Description

Technical Field

[0001] The utility model relates to the technical field of crucible anti-falling, in particular to a crucible receiving device capable of preventing material blocks from falling. Background Art

[0002] Tantalum is a rare transition metal. Tantalum is hard and highly corrosion-resistant. It is widely used in the manufacture of high-strength alloy steel or superalloy or carbide reinforced tools. Tantalum's excellent corrosion resistance means that it can be used to manufacture chemical process equipment and medical equipment and implants. Electron beam melting refers to a vacuum melting method that converts the kinetic energy of a high-speed electron beam into thermal energy as a heat source for metal melting under high vacuum. Electron beam melting needs to be maintained in a high vacuum environment to work properly. For the production of tantalum oxide, tantalum plates or ingots are used as the initial products, and tantalum oxide or tantalum carbide is obtained after processing in an electron beam melting furnace to meet subsequent manufacturing needs. Crucibles are generally used in electron beam melting furnaces to melt tantalum plates or ingots. Crucibles are generally used in vacuum furnaces to complete the oxidation of tantalum plates or ingots.

[0003] During the oxidation process of metal tantalum plates or tantalum ingots, the feed track transports the material into the vacuum furnace body, and then the material falls into the crucible body. However, due to a certain gap between the feed track and the crucible body, on the one hand, the material is easy to fall directly from the two side walls of the crucible body into the vacuum furnace body, and on the other hand, it is easy to transfer inertia and rush out of the crucible body directly along the feed track, that is, directly fall directly into the vacuum furnace body along the straight transmission path of the feed track, which ultimately reduces the amount of material entering the crucible body for oxidation processing, which not only affects the content of material oxidation processing, but also causes unnecessary waste of material.

[0004] Therefore, it is necessary to invent a crucible receiving device that can prevent material blocks from falling to solve the above problems. Summary of the invention

[0005] In order to address the deficiencies of the prior art, the purpose of the utility model is to provide a crucible receiving device that can prevent material blocks from falling. This solves the problem in the prior art that there is a certain gap between the feed track and the crucible body, which, on the one hand, makes it easy for the material to fall directly from the two side walls of the crucible body into the vacuum furnace body; on the other hand, it is easy to transmit inertia and directly rush out of the crucible body along the feed track, that is, directly fall directly into the vacuum furnace body along the straight transmission path of the feed track, ultimately reducing the amount of material entering the crucible body for oxidation processing, which not only affects the content of the material for oxidation processing, but also causes unnecessary waste of material.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0007] The top of the positioning flange ring plate is extended to form a flange abutment plate which can be detachably connected with the positioning flange ring plate, and the top of the positioning flange ring plate is extended to form a flange abutment plate which can be detachably connected with the positioning flange ring plate.

[0008] As a preferred solution of the utility model, a sliding column is provided in the center of the side plate for horizontal sliding, the sliding plate is detachably mounted on one end of the sliding column close to the crucible body, the other end of the sliding column is connected with an anti-slip ring, and the spring is sleeved on the part of the sliding column located between the sliding plate and the side plate.

[0009] As a preferred solution of the utility model, the top surface of the annular mounting plate abuts against an annular vertical plate at a position away from the crucible body, and the annular wedge baffle abuts against a side wall of the annular vertical plate close to the crucible body.

[0010] As a preferred solution of the present invention, the two side vertical plates are respectively abutted against two end portions of the annular vertical plate.

[0011] As a preferred solution of the utility model, a circular slot is provided at the center of the bottom side of the peripheral side wall of the furnace body, and the placement cartridge is removably inserted into the circular slot. A card plate is clamped on the inner peripheral side wall of the furnace body, and a slot is provided at the center of the card plate. The placement cartridge is removably inserted into the slot.

[0012] As a preferred solution of the utility model, support plates are connected to symmetrical positions on the bottom surface of the clamping plate, and the bottom ends of the two support plates are detachably abutted against the inner peripheral side wall of the furnace body.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] In the utility model, the feed track enters the furnace body from the feed port, and the crucible body can be detachably inserted into a placement cartridge at the center position of the furnace body. On both sides of the path of the material from the feed track to the receiving port of the crucible body, the two slides on both sides can be continuously squeezed outward according to the size of the material, thereby compressing the spring. On the one hand, the material is kept in the direction of the center line of the feed track and transmitted to the receiving port of the crucible body under the elastic limit of the two slides and the spring, and the side wedge baffle can prevent the material from falling from the gap on both sides. On the other hand, the material is reduced under the elastic limit of the two slides and the spring, thereby reducing the inertia of the material transmitted from the feed track. There is a risk that the material will directly fall into the furnace body along the straight transmission path of the feed track, and the annular wedge baffle at the end is used to block the material at the end of the straight transmission path to avoid the risk of falling. At the same time, the annular wedge baffle and the side wedge baffle have a certain slope close to the side wall of the crucible body, so that the passing material moves toward the receiving port of the crucible body under the influence of the slope, and finally avoids the problem of the material falling from the gaps on both sides and the end gaps, realizes the prevention of material falling, ensures the accuracy of the amount of material entering the crucible body for oxidation processing, thereby avoiding affecting the content of the material oxidation processing, and avoiding the problem of unnecessary waste of material.
