[0001] The utility model relates to the technical field of aluminum processing, in particular to a device for cleaning impurities on the surface of an aluminum ingot. Background Art

[0002] In the aluminum processing industry, especially in the aluminum extrusion production process, the preheating treatment of aluminum ingots is a crucial step, which is directly related to the quality and efficiency of subsequent extrusion molding. In the traditional process, before the aluminum ingot enters the induction furnace for heating, its surface is often attached with aluminum chips, dust or other impurities. If these residues are not effectively removed, they may not only pollute the furnace environment and cause uneven heating, but also react with the substrate under high temperature, affecting the mechanical properties and surface quality of the final product. Therefore, efficient and reliable ingot surface cleaning measures are one of the key links to ensure product quality.

[0003] In the existing solutions, the method of removing aluminum chips from aluminum ingots is mostly to use a handheld chip blower. However, this manual operation has significant defects. First, the operation of the handheld chip blower requires direct human participation, which not only increases the labor intensity of the workers, but also reduces the automation level of the production line.

[0004] Therefore, how to provide an aluminum ingot surface impurity cleaning device to automatically and efficiently remove aluminum chips and impurities on the surface of the aluminum ingot before it enters the induction furnace is a technical problem that technicians in this field currently need to solve. Utility Model Content

[0005] The utility model aims to provide an aluminum ingot surface impurity cleaning device to solve the technical problem that the existing handheld chip blower has high labor intensity for workers.

[0007] A mounting seat, wherein a conveying roller and a driving member are provided on the mounting seat, wherein the conveying roller is arranged between the inlet of the induction furnace and the output end of the driving member, and the driving member is used to push the aluminum ingot located on the conveying roller into the induction furnace;

[0008] A circular blow pipe, wherein the circular blow pipe is sleeved on the conveying roller, air outlet holes facing the conveying roller are arranged on both sides of the circular blow pipe, an air inlet end of the circular blow pipe is connected to an air pipeline, and a ball valve is arranged on the air pipeline.

[0009] Preferably, the driving member is a hydraulic cylinder, and the center line of the inlet of the induction furnace, the center line of the conveying roller and the center line of the hydraulic cylinder are located on the same axis.

[0014] Compared with the above-mentioned background technology, the device for cleaning impurities on the surface of aluminum ingots provided by the utility model places the aluminum ingot on a conveyor roller, starts a driving part, and pushes the aluminum ingot in the direction of the induction furnace. During the movement of the aluminum ingot, the ball valve is opened at the same time to allow gas to enter the annular blowpipe through the gas pipeline. The gas is ejected from the air outlet holes on both sides of the annular blowpipe to clean the surface of the aluminum ingot in all directions.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] See also Figure 1 The present application provides an aluminum ingot surface impurity cleaning device, comprising a mounting base 1, on which a conveyor roller and a driving member 2 are provided, the conveyor roller is located between the entrance of the induction furnace 3 and the output end of the driving member 2, and the driving member 2 is used to push the aluminum ingot 4 located on the conveyor roller into the induction furnace 3; an annular blow pipe 5, the annular blow pipe 5 is sleeved on the conveyor roller, and both sides of the annular blow pipe 5 are provided with air outlet holes 51 facing the conveyor roller, the air inlet end of the annular blow pipe 5 is connected to the air supply pipeline 6, and the air supply pipeline 6 is provided with a ball valve 7; a controller, and the controller establishes a signal connection with the driving member 2.

[0023] That is to say, the conveyor roller is located on the mounting seat 1, which is used to carry the aluminum ingot 4 and ensure that it moves smoothly to the induction furnace 3. The driving member 2 is located at one end of the conveyor roller, and its movement is controlled by the controller to push the aluminum ingot 4 into the induction furnace 3. The annular blowpipe 5 is sleeved on the conveyor roller, which can fit the moving path of the aluminum ingot 4, and the annular blowpipe 5 does not affect the passage of the aluminum ingot 4. Both sides of the annular blowpipe 5 are provided with air outlets 51 facing the conveyor roller, and these air outlets can evenly blow out gas to clean the surface of the aluminum ingot 4 in all directions. The air inlet end of the annular blowpipe 5 is connected to the gas supply pipeline 6 to ensure that the gas can smoothly enter the annular blowpipe 5. The gas supply pipeline 6 is used to provide the annular blowpipe 5 with the gas required for cleaning. The ball valve 7 is installed on the gas supply pipeline 6 to control the opening or closing of the ball valve 7 to adjust the gas flow and switch state to ensure the safety and effectiveness of the cleaning process.

[0024] The working principle is as follows: the aluminum ingot 4 is placed on the conveyor roller, and the driving member 2 is started, and the driving member 2 pushes the aluminum ingot 4 to the direction of the induction furnace 3. During the movement of the aluminum ingot 4, the ball valve 7 is opened at the same time, so that the gas enters the annular blowpipe 5 through the gas pipeline 6. The gas is ejected from the gas outlets 51 on both sides of the annular blowpipe 5 to clean the surface of the aluminum ingot 4 in all directions. When the aluminum ingot 4 moves to the entrance of the induction furnace 3, the ball valve 7 is closed and the driving member 2 is stopped. At this time, the driving member 2 returns to its original position, thereby completing a cleaning process.

[0025] In summary, the aluminum ingot surface impurity cleaning device provided by the present application realizes the surface impurity cleaning of the aluminum ingot before entering the induction furnace. The device has a simple structure, convenient operation, good cleaning effect, reduces the labor intensity of workers, can significantly improve the heating effect of the aluminum ingot and the stability of material properties, and has broad application prospects in the aluminum processing industry.

[0026] Based on the above embodiment, the driving member 2 is a hydraulic cylinder, and the center line of the entrance of the induction furnace 3, the center line of the conveying roller and the center line of the hydraulic cylinder are located on the same axis.

[0027] In other words, the driving member 2 uses a hydraulic cylinder. The hydraulic cylinder has a strong thrust and precise control performance, which ensures the stability and accuracy of the aluminum ingot 4 during the transportation process. In order to ensure that the aluminum ingot 4 can accurately enter the induction furnace 3 for subsequent processing, the center line of the entrance of the induction furnace 3, the center line of the conveying roller and the center line of the hydraulic cylinder are designed on the same axis. The advantage is that when the hydraulic cylinder is working, the telescopic movement of its piston rod can directly and accurately push the aluminum ingot along the conveying roller to the entrance of the induction furnace 3. Since the center lines of the three completely coincide, the aluminum ingot 4 will not deviate or shake during the pushing process, thereby ensuring that the aluminum ingot can accurately enter the induction furnace 3 and avoiding unnecessary losses and safety hazards caused by position deviation.

[0028] On the basis of the above embodiment, a solenoid valve 8 is provided on the gas pipeline 6, and the aluminum ingot surface impurity cleaning device also includes a controller, the solenoid valve 8 establishes a signal connection with the controller, and the hydraulic cylinder establishes a signal connection with the controller.

[0029] That is to say, the controller has established signal connections with the solenoid valve 8 and the hydraulic cylinder, ensuring the precise control of the entire cleaning process. First, the gas pipeline 6 is responsible for providing cleaning gas to the annular blowpipe 5. In order to ensure that the gas can be accurately supplied as needed, a solenoid valve 8 is set on the gas pipeline 6. By controlling the opening and closing of the solenoid valve 8, we can accurately adjust the gas flow and purge time according to the position and speed of the aluminum ingot on the conveyor roller, so as to achieve the best cleaning effect.

[0030] On the basis of the above embodiment, a proximity switch is provided on the annular blowpipe 5, and a signal connection is established between the proximity switch and the controller.

[0031] That is to say, the annular blowpipe 5 is sleeved on the conveyor roller, and when the aluminum ingot 4 passes by, the gas in the annular blowpipe 5 can evenly and effectively purge the surface of the aluminum ingot 4 to remove impurities. In order to ensure that the annular blowpipe 5 starts working when the aluminum ingot 4 reaches the predetermined position, a proximity switch is installed on the annular blowpipe 5. The proximity switch is installed at a suitable position of the annular blowpipe 5 so as to send a signal when the aluminum ingot 4 approaches. This signal is then transmitted to the controller, and the controller, according to the preset program and algorithm, will immediately start the solenoid valve 8 after receiving the signal from the proximity switch, open the gas pipeline 6, allow the gas to enter the annular blowpipe 5, and start to purge the surface of the aluminum ingot.

[0032] In addition, the sensitivity of the proximity switch is adjustable, which means that we can accurately set the detection distance and response time of the proximity switch according to the size, speed and cleaning requirements of the aluminum ingot. In this way, we can ensure that when the aluminum ingot 4 reaches the predetermined position, the annular blowpipe 5 can start working immediately, thereby achieving accurate and effective cleaning. The controller can automatically adjust the opening time and gas flow of the solenoid valve 8 according to the signal of the proximity switch to meet the cleaning requirements of different aluminum ingots. This intelligent control method greatly improves the cleaning efficiency and product quality, while also reducing the difficulty of operation and labor costs.

[0033] The present application also provides another embodiment, in which a travel switch 9 is provided on the mounting seat 1 , and a signal connection is established between the travel switch 9 and the solenoid valve 8 .

[0034] That is to say, when the hydraulic cylinder is working, the piston rod pusher pushes the aluminum ingot 4 steadily into the induction furnace 3. During the pushing process, the piston rod pusher gradually approaches and finally hits the pre-installed travel switch 9, which is directly used in the prior art. The travel switch 9 is designed to open when hit, and its internal contacts will change, thereby sending a start signal to the controller. After receiving the start signal of the travel switch 9, the controller will immediately issue an instruction to the solenoid valve 8. After receiving the instruction, the solenoid valve 8 will open immediately, and the gas in the gas pipeline 6 will enter the annular blowpipe 5 to start blowing the surface of the aluminum ingot 4. Then, the aluminum chips and impurities on the surface of the aluminum ingot 4 will be blown away, ensuring that its surface is clean and free of impurities, providing good conditions for subsequent smelting or processing. When the aluminum ingot 4 is pushed into the specified position of the induction furnace 3, the piston rod of the hydraulic cylinder begins to retract, preparing for the next pushing operation. During the retraction process, the piston rod pusher will hit the travel switch again. At this time, its internal contacts will change, thereby sending a closing signal to the controller. After receiving the closing signal, the control system will immediately issue a closing command to the solenoid valve 8. After receiving the command, the solenoid valve 8 will quickly close its internal channel and cut off the supply of the purge medium.

[0035] The controller is a programmable logic controller or a single chip microcomputer.

It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
