Description
Technical field
The utility model relates to mulling sledge, particularly a kind of novel mulling sledge.
Background technology
Along with the exploitation attention at home of shale gas, relevant equipment and technology application use more extensive, and wherein the application of continuous oil pipe operation technology is particularly outstanding.But the use of continuous oil pipe operation technology has a larger problem, namely current when this technology is used for the operation such as sandblasting cutting, acid fracturing supporting equipment be fracturing blender truck and fracturing unit truck, and coiled tubing self due to caliber less, the flow of use is also less (generally at 1m
3 '/ below min), and the flow of fracturing blender truck is very large (generally at 20m
3 '/ more than min).Therefore use fracturing blender truck not too to mate, cost is excessive.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides the novel mulling sledge that a kind of cost is low, easy to use and mulling is effective.
The purpose of this utility model is achieved through the following technical solutions: it comprises frame, described frame is provided with positive displacement pump, suction pumps, blending tank, for sand device, agitator is provided with in described blending tank, described suction pumps is connected with blending tank by pipeline, and suction pumps is provided with a feed water flow gauge with mixing on tank connected pipeline, described positive displacement pump is connected with bottom blending tank by pipeline, and positive displacement pump is provided with a sand pump pressure sensor with mixing on tank connected pipeline, the described port of export for sand device is positioned at blending tank entrance top, described is connected with a sand hopper for sand device arrival end, sand hopper is arranged in frame.
Described suction pumps is by imbibition motor control, and positive displacement pump is by discharge opeing motor control, and for sand device by supplying sand motor control, agitator is controlled by stirring motor.
Described is provided with a speed probe on sand device.
A mulling content gauge is provided with in described blending tank.
The utility model has the following advantages: mulling sledge of the present utility model, adopts four motors to drive suction pumps, positive displacement pump, sand deliverer and agitator respectively, makes mulling sledge easy to operate, ensure that the quality of sand-laden fluid simultaneously; During work, can continuous sand mixing, improve operating efficiency, save cost of production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
In figure, 1-suction pumps, 2-frame, 3-blending tank, 4-mulling content gauge, 5-sand hopper, 6-speed probe, 7-supplies sand device, 8-positive displacement pump, 9-sand pump pressure sensor, 10-feed water flow gauge.
Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, a kind of novel mulling sledge, it comprises frame 2, described frame 2 is provided with positive displacement pump 8, suction pumps 1, blending tank 3, for sand device 7, agitator is provided with in described blending tank 3, described suction pumps 1 is connected with blending tank 3 by pipeline, and the pipeline that is connected with blending tank 3 of suction pumps 1 is provided with a feed water flow gauge 10, feed water flow gauge 10 calculates discharge, so that control the liquid level in blending tank 3, described positive displacement pump 8 is connected with bottom blending tank 3 by pipeline, and the pipeline that is connected with blending tank 3 of positive displacement pump 8 is provided with a sand pump pressure sensor 9, by the pressure that sand pump pressure sensor 9 induces, reflect the concentration of sand-laden fluid, the described port of export for sand device 7 is positioned at blending tank 3 entrance top, described is connected with a sand hopper 5 for sand device 7 arrival end, sand hopper 5 is arranged in frame 2.
In the present embodiment, described suction pumps 1 is by imbibition motor control, and positive displacement pump 8 is by discharge opeing motor control, and for sand device 7 by supplying sand motor control, agitator is controlled by stirring motor.For controlling the rotating speed for sand device 7 further, for sand device 7 being provided with a speed probe 6, by rotating speed sensor 6, the rotating speed for sand device 7 being monitored, ensure that for sand device 7 even for sand, ensure that quality further.
In the present embodiment, be provided with a mulling content gauge 4 in blending tank 3, the liquid level in blending tank 3 monitored by mulling content gauge 4, then adjusts the flow of suction pumps 1 and positive displacement pump 8 respectively, the liquid level in blending tank 3 is remained in fixed interval.
The course of work of the present utility model is as follows: open imbibition motor, imbibition motor control suction pumps 1 feed liquor, then discharge is calculated by feed water flow gauge 10, the liquid level in blending tank 3 is made to reach specified altitude assignment, then discharge opeing motor control positive displacement pump 8 works, the liquid level in blending tank 3 is made to remain in fixing interval, when needs sand liquid, open for sand motor and stirring motor, by calculating the sand content (i.e. sand ratio) of liquid, control liquid inlet volume and enter sand amount, to reach the sand-laden fluid that operation needs, when not needing sand-laden fluid, stop for sand motor, agitator is rotated further, the grains of sand in mulling liquid drain only by time delay a few minutes, after operation completes, the sand removing hole of the lower end for sand device 7 is opened, reversely rotate for sand motor, clean getting rid of for the grains of sand in sand device 7.
