Device for controlling temperature of urea melting heat conducting oil of ureabased compound fertilizer

The invention discloses a device for controlling the temperature of urea melting heat conducting oil of ureabased compound fertilizer, comprising a urea melting slot as well as a stirring pump, a urine pump and a digital display temperature control instrument which are all arranged on the urea melting slot, wherein the urea melting slot is also connected with an electric adjusting valve and a heat-insulating oil furnace. The device for controlling the temperature of urea melting heat conducting oil of ureabased compound fertilizer has the following advantages that: by adopting the device, heat-insulating oil can be used as a heat resource to replace steam; meanwhile, the temperature of urine is controlled between 122 DEG C and 130 DEG C, the urine can be automatically returned to the heat-insulating oil furnace to be heated for reusing when the temperature of the heat-insulating oil is lower than 122 DEG C so as to save the energy resource and avoid the environment from adverse effects; in addition, the equip
