Abstract
The utility model relates to an irradiation system with a cobalt-60 radiation source temperature-reducing device, comprising a radiation source frame, a radiation source, a source frame protective cover and an air vent and further comprising a water pump, a water-absorbing pipe, a water-discharging pipe and spraying heads, wherein the water pump is arranged at the bottom of the air vent; an absorbing port of the water-absorbing pipe is placed in a source water storage well; and the water discharging pipe is connected with the spraying heads which are arranged at the periphery of the top end in the source frame protective cover. When the irradiation system works, the radiation source is lifted to a water surface working position from stored position of the water well, water stored in the water well is pumped by the water pump, the water discharging pipe is connected with the spraying heads at the periphery of the top in the source frame protective cover so as to carry out spraying and temperature reduction on the inner walls of the source frame protective cover and block the radiation source from transferring heat into an irradiated goods box from the source frame protective cover, and sprayed water still returns into the well. The irradiation system has the obvious characteristics that the structure is simple, the temperature reduction is fast, and safety and reliability are achieved.
Description
Technical field
The utility model belongs to the irradiation processing field, is specifically related to a kind of irradiation system that has cobalt-60 radiation source heat sink.
Background technology
Radiosterilization sterilization processing is to utilize ionising radiation (comprising the particle beams that nuclear radiation that radioactive nuclide produces and accelerator produce) and material or material physics, chemistry or the biology that produces that interacts to change, and material or material is processed the process of processing.Usually the radiosterilization sterilization mainly refers to
60The Co radiation source or
137The gamma-radiation that Cs produces carries out RADIATION PROCESSING to be handled, and makes photographed object reach desinsection, mildew-resistant, sterilization, sterilization, improves the health quality, and food storage is fresh-keeping, purposes such as material property improvement.
Because of cobalt-60 radiation source energy of height, self can distribute and produce a large amount of heats, the radiation source radioactivity is high more, and the heat that the radiation source surface produces is big more, occurs too high causing of source temperature easily to transfer heat in the radiation exposed cargo compartment from source frame protective cover.
Summary of the invention
The utility model provides a kind of irradiation system that has cobalt-60 radiation source heat sink, carries out spraying cooling by spray head around the frame protective cover inner top of source, can effectively solve the cooling difficult problem of radiation source so that cobalt-60 radiation source fast cooling.
A kind of irradiation system that has cobalt-60 radiation source heat sink, comprise radiation source frame, radiation source, source frame protective cover and ventilating opening, described radiation source frame and radiation source all place in the frame protective cover of described source, wherein, also comprise water pump, suction hose, rising pipe, spray head, described water pump is installed in the bottom of described ventilating opening, the suction inlet of described suction hose is placed in the well of storage source, described rising pipe is connected with spray head, described spray head be installed in top in the frame protective cover of described source around.
Described ventilation road junction is located near the frame protective cover of described source.
The start-up control switch of described water pump is located in the outer operation pulpit of irradiation system fender wall, is connected with the radiation source lifting gear.
Described source frame protective cover can be made with hard aluminium alloy, aluminium sheet or stainless steel materials, and described suction hose, rising pipe and shower are all made of stainless steel.
The irradiation system that has cobalt-60 radiation source heat sink of the present utility model, when radiation source when water surface working position is mentioned in well storage position, by the water in the well of water pump extraction storage source, be connected with spray head around the frame protective cover inner top of source by rising pipe, source frame protective cover inwall is carried out spraying cooling, blocked radiation source and transferred heat in the radiation exposed cargo compartment from source frame protective cover, the water behind the spray is still got back in the well of storage source.The outstanding feature of this device is simple in structure, and cooling fast, and is safe and reliable.
Description of drawings
