[0021] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other, as described above. Figures 1-5 .

[0022] Reference Figures 1-3 To solve the technical problems of this technical solution, This invention provides an assemblable recyclable spray nozzle assembly, comprising a fixed semicircular ring 1 and a movable semicircular ring 2 hinged to one end of the fixed semicircular ring 1 and forming a circular structure together with the fixed semicircular ring 1. The inner sides of the fixed semicircular ring 1 and the movable semicircular ring 2 are provided with a plurality of independent and multi-directionally adjustable micro-nozzles 3. The fixed semicircular ring 1 has a fixed end, and the fixed end of the fixed semicircular ring 1 is connected to a connecting pipe 4. The outer end of the connecting pipe 4 is used to connect to a spray slurry supply source. Each micro-nozzle 3 is connected to the connecting pipe 4 and, through the connecting pipe 4, to the spray slurry supply source to achieve the function of spraying slurry. In this embodiment, the fixed semicircular ring 1 and the movable semicircular ring 2 are provided with external liquid supply pipelines, or the fixed semicircular ring 1 and the movable semicircular ring 2 are provided with internal liquid supply channels. The connecting pipe 4 is connected to multiple micro-nozzles 3 through the external liquid supply pipelines or the internal liquid supply channels, and the slurry supplied by the spraying slurry supply source is sprayed out through the external liquid supply pipelines or the internal liquid supply channels. Specifically, the spraying slurry supply source is usually a commercial spray gun, which delivers slurry to multiple micro-nozzles 3. In some other embodiments, other slurry supply sources can also be used as spraying slurry supply sources depending on the specific implementation. In addition, in this embodiment, the connecting pipe 4 is a threaded pipe, which serves as a connection function and as one section of the slurry delivery channel.

[0023] Reference Figure 2 , Figure 3 The movable semicircular ring 2 has a connecting end and is hinged to the fixed end of the fixed semicircular ring 1 through the connecting end. The free end of the fixed semicircular ring 1 is detachably connected to the free end of the movable semicircular ring 2, so that the fixed semicircular ring 1 and the movable semicircular ring 2 form a detachable ring. The inner sidewalls of the fixed semicircular ring 1 and the movable semicircular ring 2 are provided with a recycling system for recycling slurry. In practical applications, utilizing the detachable nature of the fixed semicircular ring 1 and the movable semicircular ring 2, when a component needs to be fitted, simply detach the free end of the fixed semicircular ring 1 from the free end of the movable semicircular ring 2, and then rotate the movable semicircular ring 2 around its hinge axis to open the ring. At this point, the component to be painted can be easily fitted using the fixed semicircular ring 1 and the movable semicircular ring 2. After the component is in place, rotating the movable semicircular ring 2 aligns its free end with the free end of the fixed semicircular ring 1, forming a ring structure. The component to be painted is then conveniently fitted into the ring. Compared to existing painting equipment, this significantly reduces assembly difficulty, offers better flexibility and versatility, greatly improves work efficiency, and reduces equipment and labor costs.

[0024] On the other hand, in this technical solution, the micro nozzles 3 are independent of each other and can be adjusted in multiple directions. By utilizing the independent adjustable function of the micro nozzles 3, the spraying direction of each nozzle can be adjusted as needed, which helps to eliminate spraying dead angles and improve spraying quality.

[0025] Furthermore, the recycling system can recover the slurry wasted during the spraying process, reducing slurry waste and environmental pollution, making it more economical and environmentally friendly.

[0026] Reference Figure 1 , Figure 5 In some specific embodiments, the recycling system includes multiple return holes 5 disposed on the inner sidewalls of the fixed semicircular ring 1 and the movable semicircular ring 2. The fixed semicircular ring 1 and the movable semicircular ring 2 are provided with external recycling pipes or have internal recycling channels. The external recycling pipes or the internal recycling channels are connected to the return holes 5 and used to transport the slurry recovered from the return holes 5 to an external slurry recycling container. Specifically, during the micro-nozzle spraying process, slurry that falls onto the inner walls of the fixed semicircular ring 1 and the movable semicircular ring 2 flows into the external recycling pipes or the internal recycling channels through the return holes 5. The recovered slurry is further returned to the slurry recycling container through the external recycling pipes or the internal recycling channels for secondary use. To facilitate the smooth recovery of slurry into the slurry recovery container, a negative pressure source can be installed. This source provides negative pressure to the external recovery pipe, the internal recovery channel, and the return hole 5, allowing the return hole 5 to effectively draw away the slurry from the inner walls of the fixed semi-circular ring 1 and the movable semi-circular ring 2. Thus, when slurry that has fallen onto the inner walls of the fixed semi-circular ring 1 and the movable semi-circular ring 2 flows to the vicinity of the inlet of the return hole 5 under gravity, the negative pressure from the negative pressure source allows for faster absorption by the return hole 5, improving recovery efficiency.

[0027] Reference Figure 5 In some specific embodiments, the fixed semicircular ring 1 and the movable semicircular ring 2 are provided with a return micro-slope structure on their inner walls near the return hole 5 to facilitate the return of paint to the return hole 5. This return micro-slope structure forms a recessed area around the return hole 5, allowing the slurry in the inner walls of the fixed semicircular ring 1 and the movable semicircular ring 2 to converge at the recessed area. This ensures that residual paint is automatically guided into the return hole 5 under gravity, further improving the efficiency of slurry recovery.

[0028] Reference Figure 5In addition, a removable sealing bolt 51 is provided at each of the return holes 5. The operator can open only the most advantageous return holes 5 to connect to the recycling system, depending on the component's orientation and spraying direction, while keeping the remaining return holes 5 sealed to avoid unnecessary flow resistance and system leakage. This flexible orifice management mechanism further enhances the operability and system stability of the device under different construction postures.

[0029] In some specific embodiments, the recycling system further includes side baffles (not shown in the figure) disposed on the side walls of the fixed semicircular ring 1 and the movable semicircular ring 2. The side baffles extend towards the center of the fixed semicircular ring 1 and the movable semicircular ring 2, forming a groove structure with the inner walls of the fixed semicircular ring 1 and the movable semicircular ring 2 to accommodate the slurry. Specifically, the side baffles can be folded plates bent towards the center of the sides of the fixed semicircular ring 1 and the movable semicircular ring 2, or additionally welded external panels; the appropriate method can be selected according to implementation needs. The side baffles prevent slurry falling onto the inner walls of the fixed semicircular ring 1 and the movable semicircular ring 2 from leaking from the sides of the fixed semicircular ring 1 and the movable semicircular ring 2 and contaminating adjacent components, further improving the slurry recycling rate, reducing waste and pollution, and improving economic efficiency.

[0030] In some specific embodiments, the micro-nozzles 3 are mounted on the inner walls of the fixed semicircular ring 1 and the movable semicircular ring 2 via a multi-directional adjustment device (not shown in the figure). The multi-directional adjustment device can adjust the spray direction of the micro-nozzles 3 in the vertical, forward / backward, left / right, and radial directions. In this embodiment, there are six micro-nozzles 3. The multi-directional adjustment device can be used to adjust the micro-nozzles 3 in the vertical, forward / backward, left / right, and radial directions according to the cross-sectional shape and curvature of the component being sprayed, thereby optimizing the spraying angle and distance and ensuring uniform coating thickness. Through independent nozzle adjustment, this device is compatible with various truss cross-sections (including square steel, round pipes, C-shaped steel, and I-beams), significantly improving the adaptability and spraying flexibility of the equipment. Furthermore, in this technical solution, each micro-nozzle 3 has a built-in independent nozzle switch. The independent nozzle switch allows for the opening or closing of the corresponding nozzle for different component conditions, enabling targeted spraying and further enhancing spraying flexibility.

[0031] In some specific embodiments, the fixed end of the fixed semi-circular ring 1 is provided with a fixed base plate 11 and is fixedly connected to the connecting pipe 4 through the fixed base plate 11. The connecting end of the movable semi-circular ring 2 is provided with a hinge seat 21 and is hinged to the fixed base plate 11 of the fixed semi-circular ring 1 through the hinge seat 21. The free end of the fixed semi-circular ring 11 is provided with a fixed semi-circular ring free end connecting plate 12, and the free end of the movable semi-circular ring 2 is provided with a movable semi-circular ring free end connecting plate 22 adapted to the fixed semi-circular ring free end connecting plate 12. The fixed semi-circular ring free end connecting plate 12 and the movable semi-circular ring free end connecting plate 22 are detachably connected by end bolts 6. The fixed semi-circular ring 1 and the movable semi-circular ring 2 are metal components or other components that can meet sufficient strength requirements.

[0032] Based on the above-described assembled recyclable spray nozzle assembly, the present invention also provides: A spraying system includes the aforementioned assembled recyclable spray nozzle assembly, a spray slurry supply source, and a slurry recovery container. The spray slurry supply source is connected to the micro-nozzle 3 via a connecting pipe, and the slurry recovery container is used in conjunction with the recovery system. In application, the spray slurry supply source provides slurry, which is then delivered to the micro-nozzle 3 via the connecting pipe 4. Slurry that falls onto the inner walls of the fixed semi-circular ring 1 and the movable semi-circular ring 2 during the spraying process is recovered by the recovery system. The recovered slurry is stored in the slurry recovery container for reuse, resulting in good economic efficiency and environmental friendliness.

[0033] The above is a detailed description of the preferred embodiments of the present invention. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention.
