Description
A Gradient-Type Horizontal Premixing Ultra-High-Pressure Abrasive-Jet Generator Based on Self-Adaptive Fluidization Mechanism
Technical Field
The invention relates to the technical field of design for abrasive-water-jet machines, in particular to a gradient-type horizontal premixing ultra-high-pressure abrasive-jet generator based on self-adaptive fluidization mechanism.
Background
Water jet refers to the high-speed water beam with different shapes outflowing from a nozzle, and the flow velocity of the jet depends on the pressure drop at the nozzle outlet. The water-jet technology is the simplest method for energy transformation and application. Usually, a power-driven pump draws in certain amount of water and discharges it to a high-pressure pipeline, then makes the water arrive at the nozzle with proper energy. The bore diameter of the nozzle is much smaller than the diameter of the high-pressure pipeline, therefore the water arriving at the nozzle must be accelerated so as to flow out. Thus the accelerated and condensed water flowing out of the nozzle transforms into a water jet. Abrasive jet refers to the jet formed by abrasive moving at a high speed after being accelerated by certain external force. Conventional abrasive-water-jet equipment uses water as medium, and provides the water with huge energy through a high-pressure generator, then injects the abrasive into the high-pressure water through a feeding device and makes the mixture shoot up from the nozzle at a high speed in a specific fluid movement, forming an abrasive-water jet containing highly intensive energy.
According to domestic and foreign researches, the fluidization effect of abrasive and water in an abrasive tank under vertical condition turns out to be better than that under vertical condition due to the weight of the abrasive. Currently, the abrasive tank of the premixing abrasive-jet equipment has relatively low capacity and is suitable for vertical installment, and has an advantage of portability and is usually called the portable water jet. Limited by the size of the abrasive tank, the premixing abrasive-jet equipment cannot operate continuously. Nevertheless, with the development of industrial technology, the operation time of the premixing abrasive equipment has been extended and the capacity of the abrasive tank has been enlarged, and the “high and thin” feature of the abrasive tank has gradually changed to tlae^01 “short and thick” feature, which doesn't allow for the vertical installment of the abrasive tank and invalidates the advantage of the portable water jet. Especially, when the production of the abrasive tank that can bear ultra-high pressure proves to be difficult due to relevant material deficiency, some domestic research institutes usually use the long tank with small diameter to achieve high-pressure tolerance. As the research on material of the abrasive tank by the domestic research institutes goes deeper, the material for ultra-high-pressure abrasive tank of commercial purpose will be excogitated later. Nevertheless, the premixing ultra-high-pressure abrasive-jet generator still has a series of problems at present. The existing premixing ultra-high-pressure abrasive-jet generator can neither avoid the problem brought by the difficult production of high-pressure vessel with large diameter and huge capacity due to relevant material deficiency, nor solve the instability problem of the vertical large-capacity ultra-high-pressure abrasive tank due to axially overhigh center of gravity; some premixing ultra-high-pressure abrasive-jet generators can neither achieve the transverse delivery of the abrasive in horizontal low-pressure sand tanks, nor avoid the problem of stacking abrasive at the downside of horizontal low-pressure sand tanks due to gravity; some premixing ultra-high-pressure abrasive-jet generators can neither achieve dual functions of spirally accurate delivery and throttled slurry output, nor accurately control the concentration of the slurry; though some premixing ultra-high-pressure abrasive-jet generators can achieve the function of the slurry delivery, they can neither thoroughly mix the slurry in the horizontal self-adaptive slurry fluidization tanks, nor avoid the instability problem of the slurry concentration caused by the mixing of the slurry in the booster valves, thus leading to a large fluctuation range of the slurry output concentration. Therefore, it is of necessity to provide a gradient-type horizontal premixing ultra-high-pressure abrasive-jet generator based on self-adaptive fluidization mechanism with a simple structure that is safe, high-efficient and easy to operate.
Summary of the Invention
The invention is to overcome the defects of the prior art and provide a gradient-type horizontal premixing ultra-high-pressure abrasive-jet generator based on self-adaptive fluidization mechanism with a simple structure that is safe, high-efficient and easy to operate.
In order to solve the technical problems, the technical scheme of the invention is given as 1°1<: follows: a gradient-type horizontal premixing ultra-high-pressure abrasive-jet generator based on self-adaptive fluidization mechanism, comprising a fixed-mobile dual-mode cart, a horizontal low-pressure sand tank, a horizontal self-adaptive slurry fluidization tank and a horizontal ultra-high-pressure tank, and the axes of the horizontal low-pressure sand tank, the horizontal self-adaptive slurry fluidization tank and the horizontal ultra-high-pressure tank are all normal to the midperpendicular of the fixed-mobile dual-mode cart; an end seat is mounted at the left end of the horizontal low-pressure sand tank, and a water injection pipeline is mounted at the upper end of the end seat, and a distribution pipeline is mounted at the middle of the water injection pipeline; a normally-opened two-position valve is mounted at the right end of the end seat, a horizontal runner and a downslope runner are provided in the normally-opened two-position valve, and the angle between the axes of the horizontal runner and the downslope runner ranges from 45° to 60°, and the upper generatrix of the normally-opened two-position valve coincides with that of the end seat; a special valve is mounted between the horizontal low-pressure sand tank and the horizontal self-adaptive slurry fluidization tank, and a horizontal stepped throttling runner is provided in the special valve; a vertically spiral conveyer is mounted in the special valve, and the axis of the horizontal stepped throttling runner is normal to that of the vertically spiral conveyer, and the vertically spiral conveyer is also mounted at the middle of the horizontal stepped throttling runner; a swirler is mounted at the right end of the special valve, and a horizontal slurry delivery pipeline is mounted in the swirler through a bearing, and a rotary impeller is mounted at the right end of the horizontal slurry delivery pipeline, and the right end of the horizontal slurry delivery pipeline and the rotary impeller are both placed in the horizontal self-adaptive slurry fluidization tank; an annular groove is provided in the swirler, and a hydrodynamic impeller is mounted in the annular groove, and the hydrodynamic impeller is fixed on the horizontal slurry delivery pipeline; a one-way valve for water feeding is mounted at the upper side of the annular groove, and the upper end of the one-way valve for water feeding is connected with the distribution pipeline, and a booster valve seat is mounted at the right end of the horizontal self-adaptive slurry fluidization tank, and the booster valve seat is connected with the horizontal ultra-high-pressure tank through a high-pressure sand pipe. A sand feeding pipe is mounted at the lower end of the horizontal low-pressure sand tank, and a humidifying sand-water pipe is mounted at one side of the sand feeding pipe; a spiraV101*· delivery blade is mounted on the vertically spiral conveyer, and a stepping motor is mounted at the upper end of the vertically spiral conveyer; a seal assembly is mounted at the left end of the horizontal slurry delivery pipeline and at the right end of the horizontal stepped throttling runner, and a one-way valve for water discharging is mounted at the lower side of the annular groove and the one-way valve for water discharging is connected with the water injection pipeline through a high-pressure hose. A two-layer supporting frame is mounted at the upper end of the fixed-mobile dual-mode cart, and a C-shape mounting ring (A) and a C-shape mounting ring (B) are mounted at the upper side of the two-layer supporting frame; an H-shape mounting frame is mounted at the middle of the two-layer supporting frame, and the horizontal low-pressure sand tank is mounted on the two-layer supporting frame through the C-shape mounting ring (A), and the horizontal self-adaptive slurry fluidization tank is mounted on the two-layer supporting frame through the C-shape mounting ring (B), and the horizontal ultra-high-pressure tank is mounted on the two-layer supporting frame through the H-shape mounting frame. A main water delivery pipeline is mounted at the upper end of the booster valve seat, and the main water delivery pipeline is connected with the water injection pipeline through a diverter valve, and a sprayer is connected to an ultra-high-pressure valve seat at the left end of the horizontal ultra-high-pressure tank through a high-pressure sand pipe.
Under practical application circumstance, first of all, the operator should fix the target on the workbench of three-dimensional coordinatograph, and fix the sprayer on the cutting seat of the workbench of three-dimensional coordinatograph, then inject dry sand into the horizontal low-pressure sand tank through the sand feeding pipe. Meanwhile, the operator should connect the sand feeding pipe to the outlet of the water pump. Then the operator should turn on the water pump, and wait until the dry sand mixes with the water and the mixture fills the whole horizontal low-pressure sand tank, then turn off the water pump to stop injecting dry sand into the horizontal low-pressure sand tank. Then the operator should place the target at a proper distance to the bottom of the sprayer, and lock the relative distance between the sprayer and the target, and then confirm the moving direction of the sprayer.
Next, the operator should move the fixed-mobile dual-mode cart to the non-operation area of the laboratory, and adjust the position of the supporting legs on the fixed-mobile dual-mode cart until the wheels of the fixed-mobile dual-mode cart leave the ground at a certain distance^101*· then connect the booster valve seat to the ultra-high-pressure pump station and switch on the ultra-high-pressure pump station, then low-pressure water will flow into the end seat through the water injection pipeline and be divided into two streams by the horizontal runner and the downslope runner in the normally-opened two-position valve and flow into the horizontal low-pressure sand tank. The low-pressure water mixes with the sand in the horizontal low-pressure sand tank, and the slurry will flow into the horizontal stepped throttling runner in the special valve. Then the operator should turn on the stepping motor in accordance with the output concentration of the jet to make the vertically spiral conveyer rotate at a proper speed, and the slurry will flow into the horizontal self-adaptive slurry fluidization tank through the horizontal slurry delivery pipeline.
Meanwhile, one stream from the water injection pipeline will flow into the annular groove of the swirler through the distribution pipeline and the one-way valve for water feeding, and the hydrodynamic impeller will begin to rotate and drive the impeller at the end of the horizontal slurry delivery pipeline, and sufficiently mix the slurry in the horizontal self-adaptive slurry fluidization tank until the slurry turns fluidized. Then the water in the annular groove will flow into the water tank through the pipeline at the end of the one-way valve for water discharging and the fluidized slurry will mix with the ultra-high-pressure water in the booster valve seat and the mixture will flow into the horizontal ultra-high-pressure tank through the high-pressure sand pipe, and the ultra-high-pressure slurry will spray out from the sprayer after flowing though the ultra-high-pressure valve seat and the high-pressure sand pipe.
Finally, the operator should turn on the workbench of three-dimensional coordinatograph to make the sprayer start moving. After the completion of the target cutting, the operator should completely discharge the slurry in the horizontal low-pressure sand tank, the horizontal self-adaptive slurry fluidization tank and the horizontal ultra-high-pressure tank, and reset the cutting seat of the workbench of three-dimensional coordinatograph, then turn off the ultra-high-pressure pump station, thus completing the cutting work by the ultra-high-pressure abrasive jet.
Compared with the prior art, the beneficial effects of the invention are as follows: the horizontal arrangement for high-pressure tanks adopted by the invention can solve not only the problem brought by the difficult production of high-pressure vessel with large diameter and huge capacity due to relevant material deficiency, but also the instability problem of the vertical101C large-capacity ultra-high-pressure abrasive tank due to axially overhigh center of gravity; the horizontal runner and the downslope runner in the normally-opened two-position valve can help achieve horizontal delivery of slurry in the horizontal low-pressure sand tank, and avoid the problem of stacking abrasive at the downside of the horizontal low-pressure sand tank due to gravity; the special valve and the vertically spiral conveyer can help achieve the dual functions of spirally accurate delivery and throttled slurry output, as well as accurate control of the slurry concentration; the horizontal slurry delivery pipeline and the rotary impeller can help achieve the delivery of the slurry, and sufficiently mix the slurry in the horizontal self-adaptive slurry fluidization tank, thus avoids the instability problem of the slurry concentration caused by the mixing of the slurry in the booster valve, and further reduces the fluctuation range of the slurry output concentration; the swirler and hydrodynamic impeller use water as the power to drive the impeller on the horizontal slurry delivery pipeline, and adjust the revolving speed of the rotary impeller in real time in accordance with the flow rate within the water injection pipeline,. Moreover, the invention has a simple structure and is practical, economical and easy to operate.
