ash charge water collector 1 is provided with mix ash valve 2, mix ash valve 2 is by 6, and " butterfly valve is finished, and control mixes slurry speed and the required ash amount of mud density.Ash charge water collector 1 bottom is provided with water transfer plate 3, is provided with air deflector 4 below the water transfer plate 3; Backflow blender 6 middle parts are provided with playpipe 5, and backflow blender 6 bottoms are provided with damper 7.Backflow blender 6 is circular cylinder bodies, and mixed once and secondary back are blended in this and compile, and produces downward tangentially rotatablely moving.The effect of damper 7 is that the downward mud that tangentially rotatablely moves is stoped and reverse recoil at once, to increase the uniformity of mud.Mixing stock tank 10 has an outlet, and finished product mud is discharged shunting for pump.
Ash charge water collector 1 bottom margin has 16～20 spilled water holes corresponding with 16～20 water holes on the described water transfer plate 3, the water transfer plate is rotated along the axle center by operating desk control, the area of spilled water hole and water hole is increased or dwindle, the clear water that makes the ash charge water collector accumulate pressure sprays in the desired amount.Air deflector 4 is provided with 16～20 skewed slots 12 with corresponding 45～65 degree of 16～20 spilled water holes of ash charge water collector 1 bottom vertically, and the water that water transfer plate 3 is come forms a clear water barrier, and concrete grey becomes cement mortar in this barrier.
Playpipe 5 is 2 groups, tangentially is symmetricly set on the side of backflow blender 6, is the cement mortar of mixed once tangentially to be rotated ejection by certain angle carry out secondary back and mix.
Mix in the stock tank 10 and be provided with agitator 9.Agitator 9 is that the mud that will mix carries out last stirring, makes mud more even.Agitator has four blades of a main shaft, inclination be installed in the blender side, drive by fluid motor.
The operation principle that secondary back mixes the slurry compounder systems is as follows: jet pump is input into clear water the clear water inlet of ash charge water collector 1, the clear water that enters ash charge water collector 1 makes a certain amount of clear water with different angles directive center through air deflector 4 under the adjustment of water transfer plate 3, forms a clear water barrier.The unloading vehicle that is fully loaded with concrete grey this moment continuously is sent to dry cement the ash charge mouth on mix ash valve 2 tops; Concrete grey enters ash charge water collector 1 by required amount under the control of mix ash valve 2, the cement that enters ash charge water collector 1 has produced with clear water in the process of passing through that clear water barrier and mixed, and has formed mud liquid.At this moment, the gas that is brought by unloading vehicle separates in current the mixing with mud liquid, and gas is discharged through waste gas outlet 11 on buffering current stabilization circle 8 tops, significantly reduces the content of gas in the cement mortar.Mud liquid enters under damper 7 effects and mixes stock tank 10, is further stirred mixed once that Here it is by agitator 9.
By reflux pump this slurries are extracted out and to be carried out the proportion that secondary back can improve mud.In the continuous operation of mixed once, reflux pump is extracted slush pump out and is delivered to playpipe 5 from mix stock tank 10, slurries are ejected in from playpipe 5 and have formed the tangential swirl motion the backflow blender 6, slurries carry out tangential swirl with the new slurries that produce under the clear water barrier in this motion mixes, the gas of new slurries is discharged through waste gas outlet 11 on buffering current stabilization circle 8 tops, mud liquid enters under damper 7 effects and mixes stock tank 10, further stir by agitator 9, after treating that density reaches requirement, by reflux pump these slurries are extracted out again.Here it is, and secondary mixes, and just secondary back mixes slurry.
Mud reaches requirement density in mixed stock tank 10, and when mixed stock tank was also filled, density mud up to standard was extracted the back out by reflux pump and divided two-way to pump, and one the tunnel sends into big pump carries out well cementing operation, and another road is pumped into playpipe 5, carries out above-mentioned work.Whole mixed process can go on continuously and stably, and it is 0～1.9 cubic metre of per minute that standard is mixed slurry speed.Every cubic centimetre of density 0～2.2 gram.
