In-barrel compacting device for radioactive solid waste

Abstract

The invention relates to a solid waste compacting device, and provides an in-barrel compacting device for radioactive solid wastes used in small space. The device comprises a rack, a feed opening arranged on a waste generating region, a waste slide communicating the rack and the feed opening, a damper gate of a rack in-and-out barrel panel, a linear guide rail arranged on the bottom of the rack todelivery in and out a steel barrel, a multi-stage electric cylinder which is on the top of the rack and is connected with a compacting disk, a high-pressure vortex fan which is on a corner of the topof the rack and is connected with an exhaust port, a garbage bag holding box in the rack, an automatic bag cutting and sealing mechanism, and a 200L steel barrel. The device is convenient in operation, proper in appearance dimensions, and high in reliability, and effectively reduces generation of secondary wastes, and reduces contact of workers on radioactive contamination.

Description

technical field [0001] The invention relates to a waste compacting device, in particular to a radioactive solid waste internal compacting device used in a small space. Background technique [0002] A large number of labor insurance products will be produced during the operation, maintenance and decommissioning of different nuclear facilities, and these labor insurance products will have different degrees of radioactive pollution. If the radioactive dose exceeds the recyclable standard, these labor insurance products containing traces of low radioactivity will be What has no use value becomes waste. These wastes cannot be equated with wastes that have not been radioactively contaminated. They can be simply shredded-packaged-stored or incinerated without special control, while wastes that have been subjected to trace amounts of radioactive contamination need to be classified separately and processed in separate equipment. It needs to be isolated and temporarily stored separat...

AI Technical Summary

Problems solved by technology

[0003] At present, the traces of low-level radioactive waste produced by nuclear facilities at home and abroad are basically packaged by compaction and volume reduction. Most of the compaction equipment in barrels at home and abroad are driven by oil cylinders, which need to be equipped with a large and complex hydraulic system, and the equipment has large dimensions; Many positions are set next to the equipment, which increases the possibility of operators being exposed to radioactive contamination

For example, CN202573035U uses an oil cylinder to drive vertical lifting for compaction, and a return oil tank is set on the frame, and the sliding block for entering and exiting the barrel and the lifting door are driven by an air cylinder. Not only the hydraulic system needs to be configured, but also an additional air source is required. The pipeline is complicated and occupies a lot of space. It is large and inconvenient for later maintenance; it sets the feeding door on the feeding panel of the device, although the feeding process is simplified, the operator still needs to perform feeding beside the device
