[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the embodiments, by Figure 1-4 The present invention discloses an air supply device for a paint booth. The present invention includes a blower 1, two filter frames 2 are slidably connected inside the air inlet pipe of the blower 1, filters 3 are fixedly connected inside the two filter frames 2 by fasteners, baffles 4 are fixedly connected to the outside of the two filter frames 2, and the two baffles 4 are fixedly connected to the air inlet pipe of the blower 1 by fasteners. An air supply duct 5 is fixedly connected to the outside of the air outlet of the blower 1 by fasteners. A guide plate 6 is fixedly connected inside the air supply duct 5. A flow equalization plate 7 is fixedly connected inside the air supply duct 5. An air outlet frame 8 is fixedly connected to the outside of the air supply duct 5 by fasteners. A louvered air outlet nozzle 9 is provided inside the air outlet frame 8.

[0028] The baffle 4 is fixedly connected to the outside of the baffle 10, and a sealing gasket is provided inside the baffle 4. The baffle 4 is connected to the air inlet pipe of the blower 1 by bolts.

[0029] In this embodiment, during actual use, the filter 3 inside the filter frame 2 can filter the airflow passing through the blower 1. The baffle 4 can easily fix the two filter frames 2 stably inside the air inlet pipe of the blower 1. The handle 10 can easily lift and remove the filter frame 2 when disassembling the filter 3. The sealing gasket ensures the airtightness inside, so that the air inlet pipe of the blower 1 maintains stable air intake.

[0030] The blower 1 has a sliding groove inside its air inlet pipe, and the two filter frames 2 are fixedly connected to sliders 11 that slide in the sliding groove on both the left and right sides.

[0031] In this embodiment, during actual use, when the filter frame 2 is placed inside the air inlet pipe of the blower 1, the slider 11 on the outside of the filter frame 2 will slide along the direction of the slide groove. The slide groove prevents the filter frame 2 from shaking and provides it with more stable support.

[0032] The guide plate 6 is arranged in a sloping shape and is located at the inlet of the air supply duct 5.

[0033] In this embodiment, during actual use, the sloping guide plate 6 is designed according to the principles of fluid mechanics, which can guide the airflow to be evenly distributed in the duct, reduce eddies and wind resistance, and make the airflow flow more smoothly. The guide plate 6 should be tightly attached to the inner wall of the duct to ensure that the airflow can flow smoothly into the air supply pipe 5.

[0034] The flow equalization orifice plate 7 has a number of ventilation holes inside, and the flow equalization orifice plate 7 is located at the outlet of the air supply duct 5.

[0035] In this embodiment, during actual use, the flow equalization plate 7 has multiple small holes evenly distributed on it, which can further equalize the airflow and make the air delivered from the air outlet evenly cover all areas in the paint booth, ensuring that the paint surface dries evenly.

[0036] The air outlet frame 8 is connected to the air supply duct 5 by bolts. The air outlet frame 8 is arranged in a ring shape, and a lever is provided on the outside of the louvered air outlet 9.

[0037] In this embodiment, the air outlet frame 8 is easy to disassemble and install during actual use. According to the requirements of different car models and painting processes, the operator can flexibly adjust the direction and air volume of the louvered air outlet 9 to ensure uniform airflow distribution in the paint booth and meet the needs of high-quality painting.

[0038] Working principle:

[0039] This device is used to supply air to the paint booth. The blower 1 is a high-efficiency centrifugal fan with a dynamically balanced impeller, providing a stable airflow and high air supply efficiency to meet the air supply needs of the paint booth under different operating conditions. The fan motor is an energy-saving motor to reduce operating costs. The two filters 3 are a pre-filter and a medium-efficiency filter bag, respectively. The pre-filter mainly filters large particulate impurities in the air, such as dust and paint residue, protecting the subsequent filter components and the blower 1. The medium-efficiency filter bag further filters fine particles, ensuring the air supplied to the paint booth is of high quality. To ensure cleanliness and prevent impurities from contaminating the paint surface and affecting its quality, the filter assembly adopts a drawer-type structure, facilitating regular replacement and cleaning of the filter material. The air supply duct 5 features a modular design, connecting to the blower 1 via bolts or flanges. It can be flexibly assembled and installed according to the size and shape of the paint booth, facilitating construction and subsequent maintenance. The louvered air outlet 9 is an adjustable air outlet, allowing for precise control of the air supply direction and volume according to the actual needs of the paint baking operation by adjusting the angle and opening of the air outlet. This enables targeted air supply to different areas within the paint booth, improving the flexibility and adaptability of the air supply.
