Description

Technical Field

[0001] The utility model relates to the technical field of flue flaps, in particular to an automatic control device for flue flaps. Background Art

[0002] A flue flap is a device used to control the flow and direction of gas in a flue. It usually consists of movable baffles or blades and can be adjusted by a manual or automatic control system. The main functions of a flue flap include flow control: by adjusting the position of the flap, the size of the flue opening can be changed, thereby controlling the gas flow through the flue. Pressure regulation: the opening and closing of the flap can affect the airflow resistance in the flue, thereby regulating the pressure in the system. Direction control: certain designs of flaps can also change the flow direction of the gas to adapt to different process requirements or environmental conditions. Safety function: in an emergency, the flap can be quickly closed to prevent fire or other dangerous substances from spreading through the flue. Flue flaps are widely used in various industrial fields, such as power generation, chemical industry, metallurgy, papermaking, etc., as well as in ventilation and air-conditioning systems in commercial and residential buildings.

[0003] Currently, the furnace worker pulls the flap chain to open the flap, and then manually hangs the counterweight on the chain after the flap is opened. The entire operation requires manual operation, and the flue flap area is a high-temperature dangerous area. Especially during the furnace operation, the process of pulling the flap chain requires proximity to high-temperature calcium carbide of 1000°C. This process poses a huge safety hazard. Secondly, when the furnace worker hangs the counterweight, because he wears thick gloves, the counterweight is easy to slip, and there is a risk of personal injury. Utility Model Content
