According to news from August 23, 2025, **information from the Intellectual Property Office shows that Hubei Huawei Petrochemical Machinery Equipment Manufacturing Co., Ltd. has obtained a patent titled “A spraying device for processing pressure vessel tanks,” with the approval announcement number CN223249617U; the application was filed in August 2024. The patent abstract indicates that this utility model relates to a spraying device for processing pressure vessel tanks. It includes a workbench, with transmission components located at both the top and bottom of the workbench. These transmission components consist of a frame that is fixedly attached to the outer surface of the workbench; a connection seat is fixedly attached to the front side of the frame, and a linear actuator is fixedly attached to the front side of the connection seat. An installation plate is then fixedly attached to the output end of the linear actuator. This spraying device, used for processing pressure vessel tanks, places the opening of the tank on a stabilizing base, and can be applied to tanks of different diameters. The linear actuator drives the spraying tank body up and down, thereby applying paint to the tank from above and below. By activating the second motor, the fixed column, stabilizing base, and the tank itself rotate, allowing for comprehensive painting of the tank. Once painting is complete, the first motor is activated to rotate the connecting plate, thus moving the tank on the other end of the stabilizing base to the top of the collection box, enabling continuous processing of the tank.
