Description

Technical Field

[0001] This utility model relates to the field of silicon steel plate processing technology, and in particular to a device for cleaning oil stains on the surface of silicon steel plates. Background Technology

[0002] During the production and processing of silicon steel sheets, they come into contact with lubricating oil and other greases from the equipment, resulting in oil stains on the surface of the silicon steel sheets. This affects the quality of the silicon steel sheets, so the oil stains need to be removed before they leave the factory. Currently, oil stains are removed by cleaning with a cleaning solution followed by drying. However, in actual use, because the cleaning solution adheres to the surface of the silicon steel sheet, even after drying, although the water evaporates, chemical residues remain on the silicon steel sheet, affecting its quality and causing a decline in its quality. Therefore, there is an urgent need for a cleaning device that can remove oil stains from silicon steel sheets without leaving chemical residues. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a device for cleaning oil stains on the surface of silicon steel plates. This device can clean surface oil stains without leaving any chemical components of the cleaning agent on the silicon steel plate, thereby improving the quality of the silicon steel plate.

[0004] This utility model discloses a device for cleaning oil stains on the surface of silicon steel plates, including a housing. A steel plate inlet and a steel plate outlet are respectively provided on opposite side walls of the housing. A partition is provided inside the housing, dividing the interior into two independent chambers: a cleaning chamber near the steel plate inlet and a drying chamber near the steel plate outlet. A connecting opening is provided on the partition for the silicon steel plate to pass through. Guide rollers are provided on the housing within the cleaning chamber near the steel plate inlet and the connecting opening. Guide rollers are provided on the housing below the guide rollers. The silicon steel plate enters the cleaning chamber from the steel plate inlet and passes around the guide rollers in sequence. Rollers, guide rollers, and guide rollers enter the drying chamber through the connecting port and finally exit from the steel plate outlet. A brushing mechanism is installed on both sides of the silicon steel plate between the guide rollers and the guide rollers. Cleaning liquid nozzles are spaced apart on the brushing mechanism between the guide rollers and the guide rollers near the steel plate inlet, and these nozzles are connected to the outside of the chamber via pipes. Clean water nozzles are also spaced apart on the brushing mechanism between the guide rollers and the guide rollers near the connecting port, and these nozzles are also connected to the outside of the chamber via pipes. Fans are installed above and below the drying chamber, and the silicon steel plate passes between the fans. Heating tubes are arrayed between the fans and the silicon steel plate.

[0005] The structure of the brushing mechanism is as follows: a slide rail is horizontally placed inside the box, the slide rail is parallel to the corresponding silicon steel plate, a slider is set on the slide rail, a brush is set on the side of the slider facing the silicon steel plate, the length of the brush is greater than the width of the silicon steel plate, a drive motor is set at one end of the slide rail, a turntable is set at the output end of the drive motor, a pin is set around the turntable, a pin is also set at the end of the slider, the two pins are parallel, and the pins are also parallel to the output shaft of the drive motor, a connecting rod is set between the two pins, and the connecting rod is rotatably connected to the pins.

[0006] Air boxes are installed on the partitions above and below the connecting port. The length of the air box is greater than the width of the silicon steel plate. A long strip-shaped air outlet is installed at the top of the lower air box and a long strip-shaped air outlet is also installed at the bottom of the upper air box. The air outlets are arranged along the length of the air box and run through the entire length of the air box. The air outlets are inclined towards the silicon steel plate inside the cleaning box. A high-pressure air pipe is installed on the air box and extends to the outside of the box.

[0007] Two guide rollers are installed in the box below the guide rollers, spaced apart and at the same horizontal height. Cleaning rollers are installed in the boxes on both sides of the silicon steel plate between the guide rollers. The outer surface of the cleaning rollers is covered with bristles that contact the silicon steel plate. A drain pipe with a drain valve is installed at the bottom of the cleaning chamber. An overflow pipe is installed on the side wall of the cleaning chamber, and the height of the overflow pipe is the same as the middle part of the cleaning rollers below the silicon steel plate. The cleaning rollers are all driven by motors installed on the box.

[0008] The circumferential surface of the guide roller is provided with several annular grooves at intervals.

[0013] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0014] Example 1:

[0015] like Figure 1 As shown, this utility model discloses a device for cleaning oil stains on the surface of silicon steel plates, including a housing 1. A steel plate inlet 4 and a steel plate outlet 6 are respectively provided on opposite side walls of the housing 1. A partition is provided inside the housing 1, dividing the interior of the housing 1 into two independent chambers: the chamber near the steel plate inlet 4 is the cleaning chamber 2, and the chamber near the steel plate outlet 6 is the drying chamber 3. A connecting port 5 is provided on the partition, allowing the silicon steel plate 20 to pass through. Guide rollers 7 are provided on the housing 1 inside the cleaning chamber 2 near the steel plate inlet 4 and the connecting port 5. Guide rollers 8 are provided on the housing 1 below the guide rollers 7. The silicon steel plate 20 enters the cleaning chamber 2 from the steel plate inlet 4, passing sequentially around the guide rollers 7 and the guide rollers 8. Roller 8 and guide roller 7 enter the drying chamber 3 through the connecting port 5 and finally exit through the steel plate outlet 6. A brushing mechanism is provided on both sides of the silicon steel plate 20 between the guide roller 7 and the guide roller 8. Cleaning liquid nozzles 12 are spaced apart on the brushing mechanism between the guide roller 7 and the guide roller 8 near the steel plate inlet 4. The cleaning liquid nozzles 12 are connected to the outside of the chamber 1 through pipes. Clean water nozzles 13 are spaced apart on the brushing mechanism between the guide roller 7 and the guide roller 8 near the connecting port 5. The clean water nozzles 13 are connected to the outside of the chamber 1 through pipes. Fans 14 are provided above and below the drying chamber 3. The silicon steel plate 20 passes through the fans 14. Heating tubes 15 are arrayed between the fans 14 and the silicon steel plate 20.

[0016] The silicon steel sheet 20 is in coil form. An unwinding frame is installed on one side of the steel sheet inlet 4 of the housing 1, and a winding frame is installed on the other side of the steel sheet outlet 6 of the housing 1. The unwinding and winding frames are existing known structures. The winding frame is powered to rotate and wind the silicon steel sheet 20. The silicon steel sheet 20 enters the cleaning chamber 2 from the steel sheet inlet 4, first passing over the guide roller 7, then downwards over the guide roller 8, then upwards over the guide roller 7, passing through the connecting port 5 into the drying chamber 3, and finally exiting from the steel sheet outlet 6 before being wound up by the winding frame. A brushing mechanism is installed on both sides of the steel sheet between the guide roller 7 and the guide roller 8 at the steel sheet inlet 4, and a cleaning fluid nozzle 12 is installed on the brushing mechanism. External cleaning fluid can be delivered to the cleaning fluid nozzle 12 through pipes and a pump, and sprayed onto the silicon steel sheet 20. Combined with the brushing device, this facilitates the cleaning of oil stains from the silicon steel sheet 20. After being washed with the cleaning solution, the silicon steel plate 20 is conveyed to the space between the guide roller 7 and the guide roller 8 at the connecting port 5. A washing mechanism is also installed on both sides of the silicon steel plate 20 here, but this mechanism is equipped with clean water nozzles 13. Clean water from an external source is supplied to the clean water nozzles 13 through a pump and pipeline, spraying it onto the silicon steel plate 20. This, in conjunction with the washing mechanism, re-washes and removes the cleaning solution from the surface of the silicon steel plate 20. Simultaneously, because the silicon steel plate 20 is tilted upwards here, the water automatically flows downwards after washing, reducing the amount of water entering the drying chamber 3 and facilitating faster and simpler drying. Inside the drying chamber 3, the moisture on the surface of the silicon steel plate 20 is dried by the hot air delivered by the fan 14. Since almost no cleaning solution remains after being washed with clean water, the dried silicon steel plate 20 has a clean and high-quality surface. Furthermore, the large amount of water flowing directly downwards during the upward tilting process reduces moisture adhesion to the surface of the silicon steel plate 20, resulting in relatively lower drying power and reduced costs and drying time.

[0017] like Figure 2 As shown, the structure of the brushing mechanism is as follows: a slide rail 9 is horizontally placed inside the housing 1, the slide rail 9 is parallel to the silicon steel plate 20 at the corresponding position, a slider 10 is provided on the slide rail 9, and a brush 11 is provided on the side of the slider 10 facing the silicon steel plate 20. The length of the brush 11 is greater than the width of the silicon steel plate 20. A drive motor 23 is provided at one end of the slide rail 9, and a turntable 24 is provided at the output end of the drive motor 23. A pin 25 is provided around the turntable 24. A pin 25 is also provided at the end of the slider 10. The two pins 25 are parallel, and the pins 25 are also parallel to the output shaft of the drive motor 23. A connecting rod 26 is provided between the two pins 25, and the connecting rod 26 is rotatably connected to the pins 25.

[0018] In existing technology, a rotating brush 11 is used to brush the surface of the silicon steel plate 20. However, this method has the problem that the brush 11 may experience localized wear or uneven bristles after prolonged use, resulting in incomplete cleaning of certain areas during rotation. Therefore, this solution uses a slider 10 on a slide rail 9, which rotates via a turntable 24 on a drive motor 23, and a connecting rod 26 to achieve the reciprocating motion of the slider 10. The brush 11 is mounted on the slider 10, and the bristles of the brush 11 are in contact with the silicon steel plate 20. During the reciprocating motion of the slider 10, the bristles move back and forth, brushing the silicon steel plate 20. Combined with a cleaning solution, this effectively removes oil stains from the silicon steel plate 20. Since the length of the brush 11 is greater than the width of the silicon steel plate 20, and it is necessary to control the reciprocating amplitude of the slider 10 and the brush 11, it is necessary to ensure that the bristles of the brush 11 are always in full contact with the width of the silicon steel plate 20 during the reciprocating process. That is, during the brushing process, all parts of the silicon steel plate 20 in the width direction must always be in contact with the bristles, so that the cleaning is more thorough. At the same time, the bristles of different parts brush the silicon steel plate 20 during the brushing process, making the brushing more thorough and uniform. The drive motor 23 can be fixed inside the housing 1 or outside the housing 1. If it is fixed outside the housing 1, a hole needs to be opened in the housing 1 for the connecting rod 26 to pass through, and there should be no interference during the swinging of the connecting rod 26.

[0019] Air boxes 21 are installed on the partitions above and below the connecting port 5. The length of the air box 21 is greater than the width of the silicon steel plate 20. A long strip-shaped air outlet 22 is provided at the top of the lower air box 21 and at the bottom of the upper air box 21. The air outlets 22 are arranged along the length of the air box 21 and run through the entire length of the air box 21. The air outlets 22 are inclined towards the silicon steel plate 20 in the cleaning chamber 2. A high-pressure air pipe is installed on the air box 21 and extends to the outside of the box body 1. This is to further reduce the moisture on the silicon steel plate 20 entering the drying chamber 3. Air boxes 21 are installed on both the upper and lower sides of the connecting port 5. The air boxes 21 are connected to a high-pressure air source outside the box 1 through pipes. After the high-pressure air enters the air box 21, it is output from the air outlet 22. The high-pressure air output from the air outlet 22 impacts both sides of the silicon steel plate 20, which can wash away the moisture on the surface of the silicon steel plate 20 and evaporate some of the moisture, so that there is less moisture on the surface of the silicon steel plate 20 entering the drying chamber 3, which further reduces the power of the heating tube 15 and the fan 14 in the drying chamber 3.

[0020] Two guide rollers 8 are installed in the box 1 below the guide rollers 7. The two guide rollers 8 are spaced apart and are at the same horizontal height. Cleaning rollers 16 are installed in the box 1 on both sides of the silicon steel plate 20 between the guide rollers 8. The outer surface of the cleaning rollers 16 is covered with bristles, and the bristles of the cleaning rollers 16 are in contact with the silicon steel plate 20. A drain pipe 17 is installed at the bottom of the box 1 of the cleaning chamber 2. A drain valve 18 is installed on the drain pipe 17. An overflow pipe 19 is installed on the side wall of the box 1 of the cleaning chamber 2. The height of the overflow pipe 19 is the same as the height of the middle part of the cleaning rollers 16 below the silicon steel plate 20. The cleaning rollers 16 are all driven by a motor installed on the box 1.

[0021] Two spaced guide rollers 8 are installed below the guide rollers 7 to ensure that the silicon steel plate 20 between the guide rollers 8 is conveyed horizontally and at a low position. During normal brushing, the cleaning liquid and clean water flow downwards after brushing the silicon steel plate 20, so a mixture of cleaning liquid and clean water will accumulate at the bottom of the cleaning chamber 2. An overflow pipe 19 is installed on the side wall of the cleaning chamber 2 to allow a certain amount of cleaning liquid to accumulate in the cleaning chamber 2. The height of the overflow pipe 19 is designed so that the cleaning liquid is positioned in the middle of the lower cleaning roller 16, meaning that the lower cleaning roller 16 is partially submerged in the cleaning liquid. As the cleaning roller 16 rotates, it brushes the silicon steel plate 20. At the same time, the upper cleaning roller 16 rotates in conjunction with the flowing clean water and cleaning liquid mixture to brush the silicon steel plate 20 again, further improving the cleanliness. The brushed-off oil stains are above the water surface and can be discharged from the overflow pipe 19. After a certain period of time, the drain valve 18 can be opened to discharge sewage out through the drain pipe 17.

[0022] like Figure 3 As shown, the circumferential surface of the guide roller 8 is provided with a plurality of annular grooves 27 at intervals.

[0023] An annular groove 27 is provided on the guide roller 8 so that the clean water and cleaning liquid sprayed from the upper clean water nozzle 13 and cleaning liquid nozzle 12 can pass through the annular groove 27 and enter the silicon steel plate 20 between the two guide rollers as they flow down the silicon steel plate 20. This allows the cleaning roller 16 at that location to have sufficient mixed liquid to assist in brushing and improve the brushing effect.
