Overload protection device suitable for combustor of drying equipment

The invention discloses a drying equipment burner overload protection device which comprises a drying equipment body, the drying equipment body comprises a grain storage section, a fan side air duct and a burner side air duct are arranged on the two sides of the grain storage section, and a burner is installed in the burner side air duct and used for heating air in the air ducts; a flame temperature monitoring sensor is installed above the combustor and connected with an overload switch, and the overload switch is connected with a PLC. The invention has the advantages that the flame temperature monitoring sensor is arranged at the upper part of the built-in burner of the drying equipment to monitor and display the flame temperature of the burner, and when the flame temperature exceeds the set temperature (such as 115 DEG C), the overload switch is triggered, the PLC sends an instruction to close the gas supply electromagnetic valve and the air induction electromagnetic valve of the burner, and the purpose of
