The pressure of nozzle place abrasive mixture is controlled by being added to the pressure on the carrier current.Under about 200,000,000 Pascals' very high pressure, water is can obviously compressed (approximately compressing 10%), so the water of about 5 liters is incorporated in the high-pressure bottle of 50 liters its pressure is increased to this operating pressure level, needs the regular hour and water is introduced pressure vessel.In the cutting operation of complexity, the delay of this time is unallowable.
The present invention aims to provide a kind of abrasive mixture pressure charging system.This system comprises a high-pressure bottle; One fexible film, this film form a film chamber in high-pressure bottle; One fluid provider under pressure; Described fluid provider is connected to described film chamber the inclusion in the film chamber is transported to the device of nozzle; One can be connected to the abrasive mixture source of supply of film chamber; Controlling the device of fluid pressure with the indoor pressure of control film away from the film side of film chamber.Pressure can be controlled to control when the abrasive mixture source of supply enters the film chamber at abrasive mixture, also can be by a spot of fluid being introduced a volume in film side away from the film chamber, it is controlled, this volume much smaller than the volume of film chamber improving the indoor pressure of film, the speed that the speed that its pressure improves can reach when fluid is directly introduced the film chamber.
Jockey preferably includes a jet pump, and the high pressure entry of jet pump links to each other with fluid provider, and its low-pressure inlet links to each other with the film chamber, and its outlet can be closed selectively.When port closing, this pump is delivered to the film chamber to fluid from fluid provider, and this measure can be used for the inclusion of film chamber is transported to nozzle.When outlet was opened, pump was from film chamber draw fluid, made it pass through outlet by force, and this measure can be used for ducted not from the abrasive material emptying of nozzle ejaculation.
Below in conjunction with accompanying drawing several examples of embodiments of the invention are described, in the accompanying drawing:
Fig. 1 is that different abrasive materials mixes the schematic diagram of supply system to Fig. 5;
Fig. 6, shown in 7,8 is the variation of the parts in the said system;
Fig. 9 is the schematic diagram of another supply system.
In Fig. 1, the abrasive material thin pulp is stored in the hopper 11.Carrier fluid (water) enters inlet 12 under pressure, this equipment makes abrasive mixture ejection from nozzle 13 under pressure.This equipment also comprises a high-pressure bottle 15 and a jet pump 16.Hopper is connected to pressure vessel by a transfer valve 20.One variable pressure source 17 is connected to balloon-like film 19 in the high-pressure bottle 15 by valve 18.Fluids in the source 17 since the existence of film 19 and not with high-pressure bottle 15 in inclusion directly contact.
The high pressure entry of jet pump 16 links to each other with inlet 12, and its low-pressure inlet then links to each other with the inside of high-pressure bottle 15 by a filter 21.Spray delivery side of pump and flow to nozzle 13 by a valve 22.Valve 23 and throttle 24 are connected to jet pump 16 arrives the abrasive mixture of nozzle 13 with control concentration with the form of bypass in parallel.One pipeline 25 the inside of high-pressure bottle 15 with link to each other from 12 the pipelines that enter the mouth to nozzle 13.
In use, make pressures cycle in the balloon-like film 19 by variable pressure source 17, thereby transfer valve 20 is opened, this moment, the abrasive material thin pulp was sucked up in the container 15 from hopper 11.When the indoor increased pressure of film, valve 20 cuts out, and turns back to hopper 11 to prevent abrasive material.When having had enough abrasive material thin pulps in the container 15, valve 18 cuts out, and make balloon-like film chamber keep swelling state, and valve 20 cuts out, and returns hopper to prevent thin pulp.
Pump lose to connect and to make fluid then 12 arrive container 15 through jet pump from entering the mouth thereby valve 22 is closed.Force the abrasive mixture in the container 15 to arrive nozzle 13 by pipeline 25.This flow can be stopped by closing the valves 14 in the fluid intake 12, perhaps makes it to stop by opening valve 22, but promptly stops and can make that balloon-like film chamber 19 is flat falls (losing heart) with the pressure in the reduction high-pressure bottle 15 by opening valve 18.
When being stopped when flowing, some abrasive mixtures will be stayed in the pipeline 25, wherein there are some to be discharged from, but when valve 22 is opened pump 16 operations, this pump 16 will be gone out fluid by filter 21 from container 15 suctions with the working method of design from valve 22, thereby the abrasive mixture in the pipeline 25 is emptied completely.Thereby filter 21 will stop abrasive material to be drawn into the wearing and tearing that jet pump 16 is avoided pump component.
Fig. 2 shows a kind of system that Fig. 1 system is changed to some extent.Wherein many high-pressure bottles 31 of connecting with high-pressure bottle 15.The purpose of doing like this is to make the batch production process among Fig. 1 be transformed into continuous production process.One pipeline 32 is linked second high-pressure bottle 31 from container 15.The outlet of jet pump 16 is linked high-pressure bottle 15 by valve 33,12 also links high-pressure bottle 15 by a choke valve 34 and a valve 35 and enter the mouth.When container 15 chargings, valve 33 is opened and valve 22 cuts out, and forces abrasive mixture to enter high-pressure bottle 31 from high-pressure bottle 15.Valve 33 is closed then, so that force the mixture in the container 31 to flow through pipeline 25 from 12 fluid by jet pump.Meanwhile, make container 15 again from hopper feed with variable pressure source 17 and balloon-like film chamber.The fluid of choke valve 34 and valve 35 of flowing through is used to make container 15 repressurizes, with reach advance the abrasive material thin pulp again after, the pressure identical with container 31.
Figure 3 illustrates the another kind of system that produces variable pressure.In this system, there is a piston 104 to place the bottom of high-pressure bottle 100, pressure is controlled by the pressure that changes in the pipeline 106 and 107.In high-pressure bottle, the abrasive mixture in piston 104 and the container separates by fexible film 102.In this figure, different with Fig. 1, abrasive mixture is within the film chamber, and is the outside in film chamber 19 in Fig. 1.
In the embodiments of figure 3, have only a high-pressure bottle, and in Fig. 4, two high-pressure bottles are arranged, one piston is arranged at the bottom of each high-pressure bottle, is that the abrasive mixture in each high-pressure bottle applies variable pressure by the pressure that is added in pipeline 106 and 107,108 and 109.The method of attachment of having narrated among the method for attachment of the abrasive mixture container of each high-pressure bottle and Fig. 2 among Fig. 4 is identical, repeats no more here.
Another kind has been shown among Fig. 5 to be applied different pressures, makes the form of film that these inclusions discord fluids are directly contacted, be used to apply different pressures simultaneously again in order to the inclusion to high-pressure bottle.Wherein, a reel like film 302 places the inside of pressure vessel 300 walls, inclusion is remained on film chamber the inside and the fluid of exerting pressure is remained on outside the film chamber.Similar film chamber 303 is also arranged in high-pressure bottle 301.Change pressure reduction by pump 315 and valve system 308,309.No longer use jet pump in Fig. 5 and later figure, the mobile of carrier current produced by pump 325 and valve 318-321 and choke valve 335.
In Fig. 5, the abrasive grain source of supply preferably is arranged in the container 317 with the form of dense abrasive slurries, and through piping 321, be transported to the 1st high-pressure bottle 300 by transfer valve 305 again, and described transfer valve 325 is similar with aforementioned valve 20.The pressure control of film 302 is then similar with film 19.After introducing abrasive material, valve 305 cuts out.
The inlet that one carrier current is arranged in the bottom of high-pressure bottle 300, this inlet is controlled by valve 319.Carrier current is provided through a filter and a pump 325 by accumulator 327, is controlled by two parallel pipelines, and each pipeline comprises a choke valve 335 and a valve 318.This pump is provided with a pair of booster, and it can provide the flow of per minute 5 liters for system, about 2.5 hundred million Pascals of pressure, and supercharging stage by stage guarantees between the stage that pulsation is not more than 2%.Flow velocity is by opening the valve 318 in a pipeline or two pipelines and utilizing corresponding choke valve to control.The carrier current that comes out from valve 318 also can flow to second high-pressure bottle 301 by valve 320, and second inlet that exports to second high-pressure bottle 301 at first high-pressure bottle 300 has pipeline 352 to be connected, and controlled by valve 304, the valve 305 of the structure of this valve 304 and high-pressure bottle 300 is similar.The outlet of high-pressure bottle 300 is led to cutting nozzle 323 by tapping equipment 380 and pipeline 322.
Except said apparatus, also have the another one input in the high- pressure bottle 300 and 301 in the device, be used for the fluid high-pressure of supercharging from the accumulator system, a pump 315 is arranged thereon, fluid is transported to accumulator 310.One check-valves 312 that has bypass valve 311 leads to accumulator 314, so that discharging comes the pressure of self-pumping 315, perhaps when needed pumping system is reinjected.When needs have no lingeringly to force abrasive mixture when a high-pressure bottle is sent, pump 325 may not provide the compressibility of the water in the enough timely compensatory pressure vessel volume of fluid.Therefore, the charging fluid in the accumulator 310 is carried by valve 309 (being used for high-pressure bottle 300) and valve 308 (being used for high-pressure bottle 301) by pump 315, and 302,303 protection accumulator systems of film do not allow abrasive grain enter.The purpose of using accumulator is to guarantee have enough fluids to inject high-pressure bottle under pressure, compressibility with the compensation mixture, thereby can be responded fast at nozzle 323 places, the high pressure cutting jet is provided, this jet is tightly followed the action of accumulator system.In addition, when valve 305 is opened, can control the amount of abrasive of introducing from abrasive grain source of supply 317 to the control of the pressure in the pipeline 306.
In Fig. 5, there is a two-way pump 313 with discharge control valve 328 to be arranged on accumulator 314 and leads between the pipeline 306 of high-pressure bottle 300.This pump 313 can be used for providing pressures cycle to high-pressure bottle 300, helping being pumped into abrasive mixture from abrasive containers 317, and forces from the carrier current of remainder when having abrasive grain to be deposited in the high-pressure bottle 300 and flows out.
In use, the high-pressure bottle of charging again 300 of Fig. 5 is equipped with the abrasive material from abrasive containers 317 that sieved in advance.This charging is by realizing at each direction circulating pump 313.Valve 305 and 328 is opened and valve 309 cuts out during charging again.This circulation sucks high-pressure bottle 300 to abrasive material, and discharges remaining water simultaneously, and after this valve 305 and 328 cuts out.
Then valve 309 is opened, and comes the fluid of self-pumping 315 to make film 302 superchargings.When the pressure in the high-pressure bottle 300 when pressure in the high-pressure bottle 301 equates, valve 304 and 319 is opened, and valve 320 cuts out.Meanwhile, come the fluid of self-pumping 325 flow into again the charging high-pressure bottle with abrasive mixture under pressure from film 302, that is be delivered to discharging high-pressure bottle 301 by pipeline 352 and valve 304 from charging high-pressure bottle 300 again.Owing to there is identical pressure to be added on the film of two high-pressure bottles in course of conveying, the pressure of the abrasive mixture that can come out from nozzle discharge can not be affected.
When valve 309,319,320 and 328 cuts out, come self-pumping 315 and acted on fluid pressurized on the film 303 by valve 308 at the abrasive mixture of discharging in the high-pressure bottle 301.
Valve 320 is opened, and flows into high-pressure bottle 301 thereby make from 325 fluid, and forces mixture to flow to nozzle 323 from high-pressure bottle 301 under from 325 carrier current and the acting in conjunction from 315 pressure.Choke valve 335 and 321 allows approximately to come 90070 fluid of self-pumping 325 by 321, and in the downstream and mixture junction of pipeline 322.
Pressure in the system can make high-pressure bottle 300 step-downs of charging more earlier and be discharged.At this moment, valve 308,319 and 320 cuts out and valve 309 is opened.Pressure releases or releases pump 315 itself from valve 311.Then conversely, with same method release pressure from discharging high-pressure bottle 301 with valve 308 and 309.If use pump 315, it may need to refill fluid through valve 312 at another time of beginning supercharging circulation time.Use in the operation, at all these Yi Bian the right hand of Fig. 5 device all is protected from entering of abrasive material by film.
If without container 317, also can allow abrasive slurries container 331 high-pressure bottle 300 of directly packing into, and fixing on the throne by screw.This container has a kind of special outlet to go out high-pressure bottle 301 to the abrasive material thin pulp by pipeline 352 together with the water from valve 319.About described in Fig. 5 comprise parallel pipeline and valve 318 volume control devices also can be arranged in the bypass channel 337, as shown in Figure 6.Two parallel pipelines among Fig. 6 comprise a valve and current limiter 335 separately, are arranged in the outlet and the bypass duct 337 between the pipeline 322 of valve 320.When adopting this structure, there is a choke valve 336 to be arranged between tapping equipment 380 and the pipeline 322 in addition, replaces by valve 334 about the choke valve shown in Fig. 5 321.Though because they get clogged than being easier to, it is nearer that choke valve leaves abrasive grain, and still, choke valve 335 and valve 318 are positioned at the part that carrier current is provided to abrasive mixture, therefore not conference is subjected to the pollution of abrasive grain, so this arrangement of choke valve is favourable to production.When abrasive flows stopped, choke valve 336 can prevent abrasive material plug nozzle pipeline.
The coaxial reel like film of above-mentioned and high-pressure bottle can be replaced by the tubular film 338 of closure, and the latter is parallel to from the space of the axis of high-pressure bottle, as shown in Figure 7.Enclosed an inlet tube 339 in the tubular film, the end of this inlet tube 339 can be that porous can be an atresia also, and it can provide support and additional seal for tubular film when adding buffer brake.This tubular film is comparatively similar to the balloon-like film shown in Fig. 1 and Fig. 2.
Except the direct connection between high- pressure bottle 300 and 301, between each P-V, can also be provided with and comprise the pump 350 that is connected in series and the connecting pipe of valve 351, as shown in Figure 8 away from the film side of abrasive mixture.Pump 350 can be used for circularly-supercharged fluid between two high-pressure bottles, to help abrasive mixture by direct-connected pipeline 352.Here, in the structure of Fig. 8, high-pressure bottle 300 is not arranged on the carrier current pipeline that passes through valve 319 that has among other figure connects the conveying of helping between high- pressure bottle 301 and 302.
Fig. 9 shows another kind of abrasive material and is mixed in apparatus structure in the liquid, and this structure is suitable for use in nozzle 323 places not to be needed quick startup, stop the occasion to change with pressure.Conveying from filling device again to the abrasive material the high-pressure bottle 300 realizes by circulating pressure the pipeline 355, and the outside of the tubular film in this pipeline 355 and the high-pressure bottle 354 is connected.The inside of film 353 is by the inside of the film 338 in valve 357 and the high-pressure bottle 300 link to each other (338 to 353 firmly).After high-pressure bottle 300 had filled into abrasive material, pressure was added in the high-pressure bottle 354 through pipeline 355, and fluid is entered film 338, and its amount equals the compression volume of the fluid of high-pressure bottle 300 under condition of work at least.After this measure was finished, valve 357 cut out, and high-pressure bottle 300 is pressurized by opening the valve 358 that leads to accumulator 346.Then, valve 304 and 319 is opened, as mentioned above abrasive material is transported to high-pressure bottle 301 from high-pressure bottle 300.When decompression, shut off valve 358,319 and 304 before valve 357 is opened.In this embodiment, film 338 is used for making abrasive material and pressurized source 355 to isolate, but is not to isolate with accumulator 346.
