Description

Technical Field

[0001] The invention relates to the technical field of smoke processing equipment, and in particular to smoke processing equipment for a CNC machining center. Background Art

[0002] In modern manufacturing, CNC (computer numerical control) machine tools are widely used in precision processing of metals, plastics and other materials. However, a large amount of smoke, dust and harmful gases will be generated during CNC processing. These pollutants not only affect the air quality of the working environment, but may also cause harm to the health of operators. Therefore, fume purification equipment has become an indispensable supporting device for CNC machine tools.

[0003] At present, the common solution is to configure a flue gas purification machine for each CNC processing machine. Although this configuration can effectively deal with the smoke generated by a single device, it also has the following significant problems: 1. Troublesome layout: Each CNC machine tool needs to be equipped with a separate fume purifier, which leads to complex equipment layout on site, cumbersome pipeline layout, and occupies a lot of space. This problem is particularly prominent in workshops where multiple machine tools are running at the same time. 2. High installation cost: The purchase, installation and maintenance of each flue gas purifier require high costs; for a production workshop with multiple CNC machine tools, this decentralized purification solution will significantly increase equipment investment and operating costs; 3. Low energy efficiency: Each flue gas purifier operates independently, which cannot achieve centralized management and optimal utilization of energy, resulting in high overall energy consumption, which is not in line with the development trend of green manufacturing and energy conservation and emission reduction; 4. Inconvenient maintenance and management: Scattered purification equipment needs to be maintained and serviced separately, which increases the difficulty of management and maintenance costs. At the same time, the purification effect may also be affected due to untimely maintenance; In summary, the existing solution of equipping each CNC machine tool with a flue gas purifier has problems such as complicated layout, high cost, low energy efficiency and inconvenient maintenance and management.

The tube body bracket 73 can lift and restrain the liquid guiding hose 72, and the second winding wheel 74 releases the liquid guiding hose 72. In this way, the waste liquid in the receiving box 45 can be discharged to the recovery box 76 through the fourth conduit 71 and the liquid guiding hose 72.

[0034] In order to enable the purification exhaust machine 8 to effectively separate the oil mist, the following solution is given: In the present embodiment, the purification exhaust machine 8 comprises a main box body 81, an air supply chamber 811 is provided inside the main box body 81, a flushing liquid tank 812 and an oil tank 813 arranged in parallel are provided at the bottom of the air supply chamber 811, a primary 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 chamber 811 along the conveying direction, a flushing plate 82 is installed on the outer top of the primary filter plate 83, a horizontal air guide plate 814 is provided at the bottom end of the primary filter plate 83, and a drain port 8141 is provided at a position relative to the horizontal air guide plate 814 and the primary filter plate 83; the primary filter plate 83, the flow blocking component 84 and the ionizer 85 are all placed above the oil tank 813, and the flushing liquid tank 812 is located at the front end of the oil tank 813; the working modes of the purification exhaust machine 8 include mode one and mode two; In the first mode, the flow-blocking component 84 and the primary filter plate 83 are arranged at intervals, and the smoke first passes through the primary filter plate 83, and then enters the ionizer 85 through the bottom of the flow-blocking component 84; the oil attached to the primary filter plate 83, the flow-blocking component 84 and the ionizer 85 drips into the oil tank 813; In mode 2, the flow-blocking component 84 is in contact with the primary filter plate 83 , and the flushing plate 82 discharges flushing water onto the primary filter plate 83 and the flow-blocking component 84 , and the flushing water is guided to the flushing liquid tank 812 by the flow-blocking component 84 .

[0035] In the above scheme: Large particles in the derived smoke can be filtered by the primary filter plate 83, and then the airflow is blocked by the baffle 84, and the liquid adheres to the baffle 84. Then the smoke passes through the bottom of the baffle 84 and enters the ionizer 85. The ionizer 85 can generate an electric field to absorb the oil, and finally, the activated carbon filter plate 87 performs the final filtration; The oil attached to the primary filter plate 83, the flow blocking component 84 and the ionizer 85 falls into the oil tank 813 at the bottom, where the oil is gathered and can be used again after sedimentation and filtration. The baffle component 84 can be moved at a fixed time, and the baffle component 84 is attached to the inner side of the primary filter plate 83. Then the flushing plate 82 discharges the oil cleaning liquid onto the primary filter plate 83. In this way, the primary filter plate 83 and the baffle component 84 can be flushed simultaneously to remove the attached impurities on the primary filter plate 83 and the baffle component 84, thereby ensuring the filtering and baffle effect without disassembly and cleaning. At the same time, the baffle component 84 can also block the flushing liquid from the inside to prevent the flushing liquid from splashing inward. The baffle component 84 can also guide the flushing liquid so that the flushing liquid is discharged into the flushing liquid tank 812 instead of entering the oil tank 813 below, thereby preventing the flushing liquid from contaminating the oil tank 813.

[0036] In this embodiment, the flow blocking component 84 includes an upper plate body 841, the top end of the upper plate body 841 is slidably embedded in the top moving groove 815 at the top of the air supply chamber 811, and a third driving rod 843 for driving the upper plate body 841 to translate is installed inside the top moving groove 815, and the bottom end of the upper plate body 841 is symmetrically provided with side plates 8411, and a rotating column 8421 is rotatably connected between the two groups of side plates 8411, and the side wall of the rotating column 8421 is connected to the lower plate body 842, and driven gears 8422 are provided at both ends of the rotating column 8421, and the driven gear 8422 is located on the outside of the side plate 8411 and embedded in the side moving groove 816 of the side wall of the air supply chamber 811, and a tooth plate 8161 meshing with the driven gear 8422 is provided at the top of the inner part of the side moving groove 816; In the first mode, the lower plate 842 is horizontally oriented toward the ionizer 85; In mode 2, the lower plate 842 is tilted and placed at the bottom of the drain port 8141 , and the lower plate 842 guides the flushing water to the flushing liquid tank 812 .

[0037] In the above scheme: the baffle component 84 is designed to be two components, and the lower plate 842 can automatically rotate when the upper plate 841 translates to meet the working requirements of mode 1 and mode 2; In mode 1, the lower plate 842 is horizontally oriented toward the ionizer 85, so that the oil attached to the windward surface of the upper plate 841 can drip into the oil tank 813 under the action of its own weight, and the lower plate 842 will not interfere. At the same time, when the smoke enters the ionizer 85 upward, the lower plate 842 can play a certain blocking and dispersing effect, thereby playing a spoiler effect; In mode two, the third driving rod 843 drives the upper plate 841 to move. During the movement, the driven gear 8422 moves along the side moving groove 816, and the tooth plate drives the driven gear 8422 to rotate, so that the lower plate 842 rotates toward the primary filter plate 83. When the upper plate 841 is in contact with the primary filter plate 83, the lower plate 842 is tilted and placed below the drain port 8141, and the flushing water is discharged into the flushing liquid tank 812 through the drain port 8141 and the lower plate 842.

[0038] 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 842 rotates clockwise, it passes over the oil tank 813 but does not come into contact with the oil. The oil is located below the movement trajectory. The flushing liquid in the flushing tank 812 will also be discharged regularly.
