Description

Technical Field

[0001] The present invention relates to the technical field of smoke treatment equipment, and particularly to a smoke treatment equipment for a CNC machining center. Background Art

[0002] In modern manufacturing, CNC (Computer Numerical Control) machining tools are widely used in the precision machining of materials such as metals and plastics. However, a large amount of smoke, dust, and harmful gases are generated during the CNC machining process. These pollutants not only affect the air quality of the working environment but may also pose a hazard to the health of operators. Therefore, flue gas purification equipment has become an indispensable supporting device for CNC machining tools.

[0003] Currently, a common solution is to configure a separate flue gas purifier for each CNC machining tool. Although this configuration method can effectively handle the smoke generated by a single device, it also has the following significant problems:

[0004] 1. Troublesome layout: A separate flue gas purifier needs to be installed for each CNC machine tool, resulting in a complex layout of on-site equipment, cumbersome pipeline layout, and occupying a large amount of space. This problem is particularly prominent in workshops where multiple machine tools are operating simultaneously.

[0005] 2. High layout cost: The procurement, installation, and maintenance of each flue gas purifier require a relatively high cost. For a production workshop with multiple CNC machine tools, this decentralized purification solution will significantly increase equipment investment and operating costs.

[0006] 3. Low energy efficiency: Each flue gas purifier operates independently, and centralized management and optimized utilization of energy cannot be achieved, resulting in a relatively high overall energy consumption, which does not conform to the development trend of green manufacturing and energy conservation and emission reduction.

[0007] 4. Inconvenient maintenance and management: Decentralized purification equipment needs to be maintained and serviced separately, increasing management difficulty and maintenance costs. At the same time, the purification effect may also be affected due to untimely maintenance.

[0008] In summary, the existing solution of configuring a separate flue gas purifier for each CNC machining tool has problems such as troublesome layout, high cost, low energy efficiency, and inconvenient maintenance and management. Summary of the Invention

Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0056] To solve the technical problems in the background art, the following is a smoke treatment device for a CNC machining center:

[0057] Combined with Figures 1-14 As shown, a smoke treatment device for a CNC machining center provided by the present invention includes a main smoke guiding assembly 1, which includes a main smoke guiding pipe 11, a fixing frame 12, and a blower 13. The main smoke guiding pipe 11 is horizontally arranged on the top surfaces of multiple machine tools 9. The side part of the main smoke guiding pipe 11 is fixed to the tops of multiple machine tools 9 through the fixing frame 12. A blower 13 is installed outside the air supply end of the main smoke guiding pipe 11. An air valve 5 is installed at the end of the air supply end of the main smoke guiding pipe 11. Multiple first conduits 14 are vertically arranged on the bottom surface of the main smoke guiding pipe 11. Multiple first conduits 14 are all connected in parallel to the main smoke guiding pipe 11. Each machine tool 9 corresponds to a group of first conduits 14;

[0058] A movable transfer assembly 3, which is installed on the top surface of the machine tool 9, and the top end of the movable transfer assembly 3 is docked with the first conduit 14;

[0059] An air extraction assembly 2, which is installed inside the machine tool 9, is used to extract machining smoke inside the machine tool 9 in multiple directions, and the output end of the air extraction assembly 2 is connected and communicated with the bottom end of the movable transfer assembly 3;

[0060] A cleaning assembly 6, which is installed at the end of the air valve 5; when the air valve 5 is opened, the cleaning assembly 6 extends into the main smoke guiding pipe 11; when the air valve 5 is closed, the cleaning assembly 6 is stored at the outer end of the air valve 5;

[0061] An unlocking and material receiving assembly 4, which is slidably installed on the side of the main smoke guiding pipe 11, and the unlocking and material receiving assembly 4 is located in front of the moving direction of the cleaning assembly 6;

[0062] A purification and exhaust machine 8, which is communicated with the air outlet end of the main smoke guiding pipe 11, and the purification and exhaust machine 8 is used to filter out particulate matter in the smoke and discharge clean air;

[0063] When the treatment device purifies and exhausts smoke: the air valve 5 is closed, the smoke is introduced into the main smoke guiding pipe 11 through the movable transfer assembly 3 and the first conduit 14, and the blower 13 conveys the smoke to the purification and exhaust machine 8;

[0064] When the processing device cleans the main smoke pipe 11: the air valve 5 is opened, and the cleaning component 6 and the unlocking and material receiving component 4 act synchronously. The cleaning component 6 scrapes the smoke impurities adhering to the inner wall of the main smoke pipe 11 and pushes the smoke particles into the first conduit 14; the unlocking and material receiving component 4 pre-opens each group of movable transfer components 3 and places them below the first conduit 14, so that the smoke impurities in the first conduit 14 can be discharged into the unlocking and material receiving component 4.

[0065] In the above solution:

[0066] 1. One main smoke pipe 11 is provided in parallel with multiple groups of machine tools 9. In this way, the smoke of multiple groups of machine tools 9 can be purified by one purification exhaust machine 8. The pipeline layout of the main smoke component 1 is more convenient and occupies less space. At the same time, it is not necessary to set a purification machine above each machine tool 9, effectively reducing the production cost;

[0067] 2. A blower 13 is configured at one end of the main smoke pipe 11, and an air extraction component 2 is configured above the machine tool 9. Combined with the negative pressure suction provided by the purification exhaust machine 8, there is a blowing structure at all three positions, which can effectively ensure the extraction efficiency of the smoke and meet the use requirements;

[0068] 3. After the main smoke pipe 11 is used for a period of time, some dirt will accumulate inside it. To ensure smooth smoke conduction, an air valve 5 and a cleaning component 6 are added. When the main smoke pipe 11 needs to be cleaned, the air valve 5 is opened, and the cleaning component 6 can enter the main smoke pipe 11 to remove the smoke impurities, realizing automatic cleaning and dredging to ensure smooth smoke exhaust;

[0069] 4. To solve the problem that sewage enters the first conduit 14 during the cleaning process of the cleaning component 6, an unlocking and material receiving component 4 and a separable movable transfer component 3 are provided;

[0070] During daily work, the movable transfer component 3 is docked with the first conduit 14, and the flue gas enters the main smoke pipe 11 through the movable transfer component 3 and the first conduit 14;

[0071] When cleaning the main smoke pipe 11, the unlocking and material receiving component 4 can unlock the movable transfer component 3 in advance and enter below the first conduit 14. In this way, the impurities cleaned by the cleaning component 6 can fall into the unlocking and material receiving component 4 through the first conduit 14, without polluting the machine tool 9. The cleaning and collection process is simple. When the unlocking and material receiving component 4 leaves, the movable transfer component 3 can automatically reset and dock.

[0072] In order to enable the movable transit component 3 and the unlocking and connecting component 4 to achieve the above-mentioned functions of automatic unlocking, connecting, and resetting docking, in the present embodiment, the movable transit component 3 comprises a corrugated sleeve 32, a curved pipe 31, a spring rod 33, a matching inclined plate 35, and a connecting rod 34. The top end of the curved pipe 31 is fixedly connected to the corrugated sleeve 32, and the top of the corrugated sleeve 32 is movably sleeved on the outside of the bottom end of the first conduit 14. Connecting rods 34 are provided on both side walls of the top end of the corrugated sleeve 32, and matching inclined plates 35 are provided on the outer ends of the connecting rods 34. The matching inclined plates 35 are longitudinally distributed with the inclined surfaces facing upwards, and a spring rod 33 is installed at the bottom of each group of matching inclined plates 35. When the corrugated sleeve 32 is retracted downward, the corrugated sleeve 32 is separated from the first conduit 14 to leave an insertion gap, and the spring rod 33 contracts.

[0073] The unlocking material receiving assembly 4 includes a rack 41 and a travel seat 42. The rack 41 is fixedly arranged in the middle of the top surface of the main smoke pipe 11, and the travel seat 42 is meshed and installed on the top of the rack 41. The bottom of the travel seat 42 is symmetrically provided with a guide wheel frame 421, and the guide wheel frame 421 is symmetrically and rollingly arranged on both sides of the rack 41. The side of the travel seat 42 is vertically provided with a first driving rod 43, and the output end of the first driving rod 43 is provided with a hanging arm 44 extending vertically downward. The inner wall of the bottom end of the hanging arm 44 is provided with a material receiving box 45, and the inner end of the material receiving box 45 is symmetrically provided with a resistance rod 46, and the end of the resistance rod 46 is an arc surface; when the material receiving box 45 moves inward, the resistance rod 46 presses down to fit the inclined plate 35.

[0074] In the above scheme:

[0075] When not cleaning, the first driving rod 43 is extended, so that the material receiving box 45 and the abutting rod 46 are placed on one side of the corrugated sleeve 32;

[0076] When pre-unlocked, the travel seat 42 travels along the rack 41, and the guide wheel frame 421 supports and positions the travel seat 42 from both sides. When the abutment rod 46 is aligned with the matching inclined plate 35, the first driving rod 43 contracts, thereby driving the receiving box 45 to move inward, and the arc surface of the end of the abutment rod 46 abuts against the matching inclined plate 35 to move downward and compress the spring rod 33. When the matching inclined plate 35 moves downward, it drives the corrugated sleeve 32 to contract downward through the connecting rod 34, and the corrugated sleeve 32 is separated from the first guide tube 14;

[0077] After the corrugated sleeve 32 is detached, the material receiving box 45 moves to the top of the corrugated sleeve 32 and moves to the bottom of the first conduit 14, so as to prepare for receiving the material.

[0079] In the above scheme: the smoking pipe 25 is designed to be close to the tool seat 91, so that the smoking pipe 25 can directly attract the smoke at the cutting position by negative pressure. At the same time, a gap is left between the second duct 22 and the third duct 23, and the second duct 22 is located at the inner top of the machine tool 9. In this way, the second duct 22 can attract the smoke dispersed inside the machine tool 9 by negative pressure, realizing multi-directional negative pressure exhaust, and the exhaust is more comprehensive and thorough; when the air supply box 21 is working, it can generate negative pressure, so that the smoke can be discharged to the curved pipe 31.

[0081] In the above scheme: the air supply fan 13 is designed to be placed above the main smoke pipe 11, and the end of the main smoke pipe 11 is provided with a rectangular frame 52 and a blocking plate 53, so that when smoke is supplied, the blocking plate 53 is retracted into the rectangular frame 52, thereby blocking the main smoke pipe 11, and the air supply fan 13 can exhaust air, and the airflow enters the main smoke pipe 11 through the side air supply hole 111, thereby realizing end air supply; when cleaning is needed, the second driving rod 54 drives the blocking plate 53 to move outward, so that the cleaning component 6 can enter the main smoke pipe 11.

[0082] In this embodiment, the cleaning component 6 includes a temporary storage bin 61, a moving cart 62, a front scraper ring 63 and a rear scraper ring 64. The moving cart 62 is a rectangular parallelepiped, and multiple sets of walking wheels 621 are installed on the side of the moving cart 62. The front scraper ring 63 is installed at one end of the moving cart 62 and the rear scraper ring 64 is installed at the other end. The temporary storage bin 61 is installed on the outer side of the rectangular frame 52.

[0083] In the above scheme: when cleaning, each walking wheel 621 rotates, and the mobile car 62 can enter the main smoke pipe 11, and the front scraper ring 63 and the rear scraper ring 64 can scrape off the attachments in the main smoke pipe 11 in two passes to ensure the cleaning effect.

[0084] In this embodiment, the cleaning component 6 further includes a first winding wheel 68, a central shaft tube 65, a liquid delivery tube 67, a liquid spraying plate 66, and a liquid storage tank 69. The central shaft tube 65 is rotatably installed in the middle of the interior of the moving trolley 62. The output end of the central shaft tube 65 is connected to the liquid spraying plate 66. The liquid spraying plate 66 is placed on the front side of the front scraping ring 63. The central shaft tube 65 is connected to the liquid delivery tube 67 through a rotary joint. The liquid delivery tube 67 is wound around the first winding wheel 68. A first winding motor is installed at the end of the first winding wheel 68. The inlet end of the liquid delivery tube 67 is connected to the liquid storage tank 69 through a first liquid pumping pump 691.

[0085] In the above solution: The liquid storage tank 69 stores a cleaning agent for cleaning the oil mist. The cleaning agent is led out to the central shaft tube 65 through the first liquid pumping pump 691 and the liquid delivery tube 67, and then the cleaning agent is dispersed and discharged through the liquid spraying plate 66. In this way, the oil liquid can be softened in advance to facilitate the cleaning by the front scraping ring 63. The central shaft tube 65 can rotate, thereby driving the liquid spraying plate 66 to rotate; the winding and releasing of the first winding wheel 68 can adapt to the forward and backward movement of the moving trolley 62.

[0086] In this embodiment, the bottom of the material receiving box 45 is connected to a guiding and discharging component 7. The guiding and discharging component 7 includes a fourth conduit 71, a liquid guiding hose 72, a pipe bracket 73, and a second winding wheel 74. The bottom end of the material receiving box 45 communicates with the fourth conduit 71. The bottom end of the fourth conduit 71 communicates with the liquid guiding hose 72. Multiple groups of pipe brackets 73 are installed on the top surface of each machine tool 9. The top of the pipe bracket 73 is U-shaped. The liquid guiding hose 72 is wound around the outer wall of the second winding wheel 74. A second winding motor is installed at the end of the second winding wheel 74. The outlet end of the liquid guiding hose 72 is connected to a recovery box 76 through a second liquid pumping pump 75. The first winding wheel 68, the second winding wheel 74, the recovery box 76, and the liquid storage tank 69 are all installed in the outer box 9a.

[0087] In the above solution: To discharge the waste liquid in the material receiving box 45, the fourth conduit 71 drives the liquid guiding hose 72 to move outwards. The liquid guiding hose 72 moves along the pipe bracket 73. The pipe bracket 73 can support and restrain the liquid guiding hose 72. The second winding wheel 74 releases the liquid guiding hose 72. In this way, the waste liquid in the material receiving box 45 can be discharged to the recovery box 76 through the fourth conduit 71 and the liquid guiding hose 72.

[0088] To enable the purification and exhaust machine 8 to effectively separate the oil mist, the following solution is given:

[0089] In this embodiment, the purification exhaust machine 8 includes a main box body 81. A air supply cavity 811 is formed inside the main box body 81. A flushing liquid tank 812 and an oil liquid tank 813 arranged side by side are formed at the bottom of the air supply cavity 811. An initial filter plate 83, a flow blocking component 84, an ionizer 85, a main fan 86, and an activated carbon filter plate 87 are sequentially installed inside the air supply cavity 811 along the conveying direction. A flushing plate 82 is installed at the outer top of the initial filter plate 83. A horizontal air guiding plate 814 is provided at the bottom end of the initial filter plate 83. A liquid discharge port 8141 is formed at the position of the horizontal air guiding plate 814 opposite to the initial filter plate 83. The initial filter plate 83, the flow blocking component 84, and the ionizer 85 are all located above the oil liquid tank 813, and the flushing liquid tank 812 is located at the front end of the oil liquid tank 813. The working modes of the purification exhaust machine 8 include Mode 1 and Mode 2.

[0090] In Mode 1, the flow blocking component 84 and the initial filter plate 83 are arranged at intervals. The smoke first passes through the initial filter plate 83 and then enters the ionizer 85 through the space below the flow blocking component 84. The oil liquid attached to the initial filter plate 83, the flow blocking component 84, and the ionizer 85 drops into the oil liquid tank 813.

[0091] In Mode 2, the flow blocking component 84 is attached to the initial filter plate 83. The flushing plate 82 discharges flushing water onto the initial filter plate 83 and the flow blocking component 84, and the flushing water is guided by the flow blocking component 84 to the flushing liquid tank 812.

[0092] In the above solution:

[0093] The large particles in the discharged smoke can be filtered by the initial filter plate 83, and then the airflow is blocked by the flow blocking component 84. The liquid adheres to the flow blocking component 84. Subsequently, the smoke enters the ionizer 85 through the bottom end of the flow blocking component 84. The ionizer 85 can generate an electric field to adsorb the oil liquid. Finally, the activated carbon filter plate 87 performs the final filtration.

[0094] The oil liquid attached to the initial filter plate 83, the flow blocking component 84, and the ionizer 85 drops into the oil liquid tank 813 at the bottom. The oil liquid accumulates in the oil liquid tank 813 and can be reused after sedimentation and filtration.

[0095] The flow blocking component 84 can move regularly. The flow blocking component 84 is attached to the inner side of the initial filter plate 83. Subsequently, the flushing plate 82 discharges the oil liquid cleaning liquid onto the initial filter plate 83. In this way, the initial filter plate 83 and the flow blocking component 84 can be flushed synchronously to remove the attached impurities on the initial filter plate 83 and the flow blocking component 84, ensuring the filtering and blocking effect without disassembly and cleaning. At the same time, the flow blocking component 84 can also block the flushing liquid from the inside to avoid the inward sputtering of the flushing liquid. The flow blocking component 84 can also guide the flushing liquid so that the flushing liquid is discharged into the flushing liquid tank 812 and will not enter the lower oil liquid tank 813, avoiding the pollution of the oil liquid tank 813 by the flushing liquid.

[0096] In this embodiment, the flow blocking member 84 includes an upper plate body 841. The top end of the upper plate body 841 is slidably embedded in the top movement groove 815 at the top of the air supply chamber 811. A third driving rod 843 for driving the horizontal translation of the upper plate body 841 is installed inside the top movement groove 815. Side plates 8411 are symmetrically provided at the bottom end of the upper plate body 841. A rotating column 8421 is rotatably connected between the two groups of side plates 8411. A lower plate body 842 is connected to the side wall of the rotating column 8421. Driven gears 8422 are provided at both ends of the rotating column 8421. The driven gears 8422 are located outside the side plates 8411 and are embedded in the side movement grooves 816 on the side wall of the air supply chamber 811. A toothed plate 8161 meshing with the driven gears 8422 is provided at the inner top of the side movement groove 816;

[0097] In mode one, the lower plate body 842 faces the ionizer 85 horizontally;

[0098] In mode two, the lower plate body 842 is inclined at the bottom of the drain port 8141, and the lower plate body 842 guides the flushing water to the flushing liquid tank 812.

[0099] In the above solution: The flow blocking member 84 is designed as two components. The lower plate body 842 can automatically rotate when the upper plate body 841 translates to meet the working requirements of mode one and mode two;

[0100] In mode one, the lower plate body 842 faces the ionizer 85 horizontally. In this way, the oil adhered to the windward surface of the upper plate body 841 can drip into the oil tank 813 under its own weight, and the lower plate body 842 will not interfere. At the same time, when the smoke enters the ionizer 85 upward, the lower plate body 842 can play a certain role in blocking and dispersing, achieving a flow disturbance effect;

[0101] In mode two, the third driving rod 843 drives the upper plate body 841 to move. During the movement, the driven gear 8422 moves along the side movement groove 816, and the toothed plate drives the driven gear 8422 to rotate self - sufficiently, so that the lower plate body 842 rotates to face the primary filter plate 83. When the upper plate body 841 fits with the primary filter plate 83, the lower plate body 842 is inclined below the drain port 8141, and the flushing water is led to the flushing liquid tank 812 through the drain port 8141 and the lower plate body 842.

[0102] The liquid level in the oil tank 813 will not be too high. After receiving a certain amount of oil, it will be discharged for recycling. When the lower plate body 842 rotates clockwise, it passes above the oil tank 813 but does not contact the oil. The oil is located below the movement track; The flushing liquid in the flushing liquid tank 812 will also be discharged regularly.
