Description

Technical Field

[0001] This application relates to the technical field of pipe coating, and in particular discloses a pipe coating drying device. Background Technology

[0002] Spraying is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets by pressure or centrifugal force and apply them to the surface of the object being coated.

[0003] After coating, existing pipes often need to be dried to ensure the quality and performance of the coating. However, existing drying equipment can only dry the coating on the outer or inner side of the pipe, resulting in a limited range of applications and making it unsuitable for drying different parts of the pipe. Utility Model Content

[0004] In order to expand the application range of drying equipment, this application provides a pipe coating drying device.

[0005] This application provides a pipe coating drying device, which adopts the following technical solution:

[0006] A pipe coating drying device includes a conveying channel, a first gantry frame, an outer drying component, a second gantry frame, a lifting component, and an inner drying component. The conveying channel is equipped with a conveying component for conveying pipes, and the first gantry frame is installed on the top of the conveying channel.

[0007] The external drying assembly includes a first fan and an external drying pipe. The first fan is fixed to the upper surface of the first portal frame. One end of the external drying pipe is fixed to the air outlet of the first fan. The other end of the external drying pipe passes through the first portal frame and is located between the conveying channel and the first portal frame. A first air outlet is provided on the side of the external drying pipe between the conveying channel and the first portal frame.

[0008] The first portal frame has an opening on its upper surface for the inner drying assembly to enter. The second portal frame is fixed above the first portal frame. The lifting assembly is installed on the second portal frame and is used to lift the inner drying assembly. The inner drying assembly includes a mounting plate, a second fan, and an inner drying pipe. The mounting plate is fixed to the lifting end of the lifting assembly. The second fan is installed on the mounting plate. One end of the inner drying pipe is fixed to the air outlet of the second fan. The other end of the inner drying pipe is closed. The inner drying pipe has a second air outlet.

[0009] By adopting the above technical solution, the lifting component drives the inner drying component to move upward, so that the pipe can pass through the conveying channel below the inner drying component and enter the outer drying component, enabling the equipment to dry the coating layer on the outer side of the pipe; the lifting component drives the inner drying component to move downward, so that the inner drying component can enter the conveying channel and the pipe can enter the inner drying component, enabling the equipment to dry the coating layer on the inner side of the pipe, thus expanding the application range of the drying equipment.

[0010] Optionally, a first resistance heater is installed on the outer drying tube outside the first gantry frame.

[0011] By adopting the above technical solution, the first resistance heater can heat the gas inside the outer drying tube, thereby accelerating the drying speed of the outer drying component.

[0012] Optionally, the lifting assembly includes a hydraulic cylinder and a lifting plate. The hydraulic cylinder is fixed to the outer top surface of the second portal frame, and the lifting end of the hydraulic cylinder passes through the second portal frame. The lifting plate is slidably connected inside the second portal frame and is fixed to the lifting end of the hydraulic cylinder.

[0013] By adopting the above technical solution, the hydraulic cylinder is activated, which can drive the lifting plate to rise and fall, facilitating the lifting and lowering of the internal drying components.

[0014] Optionally, the mounting plate is rotatably connected to a rotating disk, and the second fan is fixed on the rotating disk. The rotating disk is driven to rotate by a drive assembly, which includes a drive motor, a gear, and an external gear ring. The drive motor is fixed on the side of the mounting plate away from the inner drying tube, the gear is fixed at the output end of the first drive motor, and the external gear ring is fixed on the rotating disk and meshes with the gear.

[0015] By adopting the above technical solution, the drive motor is started, which drives the gear to rotate. The rotation of the gear drives the outer gear ring to rotate, thereby causing the rotating disk to rotate, which in turn drives the inner drying tube to rotate, thus improving the uniformity of drying of the inner drying component.

[0016] Optionally, a second resistance heater is installed at one end of the inner drying tube near the rotating disk, and the second resistance heater is fixed to the side of the rotating disk.

[0017] By adopting the above technical solution, the second resistance heater can heat the gas inside the inner drying tube, thereby accelerating the drying speed of the inner drying component.

[0018] Optionally, the lifting end of the lifting assembly is also fixed with a heat insulation plate, and the inner drying tube is rotatably connected to the heat insulation plate. The heat insulation plate separates the second resistance heater from the second air outlet on the inner drying tube.

[0019] By adopting the above technical solution, the heat insulation plate separates the second resistance heater from the second air outlet on the inner drying tube, reducing the impact of the hot air ejected from the inner drying tube on the second resistance heater and improving the service life of the second resistance heater.

[0020] Optionally, the opening of the first portal frame is located at the end of the first portal frame, and a sliding groove is provided on the end face of the first portal frame at the opening, and a partition plate capable of separating the opening is slidably connected on the sliding groove.

[0021] By adopting the above technical solution, when the coating layer on the outer side of the drying pipe of the external drying component is dried, inserting the partition plate into the groove at the opening can reduce the heat loss in the first gantry frame and improve the drying effect of the external drying component.

[0022] Optionally, the internal drying assembly is provided in two sets, and the two sets of internal drying assemblies are symmetrically arranged on the first portal frame.

[0023] By adopting the above technical solution, the coating layer on the inner wall of two pipes can be dried simultaneously, thus improving the drying efficiency.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] The lifting component moves the inner drying component upward, allowing the pipe to pass through the conveying channel below the inner drying component and enter the outer drying component, enabling the equipment to dry the coating layer on the outer side of the pipe; the lifting component moves the inner drying component downward, allowing the inner drying component to enter the conveying channel and the pipe to enter the inner drying component, enabling the equipment to dry the coating layer on the inner side of the pipe, thus expanding the application range of the drying equipment.

[0026] The drive motor can drive the gear to rotate, the gear to rotate the outer gear ring, which in turn causes the rotating disk to rotate, thereby driving the inner drying tube to rotate and improving the uniformity of drying of the inner drying component.

[0027] The heat insulation plate separates the second resistance heater from the second air outlet on the inner drying tube, reducing the impact of the hot air ejected from the inner drying tube on the second resistance heater and improving the service life of the second resistance heater.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a pipe coating drying device. (Refer to...) Figure 1 A pipe coating drying device includes a conveying channel 1, a first gantry frame 2, an outer drying component 3, a second gantry frame 4, a lifting component 5, and an inner drying component 6. The opening of the first gantry frame 2 faces downward and is fixed to the upper surface of the conveying channel 1. Two second gantry frames 4 are provided, and the openings of the two second gantry frames 4 face downward. The two second gantry frames 4 are fixed to both ends of the upper surface of the first gantry frame 2.

[0035] Reference Figure 1 and Figure 2 A conveying assembly 11 for conveying pipelines is installed inside the conveying channel 1. The conveying assembly 11 includes an electric guide rail 111, a slide plate 112, a vertical plate 113, a fixing plate 114, a bidirectional screw 115, and a clamping plate 116. Two electric guide rails 111 are provided, and the two electric guide rails 111 are symmetrically fixed in the conveying channel 1 by bolts. The slide plate 112 is fixed to the slider of the electric guide rail 111 by bolts. The vertical plate 113 is fixed to the upper surface of the slide plate 112. Two fixing plates 114 are provided. The two fixing plates 114 are fixed at intervals on the side of the vertical plate 113. The bidirectional screw 115 is rotatably connected between the two fixing plates 114, and the top end of the bidirectional screw 115 has a hexagonal rotating groove. Two clamping plates 116 are provided in each set, and the two clamping plates 116 are respectively threaded to both sides of the bidirectional screw 115, and both clamping plates 116 are slidably connected to the side of the vertical plate 113.

[0036] Reference Figure 1 and Figure 2Before applying the coating to the outer wall of the drying pipe, the pipe is placed outside two clamping plates 116. The double-acting screw 115 is rotated, causing the two clamping plates 116 to press against the inner wall of the drying pipe, thus fixing the pipe. The electric guide rail 111 is then activated, allowing the pipe to enter the outer drying assembly 3, thereby drying the coating on the outer wall of the pipe. Before applying the coating to the inner wall of the drying pipe, a set of sliders is added to the other end of the electric guide rail 111. A sliding plate 112, a vertical plate 113, the double-acting screw 115, and the clamping plates 116 are installed on the sliders added to the electric guide rail 111. The pipe is placed between the two clamping plates 116, and the double-acting screw 115 is rotated, causing the two clamping plates 116 to press against the outer wall of the drying pipe, thus fixing the pipe. The electric guide rail 111 is then activated, allowing the pipe to enter the inner drying assembly 6, thereby drying the coating on the inner wall of the pipe.

[0037] Reference Figure 1 and Figure 3 An external drying assembly 3 is installed on the first portal frame 2 and is located between two second portal frames 4. The external drying assembly 3 includes a first fan 31, an external drying pipe 32, and a first resistance heater 33. The first fan 31 is fixed to the upper surface of the first portal frame 2. One end of the external drying pipe 32 is fixed to the air outlet of the first fan 31, and the other end of the external drying pipe 32 passes through the first portal frame 2 and is located between the conveying channel 1 and the first portal frame 2. The external drying pipe 32 located between the conveying channel 1 and the first portal frame 2 is composed of multiple spiral tubes and two straight tubes connected together. Multiple first air outlets are opened on the side of the external drying pipe 32 located between the conveying channel 1 and the first portal frame 2. The first resistance heater 33 is fixedly installed on the upper surface of the first portal frame 2 and is connected to the external drying pipe 32. The first fan 31 and the first resistance heater 33 can blow heated gas to the first air outlet of the outer drying pipe 32. The outer wall coating of the outer drying pipe 32 can be quickly dried by the hot air blown out of the outer drying pipe 32, which facilitates the rapid drying of the outer wall coating.

[0038] Reference Figure 1 and Figure 4 Two sets of lifting components 5 are provided, each mounted on one of the two second portal frames 4. Each lifting component 5 includes a hydraulic cylinder 51 and a lifting plate 52. Two hydraulic cylinders 51 are provided, fixed at intervals to the outer top surface of the second portal frame 4. The lifting ends of the hydraulic cylinders 51 pass through the second portal frame 4. The lifting plate 52 is slidably connected within the second portal frame 4 and is fixed to the lifting ends of the hydraulic cylinders 51. Activating the hydraulic cylinders 51 causes the lifting plate 52 to rise or fall.

[0039] Reference Figure 1 and Figure 4The upper surface of the first portal frame 2 has openings at both second portal frames 4 for the inner drying assembly 6 to pass through. The end face of the first portal frame 2 has sliding grooves on both sides of the openings. A partition plate 9, capable of separating the openings, is slidably connected to the first portal frame 2 along the sliding grooves. When the coating layer on the outer side of the drying pipe of the outer drying assembly 3 passes through, inserting the partition plate 9 into the sliding groove at the opening reduces heat loss within the first portal frame 2 and improves the drying effect of the outer drying assembly 3.

[0040] Reference Figure 1 and Figure 4 Two sets of internal drying components 6 are provided, each mounted on one of two lifting plates 52. Each internal drying component 6 includes a mounting plate 61, a second fan 62, an internal drying pipe 63, a rotating disk 64, and a second resistance heater 65. The mounting plate 61 is fixed to the bottom surface of the lifting plate 52. The rotating disk 64 is rotatably connected to the mounting plate 61. The second fan 62 is fixed to one side of the rotating disk 64. One end of the internal drying pipe 63 is fixedly installed at the outlet of the second fan 62, and the other end of the internal drying pipe 63 passes through the rotating disk 64. The end of the internal drying pipe 63 facing away from the second fan 62 is closed, and a second air outlet is provided on the side of the internal drying pipe 63 facing away from the second fan 62. The second resistance heater 65 is fixed to the side of the rotating disk 64 facing away from the second fan 62 and is connected to the internal drying pipe 63. A heat insulation plate 8, rotatably connected to the internal drying pipe 63, is also fixedly installed on the bottom surface of the lifting plate 52. The heat insulation plate 8 separates the second resistance heater 65 from the second air outlet on the inner drying tube 63. This reduces the impact of the hot air ejected from the inner drying tube 63 on the second resistance heater 65 and extends its service life.

[0041] Reference Figure 1 and Figure 4 A drive assembly 7 for driving the rotating disk 64 is mounted on the mounting plate 61. The drive assembly 7 includes a drive motor 71, a gear 72, and an external gear ring 73. The drive motor 71 is fixed to the side of the mounting plate 61 opposite to the inner drying tube 63, and the output end of the drive motor 71 passes through the mounting plate 61. The gear 72 is fixed to the output end of the first drive motor 71, and the external gear ring 73 is fixed to the outer side of the rotating disk 64, and the external gear ring 73 meshes with the gear 72. When the inner drying assembly 6 is drying the coating layer on the inner wall of the drying pipe, the drive motor 71 is started. The drive motor 71 drives the gear 72 to rotate, the gear 72 drives the external gear ring 73 to rotate, and the external gear ring 73 drives the rotating disk and the inner drying tube 63 to rotate, thereby improving the drying uniformity of the inner drying assembly 6.

[0042] The principle of a pipe coating drying device according to an embodiment of this application is as follows: When drying the coating on the outer wall of the pipe, the hydraulic cylinder 51 drives the inner drying component 6 to rise. After the inner drying component 6 rises into the second portal frame 4, the partition plate 9 is inserted into the opening of the first portal frame 2. The pipe is transported to the outer drying component 3 by the conveying component 11, and the hot air blown out from the outer drying pipe 32 can quickly dry the coating on the outer wall of the pipe. When drying the coating on the inner wall of the pipe, a set of sliders is added to the other end of the electric guide rail 111, and a sliding plate 112, a vertical plate 113, a bidirectional screw 115, and a clamping plate 116 structure are installed on the sliders added to the electric guide rail 111. At the same time, the partition plate 9 at the opening of the first portal frame 2 is removed. After the partition plate 9 at the opening of the first portal frame 2 is removed, the hydraulic cylinder 51 is started, and the hydraulic cylinder 51 drives the inner drying component 6 to descend. After the inner drying component 6 descends into the first gantry frame 2, the drive motor 71 and the second fan 62 are started. The pipeline is transported to the inner drying component 6 through the conveying component 11. The hot air blown out from the inner drying pipe 63 can quickly dry the coating layer on the inner wall of the pipeline.

[0043] 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.
