The invention provides a method and equipment for calculating the irradiation heat generation rate of a fuel rod air cavity spring and a storage medium, and relates to the technical field of nuclear reactors. The method comprises the steps that S1, the energy deposition rate of gamma rays in the air cavity spring at the first temperature is obtained; s2, calculating the irradiation heating rate of the air cavity spring based on the energy deposition rate, the average heat flux density of the fuel rod and the heat release share of the reactor core; s3, calculating a second temperature of the air cavity spring based on the irradiation heat generation rate; s4, judging whether the second temperature meets a preset condition or not; s5, if yes, taking the irradiation heat generation rate as a calculation result; if not, executing the step S6; and S6, taking the second temperature as a new first temperature, and repeating the steps S1 to S5. According to the method, the radiation heating rate of the fuel rod air cavity spring is calculated, and the fuel rod performance analysis and design period is shortened.

The utility model relates to a mixing device for feed production, which comprises a base, an adding mechanism arranged at the top of the base and a mixing mechanism arranged at the top of the base, the adding mechanism comprises a side plate fixedly connected to the top of the base, one end of the side plate is hinged with a first electric push rod, and one end of the first electric push rod is hinged with a first storage barrel. The first storage barrel is hinged to the base, and one end of the first storage barrel is fixedly connected with a first adding hopper. The mixing device for feed production is provided with a structure convenient for adding additives, a traditional tedious mode of manually adding the additives by means of additional tools is abandoned, workers do not need to spend a lot of time and energy to carry out complex adding operation, and the additives can be added only through a specific adding channel or connector of the device. The additive can be easily added into the feed only by adding the additive into the feed, so that the adding time of the additive is greatly shortened, the efficiency of the whole feed production process is improved, and particularly in large-scale feed production, the yield can be remarkably increased, and the market demand is met.
