Description

Technical Field

[0001] The present invention relates to the technical field of steel plate pickling, and in particular to energy-saving steel plate pickling equipment and a method thereof for reducing mutual pollution. Background Art

[0002] Pickling steel plates involves immersing them in an acidic solution to clean and remove oxides. Pickling removes impurities such as rust, scale, and scale from the steel plate's surface, thereby improving the steel's surface quality and workability. Commonly used acids for pickling include hydrochloric acid, sulfuric acid, and dilute nitric acid, with the type and concentration of acid selected based on specific needs. After pickling, the steel plate undergoes water washing and rust-proofing treatment to prevent secondary oxidation. Pickling steel plates are widely used in industries such as automotive, shipping, railways, construction, home appliances, and metalworking.

[0003] For example, patent publication number CN210215556U discloses a strip pickling tank capable of reducing hydrochloric acid consumption. This device is suitable for industrial continuous hydrochloric acid pickling of strip steel, and can obtain strip steel with good cleaning effects on both the upper and lower surfaces, thereby improving the utilization efficiency of hydrochloric acid. However, during the pickling process, reactants will adhere to the surface of the steel, reducing the pickling effect. If the attachments are removed by friction, the steel may overturn due to uneven force, affecting the pickling efficiency.

[0004] Based on this, the present invention designs an energy-saving steel plate pickling equipment and method that reduces mutual contamination to solve the above problems. Summary of the Invention

[0020] The present application also provides a method for energy-saving steel plate pickling equipment that reduces mutual contamination, comprising the following steps:

[0021] Step 1: Align the end of the new material with the end of the previous material below the end connection mechanism, start the first motor to drive the screw to rotate, and the screw drives the movable table to move within the limit of the first slide rail, so that the movable table drives the seam welding device to weld the material seams;

[0022] Step 2: While the seam welding device is welding the seam, the movable table drives the grinding device and the seam welding device to move synchronously through the reciprocating plate to grind the weld seam after the material is welded; when the reciprocating plate and the connecting plate move, the sliding shaft moves in the slide groove of the reciprocating drive plate, pushing the reciprocating plate to move back and forth under the limiting action of the second slide rail, thereby driving the grinding device to move back and forth to grind the weld seam;

[0023] Step 3: The material is transported to the cleaning tank by the material guide device and immersed in the acid solution. The second motor drives the first transmission shaft to rotate. The first transmission shaft drives the second transmission shaft to rotate through the first transmission assembly, thereby driving the stirring fan to rotate. The stirring fan continuously stirs the acid solution to make the acid solution flow, ensuring that the concentration of the acid solution in each part of the cleaning tank is uniform.

[0024] Step 4: Start the third motor to drive the bidirectional screw to rotate. The bidirectional screw drives the L-plates on both sides to move closer to each other through the movable sleeve, so that the guide rollers on both sides clamp the material and roughly adjust the position of the overall guide rollers;

[0025] Step 5: Adjust the connecting plate by rotating the fine adjustment rod to change the position of the guide roller. After the adjustment is completed, the guide roller on this side is fixed in position to position the material and achieve fine adjustment of the guide roller. The guide roller of the floating splint drives the connecting plate to move under the limiting action of the L plate after being subjected to force, and the second floating spring and the second floating guide rod cooperate to buffer the force on the guide roller.

[0026] Step 6: The first transmission shaft drives the rotating shaft to rotate through the second transmission assembly, and the rotating shaft drives the grinding roller to grind the surface of the material to remove the reactants, and the spray device draws acid from the cleaning tank to spray the material to increase the pickling effect;

[0027] Step 7: Adjust the height of the adjustment plate by rotating the first floating guide rod. The sliding rod maintains the vertical movement of the adjustment plate, thereby adjusting the distance between the scraper and the main body, so that the scraper can be used for materials of different thicknesses. After being polished, the material is conveyed to the lower end of the scraper. The scraper scrapes off the attachments on the surface of the material. When encountering unevenness on the surface of the material, the material lifts up the scraper and moves vertically under the limiting action of the first floating guide rod. The first floating spring buffers the force of the scraper to achieve floating scraping.

[0028] Step 8: The material guide device transports the material to the subsequent cleaning tank in sequence, and repeats steps 3 to 7 to clean and neutralize the material to complete the pickling operation of the steel plate.

[0029] Beneficial effects

[0030] In the present invention, the ends of the new material and the previous material are aligned below the end connecting mechanism, and the end connecting mechanism drives the rolling welding device to weld the ends. At the same time, the end connecting mechanism drives the grinding device to grind the weld to prevent the protrusion of the weld from affecting the material transportation in subsequent processing; the material is transported to the cleaning tank by the material guiding device and immersed in the acid solution, and the uniform pickling mechanism is started to stir the acid solution in the cleaning tank to ensure that the concentration of the acid solution is uniform everywhere, so that the material is uniformly pickled in the cleaning tank; at the same time, the uniform pickling mechanism grinds the material that has completed pickling to remove the reactants on the surface of the material and enhance the pickling effect; the uniform pickling mechanism can achieve the effects of grinding the reactants on the surface of the material and stirring the acid solution through one power input, which greatly saves energy consumption; when the material is transported to the bottom of the bracket, the limiting mechanism clamps the two ends of the material to prevent the material from overturning due to uneven force during processing, thereby affecting the pickling process.

[0031] While the roll welding device is welding the material, the reciprocating plate drives the grinding device to move back and forth to grind the weld, greatly improving the grinding effect; the limit mechanism can be adjusted coarsely and finely, and is suitable for materials of various sizes; after the material leaves the acid solution and is ground, the floating scraping mechanism scrapes off the surface attachments to prevent the material from carrying contaminants from the previous cleaning tank to the next cleaning tank, avoiding mutual contamination of the cleaning tanks.

[0065] Example 2

[0066] Please refer to the instruction manual Figure 1-9 A method for reducing mutual contamination of energy-saving steel plate pickling equipment comprises the following steps:

[0067] Step 1: Align the end of the new material with the end of the previous material below the end connection mechanism 2, start the first motor 24 to drive the screw 23 to rotate, and the screw 23 drives the movable platform 25 to move within the limit of the first slide rail 22, so that the movable platform 25 drives the seam welding device 8 to weld the material seam;

[0068] Step 2: While the seam welding device 8 is welding the seam, the movable platform 25 drives the grinding device 9 and the seam welding device 8 to move synchronously through the reciprocating plate 27 to grind the weld seam after the materials are welded; when the reciprocating plate 27 and the connecting plate 28 move, the sliding shaft 29 moves in the slide groove of the reciprocating drive plate 210, pushing the reciprocating plate 27 to reciprocate under the limiting action of the second slide rail 26, thereby driving the reciprocating plate 27 to drive the grinding device 9 to reciprocate to grind the weld seam;

[0069] Step 3: The material is transported by the material guide device 7 to the cleaning tank 6 and immersed in the acid solution. The second motor 31 drives the first transmission shaft 32 to rotate. The first transmission shaft 32 drives the second transmission shaft 33 to rotate through the first transmission assembly 34, thereby driving the stirring fan 36 to rotate. The stirring fan 36 continuously stirs the acid solution to ensure that the acid solution is uniform in concentration throughout the cleaning tank 6.

[0070] Step 4: Start the third motor 51 to drive the bidirectional screw 52 to rotate. The bidirectional screw 52 drives the L-plates 54 on both sides to move closer to each other through the movable sleeve 53, so that the guide rollers 57 on both sides clamp the material, and the position of the entire guide roller 57 is roughly adjusted;

[0071] Step 5: Adjust the connecting plate 55 by rotating the fine adjustment rod 56 to change the position of the guide roller 57. After the adjustment is completed, the side guide roller 57 is fixed in position to position the material and achieve fine adjustment of the guide roller 57. The guide roller 57 of the floating clamp drives the connecting plate 55 to move under the limiting action of the L plate 54 after being subjected to force, and the second floating spring 58 and the second floating guide rod 59 cooperate to buffer the force on the guide roller 57.

[0072] Step 6: The first transmission shaft 32 drives the rotating shaft 37 to rotate through the second transmission assembly 35. The rotating shaft 37 drives the grinding roller 38 to grind the surface of the material to remove the reactants, and the spray device 39 draws acid from the cleaning tank 6 to spray the material to increase the pickling effect.

[0073] Step 7: The height of the adjustment plate 42 is adjusted by rotating the first floating guide rod 45. The slide rod 43 maintains the vertical movement of the adjustment plate 42, thereby adjusting the distance between the scraper 41 and the main body 1 so that the scraper 41 can be used for materials of different thicknesses. After being polished, the material is conveyed to the lower end of the scraper 41. The scraper 41 scrapes off the attachments on the surface of the material.
