Description

Technical Field

[0001] The utility model relates to the technical field of atmosphere furnace heat dissipation, in particular to a novel vacuum hydrogen burning atmosphere furnace. Background Art

[0002] Vacuum atmosphere furnace, also known as oxygen-free annealing furnace, vacuum atmosphere sintering furnace, etc., is a method of sintering objects in a furnace chamber with a certain gas. Choosing a suitable atmosphere for sintering different materials is helpful for the sintering process, improving the degree of product densification and obtaining products with good performance. Vacuum atmosphere furnaces commonly use various atmospheres such as vacuum, hydrogen, oxygen, nitrogen and inert gas (such as argon). For example, transparent alumina ceramics can be sintered in a hydrogen atmosphere, transparent ferroelectric ceramics are suitable for sintering in an oxygen atmosphere, and nitride ceramics such as aluminum nitride are suitable for sintering in a nitrogen atmosphere. Sometimes, in order to protect the sintering coordination, it is also necessary to operate in a protective atmosphere. For example, a molybdenum wire furnace is suitable for hydrogen, and a tungsten wire furnace is suitable for working under vacuum conditions. However, after the atmosphere furnace is used, the furnace body needs to be cooled to ensure its service life.

When heat dissipation is needed, the driving component can be started to drive the protective plate 2 to be flipped and folded together through the folding component, so that the front side of the protective shell 1 can be opened while avoiding the protective plate 2 from extending too much to increase the occupied area and avoid the problem of bumping. By using the transmission component and the heat dissipation fan 5, the driving component can be used to dissipate the heat inside after the protective plate 2 is opened, thereby accelerating the air flow speed and improving the heat dissipation effect.

[0021] The folding assembly includes a fixed gear 7, which is rotatably connected to the fixed plate 3 on its corresponding side. A first connecting rod 8 is provided on the lower side of the fixed gear 7.

[0024] like Figures 2 to 7As shown, the drive motor 13 is provided to provide power for the operation of the components, and the lead screw 14, the moving tube 15, the moving block 17, the contact plate 18, the driving groove 19, the driving rod 21, the return spring, the plug block 20 and the slot 16 are provided so that when the contact plate 18 contacts the blocking block 23 or contacts the protective shell 1, the contact plate 18 stops, and the moving tube 15 continues to move under the action of the threaded connection, so that the plug block 20 can be moved out of the slot 16 under the action of the driving groove 19 and the driving rod 21, and the moving block 17 can be stopped. Then, the lead screw 14 can be used to drive the screw 22 to rotate within a certain range through the moving block 17, and the drive motor 13 can be used to drive the protective plate 2 to flip and fold, and after the flipping is completed, the drive motor 13 can continue to rotate to drive other components to operate.

[0028] like Figures 1 to 4 As shown, the heat dissipation frame 28 can be provided to perform basic heat dissipation during normal use, and the atmosphere sintering furnace 29 can be provided to sinter the required production materials.

[0029] When the utility model is in use, when heat dissipation is required, the driving motor 13 is started, and the driving motor 13 drives the moving tube 15 to move to the right through the lead screw 14. At this time, the insert block 20 enters the slot 16, and the moving block 17 moves to the right synchronously. At the same time, the moving block 17 drives the screw 22 to rotate, and the rotation of the screw 22 can drive the fixed gears 7 on the left and right sides to rotate. The fixed gear drives the front protection plate 2 to flip and gradually fold upward through the folding assembly, so that the atmosphere sintering furnace 29 is completely exposed to the air to accelerate heat dissipation. When the contact plate 18 contacts the barrier block 23, the insert block 20 is gradually moved out of the slot 16, and the moving block 17 stops moving;

[0030] At this time, the driving motor 13 drives the cooling fan 5 to rotate and dissipate heat through the lead screw 14 and the transmission assembly. When the heat dissipation efficiency needs to be increased, the rotation speed of the driving motor 13 can be increased to drive the two cooling fans 5 to accelerate the heat dissipation.

[0031] After the heat dissipation is completed, the driving motor 13 is reversed, and the protection plate 2 can be reversed and extended to the position shown in the figure, so that the atmosphere sintering furnace 29 can be protected to prevent it from being damaged by foreign objects;

[0032] When there is no need to open the front protection plate 2 for heat dissipation, the drive plate can be started to continuously reverse, and the two cooling fans 5 can be driven to blow air inwards for heat exchange through the lead screw 14 and the transmission assembly, which can also achieve the heat dissipation effect.

[0033] In the present invention, the driving motor 13 is prior art and will not be described in detail here.

[0034] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
