Description

Technical Field

[0001] This utility model belongs to the field of steel rolling technology, specifically a surface impurity pre-washing and removal mechanism for steel rolling pickling. Background Technology

[0002] Steel rolling is a pressure processing method in which steel ingots are hot-rolled or cold-rolled between two rotating pressure rollers to form steel plates of a specified thickness. After the steel rolling is completed, in order to improve the surface quality of the steel and remove the oxide scale and rust on the surface, the surface of the steel needs to be pickled.

[0003] Among them, a search revealed application number CN201920188628.7, a novel surface cleaning device for cold-rolled steel sheets. This novel surface cleaning device for cold-rolled steel sheets features a first flip shaft, a second flip shaft, a drive shaft, a guide shaft, a distance sensor, and a PLC controller. The drive shaft and guide shaft work together to move the cold-rolled steel sheet, avoiding uneven cleaning caused by manual movement. The first flip shaft, second flip shaft, and cleaning water nozzles work together to achieve simultaneous cleaning of both sides of the cold-rolled steel sheet, resulting in good cleaning effect and high efficiency. However, its shortcomings are as follows:

[0004] When workers use this new type of surface cleaning device for cold-rolled steel plates to clean impurities on the surface of the steel plates, the cold-rolled steel plates are pushed in from the inlet. As the cold-rolled steel plates pass between the first and second flipping shafts, both sides are cleaned simultaneously. When the cold-rolled steel plates reach the cleaning water nozzles, the cleaning water washes away the emulsion containing stains from the cold-rolled steel plates. However, when cleaning impurities on the surface of the steel plates, because the cleaning water nozzles are fixed in position and cannot move freely, some parts of the steel plates outside the cleaning range of the cleaning water nozzles will not be cleaned, resulting in a poor cleaning effect on the surface of the steel plates.

[0022] In this utility model:

[0023] Example 1: Refer to Figure 1-5 A surface impurity pre-washing and removal mechanism for steel rolling pickling includes a support frame A1, a fixed frame 101, a pickling tank 102, a cleaning tank 103, a screw slide rail A104, a sliding frame A105, a hydraulic rod 106, a clamping frame 107, an electric telescopic rod 108, a pressure plate 109, a water pump A2, a drainage trough A201, a drainage trough B3, a valve 301, and a water guide frame 5.

The cleaning tank 103 is equipped with a swing cleaning mechanism that can efficiently clean impurities on the surface of the rolled steel. The cleaning tank 103 is equipped with a flow guiding flushing mechanism that can efficiently rinse and clean the rolled steel. The drainage trough B3 is equipped with a shaking impurity filtration mechanism that can circulate and filter impurities in the water.

[0024] Reference Figure 1 , 2 4, 5, further, the swing cleaning mechanism is composed of a screw slide rail B4, a sliding frame B401, a telescopic rod B402, a support plate 403, a servo motor B404, an eccentric wheel B405, an electric cleaning roller 406 and a steel wire brush 407.

[0025] On both sides of the rear of the inner wall of the cleaning tank 103, a screw rod slide rail B4 is fixedly installed. In front of the screw rod slide rail B4, a sliding frame B401 is slidably arranged through a slider. On both sides of the inner wall of the sliding frame B401, a telescopic rod B402 is fixedly installed, and a spring is arranged in a matching manner on the outer side of the telescopic rod B402.

On the side of the inner wall of the sliding frame B401, a servo motor B404 is fixedly installed. The servo motor B404 is connected with an eccentric wheel B405 through an output shaft. When the staff needs to pre-clean the easily cleaned impurities on the surface of the rolled steel plate produced before pickling treatment, they carry several rolled steel plates to the cleaning site. After placing one of the rolled steel plates on the surface of the clamping frame 107, they control the electric telescopic rod 108 to lower the pressing plate 109 to contact the upper part of the rolled steel plate and clamp the rolled steel plate between the clamping frame 107 and the pressing plate 109. Then, they control the hydraulic rod 106 to lower the rolled steel plate into the cleaning tank 103. After the staff pours clean water into the cleaning tank 103 to submerge the rolled steel plate, the staff then controls the two screw rod slide rails B4 to drive the sliding frame B401 to move left and right repeatedly through the slider,带动两对电动清刷辊406反复左右移动,并由工作人员打开电动清刷辊406配套的伺服电机带动电动清刷辊406向着同一方向,带动外圈钢丝毛刷407转动,使钢丝毛刷407在轧钢板表面反复刮动清刷的同时,再打开伺服电机B404带动偏心轮B405快速转动,不断击打支撑板403通过伸缩杆B402和外侧弹簧反复伸缩,带动支撑板403和电动清刷辊406快速左右摆动,使不断移动的电动清刷辊406快速摆动,对轧钢板表面进行高效清刷处理,并在清刷完毕后,工作人员将轧钢板松开并进行位移,使遮挡部分露出到清理范围内后再次进行表面杂质清理,提高对轧钢板表面杂质进行高效清刷处理的效果。

[0026] Refer to Figure 2 、 3 , further, the shaking impurity filtering mechanism is composed of a support frame B302, a telescopic rod A303, a filter mesh frame 304, a servo motor A305, an eccentric wheel A306, a drainage tank C501, a water pump B502 and a water spray head 503;

[0027] It should be noted that there seems to be some garbled or unclear parts in the original text (such as "带动两对电动清刷辊406反复左右移动,并由工作人员打开电动清刷辊406配套的伺服电机带动电动清刷辊406向着同一方向,带动外圈钢丝毛刷4) which may affect the accuracy of the overall translation. You may want to check and correct the original text for a more accurate translation result.A support frame B302 is bolted to the lower part of the drainage trough B3. Telescopic rods A303 are fixedly installed on the upper and lower sides of both sides of the inner wall of the support frame B302, and springs are fitted on the outer sides of the telescopic rods A303. A filter screen frame 304 is fixedly installed between the sides of the ends of the telescopic rods A303, and the lower part of the filter screen frame 304 is arc-shaped. A servo motor A305 is fixedly installed on the inner side of the support frame B302. The servo motor A305 is connected to an eccentric wheel A306 through an output shaft. A drainage trough C501 is embedded in the lower part of the inner wall of the water frame 5. A water pump B502 is installed inside the lower part of the water guide frame 5. Several water nozzles 503 are embedded in the side of the inner wall of the cleaning tank 103, arranged in a front-to-back row. The drainage trough C501, water pump B502 and water nozzles 503 are connected by a water guide pipe. When the surface of the rolled steel plate is cleaned by the outer ring wire brush 407 of the repeatedly moving and swinging electric cleaning roller 406, impurities on the surface of the rolled steel plate will be removed. As the water falls into the water, the operator opens valve 301 to drain the water from the cleaning tank 103 through the drain trough B3 and through the arc-shaped filter screen 304 in the support frame B302. At the same time, the operator turns on servo motor A305 to drive eccentric wheel A306 to rotate rapidly, continuously striking the filter screen 304. Through the telescopic rod A303 and the outer spring, the filter screen 304 swings at high frequency, allowing water to pass through the filter screen 304. While blocking impurities in the water, the shaking of the filter screen 304 throws impurities to both sides and gathers them, preventing impurities from clogging the filter screen 304. This efficiently filters a large amount of water, and the filtered water falls into the water guide frame 5. At the same time, the operator turns on water pump B502 to suck the filtered water into the drain trough C501 and spray it back into the cleaning tank 103 through the water guide pipe from the water nozzle 503. This circulates and filters the water in the cleaning tank 103, allowing the clean water to be used for a long time without frequent water changes, and improving the efficiency of filtering impurities in the clean water.

[0028] Reference Figure 2 , 3 Furthermore, the flow guiding and flushing mechanism consists of a servo motor C6, a rotating rod 601, a flow guide frame 602, and flow guide blades 603;

[0029] A servo motor C6 is fixedly installed on the inner wall of the cleaning tank 103. The servo motor C6 is connected to a rotating rod 601 via its output shaft. A guide frame 602 is fixedly installed around the outer ring of the rotating rod 601. Several guide frames 602 are arranged in a ring shape at equal intervals. Guide blades 603 are fixedly installed around the outer ring of the guide frame 602. Several guide blades 603 are arranged in an inclined, equidistant ring. While the surface of the rolled steel plate is being cleaned by the repeatedly moving and oscillating electric cleaning roller 406 and its outer ring of wire brushes 407, and the water in the cleaning tank 103 is circulating and filtered, the operator turns on the servo motor C6, causing the guide frame 602 around the rotating rod 601 to rotate rapidly in the water. This rotation causes the inclined guide blades 603 to rotate in the water. The guide blades 603 generate resistance in the water, propelling the water and creating flow, causing the circulating water to flow rapidly from right to left. The process involves using water flow to flush and clean impurities from the surface of the rolled steel plate. After the impurities are removed, the operator controls the screw slide rail B4 to move the electric cleaning roller 406 to both ends of the cleaning tank 103. Then, the operator controls the hydraulic rod 106 to lift the rolled steel plate and controls the screw slide rail A104 to move the rolled steel plate above the pickling tank 102. After that, the operator controls the hydraulic rod 106 to lower the rolled steel plate and immerse it in the strong acid liquid in the pickling tank 102 for final pickling treatment. Then, the operator controls the hydraulic rod 106 to lift the rolled steel plate again and controls the screw slide rail A104 to move the rolled steel plate to the other end. Then, the operator controls the hydraulic rod 106 to lower the rolled steel plate and controls the electric telescopic rod 108 to lift the pressure plate 109 to release the rolled steel plate. The clamping frame 107 is then moved back to its original position. The same process is then used to clean other rolled steel plates, improving the efficiency of the flushing and cleaning treatment of the rolled steel plates.

[0030] Reference Figure 1-5 Furthermore, the hydraulic rod 106 is electrically connected to an external power source via a matching hydraulic pump and a matching control panel, the electric cleaning roller 406 is electrically connected to an external power source via a matching servo motor and a matching control panel, and the lead screw slide rail A104, electric telescopic rod 108, water pump A2, valve 301, servo motor A305, lead screw slide rail B4, servo motor B404, water pump B502, and servo motor C6 are all electrically connected to an external power source via matching control panels.

[0031] Example 2:

[0032] like Figure 3 , 6As shown, in addition to the embodiment in which guide vanes 603 are fixedly installed on the outer ring of the guide frame 602, and there are several guide vanes 603 arranged in an inclined and equidistant manner, there is another embodiment in which guide vanes 603 are fixedly installed on the outer ring of the guide frame 602, and there are several guide vanes 603 arranged in an arc shape and equidistantly arranged. When the operator turns on the servo motor C6 to drive the outer ring of the guide frame 602 of the rotating rod 601 to rotate rapidly in the water, it drives the several arc-shaped guide vanes 603 on the outer ring to rotate in the water. The guide vanes 603 will generate greater resistance in the water, pushing the water to generate faster flow, making the circulating water flow more quickly from right to left, and making the water flow quickly flush and clean the impurities on the surface of the rolled steel plate. Compared with the first embodiment, the flushing and cleaning effect is better.

[0033] Working principle: First, before the produced rolled steel plates undergo pickling, the workers need to pre-clean the surface to remove easily removable impurities. Several rolled steel plates are brought to the cleaning area, and one plate is placed on the surface of the clamping frame 107. The electric telescopic rod 108 is then lowered to contact the pressure plate 109 above the rolled steel plate, clamping it between the clamping frame 107 and the pressure plate 109. Next, the hydraulic rod 106 is lowered to place the rolled steel plate into the cleaning tank 103. The workers then fill the cleaning tank 103 with clean water to submerge the rolled steel plate. Finally, the workers control two lead screw slides B4 to drive the sliding frame B401 to move left and right repeatedly, causing the two pairs of electric cleaning rollers 406 to move left and right repeatedly. The workers then activate the electric cleaning rollers 406. The servo motor drives the electric cleaning roller 406 in the same direction, causing the outer wire brush 407 to rotate. Simultaneously, the wire brush 407 repeatedly scrapes and cleans the surface of the rolled steel plate. At the same time, the servo motor B404 drives the eccentric wheel B405 to rotate rapidly, continuously striking the support plate 403. Through the telescopic rod B402 and the outer spring, the support plate 403 and the electric cleaning roller 406 swing rapidly left and right, allowing the continuously moving electric cleaning roller 406 to swing rapidly, effectively cleaning the surface of the rolled steel plate. Then, impurities on the surface of the rolled steel plate fall into the water. At this time, the operator opens the valve 301 to drain the water from the cleaning tank 103 into the drainage trough B3, which passes through the arc-shaped filter screen 304 inside the support frame B302. Simultaneously, the operator opens the servo motor... The servo motor A305 drives the eccentric wheel A306 to rotate rapidly, continuously striking the filter screen frame 304. Through the telescopic rod A303 and the outer spring, the filter screen frame 304 repeatedly extends and retracts, causing it to oscillate at high frequency. This allows water to pass through the filter screen frame 304, blocking impurities while simultaneously throwing them to the sides through the oscillation, preventing clogging. This efficient filtration of a large volume of water, along with the filtered water falling into the water guide frame 5, allows the operator to turn on the water pump B502, drawing the filtered water into the drain tank C501. Through the water guide pipe, the water is sprayed back into the cleaning tank 103 from the water nozzle 503, circulating and filtering the water in the cleaning tank 103. This ensures the clean water can be used for a long time without frequent water changes. Finally, the operator turns on... Servo motor C6 drives the rotating rod 601 and the outer ring guide frame 602 to rotate rapidly in the water, causing several inclined guide vanes 603 on the outer ring to rotate in the water. The guide vanes 603 generate resistance in the water, pushing the water to create fluidity, causing the circulating water to flow rapidly from right to left. This water flow washes and cleans impurities on the surface of the rolled steel plate. After the impurities are cleaned, the operator controls the screw slide rail B4 to move the electric cleaning roller 406 to both ends of the cleaning tank 103. Then, the operator controls the hydraulic rod 106 to lift the rolled steel plate and controls the screw slide rail A104 to move the rolled steel plate above the pickling tank 102. Finally, the operator controls the hydraulic rod 106 to lower the rolled steel plate into the strong acid liquid in the pickling tank 102 for the final pickling treatment of the rolled steel plate surface.The hydraulic rod 106 is controlled to lift the rolled steel plate. Then, the lead screw slide rail A104 is controlled to move the rolled steel plate to the other end. The hydraulic rod 106 is then controlled to lower the rolled steel plate. Next, the electric telescopic rod 108 is controlled to lift the pressure plate 109 to release the rolled steel plate. The clamping frame 107 is then moved back to its original position. The other rolled steel plates are then cleaned in the same manner.
