The characteristics of present embodiment are:
1, mixing sand tank 5 adopts anti-spilled design as shown in Figure 2: the jar as mixing sand tank 5 can reflux along exceeding upper end 50mm, mixing sand tank 5 upper edges are welded with acid solution overflow line 9, acid solution overflow line 9 direct blowdowns when the acid solution that is in an emergency is down overflowed, hurt sb.'s feelings for circular-arc preventing in a jar edge.
2, mixing sand tank 5 adopts closed design as shown in Figure 3, as sealing form cover plate such as safety viewfinder among Fig. 3 15 and the illumination form 17 that tempered glass makes is housed at the top of jar, can outside jar, observe the height of tank level at any time, and can prevent that acid solution from sputtering.Sand grains in two sand inlets 16 and two sediment transport spiral sand exports 6 is by the acidproof rubber water conservancy diversion cover of tubular closed communication, can reduce acid gas and mouthful overflow from going into jar of 2 sediment transport spirals, can make sand grains enter mixing sand tank 5 smoothly again.
3, reduce to stir the design that mulling liquid produces foam: as being equipped with 1 at the tank skin place on mixing sand tank 5 tops " froth breaking playpipe 10; be uniformly distributed with several apertures on the pipeline of froth breaking playpipe 10; they are staggered; the aperture is 1mm; froth breaking playpipe 10 is communicated with the intake of mixing sand tank 5, because mixing sand tank intake 13 acid solutions have pressure, foam smashed so the liquid of the aperture of froth breaking playpipe 10 ejaculation flows.And the interface of froth breaking playpipe 10 introduces through flow meter metering back from the solution feed pump outlet side, so both can not influence the feed flow metering, also can spray the purpose that reach the elimination foam by aperture.
4, the realization liquid level is controlled automatically: be fixed with ultrasonic detector at the mulling tank body by flange, send ripple by the ultrasonic detector that is contained on the body to liquid level during work, the current signal of output 4～20mA, send computer control to, control automatically controlled Variable plunger pump and drive the suction motor by potentiometer, rotating speed by the control motor is controlled the suction pump delivery, enters the clear water discharge capacity of mixing sand tank 5 with control.This control system can guarantee that the mixed liquor in the mixing sand tank 5 changes within the limits prescribed, reaches neither excessive and does not find time again, realizes automatic/hand control sand concentration and the metastable control function of liquid level.Maximum functional flow: 6m3/min (acid solution); Maximum sediment transport amount 〉=2 sides/minute.
5, the acid gas that produces in the whipping process is reclaimed design: at the top of mixing sand tank 5 acid gas suction line 4 is housed and connects acid gas suction pump 3, the acid gas that acid solution in the jar is mixed gas that afterreaction produces and volatilization is extracted in the container acid gas neutralizing tank 1 that fills NaHCo3 by acid gas suction line 4, acid gas suction pump 3, acid gas discharge pipe 2, prevents contaminated environment and to people's injury.The power supply of pump is 24V, and power is 1.5kW.
6, the storage of emergent goods and materials: the stainless cylinder of steel that the acid gas neutralizing tank of installing on acid proof truck-mounted blender car body 20 is 1 50 liters is used for depositing concentration and is 10% NaHCO3 solution.The material of water-feeding system, hybrid system and discharge system all adopts the acid-proof material 304L stainless steel of high-quality among the embodiment.
7, go up water (acid) and left and right sides straining function about fracturing blender truck possesses.
Need to prove, be not described in detail parts in the present embodiment to the greatest extent, belong to outsourcing part, do not do superfluous chatting at this.And present embodiment only is used to illustrate the present invention, is not limited to practical range of the present invention.
The course of work of the present invention is: at the scene in the application process, suction pump by fracturing blender truck is put on the various additives mixing that the next grains of sand and liquid additive pump and dry powder additive infusion are gone into the acid solution suction mixing sand tank and the sediment transport spiral that configure, stir (airtight for preventing the acid solution mixing sand tank that splashes by the impeller in the mixing sand tank, have only sand inlet relative with the dry powder additive mouth airtight, increased the envelope that acid-proof splashes at these two mouths; Mixing sand tank sealing back crossover is dark, for guaranteeing a jar intraoral illumination, lighting device has been installed in mixing sand tank; For preventing acid mist pollution environment, etching apparatus and injury operating personnel, the acid mist neutralising arrangement has been installed on mixing sand tank), fully mix the back and discharge by discharging sand pump, give the fracturing unit truck feed flow.The ratio of the liquid level of whole system, suction, discharge discharge capacity, sediment transport ratio and various additives is accurately controlled by computer.Finish accurate acid solution pressure break.
