Description

Technical Field

[0001] This utility model relates to water curtain technology, specifically a water curtain mechanism for polishing and spraying a paint booth. Background Technology

[0002] A spray booth, also known as a paint spraying room, is a coating equipment specifically designed for spraying liquid paint. It is an essential and critical facility in a painting workshop. The water curtain mechanism in the spray booth can directly spray the paint mist remaining during spraying onto the water curtain surface. The water curtain mechanism uses high-speed airflow to quickly absorb dust, bacteria, and other particles in the air and then discharge them, keeping the indoor air fresh.

[0003] Existing water curtain systems typically distribute circulating water evenly on the surface of a water curtain panel located above a water storage tank, enabling it to effectively collect paint mist. However, paint mist will still remain in the air, resulting in poor cleaning performance and pollution of the external environment if discharged directly. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a water curtain mechanism for polishing a spray booth, which can effectively remove paint mist from the air inside the spray booth.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a water curtain mechanism for a sanding and painting booth, comprising a water storage tank, an air intake cabinet and an exhaust cabinet above the water storage tank, a water curtain plate on the air intake cabinet, an overflow pool on the top of the water curtain plate, a first water inlet in the overflow pool, an overflow plate on the side of the overflow pool facing the water curtain plate, water in the overflow pool overflowing evenly from the overflow plate to the water curtain plate, a water curtain pool between the air intake cabinet and the exhaust cabinet, a water curtain plate at the bottom of the water curtain pool, a second water inlet in the water curtain pool, and through holes evenly opened on the water curtain plate, water in the overflow pool falling from the through holes to form a water curtain.

[0006] Preferably, a flow stabilizing plate is provided on the top of the overflow tank, the flow stabilizing plate is located between the overflow plate and the first water inlet, and the bottom of the flow stabilizing plate is lower than the top of the overflow plate.

[0007] Preferably, the bottom of the water storage tank is connected to the settling tank, and the top of the settling tank is covered with a cover plate.

[0008] Preferably, the settling tank is connected to a circulation pump, which is used to pump water from the settling tank to the first inlet and the second inlet.

[0009] Preferably, the exhaust cabinet is provided with several baffles, each baffle having an exhaust port, and each exhaust port having a filter screen.

[0010] Preferably, the top of the exhaust cabinet is provided with filter cotton, which is located above the baffle.

[0011] Preferably, the exhaust cabinet is provided with an inspection port, and the inspection port is provided with an inspection plate.

[0012] In summary, this utility model achieves the following technical effects:

[0013] The water curtain mechanism of this utility model for the sanding and spraying booth uses water curtain plates to form a water curtain and water curtain panels to form a multi-layer water curtain structure, thereby effectively adsorbing paint mist in the air inside the spraying booth. In addition, with the baffle and filter cotton in the exhaust cabinet, the residual paint mist and water vapor in the air are filtered, further improving the cleaning effect.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] Example 1:

[0023] like Figure 1 As shown, a water curtain mechanism for a sanding and spraying booth includes a water storage tank 3. An air intake cabinet 1 and an exhaust cabinet 5 are provided above the water storage tank 3. The air intake cabinet 1 is provided with a water curtain plate 13. An overflow pool 2 is provided at the top of the water curtain plate 13. A first water inlet 8 is provided in the overflow pool 2. An overflow plate 10 is provided on the side of the overflow pool 2 facing the water curtain plate 13. Water in the overflow pool 2 overflows evenly from the overflow plate 10 to the water curtain plate 13. A water curtain pool 4 is provided between the air intake cabinet 1 and the exhaust cabinet 5. A water curtain plate 12 is provided at the bottom of the water curtain pool 4. A second water inlet 11 is provided in the water curtain pool 4. The water curtain plate 12 is evenly provided with through holes. Water in the overflow pool 2 falls from the through holes to form a water curtain.

[0024] During spraying, most of the excess paint mist is sprayed onto the water curtain plate 13, carried away by the water curtain and stored in the water storage tank 3. The air containing paint mist flows from the air intake cabinet 1 to the exhaust cabinet 5. When passing under the water curtain pool 4, most of the paint mist in the air is removed by the multi-layer water curtain structure formed by the water curtain plate 12. The remaining small part of paint mist is blocked by the baffle 15 and filtered by the filter cotton 16 to ensure clean air emission.

[0025] The water curtain mechanism of the sanding and spraying chamber in this embodiment uses a water curtain plate 13 to form a water curtain and a water curtain plate 12 to form a water curtain, forming a multi-layer water curtain structure, thereby effectively adsorbing paint mist in the air of the spraying chamber. In addition, with the baffle 15 and filter cotton 16 in the exhaust cabinet 5, the residual paint mist and water vapor in the air are filtered, further improving the cleaning effect.

[0026] The top of the overflow pool 2 is provided with a flow stabilizing plate 9, which is located between the overflow plate 10 and the first water inlet 8. The bottom of the flow stabilizing plate 9 is lower than the top of the overflow plate 10. The flow stabilizing plate 9 can stabilize the water surface between the flow stabilizing plate 9 and the overflow plate 10, ensuring that the water in the overflow pool 2 overflows evenly from the overflow plate 10 to the water curtain plate 13, forming a stable water curtain surface on the water curtain plate 13.

[0027] The bottom of the water storage tank 3 is connected to the settling tank 6, and the top of the settling tank 6 is covered with a cover plate; the setting of the settling tank 6 allows the circulating water to settle, thus separating the paint and water.

[0028] The settling tank 6 is connected to a circulation pump 7, which is used to pump water in the settling tank 6 to the first inlet 8 and the second inlet 11.

[0029] The exhaust cabinet 5 is provided with several baffles 15, each baffle 15 having an exhaust port and a filter screen. The baffles 15 can block the airflow, causing the airflow velocity to drop rapidly upon impact, so that paint mist and water mist can achieve gas-liquid separation due to inertia impacting the baffles 15.

[0030] The exhaust cabinet 5 is equipped with a filter cotton 16 on its top, which is located above the baffle 15; the filter cotton 16 can filter out the remaining paint mist and water mist in the air.

[0031] The exhaust cabinet 5 is provided with an inspection port 14, and the inspection port 14 is provided with an inspection plate.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
