Description

Technical Field

[0001] The present invention belongs to the field of conveying technology, specifically relates to material handling, and in particular to a box-type graphitization furnace high-temperature powder sintering conveying device and a working method. Background Art

[0002] During the sintering process, the powder is first injected into the sintering tank and then sintered. The high sintering temperature will cause the shape of the sintering tank to change, but the speed at which the powder is injected into the sintering tank remains unchanged. As a result, when the sintering tank is deformed, especially when part of the inner wall of the sintering tank bulges, causing the volume of the sintering tank to become smaller, the powder injected into the sintering tank will overflow the sintering tank.

[0003] Therefore, due to the technical problem that the deformation of the sintering tank causes the powder to overflow the sintering tank and affect the subsequent powder sintering, it is necessary to design a box-type graphitization furnace high-temperature powder sintering conveying device and working method.

[0064] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0065] Since dust is generated during the powder injection process and the dust interferes with visual inspection, it is impossible to use visual inspection to adjust the injection speed when injecting powder material into the sintering tank 31 .

[0066] like Figure 1As shown in at least one disclosed embodiment, a high-temperature powder sintering conveying device for a box-type graphitization furnace is provided, which comprises a feeding mechanism 1, a discharging mechanism 2 and a bearing mechanism 3; the discharging mechanism 2 is arranged at the bottom of the feeding mechanism 1, and the discharging mechanism 2 is located above the bearing mechanism 3; the bearing mechanism 3 is provided with a plurality of sintering grooves 31; the discharging mechanism 2 is adapted to inject the material in the feeding mechanism 1 into the sintering grooves 31, and the discharging port of the discharging mechanism 2 extends into the material in the sintering grooves 31 when the material is injected, and the discharging mechanism 2 is adapted to adjust the discharging speed according to the shape of the inner wall of the sintering grooves 31, thereby reducing the injection speed of the powder when the internal volume of the sintering grooves 31 is reduced, and avoiding overflow of the powder from the sintering grooves 31 under the same injection time.

[0067] As shown in Figure 2 As shown in Figure 3 As shown in Figure 4 As shown in an optional embodiment, the discharging mechanism 2 comprises a discharging pipe 21, a connecting piece 22 and an injection pipe 23; the discharging pipe 21 is vertically arranged on the top surface of the connecting piece 22, and the discharging pipe 21 is in communication with the feeding mechanism 1; the injection pipe 23 is vertically arranged on the bottom surface of the connecting piece 22; the first communication hole 221 is arranged in the thickness direction of the connecting piece 22 to communicate the discharging pipe 21 and the injection pipe 23 through the first communication hole 221.

[0068] In this embodiment, the second communication hole 222 is arranged in the length direction of the connecting piece 22, and the second communication hole 222 is in communication with the first communication hole 221.

[0069] In this embodiment, a pair of moving plates 24 are slidably arranged in the second communication hole 222, one moving plate 24 extends from one end of the second communication hole 222, and the other moving plate 24 extends from the other end of the second communication hole 222; the ends of the two moving plates 24 close to each other extend into the first communication hole 221.

[0070] In this embodiment, the moving plates 24 correspond to the two longer side walls of the sintering grooves 31, and the two longer side walls are more likely to deform.

[0071] In this embodiment, the inner wall of the second communication hole 222 is provided with a sliding groove 223 corresponding to the side wall of the moving plate 24, one end of the sliding groove 223 is closed, and the other end is open, and the opening is located on the side wall of the connecting piece 22;

[0072] In this embodiment, the side wall of the moving plate 24 is provided with a sliding strip 241, and the sliding strip 241 is located in the corresponding sliding groove 223; the sliding strip 241 and the inner wall of the closed end of the sliding groove 223 are connected by a spring, which can facilitate the resetting of the moving plate 24.

[0073] In the initial state, the shape and size formed by the two movable plates 24 and the bottom surface of the connecting member 22 is smaller than the shape and size of the open top surface of the sintering tank 31 , so that the movable plates 24 can be lowered into the sintering tank 31 .

[0074] When the part of the movable plate 24 extending out of the second connecting hole 222 contacts the inner wall of the sintering tank 31, it is squeezed by the inner wall of the sintering tank 31, causing the movable plate 24 to shrink into the second connecting hole 222. At this time, the part of the movable plate 24 extending into the first connecting hole 221 increases, so that the part of the first connecting hole 221 that is blocked increases.

[0075] When the sintering tank 31 is deformed, especially when the inner wall of the sintering tank 31 bulges, the volume of the sintering tank 31 will decrease. At this time, if the original powder injection speed and injection time are maintained, the powder will overflow from the sintering tank 31 with a reduced volume.

[0076] In the initial state, the movable plate 24 extends out of the second connecting hole 222. When the first cylinder 14 drives the telescopic pipe 15 to descend, the connecting piece 22 descends synchronously, and the movable plate 24 descends into the sintering tank 31. When the movable plate 24 contacts the inner wall of the sintering tank 31, if the inner wall of the sintering tank 31 is convex, the movable plate 24 is squeezed by the inner wall of the sintering tank 31, causing the movable plate 24 to shrink into the second connecting hole 222. At this time, the part of the movable plate 24 extending into the first connecting hole 221 increases, so that the part of the first connecting hole 221 that is blocked increases, and the injection speed of the powder is reduced to prevent the powder from overflowing from the sintering tank 31.

[0077] After the bottom end of the injection pipe 23 drops to a preset height from the bottom surface of the sintering tank 31 (this height is lower than the final height of the powder in the sintering tank 31 under standard conditions of the sintering tank 31), the first cylinder 14 stops working, and powder begins to be injected into the sintering tank 31 at this time. The powder gradually rises after entering the sintering tank 31, and the height of the powder is higher than the bottom end of the injection pipe 23. The bottom end of the injection pipe 23 is immersed in the powder to reduce the generation of dust, and at this time, the movable plate 24 blocks the dust generated during the powder injection process. After the bottom end of the injection pipe 23 is immersed in the powder, the first cylinder 14 drives the telescopic pipe 15 to contract so that the connecting piece 22 moves upward, and keeps the bottom end of the injection pipe 23 immersed in the powder during the upward movement. When it rises to the preset height, the first cylinder 14 The first cylinder 14 stops working again, and the powder continues to be injected. The top surface of the powder gradually rises until it contacts the bottom surface of the movable plate 24. At this time, the air in the powder is reduced by pressing the powder with the bottom surface of the movable plate 24. More air in the powder will affect the sintering effect of the powder. After the powder is injected for a certain period of time, the injection of the powder is stopped. The first cylinder 14 continues to drive the connecting piece 22 to move upward, so that the bottom end of the injection pipe 23 moves out of the powder. At this time, the groove formed by the injection pipe 23 extending into the powder is filled with the surrounding powder to avoid the formation of a cone on the surface of the powder when the powder is injected. In the traditional powder injection method, the bottom end of the injection pipe 23 is higher than the top surface of the powder, which will form a cone on the surface of the powder, resulting in affecting the sintering effect during subsequent powder sintering.

[0078] In an optional embodiment, the injection pipe 23 is rotatably connected to the bottom surface of the connecting piece 22; the top surface of the injection pipe 23 is provided with a ring body 231, and the ring body 231 is provided with a pair of arc-shaped holes 232; the bottom surface of the movable plate 24 is provided with a column 242, and the column 242 is located in the corresponding arc-shaped hole 232.

[0079] The movable plate 24 moves after contacting the inner wall of the sintering tank 31 , driving the column 242 to move in the arc-shaped hole 232 , causing the injection pipe 23 to rotate.

[0080] During the powder injection process, the injection pipe 23 rotates to assist in discharging gas in the powder and reduce the gas in the powder.

[0091] The frame 11 may be connected to a driving mechanism so that the frame 11 may move along the slide rail 41 .
