[0001] The utility model relates to the technical field of anti-corrosion pipeline processing equipment, in particular to an epoxy powder spraying device for 3PE anti-corrosion pipes. Background Art
[0002] At the end of the anti-corrosion steel pipe processing process, it is necessary to spray anti-corrosion coatings on its inner wall. At present, for the spraying of the inner wall of some large-diameter steel pipes, the method of manual entry is mostly used. This method belongs to confined space operation, and it is difficult for personnel to operate and has certain risks, with low efficiency. Moreover, this method is not applicable to steel pipes whose inner diameter does not meet the requirements for personnel entry, and has great limitations.
[0003] In view of the above technical problems, the utility model patent with the publication number of CN 220406059U discloses an inner wall spraying device for anti-corrosion pipelines, including a track, a painting trolley and a support trolley arranged on the track; a paint bucket, a paint pump and a wire threading pipe are arranged on the painting trolley. One end of the wire threading pipe is provided with a rotary spray head, and the paint pump is connected with a paint delivery pipe. The paint delivery pipe penetrates into the wire threading pipe and is connected with the rotary spray head; an I-shaped wheel is arranged on the top of the support trolley, and the painting trolley is connected with the support trolley and adjacent support trolleys respectively through stay wires; during operation, first insert the wire threading pipe into the steel pipe and then start to withdraw it at a constant speed. During the withdrawal process, the rotary spray head sprays paint at the same time, thereby completing the spraying operation of the inner wall of the steel pipe. There is no human participation in the whole process of advancing and withdrawing, and the long wire threading pipe can be effectively supported at any time and will not deform.
[0004] However, in the actual application process of this technical solution, when the rotary spray head extends into the steel pipe to spray powder on the steel pipe, due to the certain pressure of the sprayed epoxy powder, powder dust will be generated inside the steel pipe and flow out from both ends of the steel pipe, which not only pollutes the production workshop, but also affects the health of workers.
