Description

Technical Field

[0001] This utility model relates to metal hoods for emitting exhaust mist in construction projects, and more particularly to a metal hood for emitting exhaust mist from the extruder of a film production line. Background Technology

[0002] In film production lines, extruders emit waste gas mist during operation. If left untreated, this mist can pollute the working environment, harm the health of operators, and potentially damage surrounding equipment. Traditional treatment methods may be inefficient and ineffective. However, specially designed metal hoods for absorbing the waste gas mist emitted by extruders in film production lines can effectively solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a metal hood for discharging exhaust mist from the extruder of a film production line. Its structure is reasonable, and it can centrally collect and treat the exhaust mist, improve the quality of the production environment, ensure the smooth operation of production, and reduce the adverse effects of exhaust mist on workers.

[0004] The purpose of this utility model is achieved as follows: A metal cover for discharging exhaust gas mist from an extruder in a film production line. A rectangular stainless steel base plate with a central opening has two symmetrical inclined plates on either side, each tilted inward at 45°. Air vents are evenly distributed on the inclined plates. A protective cover is fixed to the top of the two inclined plates to form a trapezoidal metal cover. The protective cover has a structure in which downward-facing, symmetrical short plates are arranged along the two long sides of the rectangular protective plate, and these short plates are fixed to the inclined plates. T-shaped baffles are arranged on both sides of the trapezoidal metal cover. An upward-curving pipe is installed on the air vent, connecting to an upward-facing air outlet pipe. The size of the central opening of the trapezoidal metal cover is adapted to the size of the extruder in the film production line.

[0005] This utility model can be installed above an extruder to collect and discharge the exhaust gas mist generated by the extruder, achieving a highly efficient and environmentally friendly function.

[0006] This invention features a specific shape and structure, better suited to the working characteristics of extruders, enabling centralized collection and treatment of exhaust mist. Through its rational design, it achieves highly efficient exhaust mist absorption, improving the quality of the production environment and ensuring smooth production operations. Furthermore, the choice of metal materials provides it with durability and stability, allowing for prolonged use in harsh production environments. Attached Figure Description
