Description

Technical Field

[0001] The utility model relates to the technical field of barium carbonate preparation, in particular to a centrifugal steam compression device for the production of electronic-grade barium carbonate. Background Technique

[0002] Electronic-grade barium carbonate is mainly used in the manufacture of electronic components, such as capacitors, PTC thermistors and positive temperature coefficient thermistors, etc. These components play a key role in the electronics industry and are crucial for ensuring the performance and stability of electronic devices. In addition, electronic-grade barium carbonate is also used in the manufacture of optical glass, cathode ray tube glass and barium magnetic materials, etc. These materials are widely used in various electronic devices, improving the performance and reliability of the devices. With the continuous development of the electronics industry, the demand for high-purity and high-value-added electronic-grade barium carbonate is increasing continuously, which also promotes the growth of the electronic-grade barium carbonate market.

[0003] In the process of preparing electronic-grade barium carbonate, it is necessary to use a centrifugal steam device to compress and purify it. However, in actual applications, we found that since the barium carbonate to be centrifugally compressed inevitably contains a small amount of barium hydroxide, it affects the purity of the barium carbonate product; and because barium hydroxide and barium carbonate are difficult to fuse with each other, it will also cause some agglomerates to be generated in the centrifugally compressed barium carbonate. These agglomerates are mainly composed of barium hydroxide, but also contain a lot of barium carbonate, which further increases the difficulty of subsequent treatment and reduces the product quality. Therefore, it is necessary to optimize the pretreatment of the existing centrifugal steam compression device. Summary of the Utility Model

[0005] Therefore, the purpose of the utility model is to provide a centrifugal steam compression device for the production of electronic-grade barium carbonate, so as to solve the problems in the above-mentioned background technique that in the existing process of preparing electronic-grade barium carbonate, since the barium carbonate to be centrifugally compressed inevitably contains a small amount of barium hydroxide, it affects the purity of the barium carbonate product, and increases the difficulty of subsequent treatment and reduces the product quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the accompanying drawings.

[0018] Secondly, the present utility model will be described in detail in combination with the schematic diagrams. When detailing the embodiments of the present utility model, for the convenience of description, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0019] In order to make the purpose, technical solution, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0020] Figure 1 - Figure 2 Shown is the schematic diagram of the entire structure of the centrifugal steam compression device for the production of electronic-grade barium carbonate of the present utility model. Please refer to Figure 1 - Figure 2, the centrifugal steam compression device for producing electronic-grade barium carbonate in this embodiment includes a mixing device 100. The input end of the mixing device 100 is connected to an infusion pipeline 200. One end of the infusion pipeline 200 far from the mixing device 100 is connected to a raw material tank 210. One end of the infusion pipeline 200 close to the mixing device 100 is connected to a gas transmission pipeline 300. One end of the gas transmission pipeline 300 far from the infusion pipeline 200 is connected to a carbon dioxide gas source 310. The output end of the mixing device 100 is connected to a collection tank 400. Among them, the mixing device 100 is used to perform gas-liquid mixing on the barium carbonate solution containing barium hydroxide and carbon dioxide gas input from the raw material tank 210 and the carbon dioxide gas source 310, and generate a barium carbonate solution that is easier to purify after the reaction.

[0021] The mixing device 100 is a gas-liquid mixing pump, and the output end of the gas-liquid mixing pump also has a diversion pipe 110 connected to the collection tank 400. A diaphragm metering pump 220 and a rotameter 230 are respectively arranged on the infusion pipeline 200, and the rotameter 230 is located in the output direction of the diaphragm metering pump 220. With the cooperation of the diaphragm metering pump 220 and the rotameter 230, the unit output of the barium carbonate stock solution output from the infusion pipeline 200 is more accurate and quantitative, avoiding incomplete reaction caused by imbalance in the ratio. In addition, the temperature of the barium carbonate stock solution in the raw material tank 210 can be controlled at about 70 °C. For example, the raw material tank 210 can adopt a constant temperature tank, so that sufficient reaction can be formed between barium hydroxide and carbon dioxide in the barium carbonate solution, which is beneficial to better purification later. An air pump 320 and a solenoid valve 330 are respectively arranged on the gas transmission pipeline 300, and the solenoid valve 330 is close to the junction of the gas transmission pipeline 300 and the infusion pipeline 200. The gas transmission pipeline 300 can pump the carbon dioxide gas source 310 into the mixing device 100 through the air pump 320. The solenoid valve 330 is an electromagnetic flow valve, which maintains a small opening and a large flow rate when opened, and sufficient pressure can prevent the liquid in the infusion pipeline 200 from flowing back into the gas transmission pipeline 300. Specifically, in this embodiment, one side of the bottom of the collection tank 400 also has a feed pipe 410 connected to the centrifugal compression and purification device, and a liquid pump 420 is arranged on the feed pipe 410. When in use, the barium carbonate solution containing barium hydroxide in the raw material tank 210 is quantitatively transported to the mixing device 100 through the infusion pipeline 200. At the same time, the carbon dioxide gas released from the carbon dioxide gas source 310 is quantitatively pumped to the output end of the infusion pipeline 200 through the gas transmission pipeline 300. Subsequently, the mixing device 100 quickly mixes the simultaneously entering barium carbonate solution and carbon dioxide gas. Barium hydroxide in the solution and carbon dioxide will react instantaneously after contact, generating pure barium carbonate and water, and then being sent to the collection tank 400 for temporary storage. When purification is required, it is then transported to the centrifugal steam compression equipment through the feed pipe 410 for dehydration washing and drying, and then a barium carbonate product with higher purity is obtained, reducing the subsequent processing difficulty and further ensuring the quality and efficiency.

[0022] Furthermore, it further includes a bottom plate 500 for fixedly installing the mixing device 100, the raw material tank 210, the carbon dioxide gas source 310 and the collection tank 400, and a total control unit of the device, i.e., a controller 600. By setting the bottom plate 500, the entire pretreatment device is positioned and installed to form a complete set of equipment. Through the controller 600, the staff can uniformly control and set the equipment, making it more convenient to use.

[0023] In summary, for the centrifugal steam compression device for producing electronic-grade barium carbonate in this embodiment, during use, the barium carbonate solution containing barium hydroxide in the raw material tank 210 is quantitatively transported to the mixing device 100 through the infusion pipeline 200. At the same time, the carbon dioxide gas released from the carbon dioxide gas source 310 is quantitatively pumped to the output end of the infusion pipeline 200 through the gas transmission pipeline 300. Subsequently, the mixing device 100 quickly mixes the simultaneously entering barium carbonate solution and carbon dioxide gas. The barium hydroxide in the solution will react instantaneously with the carbon dioxide after contact, generating pure barium carbonate and water, which are then sent to the collection tank 400 for temporary storage. When purification is required, it is further transported to the centrifugal steam compression equipment through the feed pipe 410 for dehydration washing and drying, and then a barium carbonate product with higher purity is obtained.
