In many industrial production processes, especially in the coal, metal, fertilizer and pharmaceutical industries, the generation of explosive dust often brings safety hazards and affects the environment and equipment. For example, in the process of polishing metal workpieces such as aluminum-magnesium alloy, a large amount of flammable dust is generated, which not only pollutes the environment, but also poses a serious safety hazard. In the prior art, the problems of preventing the leakage and accumulation of explosive dust and achieving efficient dust cleaning have not been effectively solved.

[0003] Currently, the management of explosive dust mainly relies on various types of spray towers, dust removal equipment and airflow treatment technology.

[0015] The application also provides a dust removal method of the pneumatic cyclone tower for explosive aluminum-magnesium dust treatment. S1. The gas containing explosive dust is introduced into the inner part of the spray tower through the air inlet pipe; S2. The water is transported from the water outlet tank to the water sprayer through the water pump, and the water droplets are sprayed into the inner part of the spray tower from the water sprayer, so that the water droplets collide with and fuse with the dust particles; S3. The motor is started to drive the rotating rod to rotate, and the rotating rod drives the long rod to rotate through the belt transmission mechanism; S4. When the long rod rotates, the windmill blades at the top rotate, cooperate with the water droplets sprayed by the water sprayer to form a spiral rotating air flow, and promote the dust to fuse with the water droplets and be thrown to the inner wall of the spray tower; S5. The long rod synchronously drives the scraper to slide on the inner wall of the spray tower, and scrapes off the dust mud adhered to the inner wall; S6. Before the gas containing explosive dust enters the spray tower, the gas is firstly filtered through the filter screen one in the air inlet pipe; S7.

[0016] Compared with the prior art, the application has the following beneficial effects: 1、The present application drives the rotating rod by motor, drives the long rod to rotate through the belt, and the windmill blades at the top of the long rod rotate synchronously, which cooperates with the water sprayer below the blades to form a spiral rotating airflow in the spray tower. The airflow can forcibly push the dust particles and spray droplets to collide, intercept and fuse, greatly improving the dust capture efficiency, especially solving the problem of capturing small particles in traditional equipment. At the same time, the long rod rotates synchronously to drive the fixed scraper on the outer surface to slide in the inner wall of the spray tower, which can scrape off the attached dust and mud in real time, avoiding the accumulation of dust on the tower wall, which reduces the efficiency of the equipment. Compared with the traditional spray tower, the present application can realize continuous operation of dust treatment, significantly improve the treatment efficiency, reduce the labor input, avoid the safety hidden danger caused by dust accumulation and the interference to the production process.

[0017] 2、The present application sets filter screen one in the inlet pipe, sets filter screen two in the outlet pipe, and sets filter plate at the bottom of the spray tower to build a "three-stage filtration" system: the dust-containing gas is first intercepted by filter screen one, then the "dust-liquid droplet" fusion is separated by filter plate, and finally the residual fine dust is intercepted by filter screen two. Among them, filter screen one is fixed by screw rod and clamping hole, and the stop block limits it. When disassembling, only need to rotate the screw rod to quickly take out the filter screen one for cleaning or replacement. Compared with the traditional equipment, the present application realizes the modularization of the filter structure, which not only can adapt to the filtering needs of aluminum and magnesium dust of different particle sizes, ensures that the discharged gas meets the standard, but also makes the storage, cleaning and replacement of the filter screen more convenient.

[0018] 3、The present application realizes the integration of motor, rotating rod, belt and long rod, which efficiently transmits the power of motor to the windmill blades and scraper, reduces the energy loss caused by multi-component transmission; at the same time, the wastewater after spraying flows into the wastewater box through the filter plate, and then is transported back to the water outlet tank through the water return pipeline with filter device and water return pump, and is transported back to the water sprayer by the water pump for recycling. This design combines power transmission and water resource utilization, and distributes the equipment operation energy consumption and water resource consumption to the whole dust removal process, so that the system is more uniform in stress, reduces the load of single component, avoids the problem of high operation cost caused by large power loss and one-time use of water resources in traditional equipment, and prolongs the service life of the core components of the equipment.

[0019] 4. In this invention, the scraper is fixedly connected to the long rod and rotates synchronously with the rod to achieve automatic dust scraping. Its design, which tightly adheres to the tower wall, significantly increases the thoroughness of dust scraping and prevents dust residue. Simultaneously, the scraper is made of wear-resistant material, which reduces wear during the dust scraping process and improves the stability of equipment operation. Furthermore, the filter plate is slidably connected to the inner wall of the spray tower and can be directly pulled out for cleaning without disassembling the tower body; the detachable design of the filter screen also reduces the difficulty of maintenance. Compared to the difficulties of manual dust cleaning and the easy wear of parts in traditional equipment, this technology, through the automatic dust scraping and wear-resistant design of the scraper, not only improves the stability of the construction (dust removal) process but also makes equipment maintenance more convenient, reduces the safety risks of manual maintenance, and enhances the continuity and reliability of the overall dust removal operation.

[0020] 5. This invention ensures the safety and practicality of dust removal operations from multiple perspectives: the automatic dust scraper avoids the safety hazards of manual entry into the tower for dust removal; the three-stage filtration system ensures no leakage of aluminum and magnesium dust, reducing the risk of explosion; the integrated transmission and water circulation design achieves low energy consumption and resource recycling without increasing equipment costs or operational difficulty; the detachable filter screen and slidingly connected filter plate allow ordinary operators to complete maintenance without professional skills. This technology, while ensuring safety and practicality, does not increase equipment investment or operational barriers, effectively solving the problems of high safety hazards and complex operation of traditional dust control equipment.

[0021] 6. The pneumatic cyclone tower of this invention has a simple overall structure. Core components such as the motor, scraper, and filter are all conventional industrial parts, requiring no special customization and resulting in low cost. The equipment operation process is clear, and ordinary workers can operate it after simple training. All accessories can be disassembled after construction and carried to the next work site for reuse, requiring no special maintenance. Compared with existing explosive dust control equipment, which suffers from complex structure, high cost, difficult maintenance, and difficulty in reusing parts, this invention offers extremely high cost-effectiveness, solving the pain points of equipment promotion and application in the industry. It is very suitable for widespread promotion in industrial fields that generate explosive dust, such as aluminum-magnesium alloy processing and metal grinding.

[0022] 7. This invention relates to a pneumatic cyclone tower dust removal method for the control of explosive aluminum-magnesium dust. Through "graded filtration + precise coordination of airflow and spraying," it achieves efficient capture and compliant emission of aluminum-magnesium dust of different particle sizes. Relying on "real-time simultaneous dust cleaning and removal," it ensures continuous and stable operation and reduces the safety risks of manual dust cleaning. The "standardized water circulation process" reduces water consumption and operating costs. "Integrated transmission" achieves low-energy operation and simplifies operation. Combined with a "convenient filter maintenance process," it reduces equipment maintenance difficulty and downtime. The entire system requires no additional equipment investment or operational barriers. It comprehensively solves the problems of fragmented filtration, disconnect between cleaning and removal, resource waste, high energy consumption, and difficult maintenance inherent in traditional dust removal methods. It significantly improves dust control efficiency, safety, and economy, and is suitable for dust control needs in continuous production scenarios such as aluminum-magnesium alloy processing.

Detailed Implementation

[0029] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Please see Figures 1 to 5This invention provides an aerodynamic cyclone tower for the treatment of explosive aluminum-magnesium dust, comprising: a base 101; a spray tower 104, fixedly installed on the top of the base 101, with a long rod 113 rotatably connected to the inner wall of the center of the spray tower 104; a windmill blade 114, fixedly installed on the top of the long rod 113, with a water sprayer 117 fixedly installed on the inner wall of the spray tower 104, the water sprayer 117 being located directly below the windmill blade 114; a motor 110, fixedly installed on one side of the spray tower 104, with a rotating rod 111 fixedly installed at the output end of the motor 110, and a belt 112 movably sleeved on the bottom end of the rotating rod 111 via a pulley, one end of the belt 112 being... A scraper 120 for scraping dust and sludge is fixedly installed on the outer surface of the long rod 113, which is movably sleeved at the bottom end of the long rod 113 via a pulley. The scraper 120 is in close contact with the inner wall of the spray tower 104 to scrape off the dust and sludge adhering to the inner wall. The motor 110 drives the rotating rod 111 to rotate, and the rotating rod 111 drives the belt 112 to rotate via the pulley. At this time, the belt 112 drives the long rod 113 to rotate via the pulley. The long rod 113 drives the fan blades 114 to rotate. The rotation of the fan blades 114 cooperates with the water sprayer 117 to make the dust inside rotate in a spiral. After rotation, some of the dust and water are mixed and thrown to the inner wall of the spray tower 104. Specifically, the long rod 113 is set along the central axis of the spray tower 104. Its top end is rotatably mounted on the top wall of the spray tower 104 via a top bearing, and its bottom end is rotatably mounted on the center of the bottom plate of the spray tower 104 via a bottom bearing seat.

[0031] A filter plate 103 is slidably connected to the inner wall of the spray tower 104 near its bottom. A wastewater box 102 is fixedly installed on the top of the base 101. The sprayed droplets collide with the dust entering the spray tower 104, intercepting and merging the dust. At this time, the dust falls into the interior of the filter plate 103 under the action of gravity. Specifically, the bottom of the wastewater box 102 is connected to the outlet tank 115 through a return water pipe, and the pipe is equipped with a filter device and a return water pump (not shown) to transport the filtered wastewater back to the outlet tank 115, realizing the recycling of water.

[0032] Wastewater box 102 is located directly below filter plate 103. A water outlet tank 115 is fixedly installed on the side of base 101 near its top. A water pump 116 is fixedly installed on one side of spray tower 104. The water pump 116 is connected to the water outlet tank 115 through a pipe. The output end of the water pump 116 is connected to the inside of sprayer 117 through a pipe. An air outlet pipe 118 is fixedly installed on the top of spray tower 104. Explosive dust first enters the inside of spray tower 104 through air inlet pipe 105. The larger dust particles are filtered for the first time by the filter screen 108. After filtration, the dust enters the inside of spray tower 104. The water pump 116 is started by external power to collect the water inside the water outlet tank 115 through the pipe and deliver it to the inside of sprayer 117 through the output pipe. The sprayed droplets collide with the dust entering the inside of spray tower 104 and intercept and merge the dust.

[0033] A second filter screen 119 is fixedly installed inside the air outlet pipe 118. An air inlet pipe 105 is fixedly installed on one side of the spray tower 104. Two blocks 107 are fixedly installed on the inner wall of the air inlet pipe 105 to limit the first filter screen 108. Two threaded rods (106) are threadedly connected to the inner wall of the air inlet pipe (105). The ends of the threaded rods (106) are movably embedded in the locking holes (109) of the first filter screen (108). When disassembling the first filter screen 108, it is only necessary to rotate the threaded rods 106 to move them inside the air inlet pipe 105. At this time, the threaded rods 106 are disengaged from the inside of the locking holes 109, and the first filter screen 108 can be disengaged from one side of the block 107. The block 107 is used to limit the first filter screen 108 so that the locking holes 109 are always on the side parallel to the threaded rods 106, which is convenient for installation. In one specific embodiment, the outlet of the air inlet pipe 105 is tangentially connected to the inner wall of the spray tower 104. After the dust-laden airflow enters the tower, it forms a rotating airflow. The rotation of the wind turbine blades 114 at the top of the tower can further enhance and stabilize the rotating airflow, so that the dust inside is efficiently separated under the action of centrifugal force.

[0034] Both sides of the filter screen 108 are provided with locking holes 109, and two threaded rods 106 are movably embedded in the two locking holes 109. The threaded rods 106 are movably embedded in the filter screen 108 to limit the position of the filter screen 108.

[0035] When using the pneumatic cyclone tower for controlling explosive aluminum-magnesium dust, step S1 is first executed, introducing gas containing explosive dust into the spray tower 104 through the inlet pipe 105. Then, in step S6, before entering the spray tower 104, the gas undergoes initial filtration through a filter screen 108 inside the inlet pipe 105. The filter screen 108 is fixed to the inner wall of the inlet pipe 105 by a threaded rod 106 and a baffle 107, effectively removing larger dust particles from the gas. Next, the water pump 116 is started, executing step S2, to deliver water from the outlet tank 115 through a pipe to the water sprayer 117. The water sprayer 117 is located directly below the wind turbine blades 114, spraying droplets into the spray tower 104. The droplets collide with and intercept the dust particles, causing them to merge.

[0036] Next, step S3 is executed, starting the motor 110 on one side of the spray tower 104. The output end of the motor 110 drives the rotating rod 111 to rotate. The bottom end of the rotating rod 111 is connected to the belt 112 via a pulley, and the other end of the belt 112 drives the long rod 113 to rotate via a pulley. The windmill blade 114 fixed at the top of the long rod 113 rotates synchronously with the long rod 113 (step S4). The rotation of the windmill blade 114, in conjunction with the droplets sprayed by the water sprayer 117, forms a spiral airflow inside the spray tower 104, causing the dust and droplets to fully mix and be thrown towards the inner wall of the spray tower 104 by centrifugal force. At the same time, the scraper 120 fixed on the outer surface of the long rod 113 slides on the inner wall of the spray tower 104 (step S5), scraping off the dust and mud adhering to the inner wall.

[0037] The fused dust falls under gravity onto the filter plate 103 at the bottom of the spray tower 104 (step S7). The filter plate 103 is slidably connected to the inner wall of the spray tower 104, and a wastewater box 102 is installed below it. The filtered wastewater enters the wastewater box 102 through the small holes at the bottom of the filter plate 103 for collection. Then, in step S8, the water in the wastewater box 102 is transported back to the outlet tank 115 through the return water pipeline (including the filter device and the return water pump), realizing water recycling. Finally, the purified gas is discharged through the gas outlet pipe 118 at the top of the spray tower 104. The filter screen 119 inside the gas outlet pipe 118 performs secondary filtration on the gas (step S9) to ensure that the residual particulate matter in the discharged gas meets the standards.

[0038] Working principle: During operation, explosive aluminum-magnesium dust first enters the spray tower 104 through the inlet pipe 105. Larger dust particles are initially filtered by the filter screen 108. After filtration, the dust enters the spray tower 104. An external power source activates the water pump 116, which collects water from the outlet tank 115 through a pipe. This water is then delivered to the sprayer 117 via the output pipe. The sprayed droplets collide with the dust entering the spray tower 104, intercepting and agglomerating it. The dust then falls into the filter plate 103 under gravity. The motor 110 then drives the rotating rod 111 to rotate, which in turn drives the belt 112 via a pulley. 112 drives the long rod 113 to rotate via the pulley. At this time, the long rod 113 drives the windmill blades 114 to rotate. The rotation of the windmill blades 114, in conjunction with the water sprayer 117, causes the dust inside to rotate in a spiral. After rotation, some of the dust and water are mixed and thrown to the inner wall of the spray tower 104. When the long rod 113 rotates and drives the scraper 120 to rotate on the inner wall of the spray tower 104, it can scrape the dust and mud adhering to its inner wall to the inside of the filter plate 103. The water enters the wastewater box 102 through the small holes at the bottom of the filter plate 103 for collection. The rotation of the windmill blades 114 promotes the upward flow of air, which allows the gas inside the dust to enter the inside of the exhaust pipe 118. The particulate matter inside the gas is intercepted by the filter screen 119. When disassembling filter screen 108, simply rotate threaded rod 106 to move it inside intake pipe 105. At this time, threaded rod 106 disengages from inside locking hole 109, allowing filter screen 108 to disengage from one side of stop block 107. Stop block 107 is used to limit filter screen 108, ensuring that locking hole 109 is always on the side parallel to threaded rod 106, facilitating installation.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
