DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The utility model provides a technical solution: Figure 1-4 The utility model discloses a NdFeB waste crushing device, comprising a storage barrel 1, a crushing mechanism 2 is arranged inside the storage barrel 1, the crushing mechanism 2 comprises a grinding block 21 and a plurality of cutters 24, the grinding block 21 is arranged in the storage barrel 1, a rotating shaft 22 is fixedly installed at the center position of the top side of the grinding block 21, a driving member 23 is fixedly installed on the top side of the storage barrel 1, and the top of the rotating shaft 22 penetrates the barrel wall of the storage barrel 1 and is rotatably connected to the barrel wall of the storage barrel 1, the top of the rotating shaft 22 is fixedly connected to the driving end of the driving member 23, a plurality of cutters 24 are arranged on the top side of the grinding block 21 in a circular array, and one end of the cutter 24 is fixedly connected to the outer peripheral wall of the rotating shaft 22, and a cleaning mechanism 3 is commonly provided on the bottom side of the storage barrel 1 and the outer peripheral side of the storage barrel 1.

[0022] In this embodiment, the modified NdFeB waste crushing device, the cleaning mechanism 3 continuously injects water into the storage barrel 1, so that more water is stored in the water storage barrel, and at the same time, the driving member 23 drives the cutter 24 located on the grinding block 21 to rotate slowly through the rotating shaft 22, continuously stirring the NdFeB waste and the water in the storage barrel 1, thereby completing the cleaning operation of the NdFeB waste;

[0023] After the cleaning operation of the NdFeB waste is completed, the driving member 23 drives the cutter 24 and the grinding block 21 to rotate rapidly through the rotating shaft 22, and the rotating cutter 24 breaks the NdFeB waste. At the same time, the water pump 31 continues to inject water into the storage barrel 1, so that less water is stored in the storage barrel 1, and a water flow from top to bottom is formed in the storage barrel 1. The crushed NdFeB waste of appropriate size is pushed into the gap between the grinding block 21 and the inner wall of the storage barrel 1. The rotating grinding block 21 can further grind the crushed NdFeB waste and grind the NdFeB waste into fine particles. At the same time, the water in the storage barrel 1 can continue to cool the cutter 24 and the grinding block 21.

[0024] In a further preferred embodiment of the present invention, Figure 1 and Figure 2As shown, a feed hopper 4 is provided on the outer peripheral side of the top of the storage barrel 1, and a discharge end of the feed hopper 4 penetrates the wall of the storage barrel 1 and is fixedly connected to the wall of the storage barrel 1, and a plurality of telescopic supporting legs 5 are relatively fixedly installed on the outer peripheral side of the bottom of the storage barrel 1.

[0025] In this embodiment, when installing and disassembling the fixed barrel 33, the height of the storage barrel 1 can be adjusted by telescopic supporting legs 5, thereby adjusting the distance between the storage barrel 1 and the ground, making room for placing the fixed barrel 33 into the bottom side of the storage barrel 1 or taking the fixed barrel 33 out from the bottom side of the storage barrel 1.

[0026] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the grinding block 21 is arranged in a truncated cone shape, and the outer peripheral wall of the grinding block 21 is gap-matched with the inner wall of the storage barrel 1;

[0027] In this embodiment, the grinding block 21 is arranged in a truncated cone shape, so that each part of the grinding block 21 can be used for grinding NdFeB waste of different sizes, and the gap between the grinding block 21 and the inner wall of the storage barrel 1 is matched. The setting of the grinding block 21 will not affect the discharge of sewage in the storage barrel 1 and can intercept the NdFeB waste in the storage barrel 1.

[0028] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the cross-section of the cutter 24 is in a rhombus shape, and the other end of the cutter 24 contacts the inner peripheral wall of the storage barrel 1, and the bottom side of the cutter 24 contacts the top side of the grinding block 21;

[0029] In this embodiment, the cutter 24 with a diamond-shaped cross section has multiple blades, which can better break up the NdFeB waste.

[0030] In a further preferred embodiment of the present invention, Figure 2 As shown, the cleaning mechanism 3 includes a water pump 31, which is fixedly mounted on the top of the material storage barrel 1, and the water discharge end of the water pump 31 penetrates the barrel wall of the material storage barrel 1 and is fixedly connected to the barrel wall of the material storage barrel 1, and the water inlet end of the water pump 31 is connected to a soft pipe 32;

[0031] In this embodiment, when the above-mentioned NdFeB waste cleaning operation is performed, the water pump 31 draws water to the top of the storage barrel 1 through the soft tube 32 and sprinkles it, and then discharges the water from the storage barrel 1 from the opening at the bottom end of the storage barrel 1, thereby forming a water flow from top to bottom in the storage barrel 1, bringing dust out of the storage barrel 1, and applying a downward thrust to the crushed small-particle NdFeB waste through the push of the water flow, so that the crushed NdFeB waste can quickly enter the gap between the grinding block 21 and the inner wall of the storage barrel 1 for NdFeB waste grinding processing.

[0032] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, a fixed cylinder 33 is provided at the bottom end of the storage cylinder 1, and an interface 34 is provided on the outer peripheral side of the top of the fixed cylinder 33, and the interface 34 penetrates the cylinder wall of the fixed cylinder 33 and is fixedly connected to the cylinder wall of the fixed cylinder 33, and the bottom end of the soft pipe 32 is connected and installed with the drainage end of the interface 34;

[0033] In this embodiment, the water discharged from the discharge end of the storage barrel 1 directly falls into the fixed barrel 33, and the water pump 31 absorbs the water discharged from the storage barrel 1 from the top of the fixed barrel 33 through the soft pipe 32, thereby forming a circulating water flow in the storage barrel 1 and the fixed barrel 33, reducing the water loss during the operation of the device;

[0034] It should be noted that a sealing ring is installed on the outer peripheral side of the top of the rotating shaft 22 to seal the gap between the rotating shaft 22 and the wall of the storage barrel 1.

[0035] In a further preferred embodiment of the present invention, Figure 4 As shown, the fixing cylinder 33 is internally threaded with a filter plate 35 in an annular shape, and the discharge end of the storage cylinder 1 passes through the inner hole of the filter plate 35 and contacts the inner hole of the filter plate 35, and a plurality of fixing blocks 36 are fixedly installed on the top side of the filter plate 35 in a circumferential array;

[0036] In this embodiment, the water discharged from the discharge end of the storage barrel 1 directly falls below the filter plate 35, and then the filter plate 35 intercepts impurities such as dust in the water or crushed NdFeB waste and stores them in the fixed barrel 33, so that the water pump 31 only absorbs cleaner water through the soft pipe 32.

[0037] Working principle: When crushing NdFeB waste, the operator first starts the telescopic support leg 5 and lifts the storage barrel 1 upwards. Then the operator places the fixed barrel 33 below the discharge end of the storage hopper. Then the operator inserts the filter plate 35 into the storage barrel 1 and pushes the filter plate 35 through the fixed block 36 to screw the filter plate 35 into the fixed barrel 33. The position of the filter plate 35 in the fixed barrel 33 is adjusted. Then the telescopic support leg 5 is retracted so that the discharge end of the storage barrel 1 is inserted through the hole of the filter plate 35 and moves to the bottom of the filter plate 35. Finally, the bottom end opening of the soft tube 32 is connected to the interface 34. The assembly of the device is completed.

[0038] After the device is assembled, water is continuously injected into the water storage cylinder from the top opening of the fixed cylinder 33 until the water flows through the holes of the filter plate 35 and overflows the interface 34. At the same time, the driving member 23 and the water pump 31 are started, and the water pump 31 continuously pumps the water in the fixed cylinder 33 into the storage cylinder 1. Since the gap between the grinding block 21 and the inner wall of the storage cylinder 1 is small, the water injected into the storage cylinder 1 slowly passes through the gap between the grinding block 21 and the storage cylinder 1. Finally, the sewage is discharged from the discharge end of the storage cylinder 1 into the fixed cylinder 33. At the same time, the driving member 23 drives the cutter 24 to rotate slowly through the rotating shaft 22. The rotating cutter 24 continuously moves the water in the storage cylinder 1 and the NdFeB waste in the storage cylinder 1, thereby completing the NdFeB waste cleaning operation;

[0039] It should be noted that when the water pump 31 pumps the water in the fixed cylinder 33 into the storage cylinder 1, the operator needs to continuously inject water into the fixed cylinder 33 from the top opening of the fixed cylinder 33 so that the water in the fixed cylinder 33 always overflows the interface 34.

[0040] It should be noted that after the sewage is discharged into the fixed cylinder 33, due to the obstruction of the filter plate 35, the impurities in the sewage are trapped and stored in the fixed cylinder 33, so that the water pump 31 always draws relatively clean water from the fixed cylinder 33 through the soft pipe 32 and the interface 34;

[0041] After the NdFeB waste is cleaned, the operation of the water pump 31 is stopped, and the relatively clean water in the storage barrel 1 is gradually discharged from the discharge end of the storage barrel 1 into the fixed barrel 33, and the excess water in the fixed barrel 33 overflows from the top opening of the fixed barrel 33 and is discharged to the outside. Then the operator lifts the storage barrel 1 as described above, and releases the connection between the soft tube 32 and the interface 34, and then moves the fixed barrel 33 out from the bottom of the storage barrel 1, and rotates the filter plate 35 through the fixed block 36 to screw the filter plate 35 out of the fixed barrel 33, and then the operator moves the fixed barrel 33 to move the sewage containing more dust to a specific position for dumping;

[0042] Then the operator reassembles the device according to the above, and then the operator injects an appropriate amount of water into the fixed cylinder 33 according to the above, and the water pump 31 slowly extracts the water in the fixed cylinder 33 through the soft tube 32 and the interface 34, so that there is always less water on the top of the grinding block 21, and at the same time the driving member 23 starts to quickly drive the cutter 24 to rotate through the rotating shaft 22, and the fast rotating cutter 24 breaks the NdFeB waste into small pieces of NdFeB waste, and the above water flow can cut The knife 24 and the grinding block 21 are continuously cooled. The crushed NdFeB waste is pushed into the gap between the grinding block 21 and the storage barrel 1 by the water flow from top to bottom in the storage barrel 1. The rapidly rotating grinding block 21 can grind small pieces of NdFeB waste into fine particles, which are finally discharged into the fixed barrel 33 along with the water flow and intercepted by the filter plate 35 for storage in the fixed barrel 33.

[0043] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
