DETAILED DESCRIPTION
[0014] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0015] Embodiment: A novel inlet gas seal arrangement device, such as Figure 1 As shown, it includes a coating production line frame 1, on which an air sealing assembly is arranged. A plurality of air sealing assemblies are arranged along the length direction of the coating production line frame 1 to achieve an airtight effect between various work sections in the coating production line.
[0016] The air sealing assembly includes an air supply device 2 and an air induced device 3, wherein the air supply device 2 and the air induced device 3 are arranged opposite to each other in a vertical direction, that is, the air delivered by the air supply device 2 is guided by the air induced device 3, thereby achieving a stable air sealing effect and limiting the overflow of gas in the production line and the mixing of external gas.
[0017] The air supply device 2 includes an air curtain device 4 fixed to the coating production line frame 1 and an inlet air supply fan 5 connected to the air curtain device 4. A dark groove 17 for the air curtain device 4 to be embedded is provided at the bottom of the coating production line frame 1. A protective screen 18 is provided at the notch of the dark groove 17. The air curtain device 4 is connected to the inlet air supply fan 5 through an air supply duct 6. The provision of the protective screen 18 reduces the influence of impurities on the normal supply of the air curtain device 4. A plurality of air volume regulating valves are provided in the air curtain device 4, which can adjust the air volume according to the real-time working conditions and always adapt to the working conditions of the actual production line.
[0018] The air induction device 3 includes an air collecting hood 7 arranged above the air curtain device 4, an exhaust duct 8 connected to the air collecting hood 7, and an exhaust fan 9 arranged at the end of the exhaust duct 8. The exhaust fan 9 is also connected to a dust filter bag device 10. The air sent out from the air supply device 2 is partially drained and discharged through the air collecting hood 7. A telescopic guide tube 11 is connected between the air collecting hood 7 and the exhaust duct 8, which can meet different working conditions in the coating production line. The telescopic guide tube 11 is driven to achieve a fast and efficient airflow diversion response. In particular, when some stable and high-pressure gases are in the upper airflow, the air collecting hood 7 can flexibly and timely guide the flow. The port of the air collecting hood 7 is provided with an exhaust filter device 12, which reduces the mixing of impurities and further ensures the reliable exhaust gas treatment function of the subsequent dust filter bag device 10.
[0019] The side of the coating production line rack 1 is also provided with an auxiliary maintenance device, which includes a lifting vertical rail 13 and an inspection fence 14 movably connected to the lifting vertical rail 13, which is convenient for maintenance personnel to perform maintenance, especially timely emergency treatment when the device fails. At the same time, a movable heat dissipation port 15 is also provided at the bottom of one side of the coating production line rack 1. The movable heat dissipation port 15 is rotatably connected to a sealing protection sheet 16. Under normal working conditions, the sealing protection sheet 16 and the movable heat dissipation port 15 remain closed. Once the temperature inside the coating production line rack 1 is abnormal, the operator can manually open the sealing protection sheet 16 to achieve rapid cooling and diversion, so as to facilitate the maintenance operator to timely screen the internal working conditions.
[0020] Taking into account the stability of air flow and the excessively high temperature of some gases, the air supply duct 6 and the air exhaust duct 8 are both double-layer structures, which reduces the heat exchange process between the conveying air flow and the outside world and always maintains a reliable closed-loop air-sealed state.
[0021] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
