Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning silicon steel coating nozzles, in particular to an online cleaning tool for silicon steel coating nozzles. Background Art

[0002] The silicon steel coating nozzle is one of the most important steps in silicon steel coating. The coating liquid in the coating nozzle is evenly sprayed onto the surface of the strip through the nozzle, thus completing the silicon steel coating. However, during long-term use, impurities in the coating liquid will scale on the inner wall of the coating nozzle, causing the space for the nozzle hole to become smaller and smaller until the nozzle hole is blocked. This results in uneven coating at the coating nozzle spraying area, affecting product quality.

[0003] Existing online cleaning tools for silicon steel coating nozzles usually use thin iron wire and manually clear the pipe. After the pipe is cleared by the thin iron wire, the scale on the inner wall of the nozzle where the spray hole is blocked is pushed away, so that the spray hole in the nozzle can spray the coating liquid normally.

[0004] The existing online cleaning tools for silicon steel coated nozzles still have some shortcomings during actual use. The blocked nozzle holes are cleared by thin iron wire, so that the scale on the inner wall of the nozzle at the nozzle hole is cleaned, and the remaining scaled parts of the inner wall of the pipe cannot be effectively cleaned. After spraying for a period of time, the scale on the inner wall of the nozzle will fall off and still block the nozzle hole of the nozzle. At the same time, during the production process, when the nozzle is blocked, the staff on the production site need to use iron wire to clean the blocked nozzle on the production line. During this process, the staff need to be close to the running strip steel and equipment, which poses a major safety hazard.

[0005] To this end, the utility model provides an online cleaning tool for a silicon steel coating nozzle. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: the utility model describes an online cleaning tool for a silicon steel coating nozzle, comprising a spray pipe, one end of the spray pipe is fixedly connected to a coating liquid injection pipe, the other end of the spray pipe is provided with a threaded groove on the outer surface, the end of the spray pipe away from the coating liquid injection pipe is threadedly connected to a flexible plug, a spray port is provided at the bottom of the spray pipe, the spray port is communicated with the interior of the spray pipe, a cleaning assembly is provided in the spray pipe, and the cleaning assembly is used to clean scale attached to the inner wall of the spray pipe.

[0008] As a further solution of the present invention, threads are provided on the inner wall of the flexible joint plug, and the shape of the threads on the flexible joint plug matches the shape of the thread groove.

[0009] As a further solution of the present invention, the cleaning assembly includes a connecting rod, which slides inside the spray pipe, and a sealing plug is fixedly connected to the surface of the connecting rod. A scraper is fixedly connected to the surface of one end of the connecting rod close to the coating liquid injection pipe, and a cleaning brush cover is fixedly connected between the sealing plug and the scraper, and the inner surface of the cleaning brush cover is fixed to the surface of the connecting rod.

[0010] As a further solution of the present invention, a plurality of filter holes are provided on the scraper, and one end of the scraper close to the coating liquid injection pipe conflicts with one end of the coating liquid injection pipe.

[0011] As a further solution of the present invention, multiple groups of cleaning brushes are fixed on the cleaning brush sleeve, and one end of the cleaning brush away from the middle of the cleaning brush sleeve conflicts with the inner wall of the spray pipe. The cleaning brushes on the cleaning brush sleeve are made of steel.

[0012] As a further solution of the present invention, the shapes and sizes of the scraper and the sealing plug surface match the shapes and sizes of the interior of the spray pipe.

[0013] As a further solution of the present invention, the cleaning assembly also includes a rotating block, which is fixedly connected to one end of the connecting rod away from the coating liquid injection pipe. The top of the rotating block away from the connecting rod is fixedly connected to the fixed rod, and the surface of the fixed rod is rotatably connected to a rotating sleeve.

[0014] As a further solution of the present invention, the rotating sleeve rotates between the rotating block and an end of the fixing rod away from the rotating block.

[0015] The beneficial effects of the utility model are as follows:

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] Example 1

[0032] like Figures 1 to 8As shown, an online cleaning tool for a silicon steel coating nozzle described in an embodiment of the present invention includes a spray tube 1, one end of the spray tube 1 is fixedly connected to a coating liquid injection tube 11, and the outer surface of the other end of the spray tube 1 is provided with a threaded groove 12, and the end of the spray tube 1 away from the coating liquid injection tube 11 is threadedly connected to a flexible plug 13, and a spray port 14 is provided at the bottom of the spray tube 1, and the spray port 14 is communicated with the interior of the spray tube 1, and a cleaning component is provided in the spray tube 1, and the cleaning component is used to clean scale attached to the inner wall of the spray tube 1.

[0033] Specifically, the existing online cleaning tool for silicon steel coating nozzles still has some shortcomings during actual use. The blocked spray port 14 is cleared by a thin iron wire, so that the scale on the inner wall of the spray tube 1 at the spray port 14 is cleaned, and the remaining scaled parts on the inner wall of the spray tube 1 cannot be effectively cleaned. After spraying for a period of time, the scale on the inner wall of the spray tube 1 falls off and still blocks the spray port 14 of the spray tube 1. At the same time, during the production process, when the spray tube 1 is blocked, the staff on the production site need to use iron wire to clean the blocked spray tube 1 on the production line. During this process, the staff need to be close to the running strip steel and equipment, which poses a major safety hazard.

[0034] Therefore, the utility model solves this problem by providing a corresponding structure. When it is necessary to clean the scale on the inner wall of the spray pipe 1, first rotate the flexible joint plug 13 and remove the flexible joint plug 13. At this time, the scale on the inner wall of the spray pipe 1 is cleaned by the cleaning component, and the cleaning component is taken out after the cleaning is completed. The removal of the cleaning component allows the scale cleaned on the inner wall of the spray pipe 1 to be brought out of the inside of the spray pipe 1, thereby keeping the spray port 14 in an unblocked state. After the cleaning is completed, the flexible joint plug 13 is threadedly connected to the spray pipe 1 so that it continues to block one end of the spray pipe 1 at the connection with its thread.

[0035] like Figure 2 and Figure 3 As shown, in this embodiment, threads are provided on the inner wall of the flexible joint plug 13 , and the shape of the threads on the flexible joint plug 13 matches the shape of the thread groove 12 .

[0036] Specifically, when the flexible joint plug 13 is rotated, the threads on the flexible joint plug 13 will be displaced under the guidance of the thread groove 12, and the fixing method of the threaded connection will be tightened.

[0037] Example 2

[0038] like Figures 2 to 8 As shown, compared with Example 1, another implementation of the present utility model is:

[0039] like Figures 4 to 7As shown, the cleaning assembly described in this embodiment includes a connecting rod 21, which slides inside the spray pipe 1, and a sealing plug 22 is fixedly connected to the surface of the connecting rod 21. A scraper 23 is fixedly connected to the surface of one end of the connecting rod 21 close to the coating liquid injection pipe 11, and a cleaning brush cover 24 is fixedly connected between the sealing plug 22 and the scraper 23. The inner surface of the cleaning brush cover 24 is fixed to the surface of the connecting rod 21.

[0040] Specifically, when it is necessary to clean the scale on the inner wall of the spray pipe 1, the flexible joint 13 is no longer fixed to one end of the spray pipe 1, the scraper 23 is aligned with the inside of the spray pipe 1, and the connecting rod 21 is pushed in the direction close to the coating liquid injection pipe 11, so that the connecting rod 21 drives the scraper 23 into the inside of the spray pipe 1. At this time, the threaded groove 12 and the connecting rod 21 are on the same horizontal axis, and the connecting rod 21 is slowly pushed. As the connecting rod 21 is continuously moved, the cleaning brush sleeve 24 and the sealing plug 22 successively enter the inside of the spray pipe 1 until the scraper 23 conflicts with the coating liquid injection pipe 11, and the connecting rod 21 is no longer pushed.

[0041] When the connecting rod 21 rotates, the sealing plug 22, the cleaning brush sleeve 24 and the scraper 23 thereon rotate synchronously in the spray pipe 1, so that the cleaning brush sleeve 24 cleans the scale on the inner wall of the spray pipe 1 and makes it fall into the inside of the spray pipe 1;

[0042] The utility model drives the cleaning brush sleeve 24 fixed thereto to rotate by rotating the connecting rod 21, and the scale on the inner wall of the spray pipe 1 is cleaned by the rotation of the cleaning brush sleeve 24, thereby solving the problem that the existing operation cannot effectively clean the inner wall of the spray pipe;

[0043] When the connecting rod 21 moves in the direction away from the coating liquid injection pipe 11, the scraper 23 is driven to move inside the spray pipe 1 along with the connecting rod 21, and the impurities brushed off and deposited by the cleaning brush sleeve 24 in the spray pipe 1 are cleaned out of the interior of the spray pipe 1 by the scraper 23, so that the interior of the spray pipe 1 remains clean.

[0044] like Figures 4 to 6 As shown, the scraper blade 23 of this embodiment is provided with a plurality of filter holes, and one end of the scraper blade 23 close to the coating liquid injection pipe 11 is in conflict with one end of the coating liquid injection pipe 11 .

[0045] Specifically, the filter holes provided on the scraper 23 allow the scraper 23 to filter the liquid during the cleaning process as it moves away from the coating liquid injection pipe 11, and to bring the precipitated impurities out of the spray pipe 1 through the scraper 23 and the filter holes thereon; the size of the port of the coating liquid injection pipe 11 is smaller than the size of the port of the spray pipe 1, so that the scraper 23 conflicts with the coating liquid injection pipe 11, thereby blocking the displacement of the connecting rod 21, so that the staff knows that the scraper 23 has moved to the farthest distance.

[0046] like Figures 4 to 6 As shown, in this embodiment, multiple groups of cleaning brushes are fixed on the cleaning brush cover 24, and one end of the cleaning brush away from the middle of the cleaning brush cover 24 conflicts with the inner wall of the spray pipe 1. The cleaning brushes on the cleaning brush cover 24 are made of steel.

[0047] Specifically, when the cleaning brush sleeve 24 rotates, the steel cleaning brush thereon rotates synchronously with the cleaning brush sleeve 24 , thereby cleaning and scrubbing the scale on the inner wall of the spray pipe 1 that is in conflict with the cleaning brush sleeve 24 .

[0048] like Figure 4 As shown, the shapes and sizes of the scraper blade 23 and the surface of the sealing plug 22 in this embodiment match the shapes and sizes of the interior of the spray pipe 1.

[0049] Specifically, their shapes and sizes match each other so that when the scraper 23 and the sealing plug 22 enter the spray pipe 1, the connecting rod 21 and the spray pipe 1 are on the same horizontal axis.

[0050] like Figures 4 to 7 As shown, the cleaning assembly described in this embodiment also includes a rotating block 25, which is fixedly connected to the end of the connecting rod 21 away from the coating liquid injection pipe 11, and the top of the end of the rotating block 25 away from the connecting rod 21 is fixedly connected to a fixed rod 26, and the surface of the fixed rod 26 is rotatably connected to a rotating sleeve 27.

[0051] Specifically, when the scraper blade 23 collides with the coating liquid injection pipe 11, the worker holds the rotating sleeve 27 and rotates it around the connecting rod 21. During this process, the fixed rod 26 is subjected to the force of the rotating sleeve 27 held by the worker, causing the rotating block 25 and the fixed rod 26 thereon to rotate around the connecting rod 21 as the axis, and causing the fixed rod 26 to rotate relatively within the rotating sleeve 27.

[0052] During online cleaning, the utility model does not require workers to get close to the running strip steel and equipment to clean the spray pipe 1. The cleaning operation is simple and safe, the cleaning tool is practical and convenient, and the cleaning effect is significant.

[0053] like Figure 8As shown, the rotating sleeve 27 of this embodiment rotates between the rotating block 25 and an end of the fixing rod 26 away from the rotating block 25 .

[0054] Specifically, the setting of the rotating sleeve 27 allows the staff to rotate the fixed rod 26 and the rotating block 25 thereon with the connecting rod 21 as the axis through the rotating sleeve 27. The rotating sleeve 27 held by the staff is in a relatively stationary state while the fixed rod 26 and the rotating block 25 are in a relative motion state, allowing the staff to rotate the connecting rod 21 in a more comfortable manner.

[0055] Working principle:

[0056] When it is necessary to clean the scale on the inner wall of the spray pipe 1, first rotate the flexible plug 13 and remove the flexible plug 13. At this time, the flexible plug 13 is no longer fixed to one end of the spray pipe 1. Align the scraper 23 with the inside of the spray pipe 1 and push the connecting rod 21 in the direction close to the coating liquid injection pipe 11, so that the connecting rod 21 drives the scraper 23 into the inside of the spray pipe 1. At this time, the threaded groove 12 and the connecting rod 21 are on the same horizontal axis. Continue to push the connecting rod 21 slowly. As the connecting rod 21 continues to move, the cleaning brush sleeve 24 and the sealing plug 22 successively enter the inside of the spray pipe 1 until the scraper 23 conflicts with the coating liquid injection pipe 11. At this time, the connecting rod 21 is no longer pushed;

[0057] At this time, the staff holds the rotating sleeve 27 and rotates it around the connecting rod 21. During this process, the fixed rod 26 is subjected to the force of the rotating sleeve 27 held by the staff, causing the rotating block 25 and the fixed rod 26 thereon to rotate around the connecting rod 21 as the axis, and causing the fixed rod 26 to rotate relatively within the rotating sleeve 27.

[0058] When the connecting rod 21 rotates, the sealing plug 22, the cleaning brush sleeve 24 and the scraper 23 thereon rotate synchronously in the spray pipe 1, so that the cleaning brush sleeve 24 cleans the scale on the inner wall of the spray pipe 1 and makes it fall into the inside of the spray pipe 1;

[0059] When the connecting rod 21 moves in a direction away from the coating liquid injection pipe 11, the scraper 23 is driven to move together with the connecting rod 21 inside the spray pipe 1, and the impurities that are brushed off and deposited by the cleaning brush sleeve 24 in the spray pipe 1 are cleaned out of the interior of the spray pipe 1 by the scraper 23, so that the interior of the spray pipe 1 remains clean, and the spray port 14 remains unblocked.

[0060] After cleaning, the flexible plug 13 is threadedly connected to the spray pipe 1 so as to continue to block one end of the spray pipe 1 at the threaded connection with the spray pipe 1 .

[0061] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
