Description

Technical Field

[0001] This utility model relates to the field of steel strip surface drying technology, specifically to a surface drying device for steel strips after cleaning. Background Technology

[0002] Steel strip, also known as strip steel, is a narrow and long steel plate made of carbon steel. In order to ensure the cleanliness of the steel strip surface, it needs to be cleaned. After cleaning, the surface of the steel strip will have residual moisture, which may contain cleaning agents, grease or other contaminants. If it is not dried in time, these residues may re-adhere to the surface of the steel strip, causing secondary pollution. Therefore, drying can ensure that the surface of the steel strip is dry and clean, which is conducive to the smooth progress of subsequent processing procedures such as rolling and welding.

[0003] Existing steel strip drying efficiency is low. For example, a steel strip drying device disclosed in patent CN207945906U effectively removes liquid from the surface of the steel strip through three steps: water blocking, drying, and water absorption. However, the water absorption roller, air outlet, and water blocking roller in this device can only work on one side of the steel strip. This means that the other side may not be sufficiently dried. In continuous production scenarios, this single-sided drying method may lead to a decrease in overall drying efficiency because additional time or equipment is needed to process the other side.

[0004] Therefore, it is necessary to invent a surface drying device for steel strips after cleaning to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a surface drying device for steel strips after cleaning, so as to solve the problem of low drying efficiency of steel strips in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a surface drying device for steel strip after cleaning, comprising a frame, a pretreatment box disposed above the frame, and mounting plates disposed at the upper and lower ends inside the pretreatment box. Two mounting plates are provided, one of which is fixedly installed at the lower part of the pretreatment box, and the other is disposed at the upper part of the pretreatment box. A cylinder is disposed on the top surface of the pretreatment box, and the output end of the cylinder is connected to the top surface of the mounting plate located above the pretreatment box. A sliding mechanism is disposed inside the mounting plate. The pretreatment box has a sliding groove at the contact position between the mounting plate and the slider. A scraper is provided on the slider. A connector is provided on the side wall of the mounting plate. A limit plate is hinged to the connector. A fixing bolt is connected through the limit plate and extends to the slider. A screw hole is provided at the contact position between the slider and the fixing bolt. A drying box is provided on one side of the pretreatment box. A lower air outlet is provided at the bottom of the drying box. An upper air outlet is provided at the top of the drying box. A hot air fan is provided inside the frame. An air supply pipe is connected between the hot air fan and the lower and upper air outlets.

[0007] Preferably, an unwinding reel is provided on one side of the frame and a winding reel is provided on the other side of the frame. The unwinding reel is used to place the steel strip roll to be processed, while the winding reel is used to collect the processed steel strip, thus realizing continuous feeding and unloading of the steel strip.

[0008] Preferably, four guide rollers are provided above the frame, and the four frames are located inside the pretreatment box. The guide rollers are used to guide the transmission path of the steel strip inside the pretreatment box, which can ensure that the steel strip moves smoothly and steadily inside the pretreatment box.

[0009] Preferably, there are two wiper blades, both made of silicone material, located at the upper and lower ends of the pretreatment box. A collection box is located below the wiper blades inside the frame. The wiper blades are used to remove water from the surface of the steel strip, ensuring that both the upper and lower surfaces of the steel strip are adequately wiped clean. The collection box can collect the water removed by the wiper blades from the steel strip.

[0010] Preferably, the slider and the groove are slidably connected, and the slider and the groove cooperate with each other. The slidable connection between the slider and the groove facilitates the disassembly and replacement of the wiper blade.

[0011] Preferably, the fixing bolt and the screw hole are connected by threads, and the outer thread of the fixing bolt and the inner thread of the screw hole are matched. The threaded connection between the fixing bolt and the screw hole is used to fix the position of the slider and the wiper blade, which can ensure that the slider and the wiper blade remain stable on the mounting plate.

[0012] Preferably, a conveyor roller is rotatably connected to the inner wall of the drying chamber. Multiple conveyor rollers are arranged in an equidistant and uniform array. The conveyor rollers are used to guide the transmission path of the steel belt inside the drying chamber and ensure that the steel belt moves smoothly during the drying process.

[0013] Preferably, a lower air outlet is provided below the conveyor roller, and an upper air outlet is provided above the conveyor roller. Multiple lower and upper air outlets are provided, and the air inlets of the multiple lower and upper air outlets are connected to the air outlets of the hot air blower through air supply pipes. This can ensure that the hot air is blown evenly and fully onto the upper and lower surfaces of the steel strip, thereby improving drying efficiency and quality.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model, by setting a pretreatment box and internal upper and lower scraper blades, uses a cylinder to drive the upper mounting plate and scraper blades to move up and down, which can flexibly adapt to steel strips of different thicknesses, ensuring that the moisture on the upper and lower surfaces of the steel strip is thoroughly scraped off. The silicone scraper blades are not only wear-resistant but also will not scratch the surface of the steel strip, ensuring the surface quality of the treated steel strip. Furthermore, the scraper blades are slidably installed in the grooves on the mounting plate by a slider and can be fixed in position by the threaded connection between the fixing bolts and the screw holes, thus facilitating the disassembly and replacement of the scraper blades.

[0016] 2. This utility model adopts a configuration of two scraper blades and two air outlets (lower air outlet and upper air outlet). The two scraper blades are located at the upper and lower ends of the pretreatment box, respectively. This design can treat the upper and lower surfaces of the steel belt at the same time, ensuring that the steel belt can be effectively scraped off no matter which side comes into contact with water or other liquids during the transmission process. By setting the lower and upper air outlets, hot air can be blown from both sides of the steel belt at the same time to achieve uniform drying on both sides, making the entire processing process smoother and more efficient.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-6 The device shown is a surface drying apparatus for steel strip after cleaning. It includes a frame 1, with an unwinding roller 2 on one side above the frame 1 and a take-up roller 3 on the other side. A pretreatment box 5 is located above the frame 1, and four guide rollers 4 are also located above the frame 1. The four frames 1 are located inside the pretreatment box 5. Mounting plates 6 are located at both the upper and lower ends inside the pretreatment box 5. Two mounting plates 6 are provided; one is fixedly installed at the lower part of the pretreatment box 5, and the other is located at the upper part. A cylinder 7 is located on the top surface of the pretreatment box 5, and the output end of the cylinder 7 is connected to the top surface of the mounting plate 6 located above the pretreatment box 5. The mounting plate 6 is connected to the sliding block 9 inside. A groove 10 is provided at the contact position between the mounting plate 6 and the sliding block 9. A scraper 8 is provided on the sliding block 9. A connector 11 is provided on the side wall of the mounting plate 6. A limiting plate 12 is hinged to the connector 11. A fixing bolt 13 is connected through the limiting plate 12 and extends to the sliding block 9. A screw hole 14 is provided at the contact position between the sliding block 9 and the fixing bolt 13. A drying box 15 is provided on one side of the pretreatment box 5. A lower air outlet 19 is provided at the bottom of the drying box 15. An upper air outlet 20 is provided at the top of the drying box 15. A hot air blower 17 is provided inside the frame 1. An air supply pipe 18 is connected between the hot air blower 17 and the lower air outlet 19 and the upper air outlet 20.

[0027] There are two wiper blades 8, which are made of silicone. The two wiper blades 8 are located at the upper and lower ends of the pretreatment box 5. A collection box 21 is located below the wiper blades 8 and is located inside the frame 1. The slider 9 and the slide groove 10 are slidably connected and cooperate with each other. The fixing bolt 13 and the screw hole 14 are threadedly connected and cooperate with each other.

[0028] The pretreatment box 5 is used to initially remove moisture from the surface of the cleaned steel strip. Two silicone squeegees 8 can simultaneously remove moisture from both the upper and lower surfaces of the steel strip. To collect the scraped moisture, the collection box 21 can receive and store the water dripping from the squeegees 8. The height of the squeegees 8 inside the pretreatment box 5 can be adjusted by two cylinders 7, allowing it to be adjusted according to the thickness of the steel strip. This ensures that the moisture on the upper and lower surfaces of the steel strip is effectively removed, improving the squeegee effect. Furthermore, the sliding connection between the slider 9 and the slide groove 10, as well as the threaded connection between the fixing bolt 13 and the screw hole 14, allows for easy disassembly and assembly of the squeegees 8, enabling regular replacement and maintenance of the squeegees 8.

[0029] A conveyor roller 16 is rotatably connected to the inner wall of the drying oven 15. Multiple conveyor rollers 16 are arranged in an evenly spaced array. A lower air outlet 19 is provided below the conveyor roller 16, and an upper air outlet 20 is provided above the conveyor roller 16. Multiple lower air outlets 19 and upper air outlets 20 are provided. The air inlet ends of multiple lower air outlets 19 and upper air outlets 20 are connected to the air outlet end of the hot air blower 17 through an air supply pipe 18.

[0030] The multiple conveyor rollers 16 ensure smooth transmission of the steel strip during the drying process inside the drying chamber 15. The double-sided drying design of the lower air outlet 19 and the upper air outlet 20, along with the cooperation of the hot air blower 17 and the air supply pipe 18, ensures that the hot air is evenly and fully blown onto the upper and lower surfaces of the steel strip, thereby effectively improving drying efficiency and quality.

[0031] Working principle of this utility model:

[0032] Refer to the instruction manual appendix Figure 1-4When using this utility model, first install the cleaned steel strip on the unwinding wheel 2, and ensure that the steel strip can pass smoothly through the pretreatment box 5 and the drying box 15, and finally wind onto the take-up wheel 3. Then turn on the hot air blower 17 and preheat for a period of time. When the steel strip enters the pretreatment box 5, adjust the height of the mounting plate 6 located above the inside of the pretreatment box 5 according to the thickness of the steel strip, thereby adjusting the distance between the upper and lower scraper blades 8. Thus, the upper and lower scraper blades 8 are in close contact with the surface of the steel strip, and at the same time scrape the upper and lower surfaces of the steel strip to remove residual water. The scraped water can fall into the collection box 21 for centralized collection. When the scraper blades 8 need to be disassembled and replaced after long-term use, the fixing bolts 13 can be manually loosened so that the fixing bolts 13 are disengaged from the screw holes 14, and then the scraper blades 8 can be slid off.

[0033] Refer to the instruction manual appendix Figure 5-6 When using this utility model, the steel strip after being treated with water enters the drying box 15 and is smoothly transported by multiple conveying rollers 16. In the drying box 15, hot air is blown out from the lower air outlet 19 and the upper air outlet 20 at the same time to dry the upper and lower surfaces of the steel strip. The hot air is provided by the hot air blower 17 and is transported to the lower air outlet 19 and the upper air outlet 20 through the air supply pipe 18. After the steel strip has been completely dried in the drying box 15, it can be wound on the winding wheel 3 for winding.
