Description

Technical Field

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

[0002] In spraying operations, regardless of the degree of automation, there is always an "overspray" phenomenon, which means that some paint fails to adhere effectively to the surface of the workpiece, thus forming suspended mist-like particles in the air, namely "paint mist". Existing paint mist is recovered through 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

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example:

[0031] As attached Figure 1 To be continued Figure 11 As shown:

[0032] A highly stable paint mist recovery device includes a support frame 1. A mounting shell 2 is fixedly connected to the upper surface of the support frame 1. A motor 9 is fixedly mounted on the upper surface of the mounting shell 2. An output shaft 10 is fixedly connected to the output end of the motor 9. Multiple drive shafts 11 are rotatably mounted on the upper surface of the mounting shell 2, equidistant from each other along the horizontal direction of the mounting shell 2. Each drive shaft 11 is connected to the output shaft 10 via bevel gears. A first synchronous pulley 12 is fixedly sleeved on the other end of each drive shaft 11. A synchronous belt 13 is sleeved on the outer wall of the first synchronous pulley 12. A through hole 8 is provided at the top of the mounting shell 2. The mounting shell 2 is positioned at the through hole 8. A protective shell 14 is provided, and the other end of the protective shell 14 extends into the interior of the mounting shell 2 through the through hole 8. The other end of the protective shell 14 is rotatably connected to a rotating shaft 19. One end of the rotating shaft 19 is sleeved with a second synchronous pulley 21. The second synchronous pulley 21 is sleeved with the other end of the synchronous belt 13. The other end of the rotating shaft 19 passes through and extends to the outside of the protective shell 14. The extended end of the rotating shaft 19 is fixedly sleeved with a gas-liquid separator wheel 18. A mounting plate 4 is fixedly installed inside the mounting shell 2. The outer wall of the mounting plate 4 has a mounting opening 15. An oil slinger 16 is fixedly installed on the mounting plate 4 at the mounting opening 15. The gas-liquid separator wheel 18 is located inside the oil slinger 16.

[0033] In the above technical solution, when the workpiece is sprayed with paint, the motor 9 is started, the motor 9 drives the output shaft 10 to rotate, the output shaft 10 drives the transmission shaft 11 to rotate through the bevel gear, the transmission shaft 11 drives the first synchronous pulley 12 to rotate, the first synchronous pulley 12 drives the rotating shaft 19 to rotate through the synchronous belt 13 and the second synchronous pulley 21, the rotating shaft 19 drives the gas-liquid separator wheel 18 to rotate at high speed. When the paint mist comes into contact with the gas-liquid separator wheel 18, the paint mist will fall on the outer surface of the gas-liquid separator wheel 18. The paint mist will condense into liquid under the action of centrifugal force and be thrown onto the inner wall of the oil slinger 16 by the gas-liquid separator wheel 18. Then the liquid paint mist will flow downward under the action of gravity.

[0034] It is worth mentioning that the motor 9 is the power source of the device and is electrically connected to the external power source. The motor 9, output shaft 10 and transmission shaft 11 are set on the upper surface of the mounting shell 2, outside the mounting shell 2, so as to avoid being affected by paint mist and improve safety performance.

[0035] In the above technical solution, there are multiple gas-liquid separation wheels 18, which are equidistantly arranged so that they can be driven to work synchronously by the motor 9 in the mounting shell 2, thereby improving the separation efficiency.

[0036] Furthermore, through the transmission of bevel gears and synchronous belt 13, the output shaft 10 drives multiple transmission shafts 11 to rotate via bevel gears, and the transmission shafts 11 drive the rotating shaft 19 to rotate via synchronous belt 13. The rotating shaft 19 drives the gas-liquid separator wheel 18 to rotate, thus enabling multiple gas-liquid separator wheels 18 to rotate through one power source.

[0037] An opening 5 is provided on the lower surface of the mounting shell 2. An oil receiving hopper 6 is fixedly connected to the mounting shell 2 at the opening 5. An oil drain hole 7 is provided at the bottom of the oil receiving hopper 6. There are multiple oil receiving hoppers 6, which are arranged at equal intervals along the horizontal direction of the mounting shell 2. The oil receiving hoppers 6 correspond to the oil slinger 16.

[0038] In the above technical solution, the liquid paint mist will flow to the oil receiving hopper 6 along with the oil slinger 16 under the action of gravity, and will flow out through the oil drain hole 7 on one side of the oil receiving hopper 6, thus completing the recycling of the paint mist.

[0039] A protective cover 3 is fixedly installed on the upper surface of the mounting housing 2, and the motor 9, output shaft 10, and transmission shaft 11 are all located inside the protective cover 3.

[0040] In the above technical solution, through the design of the protective cover 3, the protective cover 3 can protect the motor 9, the output shaft 10, and the transmission shaft 11.

[0041] A U-shaped frame 17 is fixedly installed on the rear side of the mounting plate 4. The U-shaped frame 17 is located at the bottom of the protective shell 14. A bearing sleeve 20 is fixedly installed on the outside of the U-shaped frame 17. The outer wall of the middle part of the rotating shaft 19 is fixedly connected to the inner part of the bearing sleeve 20.

[0042] In the above technical solution, the U-shaped frame 17 is fixedly connected to the mounting plate 4. Through the design of the U-shaped frame 17 and the bearing sleeve 20, the rotating shaft 19 is rotatably connected to the U-shaped frame 17 through the bearing sleeve 20, which can ensure that the rotating shaft 19 has good rotational performance during rotation and improve the service life and stability of the entire rotating assembly.

[0043] The specific usage and function of this embodiment are as follows:

[0044] When this utility model is used, during the painting process on the workpiece, the motor 9 is started, and the motor 9 drives the output shaft 10 to rotate. The output shaft 10 drives the transmission shaft 11 to rotate through the bevel gear. The transmission shaft 11 drives the first synchronous pulley 12 to rotate. The first synchronous pulley 12 drives the rotating shaft 19 to rotate through the synchronous belt 13 and the second synchronous pulley 21. The rotating shaft 19 drives the gas-liquid separator wheel 18 to rotate at high speed. When the paint mist comes into contact with the gas-liquid separator wheel 18, the paint mist will fall on the outer surface of the gas-liquid separator wheel 18. Under the action of centrifugal force, the paint mist will condense into liquid and be thrown onto the inner wall of the oil slinger 16 by the gas-liquid separator wheel 18. Subsequently, it will condense into liquid paint mist. Under the action of gravity, the liquid paint mist will flow with the oil slinger 16 to the oil collecting hopper 6 and flow out through the oil drain hole 7 on one side of the oil collecting hopper 6, thus completing the recovery of the paint mist.
