Description

Technical Field

[0001] This utility model relates to the field of ventilation system technology, and in particular to a ventilation system for spraying equipment. Background Technology

[0002] In brake disc spraying equipment, the ventilation system is a crucial component for ensuring spraying quality and a safe working environment. Traditional spraying equipment ventilation systems often suffer from the following problems: First, the supply air temperature is unstable and easily affected by the ambient temperature, leading to uneven drying of the paint film during spraying, affecting the product's appearance and quality. Second, the supply air cleanliness is insufficient; the air may contain dust, impurities, and other contaminants, which can adhere to the wet paint surface, causing spraying defects. Furthermore, uneven airflow distribution can easily create dead zones or eddies in the spray booth and paint supply room, causing paint mist retention, increasing cleaning difficulty and safety hazards. In existing technologies, some ventilation systems lack effective temperature control and air filtration mechanisms, failing to meet the stringent air quality requirements of high-precision spraying processes.

[0003] In summary, a ventilation system for spraying equipment is needed to address the shortcomings of existing technologies. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a ventilation system for spraying equipment, aiming to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ventilation system for spraying equipment, comprising a body, a paint supply room, a spray booth, and a constant temperature air supply unit. The paint supply room, spray booth, and constant temperature air supply unit are all located on the body. The top of the paint supply room has a first air inlet for connecting to the constant temperature air supply unit, and the top of the spray booth has a second air inlet for connecting to the constant temperature air supply unit. The constant temperature air supply unit is used to continuously provide clean, constant temperature, and stable process air to the paint supply room and the spray booth. The constant temperature air supply unit includes a filter chamber, a heating chamber, and a pressure equalization chamber. The filter chamber is used to draw in outside air and pressurize it into the heating chamber. The heating chamber is used to heat the air from the filter chamber to the process set temperature. The pressure equalization chamber is used to stabilize and equalize the flow of the hot air from the heating chamber and evenly deliver it into the paint supply room and the spray booth. By integrating a constant-temperature air supply unit into the machine body and supplying air to the paint supply room and spray booth through the air inlet at the top, the core function of continuously providing clean, constant-temperature, and stable process air to the two key areas is achieved. This integrated structure effectively ensures the stability of the spraying environment parameters, thereby ensuring the uniformity of paint film quality and improving the overall quality of the sprayed products.

[0006] Furthermore, the filter chamber is equipped with a side plate filter, a fan, and a hose connector. The side plate filter is installed on the side wall of the filter chamber away from the heating chamber, and the air outlet of the fan is connected to the heating chamber through the hose connector.

[0007] Furthermore, the heating chamber is equipped with a first air duct, a hot air box, a second air duct, and a bend. One end of the first air duct is connected to a hose connector, and the other end of the first air duct is connected to the hot air box. The output end of the hot air box is connected to the bend through the second air duct, and the end of the bend away from the second air duct is connected to the pressure equalization chamber.

[0008] Furthermore, a number of bottom plate filters for flow equalization filtration are installed at the bottom of the equalization chamber, and the bottom plate filters are located directly above the first air inlet and the second air inlet.

[0009] Furthermore, the top of the machine body is equipped with an exhaust system and an air tank. The exhaust system is used to filter and discharge the exhaust gas from the machine body, and the air tank is used to provide stable and clean compressed air to ensure the quality of the power source for the paint spraying room.

[0010] Furthermore, an exhaust port for connecting to the ventilation mechanism is provided in the middle of the top wall of the machine body.

[0011] The beneficial effects of this utility model are:

[0012] 1. In this utility model, by setting up a constant temperature air supply unit, clean, constant temperature and stable process air can be continuously provided to the paint supply room and the spraying room, effectively avoiding the influence of temperature fluctuations on the spraying process and improving the uniformity and adhesion of the paint film.

[0013] 2. In this utility model, the combination of side plate filters and fans in the ground filtration chamber efficiently removes particulate matter and impurities from the outside air, ensuring the cleanliness of the supplied air and reducing spraying defects. The heating chamber, through the design of a hot air box and air duct, quickly heats the air to the process set temperature and maintains a stable temperature to meet the needs of different spraying environments. Multiple bottom plate filters are installed at the bottom of the pressure equalization chamber to achieve pressure stabilization and uniform flow of hot air, ensuring that the airflow is evenly distributed in the paint supply room and spraying room, avoiding excessively strong or weak local airflow, and improving spraying consistency and efficiency. The overall system has a compact structure, reasonable layout, and is easy to install and maintain, possessing certain practical and promotional value. Attached Figure Description
