The utility model relates to a cooling tower material temperature monitored control system, the cooling tower include the base, set up the discharge hopper on the base, the row who from bottom to top sets gradually on the discharge hopper expects drive mechanism, cooling bin, upper cover and bulk cargo ware, cooling bin and bulk cargo ware between still be equipped with flow control mechanism, material temperature monitored control system including the temperature sensor that sets up respectively in four inside corners of cooling bin, set up electric cabinet and alarm on the cooling bin outer wall, the electric cabinet pass through the circuit and be connected with temperature sensor, alarm electricity respectively, the electric cabinet on still be equipped with temperature -indicating element. Compared with the prior art, the utility model discloses simple structure, economical and practical, the material temperature that near each corner of was located to the cooling bin discharge gate can effectively be monitored to the safety and stability, can effectively solve and expect because of the corner that the temperature is widely different, causes partial material temperature higher, does not reach the technical problem that the cooling required the standard and resulted in finished product time machine.
