Description

Technical Field

[0001] This utility model relates to the field of electrolytic manganese production technology, specifically to an automatic oxygen supply device for selenium dioxide production. Background Technology

[0002] Oxygen supply plays a crucial role in the production of selenium dioxide, primarily for the following purposes:

[0003] As an oxidizing agent, selenium dioxide is often involved in the oxidation of selenium-containing raw materials during the preparation of selenium dioxide. Oxygen has strong oxidizing properties and can oxidize low-valence selenium compounds, such as selenides or elemental selenium, to higher-valence selenium dioxide, thus driving the chemical reaction toward the formation of the target product. It is one of the core elements for the smooth progress of the reaction.

[0004] Maintaining stable reaction conditions: A sufficient oxygen supply helps maintain a suitable oxidizing atmosphere within the reaction system, ensuring the reaction proceeds continuously in a stable environment. This not only improves the efficiency of selenium dioxide formation but also reduces side reactions, enhancing the purity and quality of the product.

[0005] Ensuring safe production: A proper oxygen supply can prevent incomplete reactions due to oxygen deficiency, prevent the accumulation of unreacted raw materials, and reduce potential safety risks. At the same time, a stable oxidation environment can reduce the occurrence of abnormal reactions, ensure the safe operation of production equipment, and guarantee a smooth and orderly production process.

[0006] CN222795175U discloses a selenium dioxide production device, comprising: a reactor, a feeding mechanism, an installation shaft, rake rods, a discharge net, a drive mechanism, an oxygen supply mechanism, and an exhaust pipe. The feeding mechanism is located above the reactor, and its discharge end is connected to the reactor. The installation shaft is located inside the reactor, with one end rotatably connected to the inner wall of the reactor. Multiple rake rods are provided, each connected to the installation shaft via two connecting rods. The drive mechanism of this invention rotates the rake rods and the discharge net together, rakeing up the selenium powder accumulated at the bottom of the reactor. After being raken up, the selenium powder is buffered by the discharge net and falls back to the bottom of the reactor. During the descent, the selenium powder comes into contact with oxygen, greatly increasing the contact area and contact time between the selenium powder and oxygen, accelerating the reaction process, and improving production efficiency.

[0007] The problem with the above-mentioned selenium dioxide production device is that:

[0008] Uneven oxygen distribution: The original patent used a fixed gas distribution pipe for unidirectional oxygen supply. The contact between oxygen and selenium powder depended on random diffusion, resulting in low reaction efficiency and insufficient local reaction.

[0009] The selenium powder dispersion effect is poor: relying solely on the rake rod and the drop net to sprinkle selenium powder, the material tends to accumulate at the bottom of the reactor, making it difficult for oxygen to penetrate into the accumulation layer. Utility Model Content

[0010] This invention proposes an automatic oxygen supply device for selenium dioxide production, which solves the problems of uneven oxygen distribution and poor selenium powder dispersion in the prior art.

[0011] The technical solution of this utility model is as follows: An automatic oxygen supply device for the production of selenium dioxide includes a reaction cylinder and an oxygen conveying mechanism disposed at the bottom of the reaction cylinder. An annular oxygen delivery component is disposed on the side of the reaction cylinder to cooperate with the oxygen delivery mechanism to deliver oxygen into the reaction cylinder. A cylinder cover is mounted on the top of the reaction cylinder. A feeding component is disposed on one side of the cylinder cover to uniformly deliver selenium powder into the reaction cylinder. A linkage scraping component is disposed in the center of the cylinder cover to stir the selenium powder and cooperate with the annular oxygen delivery component to complete the reaction.

[0012] Preferably, the feeding assembly includes a feeding seat, which is fixedly connected to the cylinder cover, and the bottom of the feeding seat is located inside the reaction cylinder and is connected to the reaction cylinder.

[0013] Preferably, the feeding assembly further includes a feeding port, which is fixedly connected to the side of the feeding base and communicates with the interior of the feeding base.

[0014] Preferably, the feeding assembly further includes a motor, which is fixedly mounted on the top of the feeding base, and the feeding assembly further includes a partition, which is fixedly connected to the middle of the feeding base.

[0015] Preferably, the feeding assembly further includes a first rotating shaft, which is rotatably connected to the middle of the partition plate. The top of the first rotating shaft is fixedly connected to the motor output end. The feeding assembly also includes a spiral feeding rod, which is fixedly connected to the bottom of the first rotating shaft.

[0016] Preferably, the linkage scraping assembly includes a sleeve, which is fixedly connected to the middle of the cylinder cover.

[0017] Preferably, the linkage scraping assembly further includes a second rotating shaft, which is rotatably connected to the middle of the sleeve. The linkage scraping assembly also includes scraping blades, which are arranged in annular oblique directions inside the reaction cylinder, and each scraping blade is fixedly connected to the second rotating shaft.

[0018] Preferably, the linkage scraping assembly further includes a first synchronous wheel, which is fixedly connected to the middle of the first rotating shaft.

[0019] Preferably, the linkage scraping assembly further includes a second synchronous pulley, which is fixedly connected to the upper part of the second rotating shaft. The linkage scraping assembly also includes a synchronous belt, which is sleeved on the outside of the first and second synchronous pulleys, and the synchronous belt is meshed with the first and second synchronous pulleys for transmission.

[0020] Preferably, the annular oxygen delivery assembly further includes a delivery chamber fixedly connected in an annular shape to the side of the reaction cylinder. Each delivery chamber is connected to the interior of the reaction cylinder, and a guide channel is fixedly connected to the bottom of each delivery chamber. Each guide channel is connected to the oxygen delivery mechanism at the end away from the delivery chamber.

[0021] The beneficial effects of this utility model are as follows: 1. The annular oxygen delivery assembly achieves multi-directional uniform oxygen supply:

[0022] Improvements: An annular delivery chamber and a flow channel are installed on the side of the reaction cylinder, allowing oxygen to enter the reaction zone evenly from multiple directions, thus covering a wider area.

[0023] Advantages: It overcomes the limitations of unidirectional oxygen supply, allowing for more complete contact between oxygen and selenium powder, and significantly improving reaction efficiency.

[0024] II. Dynamic mixing of selenium powder by the linkage scraper assembly:

[0025] Improvement: The scraper blades are driven to rotate by a synchronous belt, which forces the selenium powder to be dispersed and fully mixed with oxygen.

[0026] Advantages: Prevents selenium powder buildup, ensures oxygen penetration into the material, and results in a more thorough reaction. Attached Figure Description

[0042] The linkage scraping assembly 5 also includes a second rotating shaft 53, which is rotatably connected to the middle of the sleeve 52.

[0043] The linkage scraping assembly 5 also includes a first synchronous wheel 511, which is fixedly connected to the middle of the first rotating shaft 421.

[0044] The linkage scraping assembly 5 also includes a second synchronous pulley 512, which is fixedly connected to the upper part of the second rotating shaft 53. The linkage scraping assembly 5 also includes a synchronous belt 51, which is sleeved on the outside of the first synchronous pulley 511 and the second synchronous pulley 512.

[0049] Specifically, when the first rotating shaft 421 rotates, the first synchronous pulley 511 located outside the first rotating shaft 421 will rotate synchronously, and under the meshing transmission cooperation of the synchronous belt 51 and the second synchronous pulley 512, the second rotating shaft 53 located inside the second synchronous pulley 512 will rotate synchronously at the sleeve 52, and the scraper blades 531 distributed in a ring on the lower part of the outer side of the second rotating shaft 53 will rotate synchronously and disperse and scrape the selenium powder falling into the reaction cylinder 1.
