Description
Ejector Mechanism-Based Ultrahigh Pressure Abrasive Jet Generator HUToTaar Field of the Invention The invention relates to the technical field of abrasive water jet machinery design, in particular to an ejector mechanism-based ultrahigh pressure abrasive jet generator.
Background of the Invention Water jets are high-speed water jets of different shapes from nozzles.
The flow rate of jets depends on pressure drop in front of and behind outlet sections of the nozzles.
Water jets are the simplest form of energy transformation and application.
A power-driven pump generally pumps a certain amount of water to a high pressure line by completing a suction and discharge process for the water, so that the water can reach a nozzle with a certain amount of energy.
The aperture of the nozzle is much smaller than the diameter of the high pressure line; as a result, the water reaching the nozzle must be accelerated to flow out of the nozzle hole.
In such a way, the water accelerated and condensed through the nozzle hole forms a jet.
An abrasive jet refers to a jet formed by abrasive moving at high speed after the abrasive is accelerated under the action of an external force.
A conventional abrasive water jet machine uses water as a medium and obtains huge energy through a high pressure generator.
Then an abrasive is directly injected into high pressure water through a feeding device to eject out of a nozzle at a high speed in a specific fluid motion mode, forming an abrasive water jet with concentrated energy at high speed.
However, the existing ejector mechanism-based ultrahigh pressure abrasive jet generator cannot compensate the cutting of materials with different longitudinal sizes, so as not to form a negative pressure vacuum state in the ejection cavity for entraining dry sand, supplement the abrasive concentration of the original abrasive jet, and improve the striking force of the abrasive jet.
Moreover, it is difficult to avoid the situation that materials with local longitudinal sizes cannot be cut through due to insufficient jet energy.
As a result, the function of cutting materials with different longitudinal sizes cannot be realized.
In some cases, some ejector mechanism-based ultrahigh pressure abrasive jet generators cannot accelerate the abrasive jet output by the pre-mixed abrasive jet generator to form a jet at the tapered port, or entrain dry sand into the negative pressure vacuum area in the ejector cavity, or realize the acceleration function on the injected abrasive mixture.
In another case, some ejector mechanism-based ultrahigh pressure abrasive jet generatorscannot increase the secondary mixing effect of the dry sand injected and entrained and the abrasive |j101447 mixture output by the main output pipe, increase the turbulence degree of the mixture in the straight pipe turbulence cavity, even the turbulence effect; thus, they cannot improve the uniformity of the concentration of the mixture and meet actual demands. Therefore, it is necessary to provide an ejector mechanism-based ultrahigh pressure abrasive jet generator that is structurally simple, quick and convenient to operate, safe and efficient. Summary of the Invention To overcome the disadvantages of the prior art and solve the technical problem, the invention provides an ejector mechanism-based ultrahigh pressure abrasive jet generator.
In order to achieve the purpose, the invention is realized by the following technical solution: an ejector mechanism-based ultrahigh pressure abrasive jet generator, comprising an air-filled dry sand tank, a pre-mixed abrasive generator and a numerical control machine tool, and further comprising a secondary sand mixing ejector pipe, wherein the secondary sand mixing ejector pipe comprises an ejector pipe and a main output pipe; the ejector pipe is installed at the right end of the main output pipe and internally provided with an ejector cavity; the ejector cavity is also arranged at the left end of the ejector pipe; a tapered port is arranged at the end of the main output pipe and also arranged in the ejector cavity; a dry sand suction channel is symmetrically arranged around the ejector cavity and a bell mouth-shaped throttling cavity is arranged at the right end thereof; a wide-mouth divergence cavity is arranged at the right end of the bell mouth-shaped throttling cavity; a straight pipe turbulence cavity is arranged at the right end of the wide-mouth divergence cavity and internally provided with a turbulence column; a port throttling accelerating cavity is arranged at the right end of the straight pipe turbulence cavity, and the port throttling accelerating cavity is also arranged at the right end of the ejector pipe.
The diameter of the cross section at the right end of the tapered port is smaller than that of the cross section at the right end of the bell mouth-shaped throttling cavity; the diameter of the cross section at the right end of the port throttling accelerating cavity is smaller than that of the cross section at the right end of the tapered port; a nozzle is arranged at the right end of the secondary sand mixing ejector pipe through a threaded pressing cap; three turbulence columns are arranged and symmetrically distributed in the shape of a triangle, and surrounding arc-shaped bulges are arranged in the middle part of the turbulence columns.
A multi-channel output valve body is mounted at the lower end of the air supplementing typ4 1401447 dry sand tank and provided with a steel sand pipe, and the right end of the steel sand pipe is arranged at the input end of the dry sand suction channel through a high pressure joint.
The pre-mixed abrasive generator comprises a mixing cavity seat and an ultrahigh pressure abrasive tank, wherein a one-way output valve is arranged on the left side of the mixing cavity seat and the left end thereof is connected with the input end of the main output pipe through a high pressure rubber hose; a one-way input valve is arranged at the right side of the mixing cavity seat and the right end thereof is connected with a high pressure pump station through a high pressure rubber hose; the ultrahigh pressure abrasive tank is arranged at the upper end of the mixing cavity seat, and a portable cart is arranged at the lower end thereof.
The numerical control machine tool comprises a two-degree-of-freedom cantilever type actuator arm and a workpiece clamping table, wherein the two-degree-of-freedom cantilever type actuator arm is arranged at the upper end of the numerical control machine tool; a clamping seat is arranged on the two-degree-of-freedom cantilever type actuator arm; a secondary sand mixing ejector pipe is installed on the clamping seat, and the workpiece clamping table is arranged directly below the clamping seat.
When the numerical control machine tool is used on site, firstly, an operator fixes the material workpieces with different longitudinal sizes on a workpiece clamping table at the upper end of a numerical control machine tool, installs and fixes a secondary sand mixing ejector pipe on the clamping seat of a two-degree-of-freedom cantilever type actuator arm, adjusts a numerical control panel on the numerical control machine tool to enable the two-degree-of-freedom cantilever type actuator arm to be at a proper position, adjusts the position of a nozzle at the bottom of the secondary sand mixing ejector pipe to maintain the material workpieces with different longitudinal sizes and the bottom of the nozzle in a target distance range suitable for cutting, then sets the starting positions of the material workpieces with different longitudinal sizes through a numerical control panel on a numerical control machine tool, and sequentially transmits the walking parameters to a travelling actuator of a two-degree-of-freedom cantilever type actuator arm through a controller according to a feeding path on the numerical control panel.
Secondly, the operator moves the air supplementing type dry sand tank and the pre-mixed abrasive generator to the non-working area, fixes the air supplementing type dry sand tank and the pre-mixed abrasive generator respectively, loads the dry sand into the air supplementing type drysand tank and the ultrahigh pressure abrasive tank respectively, installs a water pipe connection end |j101447 on the water tank of the high pressure pump station, and connects the output end of the high pressure pump with the one-way input valve at the right end of the mixing cavity seat through the high pressure rubber hose, then connects the one-way output valve at the left end of the mixing cavity seat with the main output pipe at the end of the secondary sand mixing ejector pipe through the high pressure rubber hose, and starts the high pressure pump station to enable high pressure water to enter the ultrahigh pressure abrasive tank through the mixing cavity seat and mix with the abrasive in the mixing cavity seat.
The abrasive mixture enters the main output pipe through the high pressure rubber hose.
Thirdly, the primary abrasive mixture enters the main output pipe and is ejected out of the tapered port, and then forms a negative pressure vacuum area at the edge part in the ejector cavity.
Dry sand in the dry sand suction channel is entrained into the ejector cavity at negative pressure and is mixed with the primary abrasive mixture to produce new abrasive mixture that is accelerated into the wide-mouth divergence cavity through the bell mouth-shaped throttling cavity where it divergently flows into the straight pipe turbulence cavity.
Now, the dry sand entrained at the negative pressure is not completely mixed with the primary abrasive mixture; moreover, due to the surrounding arc-shaped bulges in the middle of the turbulence column, the dry sand entrained at the negative pressure is not broken up with the original fluidization of the primary abrasive mixture to form turbulence, which intensifies the previous incomplete mixing and results in the more concentrated abrasive mixture.
The finally mixed abrasive mixture is ejected out of the nozzle under the acceleration effect of the port throttling accelerating cavity, and the materials and workpieces with different longitudinal sizes are machined.
Finally, the operator sequentially closes the numerical control panel on the numerical control machine tool for controlling the movement of the two-degree-of-freedom cantilever-type actuator arm and the abrasive valve on the mixing cavity seat.
After only clean water is output from the nozzle, the operator reduces the output flow rate of the high pressure pump station until the high pressure pump station is closed.
Then, the operator reasonably cleans the abrasive in the ultrahigh pressure abrasive tank according to the next operation time and maintains the device regularly for the next cutting work.
Compared with the prior art, the invention has the following beneficial effects.
The invention can compensate the cutting of materials with different longitudinal sizes, and form a negativepressure vacuum state in the ejection cavity for entraining dry sand, so as to supplement the 3401447 abrasive concentration of the original abrasive jet, increase the striking force of the abrasive jet, and fully avoid the situation that materials with local longitudinal sizes cannot be cut through due to insufficient jet energy.
Thus, the invention can effectively solve the problem of uneven 5 concentration of secondary abrasive mixture caused by injecting dry sand.
The arrangement of the main output pipe, the tapered port, the ejector pipe and the ejector cavity allows the abrasive jet output by the pre-mixed abrasive jet generator to be accelerated into a jet at the tapered port and form a vacuum area in the ejector cavity.
The arrangement of the dry sand suction channel, the bell mouth-shaped throttling cavity and the wide-mouth divergence cavity allows entraining dry sand into the negative pressure vacuum area in the ejector cavity, which realizes the function of accelerating the ejected abrasive mixture.
The accelerated abrasive mixture is divergently output in the wide-mouth divergence cavity for twice, aiming at making subsequent abrasive mixture into turbulence and increasing the uniformity of the mixed concentration.
The arrangement of the straight pipe turbulence cavity, the turbulence column and the port throttling accelerating cavity can increase the secondary mixing effect of entrained dry sand and abrasive mixture output by the main output pipe, and improve the turbulence degree of the mixture in the straight pipe turbulence cavity, the turbulence effect and the concentration uniformity of the mixture.
Thus, the invention has simple structure, and is convenient to operate, economical and practical.
