Abstract

The invention discloses a method and device for automatic layer exchange during irradiation of goods container. The method comprises the following steps of: conveying a spreader into or out of an irradiation room by a suspension conveyor system; and carrying out layer exchange on an upper-layer suspension box and a lower-layer suspension box on the spreader by a hydraulic lifter and a movable working platform. The device is arranged in a goods handling hall, and consists of the suspension conveyor system, the hydraulic lifter, the movable working platform, the upper-layer suspension box, the lower-layer suspension box and a positioning pin. The method and the device have high automation, save time and labor, are convenient to maintain, cab be used for quickly exchanging the upper-layer suspension box and the lower-layer suspension box to make the uniformity of irradiation absorption dose of goods meet requirements, and increases energy availability factor of a radioactive source and the quantity of irradiated goods.

Description

technical field [0001] The invention belongs to the field of irradiation processing, and in particular relates to a method and a device for automatically changing layers of irradiated cargo boxes. Background technique [0002] Radiation disinfection and sterilization processing is the process of processing substances or materials through physical, chemical or biological changes caused by the interaction of ionizing radiation (including nuclear radiation produced by radionuclides and particle beams produced by accelerators) with substances or materials. . Generally, radiation disinfection mainly refers to 60 Co radiation source or 137 The gamma-rays produced by Cs are processed by radiation, so that the object to be irradiated can achieve the purposes of killing insects, preventing mildew, disinfecting, and sterilizing, improving hygiene quality, food storage and preservation, and improving material properties. [0003] From the 1950s to the present, all the radiation proc...
