Description
Technical Field
[0001] This utility model belongs to the technical field of screening devices, and in particular relates to a grading and screening device for deoxidized aluminum particles in steelmaking. Background Technology
[0002] Steelmaking deoxidizing aluminum granules are a material used for deoxidation during the steelmaking process. Its main component is aluminum, which can react with oxygen in molten steel to reduce oxygen content, improve steel quality, and enhance steel performance.
[0003] Most steelmaking deoxidation aluminum particle grading and screening devices have several drawbacks, such as: existing devices generate dust during operation, which overflows and pollutes the working environment; the filters in existing devices require frequent maintenance, and the filters are mostly fixed with bolts, which are time-consuming to remove using tools and impossible to remove without them. Therefore, we propose a steelmaking deoxidation aluminum particle grading and screening device. Utility Model Content
[0004] The purpose of this invention is to provide a steelmaking deoxidation aluminum particle grading and screening device to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a steelmaking deoxidation aluminum particle grading and screening device, including a shell, a vibrator, several fixed frames and several aluminum particle filter screens, and further including:
[0006] A fixed plate is inserted and installed on the left side of the housing. Several limiting strips are inserted and installed inside the fixed plate. Several fixed frames are inserted and installed inside the housing, and the fixed frames are respectively fixedly connected to the several limiting strips. Several aluminum particle filter screens are respectively fixedly installed on the several fixed frames. The vibrator is fixedly installed on the front side of the housing.
[0007] A fixing component, located within a fixing plate, is used to fix the position of the fixing plate;
[0008] Several through holes are provided, all of which are located inside the housing and on the right side of several fixed frames. Two negative pressure fans are fixedly installed on the right side of the housing. A rectangular frame is fixedly installed inside the housing and on the left side of the negative pressure fans. A dust filter is fixedly installed inside the rectangular frame. A sliding rod is slidably installed inside the housing and on the left side of the dust filter.
[0009] A drive assembly, located within the housing, is used to drive the sliding rod to slide.
[0010] In this technical solution, when it is necessary to filter aluminum particles in a graded manner, the aluminum particles are first poured into the housing, and then the vibrator is started. The vibrator drives several aluminum particle filter screens to vibrate, and the several aluminum particle filter screens can filter the aluminum particles in a graded manner. Larger aluminum particles will stay at the top of the uppermost aluminum particle filter screen, medium-sized aluminum particles will stay at the top of the middle aluminum particle filter screen, and smaller aluminum particles will stay at the top of the bottommost aluminum particle filter screen, so that the aluminum particles can be graded and filtered.
[0011] When it is necessary to repair several aluminum particle filter screens, the fixing plate can be removed through the fixed components. The fixing plate will then take out several fixing frames, allowing for the repair of several aluminum particle filter screens. It is also convenient to remove the aluminum particles that have been filtered through the filter screens. The fixing plate and several fixing frames can be re-fixed into the housing through the fixed components, making it convenient to repair several aluminum particle filter screens. The operation is convenient and simple and does not require the use of tools.
[0012] Two negative pressure fans are activated, which draw dust from the aluminum particles through several through-holes into the dust filter. The dust filter blocks the dust, ensuring it does not spill out. A drive mechanism drives a sliding rod to slide rapidly, which then taps the dust filter, vibrating it to remove dust and preventing clogging during use.
[0013] In the above technical solution, the fixing component further includes:
[0014] A limiting groove is formed within a fixed plate. A disc is rotatably mounted within the limiting groove. Two guide grooves are formed on the disc. Guide posts are slidably mounted within each of the two guide grooves. A limiting plate is fixedly mounted at one end of each of the two guide posts. Several sliding posts are fixedly mounted on each of the two limiting plates. A first spring is sleeved on each of the sliding posts. The two ends of the first springs are respectively fixedly connected to the limiting plate and the inner wall of the limiting groove. The sides of the two limiting plates that are far apart from each other pass through the limiting groove and extend into the housing. The sides of the two limiting plates that are far apart from each other are inserted into the housing. The two limiting plates and the several sliding posts are slidably connected to the limiting groove.
[0015] In this technical solution, when it is necessary to repair several aluminum particle filter screens, first rotate the disc forward. The disc drives two guide posts away from each other through two guide grooves. The two guide posts drive two limiting plates to slide and move closer to each other. At the same time, several first springs are compressed and contracted. After both limiting plates are detached from the housing, the fixing plate can be removed. The fixing plate drives several fixing frames to be removed. At this time, several aluminum particle filter screens can be repaired, and it is convenient to remove the aluminum particles that have been filtered on the filter screens. By reversing the above operation, the fixing plate and several fixing frames can be fixed back into the housing, which is convenient for repairing several aluminum particle filter screens. The operation is convenient and simple and does not require the use of tools.
[0016] In the above technical solution, the driving component further includes:
[0017] The power chamber is located inside the housing and above the dust filter. A motor is fixedly installed on the top of the housing. The output shaft of the motor extends through the housing into the power chamber and is fixedly installed with a rotating rod. Two rotating columns are rotatably installed on the rotating rod. The output shaft of the motor is rotatably connected to the housing and the power chamber.
[0018] A fixed rod is fixedly installed inside the power cavity. A second spring is sleeved on the fixed rod. A sliding strip is slidably installed on the fixed rod. A connecting rod is fixedly installed on one side of the sliding strip. The fixed rod and the connecting rod are slidably connected. The lower end of the connecting rod passes through the power cavity and is fixedly connected to the sliding rod. The rotating rod is rotatably connected to the power cavity. The sliding strip and the connecting rod are both slidably connected to the power cavity.
[0019] In this technical solution, two negative pressure fans are activated. These fans draw dust from aluminum particles through several through-holes into a dust filter. The dust filter traps the dust, preventing it from escaping to the outside. The motor is then started, powering on and driving a rotating rod. This rotating rod drives two rotating columns. One of the rotating columns presses against a sliding strip, causing it to slide towards the second spring. The sliding strip then drives a connecting rod to slide, simultaneously compressing and contracting the second spring. The connecting rod then drives the sliding rod to slide. When one of the rotating columns is no longer in contact with the sliding strip, the sliding strip and connecting rod quickly slide away from the second spring due to the spring's rebound force. The connecting rod then drives the sliding rod to slide, finally causing the sliding rod to strike the dust filter, vibrating off the dust and preventing clogging during use.
[0020] In the above technical solution, a collection box is further installed inside the housing and below the sliding rod.
[0021] In this technical solution, it is ensured that dust can enter the collection box and be collected.
[0022] In the above technical solution, one end of the disc extends through the limiting groove to the outside and is fixedly installed with a handle.
[0023] In this technical solution, a handle is provided to facilitate the user's rotation of the disc.
[0024] In the above technical solution, furthermore, the filtration accuracy of the plurality of aluminum particle filter screens increases sequentially from top to bottom.
[0025] In this technical solution, larger aluminum particles are ensured to remain at the top of the uppermost aluminum particle filter screen, medium-sized aluminum particles are placed at the top of the middle aluminum particle filter screen, and smaller aluminum particles are placed at the top of the lowermost aluminum particle filter screen, thus enabling the aluminum particles to be graded and filtered.
[0026] In the above technical solution, furthermore, all of the through holes are arranged at an angle.
[0027] In this technical solution, dust can enter the through holes, while aluminum particles can also slide downwards and be screened again inside the through holes.
[0028] The beneficial effects of this utility model are:
[0029] 1. This steelmaking deoxidation aluminum particle grading and screening device allows for the removal of a fixed plate via a set fixing component when several aluminum particle filter screens need maintenance. The fixed plate then pulls out several fixed frames, enabling maintenance of the aluminum particle filter screens and facilitating the removal of the filtered aluminum particles. The fixed plate and several fixed frames can then be re-fixed into the housing via the set fixing component, facilitating maintenance of the aluminum particle filter screens. The operation is convenient and simple, requiring no tools.
[0030] 2. This steelmaking deoxidation aluminum particle grading and screening device starts with two negative pressure fans. The two negative pressure fans can draw the dust in the aluminum particles into the dust filter screen through several through holes. The dust filter screen can block the dust and ensure that the dust does not overflow to the outside. Through the set drive component, the sliding rod can be driven to slide quickly. Finally, the sliding rod taps the dust filter screen, which can shake off the dust attached to the dust filter screen and ensure that the dust filter screen will not be blocked during use.

The aluminum particles can be graded and filtered.
[0053] When it is necessary to repair several aluminum particle filter screens 6, the fixing plate 3 can be removed through the fixed components. The fixing plate 3 will drive several fixing frames 5 to be removed. At this time, several aluminum particle filter screens 6 can be repaired, and it is convenient to remove the aluminum particles that have been filtered on several aluminum particle filter screens 6. Through the fixed components, the fixing plate 3 and several fixing frames 5 can be fixed back into the housing 1, which is convenient for repairing several aluminum particle filter screens 6.

[0054] Two negative pressure fans 7 are activated. The two negative pressure fans 7 can draw the dust in the aluminum particles into the dust filter screen 9 through several through holes 26. The dust filter screen 9 can block the dust and ensure that the dust does not overflow to the outside. Through the set drive component, the sliding rod 10 can be driven to slide quickly. Finally, the sliding rod 10 taps the dust filter screen 9, which can shake off the dust attached to the dust filter screen 9 and ensure that the dust filter screen 9 will not be blocked during use.
[0055] In this embodiment, the fixing component includes:
[0056] A limiting groove 28 is formed within a fixed plate 3. A disc 11 is rotatably mounted within the limiting groove 28. Two guide grooves 12 are formed on the disc 11. Guide posts 13 are slidably mounted within each of the two guide grooves 12. A limiting plate 14 is fixedly mounted at one end of each of the two guide posts 13. Several sliding posts 25 are fixedly mounted on each of the two limiting plates 14. A first spring 15 is sleeved on each of the several sliding posts 25. The two ends of the several first springs 15 are fixedly connected to the inner walls of the limiting plate 14 and the limiting groove 28, respectively. The sides of the two limiting plates 14 that are far apart from each other pass through the limiting groove 28 and extend into the housing 1. The sides of the two limiting plates 14 that are far apart from each other are inserted into the housing 1. The two limiting plates 14 and the several sliding posts 25 are slidably connected to the limiting groove 28.
[0057] When it is necessary to repair several aluminum particle filter screens 6, first rotate the disc 11 in the forward direction. The disc 11 drives the two guide posts 13 away from each other through the two guide grooves 12. The two guide posts 13 drive the two limiting plates 14 to slide and move closer to each other. At the same time, several first springs 15 are compressed and contracted. After the two limiting plates 14 are detached from the housing 1, the fixing plate 3 can be taken out. The fixing plate 3 drives several fixing frames 5 to be taken out. At this time, several aluminum particle filter screens 6 can be repaired, and it is convenient to take out the aluminum particles that have been filtered on several aluminum particle filter screens 6. Through the above reverse operation, the fixing plate 3 and several fixing frames 5 can be fixed back into the housing 1, which is convenient for repairing several aluminum particle filter screens 6. The operation is convenient and simple and does not require the use of tools.
[0058] In this embodiment, the driving component includes:
[0059] The power chamber 16 is located inside the housing 1 and above the dust filter screen 9. A motor 17 is fixedly installed on the top of the housing 1. The output shaft of the motor 17 extends through the housing 1 into the power chamber 16 and is fixedly installed with a rotating rod 18. Two rotating columns 19 are rotatably installed on the rotating rod 18. The output shaft of the motor 17 is rotatably connected to the housing 1 and the power chamber 16.
[0060] A fixed rod 20 is fixedly installed inside the power cavity 16. A second spring 21 is sleeved on the fixed rod 20. A sliding strip 22 is slidably installed on the fixed rod 20. A connecting rod 23 is fixedly installed on one side of the sliding strip 22. The fixed rod 20 and the connecting rod 23 are slidably connected.

The sliding strip 22 and the connecting rod 23 are both slidably connected to the power cavity 16.
[0061] The process involves activating two negative pressure fans 7, which draw dust from aluminum particles through several through-holes 26 onto a dust filter 9. The dust filter 9 traps the dust, preventing it from escaping to the outside. Then, a motor 17 is activated, driving a rotating rod 18 to rotate. This rotating rod 18 drives two rotating columns 19 to rotate. One of the rotating columns 19 presses against a sliding strip 22, causing it to slide towards the second spring 21. The sliding strip 22 then drives a connecting rod 23 to slide, simultaneously compressing and contracting the second spring 21. The connecting rod 23 then drives a sliding rod 10 to slide. When one of the rotating columns 19 is no longer in contact with the sliding strip 22, the sliding strip 22 and connecting rod 23 quickly slide away from the second spring 21 due to the rebound force of the second spring 21. The connecting rod 23 then drives a sliding rod 10 to slide. Finally, the sliding rod 10 strikes the dust filter 9, vibrating off the dust adhering to it and preventing clogging during use.

[0072] In this embodiment, the filtration accuracy of the aluminum particle filter screens 6 increases sequentially from top to bottom.
[0073] In this system, larger aluminum particles are ensured to remain at the top of the uppermost aluminum particle filter screen 6, medium-sized aluminum particles are placed at the top of the middle aluminum particle filter screen 6, and smaller aluminum particles are placed at the top of the lowermost aluminum particle filter screen 6, thus enabling the aluminum particles to be graded and filtered.
[0074] Example 5:
[0075] This embodiment provides a steelmaking deoxidation aluminum particle grading and screening device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0076] In this embodiment, several through holes 26 are all inclined.
[0077] This design ensures that dust can enter the through-hole 26, while aluminum particles can also slide downwards within the through-hole 26 for re-screening.
[0078] It is worth noting that the vibrator 2 involved in this utility model is a vibrator 2 with product number MVE horizontal vibrating motor produced by Shaoxing Ouli-Wolong Vibration Machinery Co., Ltd. The vibrator 2 involved in this utility model is existing technology, which can be fully implemented by those skilled in the art, and there is no need to elaborate. The content protected by this utility model does not involve any improvement to the structure and working principle of the vibrator 2.
[0079] Working principle: When aluminum particles need to be graded and filtered, the aluminum particles are first poured into the housing 1, and then the vibrator 2 is started. The vibrator 2 drives several aluminum particle filter screens 6 to vibrate. The aluminum particle filter screens 6 can grade and filter the aluminum particles. Larger aluminum particles will stay at the top of the uppermost aluminum particle filter screen 6, medium-sized aluminum particles will stay at the top of the middle aluminum particle filter screen 6, and smaller aluminum particles will stay at the top of the bottommost aluminum particle filter screen 6. The aluminum particles can be graded and filtered.
[0080] When it is necessary to repair several aluminum particle filter screens 6, first turn the handle 27 forward and drive the disc 11 to rotate forward. The disc 11 drives the two guide posts 13 to move away from each other through the two guide grooves 12. The two guide posts 13 drive the two limiting plates 14 to slide and move closer to each other. Several sliding posts 25 slide, and several first springs 15 are compressed and contracted. When the two limiting plates 14 are detached from the housing 1, the fixing plate 3 can be taken out. The fixing plate 3 drives several fixing frames 5 to be taken out. At this time, several aluminum particle filter screens 6 can be repaired, and it is convenient to take out the aluminum particles that have been filtered on several aluminum particle filter screens 6. Through the above reverse operation, the fixing plate 3 and several fixing frames 5 can be fixed back into the housing 1, which is convenient for repairing several aluminum particle filter screens 6. The operation is convenient and simple and does not require the use of tools.
[0081] Two negative pressure fans 7 are started. The two negative pressure fans 7 can draw the dust in the aluminum particles into the dust filter screen 9 through several through holes 26. The dust filter screen 9 can block the dust and ensure that the dust does not overflow to the outside. The motor 17 is started. The motor 17 is powered on and drives the rotating rod 18 to rotate. The rotating rod 18 drives the two rotating columns 19 to rotate. One of the rotating columns 19 squeezes the sliding strip 22 and slides it towards the second spring 21. The sliding strip 22 drives the connecting rod 23 to slide. At the same time, the second spring 21 is compressed and contracted. The connecting rod 23 drives the sliding rod 10 to slide. When one of the rotating columns 19 is no longer in contact with the sliding strip 22, under the action of the rebound force of the second spring 21, the sliding strip 22 and the connecting rod 23 quickly slide away from the second spring 21. The connecting rod 23 drives the sliding rod 10 to slide. Finally, the sliding rod 10 knocks the dust filter screen 9, which can shake off the dust attached to the dust filter screen 9. Then the dust enters the collection box 24 and is collected to ensure that the dust filter screen 9 will not be blocked during use.
[0082] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
