Abstract

The utility model belongs to the processing equipment of solid low radioactive pollutants. The radioactive pollutants are compressed and packed in a metal container for the convenience of further processing. A compressing packaging machine is mainly composed of a rotatable press head driven by a compressing cylinder, a rotary chasis driven by a motor and an edge-curling cover-sealing mechanism, wherein, the rotary chasis is arranged on a slide seat, and an exhaust duct which is connected with an external system is arranged on the press head. After the pollutants is thrown in the metal container, the pollutants are in volume reducing compression by the press head, and the harmful gas is exhausted to a processing system through a channel on the press head. After the container is filled, the container is sealed by the edge-curling cover-sealing mechanism.

Description

Compression packaging machine for low-radioactive contaminant

The utility model belongs to what treatment of radioactive pollutant device, is a kind of equipment that solid low-activity pollutant is compressed encapsulation.

At present to solid low-activity pollutant, as the processing of examining the old and useless articles such as cotton yarn, working cloth, gloves, rubber and plastic article (as raincoat), leather shoes and paper products in operation place is to put it into to be embedded in undergroundly in the closed container, but this loosely is too big with the refuse shared volume of container of packing into.Have plenty of refuse is packed into behind the container again with the compression of integral container ground, so that reduce volume.But this class gas booster compressor volume is big, and can't move, and refuse can only be concentrated on a fixed-site and handle, and this processing for the pollutant in some nuclear operation place is very inconvenient.

The purpose of this utility model provides a kind of solid low-activity pollutant can being compressed in the container, and can carry out the compression packaging machine of capping to this container.

Solution of the present utility model is: the low-activity pollutant compression packaging machine that is provided has a vertical frame support, cantilever tip is equipped with compression cylinder, rotatable dish type pressure head is housed on the piston rod of this oil cylinder, and pressure head is provided with the exhaust passage that links to each other with external filtration system; The driving mechanism that a slide and slide are arranged on the guide rail of bracket base, slide are provided with a swivel base by motor driven; Be provided with the crimping capping mechanism in the support side.Canister places on the rotating disc during work, and the pollutant oil cylinder of packing into behind the container drives pressure head pollutant is compressed, and then drops into pollutant to container and compress, and repeatedly compression is filled in container till the pollutant of compression and so forth.Compression finishes container cover is covered, and pressure head is pressed on it on vessel port, and the container of motor driven chassis, and drive then rotates together, by the crimping capping mechanism vessel port and container cover is carried out crimping, is sealed.The entry and exit of container are to be finished by moving of slide.In addition, the volume-diminished of pollutant will be discharged some gases in compression process, and can produce some dust, and these materials are to be discharged into outside filtering system by the exhaust passage on the pressure head, to prevent the injury of radiomaterial to the operator.

The utility model adopts toward the working method of compound compression pollutant is encapsulated in the container, its compact conformation, and the volume of entire equipment is less, can be contained on the motor vehicles, and this has just significantly reduced the processing links of pollutant, and disposal cost is lower.

Below in conjunction with accompanying drawing content of the present utility model is illustrated.

Fig. 1 is one-piece construction figure of the present utility model.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the synoptic diagram of double seaming closing machine structure.

As shown in Figure 1 and Figure 2: frame support 1 is made up of four root posts 2, top board 3 and base 30, and 3 on column 2 and top board are connected with nut 5, can adjust the high and low position and the horizontal accuracy of top board by nut 5.The end of compression cylinder 6 is installed in the top board center, and pressure head 7 is housed on the piston rod of oil cylinder 6, this pressure head 7 by Moving plate 8, price fixing 9 and be positioned at Moving plate and price fixing between taper roll bearing 10 and single thrust bearing 11 form.Above-mentioned price fixing 9 is fixed with the oil cylinder piston bar, and is not rotatable in entire work process; Moving plate 8 seals in the process and can rotate with canister 12 at crimping.In order to hold the effusion that prevents harmful gas in the compression process subtracting of pollutant, be provided with O-ring seal 13 in the periphery of price fixing 9, it and container inner wall closely cooperate, and harmful gas is enclosed in the container chamber.In compression process, harmful gas does not enter wireway 14 by bleeder vent and exhaust passage (the drawing among the figure) of pressure head Moving plate 8 end faces, enters outside filtering system by wireway 14 again and handles.In addition, on pressure head 7, also be provided with two guideposts 15, in order to increase the stability of ram movement.A slide 16 is arranged on the guide rail 4 of bracket base, and it places (see figure 2) on the roller 17 on guide rail 4 both sides, and its driving mechanism is an oil cylinder 18.The top of slide 16 is provided with swivel base 19, its structure is similar to pressure head 7, also be made up of price fixing, Moving plate and the taper roll bearing between price fixing and Moving plate and single-direction balls bearing, wherein price fixing is fixed on the slide 16, and Moving plate is connected with the oil motor 20 of slide bottom.During work, from the outside of support 1 canister 12 is placed on the chassis 19, drives slides 16 with oil cylinder 18 again, make container 12 enter station, start compression cylinder 6 then, pollutant is subtracted hold compression, this process vessel 12 is motionless.Container moves in order to prevent to compress, and also is provided with manual spring-loaded pawl 21 on chassis 19, and they are stuck on the convex edge of container bottom.

Double seaming closing machine structure 22 is positioned at the upper side of support 1, its structure such as Fig. 2, shown in Figure 3: it is made up of crimping wheel 23 and driving oil cylinder 24, contact roller 25 and driving oil cylinder 26 thereof.Pressure head 7 is pressed on container cover on the vessel port when sealing, and starts oil motor 20 then and drives chassis 19 rotations, and container 12, pressure head 7 will rotate thereupon together at this moment.Start oil cylinder 24 and oil cylinder 26, make that crimping wheel 23 and contact roller 25 are traversing successively to put in place, crimping wheel 23 twists in vessel port limit and lid together, and 24 of contact rollers further compress the limit of spooling, and finish the work of sealing.Number 27 among the figure---hydraulic system, 28---electrical control cabinet, 29---operator's console.

This compression sealing machine is mainly used in treatment of radioactive pollutant, and the compression that also can be used for other solid waste is handled.
