Description

Technical Field

[0001] This utility model relates to the field of paint mist recovery technology, and in particular to a light-cured paint mist recovery device. Background Technology

[0002] UV-curable coatings, due to their outstanding advantages such as fast curing speed, low volatile organic compound content, low energy consumption, and excellent coating performance, have been increasingly widely used in coating production in industries such as automobiles, furniture, electronics, and metal processing. Their curing mechanism mainly relies on the polymerization reaction of photoinitiators under ultraviolet light irradiation of a specific wavelength, thereby achieving instantaneous curing of the coating. In spray painting operations, regardless of the degree of automation, the phenomenon of "overspraying" exists, where some paint fails to effectively adhere to the workpiece surface, forming suspended mist-like particles in the air, i.e., "paint mist." Existing paint mist systems recover this mist using paint mist recovery equipment.

[0003] For example, document CN212216012U discloses a dual centrifugal spray paint mist recovery device, which describes "including an oil collection spray chamber shell, an oil mist recovery device installed inside the oil collection spray chamber shell, the spray recovery device including dual centrifugal fans, an oil slinger and an oil receiving tank, an inner frame welded inside the oil collection spray chamber shell, a fixing plate installed on the inner frame, the fixing plate being fixed to the inner frame by bolts, the oil slinger being fixed to the fixing plate, the dual centrifugal fans being fixedly connected to the inner frame and installed inside the oil slinger, a shell base welded to the bottom of the oil collection spray chamber shell, and the oil receiving tank being fixed to the shell base by bolts." This device can effectively recover spray paint mist, improve the utilization rate of paint, is environmentally friendly, and greatly reduces production costs.

[0004] Existing paint mist recovery equipment uses gas-liquid separation turbines to separate paint mist. Because the motor and gas-liquid separation wheel are located inside the equipment casing, a large amount of paint mist adheres to the motor and transmission mechanism, causing the motor speed to decrease and affecting the paint mist separation efficiency. In addition, the power supply needs to be connected to the casing, which poses a great safety hazard since paint mist is flammable and explosive. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] As attached Figure 1 To be continued Figure 6 As shown:

[0025] A UV-curing paint mist recovery device includes a support frame 1, an mounting frame 2 fixedly mounted on the upper surface of the support frame 1, side plates 3 fixedly connected to both sides of the mounting frame 2, a top plate 4 fixedly connected to the top of the mounting frame 2, a mounting base 11 fixedly mounted on the upper surface of the top plate 4, a motor 14 fixedly mounted on the upper surface of the mounting base 11, an output shaft 12 fixedly connected to the output end of the motor 14, a rotating shaft 17 connected to the output shaft 12 via a synchronous belt drive, a gas-liquid separator wheel 13 fixedly sleeved at the other end of the rotating shaft 17, the rotating shaft 17 and the gas-liquid separator wheel 13 being located below the top plate 4, an mounting plate 6 fixedly mounted inside the mounting frame 2, an opening 7 on the outer wall of the mounting plate 6, an oil slinger 8 fixedly mounted at the opening 7 on the mounting plate 6, the gas-liquid separator wheel 13 being located inside the oil slinger 8, an oil receiving groove 9 provided on the lower surface of the mounting frame 2, and an oil drain hole 10 provided at the bottom of the oil receiving groove 9.

[0026] In the above technical solution, during the paint spraying process on the workpiece, the motor 14 starts, driving the output shaft 12 to rotate. The output shaft 12 drives the rotating shaft 17 to rotate via a synchronous belt. The rotating shaft 17 drives the gas-liquid separator wheel 13 to rotate at high speed. When the paint mist comes into contact with the gas-liquid separator wheel 13, due to the adsorption coating on the surface of the gas-liquid separator wheel 13, the paint mist will condense into a liquid under the action of centrifugal force and be thrown onto the inner wall of the oil slinger 8 by the gas-liquid separator wheel 13. Subsequently, the condensed liquid paint mist will flow with the oil slinger 8 to the oil receiving tank 9 under the action of gravity, and flow out through the oil drain hole 10 on one side of the oil receiving tank 9, thus completing the recovery of the paint mist.

[0027] It is worth mentioning that the motor 14 is the power source of the equipment and is electrically connected to the external power source. The motor 14 is set on the upper surface of the top plate 4 and outside the mounting bracket 2, thereby avoiding the influence of paint mist and improving the safety performance.

[0028] The mounting bracket 2 has a protective shell 15 inside, which is located inside the oil slinger 8. The rotating shaft 17 is rotatably connected to the protective shell 15, and the synchronous belt at the rotating shaft 17 is located inside the protective shell 15.

[0029] In the above technical solution, through the design of the protective shell 15, the protective shell 15 protects the synchronous belt and other transmission components, reduces the contact between the transmission components and paint mist, and improves the working time and service life of the transmission components.

[0030] There are multiple mounting bases 11, motors 14, output shafts 12, protective shells 15, rotating shafts 17, oil slingers 8, and gas-liquid separators 13. These multiple mounting bases 11, motors 14, output shafts 12, protective shells 15, rotating shafts 17, oil slingers 8, and gas-liquid separators 13 are all arranged at equal intervals along the horizontal direction of the top plate 4. There are multiple oil receiving grooves 9, which are arranged at equal intervals along the horizontal direction of the mounting frame 2. The oil receiving grooves 9 correspond to the oil slingers 8.

[0031] In the above technical solution, there are multiple motors 14 and gas-liquid separation wheels 13. Multiple sets of gas-liquid separation wheels 13 are arranged at equal intervals. Multiple sets of gas-liquid separation wheels 13 can operate simultaneously to improve separation efficiency. Moreover, a single motor 14 controls a single gas-liquid separation wheel 13. When one motor 14 fails, it does not affect the operation of other gas-liquid separation wheels 13.

[0032] A protective cover 5 is fixedly installed on the upper surface of the top plate 4, and the motor 14 is located inside the protective cover 5.

[0033] In the above technical solution, the protective cover 5 is designed to protect the motor.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In use, during the painting process on the workpiece, the motor 14 starts, driving the output shaft 12 to rotate. The output shaft 12 drives the rotating shaft 17 to rotate via a synchronous belt. The rotating shaft 17 drives the gas-liquid separator wheel 13 to rotate at high speed. When the paint mist comes into contact with the gas-liquid separator wheel 13, due to the adsorption coating on the surface of the gas-liquid separator wheel 13, the paint mist will condense into a liquid under the action of centrifugal force and be thrown onto the inner wall of the oil slinger 8 by the gas-liquid separator wheel 13. Subsequently, the condensed liquid paint mist will flow with the oil slinger 8 to the oil receiving tank 9 under the action of gravity, and flow out through the oil drain hole 10 on one side of the oil receiving tank 9, thus completing the recovery of the paint mist.

[0036] Please refer to the above structure and process. Figure 1-6 .

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
