[0018] The application will be described in further detail below with reference to the drawings, it is necessary to point out here that the following specific embodiments are only used to further illustrate the application, and cannot be understood as limiting the scope of protection of the application, and the skilled in the art can make some non-essential improvements and adjustments to the application according to the above application content.

[0019] As shown in Figure 1 , Figure 2 and Figure 3 , the application provides a reaction device for preparing NiB binary alloy by magnesium hot rapid reduction, comprising: A rotating drum 1 is horizontally arranged, and both ends of the rotating drum 1 are rotatably arranged on support seats 13. A rotating driving assembly is arranged on the driving end of the rotating drum 1, and the rotating driving assembly is used to drive the rotating drum 1 to rotate along the axis of the rotating drum 1. A heating assembly 2 is arranged outside the rotating drum 1, and the heating assembly 2 is used to heat the material in the closed rotating drum 1. As shown in Figure 1 , the heating assembly 2 is an electromagnetic heating assembly, which comprises an electromagnetic induction coil cylinder and a controller 21. The electromagnetic induction coil cylinder is sleeved outside the rotating drum 1 and is attached to the rotating drum 1. The coil of the electromagnetic induction coil cylinder is electrically connected with the controller 21. The controller 21 is used to control the current intensity of the coil in the electromagnetic induction coil cylinder, so as to control the temperature in the rotating drum 1. A material shoveling assembly is arranged in the rotating drum 1. The material shoveling assembly comprises a material shoveling plate 101, a material guiding plate 102 and a material shoveling driving assembly. The output end of the material shoveling driving assembly is drivingly connected with the material shoveling plate 101. The material shoveling driving assembly is used to drive the material shoveling plate 101 to switch between a shoveling terminal position and an initial position. The material shoveling plate 101 is arranged in front of the material guiding plate 102 along the rotating direction of the rotating drum 1. Under the driving of the material shoveling driving assembly, when the material shoveling plate 101 is shifted from the initial position to the shoveling terminal position along the rotating direction of the rotating drum 1, the material shoveling plate 101 shovels away the part of the material accumulated in the rotating drum 1 due to rotation and guides the shoveling material to the rear position of the material in the rotating drum 1 through the material guiding plate 102.

[0020] As shown in Figure 1 and Figure 2The rotating drum 1 is also equipped with a feeding cover 11 and a vent pipe 12. The feeding cover 11 is used to feed various materials to be heated and reacted into the rotating drum 1, such as powdered nickel oxide, boron trioxide and magnesium. Before feeding, they are mixed evenly. The vent pipe 12 is used to introduce inert gas into the rotating drum 1. After opening the feeding cover 11, the various powders are mixed evenly and then fed into the rotating drum 1 through the feeding cover 11. After closing the feeding cover 11, inert gas, such as nitrogen, is supplied into the rotating drum 1 through the vent pipe 12 to vent the air in the rotating drum 1. This prevents the magnesium powder from being oxidized due to oxygen in the air during the subsequent magnesium thermal reduction process, and ensures that the magnesium thermal reduction reaction proceeds fully. Continue reading Figure 1 and Figure 2 The rotation drive assembly includes a first motor 31, a gear 32, a gear ring 33, a roller 35, and a convex ring 34. The output end of the first motor 31 is connected to the gear 32, which meshes with the gear ring 33. The gear ring 33 is fixedly installed outside the rotating drum 1. The convex ring 34 is fixedly installed outside the rotating drum 1. The roller 35 is frictionally abutted against the lower part of the convex ring 34. The roller 35 is mounted on the base 36, and the support seat 13 is also mounted on the base 36. Under the drive of the first motor 31, the rotating drum 1 rotates at a constant speed. by Figure 4 Taking orientation as an example, the rotating drum 1 rotates clockwise at a constant speed. The short dashed line indicates the accumulation of material inside the drum 1 due to its rotation. The thicker accumulation is located at the lower rear of the drum 1. The long dashed arrow indicates the swing direction of the shovel plate 101. At this time, the shovel plate 101 rotates in the same direction as the rotating drum 1, and its rotational speed is greater than that of the drum 1. The shovel plate 101 then removes the excess material at the rear position. Figure 8 As shown, the shovel plate 101 is located at the shovel end position. At this time, the shoveled material is guided to the guide plate 102, and under its own gravity, the material slides down the guide plate 102 and is guided to the rear position of the previous material accumulation position. This achieves the pre-distribution of the accumulated material to the rear, thereby avoiding the continuous accumulation of the material from the front overturning in the lower middle position of the rotating drum 1, reducing the accumulation thickness of the middle material, and the material pre-distributed to the rear comes into contact with the rotating drum 1 first. As the rotating drum 1 rotates, it falls to the highest position of the accumulation, extending the movement path, that is, extending the contact time between the material and the rotating drum 1, so as to ensure the full reaction.

[0021] The guide plate 102 and the shovel plate 101 are made of thermally conductive materials, such as copper-chromium-zirconium alloy, to heat the material when it is being conveyed.

[0022] For example, see [link to relevant documentation]. Figure 4 ,Figure 5 and Figure 6 The shovel plate 101 includes a shovel tooth 101b and a shovel plate 101a, the outer end of the shovel plate 101a is fixedly arranged with the shovel tooth 101b, and the end of the shovel plate 101a away from the shovel tooth 101b is drivingly connected with the output end of the shovel driving assembly, wherein the shovel tooth 101b is internally provided with a movable cavity 101d, and the movable cavity 101d is internally placed with a counterweight 101c.

[0023] In the process that the shovel plate 101a is swung from low to high by shovel material along the dotted arrow direction, the material on the side of the shovel tooth 101b slides along the shovel plate 101a and the guide plate 102 in turn, and the impact of the counterweight 101c in the movable cavity 101d causes the shovel tooth 101b to vibrate rigidly, and then the shovel plate 101a itself also vibrates, thereby helping the powder on the shovel plate 101a to completely slide off and ensuring the effect of discharging.

[0024] Further referring to Figure 7 The shovel driving assembly includes a lifting driving member 111, a second motor 109 and a main shaft 107, one end of the support seat 13 towards the inside of the rotating drum 1 is fixedly provided with an end plate 104, the end plate 104 is slidingly provided with a displacement plate 103, the sliding direction of the displacement plate 103 and the end plate 104 is perpendicular to the axis of the rotating drum 1, one side of the displacement plate 103 away from the rotating drum 1 is fixedly provided with a support 110, the support 110 is fixedly arranged on the driving end of the lifting driving member 111, one end of the shovel plate 101a away from the shovel tooth 101b is fixedly connected with the main shaft 107, both ends of the main shaft 107 respectively penetrate through the corresponding displacement plate 103 and are rotationally connected with the displacement plate 103, the second motor 109 is arranged on the support 110, and the output end of the second motor 109 is drivingly connected with the main shaft 107.

[0025] As shown in Figure 8 At this time, the shovel plate 101 completes a shovel, and then two lifting driving members 111 are started at the same time to drive the support 110 to move upwards, so that the displacement plate 103 and the guide plate 102 and the shovel plate 101 outside the displacement plate 103 are synchronously moved upwards, then the second motor 109 is started to drive the main shaft 107 to swing the shovel plate 101 counterclockwise to the initial position, that is, the position shown in Figure 9 Then the lifting driving member 111 is driven to move the support 110 downwards, so that the shovel tooth 101b is inserted into the material in the super-high position, and under the driving of the second motor 109, the shovel plate 101 rotates clockwise along the dotted arrow direction, performs a shovel operation, and rotates to the shovel terminal position shown in Figure 4 Figure 8 The above operation is repeated, and the next shovel operation can be performed.

[0026] ​The support base 13 has an inner cavity on the side away from the rotating drum 1. The second motor 109 and the lifting drive component 111 are both located in the inner cavity. An inspection door 131 is provided at the outer end of the inner cavity to facilitate the regular inspection of the transmission components in the inner cavity by the staff.

[0027] Continue reading Figure 4 and Figure 5 A first protrusion 105 is fixedly provided at the lower part of one end of the guide plate 102 near the scraper plate 101. A plurality of second protrusions 106 are fixedly provided on the outside of the main shaft 107. The second protrusions 106 abut against the first protrusions 105. An installation block is fixedly provided at the lower end of the guide plate 102. The installation block is rotatably connected to the secondary shaft. The two ends of the secondary shaft are respectively fixed on the shift plate 103. A torsion spring is sleeved at the rotatable connection between the installation block and the secondary shaft.

[0028] Along the material scraper 101 Figure 4 When the dashed arrow rotates clockwise, the second protrusion 106 abuts against the first protrusion 105. Under the action of the torsion spring, the guide plate 102 vibrates intermittently, which helps to shake the material off the guide plate 102 completely.

[0029] And along the direction of rotation of the rotating drum 1, such as Figure 4 As shown in the clockwise direction, a baffle 108 is fixedly provided in front of the shovel plate 101a. The end of the baffle 108 away from the shovel teeth 101b is a spring sheet structure, and the outer end of the spring sheet structure rubs against the guide plate 102. Figure 5 As shown, the spring-loaded structure of the baffle 108 abuts against the guide plate 102. With the continued rotation of the scraper plate 101, as... Figure 8 As shown, at this time, the spring sheet structure is located above the guide plate 102 to realize the transition of material between the shovel plate 101 and the guide plate 102, and the vibration of the guide plate 102 will also be transmitted to the spring sheet structure. With the help of the elastic vibration of the spring sheet structure, the material is further pushed out.

[0030] For example, see [link to relevant documentation]. Figure 3 and Figure 4 Multiple support plates 14 are evenly arranged on the inner wall of the rotating drum 1, with the inclination direction of the support plates 14 consistent with the rotation direction of the rotating drum 1. Adjacent support plates 14 are staggered along the rotation axis of the rotating drum 1. Thus, under the action of the support plates 14, the material is lifted to the highest point inside the rotating drum 1 before sliding down. During the material falling process, the scattered material is fully exposed to the heat radiated by the rotating drum 1, and the spilled material is collected again by the shovel plate 101 and guided to the rear. The process of being lifted back to the highest point by the support plates 14 extends the overall contact time between the material and the rotating drum 1, ensuring that the material is fully heated and guaranteeing the reaction quality.

[0031] It should be noted that the reaction device for preparing NiB binary alloy by magnesium heat rapid reduction, in use, the feeding cover 11 is opened, a plurality of powders are mixed uniformly and then fed into the rotating drum 1 through the feeding cover 11, after the feeding cover 11 is closed, inert gas such as nitrogen is sent into the rotating drum 1 through the air pipe 12, the air in the rotating drum 1 is exhausted, and the air pipe 12 and the feeding cover 11 are closed, so that the rotating drum 1 is in a closed state; The first motor 31 is started, the gear 32 meshes with the gear ring 33, the rotating drum 1 is rotated, at this time, the shovel plate 101 is located at the position shown in the figure, and the two lifting driving members 111 are started to drive the support 110 to move upwards, so that the displacement plate 103 and the guide plate 102 and the shovel plate 101 outside the displacement plate 103 move upwards synchronously, then the second motor 109 is started, the main shaft 107 drives the shovel plate 101 to swing counterclockwise to the initial position, that is, the position shown in the figure. Figure 8 Figure 9 The lifting driving member 111 is driven to move the support 110 downwards, the shovel teeth 101b of the shovel plate 101 shovel into the material in the super-high position, and under the driving of the second motor 109, the shovel plate 101 rotates clockwise along the dotted arrow direction, so that the shovel teeth 101b of the shovel plate 101 shovel away the material in the super-high position and guide the material to a position behind the previous material accumulation position along the guide plate 102, so as to reduce the accumulation thickness of the intermediate material. Figure 4 During the rotation of the shovel plate 101, the second protrusion 106 frictionally abuts against the first protrusion 105, the guide plate 102 is shaken under the action of the torsional spring, and the baffle 108 provided on the shovel plate 101a has a spring piece structure abutting against the guide plate 102, when the guide plate 102 shakes, the spring piece structure also shakes, which is helpful to shake off the material on the shovel plate 101a and the material on the guide plate 102.

[0032] The above-described embodiments only express several embodiments of the present application, the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application.​​
