As the Pneumatic conveyer and diffuser or out connector between sandpipe.
Beneficial effects of the present invention: suction sand energy conserving system of the invention original scheme avoid waterpower hit on the basis of,
Pneumatic conveyer is added on diffuser or out sandpipe, is entered by the pressure-air that Pneumatic conveyer exports swollen in pipeline
Swollen acting pushes sand aqueous mixtures quickly to flow, to guarantee efficiency of shaking out.
Detailed description of the invention
A specific embodiment of the invention is described further with reference to the accompanying drawing.
Fig. 1 is suction sand energy conserving system structural schematic diagram of the invention；
Fig. 2 is Pneumatic conveyer scheme of installation of the invention；
Fig. 3 is jet ring front view of the invention；
Fig. 4 is jet ring sectional view of the invention.
Specific embodiment
As shown in Figure 1, adding the suction sand energy conserving system pushed away, including jet element 1, vacuum for a kind of high-pressure pneumatic of the invention
Room 2, compressed pipe 4, diffuser 5, goes out sandpipe 6, pressure piping 7 at sand-feeding tube 3；Jet element is mounted in vacuum chamber 2 and spray nozzle part
The outlet end of positive vacuum chamber 2, the input end of jet element are docked in the outlet of part with pressure piping 7, the outlet of the vacuum chamber 2
End docked with one end of compressed pipe 4, the other end of compressed pipe 4 is docked with the small end of diffuser 5, the big end of the diffuser 5 and
Sandpipe 6 docks out, and sand-feeding tube 3 is mounted on vacuum chamber 2 and the jet direction of the center line of sand-feeding tube 3 and the vacuum chamber 2
Angle be 30 °~35 °；Preferably 33 ° of golden section angles keep the conjunction speed range of two fluids farthest using this angle,
Reduce waterpower as far as possible and hit loss, to improve the efficiency of vacuum chamber system.
The main improvement of the technical program is that suction sand energy conserving system of the invention further includes Pneumatic conveyer 8, should
Pneumatic conveyer 8 is arranged on diffuser 5 or out sandpipe 6, the puff prot 81 of the Pneumatic conveyer 8 and diffuser 5 or
The inside connection of sandpipe 6 and direction go out the outlet side of sandpipe 6 out.On the basis of original scheme avoids waterpower from hitting, add
Pneumatic conveyer is entered swollen in pipeline on diffuser 5 or out sandpipe 6 by the pressure-air that Pneumatic conveyer 8 exports
Swollen acting pushes sand aqueous mixtures quickly to flow, to guarantee efficiency of shaking out.
As the first preferred embodiment of the technical program, the center line of 81 jet direction of puff prot with shake out
The center line of pipe 6 is in same plane and angle is 0 °~10 °, so that sand aqueous mixtures are directly toward under the action of pressure-air
Output flow.The center line of the center line of preferential 81 jet direction of puff prot and sandpipe 6 out is in same plane and angle is
5 °~10 °.Such as Fig. 2, Fig. 4.
In the installation position selection of Pneumatic conveyer 8, in addition to being installed on diffuser 5 or the out body portion of sandpipe 6,
It is also an option that being installed on the joining place of diffuser 5 with sandpipe 6 out, as shown in Figure 1.
As the another embodiment of the technical program, the center line of 81 jet direction of puff prot can also be set
For center line with sandpipe 6 out not in same plane, this setting can be that pressure-air acts on entire pipeline cross to the greatest extent
Sand aqueous mixtures on section make the sand aqueous mixtures on entire cross-section of pipeline generate rotation, rotation so that being more uniformly stressed
The benefit of the sand aqueous mixtures turned is first is that conveying speed can be improved, second is that can make sand water to the generation impact of entire cross-section of pipeline
Mixture cannot ensure that the unimpeded of entire pipeline in the generation deposition and fouling on cross-section of pipeline.
In addition, in the present embodiment, the puff prot 81 have it is multiple, as shown in Figure 3, Figure 4, multiple puff prots 81
It is distributed on jet ring 82, the jet ring 82 company between sandpipe 6 as Pneumatic conveyer 8 and diffuser 5 or out
Fitting guarantees that the pressure-air of puff prot 81 from diffuser 5 or out multiple positions output pressure-air of sandpipe 6 is surround, guarantees
Pressure-air acting is uniform, stable and efficient.
Meanwhile this programme still retains former scheme pressure piping 7 (water pump water outlet pipeline) and the selection of 6 diameter of sandpipe out.
1, the selection of the diameter of pressure piping 7 (water pump water outlet pipeline):
Pressure piping diameter phi D1 is determined according to pump capacity, lift, keeps pump discharge minimum to 2 on-way resistance of vacuum chamber,
Reduce unnecessary headloss, improves efficiency.
2, go out the selection of the diameter of sandpipe 6:
The selection of 6 diameter phi D2 of sandpipe out, with go out sand aqueous mixtures in sandpipe 6 flow velocity be greater than gravel subsidence velocity be
Principle makes larger gravel be unlikely to the blocking sandpipe that sinks.Sand efficiency is sent in raising.
3, the selection of length of tube is compressed:
The selection of 4 length L2 of compressed pipe, pumping fluid is from jet element 1 with velocities Vp and from sand-feeding tube 3 with speed V2 suction
After upper fluid passes through vacuum chamber 2 (suction chamber), two fluids is sufficiently mixed in compressed pipe 4 kinetic energy being fully converted into pressure energy
It is extruded in compressed pipe 4 with speed Vt as principle, reduces unnecessary kinetic energy rejection, improve system effectiveness.
4, the selection of 5 diffusion angle of diffuser and length:
The diffusion angle θ of diffuser 5 is no more than 11 degree according to hydrodynamics for principle, and length L3 is wanted meeting angle
It asks rear microcephaly's docking compressed pipe 4, major part to dock out sandpipe 6 and determine, prevents from reducing energy due to the excessive generation vortex of diffusion angle
Loss improves vacuum chamber efficiency.
The course of work of the technical program is high pressure water P1 (pressure), V1 (speed) 35m/s-65m/s, is sprayed from nozzle,
Negative pressure is formed in the Q chamber of vacuum chamber, speed is carried out in compressed pipe 4 with P2 (pressure), V2 (speed) from sand-feeding tube 3 by atmospheric pressure
Neutralization, with the extrusion of Vt speed, pressure enters by the pressure-air of Pneumatic conveyer 8 with P4 (pressure), V4 (speed)
Sandpipe 6 pushes sand aqueous mixtures to flow out sandpipe 6 out with P5 (pressure), V5 (speed) by pressure-air expansion working.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to above embodiment, as long as with
Essentially identical means realize that the technical solution of the object of the invention belongs within protection scope of the present invention.
