Description

Technical Field

[0001] The present invention relates to the technical field of magnet processing, and specifically discloses a rapid cooling hydrogen breaking device for magnet processing. Background Art

[0002] During the magnet processing, hydrogen breaking is an important process. The commonly used equipment is a rotary hydrogen breaking furnace, which is a device for manufacturing rare earth permanent magnet alloy powder by hydrogen explosion fragmentation process. Its principle is to utilize the characteristics of grain boundary fracture and transgranular fracture generated by the rare earth permanent magnet alloy itself during the hydrogen absorption and desorption processes to cause alloy pulverization, thereby obtaining alloy powder with a certain particle size. When the material is completed with hydrogen breaking, it is necessary to cool the material to room temperature and then discharge and collect it. In the prior art, when cooling the material in the hydrogen breaking furnace, the external spray water cooling method is generally adopted. However, during the spraying process, since the hydrogen breaking furnace is in a rotating state, the cooling water will be thrown out, and the cooling effect is limited.

[0003] After retrieval, a hydrogen breaking furnace with the publication number of CN108907206A includes a frame, a furnace body, a heating device and a cooling device; by setting a horizontal guide rail and a first heating outer shell and a second heating outer shell slidably connected along the horizontal guide rail, the heating device is respectively arranged in the first heating outer shell and the second heating outer shell. Water is sprayed downward through a first water spray pipe arranged above the furnace body, and water is sprayed upward through a second water spray pipe arranged below the furnace body, so that the furnace body can be quickly cooled. By using the self-rotation of the furnace body, the cooling water is evenly distributed on the outer surface of the furnace body, and the cooling water can be collected through a semi-circular groove and reused; the furnace body is heated from the outside by a separable heating outer shell, and combined with the water spraying cooling device arranged below, the rapid heating and cooling of the hydrogen breaking furnace are realized. Compared with the traditional inner heating furnace body, the cooling efficiency is greatly improved, and the working hours of the hydrogen breaking process are shortened.

[0004] Based on the above retrieval and combined with the prior art, it is found that the prior art adopts the method of upper and lower spraying for the cooling operation of the hydrogen breaking furnace. However, when the sprayed cooling water contacts the hydrogen breaking furnace, it is easily thrown out by the rotating hydrogen breaking furnace, resulting in a short contact time between the cooling water and the hydrogen breaking furnace, limited cooling effect, and the diffused high-temperature hot gas will leak during the expansion of the heating device and the spraying cooling process, which is prone to safety hazards. Therefore, a rapid cooling hydrogen breaking device for magnet processing is proposed to improve the above problems. Summary of the Invention

[0005] Aiming at the above prior art, the technical problem to be solved by the present invention is that the sprayed cooling water is easily thrown out by the rotating hydrogen breaking furnace when contacting the hydrogen breaking furnace, resulting in a short contact time between the cooling water and the hydrogen breaking furnace, limited cooling effect, and the diffused high-temperature hot gas will leak, which is prone to safety hazards.

[0016] In summary, after adopting the above structure, compared with the prior art, the present invention has the following advantages:

[0017] 1. The reciprocating unfolding component provided in the present invention can drive the heating cover and the cooling cover to move in opposite directions, quickly realizing the switching function of the hydrogen breaking furnace from heating to cooling. In the hydrogen breaking process, the rapid switching function can meet the process requirements of different stages, avoiding affecting the product quality due to untimely temperature change.

[0018] 2. The rotation mechanism provided by the present invention drives the hydrogen breaking furnace to rotate. At the same time, the stirring blades installed at the bottom of the hydrogen inlet pipe can stir the materials in the furnace when hydrogen is introduced. The combination of rotation and stirring enables the materials to come into full contact with hydrogen, improving the uniformity and efficiency of the hydrogen breaking reaction and ensuring the stability of product quality.

[0019] 3. After the reciprocating unfolding assembly drives the cooling cover to close, the present invention can spray cold water on the surface of the hydrogen breaking furnace under the action of the spraying mechanism and the refrigerator, and make the water accumulate at the bottom of the two cooling covers and surround the bottom of the hydrogen breaking furnace. Thus, the hydrogen breaking furnace can be quickly cooled in an approximately closed environment, shortening the cycle of the entire hydrogen breaking process. Compared with the traditional cooling method, it can prevent the water from being thrown out by the rotating hydrogen breaking furnace, increase the contact time between the cooling water and the hydrogen breaking furnace, fully improve the cooling effect, and greatly improve the production efficiency, enabling the equipment to process more materials per unit time.

[0020] 4. When the reciprocating unfolding assembly drives the cooling cover to unfold, the present invention can return the water along the tray and the first return pipe to the water tank, realizing the function of recycling water, reducing the consumption of the coolant, and lowering the production cost.

[0021] 5. The hot gas concentration assembly provided by the present invention can collect the hot gas during the unfolding and cooling processes of the heating cover and transport it through the air extractor, enabling the hot gas to flow in the variable diameter channels of the thick pipe, the variable diameter pipe, and the thin pipe. This increases the heat conduction rate between the hot gas and the external environment, causing the water in the collected hot gas to form droplets in the pipeline and then return to the water tank for recycling, fully improving the function of water recycling, further reducing the operating cost of the equipment, and then discharging the cooled hot gas to the outside to avoid the problem of potential safety hazards caused by the leakage of the diffused high-temperature hot gas.

A water tank 5 is installed at the bottom of the frame 1, and a refrigerator 13 is installed on one side of the top of the water tank 5.

A three-way joint 802 is installed on the drain pipe of the circulating pump 801. Both ends of the three-way joint 802 are fixedly installed with corrugated pipes 803. One end of each of the two corrugated pipes 803 is fixedly installed with a spray pipe 804 inserted into the cooling cover 7. Nozzles 805 are installed on the side of the spray pipe 804 facing the hydrogen breaking furnace 11 at equal intervals. Closing grooves 21 are respectively arranged at the middle positions of the top and bottom of one side of the heating cover 2 and the middle positions of the top and bottom of one side of the cooling cover 7, and sealing sleeves 23 are installed on the inner walls of the closing grooves 21.Two adjacent sealing sleeves 23 are attached to the surface of the hydrogen breaking furnace 11. By using the reciprocating unfolding assembly 9 and the spraying mechanism 8 described above, the heating hood 2 and the cooling hood 7 can be driven to move in opposite directions, quickly realizing the switching function of the hydrogen breaking furnace 11 from heating to cooling. And through the action of the spraying mechanism 8 and the refrigerating machine 13, cold water is sprayed on the surface of the hydrogen breaking furnace 11, so that water accumulates at the bottom of the two cooling hoods 7 and surrounds the bottom of the hydrogen breaking furnace 11, thereby enabling the hydrogen breaking furnace 11 to be quickly cooled in an approximately closed environment, shortening the cycle of the entire hydrogen breaking process.

[0039] In the present invention, a hydrogen inlet pipe 19 inserted into the central position of the hydrogen breaking furnace 11 is fixed on the installation square frame 901, and the outer wall of the hydrogen inlet pipe 19 is rotatably connected to the top inner wall of the hydrogen breaking furnace 11 through a shaft seal. A stirring blade 20 is installed at the bottom of the hydrogen inlet pipe 19. A feed hopper 18 is fixed on one side of the top of the hydrogen breaking furnace 11, and a sealing cover is provided at the top of the feed hopper 18. A discharge valve is installed at the bottom of the hydrogen breaking furnace 11.

[0040] In the present invention, the rotating mechanism 15 includes a driven gear 1502 fixedly installed at the bottom outer wall of the hydrogen breaking furnace 11, and a rotating motor 1503 is fixedly installed at the bottom of the support frame 12. A second driving gear 1501 meshing with the driven gear 1502 is fixedly installed on the output shaft of the rotating motor 1503, as Figures 2-5 shown. By using the rotating mechanism 15 described above, it is convenient to drive the hydrogen breaking furnace 11 to rotate, and cooperate with the stirring blade 20 to stir the materials in the furnace when hydrogen is introduced, so that the materials are fully contacted with hydrogen, improving the uniformity and efficiency of the hydrogen breaking reaction.

[0041] In the present invention, a tray 4 located directly below the hydrogen breaking furnace 11 is installed on one side of the top of the water tank 5, and a first return pipe 14 evenly distributed is fixed on one side of the tray 4. The first return pipe 14 connects the inside of the tray 4 and the inside of the water tank 5. First one-way valves are installed on all the first return pipes 14, as Figure 2 and Figure 6 shown. By using the tray 4 and the first return pipe 14 described above, the cooled coolant is returned to the water tank 5 through the tray 4 and the first return pipe 14, realizing the recycling of the coolant.

[0042] In the present invention, sealing grooves 22 are provided around the four sides of one side of one heating hood 2 and around the four sides of one side of one cooling hood 7, and sealing strips 24 fitting in the sealing grooves 22 are fixed around the four sides of one side of the other heating hood 2 and around the four sides of one side of the other cooling hood 7, as Figure 7 and Figure 8 shown.

The controller 3 automatically adjusts the flow rate of the circulation pump 801 and the refrigerating capacity of the refrigerator 13 according to the preset temperature parameters. When the temperature reaches the preset value, the whole device is controlled to stop.

[0044] The second embodiment:

[0045] Based on the first embodiment, the following structure is added in this embodiment, so that the present application has the function of preventing the leakage of high-temperature hot gas from spreading. The specific settings are as follows: A hot gas concentration component 10 is arranged at the middle position of the top of the frame 1, and the hot gas concentration component 10 includes a gas collecting cover 1001. An air extractor 1002 is installed at the middle position of the top of the gas collecting cover 1001. A thick pipe 1003 is installed at the exhaust end of the air extractor 1002. A plurality of intersecting reduced-diameter pipes 1004 and thin pipes 1005 are fixed at the bottom end of the thick pipe 1003. The reduced-diameter pipes 1004 are designed to be thin-walled. A second return pipe 1006 communicating with the inside of the water tank 5 is fixed at the bottom end of the thin pipe 1005 at the bottom. An exhaust pipe 1007 passing through the water tank 5 is fixed on one side of the second return pipe 1006. A second one-way valve is installed at the bottom of the second return pipe 1006. Exhaust holes 1008 are arranged at equal distances in a ring shape at the top of the two cooling covers 7. The controller 3 is electrically connected to the air extractor 1002. As Figure 1 、 Figure 2 、 Figure 8 and Figure 9 shown, by using the above hot gas concentration component 10, the hot gas during the unfolding and cooling of the heating cover 2 can be collected and transported by the air extractor 1002. After the hot gas passes through the thick pipe 1003, the reduced-diameter pipes 1004 and the thin pipes 1005, the water vapor in the hot gas is cooled and liquefied in the reduced-diameter pipes 1004 and the thin pipes 1005, and the liquid flows back to the water tank 5 through the second return pipe 1006, while the non-condensable gas is discharged through the exhaust pipe 1007, so that the water in the collected hot gas can be recycled, and then the hot gas is cooled and discharged to the outside, avoiding the problem of potential safety hazards caused by the leakage of high-temperature hot gas that spreads.

[0046] In summary, the working principle of the present invention is as follows: Open the sealing cover at the top of the feed hopper 18, add the magnet raw materials to be processed into the hydrogen breaking furnace 11 through the feed hopper 18, then close the sealing cover. Next, start the positive and reverse motor 902 in the reciprocating unfolding assembly 9. The first driving gear 910 on its output shaft rotates, driving the meshing driving bevel gear 904 to rotate. The driving bevel gear 904 drives the first threaded rod 903 and the second threaded rod 905 to rotate through the driven bevel gear 911, causing the two first movable plates 907 and the two heating covers 2 to approach each other. At this time, hydrogen is introduced into the hydrogen breaking furnace 11 through the hydrogen inlet pipe 19, and the hydrogen breaking furnace 11 is heated through the heating cover 2. The rotation motor 1503 in the rotation mechanism 15 drives the second driving gear 1501 to rotate, which meshes with the driven gear 1502, thereby driving the hydrogen breaking furnace 11 to rotate, making the material heat more evenly and accelerating the hydrogen breaking reaction. At the same time, with the action of the stirring blades 20, the raw materials in the furnace are stirred, enabling the material to fully contact with hydrogen, thereby carrying out the hydrogen breaking reaction;

[0047] When the hydrogen breaking reaction is completed, start the positive and reverse motor 902 again to reverse it. Similarly, through the transmission of gears and threaded rods, the heating cover 2 moves away from the hydrogen breaking furnace 11, and the cooling cover 7 approaches the hydrogen breaking furnace 11 until the adjacent two sealing sleeves 23 and the cooling cover 7 are attached to the surface of the hydrogen breaking furnace 11. During this process, start the air extractor 1002 in the hot gas concentrating assembly 10 to extract the hot gas into the gas collecting hood 1001. After passing through the thick pipe 1003, the reducing pipe 1004, and the thin pipe 1005, the water vapor in the hot gas is cooled and liquefied in the reducing pipe 1004 and the thin pipe 1005. The liquid flows back to the water tank 5 through the second return pipe 1006, and the non-condensable gas is discharged through the exhaust pipe 1007;

[0048] After the cooling cover 7 is closed, start the circulation pump 801 to extract the coolant cooled by the refrigerator 13 in the water tank 5. The coolant is divided into two bellows 803 through the three-way pipe 802, then enters the spray pipe 804, and finally is sprayed on the surface of the hydrogen breaking furnace 11 through the spray head 805 to take away the heat and achieve rapid cooling. Moreover, during the cooling process, the rotation mechanism 15 continues to drive the hydrogen breaking furnace 11 to rotate, enabling the coolant to act evenly on the surface of the furnace body, improving the cooling effect, and also causing water to accumulate at the bottom of the two cooling covers 7 and surrounding the bottom of the hydrogen breaking furnace 11, so as to rapidly cool the hydrogen breaking furnace 11 in an approximately closed environment. Continue to process the hot gas during the cooling process through the hot gas concentrating assembly 10, and simultaneously monitor the temperature in the cooling cover 7 in real time through the temperature sensor 6 and transmit the temperature signal to the controller 3. The controller 3 automatically adjusts the flow rate of the circulation pump 801 and the refrigerating capacity of the refrigerator 13 according to the preset temperature parameters;

[0049] After the material is cooled to an appropriate temperature, the forward and reverse motor 902 is started again. Similarly, through the transmission of the gear and the threaded rod, the heating cover 2 and the cooling cover 7 are moved to appropriate positions, so that the coolant in the cooling cover 7 flows into the lower tray 4, and then flows back to the water tank 5 through the first return pipe 14 to realize the recycling of the coolant. After the coolant has flowed out, the discharge valve at the bottom of the hydrogen breaking furnace 11 is opened to discharge the processed magnet material, completing the entire processing process.

[0050] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the protection scope is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
