[0001] This utility model relates to the field of pickling technology for cold-rolled steel sheets, specifically to a pickling device for cold-rolled steel sheets that can be thoroughly cleaned. Background Technology

[0002] Cold-rolled plain steel plate is a steel plate produced by the cold rolling process. Cold rolling refers to the reprocessing of hot-rolled plate at room temperature. The steel plate is thinned by rolling mill and its surface quality and flatness are improved. Pickling solution is used to remove oxide scale, rust and other impurities from the surface of cold-rolled plain steel plate. The aim is to improve the surface quality of the plate, improve the performance of subsequent processing, and ensure that the appearance and mechanical properties of the final product meet the standard requirements.

[0003] Existing pickling equipment for cold-rolled steel sheets generally suffers from the inability to effectively pickle the entire surface of the sheets. Due to design limitations of traditional pickling equipment, the contact between the pickling solution and the sheet surface is insufficient and uneven, resulting in a significant amount of oxide scale, rust, and other impurities remaining on the surface of the cold-rolled steel sheets. These incompletely removed impurities not only affect the appearance quality of the sheets but may also lead to defects in subsequent processing, affecting the quality and service life of the finished product. Based on this, a comprehensive cold-rolled steel sheet pickling device is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1The cold-rolled steel plate pickling device that can be thoroughly cleaned in this embodiment includes a pickling tank 1. A bearing block 2 is fixed on one side of the left and right side walls of the inner cavity of the pickling tank 1. A brushing mechanism 3 for cleaning the cold-rolled steel plate is provided on the front and back sides of the left and right ends of the upper surface of the pickling tank 1. A spraying mechanism 4 is provided on the top of the front and back side walls of the inner cavity of the pickling tank 1.

[0023] In this embodiment, the pickling tank 1 is a cuboid with a hollow interior and a missing upper surface.

[0024] Please see Figures 2 to 3 To thoroughly clean the cold-rolled steel sheet, the brushing mechanism 3 in this embodiment includes fixed blocks 301 on the left and right ends and front and rear sides of the upper surface of the pickling tank 1. A lead screw 302 is rotatably connected between opposite sides of the left and right ends of the rear fixed blocks 301 via bearings. A sliding plate 303 is threaded onto the outer surface of the lead screw 302. A fixed box 304 is fixed to the lower surface of the sliding plate 303. An electric push rod 305 is fixed to the inner top wall of the fixed box 304. By starting the drive motor, the output shaft of the drive motor rotates, causing the lead screw 302 to rotate. The rotation of the lead screw 302 causes the sliding plate 302 threaded onto its surface to rotate. 03 Move to the right, the movement of sliding plate 303 drives the fixed box 304 to move, thereby allowing the upper brush plate 306 and lower brush plate 307 to move, so as to brush the upper and lower surfaces of the cold-rolled plate. The piston rod of electric push rod 305 passes through the inner bottom wall of fixed box 304 and extends to the lower surface of fixed box 304 and fixes the upper brush plate 306. The lower brush plate 307 is provided on the lower side of the upper brush plate 306. Start electric push rod 305. After electric push rod 305 moves to a suitable position, place both ends of cold-rolled plate on two bearing blocks 2. At this time, cold-rolled plate is located on the opposite side of upper brush plate 306 and lower brush plate 307.

[0025] Mounting blocks 308 are fixed on both the front and rear sides of the upper brush plate 306 and the lower brush plate 307. The upper surface of the upper front mounting block 308 is rotatably connected by a bearing to a screw 309 that extends through and to the lower side of the lower front mounting block 308. The upper surface of the upper rear mounting block 308 is fixed with a limiting rod 310 that extends through and to the lower side of the lower rear mounting block 308. When the screw 309 is rotated, the rotation of the screw 309 causes the two lower mounting blocks 308 and the lower brush plate 307 to move upward under the action of the limiting rod 310, so that the gap between the lower brush plate 307 and the upper brush plate 306 is reduced and they are in contact with the upper and lower surfaces of the cold-rolled plain plate.

[0026] In this embodiment, a sliding rod is fixed between the opposite sides of the front left and right fixed blocks 301. The sliding plate 303 is slidably connected to the sliding rod. The sliding plate 303 moves horizontally and linearly between the lead screw 302 and the sliding rod. The sliding rod is used to limit the movement of the sliding plate 303 so that the sliding plate 303 can only move in a straight line.

[0027] In addition, both the upper brush plate 306 and the lower brush plate 307 are made of corrosion-resistant and wear-resistant nylon or steel wire materials, which can effectively remove oxide scale and impurities without scratching the surface of cold-rolled plain plates.

[0028] The lower mounting block 308 is threadedly connected to the screw 309, and the lower mounting block 308 is slidably connected to the limiting rod 310. The length and width of the upper brush plate 306 and the lower brush plate 307 are smaller than the length and width of the inner cavity of the pickling tank 1, respectively. A drive motor is fixed on the right side of the rear right end fixing block 301. The output shaft of the drive motor passes through and extends to the left side of the rear right end fixing block 301 and is fixed to the lead screw 302.

[0029] It should be noted that the pickling equipment can be flexibly adjusted according to the size and thickness of the cold-rolled steel sheet to adapt to different specifications of products, which enhances the versatility and applicability of the pickling equipment. Furthermore, the use of upper and lower brush plates 307 greatly improves the pickling efficiency of the cold-rolled steel sheet, enabling effective and comprehensive cleaning of the cold-rolled steel sheet.

[0030] Please see Figure 4 To provide a water source, the spraying mechanism 4 in this embodiment includes hollow pipes 401 fixed to the top of opposite sides of the front and rear walls of the pickling tank 1. Multiple rotating nozzles 402 are connected to opposite sides of the hollow pipes 401. A water pump 403 is fixed to the top of the left side of the pickling tank 1. When pickling the cold-rolled steel sheet, the angle of the rotating nozzles 402 is adjusted to ensure that the surface of the cold-rolled steel sheet is sprayed evenly. The inlet of the water pump 403 is connected to a pipe, and the outlet of the water pump 403 is connected to a two-way pipe 404. Both ends of 04 penetrate the pickling tank 1 and extend into the inner cavity of the pickling tank 1, and are respectively connected to two hollow tubes 401. The water pump 403 is started, and the water inlet of the water pump 403 draws the pickling liquid into the inner cavity of the one-to-two pipe 404 through the pipe. Then, the pickling liquid entering the one-to-two pipe 404 is guided into the hollow tubes 401 on the front and rear sides respectively. Finally, the pickling liquid in the hollow tube 401 can be sprayed out through multiple rotating nozzles 402 to spray the cold-rolled plain plate. After the pickling liquid in the inner cavity of the pickling tank 1 has submerged the cold-rolled plain plate, the water pump 403 can be turned off.

[0031] In this embodiment, multiple rotating nozzles 402 are evenly distributed on opposite sides of the hollow tubes 401 on the front and rear sides. Water outlet pipes are connected to the bottom of both sides of the pickling tank 1, and a control valve is fixed at the other end of the water outlet pipe.

[0032] It should be noted that the combined action of the brushing mechanism 3 and the spraying mechanism 4 enables all-round cleaning of the surface of the cold-rolled steel plate, ensuring that the oxide scale and impurities are thoroughly removed, thereby improving the surface quality and processing performance of the plate. The design of the drive motor and electric push rod 305 allows the brush to automatically adjust its position and force, which, together with the uniform spraying of the rotating nozzle 402, greatly improves the pickling efficiency.

[0033] The working principle of the above embodiments is as follows:

[0034] (1) When pickling cold-rolled steel sheet, adjust the angle of the rotating nozzle 402 to ensure that the surface of the cold-rolled steel sheet is sprayed. Connect the water inlet of the water pump 403 to the pipe and place the other end of the pipe into the tank containing the pickling solution. Start the water pump 403. The water inlet of the water pump 403 draws the pickling solution into the inner cavity of the one-to-two pipe 404 through the pipe. Then, the pickling solution entering the one-to-two pipe 404 is guided into the hollow pipes 401 on the front and back sides respectively. Finally, the pickling solution in the hollow pipe 401 can be sprayed out through multiple rotating nozzles 402 to spray the cold-rolled steel sheet. After the pickling solution in the inner cavity of the pickling tank 1 has submerged the cold-rolled steel sheet, the water pump 403 can be turned off.

[0035] (2) Start the electric push rod 305. After the electric push rod 305 moves to the appropriate position, place both ends of the cold-rolled sheet on the two bearing blocks 2. At this time, the cold-rolled sheet is located on the opposite side of the upper brush plate 306 and the lower brush plate 307. Then rotate the screw 309. The rotation of the screw 309 drives the two mounting blocks 308 at the lower end and the lower brush plate 307 to move upward under the action of the limit rod 310, so that the gap between the lower brush plate 307 and the upper brush plate 306 is reduced and they are in contact with the upper and lower surfaces of the cold-rolled sheet. Then start the drive motor. The output shaft of the drive motor rotates. The lead screw 302 is rotated, causing the sliding plate 303 threaded onto its surface to move to the right. The movement of the sliding plate 303 moves the fixed box 304, thereby moving the upper brush plate 306 and the lower brush plate 307 to brush the upper and lower surfaces of the cold-rolled steel plate. After brushing, the pickling solution can be allowed to flow into the filter box for solid-liquid separation by opening the control valve on the left. Then, the water inlet pipe of the water pump 403 is connected to the water source, and the cold-rolled steel plate can be rinsed by multiple rotating nozzles 402. Finally, it is sent into the drying oven for drying.
