Description

Technical Field

[0001] The utility model relates to the impurity cleaning in the process of section steel sawing, in particular to a device for cleaning water stains on section steel. Background Art

[0002] In the rolling process of section steel, turbid circulating water is needed for cooling. Subsequently, the section steel is straightened through a spray cooling zone on the cooling bed, and cooling water also flows into the section steel groove during cold saw cutting. However, if the moisture in these cooling processes fails to be removed in time, especially when the water stains in the section steel groove remain on the section steel web for a long time, yellow rust will quickly form because the water contains a large amount of chloride ions, and chloride ion corrosion is one of the common metal corrosion phenomena.

[0003] Furthermore, carbon steel is particularly vulnerable to this environment because chloride ions can combine with the moisture on the surface of carbon steel to produce an acidic environment, damaging the original passivation protective layer on the surface of carbon steel, thus leading to the occurrence of electrochemical corrosion. Specifically, after chloride ions are adsorbed on the surface of carbon steel, they react with water molecules to generate hydrogen chloride, which then reacts with the passivation film on the surface of carbon steel to produce soluble iron ions and chlorides. This not only accelerates the corrosion of the steel surface but also reduces its durability and aesthetic appearance.

[0004] For the above reasons, after the section steel completes the sawing process - usually each section steel is cut into a standard size of 12 meters in length - and before it is ready to enter the subsequent stacking process, special attention must be paid to handling the possible residual moisture problem in the sawed section steel groove. If not taken seriously and the section steel with residual water stains is directly stacked, rust will occur on the section steel web and its flange parts. This situation not only damages the surface quality of the section steel but may also seriously affect the brand reputation of the product. Therefore, it is particularly important to take effective measures to reduce or eliminate the residual moisture in the section steel groove to prevent unnecessary rusting of the section steel before stacking and ensure the quality and market competitiveness of the final product. Summary of the Invention

[0005] The utility model aims at the defects existing in the prior art and provides a device for cleaning water stains on section steel. It aims at the difficulties in directly stacking the existing section steel after sawing, which affect the quality of the section steel, and provides a device that can clean the water stains after the section steel is sawed to address the corrosion of the section steel caused by the residual water stains in the section steel groove.

[0006] To achieve the above object, the utility model adopts the following technical solutions. A steel profile water stain cleaning device includes a cleaning device disposed between a feeding roller line and a discharging roller line. The cleaning device includes a material receiving trough at the bottom, which is used to collect water stains and impurities removed from the surface of the steel profile. On both sides of the material receiving trough, there are side plates for heightening: a left side plate and a right side plate, and the tops of both side plates are fixedly connected to a top cover.

[0007] Between the left side plate and the right side plate and above the material receiving trough, there are three pipelines: a vacuum pipeline, a high-pressure air pipeline, and a high-temperature gas pipeline; the three pipelines are arranged in sequence along the conveying direction of the steel profile. That is, the vacuum pipeline, the high-pressure air pipeline, and the high-temperature gas pipeline are arranged in sequence from the inlet direction to the outlet direction of the cleaning device.

[0008] At the bottom of the vacuum pipeline, there is a flexible hose connected thereto, and the lower end of the flexible hose can contact the surface of the steel profile to form a vacuum state to suck the water stains on the surface of the steel profile.

[0009] Below the high-pressure air pipeline, there is a metal nozzle connected thereto, and the metal nozzle is arranged facing the driving direction of the steel profile to blow away the water stains on the surface of the steel profile.

[0010] The high-temperature gas pipeline is connected to a row of high-temperature nozzles through high-temperature branch pipes, and the high-temperature nozzles spray high-temperature gas downward to dry the remaining water stains on the surface of the steel profile.

[0011] Further, there are at least 15 metal nozzles and at least 10 flexible hoses.

[0013] Furthermore, the branch pipes are respectively connected to the corresponding high-temperature branch pipes and high-temperature nozzles.

[0014] Further, a curtain is provided at each of the inlet and outlet of the cleaning device to prevent water stains from splashing outwards during the cleaning process.

[0015] Furthermore, the curtain is made of a soft material and is suspended on the top cover or the side plate. And it has sufficient flexibility so that it can automatically separate when the steel profile passes through.

[0016] Further, a discharge port cover plate is provided at the lower part of one side of the material receiving trough to facilitate the regular cleaning of impurities in the material receiving trough.

[0017] Further, the feeding roller line is used to convey the sawn steel profiles, and the discharging roller line is used to convey the cleaned steel profiles to the stacking process.

[0018] Further, the height of the material receiving tank is such that when the profiled steel is transported by the feeding roller line and passes above the material receiving tank, the top of the material receiving tank does not contact the bottom of the profiled steel. That is, during this process, the material receiving tank does not interfere with the profiled steel and does not hinder the passage of the profiled steel.

[0030] To make the objectives, technical solutions and beneficial effects of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0031] As Figures 1-4 shown, the water stain cleaning device 3 for the profiled steel 4 includes a cleaning device 3 disposed between the feeding roller line 1 and the discharging roller line 2; the feeding roller line 1 is used to convey the sawn profiled steel 4, and the discharging roller line 2 is used to convey the profiled steel 4 after cleaning to the stacking process. The cleaning device 3 includes a material receiving trough 301 at the bottom, and the material receiving trough 301 is used to collect the water stains and impurities removed from the surface of the profiled steel 4; on both sides of the material receiving trough 301, there is a side plate for heightening: the left side plate 304 and the right side plate 303, and the tops of both side plates are fixedly connected to a top cover 305.

[0032] Between the left side plate 304 and the right side plate 303, above the material receiving trough 301, there are three pipelines: a vacuum pipeline 307, a high-pressure air pipeline 308, and a high-temperature gas pipeline 309; the three pipelines are arranged in sequence along the conveying direction of the profiled steel 4. The vacuum pipeline 307, the high-pressure air pipeline 308, and the high-temperature gas pipeline 309 are parallel to each other, and one ends of the vacuum pipeline 307, the high-pressure air pipeline 308, and the high-temperature gas pipeline 309 are all fixed to the upper part of the left side plate 304, and the other ends of the three are all fixed to the upper part of the right side plate 303.

[0033] Among them, first, a hose 310 is provided at the bottom of the vacuum pipeline 307 and is connected to it. The lower end of the hose 310 can contact the surface of the profiled steel 4 and form a vacuum state to suck the water stains on the surface of the profiled steel 4.

[0034] At the entrance and exit of the cleaning device 3, there is a curtain 306 each, which is used to prevent water stains from splashing outwards during the cleaning process. The curtain 306 is made of a soft material, and the curtain 306 is suspended on the top cover 305 or the side plate. And it has sufficient flexibility so that it can automatically separate when the profiled steel 4 passes through. When the profiled steel 4 enters, the curtain 306 is pushed open. The profiled steel 4 first passes under the vacuum pipeline 307. The vacuum pipeline 307 is connected with a hose 310, and the lower end of the hose 310 can contact the surface of the profiled steel 4 and form a vacuum state to suck the water stains on the surface of the profiled steel 4.

[0035] Second, a metal nozzle 311 is provided under the high-pressure air pipeline 308 and is connected to it. The metal nozzle 311 is arranged towards the driving direction of the profiled steel 4 to blow away the water stains on the surface of the profiled steel 4. There are at least 15 metal nozzles 311. Then the profiled steel 4 passes under the high-pressure air pipeline 308, and the metal nozzles 311 spray high-pressure gas obliquely to the left front to blow away the water stains on the surface of the profiled steel 4 and guide part of them into the material receiving trough 301.

[0036] 3. The high-temperature gas pipeline 309 is connected with a row of high-temperature nozzles 313 through high-temperature branch pipes 312. The high-temperature nozzles 313 spray high-temperature gas downward to dry the water stains remaining on the surface of the section steel 4. There are at least 10 hoses 310. At least 8 vertical high-temperature branch pipes 312 are arranged at equal intervals at the bottom of the high-temperature gas pipeline 309. The bottom of each high-temperature branch pipe 312 is connected with a plurality of high-temperature nozzles 313 through a branch pipe perpendicular to it, and there are at least 7 high-temperature nozzles 313 on each branch pipe. The branch pipes are respectively connected with the corresponding high-temperature branch pipes 312 and high-temperature nozzles 313. The section steel 4 finally passes under the high-temperature gas pipeline 309, and the high-temperature nozzles 313 spray high-temperature gas downward to dry the water stains remaining on the surface of the section steel 4.

[0037] Preferably, a discharge port cover plate 302 is arranged at the lower part of one side of the material receiving tank 301, which is convenient for regularly cleaning the impurities in the material receiving tank 301. The height of the material receiving tank 301 is such that when the section steel 4 is transported by the feeding roller line 1 and passes above the material receiving tank 301, the top of the material receiving tank 301 does not contact the bottom of the section steel 4. That is, during this process, the material receiving tank 301 does not interfere with the section steel 4 and does not hinder the passage of the section steel 4.

[0038] The use process of the section steel water stain cleaning device is described in combination with the attached drawings and technical solutions:

[0039] 1. After the section steel 4 is cut to length at the front section of the feeding roller line 1, the cut section steel 4 is conveyed by the feeding roller line to the next process section for stacking.

[0040] 2. The sawing and the previous processes will spray water on the channel steel, resulting in a lot of remaining water stains on the surface and in the grooves of the section steel 4 after sawing.

[0041] 3. The present utility model adds a water stain cleaning device 3 between the sawing and stacking processes, which is installed between the two roller lines.

[0042] 4. When the section steel 4 is conveyed from the feeding roller line 1 into the cleaning device 3, the section steel 4 pushes open the curtain 306 at the front end of the cleaning device 3 and enters the cleaning device 3, and the cleaning device 3 starts to operate.

[0043] 5. The section steel 4 first passes under the vacuum pipeline 307. A row of hoses 310 are connected to the vacuum pipeline 307. The lower ends of the hoses 310 can droop to the height of the upper surface of the roller path. When the section steel 4 passes through, the lower ends of the hoses 310 contact the surface of the section steel 4. At this time, the inside of the hoses 310 is in a vacuum state, and a vacuum state will be formed at the contact surface between the lower ports of the hoses 310 and the section steel 4, so that the water stains on the surface of the section steel 4 will be sucked into the vacuum pipeline 307 through the lower ports of the hoses 310 and finally transported away through the vacuum pipeline 307.

[0044] 6. Next, the profiled bar 4 passes under the high-pressure gas pipeline 308. A row of metal nozzles 311 is connected to the high-pressure gas pipeline 308. The nozzle openings of the metal nozzles 311 are inclined 45° to the left front. When the profiled bar 4 passes through, the high-pressure gas ejected from the nozzles of the metal nozzles 311 contacts the surface of the profiled bar 4. The high-pressure gas drives the water stains on the surface of the profiled bar 4 to the left. Part of the water stains are blown into the material receiving trough 301 below the cleaning device 3 and accumulate. During the process of being intercepted by the high-pressure gas, the other part of the water stains is sucked into the vacuum pipeline 307 through the lower port of the hose 310 in the previous process.

[0045] 7. Then, the profiled bar 4 passes under the high-temperature gas pipeline 309. A row of high-temperature branch pipes 312 is connected to the high-temperature gas pipeline 309. A row of high-temperature nozzles 313 is further connected below each high-temperature branch pipe 312. The nozzle openings of the high-temperature nozzles 313 face downwards. When the profiled bar 4 passes through, the high-temperature gas ejected from the nozzles of the high-temperature nozzles 313 contacts the surface of the profiled bar 4. The high-temperature gas dries the water stains on the surface of the profiled bar 4 at high temperature and dries the remaining water stains on the surface of the profiled bar 4 at high temperature.

[0046] 8. Then, the profiled bar 4 passes through the cleaning device 3 through the curtain 306 at the outlet, completing the cleaning work of the water stains and entering the next stacking process.

[0047] 9. Curtains 306 (made of soft materials) are arranged on both sides of the cleaning device 3, which can prevent water stains from splashing outwards.

[0048] 10. An outlet cover plate 302 is arranged below the right side plate 303 of the cleaning device 3. The purpose is that when the impurities and water stains in the material receiving trough 301 remain to a certain extent, the operator can open the outlet cover plate 302 for cleaning.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that; they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; therefore, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope defined by the claims of the present invention.
