Description

Technical Field

[0001] This utility model relates to the field of magnetic powder screening, and in particular to a multi-stage vibration screening device for magnetic powder. Background Technology

[0002] Magnetic powder, as an important industrial raw material, has a wide and crucial application in many fields such as magnetic material preparation, electronic component production, and magnetic coating manufacturing. Its particle size distribution, purity, and other characteristics directly affect the performance and quality of the final product. Therefore, precise screening of magnetic powder is an important step in ensuring product quality.

[0003] Existing magnetic particle screening methods typically involve pouring magnetic particles into a screening device and then performing multi-stage sieving. However, current equipment lacks the ability to disperse and level the magnetic particles. After entering the screening device, due to vibration and the inherent properties of the magnetic particles, they tend to attract each other and form clumps, causing blockage of the screen pores. This increases the difficulty of screening, reduces screening efficiency and quality, and causes inconvenience for subsequent use.

[0004] Therefore, it is necessary to design a multi-stage vibration screening device for magnetic powder that can simultaneously disperse and level the magnetic powder, prevent magnetic powder from clumping, improve screening efficiency and quality, facilitate subsequent use, and be easy to use. Utility Model Content

[0005] To overcome the shortcomings of current equipment that lacks the function of dispersing and leveling magnetic powder, which causes magnetic powder to easily attract each other and form clumps after entering the screening equipment due to vibration and the characteristics of the magnetic powder itself, leading to clogging of the screen pores, increasing the difficulty of screening, reducing screening efficiency and quality, and causing inconvenience for subsequent use, this utility model provides a multi-stage vibration screening device for magnetic powder that can simultaneously disperse and level the magnetic powder through multi-stage vibration screening, prevent magnetic powder from clumping, improve screening efficiency and quality, facilitate subsequent use, and is easy to use.

[0006] The technical solution is as follows: A multi-stage vibration screening device for magnetic powder includes a shell, a support frame, springs, a feed hopper, a screening component, and an anti-caking component. The left and right sides of the shell are slidably connected to two front and rear support frames, and springs are connected between the support frames and the shell. A feed hopper is connected to the upper left side of the shell. The shell is equipped with a screening component for multi-stage vibration screening of magnetic powder, and the feed hopper is equipped with an anti-caking component for dispersing and leveling the magnetic powder.

[0007] As an improvement to the above solution, the screening component includes a motor, an eccentric wheel, a first screen, a second screen, a third screen, a first collection frame, a second collection frame, and a third collection frame. The motor is connected to the lower front side of the outer casing, and the eccentric wheel is connected to the output shaft of the motor. The first screen is connected to the inner side of the middle of the feed hopper, the second screen is connected to the upper part of the outer casing, the third screen is connected to the lower part of the outer casing, the first collection frame is slidably engaged with the lower left part of the outer casing, the second collection frame is slidably engaged with the lower right part of the outer casing, and the third collection frame is slidably engaged with the lower middle part of the outer casing.

[0008] As an improvement to the above scheme, both the second and third screens are inclined.

[0009] As an improvement to the above solution, handles are provided on the first collection box, the second collection box, and the third collection box.

[0010] As an improvement to the above solution, the anti-caking component includes a transmission component, a reciprocating screw, and a pusher. The reciprocating screw is rotatably connected to the upper left part of the feed hopper. A transmission component is provided between the output shaft of the motor and the reciprocating screw. The pusher is threadedly connected to the reciprocating screw and is slidably connected to the feed hopper.

[0011] As an improvement to the above solution, the transmission assembly includes pulleys and a flat belt. The output shaft of the motor and the front of the reciprocating lead screw are both connected to pulleys. The pulley on the output shaft of the motor is located in front of the eccentric wheel, and a flat belt is wound between the pulleys.

[0012] Beneficial effects: 1. This utility model uses the rotation of the eccentric wheel, which, under the action of the eccentric wheel and the spring, causes the outer shell to vibrate, which in turn causes the feed hopper to vibrate, and the first, second and third screens to vibrate for multi-stage screening of magnetic powder. The reciprocating movement of the pusher frame disperses and flattens the magnetic powder, thereby enabling multi-stage vibration screening of magnetic powder while simultaneously dispersing and flattening it, preventing magnetic powder from clumping, improving screening efficiency and quality, facilitating subsequent use, and making it convenient to use.

[0013] 2. In the screening process, the outer shell of this utility model provides dust protection, thereby preventing the magnetic powder from flying away, improving the working environment, reducing the harm of dust to the health of operators, and improving the safety of use.

[0019] 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.

[0020] A multi-stage vibration screening device for magnetic powder, such as Figures 1-4 As shown, it includes a shell 1, a support frame 2, a spring 3, a feed hopper 6, a screening component, and an anti-caking component. The left and right sides of the shell 1 are slidably connected to the front and rear support frames 2. The support frames 2 are connected to the shell 1 by the spring 3. The upper left side of the shell 1 is connected to the feed hopper 6. The shell 1 is provided with a screening component for multi-stage vibration screening of magnetic powder. The feed hopper 6 is provided with an anti-caking component for dispersing and leveling the magnetic powder.

[0021] like Figures 1-3 As shown, the screening assembly includes a motor 4, an eccentric wheel 5, a first screen 7, a second screen 8, a third screen 9, a first collection frame 10, a second collection frame 11, and a third collection frame 12. The motor 4 is connected to the lower front side of the outer casing 1, and the eccentric wheel 5 is connected to the output shaft of the motor 4. The first screen 7 is connected to the inner side of the middle part of the feed hopper 6. The second screen 8 is connected to the upper part of the outer casing 1, and the third screen 9 is connected to the lower part of the outer casing 1. Both the second screen 8 and the third screen 9 are inclined to facilitate the sliding of magnetic powder. The first collection frame 10 is slidably engaged with the lower left part of the outer casing 1, the second collection frame 11 is slidably engaged with the lower right part of the outer casing 1, and the third collection frame 12 is slidably engaged with the lower middle part of the outer casing 1. Each of the first collection frame 10, the second collection frame 11, and the third collection frame 12 is provided with a handle to facilitate the removal of the first collection frame 10, the second collection frame 11, and the third collection frame 12 by hand.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, the anti-caking assembly includes a transmission assembly 13, a reciprocating screw 14, and a pusher 15. The reciprocating screw 14 is rotatably connected to the upper left part of the feed hopper 6. The transmission assembly 13 is provided between the output shaft of the motor 4 and the reciprocating screw 14. The transmission assembly 13 includes a pulley and a flat belt. The output shaft of the motor 4 and the front part of the reciprocating screw 14 are both connected to pulleys. The pulley on the output shaft of the motor 4 is located in front of the eccentric wheel 5. A flat belt is wound between the pulleys. The pusher 15 is threadedly connected to the reciprocating screw 14. The pusher 15 is slidably connected to the feed hopper 6.

[0023] This device can be used when multi-stage vibration screening of magnetic powder is required. The support frame 2 is brought into contact with the ground, and the magnetic powder is poured into the feed hopper 6, causing it to fall onto the first screen 7. Then, the motor 4 is started, driving the eccentric wheel 5 to rotate. Under the action of the eccentric wheel 5 and the spring 3, the outer casing 1 vibrates, which in turn causes the feed hopper 6 to vibrate, resulting in the vibration of the first screen 7 and causing the magnetic powder to fall. Simultaneously, this also drives the pulley to rotate, causing the flat belt to rotate and the reciprocating screw 14 to rotate. The rotation, under the action of the screw thread, causes the pusher 15 to reciprocate along the feed hopper 6, dispersing and leveling the magnetic powder. This allows the magnetic powder to fall onto the second screen 8, with the largest particles sliding down to the second collection frame 11 for collection. Continued vibration screening causes other magnetic powder to fall onto the third screen 9, with medium-sized particles sliding down to the first collection frame 10 for collection, and the smallest particles dripping into the third collection frame 12 for collection. This process further... The magnetic powder undergoes multi-stage vibration screening. Both the second screen 8 and the third screen 9 are inclined to facilitate the sliding of the magnetic powder. This allows for simultaneous multi-stage vibration screening and dispersion and leveling of the magnetic powder, preventing clumping and improving screening efficiency and quality. It is also convenient for subsequent use. During screening, the outer casing 1 provides dust protection, preventing magnetic powder from flying and improving the working environment. This reduces the health hazards of dust to operators and enhances safety. After screening, the motor 4 is turned off. The first collection frame 10, the second collection frame 11, and the third collection frame 12 are then moved and removed by pulling the handle. The magnetic powder in these frames is then collected and stored separately. Next, the first collection frame 10, the second collection frame 11, and the third collection frame 12 are brought into contact with the outer casing 1 and moved to install them. The device can then be used to continue screening magnetic powder.
