Description

Technical Field

[0001] The invention relates to the field of silicon steel pickling, and in particular to a silicon steel pickling device and a pickling method. Background Art

[0002] Silicon steel, as a silicon alloy steel, has been widely used in the electronics and power industries for its high magnetic permeability, low coercivity and significant resistivity. Silicon steel is mainly divided into two categories: hot-rolled silicon steel and cold-rolled silicon steel. In the production process of hot-rolled silicon steel, harmful substances such as oxides and rust will inevitably form on the surface of silicon steel. These impurities not only affect the surface quality of the product, but also shorten the service life of silicon steel and reduce its electromagnetic properties. Therefore, pickling treatment has become an indispensable key link in the production of hot-rolled silicon steel.

[0003] The pickling operation is usually carried out before silicon steel is cut. At this time, the silicon steel is transported in the form of long strips and immersed in a specific acid solution. The acid solution reacts chemically with the surface material of the silicon steel to achieve the purpose of cleaning and purifying the surface. To ensure the comprehensiveness of the pickling, the long silicon steel strips need to pass through a moving device during the pickling process so that each part can fully contact the acid solution. Therefore, the existing pickling devices mostly use a roller system to guide the silicon steel into the acid pool and provide the necessary tension to promote its smooth movement.

[0004] However, when silicon steel is loaded into the existing pickling device, it needs to pass around these rollers one by one. This step not only makes the operation of the existing pickling device cumbersome, but also increases the risk of direct contact with acid liquid by personnel, resulting in low safety of personnel operating the existing pickling device. That is, the existing pickling device still has usage defects. Summary of the invention

[0021] Beneficial effects of the present invention:

DETAILED DESCRIPTION

[0036] It should be noted that the technical solution of the present invention will be described in detail and completely below in combination with the drawings provided by the present invention and the marks in the drawings, corresponding to the technical solution of the present invention. However, the described content must only be one of the embodiments presented by the technical solution of the present invention, and cannot cover all the contents of the present invention. Therefore, based on the embodiments listed in the present invention, any embodiments derived from the embodiments obtained by those skilled in the art without substantial creation shall fall within the scope of protection of the present invention.

[0037] Embodiment: A silicon steel pickling device, such as Figure 1-Figure 5 As shown, it includes: a pickling tank 1, in which an acid solution for treating silicon steel surface materials is installed; a bracket 2 fixedly installed on both sides of the front side wall of the pickling tank 1; a double-headed worm 3 rotatably installed between the brackets 2, and the textures at both ends of the double-headed worm 3 are set in opposite directions; a motor a4 fixedly installed on the bracket 2, and the output end of the motor a4 is fixed to the double-headed worm 3; a slide rail 5 fixedly installed on the front and rear side walls of the pickling tank 1; a moving frame 6 slidably installed on the slide rail 5, and the moving frame 6 is provided with two groups, which are respectively arranged on the left and right sides of the slide rail 5; a guide roller a7 rotatably installed on the moving frame 6, and the guide roller a7 is used For guiding and stretching silicon steel; rotating the rotating frame a8 installed on the mobile frame 6; rotating the guide roller b9 installed on the rotating frame a8, the rotating frame a8 rotates, and the direction and position of the silicon steel will be changed through the guide roller b9; rotating the worm gear 10 installed on the mobile frame 6, the worm gear 10 is fixedly installed on the rotating frame a8, and the worm gear 10 on the two groups of mobile frames 6 are respectively engaged with the textures at both ends of the double-headed worm 3; the limiting strip 11 is fixedly installed on the mobile frame 6, and the limiting strip 11 is located on the side of the mobile frame 6 facing the middle of the pickling tank 1; the material moving components for moving silicon steel are arranged on both sides of the pickling tank 1.

[0038] like Figure 2 As shown, the end of the silicon steel is passed through between the guide roller a7 and the guide roller b9 on each group of movable frames 6, and then the end of the silicon steel is fixed on the material transfer assembly. The movable assembly will control the movement of the silicon steel by winding the silicon steel; before starting the material transfer assembly, start the motor a4 to control the rotation of the double-headed worm 3, and the double-headed worm 3 will control the two worm wheels 10 to rotate synchronously and in the opposite direction, driving the rotating frame a8 to rotate downward toward the center line of the pickling tank 1, so that the guide roller b9 can guide the silicon steel to bypass the guide roller a7 and move downward, so that the silicon steel section between the two groups of movable frames 6 is immersed in the pickling tank 1 by the guide roller b9, and then after the rotating frame a8 contacts the limiting strip 11, the limiting strip 11 prevents the worm wheel 10 from rotating by resisting the rotating frame a8, and then the double-headed worm 3 moves the movable frame 6 toward the center of the pickling tank 1 through the worm wheel 10, and the two groups of movable frames 6 approach each other, and the final state is as follows Figure 4As shown, at this time, the silicon steel successively passes around the guide rollers a7 and b9 on the two groups of movable frames 6. Therefore, when the material transfer assembly moves the silicon steel later, under the guiding action of the guide roller b9, each position of the silicon steel can be immersed in the acid solution, and the guide roller a7 can give tension to the silicon steel, so that the material transfer assembly can better move the silicon steel guided to the pickling tank 1.

[0039] In summary, the operation in the entire process of loading silicon steel becomes simpler, and the step of loading silicon steel is performed above the pickling tank 1. Therefore, it is possible to avoid the need for personnel to guide the silicon steel in the acid solution to pass through each roller in turn, and avoid close contact with the acid solution, thereby effectively improving the operational safety of personnel. Therefore, the use of this pickling device has significantly better use effect than the prior art.

[0040] like Figure 1-Figure 2 As shown, the material moving assembly includes: a support frame a12 arranged on the left side of the pickling tank 1, the support frame a12 is used to place the silicon steel coil; a support frame b13 arranged on the right side of the pickling tank 1; a reel 14 detachably rotatably mounted on the support frame b13, the core can be fitted and fixed on the reel 14, the core is used to reel up the silicon steel that has been pickled; a motor b15 fixedly mounted on the front side of the support frame b13, the motor b15 is a double-headed motor; gears 16 fixedly mounted on the front end of the reel 14 and the rear end output end of the motor b15, respectively, the gear 16 at the front end of the reel 14 is larger than the gear 16 at the output end of the motor b15, and the two gears 16 are meshed, so that the motor b15 reduces the speed to drive the reel 14 to rotate.

[0041] Place the silicon steel coil to be pickled on the support frame a12, the silicon steel coil can rotate on the support frame a12, remove the reel 14, and then fix the core on the reel 14, then pull out the end of the silicon steel, pass through the guide rollers a7 and b9 on the two sets of mobile frames 6 in turn, and finally fix the end of the silicon steel on the core, that is, the loading of the silicon steel is completed; start the motor b15, and through the transmission of the gear 16, the silicon steel is rolled up at a uniform speed, and then the silicon steel can be moved from left to right at a uniform speed. The setting of the material moving component enables the pickling device to achieve the purpose of moving the silicon steel, and at the same time, it can neatly roll up the silicon steel that has been pickled, which is convenient for the subsequent processing of the silicon steel; and the silicon steel is moved at a uniform speed, which will ensure the uniformity of the pickling of the silicon steel.

[0042] like Figure 1 , Figure 5 and Figure 6As shown, it also includes: a rotating frame 17 rotatably installed in the pickling tank 1; a support shaft 18 fixedly installed on the rotating frame 17, and four support shafts 18 are arranged on the rotating frame 17, and the support shaft 18 is far away from the rotation axis of the rotating frame 17; a stirring roller 19 rotatably installed on each support shaft 18, and the rotating frame 17 rotates to stir the acid solution and stir the silicon steel through the stirring roller 19; a transmission wheel 20 fixedly installed on the front end of the rotating frame 17 and the front output end of the motor b15 respectively; a transmission belt 21 wound between the two transmission wheels 20, and the diameter of the transmission wheel 20 of the rotating frame 17 is larger than the transmission wheel 20 of the motor b15, so that the motor b15 reduces the speed to drive the rotating frame 17 to rotate.

[0043] When the motor b15 is started, the rotating frame 17 is controlled to rotate the paddle roller 19. Since the rotating speed of the rotating frame 17 is slow, the paddle roller 19 deviating from the rotating axis of the rotating frame 17 can change the position of the acid liquid around it, so that the acid liquid can flow, wherein the acid liquid after reacting with the silicon steel can be dispersed, and the remaining acid liquid that has not reacted with the silicon steel can be close to the silicon steel, thereby making full use of the acid liquid in the pickling tank 1, avoiding the acid liquid after the reaction from gathering near the silicon steel to cause insufficient reaction with the silicon steel surface material, and improving the effect of the acid liquid on the silicon steel surface material treatment; at the same time, the paddle roller 19 can also contact with the silicon steel, and continuously shake the silicon steel to shake off the residues after the reaction on the silicon steel surface to avoid residues remaining on the silicon steel, thereby ensuring the treatment quality of the silicon steel by the pickling device.

[0044] like Figure 1 , Figure 7 and Figure 8 As shown, it also includes: a decontamination tank 22 fixedly installed on the left side of the pickling tank 1, and a support frame a12 fixedly installed in the decontamination tank 22; a water storage barrel 23 fixedly installed on the left side of the decontamination tank 22; a nozzle 24 fixedly installed on the decontamination tank 22, and the nozzle 24 faces the support frame a12; a pump body 25 fixedly installed on the decontamination tank 22, and the pump body 25 connects the nozzle 24 and the water storage barrel 23 to transport the water in the water storage barrel 23 to the nozzle 24; a fixed frame 26 fixedly installed on the support frame a12; a guide brush a27 rotatably installed on the fixed frame 26; a rotating frame b28 rotatably installed on the fixed frame 26; a pressing brush a29 rotatably installed on the rotating frame b28; a torsion spring 30 fixedly installed between the rotating frame b28 and the fixed frame 26, and the torsion spring 30 acts to make the pressing brush a29 close to the silicon steel coil on the support frame a12.

[0045] After the silicon steel coil is placed on the support frame a12, the thickness of the silicon steel coil squeezes the pressing brush a29 to rotate in the direction away from the silicon steel coil, and the torsion spring 30 is twisted, so the torsion spring 30 can make the pressing brush a29 close to the surface of the silicon steel coil; afterwards, when taking out the end of the silicon steel, it is necessary to pass the end of the silicon steel through the guide brush a27 and the pressing brush a29. At this time, the pressing brush a29 is located on the upper surface of the silicon steel and the guide brush a27 is located on the lower surface of the pressing brush a29; after fixing the end of the silicon steel, the material moving assembly is controlled to start moving the silicon steel while starting the pump body 25. The pump body 25 sprays water on the silicon steel through the nozzle 24. As the silicon steel moves, the guide brush a27 and the pressing brush a29 respectively roll in contact with the upper and lower surfaces of the silicon steel, and cooperate with the water to brush the silicon steel to remove impurities on the surface of the silicon steel that can be easily removed. Finally, the impurities and waste water cleaned out are collected in the decontamination tank 22 and wait for subsequent unified treatment.

[0046] By pre-decontamination of silicon steel, some simple impurities on the surface of silicon steel are removed. In this way, when the silicon steel is subsequently pickled, the acid can mainly chemically react with the impurities on its surface that are difficult to handle, rather than wasting time on the impurities that can be easily removed, thereby improving the utilization rate of the acid.

[0047] like Figure 1 , Figure 7 and Fig. 9 As shown, it also includes: a deacidification tank 31 fixedly installed on the right side of the pickling tank 1, a support frame b13 fixedly installed in the deacidification tank 31, and a cleaning liquid for washing away residual acid on the upper silicon steel is loaded in the deacidification tank 31; a guide brush b32 rotatably installed on the support frame b13; a sliding frame 33 slidably installed on the support frame b13; a pressing brush b34 rotatably installed on the sliding frame 33; an electric push frame 35 fixedly installed on the right side of the deacidification tank 31, the control end of the electric push frame 35 is fixed to the sliding frame 33, and the electric push frame 35 controls the pressing brush b34 to move up and down, so that the pressing brush b34 guides the silicon steel to be immersed in the deacidification tank 31.

[0048] Add cleaning liquid into the deacidification tank 31, and after the end of the silicon steel passes through the guide rollers a7 and b9 on the two groups of movable frames 6, pass the end of the silicon steel through the guide brush b32 and the pressing brush b34, and finally fix the end of the silicon steel on the cylinder core after bypassing the pressing brush b34; start the electric push frame 35 to move the pressing brush b34 downward, and the pressing brush b34 presses the silicon steel down into the deacidification tank 31, so that the cleaning liquid removes the residual acid on the silicon steel. The silicon steel after deacidification can not only reduce the impact of the acid remaining on the silicon steel, but also enable personnel to operate the subsequent treatment of the silicon steel more safely and conveniently; while the silicon steel is being moved, the guide brush b32 and the pressing brush b34 rotate to assist the cleaning liquid to better remove the acid and improve the deacidification effect.

[0049] The pickling method using the pickling device comprises the following steps:

[0050] S1, remove the reel 14, put the core on the reel 14 and fix it, put the reel 14 back on the support frame b13, make the two gears 16 mesh, and place the silicon steel coil on the support frame a12;

[0051] S2, take out the end of the silicon steel coil, pass it through the guide brush a27 and the pressing brush a29, the guide roller a7 and the guide roller b9 on the two sets of movable frames 6, and the guide brush b32 and the pressing brush b34, and finally fix it on the cylinder core;

[0052] S3, start the pump body 25, make the nozzle 24 spray water, and the guide brush a27 and the pressing brush a29 cooperate to pre-decontaminate the silicon steel;

[0053] S4, start the motor a4, control the guide roller b9 to rotate relative to the guide roller a7, and guide the silicon steel downward into the pickling tank 1. During the process, the silicon steel coil rotates and continuously releases the silicon steel;

[0054] S5, start the motor b15, control the winding shaft 14 to rotate, and the silicon steel moves by the winding silicon steel control, and at the same time the transmission belt 21 and the transmission wheel 20 drive and control the rotation of the shifting roller 19 to stir the acid solution and shift the silicon steel;

[0055] S6, start the electric push frame 35, control the pressing brush b34 to guide the silicon steel downward, so that the silicon steel is immersed in the cleaning liquid in the deacidification tank 31 for deacidification treatment;

[0056] S7. After the silicon steel has been pre-cleaned, pickled and deacidified from the left side, it is rolled up on the drum core. After all the silicon steel is recovered on the drum core, the silicon steel and the drum core are removed from the winding shaft 14 for collection.
