Description

Technical Field

[0001] The utility model relates to a vacuum sintering furnace, in particular to an improved structure of the vacuum sintering furnace. Background Art

[0002] A vacuum sintering furnace is a furnace for protecting and sintering heated articles in a vacuum environment. It adopts various heating methods. The design of the vacuum sintering furnace aims to provide an environment of high vacuum or protective atmosphere to reduce oxidation reaction, so as to obtain higher quality materials. This equipment is widely used in the sintering processing of cemented carbide, metal powder, ceramic materials, etc.

[0003] For the sintering furnace of the prior art, cooling is required after sintering. Since the cooling process is slow, a long cooling time is needed, which slows down the working efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an improved structure of a vacuum sintering furnace.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: The improved structure of the vacuum sintering furnace includes a furnace body. A sealing door is rotatably arranged at the front end of the furnace body. A sintering rack is arranged inside the furnace body. A plurality of layers of U-shaped support pipes are arranged on the outer wall of the sintering rack. An interface is arranged at the outer end of the support pipe and extends out of the sintering rack. A rotating platform is rotatably arranged on the opening side of the furnace body opposite to the sealing door. A water pipe connected to the interface is arranged on the rotating platform.

[0006] It is further set as: Eccentric rotating blades are arranged inside both sides of one of the water pipes. The rotating shaft of the eccentric rotating blades extends out of the water pipe and an extension shaft is arranged. An internal gear is arranged on the extension shaft. Fans are arranged on both sides of the rotating platform. External gears meshing with the internal gear are arranged on the fans.

[0007] It is further set as: The support pipe is arranged obliquely downward outward.

[0008] It is further set as: A water receiving tank is arranged below the rotating platform.

[0009] In summary, the utility model has the following beneficial effects: Through the improved structure, the cooling efficiency inside the vacuum sintering furnace can be accelerated after sintering, thus accelerating the overall working efficiency. Brief Description of the Drawings

[0013] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0014] The improved structure of the vacuum sintering furnace includes a furnace body 1, a sealing door 2 is rotatably arranged at the front end of the furnace body 1, and a sintering rack 3 is arranged inside the furnace body 1.

[0015] A number of layers of U-shaped support pipes 4 are arranged on the outer walls on both sides of the sintering rack 3, and an interface 5 is arranged at the outer end of the support pipe 4 and extends out of the sintering rack 3.

[0016] A rotating platform 6 is rotatably arranged on the furnace body 1 at the opening position of the sealing door 2 (as shown on the left side of the figure, this side of the vacuum sintering furnace is usually in a vacant state). Multiple layers of water pipes 7 are arranged on the rotating platform 6. After the water pipes 7 are connected to the interfaces 5, water can be supplied to the support pipes 4, thereby realizing the cooling of the inside of the furnace body 1 and the sintering rack 3.

[0017] Among them, the support pipe 4 extends obliquely downward from the inside to the outside. A horizontal section can be arranged at the interface 5 to facilitate the insertion of the water pipe 7. A water receiving tank 13 is arranged below the rotating platform 6 to store the leaked water.

[0018] On both sides of one of the water pipes 7 at an appropriate height, eccentric rotating blades 8 are arranged inside. The rotating shaft of the eccentric rotating blade 8 extends outside the water pipe 7, and an internal gear 10 is arranged on the rotating shaft of the eccentric rotating blade. Fans 11 are arranged on both sides of the rotating platform 6 through fixing blocks. The rotating shaft of the fan 11 passes through the fixing block, and an external gear 12 meshing with the internal gear 10 is arranged at the other end of the rotating shaft. The external gear 12 is driven by the internal gear 10 to drive the fan blades to rotate for cooling. Among them, due to the large diameter of the fan 11, a cut groove can be arranged on the rotating platform 6 so that there can be a rotating space on the side of the fan 11 close to the rotating platform 6. And the fan blades of the fan 11 are arranged inward according to the rotating directions on both sides, so that the wind direction driven by the fan 11 is inward.

[0019] This specific embodiment is only an explanation of the present utility model, and it is not a limitation of the present utility model. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
