Description

Technical Field

[0001] The utility model relates to the technical field of upper hoppers, in particular to an upper hopper protection device for a continuous hydrogen crushing furnace. Background Art

[0002] The hydrogen crushing furnace is a processing equipment used to process NdFeB alloy materials. By utilizing the hydrogen absorption characteristics of rare earth metal compounds, the NdFeB alloy is placed in a hydrogen environment, allowing hydrogen to enter the alloy along the Nd-rich phase thin layer, and causing it to expand and burst along the Nd-rich phase layer, breaking and cracking, thereby turning the thin slices into coarse powder, so that the NdFeB can directly enter the next process after being processed in the hydrogen crushing furnace, which can effectively reduce the probability of material oxidation.

[0003] In the prior art, the upper hopper is a common object used to feed the hydrogen crushing furnace. During the feeding process, the upper hopper needs to be lifted to a high place by a lifting mechanism and then dumped so that the material in the upper hopper enters the hydrogen crushing furnace through a guide plate.

[0004] During the dumping process, the material in the upper hopper will slide down under the action of gravity, and the higher the material, the greater the potential energy it will have. In addition, the material at the bottom will be affected by the friction exerted by the adjacent materials and slow down the discharge speed. When a large amount of material is dumped, it will be disturbed by the material below and cause the trajectory to shift. As a result, the material cannot be discharged into the hydrogen crushing furnace along the predetermined trajectory of the guide plate, affecting the NdFeB feeding and increasing the difficulty of subsequent cleaning. Therefore, in order to prevent the NdFeB from scattering during the dumping process, the loading amount of the upper hopper needs to be reduced. Utility Model Content

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1 - Figure 5 The utility model discloses a hopper protection device for a continuous hydrogen crushing furnace, comprising a hopper body 1, a charging trough 2 for loading NdFeB is provided on the top of the hopper body 1, a guide portion 3 is formed on one side of the top of the hopper body 1, both sides of the guide portion 3 are folded to form an anti-slip portion 4, a baffle plate 5 is provided at the opening of the charging trough 2, an anti-collision pad 6 is fixedly connected to the bottom of the baffle plate 5, a side of the baffle plate 5 away from the guide portion 3 is connected to the hopper body 1 through a resistance mechanism 7, and a gap for the discharge of NdFeB is reserved between the side of the baffle plate 5 close to the guide portion 3 and the guide portion 3.

[0026] In this embodiment, due to the structural limitation of the upper hopper, the material in the upper hopper cannot be filled, which affects the feeding efficiency of the NdFeB, thereby reducing the processing efficiency of the hydrogen crushing furnace. Therefore, a material blocking plate 5 is placed on the top of the hopper body 1, which can be used to block the NdFeB during the material pouring process, prevent the pouring trajectory of the NdFeB from deviating, and allow the upper hopper to be used to load more materials, thereby improving the feeding efficiency of the NdFeB and the processing efficiency of the hydrogen crushing furnace.

[0027] During the lifting process, the upper hopper will vibrate due to the existence of the assembly gap, and the NdFeB material itself has a large weight. Therefore, when the upper hopper spills materials due to the shaking, it will injure nearby operators, resulting in a safety hazard when the upper hopper is full of materials. Therefore, the setting of the baffle plate 5 can also prevent the material from spilling during the lifting process of the upper hopper, increase the loading amount of the upper hopper while protecting the material, to prevent the material from spilling due to the shaking of the upper hopper during the lifting process, thereby effectively improving the safety of the upper hopper.

[0028] Observation and Figure 2 It can be found that the guide portion 3 arranged on the bucket body 1 can be used to increase the pouring distance of the NdFeB, so that the NdFeB can better enter the hydrogen crushing furnace, and the anti-slip portions 4 formed by folded edges are arranged on both sides of the guide portion 3, which can block the NdFeB at the edge of the guide portion 3 to prevent the NdFeB at the edge from being squeezed out of the guide portion 3 when the material is piled up and squeezed, causing the material to spill, thereby further preventing the pouring trajectory of the NdFeB from deviating.

[0029] In a further preferred embodiment of the present invention, Figure 2 and Figure 4 As shown, the resistance mechanism 7 includes a connecting seat 71, a connecting block 72 and a connecting shaft 73. The connecting seat 71 is provided with two and is symmetrically fixedly connected to the outer wall of the bucket body 1. A mounting groove 8 is opened on one side of the connecting seat 71 and a connecting block 72 is placed thereon. A connecting shaft 73 is provided between the two connecting seats 71. Both ends of the connecting shaft 73 are respectively inserted into the two connecting seats 71 and are rotatably connected to the connecting blocks 72. The top of the connecting block 72 is fixedly connected to the baffle plate 5.

[0030] In this embodiment, because the baffle plate 5 needs to block the material in the upper hopper to prevent the material from spilling, when the upper hopper is pouring the material, the material will be restricted by the baffle plate 5, resulting in a smaller cross-sectional area for the material to pass through, affecting the discharge efficiency.

[0031] So observe Figure 4 It can be found that the connecting block 72 and the connecting seat 71 rotate through the connecting shaft 73, and then observe Figure 2It can be seen that the connecting block 72 is connected to the baffle plate 5, and the connecting seat 71 is connected to the bucket body 1, so that the baffle plate 5 can rotate around the axis of the connecting shaft 73, so that the upper hopper will be like Figure 2 As shown in the state, as the dumping amplitude increases, the opening angle between the baffle plate 5 and the bucket body 1 will also increase, thereby increasing the cross-section through which the material passes, which can effectively improve the pouring efficiency of the material.

[0032] In a further preferred embodiment of the present invention, Figure 4 As shown, one side outer wall of the connecting block 72 contacts the inner wall of the placement groove, and a pressing block 9 for pressing the connecting block 72 is provided between the other side of the connecting block 72 and the placement groove.

[0033] In this embodiment, a pressure block 9 is provided to squeeze the connecting block 72, thereby increasing the resistance between the connecting block 72 and the pressure block 9, thereby increasing the friction between the connecting block 72 and the pressure block 9, which can be used to fix the opening angle of the baffle plate 5, and to increase the loading amount in the loading trough 2, which can further improve the loading efficiency of the loading hopper.

[0034] In a further preferred embodiment of the present invention, Figure 4 As shown, the outer wall of the connecting shaft 73 located in the placement groove is processed with an external thread and is threadedly connected to the pressing block 9. The two external threads are symmetrically arranged. One end of the connecting shaft 73 extends out of the connecting seat 71 and is fixedly connected to the knob 10.

[0035] In this embodiment, by providing an external thread at the end of the connecting shaft 73, the rotation of the connecting shaft 73 can be used to control the movement of the pressing block 9, thereby changing the distance between the pressing block 9 and the connecting block 72, which can be used to adjust the friction between the pressing block 9 and the connecting block 72, so that the loading hopper can adjust the use state of the baffle plate 5 according to the use situation, so that the loading hopper has a variety of loading efficiencies.

[0036] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, at least one group of elastic rings 11 is arranged between the pressing block 9 and the connecting block 72, each group of the elastic rings 11 is composed of two elastic rings 11 which are gradually inclined from the inside to the outside to form a funnel shape, and the two elastic rings 11 are symmetrically arranged.

[0037] In this embodiment, because friction will be generated between the pressing block 9 and the connecting block 72 when rotating, the upper hopper will be worn after long-term use and the fixing of the baffle plate 5 will be affected. Figure 4It can be found that an elastic ring 11 is provided between the pressing block 9 and the connecting block 72. The elastic ring 11 is utilized to reduce the contact area, thereby effectively reducing wear and tear, thereby extending the service life of the upper hopper.

[0038] And observe Figure 5 It can be found that the elastic ring 11 gradually tilts from the inside to the outside to form a funnel shape, so that when the two elastic rings 11 are squeezed, the funnel-shaped structure can be used to disperse the pressure, which can effectively improve the pressure-bearing capacity of the elastic ring 11 and increase the service life of the elastic ring 11.

[0039] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the bottom of the baffle plate 5 is symmetrically provided with two protrusion-formed baffles 12, the outer wall of the baffle 12 close to the charging trough 2 is in contact with the inner wall of the charging trough 2, and the edge of the baffle 12 away from the charging trough 2 is processed with a chamfer.

[0040] In this embodiment, when the baffle plate 5 is opened, a gap will be generated between the side of the baffle plate 5 and the bucket body 1, which will cause the excess NdFeB material to fall along the gap, increasing the difficulty of subsequent cleaning. Figure 3 It can be found that a material blocking portion 12 is provided at the bottom of the material blocking plate 5. Figure 2 It can be found that the material blocking portion 12 in contact with the inner wall of the charging chute 2 will block the gap generated on the side when the material blocking plate 5 is opened, which can effectively prevent the material from leaking along the gap, thereby further improving the practicality of the upper hopper.

[0041] By providing an inclined surface on the material blocking portion 12, the edge width of the material blocking portion 12 can be reduced, thereby reducing the accumulation of NdFeB materials and making the discharge of the upper hopper more complete.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
