Description

Technical Field

[0001] The utility model relates to the technical field of bismuth needle drying devices, and specifically relates to a bismuth needle drying device. Background Technique

[0002] Bismuth is a relatively rare metallic element with a low melting point, high hardness, large density and stable properties. It can be used to make low-melting alloys for automatic shut-off devices or type metal alloys, can be made into oxides and used as additives in the ceramic and glass industries, and can also be made into compounds for use as drugs, with a wide range of applications. In China, bismuth metallurgy mostly produces bismuth ingots. When deep-processing bismuth, it needs to be crushed. Since metallic bismuth has a high hardness, crushing is not easy. In contrast, melting bismuth into bismuth needles of 2-3 cm greatly facilitates subsequent deep-processing, and can reduce a lot of workload in the production of bismuth compounds, bismuth products and additives.

[0003] For example, the patent document with the application number 201721595487.8 discloses a bismuth needle drying device. The utility model discloses a bismuth needle drying device, the structure of which includes a dryer, a housing, a passivation liquid tank, a spraying system, a hot air motor, a draft board and a bismuth needle inlet box. The dryer is provided with a housing, the surface of the housing is provided with a passivation liquid tank, the inside of the housing is provided with a spraying system, the passivation liquid tank is connected to the spraying system through the housing, a hot air motor is arranged below the housing, a draft board is fixedly arranged behind the hot air motor, and a bismuth needle inlet box is fixedly arranged on the surface of the housing. The bismuth needle drying device of the utility model can be used in cooperation with a spray head through the arranged spraying system with a passivation liquid tank, which is convenient for wrapping the surface of the bismuth needle to avoid excessive oxidation. By arranging a shaft rod with a feeding arc plate, it is convenient to increase the transmission capacity of the bismuth needle inlet box to avoid blockage and accumulation. The structure is simple and easy to implement. However, when placing the bismuth needles on the conveyor belt, if one bismuth needle is placed in sequence, the drying speed of the bismuth needles will be reduced, and if too many bismuth needles are fed, it will cause the bismuth needles to accumulate and affect the drying effect.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a bismuth needle drying device is proposed. Content of the Utility Model
