Abstract
Description
Technical Field
[0001] This application relates to the technical field of surface treatment of ground source heat pump heat pipes, and in particular to a device for anti-corrosion treatment of the surface of ground source heat pump heat pipes. Background Technology
[0002] The heat pipe of a ground source heat pump is one of the key components of a ground source heat pump system. It mainly uses shallow underground geothermal resources (including soil, groundwater, etc.) for heat exchange. Its working principle is based on heat conduction and fluid phase change. Since it needs to be buried underground, the moisture in the soil will cause the formation of an electrolyte solution on the surface of the heat pipe, which will lead to electrochemical corrosion. Moreover, the soil acidity (pH value) varies greatly in different regions, which means that the outside of the pipe usually needs to be treated with anti-corrosion measures.
[0003] A search revealed Chinese patent application CN202220491191.6, which discloses a surface treatment device for anti-corrosion treatment of steel pipes. The device includes a base box, with a housing fixedly connected to the upper surface of the base box. A drive motor is mounted on the upper surface of the housing, and a lead screw is mounted on the output end of the drive motor. A movable plate is threaded onto the surface of the lead screw, and the lower surface of the movable plate extends to the inner wall of the housing and is fixedly connected to an inverted U-shaped movable frame. A spraying pipe is mounted on the surface of the movable frame, and several supporting guide rollers are rotatably connected to the inner wall of the housing. This surface treatment device for anti-corrosion treatment of steel pipes, by incorporating a drive motor, lead screw, movable frame, and inverted U-shaped spraying pipe, allows the movable frame to move left and right under the action of the drive motor, thereby driving the spraying pipe to spray anti-corrosion coating onto the surface of the steel pipe. During the spraying process, the supporting guide rollers facilitate the feeding and discharging of the steel pipe and allow for rotation of the steel pipe, improving the spraying effect of the anti-corrosion coating.
[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: During the spraying process, the ground source heat pump heat pipe may become contaminated with dust in the production workshop, during transportation, or at the construction site. In the production workshop, dust from the surrounding environment may fall onto the heat pipe; during transportation, the heat pipe may be exposed to dusty environments; and at the construction site, excavation and other construction activities generate a large amount of dust, which easily adheres to the heat pipe, forming sludge. This sludge also reduces the adhesion between the coating and the heat pipe, creating gaps between the coating and the heat pipe surface, affecting the adhesion between the two, and resulting in a reduction in the quality of subsequent protective spraying.

Detailed Implementation
[0023] The following is in conjunction with the appendix Figure 1 —5 provides further detailed description of this application.
[0024] This application discloses a device for surface anti-corrosion treatment of ground source heat pump heat pipes. For example... Figure 1 - Figure 5 As shown, the device includes a processing plate 1, two conveying frames 2 are fixedly connected to the upper side of the processing plate 1, a conveying mechanism 3 is provided on the lower side of the inner wall of the conveying frame 2, a pressing mechanism 4 is provided on the upper side of the inner wall of the conveying frame 2, a support plate 5 is fixedly connected to one side of the processing plate 1, a wire passage 6 is opened on one side of the support plate 5, a rotating ring 7 is rotatably fitted on one side of the support plate 5, and multiple scrapers 8 are provided on one side of the rotating ring 7.
[0025] Please see Figure 3 Multiple adjustment grooves 16 are provided on one side of the rotating ring 7. Adjustment screws 17 are rotatably fitted on the inner walls of the multiple adjustment grooves 16. Adjustment blocks 18 are threaded onto the multiple adjustment screws 17. The multiple adjustment blocks 18 are fixed to the multiple scrapers 8. By rotating the adjustment screws 17 in the adjustment grooves 16, the adjustment blocks 18 are moved a certain length inside the adjustment grooves 16, thereby causing the scrapers 8 to tighten to different degrees, so as to be applicable to pipes of different diameters and improve the applicability of pipe treatment.
[0026] Please see Figure 1 and Figure 5 The conveying mechanism 3 includes a support frame 301 fixedly connected to the lower inner wall of the two conveying frames 2, a conveying shaft 302 rotatably fitted to the inner wall of the two support frames 301, a linkage rod 303 fixedly connected to one side of the conveying shaft 302, an extension plate 304 fixedly connected to the processing plate 1, a stepper motor 305 fixedly connected to one side of the extension plate 304 and fixed to one end of one of the two linkage rods 303, a synchronous pulley 306 fixedly connected to the two linkage rods 303, and a synchronous belt 307 set on the two synchronous pulleys 306. The stepper motor 305 drives the synchronous pulley 306 to rotate, and the synchronous belt 307 causes the two linkage rods 303 and the conveying shaft 302 to rotate synchronously, so as to maintain a stable state during pipeline conveying.
[0027] Please see Figure 5 The pressing mechanism 4 includes an installation port 401 opened on the upper side of the inner wall of the conveying frame 2, an electric telescopic rod 402 fixedly connected to the inner wall of the installation port 401, a pressing frame 403 fixedly connected to the output end of the electric telescopic rod 402, and a pressing shaft 404 rotatably fitted on the inner wall of the pressing frame 403 and cooperating with the conveying shaft 302. By activating the electric telescopic rod 402 in the installation port 401, the pressing frame 403 and the pressing shaft 404 are pushed downward, so that they abut against the conveying shaft 302, which facilitates clamping and binding the intermediate pipe.
[0028] A drive motor 9 is fixedly connected to the upper side of the support plate 5. A drive gear 10 is fixedly connected to the output end of the drive motor 9. A driven gear 11 that meshes with the drive gear 10 is fixedly connected to the outer side of the rotating ring 7. A spraying assembly 12 and a drying assembly 13 are provided on the upper side of the processing plate 1 away from the support plate 5.
[0029] Please see Figure 1 The spraying assembly 12 includes a hollow frame 121 fixedly connected to the processing plate 1, a liquid pump 122 fixedly connected to both sides of the hollow frame 121, and two spray plates 123 fixedly connected to the output ends of the two liquid pumps 122 and located inside the hollow frame 121. The input end of the liquid pump 122 extends into the interior of the hollow frame 121. The interior of the hollow frame 121 is a hollow outer frame, and the hollow interior can store anti-corrosion liquid. The liquid pump 122 draws the anti-corrosion spraying liquid and sprays it out from the spray plates 123 to achieve processing and protection of the moving heat pipe.
[0030] Please see Figure 4 The drying assembly 13 includes a drying chamber 131 fixedly connected to the upper side of the processing plate 1, a ventilation hole 132 opened on the upper side of the drying chamber 131, a fan 133 disposed on the inner wall of the ventilation hole 132, an air inlet frame 134 fixedly connected to the drying chamber 131, and a heating pipe 135 fixed on the inner wall of the air inlet frame 134. The fan 133 blows air downward through the ventilation hole 132 and then heats the air through the ventilation hole 132, thereby raising the temperature of the flowing air and improving the drying effect.
[0031] Please see Figure 1 A protective net 14 is fixedly connected to the upper side of the air intake frame 134, and multiple support legs 15 are fixedly connected to the lower side of the treatment plate 1. During the air intake process, the protective net 14 filters dust to prevent dust from directly affecting the pipe, and the support legs 15 are used to support the weight of the treatment plate 1.
[0032] The implementation principle of the anti-corrosion treatment device for the surface of a ground source heat pump heat pipe in this embodiment is as follows: During use, the ground source heat pump heat pipe is first placed between the lower pressure shaft 404 and the conveying shaft 302. The heat pipe is tightened and clamped by activating the electric telescopic rod 402 to press the lower pressure frame 403 and the lower pressure shaft 404. The stepper motor 305 on the extension plate 304 drives the synchronous wheel 306 to rotate. The synchronous belt 307 enables the conveying shafts 302 at both ends to rotate synchronously, achieving synchronous conveying of the pipe. During the heat pipe conveying process, the pipe… The material passes through the interior of the hollow frame 121, and the anti-corrosion material inside the hollow frame 121 is extracted by the liquid pump 122 and sprayed out through the spray plate 123 to spray the moving heat pipe. The interior of the hollow frame 121 is hollow and carries the heated anti-corrosion coating. The input end of the liquid pump 122 extends into the hollow frame 121 to extract the coating. Then, as the material moves along the inner wall of the drying chamber 131, the heating pipe 135 heats up, and the fan 133 draws air from the ventilation hole 132 to blow hot air into the drying chamber 131 for drying.
[0033] After tensioning, just before the anti-corrosion coating is to be sprayed, the drive motor 9 is started to drive the drive gear 10 to rotate. Then the drive gear 10 drives the driven gear 11 and the rotating ring 7 to rotate, so that the scraper 8 contacts the outside of the pipe, thereby scraping away the sludge and impurities on the moving outer wall of the pipe, creating a relatively flat surface on the outside of the heat pipe, so that the spraying equipment can more evenly cover the anti-corrosion coating on the pipe and ensure the uniformity of the coating.
[0034] By rotating the adjusting screw 17 in the adjusting groove 16, the adjusting block 18 is moved to a certain position inside the adjusting groove 16, thereby causing the scraper 8 to tighten to different degrees, so as to be applicable to pipes of different diameters and improve the applicability of pipe treatment.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
