Problems solved by technology

During the compaction process, the barrel-carrying trolley bears the pressure of the press and transmits it to the track. At the same time, the barrel-carrying trolley frequently shifts and loads

Embodiment Construction

[0021] The present invention will be described in further detail below through specific examples.

[0022] A compaction treatment method for micro-radioactive waste. The compaction treatment is completed on a four-column compactor, and the compaction action is carried out in a compaction chamber 22 in a closed state. The door 17 and the exhaust port 21, the exhaust gas in the compaction process is discharged from the exhaust port 21 to the central processing system for processing, which includes the following steps;

[0023] A. The lifting door 18 of the in-out bucket is in an open state, and the waste bucket 11 is fixedly installed on the in-out bucket slider 14 outside the compaction chamber 22;

[0024] B. Pull the barrel slider 14 to make the waste barrel 11 enter the compaction chamber 22 and put it in place, and the pulling action is realized by the push-pull cylinder 12;

[0025] C. Close the lifting door 18 of the in-out bucket, and the transition bucket 8 installe...

Abstract

The invention discloses a method for compacting and treating micro-radioactive waste. The method includes A, fixedly mounting a waste barrel on a barrel access slider outside a compaction cavity when a barrel access lifting door is opened; B, pulling the barrel access slider so that the waste barrel enters the compaction cavity to be in position; C, closing the barrel access lifting door, shifting a transition barrel mounted in the compaction cavity and enabling a lower opening of the transition barrel to match with an upper opening of the waste barrel; D, opening a feeding door and feeding materials into the waste barrel at one step; E, closing the feeding door, enabling a pressure head of a compactor to move downward, compact and maintain pressure; F, repeating the step D and the step E until waste in the waste barrel is sufficient when the pressure head ascends and returns, and stopping feeding; and G, lifting the transition barrel, opening the barrel access lifting door and pushing the barrel access slider to lead out the waste barrel. The method is simple in operation, operation steps are reduced, operation efficiency can be greatly improved, failure rate is reduced, the service life of equipment is prolonged, and radiation pollution to operators is reduced.

Description

technical field [0001] The invention relates to a waste mechanical packaging technology, in particular to a compaction treatment method for micro-radioactive waste. Background technique [0002] At present, domestic nuclear power plants mostly use imported (Russian, German, etc.) equipment for volume reduction and compaction treatment of waste. The main engine outside the hydraulic station is a box-type structure, and the external dimensions are mostly 5500L*1500B*5000H. The used compactors are purchased The period is more than one and a half years, and the price of a single machine is more than 500,000 US dollars. It not only requires the equipment department to have excellent foresight, but also uses excessive foreign exchange, which to a certain extent inhibits the development and promotion of compaction balers in this industry in China. The processing method of foreign equipment is to lay the track along the bottom of the length direction, and the track car barrel is fed...
