Code name implication among the figure: 1-suction attachment device; The 2-header; The 3-centrifugal pump; The 4-mixing drum; 5-1,5-2,5-3,5-4,5-5-pneumatic operated valve; One group of 6-manifold; Two groups of 7-manifolds; Three groups of 8-manifolds; Four groups of 9-manifolds; 10-communicating pipe; The 11-pneumatic operated valve; 12-mixing drum intake duct; 13-mixing drum discharge line; The 14-by-pass line; 1 '-discharge piecing devices.
The specific embodiment
Referring to Fig. 1: a kind of pressure break fracturing blender truck closed type grouping sucks the exhaust manifold system, mainly bysuction attachment device 1, discharge piecing devices 1 ',header 2 and mixingdrum 4 and form.There are mixingdrum intake duct 12 and mixingdrum discharge line 13 in mixingdrum 4 both sides, and mixing drum intake duct and discharge line and the by-pass line 14 that is connected this pipeline enclosure are respectively equipped with pneumatic operated valve 11, are used to control the circulation path whether fracturing fluid add sand and select; Sucking, discharge piecing devices (1,1 ') is connected on theheader 2,header 2 is through 10 closed linking to each other of communicating pipe, adopt flange that pneumatic operated valve 5 is connectedheader 2 and on communicatingpipe 10, realize the unlatching of pneumatic operated valve 5 or close that by operation control pneumatic operated valve (5-1,5-2,5-3,5-4,5-5) will suck, discharge piecing devices (1,1 ') andheader 2 divides into groups to separate; Suction, discharge piecing devices (1,1 ') andheader 2 thereof are arranged on the fracturing blender truck both sides,suction attachment device 1 is connected with frac tank, discharges piecing devices 1 ' and is connected with the pressure break pump truck, and every set of joints device is a plurality of joints,header 2 is around vehicle body close arrangement, structure smoothness; Like this, the fracturing fluid of frac tank is throughsuction attachment device 1 andheader 2 or communicatingpipe 10 flow tocentrifugal pump 3,centrifugal pump 3 is pumped to mixingdrum 4 with fracturing fluid, drains into the pressure break pump truck alongheader 2 or communicatingpipe 10 with discharge piecing devices 1 ' then behind mixingdrum discharge line 13.
Header 2 of the present utility model and communicatingpipe 10 are the closed manifold system that pneumatic operated valve 5 groupings are isolated, has the function that grouping sucks, discharges, can realize that three groups suck one group of discharge, two groups and suck two groups of discharges, two groups suck one group of discharge, one group sucks one group of multiple compound mode such as discharge, satisfies the demand of different constructions; Possess suction, discharge dual-use function, both can be used for sucking fracturing fluid, can be used for discharging fracturing fluid again; In addition, also possess the function that many groups suck simultaneously, satisfy the feed flow requirement of extensive sand fracturing construction.
Below be several packet mode of the present utility model: onegroup 6 of manifold, two group 7 of manifold, manifold suck fracturing fluid for fourgroup 9, close pneumatic operated valve 5-1,5-4, open pneumatic operated valve 5-2,5-3,5-5, and manifold is discharged fracturing fluid for threegroup 8; Two group 7 of manifold, threegroup 8 of manifold, manifold suck fracturing fluid for fourgroup 9, close pneumatic operated valve 5-2,5-5, open pneumatic operated valve 5-1,5-3,5-4, and manifold is discharged fracturing fluid for onegroup 6; Onegroup 6 of manifold, manifold suck fracturing fluid for two group 7, close pneumatic operated valve 5-1,5-3, open pneumatic operated valve 5-2,5-4,5-5, and threegroup 8 of manifold, manifold are discharged fracturing fluid for fourgroup 9; Two group 7 of manifold, manifold suck fracturing fluid for fourgroup 9, close pneumatic operated valve 5-2,5-4, open pneumatic operated valve 5-1,5-3,5-5, and onegroup 6 of manifold, manifold are discharged fracturing fluid for threegroup 8; Onegroup 6 of manifold, manifold suck fracturing fluid for two group 7, close pneumatic operated valve 5-1,5-3,5-4, open pneumatic operated valve 5-2,5-5, and manifold is discharged fracturing fluid for threegroup 8; Two group 7 of manifold, manifold suck fracturing fluid for fourgroup 9, close pneumatic operated valve 5-1,5-2,5-4, open pneumatic operated valve 5-3,5-5, and manifold is discharged fracturing fluid for threegroup 8; Manifold sucks fracturing fluid for two group 7, closes pneumatic operated valve 5-1,5-2,5-3,5-4, opens pneumatic operated valve 5-5, and manifold is discharged fracturing fluid for threegroup 8; Suction of the present utility model, discharge grouping are not limited to above-mentioned several, can also realize other suctions, discharge combination.
