Description

Technical Field

[0001] This utility model relates to the field of aluminum ash slag recycling technology, specifically a dust-collecting aluminum ash slag screening shaking device. Background Technology

[0002] Aluminum ash slag, a major byproduct of the aluminum industry, is generated during the aluminum melting process, and its aluminum content accounts for approximately 1-12% of the total aluminum loss during production and use. Previously, aluminum ash slag was treated as waste and dumped, which not only wasted aluminum resources but also caused environmental problems. Therefore, finding economical and effective methods to utilize and manage aluminum ash slag will not only improve the economic efficiency of the aluminum industry but also achieve effective resource recycling.

[0003] Chinese Patent No. CN213377215U discloses a novel aluminum ash slag screening and processing equipment, relating to the field of aluminum ash slag recycling technology. The equipment includes a housing with a movable cover rotatably connected to its top. Both ends of the movable cover are fixedly connected to feed inlets. Inside the housing is a fixed frame with a screen fixedly connected to its inner bottom. Fixed shafts are fixedly connected to the middle of both sides of the fixed frame, rotatably connected to the housing. A motor is fixedly connected to the inside of the housing, with a rotating rod fixedly connected to the motor's output shaft. A movable rod is rotatably connected to one end of the fixed frame, with the end of the movable rod away from the fixed frame rotatably connected to the end of the rotating rod away from the motor. A discharge port is located in the middle of one side of the fixed frame. This patent solves the problems of low screening efficiency and difficulty in removing iron impurities in existing aluminum ash slag screening and processing equipment.

[0004] In actual use, the aluminum ash slag screening device of the above-mentioned patent has a poor working environment, and the aluminum ash slag material sticks to the screen and clumps, affecting the screening efficiency; therefore, it cannot meet the existing needs. In response, we have proposed a dust-collecting type shaking device for aluminum ash slag screening. Utility Model Content

[0005] The purpose of this utility model is to provide a dust-collecting type shaking device for aluminum ash slag screening, which solves the problem mentioned in the background art that the aluminum ash slag screening device is in poor working environment during actual use, and the aluminum ash slag material sticks to the screen and clumps, affecting the screening efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust-collecting type aluminum ash slag screening shaking device, including a device support, a shaking screening box installed on one side of the upper end of the device support, an eccentric frame installed on one side of the shaking screening box, and a movable frame installed between the eccentric frame and the shaking screening box. A top dust-collecting fan and a side dust-collecting fan are respectively installed on the upper end and side of the shaking screening box, and dust collection bags are installed inside both the top dust-collecting fan and the side dust-collecting fan.

[0007] Preferably, a support frame is welded to the outside of the device bracket, a guide frame is welded to the upper end of the support frame, and the lower end of the movable frame passes through the guide frame and is slidably connected to the guide frame.

[0008] Preferably, an electrical box is provided at the front end of the device bracket, and a servo motor is installed at the bottom of the device bracket. The servo motor, the top suction fan, and the side suction fan are electrically connected to the electrical box.

[0009] Preferably, the vibrating screening box and the movable frame are connected by fixing screws. A feed box is installed at one end of the vibrating screening box. A sealing plate is provided at the upper end of the feed box, and the sealing plate is fixedly connected to the feed box by a buckle. A maintenance plate is installed at the front end of the vibrating screening box, and the maintenance plate is fixedly connected to the vibrating screening box by a locking buckle.

[0010] Preferably, the bottom of the vibrating screening box is provided with an integrally formed guide plate, and a screening frame is installed at the bottom end of the guide plate. The surface of the screening frame is provided with integrally formed screening holes.

[0011] Preferably, an eccentric wheel is installed inside the eccentric frame, and a drive shaft runs through the inside of the eccentric wheel. One end of the drive shaft is fixedly connected to a drive wheel, and the servo motor is connected to the drive wheel via a pulley and a belt.

[0012] Preferably, the eccentric wheel and the interior of the eccentric frame are rotatably connected by bearings, and one end of the eccentric frame is hinged to the movable frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model's vibrating screening box features an eccentric frame. A servo motor drives an eccentric wheel to rotate inside the eccentric frame, causing the eccentric frame to move a movable frame. The movable frame, limited by a guide frame, reciprocates back and forth, thus moving the vibrating screening box. Increasing the servo motor's speed increases the vibration frequency of the screening box, resulting in high-frequency, small-amplitude vibration of the aluminum ash slag inside. This causes the aluminum ash slag to jump, tumble, and move forward on the screen surface. Fine particles and dust fall through the screening frame, while larger particles or clumps are discharged. For materials like aluminum ash slag that have a certain degree of agglomeration, the eccentric wheel's vibration trajectory is stable and controllable, with a fixed amplitude unaffected by load. This forceful vibration effectively solves the problems of material sticking to the screen and clumping, improving screening efficiency and aluminum recovery rate. It is also easy to install, maintain, and integrate into existing production lines.

[0015] 2. This utility model, by installing a top-mounted dust extraction fan and a side-mounted dust extraction fan on the outer shell of the shaking screening box, creates a negative pressure state inside the shaking screening box during screening. This generates a stable negative pressure airflow within the shaking screening box during the shaking process, instantly drawing away the dust generated during screening and sending it to a dust collection bag for collection. This approach maximizes dust control at the source, significantly improving collection efficiency and creating a clean working environment conducive to long-term operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] To address the issue of aluminum ash slag material sticking to the screen and clumping, affecting screening efficiency in existing aluminum ash slag screening devices during actual use, please refer to... Figure 1 - Figure 3 This embodiment provides the following technical solution:

[0023] The dust-collecting aluminum ash slag screening shaking device of this embodiment includes a device support 1. A shaking screening box 2 is installed on one side of the upper end of the device support 1. An eccentric frame 3 is installed on one side of the shaking screening box 2. A movable frame 303 is installed between the eccentric frame 3 and the shaking screening box 2. A support frame 102 is welded to the outside of the device support 1. A guide frame 306 is welded to the upper end of the support frame 102. The lower end of the movable frame 303 passes through the guide frame 306 and is slidably connected to the guide frame 306. By setting the eccentric frame 3, the servo motor 302 drives the eccentric wheel 304 to rotate inside the eccentric frame 3, so that the eccentric frame 3 drives the movable frame 303 to move. The movable frame 303 is limited by the guide frame 306 and moves back and forth, thereby driving the shaking screening box 2 to move.

[0024] The vibrating screening box 2 is connected to the movable frame 303 by fixing screws. A feed box 203 is installed at one end of the vibrating screening box 2. A sealing plate is provided at the upper end of the feed box 203, and the sealing plate is fixedly connected to the feed box 203 by a buckle. A maintenance plate 206 is installed at the front end of the vibrating screening box 2, and the maintenance plate 206 is fixedly connected to the vibrating screening box 2 by a locking buckle.

[0025] In addition, the bottom of the vibrating screening box 2 is provided with an integrally formed guide plate 205, and the bottom end of the guide plate 205 is equipped with a screening frame 204. The surface of the screening frame 204 is provided with integrally formed screening holes. Increasing the speed of the servo motor 302 can increase the vibration frequency of the vibrating screening box 2, thereby vibrating the aluminum ash slag inside the vibrating screening box 2 at a high frequency and with a small amplitude, causing the aluminum ash slag to jump, roll and move forward on the screen surface. Fine particles and dust fall through the screening frame 204, while larger particles or clumps are discharged through the inspection plate 206.

[0026] It should be noted that an eccentric wheel 304 is installed inside the eccentric frame 3, and a drive shaft 305 runs through the inside of the eccentric wheel 304. One end of the drive shaft 305 is fixedly connected to a drive wheel 301. The servo motor 302 is connected to the drive wheel 301 via a pulley and a belt. The eccentric wheel 304 is rotatably connected to the inside of the eccentric frame 3 via a bearing. One end of the eccentric frame 3 is hinged to the movable frame 303. The vibration trajectory of the eccentric wheel 304 is stable and controllable, and the amplitude is fixed and not affected by the load. The force vibration effectively solves the problems of material sticking to the screen and clumping, improves screening efficiency and aluminum recovery rate, and is easy to install, maintain and integrate into existing production lines.

[0027] Specifically, the vibrating screening box 2 is equipped with an eccentric frame 3. The servo motor 302 drives the eccentric wheel 304 to rotate inside the eccentric frame 3, which in turn drives the movable frame 303 to move. The movable frame 303 is limited by the guide frame 306 and moves back and forth, thereby driving the vibrating screening box 2 to move. Increasing the speed of the servo motor 302 can increase the vibration frequency of the vibrating screening box 2, thereby causing the aluminum ash slag inside the vibrating screening box 2 to vibrate at a high frequency and with a small amplitude. This causes the aluminum ash slag to jump, roll, and move forward on the screen surface. Fine particles and dust fall through the screening frame 204, while larger particles or clumps are discharged. For materials like aluminum ash slag that have a certain degree of clumping, the vibration trajectory of the eccentric wheel 304 is stable and controllable, and the amplitude is fixed and not affected by the load. The force vibration effectively solves the problem of material sticking to the screen and clumping, improves screening efficiency and aluminum recovery rate, and is easy to install, maintain, and integrate into existing production lines.

[0028] To address the issue of unfavorable working environments in the actual operation of existing aluminum ash slag screening devices, please refer to... Figure 1 - Figure 2 , Figure 4 This embodiment provides the following technical solution:

[0029] The top and side of the vibrating screening box 2 are respectively equipped with a top dust suction fan 201 and a side dust suction fan 202. Both the top dust suction fan 201 and the side dust suction fan 202 are equipped with dust collection bags. A stable negative pressure airflow is generated inside the vibrating screening box 2, which instantly draws away the dust generated during the screening process and sends it to the dust collection bags for collection. This can control the dust dispersion to the greatest extent from the source, greatly improve the collection efficiency, and create a clean working environment, which is conducive to long-term work.

[0030] The device support 1 has an electrical box 101 at its front end and a servo motor 302 installed below it. The servo motor 302, the top dust suction fan 201, and the side dust suction fan 202 are electrically connected to the electrical box 101. By installing the top dust suction fan 201 and the side dust suction fan 202 on the outer shell of the vibrating screening box 2, the inside of the vibrating screening box 2 is placed under a negative pressure state by first turning on the fans during the screening operation.

[0031] Specifically, by installing a top suction fan 201 and a side suction fan 202 on the outer shell of the shaking screening box 2, during the screening process, the fans are turned on first to create a negative pressure state inside the shaking screening box 2. This causes a stable negative pressure airflow to be generated inside the shaking screening box 2 during the shaking process, instantly drawing away the dust generated during the screening process and sending it to the dust collection bag for collection. This can control dust dispersion to the greatest extent from the source, greatly improve the collection efficiency, and create a clean working environment, which is conducive to long-term operation.

[0032] Working Principle: During use, a top suction fan 201 and a side suction fan 202 are installed on the outer shell of the vibrating screening box 2. During screening, the fans are turned on first to create a negative pressure inside the vibrating screening box 2. The vibrating screening box 2 is equipped with an eccentric frame 3. The servo motor 302 drives the eccentric wheel 304 to rotate inside the eccentric frame 3, causing the eccentric frame 3 to move the movable frame 303. The movable frame 303 is limited by the guide frame 306 and moves back and forth, thereby driving the vibrating screening box 2 to move. Increasing the speed of the servo motor 302 can improve the speed of the vibrating screening box. The shaking frequency of the 204 screen causes high-frequency, small-amplitude vibration of the aluminum ash slag inside the shaking screening box 2, making the aluminum ash slag jump, roll, and move forward on the screen surface. Fine particles and dust fall through the screening frame 204, while larger particles or clumps are discharged through the inspection plate 206. During the shaking process, a stable negative pressure airflow is generated inside the shaking screening box 2, which instantly draws away the dust generated during the screening process and sends it to the dust collector bag for collection. This can control dust dispersion to the greatest extent from the source, greatly improve the collection efficiency, and create a clean working environment, which is conducive to long-term operation.
