Description

Technical Field

[0001] This invention relates to the field of matte furnace technology, specifically to a matte furnace charge loosening machine and its loosening method. Background Technology

[0002] The matte smelting furnace is an important piece of equipment in the copper smelting process used to convert copper sulfide concentrate into matte (a copper-sulfur compound). Its main function is to combine copper and sulfur elements in the copper sulfide concentrate through a high-temperature smelting process to form matte, providing raw materials for subsequent refining. In copper ore metallurgy, ore needs to be fed into the furnace via a feeding mechanism. During the feeding process, the varying sizes of the copper ore often cause it to get stuck in the conveying channel, resulting in feeding obstruction. Therefore, it is necessary to frequently loosen the conveying channel.

[0003] In the loosening of the charge in a copper matte furnace, a vibratory device is directly installed inside the furnace body pipes for vibration loosening. However, this method cannot be installed separately and in a fixed spatial position, which is not only limited to a fixed spatial position, but also easily interferes with the installation and use, and is inconvenient to disassemble and maintain, thus affecting the performance. Therefore, a new loosening structure and method need to be proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a furnace charge loosening machine and method for matte furnaces, thereby solving the problem of charge blockage that easily occurs in existing matte furnaces.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a copper matte furnace charge loosening machine and its loosening method, comprising a hopper, a connecting pipe fixedly connected to the lower surface of the hopper, a feeding pipe fixedly connected to the side of the hopper, an mounting plate fixedly connected to the upper end of the hopper, an mounting cylinder fixedly connected to the upper surface of the mounting plate, a sealing plate slidably mounted inside the mounting cylinder, a sealing ring fixedly sleeved on the outer circular surface of the sealing plate, the sealing ring slidably connected to the inner wall surface of the mounting cylinder, a motor fixedly mounted on the upper surface of the sealing plate, a hollow rotating shaft assembled and mounted on the shaft end of the motor, a through hole provided at the upper end of the outer surface of the hollow rotating shaft, and the hollow rotating shaft rotatably mounted on the lower surface of the sealing plate; The lower end of the hollow rotating shaft is threaded with a combined cylinder, and the lower end of the combined cylinder is fixedly connected to a connecting box. The connecting box is slidably installed in the middle of the inside of the hopper. A loosening tube is fixedly installed on the lower surface of the connecting box. The surface of the loosening tube is provided with air jet holes. The loosening tube is fixedly arranged on one side of the lower surface of the connecting box, and the loosening tube is located on one side of the upper end of the connecting tube. The loosening method of this loosening machine includes the following steps: S1. Fix the connecting pipe at the lower end of the hopper to the upper end of the matte furnace, align the connecting pipe on the side with the feeding pipe, and transfer the furnace material through the hopper to the matte furnace for processing. S2. After the furnace charge is blocked at the position inside the connecting pipe, the control sealing plate moves downward, which moves the hollow rotating shaft downward, and moves the combined cylinder and connecting box synchronously. S3. The loosening pipe installed below the connecting box is inserted into the inside of the connecting pipe to vibrate and loosen the accumulated furnace material, forming holes and then dispersing it. S4. The synchronous control motor drives the hollow rotating shaft to rotate, and the connecting box drives the loosening tube to rotate, adjusting the eccentrically set loosening tube to different positions inside the connecting tube, and loosening at multiple positions. S5. Compressed air is introduced into the mounting cylinder, enters the hollow rotating shaft through the through hole, and enters the connecting box through the combined cylinder. S6. Compressed air enters the loosening pipe and is pressurized and ejected through the jet holes on the surface. During the up-and-down vibration loosening process, the jet airflow sweeps the loosening area, accelerates the dispersion and falling of the furnace material, and allows it to fall down from the inside of the connecting pipe and enter the matte furnace in time, thus completing the loosening process.

[0006] Preferably, there are three loose tubes, which grow from the center to the outer side and are arranged in a stepped manner. By arranging the loose tubes of different sizes in a stepped manner, they can be positioned eccentrically, reducing interference with the connecting tubes and reducing the resistance of vibration, making it convenient for combined use.

[0007] Preferably, the upper surface of the connecting box is provided with a conical guide surface, and the end of the conical guide surface is connected to the lower end of the combined cylinder.

[0008] Preferably, one side of the connecting box is provided with a flat surface, and the position located at the lower end of the combined cylinder is provided with a conical guide surface and a flat surface. The position can be set at half, which reduces interference and facilitates the sliding of the backflow furnace charge, thus having high adaptability.

[0009] Preferably, the upper surface of the mounting cylinder is provided with a clearance hole, which is fitted onto the outer surface of the motor.

[0010] Preferably, a mounting hole is provided on one side of the sealing plate, and a push rod is fixedly installed inside the mounting hole.

[0011] Preferably, the upper end of the push rod is fixedly connected to a telescopic rod, which is fixedly installed on the upper surface of the mounting cylinder and located on one side of the clearance hole. The push rod and the telescopic rod are connected through the mounting hole on the sealing plate, which allows for separate installation and positioning. This facilitates positioning on the mounting cylinder for telescopic adjustment, and enables loosening and lifting control. It is efficient, stable, and convenient for installation and use.

[0012] Preferably, an air pump is fixedly installed on one side surface of the mounting cylinder, and an air pump pipe is fixedly connected to one end of the air pump.

[0013] Preferably, the outlet of the air pump is located inside the mounting cylinder. By installing the air pump and air extraction pipe on the side of the mounting cylinder, air can be compressed and loosened into the interior, which is beneficial for impacting the loosened area, improving the dispersion speed, ensuring the loosening effect, and facilitating installation and use.

[0014] Compared with the prior art, the present invention provides a furnace charge loosening machine and a loosening method for matte furnaces, which has the following beneficial effects: Through its design, the loosening machine uses a hopper cover plate and mounting cylinder, combined with an internally connected hollow rotating shaft to position and connect the housing and loosening pipe. This facilitates separate installation and positioning on the matte furnace, avoiding space limitations. Furthermore, it allows for lifting and rotation adjustment for vibration loosening, reducing internal positional interference, exhibiting high adaptability, ensuring feeding and loosening efficiency, and benefiting production use.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This invention provides a technical solution: a furnace charge loosening machine and its loosening method for matte furnaces. Please refer to [link to relevant documentation]. Figure 1 , Figure 2 , Figure 4 and Figure 6 The system includes a hopper 1, a connecting pipe 11 fixedly connected to the lower surface of the hopper 1, a feed pipe 12 fixedly connected to the side of the hopper 1, an mounting plate 13 fixedly connected to the upper end of the hopper 1, an mounting cylinder 14 fixedly connected to the upper surface of the mounting plate 13, a sealing plate 15 slidably installed inside the mounting cylinder 14, and a sealing ring 16 fixedly sleeved on the outer circular surface of the sealing plate 15. The sealing plate 15 and the sealing ring 15 are connected to ensure the sealing stability during vertical adjustment, which can both vibrate and convey the material vertically and prevent compressed air leakage, thus improving the safety of use. The sealing ring 16 is slidably connected to the inner wall surface of the mounting cylinder 14. A motor 17 is fixedly installed on the upper surface of the sealing plate 15, and a hollow rotating shaft 18 is assembled and installed on the shaft end of the motor 17. The upper end of the outer surface of the hollow rotating shaft 18 is provided with a through hole 19. The hollow rotating shaft 18 is rotatably installed on the lower surface of the sealing plate 15. By connecting the hollow rotating shaft 18, the position can be adjusted by rotation, and compressed gas can be guided to facilitate the impact of the furnace material to assist in loosening. It is highly efficient, stable, and adaptable. The lower end of the hollow rotating shaft 18 is threaded with a combined cylinder 2, and the lower end of the combined cylinder 2 is fixedly connected to a connecting box 21. The connecting box 21 is slidably installed in the middle of the inside of the hopper 1. A loosening tube 22 is fixedly installed on the lower surface of the connecting box 21. The surface of the loosening tube 22 is provided with air jet holes 23. The loosening tubes 22 are fixedly arranged on one side of the lower surface of the connecting box 21. The loosening tubes 22 are spaced apart on one side of the upper end of the connecting pipe 11. They are inserted into the blocked furnace material in stages, which can reduce resistance and improve the stability of use. They can be inserted and vibrated from top to bottom, and can also be rotated to stir, which is conducive to the dispersion and falling of the furnace material. They are easy to loosen and adjust, and have high adaptability. The loosening method of this loosening machine includes the following steps: S1. Fix the connecting pipe 11 at the lower end of the hopper 1 to the upper end of the matte furnace, and align the connecting pipe 12 on the side with the feeding pipe. After passing through the hopper, the furnace material is loosened and fed into the matte furnace for processing. S2. After the furnace charge is blocked at the position inside the connecting pipe 11, the control sealing plate 15 moves downward, which moves the hollow rotating shaft 18 downward, and moves the combined cylinder 2 and the connecting box 21 synchronously. S3. The loosening pipe 22 installed below the connecting box 21 is inserted into the inside of the connecting pipe 11 to vibrate and loosen the accumulated furnace material, forming holes and then dispersing it. S4. Synchronous control motor 17 drives hollow rotating shaft 18 to rotate, and combined with connecting box 21 drives loosening tube 22 to rotate, adjusting the eccentrically set loosening tube 22 to different positions inside connecting tube 11, and loosening at multiple positions. S5. Compressed air is introduced into the mounting cylinder 14, passes through the through hole 19 into the hollow rotating shaft 18, and enters the connecting box 21 through the combined cylinder 2. S6. Compressed air enters the loosening pipe 22 and is pressurized and ejected through the jet holes 23 on the surface. During the up-and-down vibration loosening process, the jet air blows through the loosening position, accelerates the dispersion and falling of the furnace material, and promptly falls down from the inside of the connecting pipe 11 into the matte furnace, thus completing the loosening process.

[0019] Please see Figure 2 , Figure 5 and Figure 6 There are three loose tubes 22, which grow from the center to the outer side and are arranged in a stepped manner. By arranging different loose tubes in a stepped manner, they can be eccentrically positioned, reducing interference with the connecting tubes and reducing the resistance of vibration, making it convenient for combined use.

[0020] Please see Figure 5 and Figure 6 The upper surface of the connecting box 21 is provided with a conical guide surface 24. The end of the conical guide surface 24 is connected to the lower end of the combined cylinder 2. A flat surface 25 is provided on one side of the connecting box 21. The conical guide surface and the flat surface are located on the lower side of the combined cylinder 2. By setting the connecting box with a conical guide surface and a flat surface, half of the position can be set, reducing interference and facilitating the backflow of furnace charge. It has high adaptability. By setting the flat surface 25, only half of the connecting box 21 can be formed. This can reduce the coverage area of ​​the connecting tube 11, avoid interference with material discharge, and facilitate installation and use. After rotation and adjustment, it can be aligned with different positions of the connecting tube 11 to ensure the fullness of the loose material and avoid omission.

[0021] Please see Figure 2 and Figure 3The upper surface of the mounting cylinder 14 is provided with a clearance hole 26, which is fitted onto the outer surface of the motor 17. One side of the sealing plate 15 is provided with a mounting hole 3, inside which a push rod 31 is fixedly installed. The upper end of the push rod 31 is fixedly connected to a telescopic rod 32, which is fixedly installed on the upper surface of the mounting cylinder 14 and located to one side of the clearance hole 26. The push rod and telescopic rod are connected through the mounting hole on the sealing plate, allowing for separate installation and positioning. This facilitates positioning on the mounting cylinder for telescopic adjustment and facilitates lifting control for loosening. It is highly efficient, stable, and easy to install and use. The push rod 31 and telescopic rod 32 are connected through the mounting hole 3, and the height can be adjusted by telescopic control from the top, so as to vibrate and convey the blocked furnace material. It is easy to control and use. The telescopic rod 32 pushes the sealing plate 15 up and down, which can ensure the sealing stability, avoid the leakage of compressed air inside the mounting cylinder 14, and improve the stability of use. Furthermore, the avoidance hole 26 set at the upper end of the mounting cylinder 14 can avoid the motor 17 for lifting and adjusting, avoid mutual interference, and facilitate installation and use.

[0022] Please see Figure 1 and Figure 2 An air pump 33 is fixedly installed on one side surface of the mounting cylinder 14. One end of the air pump 33 is fixedly connected to an air extraction pipe 34. The outlet of the air pump 33 is located inside the mounting cylinder 14. By installing the air pump and air extraction pipe on the side of the mounting cylinder, air can be compressed and loosened into the interior, which is conducive to impacting the loosened area, improving the dispersion speed, ensuring the loosening effect, and facilitating installation and use. By connecting the air pump 33 to the air extraction pipe 34, external air can be extracted, pressurized, and delivered into the interior of the mounting cylinder 14. In this way, compressed air can enter the hollow rotating shaft 14 through the through hole 19, which can ensure the airflow impact effect without interfering with the rotation adjustment of the hollow rotating shaft 18, making it convenient to control and use, and highly adaptable.
