Description

Technical Field

[0001] This invention belongs to the technical field of wire drawing equipment, and in particular relates to an online cleaning device for a straight-line wire drawing machine. Background Technology

[0002] Straight-line wire drawing machines are used in the metal products industry for drawing steel wires. They employ advanced transmission and automated control systems to achieve high-speed continuous wire drawing. Compared to traditional water tank wire drawing machines, they have higher production efficiency and lower energy consumption, meeting the needs of large-scale production. However, lubricating powder residue is easily left on the surface of the steel wire during processing, requiring a cleaning device to optimize subsequent processes. For example, patent CN219703038U discloses an online cleaning device for wire drawing machines.

[0003] Currently, the wire drawing process using a straight-line wire drawing machine requires the use of lubricating powder to ensure the quality of the wire drawing. However, the surface of the wire is relatively rough after drawing, and a large amount of lubricating powder will remain on the rough surface of the wire. This makes it easy for the lubricating powder to clog the heat exchanger of the heat treatment furnace in the subsequent heat treatment process, and affect the heat exchange effect. This not only affects the energy-saving and environmental protection effect of wire processing, but also affects the continuity and efficiency of wire processing.

[0004] In addition, before the steel wire is drawn by the straight-line wire drawing machine, it needs to be surface treated with metal wire drawing saponification liquid. The core purpose of using metal wire drawing saponification liquid is to reduce the frictional resistance during the wire drawing process, protect the mold and improve the surface quality of the steel wire. However, waste saponification liquid is generated during this process. At present, enterprises generally collect the waste saponification liquid and outsource its treatment, which is not fully utilized and results in material waste.

[0005] To address this issue, we propose an online wire cleaning device for a straight-line wire drawing machine. Summary of the Invention

[0014] In the above-mentioned online cleaning device for a straight-line wire drawing machine, the cooling mechanism includes a cooling metal coil located in the cooling zone. The inlet end of the cooling metal coil passes through the upper surface of the processing box and is fixedly connected to the outer wall of the wire drawing die box at the drain hole.

The outer wall of the arc-shaped hollow block is provided with multiple liquid outlet holes.

[0015] In the above-mentioned online cleaning device for a straight-line wire drawing machine, the soap solution impurity separation mechanism includes a connecting bearing fixedly connected to the lower surface of a partition plate, a conical composite filter element bucket fixedly connected to the inner wall of the connecting bearing, an arc-shaped hollow block located inside the conical composite filter element bucket, a sealing bearing fixedly connected to the upper surface of the treatment box, a conduit fixedly connected to the inner wall of the sealing bearing, the inner wall of the top end of the conduit fixedly connected to the outer wall of the bottom end of the conical composite filter element bucket, an external toothed ring fixedly sleeved at the bottom end of the conduit, a U-shaped frame fixedly connected to the lower surface of the treatment box, a drive motor fixedly connected to the lower surface of the U-shaped frame, a gear meshing with the external toothed ring fixedly connected to the output end of the drive motor, a bent pipe fixedly connected to the outer wall of the partition plate located in the cooling zone, the air outlet end of the bent pipe located at the inner wall of the conical composite filter element bucket, and a drain hose fixedly connected to the bottom end of the treatment box.

[0016] In the above-mentioned online cleaning device for a straight-line wire drawing machine, a connecting frame is provided inside the conical composite filter element bucket.

[0017] In the above-mentioned online cleaning device for a straight-line wire drawing machine, four support legs are fixedly connected to the lower surface of the processing box, and a waste residue dryer is provided at the bottom end of the guide tube. The waste residue dryer is fixedly connected to two of the support legs.

[0018] Compared with existing technologies, the advantages of an online steel wire cleaning device for a straight-line wire drawing machine are:

[0019] 1. Through the set waste soap solution heating mechanism, vortex tube, wire drawing die box, and processing box, when the steel wire undergoes the final wire drawing process in the straight-in wire drawing machine, the steel wire passes through the wire drawing die box and the wire drawing mold. Then, the PLC controller injects compressed air into the vortex tube through the air compressor pump, and generates hot air which is injected into the heating zone and low-temperature air which is injected into the cooling zone. At the same time, the waste soap solution generated from the surface treatment process before wire drawing is input into the heating metal coil through the pipeline to raise the temperature. The heated waste soap solution and hot air are both injected into the wire drawing die box to achieve efficient cleaning of the surface of the steel wire inside the wire drawing die box. If the lubricating powder contains grease, the heated waste saponified liquid can soften or even liquefy the grease, reducing its adhesion to the steel wire surface. At the same time, it consumes the grease, significantly reducing the amount of residue on the steel wire surface that can clog the heat exchanger in the heat treatment furnace during the heat treatment process. This mechanism not only enables the device to efficiently clean the residue on the surface of steel wire produced by the straight-line wire drawing machine, but also reduces the risk of heat exchanger clogging in the next heat treatment process, improves the continuity and efficiency of steel wire processing, and can fully consume the waste saponified liquid generated in the previous surface treatment process, optimizing the chemical treatment process of adding acid to break emulsion and adding alkali to neutralize.

[0020] 2. Through the cooling mechanism and soap solution impurity separation mechanism, after the waste saponification liquid in the wire drawing die box has cleaned the residue on the surface of the steel wire, it will enter the cooling mechanism to cool down. At low temperature, the Brownian motion of colloidal particles weakens, the charge repulsion force decreases, and it is easier to coagulate or flocculate, accelerating solid-liquid separation. Then, the waste saponification liquid carrying large particles of waste residue is transported to the soap solution impurity separation mechanism and quickly separated by centrifugal force. The waste residue does not need to be left to stand and be sorted. The separated waste residue, with the assistance of low temperature air sprayed from the curved pipe, quickly enters the waste residue dryer along the inner wall of the conical composite filter bucket and the guide tube. The dried waste residue is discharged into the collection container through the waste residue dryer for external treatment, while the waste saponification liquid is thrown out by centrifugal force and accumulates at the bottom of the treatment tank. Finally, it is discharged into the collection container for external treatment through the drain hose. This mechanism enables the device to quickly separate solid impurities in the waste saponification liquid after cleaning, making the external treatment of waste saponification liquid and waste residue more convenient.

[0021] 3. Through the set temperature sensor and PLC controller, during the process of cleaning steel wire with waste saponification liquid in the wire drawing die box, the temperature sensor will detect the temperature of the waste saponification liquid in real time and convert the detected temperature value into an electrical signal and send it to the PLC controller. If the temperature of the waste saponification liquid does not reach the effective cleaning temperature preset by the PLC controller, the PLC controller will adjust the temperature of the hot air by controlling the pressure of the compressed air output by the air compressor pump. This adjusts the temperature of the waste saponification liquid entering the wire drawing die box to meet the requirements and ensures the cleaning effect of the steel wire. This mechanism gives the device an automatic adjustment function and ensures a reliable cleaning effect of the residue on the surface of the steel wire. Attached Figure Description

[0037] The inner wall of the wire drawing die box 1 is fixedly connected to a limiting plate 13 and a baffle 14.

The inner wall of the wire drawing die box 1 is fixedly connected to five sets of symmetrically distributed rolling bearings. The inner walls of each set of two rolling bearings are connected to a reversing roller 16. The five sets of reversing rollers 16 are distributed in a "W" shape inside the wire drawing die box 1. The outer walls of the wire drawing die box 1 and the baffle 14 are both provided with circular wire threading holes 17 at the same height. The drain hole 15 is located below the circular wire threading hole 17.

[0038] Temperature sensor 75 is electrically connected to the input terminal of PLC controller 76 via wires. Waste dryer 5, air compressor 79 and drive motor 97 are all electrically connected to the output terminal of PLC controller 76 via wires. The above-mentioned power supply equipment and electrical connections are all existing technologies and will not be described in detail here.

[0039] The operating principle of the present invention is described as follows: When the steel wire undergoes the final drawing process in the straight-line wire drawing machine, the steel wire passes through the drawing die box 1 and the drawing die 2, and the steel wire is also connected to five reversing rollers 16 in sequence to form a W-shaped path. Then, the PLC controller 76 controls the air compressor pump 79 to start. The compressed air from the air compressor pump 79 is injected into the vortex tube 10 through the connecting pipe 710. The compressed air (pressure is usually 0.3-1.0MPa) is accelerated by the guide vanes and forms a high-speed rotating vortex. Due to the vortex effect, the airflow is separated into an outer high-speed rotating hot airflow and an inner low-speed rotating cold airflow. The hot airflow enters the heating zone 11 through the hot end outlet of the vortex tube 10, and the cold airflow enters the cooling zone 12 from the cold end outlet.

[0040] Meanwhile, the waste saponification liquid generated during the surface treatment process before wire drawing is fed into the heating metal coil 71 through a pipeline. The temperature of the waste saponification liquid in the heating metal coil 71 is increased through convection heat transfer. The heated waste saponification liquid is directly transported to the wire drawing die box 1, where it submerges the wire located at the bottom reversing roller 16. At the same time, hot air from the heating zone 11 enters the hollow disc 72 through the air inlet one-way valve 74 and is finally sprayed into the waste saponification liquid inside the wire drawing die box 1 through the one-way air nozzle 73. The solubility of waste saponification liquid increases with temperature. Simultaneously, the increased temperature increases the kinetic energy of molecules in the waste saponification liquid, enhancing its penetration and scouring ability on the steel wire surface for lubricating powder residues. This accelerates the dissolution of the lubricating powder residues, making them easier to detach from the steel wire surface and improving the cleaning effect. If the lubricating powder contains grease, the heated waste saponification liquid can soften or even liquefy the grease components, reducing their adhesion to the steel wire surface. Simultaneously, it consumes the grease components, facilitating the demulsification process using acid and neutralization using alkali. The reduced raw material consumption in the wire drawing process further improves the cleaning effect of the steel wire and also lubricates the surface of the steel wire, allowing it to pass smoothly through the drawing die 2 for the final drawing process. In addition, the hot air ejected through the one-way nozzle 73 further enhances the kinetic energy of the waste saponification liquid inside the drawing die box 1, effectively improving the cleaning effect of the waste saponification liquid on the surface of the steel wire. This significantly reduces the residue on the surface of the steel wire from clogging the heat exchanger in the heat treatment furnace during the heat treatment process, improves the heat exchange effect, and saves natural gas. This mechanism not only enables the device to efficiently clean the surface residue of steel wire produced by the straight-in wire drawing machine, but also reduces the risk of heat exchanger blockage in the next heat treatment process, thereby improving the heat exchanger efficiency, enhancing the energy-saving and environmental protection performance of steel wire production, improving the continuity and efficiency of steel wire processing, and fully consuming the waste saponification liquid generated in the previous surface treatment process. It also optimizes the chemical treatment process of adding acid to break emulsion and adding alkali to neutralize, avoiding material waste.

[0041] After the waste saponification liquid in the wire drawing die box 1 cleans the residue on the surface of the steel wire, it enters the cooling metal coil 81 through the drain hole 15. At this time, the cooling metal coil 81 is affected by the low temperature air in the cooling zone 12 and its temperature is reduced. The temperature of the waste saponification liquid in the cooling metal coil 81 is reduced by convection heat transfer. At low temperature, the Brownian motion of colloidal particles weakens and the charge repulsion force decreases, making it easier to coagulate or flocculate, thus accelerating solid-liquid separation. At the same time, some impurities dissolved in the waste saponification liquid may have reduced solubility due to the low temperature, resulting in the precipitation of solid impurities. This will then form larger particles of precipitate, separating the waste residue from the waste saponification liquid. Afterward, the waste saponification liquid carrying the large particles of waste residue is transported to the conical composite filter hopper 92. Due to the control of the PLC controller 76, the drive motor 97 is started. The drive motor 97 drives the guide tube 94 to rotate rapidly through the gear 98 and the external gear ring 95 (the transmission ratio of the gear 98 and the external gear ring 95 is 3:1). The guide tube 94 drives the conical composite filter hopper 92 to rotate rapidly. The conical composite filter cartridge 92 rotates rapidly in the connecting bearing 91, generating centrifugal force. This centrifugal force accelerates the separation of waste saponification liquid and waste residue injected into the conical composite filter cartridge 92. The waste residue does not need to be left to stand for classification, improving the efficiency of waste residue separation. The separated waste residue, assisted by the low-temperature air sprayed from the bent pipe 99, quickly enters the waste residue dryer 5 along the inner wall of the conical composite filter cartridge 92 and the guide tube 94. At the same time, the scraping effect of the scraper strip 19 can prevent the waste residue from adhering to the inside of the conical composite filter cartridge 92 and causing filter blockage. The drying capacity of the waste residue dryer 5 is controlled by the PLC controller 76. The dried waste residue is discharged into the collection container through the waste residue dryer 5 and finally outsourced for processing. Meanwhile, the waste saponification liquid is thrown out by centrifugal force and accumulates at the bottom of the treatment tank 3. Finally, it is discharged into the collection container through the drain hose 910 for outsourced processing. This mechanism enables the device to quickly separate solid impurities in the waste saponification liquid after cleaning, making it more convenient to outsource the waste saponification liquid and waste residue.

[0042] During the cleaning of steel wire in the wire drawing die 1 using waste saponification liquid, temperature sensor 75 monitors the temperature of the waste saponification liquid in real time and converts the detected temperature value into an electrical signal, which is then sent to PLC controller 76. If the temperature of the waste saponification liquid does not reach the preset effective cleaning temperature (e.g., 50 degrees Celsius) of PLC controller 76, PLC controller 76 controls the frequency converter of air compressor pump 79. The frequency converter controls the pump speed of air compressor pump 79, thereby regulating the pressure of compressed air output by air compressor pump 79 (the pressure gradually increases from 0.5MPa to 0.8MPa until the temperature reaches the target), and adjusting the pressure of the compressed air entering the wire drawing die 1. The temperature of the waste saponification liquid meets the requirements and ensures the cleaning effect of the steel wire. The higher the pressure of the compressed air, the higher the temperature of the hot air generated by the vortex tube 10 and the lower the temperature of the cold air. Conversely, the effect is the opposite. This is because when the pressure increases, the kinetic energy carried by the compressed air increases, and the vortex formed after acceleration by the guide vanes rotates more violently. The energy of the outer hot airflow is more fully concentrated (higher temperature), and the inner cold airflow is lower in temperature because more energy is stripped away. Conversely, when the pressure decreases, the kinetic energy of the airflow is insufficient, the vortex separation effect weakens, and the temperature difference between the hot and cold airflows decreases accordingly. This mechanism enables the device to have an automatic adjustment function, ensuring a reliable cleaning effect of the residue on the steel wire surface.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
