The present application can solve the problem that the prior art has not taken into account, that is, due to the different sizes of solid particles in the flue gas, when impurities of different sizes are intercepted by the upper baffle and the lower baffle, blockage may occur.

Description

Technical Field

[0001] The present invention relates to the technical field related to plasma cutting, and in particular to a heavy-duty gantry-type plasma cutting device for producing a waterjet cutting robot. Background Art

[0002] When producing waterjet cutting robots, plasma cutting is required to cut the workpiece plates. Plasma arc cutting is to pass a mixed gas through a high-frequency arc. The gas can be air or a mixture of hydrogen, argon and nitrogen. The high-frequency arc "decomposes" or ionizes some gases into basic atomic particles, thereby producing "plasma". Then, the arc jumps to the stainless steel workpiece, and the high-pressure gas blows the plasma out of the cutting torch burner with an outlet speed of 800 to 1000 meters per second (about 3 Mach). In this way, the high energy released when the various gases in the plasma return to normal state produces a high temperature of 2700°C. This temperature is almost twice the melting point of stainless steel. As a result, the stainless steel melts quickly, and the molten metal is blown away by the ejected high-pressure airflow. Therefore, smoke exhaust and slag removal equipment is required.

[0003] In the existing technology for flue gas filtration, such as the Chinese patent with the announcement number CNU, a plasma cutting flue gas purification system is disclosed, including a flue gas extraction component and a flue gas purification component connected by a first pipe, the flue gas extraction component includes air ducts located on both sides of the plasma cutting platform, a sealing cloth belt and a negative pressure air suction port used in conjunction with the air duct, the negative pressure air suction port is used in conjunction with the sealing cloth belt, the negative pressure air suction port is arranged on the mobile frame of the plasma cutting machine and moves with the mobile frame to introduce the smoke gas generated during cutting into the air duct, the air outlet end of the air duct is connected to the air inlet end of the first pipe, the flue gas purification component includes a smoke filter and a smoke purifier, the smoke filter is provided with an air inlet and an air outlet, the air inlet is connected to the air outlet end of the first pipe, and the air outlet is connected to the smoke purifier through the second pipe.

[0004] In the above technology, impurities such as dust, welding slag, etc. in the flue gas are effectively blocked mainly by the upper baffle and the lower baffle which are staggered in the upper and lower order in the smoke filter, and the settled impurities are collected and processed in a centralized manner through the slag collecting hopper. However, the blockage situation is not taken into consideration. Since the solid particles in the flue gas are of different sizes, when the impurities of different sizes are intercepted by the upper and lower baffles, blockage may occur. Since it is not cleaned in time, the blockage becomes more and more serious with the passage of time, and eventually causes the filtration and interception to fail.

[0005] Based on this, there is still room for improvement on the existing flue gas filtration technology. Summary of the invention

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-Figure 9 This application is described in further detail.

[0036] The embodiment of the present application discloses a heavy-duty gantry plasma cutting device for the production of water jet cutting robots. The present application performs multiple filtration and purification on the smoke generated by the cutting, performs separate stripping filtration and interception on large and small particle impurities, and provides targeted solutions to possible blockages. At the same time, the passing smoke is purified by regular dipping, thereby improving the cleanliness of the smoke exhaust.

[0037] Reference Figure 1-Figure 3As shown, a heavy-duty gantry plasma cutting device for waterjet robot production disclosed in this embodiment includes a base guide rail 1, a crossbeam guide rail 2, a drive module 3, a plasma cutting module 4, a shell 5, an inlet 6, a filter group 7, a filter purification module 8, and a wet filter module 9. The base guide rail 1 is a fixed foundation, the crossbeam guide rail 2 is slidably arranged between the base guide rails 1 along the front and rear directions, the drive module 3 is slidably arranged at the upper end of the crossbeam guide rail 2 along the left and right directions, the plasma cutting module 4 is installed at the left end of the drive module 3, the shell 5 is installed at the right end of the drive module 3 through a bracket, and the inlet Port 6, a filter group 7 is rotated inside the entrance port 6, and the filter group 7 regularly discharges the intercepted large particles of impurities. The filter purification module 8 is installed inside the shell 5, and the filter purification module 8 performs multiple filtering and purification on the incoming flue gas. The wet filter module 9 is installed at the upper end of the shell 5, and the filter group 7 is connected to the wet filter module 9 through a conveyor belt. When the filter group 7 rotates intermittently, the wet filter module 9 works synchronously to inject the purifier into the wet filter module 9 to wet-clean the passing flue gas. The air outlet is opened on the inner rear side of the shell 5, and the filtered and purified flue gas is discharged from the air outlet.

[0038] In the actual operation process, the workpiece plate of the water jet cutting robot is placed in the cutting area and positioned, and the base guide rail 1, the beam guide rail 2, and the driving module 3 cooperate to drive the plasma cutting module 4 to move in the X and Y directions, and the plasma cutting module 4 is lifted and lowered in the Z direction, so as to perform plasma cutting on the plate. The smoke generated in the cutting process enters the inlet 6, and then passes through the filter group 7, the filter purification module 8, and the wet filter module 9 in sequence and is purified and discharged. The large particles of impurities in the smoke are intercepted and regularly discharged by the filter group 7, and the small particles of impurities are intercepted and retained by the filter purification module 8. The specific organic waste gas (such as organic solvent volatiles) in the smoke is adsorbed by activated carbon, and then the dust in the smoke is wet-attached and the smoke is purified by the wet filter module 9, so as to achieve the purpose of multiple filtration and purification. The present application performs stripping retention of different media in the smoke to avoid single-layer blockage and incomplete purification.

[0039] Reference Figure 4 As shown, the smoke generated by cutting is sucked into the inlet 6. The specific structure is that the inlet 6 includes an intermediate tube 61, a smoke inlet 62, a focusing frame 63, and a return pipe 64. The intermediate tube 61 is connected to the shell 5 through a connecting pipe. A pump body is installed in the middle of the connecting pipe. The smoke inlet 62 is connected and installed at the lower left of the intermediate tube 61. A focusing frame 63 with a filtering function is installed directly below the intermediate tube 61 with a circular structure. A return pipe 64 is connected between the focusing frame 63 and the connecting pipe.

[0040] Reference Figure 4As shown, the centralized frame 63 is composed of a frame body, a pull-out frame and a filter assembly. The inlet of the frame body is connected to the intermediate pipe 61, and the outlet of the frame body is connected to the return pipe 64. A pull-out frame is pulled out inside the frame body, and a filter assembly is arranged on the pull-out frame. The filter assembly in the initial position is attached to the outlet position of the frame body.

[0041] During the actual operation, the smoke is sucked into the smoke inlet 62 by the pump body, and then enters the shell 5 after passing through the intermediate pipe 61 and the connecting pipe.

[0042] Reference Figure 4 , Figure 5 As shown, in order to intercept and regularly discharge large particles of impurities, the present application provides a rotatable filter group 7 in the intermediate tube 61. The specific structure is that the filter group 7 includes a rotating roller 71, an input port 72, a linkage plate 73, a filter element 74, and an opening and closing member 75. The front and rear ends of the rotating roller 71 are provided with an electric turntable, which is installed at the axial position of the side wall of the intermediate tube 61. The interior of the rotating roller 71 is provided with an input port 72 with a blocking function in a clockwise direction. The linkage plates 73 are sequentially installed in the clockwise direction of the rotating roller 71. A conveying cavity is provided in the linkage plate 73, and the conveying cavity is connected to the input port 72. The filter element 74 is slidably arranged on one side of the linkage plate 73 along the width direction of the linkage plate 73, and the opening and closing member 75 is slidably arranged on the other side of the linkage plate 73 along the height direction of the linkage plate 73.

[0043] In actual operation, the electric turntable drives the rotating roller 71 to rotate intermittently (the angle of a single rotation is one hundred and eighty degrees). After the smoke enters the intermediate tube 61, the smoke is filtered and intercepted by the filter element 74 in the upper linkage plate 73. At the same time, the lower linkage plate 73, the filter element 74, and the opening and closing element 75 form a closed space (conveying space). Part of the smoke enters the conveying space through the lower input port 72. With the help of the smoke in the smoke, the impurities intercepted in the closed space are discharged downward into the concentration frame 63, and thus are retained in the concentration frame 63 (the pull-out frame can be opened later to centrally clean large particles of impurities). The filtered smoke is converged into the connecting pipe through the reflux pipe 64 and continues to be centrally conveyed backward.

[0044] Reference Figure 5As shown, in order to prevent the smoke entering the upper linkage plate 73 from not being filtered by the filter element 74 but being transported from the input port 72 arranged above (directly output from the input port 72 without being filtered), the present application provides a one-way valve 76 inside the input port 72, and the one-way valve 76 includes an intercepting plate 761, a blocking block 762 and a built-in spring 763. The number of intercepting plates 761 is two, and the intercepting plates 761 are connected to the inner wall of the input port 72 through a pin shaft. One side of the intercepting plate 761 close to the center position of the intermediate tube 61 is attached to the blocking block 762, and the blocking block 762 is installed on the inner wall of the input port 72. The other side of the intercepting plate 761 is connected to the inner wall of the input port 72 with a built-in spring 763, and the built-in spring 763 plays a role in connection reset.

[0045] During actual operation, the one-way valve 76 located in the upper input port 72 works as follows: when smoke enters the input port 72, it impacts the interception plate 761 to rotate downward, but due to the resistance of the blocking block 762, the two interception plates 761 can only be in the same horizontal plane and will not continue to rotate downward. At this time, the two interception plates 761 in the same horizontal plane form a closed state for the input port 72, ensuring that smoke can only pass through the filter element 74 above; the one-way valve 76 located in the lower input port 72 works as follows: when smoke enters the input port 72, it impacts the interception plate 761 to rotate downward, thereby opening the input port 72 and ensuring the normal input of local smoke.

[0046] Reference Figure 5 As shown, the filter element 74 includes a sliding member 741, a filter screen 742, and a puncture-type brush member 743. A sliding groove is evenly opened on one side surface of the linkage plate 73. A sliding member 741 is slidably arranged in the sliding groove. A filter screen 742 is installed inside the sliding member 741. A rotating shaft is symmetrically arranged at one end of the sliding member 741 away from the clutch 75, and a torque spring is connected between the rotating shaft and the sliding member 741. A puncture-type brush member 743 is installed on the rotating shaft. The setting of the torque spring ensures that the initial angle of the puncture-type brush member 743 is arranged at an inclined angle. The setting of the puncture-type brush member 743 makes it possible for the linkage plate 73 to rotate to the bottom. The impact force of the flue gas causes the piercing brush member 743 arranged at an inclined angle to adjust its angle so as to close the left opening position of the sliding member 741 directly below. When closing, on the one hand, the piercing brush member 743 pushes out the particles attached to the surface of the filter screen 742, and on the other hand, the sliding member 741 with the left opening closed moves under the impact of the flue gas so that the passing grooves 7411 opened above and below the sliding member 741 are no longer blocked by the side walls of the sliding groove, and the passing grooves 7411 are exposed to the interior of the linkage plate 73. At this time, the flue gas output through the input port 72 can blow and clean both sides of the filter screen 742 so that impurities are transported to the concentration frame 63.

[0047] Reference Figure 5 , Fig. 9 As shown, the upper and lower ends of the sliding member 741 are symmetrically provided with passing grooves 7411, the passing grooves 7411 at the initial position are blocked by the side walls of the sliding groove, the puncture-type brush members 743 are initially arranged at an inclined angle, and the spacing between the upper and lower arranged puncture-type brush members 743 gradually increases from the outside to the inside, and the angled arrangement ensures that the puncture-type brush members 743 can be expanded or merged in time under the impact of smoke, ensuring that the opening position of the sliding member 741 is fully opened or fully closed; the opening and closing member 75 is a plate structure, and the opening and closing member 75 is evenly provided with alignment grooves from top to bottom, and the other side of the linkage plate 73 is evenly provided with ventilation grooves, and the alignment grooves at the initial position correspond to the positions between the ventilation grooves.

[0048] In the filtering and intercepting operation of large particles of impurities in the flue gas, when the linkage plate 73 is in the upper position, under the action of gravity of the opening and closing member 75, the alignment groove in the opening and closing member 75 is aligned with the ventilation groove (ventilation). At this time, the flue gas passes through the ventilation position and is filtered and intercepted by the filter screen 742 above. When the linkage plate 73 is in the lower position, under the action of gravity of the opening and closing member 75, the alignment groove in the opening and closing member 75 and the ventilation groove are staggered (closed). At the same time, under the impact of the flue gas, the sliding member 741 is pushed to the right so that the passing groove 7411 on the sliding member 741 is exposed (enters the conveying space). Since the linkage plate 73 and the opening and closing member 75 in the lower position are in an intercepted and blocked state, the flue gas entering the linkage plate 73 below can only enter the concentration frame 63. Under the current conveying impact, the large particles of impurities attached to the surface of the filter screen 742 and inside the linkage plate 73 can be transported to the concentration frame 63, thereby avoiding the blockage of the filter 74.

[0049] Reference Figure 4 , Figure 6-Figure 7 As shown, the incoming flue gas is filtered and purified by the filtering and purification module 8, and the filtering and purification module 8 includes a diverter head 81, a plugging head 82, a sealing assembly 83, a secondary filter element 84, and an activated carbon layer 85. The diverter head 81 is installed at the lower end of the inner part of the shell 5, and diverter cavities are symmetrically provided at the left and right ends of the diverter head 81. A plugging head 82 is slidably provided at the middle part of the diverter head 81. A temporary blocking structure is formed between the diverter head 81 and the plugging head 82 to ensure that the flue gas can be blocked in time when the transportation stops. The upper end of the plugging head 82 is installed with a sealing assembly 83, the middle part of the secondary filter element 84 is rotatably provided inside the shell 5, and the activated carbon layer 85 is installed in the middle position of the shell 5; the left and right ends of the sealing assembly 83 are symmetrically provided with exhaust ports, and the upper end of the exhaust port is connected to one side of the sealing plate by a pin shaft.

[0050] In actual operation, when the smoke in the connecting pipe is ejected, the plug 82 is pushed open to allow the smoke to enter the diversion cavity for continued transportation, and then the smoke is filtered and purified by the secondary filter element 84 and the activated carbon layer 85.

[0051] Reference Figure 7 As shown, the present application filters and retains small particle impurities through the filtering and purification module 8. The specific structure is that the secondary filter element 84 includes an extrusion roller 841, a rotating sleeve 842, a rotating frame 843, a second filter screen 844 and a cleaning member 845. The extrusion roller 841 is fixedly installed in the middle of the shell 5. The rotating sleeve 842 coaxially arranged with the extrusion roller 841 is rotatably connected to the shell 5, and a torque spring is connected between the end of the rotating sleeve 842 and the shell 5. The rotating frame 843 is symmetrically installed on the left and right ends of the rotating sleeve 842. The second filter screen 844 is installed at the lower position of the rotating frame 843. The cleaning member 845 is horizontally slidably arranged at the upper position of the rotating frame 843, and a reset spring is connected between the cleaning member 845 and the rotating frame 843. The reset spring plays a role of elastic reset. The cross section of the squeezing roller 841 is a structure that is narrow in the middle and gradually widens on the upper and lower sides. The design of this structure ensures that when the rotating sleeve 842 and the rotating frame 843 rotate synchronously, the cleaning member 845 that is always attached to the surface of the squeezing roller 841 can slide on the rotating frame 843. The end of the cleaning member 845 close to the squeezing roller 841 is provided with a drag reduction roller, which is attached to the surface of the squeezing roller 841. The cleaning member 845 is composed of a return frame and a cleaning brush. The return frame is horizontally slidably arranged at the upper position of the rotating frame 843. Cleaning brushes are evenly arranged on the return frame to facilitate ejecting attached impurities. An arc groove is opened on the middle side wall of the shell 5, and the outer end face of the return frame is attached to the inner wall of the arc groove to improve the degree of fit between the two.

[0052] During actual operation, small particles of impurities in the flue gas are intercepted by the filter mesh 844, so that the small particles of impurities are attached to the lower surface of the filter mesh 844, which is prone to blockage. With the subsequent transportation of flue gas, the blocked filter mesh 844 causes angle shaking due to resistance. During the shaking process, the contact between the surface of the extrusion roller 841 and the drag reduction roller on the cleaning member 845 causes the cleaning member 845 to slide on the rotating frame 843, and the moving cleaning member 845 pokes and cleans the filter mesh 844, thereby pushing impurities attached to the filter mesh 844 downward, reducing blockage. After the subsequent flue gas transportation stops, the shell 5 can be opened to centrally clean the impurities that have fallen on the sealing component 83.

[0053] Reference Figure 2 , Figure 8As shown, the wet filtration module 9 includes an internal frame 91, a connecting frame 92, a piston plate 93, a cam member 94, and a water delivery assembly 95. The internal upper end of the housing 5 is internally provided with an internal frame 91, the inner wall of the internal frame 91 is paved with a sponge layer, a connecting frame 92 is fixedly installed above the housing 5, a piston plate 93 is slidably arranged inside the connecting frame 92, an elastic telescopic rod is connected between the piston plate 93 and the connecting frame 92, and a cam member 94 used in cooperation with the piston plate 93 for extrusion is installed on the shaft body. The initial state of the cam member 94 is horizontally arranged, and it is still in a horizontal arrangement after rotating 180 degrees following the conveyor belt, but it forms a round of extrusion, lifting and resetting operation for the piston plate 93, a conveyor belt is connected between the shaft body and the rotating roller 71, and a water inlet is provided at the rear end of the lower side of the internal connection frame 92, and the water inlet is connected to the water delivery assembly 95. A water delivery cavity is provided at the upper interlayer position of the housing 5, the water delivery cavity is connected to the connecting frame 92, and a water through hole is provided between the water delivery cavity and the internal frame 91.

[0054] In actual operation, when the rotating roller 71 rotates, the shaft body rotates synchronously driven by the conveyor belt, thereby driving the cam member 94 to rotate 180 degrees. The rotating cam member 94 squeezes the piston plate 93 downward, thereby squeezing the purifier in the lower half of the connecting frame 92 into the water delivery cavity and then squeezed out from the water hole, thereby wetting the sponge layer. The smoke temporarily retained at the upper end of the shell 5 contacts the sponge layer to form a purification process, and then the purified smoke is discharged from the outlet.

[0055] The implementation principle of this embodiment is:

[0056] Step 1: Place the workpiece plate of the waterjet cutting robot in the cutting area and position it;

[0057] Step 2: The base guide rail 1, the beam guide rail 2, and the driving module 3 cooperate to drive the plasma cutting module 4 to move in the X and Y directions, and the plasma cutting module 4 is lifted and lowered in the Z direction, so as to perform plasma cutting on the plate;

[0058] Step 3: The flue gas generated during the cutting process enters the inlet 6, and then passes through the filter group 7, the filter purification module 8, and the wet filter module 9 in sequence before being purified and discharged. The large particles of impurities in the flue gas are intercepted and regularly discharged by the filter group 7, and the small particles of impurities are intercepted and retained by the filter purification module 8. The specific organic waste gas (such as organic solvent volatiles) in the flue gas is adsorbed by activated carbon, and then the dust in the flue gas is wet-attached and the flue gas is purified by the wet filter module 9;

[0059] Step 4: The filtered and purified smoke is discharged from the outlet.

[0060] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
