Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe processing equipment, specifically to a device for coating anti-corrosion layers on steel pipes. Background Technology

[0002] Steel pipes are widely used in the transportation of natural gas, urban water, heating networks, and water supply and drainage. They have an outer circumference.

[0003] After the steel pipe is manufactured, an outer coating is formed on its outer periphery. The outer coating has the effect of preventing corrosion of the steel pipe. The equipment used to form an outer coating on the steel pipe is a steel pipe anti-corrosion coating device.

[0004] The aforementioned steel pipe anti-corrosion coating device includes a frame with a rotating roller and a traveling roller driven by an electric motor. In use, the steel pipe is placed on the rotating roller and the traveling roller. The rotating roller rotates the steel pipe, and the traveling roller moves the steel pipe forward. During use, the steel pipe moves from back to front on the frame. The frame also has nozzles for spraying anti-corrosion material flux. These nozzles can form a layer of anti-corrosion material flux on the outside of the steel pipe. Once the flux solidifies, it forms an anti-corrosion material layer on the outside of the steel pipe. In existing technologies, due to improper nozzle placement, the anti-corrosion layer formed on the steel pipe is prone to developing ridges, affecting the smoothness of the anti-corrosion layer and product quality. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned shortcomings by providing a steel pipe anti-corrosion coating device that produces a smooth anti-corrosion layer with high product quality.

[0006] The technical solution of this utility model is implemented as follows: a steel pipe anti-corrosion coating device includes a frame, on which are driven by a motor to rotate a roller and a traveling roller. In use, the steel pipe is placed on the rotating roller and the traveling roller. The rotating roller is the wheel on which the steel pipe on it rotates, and the traveling roller is the wheel on which the steel pipe on it moves forward. In use, the steel pipe moves from back to front on the frame. A nozzle for anti-corrosion material flux is also installed on the frame. The nozzle is connected to a pipeline for conveying the anti-corrosion material solvent. The nozzle can form a layer of anti-corrosion material flux on the outside of the steel pipe. When the flux solidifies, it forms an anti-corrosion material layer on the outside of the steel pipe. The part of the nozzle facing the steel pipe is the coating forming part. The characteristic is that the nozzle is installed between the center of the horizontal steel pipe and the topmost part of the steel pipe.

[0007] Preferably, the nozzle is installed at the 10-11 o'clock position.

[0008] Preferably, there are multiple nozzles, which are mounted on the frame from front to back.

[0009] Furthermore, the distance between adjacent nozzles is greater than or equal to the distance the steel pipe travels in one revolution on the frame.

[0010] Furthermore, the part of the spray nozzle that sprays the coating onto the steel pipe is the coating formation part. This device also includes a refrigeration device with a cold air outlet, which is installed in front of the coating formation part facing the steel pipe.

[0011] The beneficial effects of this utility model are: such a steel pipe anti-corrosion coating device has the advantages of good anti-corrosion layer flatness and high product quality. Attached Figure Description

[0017] The present invention will now be further described with reference to the accompanying drawings.

[0018] like Figure 1 , 2As shown in Figures 3 and 4, the steel pipe anti-corrosion coating device includes a frame 1, on which are mounted a rotating roller 2 driven by an electric motor and a traveling roller 3. In use, a steel pipe 4 is placed on the rotating roller and the traveling roller. The rotating roller rotates the steel pipe, and the traveling roller moves the steel pipe forward. During use, the steel pipe moves from back to front on the frame; arrow F in the figure points forward. A nozzle 5 for the anti-corrosion material flux is also installed on the frame. The nozzle is connected to a conveying pipe 6 for the anti-corrosion material solvent. The nozzle can form a layer of anti-corrosion material flux on the outside of the steel pipe. Upon solidification, the flux forms an anti-corrosion material layer on the outside of the steel pipe. The part of the nozzle facing the steel pipe is the coating forming part. The characteristic feature is that the nozzle is installed between the horizontal center position O of the steel pipe and the uppermost part P of the steel pipe.

[0019] The nozzle is installed between the horizontal center position O of the steel pipe and the uppermost part P of the steel pipe, that is, between the 9 and 12 o'clock positions.

[0020] The present invention is designed such that the anti-corrosion material layer formed on the steel pipe is essentially solidified when the steel pipe rotates downwards, preventing or reducing the formation of protrusions, thus achieving the purpose of the present invention.

[0021] The nozzle is installed between the center position O of the steel pipe and the uppermost part P of the steel pipe, that is, between the horizontal plane and the vertical plane of the center position of the steel pipe.

[0022] Preferably, the nozzle is installed at the 10-11 o'clock position.

[0023] Viewed from the front, the direction of rotation of the steel pipe corresponds to the direction of rotation of the clock hand. Figure 2 , 3 In line 4, the direction of arrow D is the direction of the steel pipe rotation. The part that the nozzle is pointing at is equivalent to the 10-11 o'clock position, which is more effective in reducing the formation of ridges.

[0024] Preferably, there are multiple nozzles (51, 52, 53), which are mounted on the frame from front to back.

[0025] This design allows for multiple applications of the anti-corrosion material flux, resulting in a better reduction in the formation of raised lines.

[0026] Furthermore, the distance between adjacent nozzles is greater than or equal to the distance the steel pipe travels in one revolution on the frame.

[0027] This design ensures that the next coating is applied after the steel pipe has rotated once, resulting in a higher quality anti-corrosion material layer.

[0028] Furthermore, the part of the spray nozzle that sprays the coating onto the steel pipe is the coating formation part. This device also includes a cooling device 8, which has a cold air outlet 9, which is installed in front of the coating formation part and faces the steel pipe.

[0029] Furthermore, the air conditioning outlet includes a first air conditioning outlet 91, which is located at position 1-2.

[0030] Furthermore, the air conditioning outlet includes a second air conditioning outlet 92, which is located at the 4-5 o'clock position.

[0031] Furthermore, the air conditioning outlet includes a third air conditioning outlet 93, which is located at the 6 o'clock position.

[0032] This invention is designed in such a way that it can accelerate the formation of the anti-corrosion material layer.

[0033] Preferably, the refrigeration device and the cold air blown out by the cold air outlet can make the surface temperature of the steel pipe reach 10-15°C.

[0034] Preferably, the size of the multiple nozzles decreases sequentially from back to front. That is, the amount of anti-corrosion material solvent that can be sprayed from the nozzle decreases from back to front.

[0035] This design results in a higher quality anti-corrosion material layer.

[0036] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
