JPS59207326A - Discharging device for matter contained in drum - Google Patents

Abstract

PURPOSE:To improve safety, by a method wherein, in a discharging device for drum containing a radioactive substance-contained waste, the drum opening side is enclosed with a hood on a rotatable and elevatable frame, and the drum is forced to turn sideways to connect it with a discharge hopper through the hood. CONSTITUTION:A drum 4 containing a waste matter is carried onto a roller conveyor 50 on a frame 5 to connect a first shutter 9 to a hood 6 through the medium of a gasket with the aid of a power jack 52 to enclose the drum 4. Thereafter, the drum 4 is turned by 180 deg. together with the frame 5 to cause a valve 7 to be positioned opposite to an opening part 80 of a hopper 8. The frame 5 is then lowered through the working of a power jack 34 to connect the valve 7 to the opening part 80. On-off valves 75 and 76 of the valve 7 and a second shutter 81 are opened, a waste matter is dropped in the hopper 8, and a third shutter 83 is opened to discharge it from a quantitative discharge device 82. This constitution enables prevention of scattering of the waste matter and improvement of safety.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a discharge device for discharging waste containing radioactive materials or contaminated with radioactive materials from a drum can. Radioactive waste such as incinerated ash, crushed earth and stones (concrete blocks, ceramic filter blocks, etc.), and metal pieces are stored in drums for temporary storage.

These wastes need to be treated in some way for long-term stable storage. This requires removing the waste from the drum and transferring it to a hopper. In this case, the waste in drum C1 contains radioactive materials or is contaminated with radiation (because it is contaminated with radioactive materials, secondary contamination and dust scattering will occur when taken out). Don't avoid (J).

There are several methods to remove the contents from inside the drum, such as using an IJ or suction pump, or using a bucket to remove the contents safely. I can't take it out.

This invention has been developed to overcome these conventional drawbacks.

Below, an actual example of this invention is shown with drawings.
, FIG. 1 (13J, and FIG. 2) - C1 A rotating ring 3 is rotatably supported on the support "1-RA 2" installed on the base 1, and the frame 5 is supported by this rotating ring 3. In other words, the frame 5I is rotatably held by a supporting means (hereinafter referred to as "holding means") consisting of a J-ra 2 and a rotating ring 3. A pair of stoppers 35 are formed on the outer periphery of the rollers 31, and when the stoppers 35 come into contact with the support roller 2, the upper position shown in the figure is maintained.
It is constructed so that 1800 rotations can be made between the opposite downward position and the downward position.

A hopper 8 is arranged on the lower side of the rotating ring 3 with the opening section 80 facing upward, and the opening section 801.
The ivy 81 has become obsolete. The valve 7, which will be described later, is suspended from the hopper 8ca clay plate 1 by a spring 84.
It is designed to provide a buffering effect when connecting with the An opening at the lower end of the hopper 8 is provided with a metering discharger 82 and a third vine 83.

Further, the rotating ring 3 is provided with a kite rail 32 and a lowering power jack 34 (second drive means),
