[0002] A steel strand is a steel product composed of multiple steel wires twisted together. This structure gives the steel strand high strength and stiffness, enabling it to withstand large tensile and compressive forces and bending stresses. The production process of the steel strand includes twisting multiple steel wires in a spiral shape on a stranding machine, followed by stress relief through low-temperature tempering, and finally forming a single whole steel strand. The production of steel strands mainly includes processes such as raw material preparation, steel wire processing, strand forming, heat treatment, product inspection, and packaging for shipment. During the production of steel strands, a large amount of waste liquid is generated. Direct discharge will affect the external environment, and the waste liquid needs to be treated. In the prior art, when treating waste liquid, because the waste liquid contains metal particles, filtration is required to filter out the metal particles in the waste liquid.

[0020] Please refer to Figures 1-4 , this embodiment provides a technical solution: a waste liquid treatment device for steel wire production, including a treatment cylinder 1;

[0021] Processing cylinder 1: A filter plate 2 is respectively arranged inside it to filter metal particles in the waste liquid. A rotating column 3 is vertically slidably connected between ceramic sealing rings in the middle of the filter plate 2. Magnet plates 4 are respectively arranged on the outer arc surface of the rotating column 3. The magnet plates 4 are cooperatively installed with the filter plate 2. The ends of the magnet plates 4 are metal sections without magnetism. By driving the magnet plates 4 to rotate through the rotating column 3, using the magnetism of the magnet plates 4, the metal particles on the surface of the filter plate 2 are adsorbed to the lower surface of the magnet plates 4, cleaning the metal particles on the surface of the filter plate 2, avoiding the blockage of the filtering components by metal particles, and ensuring the treatment efficiency of the waste liquid. Collection boxes 5 are respectively arranged on the outer arc surface of the processing cylinder 1. The upper ends of the collection boxes 5 are respectively communicated with the discharge ports of the processing cylinder 1. Guide inclined plates 6 are arranged at the discharge ports on the inner arc surface of the processing cylinder 1. Inclined scraping plates 7 are arranged on the upper surfaces of the guide inclined plates 6. The inclined scraping plates 7 are cooperatively installed with the magnet plates 4. During the rotation of the magnet plates 4, the metal particles adsorbed on the lower surface of the magnet plates 4 are pushed and scraped by the inclined scraping plates 7, so that the metal particles move in a direction away from the rotating column 3. When the metal particles move to the metal section at the end of the magnet plate 4, the metal particles are not adsorbed by the magnetism and fall downward. The fallen metal particles enter the interior of the collection box 5 from the discharge port of the processing cylinder 1 under the guidance of the guide inclined plates 6, collecting the filtered metal particles in the waste liquid. A single-chip microcomputer 8 is arranged on the outer arc surface of the processing cylinder 1. The input end of the single-chip microcomputer 8 is electrically connected to an external power supply to control the start and stop of the whole device. A motor 9 is arranged at the upper end of the processing cylinder 1. A rotating cylinder 10 is arranged at the lower end of the output shaft of the motor 9. The rotating cylinder 10 is vertically slidably connected to the upper end of the rotating column 3. The input end of the motor 9 is electrically connected to the output end of the single-chip microcomputer 8. Starting the motor 9, the output shaft of the motor 9 drives the rotating cylinder 10 to rotate. Through the vertical sliding connection between the rotating cylinder 10 and the rotating column 3, the relative rotation between the rotating column 3 and the rotating cylinder 10 is restricted, so that the rotating cylinder 10 drives the rotating column 3 and the magnet plates 4 to rotate, providing power for the rotation of the rotating column 3. An electric push rod 11 is arranged at the upper end of the processing cylinder 1. A rotating plate 12 is arranged at the lower end of the telescopic end of the electric push rod 11. The rotating plate 12 is rotatably connected to the upper end of the rotating column 3. The input end of the electric push rod 11 is electrically connected to the output end of the single-chip microcomputer 8. Starting the electric push rod 11, the telescopic end of the electric push rod 11 drives the rotating plate 12 to move up and down. Through the relative rotation between the rotating plate 12 and the rotating column 3, the rotating column 3 and the magnet plates 4 are driven to move up a certain distance, adjusting the vertical position of the magnet plates 4. A water inlet pipe 14 is arranged on the upper surface of the processing cylinder 1. A water outlet pipe 15 is arranged on the lower surface of the processing cylinder 1. The water inlet pipe 14 and the water outlet pipe 15 are both communicated with the processing cylinder 1, facilitating the entry and exit of the waste liquid into and out of the interior of the processing cylinder 1. The pore diameter of the filter holes of the filter plate 2 decreases step by step from top to bottom, performing multi-stage filtration on the waste liquid and improving the treatment effect on the waste liquid. Drain pipes are arranged at the lower ends of the collection boxes 5. Filter meshes 13 are laid on the bottom walls of the collection boxes 5 to discharge the waste liquid entering the interior of the collection boxes 5 and ensure the storage of metal particles.

[0022] The working principle of a waste liquid treatment device for steel strand production provided by the present utility model is as follows: During the production of steel strands, the waste liquid generated in the production of steel strands enters the treatment cylinder 1 through the water inlet pipe 14. The filter plate 2 is used to filter the metal particles in the waste water. The filtered waste liquid is discharged through the water outlet pipe 15. During the filtration of the waste liquid, the motor 9 is started by the single-chip microcomputer 8. The output shaft of the motor 9 drives the rotating cylinder 10 to rotate. Through the vertical sliding connection between the rotating cylinder 10 and the rotating column 3, the relative rotation between the rotating column 3 and the rotating cylinder 10 is restricted, so that the rotating cylinder 10 drives the rotating column 3 and the magnet plate 4 to rotate. Using the magnetic force of the magnet plate 4, the metal particles on the surface of the filter plate 2 are adsorbed to the lower surface of the magnet plate 4. The electric push rod 11 is started, and the telescopic end of the electric push rod 11 drives the rotating plate 12 to move up and down. Through the relative rotation between the rotating plate 12 and the rotating column 3, the rotating column 3 and the magnet plate 4 are driven to move up a certain distance. At this time, during the rotation of the magnet plate 4, the inclined scraper 7 is used to push and scrape the metal particles adsorbed on the lower surface of the magnet plate 4, so that the metal particles move away from the rotating column 3. When the metal particles move to the non-magnetic metal section at the end of the magnet plate 4, the metal particles are not adsorbed by the magnetic force and fall downward. The fallen metal particles enter the collection box 5 through the discharge port of the treatment cylinder 1 under the guidance of the guiding inclined plate 6, and the metal particles filtered from the waste liquid are collected.

[0023] It should be noted that, in the above embodiments, the single-chip microcomputer 8 disclosed can be a single-chip microcomputer of the PIC16F1823-I / P model. The motor 9 and the electric push rod 11 can be freely configured according to the actual application scenario. The motor 9 can be a stepping reduction motor of the 42BYHJ01 model, and the electric push rod 11 can be an electric push rod of the ANT-52 model. The single-chip microcomputer 8 controls the motor 9 and the electric push rod 11 to work using the commonly used methods in the prior art.
