Abstract
Description
Technical Field
[0001] This invention relates to the field of paint collection technology, and more particularly to a collection device for atomized paint used in paint booths. 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 methods use water curtains to absorb paint from the air. Specifically, air in the spray booth passes through a water curtain, and the paint naturally dissolves into the water. Relatively speaking, the contact area between the water curtain and the air is limited, and the amount of paint dissolving into the water is also limited. Furthermore, the paint remaining in the air during subsequent exhaust gas treatment undoubtedly increases the difficulty of exhaust gas treatment. Summary of the Invention
[0004] To address the aforementioned problems, this invention discloses a collection device for atomized paint in a paint booth, comprising a housing with openings on both the front and back. An installation plate is fixedly connected inside the housing, and several separation mechanisms are fixedly connected to the installation plate. Each separation mechanism includes a drive motor and an oil-slinging disc fixed to the output end of the drive motor. In use, the collection device requires the assistance of a pre-installed air supply system in the paint booth to allow air from the booth to pass through it. Simultaneously, the drive motor operates, driving the oil-slinging disc to rotate. The atomized paint in the air passing through the disc is trapped and separated.
[0005] Two water pipes are installed on the upper part of the outer casing, located on both sides above the mounting plate. Several nozzles are fixedly connected to the water pipes. Water is pumped into the water pipes and delivered from the nozzles in a mist form, increasing the humidity inside the casing. This not only hinders the evaporation of solvents in the paint, but the water also acts as a solvent for the paint, greatly reducing the viscosity of the paint. This ensures that the paint does not harden and adhere to the inner wall of the casing, facilitating paint collection. The two water pipes serve the same purpose.
[0006] Preferably, a honeycomb panel is fixedly connected to the front opening of the outer casing, and a wire mesh is fixedly connected to the back opening of the outer casing. The honeycomb panel ensures uniform airflow into the outer casing and reduces water mist overflow, while the wire mesh further separates the paint. The water mist wets the paint passing through the oil-splattering pan, ensuring that the paint can drip down after adhering to the wire mesh.
[0007] Preferably, a support frame is provided at the bottom of the outer shell, and fixing plates are fixedly connected to the four corners of the upper end of the support frame. The outer shell is placed on the support frame, and the fixing plates fit around the four corners of the outer shell. The support frame has a cuboid structure and is welded from several square steel bars. The fixing plates are provided to prevent the outer shell from slipping off the support frame due to vibration or other factors.
[0008] Preferably, a manifold is fixedly connected to the lower end of the outer casing, and a drain pipe is fixedly connected to the lowest point of the manifold. Liquid flowing from the separation mechanism and liquid blocked by the wire mesh are both discharged through the manifold and the drain pipe.
[0009] Preferably, the upper end of the outer casing is covered and fixedly connected with a top cover plate. The top cover plate seals the upper end of the outer casing.
[0010] The beneficial effects of this invention are as follows:
[0011] 1. It is equipped with two water pipes that deliver atomized water from the nozzle to moisten the inside of the casing. This not only inhibits the evaporation of solvents in the paint, but also acts as a solvent, greatly reducing the viscosity of the paint and preventing it from adhering to and solidifying inside the casing.
[0012] 2. It is equipped with two separation stages, both of which use water mist spraying to wet the paint and reduce its viscosity. First, the paint is separated by the separation mechanism, and then it is trapped by the steel wire mesh. This can separate more than 95% of the paint in the air. Attached Figure Description

[0018] 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.
[0019] like Figures 1 to 3 As shown, a collection device for atomized paint in a paint booth includes a housing 3, which has a cuboid structure. Openings are provided on both the front and back of the housing 3 to allow airflow, i.e., air enters from the front and exits from the back. An installation plate 9 is fixedly connected inside the housing 3. The installation plate 9 is a single plate with pre-drilled mounting holes. Several separation mechanisms 8 are fixedly connected to the installation plate 9. Each separation mechanism 8 separates the oil mist from the air. Each separation mechanism 8 includes a drive motor and an oil-slinging disc fixed to the output end of the drive motor. It also includes a housing that holds the drive motor and the oil-slinging disc, which is fixedly connected to the installation plate 9. During operation, the drive motor is started, and the oil-slinging disc rotates. The atomized paint in the air passing through the oil-slinging disc is adhered and trapped, and then spun onto the housing as the disc rotates, achieving the effect of paint separation.
[0020] Furthermore, this device does not have a negative pressure or air supply mechanism. Since the device is used in a paint booth, it is installed at the exhaust system of the paint booth during operation. If it is a paint booth, an exhaust fan is added to the back of the device to ensure that the air can pass through the device and be processed.
[0021] Two water pipes 10 are provided on the upper part of the outer casing 3, and the water pipes 10 are located on both sides above the mounting plate 9. Several nozzles 11 are fixedly connected to the water pipes 10. Both water pipes 10 spray water mist to wet the paint, reduce its viscosity, and prevent the paint from adhering and hardening inside the outer casing.
[0022] A honeycomb panel 4 is fixedly connected to the front opening of the outer casing 3. The honeycomb panel 4 has regular hexagonal holes with a relatively large depth. This arrangement ensures that the air entering the device flows directly towards the separation mechanism 8, reducing water mist overflow from the front of the device. A wire mesh 12 is fixedly connected to the back opening of the outer casing 3. The water mist sprayed by the water pipe 10 located on the front of the separation mechanism 8 is intercepted by the separation mechanism 8, while the water mist sprayed by the water pipe 10 located on the back of the separation mechanism 8 is intercepted by the wire mesh 12. In actual operation, this device can separate more than 95% of the paint in the air, greatly reducing the burden on subsequent air purification equipment. In addition, the collected paint can be further processed and utilized, turning waste into treasure.
[0023] A support frame 1 is provided below the outer shell 3. The support frame 1 is a cuboid frame composed of several square steel bars. The outer shell 3 is placed on the upper end of the cuboid frame. If necessary, it is further fixed with bolts and nuts. Fixing plates 2 are fixedly connected to the four corners of the upper end of the support frame 1. The fixing plates 2 are L-shaped pieces in plan view. They are obtained by bending a plate at 90°. The outer shell 3 is placed on the support frame 1, and the fixing plates 2 hug the four corners of the outer shell 3. When the outer shell 3 is placed on the upper end of the support frame 1, the fixing plates 2 restrict the sliding of the outer shell 3.
[0024] The lower end of the outer casing 3 is fixedly connected to a manifold 6, and the intercepted water and paint fall into the manifold 6. The lowest point of the manifold 6 is fixedly connected to a drain pipe 7, which is connected to a treatment pipe to send the water and paint to the treatment equipment.
[0025] The upper end of the outer casing 3 is covered and fixedly connected with an upper cover plate 5. The upper cover plate 5 is a plate that seals the upper end of the outer casing 3. It should be noted that there are also related plates inside the outer casing 3 to prevent air from reaching the wire mesh 12 set on the back without passing through the separation mechanism 8.
[0026] 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.
