Description

Technical Field

[0001] The utility model relates to the technical field of drying and preheating devices, in particular to a hot-dip galvanizing production drying and preheating device for power towers. Background Art

[0002] As a crucial support structure for power transmission lines, the quality and durability of power towers are directly linked to the safety and stability of the power grid. To improve the corrosion resistance and extend the service life of power towers, hot-dip galvanizing is widely used in the surface treatment of tower prefabricated components. This process involves immersing the prefabricated components in molten zinc at high temperatures, evenly coating the surface with zinc, effectively preventing corrosion. However, prior to hot-dip galvanizing, the surface of the prefabricated components often contains a certain amount of moisture and impurities. If these are not properly treated, they will directly affect the quality of the galvanizing process and may even cause defects such as blistering and detachment of the galvanized layer.

[0003] Traditionally, natural air drying or simple heating equipment are mostly used for preheating and drying prefabricated parts of power towers. These methods have problems such as low efficiency, uneven drying, and high energy consumption. Especially when processing large or complex-shaped prefabricated parts, uneven heating often leads to excessively high local temperatures of the prefabricated parts, which in turn causes deformation or thermal stress concentration, seriously affecting the subsequent processing and installation quality. In addition, manual pushing of prefabricated parts for drying and preheating is not only labor-intensive, but also poses a risk of scalding, reducing operational safety. Therefore, in response to the above technical problems, a hot-dip galvanizing production drying and preheating device for power towers is proposed. Utility Model Content

[0015] The utility model proposes a hot-dip galvanizing production drying and preheating device for power towers.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-6 The utility model proposes a hot-dip galvanizing production drying and preheating device for power towers, comprising a device body 1, a mounting cover 2 fixedly connected to the upper side of the device body 1, an inlet and outlet 3 being opened on both sides of the mounting cover 2, and support components being installed on both sides of the device body 1;

[0025] The inside of the device body 1 is fixedly connected to a baking plate 6, and the baking plate 6 is a hollow frame structure. The baking plate 6 can play a supporting role inside the device body 1. The inside of the device body 1 is fixedly connected to a fixing rod 7, and the outside of the fixing rod 7 is fixedly connected to a thermoelectric component 8. The thermoelectric component 8 includes but is not limited to an electric heating plate, an infrared heater and other devices. A fan 9 is fixedly connected to the bottom of the inner side of the device body 1, and the thermoelectric component 8 is located on the upper side of the fan 9. The fan 9 can divert the heat emitted by the thermoelectric component 8 to the installation cover 2. A lifting and pushing mechanism is installed on the upper side of the thermoelectric component 8, and the lifting and pushing mechanism is installed near the baking plate 6.

[0026] The support assembly includes a support plate 4 and a reinforcing rod 5. The support plate 4 is fixedly connected to both sides of the device body 1, and the upper surface of the support plate 4 is flush with the upper surface of the device body 1. The baking plate 6 is fixedly connected to the bottom of the support plate 4, and the baking plate 6 and the device body 1 are fixedly connected.

[0027] A fixing plate 10 is fixedly connected to the inside of the device body 1, and the fixing plate 10 is located between the fixing rod 7 and the lifting and pushing mechanism. A partition net 11 is provided on the outside of the fixing plate 10. Installing the partition net 11 can prevent garbage on the surface of the prefabricated part from falling and affecting the operation of the fan 9.

[0028] The lifting and pushing mechanism includes a rotating rod 13, a mounting plate 14 and a protruding rod 15. The rotating rod 13 is rotatably connected to the inside of the device body 1, the mounting plate 14 is fixedly connected to the outside of the rotating rod 13, and the protruding rod 15 is fixedly connected to the outside of the mounting plate 14.

[0029] The number of the protruding rods 15 is several groups and they are arranged in a ring shape, and the protruding rods 15 can protrude from the upper surface of the baking plate 6, which makes it easy to lift and push the preforms.

[0030] The outside of the device body 1 is fixedly connected to a driving motor 12 , and the driving motor 12 is fixedly connected to the rotating rod 13 . The driving motor 12 can drive the rotating rod 13 to rotate when it is running.

[0031] A vent 16 is provided on the upper side of the device body 1, which allows hot air to drive water molecules on the surface of the preform to be discharged from the mounting cover 2.

The controller 17 can control the operation of the thermoelectric component 8, the fan 9 and the drive motor 12.

[0032] The working principle of a hot-dip galvanizing production drying and preheating device for power towers according to the embodiment is as follows: when the surface of a prefabricated part of a power tower needs to be preheated and dried before the prefabricated part is dipped in the flux plating agent to avoid deformation of the prefabricated part due to excessive moisture and high temperature, the fan 9 can be operated first and the thermoelectric component 8 can be energized, so that a high-temperature environment with hot air blowing upwards can be created inside the device body 1. At this time, one end of the prefabricated part can be inserted into the inlet and outlet 3 on one side, and the prefabricated part can be placed on the support plate 4 on one side. At this time, the part of the prefabricated part inserted into the mounting cover 2 will be quickly dried and preheated. At this time, although the prefabricated part located outside the mounting cover 2 is not inserted into the interior for heating and drying, its exterior will generate a high temperature due to heat transfer, which is not convenient for manual pushing. At this time, the two sets of drive motors 12 can be operated synchronously to rotate the rotating rod 13, so that the internal rotating disk drives the protruding rod 15 to rotate toward the inlet and outlet 3 on the other side, so that the prefabricated part can be lifted and then output to the inlet and outlet 3 on the other side, which facilitates automatic horizontal pushing for drying and preheating without manual pushing, thereby greatly improving the operation safety index.
