Description

Technical Field

[0001] This utility model relates to the fields of chemical equipment and environmental protection technology, specifically to a rotary drum ash removal system. Background Technology

[0002] Yellow phosphorus is a very important chemical raw material in my country, and it is commonly produced using the electric furnace method. This method involves mixing phosphate rock, silica, and coke in specific proportions and then feeding them into an electric furnace. The mixture undergoes a chemical reaction through electrode heating. The reaction process produces CO and incompletely reacted phosphorus mud. The CO can be used as fuel for further production in other workshops, while the phosphorus mud contains recoverable yellow phosphorus. This yellow phosphorus can be recovered by burning the mud in a rotary drum furnace and separating the mud and sand, thus improving the utilization rate of yellow phosphorus.

[0003] During the calcination of sludge and phosphorus in the rotary drum furnace, a large amount of phosphorus slag, commonly known as rotary drum ash, is produced. The temperature of the rotary drum ash is extremely high when it is first transferred from the furnace. In the hot summer, the physical exertion of workers removing the ash and pushing the carts is enormous, resulting in significant manpower consumption. Furthermore, due to production efficiency requirements, waiting for the rotary drum ash to cool to room temperature before transferring it back into the furnace is quite time-consuming and severely impacts production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a rotary drum ash removal system. This system realizes automated operation, and workers only need to operate the drum inlet and control device, which greatly reduces the input of manpower and high-intensity labor. At the same time, there is no need to wait for the ash in the drum to cool to room temperature before processing. The drum can operate continuously, which greatly improves production efficiency and effectively solves the problems of low efficiency, high labor intensity and many safety hazards in the existing technology.

[0005] This utility model is achieved through the following technical solution:

[0006] A rotary drum dust removal system, comprising:

[0007] A trough having a chamber for receiving high-temperature ash and slag discharged from a rotating drum;

[0008] The transport assembly includes an extraction device, the suction end of which is located in the chamber and the outlet end of which is located above the trench. The extraction device, driven by a drive device, lifts ash from the trench to an ash silo located at a higher position.

[0009] In this solution, the trough serves as the initial receiving section for high-temperature ash and slag, providing temporary storage space for subsequent processing. Its chamber design ensures that the ash and slag can be collected in an orderly manner, preventing scattering. The extraction device in the transport assembly is the key to realizing the transfer of ash and slag. Under the action of the drive device, it can overcome gravity and lift the ash and slag in the trough to the high-level ash silo. This changes the inefficient and dangerous operation method of traditional manual handling of ash and slag, lays the foundation for the automation of rotary drum ash treatment, effectively improves production efficiency, and reduces labor consumption and safety risks.

[0010] As a further technical solution for the rotary drum ash removal system, the ground trough also includes a vertical insert plate, which divides the chamber into at least two independent partial chambers, wherein the chamber where the suction end is located is located in the tail chamber of the partial chamber, and the chamber for receiving high-temperature ash is located in the head chamber of the partial chamber.

[0011] In this design, vertical insert plates divide the trench chamber into two parts, effectively preventing the newly discharged high-temperature ash from directly affecting the suction end of the extraction device. This ensures the extraction device operates in a relatively suitable temperature environment, reducing the risk of equipment damage due to high temperatures and extending its service life. Simultaneously, this partitioned design facilitates the orderly temporary storage and processing of ash at different stages, improving the stability and reliability of the entire system and making the ash treatment process more rational and efficient.

[0012] As a further technical solution for the rotary drum dust removal system, the vertical insert plate can be opened and closed via a control device.

[0013] In this solution, the opening and closing of the vertical baffle is achieved through a control device, greatly enhancing the system's flexibility and controllability. During the high-temperature ash receiving stage, the closed baffle ensures stable storage of the ash in the first chamber, preventing interference with subsequent processing stages. When the ash cools to a suitable temperature, the control device opens the baffle, allowing it to smoothly enter the tail chamber for extraction. This automated switching of the ash processing process effectively optimizes the workflow, reduces manual intervention, and further improves the overall efficiency and safety of the rotary drum ash removal system, ensuring stable system operation.

[0014] As a further technical solution for the rotary drum dust removal system, the vertical insert plate is a component made of high-temperature resistant material.

[0015] In this design, the baffle plate is constantly exposed to high temperatures during operation because the system needs to handle the high-temperature ash discharged from the drum. Using high-temperature resistant materials, such as nickel-based and cobalt-based superalloys, ensures that the baffle plate maintains its structural strength and stability under high temperatures, preventing deformation, damage, or chemical changes. This not only guarantees the baffle plate's effective compartmentalization function and maintains the orderly flow of ash treatment, but also reduces system downtime due to baffle plate failure, improving the reliability and durability of the entire drum ash removal system, lowering equipment maintenance costs, and ensuring long-term stable operation.

[0016] As a further technical solution for the rotary drum ash removal system, the extraction device includes an auger that lifts ash from the ground trough to an ash silo located at a higher level.

[0017] In this solution, the auger generates a continuous and stable axial thrust and lifting force on the ash slag through the rotation of its spiral blades. This overcomes the gravity and friction of the ash slag, efficiently and orderly lifting it from the trough to the high-level ash silo. Compared to other extraction methods, the auger's conveying process is more stable and continuous, effectively avoiding problems such as ash slag blockage or leakage. This ensures stable transmission of ash slag from the trough to the ash silo, guaranteeing the smooth operation and high efficiency of the entire ash removal system, and greatly improving the efficiency and effectiveness of the rotary drum ash treatment.

[0018] As a further technical solution for the rotary drum ash removal system, a transfer tool is also provided at the screw conveyor outlet, which transfers the ash and slag output from the screw conveyor outlet to the ash silo.

[0019] In this solution, the transfer tool plays a crucial connecting role, adapting to the discharge rhythm and ash characteristics of the auger outlet. It collects and organizes the ash output from the auger and transfers it to the ash silo in a stable and efficient manner. This effectively avoids problems such as ash scattering and uneven accumulation that might occur when the auger directly discharges material into the ash silo, ensuring the accuracy and orderliness of the ash as it enters the ash silo, and further optimizing the material transfer process of the entire rotary drum ash removal system.

[0020] As a further technical solution for the rotary drum ash removal system, the transfer tool is a trolley or a belt conveyor.

[0021] In this solution, the trolley is highly flexible and suitable for small- to medium-scale production scenarios or situations with complex site layouts. It can conveniently receive ash from the auger outlet at different locations and transport it to the ash silo as needed, offering advantages in space utilization and ease of operation. The belt conveyor, on the other hand, is suitable for large-scale continuous production. It can efficiently transfer ash from the auger outlet to the ash silo at a stable speed and with a large conveying capacity, greatly improving transportation efficiency and reducing the frequency and intensity of manual operation.

[0022] As a further technical solution for the rotary drum ash removal system, a flow guiding device is provided between the discharge port of the rotary drum and the ground trough, and the flow guiding device guides the high-temperature ash and slag discharged from the rotary drum into the ground trough.

[0023] In this solution, the high-temperature ash discharged from the rotary drum has a high temperature and a certain degree of fluidity. Without a flow guiding device, the ash may scatter outside the trough, causing material waste, polluting the surrounding environment, and potentially posing safety hazards to operators. The flow guiding device can accurately guide the high-temperature ash along a predetermined path into the trough, ensuring the efficiency and accuracy of ash collection and making the material input of the entire ash removal system more stable and reliable.

[0024] As a further technical solution for the rotary drum dust removal system, the flow guiding device is an inclined flow guiding plate or flow guiding groove.

[0025] In this design, the inclined structure utilizes the principle of gravity, allowing the high-temperature ash discharged from the drum to flow smoothly and quickly into the trench along the inclined surface of the guide plate or guide channel under its own weight. This design effectively improves the ash guiding efficiency, reduces the retention and accumulation of ash during the transfer process, and avoids problems such as blockage or overflow that may be caused by ash retention. The form of the guide plate or guide channel can be flexibly selected based on factors such as actual installation space and ash flow rate, while ensuring the guiding function.

[0026] As a further technical solution for the rotary drum ash removal system, the control device is electrically connected to the rotary drum, the vertical insert plate, the auger, and the transfer tool.

[0027] This solution precisely controls the timing of ash discharge from the rotary drum, the opening and closing of the vertical baffle, the operating speed and start / stop of the auger, and the material transfer rhythm of the transfer tools. This not only greatly improves the system's automation level, reduces manual intervention, lowers labor costs and the risk of operational errors, but also ensures that the entire ash removal process is efficient, stable, and orderly, achieving seamless connection between each link, fully leveraging the system's optimal performance, and effectively improving the efficiency and quality of rotary drum ash treatment.

[0028] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0029] This invention automates the operation of rotary drum ash handling, greatly reducing manual intervention. In hot weather, workers no longer need to perform dangerous and high-intensity labor such as ash removal and loading in high-temperature environments for extended periods, effectively avoiding the risk of heatstroke and inhalation of harmful substances, and ensuring the health of workers and production safety.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0036] Example 1

[0037] In the production of yellow phosphorus, the treatment of drum ash has always been a critical link affecting production efficiency, safety, and environmental protection. Traditional treatment methods have many drawbacks, such as high labor intensity for workers, long production cycles, and high environmental pollution risks. To solve these problems, this embodiment 1 provides a drum ash removal system, such as... Figure 1 As shown, the device includes a trough 6 and a transport assembly. The trough 6 has a chamber for receiving high-temperature ash slag discharged from the drum 1. The transport assembly includes an extraction device. The suction end of the extraction device is located in the chamber, and the outlet end of the extraction device is located above the trough 6. The extraction device, driven by a drive device, lifts the ash slag from the trough 6 to an ash hopper located at a higher position.

[0038] Please refer to Figure 1As shown, the trough 6 is made of high-temperature and corrosion-resistant steel, and its internal chamber is rectangular in shape. This chamber is located below the discharge port 2 of the drum 1. When the drum 1 discharges slag, the slag is rotated out of the discharge port 2 at the lowest point by centrifugal force and enters the chamber for cooling. Here, in order to avoid the high-temperature slag that has just been discharged directly affecting the suction end of the extraction device, and to ensure that the extraction device works in a relatively suitable temperature environment and reduce the risk of equipment damage due to high temperature, the chamber of the trough 6 also includes a vertical insert plate 5. The vertical insert plate 5 is made of high-temperature resistant material and divides the chamber into two independent chambers. The vertical insert plate 5 can be opened and closed manually. The chamber where the suction end is located is located in one of the chambers, and the other chamber is used to receive the high-temperature slag. After the high-temperature slag cools in the chamber (when the temperature drops, the slag becomes stable and agglomerated), the vertical insert plate 5 is opened, and the slag rolls into the chamber with the suction end of the extraction device under the action of gravity.

[0039] The extraction device includes an auger 4, which lifts the ash slag rolling in from the trough 6 to the ash silo located at a higher level. A transfer tool, which is a trolley or belt conveyor, is also installed at the auger outlet 3 to transfer the ash slag output from the auger outlet 3 to the ash silo. It can work continuously without the need for manual turnover and is not affected by the drum 1. This changes the past situation where the drum 1 could only be restarted after manual operation. Now the drum 1 can work continuously, which greatly improves production efficiency and reduces labor costs.

[0040] Example 2

[0041] To further improve the automation level of this utility model and reduce manual intervention, Embodiment 2 provides another rotary drum ash removal system based on the technical solution of Embodiment 1, such as... Figure 2 As shown, the vertical insert plate 5 can be opened and closed by a control device. The control device is electrically connected to the drum 1, the vertical insert plate 5, the auger 4, and the transfer tool. By precisely controlling the timing of ash discharge from the drum 1, the opening and closing state of the vertical insert plate 5, the operating speed and start / stop of the auger 4, and the material transfer rhythm of the transfer tool, the automation level of the system is greatly improved.

[0042] Meanwhile, a flow guiding device is connected between the discharge port 2 of the aforementioned drum 1 and the ground trough 6. This flow guiding device is a flow guiding plate 7 or a flow guiding channel inclined at 45 degrees. It is made of silicon carbide ceramic material with a smooth surface and is installed between the discharge port 2 of the drum and the ground trough 6. It is fixed by a stainless steel bracket to ensure that the high-temperature ash slag discharged from the drum can be accurately guided into the head chamber of the ground trough 6.

[0043] Work process

[0044] After the mud-phosphorus burning process is completed in drum 1, ash discharge begins. The high-temperature drum ash is discharged from outlet 2 under centrifugal force and falls into the chamber at the head of the trough 6 to receive high-temperature ash slag. At this time, the vertical insert plate 5 is in the closed state to protect the auger 4 and subsequent components from the high temperature.

[0045] After the ash discharge from drum 1 is completed, the next batch of mud-phosphorus burning can begin immediately, without waiting for the ash to cool. After the ash in the trough 6 has cooled naturally for a period of time, the control device sends a command to open the vertical insert plate 5.

[0046] Next, the control device starts the auger drive motor, and auger 4 begins to rotate, gradually pushing the cooled ash to the inlet of the belt conveyor. At the same time, the belt conveyor starts and transports the ash to the high-level ash silo at an appropriate speed. Then, an electric forklift transfers the ash from the rotating drum to the warehouse, which reduces manpower consumption without affecting production efficiency.

[0047] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
