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.

[0018] Compared with the prior art, the straight type wire drawing machine on-line cleaning steel wire device has the advantages that:

[0019] 1. By setting the waste soap solution heating mechanism, vortex tube, drawing die box and processing box, when the steel wire is in the last drawing process in the straight drawing machine, the steel wire passes through the drawing die box and the drawing die, then the PLC controller injects compressed air into the vortex tube through the air compressor pump, generates hot air injection into the heating area, and produces low temperature air injection into the cooling area. At the same time, the waste saponification solution generated by the surface treatment process before drawing through the pipeline is input into the heating metal coil to improve the temperature. The waste saponification solution and hot air after heating are injected into the drawing die box, realizing efficient cleaning of the steel wire surface in the drawing die box. If the lubricating powder contains oil components, the waste saponification solution after heating can soften or even liquefy the oil components, reduce the adhesion to the steel wire surface, and consume the oil components, significantly reducing the residue of the steel wire surface to block the heat exchanger in the heat treatment process. The mechanism makes the device not only has the ability to clean the surface residue of the steel wire produced by the straight drawing machine, but also can reduce the risk of the heat exchanger being blocked in the next heat treatment process, and improve the continuity and efficiency of the steel wire processing, and can fully consume the waste saponification solution generated in the previous surface treatment process, and optimize the chemical treatment process of adding acid to break emulsion and adding alkali to neutralize.

[0020] 2. By setting the cooling mechanism and soap solution impurity separation mechanism, after the waste saponification solution in the drawing die box cleans the steel wire surface residue, it will enter the cooling mechanism to reduce the temperature. At low temperature, the Brownian motion of colloidal particles is weakened, the charge repulsion is reduced, and coagulation or flocculation is more likely to occur, accelerating solid-liquid separation. Then the waste saponification solution carrying large particle waste residue is transported to the soap solution impurity separation mechanism for rapid separation by centrifugal force. The waste residue does not need to be stationary for classification. The separated waste residue is quickly introduced into the waste residue dryer along the inner wall of the conical composite filter core and the conduit under the assistance of low-temperature air sprayed by the elbow. The dried waste residue is discharged into the collection container for outsourcing treatment, and the waste saponification solution is thrown out by centrifugal force and accumulated at the bottom of the processing box. Finally, it is discharged into the collection container for outsourcing treatment through the liquid discharge hose. The mechanism makes the device have the function of rapid separation of solid impurities in the waste saponification solution after cleaning, making the outsourcing treatment of waste saponification solution and waste residue more convenient.

[0021] 3. By setting the temperature sensor and PLC controller, the temperature sensor will detect the temperature of the waste saponification solution in real time during the cleaning of the steel wire in the drawing die box, and convert the detected temperature value into an electrical signal and transmit it to the PLC controller. If the temperature of the waste saponification solution does not reach the effective cleaning temperature preset by the PLC controller, the PLC controller adjusts the temperature of the hot air by controlling the pressure of the compressed air output by the air compressor pump to adjust the temperature of the waste saponification solution entering the drawing die box to meet the requirements and ensure the cleaning effect of the steel wire. The mechanism makes the device have the function of automatic adjustment, ensuring the reliable cleaning effect of the steel wire surface residue. BRIEF DESCRIPTION OF DRAWINGS

[0038] The temperature sensor 75 is electrically connected with the input end of the PLC controller 76 through wires. The waste residue dryer 5, the air compression air pump 79 and the driving motor 97 are all electrically connected with the output end of the PLC controller 76 through wires. The above power supply equipment and electrical connections are all prior art, which will not be repeated here.

[0039] The operation principle of the application is described as follows: when the steel wire is subjected to the last drawing process in the straight drawing machine, the steel wire is threaded through the drawing die box 1 and the drawing die 2, and the steel wire is further wound around the five reversing rollers 16 in sequence to form a W-shaped path, then the PLC controller 76 controls the air compression pump 79 to start, the compressed air of the air compression pump 79 is injected into the vortex tube 10 through the connecting pipe 710, the compressed air (the pressure is usually 0.3-1.0 MPa) is accelerated by the guide blade and forms a high-speed rotating vortex, and the airflow is separated into an outer layer of high-speed rotating hot airflow and an inner layer of low-speed rotating cold airflow due to the vortex effect, 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] At the same time, the waste saponification liquid generated in the surface treatment process before drawing is input into the heating metal coil pipe 71 through the pipeline, the temperature of the waste saponification liquid in the heating metal coil pipe 71 is raised in the form of convection heat exchange, and the heated waste saponification liquid is directly delivered to the drawing die box 1, the waste saponification liquid will submerge the steel wire at the bottom reversing roller 16, at the same time, the hot air in the heating zone 11 enters the hollow disc 72 through the air inlet one-way valve 74, and finally enters the waste saponification liquid in the drawing die box 1 through the one-way air nozzle 73, when the temperature of the waste saponification liquid is raised, the solubility is improved, at the same time, the temperature rise will increase the kinetic energy of the molecules in the waste saponification liquid, enhance the penetration and flushing capacity of the waste saponification liquid to the surface attachments (lubricating powder) of the steel wire, accelerate the dissolution of the lubricating powder residues, make it easier to separate from the surface of the steel wire, improve the cleaning effect, if the lubricating powder contains grease components, the waste saponification liquid after heating can soften or even liquefy the grease components, reduce the adhesion to the surface of the steel wire, at the same time, consume the grease components, so that the raw material consumption in the chemical treatment process of adding acid to break emulsion and adding alkali to neutralize is reduced, further improve the cleaning effect of the steel wire, and the steel wire can also be lubricated on the surface, so that the steel wire can smoothly pass through the drawing die 2 for the last drawing process, in addition, after the hot air is sprayed out through the one-way air nozzle 73, the kinetic energy of the waste saponification liquid in the drawing die box 1 is further improved, the cleaning effect of the waste saponification liquid to the surface of the steel wire is effectively improved, the surface attachments of the steel wire are significantly reduced, the heat exchanger in the heat treatment furnace in the heat treatment process is not blocked, the heat exchange effect is improved, and the natural gas is saved, the device not only has the ability to clean the surface residues of the steel wire produced by the straight drawing machine efficiently, but also can reduce the risk of the heat exchanger being blocked in the next heat treatment process, thereby improving the heat exchange efficiency of the heat exchanger, improving the energy saving and environmental protection performance of the steel wire production, and improving the continuity and efficiency of the steel wire processing, and the waste saponification liquid generated in the previous surface treatment process can be fully consumed, the chemical treatment process of adding acid to break emulsion and adding alkali to neutralize is optimized, and the waste of materials is avoided;

[0041] When the old saponification solution in the drawing die box 1 is cleaned up the surface residue of the steel wire, it will enter into 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 of the cooling area 12 to reduce the temperature, through the form of convective heat transfer to reduce the temperature of the old saponification solution in the cooling metal coil 81, the Brownian motion of colloidal particles is weakened at low temperature, the charge repulsion is reduced, and the coagulation or flocculation is more likely to occur, the solid-liquid separation is accelerated, at the same time, the solubility of some impurities dissolved in the old saponification solution may be reduced due to the influence of low temperature, and the solid impurities are precipitated, then larger particle precipitates are formed, and the waste residue in the old saponification solution is separated, then the old saponification solution carrying large particle waste residue is transported to the conical composite filter core hopper 92, since the PLC controller 76 controls the driving motor 97 to start, the driving motor 97 drives the conduit 94 to rotate quickly through the gear 98 and the external tooth ring 95 (the transmission ratio of the gear 98 and the external tooth ring 95 is 3:1), the conduit 94 drives the conical composite filter core hopper 92 to rotate quickly in the connecting bearing 91, and generates centrifugal force, which can accelerate the separation of the waste residue in the old saponification solution injected into the conical composite filter core hopper 92, the waste residue does not need to be stationary, the efficiency of waste residue separation is improved, the separated waste residue enters the waste residue dryer 5 along the inner wall of the conical composite filter core hopper 92 and the conduit 94 under the assistance of the low temperature air sprayed by the elbow pipe 99, at the same time, the scraping effect of the scraper strip 19 can avoid the waste residue adhering to the inside of the conical composite filter core hopper 92 to cause 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 treatment, and the old saponification solution is thrown out by the centrifugal force, accumulated at the bottom of the treatment box 3, and finally discharged into the collection container through the drain hose 910 for outsourcing treatment, the mechanism makes the device have the function of quickly separating the solid impurities in the old saponification solution after cleaning, and makes the outsourcing treatment of the old saponification solution and the waste residue more convenient;

[0042] The temperature sensor 75 monitors the temperature of the waste saponification liquid in real time during the cleaning of the steel wire in the drawing die box 1, and converts the detected temperature value into an electrical signal and sends it to the 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 the PLC controller 76, the PLC controller 76 controls the frequency converter of the air compression air pump 79, the frequency converter controls the rotating speed of the pump of the air compression air pump 79, thereby realizing the regulation and control of the pressure of the compressed air output by the air compression air pump 79 (the pressure gradually increases from 0.5 MPa to 0.8 MPa until the temperature reaches the standard), adjusting the temperature of the waste saponification liquid entering the inside of the drawing die box 1 to meet the requirements, and ensuring the cleaning effect of the steel wire. The greater 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 after being accelerated by the guide vane, the vortex rotation is more intense, and the energy of the outer hot air flow is more fully collected (the temperature is higher), and the inner cold air flow has a lower temperature because more energy is stripped. Conversely, when the pressure decreases, the kinetic energy of the air flow is insufficient, the vortex separation effect is weakened, and the temperature difference between the cold and hot air flows decreases. The mechanism enables the device to have an automatic adjustment function, ensuring the reliable cleaning effect of the residual substances on the surface of the steel wire.

[0043] The above description is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
