Description

Technical Field

[0001] This utility model relates to the field of metal impurity detection and separation technology, specifically to a particulate metal impurity detection and separation device. Background Technology

[0002] With the rapid development of modern industry, especially in precision manufacturing fields such as semiconductor manufacturing, new energy battery materials, high-end ceramics, and biomedicine, the purity requirements for raw materials and intermediate products are becoming increasingly stringent. Particulate matter, as a common form of matter in these fields, may carry trace amounts of metallic impurities such as iron, copper, nickel, chromium, and zinc on its surface or inside. Even in extremely low concentrations, these impurities can trigger catalytic side reactions, reduce the electrochemical performance of products, affect the structural stability of materials, and even lead to device failure during subsequent processes. Therefore, achieving effective detection and separation of metallic impurities in particulate matter has become a key link in ensuring product quality and improving production yield. Against this backdrop, developing a device that integrates detection and separation functions, capable of continuous and automated operation for specific particulate material flows, has become an important technological direction for improving the level of material purity control.

[0003] CN219210747U discloses an impurity detector with impurity removal function, relating to the field of impurity detector technology. It includes an impurity detector assembly with an impurity sample removal component on its side. This invention solves the problem of manual removal of metal particles in food when the impurity detector detects them. It achieves automatic removal of food containing metal particles by means of a sliding block fixedly connected to the output shaft of a telescopic cylinder, and an arc-shaped groove at one end of a push rod. When the impurity detector detects metal particles in the food, the telescopic cylinder is pushed linearly by external equipment, causing the sliding block to slide inside the sliding groove. This pushes the movable sleeve rod to push out the food containing metal particles, which then slides along the arc-shaped plate. Because the movable sleeve rod is movably connected to the support rod, it achieves automatic removal of food containing metal particles, replacing manual removal operations, reducing manual labor, and improving practicality.

[0004] In practical applications, existing technologies often suffer from material accumulation and agglomeration when separating metal impurities from particulate matter, resulting in missed detections. Furthermore, the conveying channel is prone to blockage, affecting continuous operation efficiency. Therefore, this invention designs a particulate matter metal impurity detection and separation device to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a particulate metal impurity detection and separation device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A particulate metal impurity detection and separation device includes a lower separation tank, an upper separation tank fixedly connected to the upper surface of the lower separation tank, a separation component installed in the inner cavity of the upper separation tank, and an adsorption component installed in the inner cavity of the lower separation tank. The separation component includes a rotating rod rotatably connected to the middle of the inner cavity of the upper separation tank, a plurality of stirring rods uniformly fixedly connected to the upper outer surface of the rotating rod, a spiral conveying blade fixedly connected to the middle of the rotating rod, a conveying pipe connected to the lower end of the lower separation tank, a separator cover fixedly connected to the inner cavity of the upper separation tank, and an adsorption component including an arc-shaped adsorption cover fixedly connected to the lower end of the rotating rod, a plurality of connecting rods uniformly fixedly connected to the outer surface of the arc-shaped adsorption cover, a spherical connecting block fixedly connected to one end of each connecting rod, and a limit ring fixedly connected to the side wall of the inner cavity of the upper separation tank.

[0008] Furthermore, multiple support legs are uniformly and fixedly connected to the lower surface of the lower separation barrel, and the lower end of the lower separation barrel is conical and connected to a discharge pipe.

[0009] Furthermore, a metal feeding pipe is connected to the outer surface of the lower separation tank, the metal feeding pipe is inclined and located above the separator cover.

[0010] Furthermore, the lower end of the upper separating barrel is conical and is connected to the lower separating barrel through a conveying pipe, and a feed inlet is provided on the upper surface of the upper separating barrel.

[0011] Furthermore, a drive motor is fixedly connected to the middle of the upper surface of the upper separation barrel, and the output shaft end of the drive motor passes through the upper separation barrel and is fixedly connected to the upper end of the rotating rod.

[0012] Furthermore, the spiral conveying blades are located inside the conveying pipe and abut against its inner wall; the opening of the partition cover is an upward-opening trumpet shape; and the opening of the partition cover is a downward-arching arc shape.

[0013] Furthermore, an electromagnetic induction metal detection coil is installed in the inner cavity of the lower separation tank, and a nozzle is embedded and fixed in the inner cavity of the lower separation tank. An air pump is installed on the nozzle. The electromagnetic induction metal detection coil is located below the conveying pipe, and the nozzle is located below the electromagnetic induction metal detection coil. A high-pressure nozzle is installed at one end of the nozzle located in the inner cavity of the lower separation tank.

[0014] Furthermore, the inner cavity of the limiting ring is provided with a limiting groove, the spherical connecting block slides in the inner cavity of the limiting groove, and the arc-shaped adsorption cover is an arc-shaped electromagnet with a wear-resistant layer fixed on its outer surface.

[0015] Beneficial effects: (1) This scheme uses the dual action of stirring rod and spiral conveying blade to fully disperse and uniformly convey the material before it enters the detection area, effectively preventing the problem of missed detection caused by metal lumps, while avoiding blockage of the conveying pipe, ensuring continuous and stable operation of the system. The funnel-shaped flow guide structure of the partition cover further optimizes the material distribution. The electromagnetic induction metal detection coil accurately identifies the metal impurities mixed in the material. The nozzle sprays at a 30° angle, which can effectively separate non-magnetic metals and avoid impacting qualified materials to avoid waste, ensuring that the rejection action is efficient and low-damage, and realizing efficient and accurate separation of metal impurities in particulate matter.

[0016] (2) In this scheme, after the material flows through the detection area, the pneumatic jet quickly removes the non-magnetic metal. At this time, the arc-shaped adsorption hood is energized and captures the fine ferromagnetic particles to make up for the possible omissions of the air blowing. The arc-shaped adsorption hood uses its strong magnetic field to adsorb the residual trace magnetic impurities for a second time, which greatly improves the purity of the final material and meets the requirements of high standard quality control.

[0017] (3) This solution cuts off the power supply to the arc-shaped adsorption hood to demagnetize it. The adsorbed metal impurities slide along the arc-shaped surface into the metal discharge pipe under the action of gravity. The continuous rotation of the arc-shaped adsorption hood can shake off the metal particles attached to the surface of the arc-shaped adsorption hood. There is no need for manual disassembly or knocking to clean it. This completely avoids the problem of frequent shutdowns of traditional equipment due to slag cleaning, reduces the labor intensity of operators, and also reduces the risk of equipment wear and pollution.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The utility model will be further described below with reference to the embodiments.

[0026] In some embodiments, please refer to the appendix to the instruction manual. Figures 1-5 A particulate metal impurity detection and separation device includes a lower separation tank 1, an upper separation tank 2 fixedly connected to the upper surface of the lower separation tank 1, a separation component 3 installed in the inner cavity of the upper separation tank 2, the separation component 3 including a rotating rod 302 rotatably connected to the middle of the inner cavity of the upper separation tank 2, a plurality of stirring rods 3021 uniformly fixedly connected to the upper outer surface of the rotating rod 302, a spiral conveying blade 304 fixedly connected to the middle of the rotating rod 302, a conveying pipe 303 connected to the lower end of the lower separation tank 1, and a separator cover 308 fixedly connected to the inner cavity of the upper separation tank 2.

[0027] Multiple support legs 102 are evenly fixedly connected to the lower surface of the lower separation tank 1. The lower end of the lower separation tank 1 is conical and connected to a feed pipe 101. A metal feed pipe 103 is connected to the outer surface of the lower separation tank 1. The metal feed pipe 103 is inclined and located above the separator hood 308. The lower end of the upper separation tank 2 is conical and connected to the lower separation tank 1 through a conveying pipe 303. A feed inlet 201 is opened on the upper surface of the upper separation tank 2. A drive motor 301 is fixedly connected to the middle of the upper surface of the upper separation tank 2. The output shaft of the drive motor 301 passes through the upper separation tank 2 and is fixedly connected to the upper end of the rotating rod 302. The rotary conveyor blade 304 is located inside the conveyor pipe 303 and abuts against its inner wall. The upper opening of the separator 308 is shaped like an upward-opening trumpet, and the lower opening of the separator 308 is shaped like a downward-arching arc. An electromagnetic induction metal detection coil 305 is installed inside the lower separation tank 1. A nozzle 306 is embedded and fixed inside the lower separation tank 1. An air pump 307 is installed on the nozzle 306. The electromagnetic induction metal detection coil 305 is located below the conveyor pipe 303, and the nozzle 306 is located below the electromagnetic induction metal detection coil 305. A high-pressure nozzle is installed at one end of the nozzle 306 inside the lower separation tank 1.

[0028] Material enters the upper separation tank 2 through the feed inlet 201. The drive motor 301 starts and drives the rotating rod 302 to rotate stably. The stirring rod 3021 on the rotating rod then stirs the material in all directions. The radial shear force breaks up the agglomerated particles in the material formed by moisture and compression, so that the material is evenly dispersed in the form of individual particles. This process can effectively prevent the agglomerated material from covering and obscuring metal impurities, ensuring that metal impurities can be fully exposed in the subsequent detection process, providing a prerequisite for accurate detection.

[0029] The dispersed material flows naturally to the conveying pipe 303 under the action of gravity. At the same time, the rotating rod drives the spiral conveying blades 304 to rotate continuously. The spiral pushing force pushes the material down steadily along the inner wall of the conveying pipe, ensuring the continuity of material conveying. It can also control the material to enter the lower separation tank 1 at a uniform flow rate, avoiding flow rate fluctuations that cause the material in the detection zone to be too thick or too thin, laying the foundation for the stability of subsequent metal detection. The separator 308 in the upper separation tank plays a guiding role, ensuring that most qualified non-metallic particles can slide down the lower separation tank 1 in an orderly manner through the separator 308, reducing the material residue on the tank wall.

[0030] Before entering the lower separation tank 1, the material passes through the detection zone of the electromagnetic induction metal detection coil 305. When the detection coil is working, an alternating current is passed through the transmitting coil to generate a symmetrically distributed alternating magnetic field. The two receiving coils on both sides are connected in reverse series to form a magnetic field balance. Under normal circumstances, there is no obvious signal output. When metal impurities, whether magnetic or non-magnetic, pass through the detection zone with the material, the magnetic field symmetry is broken, which eventually leads to an imbalance of the induced electromotive force of the two receiving coils and outputs a differential signal. This differential signal is amplified and filtered before being transmitted to the PLC control system. This can effectively avoid environmental interference such as magnetic fields in the workshop equipment, reduce false alarms, and ensure the accuracy of metal impurity identification.

[0031] After receiving the metal signal, the PLC controls the air pump 307 on the nozzle 306 to be turned on. The high-pressure airflow is precisely sprayed through the nozzle at an angle of 30° with the direction of material fall. This angle design can ensure that the airflow directly acts on the metal impurities and separate them from the material flow, while avoiding the airflow impacting qualified materials and causing material loss. The separated metal impurities are blown to the arc-shaped surface of the separator 308 and slide towards the metal discharge pipe 103 for discharge with the guidance of the arc-shaped surface, thus realizing the directional separation of non-magnetic metals.

[0032] In some embodiments, such as Figures 1-5 As shown, in a preferred embodiment of the present invention, an adsorption assembly 4 is installed in the inner cavity of the lower separation tank 1. The adsorption assembly 4 includes an arc-shaped adsorption cover 401 fixedly connected to the lower end of the rotating rod 302. Multiple connecting rods 402 are uniformly fixedly connected to the outer surface of the arc-shaped adsorption cover 401. A spherical connecting block 403 is fixedly connected to one end of the connecting rod 402. A limit ring 404 is fixedly connected to the side wall of the inner cavity of the upper separation tank 2.

[0033] The inner cavity of the limiting ring 404 has a limiting groove 405, the spherical connecting block 403 slides in the inner cavity of the limiting groove 405, and the arc-shaped adsorption cover 401 is an arc-shaped electromagnet with a wear-resistant layer wrapped and fixed on its outer surface.

[0034] When the arc-shaped adsorption hood 401 is energized, the arc-shaped adsorption hood 401, which rotates with the rotating rod 302, generates a strong magnetic field. The rotation process expands the magnetic adsorption coverage area, and the small magnetic metal impurities that may have been missed by the air blowing action are captured for the first time, further reducing the probability of missed detection. The qualified material after separation continues to fall, passes through the separator hood 308 and lands on the surface of the arc-shaped adsorption hood 401. At this time, the energized arc-shaped adsorption hood 401 still maintains a strong magnetic field state, which can perform secondary adsorption and capture of trace and small magnetic metal particles that may remain in the material, thoroughly removing the metal impurities that were not cleaned in the initial separation, and greatly improving the purity of the material. After the secondary separation, the qualified material without metal impurities slides down the arc-shaped surface of the adsorption hood and is finally discharged from the discharge pipe 101, completing the entire material purification process.

[0035] When the material separation operation is completed and the metal particles adsorbed on the arc-shaped adsorption hood 401 need to be removed, the PLC controls the arc-shaped adsorption hood 401 to be de-energized and demagnetized. After the adsorbed metal impurities lose their magnetic binding force, they naturally slide down the arc-shaped surface of the arc-shaped adsorption hood 401 to be discharged through the metal discharge pipe 103. The arc-shaped adsorption hood 401 continues to rotate, accelerating the shedding of metal particles. This process does not require manual disassembly of the equipment for cleaning, which not only avoids damage to the equipment caused by manual operation, but also greatly reduces the labor intensity of operators, realizes automatic cleaning of metal impurities, and improves the convenience of equipment use and operating efficiency.

[0036] Working principle: During the operation of the device, the material enters the upper separation tank 2 through the feed inlet 201. The drive motor 301 starts, driving the rotating rod 302 to rotate. The stirring rod 3021 on it fully agitates the material. Under the action of gravity, the material enters the conveying pipe 303. The spiral conveying blades 304 continue to rotate under the drive of the rotating rod, steadily pushing the material downward. At the same time, the separator 308 ensures that most non-metallic particles slide down to the lower separation tank 1 through the separator 308. Before entering the lower separation tank 1, the material first passes through the detection area of ​​the electromagnetic induction metal detection coil 305. After receiving the metal signal, two actions are triggered simultaneously: First, the air pump 307 on the nozzle 306 is turned on, and the high-pressure airflow passes through the nozzle. Precise spraying propels the metal onto the arc-shaped surface of the separator 308, where it is discharged through the metal discharge pipe 103. Secondly, the arc-shaped adsorption hood 401 is instantly energized, causing the separated material to fall continuously, passing through the separator 308 and landing on the arc-shaped adsorption hood 401. The energized hood 401 generates a strong magnetic field, firmly adsorbing the remaining fine metal particles onto its surface for secondary separation. The unadsorbed material continues to fall and is eventually discharged through the discharge pipe 101, completing the purification process. After material separation, when it is necessary to remove the adsorbed metal particles from the arc-shaped adsorption hood 401, the power is cut off and the magnetism is deactivated. The metal then falls into the discharge pipe 101 under gravity and is discharged, achieving automatic cleaning.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
