Description

Technical Field

[0001] The invention relates to the technical field of furnaces, in particular to a vertical thermal oil boiler furnace installation structure. Background Art

[0002] A thermal oil boiler is a boiler that uses thermal oil for heating. It typically uses coal, oil, or gas as fuel, and thermal oil as the medium. A thermal oil circulation pump forces the medium into liquid phase circulation, transferring heat energy to heat-consuming equipment before returning it to the heating furnace for reheating. It achieves high operating temperatures at low pressures and can perform high-precision control of the medium's operation.

[0003] For vertical furnaces, due to their high height, and considering the transportation height and installation convenience, they can only be assembled into furnaces by stacking sections. Figure 1 As shown, when installing the coil, the method is currently mainly to hoist it from the top of the bracket, so that the coils are stacked layer by layer. When installing in this way, the hoisting position of the coil cannot be accurately determined, and the structural stability after assembly cannot be guaranteed. Summary of the Invention

[0004] In order to solve the problems of inaccurate positioning and poor stability of the fixed structure during the installation of existing coils, the present invention provides a vertical thermal oil boiler furnace installation structure, which can achieve accurate installation of the coils and has a stable and reliable structure.

[0005] The technical solution is as follows: a vertical thermal oil boiler furnace installation structure, which includes a bracket and a coil, and the coils are stacked and welded from bottom to top to form a furnace, characterized in that a guide plate is welded on one side of each group of coils, and a guide groove matching the guide plate is installed on the bracket, and triangular positioning plates are welded at the four corners of the lowest layer of tubes in each group of coils, and multiple layers of right-angled V-shaped plates consistent with the number of coil groups are welded at the four corners of the bracket, and the right-angled notches of the right-angled V-shaped plates become smaller layer by layer from top to bottom, and the triangular positioning plates on the coils become smaller layer by layer from top to bottom, and the triangular positioning plates of each group of coils are supported on the right-angled V-shaped plates of the corresponding layer and welded fixed.

[0006] Its further feature is that a clearance groove is provided at the welding point between the guide plate and the coil.

[0007] After adopting the present invention, a guide plate is added to the coil. When the coil is hoisted, the guide plate is lowered along the guide groove, and the coil will not shake in the horizontal direction. The triangular positioning plate of each group of coils is supported on the right-angle V-shaped plate of the corresponding layer and welded and fixed, so that the coil is accurately positioned in the vertical direction, and the four corners are welded, which effectively ensures the reliable fixation of the coil and ultimately achieves the stability of the furnace rotation.

[0012] See Figures 2 to 4 As shown, a vertical thermal oil boiler furnace installation structure includes a bracket 1 and coils 2. The coils 2 are stacked and welded from bottom to top to form a furnace. Each group of coils 2 is provided with an oil inlet and an oil outlet. The oil inlet of each group of coils 2 is connected to the corresponding heating surface, and the oil outlet of each group of coils 2 is connected to an independent connecting pipe, which is connected to the ceiling pipe inlet header. A guide plate 4 is welded on one side of each group of coils 2, and a guide groove 5 that matches the guide plate 4 is installed on the bracket 1. Triangular positioning plates 6 are welded at the four corners of the lowest layer of pipes in each group of coils 2, and multi-layer right-angle V-shaped plates 7 that are the same as the number of groups of coils 2 are welded at the four corners of the bracket 1. The right-angled notch of the plate 7 becomes smaller layer by layer from top to bottom, and the triangular positioning plate 6 on the coil 2 becomes smaller layer by layer from top to bottom. During installation, the coil 2 of the lowest layer can pass through the upper right-angled V-shaped plate 7 smoothly but cannot pass through the right-angled V-shaped plate 7 of the lowest layer. The triangular positioning plate 6 is in contact with and supported at the upper end of the right-angled V-shaped plate 7 and welded fixed. Then, another layer of coil 2 is placed, which can also pass through the upper right-angled V-shaped plate 7 but cannot pass through the right-angled V-shaped plate 7 of the second layer. The triangular positioning plate 6 is in contact with and supported at the upper end of the right-angled V-shaped plate 7 of this layer, welded fixed and repeat the above operation. The triangular positioning plate 6 of each group of coils 2 is supported on the right-angled V-shaped plate 7 of the corresponding layer and welded fixed.

[0013] In order to facilitate the welding of the guide plate 4 , a clearance groove 3 is provided at the welding point between the guide plate 4 and the coil 2 .
