Description

Technical Field

[0001] This utility model relates to the technical field of ultra-dense phase pipeline flow regulation equipment, specifically a fluid transport network branch flow regulation device. Background Technology

[0002] The dense-phase conveying technology was first successfully developed in France and is used in aluminum electrolysis cell series feeding. Its most significant differences are twofold: first, a special exhaust structure allows for the timely discharge of fluidized air; second, the material almost fills the entire cross-section of the chute, resulting in a significant conveying capacity despite the low flow velocity. Furthermore, this technological breakthrough has removed many spatial limitations for achieving long-distance fluidized bed conveying of alumina. Dense-phase conveying utilizes the transformation of material into a two-phase (solid-gas) fluid after fluidization, and then, based on the principle of fluid dynamic and static pressure energy conversion, the material is conveyed within the conveying trough. According to the principle of dense-phase conveying, the role of low-pressure air is only to fluidize the alumina bed, not to propel the material forward; therefore, the required air pressure is very low, and ordinary centrifugal fans can meet the requirements. Because the required air velocity and pressure to maintain the fluidization of the alumina bed are very low, this technology has low energy consumption, a simple system structure, and low manufacturing cost. The entire system has no moving mechanical parts, ensuring reliable operation and minimal daily maintenance workload and costs. It supplies material to each point of use based on internal pressure balance, requiring no auxiliary control system. These characteristics are unparalleled and cannot be easily achieved by any other conveying technology. However, due to various reasons such as unstable bottom air pressure in the ultra-dense phase pipeline, internal wear in the ultra-dense phase pipeline, or uneven installation of the ultra-dense phase pipeline, uneven material supply occurs in the Y-structure branches during material flow. This results in the feed hopper of the faster-feeding branch being full and blocked, while the feed hopper of the slower-feeding branch is empty, affecting feeding efficiency and system stability. Therefore, we propose a fluid conveying network branch flow adjustment device. Summary of the Invention

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-7 This utility model provides a technical solution: a fluid transport network branch flow adjustment device, including a Y-shaped ultra-dense phase pipeline 1. The interior of the ultra-dense phase pipeline 1 is divided into an upper material chamber 3 and a lower air chamber 4 by a permeable plate 2. Exhaust columns are distributed at intervals above the material chamber 3, and a push-type quick-opening door 5 is installed on the exhaust columns. A material distribution mechanism 6 is provided inside the ultra-dense phase pipeline 1. The material distribution mechanism 6 is a Y-shaped baffle. A rotating shaft 7 is connected to the middle of the material distribution mechanism 6. A connecting shaft 10 is provided at one end of the material distribution mechanism 6, and the connecting shaft 10 is movably installed in a limiting frame 11.

[0021] By setting a material distribution mechanism 6 (Y-type baffle) inside the Y-type ultra-dense phase pipeline 1, which can rotate around the rotating shaft 7 through the cooperation of the rotating shaft 7 and the connecting shaft 10, the angle of the material distribution mechanism 6 in the Y-type branch can be adjusted, thereby changing the material flow cross-sectional area of ​​each branch, solving the problem of uneven material supply in the Y-type branch, and realizing precise adjustment of the material quantity in each branch.

[0022] In the above scheme, the inlet end of the ultra-dense phase pipeline 1 is connected to the bottom of the fluorine-loaded silo, and a branch of the ultra-dense phase pipeline 1 is connected to the feed tank of the electrolytic cell. This connection method ensures that the fluorine-loaded material is continuously transported from the silo to the feed tank of the electrolytic cell through the Y-shaped branch of the ultra-dense phase pipeline 1. Combined with the adjustment function of the distribution mechanism 6, the feeding speed of each branch can be balanced, avoiding clogging or shortage of material in the feed tank.

[0023] In the above scheme, the material distribution mechanism 6 has a symmetrical structure with the rotating shaft 7 as the center. The symmetrical structure makes the material distribution mechanism 6 more balanced in controlling the material quantity on both sides of the Y-shaped branch when rotating and adjusting, further improving the material distribution accuracy and preventing adjustment deviations caused by structural eccentricity.

[0024] In the above scheme, the surface of the dispensing mechanism 6 is coated with a wear-resistant coating, which is a ceramic coating or a tungsten carbide coating. The wear-resistant coating can significantly reduce the wear caused by long-term contact between the dispensing mechanism 6 and the material, extend the service life of the device, and reduce the problem of uneven material supply caused by component wear.

[0025] In the above scheme, the end of the rotating shaft 7 extends to the outside of the ultra-dense phase pipeline 1 and is connected to a knob 8. The rotating shaft 7 is rotatably engaged within the limiting plate 9. The knob 8 allows the operator to directly adjust the angle of the dispensing mechanism 6 from the outside of the pipeline, and the limiting plate 9 ensures the stability of the rotating shaft 7 during rotation, achieving convenient and reliable material quantity adjustment.

[0026] In the above scheme, a sealing ring is provided between the push-button quick-opening door 5 and the opening of the ultra-dense phase pipeline 1. The sealing ring can prevent air leakage at the opening of the exhaust column, ensure stable air pressure in the material chamber 3, and avoid the decrease in material fluidization effect and loss of feeding efficiency due to air leakage.

[0027] Working principle:

[0028] In this fluid transport network branch flow regulating device, the ultra-dense phase pipeline 1 is divided into a lower air chamber 4 and an upper material chamber 3 by a permeable plate 2. The air chamber 4 introduces low-pressure air to fluidize the alumina material in the material chamber 3, and the exhaust column is used to discharge excess airflow and maintain the pressure balance in the material chamber 3.

[0029] The material distribution mechanism 6 (Y-shaped baffle) is installed at the bifurcation center of the Y-shaped pipe via a rotating shaft 7. The operator rotates the outer knob 8, which drives the rotating shaft 7 to rotate, causing the material distribution mechanism 6 to rotate around the rotating shaft 7. At the same time, the connecting shaft 10 slides within the limiting frame 11, assisting the material distribution mechanism 6 in adjusting its angle, changing the flow cross-sectional area on both sides of the Y-shaped branch, and precisely controlling the material distribution of each branch.

[0030] The wear-resistant coating on the surface of the feeding mechanism 6 reduces material impact and wear, and the sealing ring of the push-type quick-opening door 5 prevents air leakage, ensuring stable air pressure and fluidization effect, and guaranteeing uniform feeding and long-term reliable operation of the system.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
