Technical Field
[0001] This invention relates to the field of dust removal equipment technology, and in particular to a dust removal device for mechanical and electronic production. Background Technology
[0002] Dust removal devices for mechanical and electronic manufacturing are high-efficiency air purification equipment specifically designed for the mechanical and electronic manufacturing industry. During the mechanical and electronic manufacturing process, a large amount of fine dust and particulate matter is generated. These pollutants not only harm the health of employees but may also affect the normal operation of equipment and product quality. This dust removal device, with its advanced technology, can quickly capture and separate various types of dust in the air, effectively purifying the production environment. It possesses powerful suction and a precise filtration system, capable of efficiently treating dust of different particle sizes, ensuring that the emitted air meets environmental standards. Furthermore, it operates stably, is easy to maintain, and can adapt to the needs of long-term continuous operation, creating a clean and safe production space for mechanical and electronic manufacturing enterprises and helping them achieve green and sustainable development.
[0003] In the actual use of existing equipment, the dust generated during the grinding and polishing process consists of metal dust such as iron filings and stainless steel filings produced by grinding wheels. In the operating environment, static electricity has a significant impact on metal dust. Metal dust itself is active, and the generation of static electricity makes it easier for the particles to accumulate charges due to friction and collision. This not only makes the dust more easily suspended and dispersed, increasing its concentration in the air, but also the electric sparks generated by electrostatic discharge are very likely to become ignition sources. Therefore, a dust removal device for mechanical and electronic production is proposed. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies where the dust generated during grinding and polishing processes consists of metal dust such as iron filings and stainless steel filings produced by grinding wheels. In the operating environment, static electricity has a significant impact on metal dust. Metal dust itself is highly reactive, and the generation of static electricity makes it easier for the particles to accumulate charges due to friction and collision. This not only makes the dust more easily suspended and dispersed, increasing its concentration in the air, but also the electric sparks generated by electrostatic discharge are very likely to become ignition sources. Therefore, this invention proposes a dust removal device for mechanical and electronic production.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dust removal device for mechanical and electronic production includes a dust removal shell, a dust removal mechanism, a metal screening mechanism, and a water circulation assembly. A spiral guide plate is fixedly connected inside the dust removal shell. A first motor is installed inside the spiral guide plate. A first transmission wheel is installed at the output end of the first motor. A transmission belt is driven by the first transmission wheel. A second transmission wheel is driven by the transmission belt. A rotating shaft is fixedly connected to the second transmission wheel. The rotating shaft is rotatably connected to an ion air duct. The ion air duct is fixedly connected to the upper part of the dust removal shell. An ion fan is installed at the front end of the ion air duct. Fan blades are installed inside the ion fan and are fixedly connected to the rotating shaft. A mixing duct is fixedly connected to one side of the ion air duct, and a spiral air duct is fixedly connected to the rear end of the mixing duct. The spiral air duct is located at the rear end of the dust removal housing, and the front end of the mixing duct is fixedly connected to the dust removal housing. Metal dust generated during the grinding and polishing process is sucked in and purified by the dust removal mechanism before being discharged. Part of the discharged air is sent into the mixing duct through the spiral air duct. At the same time as the dust removal mechanism is working, the second motor synchronously drives the fan blades to rotate. The rotation of the fan blades drives the air containing positive and negative ions into the mixing duct, where it mixes with the humid air sent in through the spiral air duct. Finally, the air is introduced into the front end of the dust removal housing to mix with the metal dust, neutralizing the electrostatic charge on the surface of the metal dust.
[0006] The above technical solution further includes: The dust removal mechanism includes an impeller located at the output end of a first motor. The impeller is rotatably connected to the dust removal housing and to a spiral guide plate. The impeller rotates under the drive of the first motor, and in conjunction with the spiral guide plate's spiral guiding effect, it can better guide airflow and enhance the dust removal mechanism's ability to suck up and purify metal dust.
[0007] A dehydration tank is provided at one end of the first motor near the first transmission wheel. The dehydration tank is rotatably connected to the dust collector housing. A wastewater tank is provided on the upper part of the dehydration tank. The dehydration tank can further dehydrate the air after preliminary treatment. The wastewater tank is used to collect the wastewater generated during the dehydration process, ensuring the smooth operation of the entire dust removal process.
[0008] The metal screening mechanism includes a metal separation barrel fixedly connected to the bottom of the dust removal housing, a separation housing fixedly connected to the bottom of the metal separation barrel, a second motor installed inside the separation housing, and a screening component installed at the output end of the second motor. Through the cooperation of the metal separation barrel and the separation housing, and the screening component driven by the second motor, the metal screening mechanism can effectively screen metal dust and separate metal particles of different sizes.
[0009] The screening assembly includes a first gear located at the output end of a second motor, which meshes with a second gear. The second gear is rotatably connected to the separation housing. The meshing connection between the first gear and the second gear makes the screening process more stable and reliable, ensuring the accuracy and consistency of the screening effect.
[0010] The second gear is meshed with a third gear, and a second connecting shaft is fixedly connected to the upper part of the third gear. The second connecting shaft is rotatably connected to the separation housing. The meshing of the third gear with the second gear and the rotatable connection between the second connecting shaft and the separation housing further enhance the stability and flexibility of the screening assembly, making the screening process more efficient.
[0011] The first gear is fixedly connected to a first connecting shaft, and the first connecting shaft is rotatably connected to a second connecting shaft. The rotatable connection between the first connecting shaft and the second connecting shaft provides more possibilities for movement of the screening component, which helps to better realize the screening function of metal dust.
[0012] An inner filter screen is fixedly connected to the upper part of the first connecting shaft, and an outer filter screen is fixedly connected to the upper part of the second connecting shaft. The outer filter screen and the inner filter screen are rotatably connected. The diameter of the filter holes at the upper part of the inner filter screen is larger than that at the upper part of the outer filter screen. The different filter hole diameters of the outer and inner filter screens enable the screening component to classify and screen metal dust according to the particle size, thereby improving the screening accuracy and effect.
[0013] A water pump is installed at the front end of the metal separation tank, and a water spray pipe is installed at the output end of the water pump. The end of the water spray pipe away from the water pump is fixedly connected to the dust removal housing. A water pipe can be connected to the upper part of the water spray pipe to provide the main water source. The water pump and water spray pipe constitute part of the water circulation component. By connecting the water pipe to provide the main water source, the necessary water resources can be provided for the entire dust removal device, ensuring the smooth operation of the dust removal and screening process.
[0014] The present invention has the following beneficial effects: 9. In this invention, a large amount of metal dust is generated during the grinding and polishing processes in mechanical and electronic production. A dust removal mechanism can draw the dust into the dust removal housing. During the suction process, a water spray pipe located at the front end of the dust removal housing sprays water mist onto the dust. The water mist initially mixes with the metal dust at the front end of the dust removal housing. Then, a spiral guide plate guides the dust-laden water flow to the inner wall of the dust removal housing, causing the water flow and metal dust to collide with the inner wall, thus further mixing. Finally, a dehydration tank separates the dust-laden water flow from the air, resulting in the discharge of clean and moist water. The exhaust air is introduced into the mixing duct through a spiral duct at the rear of the dust collector housing. During the dust removal process, the ion fan generates positive and negative ions by ionizing the air with high voltage. The dust removal mechanism can simultaneously drive the fan blades inside the ion fan to rotate, thereby sending the air containing positive and negative ions into the mixing duct. In the mixing duct, the humid air and the ion-containing air are mixed and finally sent to the front of the dust collector housing to mix with the sucked-in metal dust, thereby neutralizing the static charge on the surface of the metal dust, preventing spark discharge caused by static accumulation, and reducing the risk of ignition.
[0015] 10. In this invention, the water containing metal dust discharged from the dehydration tank enters the metal separation tank. By activating the second motor installed inside the separation shell, the first connecting shaft and the second connecting shaft can be driven to rotate in opposite directions on the same axis. The rotation of the first connecting shaft and the second connecting shaft can drive the inner filter screen and the outer filter screen to rotate respectively, thereby performing multi-stage screening of the metal dust in the water. The clean water after screening can be pumped into the spray pipe, thereby realizing water circulation and reducing water consumption. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Example 1 like Figures 1-7 As shown, a dust removal device for mechanical and electronic production includes a dust removal housing 1, a dust removal mechanism, a metal screening mechanism, and a water circulation assembly. A spiral guide plate 11 is fixedly connected inside the dust removal housing 1. A first motor 14 is installed inside the spiral guide plate 11. A first transmission wheel 17 is installed at the output end of the first motor 14. The first transmission wheel 17 is driven by a transmission belt 15. The transmission belt 15 is driven by a second transmission wheel 18. A rotating shaft 19 is fixedly connected to the second transmission wheel 18. The rotating shaft 19 is rotatably connected to an ion duct 4. The ion duct 4 is fixedly connected to the upper part of the dust removal housing 1. An ion fan 5 is installed at the front end of the ion duct 4. Fan blades 16 are installed inside the ion fan 5. The fan blades 16 are fixedly connected to the rotating shaft 19. A fixed connection is made between the ion air duct 4 and the mixing air duct 3. The rear end of the mixing air duct 3 is fixedly connected to the spiral air duct 2, which is located at the rear end of the dust removal housing 1. The front end of the mixing air duct 3 is fixedly connected to the dust removal housing 1. The metal dust generated during the grinding and polishing process is sucked in and purified by the dust removal mechanism before being discharged. Part of the discharged air is sent into the mixing air duct 3 through the spiral air duct 2. At the same time as the dust removal mechanism is working, the second motor 24 synchronously drives the fan blade 16 to rotate. The rotation of the fan blade 16 drives the air containing positive and negative ions into the mixing air duct 3, where it mixes with the humid air sent in through the spiral air duct 2. Finally, it is introduced into the front end of the dust removal housing 1 to mix with the metal dust and neutralize the static charge on the surface of the metal dust.
[0020] The dust removal mechanism includes an impeller 10 located at the output end of the first motor 14. The impeller 10 is rotatably connected to the dust removal housing 1 and to the spiral guide plate 11. The impeller 10 rotates under the drive of the first motor 14. With the spiral guiding effect of the spiral guide plate 11, it can better guide the airflow and enhance the dust removal mechanism's ability to suck up and purify metal dust. A dehydration tank 12 is located at one end of the first motor 14 near the first transmission wheel 17. The dehydration tank 12 is rotatably connected to the dust removal housing 1. A wastewater tank 13 is provided on the upper part of the dehydration tank 12. The dehydration tank 12 can further dehydrate the air after preliminary treatment. The wastewater tank 13 is used to collect the wastewater generated during the dehydration process to ensure the smooth operation of the entire dust removal process.
[0021] In this embodiment, a large amount of metal dust is generated during the grinding and polishing processes in mechanical and electronic production. Starting the first motor 14 can drive the impeller 10 and the dewatering tank 12 to rotate. The rotation of the impeller 10 can suck in the metal dust. During the suction process, the water spray pipe 9 set at the front end of the dust collector housing 1 can spray water mist onto the dust. The water mist is initially mixed with the metal dust at the front end of the dust collector housing 1. Then, the water containing dust is guided to the inner wall of the dust collector housing 1 by the spiral guide plate 11, so that the water flow collides with the metal dust and the inner wall of the dust collector housing 1, thereby achieving further mixing. The water flow carrying the metal dust enters the dewatering tank 12. After the dewatering tank 12 rotates, the water flow is thrown out through the sewage tank 13 under the action of centrifugal force, while the separated clean and moist gas is discharged through the rear end of the dust collector housing 1. Some of the discharged air can pass through the rear end of the dust collector housing 1. The spiral air duct 2 at the end is introduced into the mixing air duct 3. During the dust removal process, the ion fan 5 can generate positive and negative ions by ionizing the air with high voltage. The first motor 14 can synchronously drive the first transmission wheel 17 to rotate. The rotation of the first transmission wheel 17 drives the transmission belt 15 to rotate. The rotation of the transmission belt 15 drives the second transmission wheel 18 to rotate. The rotation of the second transmission wheel 18 can drive the fixedly connected rotating shaft 19 to rotate, which in turn drives the fan blades 16 set inside the ion fan 5 to rotate. Thus, the air containing positive and negative ions is sent into the mixing air duct 3. In the mixing air duct 3, the humid air and the ion-containing air are mixed and finally sent into the front end of the dust collector housing 1 to mix with the sucked metal dust, thereby neutralizing the static charge on the surface of the metal dust, preventing spark discharge caused by static accumulation, and reducing the risk of ignition source.
[0022] Example 2 like Figures 1-7As shown, the metal screening mechanism includes a metal separation barrel 6 fixedly connected to the bottom of the dust removal housing 1, a separation housing 7 fixedly connected to the bottom of the metal separation barrel 6, a second motor 24 installed inside the separation housing 7, and a screening component installed at the output end of the second motor 24. Through the cooperation of the metal separation barrel 6 and the separation housing 7, and the screening component driven by the second motor 24, the metal screening mechanism can effectively screen metal dust and separate metal particles of different sizes. The screening component includes a first gear 25 installed at the output end of the second motor 24, a second gear 26 meshing with the first gear 25, and a rotatable connection between the second gear 26 and the separation housing 7. The meshing connection of the first gear 25 and the second gear 26 makes the screening process more stable and reliable, ensuring the accuracy and consistency of the screening effect.
[0023] The second gear 26 is meshed with the third gear 27. A second connecting shaft 23 is fixedly connected to the upper part of the third gear 27. The second connecting shaft 23 is rotatably connected to the separation housing 7. The meshing of the third gear 27 with the second gear 26 and the rotatable connection between the second connecting shaft 23 and the separation housing 7 further enhance the stability and flexibility of the screening assembly, making the screening process more efficient. The first gear 25 is fixedly connected to the upper part of the first connecting shaft 22. The first connecting shaft 22 is rotatably connected to the second connecting shaft 23. This rotatable connection provides the screening assembly with more movement possibilities, helping to better achieve the screening function of metal dust. An inner filter screen 21 is fixedly connected to the upper part of the first connecting shaft 22, and the upper part of the second connecting shaft 23 is fixedly connected to... An outer filter screen 20 is connected to an inner filter screen 21, which is rotatably connected. The diameter of the filter holes on the upper part of the inner filter screen 21 is larger than that on the upper part of the outer filter screen 20. The different filter hole diameters of the outer filter screen 20 and the inner filter screen 21 enable the screening component to classify and screen metal dust according to the particle size, thereby improving the screening accuracy and effect. A water pump 8 is installed at the front end of the metal separation tank 6, and a water spray pipe 9 is installed at the output end of the water pump 8. The end of the water spray pipe 9 away from the water pump 8 is fixedly connected to the dust collector housing 1. A water pipe can be connected to the upper part of the water spray pipe 9 to provide the main water source. The water pump 8 and the water spray pipe 9 constitute part of the water circulation component. By connecting the water pipe to provide the main water source, the necessary water resources can be provided for the entire dust removal device, ensuring the smooth operation of the dust removal and screening process.
[0024] In this embodiment, the water containing metal dust discharged from the dehydration tank 12 impacts the inner wall of the dust removal housing 1 and slides into the metal separation tank 6. By activating the second motor 24 installed inside the separation housing 7, the first gear 25 can be driven to rotate. The rotation of the first gear 25 drives the meshing second gear 26 to rotate, and the rotation of the second gear 26 drives the meshing third gear 27 to rotate. The rotation of the first gear 25 and the third gear 27 can drive the first connecting shaft 22 and the second connecting shaft 23 to rotate in opposite directions. The rotation of the first connecting shaft 22 and the second connecting shaft 23 can drive the inner filter screen 21 and the outer filter screen 20 to rotate respectively, thereby performing multi-stage screening of the metal dust in the water. The clean water after screening can be sent into the spray pipe 9 through the water pump 8, thereby realizing water circulation and reducing water consumption.
