Description

Technical Field

[0001] This utility model belongs to the field of magnetic separator technology, specifically relating to an electromagnetic magnetic separator with a heat dissipation coil. Background Technology

[0002] Magnetic separators are among the most widely used and versatile machines in industry, suitable for separating substances with different magnetic properties. They are widely used in mining, ceramics, chemicals, food, and other industries. Magnetic separators use electromagnetic coils to generate a magnetic field around themselves, attracting magnetic materials and separating them from non-magnetic materials.

[0003] However, coils generate heat during operation. If heat dissipation is poor or the ambient temperature is too high, the coil temperature will rise excessively. Excessive temperature in the electromagnetic coil increases its resistance, reducing the current flowing through it, which in turn lowers the magnetic field strength. This ultimately leads to a decrease in magnetic force, preventing normal magnetic separation. It can also cause the internal wires of the coil to melt or burn, resulting in a short circuit. Utility Model Content

[0004] The purpose of this invention is to provide an electromagnetic separator with a heat dissipation coil to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0006] An electromagnetic separator with a heat dissipation coil includes a frame, a conveying mechanism mounted on the frame, a transmission mechanism connected to the conveying mechanism, and a magnetic separation mechanism mounted on the frame, located between the conveying mechanisms. The magnetic separation mechanism includes a housing, which is connected to the frame via a detachable connection mechanism. A winding drum is installed inside the housing, and a mounting frame is fixedly connected to the bottom of the winding drum. Several coaxial mounting rings are spaced apart on the mounting frame. Several winding support rods are uniformly fixedly mounted on the inner side of each mounting ring. Electromagnetic wire is wound around the outer side of the winding support rods of each mounting ring. Each layer of electromagnetic wire forms an electromagnetic wire layer on the winding support rods of each mounting ring. The electromagnetic wire passes around the winding support rods of each mounting ring sequentially from the inside to the outside along the innermost mounting ring, with a heat dissipation gap between adjacent electromagnetic wire layers.

[0007] As an improvement, an oil cooling mechanism is installed on the housing. The oil cooling mechanism includes a coil, which is fixedly connected to the inner wall of the winding drum. Both ends of the coil pass through the side wall of the housing and are connected to an oil cooler. The oil cooler is fixedly connected to the top of the housing.

[0008] As an improvement, the top of the housing is provided with a vent, which is connected to the winding drum, and a fan is installed inside the vent.

[0009] As an improvement, a temperature sensor is installed inside the housing, and the temperature sensor is electrically connected to a controller.

[0010] As an improvement, the conveying mechanism includes at least two conveying rollers, which are rotatably connected to the frame and connected to each other by a belt.

[0011] As an improvement, the transmission mechanism includes a motor, which is fixedly connected to the frame. A second sprocket is fixedly connected to the output end of the motor. A first sprocket that cooperates with the second sprocket is installed at one end of one of the conveying rollers. The first sprocket and the second sprocket are connected by a chain.

[0012] As an improvement, the detachable connection mechanism includes a lifting lug and a connecting ring. The lifting lug is fixedly connected to the housing, and the connecting ring is fixedly connected to the frame. The lifting lug and the connecting ring are connected by a hook.

[0013] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0022] like Figure 1-3 As shown, an electromagnetic magnetic separator with a heat dissipation coil includes a frame 8, characterized in that a conveying mechanism 7 is installed on the frame 8, the conveying mechanism 7 is connected to a transmission mechanism 2, and a magnetic separation mechanism 5 is installed on the frame 8, the magnetic separation mechanism 5 being located between the conveying mechanisms 7.

[0023] The magnetic separation mechanism 5 includes a housing 13, which is connected to the frame 8 by a detachable connection mechanism. A winding drum 17 is installed inside the housing 13. A mounting frame 16 is fixedly connected to the bottom of the winding drum 17. Several coaxial mounting rings 15 are installed at intervals on the mounting frame 16.

[0024] Several winding support rods 14 are uniformly fixedly installed on the inner side of each mounting ring 15. Electromagnetic wires are wound around the outer side of the winding support rods 14 of each mounting ring 15. Each electromagnetic wire forms an electromagnetic wire layer 19 on the winding support rod 14 of each mounting ring 15. The electromagnetic wires pass around the winding support rods 14 of each mounting ring 15 from the inside to the outside along the innermost mounting ring 15. A heat dissipation gap is left between two adjacent electromagnetic wire layers 19.

[0025] In this embodiment, the transmission mechanism 2 drives the conveying mechanism 7 to move, and the magnetic separation mechanism 5 can adsorb the magnetic material in the material below the conveying mechanism 7 onto the conveying mechanism 7, and under the drive of the conveying mechanism 7, the magnetic material is transported to the target position.

[0026] The housing 13 is connected to the frame 8 by a detachable connection mechanism, which facilitates the disassembly of the magnetic separation mechanism 5 and makes it easier to carry out the maintenance process of the device.

[0027] An electromagnetic wire is wound starting from the innermost mounting ring 15 and around all the innermost winding support rods 14 to a certain thickness. Then, it is pulled towards the adjacent outer mounting ring 15 and wound around the winding support rods 14 on the adjacent outer mounting ring 15. The winding continues outward in sequence. After the winding is completed, each mounting rod on the mounting ring 15 has a layer of electromagnetic wire wound around it. The gap between two adjacent layers of electromagnetic wire is conducive to air circulation, which can dissipate heat more quickly, making the heat dissipation of the electromagnetic wire better, ensuring that the performance of the magnetic separation mechanism 5 is maintained well, and ensuring the normal operation of the device.

[0028] An oil cooling mechanism is installed on the housing 13, which can cool the inside of the housing 13 and control the temperature inside the housing 13.

[0029] The oil cooling mechanism includes a coil 18, which is fixedly connected to the inner wall of the winding drum 17. Both ends of the coil 18 pass through the side wall of the housing 13 and are connected to an oil cooler 12. The oil cooler 12 is fixedly connected to the top of the housing 13. The coil 18 is filled with cooling oil. The air in the housing 13 exchanges heat with the coil 18, causing the temperature inside the housing to drop and the oil temperature in the coil 18 to rise. The heated oil passes through the coil 18 and enters the oil cooler 12 for cooling. After cooling, the oil returns to the coil 18 to continuously cool the housing 13. The oil temperature can be controlled by controlling the working efficiency of the oil cooler 12, thereby achieving accurate control of the temperature inside the housing 13.

[0030] The top of the housing 13 is provided with a vent 11, which is connected to the winding drum 17. A fan 10 is installed inside the vent 11. The vent can accelerate the air flow inside the housing 13, which helps to control the temperature inside the housing 13. The speed of the fan 10 can be adjusted according to the actual situation to control the air flow speed and thus control the temperature inside the housing 13.

[0031] A temperature sensor is installed inside the housing 13. The temperature sensor is electrically connected to a controller. The controller is electrically connected to the oil cooler 12 and the fan 10. The temperature sensor can detect the temperature inside the housing 13 and adjust the fan 10 and the oil cooler 12 according to the measured temperature, thereby controlling the temperature inside the housing 13 to be maintained within a suitable temperature range.

[0032] The conveying mechanism 7 includes at least two conveying rollers 4, which are rotatably connected to the frame 8 and connected to each other by a belt 6.

[0033] The transmission mechanism 2 includes a motor 1, which is fixedly connected to the frame 8. A second sprocket is fixedly connected to the output end of the motor 1. A first sprocket that cooperates with the second sprocket is installed at one end of a conveying roller 4. The first sprocket and the second sprocket are connected by a chain. A protective cover 3 that cooperates with the first sprocket and the second sprocket is installed on the frame 8. The protective cover 3 serves to protect the first sprocket and the second sprocket during normal operation and to prevent dust.

[0034] Motor 1 drives the second sprocket to rotate, and the second sprocket drives the first chain to rotate via a chain. The first sprocket drives the connected conveyor roller 4 to rotate, and can also drive other conveyor rollers 4 to rotate synchronously via belt 6. Belt 6 completes the conveying of the magnetic material adsorbed by the magnetic separation mechanism 5.

[0035] The detachable connection mechanism includes a lifting lug 9 and a connecting ring. The lifting lug 9 is fixedly connected to the housing 13, and the connecting ring is fixedly connected to the frame 8. The lifting lug 9 and the connecting ring are connected by a hook. The structure is simple and easy to disassemble, which facilitates the maintenance of the magnetic separation mechanism 5.

[0036] In summary, during actual use, the magnetic separator 5 screens the material below the belt 6. Magnetic materials are attracted to the area below the belt 6 and move along with it. When the material is transported outside the magnetic range of the magnetic separator 5, it falls naturally off the belt 6, completing the screening process. During screening, the magnetic separator 5 dissipates heat through the gaps between the electromagnetic wires. If the temperature of the magnetic separator 5 is too high and the screening process cannot be completed normally, the fan 10 is turned on to increase the airflow speed inside the housing 13, thus accelerating the heat exchange of the magnetic separator 5. If the temperature inside the magnetic separator 5 still cannot be controlled within a suitable range, the oil cooler 12 is turned on to exchange heat between the oil in the coil 18 and the air inside the housing 13, maintaining the temperature inside the magnetic separator 5 within a suitable range and ensuring the normal operation of the device.

[0037] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
