In the process of ship painting, the overspray mist produced by airless spraying releases a large amount of toxic substances, which seriously endangers the health of the spray painters. At the same time, the substances scattered in the air pollute the ecological environment. Most of the existing technologies use spray booths to recycle overspray mist, which lacks certain convenience and is not suitable for the scene of high-altitude spraying of ships. Summary of the invention

[0003] In order to solve the above technical problems, the present application provides an overspray paint mist recovery device suitable for ship painting, which can recover the scattered paint mist and reduce pollution.

[0004] The present application provides an overspray mist recovery device suitable for ship painting, which adopts the following technical solution: An overspray mist recovery device suitable for ship painting, comprising: A support frame for mounting the spray gun assembly; The recovery cover comprises a mounting portion, a vacuum adsorption portion and a first recovery pipe, wherein the mounting portion is used to connect the spray gun head of the spray gun assembly, the vacuum adsorption portion is a frame-type structure, a vacuum hole is provided on the inner side of the vacuum adsorption portion, the first recovery pipe connects the mounting portion and the vacuum adsorption portion and is in communication with the vacuum hole, and the mounting portion and the vacuum adsorption portion are arranged in a staggered manner; The recovery box is provided with a second recovery pipe for connecting to the mounting portion on the outside, the second recovery pipe is connected to the first recovery pipe, and the recovery box is provided with a stirring mechanism for stirring and mixing the paint mist flocculant and the recovered paint mist.

[0005] By adopting the above technical scheme, the recovery hood is installed on the spray gun head through the mounting part, the vacuum adsorption part of the frame structure is provided with a vacuum hole, and is connected to the mounting part through the first recovery pipe, and the vacuum pump provides adsorption force for the vacuum hole. When the ship is spraying paint, the spray gun sprays paint mist toward the surface of the ship, and the overspray paint mist collides with the surface of the ship and rebounds and dissipates in all directions. The vacuum hole adsorbs the dissipated paint mist, which can quickly capture the dissipated paint mist during the spraying operation, reduce the paint mist dissipation rate, and improve the recovery efficiency.

[0006] Optionally, the vacuum adsorption portion is an annular frame, an annular groove is provided on the inner side of the annular frame, and the vacuum hole is located in the annular groove.

[0007] By adopting the above technical solution, the annular frame design makes the vacuum holes more evenly distributed, thereby improving the capture efficiency of paint mist. The design of the annular groove can effectively concentrate the paint mist, reduce the deposition of paint mist on the inner wall of the recovery hood, avoid affecting the workers' line of sight, and ensure the spraying quality and safe operation.

[0008] Optionally, the inner side wall and the bottom of the annular groove together define a right-angle structure, and the bottom of the annular groove is recessed toward the vacuum adsorption hole.

[0009] By adopting the above technical scheme, the inner wall and the bottom of the annular groove jointly define a right-angle structure, so that the area around the vacuum hole forms a stable space, and the paint mist gathered in the groove is not easy to flow out of the groove, which is beneficial to improving the concentration and stability of the paint mist during the suction process. The bottom of the annular groove is recessed toward the vacuum adsorption hole, which further increases the suction area, improves the suction efficiency, and reduces the possibility of paint mist escaping. This structure optimizes the collection path of the paint mist, ensuring that the paint mist can be more effectively sucked into the recovery device, thereby improving the recovery effect of the entire device.

[0010] Optionally, the mounting portion is provided with an extension nozzle for connecting the spray gun head, the middle portion of the mounting portion has a circumferential connecting portion, the extension nozzle passes through the circumferential connecting portion and extends between the vacuum adsorption portion and the mounting portion.

At the same time, the extended nozzle is passed through the circumferential connection part, which enhances the overall stability and reliability of the structure, avoids the deviation of the spray gun caused by improper operation or external factors, and improves the spraying quality and work efficiency.

[0012] Optionally, the mounting portion is provided with a control valve, and the control valve is used to adjust the suction force of the vacuum hole, and the control valve is an electrically driven automatic valve.

[0013] By adopting the above technical scheme, the control valve can accurately adjust the suction of the vacuum hole, thereby ensuring that overspray paint mist can be effectively recovered under different spraying conditions, preventing excessive deposition of paint mist on the surface of the recovery hood and affecting the workers' field of vision, while ensuring the spraying quality and efficiency. The electrically driven automatic valve can achieve precise control of the suction of the vacuum hole. In actual operation, the suction force can be adjusted in real time according to different painting operation requirements to ensure the effective recovery of paint mist without affecting the spraying quality and efficiency. In addition, automated control improves the operating convenience and intelligence level of the equipment, reduces the need for manual intervention, and further improves the safety and reliability of work.

[0014] Optionally, the recovery cover is provided with a plurality of hollow structures, and the hollow structures are located between the mounting portion and the vacuum adsorption portion.

[0015] By adopting the above technical solution, the recovery hood is provided with multiple hollow structures, which are located between the mounting part and the vacuum adsorption part. These hollow structures can effectively reduce the weight of the recovery hood, improve the overall lightness and flexibility of the device, and facilitate the operator to operate it when working at high altitudes. At the same time, the hollow structure can also enhance the air circulation inside and outside the recovery hood, which helps prevent paint mist from condensing on the surface of the recovery hood during the recovery process, thereby maintaining a good field of vision and ensuring the smooth progress of the painting work. In addition, the hollow design also helps to reduce the impact of the recovery hood on the spraying area and improve the spraying accuracy and quality.

[0016] Optionally, the support frame is provided with a slide rail, and the spray gun assembly is movably arranged on the slide rail, and the slide rail includes a transverse slide rail and a longitudinal slide rail.

[0017] By adopting the above technical solution, the support frame is provided with a slide rail, and the spray gun assembly is movably arranged on the slide rail, and the slide rail includes a transverse slide rail and a longitudinal slide rail. This design allows the spray gun assembly to be flexibly moved in multiple directions, ensuring that a larger spraying area can be covered during high-altitude spraying operations, thereby improving the uniformity and coverage of the spraying. At the same time, the multi-directional movement capability also improves the flexibility of operation, reduces the time and labor intensity of manual adjustment, and improves work efficiency.

[0018] Optionally, the support frame is provided with a turntable, and the spray gun assembly is mounted on the turntable and can rotate along a vertical plane.

[0019] By adopting the above technical solution, the spray gun assembly can be flexibly rotated in the vertical plane to ensure that the spray gun maintains the best angle with the surface to be sprayed, thereby improving the spraying quality and work efficiency. The design of the turntable allows the operator to quickly adjust the position of the spray gun according to actual needs, reducing the time and labor intensity of manual adjustment, and improving the safety and convenience of the spraying operation.

[0020] Optionally, a through hole is provided on the top of the recovery box, and an exhaust device is connected to the through hole.

[0022] Optionally, the recycling box is a cylindrical structure, and the stirring mechanism includes three-lobed stirring blades, and the three-lobed stirring blades are evenly arranged around the central axis of the recycling box.

[0023] By adopting the above-mentioned technical solution, overspray paint mist can be effectively introduced into the recovery box, and the three-petal stirring blades are evenly arranged around the central axis of the recovery box to ensure that the paint mist and the paint mist flocculant are fully mixed, thereby improving the flocculation effect of the paint mist. This design not only improves the recovery efficiency, but also makes it easier for the paint mist to form solid sediments during the recovery process, which is convenient for subsequent salvage and reuse, thereby reducing environmental pollution and saving resources. At the same time, the cylindrical structure design helps to maintain a stable stirring effect, further improving the quality of paint mist treatment.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0029] At present, in the process of ship painting, the overspray mist produced by airless spraying releases a large amount of toxic substances, which seriously endangers the health of spray painters, and the substances scattered in the air pollute the ecological environment. To this end, this application mainly adopts an overspray mist recovery device suitable for ship painting, including a support frame, a recovery cover and a recovery box, which achieves the effect of effectively capturing and processing overspray mist, which not only protects the health of workers but also reduces environmental pollution.

[0030] The present application is further described in detail below in conjunction with the accompanying drawings.

[0031] Reference Figure 1 As shown, an embodiment of the present application provides an overspray mist recovery device suitable for ship painting, including a support frame 1, a recovery cover 3 and a recovery box 8.

[0032] It should be noted that the spray gun assembly 2 includes a spray gun 21 and a paint can 22, which are connected by a pipeline, and the paint is transported from the paint can 22 to the spray gun 21. The support frame 1 is used to install the spray gun assembly 2 to ensure the stability of the spray gun 21 of the spray gun assembly 2 during high-altitude operations.

[0033] Reference Figure 1 As shown, the support frame 1 is provided with a slide rail 13, and the slide rail 13 includes a transverse slide rail 13 and a longitudinal slide rail 13. The support frame 1 also includes a turntable 14, and the turntable 14 is movably mounted on the slide rail 13. The paint can 22 of the spray gun assembly 2 is mounted on the turntable 14 and can rotate along a vertical plane. The spray gun assembly 2 is installed on the aerial spraying operation vehicle through the support frame 1. Such a design allows the spray gun assembly 2 to be adjusted in all directions during the spraying operation, thereby improving the uniformity and coverage of the spraying, thereby improving the quality and efficiency of the spraying. A rotating shaft is provided at the center of the turntable 14, which is driven by a motor to achieve circumferential rotation.

[0034] The diameter of the turntable 14 can be selected according to actual needs. It is usually recommended to use a turntable 14 with a larger diameter to facilitate a larger spray coverage area. The rotation speed of the turntable 14 can be adjusted by a frequency converter to adapt to different spray speeds and coating thicknesses.

[0035] The turntable 14 can also be equipped with a position sensor to monitor the position information of the spray gun assembly 2 in real time, and realize accurate spraying path planning through a feedback control system, which can significantly improve the spraying quality and reduce paint waste.

[0036] The transverse slide rail 13 can ensure that the spray gun assembly 2 and the recovery cover 3 move horizontally during the spraying operation, and the longitudinal slide rail 13 can ensure that the spray gun assembly 2 and the recovery cover 3 move longitudinally during the spraying operation. The spray gun assembly 2 can move freely in multiple directions during the spraying operation, which increases the flexibility and accuracy of the spraying. Among them, both the transverse slide rail 13 and the longitudinal slide rail 13 can adopt high-precision linear guide rails to ensure smooth movement and accurate positioning. The turntable 14 can be made of high-strength aluminum alloy, which is light and durable.

[0037] Reference Figure 1 and Figure 2 As shown, the recovery cover 3 includes a mounting portion 4, a vacuum adsorption portion 5 and a first recovery pipe 7. The mounting portion 4 is used to connect the spray gun 21 head of the spray gun assembly 2, the vacuum adsorption portion 5 is a frame-type structure, and a vacuum hole 6 is provided inside, the first recovery pipe 7 connects the mounting portion 4 and the vacuum adsorption portion 5, and is connected to the vacuum hole 6, the mounting portion 4 and the vacuum adsorption portion 5 are arranged front and back in a staggered manner, so that the escaped paint mist will not float to the position of the mounting portion 4, and at the same time, this design enables the recovery cover 3 to effectively capture the escaped paint mist without affecting the line of sight of the painter.

[0038] The vacuum adsorption part 5 of the recovery cover 3 can adopt an annular frame structure, and an annular groove is provided on the inner side of the annular frame, and the vacuum hole 6 is located in the annular groove. Such a design helps to distribute the suction more evenly and improve the paint mist recovery efficiency. The inner side wall and the bottom of the annular groove together define a right-angle structure, and the bottom of the annular groove is recessed toward the vacuum adsorption hole. The inner side wall and the bottom of the annular groove together define a right-angle structure, so that the area around the vacuum adsorption hole 6 forms a stable space, and the paint mist gathered in the groove is not easy to flow out of the groove, which is beneficial to improve the concentration and stability of the paint mist during the suction process. The bottom of the annular groove is recessed toward the vacuum adsorption hole, which can guide the paint mist accumulated in the annular groove to flow to the vacuum adsorption hole.

[0039] In addition, the mounting portion 4 is provided with an extension nozzle 11 for connecting the head of the spray gun 21, and the extension nozzle 11 is arranged in the middle of the mounting portion 4 and has a circumferential connection portion, extending between the vacuum adsorption portion 5 and the mounting portion 4. In this way, the spray gun 21 can be well matched with the recovery cover 3, thereby improving the overall working efficiency.

[0040] The mounting portion 4 is provided with a control valve 12 for adjusting the suction force of the vacuum hole 6. The control valve 12 can be a manually regulated manual valve or an electrically driven automatic valve to adapt to different working environments and requirements. For example, an electrically driven automatic valve can automatically adjust the suction force according to actual needs, thereby improving the convenience and accuracy of operation.

[0041] In addition, the recovery cover 3 may also be provided with a plurality of hollow structures, which are located between the mounting portion 4 and the vacuum adsorption portion 5. The design of the hollow structure not only reduces the weight of the recovery cover 3, but also improves the ventilation effect, reduces the residence time of the paint mist in the recovery cover 3, and further improves the recovery efficiency.

[0042] Reference Figure 1 As shown, the outside of the recovery box 8 is provided with a second recovery pipe 9 for connecting to the mounting portion 4, and the inside is provided with a stirring mechanism 10 for stirring and mixing the paint mist flocculant and the recovered paint mist. A through hole is provided on the top of the recovery box 8, and an exhaust device is connected to the through hole. The recovery box 8 is a cylindrical structure, and the stirring mechanism 10 includes three-lobed stirring blades, and the three-lobed stirring blades are evenly arranged around the central axis of the recovery box 8. This design allows the paint mist to be fully mixed and reacted in the recovery box 8 to form solid sediments, and the clean gas is discharged through the exhaust device on the top to ensure that the recovered air is safe and harmless.

[0043] The internal stirring mechanism 10 of the recycling box 8 can be driven by a motor to achieve continuous stirring and improve the effect of paint mist flocculation. A removable end cover is provided at the through hole. This design can maintain a stable airflow during the recycling process and avoid high-pressure gas from causing harm to workers.

[0044] The length and width of the stirring blade can be reasonably designed according to the size of the recycling box 8 to ensure the best stirring effect. The material of the stirring blade can be selected from wear-resistant and corrosion-resistant stainless steel or other high-performance alloys to extend the service life. The surface of the stirring blade can be polished to reduce resistance and improve stirring efficiency.

[0045] The stirring mechanism 10 can also be equipped with a temperature sensor and a pH sensor to monitor the reaction conditions in the recovery box 8 in real time to ensure the best reaction effect of the paint mist flocculant. The temperature and pH data can be sent to the control terminal through a wireless transmission module to achieve remote monitoring and management.

[0046] The through hole is configured as a circular small hole, and there are multiple through holes. This design can evenly disperse the exhausted gas and reduce the risk of excessive local pressure. The movable end cover can be closed when exhaust is not required to prevent external impurities from entering the recovery box 8 and affecting the recovery effect.

[0047] The diameter of the through hole is generally 1-2 mm, and the number is set according to actual needs. The removable cover can be designed with quick disassembly for easy maintenance and cleaning. The material of the end cover can be selected from a high temperature resistant and corrosion resistant metal alloy to ensure long-term use without damage.

[0048] The exhaust device can also be equipped with a filter to intercept larger particles and prevent them from being discharged with the gas and polluting the environment. The replacement cycle of the filter can be regularly checked and replaced according to actual conditions to ensure the continuous and efficient operation of the system.

[0049] During use, after the vacuum pump is turned on, the vacuum pump will provide suction for the recovery cover 3, and the suction of the recovery cover 3 is controlled by rotating the controllable valve on the recovery cover 3. After the airless spray gun 21 is turned on, the paint mist on the periphery escapes, and the vacuum adsorption part 5 of the recovery cover 3 approaches the escaped paint mist and sucks the paint mist. The sucked paint mist enters the stirring tank of the recovery box 8, and the stirring mechanism 10 starts to work. After stirring, the paint residue solids are precipitated, and the clean gas is discharged, completing the recovery and reuse of the paint mist.

[0050] Through the suction provided by the vacuum pump, the recovery hood 3 effectively captures the overspray paint mist during the painting process and transports it to the recovery box 8. In the recovery box 8, the paint mist reacts chemically with the flocculant to form solid sediments, and the clean gas is discharged through the exhaust device to ensure that the air quality meets the standard. This process not only improves the recovery rate of paint mist, but also reduces environmental pollution and improves the working environment.

[0051] By simulating the painting operation scene without the device installed, the airless spraying in the painting operation will generate 30%-50% paint mist escape. By simulating the painting operation scene after the device is installed, the device can reduce the escape rate to 6%-10%, the recovery effect is relatively good, and the spraying efficiency will not be greatly affected. The feasibility of the stirring pool recycling is verified by simulating the stirring process of the stirring pool in the recovery box 8.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
