Description

Technical Field

[0001] The 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 will first be 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.

DETAILED DESCRIPTION

[0024] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0025] Since dust is generated during the powder injection process and the dust interferes with visual detection, it is not possible to use visual detection to adjust the injection speed when injecting powder material into the sintering tank 31 .

[0026] like Figure 1 As shown, in at least one disclosed embodiment, a box-type graphitization furnace high-temperature powder sintering and conveying device is provided, comprising: a feeding mechanism 1, a feeding mechanism 2 and a supporting mechanism 3; the feeding mechanism 2 is arranged at the bottom of the feeding mechanism 1, and the feeding mechanism 2 is located above the supporting mechanism 3; a plurality of sintering grooves 31 are opened on the supporting mechanism 3; the feeding mechanism 2 is suitable for injecting the material in the feeding mechanism 1 into the sintering groove 31, and when injecting the material, the feeding port of the feeding mechanism 2 extends into the material in the sintering groove 31, and the feeding mechanism 2 is suitable for adjusting the feeding speed according to the inner wall shape of the sintering groove 31, thereby achieving the reduction of the powder injection speed when the internal volume of the sintering groove 31 becomes smaller, and avoiding the powder overflowing from the sintering groove 31 under the same injection time.

[0027] like Figure 2 As shown, Figure 3 and Figure 4 As shown, in an optional embodiment, the feeding mechanism 2 includes: a feeding pipe 21, a connecting piece 22 and an injection pipe 23; the feeding pipe 21 is vertically arranged on the top surface of the connecting piece 22, and the feeding pipe 21 is connected with the feeding mechanism 1; the injection pipe 23 is vertically arranged on the bottom surface of the connecting piece 22; a first connecting hole 221 is opened in the thickness direction of the connecting piece 22, so that the feeding pipe 21 and the injection pipe 23 are connected through the first connecting hole 221.

[0028] In this embodiment, a second communicating hole 222 is formed in the length direction of the connecting member 22 , and the second communicating hole 222 is communicated with the first communicating hole 221 .

[0029] In this embodiment, a pair of movable plates 24 are slidably disposed in the second connecting hole 222, one movable plate 24 extends from one end of the second connecting hole 222, and the other movable plate 24 extends from the other end of the second connecting hole 222; the ends of the two movable plates 24 that are close to each other partially extend into the first connecting hole 221.

[0030] In this embodiment, the movable plate 24 corresponds to the two longer side walls of the sintering tank 31 , and the two longer side walls are more likely to deform.

[0031] In this embodiment, a slide groove 223 corresponding to the side wall of the movable plate 24 is provided on the inner wall of the second connecting hole 222, one end of the slide groove 223 is sealed, and the other end is open, and the opening is located on the side wall of the connecting member 22; In this embodiment, a sliding bar 241 is provided on the side wall of the movable plate 24, and the sliding bar 241 is located in the corresponding slide groove 223; a spring is connected between the sliding bar 241 and the inner wall of the sealed end of the slide groove 223, and the spring can facilitate the resetting of the movable plate 24.

[0032] In the initial state, the shape and size formed by the two moving 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 moving plates 24 can be lowered into the sintering tank 31 .

[0033] When the portion 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 portion of the movable plate 24 extending into the first connecting hole 221 increases, thereby increasing the portion of the first connecting hole 221 that is blocked.

[0034] 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 be reduced. At this time, if the original powder injection speed and injection time are maintained, the powder will overflow from the sintering tank 31 with reduced volume.

[0035] 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, so that the movable plate 24 shrinks 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.

[0036] After the bottom end of the injection pipe 23 drops to a preset height from the bottom surface of the sintering tank 31 (the height is less 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 a preset height, the first cylinder 14 stops working. The first cylinder 14 stops working again, and the powder is still injected. The top surface of the powder gradually rises until it contacts the bottom surface of the movable plate 24. At this time, the bottom surface of the movable plate 24 presses the powder to reduce the air in the powder. 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.

[0037] 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 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 hole 232.

[0038] The moving 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 , so that the injection pipe 23 rotates.

[0039] When the powder is injected, the injection pipe 23 rotates to assist the gas in the powder to be discharged, thereby reducing the gas in the powder.

[0041] The powder in the discharge bin can first enter the sub-bin 12 . The sub-bin 12 has more discharge ports at the bottom, so that more sintering tanks 31 can be filled at the same time.

[0042] In an optional embodiment, a first cylinder 14 corresponding to the telescopic pipe 15 is provided on the frame 11; the telescopic end of the first cylinder 14 is connected to the telescopic pipe 15; the first cylinder 14 is suitable for driving the telescopic pipe 15 to extend and retract.

[0043] The first cylinder 14 can drive the telescopic pipe 15 to extend and retract, so that the connecting piece 22 descends into the sintering tank 31 .

[0045] The first motor 163 drives the rotating shaft 161 to rotate so as to drive the fan blades 162 to rotate. The rotating fan blades 162 can prevent the powder in the storage bin 13 from accumulating in the valve 16 , so that the powder can smoothly enter the distribution bin 12 from the storage bin 13 .

[0046] In an optional embodiment, a baffle 18 is provided between the sub-bin 12 and the telescopic pipe 15; the baffle 18 is connected to a second cylinder 17; the second cylinder 17 is provided on the sub-bin 12; the second cylinder 17 is suitable for driving the baffle 18 to move.

[0047] The baffle 18 can be set at the connection position between the distribution bin 12 and the telescopic pipe 15, and the second cylinder 17 drives the baffle 18 to move to open or close the connection position; when the powder injection in a sintering tank 31 is completed, the connection position between the distribution bin 12 and the telescopic pipe 15 can be closed by the baffle 18.

[0048] In an optional embodiment, the feeding mechanism 1 is arranged on the moving mechanism 4; the moving mechanism 4 includes: a pair of slide rails 41; the slide rails 41 are arranged opposite to each other; the supporting mechanism 3 is arranged between the two slide rails 41; the frame 11 is arranged on the slide rails 41, and the frame 11 is suitable for moving along the slide rails 41.

[0049] The frame 11 moves along the slide rail 41 so that the injection pipe 23 passes through the corresponding sintering tank 31 to complete the injection.

[0050] The frame 11 may be connected to a driving mechanism so that the frame 11 may move along the slide rail 41 .

[0051] In an optional implementation, the first cylinder 14, the first motor 163 and the second cylinder 17 are electrically connected to a control module and controlled by the control module.
