Description

Technical Field

[0001] The present application relates to the technical field of magnet production equipment, and in particular to a hydrogenation crushing furnace. Background Art

[0002] At present, NdFeB contains rare earth element neodymium and elements iron and boron. As a kind of rare earth permanent magnet material, NdFeB has extremely high magnetic energy product and coercive force. At the same time, the advantages of high energy density make NdFeB permanent magnet material widely used in modern industry and electronic technology. The methods for manufacturing NdFeB mainly adopt sintering method and bonding method. Among them, sintering method is widely used due to its high production efficiency and good quality. The main process of sintering method is batching, smelting, ingot casting, powder making, sintering and post-processing, etc. Since hydrogenation powder making is pollution-free and noise-free, hydrogenation powder making is mostly adopted for powder making, and hydrogenation powder making requires the use of hydrogenation crushing furnace.

[0003] The hydrogenation crushing furnace is a device that uses the hydrogen absorption characteristics of rare earth metal intermetallic compounds to place the NdFeB alloy in a hydrogen environment. The hydrogen enters the alloy along the Nd-rich phase thin layer, causing it to expand, burst and break, and crack along the Nd-rich phase layer, thereby turning the thin slices into coarse powder. The hydrogenation crushing furnace needs to be heated to 600°C during the production process. When the hydrogenation crushing furnace completes the hydrogenation crushing of the NdFeB alloy, the furnace body needs to be cooled down, and the product in the furnace can be taken out after cooling down.

[0004] In the prior art, most hydrogen crushing furnaces include a frame, a furnace arranged on the frame, a heating furnace for heating the furnace, and a cooling device for cooling the furnace. The cooling device includes a water spraying pipe arranged on the frame and placed above the furnace, and a water collecting tank connected to the bottom of the furnace and used to recover the coolant.

[0005] With regard to the above-mentioned related technologies, the water spray pipes are mostly directly fixed on the frame and cannot be disassembled. When the water spray pipes are damaged, it is inconvenient to disassemble and replace the water spray pipes for repair, so there is room for improvement. Utility Model Content

[0006] In order to facilitate the removal and replacement of the water spray pipe, the present application provides a hydrogenation crushing furnace.

[0007] The present application provides a hydrogenation crushing furnace adopting the following technical solution:

[0008] A hydrogenation crushing furnace comprises a frame, a crushing furnace body and a cooling assembly, wherein the crushing furnace body is rotatably connected to the frame, and the cooling assembly is arranged on the frame and used to cool the crushing furnace body;

[0009] The cooling assembly includes a frame body, a support rod, a water spraying pipe, a pressing block and a water collecting tank. The frame body is connected to the machine frame. The support rod is arranged on the frame body and is used to support the water spraying pipe. The water spraying pipe is detachably connected to the support rod. The water spraying pipe is located above the main body of the crushing furnace and is provided with a plurality of nozzles along its own length direction. Each nozzle is used to spray a coolant onto the main body of the crushing furnace. The pressing block locks the water spraying pipe to the support rod through a fastener. The water collecting tank is located below the main body of the crushing furnace and is used to collect the coolant sprayed out by the water spraying pipe.

[0010] By adopting the above technical solution, the water in the water spraying pipe is sprayed onto the outer surface of the main body of the crushing furnace through the nozzles, and the cooling water takes away the heat of the main body of the crushing furnace, thereby achieving temperature reduction. The water collecting tank can collect the cooling water spilled from the main body of the crushing furnace, reduce waste and improve the utilization rate of the cooling water.

[0011] When a failure occurs in the water spraying pipe, the staff can loosen the fastener, the pressing block can be removed from the water spraying pipe, and then the water spraying pipe can be removed and repaired, so as to facilitate the disassembly and replacement of the water spraying pipe.

[0012] Preferably, a first limiting groove is formed on the support rod, and the first limiting groove is used to limit the water spraying pipe. A second limiting groove is formed on one side of the pressing block facing the support rod, and the second limiting groove corresponds to the first limiting groove up and down. When the pressing block is locked to the support rod, the water spraying pipe is located between the first limiting groove and the second limiting groove.

[0013] By adopting the above technical solution, the first limiting groove and the second limiting groove can play a role in limiting the water spraying pipe, reducing the possibility of the position of the water spraying pipe shifting.

[0014] Preferably, a plurality of the first limiting grooves are arranged at intervals along the length direction of the support rod, and a plurality of the second limiting grooves are also arranged at intervals. Each of the second limiting grooves corresponds to each of the first limiting grooves respectively.

[0015] By adopting the above technical solution, the existence of a plurality of first limiting grooves can facilitate the clamping of the water spraying pipe at different positions of the support rod, and then change the relative position between the water spraying pipe and the main body of the crushing furnace, which is convenient for the staff to reasonably select according to actual needs and improves the practicability.

[0016] Preferably, a driving member is further included. The support rod is slidably arranged on the frame body in the vertical direction. The driving member is connected to the support rod and is used to control the movement of the support rod.

[0017] By adopting the above technical solution, the driving member can control the vertical movement of the support rod, thereby changing the distance between the water spraying pipe and the main body of the crushing furnace. By reasonably controlling the distance between the two, the situation that the cooling liquid splashes out due to the water spraying head being too close or too far from the main body of the crushing furnace can be reduced.

[0018] Preferably, a guide wheel is rotatably connected to the support rod, a guide groove for the movement of the guide wheel is formed on the frame body, and the guide wheel rolls in the guide groove.

[0019] By adopting the above technical solution, the guide wheel is connected to the guide groove in a rolling manner, realizing rolling friction and reducing the friction force suffered by the support rod during movement. At the same time, the mutual cooperation between the guide wheel and the guide groove can improve the stability of the support rod during movement.

[0020] Preferably, it further includes a water inlet pipe and a hoop. The water inlet pipe is a flexible pipe and is detachably connected to the water spraying pipe. The water inlet pipe is communicated with the water collecting tank; one end of the water spraying pipe is sleeved on the water inlet pipe, and the connection between the water spraying pipe and the water inlet pipe is fixed by the hoop.

[0021] By adopting the above technical solution, the cooling liquid in the water collecting tank can flow into the water spraying pipe through the water inlet pipe under the action of the pump, realizing the recycling of the cooling liquid. At the same time, the hoop tightly connects the water spraying pipe and the water inlet pipe together. When the water spraying pipe needs to be disassembled, the hoop can be loosened, and then the water spraying pipe can be removed from the water inlet pipe by applying force.

[0022] Preferably, it further includes a guide plate. The guide plate is arranged in the water collecting tank and is inclined on the frame. The guide plate is used to guide the water droplets on the main body of the crushing furnace.

[0023] By adopting the above technical solution, the guide plate can fully introduce the water droplets dripping from the main body of the crushing furnace into the water collecting tank, reducing the probability of coolant loss.

[0024] Preferably, it further includes a scissor lift. The water collecting tank is connected to the scissor lift, and the scissor lift is used to control the vertical movement of the water collecting tank.

[0025] By adopting the above technical solution, the scissor lift can drive the water collecting tank to move up and down, thereby changing the distance between the water collecting tank and the main body of the crushing furnace, so as to adjust the water collecting tank to a suitable height and reduce the interference with the rotation of the main body of the crushing furnace.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0037] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples shown in the present application.

[0038] The present application embodiment discloses a hydrogenation crushing furnace. Figure 1 The hydrogenation crushing furnace comprises a frame 1, a crushing furnace body 2 and a cooling assembly 3. The frame 1 is fixedly installed on the ground as a supporting carrier. The crushing furnace body 2 is rotatably connected to the frame 1, and the cooling assembly 3 is installed on the frame 1 and is used to cool the crushing furnace body 2.

[0039] Combination Figure 2 Specifically, the cooling assembly 3 includes a frame 31, a support rod 32, a water spray pipe 33, a pressing block 34 and a water collecting box 35. The frame 31 is fixedly connected to the frame 1, and the support rod 32 is installed on the frame 31 and is used to support the water spray pipe 33. The water spray pipe 33 is arranged along the central axis direction of the crushing furnace body 2 and is detachably connected to the support rod 32. The water spray pipe 33 is located above the crushing furnace body 2, and is provided with a plurality of nozzles 4 along its length direction, and each nozzle 4 is used to spray the cooling liquid to the outer surface of the crushing furnace body 2. During cooling, the water in the water spray pipe 33 is sprayed onto the outer surface of the crushing furnace body 2 through the nozzle 4, and the cooling water takes away the heat of the crushing furnace body 2, thereby achieving cooling. The pressing block 34 locks the water spray pipe 33 on the support rod 32 through a fastener, and the fastener is a fastening bolt. The water collecting box 35 is located directly below the crushing furnace body 2 and is used to collect the cooling liquid sprayed from the water spray pipe 33. The water collecting box 35 can collect the cooling water spilled from the crushing furnace body 2, thereby reducing waste and improving the utilization rate of the cooling water.

[0040] When the watering pipe 33 fails, since the fastener is a detachable object, the staff can loosen the fastener to remove the pressing block 34 from the watering pipe 33, thereby facilitating the removal and maintenance of the watering pipe 33 and making it easy to replace the watering pipe 33.

[0041] Among them, a first limiting groove 5 is formed in the support rod 32. The first limiting groove 5 is arc-shaped and is used to limit the water spraying pipe 33. A second limiting groove 6 is formed in the side of the pressing block 34 facing the support rod 32. The second limiting groove 6 and the first limiting groove 5 are vertically corresponding. When the pressing block 34 presses the water spraying pipe 33 against the support rod 32, the water spraying pipe 33 is located between the first limiting groove 5 and the second limiting groove 6, thereby playing a role in limiting the water spraying pipe 33 and reducing the possibility of the position of the water spraying pipe 33 shifting. In this embodiment, a plurality of first limiting grooves 5 are provided, and the first limiting grooves 5 are spaced along the length direction of the support rod 32; the same number of second limiting grooves 6 as the first limiting grooves 5 are provided on the pressing block 34, and the second limiting grooves 6 and the first limiting grooves 5 correspond to each other respectively. The existence of a plurality of first limiting grooves 5 can facilitate the clamping of the water spraying pipe 33 at different positions on the support rod 32, thereby changing the relative position between the water spraying pipe 33 and the crushing furnace main body 2 and improving the practicability.

[0042] In some embodiments, the support rod 32 is movably arranged on the frame body 31 in the vertical direction. Guide wheels 7 are rotatably connected to both ends of the support rod 32. Guide grooves 8 for the guide wheels 7 to move are formed in the frame body 31. The guide grooves 8 are arranged along the moving direction of the support rod 32. The guide wheels 7 roll in the guide grooves 8 to achieve rolling friction and reduce the friction force received by the support rod 32 during movement. At the same time, the guide grooves 8 can also play a role in limiting and improve the stability of the support rod 32 during movement. Among them, a driving member 9 is further installed on the frame body 31. The driving member 9 is used to control the up and down movement of the support rod 32. The driving member 9 is a linear cylinder. The piston rod of the linear cylinder is connected to the support rod 32. When the piston rod expands and contracts, the support rod 32 can move up and down, thereby changing the distance between the water spraying pipe 33 and the crushing furnace main body 2. By reasonably controlling the distance between the two, the situation that the coolant splashes out due to the nozzle 4 being too close to or too far from the crushing furnace main body 2 is reduced.

[0043] Specifically, one end of the water spraying pipe 33 is closed and the other end is open, and the water spraying pipe 33 is detachably connected to the water inlet pipe 10. The water spraying pipe 33 is a hard pipe, and the water inlet pipe 10 is a flexible pipe and is communicated with the water collecting tank 35. The coolant in the water collecting tank 35 can flow into the water spraying pipe 33 through the water inlet pipe 10 under the action of a pump, realizing the recycling of the coolant. The water spraying pipe 33 is sleeved on the water inlet pipe 10, and the connection position between the water spraying pipe 33 and the water inlet pipe 10 is fixed together by a hoop 13. When it is necessary to disassemble the water spraying pipe 33, the hoop 13 can be loosened, and then the water spraying pipe 33 can be removed from the water inlet pipe 10 by applying force.

[0044] In addition, a scissor lift 11 is installed below the crushing furnace body 2, and the water collecting tank 35 is installed on the scissor lift 11. The scissor lift 11 is used to control the water collecting tank 35 to move in the vertical direction, thereby changing the distance between the water collecting tank 35 and the crushing furnace body 2, so as to adjust the water collecting tank 35 to a suitable height and reduce the interference with the rotation of the crushing furnace body 2. A guide plate 12 is also tiltedly arranged on the frame 1. The guide plate 12 is located below the crushing furnace body 2. The relatively lower end of the guide plate 12 is located in the water collecting tank 35. The guide plate 12 is used to guide the water drops on the crushing furnace body 2 into the water collecting tank 35 to reduce the probability of coolant loss.

[0045] The implementation principle of a hydrogenation crushing furnace in the embodiment of the present application is as follows: the water in the water spray pipe 33 is sprayed onto the outer surface of the crushing furnace body 2 through the nozzle 4, and the cooling water takes away the heat of the crushing furnace body 2, thereby achieving cooling. The water collecting box 35 can collect the cooling water spilled from the crushing furnace body 2, reduce waste, and achieve the recycling of cooling water. When the water spray pipe 33 fails, the staff can loosen the fastener, the pressing block 34 can be removed from the water spray pipe 33, and then the water spray pipe 33 can be disassembled and repaired, so that the water spray pipe 33 can be easily disassembled and replaced.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
