Technical Field

The invention relates to the field of reactor accessories, in particular to a nuclear waste barrel.

Background

Nuclear waste refers to useless material containing unstable elements of alpha, beta and gamma radiation accompanied by heat generation. The nuclear waste can cause pollution of water, atmosphere and soil after entering the environment, and can enter human bodies through various ways, when radioactive radiation exceeds a certain level, cells of organisms can be killed, normal cell division and regeneration are prevented, and mutation of genetic information in the cells is caused, so that the nuclear waste is usually stored in a special container, and a nuclear waste barrel is a container for reducing the volume of solid radioactive waste and storing liquid radioactive waste condensate of a nuclear power plant.

At present, chinese patent publication No. CN207425383U discloses a disposal container for radioactive waste barrels of nuclear power plants, which comprises a box frame, including a box side wall and a box end wall, and having equal length and width; the bottom plate is fixedly connected with the bottom of the box frame; a partition plate provided on the bottom plate to divide the bottom plate into N rows of xN columns of cells, N being 3 or 4, in each of which one metal trash can is placed, and when N is 3, the partition plate divides the bottom plate into 3 rows of x3 columns of 9 cells, in each of which one 400L metal trash can is placed, and when N is 4, the partition plate divides the bottom plate into 4 rows of x 4 columns of 16 cells, in each of which one 200L metal trash can is placed; and corner fittings arranged on corners of the box frame; wherein the height of the box frame is higher than that of the metal waste barrel.

Although the nuclear power plant radioactive waste barrel disposal container is stacked when final disposal is carried out, the replacement of the gripping apparatus is reduced, the stacking efficiency and the space utilization rate are high, the engineering cost is low, the irradiation time and the dosage of workers can be obviously reduced, and when the processes such as extrusion treatment and the like are carried out on the nuclear waste barrel, the sealing cover of the barrel is prone to tilting and the like, so that nuclear waste is leaked.

Disclosure of Invention

The invention aims to provide a nuclear waste barrel which has the advantage that the situation that the sealing cover is tilted to cause leakage of internal radioactive substances in the subsequent extrusion and compression processes can be effectively reduced.

The technical purpose of the invention is realized by the following technical scheme:

the utility model provides a nuclear waste bucket, includes the staving, still be equipped with the bung on the staving, still be equipped with sealing device on the bung, sealing device includes that the usage wraps up staving top and bung closed hoop all around and is located the tight device that seals of closed hoop top, seal tight device including be located the opening that seals on the hoop, be located the first joint that opening one side was equipped with, be located the second joint that opening opposite side was equipped with, connect articulated handle and both ends respectively with first joint and the articulated connection piece of handle with the second.

Through adopting above-mentioned technical scheme, the sealing device that is equipped with can effectual whole staving of sealing to the circumstances such as reveal appear in the reduction, and after the closing cap lid is good, can effectually make closing cap and staving form a whole through the closing device, wait until subsequent extrusion, when flattening the process, even press whole staving into the platykurtic, inside radioactive raw materials can not leak out yet, thereby the effectual reduction appearance radioactive material reveals the condition that influences the environment and takes place.

Further setting: the edge of the top end of the barrel body is provided with a curled extending edge, and the periphery of the barrel cover is positioned above the extending edge.

Through adopting above-mentioned technical scheme, the tight of being equipped with and with the bung card on extending, and because the closure hoop wraps up whole extending and bung all around together to when flattening, can effectually block whole closing cap, simultaneously because whole bung edge demonstrates the state of crouching, consequently squashing to both sides when it carries out the state of pushing down the process crouching, the reduction appearance closing cap is in the condition of flattening the in-process by bounce.

Further setting: the second joint is hinged with the handle through a hinge device, the hinge device comprises a base positioned on the closed hoop, first semicircular head rivets positioned on two sides of the base and rotatably connected with the closed hoop, and second semicircular head rivets positioned between the bases and rotatably connected with the handle

Through adopting above-mentioned technical scheme, the second that is equipped with connects bung hinging device and is connected with the handle, and the first rivet of semicircle that is equipped with can effectual rotation, reduces the later stage extrusion in-process simultaneously and appears collapsing out, the appearance of the circumstances such as closing cap that breaks.

Further setting: two reinforcing ribs are uniformly distributed on the barrel body.

Through adopting above-mentioned technical scheme, the strengthening rib that is equipped with can be effectual when the staving is flattened, reduces the staving and appears breaking the circumstances such as for the effectual extrusion by of staving.

In conclusion, the invention has the following beneficial effects: can effectual placing radioactive object to flatten in follow-up extrusion process, reduce simultaneously and flatten the in-process closing cap perk or pop out and lead to appearing revealing the circumstances such as, greatly increased the stability and the security of staving.
