Description

Technical Field

[0001] This utility model relates to the field of steel-plastic composite pipe spraying technology, specifically to an internal spraying device for steel-plastic composite pipes. Background Technology

[0002] The steel-plastic composite pipe internal spraying device is a special equipment used to uniformly spray anti-corrosion, wear-resistant or functional coatings onto the inner wall of steel-plastic composite pipes. It is used for the mass production of anti-corrosion and wear-resistant coatings on the inner wall of steel-plastic composite pipes, and can also be used to spray and repair the inner wall of aging or damaged pipes, extending their service life.

[0003] Existing composite pipe internal spraying devices, such as the pipe internal wall spraying device disclosed in publication number CN219702404U, have the advantage of spraying the inner walls of pipes with different inner diameters. However, this spraying device is inconvenient to uniformly clean, wipe and remove impurities from the inner wall of the pipe before spraying. As a result, the presence of impurities on the inner wall of the pipe can easily affect the spraying effect. Therefore, we propose a steel-plastic composite pipe internal spraying device.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, the brush bristles and wiping pads installed on the outer ring and fixed ring at the rear end of the sprayer can uniformly and thoroughly brush away and wipe away dust and impurities from the inner wall of the steel-plastic composite pipe before the sprayer moves into the pipe for inner wall spraying. This avoids the spraying effect being affected by impurities during the inner wall spraying of the steel-plastic composite pipe. The cleaning roller driven by the motor on one side of the platform can also clean the wiping pad after use, preventing a large amount of impurities from remaining at the outer end and thus preventing them from falling into the inner wall of the steel-plastic composite pipe during the return spray head of the sprayer.

[0015] 2. In this utility model, the rubber pad driven by the electric push rod at the top of the placement platform can also press the steel-plastic composite pipe on the placement platform during cleaning, thereby ensuring the stability of the inner wall of the steel-plastic composite pipe during cleaning.

When the sprayer 105 is moved into the steel-plastic composite pipe, the brush bristles 205 and wiping pad 203 at its rear end can clean and wipe the inner wall of the steel-plastic composite pipe, and the dust and impurities cleaned and wiped are pushed away by the wiping pad 203 and the fixing ring 202. After the wiping pad 203 is removed from the steel-plastic composite tube, it will move to the outer end of the cleaning roller 206. At this time, the cleaning roller 206 will be rotated by the motor 208 to clean the dust and impurities remaining on the outer end of the wiping pad 203. After the wiping pad 203 is cleaned, the electric slide rail 102 will move the sprayer 105 back to spray the inner wall of the steel-plastic composite tube. When the wiping pad 203 in the fixing ring 202 is dirty, it can also be disassembled for cleaning or replacement through the Velcro 211 at its inner end and the Velcro 210 at the inner end of the fixing ring 202.
