Problems solved by technology

[0002] At present, the existing temperature adjustment mechanism of the hot blast stove adopts the method of distributing cold air to control the outlet air temperature of the hot blast stove. This method of distributing cold air has poor temperature control accuracy, large temperature fluctuations, large heat loss, and low efficiency; especially When the heat exchange exhaust fan is shut down, the high-heat flue gas in the heat exchanger cannot fully exchange heat, which will cause dry burning of the heat exchanger of the hot blast stove, and the temperature of the heat exchanger will be overheated, causing deformation of the heat exchange device, thereby reducing the use life

Abstract

The invention relates to a temperature regulating mechanism of a hot blast stove, in particular, it is installed on the air outlet pipe of the hot blast stove, and can automatically control the temperature of the hot blast of the heat source. It is mainly installed on the base with a cover plate; two valve bases are installed on the base, and the two valve plates are respectively installed on the valve guide groove; the bearing seat fixes two execution screw rods and position transmission screw rods on the base respectively; The driven sprocket and the main drive sprocket are respectively installed on the two execution screw rods, the position driven sprocket is installed on the position drive screw rod; the reduction motor is installed on the motor mounting plate. The invention can automatically bypass the high-temperature flue gas in the combustion chamber of the hot blast stove through the temperature adjustment mechanism to prevent dry burning of the heat exchanger; it can control the amount of heat exchange, automatically control the temperature of the hot air, and make the air volume and wind speed of the heat exchange air channel Parameters such as wind pressure and wind pressure are not subject to any change; the life of the heat exchange device of the hot blast stove will not be affected, and it will not be deformed due to excessive temperature.
