Description

Technical Field

[0001] The invention belongs to the technical field of cleaning pollution of layer cooling headers, in particular to a layer cooling header cleaning device. Background Art

[0002] Layer cooling is a key process for cooling the strip from the hot rolling exit temperature to the coiling temperature, and the uniformity of the layer cooling water directly affects the uniformity of the strip performance, and then affects the uniformity of the stress distribution in the strip, ensuring the performance and shape quality of the strip. In order to improve the uniformity of layer cooling, it is necessary to clean the layer cooling device regularly. The layer cooling device consists of a water tank, a water supply main pipe, a water supply branch pipe and evenly distributed water outlets. The water supply branch pipe and the water outlet are combined to form a layer cooling header, and the layer cooling header is divided into an upper layer cooling header and a lower layer cooling header. The inner wall of the outlet of the lower layer cooling header is prone to the adhesion of pollutants such as sludge, resulting in a decrease in the water output, causing the water outlet uniformity of the lower layer cooling header to deteriorate, which can easily lead to uneven cooling of the strip.

[0003] In the related art, commonly used cleaning methods are usually divided into two types. The first method is to disassemble the water supply main pipe and one end of the water supply branch pipe and clean them with a high-pressure water gun. Although this method can clean up pollutants such as sludge, the water supply branch pipe must be emptied, and the maintenance time is long, resulting in low production efficiency; the other method is to manually use welding rods, iron wires, etc. to poke off pollutants such as sludge attached to the inner walls of several water outlets of the layer cooling header one by one. This cleaning method can be carried out during a short-term maintenance, but the pollutants such as sludge that are directly poked off fall into the water supply branch pipe of the layer cooling header, and the fallen pollutants will be attached to the outlet pipe again during the process of water being sprayed out through the outlet pipe, and the purpose of effectively cleaning the layer cooling header cannot be achieved.

[0004] Therefore, there is an urgent need for a layer cooling header cleaning device that can facilitate the cleaning of pollutants attached to a number of water outlet pipes and prevent pollutants from falling into the water supply branch pipe to cause secondary pollution. Summary of the invention

[0005] The object of the present invention is to provide a layer cooling header cleaning device to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0006] Specifically, the present invention discloses a layer cooling header cleaning device, comprising:

[0007] A water supply branch pipe, with a plurality of water outlet pipes evenly arranged along the top of the water supply branch pipe;

[0008] It also includes a cleaning mechanism, wherein the cleaning mechanism is provided with a connecting rod, one end of the connecting rod is connected to the transmission component, and the other end of the connecting rod is provided with a cleaning rod;

[0009] The cleaning rod is provided with a cleaning brush;

[0010] The end of the cleaning rod away from the connecting rod can be opened or closed and is provided with a pollutant anti-falling mechanism.

[0011] The layer cooling header cleaning device according to the present invention has at least the following beneficial effects:

[0012] The layer cooling header cleaning device can effectively clean the oil sludge and other pollutants attached to the outlet pipe of the layer cooling header, prevent the outlet pipe from being blocked and causing a reduction in water output, ensure the uniformity of water output from the outlet pipe, and thus improve the uniformity and consistency of strip cooling; and in the process of cleaning pollutants, the pollutant anti-fall mechanism of the device can make the cleaned pollutants fall into the pollutant anti-fall mechanism, effectively preventing the pollutants from falling into the water supply branch pipe and causing secondary pollution; at the same time, it prevents the pollutants that fall into the water supply branch pipe from being attached to the pipe wall of the outlet pipe again when being sprayed out through the outlet pipe, effectively improving the cleaning quality and efficiency of the layer cooling header, meeting the requirements of the hot-rolled strip cooling process, and ensuring the quality of the strip.

[0013] As a further solution of the present invention: the diameter of the cleaning rod is smaller than the inner diameter of the water outlet pipe.

[0014] As a further solution of the present invention: the sum of the diameters of the cleaning rod and the cleaning brush is greater than or equal to the inner diameter of the water outlet pipe.

[0015] Since the diameter of the cleaning rod is smaller than the inner diameter of the water outlet pipe, it is convenient for the cleaning rod to extend into the water outlet pipe to clean the pollutants in the water outlet pipe. In order to achieve the cleaning effect, the sum of the diameters of the cleaning rod and the cleaning brush is greater than or equal to the inner diameter of the water outlet pipe, so that the cleaning brush can better contact the pipe wall of the water outlet pipe, and the cleaning device is driven to rotate at high speed through the transmission component. The high-speed rotating cleaning brush can quickly clean the pollutants such as sludge attached to the pipe wall of the water outlet pipe, effectively improving the cleaning quality and efficiency of the pipe wall of the water outlet pipe, and the cleaned pollutants fall into the pollutant anti-fall mechanism, preventing the pollutants from causing secondary pollution to the water source in the water supply branch pipe, ensuring the quality of the water source in the pipe, avoiding the pollutants from attaching to the pipe wall of the water outlet pipe again to cause blockage, and improving the uniformity of water spraying in the water outlet pipe, thereby improving the cooling uniformity and consistency of the strip.

[0016] As a further solution of the present invention: the length of the cleaning rod is greater than or equal to the length of the water outlet pipe.

[0017] Since the length of the cleaning rod is greater than or equal to the length of the water outlet pipe, the cleaning brush on the cleaning rod can fully cover the wall of the water outlet pipe, ensuring that the cleaning brush can contact every part of the wall of the water outlet pipe, thoroughly removing pollutants attached to the wall of the water outlet pipe, improving the smoothness and uniformity of water outlet from the water outlet pipe, thereby improving the cooling efficiency of the strip.

[0018] As a further solution of the present invention: the cleaning brush is a stainless steel wire, and the cleaning brush is spirally arranged along the length direction of the cleaning rod.

[0019] Since the cleaning brush is made of stainless steel wire, the cleaning brush is spirally arranged along the length direction of the cleaning rod. The cleaning brush made of stainless steel wire has good corrosion resistance and wear resistance, can maintain stable performance during long-term use, and extend the service life of the cleaning brush; and the spirally arranged cleaning brush can increase the contact area with the wall of the water outlet pipe, improve the ability to remove pollutants such as sludge, and at the same time, the spirally arranged cleaning brush can generate a certain rotational force during the cleaning process, further enhancing the cleaning effect of the water outlet pipe.

[0020] As a further solution of the present invention: the pollutant anti-falling mechanism is provided with a support column, and the pollutant anti-falling mechanism is connected to one end of the cleaning rod through the support column.

[0021] Since the pollutant anti-fall mechanism is provided with a support column, the pollutant anti-fall mechanism is connected to one end of the cleaning rod through the support column, which can effectively improve the stability of the pollutant anti-fall mechanism, and ensure that when the device rotates at high speed to clean pollutants on the wall of the water outlet pipe, the pollutant anti-fall mechanism will not loosen or fall off due to excessively fast rotation or vibration caused by rotation, thereby improving the stability and reliability of the pollutant anti-fall mechanism.

[0022] As a further solution of the present invention: the free end of the support column is provided with an inverted cone-shaped dust collecting disc which can be opened or closed.

[0023] As a further solution of the present invention: the pollutant anti-fall mechanism also includes a plurality of support bars and a support ring arranged in a support column, one end of a plurality of the support bars is connected to the inner wall of the dust collecting disc, and the other end of a plurality of the support bars is passed through the support column and connected to the support ring.

[0024] As a further solution of the present invention: a connecting wire is arranged on the top of the support ring, the connecting wire passes through and extends outside the connecting rod, and a pull ring is arranged at one end of the connecting wire.

[0025] Since the free end of the support column can be opened or closed, an inverted cone-shaped dust-collecting disc is provided; the pollutant falling prevention mechanism also includes a plurality of support bars and a support ring arranged in the support column, one end of the plurality of support bars is connected to the inner side wall of the dust-collecting disc, and the other end of the plurality of support bars is passed through the support column and connected to the support ring; a connecting wire is provided at the top of the support ring, the connecting wire is passed through and extends outside the connecting rod, and a pull ring is provided at one end of the connecting wire;

[0026] When the wall of the water outlet pipe starts to be cleaned, the device enters the water outlet pipe vertically, and the support ring falls to the bottom of the support column due to gravity. The support ring drives one end of several support bars to fall at the same time, and the support bars change from a vertical downward force to a horizontal force. The dust collecting disc is opened by the other ends of several support bars, and when the outer wall of the dust collecting disc contacts the wall of the water outlet pipe, the dust collecting disc is slightly compressed and can pass through the water outlet pipe smoothly. After the dust collecting disc passes through the wall of the water outlet pipe, the dust collecting disc is opened to the maximum area. At this time, an upward force is applied to the device, and the inner wall of the dust collecting disc can be completely covered at the bottom of the water outlet pipe, effectively absorbing the pollutants that have been cleaned and dropped, ensuring that pollutants will not fall into the water supply branch pipe to cause secondary pollution;

[0027] When the wall of the water outlet pipe is cleaned, a downward force is applied to the device to keep a certain distance between the dust collecting disc and the bottom of the water outlet pipe. At this time, the pull ring outside the connecting rod is pulled, and the pull ring causes the connecting line to drive the support ring to move upward, and drives one end of a plurality of support strips on the support ring to move upward, so that the other ends of the plurality of support strips drive the dust collecting disc to shrink inward. At this time, an upward force is applied to the device to remove the device from the water outlet pipe; the cleaning effect of the water outlet pipe is effectively improved, and the cleaned pollutants are prevented from falling into the water supply branch pipe; at the same time, when the device is taken out, the dust collecting disc shrinks inward to wrap the pollutants in the dust collecting disc, thereby preventing the device from colliding or rubbing with the wall of the water outlet pipe during the removal process, causing the pollutants to vibrate and fall into the water supply branch pipe, thereby ensuring the cleaning quality and efficiency of the water outlet pipe.

[0028] As a further solution of the present invention: the diameter of the dust collecting disc when opened is larger than the outer diameter of the water outlet pipe, and the diameter of the dust collecting disc when closed is smaller than the inner diameter of the water outlet pipe.

[0029] Since the diameter of the dust collecting disc when it is opened is larger than the outer diameter of the water outlet pipe, and the diameter of the dust collecting disc when it is closed is smaller than the inner diameter of the water outlet pipe, the dust collecting disc can completely cover the bottom of the water outlet pipe when it is opened, ensuring that pollutants removed from the wall of the water outlet pipe during the cleaning process will not fall into the water supply branch pipe, and when the dust collecting disc is closed, the device can be smoothly taken out through the water outlet pipe; and the pollutants can be wrapped in the dust collecting disc to prevent the pollutants from scattering or falling into the water supply branch pipe to cause secondary pollution, thereby effectively improving the cleaning quality and efficiency of the water outlet pipe.

[0030] As a further solution of the present invention: the dust collecting disc is a stainless steel metal sheet, and the thickness of the dust collecting disc is 1mm-3mm.

[0031] Since the dust collecting disc is a stainless steel metal sheet, the thickness of the dust collecting disc is 1mm-3mm, which not only ensures sufficient strength to support the shape of the dust collecting disc and bear the weight of pollutants, but also maintains a certain flexibility to facilitate the opening and closing of the dust collecting disc. It is also easy to clean and maintain, which is beneficial to the portability and operational flexibility of the entire cleaning device. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the technical solution of the present invention is further specifically described below by way of examples and in conjunction with the accompanying drawings. In the specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the overall inventive concept of the present invention and should not be construed as a limitation of the present invention.

[0039] In addition, in the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the disclosed embodiments. However, it is apparent that one or more embodiments may be implemented without these specific details. In other cases, known structures and devices are embodied in a schematic manner to simplify the accompanying drawings.

[0040] like Figure 1-3The embodiment of the present invention shown is a layer cooling manifold cleaning device, comprising: a water supply branch pipe 1, a plurality of water outlet pipes 2 are evenly arranged along the top of the water supply branch pipe 1; it also comprises a cleaning mechanism 3, the cleaning mechanism 3 is provided with a connecting rod 301, one end of the connecting rod 301 is connected to the transmission component, and the other end of the connecting rod 301 is provided with a cleaning rod 302; the cleaning rod 302 is provided with a cleaning brush 303; the cleaning rod 302 is provided with a pollutant anti-fall mechanism 4 at one end away from the connecting rod 301, which can be opened or closed.

[0041] Specifically, the layer cooling header cleaning device can effectively clean the pollutants such as sludge attached to the outlet pipe 2 of the layer cooling header, prevent the outlet pipe 2 from being blocked and causing a reduction in water output, ensure the uniformity of water output from the outlet pipe 2, and thus improve the uniformity and consistency of strip cooling; and in the process of cleaning pollutants, the pollutant anti-fall mechanism 4 of the device can make the cleaned pollutants fall into the pollutant anti-fall mechanism 4, effectively preventing the pollutants from falling into the water supply branch pipe 1 and causing secondary pollution; at the same time, it prevents the pollutants that fall into the water supply branch pipe 1 from being attached to the pipe wall of the outlet pipe 2 again when being sprayed out through the outlet pipe 2, effectively improving the cleaning quality and efficiency of the layer cooling header, meeting the requirements of the hot-rolled strip cooling process, and ensuring the quality of the strip.

[0042] Furthermore, the diameter of the cleaning rod 302 is smaller than the inner diameter of the water outlet pipe 2 ; the sum of the diameters of the cleaning rod 302 and the cleaning brush 303 is greater than or equal to the inner diameter of the water outlet pipe 2 .

[0043] Specifically, since the diameter of the cleaning rod 302 is smaller than the inner diameter of the water outlet pipe 2, it is convenient for the cleaning rod 302 to extend into the water outlet pipe 2 to clean the pollutants in the water outlet pipe 2; in order to achieve the cleaning effect, the sum of the diameters of the cleaning rod 302 and the cleaning brush 303 is greater than or equal to the inner diameter of the water outlet pipe 2, so that the cleaning brush 303 can better contact the pipe wall of the water outlet pipe 2, and the cleaning device is driven to rotate at high speed through the transmission component. The high-speed rotating cleaning brush 303 can quickly clean the pollutants such as sludge attached to the pipe wall of the water outlet pipe 2, effectively improving the cleaning quality and efficiency of the pipe wall of the water outlet pipe 2, and the cleaned pollutants fall into the pollutant anti-fall mechanism 4, preventing the pollutants from causing secondary pollution to the water source in the water supply branch pipe 1, ensuring the quality of the water source in the pipe, avoiding the pollutants from attaching to the pipe wall of the water outlet pipe 2 again to cause blockage, and improving the uniformity of water spraying in the water outlet pipe 2, thereby improving the cooling uniformity and consistency of the strip.

[0044] According to the embodiment of the present invention, the length of the cleaning rod 302 is greater than or equal to the length of the water outlet pipe 2 .

[0045] Specifically, since the length of the cleaning rod 302 is greater than or equal to the length of the water outlet pipe 2, the cleaning brush 303 on the cleaning rod 302 can fully cover the wall of the water outlet pipe 2, ensuring that the cleaning brush 303 can contact every part of the wall of the water outlet pipe 2, thoroughly removing pollutants attached to the wall of the water outlet pipe 2, improving the smoothness and uniformity of water outlet from the water outlet pipe 2, thereby improving the cooling efficiency of the strip.

[0046] like Figure 2 As shown, the cleaning brush 303 is a stainless steel wire, and the cleaning brush 303 is spirally arranged along the length direction of the cleaning rod 302 .

[0047] Specifically, since the cleaning brush 303 is made of stainless steel wire, the cleaning brush 303 is spirally arranged along the length direction of the cleaning rod 302. The cleaning brush 303 made of stainless steel wire has good corrosion resistance and wear resistance, and can maintain stable performance during long-term use, thereby extending the service life of the cleaning brush 303; and the spirally arranged cleaning brush 303 can increase the contact area with the wall of the water outlet pipe 2, thereby improving the ability to remove pollutants such as sludge. At the same time, the spirally arranged cleaning brush 303 can generate a certain rotational force during the cleaning process, thereby further enhancing the cleaning effect of the water outlet pipe 2.

[0048] like Figure 3 As shown, the pollutant prevention mechanism 4 is provided with a support column 401 , and the pollutant prevention mechanism 4 is connected to one end of the cleaning rod 302 via the support column 401 .

[0049] Specifically, since the pollutant anti-fall mechanism 4 is provided with a support column 401, the pollutant anti-fall mechanism 4 is connected to one end of the cleaning rod 302 through the support column 401, which can effectively improve the stability of the pollutant anti-fall mechanism 4, and ensure that when the device rotates at high speed to clean the pollutants on the wall of the water outlet pipe 2, the pollutant anti-fall mechanism 4 will not loosen or fall off due to excessively fast rotation or vibration caused by rotation, thereby improving the stability and reliability of the pollutant anti-fall mechanism 4.

[0050] Furthermore, if Figure 3 As shown, the free end of the support column 401 can be opened or closed and is provided with an inverted cone-shaped dust collecting disc 402; the pollutant anti-fall mechanism 4 also includes a plurality of support bars 403 and a support ring 404 arranged in the support column 401, one end of the plurality of support bars 403 is connected to the inner wall of the dust collecting disc 402, and the other end of the plurality of support bars 403 is passed through the support column 401 and connected to the support ring 404; a connecting line 405 is provided on the top of the support ring 404, the connecting line 405 is passed through and extends to the outside of the connecting rod 301, and a pull ring 406 is provided at one end of the connecting line 405.

[0051] Specifically, since the free end of the support column 401 can be opened or closed, an inverted cone-shaped dust collecting disc 402 is provided; the pollutant falling prevention mechanism 4 also includes a plurality of support bars 403 and a support ring 404 arranged in the support column 401, one end of the plurality of support bars 403 is connected to the inner side wall of the dust collecting disc 402, and the other end of the plurality of support bars 403 is passed through the support column 401 and connected to the support ring 404; a connecting line 405 is provided at the top of the support ring 404, the connecting line 405 is passed through and extends to the outside of the connecting rod 301, and a pull ring 406 is provided at one end of the connecting line 405;

[0052] When the wall of the water outlet pipe 2 begins to be cleaned, the device vertically enters the water outlet pipe 2, and the support ring 404 falls to the bottom of the support column 401 due to gravity. The support ring 404 drives one end of the plurality of support bars 403 to fall at the same time, and the support bars 403 change the vertical downward force into a horizontal force, and the dust collecting disc 402 is opened by the other end of the plurality of support bars 403. When the outer wall of the dust collecting disc 402 contacts the wall of the water outlet pipe 2, the dust collecting disc 402 is slightly compressed and can pass through the water outlet pipe 2 smoothly. After the dust collecting disc 402 passes through the wall of the water outlet pipe 2, the dust collecting disc 402 is opened to the maximum area. At this time, an upward force is applied to the device, and the inner wall of the dust collecting disc 402 can be completely covered at the bottom of the water outlet pipe 2, effectively absorbing the pollutants that have been cleaned and dropped, ensuring that pollutants will not fall into the water supply branch pipe 1 to cause secondary pollution.

[0053] When the wall of the water outlet pipe 2 is cleaned, a downward force is applied to the device to keep the dust collecting disc 402 at a certain distance from the bottom of the water outlet pipe 2. At this time, the pull ring 406 outside the connecting rod 301 is pulled, and the pull ring 406 causes the connecting line 405 to drive the support ring 404 to move upward, and drives one end of the plurality of support strips 403 on the support ring 404 to move upward, so that the other ends of the plurality of support strips 403 drive the dust collecting disc 402 to shrink inwardly. At this time, an upward force is applied to the device to remove the device from the water outlet pipe 2; the cleaning effect of the water outlet pipe 2 is effectively improved, and the cleaned pollutants are prevented from falling into the water supply branch pipe; at the same time, when the device is taken out, the dust collecting disc 402 shrinks inwardly to wrap the pollutants in the dust collecting disc 402, so as to prevent the device from colliding or rubbing with the wall of the water outlet pipe 2 during the removal process, causing the pollutants to vibrate and fall into the water supply branch pipe 1, thereby ensuring the cleaning quality and efficiency of the water outlet pipe 2.

[0054] Furthermore, the diameter of the dust collecting disc 402 when opened is larger than the outer diameter of the water outlet pipe 2 , and the diameter of the dust collecting disc 402 when closed is smaller than the inner diameter of the water outlet pipe 2 .

[0055] Specifically, since the diameter of the dust collecting disc 402 when opened is larger than the outer diameter of the water outlet pipe 2, and the diameter of the dust collecting disc 402 when closed is smaller than the inner diameter of the water outlet pipe 2, the dust collecting disc 402 can completely cover the bottom of the water outlet pipe 2 when opened, ensuring that the pollutants removed from the wall of the water outlet pipe 2 during the cleaning process will not fall into the water supply branch pipe 1, and when the dust collecting disc 402 is closed, the device can be smoothly taken out through the water outlet pipe 2; and the pollutants can be wrapped in the dust collecting disc 402 to prevent the pollutants from scattering or falling into the water supply branch pipe 1 to cause secondary pollution, thereby effectively improving the cleaning quality and efficiency of the water outlet pipe 2.

[0056] It should also be noted that the dust collecting disc 402 is a stainless steel metal sheet, and the thickness of the dust collecting disc 402 is 1 mm-3 mm.

[0057] Specifically, since the dust collecting disc 402 is a stainless steel metal sheet, the thickness of the dust collecting disc 402 is 1mm-3mm, which not only ensures sufficient strength to support the shape of the dust collecting disc 402 and bear the weight of the pollutants, but also maintains a certain flexibility to facilitate the opening and closing of the dust collecting disc 402. At the same time, it is easy to clean and maintain, which is beneficial to the portability and operational flexibility of the entire cleaning device.

[0058] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
