Description

Technical Field

[0001] This utility model belongs to the field of metal processing technology, and in particular relates to a high-efficiency and energy-saving dust removal device for recycled aluminum melting and casting. Background Technology

[0002] According to the published patent CN222427527U, a high-efficiency dust removal device for a recycled aluminum smelting and casting workshop is described. A side shell is fixedly connected to the side wall of the housing, and an exhaust pipe is fixedly passed through the side shell. The end of the exhaust pipe away from the smelting and casting workshop extends into the upper half of the housing. A filter screen is fixedly connected to the lower half of the housing, and a partition is fixedly connected between the filter screen and the top wall of the housing. A dust-collecting section is provided on the side of the partition near the exhaust pipe, and a cyclone gas-liquid separator is provided on the side of the partition away from the exhaust pipe. This achieves gas-liquid separation by the upward movement of gas and entrained reagents into the cyclone gas-liquid separator. The reagents are discharged from the drain end of the cyclone gas-liquid separator and fall into the lower half of the housing, thus recovering the reagents and reducing waste. However, the following shortcomings still exist:

[0003] After completion, the above equipment simply removes dust from the gas by spraying chemicals. However, because the contact time between the gas and the chemicals is short, some dust will still not be removed by the liquid after spraying, resulting in poor dust removal effect. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency and energy-saving dust removal device for recycled aluminum casting. Through the cleaning mechanism and the spraying mechanism, it solves the problem that due to the short contact time between the gas and the agent, some dust still cannot be removed by the liquid after the agent is sprayed, resulting in poor dust removal effect.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a high-efficiency and energy-saving dust removal device for recycled aluminum melting and casting, including a processing box. An air inlet pipe is fixedly connected to the outer wall of the processing box, and an axial flow fan is fixedly connected to the inner wall of the air inlet pipe on the side away from the processing box.

[0007] The inner wall of the processing box is equipped with a cleaning mechanism, which includes a protective box. The outer wall of the protective box is fixedly connected to the outer wall of the processing box. A motor is fixedly connected to the inner wall of the protective box. The output end of the motor is fixedly connected to a connecting shaft via a coupling. A pulley is rotatably connected to the outer wall of the connecting shaft. A belt is driven through the inner wall of the pulley. A second pulley is driven through the outer wall of the belt away from the pulley. Positioning rods are fixedly connected to the outer walls of both the pulley and the second pulley. A connecting plate is fixedly connected to the outer wall of the positioning rod near the protective box.

[0008] Furthermore, a push rod is rotatably connected to the outer wall of the connecting plate, and a connecting rod is rotatably connected to the outer wall of the push rod away from the connecting plate. The outer wall of the connecting rod is slidably connected to the inner wall of the processing box. A scraper is rotatably connected to the outer wall of the connecting rod away from the push rod. A filter plate is slidably connected to the outer wall of the scraper. The outer wall of the filter plate is fixedly connected to the inner wall of the processing box. A grid plate is fixedly connected to the top outer wall of the processing box. A spraying mechanism is provided on the inner wall of the processing box.

[0009] Furthermore, the spraying mechanism includes a guide plate, the outer wall of which is fixedly connected to the inner wall of the processing box, a positioning shaft is rotatably connected to the inner wall of the processing box near the guide plate, a plurality of impellers are fixedly connected to the outer wall of the positioning shaft, and a plurality of baffles are rotatably connected to the outer wall of the positioning shaft, the outer wall of which is fixedly connected to the inner wall of the processing box.

[0010] Furthermore, a gear is fixedly connected to the outer wall of the positioning shaft near the water baffle plate, and several second gears mesh with the outer wall of the gear, and a filter cylinder is fixedly connected to the outer wall of the several second gears.

[0011] Furthermore, a second scraper is slidably connected to the inner wall of the filter cylinder, and a second connecting rod is fixedly connected to the outer wall of the second scraper on the side away from the filter cylinder. The outer wall of the second connecting rod is fixedly connected to the outer wall of the baffle plate.

[0012] Furthermore, the inner wall of the processing box is provided with several drainage outlets, and the outer wall of the processing box is fixedly connected with several water storage boxes.

[0013] Furthermore, several water pumps are fixedly connected to the bottom of the inner wall of the water storage box, and water pipes are fixedly connected to the output end of the water pumps. A diversion pipe is fixedly connected to the outer wall of the end of the water pipe away from the water pump.

[0014] Furthermore, the outer wall of the diversion pipe is fixedly connected to the outer wall of the water storage box, and a number of nozzles are fixedly connected to the outer wall of the diversion pipe. The outer wall of the nozzles is fixedly connected to the inner wall of the processing box.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a filter plate and a grid plate. The gas sprayed with liquid rises and comes into contact with the two filter plates, which then perform secondary filtration of dust in the gas. The filtered gas is then discharged through the grid plate on top of the processing box. By placing the two filter plates in front of the exhaust port, the gas to be discharged is subjected to secondary filtration, preventing the problem that some dust cannot be removed by the liquid after spraying due to the short contact time between the gas and the agent, thus avoiding poor dust removal effect.

[0017] 2. This utility model incorporates a filter cylinder and a second scraper. A second gear drives the filter cylinder to rotate, and the second connecting rod inside the filter cylinder is connected to a baffle plate, thus not rotating with the filter cylinder. A second scraper is installed on the outside of the second connecting rod, and the outer side of the second scraper contacts the inner wall of the filter cylinder. Therefore, the second scraper scrapes away impurities adhering to the inner wall of the second connecting rod, collecting them inside the filter cylinder. The liquid is then discharged into water storage boxes on both sides of the device through drain outlets on both sides. This achieves the goal of filtering out impurities from the liquid through the rotation of the filter cylinder and scraping impurities from inside the filter cylinder into its interior through the second scraper. This prevents the problem of reduced device efficiency caused by the limited liquid storage capacity, which necessitates stopping the device for replenishment and drainage after the liquid is exhausted before continued use.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is a high-efficiency and energy-saving dust removal device for recycled aluminum melting and casting, including a processing box 1. An air inlet pipe 101 is fixedly connected to the outer wall of the processing box 1. An axial flow fan 102 is fixedly connected to the inner wall of the side of the air inlet pipe 101 away from the processing box 1. The axial flow fan 102 is used to draw outside air into the interior of the processing box 1 through the air inlet pipe 101.

[0029] A cleaning mechanism 2 is provided on the inner wall of the processing box 1. The cleaning mechanism 2 includes a protective box 201. The outer wall of the protective box 201 is fixedly connected to the outer wall of the processing box 1. A motor 202 is fixedly connected to the inner wall of the protective box 201. The motor 202 is started. The output end of the motor 202 is fixedly connected to a connecting shaft 203 via a coupling. A pulley 204 is rotatably connected to the outer wall of the connecting shaft 203. A belt 205 is driven to the inner wall of the pulley 204. A second pulley 206 is driven to the outer wall of the end of the belt 205 away from the pulley 204. The two ends of the belt 205 simultaneously connect the pulley 204 and the second pulley 206, so that when the pulley 204 rotates, it drives the second pulley 206 to rotate simultaneously. Positioning rods 207 are fixedly connected to the outer walls of both the pulley 204 and the second pulley 206. A connecting plate 208 is fixedly connected to the outer wall of the positioning rod 207 near the protective box 201. The rotation of the positioning rod 207 drives the connecting plate 208 to rotate. 8. The connecting plate 208 is rotated, and a push rod 209 is rotatably connected to the outer wall of the connecting plate 208. A connecting rod 210 is rotatably connected to the outer wall of the end of the push rod 209 away from the connecting plate 208. Since the connection point between the push rod 209 and the connecting plate 208 is far from the center of the connecting plate 208, the rotation area of ​​the push rod 209 is larger than that of the connecting plate 208, allowing the push rod 209 to push the connecting rod 210 to move. The outer wall of the connecting rod 210 is slidably connected to the inner wall of the processing box 1, and the connecting rod 210 is away from the push rod. A scraper 211 is rotatably connected to one end of the outer wall of 209. A filter plate 212 is slidably connected to the outer wall of the scraper 211. The scraper 211 is pushed to slide along the outer wall of the filter plate 212 by the movement of the connecting rod 210, so as to scrape away the dust on the surface of the filter plate 212. The outer wall of the filter plate 212 is fixedly connected to the inner wall of the processing box 1. A grid plate 213 is fixedly connected to the top outer wall of the processing box 1. The grid plate 213 facilitates the exhaust of gas. A spraying mechanism 3 is provided on the inner wall of the processing box 1.

[0030] The spraying mechanism 3 includes a guide plate 301, the outer wall of which is fixedly connected to the inner wall of the processing box 1. The flow direction of the sprayed liquid is controlled by the guide plate 301. A positioning shaft 302 is rotatably connected to the inner wall of the processing box 1 near the guide plate 301. Several impellers 303 are fixedly connected to the outer wall of the positioning shaft 302. By arranging multiple impellers 303 below the two guide plates 301, the impellers 303 can be pushed to drive the positioning shaft 302 to rotate when the liquid flows. Several baffles 306 are rotatably connected to the outer wall of the positioning shaft 302. The outer wall of the baffles 306 is fixedly connected to the inner wall of the processing box 1. A gear 304 is fixedly connected to the outer wall of the end of the positioning shaft 302 near the baffles 306. Several second gears 305 mesh with the outer wall of the filter cylinder. The positioning shaft 302 drives the gear 304 to rotate. As the gear 304 meshes with the second gears 305, the gear 304 pushes the second gear 305 to rotate. The filter cylinder 307 is fixedly connected to the outer wall of the several second gears 305. The inner wall of the filter cylinder 307 is slidably connected to the second scraper 309. The outer wall of the second scraper 309 away from the filter cylinder 307 is fixedly connected to the second connecting rod 308. The outer wall of the second connecting rod 308 is fixedly connected to the outer wall of the baffle plate 306. As the filter cylinder 307 is driven to rotate by the second gears 305, the second scraper 309 inside the filter cylinder 307 will scrape off the impurities on the inner wall of the filter cylinder 307.

[0031] The inner wall of the processing box 1 has several drain outlets 310. Several water storage boxes 311 are fixedly connected to the outer wall of the processing box 1. Several water pumps 312 are fixedly connected to the bottom of the inner wall of the water storage box 311. The water pumps 312 spray the liquid inside the water storage box 311 at a uniform speed. The output end of the water pump 312 is fixedly connected to a water pipe 313. The outer wall of the end of the water pipe 313 away from the water pump 312 is fixedly connected to a diversion pipe 314. The liquid sucked out by the water pump 312 is divided into multiple parts through the diversion pipe 314. The outer wall of the diversion pipe 314 is fixedly connected to the outer wall of the water storage box 311. Several nozzles 315 are fixedly connected to the outer wall of the diversion pipe 314. The liquid is sprayed out through the nozzles 315. The outer wall of the nozzles 315 is fixedly connected to the inner wall of the processing box 1.

[0032] One specific application of this embodiment is:

[0033] When the equipment is needed, the device is moved to the desired location, and the axial flow fan 102 is started to draw outside air into the processing box 1 through the air inlet pipe 101. Then, the water pump 312 is started to draw liquid from the water storage box 311 and deliver it through the water pipe 313 into the distribution pipe 314, where it is divided into multiple portions. Finally, the liquid is sprayed out by the nozzle 315. When the liquid sprayed from the nozzle 315 comes into contact with the air, dust particles inside the air agglomerate and drip down with the liquid, contacting the guide plate 301. Because the surface of the guide plate 301 is tilted at a certain angle, the liquid converges into a water flow and flows below the guide plate 301. When the liquid flows to the outside of the guide plate 301, it pushes the guide plate 301 downwards. Multiple impellers 303 drive the positioning shaft 302 to rotate. The rotation of the positioning shaft 302 drives the gear 304 on the outside of the baffle plate 306 to rotate. Since the gear 304 meshes with multiple second gears 305, the gear 304 pushes the second gears 305 to rotate, which in turn drives the filter cylinder 307 to rotate. The second connecting rod 308 inside the filter cylinder 307 is connected to the baffle plate 306 and therefore does not rotate with the filter cylinder 307. At the same time, a second scraper 309 is installed on the outside of the second connecting rod 308, and the outside of the second scraper 309 contacts the inner wall of the filter cylinder 307. Therefore, the second scraper 309 scrapes away the impurities adhering to the inner wall of the second connecting rod 308 and collects them in the filter cylinder. Inside 307, liquid is then fed into water storage boxes 311 on both sides of the device through drain outlets 310 on both sides, thus maintaining liquid recycling. Gas sprayed with liquid then rises and contacts two filter plates 212, where dust is filtered a second time. The filtered gas is then discharged through the grid plate 213 on top of the processing box 1. During operation, the motor 202 can be started to rotate the connecting shaft 203, simultaneously rotating the pulley 204. Since the pulley 204 is connected to the belt 205, it can drive the belt 205 for transmission, causing the second pulley 206 at the other end of the belt 205 to rotate. Simultaneously, the pulley 204 and the second... Multiple identical positioning rods 207 are connected to the outer wall of each pulley 206. Therefore, the rotation of the pulley 204 and the second pulley 206 drives the two positioning rods 207 to rotate simultaneously, and the two positioning rods 207 drive the same connecting plate 208 to rotate. Since the part of the connecting plate 208 away from the center is connected to the push rod 209, when the connecting plate 208 drives the push rod 209 to rotate, the rotation area of ​​the push rod 209 is larger than that of the connecting plate 208. Therefore, the push rod 209 can push the connecting rod 210 to slide on the surface of the filter plate 212. At the same time, the movement range of the connecting rod 210 is limited by the processing box 1. Therefore, the connecting rod 210 can only push the scraper 211 horizontally back and forth to slide, thereby scraping away the dust on the surface of the filter plate 212.
