[0002] In the manufacturing and maintenance of large industrial facilities such as ships, chemical tanks, and wind turbine towers, high-altitude, large-area spraying operations are an indispensable and crucial step.

[0003] During spray painting, some paint tends to form paint mist that drifts into the air, while other paint, once in the air, easily drips onto the surface of the workpiece substrate, creating difficult-to-treat runs or uneven spots. Traditional methods often use simple shielding materials for localized protection, but this structure cannot actively capture the paint mist drifting in the air. Another problem is that paint easily adheres to the inner wall of this shield, and after accumulation, it may fall off, causing secondary pollution. Utility Model Content

Detailed Implementation

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0019] Please refer to the following: Figure 1 and Figure 2 .like Figure 1 As shown, the paint recovery system includes an escape paint mist recovery mechanism 1, a drip paint recovery mechanism 2, and a protective cover 3. The protective cover 3 surrounds the work area of ​​the spraying operation and is used to shield the paint generated during the spraying operation. The escape paint mist recovery mechanism 1 and the drip paint recovery mechanism 2 are respectively installed on the protective cover 3. The escape paint mist recovery mechanism 1 is used to recover the escape paint mist generated during the spraying operation, and the drip paint recovery mechanism 2 is used to recover the dripping paint that falls or collects on the protective cover 3.

[0020] Please refer to the following: Figures 1 to 5As shown in the figure, the paint mist recovery mechanism 1 includes four suction pipes (including a first suction pipe 11, a second suction pipe 12, a third suction pipe 13, and a fourth suction pipe 14), two suction hoods (including a first suction hood 15 and a second suction hood 16), two manifold tee pipes (a first manifold tee pipe 17 and a first manifold tee pipe 18), two flexible hoses (not shown), a filter box 19, and a fan 10. The paint mist is discharged through the four suction pipes, the filter box 19, and the fan 10.

[0021] The four suction pipes are positioned above the steel plate being sprayed to remove paint mist that drifts into the air. The four suction pipes are arranged symmetrically in a rectangular shape. Specifically, the first suction pipe 11 and the second suction pipe 12 are located on the left side of the spraying area, the third suction pipe 13 and the fourth suction pipe 14 are located on the right side of the spraying area, the first suction pipe 11 and the third suction pipe 13 are located in front of the spraying area, and the second suction pipe 12 and the fourth suction pipe 14 are located behind the spraying area.

[0022] To facilitate more efficient introduction of escaping paint mist into the suction pipes, a suction hood is provided at the inlet of each suction pipe. The first suction hood 15 is located at the inlet of the first suction pipe 11 and the inlet of the second suction pipe 12, and the second suction hood 16 is located at the inlet of the third suction pipe 13 and the inlet of the fourth suction pipe 14. Preferably, the vertical cross-section of the first suction hood 15 and the second suction hood 16 is trapezoidal, narrow at the top and wide at the bottom.

[0023] Preferably, the four suction pipes and the two suction hoods have large diameters, which is beneficial for capturing paint mist. At the same time, this can prevent large particles of paint mist from clogging the air ducts and eliminate the need for short-term cleaning, thus reducing the frequency of maintenance.

[0024] The outlet of the first suction pipe 11 is connected to the outlet of the third suction pipe 13, and is connected to the first inlet of the fan 10 through the first manifold tee 17. The outlet of the second suction pipe 12 is connected to the outlet of the fourth suction pipe 14, and is connected to the second inlet of the fan 10 through the second manifold tee 18. The inlet of the filter box 19 is provided with a first connecting pipe 191 and a second connecting pipe 192. The outlet of the first manifold tee 17 is connected to the first connecting pipe 191 through a first flexible hose (not shown), and the outlet of the second manifold tee 18 is connected to the second connecting pipe 192 through a second flexible hose (not shown).

[0025] For a compact design, the fan 10 is mounted on the filter box 19. The filter box 19 has a filter element, so that the escaping paint mist will not clog the fan 10 after filtration. Preferably, the fan 10 is a ducted fan.

[0026] Please refer to the following: Figure 1 , Figure 2 , Figure 6 as well as Figure 7 The dripping paint recovery mechanism 2 includes a paint flow channel 21, a paint collection tank 22, a gear pump 23, a pressure relief valve 24, and a paint recovery container 25. Dripping paint formed on the protective cover 3 flows into the paint collection tank 22 via the paint flow channel 21. The paint in the paint collection tank 22 is then pumped into the paint recovery container 25 by the gear pump 23. The pressure relief valve 24 is located between the gear pump 23 and the paint recovery container 25 to prevent excessive pressure inside the paint recovery container 25 from causing an explosion.

[0027] Preferably, the gear pump 23 and the paint recycling tank 25 are connected by a hose with an inner diameter of 120mm and made of PVC.

[0028] The paint guide channel 21 and the paint collection channel 22 are grooves in shape, and both are located at the bottom of the protective cover 3. The paint guide channel 21 includes a first paint guide channel 211 and a second paint guide channel 212, which are respectively located on the two long sides of the bottom of the protective cover 3. The paint collection channel 22 is located on one narrow side of the bottom of the protective cover 3. The dripping paint flows from the first paint guide channel 211 and the second paint guide channel 212 into the paint collection channel 22.

[0029] Please refer to the following: Figure 1 , Figure 2 as well as Figure 7 The frame of the shield 3 is an aluminum alloy frame, and the skin of the shield 3 is made of carbon fiber plate and ABS plastic. Understandably, the shield 3 is a specially designed structure to facilitate the installation of the escaping paint mist recovery mechanism 1 and the dripping paint recovery mechanism 2.

[0030] The working method of this utility model is as follows: During the spraying operation, the protective cover 3 is installed on the chassis of the spraying robot, and the escaping paint mist recovery mechanism 1 and the dripping paint recovery mechanism 2 are respectively installed on the protective cover 3. When the spraying robot is working, the paint is atomized and sprayed from the high-pressure spray gun and coated on the surface of the steel plate. At this time, excess paint mist is generated and escapes to both sides along the surface of the steel plate. The fan 10 starts to work, and under the suction force generated by the fan, the escaping paint mist generated by the spraying operation is recovered into the filter box 19 through the four suction pipes. The dripping paint or paint that drips or collects on the protective cover 3 is drawn into the paint recovery tank 25 through the paint guide channel 21, the paint collection tank 22, and the gear pump 23.

[0031] This invention achieves active and efficient source capture of paint mist, effectively preventing paint mist escape and secondary pollution. Unlike traditional passive shielding or vacuum pump solutions with narrow inlets, this application, by setting a large-diameter air inlet and air duct, combined with the stable negative pressure generated by the ducted fan, can achieve wide-range and high-efficiency source capture of overspray paint mist dynamically escaping along the steel plate surface to both sides. This design not only significantly improves the paint mist recovery rate, reduces paint waste and environmental pollution, but also makes the large-diameter air duct less prone to clogging by larger paint mist particles, reducing maintenance frequency and equipment failure risk.

[0032] This utility model innovatively integrates a dripping paint recovery function, solving the problems of paint waste and drip pollution. The dripping paint recovery mechanism 2 actively collects liquid paint that drips or collects on the protective cover 3 during operation and recovers it to a tank via a pumping system, achieving paint recycling and directly reducing material costs. More importantly, this mechanism prevents dripping paint from forming drips or bumps on the workpiece surface, reducing the workload of subsequent sanding and touch-up spraying, and significantly improving coating quality and operational efficiency.

[0033] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
