Abstract
Description
Technical Field
[0001] This utility model relates to the field of galvanized pipe drying technology, and in particular to a galvanized pipe drying device. Background Technology
[0002] Galvanized pipe is a type of steel pipe whose surface has been galvanized. The main purpose is to enhance the corrosion resistance and service life of the steel pipe by coating it with a layer of zinc. Galvanizing effectively prevents the steel pipe from rusting in humid, acidic, or alkaline environments, extending its service life in various fields such as construction, chemical, power, and transportation. If moisture remains on the surface of the galvanized pipe, the electrolytes in the moisture will form an electrochemical corrosion environment with the zinc coating and the steel pipe substrate. Although zinc is more reactive than iron and will generally corrode first to protect the steel pipe, in humid environments, the rate of electrochemical corrosion accelerates, damaging not only the zinc coating but also causing the steel pipe substrate to rust.
[0003] After the equipment is started, the pipes are fed into the drying chamber by an automated feeding device. They are heated by hot air circulation or infrared radiation. After drying, the pipes are cooled and then discharged. During operation, the internal zinc slag needs to be cleaned regularly, the heating elements need to be checked, and the sensors need to be calibrated.
[0004] In existing technologies, some galvanized pipe drying equipment requires adjustment of different galvanized pipe diameters and lengths during use. Small-diameter pipes may sway during transport, while large-diameter pipes may get stuck due to insufficient space, making it impossible to adapt to the production needs of different pipe specifications. Therefore, a galvanized pipe drying equipment is proposed to solve the above problems. Utility Model Content

The bottoms of the two guide bars 36 slide outside the conveyor belt 2.
[0036] Reference Figures 1 to 3 A pressing mechanism 4 is fixedly connected inside the protective cover 1. The pressing mechanism 4 is used to flip the galvanized pipe by pressing it. The pressing mechanism 4 includes a second cylinder 41, which serves as the driving source for the pressing mechanism 4. The second cylinder 41 is fixedly connected to the top of the protective cover 1. A square plate 42 is fixedly connected to the driving end of the second cylinder 41.

One end of the two springs 49 is fixedly connected to the bottom of the square plate 42, and the other end of the two springs 49 is fixedly connected to the top of the pushing block 45. Multiple heating tubes 6 are installed on both the left and right sides of the inner wall of the protective cover 1. Heating tubes 6 are used to heat the galvanized pipe.
[0038] Working principle: The worker places the galvanized pipe into the front end of the conveyor belt 2, and then the worker starts the cylinder 332, causing the drive end of the cylinder 332 to retract. The drive of the cylinder 332 causes the sliding block 333 to drive the connecting plate 35 to slide outside the sliding rail 34. As the sliding block 333 moves, it causes the two follower bars 37 to retract inward. As the follower bars 37 retract inward, they can drive the slider 38 to slide on the slide rail 322 fixed outside the connecting plate 321, and at the same time drive the two connecting bars 39 to retract inward. The movement of the connecting bars 39 will drive the guide bars 36 to retract inward. At this time, the two guide bars 36 can guide the placed galvanized pipe.
[0039] When the galvanized pipe is conveyed to the middle of the instrument, cylinder 41 can be activated. Cylinder 41 presses downwards, pushing square plate 42 and simultaneously pushing base plate 43 downwards. As square plate 42 presses down, spring 49 compresses and rebounds between push block 45 and square plate 42, causing push block 45 to push pressing plate 48 downwards. As the galvanized pipe passes below, pressing plate 48 presses against it, causing the pipe surface to rotate due to friction, thus ensuring even heating. When the copper-zinc pipes are of different sizes, pressing plate 48 can be pushed upwards. Spring 49 ensures that pressing plate 48 always maintains friction with the surface of the copper-zinc pipe, making it suitable for different sizes of copper-zinc pipes.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
