Electron beam radiation shield device based on continuous production

Abstract

The invention discloses an electron beam radiation shield device based on continuous production. The electron beam radiation shield device comprises a control module and a conveying assembly used forconveying a workpiece. The conveying assembly comprises multiple conveying rollers which are arranged at intervals. A shielding cover is arranged on the outer side of the conveying assembly in a covering manner. A conveying channel is arranged in the shielding cover, and a feeding opening and a discharging opening are formed in the positions, at the two ends of the shielding cover, of the conveying channel. The conveying channel comprises a feeding area, a radiation machining area and a discharging area arranged in the conveying direction. An electron beam accelerator is arranged in the radiation machining area. Two shielding assemblies are arranged in each of the feeding area and the discharging area. Each shielding assembly comprises a shielding door used for blocking the conveying channel and a driver used for driving the shielding door to be opened or closed. The distance between the two shielding doors in the feeding area and the distance between the two shielding doors in the discharging area are larger than the length of the workpiece. Each shielding assembly further comprises a workpiece inductor, wherein the workpiece inductor and the corresponding driver are connected with a control module. By means of the electron beam radiation shield device, the shielding effect is ensured, and meanwhile the stability and production efficiency of a production line are improved.

Description

technical field [0001] The invention relates to the technical field of electron beam curing, in particular to an electron beam radiation shielding device based on continuous production. Background technique [0002] During the process of electron beam irradiation, when the electron beam hits the irradiated object or the inner wall of the channel, it will generate x-rays harmful to the human body in the irradiation area. X-rays belong to ionizing radiation, which is different from non-ionizing radiation of visible light, Ultraviolet light (UV) is different in that it interacts with substances in a complex manner, and has rules such as reflection and transmission at the interface. In a production line capable of continuous production, how to shield the X-rays generated in the irradiation area to a safe level is the primary safety issue in production line design. [0003] The method adopted in the prior art is: place the accelerator electron beam equipment in the center of the...

Problems solved by technology

However, due to the existence of ups and downs and turns in the labyrinth channel, the stability of the production line will be reduced, and the running speed of the production line will also be reduced to a certain extent, resulting in a reduction in production efficiency.

In addition, a shielding structure that is at least 7 times the length of the workpiece is required to ensure the self-shielding effect, which requires a lot of shielding materials and site space
