[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Reference Figures 1-4This utility model provides a height-adjustable air-temperature vaporizer defrosting device, including a base plate 10 and a top plate 22. Several rotationally symmetrical first sliding plates 13 are welded to the upper surface of the base plate 10, and several rotationally symmetrical second sliding plates 15 are welded to the lower surface of the top plate 22. A sliding groove 14 is provided on one side of each second sliding plate 15 to slide and connect with the first sliding plates 13. An air outlet pipe 4 is rotatably connected inside the top plate 22, with both ends of the air outlet pipe 4 passing through the top plate 22. Several rotationally symmetrical guide pipes 19 are welded to the outer wall of the air outlet pipe 4 and located at the bottom of the top plate 22. 9 is connected to the exhaust pipe 4. A second jet pipe 17, connected to the other end of the guide pipe 19, is welded to it. A first jet pipe 16 is slidably connected to the inner wall of the second jet pipe 17. Several equidistant through holes 21 are provided on the outer walls of both the first jet pipe 16 and the second jet pipe 17. An anti-deviation assembly for guiding several first jet pipes 16 is provided on the upper surface of the base plate 10. A power assembly for driving the top plate 22 to move up and down is provided on the upper surface of the base plate 10. The power assembly includes a support frame 9 welded to the upper surface of the base plate 10. The lower surface of the top plate 22 is rotatably connected to a support frame 9 via an axis. The support frame 9 is threaded to a threaded rod 8. A servo motor that drives the threaded rod 8 to rotate along the axis is installed on the upper surface of the top plate 22. A heat transfer gas assembly is provided on the top of the top plate 22. The heat transfer gas assembly delivers hot gas to the outlet pipe 4. The hot gas is split into various guide pipes 19 through the outlet pipe 4, and then enters the second jet pipe 17 through the guide pipes 19. Subsequently, it is sprayed onto the vaporizer through the through holes 21 opened on the outer wall of the second jet pipe 17 and the first jet pipe 16. The servo motor is started, and the servo motor drives the threaded rod 8 to rotate. The rotation of the threaded rod 8 will cause the top plate 22 to move downward, moving the top plate 22 close to the vaporizer. At the top of the device, when the top plate 22 moves downward, the first sliding plate 13 slides in the groove 14 opened on one side of the second sliding plate 15, and at the same time, the first jet pipe 16 slides in the second jet pipe 17, thereby realizing flexible adjustment of the height of the defrosting device, so that it can be used for short vaporizers and avoid the phenomenon of heating gas blasting. It can also be used for vaporizers of different heights, as long as its size is not higher than the sum of the sizes of the first sliding plate 13 and the second sliding plate 15, and the through holes 21 are opened relatively closely, so that the second jet pipe 17 will not block the through holes on the surface of the first jet pipe 16.

[0025] In this application, the inner wall of the threaded hole of the support frame 9 that mates with the threaded rod 8 is provided with an annular groove. A nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the surface of the threaded rod at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3m, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing loosening displacement caused by thread springback.

[0026] In this embodiment, the anti-deviation assembly includes a slide rail 11 fixed to the upper surface of the base plate 10 by bolts. A connecting plate 12 is slidably connected to one side of the slide rail 11 via a slide table, and the connecting plate 12 is fixed to several first jet pipes 16. A rotary assembly for driving the exhaust pipe 4 to reciprocate is provided on the upper surface of the top plate 22. The rotary assembly includes a fixing frame 5 fixed to the upper surface of the top plate 22 by bolts. A first gear 6 is rotatably connected to the inner top wall of the fixing frame 5 via a bearing. A stepper motor for driving the first gear 6 to rotate along its axis is mounted on the top of the fixing frame 5. A second gear 7 meshing with the first gear 6 is connected to the outer wall of the exhaust pipe 4 via a key. The exhaust pipe 4 is located on the second gear 7. A rotary joint 18 is provided at the top. When the stepper motor is started, the stepper motor drives the first gear 6 to rotate forward. The rotation of the first gear 6 drives the second gear 7 to rotate forward. After rotating 120 degrees, the stepper motor drives the first gear 6 to rotate in reverse. The rotation of the first gear 6 drives the second gear 7 to rotate in reverse. After rotating 120 degrees, it rotates forward again. This process repeats, thereby driving the air outlet pipe 4 to rotate back and forth. The air outlet pipe 4 drives multiple first jet pipes 16 and multiple second jet pipes 17 to rotate back and forth through multiple guide pipes 19. At the same time, the multiple first jet pipes 16 drive the connecting plate 12 to slide along the direction of the slide rail 11, thereby achieving uniform defrosting of the vaporizer and greatly improving the defrosting efficiency of the vaporizer.

[0027] In this embodiment, the heat transfer gas assembly includes an air pump 1 fixed to the upper surface of the top plate 22 by bolts. The top end of the air outlet pipe 4 is welded to a housing 3 connected to it. The top end of the outer wall of the housing 3 is welded to a connecting pipe 2 connected to it. The other end of the connecting pipe 2 is connected to the air outlet of the air pump 1. The inner wall of the housing 3 is provided with a heating assembly for heating the gas. The heating assembly includes a heating wire 20 installed on the inner wall of the housing 3 to heat the gas. After the air pump 1 is started, external air is drawn into the housing 3 through the connecting pipe 2. The heating wire 20 is started to heat the gas entering the housing 3. The heated gas is then introduced into the air outlet pipe 4.

[0028] In this embodiment, the slide rail 11 is arc-shaped and concentric with the air outlet pipe 4.

[0029] In this embodiment, an annular roller blind is installed at the edge of the upper surface of the top plate 22. When the annular roller blind is unfolded, it can prevent excessive heat loss to the surrounding environment and improve the utilization rate of heat.

[0030] It should be noted that the servo motor, stepper motor and air pump are all existing technologies, and those skilled in the art can set them according to actual needs, which will not be elaborated here.

[0031] The use of this utility model involves the following steps:

[0032] S1: Move the defrosting device to the outside of the vaporizer, and then unfold the annular roller shutter;

[0033] S2: Then start the servo motor, the servo motor drives the threaded rod 8 to rotate, the rotation of the threaded rod 8 will drive the top plate 22 to move downward, move the top plate 22 to a position close to the top of the gasifier. When the top plate 22 moves downward, the first slide plate 13 slides in the groove 14 opened on one side of the second slide plate 15, and at the same time, the first jet pipe 16 slides in the second jet pipe 17.

[0034] S3: Next, start the air pump 1 to draw outside air into the housing 3 through the connecting pipe 2, start the heating wire 20 to heat the gas entering the housing 3, and then pass the heated gas into the outlet pipe 4. The hot gas is divided into each guide pipe 19 through the outlet pipe 4, and then enters the second jet pipe 17 through the guide pipe 19. Then it is sprayed out from the through hole 21 opened on the outer wall of the second jet pipe 17 and the first jet pipe 16, and sprayed onto the surface of the vaporizer to defrost it.

[0035] S4: Simultaneously start the stepper motor, which drives the first gear 6 to rotate forward. The rotation of the first gear 6 drives the second gear 7 to rotate forward. After rotating 120 degrees, the stepper motor drives the first gear 6 to rotate in reverse. The rotation of the first gear 6 drives the second gear 7 to rotate in reverse. After rotating 120 degrees, it rotates forward again. This process repeats, thereby driving the exhaust pipe 4 to rotate back and forth. The exhaust pipe 4 drives multiple first jet pipes 16 and multiple second jet pipes 17 to rotate back and forth through multiple guide pipes 19. At the same time, the multiple first jet pipes 16 drive the connecting plate 12 to slide along the direction of the slide rail 11, thereby evenly defrosting the vaporizer.

[0036] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
