Description

Technical Field

[0001] This utility model belongs to the field of aluminum electrolysis production technology, and specifically relates to a tool for cleaning aluminum suction tubes. Background Technology

[0002] Vacuum ladle is an important piece of equipment in the production process of molten aluminum electrolysis. It is the key to connecting the aluminum electrolysis workshop and the casting workshop. Compared with other metallurgical special machinery and equipment, its manufacturing precision is not high and its structure is not very complex. However, due to its high frequency of use and long-term contact with high-temperature molten aluminum, its inner wall inevitably adheres and forms a slag layer. When it reaches a certain thickness or weight, it will affect the normal use of the vacuum ladle and requires cleaning of the internal slag.

[0003] During operation, electrolytes and various other impurities and slags easily accumulate and adhere to the bottom, walls, and aluminum suction tubes of vacuum ladles, affecting their volume and hindering aluminum suction. Timely cleaning is essential. Currently, aluminum companies mostly use a combination of mechanical high-temperature cleaning and manual cooling cleaning for vacuum ladle cleaning. First, after the molten aluminum has been poured out, the high-temperature ladle requiring cleaning is quickly cleaned using specialized equipment to remove most of the slag. At this point, the internal temperature of the vacuum ladle is around 380℃~500℃, and the internal slag has relatively low hardness, making it easy to clean. After mechanical cleaning, it is allowed to cool naturally, and manual cleaning is performed on areas that the mechanical equipment cannot reach, especially the aluminum pouring port and aluminum suction tubes. However, cleaning the aluminum suction tubes is often done using pneumatic picks due to the confined space, which is inefficient. The internal slag often becomes very difficult to clean due to high-temperature sintering and molten aluminum penetration, resulting in high labor intensity for maintenance workers, potential health risks, and other safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a tool for cleaning aluminum suction tubes, so as to effectively improve the efficiency of aluminum suction tube cleaning and reduce safety risks during the operation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A tool for cleaning aluminum suction tubes includes a transmission rod and a sleeve fitted over the transmission rod. A bearing is provided between the transmission rod and the sleeve. A blower interface and a rotating head are respectively provided at both ends of the transmission rod. A square hole is provided in the blower interface for connecting the blower. A slag-cleaning knife is provided at the end of the rotating head away from the transmission rod. The slag-cleaning knife has a cylindrical structure and includes a plurality of uniformly arranged blades. A wedge-shaped groove is provided on the side of the blades facing each other. A cutting edge is provided at the end and both sides of the blades.

[0007] To further realize this utility model, the axes of the transmission rod, sleeve, air gun interface, rotating head and slag removal knife are located on the same straight line.

[0008] To further realize this utility model, the diameter of the slag-cleaning knife is larger than the diameter of the sleeve but smaller than the inner diameter of the aluminum suction tube. This allows the slag-cleaning knife sufficient room to move inside the aluminum suction tube, ensuring smooth slag removal.

[0009] To further realize this utility model, the end of the square hole away from the transmission rod is open.

[0010] To further realize this utility model, the bearing includes two bearings, which are respectively disposed on the inner walls at both ends of the sleeve.

[0011] To further realize this utility model, the rotating head includes a connecting end, a first-level step, and a second-level step connected in sequence. The connecting end is connected to the transmission rod. The diameters of the connecting end, the first-level step, and the second-level step increase progressively. The diameter of the connecting end is not less than that of the transmission rod. The diameter of the first-level step is less than that of the sleeve. The diameter of the second-level step is greater than that of the sleeve. The bottom end of the cutter head is fixedly connected to the surface of the second-level step.

[0012] To further realize this utility model, the radial length of the blade is 5cm-8cm.

[0013] To further realize this utility model, the outer diameter of the sleeve is 8cm-10cm and the length is greater than 45cm. The inner diameter of the aluminum suction tube is 12cm-13cm, and the segment length of the aluminum suction tube is generally 60cm-90cm. The outer diameter and length of the sleeve are set to ensure that it can be inserted from both ends to thoroughly clean the inside of the aluminum suction tube.

[0014] To further realize this utility model, the transmission rod is made of high-strength steel bars with a diameter greater than 2cm, and the length of the transmission rod is the same as the length of the sleeve. Because the slag inside the aluminum suction tube has a complex composition, including electrolytes, alumina, and filter residue, and is quite hard, the device of this utility model experiences significant stress during operation. Therefore, it is necessary to limit the material and diameter of the transmission rod to ensure its strength, and to limit the length of the transmission rod and its alignment with the axis of the sleeve to ensure that the transmission rod rotates around the axis during operation.

[0015] To further realize this utility model, the air gun interface is made of high-strength steel.

[0016] The advantages of this utility model compared to the prior art are as follows:

[0017] The vacuum lifting ladle used in modern large-scale aluminum electrolysis cell production is generally over 10 tons, and the inner diameter of the aluminum suction tube is generally 12cm-13cm. When this tool is working, it needs to be inserted into the aluminum suction tube. The inner walls of both ends of the sleeve of this utility model are equipped with bearings. The outer ring of the bearing is fixedly connected to the sleeve, and the inner ring is fixedly connected to the transmission rod. The sleeve and bearings are mainly for safety protection and convenient operation. When this tool is working, the outer sleeve does not move, and the transmission rod rotates rapidly.

[0018] This utility model device has a simple structure and low manufacturing cost. Ordinary technicians in the field of aluminum electrolysis anode group production technology can manufacture it themselves according to the technical solution. The method of using this utility model is simple, and technicians in this industry can understand and apply it to production according to the technical solution. Through the implementation of this utility model, the efficiency of cleaning aluminum tubes in aluminum electrolysis vacuum lifting ladle can be effectively improved, and the safety risks in the operation process can be reduced.

[0023] like Figure 1-2 As shown, an aluminum suction tube cleaning tool includes a transmission rod 1 and a sleeve 2 sleeved outside the transmission rod 1. Bearings 3 are provided between the transmission rod 1 and the sleeve 2. Two bearings 3 are respectively located on the inner walls of both ends of the sleeve 2. A blower interface 4 and a rotating head 5 are respectively provided at both ends of the transmission rod 1. A square hole 6 is provided inside the blower interface 4. The rotating head 5 includes a connecting end 5-1, a first-level step 5-2, and a second-level step 5-3 connected in sequence. The connecting end 5-1 is connected to the transmission rod 1. The diameters of the connecting end 5-1, the first-level step 5-2, and the second-level step 5-3 increase progressively. The diameter of the connecting end 5-1 is not less than that of the transmission rod 1, and the diameter of the first-level step 5-2 is less than that of the sleeve 2. The diameter of the sleeve 2 and the diameter of the secondary step 5-3 are larger than the diameter of the sleeve 2. The square hole 6 is open at the end away from the transmission rod 1. The end of the rotating head 5 away from the transmission rod 1 is equipped with a slag cleaning knife 7. The exterior of the slag cleaning knife 7 is a cylindrical structure. The axes of the transmission rod 1, sleeve 2, air gun interface 4, rotating head 5 and slag cleaning knife 7 are on the same straight line. The diameter of the slag cleaning knife 7 is larger than the diameter of the sleeve 2 and smaller than the inner diameter of the aluminum suction tube. The slag cleaning knife 7 includes several uniformly arranged cutter heads 7-1. A wedge-shaped groove 7-2 is provided on the opposite side of the cutter heads 7-1. The end and both sides of the cutter heads 7-1 are respectively provided with cutting edges 7-3. The bottom end of the cutter head 7-1 is fixedly connected to the surface of the secondary step 5-3.

[0024] During the operation, first insert the prepared slag-removing knife 7 and rotating head 5 into the aluminum suction pipe that needs to be cleaned. Connect the air gun to the tool through the air gun interface 4. The operator holds the sleeve 2 and starts the air gun to make the transmission rod 1 drive the rotating head 5 and slag-removing knife 7 to rotate. At the same time, shake the tool left and right to make the slag-removing knife 7 contact the inner wall of the aluminum suction pipe and gradually penetrate into the aluminum suction pipe to clean the slag inside the aluminum suction pipe. After the tool is fully inserted into the aluminum suction pipe and completes the cleaning of this part of the slag, take out the tool and start cleaning from the other end of the aluminum suction pipe. Repeat the above actions to complete the overall cleaning of the aluminum suction pipe.

[0025] Example:

[0026] A certain aluminum electrolysis production line uses a 500kA large prebaked cell and is equipped with a 14-ton aluminum vacuum lifting ladle. The aluminum suction pipe is divided into 4 sections: one section with a bend length of 252mm, and three sections with straight pipe lengths of 610mm, 750mm, and 900mm respectively, all with an inner diameter of 130mm.
