Abstract
Description
Technical Field
[0001] This application relates to the field of storage silo technology, and more specifically, to a carbon black storage silo. Background Technology
[0002] In recent years, carbon black powder, due to its high calorific value and wide availability, has been increasingly explored as a fuel to replace raw coal in the grinding process of cement production. This aims to reduce production costs and pollutant emissions, aligning with the development trend of green production.
[0003] However, carbon black, as a powdery substance, has strong hygroscopic properties. During storage, it easily absorbs moisture due to high ambient humidity, causing the particles to stick together and form clumps. Clumped carbon black not only reduces its performance but also causes blockage at the discharge port, severely affecting discharge efficiency. At the same time, traditional carbon black storage silos usually lack effective gas regulation devices, and the moisture inside the silo cannot be discharged in time, further aggravating the problem of carbon black becoming damp and clumping.

The multiple jet branch pipes are evenly distributed circumferentially on the annular main pipe. One end of each jet branch pipe is connected to the annular main pipe, and the other end of each jet branch pipe extends into the chamber.

[0028] like Figure 1 and Figure 2 As shown, this application provides a carbon black storage silo, including a silo body 1 with a feed inlet 11 at the top and a discharge outlet 12 at the bottom. A feed valve 13 is provided at the feed inlet 11, and a discharge valve 14 is provided at the discharge outlet 12. A gas-thermal injection assembly 2 is provided at the lower part of the silo body 1. The gas-thermal injection assembly 2 includes a high-pressure air pipe 21, a hot air pipe 22, an annular main pipe 23, a high-pressure air control valve 24, a hot air control valve 25, and multiple injection branch pipes 26. The multiple injection branch pipes 26 are evenly distributed circumferentially on the annular main pipe 23, and one end of each injection branch pipe 26 is connected to the annular main pipe 23. The main pipe 23 is connected to the main pipe, and the other end of the jetting branch pipe 26 extends into the chamber 1. A nozzle is provided at the end of the jetting branch pipe 26 extending into the chamber 1. The high-pressure air pipe 21 and the hot air pipe 22 are respectively connected to the main pipe 23. A high-pressure air control valve 24 is located on the high-pressure air pipe 21, and a hot air control valve 25 is located on the hot air pipe 22. An exhaust port 15 is provided at the top of the chamber 1, and an exhaust valve 16 is provided at the exhaust port 15. In use, the high-pressure air pipe 21 is connected to a high-pressure air source, the hot air pipe 22 is connected to a hot air source, and the exhaust port 15 is connected to a filter. Carbon black is received and stored through the top feed inlet 11 under the control of the feed valve 13, and discharged through the bottom discharge outlet 12 under the control of the discharge valve 14. When dehumidification is required, the feed valve 13, discharge valve 14, and high-pressure air control valve 24 are closed, while the hot air control valve 25 and exhaust valve 16 are opened. Hot air enters the annular main pipe 23 through the hot air pipe 22, and then is sprayed into the silo 1 through the nozzles at the ends of each spray branch pipe 26 to remove moisture from the carbon black. The humid gas is discharged through the exhaust port 15 to the filter and then discharged. When unloading, the feed valve 13... Hot air control valve 25 and exhaust valve 16 are closed, while high-pressure gas control valve 24 and discharge valve 14 are opened. High-pressure gas enters the annular main pipe 23 through high-pressure gas pipe 21, and then is sprayed into the silo through nozzles at the ends of each spray branch pipe 26 to loosen the carbon black and ensure smooth discharge. By setting up the gas-heat spray assembly 2, hot air can be flexibly selected to dry the carbon black to prevent it from getting damp and clumping, or high-pressure gas can be selected to loosen the carbon black in the silo to ensure smooth discharge. The exhaust port 15 works in conjunction with the gas-heat spray assembly 2 to promptly remove moisture from the silo and optimize the storage environment.
[0029] like Figure 1 and Figure 2 As shown, the nozzles are divided into swirling nozzles 4 and direct-shot nozzles 5, which are distributed alternately. The bottom of the bin 1 is conical, and the discharge port 12 is located at the center of the bottom of the bin 1. The direct-shot nozzles 5 are tilted downwards and their nozzles point towards the conical wall of the bin 1. Specifically, the swirling channel of the swirling nozzle 4 is equipped with swirling vanes, and the direct-shot nozzle 5 is a direct-blowing cylinder structure. Both are existing technologies and will not be described in detail here. When loosening or dehumidifying, the airflow ejected by the swirling nozzle 4 forms a rotating flow field, and the airflow ejected by the direct-shot nozzle 5 forms a jet. The rotating airflow can loosen the carbon black in the bin 1 as a whole, and the jet airflow strengthens the loosening of easily clogged areas. The alternating swirling and direct-shot nozzles 5 work together to improve the loosening or dehumidification effect on the carbon black.
[0030] like Figure 1 As shown, a humidity sensor 6 is installed on the inner top of the chamber 1 to detect the humidity inside the chamber 1. The humidity sensor 6 is electrically connected to a controller (not shown in the figure). The controller is electrically connected to the hot air control valve 25, the exhaust valve 16, the high-pressure air control valve 24, the feed valve 13, and the discharge valve 14. The humidity sensor 6 detects the humidity information inside the chamber in real time and transmits the detection data to the controller. After receiving the humidity data, the controller controls the hot air control valve 25 and the exhaust valve 16 in conjunction with the preset humidity threshold. When the humidity exceeds the standard, the controller controls the hot air control valve 25 and the exhaust valve 16 to open for dehumidification and discharge moisture.
[0031] like Figure 1 As shown, the chamber 1 is equipped with a stirring assembly 7, and the top of the chamber 1 is equipped with a drive motor 8 for driving the stirring assembly 7 to rotate. The drive motor 8 is electrically connected to the controller. The controller controls the drive motor 8 to start, and the drive motor 8 drives the stirring assembly 7 to rotate, stirring the carbon black in the chamber 1, so that the carbon black can fully contact the airflow sprayed by the gas thermal blowing assembly 2. Especially during dehumidification, the dehumidification effect and dehumidification efficiency can be further improved.
[0032] like Figure 1 As shown, the stirring assembly 7 includes a stirring shaft 71 and multiple stirring rods 72. The stirring shaft 71 is rotatably disposed inside the chamber 1, and the upper end of the stirring shaft 71 extends outside the chamber 1 and is connected to the output shaft of the drive motor 8. The multiple stirring rods 72 are fixedly mounted on the stirring shaft 71 at equal intervals along the axial direction of the stirring shaft 71. Specifically, a bearing is provided at the connection between the stirring shaft 71 and the chamber 1. The stirring shaft 71 is driven to rotate by the drive motor 8, which drives the stirring rods 72 to stir the carbon black in the chamber 1.
[0033] like Figure 1 As shown, the high-pressure gas control valve 24 and the hot air control valve 25 are both solenoid valves, while the feed valve 13, the discharge valve 14 and the exhaust valve 16 are all electric butterfly valves, which facilitates linkage control with the controller.
[0034] like Figure 1 As shown, the inner wall of the silo 1 is provided with an anti-stick coating (not shown in the figure). The anti-stick coating can effectively prevent carbon black from adhering and accumulating on the inner wall of the silo 1, and further improve the smoothness of discharge in conjunction with the stirring and blowing action.
[0035] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
