[0002] Heating devices for tank exterior coatings are primarily used to heat the tank exterior in low-temperature environments to ensure uniform curing of the coating and improve its adhesion and durability. In industries such as petrochemicals, food processing, and pharmaceuticals, anti-corrosion coatings on tank exteriors are crucial for protecting equipment from corrosion.

[0003] Currently, common tank exterior coating heating devices use hot air blowers to blow hot air onto the tank exterior. However, this method is difficult to achieve uniform heating of the tank exterior, resulting in inconsistent coating curing effects and uneven heat distribution. There is an urgent need for a tank exterior coating heating device to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heating device for the outer wall coating of storage tanks to solve the problems mentioned in the background technology. This utility model designs a rotary heating structure that can uniformly heat the outer wall coating of the storage tank while lifting and fixing it in a limited position.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tank outer wall coating heating device, comprising a supporting base plate, a rotating frame, and a tank. A column is longitudinally fixed at the upper middle of the supporting base plate, and a fixed carrier plate is horizontally fixed at the upper end of the column. A stepped bearing is installed on the annular side of the column, and a spur gear is fixedly sleeved at the lower end of the outer ring of the stepped bearing. A rotating frame is horizontally fixed at the upper end of the outer ring of the stepped bearing, and a ball bearing is embedded in the upper end of the rotating frame. An electric push rod is installed through the ball bearing, and a limit plate is horizontally installed at the movable end of the electric push rod. The tank is placed longitudinally on the fixed carrier plate. Horizontal guide rods are horizontally installed on the upper and lower sides of the left end of the rotating frame via bolts and flanges. Multiple threaded holes are opened at the front ends of the two horizontal guide rods, and connecting blocks are slidably sleeved on the outside of the two horizontal guide rods. A heating tube shell is longitudinally fixed between the two connecting blocks, and a heating tube is longitudinally installed inside the heating tube shell.

[0006] Furthermore, a servo motor is longitudinally mounted on the upper right side of the support base plate, and a drive gear is mounted on the shaft end of the servo motor. The drive gear meshes with a spur gear for transmission. The servo motor, heating tube, and electric push rod are programmed and controlled by an external PLC controller.

[0007] Furthermore, the upper end of the storage tank abuts against the limiting plate.

[0008] Furthermore, each of the two connecting blocks is longitudinally mounted with a one-way wheel at its opposite outer end, and the two one-way wheels slide against the upper and lower ends of the rotating frame respectively.

[0009] Furthermore, multiple limiting bolts are screwed onto the front ends of both connecting blocks.

[0010] Furthermore, the threaded ends of the plurality of limiting bolts are respectively inserted into several of the plurality of threaded holes.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a tank outer wall coating heating device.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3This utility model provides a technical solution: a heating device for the outer wall coating of a storage tank, including a supporting base plate 1, a rotating frame 7, and a storage tank 17. A column 2 is longitudinally fixed at the middle of the upper end of the supporting base plate 1. A fixing plate 18 is horizontally fixed at the upper end of the column 2. A stepped bearing 3 is installed on the annular side of the column 2. A spur gear 4 is fixedly sleeved at the lower end of the outer ring of the stepped bearing 3. The rotating frame 7 is horizontally fixed at the upper end of the outer ring of the stepped bearing 3. A ball bearing 8 is embedded in the upper end of the rotating frame 7. An electric push rod 9 is installed through the ball bearing 8. A limit plate is horizontally installed at the movable end of the electric push rod 9. The storage tank 17 is placed longitudinally... Placed on the fixed carrier plate 18, the rotating frame 7 has horizontal guide rods 10 installed horizontally on the upper and lower sides of the left end through bolts and flanges. The front ends of the two horizontal guide rods 10 are provided with multiple threaded holes 11. The two horizontal guide rods 10 are slidably fitted with connecting blocks 12. A heating tube shell 14 is longitudinally fixed between the two connecting blocks 12. A heating tube 15 is longitudinally installed inside the heating tube shell 14. This design solves the problem that the original device blows hot air to the outer wall of the storage tank through a hot air blower. This method is difficult to achieve uniform heating of the outer wall of the storage tank, resulting in inconsistent coating curing effect and uneven heat distribution.

[0019] As the first embodiment of this utility model: a servo motor 5 is longitudinally mounted on the upper right side of the support base plate 1, and a drive gear 6 is mounted on the shaft end of the servo motor 5. The drive gear 6 meshes with the spur gear 4 for transmission. The servo motor 5, the heating tube 15, and the electric push rod 9 are controlled by an external PLC controller. The external PLC controller is an existing mature device, and its control principle should be known to those skilled in the art, so it will not be described in detail. The upper end of the storage tank 17 abuts against the limiting plate. By placing the added storage tank 17 longitudinally on the fixed carrier plate 18, the upper end of the storage tank 17 abuts against the limiting plate, which can limit and fix the storage tank 17 for the outer wall coating.

[0020] Two connecting blocks 12 are each longitudinally mounted with one-way wheels 16 at their opposite outer ends. The two one-way wheels 16 slide against the upper and lower ends of the rotating frame 7 respectively. By adding the two one-way wheels 16, which slide against the upper and lower ends of the rotating frame 7 respectively, the two connecting blocks 12 move more smoothly in the horizontal direction outside the two horizontal guide rods 10.

[0021] Multiple limiting bolts 13 are screwed onto the front ends of both connecting blocks 12. The threaded ends of the multiple limiting bolts 13 are inserted into several threaded holes 11. By inserting the threaded ends of the multiple limiting bolts 13 into several threaded holes 11, the two connecting blocks 12 can be fixed to the outside of the two horizontal guide rods 10, thereby achieving the limiting and fixing of the heating tube shell 14.

[0022] As a second embodiment of this utility model: the outer wall coating storage tank 17 is placed on the fixed carrier plate 18, and then the electric push rod 9 is activated, causing the movable end of the electric push rod 9 to move the limiting plate downward until the upper end of the storage tank 17 abuts against the limiting plate. Then, the heating tube shell 14 is pushed to the right, causing the two connecting blocks 12 to move to the right outside the two horizontal guide rods 10, and the two one-way wheels 16 to move to the right at their upper and lower ends inside the rotating frame 7, until the heating tube 15 is 1 cm away from the left side wall of the storage tank 17. Then, the multiple limiting bolts 13 are tightened, so that the threaded ends of the multiple limiting bolts 13 are respectively inserted into several of them. Within the multiple threaded holes 11, the servo motor 5 is activated, driving the drive gear 6 to rotate. The rotation of the drive gear 6 drives the spur gear 4 to mesh and rotate, thereby causing the outer ring of the stepped bearing 3 to rotate. This allows the rotating frame 7 to rotate (during this process, the outer ring of the ball bearing 8 rotates, while the inner ring of the ball bearing 8 and the electric push rod 9 remain stationary). The heating tube shell 14 on its inner side is also driven to rotate through the two horizontal guide rods 10, thus realizing the rotation of the heating tube 15 outside the storage tank 17. During this process, the outer wall of the storage tank 17 can be rotated and heated evenly.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0024] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
