[0021] In the above technical solution, the flat-bottomed vertical cylindrical storage tank is a storage equipment widely used in industry for storing various gases, liquids and solid materials. Some materials require heating structures for heating due to their low crystallinity. In order to lay the heating structure close to the bottom surface 100 of the tank and improve the heating effect, the installation process of the heating structure of the bottom surface 100 of the tank is as follows: first, a clamp 2 is provided on the tank wall 110 close to the bottom surface 100 of the tank, so that the side with the wire clamping member 201 and the wire clamping part 202 is vertically facing downward, and when laying the heating cable 3, secondly, start laying the heating cable 3 on the bottom surface 100 of the tank, and fix one end of the heating cable 3 to the left side of the bottom surface 100 of the tank.

The other end is laid in a continuous S shape close to the bottom surface 100 of the tank to the right side of the bottom surface 100 of the tank. Every time it passes a wire clamping component 200, the bending part of the heating cable 3 is clamped into the wire clamping part 201 until it covers the entire bottom surface 100 of the tank. The fixing method of the heating cable 3 at the right end is the same as that of the left end.

After laying the heating cable 3, an insulation tape 4 is laid on the portion of the heating cable 3 that is not in contact with the tank bottom surface 100. The direction of the insulation tape 4 is consistent with that of the heating cable 3. Every time a wire clamping component 200 is passed, the bending part of the insulation tape 4 is clamped into the wire clamping part 202, wherein the two ends of the insulation tape 4 can be simultaneously pasted with the two ends of the heating cable 3 or fixed to the tank bottom surface by cable buckles.

The clamping component 5 can be a steel structure, which is fixedly connected to the tank bottom surface 100 by welding. The structural schematic diagram after the paving of the tank bottom surface 100 is as shown in the figure. Figure 1 As shown, the clamping part 1 201 and the clamping part 2 202 are made of heat-insulating materials, such as glass wool or foam glass with a combustion performance of Class A. For the bottom structure of a flat-bottomed vertical cylindrical storage tank, the heating cable 13 and the insulation belt 14 are laid in a continuous S shape close to the bottom surface 100 of the storage tank. The clamping part 1 201 and the clamping part 2 202 are used to clamp the bending parts of the heating cable 13 and the insulation belt 14, respectively, so as to avoid the problem of not being able to be close to the bottom 100 of the storage tank, and prevent the heating cable 13 from being in an over-tightened state, thereby improving the heating effect and avoiding tensile damage to the heating cable 13.

[0023] In the above technical solution, the flat-bottomed vertical cylindrical storage tank is a large-scale industrial equipment. In order to ensure a better heating effect, a heating structure needs to be laid on the tank wall 110. The laying process of the heating structure on the tank wall 110 is as follows: starting from the bottom of the tank wall, first fix one end of the heating cable 28 to a fixed wire hole 210 on the clamp 2, squeeze and press it through the elastic action of the elastic extrusion piece 211, and lay the other end vertically upward. When it reaches the top of the tank wall 110, wrap the heating cable 28 around the arc-shaped threading hole 711. At this time, the moving end of the heating cable 28 is vertically downward, and the heating cable 28 is laid vertically downward until it reaches the clamp 2 at the bottom 100 of the tank. When the heating cable 28 is wound around the arc portion 251, the moving end of the heating cable 28 is vertically upward, and the above operation is repeated until the entire tank wall 110 is laid, and the other end of the heating cable 28 is passed through another fixed wire hole on the clamp 12, and the two ends of the heating cable 28 are connected to the power supply device, wherein the power supply device here can be the same power supply device as the power supply device connected to the heating cable 13, or it can be a different power supply device, so as to realize the power supply heating of the heating cable 13 and the heating cable 28. The structural schematic diagram after the tank wall 110 is laid is as follows Figure 2 shown.

[0024] In another technical solution, the method for laying the insulated heating cable with a heat tracing structure further includes: Step 8: A plurality of hooks 220 are provided on the periphery of the hoop 2 and near the bottom of the hoop 2. The hooks 220 are in an inverted J-shaped structure. A plurality of hooks 700 are provided on the periphery of the hoop 7 and near the top of the hoop 7. The hooks 220 are in a J-shaped structure. Step nine, laying out an insulation belt 6 around the periphery of the tank wall 110, wherein the insulation belt 6 is provided with a plurality of hanging rings 600 near the bottom of the tank wall 110, and a plurality of hanging rings 610 near the top of the tank wall 110. The insulation belt 6 covers a plurality of heating cables 8 and is laid out around the periphery of the tank wall 110. During the laying process, each time a hook 220 is passed, a hanging ring 600 at a corresponding position is hung on the hook 220, and each time a hook 700 is passed, a hanging ring 610 at a corresponding position is hung on the hook 700.

[0025] In the above technical solution, if Figure 2 , 5, 6, 7 In order to prevent the heat of the heating cable 28 from being dissipated to the surrounding environment and ensure the heating effect of the heating cable 28, an insulation belt 26 is covered on the periphery of the heating cable 28, and the insulation belt 26 is wrapped around the tank wall 110, wherein the two ends of the insulation belt 26 can overlap, so as to achieve a good insulation effect, and the two ends of the insulation belt 26 can be pasted and fixed by heat release Velcro. The upper and lower ends of the insulation belt 26 are hung on the hook 2710 provided on the clamp 27 and the hook 220 provided on the clamp 12 respectively through the hanging ring 2700 and the hanging ring 1600, so as to prevent the insulation belt 26 from falling downward due to gravity and causing the insulation belt 26 to fail to completely cover the heating cable 28.

[0026] In another technical solution, in step four, the clamping member 5 includes: a supporting portion 510, a plurality of clamping portions 500 arranged on the supporting portion 510, and a connecting portion 520 connecting the supporting portion 510 and the plurality of clamping portions 500, each clamping portion 500 is pressed on the edge of the insulation belt 4 at a corresponding position, and the supporting portion 510 is supported on the ground or the installation foundation where the storage tank 1 is set.

[0027] In the above technical solution, if Figure 2As shown, a plurality of pressing parts 500 are arranged at intervals along the direction of the heating cable 3, and the two ends of each pressing part 500 press the edge of the insulation belt 4 at the corresponding position, and the middle is fixed to the bottom surface 100 of the storage tank, and each pressing part 500 is connected to the support part 510 through a connecting part 520, wherein the entire pressing member 5 can be a steel structure, and each pressing part 500 is welded to the bottom surface 100 of the storage tank. The use of the pressing member 5 can not only press the insulation belt 4, so that it is always kept in close contact with the heating cable 3, but also the pressing member 5 can separate the storage tank support from the ground or the installation foundation through the support part 510, so as to facilitate the observation and inspection of the bottom of the storage tank, and can easily find the leakage of the bottom of the storage tank.

[0028] In another technical solution, in step three, the material of insulation belt 1 4 and insulation belt 2 6 is the same, both comprising: a nanoporous insulation material layer and a glass wool layer, wherein the thickness of the nanoporous insulation material layer is 4 mm, the thickness of the glass wool layer is 3 mm, and there is a 1 mm air gap layer between the nanoporous insulation material layer and the glass wool layer.

[0029] In the above technical scheme, the nanoporous insulation material layer faces the heating cable surface and serves as the inner insulation layer. The nanoporous insulation material has the advantages of low thermal conductivity, high hydrophobicity and long service life. The degree of freedom of collision of gas molecules in the nanoporous insulation material is greater than the size of the pores, and heat transfer cannot occur. Due to the dense structure, it is extremely difficult for air to flow in the pores. Due to the small cross-sectional area and contact area of ​​the particles, the thermal conductivity is small. The nanoporous insulation material layer is made of Yuna nanoporous insulation material. A glass wool layer is provided outside the nanoporous insulation material layer as the outer layer of the insulation belt 1 4 or the insulation belt 2 6, and a certain air gap is provided between the nanoporous insulation material layer and the glass wool layer to reduce heat energy loss. By adopting the nanoporous insulation material, the thickness of the insulation belt is greatly reduced, reducing the construction cost. The material is safe and stable at high temperatures and has a high fire resistance level, avoiding blackening, smoking and even the production of toxic gases at high temperatures.

[0030] In another technical solution, the clamp 1 2 and the clamp 2 7 both include: Two semicircular clamp assemblies, the ends of the two semicircular clamp assemblies are connected together by a pair of buckling components 230; Four fixing screw holes are evenly distributed on two semicircular clamp assemblies; The fixing mechanism 240 includes four fixing screws 241 and four fixing washers 242. Each fixing screw 241 passes through each fixing screw hole and is threadedly connected to each fixing screw hole. Each fixing washers 242 is fixedly connected to the inner end of each fixing screw 241. The plurality of fixing washers 242 abut against the tank wall 110, thereby fixing the clamp 1 2 and the clamp 2 7 to the bottom and top of the tank wall 110 respectively. Among them, the diameter of the tank at the location where the clamps 1 2 and 2 7 are set is smaller than the diameter of the tank at the location where the heating cable 2 8 is laid, so that when the fixing screw 242 presses against the outer wall of the tank at the location where the clamps 1 2 and 2 7 are set, the heating cable 2 8 laid from the wire fixing hole 210 is close to the outer wall of the tank where the heating cable 2 8 is laid.

[0031] In the above technical solution, if Figure 5 As shown, when fixing the clamp 1 2 or the clamp 2 7, the two semicircular clamp assemblies, the ends of the two semicircular clamp assemblies are connected to the outer wall of the tank through a pair of buckling members 230, and the fixing screws 241 are gradually rotated inward, so that the fixing gaskets 242 gradually press against the specified position of the outer wall of the tank. Under the friction between the four fixing gaskets 242 and the outer wall of the tank, the clamp 1 2 or the clamp 2 7 is firmly fixed to the outer wall of the tank. In order to make the heating cable 2 8 laid on the tank wall 110 close to the tank wall 110, the distance between the clamp 1 2 or the clamp 2 7 and the tank wall 110 can be adjusted by adjusting the length of the fixing screws 241 extending to the specified position of the outer wall of the tank to achieve the best laying effect.

[0032] In another technical solution, the fastening component 230 includes a fastening nut 231 and a fastening screw 232. The fastening nuts 231 are respectively arranged at two adjacent ends of the two semicircular clamp assemblies. The fastening screw 232 is threadedly connected to the fastening nut 231 to connect the two adjacent ends of the two semicircular clamp assemblies together.

[0033] In the above technical solution, each semicircular clamp assembly has two ends, each end is provided with a fixing screw hole, the ends of the two semicircular clamp assemblies correspond one to one to form two connecting parts, and the two corresponding holes on each connecting part are connected through a fastening component 230, and each semicircular clamp assembly is connected into a whole through a pair of fastening components 230.
