Technical Field

[0001] This utility model relates to the field of steel cable processing technology, and in particular to a pretreatment device for processing high-strength steel cables. Background Technology

[0002] In the pretreatment of high-strength steel cables before stranding and coating, chemical pickling or mechanical shot blasting is commonly used. Pickling generates large amounts of waste liquid and acid mist containing heavy metals, severely polluting the environment and jeopardizing operational safety. Mechanical treatment, on the other hand, easily forms microscopic scratches and stress concentration points on the cable surface, significantly reducing its fatigue strength, especially causing irreversible damage to ultra-high-strength steel wires. The industry urgently needs an environmentally friendly, non-destructive, continuous, and highly efficient integrated pretreatment device to overcome these bottlenecks.

[0003] A search revealed Chinese Patent Publication No. CN115739814A, which discloses a pretreatment device for high-strength steel cable processing. The device includes a cleaning box, a spraying box, and a drying box, all fixed to a strip-shaped base and arranged sequentially. A reversing frame is provided between the three boxes. The cleaning box is open and contains a cleaning tank and an ultrasonic cleaner. The spraying box has a material tank at the top and a recycling box at the bottom, and a spraying chamber with openings at both ends. The drying box has a drying chamber with openings at both ends, and air inlets and outlets are located on its upper and lower sides, respectively. The pretreatment device provided by this invention features an integrated structural design with functional modules for ultrasonic cleaning, spray recycling, and high-efficiency drying, ensuring smooth transitions between processes while achieving material savings and optimized processing efficiency.

[0004] However, the above solutions still have problems such as the lack of a rust removal step in the pretreatment process and a single cleaning process, which are insufficient to remove the oxide layer and impurities on the surface of the steel cable. Utility Model Content

[0005] The purpose of this utility model is to provide a pretreatment equipment for high-strength steel cable processing, which solves the problems of the lack of rust removal in the pretreatment process and the single cleaning process, resulting in insufficient ability to remove oxide layer and impurities on the surface of steel cables.

[0006] To achieve the above objectives, a pretreatment device for processing high-strength steel cables is provided, comprising a treatment box, a rust removal box, a cleaning box, and a drying box. The pretreatment box has a pretreatment chamber inside, and a fixed roller rotates inside the pretreatment chamber. Three fan-shaped nozzles are fixedly connected to both sides of the bottom of the pretreatment chamber, and an inclined groove is provided at the bottom of the pretreatment chamber.

[0007] The rust removal box has a rust removal chamber inside, and the rust removal chamber has an inner cavity. A vibrator is fixedly connected to the outside of the inner cavity, and the inner cavity is filled with ceramic beads of a specific particle size and hardness.

[0008] The cleaning box has a cleaning chamber inside, and several air-water mixing mist nozzles are fixedly connected inside the cleaning chamber. A storage bin is located at the top of the cleaning chamber.

[0009] The drying oven has a drying chamber inside, and several V-shaped drying grooves are fixedly connected to the top and bottom of the drying chamber. A heating chamber is opened at the top of the drying oven, and a heater is fixedly connected inside the heating chamber.

[0010] The pretreatment box, rust removal box, cleaning box, and drying box are all fixedly connected to a base.

Detailed Implementation

[0027] Reference Figure 1-4 This utility model relates to a pretreatment equipment for processing high-strength steel cables, which includes a pretreatment box 2, a rust removal box 4, a cleaning box 5, and a drying box 6. The pretreatment box 2 has a pretreatment chamber 10 inside, and a fixed roller 11 rotates inside the pretreatment chamber 10. Three fan-shaped nozzles 12 are fixedly connected to both sides of the bottom of the pretreatment chamber 10. An inclined groove 13 is opened at the bottom of the pretreatment chamber 10. After the steel cable enters the pretreatment chamber 10, the fixed roller 11 supports and guides its movement. The fan-shaped nozzles on both sides spray the pretreatment liquid in a mist, covering the surface of the steel cable and impacting and dissolving the oxide layer and impurities. The inclined groove design at the bottom of the pretreatment chamber facilitates the collection and discharge of waste liquid and impurities.

[0028] The rust removal box 4 has a rust removal chamber 16 inside, and an inner cavity 14 inside the rust removal chamber 16. A vibrator 15 is fixedly connected to the outside of the inner cavity 14. The inner cavity 14 is filled with ceramic beads of specific particle size and hardness. The vibrator 15 drives the inner cavity 14 to vibrate at high frequency, so that the ceramic beads remove stubborn rust on the surface of the steel cable through kinetic energy collision. Its spherical structure ensures no dead angle impact and does not damage the substrate.

[0029] The cleaning chamber 5 has a cleaning cavity 17, and several air-water mixed mist nozzles 19 are fixedly connected inside the cleaning cavity 17. A storage bin 18 is provided on the top of the cleaning cavity 17. The air-water mixed mist nozzles 19 use filtered air-water mixed mist to powerfully blow away abrasive particles, dust and debris remaining on the surface of the steel cable. A trace amount of surfactant is added to the water mist to enhance the cleaning effect.

[0030] The drying chamber 6 has a drying cavity 21. Several V-shaped drying grooves 23 are fixedly connected to the top and bottom of the drying cavity 21. The top of the drying chamber 6 has a heating cavity 20. A heater 22 is fixedly connected to the heating cavity 20. Hot air enters the drying cavity 21 through the guide structure. The V-shaped drying grooves 23 at the top and bottom form a specific airflow channel, so that the hot air is evenly distributed and fully contacts the surface of the steel cable. Moisture evaporation is achieved through convection heat transfer. The moving speed is adjusted according to the diameter of the steel cable during the drying process.

[0031] The pretreatment box 2, rust removal box 4, cleaning box 5 and drying box 6 are fixedly connected to the base 9. The base 9 adopts a rigid structure and the adjustable feet ensure that the equipment is installed horizontally. The base is equipped with wire grooves and pipe channels to achieve concealed layout of lines and pipes.

[0032] Four traction brackets 3 are fixed between the boxes on the base 9. Traction wheels 1 are rotatably connected to the traction brackets 3. A motor bracket 8 is fixedly connected to the end traction bracket 3. A motor 7 is fixedly connected to the motor bracket 8. The output shaft of the motor 7 is fixedly connected to the traction wheel 1 through a coupling. The traction brackets 3 are fixed to the base. The surface structure of the traction wheel increases the friction. The motor drives the end traction wheel through the coupling, which drives the steel cable through each box in sequence. The traction wheel group forms a tension control system. The motor speed is adjusted through feedback to ensure that the steel cable maintains constant tension during the pretreatment process and avoids stretching deformation.

[0033] A water outlet 25 is fixedly connected to the bottom left side of the pretreatment chamber 10. A valve port 24 is provided on the water outlet 25. The water outlet at the bottom of the pretreatment chamber 10 is connected to the bottom of the inclined trough. The valve port 24 is pneumatically controlled. When the waste liquid reaches the set liquid level, the valve port opens to discharge the waste liquid. When closed, the sealing ring ensures that the chamber is sealed to prevent liquid leakage.

[0034] A water tank 27 is fixedly connected to the base 9. The top of the water tank 27 is provided with a water inlet 26. The water tank 27 is fixedly connected to the cleaning tank 5. A high-pressure blower 28 is fixedly connected to the base 9. The high-pressure blower 28 is fixedly connected to the cleaning tank 5. The water tank 27 is connected to a water source through the water inlet 26. The high-pressure blower 28 is connected to the cleaning tank 5 to provide compressed air. A return pipe is provided between the cleaning tank and the water tank to realize the filtration and recycling of clean water.

[0035] A drying fan 29 is fixedly connected to the base 9. The drying fan 29 is fixedly connected to the drying box 6. The drying fan 29 and the drying box are connected to form a hot air circulation system, which sends the heated air into the drying chamber. The speed of the drying fan 29 is linked to the heating device for control.

[0036] During operation, the worker winds the steel cable around the traction wheel 1 and turns on the motor 7. The motor 7 drives the traction wheel 1 to rotate via a coupling. The steel cable first passes through the pretreatment chamber 10 in the pretreatment box 2. With the cooperation of the fixed roller 11, the steel cable passes through the area of ​​the fan-shaped nozzle 12, where cleaning fluid is sprayed, impacting the surface of the steel cable to dissolve and wash away oil stains. The inclined groove 13 at the bottom of the chamber collects the cleaning fluid, which is then collected at the outlet 25. Subsequently, the steel cable passes through the rust box 4. The steel cable passes through the inner cavity 14 at a uniform speed. The vibrator 15 generates high-frequency, low-amplitude vibrations, driving the abrasive particles in the cavity to produce intense but controlled movements. The abrasive particles continuously, evenly, and densely micro-impact and rub the surface and gaps of the steel cable, peeling off the oxide scale and rust layer. Next, the steel cable enters the cleaning chamber 17. Water and air supplied by the water tank 27 and the high-pressure blower 28 enter the storage bin 18, and then the mixture is sprayed out through the air-water mixture nozzle. 19. Powerful blowing removes residual abrasive particles, dust, and debris from the surface of the steel cable. Finally, the steel cable is transported to the drying chamber 21. The gas provided by the drying fan 29 is heated by the heater 22 and then evenly dried from the V-shaped drying tank 23, completing the pretreatment for steel cable processing. The entire process is then carried out by the ceramic bead abrasive impact rust removal driven by the vibrator 15, replacing the traditional pickling process. This process can completely remove the oxide scale and rust layer from the surface of the steel cable, remove impurities deep into the crevices without causing scratches, and fully preserve the strength and tensile properties of the steel cable. This solves the problems of pollution from chemical rust removal and damage to the substrate from mechanical rust removal. At the same time, the synchronous transmission system of the traction wheel 1 enables continuous processing of the steel cable throughout the entire process. In the pretreatment stage, the cleaning liquid is recovered and filtered through the inclined tank 13. In the cleaning stage, the air-water mixed mist nozzle 19 removes abrasive residue. In the drying stage, the V-shaped drying tank 23 guides hot air to improve energy efficiency, effectively solving the problems of excessive energy consumption and waste liquid disposal.
