Abstract
Description
Technical Field
[0001] This utility model relates to the field of wet dust removal for aluminum-magnesium alloy dust, specifically a wet dust removal device for aluminum-magnesium alloy cutting dust. Background Technology
[0002] With the development of materials science, aluminum-magnesium alloys are increasingly widely used in manufacturing due to their advantages of high strength, low density, good heat dissipation, and corrosion resistance. At the same time, aluminum-magnesium alloys have a high specific strength, meaning a high strength-to-mass ratio, making them suitable for an increasing number of applications requiring load-bearing capacity.
[0003] A search revealed Chinese patent application number CN201811009384, which discloses an explosion-proof wet dust removal device for aluminum and magnesium dust. This device uses a pressure pump to spray a liquid from a storage tank through multiple rotating nozzles into the air inside the workshop. The liquid adsorbs and settles aluminum and magnesium dust particles in the air, and a vacuum cleaner then collects the settled particles, reducing the aluminum and magnesium dust content in the workshop and improving safety. However, this dust removal method still allows aluminum and magnesium dust to spill into the production workshop, as it does not collect the dust at the source, thus posing a certain degree of danger. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model proposes a wet dust removal device for aluminum-magnesium alloy cutting dust. Through the installation of a spray assembly, air duct, bag air filter, and exhaust fan, it can conveniently and promptly collect aluminum-magnesium dust generated during aluminum-magnesium alloy cutting online, preventing explosion accidents.
[0005] The technical solution to achieve the purpose of this utility model is: a wet dust removal device for aluminum-magnesium alloy cutting dust, including a workbench, a cutting tool installed on the workbench, an air duct installed above the cutting tool, an air duct opening near the cutting tool, a sprayer assembly installed at the air duct opening, a bag air filter bolted to the air duct, and an exhaust fan fixedly installed after the bag air filter on the air duct.
[0006] The spray assembly includes a spray nozzle, a spray pipe, a water tank, a water tank cover, and a compressed air pipe; the air duct opening is opened and the spray nozzle is fixedly installed in the opening, the spray nozzle passes through the wall of the air duct opening and is fixedly connected, one end of the spray nozzle outside the air duct opening is fixedly connected to the spray pipe, and the other end of the spray pipe extends to the bottom of the water tank.
[0007] The water tank is fitted with a lid that matches the size of the water tank and can be sealed.
[0008] One end of the compressed air pipe is connected to a compressed air source, and the other end is connected to the inside of the water tank.
[0009] Preferably, the spray nozzle is divided into a fixed end and a spray head. The fixed end of the spray nozzle is fixedly connected to the air duct opening. One end of the fixed end of the spray nozzle is fixedly connected to the spray pipe, and the other end is threadedly connected to the spray head. The spray size can be adjusted by rotating the spray head.
[0010] Preferably, a water level gauge is installed on the side wall of the water tank.
[0011] Preferably, an expansion joint is installed on the air duct before the bag air filter.
[0012] Compared with the prior art, the significant advantages of this utility model are:
[0013] Firstly, this utility model, by setting up a bag-type air filter, can directly filter and collect aluminum and magnesium dust online during the cutting of aluminum and magnesium alloys, avoiding the danger caused by the spillage of aluminum and magnesium dust in the processing workshop; after replacing the bag-type air filter, the bag-type air filter containing aluminum and magnesium dust can be safely disposed of directly.
[0014] Secondly, the aluminum and magnesium dust generated during cutting is directly collected in the bag air filter, protecting the exhaust fan behind the air duct and avoiding the hassle of manual cleaning.
[0015] Thirdly, by setting up a spray component, this utility model reduces the temperature of aluminum-magnesium dust during the cutting of aluminum-magnesium alloy profiles, thereby reducing the possibility of aluminum-magnesium dust explosion. At the same time, because the water mist adheres to the surface of the aluminum-magnesium dust, this increases the particle size of the aluminum-magnesium dust and reduces the difficulty of collection.

[0021] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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 protection scope of the present invention.
[0022] This utility model provides a wet dust removal device for aluminum-magnesium alloy cutting dust. The solution of this utility model is as follows:
[0023] like Figures 1-2 As shown, a wet explosion-proof dust removal device for cutting aluminum-magnesium alloy includes a workbench 1, a cutting blade 2 mounted on the workbench, an air duct 3 mounted above the cutting blade 2, a bag air filter 7 mounted on the air duct 3, an exhaust fan 8 mounted on the air duct 3 after the bag air filter 7, and an air duct opening 31 near the cutting blade on the air duct 3. A sprayer assembly is installed at the air duct opening 31. When aluminum-magnesium alloy is cut by a high-speed rotating blade, it will generate high-temperature dust. The sprayer assembly can spray water mist to reduce the temperature of the aluminum-magnesium dust and adhere to the dust surface, increasing the dust particle size, reducing the difficulty of collection, facilitating filtration and collection by the bag air filter 7, and preventing the aluminum-magnesium dust from spreading in the production workshop.
[0024] The spray assembly includes a spray nozzle 41 installed at the air duct opening 31. The spray nozzle 41 includes a fixed end 411 and a spray head 412. One end of the fixed end 411 is threadedly connected to the spray head 412, and the other end of the fixed end 411 is fixedly connected to the spray pipe 42. A through hole is opened in the air duct opening 411, and the spray nozzle 41 is fixedly connected to the through hole of the air duct opening 31 at the fixed end 411. The other end of the spray pipe 42 extends to the bottom of the water tank 43. The water tank 43 is also connected to a compressed air pipe 44, and the other end of the compressed air pipe 44 is connected to a compressed air source 46. Compressed air is introduced into the water tank 43 through the compressed air pipe 44, forming a large air pressure inside the water tank 43. The high air pressure forces the water in the water tank to pass through the spray pipe 42 and the spray nozzle 41 in sequence to form a water vapor spray.
[0025] The upper part of the water tank 43 also has a water tank cover 45 that matches the water tank. It can seal the upper part of the water tank, which makes it easier to form a large air pressure inside the water tank 43. The air pressure causes the water in the water tank 43 to form water vapor spray through the spray pipe 42 and the spray nozzle 41.
[0026] Furthermore, the spray nozzle 41 can adjust the amount of spray as needed by rotating the spray head 412 to adapt to different aluminum-magnesium alloy cutting conditions.
[0027] Furthermore, a water level gauge 47 made of transparent material is sealed and fixedly connected to the upper and lower sides of the water tank 43. The water level gauge 47 has a scale, which allows the water level in the water tank to be known from the outside, making it convenient to add water in time when it is low.
[0028] The specific working method is as follows: When the cutting tool 2 is cutting the aluminum-magnesium alloy profile, the exhaust fan 8 is turned on, thereby creating a negative pressure at the air outlet 31. The air near the air outlet 31 carries the suspended aluminum-magnesium dust into the air outlet 31 and enters the bag air filter 7 along the air duct 3. The compressed air source 46 is turned on, and compressed air is introduced into the water tank through the compressed air pipe 44. The internal pressure of the water tank 43 increases, so the water in the water tank 43 enters the spray nozzle 41 through the spray pipe 42. The water mist is then sprayed from the spray nozzle 41 onto the working area of the cutting tool 2. Depending on the aluminum-magnesium alloy to be cut, the spray head 412 is adjusted so that the water mist can completely cover the area where aluminum-magnesium dust splashes, ensuring that the water mist adheres to the aluminum-magnesium dust and reduces the temperature of the aluminum-magnesium dust. Moreover, the aluminum-magnesium dust will carry the water mist and enter the bag air filter 7 with the direction of airflow, thereby avoiding the explosion accident caused by the spillage of aluminum-magnesium dust in the workshop.
[0029] When the bag air filter 7 has collected a certain amount of aluminum-magnesium dust and needs to be replaced, loosen the bolts securing the bag air filter. Since the bag air filter 7 is already filled with some aluminum-magnesium alloy cutting dust, it is not easy to remove it from the air duct. At this time, compress the expansion joint 6 to open a larger gap in the air duct 3, making it easier to remove the bag air filter 7 containing aluminum-magnesium cutting dust. At the same time, replace it with a new bag air filter 7. The collected aluminum-magnesium dust is properly disposed of directly in the used bag air filter 7 to prevent aluminum-magnesium dust from spilling into the workshop.
[0030] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
