Description

Technical Field

[0001] This utility model belongs to the technical field of paint spraying exhaust gas treatment equipment, and specifically relates to a water bath hybrid paint spraying cabinet. Background Technology

[0002] Spray painting is a coating process in which paint is atomized and applied to the surface of an object using a spray gun to achieve decoration and protection. Spray painting is widely used in automobiles, furniture, construction, electronic equipment and other fields. In the industrial production process, the dust and exhaust gas generated by spray painting usually need to be adsorbed by exhaust gas treatment equipment to protect the environment and the health of operators. Among them, water bath hybrid spray painting booth is currently the core equipment for industrial spray painting exhaust gas treatment.

[0003] Chinese Patent No. CN222817132U discloses a water curtain cyclone spray booth, including a cabinet body and a water curtain mechanism, a cyclone mechanism, and a water circulation mechanism respectively installed on the cabinet body. The cabinet body has a parallel suction chamber and a processing chamber. The water curtain mechanism includes a water curtain plate and a water tank set on its top. The water curtain plate is set on the side of the suction chamber near the processing chamber. The cyclone mechanism includes a cyclone cylinder and a louvered fan. The cyclone cylinder is set in the processing chamber, and the louvered fan is rotatably set inside the cyclone cylinder. The water circulation mechanism includes a water tank, a water pump, a first guide plate, and a water curtain rear plate. The water tank is set at the bottom of the cabinet body. The water pump delivers water from the water tank to the water tank and the cyclone cylinder. One end of the first guide plate protrudes above the water surface of the water tank, and the other end gradually slopes downward toward the suction chamber. One end of the water curtain rear plate is connected to the water curtain plate, and the other end extends toward the processing chamber. The water curtain rear plate covers the first guide plate. The water curtain rear plate and the first guide plate form a channel connecting the suction chamber and the cyclone cylinder.

[0004] The above technical solution has the following defects: In this water curtain cyclone spray booth, water sprayed from the first nozzle enters the cyclone cylinder from top to bottom. Paint mist enters the cyclone cylinder from the bottom in a swirling state and rises in a swirling motion under the action of the louvered fan. Gas and liquid collide with each other in the cyclone cylinder, forming a mixture of gaseous, liquid and solid states. Some paint mist particles are separated by the centrifugal force of the swirling flow and are pushed to the cylinder wall. Some paint mist particles are captured by the circulating water in the cyclone cylinder. The circulating water and the separated and captured paint mist particles in the cyclone cylinder flow back to the water tank from the bottom of the cyclone cylinder. However, since there is only a single louvered fan in the cyclone cylinder, the single louvered fan cannot form a multi-dimensional swirling flow, resulting in uneven airflow distribution in the cyclone cylinder and insufficient swirling intensity in some areas. Some paint mist particles are not fully separated and escape with the airflow, so the paint mist removal effect is not good. Utility Model Content

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example

[0020] Water-bath hybrid spray booth, such as Figures 1 to 4 As shown, the device includes a cabinet 1 and a water curtain plate 2. The bottom of the cabinet 1 is provided with a water storage tank 3 for storing water. The water curtain plate 2 is installed on the cabinet 1 and is located directly above the water storage tank 3.

[0021] An overflow tank 9 is installed at the upper end of the water curtain plate 2, and a filter tank 10 is provided on the cabinet 1. A filter plate 11 for filtering water is installed in the filter tank 10. The filter tank 10 is connected to the water storage tank 3. The water filtered by the filter plate 11 in the filter tank 10 is pumped to the overflow tank 9 by the water pump 12 to prevent impurities from entering the water pump 12 and thus damaging the water pump 12.

[0022] Water in the storage tank 3 flows into the filter tank 10, and then impurities in the water are trapped by the filtering effect of the filter plate 11. The filtered water is pumped to the overflow tank 9 by the water pump 12. The water overflows from the overflow tank 9 and flows down through the water curtain plate 2. The water flows down to form a water curtain and flows back into the storage tank 3.

[0023] Furthermore, the front of the water curtain plate 2 is arc-shaped, with the arc-shaped arch facing forward. The lower end of the water curtain plate 2 is serrated. The arc-shaped structure allows the water to flow down close to the surface of the water curtain plate 2, preventing the formed water curtain from detaching, scattering, or generating turbulence due to the impact of airflow. Moreover, since the lower end of the water curtain plate 2 is serrated, it ensures that the water flow can leave the water curtain plate 2 in the form of multiple vertical and evenly distributed water lines, ensuring the integrity and uniformity of the formed water curtain.

[0024] The lower end of the water curtain plate 2 extends into the water storage tank 3. In this embodiment, the lower end of the water curtain plate 2 extends into the water storage tank 3 to a depth of 5cm, and there is a gap between the lower end of the water curtain plate 2 and the liquid surface of the water storage tank 3. It should be noted that during dynamic operation, the liquid surface of the water storage tank 3 will fluctuate. The lower end of the water curtain plate 2 extends into the water storage tank 3 to a depth of 5cm to ensure that the optimal gap between the lower end of the water curtain plate 2 and the liquid surface of the water storage tank 3 is maintained during dynamic operation.

[0025] Both sides of the filter tank 10 are provided with slots 14. The two sides of the filter plate 11 are respectively inserted into the corresponding slots 14. The filter plate 11 and the slots 14 are compatible. The slots 14 restrict the filter plate 11, thereby ensuring the stability of the filter plate 11 in the filter tank 10. When installing the filter plate 11, simply insert the two sides of the filter plate 11 into the corresponding slots 14. When removing the filter plate 11, the filter plate 11 can be directly removed to detach it from the slots 14. The operation is simple, the disassembly and assembly are convenient, and it is easy to clean and replace later.

[0026] The bottom of the filter tank 10 is sloped from high to low from one side to the other. A drain outlet 16 is provided on one side of the filter tank 10. The lowest point of the drain outlet 16 is flush with the lowest point of the bottom of the filter tank 10. A plug 15 is inserted into the drain outlet 16. When cleaning the filter tank 10, the plug 15 is removed by external force. Due to the inclined structure at the bottom of the filter tank 10, the water and impurities in the filter tank 10 flow to the drain outlet 16 under the guidance of the inclined structure and are discharged outward from the drain outlet 16, which facilitates the user's cleaning of the filter tank 10.

[0027] At least one cyclone cylinder 5 is provided on the cabinet body 1. At least two impellers 6 are provided inside the cyclone cylinder 5. The two impellers 6 are coaxially arranged inside the cyclone cylinder 5 and are spaced apart along the axial direction of the cyclone cylinder 5. In this embodiment, there are three cyclone cylinders 5, and each of the three cyclone cylinders 5 has two spaced impellers 6 coaxially arranged inside.

[0028] Two impellers 6 work simultaneously to form a multi-dimensional vortex within the cyclone cylinder 5, thereby enhancing the centrifugal force generated by the vortex. This causes more water and paint mist particles to be thrown onto the cylinder wall of the cyclone cylinder 5 under the action of centrifugal force, avoiding the problem of insufficient vortex intensity in local areas and reducing the amount of paint mist particles not being fully separated. A guide plate 4 is installed inside the water storage tank 3. The guide plate 4 includes a horizontal part 41, a protrusion 42, and a horizontal part 43. The horizontal part 41 and the horizontal part 43 are both located below the liquid surface of the water storage tank 3, while the protrusion 42 extends above the liquid surface of the water storage tank 3. The guide plate 4 can guide the flow of gas and water, and the protrusion 42 can prevent the backflow of paint floating on the liquid surface.

[0029] The first horizontal section 41 is located directly below the water curtain plate 2. The distance between the lower end of the water curtain plate 2 and the upper surface of the first horizontal section 41 is 10cm. The second horizontal section 43 is located directly below the cyclone cylinder 5. A through hole 7 is provided on the second horizontal section 43. The protrusion 42 is located between the first horizontal section 41 and the second horizontal section 43. The protrusion 42 is in the shape of an inverted "V".

[0030] A water curtain back plate 8 is provided on the rear side of the water curtain plate 2. The water curtain back plate 8 is inclined and extends from the water curtain plate 2 from high to low to directly below the cyclone cylinder 5. The end of the water curtain back plate 8 is serrated. The paint mist that enters the cyclone cylinder 5 through the water curtain is thrown onto the cylinder wall of the cyclone cylinder 5 by the centrifugal force generated by the cyclone. Then, under the action of gravity, it falls onto the water curtain back plate 8 and slides along the water curtain back plate 8 until it falls into the water storage tank 3.

[0031] The cabinet 1 has a mounting hole 13 for installing the fan, and the mounting hole 13 is located above the cyclone cylinder 5. Example

[0032] The difference between Example 2 and Example 1 is that, as Figure 5 As shown, the cabinet 1 is equipped with a spray pipe 18 and a water curtain inclined plate 17. The spray pipe 18 is located above the water curtain back plate 8, and the water curtain back plate 8 is located above the water curtain inclined plate 17. The water filtered by the filter plate 11 in the filter tank 10 is pumped to the spray pipe 18 by the water pump 12. The water is sprayed out through the spray pipe 18 and slides down the water curtain back plate 8 to form a water curtain and falls onto the water curtain inclined plate 17. It then slides down the water curtain inclined plate 17 to form a water curtain and falls into the water storage tank 3. The paint mist flows to the cyclone cylinder 5 through the two water curtains and is further treated by the two water curtains to enhance the paint mist removal effect.

[0033] It should be noted that the water filtered by the filter plate 11 in the filter tank 10 is pumped to the spray pipe 18 and the overflow tank 9 by the water pump 12. That is, the water pump 12 sends the water to the corresponding pipe, and then the water is distributed to the spray pipe 18 and the overflow tank 9 through the corresponding pipe.

[0034] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
