Description

Technical Field

[0001] This utility model relates to the field of dust removal technology for aluminum and magnesium dust, specifically to a multi-stage filtration explosion-proof wet dust removal device for aluminum and magnesium dust. Background Technology

[0002] With the increasingly widespread application of aluminum-magnesium alloys in industries such as aerospace, automobile manufacturing, and electronic equipment, the processing scale of aluminum-magnesium products is constantly expanding. During the processing and production of aluminum-magnesium products, a large amount of aluminum-magnesium dust is generated. Aluminum-magnesium dust is flammable and explosive. Once it reaches a certain concentration in the air, it can easily cause an explosion when it comes into contact with a source of ignition, seriously threatening production safety and the lives and health of personnel. Traditional dry dust removal methods pose significant safety hazards in the treatment of aluminum-magnesium dust. In contrast, wet dust removal technology is increasingly widely used in the field of aluminum-magnesium dust control because it can effectively reduce the risk of dust explosion.

[0003] However, traditional wet dust collectors are not very efficient at reducing and removing dust from the air mixed with aluminum and magnesium dust. Although they can collect dust to a certain extent, they cannot solve the risk of dust explosion. When the equipment discharges air that has been completely dust-reduced, the dust accumulated inside the production plant can be ignited, which can cause a more serious secondary explosion and pose a serious safety hazard. Therefore, we have proposed a multi-stage filtration explosion-proof wet dust collector for aluminum and magnesium dust. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6A multi-stage filtration explosion-proof wet scrubbing device for aluminum and magnesium dust includes a wet scrubbing body 1, a fan 2, a circulating spray device 3, a baffle 5, and a filter element 6. The circulating spray device 3 is located at the top of the wet scrubbing body 1, and is connected to the four corners of the top of the wet scrubbing body 1 by matching screws. The circulating spray device 3 and the interior of the wet scrubbing body 1 form a cavity. The fan 2 is located on the side wall of the wet scrubbing body 1, and the fan 2 is connected to the wet scrubbing body. The wet dust collector body 1 is internally connected, and a baffle 5 is provided at the top of the body. The baffle 5 is slidably connected to the inner wall of the wet dust collector body 1. A filter element 6 is provided at the bottom of the baffle 5 inside the wet dust collector body 1. After the device is fixed in the designated location, a clean water solution is injected into the wet dust collector body 1. The solution inside the wet dust collector body 1 will submerge the filter element 6 and the bottom of the baffle 5. Then the device is started to remove aluminum and magnesium dust mixed air inside the production plant.

[0026] Furthermore, the partition 5 is a rectangular plate, and two sets of six partitions 5 are arranged in a cross-staggered manner on the two opposite side walls inside the wet dust collector body 1. The pointed ends of the six partitions 5 correspond to one side of the fan 2. After the aluminum-magnesium dust mixed air is drawn into the inner cavity of the wet dust collector body 1 by the fan 2, the cross-staggered distribution structure of the six partitions 5 makes the internal airflow path bend, and the space between two adjacent partitions 5 makes it very easy for the drawn aluminum-magnesium dust mixed air to swirl. Therefore, while ensuring a fast enough suction rate, the residence time of the aluminum-magnesium dust mixed air inside the wet dust collector body 1 is increased, which facilitates the circulating spray device 3 to spray the swirling aluminum-magnesium dust mixed air inside for dust removal, thereby improving the dust removal quality and efficiency.

[0027] Furthermore, the side wall of the wet scrubber body 1 facing away from the fan 2 is provided with an exhaust port 9, and the side of the fan 2 facing away from the wet scrubber body 1 is provided with a hollow open dust suction hood 14 with a horizontal boss structure. The side wall of the wet scrubber body 1 is provided with a water pump 10, and the top end of the water pump 10 is provided with a connecting flange pipe. The top end of the wet scrubber body 1 is provided with a connection hole 8 at each of the four corners. The fan 2 draws the aluminum and magnesium dust mixed with air inside the production plant into the wet scrubber body 1 through the dust suction hood 14, and then discharges it through the exhaust port 9 after the dust removal work.

[0028] Furthermore, the wet dust collector body 1 has two sets of equally spaced mounting grooves 11 on its two opposite side walls, and the two sets of mounting grooves 11 are staggered and crisscrossed. The mounting grooves 11 are inclined at a 45-degree angle. A support ring 12 is welded to the bottom of the mounting groove 11 inside the wet dust collector body 1. The support ring 12 has connection holes 13 at each of its four corners. The water pump 10 is positioned horizontally below the support ring 12. The bottom of the wet dust collector body 1 has a funnel-shaped structure, and a liquid discharge valve 4 is provided at the center of the bottom end of the wet dust collector body 1. The mounting grooves 11 facilitate the installation or replacement of the partition 5, improving maintenance efficiency.

[0029] Furthermore, the circulating spray device 3 has connection holes 15 at each of its four corners. The connection holes 15 are connected to the connection holes 8 by matching screws. The top of the circulating spray device 3 is equipped with a liquid distribution module 16. The side wall of the liquid distribution module 16 is equipped with a liquid delivery pipe 17. The bottom end of the liquid delivery pipe 17 is connected to the top flange of the water pump 10. The bottom of the circulating spray device 3 is equipped with two sets of eight atomizing spray heads 7 arranged in a cross-staggered manner. A partition 5 is placed between two adjacent atomizing spray heads 7. The top of the space between two adjacent partitions 5 is the atomizing spray head 7. The atomizing spray head 7 can spray and remove dust from the swirling aluminum and magnesium dust mixed with air. After being wetted, the aluminum and magnesium dust will flow into the solution inside the wet scrubber body 1 along the side wall of the partition 5. The filtered solution is pumped to the top of the circulating spray device 3 by the water pump 10 to continue the spray dust removal work.

[0030] Furthermore, the filter element 6 is a hollow rectangular box with an open top, and each of the four outer corners of the top of the filter element 6 has a connection hole 18. The connection hole 18 is connected to the connection hole 13 by an adapter bolt. The filter element 6 has a filter screen 19 at the bottom inside. The filter screen 19 can filter larger aluminum and magnesium dust particles to prevent damage and blockage to the water pump 10 and the circulating spray device 3.

[0051] Working Principle: Following the diagram, the multi-stage filtration explosion-proof wet scrubber for aluminum and magnesium dust is correctly installed in the aluminum and magnesium product processing plant. Upon activation, the fan 2 generates negative pressure through the dust collection hood 14, rapidly drawing the aluminum and magnesium dust mixture into the wet scrubber body 1. The dust collection hood 14 on the side of the fan 2 facing away from the wet scrubber body 1 has a hollow opening with a horizontal boss structure, allowing for better dust collection. After entering the wet scrubber body 1, due to… The interior is equipped with two sets of six partitions 5 arranged in a staggered pattern. This causes the airflow path of the aluminum-magnesium dust mixture to become tortuous, and the narrow space between adjacent partitions 5 makes air easily swirling. This significantly prolongs the airflow's residence time within the main body 1. Simultaneously, the circulating spray device 3 begins operation. The liquid distribution module 16 at the top of the circulating spray device 3 is connected to the water pump 10 via a liquid delivery pipe 17. The water pump 10 draws the solution, after sedimentation and filtration at the bottom of the wet scrubber main body 1, to the liquid distribution module 16, and then... The liquid distribution module 16 distributes the solution to the eight atomizing spray heads 7 arranged in a staggered pattern at the bottom of the circulating spray device 3. The atomizing spray heads 7 atomize the solution into fine water droplets, providing all-round and efficient spraying of the swirling aluminum-magnesium dust mixed with air. After being adsorbed and moistened by the water droplets, the aluminum-magnesium dust falls along the side wall of the partition 5 into the solution at the bottom of the wet scrubber body 1. The funnel-shaped structure of the bottom of the wet scrubber body 1 facilitates dust sedimentation. The settled dust and waste can be periodically discharged through the liquid discharge sludge valve 4 at the center of the bottom end. The slag and the solution need to be filtered through filter element 6. Filter element 6 is a hollow rectangular box with an open top. The filter screen 19 at the bottom of the inside can intercept larger aluminum and magnesium dust particles to prevent them from entering the water pump 10 and the circulating spray device 3, causing damage and blockage. The filtered solution is pumped back to the top of the circulating spray device 3 by the water pump 10 and continuously circulates for spray dust removal. Finally, the fully dust-removed air is discharged from the exhaust port 9 on the side wall of the wet dust collector body 1 away from the fan 2, completing the entire dust removal process.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
