High shielding large-scale shielding cabin

Abstract

The invention relates to a high shielding large-scale shielding cabin. The shielding cabin is a rectangular hexahedral structure, two sides of the shielding cabine are log access cabin doors, the cabin is internally provided with a tray conveying belt and a supporting beam, the cabin is internally provided with a waveguide antenna feed system vertically, the antenna feed system is led out through a special-purpose waveguide opening to connect with a microwave generator outside the cabin, the cabin is further internally provided with an illumination lamp, a monitoring probe, a mode stirrer and a temperature sensor which are respectively provided with a cabin wall through hole, the ground surface of the shielding cabin has a drainage microwave cut-off channel for draining residual water, and the cabin is internally provided with an exhausting dehumidification system. The shielding cabin employs a full welding shielding mode, each opening link of the shielding cabin has an excellent shielding means, the shielding cabin reaches prescribed international limit values, heat insulation, heat preservation, corrosion prevention, salt spray prevention and decoration processing on the outer cabin surface are carried out, microwave energy loss of the cabin can be reduced, ignition can be avoided, and fixed bearing conditions can be provided for waveguide equipment.

Description

technical field [0001] The invention relates to the field of shielding cabins, in particular to a large shielding cabin with high shielding performance. Background technique [0002] China is not only a big timber producer, but also a big timber consumer and a big exporter of wooden furniture. For a long time, the resource supply of China's timber industry has been based on natural forest resources. After the Chinese government implemented the natural forest protection project in 1998, the state implemented a ban on natural forest resources in key state-owned forest areas such as Southwest State-owned Forest Areas, Northeast China, and Inner Mongolia. , Restricted logging policy. In January 2014, the State Forestry Administration issued the "Notice on Doing a Good Job in the Pilot Work of Completely Stopping Commercial Logging". It is clearly required to completely stop commercial logging in key forest areas such as the Greater and Lesser Khingan Mountains and Changbai Mou...

Problems solved by technology

At present, domestically imported container logs are also treated with chemical methyl bromide fumigation technology. There are three main disadvantages in this treatment method. One is that methyl bromide is a toxic gas, which will cause serious air pollution, especially the destruction of the ozone layer; Methyl bromide will cause harm to the health of personnel and does not meet occupational health requirements; third, it takes 24 hours to fumigate a container log with methyl bromide, which increases the turnover link and reduces production efficiency
