Electron accelerator under-beam device for powder material irradiation

Abstract

The invention discloses an electron accelerator under-beam device for powder material irradiation, and relates to an electron accelerator irradiation technology. The device is characterized by comprising an irradiation unit, a conveying unit, a power unit and a supporting unit, the irradiation unit is in a multi-edge hollow cylinder shape, the cylindrical outer surface is completely coated with a titanium film, the conveying unit comprises a powder connecting cylinder and a rotating copper sleeve, the power unit comprises a speed reducer and an overrun clutch to drive a driving shaft to rotate, and power chain wheels and chains are arranged at the two ends of the driving shaft respectively and used for driving the irradiation unit to rotate; and the device has the beneficial effects that wind power for blowing powder is used for air cooling, and the under-beam irradiation unit keeps rotating, so that the powder hung on the wall inside is cooled when rotating to the outside of a beam scanning line, powder combustion caused by continuous irradiation is further avoided, the whole under-beam powder conveying is in a closed space, pollution caused by external dust is avoided, and continuous production is facilitated.

Description

technical field [0001] The invention relates to electron accelerator irradiation technology, in particular to under-beam device technology. Background technique [0002] With the continuous expansion of the application of electron accelerator irradiation technology, there are more and more requirements for the application of electron beam irradiation for powder materials. Bacteria; including material modification, such as irradiation degradation of industrial starch, cellulose degradation. In this process, the product transport equipment referred to as the under-beam device is required to transport the product to be irradiated to the bottom of the electron beam scanning box. However, the current mature under-beam devices are suitable for the modification of wires and cables and the transmission of packaged goods. For the continuous irradiation process of powdery objects, there is no safe and efficient under-beam device, which restricts the development of electron accelerato...
