Description
Technical Field
[0001] This application relates to the field of stainless steel plate pickling, and more specifically, to a pickling equipment for the production of high-strength stainless steel plates. Background Technology
[0002] High-strength stainless steel is a special type of steel made by optimizing alloy composition (such as adding elements like chromium, nickel, and molybdenum) and heat treatment processes. It combines the corrosion resistance, high-temperature resistance, and significantly improved mechanical strength of stainless steel.
[0003] After the stainless steel plate is produced, it needs to be pickled in a pickling tank to remove oxides and other substances from the surface of the stainless steel plate. When using it, the stainless steel plate is placed on a perforated plate and then immersed in the pickling tank. In order to make the bottom of the steel plate in contact with the acid solution, the position of the steel plate needs to be moved. However, due to the friction between the steel plate and the perforated plate, it is not convenient to move the position of the steel plate.
[0004] Chinese patent application CN202420952283.9 discloses a stainless steel plate pickling device, including a pickling tank and a mounting plate. A first cylinder is fixedly mounted on the bottom of the mounting plate, a vertical rod is fixedly mounted on the bottom end of the piston rod of the first cylinder, a connecting plate is fixedly mounted on the bottom end of the vertical rod, connecting rods are fixedly mounted at the four corners of the bottom of the connecting plate, and perforated plates are fixedly mounted on the bottom ends of the connecting rods. A stainless steel plate is placed on the top of the perforated plate. This patent provides through holes on both the left and right sides of the connecting plate, with rotating rods hinged in the through holes. Support wheels are rotatably connected to the holes of the perforated plate via pins. The rotating rods facilitate the movement of the steel plate, and the support wheels support the steel plate. At the same time, a certain gap exists between the perforated plate and the steel plate, and when moving the steel plate, the sliding of the steel plate is changed to rolling, thereby facilitating the movement of the steel plate and improving the pickling efficiency.
[0005] The above solution has the following shortcomings: After the stainless steel plate is pickled, the acid solution will adhere to the surface of the steel plate and is not easy to clean after pickling. Directly conveying it through the conveyor belt will easily corrode the conveyor belt, thereby reducing the service life of the conveyor belt. At the same time, the acid solution dripping onto the ground can easily pollute the working environment. Utility Model Content
[0006] To overcome the above shortcomings, this application provides a pickling equipment for the production of high-strength stainless steel plates, which aims to improve the problem that after the stainless steel plates are pickled, the acidic solution will adhere to the surface of the steel plates, making it difficult to clean after pickling. Directly conveying the solution through the conveyor belt will easily corrode the conveyor belt, thereby reducing its service life.

[0030] Please see Figure 1 This application provides a pickling device for producing high-strength stainless steel plates, including a pickling structure 10 and a cleaning structure 20.
[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The pickling structure 10 includes a housing 110, a pickling tank 120, a cleaning tank 130, and a rotating assembly 140. The housing 110 is provided with a pickling tank 120 and a cleaning tank 130. The rotating assembly 140 is located on one side of the housing 110. The bottom of the cleaning tank 130 is cleaned. Both the pickling tank 120 and the cleaning tank 130 are connected to a drain pipe, and a valve is installed on the drain pipe.
[0032] In its specific configuration, the rotating assembly 140 includes two first electric push rods 141, a circular plate 142, a servo motor 143, a rotating shaft 144, a rotating plate 145, two connecting rods 146, a fixing frame 147, and two L-shaped placement rods 148.

The two L-shaped placement rods 148 provide convenient support for the stainless steel plate.
[0033] In the specific setup, the fixing frame 147 and the two L-shaped placement rods 148 are all tilted. By tilting the fixing frame 147 and the two L-shaped placement rods 148, it is easy to prevent the placed stainless steel plate from falling off, and at the same time, it is easy to accelerate the flow of residual liquid from the surface of the stainless steel plate by gravity, which is convenient for subsequent cleaning.

A push plate 153 is fixedly connected to one side of the slide rod 152 and passes through the fixed frame 147. The arrangement of the two third electric push rods 151, the slide rod 152, and the push plate 153 makes it easy to push out the cleaned stainless steel plate and place it on the roller conveyor belt 160 for easy unloading.

The air outlet pipe 173 is connected to the hot air blower 172. Both branch pipes 174 are connected to the air outlet pipe 173. The two branch pipes 174 are arranged opposite to each other on both sides of the inner wall of the connecting frame 171. Several second nozzles 175 are evenly connected to the two branch pipes 174. The setup of the connecting frame 171, the hot air blower 172, the air outlet pipe 173, the two branch pipes 174, and the second nozzle 175 facilitates the drying of the cleaned stainless steel plate.
[0037] Please see Figure 1 , Figure 3 and Figure 4 The cleaning structure 20 includes a drive assembly 210, a support rod 220, a water inlet pipe 230, a hose 240, a support frame 250, a U-shaped pipe 260, and a first nozzle 270. The drive assembly 210 is disposed in the cleaning tank 130. The support frame 250 is connected to the drive assembly 210. The support rod 220 is fixedly connected to the housing 110. The water inlet pipe 230 is fixedly connected to the support rod 220. The two ends of the hose 240 are respectively connected to the water inlet pipe 230 and the U-shaped pipe 260. The U-shaped pipe 260 is fixedly connected to the support frame 250. Several first nozzles 270 are evenly connected to the U-shaped pipe 260. An external water pump draws water into the water inlet pipe 230.
[0038] In a specific configuration, the drive assembly 210 includes two second electric push rods 211 and a slider 212. The two second electric push rods 211 are installed opposite each other in the cleaning tank 130. The movable ends of the two second electric push rods 211 are fixedly connected to the sliders 212. The sliders 212 are slidably connected to the housing 110. The support frame 250 is fixedly connected to the sliders 212. The arrangement of the two second electric push rods 211 and the sliders 212 facilitates the reciprocating cleaning of the first nozzle 270 after acid washing of the stainless steel plate, thereby improving the cleaning effect.
[0039] The working principle of this pickling equipment for producing high-strength stainless steel plates is as follows: When using the pickling equipment, the stainless steel plates to be pickled are placed on two L-shaped placement rods 148 within an inclined fixed frame 147. At this time, the other fixed frame 147 already contains pickled stainless steel plates. Two first electric push rods 141 are synchronously driven, causing the circular plate 142 and the connected rotating plate 145 to rise as a whole, detaching the two sets of stainless steel plates from the pickling tank 120 and the cleaning tank 130. A servo motor 143 drives the rotating shaft 144 to rotate the rotating plate 145, causing the two sets of fixed frames 147 to interchange positions. The first electric push rods 141 then descend, allowing the two sets of stainless steel plates to enter the pickling tank 120 and the cleaning tank 130 respectively. The stainless steel plates to be pickled then undergo pickling. Two second electric push rods 211 drive the slider 212 and support frame 250 to move back and forth. An external water pump draws water into the inlet pipe 230, which then enters the first nozzle 270 through the hose 240. The first nozzle 270 on the U-shaped pipe 260 rinses the pickled stainless steel plate. After cleaning, the third electric push rod 151 drives the slide rod 152 and push plate 153 to move, pushing the cleaned stainless steel plate to the roller conveyor belt 160. The roller conveyor belt 160 transports the plate and blows hot air from the outlet pipe 173, two branch pipes 174 and the second nozzle 175 through the hot air blower 172 to dry the sides of the stainless steel plate. At this time, a new stainless steel plate to be pickled is placed on two L-shaped placement rods 148, and the servo motor 143 reverses to load the next batch, realizing cyclical production.
[0040] It should be noted that the specific models and specifications of the first electric push rod 141, servo motor 143, third electric push rod 151, roller conveyor belt 160, hot air blower 172 and second electric push rod 211 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0041] The power supply and operating principle of the first electric push rod 141, servo motor 143, third electric push rod 151, roller conveyor belt 160, hot air blower 172, and second electric push rod 211 are clear to those skilled in the art and will not be described in detail here.
[0042] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
