[0026] Specific implementation structure

[0027] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0028] Please refer to Figure 1-7 An example of the utility model provides an installation structure for a cooling tube row 2 of a roller kiln 1, comprising a roller kiln 1 and a plurality of groups of cooling tube rows 2, wherein a guide groove 6 is arranged inside the roller kiln 1, and the cooling tube row 2 is correspondingly installed below the guide groove 6, and a mounting member 3 is welded on one side of the cooling tube row 2, and a guide wheel 4 is arranged on the mounting member 3, and the guide wheel 4 can slide in cooperation with the guide groove 6, so that the cooling tube row 2 is suspended on the kiln top and slides in the guide groove 6, thereby simplifying the installation and replacement process of the cooling tube row 2; a flange 5 is arranged at the inlet and outlet of the cooling tube row 2, and a sealing gasket is arranged between the flange 5 and the outer wall of the roller kiln 1, and a pressure rod 7 is arranged on the roller kiln 1, and the flange 5 on the cooling tube row 2 is pressed against the outer wall of the roller kiln 1 by the pressure rod 7 and the sealing gasket, so that the cooling tube row 2 and the roller kiln 1 form a seal.

[0029] The cooperation between the guide wheel 4 and the guide groove 6 allows the cooling tube row 2 to be easily pulled out on the guide groove 6, thereby simplifying the installation and replacement process of the cooling tube row 2; the cooling tube row 2 adopts a suspended structure, which improves the stability of the equipment, enables the cooling tube row 2 to be made wider, reduces the number of cooling tube rows 2, reduces the joints and increases the heat exchange area; the cooling tube row 2 adopts a structural seal of a clamping flange 5, which reduces the difficulty of installation and improves the sealing performance of the equipment.

[0030] Furthermore, the cooling tube row 2 includes a plurality of elliptical tubes 21 and fins 22. The fins 22 are arranged on both horizontal sides of the long axis direction of the elliptical tube 21, which narrows the gap between adjacent fin tubes 1 and reduces heat dissipation. The fins 22 are welded on one side of the short axis direction of the elliptical tube 21, and the other side of the short axis direction of the elliptical tube is provided with a heat insulation layer or thermal insulation layer to reduce heat loss. The back of the elliptical tube 21 belongs to the inefficient heat exchange area. If the fins 22 are welded, the heat exchange efficiency of the fins 22 is not high, but the weight of the cooling tube row 2 is increased. Therefore, compared with the design of the traditional cooling tube row 2, a heat insulation layer or thermal insulation layer is provided on the back of the elliptical tube 21 to reduce the weight of the cooling tube row 2. Both ends of the elliptical tube 21 are connected with pipelines, and multiple elliptical tubes 21 are arranged side by side and connected by the pipelines to form a cooling water circuit, wherein one end of the pipeline is provided with a water inlet 9 and a water outlet 8 connected thereto, the water inlet 9 and the water outlet 8 are arranged on the same side, and a cooling water circuit with water inlet and outlet on the same side is formed by the cooling tube row 2 and the pipeline, so that multiple cooling tube rows 2 can be connected in series to improve the speed and heat exchange efficiency of the fluid. The elliptical tube 21 is pressed from a round tube, which increases the heat exchange area without changing the weight. When the roller conveyor transports the sagger carrying the material from the high-temperature heating area to the cooling area, the sagger slowly moves forward in the cooling area while exchanging heat with the cooling tube row 2 above and below the sagger, thereby cooling the material.

[0031] Furthermore, the mounting parts 3 have two groups, and the two groups of mounting parts 3 are respectively arranged along the arrangement direction of the cooling tube row 2, which can ensure the stability and load-bearing capacity of the cooling tube row 2 in the arrangement direction, and the mounting parts 3 are angle steels, which have high strength and stability and can bear the weight and heat load of the cooling tube row 2. Two groups of guide wheels 4 are arranged on each group of mounting parts 3, and the guide wheels 4 are fixedly installed on the mounting parts 3 by bolts. The cooling tube row 2 can be pushed into the guide groove 6 in the kiln through the installed guide wheels 4, so that the cooling tube row 2 can be suspended on the kiln top, thereby cooling the material.

[0032] Further, the guide groove 6 is arranged at the top of the inner side of the roller kiln 1, arranged along the length direction of the cooling tube row 2, and the guide groove 6 is welded to the roller kiln 1. The guide groove 6 is an L-shaped groove, which is convenient for the guide wheel 4 to slide.

[0033] The guide wheel 4 is installed on the cooling tube row 2. For the cooling tube row 2 above the gate bowl, the cooling tube row 2 can be pushed into the kiln through the guide groove 6 welded in the kiln, so that the cooling tube row 2 is suspended on the kiln top, thereby cooling the material. For the cooling tube row 2 below the material, it can be directly rolled into the bottom of the kiln through the guide wheel 4. After the cooling tube row 2 is installed in place, the sealing flange 5 of the cooling tube row 2 contacts the flange 5 on the outside of the roller kiln 1, and the flange 5 on the cooling tube row 2 is tightly pressed against the outer wall of the roller kiln 1 through the pressure rod 7 and the sealing gasket to form a seal.

[0034] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
