[0015] Reference Figure 1-4 A steel plate spray cleaning device includes a housing 1 and a steel plate 6. The inner side of the housing 1 is provided with a conveying roller 16 supporting the steel plate 6. One end of the conveying roller 16 can be provided with a driving device, which drives the steel plate 6 to move through a motor, or directly pushes and pulls the steel plate 6 for feeding and discharging. Conveyor belts are provided on both sides of the housing 1 to realize automated feeding and discharging. The inner side of the housing 1 is provided with a rinsing spray pipe and a cleaning brush. Multiple sets of rinsing spray pipes are provided and are set on both sides of the cleaning brush for rinsing and scrubbing the steel plate 6. The bottom of the housing 1 is provided with a sewage recovery tank for recycling the wastewater from rinsing the steel plate. The box 1 has passage openings on both sides corresponding to the steel plate 6 for the steel plate 6 to pass through. Water-blocking tape 5 is provided on the passage openings to prevent water from washing the steel plate 6 from flowing out and causing pollution to the work site. The passage openings are divided into inlet passage openings and outlet passage openings. One end of the housing 1 is equipped with a water supply pipe 3 corresponding to the rinsing nozzle. Clean water or cleaning fluid is introduced through a pressure pump for rinsing. The rinsing nozzle includes a low-pressure nozzle 31 and a high-pressure nozzle 32. There are multiple sets of low-pressure nozzles 31, which are respectively set on the upper and lower sides of the steel plate 6. Generally, two sets of low-pressure nozzles 31 are set on each of the upper and lower sides of the steel plate 6. The cleaning brush is located between the two sets of low-pressure nozzles 31. The high-pressure nozzle 32 is set on the upper side of the steel plate 6. For normal rinsing, the low-pressure nozzle 31 is used. The rated total flow rate of the low-pressure nozzle 31 is 47.5 cubic meters / hour, and the rated pressure is 3 bar, i.e., 0.3 MPa. The pressure of the high-pressure nozzle 32 is selected according to the type of dirt being rinsed. For example, when rinsing thin steel plates or easily deformable materials, the pressure is 0.5 MPa to 1.0 MPa to avoid deformation. When rinsing thick steel plates or high-pressure resistant materials, a pressure of 20 MPa to 35 MPa can remove loose rust and old paint; a pressure of 200 MPa to 250 MPa can peel off oxide scale and thick coatings. Multiple nozzles are provided on both the low-pressure nozzle 31 and the high-pressure nozzle 32. The nozzle spacing is 105mm. The angle between the nozzle and the steel plate 6 is 50-60°. The nozzles face the feed inlet side of the steel plate 6. The angle between the nozzle of the upper low-pressure nozzle 31 and the steel plate 6 is 50°, and the angle between the nozzle of the lower low-pressure nozzle 31 and the steel plate 6 is 60°, to ensure that the water flow can wash away dirt. The cleaning brush includes an upper cleaning brush 8 and a lower cleaning brush 9. The cleaning brush has a diameter of 200mm, a width of 2200mm, and nylon bristles with a diameter of 0.7mm and an effective length of 30mm. One end of the housing 1 is equipped with a power unit 4 corresponding to the cleaning brush. The power unit 4 includes a variable frequency motor 41, a reducer 42, and a universal coupling 43. Compared with mechanical speed regulation and DC speed regulation, the variable frequency motor 41 has a wider speed regulation range. The universal coupling 43 can transmit motion and torque and has different degrees of axial, angular compensation and radial compensation. The output shaft of the variable frequency motor 41 is connected to the reducer 42. The output shaft of the reducer 42 is connected to the cleaning brush through the universal coupling 43. There are two sets of universal couplings 43, which are respectively set to correspond to the upper cleaning brush 8 and the lower cleaning brush 9. The upper cleaning brush 8 and the lower cleaning brush 9 are driven by the variable frequency motor 41 to brush the steel plate 6. The inner side of the housing 1 is equipped with adjustment devices at both ends of the cleaning brush. The adjustment devices include a guide frame 11, a lower slider 12 and an upper slider 14. The two ends of the upper cleaning brush 8 are rotatably connected to the corresponding upper slider 14, and the two ends of the lower cleaning brush 9 are rotatably connected to the corresponding lower slider 12. The upper slider 14 and the lower slider 12 are slidably connected to the guide frame 11 to facilitate the adjustment of the position of the upper cleaning brush 8 and the lower cleaning brush 9. An adjustment screw 13 is provided on the lower side of the lower slider 12 so that the height of the lower slider 12 can be adjusted manually. The upper slider 14 is provided with a connecting rod 15. The top of both sides of the housing 1 is provided with a lifting mechanism 23 corresponding to the connecting rod 15. A linkage shaft 22 is provided between the two lifting mechanisms 23. A control motor 21 is provided at one end of the linkage shaft 22. Gears are provided at both ends of the linkage shaft 22. A rack is provided inside the lifting mechanism 23. The gears mesh with the rack. The lower end of the rack is fixedly connected to the connecting rod 15. The control motor 21 drives the linkage shaft 22 to rotate. The gears control the rack to move up and down. The height of the upper slider 14 is adjusted by the connecting rod 15. As needed, a position sensor is provided on one side of the rack to detect the rack height. This is used to assist in the height control of the upper slider 14 and realize automatic feedback adjustment. The inner side of the discharge port of the box 1 is provided with a scraper 17. The scraper 17 is made of rubber or plastic. The bottom of the scraper 17 abuts against the upper surface of the steel plate 6 to scrape off the water accumulated on the upper surface of the steel plate 6, so as to avoid carrying it out and causing pollution to the working environment. A visual inspection device 7 is provided on the top inner side of the box 1. As needed, an auxiliary visual inspection device 7 can be installed on the lower outer side of the discharge port of the box 1 to quickly detect the cleaning status of the lower surface of the steel plate 6. It is set on the outside of the box 1 to avoid the sewage from affecting the working status of the equipment. The visual inspection device 7 includes a lighting lamp and an image sensor. Through image recognition and visual inspection, the washing status of the steel plate 6 can be quickly checked. If dirt is still present, the steel plate 6 is transported back and washed using a high-pressure spray pipe 32.

[0016] In this embodiment, the steel plate 6 is fed into the box 1 through the feed inlet, with the dirty side facing upwards. The steel plate 6 moves on the conveyor roller 16, and clean water is supplied through the water supply pipe 3. It is rinsed through the low-pressure spray pipe 31. At the same time, the motor 21 drives the elevator 23, and the height of the upper slider 14 is adjusted through the connecting rod 15. The upper cleaning brush 8 is close to the steel plate 6, and the lower cleaning brush 9 is adjusted by manually adjusting the adjusting screw 13. The variable frequency motor 41 controls the rotation of the upper cleaning brush 8 and the lower cleaning brush 9 through the universal coupling 43 to brush the surface of the steel plate 6. The steel plate 6 is pulled to move towards the discharge inlet. The cleaning quality of the steel plate 6 is checked by the visual inspection device 7. If it is found that the dirt is not cleaned after the steel plate 6 is discharged, the steel plate 6 is pulled back, or the steel plate 6 is taken out, the dirty side is facing upwards, and it is rinsed again. If necessary, the high-pressure spray pipe 32 is used for rinsing.
