Description

Technical Field

[0001] This utility model relates to the field of powder screening technology, and more specifically to a magnetic powder screening and filtering device. Background Technology

[0002] In the powder processing industry, powder sieving and filtration is a crucial step in ensuring product quality. Traditional processes often employ manual magnetic sieving, requiring operators to manually sift powder piece by piece using a magnetic tool. This method has several drawbacks. First, it relies entirely on manual operation, requiring a significant investment of manpower, resulting in low sieving efficiency and substantial time costs, making it unsuitable for large-scale production. Second, during manual operation, human factors can affect the consistency of sieving force, range, and time, leading to inconvenience and the creation of blind spots that prevent the complete removal of impurities, impacting product purity and yield. As the industry's demands for production efficiency and product quality continue to rise, traditional manual magnetic sieving is no longer adequate. There is an urgent need for a magnetic sieving and filtration device that enables automated material transfer and highly efficient, precise sieving to address the problems of wasted manpower, high time costs, operational inconvenience, and incomplete sieving inherent in existing technologies. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a magnetic powder screening and filtration device, which aims to solve the technical problems of wasted manpower and incomplete screening in the existing powder screening devices.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A magnetic powder sieving and filtering device includes: a feed hopper, a screening tower, a frame, and a discharge component. The screening tower is mounted on the frame and has a screening bin inside. A discharge hopper is mounted on the frame, and the discharge component is located below the discharge hopper. The feed hopper, the screening bin, the discharge hopper, and the discharge component are connected sequentially from top to bottom. At least one set of rotary motors is provided on the front of the screening tower, and at least one set of magnetic assemblies is provided inside the screening bin. The magnetic assemblies are rotatably connected to the rotary motors.

[0006] In one embodiment, the output end of the rotary motor is provided with a connecting shaft, which passes through the front of the screening tower, enters the screening bin, and is movably connected to the back of the screening tower.

[0007] In one embodiment, the magnetic attraction assembly includes a plurality of electromagnetic rods and two connecting plates respectively fixedly connected to both ends of the electromagnetic rods, wherein the plurality of electromagnetic rods are arranged in a circumferential array on the connecting plates.

[0008] In one embodiment, the connecting shaft passes sequentially through the front of the screening tower, the two connecting plates, and is detachably connected to the back of the screening tower.

[0009] In one embodiment, the screening tower has two sets of rotary motors arranged from top to bottom on its front side, and the screening bin has two sets of magnetic suction components arranged from top to bottom. The two sets of magnetic suction components are respectively connected to the two sets of rotary motors.

[0010] In one embodiment, the two sets of rotary motors rotate in opposite directions.

[0011] In one embodiment, the opening of the feed hopper is provided with a feed adjustment plate and a feed adjustment block. The feed adjustment plate is rotatably connected to the feed hopper, and the feed adjustment block is movably connected to the feed hopper. The feed adjustment block and the feed adjustment plate together form the feed inlet of the feed hopper.

[0012] In one embodiment, a screen disc, a waste disc, or a blockage disc is detachably connected to the outlet at the lower end of the screening bin.

[0013] In one embodiment, the outer wall of the hopper is provided with a connecting hook, and the material dropping component is hooked onto the connecting hook.

[0014] In one embodiment, the rotary motor is equipped with a controller, which is used to control the on / off state, rotation direction and rotation speed of the rotary motor.

[0015] The advantages of this invention compared to existing technologies are as follows: By systematically connecting the feed hopper, screening bin, discharge hopper, and discharge component, an automated material transport channel is constructed, allowing powder to flow smoothly under gravity without frequent manual intervention. The rotating motor on the front of the screening tower is linked to the magnetic suction component inside the screening bin. The motor drives the magnetic suction component to rotate continuously, achieving omnidirectional, dead-angle-free magnetic screening. Compared to manual operation, this greatly improves screening efficiency and accuracy, ensuring that impurities in the powder are fully adsorbed and removed. This device transforms the complex manual powder screening process into automated mechanical operation, effectively solving the problems of wasted manpower and incomplete screening inherent in traditional manual magnetic powder screening.

[0033] See Figures 1 to 9 As shown in the figure, this utility model embodiment discloses a magnetic powder sieving and filtering device, including: a feeding hopper 1, a screening tower 2, a frame 5, and a discharge component 6. The screening tower 2 is disposed on the frame 5, and a screening bin 21 is provided inside the screening tower 2. A discharge hopper 51 is provided on the frame 5, and the discharge component 6 is disposed below the discharge hopper 51. The feeding hopper 1, the screening bin 21, the discharge hopper 51, and the discharge component 6 are connected sequentially from top to bottom. At least one set of rotary motors 3 is provided on the front of the screening tower 2, and at least one set of magnetic suction components 4 is provided inside the screening bin 21. The magnetic suction components 4 are rotatably connected to the rotary motors 3.

[0034] Specifically, the magnetic powder sieving and filtering device in this embodiment mainly consists of a feed hopper 1, a screening tower 2, a frame 5, and a discharge component 6. The frame 5 serves as the supporting structure for the entire device, on which the screening tower 2 is securely mounted. The screening tower 2 contains a screening bin 21 for holding powder and performing screening operations. A discharge hopper 51 is also provided on the frame 5, and the discharge component 6 is located below the discharge hopper 51. The feed hopper 1, screening bin 21, discharge hopper 51, and discharge component 6 are sequentially connected from top to bottom, forming a powder transmission channel. At least one set of rotary motors 3 is installed on the front of the screening tower 2, and at least one set of magnetic suction components 4 is correspondingly provided inside the screening bin 21. The magnetic suction components 4 are rotatably connected to the rotary motors 3. During operation, gravity causes the powder to fall naturally within the channel, while the rotary motors 3 drive the magnetic suction components 4 to rotate, adsorbing and screening magnetic impurities in the powder. Furthermore, during operation, the powder enters from the feed hopper 1, passes through the screening bin 21 and the discharge hopper 51 in sequence, and finally falls into the discharge component 6. During the process of passing through the screening bin 21, the rotating magnetic suction component 4 adsorbs magnetic impurities, thereby realizing automated powder screening and filtration. Compared with manual operation, it greatly improves screening efficiency and accuracy and reduces labor costs.

[0035] In one embodiment, the output end of the rotary motor 3 is provided with a connecting shaft 31, which passes through the front of the screening tower 2, enters the screening bin 21, and is movably connected to the back of the screening tower 2.

[0036] Specifically, the output end of the rotary motor 3 is equipped with a connecting shaft 31. This connecting shaft 31 passes through the front of the screening tower 2 and enters the screening bin 21, and is movably connected to the back of the screening tower 2. The principle of this design is to stably transmit the power of the rotary motor 3 to the magnetic suction component 4 inside the screening bin 21 through the connecting shaft 31, ensuring that the magnetic suction component 4 can rotate stably. During operation, after the rotary motor 3 starts, the connecting shaft 31 rotates accordingly, thereby driving the magnetic suction component 4 to rotate, thus ensuring the stability and reliability of the rotation of the magnetic suction component 4 and avoiding poor screening effect due to unstable power transmission.

[0037] In one embodiment, the magnetic attraction component 4 includes a plurality of electromagnetic rods 41 and two connecting plates 42 respectively fixedly connected to the two ends of the electromagnetic rods 41, and the plurality of electromagnetic rods 41 are arranged in a circumferential array on the connecting plates 42.

[0038] Specifically, the magnetic attraction component 4 includes several electromagnetic rods 41 and two connecting plates 42 fixedly connected to both ends of the electromagnetic rods 41. The electromagnetic rods 41 are arranged in a circumferential array on the connecting plates 42. By forming a magnetic attraction structure with multiple electromagnetic rods 41, the magnetic attraction area is increased, improving the adsorption capacity for magnetic impurities. During operation, the rotary motor 3 drives the magnetic attraction component 4 to rotate, and the magnetic field generated by the electromagnetic rods 41 adsorbs magnetic impurities in the powder passing through the screening bin 21. Compared with a single magnetic rod, it can more comprehensively adsorb impurities and improve the thoroughness of screening. It is understood that the number of electromagnetic rods 41 is not limited in this embodiment. In application, the number and length of electromagnetic rods 41 can be adjusted according to actual needs to adapt to the screening of powders of different types and particle sizes.

[0039] In one embodiment, the connecting shaft 31 passes through the front of the screening tower 2, the two connecting plates 42 in sequence, and is detachably connected to the back of the screening tower 2.

[0040] Specifically, the connecting shaft 31 passes sequentially through the front of the screening tower 2, through two connecting plates 42, and is detachably connected to the back of the screening tower 2, thereby enabling the installation and removal of the magnetic suction component 4, facilitating maintenance and replacement of the magnetic suction component 4. During operation, the connecting shaft 31 securely connects to the magnetic suction component 4, transmitting power from the rotating motor 3 to the magnetic suction component 4, reducing equipment maintenance difficulty and improving maintainability. More specifically, the connection between the connecting shaft 31 and the back of the screening tower 2 can be secured with bolts, which does not affect rotation while facilitating disassembly.

[0041] In one embodiment, the screening tower 2 is provided with two sets of rotary motors 3 from top to bottom on the front, and the screening bin 21 is provided with two sets of magnetic suction components 4 from top to bottom. The two sets of magnetic suction components 4 are respectively connected to the two sets of rotary motors 3.

[0042] Specifically, the screening tower 2 has two sets of rotary motors 3 arranged from top to bottom on its front side, and two sets of magnetic suction components 4 arranged from top to bottom inside the screening bin 21. The two sets of magnetic suction components 4 are respectively connected to the two sets of rotary motors 3. By increasing the number of magnetic suction components 4 and rotary motors 3, the powder is screened twice, further improving the screening accuracy and effect. During operation, the two sets of magnetic suction components 4 rotate under the drive of their respective rotary motors 3, sequentially performing magnetic screening on the powder passing through the screening bin 21, achieving more efficient and thorough screening. Compared to a single set of magnetic suction components 4, it can better remove magnetic impurities from the powder. In a more specific implementation, the installation height and spacing of the two sets of magnetic suction components 4 can be adjusted according to the powder impurity content and screening requirements. It is understood that two sets of rotary motors 3 and magnetic suction components 4 are preferably used in this embodiment, but in specific applications, three or more sets of magnetic suction components 4 and rotary motors 3 can be set according to the powder and actual production needs to meet higher precision screening requirements.

[0043] Furthermore, the two sets of rotary motors 3 rotate in opposite directions.

[0044] Specifically, the two sets of rotary motors 3 rotate in opposite directions, causing the two sets of magnetic suction components 4 to generate opposite stirring effects. This makes the powder more evenly mixed in the screening bin 21, allowing magnetic impurities to come into more thorough contact with the magnetic suction components 4, thus improving the adsorption effect. During operation, the two sets of rotary motors 3 drive the magnetic suction components 4 to rotate in opposite directions, stirring and screening the powder, improving the comprehensiveness and thoroughness of screening, and reducing blind spots. In more specific implementations, the speed and direction of the two sets of rotary motors 3 can be precisely adjusted by the controller 7 to achieve the best screening effect.

[0045] In one embodiment, the opening of the feed hopper 1 is provided with a feed adjustment plate 11 and a feed adjustment block 12. The feed adjustment plate 11 is rotatably connected to the feed hopper 1, and the feed adjustment block 12 is movably connected to the feed hopper 1. The feed adjustment block 12 and the feed adjustment plate 11 form the feed inlet of the feed hopper 1.

[0046] Specifically, the opening of the feed hopper 1 is equipped with a feed regulating plate 11 and a feed regulating block 12. The feed regulating plate 11 is rotatably connected to the feed hopper 1, and the feed regulating block 12 is movably connected to the feed hopper 1. The feed regulating block 12 and the feed regulating plate 11 form the feed inlet of the feed hopper 1. By adjusting the positions of the feed regulating plate 11 and the feed regulating block 12, the size of the feed inlet is controlled, thereby adjusting the feeding speed and flow rate of the powder. During operation, according to the screening requirements, the operator can manually or through an electric device adjust the feed regulating plate 11 and the feed regulating block 12 to change the size of the feed inlet, thereby achieving flexible control of the feeding process and avoiding the impact of excessively fast or slow feeding on the screening effect. It is understood that an electric regulating valve can also be used to automatically adjust the feed flow rate through sensors and a control system; however, this embodiment does not impose further limitations.

[0047] Furthermore, in this embodiment, the feed regulating plate 11 is rotatably connected to the feed hopper 1, and its rotation function is achieved through a hinge or shaft connection. The rotation center of the rotating shaft 111 is usually set at one edge of the feed hopper 1 to facilitate changing the shape and size of the feed inlet by rotation. The feed regulating block 12 is movably connected to the feed hopper 1. A slide rail 121 is provided on the inner wall of the feed hopper 1, and a corresponding slider 122 is provided on the feed regulating block 12, allowing it to slide horizontally along the slide rail 121 within the feed hopper 1. During operation, the feed regulating plate 11 and the feed regulating block 12 cooperate with each other. The operator can manually rotate the feed regulating plate 11 and move the feed regulating block 12 simultaneously according to the actual screening needs. When it is necessary to increase the feed flow rate, the feed regulating plate 11 is rotated to a larger opening angle, and the feed regulating block 12 is moved simultaneously to enlarge the feed inlet formed between the two; if it is necessary to reduce the feed flow rate, the operation is reversed. In this way, the speed and flow rate of powder entering the screening bin 21 can be precisely controlled, ensuring the stability and efficiency of the screening operation. In practical applications, electric push rods can also be used to drive the feed adjustment plate 11 and the feed adjustment block 12. The push rods can be extended and retracted by the motor to achieve automatic adjustment. It can also be connected to the control system to adjust the feed flow rate in real time according to the operating status of the screening equipment. The specific implementation method is not limited in this embodiment.

[0048] In one embodiment, a screen disc 22, a waste disc 23, or a blockage disc 24 are detachably connected to the outlet at the lower end of the screening bin 21.

[0049] Specifically, a screen disc 22, a waste disc 23, or a blocking disc 24 can be detachably connected to the outlet at the lower end of the screening bin 21 to meet different screening needs and working scenarios. When the powder contains non-magnetic impurities and further screening is required, the screen disc 22 can be installed; when it is necessary to collect adsorbed impurities, the waste disc 23 can be installed; when the equipment stops working or needs cleaning, the blocking disc 24 can be installed to enclose the screening device. During operation, different discs can be selected and installed according to actual needs to achieve corresponding functions, making the equipment more versatile and flexible.

[0050] In one embodiment, the outer wall of the hopper 51 is provided with a connecting hook 511, and the material dropping member 6 is hooked on the connecting hook 511.

[0051] Specifically, the outer wall of the hopper 51 is provided with a connecting hook 511, and the material discharge component 6 is hooked onto the connecting hook 511. This simple hooking method connects the material discharge component 6 to the hopper 51, facilitating its installation, disassembly, and replacement. During operation, the material discharge component 6 is stably hooked onto the connecting hook 511, receiving the powder falling from the hopper 51, reducing the difficulty of equipment installation and maintenance, and improving the equipment's practicality. It is understood that in this embodiment, the material discharge component 6 can be a collection bag, hooked onto the connecting hook 511, so that the screened material falls directly into the collection bag for collection. In other embodiments, a collection box or collection bucket, separate from the frame 5, can also be used and placed directly below the hopper 51 to collect the screened material. The form of the material discharge component 6 is not specifically limited in this embodiment and can be adapted according to actual needs.

[0052] In one embodiment, the rotary motor 3 is provided with a controller 7, which is used to control the on / off state, rotation direction and rotation speed of the rotary motor 3.

[0053] Specifically, the rotary motor 3 is equipped with a controller 7, which controls the on / off state, rotation direction, and rotation speed of the rotary motor 3. The controller 7 enables intelligent control of the rotary motor 3, thereby precisely adjusting the working state of the magnetic suction component 4. During operation, operators can set the on / off state, direction, and speed of the rotary motor 3 through the controller 7 according to the characteristics of the powder and screening requirements. This achieves automated and precise control of the screening process, adapting to different work needs and improving screening efficiency and quality.

[0054] In summary, the specific working process of a magnetic powder sieving and filtering device in this embodiment is as follows:

[0055] Remove the blockage plate 24, and the powder to be screened enters the device from the feed hopper 1. The feed adjustment plate 11 and feed adjustment block 12 at the opening of the feed hopper 1 can flexibly adjust the size of the feed inlet, accurately control the feeding speed and flow rate of the powder, and ensure that the subsequent screening operation is carried out stably.

[0056] After the powder enters the screening bin 21 inside the screening tower 2, the rotary motor 3 on the front of the screening tower 2 starts to work, and the connecting shaft 31 at its output end drives the magnetic attraction component 4 inside the screening bin 21 to rotate. The magnetic attraction component 4 is composed of several electromagnetic rods 41 and connecting plates 42, which are arranged in a circumferential array. The magnetic field generated during the rotation can adsorb magnetic impurities in the powder in all directions without dead angles.

[0057] The powder, after being magnetically screened, continues downward and falls through the hopper 51 on the frame 5 into the discharge component 6 below. The connecting hook 511 on the outer wall of the hopper 51 is attached to the discharge component 6, facilitating its installation and replacement. A screen disc 22 can be optionally installed at the lower outlet of the screening bin 21 for further impurity screening, depending on requirements.

[0058] After the powder screening is completed, the drying screen is removed and replaced with the waste tray 23. After the power of the electromagnetic rod 41 is turned off to demagnetize the magnetic component 4, the rotary motor 3 is started again to make the metal iron debris adsorbed on the surface of the magnetic component 4 fall into the waste tray 23.

[0059] After all the debris and waste has been removed and collected, turn off the rotary motor 3, turn off the power, and install the blockage plate 24.

[0060] Throughout the process, the controller 7 on the rotary motor 3 can regulate the on / off state, rotation direction and speed of the rotary motor 3, as well as the magnetic attraction force of the electromagnetic rod 41, to adapt to the screening needs of powders with different characteristics, realize automated and precise powder screening and filtration, effectively solve the problems of waste of manpower, low efficiency and incomplete screening in traditional manual powder screening, and significantly improve production efficiency and product quality.
