Description

Technical Field

[0001] The utility model relates to the technical field of vanadium-nitrogen alloy processing, and more specifically to a feeding hopper for forming vanadium-nitrogen alloy blanks. Background Art

[0002] The process flow of manufacturing billets for producing vanadium-nitrogen alloys is generally as follows: pre-treating the raw materials to obtain vanadium oxide powder and reducing agent with particle sizes meeting the requirements; measuring the vanadium oxide powder and reducing agent separately, and mixing the vanadium oxide powder and reducing agent in a certain ratio; adding a binder to the mixture of the vanadium oxide powder and the reducing agent and then fully mixing; using a molding machine to press the mixture of the vanadium oxide powder, the reducing agent and the additive into billets of the required shape and size, wherein the powdered material before molding is conveyed to the feed port of the molding machine through a material conveying device, and the material is transported to the feed hopper in the feed port, and the material automatically falls from the feed hopper by relying on the gravity of the material, so as to mold the billet.

[0003] After searching, the utility model patent with announcement number CN204095183U discloses a feed hopper for forming vanadium-nitrogen alloy billets, including a ball press body, a feed port is provided at the upper end of the ball press body, a feed hopper is movably connected to the feed port, a vibration motor connected to the feed hopper is provided at the feed port, and a material conveying device placed obliquely downward is provided at the upper end of the feed port, the material conveying device includes a material trough and a spiral shaftless conveying roller installed in the material trough; in this patent, the feed hopper and the feed port are movably connected, and the feed hopper is connected to the vibration motor, the vibration motor will drive the feed hopper to shake, so that the material in the feed hopper is easy to fall, reducing labor intensity; at the same time, the material conveying device adopts the mutual cooperation of the material trough and the spiral shaftless conveying roller to convey the material, which reduces the spillage of the material and also protects the environment.

[0004] However, the above patents still have the following shortcomings: relying solely on the vibration motor to shake the feed hopper cannot ensure that all materials fall, some powders may be firmly attached to the wall of the feed hopper, and the transported powders are easily lifted up when they fall into the feed hopper, resulting in waste of materials and affecting the surrounding environment. For this reason, we propose a feed hopper for forming vanadium nitrogen alloy billets. Utility Model Content
