This invention discloses a mobile aluminum ladle baking device, relating to the field of metallurgical equipment technology. It includes a base frame, with a lifting unit and several support frames fixedly mounted on the upper end of the base frame. An installation unit is located on the front side of the lifting unit, and an igniter unit is fixedly connected to the bottom front side of the installation unit. A gas delivery unit is located on the upper part of the support frames, a gas control unit is located on the upper right side of the installation unit, and an air supply unit is located on the upper left side of the installation unit. This invention, through the base frame, electric forklift, traveling unit, and support units, achieves flexible movement, rapid positioning, and stable support of the device within the work area; the lifting unit enables precise lifting of the installation unit, igniter unit, gas control unit, and air supply unit; and the gas delivery unit, gas control unit, air supply unit, and igniter unit ensure safe gas delivery and precise gas-air mixing.

This invention relates to the field of cross-flow fan technology, and more particularly to a cross-flow fan blade and a cross-flow impeller using the same, comprising a blade body; the blade body is a solid structure, and the outer surface of the blade body includes a pressure surface, a suction surface, and two side surfaces; the two ends of the pressure surface respectively enclose the two ends of the suction surface to form a leading edge and a trailing edge of the blade, both of which have rounded ends; the pressure surface gradually concaves towards the suction surface from one end of the leading edge to one end of the trailing edge, and the size of the leading edge is larger than that of the trailing edge; the cross-sectional thickness of the blade body gradually decreases from one end of the leading edge to one end of the trailing edge; the suction surface has a recessed cut that does not penetrate the pressure surface but penetrates both side surfaces. This invention can solve the problems of severe airflow separation, large inlet air impact, high vortex noise, and low fan efficiency existing in the prior art of cross-flow fan blades.

This utility model relates to the field of environmental protection equipment technology, specifically an environmentally friendly paint spray booth with efficient paint mist treatment and exhaust gas purification functions. It includes a booth body, with an air supply system and an exhaust system installed on the outside of the body. The booth body treats exhaust gas through an environmental protection treatment unit, which includes a high-efficiency paint mist capture system located inside the booth body and an activated carbon adsorption exhaust gas purification system installed on the outside of the booth body. In this environmentally friendly paint spray booth with efficient paint mist treatment and exhaust gas purification functions, a high-efficiency paint mist capture system is installed inside the booth body. A circulating water tank, a water pump, and a water curtain plate work together to form a stable water curtain, directly intercepting and capturing paint mist through collision. Combined with the paint mist capture chamber and exhaust fan, the system utilizes water flow scouring and turbulent condensation to efficiently remove paint mist, including fine particles. Compared to traditional filtration methods, the paint mist capture efficiency is improved, reducing the harm of paint mist to the environment and operators, and lowering the cost and replacement frequency of filter consumables.
