DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0031] Reference Figure 1-Figure 7 As shown, a rapid cooling sintering furnace comprises a furnace body 1, a base 12 is fixed at the bottom end of the furnace body 1, a heating source 11 is installed inside the furnace body 1, a pipe 2 is arranged inside the heating source 11, the heating source 11 is provided with a plurality of heating tubes arranged in a ring shape with equal intervals, the heating tubes surround the outside of the pipe 2, one end of the pipe 2 is arranged inside the furnace body 1, and the pipe 2 is fixedly connected to the inner side wall of the furnace body 1, an opening 21 is opened at the top of the pipe 2, a cooling box 3 is fixed on the side of the top of the base 12 away from the furnace body 1, one end of the pipe 2 away from the furnace body 1 passes through the middle of the cooling box 3, and the outer side of the pipe 2 is fixedly connected to the cooling box 3, the opening 21 is between the furnace body 1 and the cooling box 3, and a material changing structure is arranged above the cooling box 3; the material changing structure comprises a tray 6 arranged inside the pipe 2, and one side of the cooling box 3 is provided A clamping frame 5 is provided, a flip arm 51 is provided above the cooling box 3, the flip arm 51 is rotatably connected to the clamping frame 5 through a connecting frame, and a container 4 is provided inside the tray 6; a flip door panel 31 is hingedly connected to one end of the pipeline 2 close to the cooling box 3, a threaded rod 61 is rotatably connected to one side of the lower part of the pipeline 2, and a sliding rod 62 is rotatably connected to the other side of the lower part of the pipeline 2, a motor 63 is installed at one end of the furnace body 1 away from the pipeline 2, and the end of the rotating shaft of the motor 63 is fixedly connected to one end of the threaded rod 61, and the ends of the threaded rod 61 and the sliding rod 62 away from the motor 63 are both rotatably connected to a connecting block, and the connecting block is fixedly connected to the bottom end of the pipeline 2, a threaded sleeve is fixed to one side of the bottom end of the tray 6, and the threaded sleeve is threadedly connected to the threaded rod 61, and a sliding sleeve is fixed to the other side of the bottom end of the tray 6, and the sliding sleeve is slidably connected to the sliding rod 62;

[0032] When processing some alloy materials or ceramic materials, in order to make them integrated and more compact and stronger inside, they need to be sintered. During the sintering process, the material to be sintered is placed into the container 4. When the container 4 is full of materials, it is placed into the tray 6 from the position of the opening 21, and then the container 4 is pushed into the area where the pipe 2 is placed inside the furnace body 1. When the tray 6 drives the container 4 to move, the motor 63 is started to rotate, and the motor 63 drives the threaded rod 61 to rotate. The rotation of the threaded rod 61 drives the threaded sleeve at the bottom of the tray 6 to move. During the movement, the sliding sleeve on the other side slides on the outside of the sliding rod 62, which can provide guidance and limit for the tray 6, and can automatically drive the container 4 to move to the required position. At the same time, the area where the pipe 2 is inside the furnace body 1 is sealed, and then the heating source 11 is started to heat the pipe 2. During the heating process, inert gas is input into the furnace body 1 from the outside. At this time, the pipe 2 inside the furnace body 1 is heated, and the pipe 2 conducts heat to the inside of the material through the container 4. The gas and smoke generated by sintering are extracted through external equipment. After a period of time The heating during the heating can make the material sintered. When the material in the container 4 is sintered, it needs to be cooled. At this time, the container 4 is moved to the position where the pipe 2 is placed inside the cooling box 3 by the tray 6, and the container 4 is taken out from the inside of the tray 6. The container 4 will dissipate heat to the pipe 2. At this time, water flow is input into the cooling box 3 through an external device. The water flow can take away the heat on the surface of the pipe 2, and the water flow with heat is discharged to the outside, so as to circulate and cool the container 4 and the material inside the pipe 2. During the cooling process, the door panel 31 is flipped to block the end of the pipe 2 close to the cooling box 3 to prevent the heat of the container 4 from affecting the outside. During the cooling process, the container 4 to be sintered is fixed to the inside of the clamping frame 5, and then the clamping frame 5 is flipped by the flip arm 51 to drive the clamping frame 5, so that the clamping frame 5 can drive the container 4 to be sintered into the inside of the opening 21, and the tray 6 will catch the container 4 to be sintered. Then, the container 4 to be sintered is moved into the inside of the furnace body 1, so that other containers 4 can be sintered while cooling, thereby improving the sintering efficiency. After the container 4 in the cooling box 3 is cooled, it can be taken out.

[0033] Reference Figure 1-Figure 7 As shown, a driving gear 52 is arranged below the flip arm 51, a pulling arm 53 is fixed to the bottom end of the driving gear 52, a baffle 531 is arranged below the pulling arm 53, a flip block 532 is fixed to the top end of the baffle 531, the flip block 532 is hinged to the end of the pulling arm 53 away from the driving gear 52, and a limiting plate 533 is fixed to the end of the pulling arm 53 away from the driving gear 52;

[0034] When the tray 6 drives the container 4 to move into the interior of the cooling box 3, the container 4 will pass the position of the baffle 531. When the container 4 contacts the baffle 531, the baffle 531 will be pushed to flip. The baffle 531 flips under the pulling arm 53 through the flipping block 532. When the tray 6 drives the container 4 to be completely placed in the interior of the cooling box 3, the container 4 is separated from the baffle 531. At this time, the baffle 531 loses the external force and resets downward due to gravity. Then the motor 63 rotates in the reverse direction to drive the tray 6 to move in the reverse direction. During the movement, the tray 6 drives the container 4 to contact the baffle 531 again. At this time, the baffle 531 is pushed in the opposite direction. When the baffle 531 drives the flipping block 532 to flip, the limit plate 533 limits the flipping block 532, so that the baffle 531 can remain stationary. At this time, the baffle 531 pushes the container 4 inside the tray 6 in the reverse direction. After being pushed, the container 4 detaches from the interior of the tray 6, so that the container 4 falls into the interior of the cooling box 3. In this way, the container 4 can be automatically unloaded from the interior of the tray 6.

[0035] Reference Figure 7 As shown, the bottom end of the tray 6 is rotatably connected to a plurality of rotating rods 64, and the plurality of rotating rods 64 are arranged at equal intervals inside the tray 6, and a discharge port is arranged on one side of the tray 6 close to the cooling box 3;

[0036] When the baffle 531 pushes the container 4 to disengage from the inside of the tray 6, it will move toward the discharge port of the tray 6. At the same time, the rotating rod 64 at the bottom end of the tray 6 will roll with the movement of the container 4, thereby reducing the friction when the container 4 moves and making it easier to unload the container 4 from the inside of the tray 6.

[0037] Reference Figure 4-Figure 5 As shown, a plurality of rollers 54 are rotatably connected at equal intervals on both sides of the interior of the clamping frame 5, a ratchet 541 is fixed between two adjacent rollers 54, a ratchet plate 542 is provided on one side of the ratchet 541, the ratchet plate 542 is placed inside the clamping frame 5, and a snap-fit ​​structure can be formed between the ratchet plate 542 and the ratchet 541, a second spring 543 is fixed on the side of the ratchet plate 542 away from the ratchet 541, the other end of the second spring 543 is fixedly connected to the inner wall of the clamping frame 5, a connecting rod 544 is fixed to the bottom end of the ratchet plate 542, and the connecting rod 544 is rotatably connected to the interior of the clamping frame 5;

[0038] When it is necessary to load the container 4 into the interior of the clamping frame 5, the top end of the container 4 is aligned with the bottom end of the clamping frame 5, and then the container 4 is pushed into the interior of the clamping frame 5. At this time, the container 4 moves upward from the bottom of the clamping frame 5. During this process, the two sides of the container 4 will drive the rollers 54 to rotate. When the rollers 54 rotate, the ratchet 541 will be driven to rotate. At this time, the rotation direction of the ratchet 541 will drive the ratchet plate 542 to separate from the groove of the ratchet 541. When the container 4 is loaded into the interior of the clamping frame 5, the container 4 is released. At this time, the gravity of the container 4 causes it to move downward, which will drive the roller 54 to rotate in the opposite direction. At this time, the elastic force of the second spring 543 will push the ratchet plate 542 to fit into the groove of the ratchet 541, which can lock the ratchet 541. The ratchet 541 also drives the roller 54 to be in a fixed state. At this time, the container 4 can be fixed in the interior of the clamping frame 5, which can facilitate the fixing of the container 4 in the interior of the clamping frame 5.

[0039] Reference Figure 4-Figure 5 As shown, a transmission rod 545 is provided on one side of the connecting rod 544 and the roller 54, and the transmission rod 545 is rotatably connected to the inside of the clamping frame 5. Rotating gears are fixed at both ends of the connecting rod 544 and the transmission rod 545, and the gears at both ends of the connecting rod 544 and the transmission rod 545 are meshed with each other. A push plate 546 is fixed on the side of the transmission rod 545 away from the connecting rod 544, and a plug hole is provided at the bottom end of the clamping frame 5 near the push plate 546;

[0040] When it is necessary to separate the container 4 from the clamping frame 5, the push plate 546 is pushed upward through the insertion hole to flip it over. The push plate 546 drives the transmission rod 545 to rotate. The transmission rod 545 drives the connecting rod 544 to rotate by rotating the gear. When the connecting rod 544 rotates, it can drive the ratchet plate 542 to flip and separate from the ratchet wheel 541. At this time, the roller 54 resumes rotation, which makes it easy to take the container 4 out of the clamping frame 5.

[0041] Reference Figure 1-Figure 4 As shown, a connecting shaft is fixed between the flip arms 51, the connecting shaft is located at the end of the flip arm 51 away from the clamping frame 5, the flip arm 51 is fixed in the middle of the connecting shaft, the connecting shaft is rotatably connected to the top of the cooling box 3 through two support plates, the top of the cooling box 3 is provided with a through hole, a support rod 521 is fixed inside the through hole, the driving gear 52 is arranged inside the through hole of the cooling box 3, the support rod 521 runs through the inside of the driving gear 52, and the top of the driving gear 52 is meshed and connected with the transmission gear 511;

[0042] When the flip arm 51 is flipped, the pulling arm 53 pulls the driving gear 52 to rotate, and the driving gear 52 drives the transmission gear 511 to rotate, and the transmission gear 511 drives the flip arm 51 to flip. During the flipping process, the clamping frame 5 will always keep the top of the container 4 upward due to gravity. When the flip arm 51 is flipped 180°, the flip arm 51 drives the clamping frame 5 to be placed inside the opening 21. At this time, the tray 6 moves to a position above the opening 21. At this time, the container 4 falls down and the tray 6 can pick it up, and automatic material discharge can be achieved.

[0043] Reference Figure 1-Figure 9 As shown, push rods 65 are fixed on both sides of the top of the tray 6 near the discharge port, top blocks 211 are fixed on both sides of the opening 21, two groups of support blocks 32 are arranged on the top of the cooling box 3, and the support blocks 32 are respectively arranged at two flip positions of the flip arm 51, and a telescopic hole is opened inside the support block 32, a first spring 321 is fixed at the bottom end of the telescopic hole, and a top column 322 is fixed on the top of the first spring 321;

[0044] When the baffle 531 pushes the container 4 inside the tray 6 to unload it, it will continue to move, and then the push rod 65 will contact the baffle 531. Under the pulling force of the tray 6, the push rod 65 will push the baffle 531, and the baffle 531 will pull the pulling arm 53, and the pulling arm 53 will pull the driving gear 52 to rotate, at this time, the flip arm 51 can be driven to flip and drive the clamping frame 5 to discharge the material. When the clamping frame 5 is placed inside the opening 21, the top block 211 will extend into the jack of the clamping frame 5 and push the push plate 546. After the container 4 inside the clamping frame 5 falls off, the tray 6 can pick it up, and automatic discharge can be achieved. When the flip arm 51 flips to both sides, the support block 32 will support the flip arm 51. At the same time, the first spring 321 drives the top column 322 to extend and retract inside the support block 32, so as to achieve buffering of the flip arm 51.

[0045] Reference Figure 3-Figure 4 As shown, torsion springs 522 are fixed on both sides of the driving gear 52, and the other side of the torsion spring 522 is fixedly connected to the inner wall of the through hole, and the torsion spring 522 is sleeved on the outside of the support rod 521;

[0046] After the tray 6 receives the container 4, the push rod 65 will separate from the baffle 531. At this time, the driving gear 52 will rotate in the opposite direction under the action of the torsion spring 522. At this time, the flip arm 51 can be driven to flip back and reset, and then other containers 4 can continue to be loaded.

[0047] Reference Figure 1-Figure 10As shown, an insulation frame 22 is arranged outside the pipe 2 between the furnace body 1 and the opening 21, an insulation board 221 is hinged inside the insulation frame 22, and a slot is provided on the insulation board 221 at the position of the threaded rod 61 and the slide rod 62, a sealing plate 222 is arranged below the slot, an articulation block 223 is hinged below the sealing plate 222, the bottom end of the articulation block 223 is fixedly connected to the inner side of the insulation frame 22, the sealing plate 222 and the articulation block 223 are hinged through a rotating shaft, a coil spring is fixed outside the rotating shaft, the outside of the coil spring is fixedly connected to the articulation block 223, and both ends of the rotating shaft are fixedly connected to the sealing plate 222;

[0048] When in use, the heat insulation frame 22 can insulate the pipeline 2 to prevent the heat of the furnace body 1 from being transferred to the position of the cooling box 3. At the same time, the heat insulation board 221 shields the interior of the furnace body 1. The side of the heat insulation board 221 is provided with a sealing strip to seal the furnace body 1. When the tray 6 passes through the heat insulation board 221, it will push it to flip over. After the tray 6 passes, the heat insulation board 221 will flip and reset due to gravity. At the same time, the sealing plate 222 will also flip over. After the tray 6 passes, the sealing plate 222 will be automatically reset by the coil spring, thereby achieving sealing of the interior of the furnace body 1 to prevent external gas from entering the furnace body 1 and affecting the sintering effect.

[0049] Working principle: When sintering the material, fill the container 4 with the material, then put the container 4 into the tray 6 from the opening 21, the motor 63 drives the threaded rod 61 to rotate, and the rotation of the threaded rod 61 drives the threaded sleeve at the bottom of the tray 6 to move, at this time the tray 6 pushes the container 4 into the area where the pipe 2 is placed inside the furnace body 1, and at the same time seals the area where the pipe 2 is inside the furnace body 1, then starts the heating source 11 to heat the pipe 2, and during the heating process, inert gas is input into the furnace body 1 from the outside, at this time the pipe 2 inside the furnace body 1 is heated, and the pipe 2 conducts the heat to the material through the container 4, and the gas and smoke generated by sintering are extracted through external equipment;

[0050] During the sintering process, other containers 4 to be sintered are loaded into the interior of the clamping frame 5, the top end of the container 4 is aligned with the bottom end of the clamping frame 5, and then the container 4 is pushed into the interior of the clamping frame 5. At this time, the container 4 moves upward from the bottom of the clamping frame 5. During this process, both sides of the container 4 will drive the rollers 54 to rotate. The rollers 54 will also drive the ratchet 541 to rotate. At this time, the rotation direction of the ratchet 541 will drive the ratchet plate 542 to separate from the groove of the ratchet 541. When the container 4 is loaded into the interior of the clamping frame 5, the container 4 is released. At this time, the gravity of the container 4 causes it to move downward, which will drive the roller 54 to rotate in the opposite direction. At this time, the elastic force of the second spring 543 will push the ratchet plate 542 to fit into the groove of the ratchet 541, so that the ratchet 541 can be stuck. The ratchet 541 also drives the roller 54 to be in a fixed state. At this time, the container 4 can be fixed in the interior of the clamping frame 5.

[0051] After a period of heating, the material can be sintered. When the material in the container 4 is sintered, it needs to be cooled. At this time, the motor 63 is started to rotate in the opposite direction to drive the tray 6 to move the container 4 from the pipe 2 inside the furnace body 1 to the position inside the cooling box 3. When the tray 6 drives the container 4 to move inside the cooling box 3, the container 4 will pass the position of the baffle 531. When the container 4 contacts the baffle 531, it will push the baffle 531 to flip. The baffle 531 flips under the pull arm 53 through the flip block 532. When the tray 6 drives the container 4 to be completely placed inside the cooling box 3, , the container 4 is separated from the baffle 531, at which time the baffle 531 loses the external force and resets downward due to gravity, and then the motor 63 rotates in the reverse direction to drive the tray 6 to move in the reverse direction. During the movement, the tray 6 drives the container 4 to contact the baffle 531 again. At this time, the baffle 531 is pushed in the opposite direction. When the baffle 531 drives the flip block 532 to flip, the limit plate 533 limits the flip block 532 to keep the baffle 531 stationary. At this time, the baffle 531 pushes the container 4 inside the tray 6 in the reverse direction. After being pushed, the container 4 detaches from the inside of the tray 6, and the container 4 is unloaded into the inside of the cooling box 3;

[0052] The unloaded tray 6 moves toward the position of the opening 21 driven by the motor 63, and then the push rod 65 contacts the baffle 531. Under the pulling force of the tray 6, the push rod 65 pushes the baffle 531, and the baffle 531 pulls the pulling arm 53, and the pulling arm 53 pulls the driving gear 52 to rotate, and the driving gear 52 drives the transmission gear 511 to rotate, and the transmission gear 511 drives the flipping arm 51 to flip. During the flipping process, the clamping frame 5 will always keep the top of the container 4 upward due to gravity. When the flipping arm 51 flips 180°, the flipping arm 51 drives the clamping frame 5 to be placed inside the opening 21. During this process, the top block 211 will extend into the jack of the clamping frame 5 and push the push plate. 546, the top block 211 pushes the push plate 546 to flip, the push plate 546 drives the transmission rod 545 to rotate, the transmission rod 545 drives the connecting rod 544 to rotate by rotating the gear, and when the connecting rod 544 rotates, it can drive the ratchet plate 542 to flip and separate from the ratchet 541, at this time, the roller 54 resumes rotation, which can facilitate the container 4 to be taken out from the inside of the clamping frame 5, and the tray 6 can receive the container 4 after it falls off from the clamping frame 5, when the flip arm 51 flips to both sides, the support block 32 will support the flip arm 51, and at the same time, the first spring 321 drives the top column 322 to retract inside the support block 32, so as to achieve buffering of the flip arm 51;

[0053] After the tray 6 receives the container 4, the push rod 65 separates from the baffle 531. At this time, the driving gear 52 rotates in the opposite direction under the action of the torsion spring 522. At this time, the flip arm 51 is driven to flip and reset in the opposite direction. Then, other containers 4 can be loaded. Then, the motor 63 drives the container 4 to be sintered to enter the area of ​​the pipe 2 inside the furnace body 1, and then the material inside the container 4 to be sintered is sintered.

[0054] At the same time, the container 4 will emit heat to the pipe 2. At this time, water flow is input into the cooling box 3 through external equipment. The water flow can take away the heat on the surface of the pipe 2, and the water flow with heat is discharged to the outside. This cycle can quickly cool the container 4 and the material inside the pipe 2. During the cooling process, sintering is carried out inside the furnace body 1 at the same time.

[0055] At the same time, during the cooling process, the staff loads the container 4 to be sintered subsequently into the clamping frame 5, takes out the container 4 in the cooling box 3 after cooling, and then moves the container 4 that has been sintered subsequently into the cooling box 3, and then repeats the feeding, heating, sintering and cooling in the above manner, which can achieve continuous sintering and allow sintering and cooling to be carried out simultaneously, saving the idle time of the furnace body 1 during cooling. Because the furnace body 1 is continuously sintering, the furnace body 1 can consume less heat when taking out the container 4, so there is no need to preheat the furnace body 1, which can further reduce the consumed time and greatly improve the sintering efficiency.

[0056] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
