Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial coating equipment technology, and in particular to a spraying equipment for antistatic and anticorrosive coating on the inner wall of a storage tank. Background Technology
[0002] In industrial production, storage tanks are widely used in chemical, petroleum, natural gas, and food processing industries, primarily for storing liquids, gases, or powders. Because storage tanks are exposed to corrosive media or high-temperature, high-humidity conditions for extended periods, their inner walls are highly susceptible to corrosion and oxidation, which can negatively impact equipment lifespan and safety. Furthermore, when storing flammable and explosive substances, if the tank's inner wall lacks adequate anti-static properties, static electricity buildup can lead to fires or explosions. Therefore, applying anti-static and anti-corrosion coatings to the inner walls of storage tanks has become a crucial measure to ensure their safe operation.
[0003] However, in practical applications, the spraying of the inner walls of storage tanks still faces numerous problems. On the one hand, traditional manual spraying methods are inefficient, labor-intensive, and the spraying quality is greatly affected by the operator's skill level, making it difficult to guarantee the uniformity and consistency of the coating. On the other hand, most existing spraying equipment has a fixed structure and poor adaptability to different specifications of storage tanks, resulting in insufficient equipment versatility. Simultaneously, during the spraying process, problems such as poor spray head stability, inaccurate guidance, and discontinuous paint supply are also prominent, easily leading to uneven coating thickness, missed areas, or repeated spraying. Furthermore, existing equipment lacks automatic adjustment functions in its support structure design, failing to effectively conform to the inner walls of storage tanks of different diameters, affecting the spraying effect and work efficiency. These problems severely restrict the development and application of automated spraying technology for the inner walls of storage tanks, necessitating a new type of spraying equipment with a reasonable structure, strong adaptability, stable operation, and the ability to achieve omnidirectional spraying.
[0004] Therefore, it is necessary to design an antistatic and anti-corrosion coating spraying equipment for the inner wall of storage tanks to solve the above-mentioned technical problems. Utility Model Content
[0005] In order to overcome the shortcomings of existing spraying equipment, which mostly have fixed structures and poor adaptability to different specifications of storage tanks, resulting in insufficient equipment versatility, this utility model provides a spraying equipment for antistatic and anticorrosion coating on the inner wall of storage tanks.
[0006] The technical solution is as follows: A tank inner wall antistatic and anti-corrosion coating spraying equipment includes a base, a tank frame, an electric slide rod, a guide rod, a spray head, a telescopic tube, and an adjustment component. The tank frame is fixedly connected to the rear top of the base. An electric slide rod is installed in the middle of the right side of the tank frame. A spray head is slidably connected to the electric slide rod. The upper and lower surfaces of the spray head are provided with nozzles. Guide rods are fixedly connected to the right side of the tank frame at positions on both sides of the electric slide rod. The left and right sides of the spray head are slidably connected to the guide rods respectively. A telescopic tube is connected and communicated to the lower part of the spray head. The telescopic tube extends to the rear side of the tank frame and is connected to the injection port of an external feeding device. An adjustment component is provided on the right side of the tank frame at a position outside the electric slide rod.
[0007] Optionally, the adjustment assembly includes an adjustment frame, a fixed frame, and fixed pulleys. Five adjustment frames are fixedly connected to the right side of the tank rack. Each adjustment frame has multiple mounting holes. The adjustment frames arranged horizontally and vertically form a cross-shaped structure. Each of the four adjustment frames is fixedly connected to a fixed frame through the mounting holes on its right side. Multiple fixed pulleys are rotatably connected to the side of each fixed frame that is close to each other.
[0008] Optionally, it also includes support rods and casters. Multiple support rods are rotatably connected to the outer periphery of the right end of the electric slide rod, and casters are rotatably connected to the outer end of each support rod.

Detailed Implementation
[0021] Example: An antistatic and anti-corrosion coating spraying device for the inner wall of a storage tank, such as... Figures 1-5 As shown, the device includes a base 1, a can rack 2, an electric slide bar 4, a guide bar 5, a spray head 6, a telescopic tube 7, and an adjustment assembly. The can rack 2 is bolted to the top rear side of the base 1. An electric slide bar 4 is installed in the middle of the right side of the can rack 2. The spray head 6 is slidably connected to the electric slide bar 4. The upper and lower surfaces of the spray head 6 are provided with nozzles. The guide bar 5 is bolted to the right side of the can rack 2 at the positions on both sides of the electric slide bar 4. The left and right sides of the spray head 6 are slidably connected to the guide bar 5 respectively. The lower part of the spray head 6 is connected to and communicates with the telescopic tube 7. The telescopic tube 7 extends to the rear side of the can rack 2 and is connected to the injection port 16 of the external feeding device. An adjustment assembly is provided on the right side of the can rack 2 at the position outside the electric slide bar 4.
[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the adjustment assembly includes an adjustment frame 3, a fixed frame 12, and fixed pulleys 13. Five adjustment frames 3 are bolted to the right side of the can rack 2. Each adjustment frame 3 has multiple mounting holes. The adjustment frames 3 arranged horizontally and vertically form a cross-shaped structure. Each of the four adjustment frames 3 is fixedly connected to a fixed frame 12 through mounting holes on its right side. Multiple fixed pulleys 13 are rotatably connected to the side of each fixed frame 12 that is close to each other, which are used to support and guide the movement of the spray head 6.
[0023] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes support rods 10, inclined plates 9, torsion springs 11, moving wheels 8, motors 14, and rotating wheels 15. Multiple support rods 10 are rotatably connected to the outer periphery of the right end of the electric slide rod 4. Each support rod 10 is connected to an inclined plate 9 by bolts on the upper right side to adapt to storage tanks of different specifications and improve the applicability of the equipment. Torsion springs 11 are connected to the transition parts between the support rods 10 and the electric slide rod 4 on both sides to realize the automatic reset function, enhance the structural stability and support capacity. Moving wheels 8 are rotatably connected to the outer ends of the support rods 10 to provide auxiliary support and reduce frictional resistance during the spraying process. The right side of the adjustment frame 3 on the upper right side of the tank rack 2 is equipped with a motor 14 with the output shaft on the right side through the mounting hole. Multiple rotating wheels 15 are connected to the output shaft of the motor 14 by bolts to drive the spray head 6 to rotate and realize all-round spraying.
[0024] Operators can apply the corresponding technical solutions in this device to the spraying of antistatic and anti-corrosion coatings on the inner wall of storage tanks, depending on the specific circumstances. When this device is needed to assist in the spraying operation, firstly, the entire equipment is placed stably on a horizontal surface using the base 1. Then, the position of the fixing frame 12 is adjusted to accommodate different specifications of storage tanks. The five cross-shaped adjusting frames 3 can be flexibly adjusted in position using the mounting holes according to actual needs, further enhancing the adaptability of the equipment. The electric sliding rod 4, with the center of the storage tank aligned with the tank frame 2, is slid in. The inclined plate 9 can automatically adjust its angle according to changes in the diameter of the storage tank, improving the versatility of the equipment. When the storage tank contacts the inclined plate 9, the support rod 10 will drive the moving wheel 8 to rotate to the left, and under the action of the torsion spring 11, it will abut against the inner wall of the storage tank. The torsion spring 11 enables the automatic reset function of the support rod 10 structure, enhancing the stability and reliability of the overall structure and allowing the spray head 6 to smoothly enter the tank. Subsequently, the positions of the fixed frame 12 and the motor 14 are adjusted through the mounting holes on the adjusting frame 3, so that the fixed pulley 13 and the rotating wheel 15 both abut against the outer wall of the tank. The fixed pulley 13 is used to support and guide the movement trajectory of the spray head 6, improving the stability during the movement process, and thus driving the tank that abuts against it to achieve the rotation function. The support rod 10 and the moving wheel 8 can closely adhere to the inner wall of the tank during the spraying process, providing auxiliary support and reducing frictional resistance, thereby improving the smoothness of equipment operation.
[0025] Once the device is secured, spraying can begin. First, the electric slide bar 4 drives the spray head 6 to slide horizontally. Then, the motor 14 is started to drive it to rotate. The motor 14 drives the rotating wheel 15 to rotate through its output shaft. Through the cooperation of the motor 14 and the spray head 6, the inner wall of the storage tank is fully covered by spraying. At the same time, the guide rod 5 guides and limits the spray head 6 to ensure its smooth operation. The upper and lower surfaces of the spray head 6 are equipped with nozzles. With the help of the telescopic tube 7 connecting to the external feeding device's injection port 16, paint is continuously supplied to the spray head 6, thereby achieving longitudinal spraying of the inner wall of the storage tank.
[0026] In summary, this antistatic and anti-corrosion coating spraying equipment for the inner wall of storage tanks achieves stable guidance, uniform coating, automatic reset, and all-around spraying during the spraying process through the coordinated work of multiple components, including electric slide bar 4, guide rod 5, spray head 6, telescopic tube 7, support rod 10, moving wheel 8, inclined plate 9, torsion spring 11, adjusting frame 3, fixed frame 12, fixed pulley 13, motor 14, and rotating wheel 15. It has the advantages of reasonable structure, simple operation, and strong adaptability, and is suitable for efficient spraying operations on the inner walls of various storage tanks.
