Description

Technical Field

[0001] This utility model relates to the field of special paper slurry production line technology, specifically an improved automatic heating device for steel strip in slurry production line. Background Technology

[0002] Thick slurry production lines are core production lines in industries such as building materials and chemicals, used for processing refractory materials, insulation slurries, and other thick slurry-like materials. They primarily handle material conveying, leveling, and forming operations. The steel belt, as a key component for load-bearing and transmission, directly determines the material forming quality and production continuity based on its temperature stability. Traditional steel belt heating equipment often uses localized heat sources and manual control, resulting in uneven temperature distribution, high energy consumption, and delayed heating response. This can easily lead to material sticking to the steel belt, insufficient forming accuracy, and increased manual maintenance costs.

[0003] The existing method of heating steel strips in thick slurry production lines is steam heating, which results in high energy consumption and long-term steam combustion, which can easily cause environmental pollution and has low practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an improved automatic heating device for steel strip in thick slurry lines, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: an improved automatic heating device for steel strip in a thick slurry production line, including a lower drying oven and an upper drying oven, and a steel strip body located between the lower drying oven and the upper drying oven. A support foot is fixedly installed at the bottom end of the lower drying oven away from the upper drying oven. A groove is formed at the end of the lower drying oven near the upper drying oven. An infrared plate bracket is fixedly installed at the end of the lower drying oven near the upper drying oven. An infrared heating plate is provided on the side of the infrared plate bracket away from the lower drying oven. A fixing frame is fitted onto the outer surface of the infrared heating plate. A slot is formed at the end of the infrared plate bracket near the infrared heating plate. A locking block is fixedly installed at the end of the fixing frame near the infrared plate bracket. An installation groove is formed at the top of the lower drying oven near the outlet section of the steel strip body. A temperature sensor is provided inside the installation groove. A positioning groove is formed at the end of the temperature sensor near the installation groove. A spring block is fixedly installed at the end of the temperature sensor near the installation groove. Positioning blocks are fixedly installed at both ends of the inner wall of the installation groove. A snap-fit ​​groove is formed at the bottom of the positioning block.

[0006] Preferably, a fixed seat is fixedly installed on both sides of the inner wall of the groove, and a roller is rotatably installed on the inner side of the fixed seat. The roller is slidably connected to the steel strip body.

[0007] The above technical solution, by setting the idler roller and the steel belt body to be in a sliding connection, can convert sliding friction into rolling friction, which can reduce the resistance of the steel belt body during operation, reduce energy loss and extend the service life of the steel belt body. In addition, by setting the idler roller, the steel belt body is supported and prevented from falling onto the infrared heating plate.

[0008] Preferably, the lower oven and the upper oven are provided with eight identical sets, and each set of the lower oven and the upper oven is provided with six identical sets of infrared heating plates.

[0009] By using the above technical solution, with six sets of infrared heating plates in each oven, the steel strip body is divided into multiple heating sections, which can achieve precise segmented heating of the steel strip body and avoid local overheating or underheating.

[0010] Preferably, the cross-section of the card block is L-shaped, the card block is adapted to the card slot, and a locking screw is provided on the side of the fixing frame away from the infrared plate bracket. The locking screw passes through the fixing frame and extends into the interior of the infrared plate bracket.

[0011] The above technical solution, by setting the cross-section of the card block to be "L" shaped and the card block to be compatible with the card slot, facilitates the quick alignment and installation of the fixed frame and the infrared plate bracket. The locking screw passes through the fixed frame and extends into the interior of the infrared plate bracket, further strengthening the connection between the fixed frame and the infrared plate bracket. At the same time, the threaded connection also facilitates the quick disassembly of the fixed frame and the infrared plate bracket, greatly reducing maintenance difficulty and time costs.

[0012] Preferably, the infrared heating plate is made of graphene material, and the infrared plate support is formed by folding.

[0013] The above technical solution utilizes graphene material for the infrared heating plate, which has high electrothermal conversion efficiency and faster heating speed, significantly reducing energy consumption costs. Furthermore, the infrared plate support is formed by folding edges, which effectively improves rigidity, reducing material usage and overall equipment weight while ensuring support strength.

[0014] Preferably, the positioning groove is adapted to the cross-section of the positioning block, the positioning groove and the positioning block are plugged in, and the spring block can be snapped into the snap groove.

[0015] The above technical solution enables rapid positioning of the temperature sensor through the insertion and cooperation of the positioning slot and the positioning block. The snap-fit ​​connection between the spring block and the slot can be completed without tools, which greatly shortens the temperature sensor calibration and replacement time and improves work efficiency.

This improved automatic heating equipment for steel strip in thick slurry production line features an "L"-shaped cross-section for the locking block, which is compatible with the slot. This facilitates quick alignment and installation of the fixed frame and the infrared plate bracket. Furthermore, the locking screws penetrate the fixed frame and extend into the interior of the infrared plate bracket, further strengthening the connection between the fixed frame and the infrared plate bracket. At the same time, the threaded connection also facilitates quick disassembly of the fixed frame and the infrared plate bracket, significantly reducing maintenance difficulty and time costs. 2. This improved automatic heating equipment for steel strip in thick slurry production line uses infrared plate electric heating, which has adjustable temperature and low energy loss due to direct heating. At the same time, it does not generate air pollution due to the combustion of steam, thus achieving the purpose of energy saving and environmental protection. Attached Figure Description

[0021] Specifically, fixed seats 5 are fixedly installed on both sides of the inner wall of the groove 4, and rollers 6 are rotatably installed on the inner side of the fixed seats 5. The rollers 6 are slidably connected to the steel strip body 19. The advantage is that by setting the rollers 6 and the steel strip body 19 to be slidably connected, sliding friction can be converted into rolling friction, which can reduce the resistance of the steel strip body 19 during operation, reduce energy loss and extend the service life of the steel strip body 19. In addition, by setting the rollers 6, the steel strip body 19 is supported and prevented from falling onto the infrared heating plate 8.

[0022] Specifically, the lower oven 1 and the upper oven 2 are equipped with the same eight sets, and each set of the lower oven 1 and the upper oven 2 is equipped with the same six sets of infrared heating plates 8. The advantage is that by setting six sets of infrared heating plates 8 in each oven, the steel strip body 19 is divided into multiple heating sections, which can achieve segmented and precise heating of the steel strip body 19 and avoid local overheating or underheating.

[0023] Specifically, the locking block 11 has an "L"-shaped cross-section and is adapted to the locking slot 10. A locking screw 12 is provided on the side of the fixing frame 9 away from the infrared plate bracket 7. The locking screw 12 passes through the fixing frame 9 and extends into the interior of the infrared plate bracket 7.

At the same time, the threaded connection facilitates the quick disassembly of the fixing frame 9 and the infrared plate bracket 7, greatly reducing maintenance difficulty and time costs. Subsequently, the temperature sensor 14 is quickly positioned by the insertion and cooperation of the positioning slot 15 and the positioning block 17. The snap-fit ​​connection between the spring block 16 and the buckle slot 18 can be completed without tools, greatly shortening the calibration and replacement time of the temperature sensor 14 and improving work efficiency.
