Description

Technical Field

[0001] The present application relates to the field of magnet preparation, and in particular to a purge device, a material conveying equipment and a control method thereof. Background Art

[0002] The hydrogen crushing process is an important process in the production process of NdFeB. The existing hydrogen explosion tank is movable. The hydrogen explosion tank is transported between the hydrogen explosion furnace, the cooling furnace and the loading and unloading platform to improve work efficiency.

[0003] However, when the hydrogen fragmentation reaction is completed, the main butterfly valve of the hydrogen explosion tank is closed. When the workers remove the connecting flange, a certain amount of hydrogenated powder will remain on the tank mouth flange. These powders will oxidize or even spontaneously combust when encountering air, wasting raw materials and making the separation operation dangerous.

[0004] For every batch (900kg) produced, 0.5-1.5kg of qualified hydrogenation powder will be wasted due to oxidation at the mouth of the hydrogenation tank.

[0085] like Figure 1 and Figure 2 As shown, the material tank 300 includes a tank body 310 and a butterfly valve 320, and the butterfly valve 320 is arranged at the tank mouth of the tank body 310. Optionally, the material tank 300 is a hydrogen explosion treatment tank, which is used to contain NdFeB alloy sheets, and the NdFeB alloy sheets are subjected to hydrogen explosion treatment in the tank. In the prior art, in order to facilitate the connection between the material tank 300 and the hydrogen explosion furnace, a tank mouth flange 200 is arranged at the end of the butterfly valve 320. After the hydrogen explosion treatment is completed, hydrogen explosion powder will remain on the tank mouth flange 200.

The docking flange 1 is locked and connected to the tank mouth flange 200 by a locking mechanism. After the hydrogen explosion treatment is completed, the docking flange 1 is separated from the tank mouth flange 200.

[0088] like Figure 6As shown, the adapter sleeve 2 can use an existing rotating adapter sleeve, and the adapter sleeve 2 includes a first outer sleeve 21 and a first inner sleeve 22. The first inner sleeve 22 is rotatably arranged on the first outer sleeve 21, and the second end 1b of the docking flange 1 penetrates the first inner sleeve 22.

The adapter sleeve 2 can deliver cooling water to the material tank 300.

[0089] like Figure 7 As shown, the gas circuit adapter 3 can use an existing gas circuit adapter. The gas circuit adapter 3 includes a second outer sleeve 31 and a second inner sleeve 32, and the second inner sleeve 32 is rotatably arranged in the second outer sleeve 31. The second inner sleeve 32 is provided with a second gas channel 33, and the second gas channel 33 is connected to the first gas channel 12. For example, the end of the second inner sleeve 32 is inserted into the first gas channel 12 so that the second gas channel 33 is connected to the first gas channel 12. The second outer sleeve 31 is provided with a first interface connected to the second gas channel 33, and the first interface flange 34 is arranged at the first interface, and the first interface flange 34 is connected to the hydrogen explosion furnace gas circuit through a pipeline.

[0090] The flange frame 5 is connected to the other end of the first hose 4. The first driver 6 is used to drive the flange frame 5 to move along the first direction. Figure 3 The X direction is the first direction, and the first direction is parallel to the axis of the docking flange 1. Optionally, the first driver 6 is disposed on the second outer sleeve 31 of the gas circuit adapter 3.

[0091] The purge air pipe 71 is arranged on the flange frame 5, and the purge air pipe 71 passes through the flange frame 5 and enters the first hose 4. The purge air pipe 71 is fixedly connected to the flange frame 5. The purge air pipe 71 passes through the first hose 4, the second air channel 33 and the first air channel 12 in sequence, and the end of the purge air pipe 71 extends into the air inlet 11. The flange frame 5 drives the purge air pipe 71 to move along the first direction, and the end of the purge air pipe 71 away from the air inlet 11 is connected to the air pump. The gas blown out of the purge air pipe 71 can purge the powder on the inner wall of the air inlet 11, and blow the residual powder into the tank body 310. When the air inlet 11 is purged, the tank body 310 continues to rotate, which is conducive to blowing away the residual powder.

[0092] When in use, the tank mouth flange 200 is connected to the material tank 300, the purge device 100 is moved to the docking flange 1 and enters the tank mouth flange 200, and the docking flange 1 and the tank mouth flange 200 are locked. The butterfly valve 320 is opened, and hydrogen is delivered to the tank body 310 through the first interface flange 34. At the same time, the material tank 300 rotates around its own axis, and the docking flange 1, the first inner sleeve 22 and the second inner sleeve 32 rotate around the axis with the material tank 300 to complete the hydrogen explosion treatment of NdFeB.

[0093] The air pump is started to deliver gas to the purge air pipe 71. Optionally, the gas blown out of the purge air pipe 71 is an inert gas. The first driver 6 drives the flange frame 5 and the purge air pipe 71 to reciprocate along the first direction. The gas blown out of the purge air pipe 71 purges the residual powder on the inner wall of the air inlet 11 and blows the residual powder into the tank body 310.

[0094] After the residual powder is blown back, the butterfly valve 320 is closed, and the docking flange 1 and the tank mouth flange 200 are unlocked and separated.

[0095] The docking flange 1 of the purging device 100 of this embodiment can be connected to the material tank 300, and the purging air pipe 71 blows the residual powder on the docking flange 1 and the residual powder at the port of the butterfly valve 320 back into the tank body 310, thereby improving the powder recovery rate in the hydrogen explosion treatment link and reducing the danger when the material tank is separated from the hydrogen explosion furnace.

The large-diameter port of the air inlet 11 is located at the end surface of the first end 1a of the docking flange 1, and the small-diameter port of the air inlet 11 is connected to the first air channel 12. The air inlet 11 is set to be trumpet-shaped, which facilitates the residual powder to slide down from the inner wall of the air inlet 11, thereby improving the efficiency of purging.

[0098] In some embodiments, the purge head 72 is adapted to the air inlet 11, and the purge head 72 is roughly truncated. The purge head 72 can close the small-diameter port of the air inlet 11. After the residual powder is blown back, the purge head 72 moves toward the direction close to the first air channel 12, and the purge head 72 closes the small-diameter port of the air inlet 11. After the purge device 100 is separated from the material tank 300, the purge head 72 can reduce the pollution of the environment to the first air channel 12.

The telescopic rod of the rotating cylinder 460 is hinged to the locking frame 410. The rotating cylinder 460 can drive the locking frame 410 to rotate. Optionally, the number of the rotating cylinders 460 is two, and the two rotating cylinders 460 are symmetrically arranged.

[0120] like Fig.21 As shown, the top surface of the second bracket 510 is arranged on a guide rail 5101 extending along the first direction, a slider 5102 is arranged on the guide rail 5101, and a slide plate 520 is arranged on the slider 5102 so that the slide plate 520 can slide along the first direction.

[0121] like Fig. 22As shown, the third bracket 530 is slidably disposed on the slide plate 520 along the second direction, and the second direction is the Z direction. A first guide post 5301 is disposed on the slide plate 520 , and the third bracket 530 is slidably disposed on the first guide post 5301 .

[0122] like Fig.23 As shown, the third bracket 530 is provided with a second guide column 5401 and a third guide column 5501 extending along the third direction, the third direction is the Y direction, and the first direction, the second direction and the third direction are perpendicular to each other. The first slider 540 is slidably disposed on the second guide column 5401, and the first slider 540 is connected to the adapter sleeve 2. The second slider 550 is slidably disposed on the third guide column 5501, and the second slider 550 is connected to the gas circuit adapter 3. The second driver 560 is disposed on the second bracket 510, and the second driver 560 is used to drive the purge device 100 to move along the first direction.

[0123] For example, the second driver 560 is a cylinder. The second driver 560 is connected to the third bracket 530 via the adapter 5302. The second driver 560 drives the purge device 100 to move along the first direction, so that the docking flange 1 can enter the tank flange 200, or move the docking flange 1 out of the tank flange 200.

[0124] The purging device 100 of this embodiment can move along the first direction, the second direction and the third direction, so as to facilitate the alignment of the tank mouth flange 200 and the docking flange 1 when they are connected.

[0125] The supporting mechanism 500 further includes: a first buffer structure 570 , a second buffer structure 580 and a third buffer structure 590 .

[0126] like Fig.24 As shown, the first buffer structure 570 is used to buffer the vibration of the purge device 100 along the first direction. For example, the first buffer structure 570 includes a fourth guide column 5701, and the fourth guide column 5701 is arranged at the output end of the second driver 560. The bottom end of the adapter 5302 is slidably arranged on the fourth guide column 5701, and first springs 5702 are arranged between both ends of the fourth guide column 5701 and the adapter 5302 to buffer the vibration of the adapter 5302 along the first direction.

[0127] like Fig. 22 As shown, the second buffer structure 580 is used to buffer the vibration of the purge device 100 along the second direction. For example, the second buffer structure 580 includes a second spring, and the second spring is disposed between the slide plate 520 and the third bracket 530 and between the third bracket 530 and the top of the first guide column 5301.

[0128] like Fig.23As shown, the third buffer structure 590 is used to buffer the vibration of the purge device 100 along the third direction. For example, the third buffer structure 590 includes a third spring, and the third spring is provided between the first slider 540 and the end of the second guide column 5401 and between the second slider 550 and the end of the third guide column 5501.

[0129] When the material tank 300 rotates, the purge device 100 will vibrate. The first buffer structure 570 , the second buffer structure 580 and the third buffer structure 590 are used to buffer the vibration of the purge device 100 to improve the safety of the purge device 100 .

[0130] When the material tank 300 rotates, the adapter sleeve 2 will inevitably produce tiny vibrations during the rotation process. Since each buffer structure is an elastic component, each elastic component also generates vibrations. The vibration of the rotating sleeve 2 and the vibration of the elastic component will affect the stable operation of the equipment. In order to reduce the possibility of interference between the two vibrations, the present application sets the length of the second spring of the second buffer structure 580 to 0.5 to 1.5 times the outer diameter of the adapter sleeve 2, the length of the first spring 5702 of the first buffer structure 570 is 1 to 2 times the outer diameter of the adapter sleeve 2, and the length of the third spring of the third buffer structure 590 is 0.1 to 0.5 times the outer diameter of the adapter sleeve 2. The stiffness coefficient of each spring is 50-200N / m.

[0131] This embodiment also provides a control method for the above-mentioned feeding device 10, the process includes:

[0132] The second driver 560 drives the purging device 100 to approach the material tank 300, and the docking flange 1 enters into the tank mouth flange 200. The rotating cylinder 460 drives the locking frame 410 to rotate, and the locking portion 2303 of the positioning block 230 enters into the slide groove 4201. The locking cylinder 430 drives the locking hook 450 to move upward, and the locking hook 450 abuts against the locking portion 2303 of the positioning block 230 to lock the tank mouth flange 200 and the docking flange 1.

[0133] The hydrogen gas of the hydrogen explosion furnace enters the material tank 300 through the second interface flange 35, the second gas channel 33, the first gas channel 12 and the gas inlet 11 in sequence, and performs hydrogen explosion treatment on the NdFeB alloy sheets in the hydrogen explosion furnace.

[0134] After the hydrogen crushing of NdFeB is completed, the air pump is started to deliver gas to the purge air pipe 71. The first driver 6 drives the purge air pipe 71 to reciprocate along the first direction. The gas blown out of the purge air pipe 71 purges the residual powder on the inner wall of the air inlet 11 and blows the residual powder into the tank body 310.

[0135] After the residual powder is blown back, the butterfly valve 320 is closed, the locking cylinder 430 drives the locking hook 450 to move downward, unlocking the tank mouth flange 200 and the docking flange 1, the rotating cylinder 460 drives the locking frame 410 to rotate in the opposite direction, the positioning block 230 moves out of the slide groove 4201, and the second driver 560 drives the purging device 100 to move away from the material tank 300.

[0136] After the tank mouth flange 200 is connected to the docking flange 1 , the docking flange 1 , the locking mechanism 400 , the first inner sleeve 22 and the second inner sleeve 32 rotate around the axis along with the material tank 300 .

[0137] The present application can use four locking cylinders 430 and two rotating cylinders 460 to complete the locking action. The four locking cylinders 430 are evenly distributed around the axis of the docking flange 1, and the two rotating cylinders 460 are evenly distributed around the axis of the docking flange 1.

[0138] like Fig.25 As shown, the angle between the projection L1 of the axis of the rotating cylinder 460 in the axial direction of the docking flange 1 and the projection L2 of the axis of the locking cylinder 430 closest to the rotating cylinder 460 in the axial direction of the docking flange 1 is 30 to 75 degrees, so as to reduce the eccentric torque generated by the locking mechanism 400 on the rotating shaft during rotation.

[0139] When locking the tank mouth flange 200 and the docking flange 1, the two rotating cylinders 460 first move to the first preset position, so that the locking frame 410 rotates to the first preset angle, and the two relative locking cylinders 430 pre-lock the tank mouth flange 200 and the docking flange 1, and the pre-locking force of each locking cylinder is 10-50N. However, the two rotating cylinders 460 stop after moving to the end position, and the other two locking cylinders 430 start to pre-lock for the second time, and the pre-locking force of each locking cylinder is 10-50N. Then the four locking cylinders 430 are started at the same time to make the locking force reach the final value. Pre-locking the connection between the tank mouth flange 200 and the docking flange 1 can improve the balance of the locking force around the docking flange 1 and improve the uniformity of the torque on the docking flange 1 in the circumferential direction.

[0140] The material conveying equipment of this embodiment can realize automatic docking between the purge device and the tank mouth flange, and blow the residual powder on the docking flange back to the material tank.
