[0006] , ,

[0001] The present invention relates to the technical field of the production of grain-oriented electrical steel, and particularly relates to a dynamic anti-blocking filter for pipeline transportation of an end face inhibitor of grain-oriented electrical steel and a pipeline system using the filter. Background Art

[0002] Grain-oriented electrical steel is a key soft magnetic material in the fields of aerospace and military industry. Ring furnace annealing is the core process that determines the magnetic properties of grain-oriented electrical steel. However, during the heating-cooling cycle of the steel coil, internal and external stress differences are generated due to the radial temperature difference, inducing plastic deformation and interlayer adhesion, resulting in edge cracking during subsequent skin pass annealing. Practical experience shows that applying magnesium oxide-boric acid inhibitor to the end face of the steel coil before high-temperature annealing in the ring annealing furnace can effectively reduce the generation of edge cracking.

[0003] The process of manually brushing magnesium oxide-boric acid inhibitor on-site has a high labor intensity and uneven coating.

[0004] Although the automatic coating device equipped in the silicon steel production line can replace manual labor, its transportation pipeline filter has defects. The magnesium oxide-boric acid mixed particles are extremely easy to deposit, hydrate and solidify into dense hard blocks at the bottom of the filter for pipeline transportation of the end face inhibitor of grain-oriented electrical steel. Once blocked, maintenance requires detecting the blockage position and disassembling the pipeline for fixed-point dredging, which is very inconvenient. Therefore, there is an urgent need to develop an anti-blocking filter for pipeline transportation of the end face inhibitor of grain-oriented electrical steel that is not easily blocked and has stable operation to ensure the continuous and high-quality production of grain-oriented electrical steel. Summary of the Invention

[0005] The main purpose of the present invention is to address the above-mentioned defects existing in the prior art, and provide a dynamic anti-blocking filter for the end face inhibitor of grain-oriented electrical steel and its pipeline system, which has the characteristics of not being easily blocked, being stable and efficient, and being convenient for maintenance.

[0006] The technical solution adopted by the present invention is as follows: A dynamic anti-blocking filter for the end face inhibitor of grain-oriented electrical steel includes a feed inlet, a discharge outlet, a discharge port, a shunt pipe, and a particle suspension chamber provided with a sieve inside; An upper joint pipe and a lower joint pipe are hermetically connected to the outside of one side of the particle suspension chamber, and the sieve covers the upper joint pipe to separate the particle suspension chamber from the discharge outlet; The lower joint pipe is connected to the first end of the shunt pipe, and is respectively connected to the feed inlet and the discharge outlet through the bifurcated pipes at the second end of the shunt pipe, forming a main filtration passage from the feed inlet through the particle suspension chamber to the discharge outlet, and a waste discharge passage from the discharge outlet through the particle suspension chamber to the discharge port; on the bifurcated pipes at the second end, opening and closing switching valves are respectively provided to switch the shunt pipe to connect to the feed inlet of the main filtration passage or the discharge port of the discharge passage.

[0007] In the above technical solution, the first section of the diversion pipe is set horizontally, one of the branch pipes at the second end of the diversion pipe extends upward to connect with the feed inlet, and one of the branch pipes at the second end of the diversion pipe extends upward at an incline and then extends downward vertically to form a discharge outlet.

[0008] In the above technical solution, an on / off switching valve is installed at the vertically downward extension section of one of the branch pipes at the second end of the diversion pipe; an on / off switching valve is installed at the upward extension section of one of the branch pipes at the second end of the diversion pipe.

[0009] In the above technical solution, the particle suspension chamber is triangular in its forward projection, with an upper connector pipe and a lower connector pipe arranged outward from one side of the triangle; the projection of the triangle vertex corresponding to that side is not lower than the lower edge of the upper connector pipe. Thus, by using fluid kinetic energy to flush the particles along the upward direction of the chamber space and maintain a dynamic suspension layer, the particle suspension chamber, the screen, and the upper and lower connector pipes form a dynamic suspension module, suppressing deposition and clogging.

[0010] In the above technical solution, the particle suspension chamber is a right-angled triangle in its forward projection, with an upper connector pipe and a lower connector pipe arranged outward from one side of the triangle; the projection of the triangle vertex corresponding to that side is flush with the upper edge of the upper connector pipe, forming a right angle. Thus, by utilizing fluid kinetic energy to extend upward along the chamber space to the highest point, the dynamic travel and flushing force of the particles are increased, thereby maintaining a dynamic suspension layer and inhibiting deposition and blockage.

[0011] In the above technical solution, the bottom plate connecting the particle suspension chamber to the apex of the triangle and the lower edge of the lower connector pipe of the suspension chamber include at least an upwardly inclined slope connection structure. This allows the particles to be flushed along the slope using fluid kinetic energy, maintaining a dynamic suspension layer and suppressing deposition and blockage.

[0012] In the above technical solution, the upper connector pipe and the lower connector pipe are integrally set and fixed to the particle suspension chamber by bidirectional sealing through the adapter plate, and are connected to one side of the particle suspension chamber, which has a triangular projection in the front direction.

[0013] When the upper and lower connector tubes are installed as a single unit, the interfaces on both sides of the adapter plate are different, so they cannot be directly sealed with a sealing ring. Therefore, an adapter plate is installed to connect the two sides, and a sealing strip is installed in the slot of the adapter plate to form a seal.

[0014] In the above technical solution, the height of the feed inlet is preferably higher than that of the discharge outlet and the upper edge of the particle suspension chamber, and the height of the discharge outlet is preferably higher than that of the upper edge of the particle suspension chamber and the discharge port.

[0015] In the above technical solution, the particle suspension chamber, the upper connector pipe, the lower connector pipe, and the diversion pipe are connected by flanges.

[0016] In the above technical solution, the switching valve can be a ball valve or a gate valve.

[0017] In the above technical solution, the screen is fixed between the particle suspension chamber and the upper connector pipe by an adapter plate.

[0018] In the above technical solution, the adapter plate is integral, with an upper connector pipe hole and a lower connector pipe hole in the center. Around each pipe hole, sealing grooves are provided on the front and back of the adapter plate to seal and connect with the screen, the upper connector pipe hole and the lower connector pipe hole.

[0019] In the above technical solution, when the main filtration channel is working, the switching valve on the branch pipe at the second end of the diversion pipe and the pipeline connected to the feed inlet remains open, and the switching valve on the pipeline connected to the discharge outlet remains closed; material is fed from the feed inlet and discharged from the discharge outlet.

[0020] In the above technical solution, when the discharge passage is working, the switching valve on the pipeline connecting the branch pipe at the second end of the diversion pipe to the feed inlet remains closed, and the switching valve on the pipeline connecting the branch pipe to the discharge outlet remains open; water is introduced from the discharge outlet for flushing, and material and water are discharged from the discharge outlet.

[0021] In the above technical solution, a main filtration passage is formed, consisting of inlet → diversion pipe → lower connector of suspension chamber → particle suspension chamber → upper connector screen of suspension chamber → outlet, and a discharge passage is formed, consisting of outlet → upper connector screen of suspension chamber → particle suspension chamber → lower connector of suspension chamber → diversion pipe → discharge port.

[0022] Based on the above, the present invention also provides a oriented silicon steel end face inhibitor anti-clogging pipeline system, which uses the oriented silicon steel end face inhibitor dynamic anti-clogging filter described in any of the above claims.

[0023] Based on the above, the present invention also provides a dynamic filtration method for preventing blockage of end-face inhibitor pipelines of oriented silicon steel. The method uses the dynamic anti-blockage filter for end-face inhibitor of oriented silicon steel described in any of the above-mentioned embodiments, with the main filtration passage closed, water entering from the outlet for rinsing, and then discharging material and water through the discharge outlet.

[0024] Based on the above, the present invention also provides a dynamic filtration method for preventing blockage in a oriented silicon steel end-face inhibitor pipeline. Using the dynamic anti-blockage filter for oriented silicon steel end-face inhibitor described in any of the above-mentioned methods, the material is fed from the inlet, and the particles are dynamically suspended and layered in the particle suspension chamber, maintaining a non-clumped state. The mixture is filtered and discharged from the outlet.

[0025] Through the above technical solutions, this invention essentially discloses a dynamic anti-clogging filter for oriented silicon steel end-face inhibitor pipeline transportation and a pipeline system using it. This filter essentially forms a dynamic filtration structure composed of an inlet pipeline module, an outlet pipeline module, a discharge pipeline module, and a dynamic suspension module. The modules and the pipelines between the modules are connected by flanges. In the core dynamic suspension module, a screen is provided between the particle suspension chamber and the transfer plate to intercept inhibitor agglomerates with a particle size exceeding the critical value. A diversion pipe structure is used to achieve fluid flow between the inlet pipeline module, the outlet pipeline module, and the dynamic suspension module. Through these measures, continuous anti-clogging function is achieved without an external power source, featuring long maintenance cycles, resistance to clogging, and stable and efficient operation.

[0026] Compared with the prior art, the beneficial effects of this invention are: Compared to existing magnesium oxide inhibitor pipeline filters suitable for similar scenarios, where large particles are trapped in the filter element as the solution passes through, and these particles accumulate over time, causing pressure loss and clogging, this invention utilizes a uniquely designed dynamically stratified particle suspension chamber. The kinetic energy of the transported fluid drives the trapped large particles in the chamber to form a dynamic suspension layer (because magnesium oxide suspension clumps after settling), thus avoiding the clogging problems caused by static deposition in traditional filters. Therefore, it is particularly suitable for achieving continuous anti-clogging without the need for an external power source.

[0027] The present invention employs a slow transition design between pipes, such as between the upper and lower joints of the suspension chamber and the particle suspension chamber. This slow transition design eliminates cleaning dead zones, thus maximizing the efficiency of fluid kinetic energy cleaning and removing large particles remaining in the pipes to the greatest extent possible, preventing blockages caused by continuous particle deposition and agglomeration.

[0028] This invention is ingeniously conceived and features an original dual-loop design that combines a main filtration path with a discharge path. The main path enables dynamic anti-clogging filtration, while the discharge path cleaning process can remove magnesium oxide particles from the pipes to the greatest extent possible without disassembling them. This further prevents magnesium oxide particles from settling and caking in the pipes when the equipment is shut down, allowing for convenient maintenance without disassembly.

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0040] Example 1 refer to Figures 1-2, Figures 4-9 As shown, the present invention provides a dynamic anti-clogging filter for a silicon steel end-face inhibitor pipeline, comprising an inlet pipeline module, an outlet pipeline module, a discharge pipeline module, and a dynamic suspension module. The modules and the pipelines between the modules are connected by flanges. A screen 13 is provided between the particle suspension chamber 1 and the adapter plate 12 in the dynamic suspension module. The inlet pipeline module, the outlet pipeline module, and the dynamic suspension module are connected by a diversion pipe 4.

[0041] The feed pipe module includes a feed inlet straight pipe 7, a feed inlet right-angle pipe 8, and a feed inlet ball valve 9; the discharge pipe module includes a discharge outlet bend 10 and a discharge outlet straight pipe 11; the discharge pipe module includes a discharge outlet ball valve 5 and a discharge pipe 6; the dynamic suspension module includes a particle suspension chamber 1, a suspension chamber upper connector pipe 2, a suspension chamber lower connector pipe 3, an adapter plate 12, and a screen 13.

[0042] The diverter 4 is divided into the diverter impact zone 25, the diverter turbulence zone 26, the diverter uphill zone 27, the diverter vertical descent section 28, and the diverter vertical ascent section 30.

[0043] The particle suspension chamber 1 has a suspension chamber ramp 21 and a suspension chamber settling zone 20 in the inner cavity 22. The end face of the particle suspension chamber 1 is provided with a suspension chamber screen groove 34 and a suspension chamber rectangular sealing groove 35.

[0044] With this structure, the inner cavity 22 of the suspension chamber is equipped with a suspension chamber ramp 21 and a suspension chamber settling zone 20. Large particles remaining in the inner cavity 22 will fall onto the suspension chamber ramp 21 and then roll down to the suspension chamber settling zone 20. The suspension chamber settling zone 20 is located at the lower connector interface 19 of the suspension chamber. The inhibitor flows from the lower connector interface 19 to the suspension chamber settling zone 20, generating eddies in the inner cavity 22 of the suspension chamber. The eddies carry large particles in the suspension chamber settling zone 20 into suspension, preventing large particles from depositing and agglomerating.

[0045] The front of the adapter plate 12 is provided with an adapter plate screen fixing boss 31 and an adapter plate rectangular sealing groove 32, which correspond to the suspension chamber screen groove 34 and the suspension chamber rectangular sealing groove 35. The back of the adapter plate 12 is provided with an adapter plate square sealing groove 33, which corresponds to the suspension chamber upper connector square sealing groove 36 and the suspension chamber lower connector square sealing groove 37.

[0046] With this structure, the rectangular sealing groove 32 of the adapter plate corresponds to the rectangular sealing groove 35 of the suspension chamber, which can achieve the sealing between the adapter plate 12 and the particle suspension chamber 1. The square sealing groove 33 of the adapter plate corresponds to the square sealing groove 36 of the upper connector and the square sealing groove 37 of the lower connector of the suspension chamber, which can achieve the sealing between the adapter plate 12 and the upper connector pipe 2 and the lower connector pipe 3 of the suspension chamber.

[0047] The upper connector pipe 2 of the suspension chamber transitions the square upper connector pipe 15 of the suspension chamber into the round upper connector pipe 16 of the suspension chamber.

[0048] The lower connector pipe 3 of the suspension chamber transforms the square lower connector pipe 18 of the suspension chamber into a round lower connector pipe 17 of the suspension chamber.

[0049] With this structure, the upper connector pipe 2 of the suspension chamber transitions from the square connector pipe 15 to the circular connector pipe 16, achieving a seamless connection between the particle suspension chamber 1 and the outlet bend pipe 10 without any abrupt geometric changes. Similarly, the lower connector pipe 3 of the suspension chamber transitions from the square connector pipe 18 to the circular connector pipe 17, achieving a seamless connection between the particle suspension chamber 1 and the diversion pipe 4 without any abrupt geometric changes. This seamless connection effectively prevents particles from settling and agglomerating in corners during filter operation.

[0050] The upper connector pipe 2 and the lower connector pipe 3 of the suspension chamber are connected to the particle suspension chamber 1 through the adapter plate 12.

[0051] The screen 13 is provided with screen skirt 23 and screen fixing hole 24; the screen fixing hole 24 is installed on the screen fixing boss 31 of the adapter plate and is fixed by the screen groove 34 of the suspension chamber.

[0052] With this structure, the screen fixing boss 31 of the adapter plate and the screen groove 34 of the suspension chamber are fixedly installed, which can completely fix the position of the screen 13. The screen skirt 23 is located in the gap between the particle suspension chamber 1 and the adapter plate 12. The particle suspension chamber 1 and the adapter plate 12 clamp the screen skirt 23, which can further fix the position of the screen 13, reduce the load on the screen fixing hole 24, and make the force on the edge of the screen 13 more balanced.

[0053] The discharge pipe 6 is equipped with a discharge pipe contraction section 29. With this structure, the discharge pipe contraction section 29 can be connected to a small-diameter flexible hose connector.

[0054] Figure 2 In the middle, the positive projection direction of particle suspension chamber 1 (equivalent to Figure 1 The triangle (perpendicular to the plane of the paper) is a right triangle. An upper connector pipe 2 and a lower connector pipe 3 are installed outwards from one side of the triangle. The projection of the triangle vertex corresponding to that side onto the upper edge of the upper connector pipe forms a right angle. Thus, by utilizing fluid kinetic energy to extend upwards along the internal space to the highest point, the dynamic travel and flushing force of the particles are increased, thereby maintaining a dynamic suspension layer and inhibiting sedimentation and blockage.

[0055] In an optional embodiment, the particle size of the sieve 13 is 20-60 mesh, preferably 35-45 mesh.

[0056] The screen 13 is made of stainless steel, which can withstand high temperature corrosion and can be replaced regularly when needed.

[0057] The working principle of this invention is as follows: It is mainly divided into three processes: operation, forward cleaning, and reverse cleaning.

[0058] The first step of the operation process is as follows: Open the inlet ball valve 9 and close the outlet ball valve 5. Pump the inhibitor into the inlet, and it passes through the inlet right-angle pipe 8 and the inlet ball valve 9 into the diversion pipe 4. The diversion pipe 4 has a Y-shaped branch because the inhibitor flows from the inlet to the outlet. The diversion pipe 4 has a geometric change in the turbulent zone 26, where the inhibitor will form turbulence. This turbulence can prevent inhibitor particles from depositing and agglomerating in the diversion pipe impact zone 25, the diversion pipe turbulent zone 26, and the diversion pipe upslope 26. With the outlet ball valve 5 closed and the diversion pipe 4 having an upslope 26, the pumped inhibitor will not enter the vertical descending section 28 of the diversion pipe for deposition during operation.

[0059] The second step of the operation process: The inhibitor enters the particle suspension chamber 1 through the diversion pipe 4 and the lower connector pipe 3. Large particles are retained in the particle suspension chamber 1 by the filtration of the screen 13. The remaining inhibitor is discharged from the outlet through the upper connector pipe 2, the outlet bend 10, and the outlet straight pipe 11. The inner cavity 22 of the suspension chamber is equipped with a suspension chamber ramp 21 and a suspension chamber settling zone 20. Large particles retained in the inner cavity 22 fall onto the suspension chamber ramp 21 and then roll down to the suspension chamber settling zone 20. The suspension chamber settling zone 20 is located at the lower connector interface 19 of the suspension chamber. The inhibitor flows from the lower connector interface 19 to the suspension chamber settling zone 20, generating eddies in the inner cavity 22 of the suspension chamber. The eddies carry the large particles on the suspension chamber settling zone 20 into suspension, preventing large particles from settling and agglomerating.

[0060] Forward cleaning process: Open the inlet ball valve 9 and close the outlet ball valve 5. Pump clean water into the inlet, and it flows through the inlet right-angle pipe 8, inlet ball valve 9, diverter pipe 4, lower connector pipe 3 of the suspension chamber, particle suspension chamber 1, upper connector pipe 2 of the suspension chamber, outlet bend pipe 10, and outlet straight pipe 11 before being discharged from the outlet. This step mainly cleans the inhibitor solution in the filter transport path, but does not include large particles remaining in the particle suspension chamber 1, and does not clean the pipes at the waste discharge outlet.

[0061] Reverse cleaning process: Close the feed port ball valve 9, open the discharge port ball valve 5, pump clear water from the discharge port, and discharge it from the waste discharge port through the discharge port straight pipe 11, discharge port elbow 10, upper joint pipe 2 of the particle suspension bin, particle suspension bin 1, lower joint pipe 3 of the suspension bin, shunt pipe 4, discharge port ball valve 5, and discharge pipeline 6. During this process, large particles fall on the suspension bin slope 21 and then roll into the suspension bin settling area 20. The suspension bin settling area 20 is located at the lower joint interface 19 of the suspension bin, and there is no sudden change in geometric structure along the way, which is convenient for the clear water to carry the large particles out of the pipeline. When the large particles flow through the Y-shaped fork of the shunt pipe 4, because the uphill section 27 of the shunt pipe is gentler than the vertical rising section 30 of the shunt pipe, the large particles carried by the clear water will impact the impact area 25 of the shunt pipe and enter the uphill section 27 of the shunt pipe to be discharged from the pipeline. Even if a small amount of large particles enter the vertical rising section 30 of the shunt pipe, due to the closure of the feed port ball valve 9 and the vertical state of the vertical rising section 30 of the shunt pipe, the large particles will settle due to their own weight and still be carried by the clear water into the uphill section 27 of the shunt pipe to be discharged from the pipeline.

[0062] Example 2 Refer to Figure 1 、 Figures 3-9 As shown, different from Example 1, in this example, Figure 3 In the forward projection direction of the particle suspension bin 1 (equivalent to Figure 1 the direction perpendicular to the paper surface), it is triangular, and the upper joint pipe 2 and the lower joint pipe 3 are arranged outward on the side where one side of the triangle is located; the projection of the corresponding triangular vertex of this side on this side is not lower than the lower edge of the upper joint pipe.

[0063] This effect is a bit weaker than the dynamic suspension separation filtration effect of the example, but it can also be used as a better method under space constraints. Because of the good dynamic suspension separation effect, the anti-blocking effect is still better than the orientation silicon steel end inhibitor pipeline transport filter set on the automatic coating device supporting the traditional silicon steel production line.

[0064] Example 3 Set up a silicon steel end inhibitor pipeline system on the automatic coating device supporting the silicon steel production line, and use the filter of Example 1 or 2.

[0065] Example 4 In this example, an anti-blocking filtration method for the orientation silicon steel end inhibitor pipeline is implemented, and the anti-blocking filter of Example 1 or 2 or 3 is used.

[0066] When flushing and removing blockages are required, the main filtration path is closed, and water is flushed in from the discharge port, and discharged through the discharge port together with the water.

[0067] When normal filtration is required, the discharge path is closed, feed is carried out from the feed port, and after the particles are dynamically suspended and stratified in the particle suspension bin, they are discharged from the discharge port after filtration.

[0068] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
