Description

Technical Field

[0001] This invention relates to the field of paint separation technology, and more particularly to a mechanism for separating atomized paint. Background Technology

[0002] Spray painting is a coating method that uses a spray gun or disc atomizer to disperse paint into uniform and fine droplets using pressure or centrifugal force, and then applies the paint to the surface of the object being coated. During spray painting, paint escapes into the air and requires purification treatment.

[0003] In existing spray booths, most use water curtains to absorb paint from the air. Specifically, the air in the spray booth passes through the water curtain, and the paint naturally dissolves into the water. This method has the disadvantage of high water consumption, and the water needs to be purified afterward. If the paint accumulates and solidifies, it will cause blockage of the wastewater treatment equipment. Summary of the Invention

[0004] To address the aforementioned problems, this invention discloses a mechanism for separating atomized paint, comprising a housing, inside which a rotating shaft is disposed, and an oil-slinging disc is sleeved on the rotating shaft. Driving the rotating shaft to rotate causes the oil-slinging disc to rotate accordingly. When air containing paint passes through the oil-slinging disc, the disc traps the atomized paint and flings it onto the interior of the housing, thus achieving the purpose of separating the paint from the air.

[0005] The outer casing includes a sleeve with an expanded diameter section at its front end. The oil slinger includes an outer connecting ring and an inner connecting sleeve. Several rods are fixedly connected to both sides of the inner connecting sleeve at equal angles, and the other end of each rod is fixedly connected to one side of the outer connecting ring. That is, the rods are arranged in two layers. This arrangement increases the contact area with air, which is beneficial for improving paint separation. If the two layers of rods were combined into one layer, it would affect air permeability.

[0006] The outer diameter of the outer connecting ring is larger than the inner diameter of the sleeve and smaller than the inner diameter of the expansion section. The outer connecting ring fits inside the expansion section. When air passes through the outer casing, the expansion section is in a "windless zone." After the paint is thrown onto the inner wall of the expansion section, the airflow is small, and the paint does not easily cure. This ensures that the paint flows down from the front end of the mechanism, avoiding the need to regularly clean the inner wall of the outer casing.

[0007] Preferably, the rotating shaft includes a first mating section and a second mating section, with a protruding ring between the first and second mating sections. The inner connecting sleeve is sleeved on the first mating section. Furthermore, a flat key is provided between the inner connecting sleeve and the first mating section to ensure stable rotation of the inner connecting sleeve with the rotating shaft.

[0008] Preferably, a support sleeve is provided inside the sleeve, and the second mating section is rotatably fitted onto the support sleeve. A limit nut is threadedly connected to one side of the second mating section, and the limit nut, in conjunction with a convex ring, clamps the support sleeve. The rotating shaft is restricted to the support sleeve by the limit bolt and the convex ring. Furthermore, to ensure smooth rotation of the rotating shaft, a bearing or bushing can be provided between the second mating section and the support sleeve.

[0009] Preferably, a plurality of support rods are fixedly connected to the side wall of the support sleeve at equal angles, and the other end of each support rod is fixedly connected to the inner wall of the sleeve. The support sleeve is fixedly connected to the inside of the sleeve by the support rods.

[0010] Preferably, one end of the first mating section is fixedly connected to a threaded section, and an end cap is threadedly connected to the threaded section, with the end cap screwed tightly to press against the oil slinger. The end cap and threaded section prevent axial movement of the oil slinger.

[0011] Preferably, one end of the second mating section is fixedly connected to a coupling section, and the coupling section is hollow. The side wall of the coupling section is threaded with a fixing bolt. The coupling section is used to connect the relevant drive mechanism, and the driving mechanism is stably connected by the fixing bolt. The drive mechanism is a structure used to drive the rotating shaft to rotate.

[0012] Preferably, the side wall of the sleeve is fixedly connected with a plurality of connecting ears, and the connecting ears are provided with through holes. The separation mechanism is fixed in the working area through the connecting ears.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. Equipped with an oil-slinging tray, which can trap atomized paint in the air and throw it into the expansion section under the action of centrifugation. Since the air flow in the expansion section is small, the paint can flow away from the lower front of the mechanism before curing, avoiding interference caused by paint curing. Water can be eliminated during the process.

[0015] 2. The oil slinger has two layers of rods, which increases the contact area with air while having little impact on air permeability, thus facilitating efficient paint separation. Attached Figure Description

[0023] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] like Figures 1 to 4 As shown, a mechanism for separating atomized paint includes a housing 1, which is cylindrical in shape. A rotating shaft 4 is installed inside the housing 1, and the two are arranged coaxially. An oil-slinging disc 2 is sleeved on the rotating shaft 4. During operation, the oil-slinging disc 2 rotates with the rotating shaft 4. As air passes through the housing 1, the atomized paint is trapped by the oil-slinging disc 2 and thrown onto the inner wall of the housing 1, thus achieving separation.

[0025] The outer casing 1 includes a sleeve 11, and the front end of the sleeve 11 is provided with an expanded diameter section 12, that is, the diameter of the expanded diameter section 12 is larger than the diameter of the sleeve 11. The oil slinger 2 includes an outer connecting ring 21 and an inner connecting sleeve 23. Several rods 22 are fixedly connected at equal angles on both sides of the inner connecting sleeve 23, that is, the rods 22 are fixedly connected in two layers. The other end of each rod 22 is fixedly connected to one side of the outer connecting ring 21. The double-layer rods 22 greatly increase the contact area with air, which is conducive to improving the paint retention effect. On the contrary, if the double-layer rods 22 were made into one layer, it would be too dense and not conducive to the passage of air.

[0026] The outer diameter of the outer connecting ring 21 is larger than the inner diameter of the sleeve 11 and smaller than the inner diameter of the expansion section 12. The outer connecting ring 21 fits inside the expansion section 12. During operation, the paint thrown off by the oil slinger 2 falls onto the inner wall of the expansion section 12. The air flow speed at the expansion section 12 is slow, and the paint here does not easily cure, which facilitates the paint to automatically flow away from the lower front of the separation mechanism.

[0027] The rotating shaft 4 includes a first mating section 42 and a second mating section 44. A convex ring 43 is provided between the first mating section 42 and the second mating section 44. An inner connecting sleeve 23 is sleeved on the first mating section 42. A flat key is provided between the inner connecting sleeve 23 and the first mating section 42 to ensure that the oil slinger 2 rotates stably with the rotating shaft 4.

[0028] The sleeve 11 has a support sleeve 13 inside, and the second mating section 44 is rotatably fitted on the support sleeve 13. The rotating shaft 4 is rotatably connected to the outer shell 1 by means of the support sleeve 13. A limit nut 5 is threadedly connected to one side of the second mating section 44. The limit nut 5 and the convex ring 43 clamp the support sleeve 13. The limit nut 5 and the convex ring 43 prevent the rotating shaft 4 from moving axially. In addition, in order to improve the smoothness of the rotation of the rotating shaft 4, a bearing or bushing can be provided between the second mating section 44 and the support sleeve 13.

[0029] Several support rods 14 are fixedly connected to the side wall of the support sleeve 13 at equal angles, and the other end of the support rods 14 is fixedly connected to the inner wall of the sleeve 11. The support sleeve 13 is fixedly connected to the sleeve 11 by means of the support rods 14.

[0030] One end of the first mating section 42 is fixedly connected to a threaded section 41, and an end cap 3 is threadedly connected to the threaded section 41. The end cap 3 is tightened to press against the oil slinger 2, so that the end cap 3 is mated on the threaded section 41 and tightened, thereby pressing the oil slinger 2 to fix it and restricting the axial movement of the oil slinger 2 from falling off the rotating shaft 4.

[0031] One end of the second mating section 44 is fixedly connected to a coupling section 45, which is hollow. The side wall of the coupling section 45 is threaded with a fixing bolt 46. The output end of the external drive mechanism is inserted into the inside of the coupling section 45. Then, the fixing bolt 46 is tightened to fix the rotating shaft 4 and the drive mechanism together.

[0032] The side wall of the sleeve 11 is fixedly connected with several connecting ears 15, and the connecting ears 15 are provided with through holes. Bolts, nuts, etc. are used to pass through the through holes to fix the separation mechanism in the working area.

[0033] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
