Description

Technical Field

[0001] This application relates to the field of strip steel processing technology, specifically a strip steel surface active cleaning agent spraying device. Background Technology

[0002] During the production and processing of strip steel, contaminants such as rolling oil stains, oxide scale, metal shavings, and impurities in the grooves and depressions are easily left on its surface. If these are not thoroughly removed, they will directly affect the quality of subsequent rolling, plating, and coating processes, leading to problems such as insufficient coating adhesion and coating peeling.

[0003] Chinese utility model patent CN215328384U discloses an automatic spray cleaning system for steel strip reversing. It utilizes nozzles vertically connected to upper and lower spray pipes within the pickling tank, controlled by specific solenoid valves and main control panel buttons, enabling convenient start / stop of the spray water and saving on demineralized water. However, the upper and lower spray pipes are mostly arranged facing each other, leading to overlapping or gaps in the spray range. This results in cleaning blind spots on the edges of the steel strip and in the grooves on both sides, making it difficult to thoroughly remove contaminants. Furthermore, the nozzles often employ a fixed vertical spray design, meaning the cleaning agent can only act on the steel strip surface vertically. For contaminants deep within the grooves and at the roots of burrs, the vertical water flow is blocked by the recessed sidewalls and burrs, hindering effective impact and contact of the cleaning agent, thus reducing cleaning efficiency and effectiveness.

[0004] Therefore, this application provides a strip steel surface active cleaning agent spraying device to solve the above problems. Utility Model Content

[0005] This application provides a strip steel surface active cleaning agent spraying device, which aims to solve the problems mentioned in the background art. Existing spray cleaning systems are prone to forming cleaning blind spots due to the direct distribution of the upper and lower spray pipes, making it difficult to remove contaminants from the edges and grooves of the strip steel. Furthermore, the fixed vertical spray nozzles make it difficult to reach the depths of the grooves and the roots of burrs, resulting in poor cleaning efficiency and effect.

[0006] To achieve the above objectives, this application provides the following technical solution: a strip steel surface active cleaning agent spraying device, comprising a cleaning tank, a conveying mechanism disposed on the cleaning tank for conveying strip steel, a plurality of horizontal pipes respectively disposed at the top and bottom of the cleaning tank, nozzles fixedly disposed on the horizontal pipes and linearly distributed, and a conveying mechanism disposed on the cleaning tank for conveying active cleaning agent to the horizontal pipes and nozzles.

[0007] The spraying equipment also includes an adjustment mechanism disposed on the horizontal pipe and the conveying mechanism for adjusting the tilt angle of the spray nozzles on the horizontal pipe;

[0008] Multiple horizontal pipes located at the top and bottom of the cleaning tank are staggered. This staggered distribution of the horizontal pipes at the top and bottom of the cleaning tank allows the spray range of the upper and lower horizontal pipes to complement each other, reducing cleaning blind spots on both sides of the strip, as well as its edges and textures. This ensures that the active cleaning agent can fully act on both sides of the strip, as well as its edges and textures, improving the thoroughness of the strip surface cleaning. At the same time, by setting an adjustment mechanism, the tilt angle of the spray nozzles can be flexibly adjusted, allowing the cleaning agent water flow to impact the grooves and roots of burrs. This not only further ensures that the surface active cleaning agent fully contacts the contaminants, improving the decontamination efficiency, but also adapts to the cleaning of strips of different specifications.

[0009] Preferably, to achieve separate storage of cleaning wastewater and active cleaning agent, a fixed box is fixedly installed at the bottom of the cleaning tank. The fixed box contains a wastewater tank for collecting cleaning wastewater and an active cleaning agent tank for storing active cleaning agent. A drain pipe is fixedly installed at the bottom of the cleaning tank to discharge the cleaning wastewater into the wastewater tank. The drain pipe is connected to the wastewater tank. By directly discharging the wastewater from the cleaning tank into the wastewater tank through the drain pipe and storing the active cleaning agent in the active cleaning agent tank, the mixing of wastewater and active cleaning agent can be avoided, thereby facilitating the separate treatment of wastewater and active cleaning agent in the subsequent process and reducing treatment costs.

[0010] Preferably, to facilitate the discharge of wastewater from the wastewater tank and deteriorated or residual cleaning agent from the active cleaning agent tank, a waste discharge pipe is fixedly installed on one side of both the wastewater tank and the active cleaning agent tank, and a valve is fixedly installed on the waste discharge pipe. When the wastewater in the wastewater tank reaches a certain amount, or when the cleaning agent in the active cleaning agent tank deteriorates and needs to be replaced, simply open the valve on the waste discharge pipe, and the wastewater or waste cleaning agent can be discharged through the waste discharge pipe. Closing the valve stops the waste discharge, realizing waste discharge on demand, thereby improving the convenience of equipment maintenance.

[0011] Preferably, to facilitate internal maintenance and repair of the equipment, the top of the cleaning tank is provided with an opening, and a cover plate is fastened to the cleaning tank at the position corresponding to the opening. When it is necessary to repair or replace components such as horizontal pipes and nozzles inside the cleaning tank, the cover plate fastened to the opening is opened, and the corresponding operation is carried out through the opening. When the equipment is running, the cover plate is fastened to close the opening, which can prevent the cleaning agent from splashing out of the cleaning tank due to spraying, and also prevent external dust and impurities from falling into the cleaning tank and contaminating the strip steel and cleaning agent, thus taking into account both the convenience of equipment maintenance and the sealing of operation.

[0012] Preferably, to achieve continuous entry and exit of strip steel into and out of the cleaning tank, the conveying mechanism includes an inlet roller symmetrically rotatably connected to the inlet end of the cleaning tank, an outlet roller symmetrically rotatably connected to the outlet end of the cleaning tank, gears respectively fixedly sleeved on one end of the two inlet rollers and one end of the two outlet rollers, two drive motors respectively fixedly installed at the inlet and outlet ends of the cleaning tank for driving one of the inlet rollers and one of the outlet rollers to rotate, and guide rollers symmetrically rotatably connected to the cleaning tank and linearly distributed. The guide rollers are located on the same horizontal plane as the inlet rollers and the outlet rollers, and the guide rollers are located between the top and bottom horizontal tubes inside the cleaning tank. The gears on the two inlet rollers and the two outlet rollers are all meshed with each other. By driving the inlet rollers and the outlet rollers to rotate through the drive motors, and by using the gear meshing to make the two inlet rollers and the two outlet rollers rotate synchronously, the clamping, entry, and exit of the strip steel can be realized. The guide rollers can assist in the conveying of the strip steel and keep it horizontal, thereby realizing continuous cleaning of the strip steel and improving production efficiency and cleaning quality stability.

[0013] Preferably, in order to deliver the active cleaning agent to the horizontal pipe and the nozzle, the delivery mechanism includes a fixed pipe fixedly installed in the cleaning tank, a suction pump fixedly installed on one side of the fixed box, an inlet pipe fixedly connected to one end of the suction pump and fixedly connected to the inside of the active cleaning agent tank, and an outlet pipe fixedly connected to the other end of the suction pump and fixedly connected to the fixed pipe. The horizontal pipe is rotatably connected to the fixed pipe. The suction pump generates suction and uses the inlet pipe to draw the active cleaning agent from the active cleaning agent tank, and then delivers it to the fixed pipe through the outlet pipe, and then into the horizontal pipe and the nozzle, which can ensure a stable supply of active cleaning agent and meet the cleaning requirements.

[0014] Preferably, to adjust the spray angle of the nozzle, the adjustment mechanism includes a protective box fixedly installed on the fixed pipe and covering the junction of the fixed pipe and the horizontal pipe; a worm gear fixedly sleeved on the horizontal pipe and located inside the protective box; a worm rotatably connected inside the protective box and meshing with one side of the worm gear; and an angle motor fixedly installed inside the protective box for driving the worm gear to rotate. The angle motor drives the worm gear to rotate, and the meshing of the worm gear with the worm wheel causes the worm gear to drive the horizontal pipe to rotate, thereby changing the nozzle angle. This allows the cleaning agent water flow to impact the grooves and burr roots of the strip steel, ensuring that the active cleaning agent fully contacts the contaminants, improving the decontamination efficiency, and adapting to the cleaning of strip steel of different specifications.

[0015] The strip steel surface active cleaning agent spraying equipment uses multiple horizontal pipes at the top and bottom of the cleaning tank in a staggered manner, which allows the spray range of the upper and lower horizontal pipes to complement each other, reducing cleaning blind spots on both sides of the strip steel, as well as the edges and textures, and ensuring that both sides of the strip steel, as well as the edges and textures, can be fully acted on by the active cleaning agent, thereby improving the thoroughness of the strip steel surface cleaning.

[0016] This strip steel surface active cleaning agent spraying equipment, through the setting of an adjustment mechanism, can flexibly adjust the tilt angle of the spray nozzle, so that the cleaning agent water flow can impact the grooves and burr roots, which not only further ensures that the surface active cleaning agent fully contacts the pollutants and improves the decontamination efficiency, but also can adapt to the cleaning of strip steel of different specifications.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] This embodiment provides a strip steel surface active cleaning agent spraying device, such as... Figures 1-7 As shown, the spraying equipment includes a cleaning tank 1, a conveying mechanism 2 installed on the cleaning tank 1 for conveying strip steel, multiple horizontal pipes 3 respectively installed at the top and bottom of the cleaning tank 1, nozzles 4 fixedly installed on the horizontal pipes 3 and linearly distributed, and a conveying mechanism 5 installed on the cleaning tank 1 for conveying active cleaning agent to the horizontal pipes 3 and nozzles 4; the spraying equipment also includes an adjusting mechanism 6 installed on the horizontal pipes 3 and conveying mechanism 5 for adjusting the tilt angle of the nozzles 4 on the horizontal pipes 3; the multiple horizontal pipes 3 located at the top and bottom of the cleaning tank 1 are staggered.

[0033] In use, the strip steel to be cleaned is first conveyed into the cleaning tank 1 by the conveying mechanism 2. The conveying mechanism 2 can drive the strip steel to enter the cleaning tank 1 smoothly and keep it on the preset conveying path, ensuring that the strip steel is in the spraying area between the top and bottom horizontal pipes 3 inside the cleaning tank 1. Then, the conveying mechanism 5 is activated to transfer the active cleaning agent from the storage position to the horizontal pipes 3 inside the cleaning tank 1. After being diverted by the horizontal pipes 3, the active cleaning agent is delivered to the nozzles 4 fixed on the horizontal pipes 3, and sprayed onto the surface of the strip steel by the nozzles 4 to achieve cleaning. During this process, the multiple horizontal pipes 3 at the top and bottom inside the cleaning tank 1 are staggered. The spray range of the upper and lower horizontal pipes 3 is complementary, which can fully cover both sides of the strip steel, as well as the edges and textures, reducing blind spots in cleaning. At the same time, if it is necessary to adapt to different specifications of strip steel or to strengthen the cleaning of specific textures, depressions, and burr roots on the strip steel surface, the tilt angle of the nozzles 4 on the horizontal pipes 3 can be adjusted by the adjustment mechanism 6 before cleaning to change the spray angle of the nozzles 4. This allows the cleaning agent water flow to accurately impact the areas on the strip steel surface that need to be cleaned, ensuring that the active cleaning agent fully contacts the contaminants and improves the cleaning effect. The cleaned strip steel will then be conveyed out of the cleaning tank 1 by the conveying mechanism 2.

[0034] To achieve separate storage of cleaning wastewater and active cleaning agent, a fixed box 11 is fixedly installed at the bottom of the cleaning tank 1. The fixed box 11 contains a wastewater tank 12 for collecting cleaning wastewater and an active cleaning agent tank 13 for storing active cleaning agent. A drain pipe 14 is fixedly installed at the bottom of the cleaning tank 1 to discharge the cleaning wastewater in the cleaning tank 1 into the wastewater tank 12. The drain pipe 14 is connected to the wastewater tank 12. The wastewater in the cleaning tank 1 can be directly discharged into the wastewater tank 12 through the drain pipe 14, and the active cleaning agent is stored in the active cleaning agent tank 13. This avoids the mixing of wastewater and active cleaning agent, which facilitates the separate treatment of wastewater and active cleaning agent in the future and reduces treatment costs.

[0035] In addition, to facilitate the discharge of wastewater from the wastewater tank 12 and deteriorated or residual cleaning agent from the active cleaning agent tank 13, a waste discharge pipe 15 is fixedly installed on one side of both the wastewater tank 12 and the active cleaning agent tank 13, and a valve is fixedly installed on the waste discharge pipe 15. When the wastewater in the wastewater tank 12 reaches a certain amount, or when the cleaning agent in the active cleaning agent tank 13 deteriorates and needs to be replaced, simply open the valve on the waste discharge pipe 15, and the wastewater or waste cleaning agent can be discharged through the waste discharge pipe 15. Closing the valve will stop the discharge, realizing on-demand discharge and thus improving the convenience of equipment maintenance.

[0036] Specifically, the conveying mechanism 2 includes an inlet roller 21 symmetrically rotatably connected to the inlet end of the cleaning tank 1, an outlet roller 22 symmetrically rotatably connected to the outlet end of the cleaning tank 1, gears 23 respectively fixedly sleeved on one end of the two inlet rollers 21 and one end of the two outlet rollers 22, two drive motors 24 respectively fixedly installed at the inlet end and the outlet end of the cleaning tank 1 for driving one of the inlet rollers 21 and one of the outlet rollers 22 to rotate, and guide rollers 25 symmetrically rotatably connected to the inside of the cleaning tank 1 and linearly distributed. The guide rollers 25 are located on the same horizontal plane as the inlet rollers 21 and the outlet rollers 22, and the guide rollers 25 are located between the top and bottom horizontal tubes 3 inside the cleaning tank 1. The gears 23 on the two inlet rollers 21 and the gears 23 on the two outlet rollers 22 are meshed with each other.

[0037] When the strip steel needs to be conveyed and cleaned, two drive motors 24 installed at the inlet and outlet of the cleaning tank 1 are started. The drive motor 24 at the inlet of the cleaning tank 1 drives an inlet roller 21 connected to it to rotate, and the drive motor 24 at the outlet of the cleaning tank 1 drives an outlet roller 22 connected to it to rotate. Since gears 23 are fixedly sleeved at one end of both inlet rollers 21 and the two gears 23 mesh with each other, when one inlet roller 21 rotates, it will drive the other inlet roller 21 to rotate synchronously in the opposite direction through the gear 23. Similarly, the two outlet rollers 22 will also rotate synchronously in the opposite direction with one of the outlet rollers 22 under the meshing action of the gears 23. Subsequently, the strip steel to be cleaned flows from the two inlet rollers 21 at the inlet of the cleaning tank 1. The strip enters through the two guide rollers 21, which rotate synchronously in opposite directions to achieve clamping and smooth introduction. After entering the cleaning tank 1, the strip will come into contact with the guide rollers 25, which are linearly distributed inside the cleaning tank 1. Since the guide rollers 25, the guide rollers 21, and the outlet rollers 22 are located on the same horizontal plane and between the top and bottom horizontal tubes 3 inside the cleaning tank 1, the guide rollers 25 can play a supporting role during the strip conveying process, preventing the strip from sagging and shifting, and ensuring that the strip always remains horizontal as it passes through the spray area between the upper and lower horizontal tubes 3. The cleaned strip will continue to be conveyed to the two outlet rollers 22 at the outlet end of the cleaning tank 1. The synchronous counter-rotation of the two outlet rollers 22 achieves clamping and smooth export of the strip.

[0038] Furthermore, the conveying mechanism 5 includes a fixed pipe 51 fixedly installed in the cleaning tank 1, a suction pump 52 fixedly installed on one side of the fixed box 11, an inlet pipe 53 fixedly connected to one end of the suction pump 52 and fixedly connected to the inside of the active cleaning agent tank 13, and an outlet pipe 54 fixedly connected to the other end of the suction pump 52 and fixedly connected to the fixed pipe 51. The horizontal pipe 3 is rotatably connected to the fixed pipe 51.

[0039] Before the strip steel is conveyed through the conveying mechanism 2, the suction pump 52 is started, and the suction pump 52 generates negative pressure suction. Then, this suction draws the active cleaning agent stored in the active cleaning agent tank 13 into the suction pump 52 through the inlet pipe 53, which is fixedly connected to one end of the suction pump 52 and to the inside of the active cleaning agent tank 13. Then, the suction pump 52 pressurizes the drawn active cleaning agent and delivers it to the fixed pipe 51 through the outlet pipe 54, which is fixedly connected to the other end of the pump and to the fixed pipe 51 in the cleaning tank 1. After receiving the active cleaning agent, the fixed pipe 51 distributes it to each horizontal pipe 3. Finally, the active cleaning agent in the horizontal pipe 3 is sprayed out through the nozzle 4 fixed on it, providing a stable source of active cleaning agent for the unconveyed strip steel cleaning.

[0040] Furthermore, the adjustment mechanism 6 includes a protective box 61 fixedly installed on the fixed pipe 51 and covering the junction of the fixed pipe 51 and the horizontal pipe 3, a worm wheel 62 fixedly sleeved on the horizontal pipe 3 and located inside the protective box 61, a worm 63 rotatably connected inside the protective box 61 and meshing with one side of the worm wheel 62, and an angle motor 64 fixedly installed inside the protective box 61 for driving the worm 63 to rotate.

[0041] When the tilt angle of the nozzle 4 needs to be adjusted, the angle motor 64 is started. The output shaft of the angle motor 64 drives the worm gear 63 connected to it to rotate synchronously inside the protective box 61. Since the worm gear 63 meshes with the worm wheel 62, which is fixedly sleeved on the horizontal tube 3 and also located inside the protective box 61, the rotation of the worm gear 63 will drive the worm wheel 62 to rotate through the meshing transmission. The worm wheel 62 is fixedly sleeved on the horizontal tube 3, and its rotation will directly drive the horizontal tube 3 to rotate synchronously, thereby causing the nozzle 4 fixed on the horizontal tube 3 to change its tilt angle to adapt to different specifications of steel strip cleaning. For cleaning needs or precise impact on the surface of the strip steel, including the grooves and burr roots, the protective box 61, which is fixedly installed on the fixed pipe 51 and covers the junction of the fixed pipe 51 and the horizontal pipe 3, can effectively isolate the active cleaning agent, sewage and external impurities in the cleaning tank 1 from entering the internal transmission components, and prevent the worm gear 62 and worm 63 from rusting, jamming and other problems. This ensures the stability of the transmission process of the adjustment mechanism 6 and the service life of the parts. At the same time, the rotational connection between the horizontal pipe 3 and the fixed pipe 51 will not affect the normal delivery of the active cleaning agent due to the rotation of the horizontal pipe 3.

[0042] It should be added that a mechanical seal is used between the horizontal tube 3 and the fixed tube 51, which does not affect the rotation or the transmission of the active cleaning agent. At the same time, a sensor for detecting the strip conveying angle is also fixedly installed on the horizontal tube 3. This sensor can capture the strip conveying angle in real time and transmit the signal to the control system. When the control system determines that the angle is mismatched, it can start the angle motor 64 to adjust the angle of the horizontal tube 3 and the nozzle 4 on it, so that the spraying angle of the nozzle 4 is precisely adjusted to 30-60°, so that the spraying direction matches the strip conveying angle and ensures the cleaning effect.

[0043] It is worth noting that, in order to facilitate internal maintenance and repair of the equipment, an opening 16 is provided on the top of the cleaning tank 1, and a cover plate 17 is fastened to the corresponding position of the opening 16. When it is necessary to repair or replace components such as the horizontal pipe 3 and the nozzle 4 inside the cleaning tank 1, the cover plate 17 fastened to the opening 16 is opened, and the corresponding operation is carried out through the opening 16. When the equipment is running, the cover plate 17 is fastened to close the opening 16, which can prevent the cleaning agent from splashing out of the cleaning tank 1 due to spraying, and also prevent external dust and impurities from falling into the cleaning tank 1 and contaminating the strip steel and cleaning agent, thus taking into account both the convenience of equipment maintenance and the sealing of operation.

[0044] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
