Description
Technical Field
[0001] This invention relates to the field of sintering furnace technology, and in particular to a vacuum degreasing sintering high-speed cooling furnace. Background Technology
[0002] A vacuum sintering furnace is a furnace that performs protective sintering of heated items in a vacuum environment. There are many heating methods, such as resistance heating, induction heating, and microwave heating. Vacuum sintering furnaces are often used in the processing of semi-metallic and ceramic materials. High-speed cooling furnaces for sintering have the effect of rapidly cooling the objects after sintering, and are therefore widely used because of their rapid cooling effect.
[0003] The inventors discovered that when workers feed or pull ceramic materials into or out of the sintering furnace, they usually place multiple ceramic objects on a flat plate and then use a forklift or other conveying tool to push the plate into the tank for sintering. However, because the flat plate lacks a fixing mechanism, the objects may slide or shake during the pushing process, causing the objects to shift in position and fall and be damaged. Summary of the Invention
[0004] This invention proposes a vacuum degreasing sintering high-speed cooling furnace to solve the problem that the lack of a fixing mechanism on the plate may cause objects to slide or shake during the pushing process, resulting in the objects falling and being damaged.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum degreasing sintering high-speed cooling furnace, comprising a tank body, a base provided at the bottom of the tank body, a controller provided on one side of the tank body, a safety valve provided on one side of the tank body, a cooler provided on one side of the tank body, the cooler being connected to the tank body via a pipe, a burner provided on one side of the tank body, a sealing door provided on one side of the tank body, and a limiting device for fixing objects provided inside the tank body.
[0006] The aforementioned components achieve the following effects: By setting a limiting device, personnel can fix objects on the flat plate and stably place them into the tank, reducing the possibility of objects falling and getting damaged when multiple objects are placed on the flat plate and pushed. At this time, personnel can turn on the burner through the controller, which heats the inside of the tank through combustion, allowing the tank to sinter the objects inside through high temperature. During the sintering process, a safety valve ensures the safety of the pressure inside the tank. After sintering is completed, the controller turns on the cooler, which generates cold air and cold gas that enters the tank through pipes to quickly cool the objects, achieving a high-speed cooling effect.
[0007] Preferably, the limiting device includes a rectangular frame, a transmission device is provided between the base and the rectangular frame, a support block is fixedly connected to one side of the rectangular frame, one side surface of the support block is arc-shaped, the arc-shaped side of the support block is in contact with the inner wall of the tank, a first circular hole is opened on one side of the rectangular frame, a bidirectional screw is provided inside the first circular hole, the surface thread shape of the bidirectional screw is arranged in opposite symmetrical patterns, one end of the bidirectional screw is rotatably connected to the inner wall of the rectangular frame, two first screw hole blocks are symmetrically threaded on the surface of the bidirectional screw, a rectangular rod is fixedly connected to one side of each of the two first screw hole blocks, a plurality of first rectangular blocks are fixedly connected to one side of each of the two rectangular rods, a first clamping plate is fixedly connected to one side of each of the plurality of first rectangular blocks, a plurality of second rectangular blocks are fixedly connected to the inner wall of the rectangular frame on the symmetrical side of the first clamping plate, and a second clamping plate is fixedly connected to the side of each of the plurality of second rectangular blocks near the first clamping plate.
[0008] The effect achieved by the above-mentioned components is as follows: By setting a limiting device, personnel can place multiple objects to be processed inside the rectangular frame and manually rotate the bidirectional screw. The bidirectional screw rotates inside the first circular hole, causing the bidirectional screw to drive two first screw hole blocks to move in opposite directions along the surface of the bidirectional screw. The two first screw hole blocks drive two rectangular rods to move in opposite directions, and the two rectangular rods drive multiple first clamping plates to move in opposite directions through the first rectangular blocks. During the opposite movement, the first clamping plates come into contact with the surface of the objects and push the objects. When the objects move to the position where they are in contact with the inner side of the second clamping plate, with the support of the second rectangular blocks, the first clamping plates push the objects and clamp and fix them in place. This prevents shaking when multiple objects are placed inside the rectangular frame and pushed into the tank, reducing the possibility of objects accidentally falling and being damaged due to shaking and sliding during the pushing process. This improves the stability of the objects during the pushing process into the tank.
[0009] Preferably, a bearing is fixedly connected to one end of the bidirectional screw near the inner wall of the rectangular frame, and the outer ring of the bearing is fixedly connected to the inner wall of the rectangular frame.
[0010] The effect achieved by the above components is that by setting bearings, the wear between the bidirectional screw and the inner wall of the rectangular frame can be reduced, the rotation effect between the bidirectional screw and the rectangular frame can be improved, and the rotation life between the bidirectional screw and the rectangular frame can be increased.
[0011] Preferably, an operating block is fixedly connected to the end of the bidirectional screw away from the bearing, and the surface of the operating block has multiple insertion holes arranged at equal intervals.
[0012] The effect achieved by the above-mentioned components is as follows: by setting the operating block, the contact area between the hand and the bidirectional screw can be increased, allowing the operator to insert their hand into the through hole and manually rotate the operating block under the action of multiple insertion holes. This causes the operating block to drive the bidirectional screw to rotate, making it easier for the operator to manually rotate the bidirectional screw and improving the convenience of manually rotating the bidirectional screw.
[0013] Preferably, a stop block is fixedly connected to the middle surface of the bidirectional screw, and the surface of the stop block is larger than the inner wall of the first screw hole block.
[0014] The effect achieved by the above-mentioned components is as follows: by setting the stop block, the stop block can intercept the two first screw hole blocks during the movement, so that there is a certain gap between the two first screw hole blocks. This reduces the situation where the two first screw hole blocks collide for a long time or many times when they move in opposite directions on the surface of the bidirectional screw, causing severe wear on the surface of the first screw hole blocks, and improves the service life of the two first screw hole blocks.
[0015] Preferably, a limiting block is fixedly connected to one side of each of the two first screw hole blocks, and a limiting groove is formed on the inner wall of the rectangular frame. The surfaces of the two limiting blocks are slidably connected to the inner wall of the limiting groove, respectively.
[0016] The effect achieved by the above components is as follows: by setting the limiting blocks and limiting grooves, the two limiting blocks can slide inside the limiting grooves. At the same time, the two limiting blocks, together with the limiting grooves, can assist in limiting the two first screw hole blocks, reducing the shaking of the two first screw hole blocks when they move towards each other inside the rectangular frame, and improving the stability of the two first screw hole blocks during movement and use.
[0017] Preferably, the transmission device includes a slide rail, which is fixedly connected to the base. A second circular hole is provided on one side of the slide rail. A first motor is fixedly connected to the side of the slide rail near the second circular hole. A threaded rod is fixedly connected to the output end of the first motor. The threaded rod is disposed inside the second circular hole. The end of the threaded rod away from the first motor is rotatably connected to the base. A second threaded hole block is threadedly connected to the surface of the threaded rod. The surface of the second threaded hole block is slidably connected to the inner wall of the slide rail. An L-shaped rod is fixedly connected to one side of the second threaded hole block. A connecting rod is fixedly connected to one side of the L-shaped rod. A drag rod is fixedly connected to one side of the connecting rod. A circular groove is provided on one side of the rectangular frame. The surface of the drag rod is slidably connected to the inner wall of the circular groove. An L-shaped plate is fixedly connected to one side of the connecting rod. An electric telescopic rod is fixedly connected to one side of the L-shaped plate.
[0018] The effect achieved by the above components is as follows: By setting up a transmission device, after the object is sintered inside the tank, the first motor is turned on, causing the first motor to drive the threaded rod to rotate inside the slide rail. The threaded rod drives the second threaded hole block to move left and right inside the slide rail. The second threaded hole block drives the L-shaped rod to move left and right, causing the L-shaped rod to move left and right, causing the connecting rod to move left and right, causing the connecting rod to move the drag rod left and right. When the drag rod moves to the position of inserting into the circular groove, the electric telescopic rod is opened under the support of the L-shaped plate, causing the electric telescopic rod to extend and retract upward. The electric telescopic rod pushes the rectangular frame upward, and the electric telescopic rod, together with the drag rod, compresses and fixes the rectangular frame. At this time, the first motor drives the L-shaped rod to move left and right through the threaded rod and the second threaded hole block. The L-shaped rod, together with the drag rod, the L-shaped plate, and the electric telescopic rod, drives the rectangular frame to move left and right. When the rectangular frame moves to the point where it is completely detached from the tank, the transmission device quickly removes the rectangular frame, reducing the inconvenience of personnel removing objects placed inside the rectangular frame. At the same time, it saves resources that would otherwise be wasted by using forklifts or large transmission mechanisms, and improves the convenience of removing objects.
[0019] Preferably, a stabilizing rod is fixedly connected to one side of the L-shaped plate, and the stabilizing rod is fixed at the right angle of the L-shaped plate.
[0020] The effect achieved by the above components is as follows: by setting the stabilizing rod, the stabilizing rod can be located at the right angle of the L-shaped plate to reinforce the L-shaped plate, improve the support strength of the L-shaped plate, reduce the swaying or breakage of the L-shaped plate when supporting the electric telescopic rod, and improve the support stability of the L-shaped plate.
[0021] Preferably, a cooling device is provided on one side of the L-shaped rod. The cooling device includes a support rod, which is fixedly connected to the L-shaped rod. A second motor is fixedly connected to one side of the support rod. A rotating shaft is fixedly connected to the output end of the second motor. A fan blade is fixedly connected to one side of the rotating shaft.
[0022] The effect achieved by the above components is as follows: by setting up a cooling device, the second motor is turned on when the object is taken out through the rectangular frame, so that the second motor drives the rotating shaft to rotate, and the rotating shaft drives the fan blades to rotate. The fan blades generate wind through high-speed rotation, so that the cold air blows on the surface of the object to assist in cooling the object. This reduces the possibility of the object still having residual heat after the first cooling of the cooler, which could cause accidental burns to the hands of personnel when taking the object out of the rectangular frame. It also improves the cooling efficiency of the sintered object.
[0023] Preferably, a protective cover is fixedly connected to the side of the second motor near the output end, and the surface of the protective cover has multiple through holes.
[0024] The effects achieved by the above components are as follows: by setting up a protective cover, the protective cover can cover and wrap around the fan blades, so that the protective cover can intercept external objects and reduce the possibility of damage to the fan blades caused by accidental collisions with external objects during use. At the same time, the multiple through holes can allow air to flow inside the protective cover, reducing the obstruction of the protective cover from the fan blades generating wind.
[0025] In summary, the beneficial effects of the present invention are as follows:
[0026] By setting a limiting device, multiple objects placed inside the rectangular frame can be pushed into the tank without shaking. This reduces the possibility of objects shifting due to shaking and sliding, which could lead to accidental drops and damage. It also improves the stability of pushing objects into the tank.
[0027] By incorporating a transmission mechanism, the rectangular frame can be quickly removed from the tank, reducing the inconvenience caused by placing large objects inside the frame. This also saves resources that would otherwise be wasted using forklifts or large transmission mechanisms, and improves the ease of removing objects.
[0028] By setting up a cooling device, cold air can be blown onto the surface of the removed object to assist in cooling it. This reduces the possibility of the object still having residual heat after the initial cooling of the cooler, which could cause accidental burns to the hands of personnel when removing the object from the rectangular frame. This also improves the cooling efficiency of the sintered object. Attached Figure Description

Detailed Implementation
[0041] Reference Figure 1-7 As shown, this embodiment discloses a vacuum degreasing sintering high-speed cooling furnace, including a tank body 1, a base 2 at the bottom of the tank body 1, a controller 3 on one side of the tank body 1, a safety valve 4 on one side of the tank body 1, a cooler 5 on one side of the tank body 1, the cooler 5 being connected to the tank body 1 via a pipe, a burner 10 on one side of the tank body 1, a sealing door 6 on one side of the tank body 1, and a limiting device 7 for fixing objects inside the tank body 1. By setting the limiting device 7, personnel can fix objects onto a flat plate using the limiting device 7. The items are then stably placed inside the tank 1, reducing the risk of items falling and getting damaged when multiple items are placed on a flat surface and pushed. At this point, the operator turns on the burner 10 via the controller 3, which heats the inside of the tank 1 by burning H2. This allows the tank 1 to sinter the items inside at high temperatures. During the sintering process, the safety valve 4 ensures the safety of the pressure inside the tank. After sintering is complete, the controller 3 turns on the cooler 5, which generates cold air and cold air that enters the tank 1 through pipes to quickly cool the items, achieving a high-speed cooling effect.
[0042] Reference Figure 2-7As shown, this embodiment discloses a limiting device 7 including a rectangular frame 71. A transmission device 8 is provided between the base 2 and the rectangular frame 71. A support block 72 is fixedly connected to one side of the rectangular frame 71. One side surface of the support block 72 is arc-shaped, and the arc-shaped side of the support block 72 is in contact with the inner wall of the tank 1. A first circular hole 715 is opened on one side of the rectangular frame 71. A bidirectional screw 73 is provided inside the first circular hole 715. The surface thread shape of the bidirectional screw 73 is arranged in opposite symmetrical patterns. One end of the bidirectional screw 73 is rotatably connected to the inner wall of the rectangular frame 71. The surface of the bidirectional screw 73 is symmetrically threaded with two first screw hole blocks 74. A rectangular rod 75 is fixedly connected to one side of each of the two first screw hole blocks 74. Multiple first rectangular blocks 76 are fixedly connected to one side of each of the two rectangular rods 75. A first clamping plate 77 is fixedly connected to one side of each of the multiple first rectangular blocks 76. Multiple second rectangular blocks 79 are fixedly connected to the inner wall of the rectangular frame 71 on the symmetrical side of the first clamping plate 77. A second clamping plate 710 is fixedly connected to the side of each of the multiple second rectangular blocks 79 closest to the first clamping plate 77. A limiting device is then set... Position 7 allows personnel to place multiple objects to be processed inside the rectangular frame 71 and manually rotate the bidirectional screw 73. The bidirectional screw 73 rotates within the first circular hole 715, causing the two first screw hole blocks 74 to move oppositely along the surface of the bidirectional screw 73. The two first screw hole blocks 74 then drive two rectangular rods 75 to move oppositely, which in turn drive multiple first clamping plates 77 to move oppositely via the first rectangular block 76. During this opposite movement, the first clamping plates 77 come into contact with and push against the surface of the objects. When the object moves to a position that fits against the inner side of the second clamping plate 710, the first clamping plate 77 pushes the object to cooperate with the second clamping plate 710 to clamp and fix the object. This prevents shaking when multiple objects are placed inside the rectangular frame 71 and pushed into the tank 1. It also reduces the possibility of objects falling out of position and being damaged due to shaking and sliding during the pushing process, thus improving the stability of the objects during the pushing process into the tank 1.
[0043] Reference Figure 2-7As shown, this embodiment discloses a bearing 712 fixedly connected to one end of the bidirectional screw 73 near the inner wall of the rectangular frame 71. The outer ring of the bearing 712 is fixedly connected to the inner wall of the rectangular frame 71. By setting the bearing 712, the bearing 712 can reduce the wear between the bidirectional screw 73 and the inner wall of the rectangular frame 71, thereby improving the rotational effect between the bidirectional screw 73 and the rectangular frame 71, and increasing the rotational life between the bidirectional screw 73 and the rectangular frame 71. The end of the bidirectional screw 73 away from the bearing 712 is fixedly connected to... The operating block 713 has multiple insertion holes on its surface, which are arranged at equal intervals. By setting the operating block 713, the contact area between the hand and the bidirectional screw 73 can be increased. This allows the operator to insert their hand into the through hole 96 and manually rotate the operating block 713, which in turn drives the bidirectional screw 73 to rotate. This improves the convenience of manually rotating the bidirectional screw 73.
[0044] Reference Figure 2-7 As shown, this embodiment discloses a stop 714 fixedly connected to the middle surface of the bidirectional screw 73. The surface of the stop 714 is larger than the inner wall of the first screw hole block 74. By setting the stop 714, the stop 714 can intercept the two first screw hole blocks 74 during movement, so that there is a certain gap between the two first screw hole blocks 74. This reduces the situation where the two first screw hole blocks 74 collide for a long time or many times when they move towards each other on the surface of the bidirectional screw 73, causing severe wear on the surface of the first screw hole blocks 74, thus improving the service life of the two first screw hole blocks 74. Each side is fixedly connected with a limiting block 716, and a limiting groove 717 is opened on the inner wall of the rectangular frame 71. The surfaces of the two limiting blocks 716 are slidably connected to the inner wall of the limiting groove 717. By setting the limiting blocks 716 and the limiting groove 717, the two limiting blocks 716 can slide inside the limiting groove 717. At the same time, the two limiting blocks 716, together with the limiting groove 717, can provide auxiliary limiting for the two first screw hole blocks 74, reduce the shaking of the two first screw hole blocks 74 when they move towards each other inside the rectangular frame 71, and improve the stability of the two first screw hole blocks 74 during movement and use.
[0045] Reference Figure 5 and Figure 8 as well as Figure 9As shown, this embodiment discloses a transmission device 8 including a slide rail 81, which is fixedly connected to a base 2. A second circular hole 82 is provided on one side of the slide rail 81. A first motor 83 is fixedly connected to the side of the slide rail 81 near the second circular hole 82. A threaded rod 84 is fixedly connected to the output end of the first motor 83. The threaded rod 84 is disposed inside the second circular hole 82. The end of the threaded rod 84 away from the first motor 83 is rotatably connected to the base 2. A second threaded hole block 85 is threadedly connected to the surface of the threaded rod 84. The surface of the second threaded hole block 85 is slidably connected to the inner wall of the slide rail 81. An L-shaped rod 86 is fixedly connected to one side of block 85, a connecting rod 87 is fixedly connected to one side of the L-shaped rod 86, and a drag rod 88 is fixedly connected to one side of the connecting rod 87. A circular groove 812 is provided on one side of the rectangular frame 71. The surface of the drag rod 88 is slidably connected to the inner wall of the circular groove 812. An L-shaped plate 89 is fixedly connected to one side of the connecting rod 87, and an electric telescopic rod 810 is fixedly connected to one side of the L-shaped plate 89. By setting a transmission device 8, after the object is sintered inside the tank 1, the first motor 83 is turned on, causing the first motor 83 to drive the threaded rod 84 to rotate inside the slide rail 81, so that the threaded rod... The threaded rod 84 drives the second screw hole block 85 to move left and right inside the slide rail 81, causing the second screw hole block 85 to drive the L-shaped rod 86 to move left and right, causing the L-shaped rod 86 to drive the connecting rod 87 to move left and right, causing the connecting rod 87 to drive the drag rod 88 to move left and right. When the drag rod 88 moves to the position inside the insertion groove 812, the electric telescopic rod 810 is opened under the support of the L-shaped plate 89, causing the electric telescopic rod 810 to extend and retract upwards. This causes the electric telescopic rod 810 to push the rectangular frame 71 upwards, allowing the electric telescopic rod 810 to cooperate with the drag rod 88 to... The rectangular frame 71 is pressed and fixed. At this time, the first motor 83 drives the L-shaped rod 86 to move left and right through the threaded rod 84 and the second screw hole block 85. The L-shaped rod 86, together with the drag bar 88, the L-shaped plate 89 and the electric telescopic rod 810, drives the rectangular frame 71 to move left and right. When the rectangular frame 71 is completely removed from the tank 1, the transmission device 8 quickly removes the rectangular frame 71. This reduces the inconvenience caused by placing large objects inside the rectangular frame 71, while saving resources wasted by using forklifts or large transmission mechanisms and improving the convenience of removing objects.
[0046] Reference Figure 5 and Figure 8 as well as Figure 9 As shown, this embodiment discloses that a stabilizing rod 811 is fixedly connected to one side of the L-shaped plate 89. The stabilizing rod 811 is fixed at the right angle of the L-shaped plate 89. By setting the stabilizing rod 811, the stabilizing rod 811 can be located at the right angle of the L-shaped plate 89 to reinforce the L-shaped plate 89, improve the support strength of the L-shaped plate 89, reduce the swaying or breakage of the L-shaped plate 89 when supporting the electric telescopic rod 810, and improve the support stability of the L-shaped plate 89.
[0047] Reference Figure 8 and Figure 10 As shown, this embodiment discloses a cooling device 9 provided on one side of the L-shaped rod 86. The cooling device 9 includes a support rod 91, which is fixedly connected to the L-shaped rod 86. A second motor 92 is fixedly connected to one side of the support rod 91, and a rotating shaft 93 is fixedly connected to the output end of the second motor 92. A fan blade 94 is fixedly connected to one side of the rotating shaft 93. By providing the cooling device 9, when the object is taken out through the rectangular frame 71, the second motor 92 is turned on, causing the second motor 92 to drive the rotating shaft 93 to rotate. The rotating shaft 93 then drives the fan blade 94 to rotate, and the fan blade 94 generates wind through high-speed rotation. This allows cold air to blow onto the surface of the taken-out object to assist in cooling the object, reducing the initial cooling time of the object in the cooler 5. The residual heat prevents accidental burns to hands when removing objects from inside the rectangular frame 71, thus improving the cooling efficiency of sintered objects. A protective cover 95 is fixedly connected to the side of the second motor 92 near the output end. The surface of the protective cover 95 has multiple through holes 96. By setting the protective cover 95, it can cover and wrap around the fan blade 94, allowing it to intercept external objects and reduce the possibility of damage to the fan blade 94 due to accidental collisions during use. At the same time, the multiple through holes 96 allow air to flow inside the protective cover 95, reducing the obstruction of the fan blade 94 from generating wind.
[0048] The working principle is as follows: First, the personnel can fix the object inside the rectangular frame 71 through the limiting device 7 and place it stably inside the tank 1. At this time, the personnel close the sealing door 6 to achieve a sealed effect inside the tank 1. Then, the personnel turn on the burner 10 through the controller 3, so that the burner 10 heats the inside of the tank 1 by burning H2, so that the tank 1 sinters the object inside through high temperature. During the sintering process, the safety valve 4 ensures the safety of the pressure inside the tank. After the sintering is completed, the controller 3 turns on the cooler 5, so that the cooler 5 generates cold air and cold gas, which enters the inside of the tank 1 through the pipe to quickly cool the object and achieve a high-speed cooling effect.
[0049] First, the operator can place multiple workpieces to be processed inside the rectangular frame 71 and manually rotate the operating block 713. Under the rotation of the bearing 712, the operating block 713 drives the bidirectional screw 73 to rotate inside the rectangular frame 71. This causes the bidirectional screw 73 to rotate inside the first circular hole 715, which in turn drives two first screw hole blocks 74 to move opposite to each other along the surface of the bidirectional screw 73. The two first screw hole blocks 74 then drive two limiting blocks 716 to move opposite to each other inside the limiting groove 717. Finally, the two first screw hole blocks 74 drive two rectangular rods 75 to move opposite to each other, allowing the two rectangular rods 75 to pass through the first rectangular blocks 76. The first clamping plates 77 are moved in opposite directions, causing them to come into contact with the surface of the object and push it. When the object moves to a position where it is in contact with the inner side of the second clamping plate 710, the second rectangular block 79 supports the second clamping plate 710, causing the first clamping plates 77 to push the object and cooperate with the second clamping plate 710 to clamp and fix the object. After the object is sintered inside the tank 1, the sealing door 6 and the first motor 83 are opened, causing the first motor 83 to drive the threaded rod 84 to rotate inside the slide rail 81. The threaded rod 84 drives the second threaded hole block 85 to move left and right inside the slide rail 81, causing the first... The screw block 85 drives the L-shaped rod 86 to move left and right, which in turn drives the connecting rod 87 to move left and right, which in turn drives the drag rod 88 to move left and right. When the drag rod 88 moves to the position inside the insertion groove 812, the electric telescopic rod 810 opens under the support of the L-shaped plate 89, causing the electric telescopic rod 810 to extend and retract upwards. This causes the electric telescopic rod 810 to push the rectangular frame 71 upwards, so that the electric telescopic rod 810, together with the drag rod 88, presses and fixes the rectangular frame 71. At this time, the first motor 83 drives the L-shaped rod 86 to move left and right through the threaded rod 84 and the second screw block 85. The movement to the right causes the L-shaped rod 86, in conjunction with the drag bar 88, L-shaped plate 89, and electric telescopic rod 810, to move the rectangular frame 71 left and right. When the rectangular frame 71 is completely removed from the tank 1, the transmission device 8 quickly removes the rectangular frame 71. At the same time, the rectangular frame 71 can be quickly put back into the tank 1 through the above operation. When the rectangular frame 71 is completely removed from the tank 1, the second motor 92 is turned on, causing the second motor 92 to drive the rotating shaft 93 to rotate, which in turn drives the fan blade 94 to rotate. The fan blade 94 generates wind through high-speed rotation, causing cold air to blow on the surface of the removed object to complete the auxiliary cooling of the object.
