The utility model has the advantages of effectively lowering the expenditure of construction of radiation protection and improving protection effect of the per unit screening material due to the semi-underground irradiation protection design; of raising operating factor of surficial field and meeting the requirement of protection design of large objects under continuous irradiation; of improving the screening protection effect of the whole device, in particular the safe effect of gateway of the irradiated object.
Description
Technical field
The utility model relates to a kind of protective device, particularly relates to a kind of protective device when utilizing accelerator to carry out radiation treatment.
Background technology
China has a large amount of logs to need import at present, but in log, have overseas harmful organism, animals and plants and various microorganism usually, endangering the healthy and safe of people, the irradiation technology of removing the evil is a state-of-the-art disinfection technology in the world today, and he is that the X ray that utilizes gamma-rays that radiation isotope cobalt 60, caesium 137 produce or low energy accelerator to radiate carries out radiation treatment to goods.Because the irradiation sterilization sterilization almost can be eliminated any virus and bacterium fast, wherein Chinese patent " 02121445.X " carries out the car load processing by irradiation technique to large log, and log does not need to unload and can finish irradiation quarantine.But there is following shortcoming in this scheme: the car load irradiation quarantine makes and is in the irradiation that the log that loads the centre can't obtain sufficient dosage, make irradiation quarantine the blind area occur, the homogeneity of irradiation dose is not good enough, even be subjected to the log of irradiation, it is subjected to the also inhomogeneous of irradiation dose, radioactive dose is excessive to be a kind of waste of the energy, does not have a quarantine effect and radioactive dose is too small; In addition, this patent is that four accelerators contrast mutually, can cause very big mutual damage between the relative accelerator, has a strong impact on the serviceable life of accelerator.The accelerator that this scheme is used adopts the use-pattern of open type, and accelerator produces the scattering of high-energy ray, can propose very high requirement to radiological safety protection.The gateway of whole device is particularly very easily caused being strayed into of personnel and great radiological safety accident is taken place; This scheme only is confined to have the area of railway, is subjected to the region restriction during construction, is not suitable for railway area in addition and uses.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of with low cost, protection safety is provided, and is suitable for the radiation protection device that various area surroundings use.
The technical scheme that the utility model adopted is: a kind of protective device of semi-underground type radiation treatment, comprise: accelerator, photographed object product drive unit and the irradiation Room, the main body in the described irradiation Room is arranged on underground, described accelerator body device is arranged on the ground, the bundle lower device of accelerator, bundle underdrive device and be arranged on underground by the movable passageway of irradiated material in the irradiation Room.
The below of described accelerator is provided with the bundle lower device, and described bundle lower device is positioned at the top in the irradiation Room.
Described photographed object product drive unit comprises gearing and rotating device; Described gearing is mechanical haulage or control automatically.
The irradiation Room inwall of described sealing is provided with barrier shield, and the barrier shield in the middle of the described irradiation Room is the jatharapanvartanasana structure.
Described accelerator quantity is one.
The beneficial effects of the utility model are: because the design of semi-underground type radiation protection is adopted in the utility model design, can effectively reduce radiation proof expenditure of construction, improve the protection effectiveness of unit shielding material.Improved the utilization factor in place, the face of land.This programme can also solve the protection designing requirement of large item continuous irradiation simultaneously.Improved the shielding protection of whole device greatly, particularly the safe effect of photographed object product gateway.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail: as shown in Figure 1 to Figure 3, the protective device of the utility model radiation treatment comprises: accelerator 7, drive unit, screen protective device.Described bogey 3 is used to place large item such as log 2 etc., 6 are provided with described accelerator 7 in the described irradiation Room, accelerator 7 quantity are one, avoided many accelerators problem of damage mutually, prolonged the serviceable life of accelerator, the below of described accelerator 7 is provided with bundle scanning window 1 down, described bundle scanning window down is one or two, vertical mutually setting the when two scanning windows, described bundle scans the upper end that window is positioned at the irradiation Room down, and bundle scanning window down has electron beam or X-ray production apparatus to penetrate from window.Described drive unit comprises gearing and rotating device; Described gearing is mechanical haulage or control automatically; Described rotating device is the power roller, is arranged on the baseplane of bogey 3; The gearing that moves can be electric automatic control or mechanical haulage mode; Wheelwork when described grid guardrail bogey 3 at the uniform velocity advances under the tractive force effect on the bogey starts the irradiation thing and carries out at the uniform velocity rotation, at the uniform velocity the wasting of resources that causes because of the dose distribution inequality has effectively been avoided in rotation, the irradiation thing is example with the log, pace and rotational speed can be decided according to the output power of accelerator at that time and irradiation thing, have avoided the irradiation quarantine blind area of causing of batch processing.Wheelwork on the bogey can make the log rotation of rolling along the axle center for the power roller.The irradiation Room inwall of described sealing is provided with barrier shield 4, barrier shield 4 in the middle of the described irradiation Room 6 is the jatharapanvartanasana structure, and revolving structure specifically is not restricted to arbitrary structure, as long as can satisfy the needs of Safety Design, the leakage that effectively prevents radiation gets final product, and environment does not exert an influence to external world.The agent set of this screen protective device is positioned under the face of land simultaneously, and this design both can utilize the earth to play shielding action fully, and then reduced to shield the expense of construction.This scheme also can reduce the occupation of land on the face of land simultaneously, can economize out more space and be used for logistics turnover occupation of land or environmental greening construction.
Principle of work of the present utility model is: the large item that need carry out radiation treatment, as log, can descend by the overhead traveling crane 5 at place, gateway and dock on the bogey of locating under the face of land, gateway, the irradiation Room, and the photographed object product are moved along the rotary type path passage between the barrier shield in the irradiation Room by draw-gear, the place carries out radiation treatment at accelerator bundle lower device, article after the processing are carried by bogey, and under the drive of draw-gear, continuation is moved along the rotary type passage, locate to the gateway, by overhead traveling crane 5 its rise is brought to the face of land and locate other related device place, finish the irradiation treatment process process one time.
When a certain photographed object product carried out radiation treatment on the bogey in the irradiation Room, overhead traveling crane can carry out the lifting of other article simultaneously or transfer, and by adjusting the cycle of operation of each parts in this device, thereby had realized the continuous running of whole device.
