Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic aluminum material conveying systems, specifically a fluorine-loaded alumina conveying system. Background Technology

[0002] The alumina material used in the aluminum electrolysis workshop is mostly fluorinated alumina, which is produced by adsorbing hydrogen fluoride from the flue gas in the cleanroom through the dust collector system. The fluorinated alumina changes compared to alumina crystals, with finer particles and a stickier material. The fluorinated alumina material is conveyed by a pneumatic conveying device to the discharge pipe above the silo, and then falls into the silo after being distributed by a distribution plate. After being distributed by the distribution plate, most of the coarse material falls to the center of the silo, while most of the fine material falls to the silo wall away from the center. This causes the stickier fine material to accumulate together, blocking the material in the silo and making it difficult to discharge. Utility Model Content

[0003] The main purpose of this utility model is to provide a fluorine-loaded alumina conveying system to solve the problem in the prior art where, after the material is distributed by the material distribution plate above the silo in the aluminum electrolysis workshop, the sticky fine material accumulates together, causing blockage in the silo and making it difficult to discharge the material.

[0004] To achieve the above objectives, this utility model provides a fluorine-loaded alumina conveying system, including a silo and a discharge pipe located above the silo. A distribution chamber is fixedly connected to the bottom of the discharge pipe. Multiple chutes 1 and chutes 2 are evenly arranged on the bottom side wall of the distribution chamber. Chutes 1 and chutes 2 are staggered, and the discharge ends of chutes 1 and chutes 2 are inclined downward. The length of chutes 1 is greater than the length of chutes 2.

[0005] Furthermore, the upper part of the silo is a cylinder, and the distance from the discharge end of chute one to the center of the cylinder is two-thirds of the cylinder radius; the distance from the discharge end of chute two to the center of the cylinder is one-third of the cylinder radius.

[0006] Furthermore, the bottom ends of sluices one and two are located inside the silo.

[0007] Furthermore, the lower part of the material distribution chamber is an air chamber 1, and the upper part is a material chamber 1. An airflow distribution plate 1 is provided between the air chamber 1 and the material chamber 1. An air supply pipe 1 is connected to the air chamber 1.

[0008] Furthermore, both chute one and chute two are pneumatic chutes. The lower part of the pneumatic chute is air chamber two, and the upper part is material chamber two. An airflow distribution plate two is provided between air chamber two and material chamber two. Air chamber two is connected to air supply pipe two.

[0009] This invention uses staggered chutes one and two, with the length of chutes one being greater than the length of chutes two, to ensure that the distance from the discharge port of the chutes to the center of the silo varies, thus making the material fall into the silo more evenly.

[0010] This invention, by setting up an air chamber, a material chamber, an airflow distribution plate, and a pneumatic chute, can both disperse and dry the material, preventing it from sticking and clogging. Attached Figure Description

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] like Figures 1 to 2 As shown, according to an embodiment of the present invention, a fluorine-loaded alumina conveying system is provided, including a silo 1 and a discharge pipe 2 located above the silo. A distribution chamber 3 is fixedly connected to the bottom of the discharge pipe 2. A plurality of chutes 1 4 and chutes 2 5 are evenly arranged on the bottom side wall of the distribution chamber 3. Chutes 1 4 and chutes 2 5 are staggered, and the discharge ends of chutes 1 4 and chutes 2 5 are inclined downward. The length of chutes 1 4 is greater than the length of chutes 2 5.

[0017] The upper part of the silo 1 is a cylinder 101. The distance from the discharge end of the first chute 4 to the center of the cylinder 101 is two-thirds of the radius of the cylinder 101; the distance from the discharge end of the second chute 5 to the center of the cylinder 101 is one-third of the radius of the cylinder 101.

[0018] The bottom ends of chute 1 (4) and chute 2 (5) are located inside silo 1.

[0019] In some embodiments, the lower part of the material distribution chamber 3 is an air chamber 301, the upper part is a material chamber 302, and an airflow distribution plate 303 is provided between the air chamber 301 and the material chamber 302; the air chamber 301 is connected to an air supply pipe 304.

[0020] In some embodiments, both chute 1 4 and chute 2 5 are pneumatic chutes. The lower part of the pneumatic chute is air chamber 2 6 and the upper part is material chamber 2 7. An airflow distribution plate 2 8 is provided between air chamber 2 6 and material chamber 2 7. Air chamber 2 6 is connected to an air supply pipe 2 9.

[0021] The conveying process of fluorine-loaded alumina is as follows: the material is conveyed to the discharge pipe 2 by a pneumatic conveying device, falls into the distribution chamber 3 through the discharge pipe 2, and is then distributed from the distribution chamber 3 to chute 1 4 and chute 2 5. Finally, it is discharged into the silo 1 through the discharge ports of chute 1 4 and chute 2 5.

[0022] After the material exits the discharge port, finer materials float a longer distance laterally, while coarser materials float a shorter distance laterally. In existing technologies, most fine materials float to the silo wall and fall after exiting the discharge port, while most coarser materials fall before reaching the silo wall, causing stickier fine materials to accumulate on the silo wall. The above embodiment, by setting up staggered chutes 1 4 and chutes 2 5, with the length of chutes 1 4 being greater than the length of chutes 2 5, ensures that the distance from the discharge port of the chutes to the silo center and the silo wall varies. After the material exits the chutes, some coarser materials can also float to the silo wall and fall, resulting in more even distribution of material into the silo and preventing stickier fine materials from accumulating on the silo wall and causing blockages.

[0023] In some embodiments, by setting up an air chamber 301, a material chamber 302, an airflow distribution plate 303, and a pneumatic chute, the material can be dispersed and dried, preventing the material from sticking and clogging.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
