Description

Technical Field

[0001] This utility model relates to the field of steel strip pickling technology, specifically a temperature detection device for steel strip pickling tanks. Background Technology

[0002] Pickling is a crucial process in strip steel production, primarily aimed at removing iron oxide scale from the strip's surface. The pickling process typically takes place in a pickling tank. After the strip enters the tank, hydrochloric acid gradually corrodes or loosens the iron oxide scale, making it easier to clean in subsequent processes. To improve pickling efficiency, the acid solution is usually heated to accelerate the reaction. Current technology uses temperature sensors within the pickling tank to monitor the acid temperature in real time for precise temperature control. However, the pickling tank is quite long, and the heating elements do not completely cover the entire area. Therefore, temperatures may vary at different locations within the tank, and fixed-position temperature sensors can only detect a small area, making it difficult to fully understand the temperature conditions at every point in the tank, resulting in decreased temperature control accuracy. Utility Model Content

This device allows for flexible adjustment of the temperature sensor's position, enabling real-time temperature detection at multiple different locations within the pickling tank.

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] A temperature detection device for a steel strip pickling tank includes multiple temperature detection mechanisms evenly arranged along the length of the pickling tank 1.

[0023] The temperature detection mechanism includes multiple rotating shafts 2 that are rotatably mounted on the side wall of the pickling tank 1, and the multiple rotating shafts 2 are evenly distributed along the length of the pickling tank 1. The rotating shafts 2 are fixedly connected to swing rods 4 that are parallel to the side wall of the pickling tank 1, and the multiple swing rods 4 are rotatably connected to at least one connecting plate 5. The connecting plate 5 is fixedly connected to multiple temperature sensors 7. During the synchronous swinging of the multiple swing rods 4, the connecting plate 5 and the temperature sensors 7 can be moved within the pickling tank 1.

[0024] During the pickling process of steel strip, the temperature detection device of this invention is used to monitor the temperature of the acid solution in real time. During the detection process, one of the rotating shafts 2 can be driven to rotate, which in turn drives the connected swing rod 4 to swing within the pickling tank 1. In one temperature detection mechanism, when one swing rod 4 swings, it can drive the other swing rods 4 to swing synchronously via a connecting plate 5. This causes the connecting plate 5 to move up and down and left and right within the pickling tank 1. During the movement of the connecting plate 5, the temperature sensor 7 moves synchronously, thereby changing the position of the temperature sensor 7. This allows the temperature sensor 7 to detect different locations within the pickling tank 1. Each temperature detection mechanism can detect the real-time temperature at multiple different locations within the pickling tank 1. The coordinated operation of all temperature detection mechanisms can fully detect the temperature distribution within the pickling tank 1, facilitating precise temperature control and ensuring pickling efficiency.

[0025] This invention allows for flexible adjustment of the position of the temperature sensor 7, enabling real-time detection of the temperature at multiple different locations within the pickling tank 1. This results in a wider detection range and facilitates more precise temperature control within the pickling tank 1.

[0026] Furthermore, in the temperature detection mechanism, multiple swing rods 4 are rotatably connected to two connecting plates 5, with a gap 6 between the two connecting plates 5. The temperature sensor 7 is disposed in the gap 6. The two connecting plates 5 can adequately protect the temperature sensor 7, preventing damage from collisions or friction with the inner wall of the pickling tank 1. On the other hand, the cable of the temperature sensor 7 can also pass through a groove opened inside the connecting plate 5, thereby protecting the cable and preventing corrosion damage. Alternatively, a conduit can be additionally installed on the surface of the connecting plate 5, and the cable can pass through the conduit for cable protection.

[0027] To improve the structural strength and stability of the temperature detection mechanism, multiple reinforcing blocks 8 are fixedly connected between the two connecting plates 5. The reinforcing blocks 8 can support the two connecting plates 5, ensuring the stability of the gap 6 and thus protecting the temperature sensor 7. On the other hand, they can also connect the two connecting plates 5, facilitating the connection between the connecting plates 5 and the swing rod 4.

[0028] The specific connection method between the swing rod 4 and the connecting plate 5 is as follows: the swing rod 4 is fixedly connected to two oppositely oriented insertion rods 16, and the connecting plate 5 has insertion holes corresponding to the insertion rods 16. During installation, the two connecting plates 5 are respectively attached to both sides of the swing rod 4, and the two insertion rods 16 are inserted into the corresponding insertion holes. Then, the two connecting plates 5 are connected together using the reinforcing block 8. The connection method between the reinforcing block 8 and the connecting plate 5 can be welding. Accordingly, the connecting plate 5 and the reinforcing block 8 are made of metal and have undergone anti-corrosion treatment on the surface. The specific treatment process is a mature existing technology and will not be described in detail here.

[0029] To facilitate the rotation of one of the rotating shafts 2, the temperature detection mechanism includes two rotating shafts 2 at both ends, each fitted with a linkage pulley 10. These linkage pulleys 10 are located outside the pickling tank 1, and are connected by a first transmission belt 11. The temperature detection mechanism also includes a drive motor 14, which drives one of the rotating shafts 2 equipped with the linkage pulley 10. The drive motor 14 is located outside the pickling tank 1. When it is necessary to rotate the rotating shaft 2 to change the position of the temperature sensor 7, the drive motor 14 drives the connecting shaft 2. During rotation, this rotating shaft 2, through the cooperation of the linkage pulley 10 and the first transmission belt 11, drives the other rotating shaft 2 to rotate synchronously. The two rotating shafts 2 cooperate to better drive the swing rod 4 to swing within the pickling tank 1, thereby changing the position of the temperature sensor 7.

[0030] Furthermore, a drive pulley 15 is fixedly sleeved on the output shaft of the drive motor 14, and a driven pulley 12 is fixedly sleeved on a rotating shaft 2 driven by the drive motor 14. The drive pulley 15 and the driven pulley 12 are connected by a second transmission belt 13. During the operation of the drive motor 14, the drive pulley 15 is driven to rotate, which in turn drives the driven pulley 12 to rotate synchronously by the second transmission belt 13. The rotation of the driven pulley 12 can drive the connecting shaft 2 to rotate, and finally drive the other rotating shaft 2 to rotate synchronously through the first transmission belt 11. The temperature sensor 7 is moved up and down and left and right in the pickling tank 1 through the swing rod 4 and the connecting plate 5.

[0031] To prevent the drive motor 14, the first transmission belt 11, and the second transmission belt 13 from being damaged by the acid in the pickling tank 1, the temperature detection mechanism includes a protective shell 9. The protective shell 9 is fixedly installed on the side wall of the pickling tank 1 and located outside the pickling tank 1. The drive motor 14, the first transmission belt 11, and the second transmission belt 13 are all installed inside the protective shell 9.

[0032] The specific connection method between the rotating shaft 2 and the swing rod 4 is as follows: a connecting block 3 is fixedly connected to the middle of the rotating shaft 2, and the swing rod 4 is fixedly connected to the connecting block 3. A contraction section is provided in the middle of the rotating shaft 2, and a through hole is opened on the connecting block 3, with the contraction section located in the through hole. The cooperation between the contraction section and the through hole improves the stability of the swing rod 4 and prevents it from falling off the rotating shaft 2. During installation, the connecting block 3 can be fixed to the rotating shaft 2 using a bearing heat-fitting method, which is a mature existing technology and will not be elaborated further here.

[0033] In order to expand the detection range of the temperature detection mechanism, the rotating shaft 2 is close to the top of the pickling tank 1, and the swing rod 4 can drive the temperature sensor 7 to approach the bottom of the pickling tank 1 during the swing process.

[0034] Finally, it should be noted that both the connecting plate 5 and the temperature sensor 7 should be close to one side wall of the pickling tank 1 to avoid obstruction by the strip steel.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
