Description

Technical Field

[0001] This utility model relates to the field of descaling technology, specifically to a cleaning system and a descaling system. Background Technology

[0002] Metal descaling refers to the process of removing oxide scale (oxide layer) or rust from the surface of metals, commonly used in the processing of metals such as steel, stainless steel, copper, and aluminum.

[0003] During the metal descaling process, steel grit, iron filings, or sludge may remain on the surface of the workpiece. If not cleaned, this can cause scratches, pits, or pitting on the surface of the steel coil. In severe cases, it can even damage subsequent rolling mill rolls and dies, significantly affecting their service life and substantially increasing production costs.

[0004] In existing technologies, a cleaning process is usually set up specifically for the workpiece surface after descaling. However, the cleaning effect of the surface after metal descaling is poor and the efficiency is low, which will affect the subsequent processing quality and production efficiency of the metal material. Utility Model Content

[0005] This invention aims to address one of the technical problems in related technologies to a certain extent. To this end, this invention provides a cleaning system and a descaling system, which have the advantage of high cleaning efficiency.

[0006] To achieve the above objectives, a first aspect of this utility model discloses a cleaning system for cleaning the surface of metal after descaling. The cleaning system includes a liquid storage component and a rinsing component. The rinsing component includes a first rinsing unit and a second rinsing unit arranged at a distance from each other. The gap between the first rinsing unit and the second rinsing unit is used to arrange a conveying unit, and the conveying surface of the conveying unit passes through the gap. The liquid inlet of the first rinsing unit and the liquid inlet of the second rinsing unit are connected to the output end of the liquid storage component. The first spray port of the first rinsing unit and the second spray port of the second rinsing unit are respectively oriented towards the conveying surface of the conveying unit.

[0007] The cleaning system in this technical solution can clean two opposite surfaces of the workpiece simultaneously, improving cleaning efficiency and quality, avoiding the problem of impurities contaminating other surfaces that need cleaning when cleaning only one surface at a time; it can also reduce the overall footprint of the equipment.

[0008] Furthermore, the orientation of the first and second spray nozzles forms an angle θ with the corresponding surface of the workpiece to be cleaned, and the angle θ satisfies the following requirement: 15°≤θ≤45°.

[0009] Furthermore, the rinsing component includes a protective cover and a mounting bracket. The first rinsing unit and the second rinsing unit are disposed inside the protective cover. The protective cover has an inlet and an outlet, which are used to house the conveying unit. The conveying surface of the conveying unit passes through the inlet and outlet. The mounting bracket has a first connecting portion and two spaced-apart second connecting portions. The mounting bracket is fixedly connected to the protective cover via the first connecting portion. The first rinsing unit and the second rinsing unit are respectively connected to the mounting bracket via the second connecting portions. This allows the rinsing operation to be carried out in a closed space, avoiding the impact of cleaning fluid splashing on the production environment and equipment.

[0010] Furthermore, at least one of the first rinsing unit and the second rinsing unit is rotatably connected to the mounting bracket via the second connecting part to adjust the angle between the spray nozzles of the first rinsing unit and the second rinsing unit and the conveying surface of the conveying unit.

[0011] Furthermore, the first flushing unit includes a first flushing pipe and a plurality of first nozzles, the plurality of first nozzles being arranged at intervals along the fluid flow direction of the first flushing pipe, and the first spray nozzles forming the first spray ports;

[0012] The second flushing unit includes a second flushing pipe and a plurality of second nozzles. The plurality of second nozzles are arranged at intervals along the fluid flow direction of the second flushing pipe, and the second spray nozzles form the second spray ports.

[0013] Furthermore, the liquid storage component includes a collection tank and a filter device. The collection tank is located at the bottom of the first rinsing unit and the second rinsing unit. The output end of the collection tank is connected to the input end of the filter device, which is used to filter the waste liquid after cleaning.

[0014] Furthermore, the filtration device includes a liquid storage container, and a primary filtration assembly, a secondary filtration assembly, a tertiary filtration assembly, a clear water tank, and a pressure pump assembly arranged sequentially within the liquid storage container. The cleaning fluid enters the clear water tank after passing through the primary, secondary, and tertiary filtration assemblies in sequence. The inlet of the liquid storage container is connected to the output end of the collection tank, the inlet of the pressure pump assembly is connected to the output end of the clear water tank, and the output end is connected to the inlet of the first rinsing unit and the inlet of the second rinsing unit, respectively, and is used to pressurize and output the cleaning fluid.

[0015] Furthermore, the primary filtration assembly includes a sedimentation tank for overflow filtration, the secondary filtration assembly includes at least one of a filter bag and a filter screen, and the tertiary filtration assembly includes a magnetic separator that separates magnetic substances from the cleaning fluid through magnetic adsorption.

[0016] By setting up multiple stages of filtration with different functions and principles, the filtration effect of the cleaning fluid can be improved, ensuring the quality of the cleaning fluid, greatly extending the service life of the spray pipe and nozzle, and reducing maintenance time.

[0017] Furthermore, the pressure pump assembly includes a plunger pump and a motor. The output end of the motor is connected to the plunger of the plunger pump and drives the plunger to reciprocate. The motor can adjust the movement frequency of the plunger to adjust the cleaning pressure.

[0018] The second aspect of this utility model discloses a descaling system, including a conveying unit and a cleaning system. The conveying unit is used to convey workpieces to be cleaned. The cleaning system includes the cleaning system of the first aspect. The first rinsing unit and the second rinsing unit are respectively disposed on the top side and the bottom side of the conveying unit. The conveying unit includes a plurality of rollers arranged at intervals. One of the first rinsing unit and the second rinsing unit located on the bottom side of the conveying unit is disposed within the interval between the rollers.

[0019] The descaling system provided by this utility model has a similar deductive reasoning process to the aforementioned cleaning system, and will not be repeated here.

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0035] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in one embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0036] In related technologies, descaling systems typically utilize multiple nozzles to rinse the workpiece surface, sometimes supplemented by brushes. However, this method is uneconomical due to its high investment and large footprint; furthermore, the brushes are prone to shedding bristles, failing to meet product requirements.

[0037] See appendix Figure 1One embodiment of this utility model discloses a cleaning system for cleaning the surface of metal after descaling. The cleaning system includes a liquid storage component 20 and a rinsing component 10. The rinsing component 10 includes a first rinsing unit 11 and a second rinsing unit 12 arranged at a distance from each other. The gap between the first rinsing unit 11 and the second rinsing unit 12 is used to set up a conveying unit, and the conveying surface of the conveying unit passes through the gap. The liquid inlet of the first rinsing unit 11 and the liquid inlet of the second rinsing unit 12 are connected to the output end of the liquid storage component 20. The first spray port of the first rinsing unit 11 and the second spray port of the second rinsing unit 12 are respectively facing the conveying surface of the conveying unit (that is, the first spray port of the first rinsing unit 11 and the second spray port of the second rinsing unit 12 are respectively facing the top surface and the bottom surface of the workpiece) to simultaneously clean the top surface and the bottom surface of the workpiece 40 to be cleaned.

[0038] The cleaning system in this embodiment is generally used in physical descaling systems. It is installed after sandblasting descaling. During sandblasting descaling, steel grit and oxide scale remain on the surface of the workpiece 40 (usually a steel plate or coil). If the surface is not thoroughly rinsed, residual steel grit particles, iron filings, or sludge can cause scratches, pits, or pitting on the steel coil surface. These additional defects can also damage subsequent rolling mill rolls and dies, significantly affecting their service life and substantially increasing production costs.

[0039] Of course, in actual use, the cleaning system in this embodiment can also be applied to other scenarios that require cleaning.

[0040] In this embodiment, the cleaning system cleans the surface of the workpiece 40 by liquid rinsing. Compared with the structure in related technologies that uses a brush to clean the surface of the workpiece 40, liquid rinsing can reduce damage to the surface of the workpiece 40. The cleaning fluid in this embodiment is generally water.

[0041] The conveying unit is used to transport the workpiece 40 to be cleaned, so that the workpiece can pass through the gap between the first rinsing unit 11 and the second rinsing unit 12 along with the conveying unit.

[0042] In actual setup, the conveying unit can be configured in different forms as needed, such as roller conveyor, chain conveyor or synchronous belt conveyor.

[0043] The liquid storage component 20 in this embodiment generally includes a container for storing cleaning fluid, which serves as the source of the cleaning fluid and provides clean cleaning fluid to the first rinsing unit 11 and the second rinsing unit 12 to ensure cleaning quality.

[0044] The rinsing component 10 in this embodiment includes a first rinsing unit 11 and a second rinsing unit 12. The main difference between the first rinsing unit 11 and the second rinsing unit 12 lies in their placement during use. One of the first rinsing unit 11 and the second rinsing unit 12 is placed on the top side of the workpiece 40 to be cleaned, and the other is placed on the bottom side of the workpiece 40 to be cleaned, and can simultaneously clean the top and bottom surfaces of the workpiece 40 to be cleaned.

[0045] Compared to the cleaning method in related technologies that only sets a rinsing structure on the top side of the workpiece 40, the cleaning system in this embodiment cleans the workpiece 40 more thoroughly and can avoid the problem that impurities will be carried to the other surface by the water flow during the rinsing process due to only having a single-sided cleaning structure. In addition, compared to some structures that require flipping over to clean the other surface, the cleaning system in this embodiment is more efficient and can reduce the size of the equipment.

[0046] In this embodiment, a first spray nozzle is formed on the first rinsing unit 11, and a second spray nozzle is formed on the second rinsing unit 12. Cleaning liquid is sprayed onto the corresponding surface of the workpiece 40 to be cleaned through the first and second spray nozzles, respectively. The cleaning liquid itself exerts its own pressure to clean the surface of the workpiece 40. In a specific setting, the pressure of the first and second spray nozzles is between 20 bar and 100 bar.

[0047] In one embodiment of this utility model, the orientation of the first and second injection ports forms an angle θ with the conveying surface of the conveying unit, and the angle θ satisfies the following requirement: 15°≤θ≤45°.

[0048] See appendix Figure 2 In this embodiment, by setting the included angle θ, the cleaning fluid cannot be sprayed vertically onto the workpiece surface, which can reduce irregular splashing of waste fluid and improve cleaning quality.

[0049] In actual setup, the movement direction of the workpiece 40 to be cleaned in this embodiment is from left to right, while the first spray port and the second spray port are both facing to the left. In this way, during the cleaning process, the spray direction of the liquid is opposite to the conveying direction of the conveying unit (that is, the movement direction of the workpiece 40). Thus, during the actual cleaning process, the cleaning liquid is less likely to cross the setting positions of the first rinsing unit 11 and the second rinsing unit 12. It is equivalent to the first rinsing unit 11 and the second rinsing unit 12 forming a barrier zone for the cleaning liquid, reducing the impact of impurities and waste liquid during the cleaning process on the subsequent processes of the workpiece 40.

[0050] In this embodiment, the angle between the orientation of the first and second spray nozzles and the surface of the corresponding workpiece 40 to be cleaned can be set to be the same or different, depending on the actual needs.

[0051] As one embodiment of this utility model, see the appendix. Figure 1 The rinsing component 10 includes a protective cover 13 and a mounting bracket 14. The first rinsing unit 11 and the second rinsing unit 12 are disposed inside the protective cover 13. The protective cover 13 has an inlet 131 and an outlet 132. The inlet 131 and the outlet 132 are used to house the conveying unit. The conveying surface of the conveying unit passes through the inlet 131 and the outlet 132. The mounting bracket 14 has a first connecting portion and two spaced-apart second connecting portions. The mounting bracket 14 is fixedly connected to the protective cover 13 through the first connecting portion. The first rinsing unit 11 and the second rinsing unit 12 are respectively connected to the mounting bracket 14 through the second connecting portions.

[0052] The rinsing component 10 in this embodiment includes a protective cover 13. In actual installation, the protective cover 13 is used to form a closed space, so that the rinsing operation is carried out in the closed space. This can reduce the impact of the splashing of cleaning fluid on the production environment and equipment during the rinsing process and improve the protection effect.

[0053] In actual installation, the protective cover 13 can be made of transparent material, so that the workers can observe the cleaning process inside from the outside of the protective cover 13.

[0054] In this embodiment, the first rinsing unit 11 and the second rinsing unit 12 are fixed by the mounting bracket 14. In actual installation, this can improve the stability of the installation of the first rinsing unit 11 and the second rinsing unit 12 and maintain the distance between them.

[0055] In one embodiment of the present invention, at least one of the first rinsing unit 11 and the second rinsing unit 12 is rotatably connected to the mounting bracket 14 through the second connecting part, so as to adjust the angle between the spray nozzle of the corresponding first rinsing unit 11 and the second rinsing unit 12 and the surface of the workpiece 40 to be cleaned.

[0056] Since the thickness of the workpiece 40 is uncertain during actual operation, when the thickness of the workpiece 40 changes, the spray nozzles of the first rinsing unit 11 and the second rinsing unit 12 may be too close or too far apart. By adjusting the angle, the distance between the spray nozzles of the first rinsing unit 11 and the second rinsing unit 12 and the surface of the workpiece 40 can be finely adjusted, thereby improving safety and cleaning quality.

[0057] As one embodiment of this utility model, see the appendix. Figure 1The first flushing unit 11 includes a first flushing pipe 111 and a plurality of first nozzles 112. The plurality of first nozzles 112 are arranged at intervals along the fluid flow direction of the first flushing pipe 111, and the first spray port is formed on the first nozzle 112.

[0058] The second flushing unit 12 includes a second flushing pipe 121 and a plurality of second nozzles 122. The plurality of second nozzles 122 are arranged at intervals along the fluid flow direction of the second flushing pipe 121, and the second spray nozzles are formed on the second nozzles 122.

[0059] In this embodiment, both the first rinsing unit 11 and the second rinsing unit 12 are equipped with multiple nozzles. In actual installation, the nozzles are arranged along the width direction of the workpiece 40. Generally, the width covered by the nozzles is not less than the width of the workpiece 40. This ensures that the spray range can completely cover the surface of the workpiece 40 and avoids the problem of missed cleaning.

[0060] In actual setup, to ensure better rinsing effect, the first rinsing unit 11 and the second rinsing unit 12 are respectively configured to move along the width direction of the workpiece 40 (the direction orthogonal to the conveying direction of the workpiece 40), which can avoid the problem that some parts may not be rinsed due to the gap between the nozzles.

[0061] As one embodiment of this utility model, see the appendix. Figure 3 The liquid storage component 20 includes a liquid collection tank 21 and a filter device 22. The liquid collection tank 21 is located at the bottom of the first rinsing unit 11 and the second rinsing unit 12. The output end of the liquid collection tank 21 is connected to the input end of the filter device 22. The filter device 22 is used to filter the waste liquid after cleaning.

[0062] In this embodiment, the collection tank 21 is used to recover the cleaning fluid after rinsing the workpiece 40, so as to realize the recycling of the cleaning fluid. The filter device 22 is used to filter the cleaning fluid, filter out impurities, and ensure the water quality of the cleaning.

[0063] This embodiment does not specifically limit the structure of the filter device 22. In actual installation, the filter device 22 can be a single filtration method or a combination of multiple different filtration methods, as long as it can completely filter the impurities in the cleaning fluid.

[0064] As one embodiment of this utility model, see the appendix. Figure 3The filtration device 22 includes a liquid storage container 221, and a primary filtration assembly 222, a secondary filtration assembly 223, a tertiary filtration assembly 224, a clear water tank 226, and a pressure pump assembly 225 arranged sequentially within the liquid storage container 221. The cleaning fluid enters the clear water tank 226 after passing through the primary filtration assembly 222, the secondary filtration assembly 223, and the tertiary filtration assembly 224 in sequence. The inlet of the liquid storage container 221 is connected to the output end of the collection tank 21, and the inlet of the pressure pump assembly 225 is connected to the output end of the clear water tank 226. The output end is connected to the inlet of the first rinsing unit 11 and the inlet of the second rinsing unit 12, respectively, and is used to pressurize and output the cleaning fluid.

[0065] The filtration device 22 in this embodiment includes three filtration components, which means that when in use, it can achieve a triple filtration effect on the cleaning solution and improve water quality.

[0066] The primary filter component 222, the secondary filter component 223, and the tertiary filter component 224 can use the same filtration method to achieve multiple filtrations, or they can be set to different filtration methods to achieve more targeted filtration.

[0067] In a specific configuration, the primary filtration component 222 includes a sedimentation tank for overflow filtration, the secondary filtration component 223 includes at least one of a filter bag and a filter screen, and the tertiary filtration component 224 includes a magnetic separator that separates magnetic substances from the cleaning fluid through magnetic adsorption.

[0068] In this embodiment, the primary filter assembly 222, secondary filter assembly 223, and tertiary filter assembly 224 are configured with different filtration methods. The primary filter assembly 222 uses overflow filtration, which, through sedimentation, removes larger impurities. The secondary filter assembly 223 employs a pore filtration principle, achieving a maximum filtration precision of 10μm. The tertiary filter assembly 224 uses a magnetic separator, separating magnetic substances from the cleaning fluid through magnetic adsorption; it can also adsorb even finer magnetic powders. This combination of three different filtration methods ensures the quality of the cleaning fluid, improves the cleaning effect, and reduces damage to the surface of the workpiece 40.

[0069] By setting up multiple stages of filtration with different functions and principles, the filtration effect of the cleaning fluid can be improved, ensuring the quality of the cleaning fluid, greatly extending the service life of the spray pipe and nozzle, and reducing maintenance time.

[0070] In one embodiment of this utility model, the pressure pump assembly 225 includes a plunger pump and a motor. The output end of the motor is connected to the plunger of the plunger pump and drives the reciprocating motion of the plunger. The motor can adjust the motion frequency of the plunger to adjust the cleaning pressure.

[0071] See appendix Figure 1 The second aspect of this utility model discloses a descaling system, including a roller conveying unit 30 and a cleaning system. The roller conveying unit 30 is used to convey a workpiece 40 to be cleaned. The cleaning system includes the cleaning system of the first aspect. The first rinsing unit 11 and the second rinsing unit 12 are respectively disposed on the top side and the bottom side of the roller conveying unit 30. The roller conveying unit 30 includes a plurality of rollers 30 arranged at intervals. One of the first rinsing unit 11 and the second rinsing unit 12 located on the bottom side of the roller conveying unit 30 is disposed within the interval of the rollers 30.

[0072] In actual use, the descaling system in this embodiment also includes a sandblasting descaling process, which is performed before the cleaning system.

[0073] In this embodiment, one of the first rinsing unit 11 and the second rinsing unit 12 is arranged within the gap between the rollers 30, which makes good use of the gap between the rollers 30, making the overall structure more compact. Moreover, the presence of the rollers 30 can also ensure that the workpiece 40 does not directly touch the rinsing unit, thus improving the safety effect.

[0074] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
