Description

Technical Field

[0001] This utility model relates to the field of degreasing equipment technology, and in particular to a degreasing device for stainless steel strips. Background Technology

[0002] Stainless steel strip refers to a narrow and long steel plate manufactured to meet the needs of various industrialized metal or mechanical products. Currently, after rolling, stainless steel strips have a large amount of oil adhering to their surface. If this oil is not removed in time, it will affect subsequent packaging and winding. Therefore, we urgently need a degreasing device for stainless steel strips.

[0003] Currently, the degreasing process for stainless steel strips includes soaking, washing, and drying. First, the stainless steel strip is soaked in an alkaline liquid (e.g., NaOH) to react with the oil adhering to it. Then, the strip is washed and finally dried. This process achieves degreasing. However, during the soaking process, the stainless steel strip is first placed in a soaking tank containing alkaline liquid, and then removed after soaking. This has several drawbacks: firstly, alkaline liquid drips out after removal, resulting in waste; secondly, soaking before washing affects the degreasing efficiency. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides an oil removal device for stainless steel strips. By improving the oil removal method of stainless steel strips, the waste of alkaline liquid can be avoided, and the oil removal efficiency of stainless steel strips can be improved at the same time.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An oil removal device for stainless steel strip includes: an unwinding mechanism, a spraying mechanism, a cleaning mechanism, a drying box, and a winding mechanism arranged sequentially along the moving direction of the stainless steel strip. The spraying mechanism includes: two vertically arranged spray pipes, which are arranged opposite to each other. When performing oil removal on the stainless steel strip, the two spray pipes are located on both sides of the stainless steel strip. The spray pipes have multiple spray holes on the side closer to the stainless steel strip. The multiple spray holes are distributed sequentially along the vertical direction, and the diameter of the multiple spray holes decreases sequentially from top to bottom along the vertical direction.

[0007] Therefore, by spraying alkaline liquid onto the stainless steel strip through spray holes, it comes into contact with the oil adhering to the stainless steel strip. Compared with the existing soaking method, this method has a simpler structure, is easier to operate, and avoids the waste of alkaline liquid. At the same time, the spray holes with progressively smaller diameters can ensure that the alkaline liquid is evenly adhered to the surface of the stainless steel strip, further avoiding waste. In addition, the unwinding mechanism, spraying mechanism, cleaning mechanism, drying box, and winding mechanism, which are arranged sequentially along the moving direction of the stainless steel strip, do not need to move the stainless steel strip during the degreasing process. They only need to move from the unwinding mechanism to the winding mechanism, thereby improving the degreasing efficiency of the stainless steel strip.

[0008] As a further improvement to the above technical solution, it also includes: a frame, wherein the unwinding mechanism, the liquid spraying mechanism, the cleaning mechanism, the drying box and the winding mechanism are all connected to the frame.

[0009] As a further improvement to the above technical solution, the spraying mechanism further includes: a first support base, a first liquid storage tank, a first connecting pipe, and a first valve. The first support base is connected to the frame, the spraying pipe is located inside the first support base, the first liquid storage tank is located outside the first support base and connected to it, and the first liquid storage tank is used to store alkaline liquid. The first connecting pipe passes through the first support base, and both ends of the first connecting pipe are respectively connected to the spraying pipe and the first liquid storage tank. The first valve is located outside the first support base and is connected in series with the first connecting pipe. Thus, during degreasing, the first valve is opened, and the alkaline liquid in the first liquid storage tank passes sequentially through the first connecting pipe and the spraying pipe, and finally sprays out through the spraying hole onto the surface of the stainless steel strip.

[0010] As a further improvement to the above technical solution: the cleaning mechanism includes a second support base, multiple water spray pipes, and multiple cleaning brushes. The second support base is connected to the frame. The water spray pipes and cleaning brushes are both located within the second support base. Each water spray pipe corresponds to one cleaning brush, and the water spray pipes and cleaning brushes are spaced apart along the moving direction of the stainless steel strip. Each water spray pipe has multiple spray holes, and each cleaning brush is rotatably connected to the second support base. Therefore, this design of multiple water spray pipes and multiple cleaning brushes arranged at intervals allows for multiple cleaning operations on the stainless steel strip to thoroughly remove the oil adhering to it, thereby improving the degreasing effect of the stainless steel strip.

[0011] As a further improvement to the above technical solution, the cleaning mechanism further includes: a second liquid storage tank, a second connecting pipe, and a second valve. The second liquid storage tank is located outside and connected to the second support base. The second liquid storage tank is used to store clean water. The second connecting pipe passes through the second support base, and both ends of the second connecting pipe are respectively connected to the water spray pipe and the second liquid storage tank. The second valve is located outside the second support base and connected in series with the second connecting pipe. Thus, during degreasing, the second valve is opened, and the clean water in the second liquid storage tank passes through the second connecting pipe and the water spray pipe in sequence, and finally sprays out through the water spray hole, spraying onto the surface of the stainless steel strip. Then, the rotating cleaning brush is used to achieve the cleaning operation of the stainless steel strip.

[0012] As a further improvement to the above technical solution: the first support base is a hollow structure, and both ends of the first support base are provided with first through holes.

[0013] As a further improvement to the above technical solution: the cleaning brush has a hollow structure, and a second through hole is provided at both ends of the second support base.

[0014] As a further improvement to the above technical solution: the unwinding mechanism has the same structure as the winding mechanism.

[0015] As a further improvement to the above technical solution: the unwinding mechanism includes: a first driving component, an expansion shaft, a support plate, and a second driving component. The first driving component is connected to the frame via a third support base. The driving end of the first driving component is connected to the expansion shaft. The support plate is located outside the driving end of the first driving component. Two second driving components are located on both sides of the first driving component. The second driving components are connected to the frame, and the driving end of the second driving component is connected to the support plate. Therefore, the rotation of the expansion shaft is controlled by the first driving component to realize the rotation of the first and second winding machines, thereby realizing the unwinding and winding operations of the stainless steel strip; the installation and disassembly of the first and second winding machines are realized by adjusting the expansion and contraction of the expansion shaft, thereby realizing the installation and disassembly of the stainless steel strip; the cooperation between the second driving component and the support plate can support the first and second winding machines, ensuring that the first and second winding machines will not fall when the expansion shaft is in the retracted state. At the same time, the cooperation between the second driving component and the support plate can also drive the first and second winding machines to move up and down, so as to facilitate the installation and disassembly of the first and second winding machines. In addition, the cooperation between the second driving component and the support plate can also ensure that the center lines of the first and second winding machines are collinear, so as to facilitate the unwinding and winding of the stainless steel strip.

[0016] As a further improvement to the above technical solution: the frame is provided with a drainage trough and a drainage pipe, and the drainage trough is connected to the drainage pipe. Thus, wastewater from the oil removal process flows into the drainage trough and is discharged through the drainage pipe, preventing indiscriminate discharge of wastewater and thus avoiding pollution.

[0017] The beneficial effects of this utility model are as follows:

[0018] Alkaline liquid is sprayed onto the stainless steel strip through spray holes, bringing it into contact with the oil adhering to the strip. Compared to existing soaking methods, this method is simpler in structure, easier to operate, and avoids waste of alkaline liquid. Furthermore, the progressively smaller nozzle diameters of the spray holes ensure uniform adhesion of the alkaline liquid to the surface of the stainless steel strip, further minimizing waste. The unwinding mechanism, spraying mechanism, cleaning mechanism, drying chamber, and winding mechanism, arranged sequentially along the strip's movement direction, allow the stainless steel strip to move only from the unwinding mechanism to the winding mechanism during degreasing, thus improving the degreasing efficiency.

[0019] This utility model also has the following advantages:

[0020] 1. The design of multiple water spray pipes and multiple cleaning brushes arranged at intervals in this utility model can perform multiple cleaning operations on stainless steel strips to thoroughly clean the oil adhering to the stainless steel strips, thereby improving the degreasing effect of stainless steel strips.

[0021] 2. This utility model controls the rotation of the expansion shaft through the first driving component to realize the rotation of the first winding machine and the second winding machine, thereby realizing the unwinding and winding operations of the stainless steel strip.

[0022] 3. This utility model achieves the installation and disassembly of the first winding machine and the second winding machine by adjusting the expansion and contraction of the expansion and contraction shaft, thereby achieving the installation and disassembly of the stainless steel strip.

[0023] 4. In this utility model, the wastewater during the oil removal process flows into the drainage tank and is discharged through the drainage pipe to avoid indiscriminate discharge of wastewater and cause pollution. Attached Figure Description

[0041] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0042] like Figures 1 to 7The figure shown is the preferred embodiment of the present invention. The degreasing device for stainless steel strip in this embodiment includes: an unwinding mechanism 1, a spraying mechanism 2, a cleaning mechanism 3, a drying box 4, and a winding mechanism 5 arranged sequentially along the moving direction of the stainless steel strip. The spraying mechanism 2 includes: two vertically arranged spraying pipes 201, which are arranged opposite to each other. When the stainless steel strip is degreased, the two spraying pipes 201 are located on both sides of the stainless steel strip. The spraying pipes 201 have multiple spraying holes 202 on the side closer to the stainless steel strip. The multiple spraying holes 202 are distributed sequentially along the vertical direction, and the diameter of the multiple spraying holes 202 decreases sequentially from top to bottom along the vertical direction. Therefore, by spraying alkaline liquid onto the stainless steel strip through the spray holes 202, the liquid comes into contact with the oil adhering to the stainless steel strip. Compared with the existing soaking method, this method has a simpler structure, is easier to operate, and avoids the waste of alkaline liquid. At the same time, the spray holes 202 with progressively smaller diameters can achieve uniform adhesion of alkaline liquid to the surface of the stainless steel strip, further avoiding waste of alkaline liquid. In addition, the unwinding mechanism 1, spraying mechanism 2, cleaning mechanism 3, drying box 4, and winding mechanism 5, which are arranged sequentially along the moving direction of the stainless steel strip, do not need to move the stainless steel strip during the degreasing process. They only need to move from the unwinding mechanism 1 to the winding mechanism 5, thereby improving the degreasing efficiency of the stainless steel strip.

[0043] In other words, as the diameter of the spray nozzle 202 gradually decreases, the alkaline liquid sprayed on the stainless steel strip will be uneven. However, because the alkaline liquid will flow downwards due to gravity, the uneven distribution will become a uniform distribution, thus preventing the waste of alkaline liquid.

[0044] In this embodiment, the machine also includes: a frame 6, an unwinding mechanism 1, a spraying mechanism 2, a cleaning mechanism 3, a drying box 4, and a winding mechanism 5, all of which are connected to the frame 6.

[0045] In this embodiment, the spraying mechanism 2 further includes: a first support base 203, a first liquid storage tank 204, a first connecting pipe 205, and a first valve 206. The first support base 203 is connected to the frame 6. The spraying pipe 201 is located inside the first support base 203. The first liquid storage tank 204 is located outside the first support base 203 and is connected to the first support base 203. The first liquid storage tank 204 is used to store alkaline liquid. The first connecting pipe 205 passes through the first support base 203, and both ends of the first connecting pipe 205 are connected to the spraying pipe 201 and the first liquid storage tank 204, respectively. The first valve 206 is located outside the first support base 203 and is connected in series with the first connecting pipe 205. The first support base 203 has a hollow structure, and both ends of the first support base 203 are provided with first through holes 207. Therefore, during degreasing, the first valve 206 is opened, and the alkaline liquid in the first storage tank 204 passes through the first connecting pipe 205 and the spray pipe 201 in sequence, and is finally sprayed out through the spray hole 202 onto the surface of the stainless steel strip.

[0046] In this embodiment, the cleaning mechanism 3 includes: a second support base 301, multiple water spray pipes 302, multiple cleaning brushes 303, a second liquid storage tank 305, a second connecting pipe 306, and a second valve 307. The second support base 301 is connected to the frame 6. The water spray pipes 302 and cleaning brushes 303 are all located inside the second support base 301. The water spray pipes 302 and cleaning brushes 303 correspond one-to-one, and the water spray pipes 302 and cleaning brushes 303 are spaced apart along the moving direction of the stainless steel strip. The water spray pipes 302 have multiple water spray holes 304, and the cleaning brushes 303 and... The second support base 301 is rotatably connected, the second liquid storage tank 305 is located outside the second support base 301 and connected to the second support base 301, the second liquid storage tank 305 is used to store clean water, the second connecting pipe 306 passes through the second support base 301, and the two ends of the second connecting pipe 306 are respectively connected to the water spray pipe 302 and the second liquid storage tank 305, the second valve 307 is located outside the second support base 301 and is connected in series on the second connecting pipe 306; the cleaning brush 303 has a hollow structure, and the two ends of the second support base 301 are provided with second through holes 308. Therefore, the design of multiple water spray pipes 302 and multiple cleaning brushes 303 arranged at intervals can perform multiple cleaning operations on the stainless steel strip to thoroughly remove the oil adhering to the stainless steel strip, thereby improving the degreasing effect of the stainless steel strip. During degreasing, the second valve 307 is opened, and the clean water in the second liquid storage tank 305 passes through the second connecting pipe 306 and the water spray pipe 302 in sequence, and is finally sprayed out through the water spray hole 304, spraying it on the surface of the stainless steel strip. Then, the rotating cleaning brushes 303 are used to achieve the cleaning operation of the stainless steel strip.

[0047] In this embodiment, the unwinding mechanism 1 and the winding mechanism 5 have the same structure. The unwinding mechanism 1 includes: a first driving member 101, a tension shaft 102, a support plate 104, and a second driving member 105. The first driving member 101 is connected to the frame 6 through a third support base 103. The driving end of the first driving member 101 is connected to the tension shaft 102. The support plate 104 is located outside the driving end of the first driving member 101. The two second driving members 105 are located on both sides of the first driving member 101. The second driving members 105 are connected to the frame 6, and the driving end of the second driving member 105 is connected to the support plate 104. Therefore, the rotation of the expansion shaft 102 is controlled by the first driving component 101 to realize the rotation of the first winding machine and the second winding machine, thereby realizing the unwinding and winding operations of the stainless steel strip; the expansion and contraction adjustment of the expansion shaft 102 is used to realize the installation and disassembly of the first winding machine and the second winding machine, thereby realizing the installation and disassembly of the stainless steel strip; the cooperation between the second driving component 105 and the support plate 104 can support the first winding machine and the second winding machine, ensuring that the first winding machine and the second winding machine will not fall when the expansion shaft 102 is in the retracted state. At the same time, the cooperation between the second driving component 105 and the support plate 104 can also drive the first winding machine and the second winding machine to move up and down, so as to facilitate the installation and disassembly of the first winding machine and the second winding machine. In addition, the cooperation between the second driving component 105 and the support plate 104 can also make the center line of the first winding machine and the center line of the second winding machine collinear, so as to facilitate the unwinding and winding of the stainless steel strip.

[0048] For example, the first driving component 101 is an electric motor, and the second driving component 105 is a cylinder.

[0049] In this embodiment, the frame 6 is provided with a drainage trough 601 and a drainage pipe 602, and the drainage trough 601 and the drainage pipe 602 are connected. Thus, the wastewater in the oil removal process flows into the drainage trough 601 and is discharged through the drainage pipe 602, so as to avoid the indiscriminate discharge of wastewater and cause pollution.

[0050] The degreasing process of the stainless steel strip of this utility model is as follows: First, the stainless steel strip to be degreased is installed on the unwinding mechanism 1 along with the first winding machine, and the second winding machine is installed on the winding mechanism 5, so that the two expansion shafts 102 fix the first winding machine and the second winding machine respectively, and the center line of the first winding machine and the center line of the second winding machine are collinear; finally, the first driving component 101 is started, and the first valve 206 and the second valve 307 are opened, so that the stainless steel strip gradually moves from the first winding machine to the second winding machine, and passes through the spraying mechanism 2 in sequence. The cleaning mechanism 3 and the drying chamber 4 spray alkaline liquid onto the surface of the stainless steel strip through the spray mechanism 2, so that the alkaline liquid comes into contact with the oil phase adhering to the surface of the stainless steel strip and reacts. Clean water is sprayed onto the surface of the stainless steel strip through the water spray pipe 302, and the surface of the stainless steel strip is cleaned by the rotating cleaning brush 303. The stainless steel strip is dried by the drying chamber 4 after cleaning, thus realizing the degreasing operation of the stainless steel strip. The wastewater in the degreasing process flows into the drainage tank 601 and is discharged through the drainage pipe 602.

[0051] In summary, this invention sprays alkaline liquid onto the stainless steel strip through the spray holes 202, allowing it to come into contact with the oil adhering to the stainless steel strip. Compared to existing soaking methods, this method has a simpler structure, is easier to operate, and avoids the waste of alkaline liquid. Furthermore, the progressively smaller diameter of the spray holes 202 ensures that the alkaline liquid adheres evenly to the surface of the stainless steel strip, further preventing waste. Additionally, the unwinding mechanism 1, spraying mechanism 2, cleaning mechanism 3, drying box 4, and winding mechanism 5, arranged sequentially along the moving direction of the stainless steel strip, eliminate the need for the stainless steel strip to move during the degreasing process; it only needs to move from the unwinding mechanism 1 to the winding mechanism 5, thereby improving the degreasing efficiency of the stainless steel strip.
