Description

Technical Field

[0001] This utility model relates to the field of metal parts processing technology, specifically to an automatic dust collection device for metal parts. Background Technology

[0002] Metal parts processing requires grinding, which generates a lot of dust. Long-term inhalation of this dust can cause it to accumulate in the lungs, leading to respiratory diseases such as pneumoconiosis, which seriously endangers the health of operators. At the same time, if metal dust accumulates inside or around electrical equipment, it may enter the gaps and interfaces of the equipment, affecting its normal operation. Therefore, effective dust removal is necessary during the grinding process.

[0003] In traditional factories, it is impossible to ensure that every piece of equipment has a dust collection device on its side during grinding operations. As a result, the dust generated during the grinding process cannot be fully absorbed. At the same time, the dust collected by the dust collection device is not effectively treated and is directly discharged into the atmosphere, causing pollution to the external environment and reducing the effectiveness of dust collection.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] This utility model discloses an automatic dust collection device for metal parts.

[0023] This utility model provides an automatic dust collection device for metal parts as shown in Figures 1-4, including multiple first dust collection mechanisms 1, second dust collection mechanisms 2, filter mechanisms 3 and exhaust pipes 4 arranged in an array. The exhaust pipes 4 are connected to the filter mechanisms 3, and an exhaust hopper 5 is connected to the top of the exhaust pipes 4. The exhaust hopper 5 is arranged with the air outlet direction facing upward.

[0024] The lower end of the filter mechanism 3 is connected to an air inlet pipe 6, and the wall of the air inlet pipe 6 is connected to multiple first air guide pipes 7. The first air guide pipes 7 are connected to the second dust collection mechanism 2. The inlet of the air inlet pipe 6 is connected to a second air guide pipe 8, and the second air guide pipe 8 is connected to the first dust collection mechanism 1. Two adjacent second air guide pipes 8 are connected end to end.

[0025] The second dust collection mechanism 2 includes a frame 9 and a housing 10. A dust collection pipe 11 is connected to the lower end of the outer wall of the housing 10. A valve pipe 12 is connected to the end of the dust collection pipe 11 away from the housing 10. A valve head 13 is connected to the top of the valve pipe 12. A first exhaust fan 14 is connected to the end of the valve pipe 12 away from the dust collection pipe 11. An air supply hopper 15 is connected to the air outlet of the first exhaust fan 14. The air supply hopper 15 and the first exhaust fan 14 are connected via a flange. The end of the air supply hopper 15 away from the first exhaust fan 14 is connected to the upper end of the first air guide pipe 7. When the first exhaust fan 14 is started, a negative pressure is formed around the housing 10. Dust generated from grinding metal parts is drawn in through the dust collection pipe 11 connected to the lower end of the outer wall of the housing 10 under this negative pressure. The dust-laden air then enters the valve pipe 12 and the valve head 13 after passing through the dust collection pipe 11. It can be used to regulate gas flow, etc. Then, under the action of the first exhaust fan 14, the dust-laden air flows from the valve pipe 12 into the air outlet of the first exhaust fan 14, and through the air supply hopper 15 connected thereto, it finally enters the first air guide pipe 7 connected to the air supply hopper 15.

[0026] The first dust collection mechanism 1 includes a grinding frame 17. The bottom and sides of the grinding frame 17 are connected to a third air duct 18, which is connected to a second air duct 8. A second exhaust fan 19 is fixedly embedded inside the third air duct 18. Multiple dust collection holes 20 are opened on the inner side wall and bottom of the grinding frame 17. When the second exhaust fan 19 is started, a negative pressure is formed inside the grinding frame 17. Dust generated by the grinding of metal parts in the grinding frame 17 is sucked in through the multiple dust collection holes 20 opened on the inner side wall and bottom of the grinding frame 17 due to the negative pressure. The dust-laden air is sucked in through the third air duct 18 and flows into the second air duct 8 connected to the third air duct 18 under the action of the second exhaust fan 19.

[0027] The filtration mechanism 3 includes a water tank 21. A cover plate 22 is fixedly installed on the top of the water tank 21, and the cover plate 22 is bolted to the top of the water tank 21. An exhaust pipe 4 is connected to the top of the water tank 21. A guide plate 23 is fixedly installed on the inner wall of the water tank 21, and multiple water curtains 16 are fixedly installed on the inner wall of the water tank 21. An air inlet pipe 6 is connected to the lower side of the water tank 21. Dust-laden air from the first air guide pipe 7 and the second air guide pipe 8 enters the water tank 21 through the air inlet pipe 6 connected to the lower end of the filtration mechanism 3. The guide plate 23 on the inner wall of the water tank 21 guides the flow path of the dust-laden air, allowing it to come into more full contact with the multiple water curtains 16 fixedly installed on the inner wall of the water tank 21. The water curtains 16 can adsorb dust, causing the dust to settle in the water, thereby purifying the dust-laden air. The air purified by the filtration mechanism 3 then passes through the water tank 21. The exhaust pipe 4, which connects to the top, then discharges air from the exhaust hopper 5, which is connected to the top of the exhaust pipe 4. The exhaust direction of the exhaust hopper 5 is upward, which is conducive to the diffusion of purified air and reduces the impact on the surrounding environment. At the same time, the two adjacent second air guide pipes 8 are connected end to end, which may help to make the airflow among the multiple first vacuuming mechanisms 1 more balanced.

[0028] When automatic grinding of metal parts is required, the workpiece in the second dust collection mechanism of the metal parts is automatically ground. During the grinding process, the first exhaust fan 14 is started, so that the dust generated during the grinding process enters the valve pipe 12 through the dust collection pipe 11, and enters the first air guide pipe 7 through the air supply hopper 15 with the guidance of the first exhaust fan 14. The second exhaust fan 19 is started, so that the dust generated during manual grinding dust collection can be sucked into the third air guide pipe 18 through the dust collection hole 20 and flow into the second air guide pipe 8. Finally, it mixes with the dust in the first air guide pipe 7 and then flows into the exhaust pipe 6. After the dust is sucked into the exhaust pipe 6, the dust enters the water tank 21. At this time, multiple water curtains 16 are started, so that the dust is guided by the guide plate 23 and treated by the dust suppression of one side of the multiple water curtains 16, so that the dust is effectively cleaned. The dust-removed gas is discharged out through the exhaust pipe 4 after passing through the water curtain 16.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, 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.
