Description

A kind of novel radiation device

This utility model relates to a kind of irradiation devices.

In the past few decades, utilize the stifling sterilizing pesticide that carries out agricultural byproducts and food of chemical agent extensively to be adopted, but, actively develop irradiation technique both at home and abroad because chemicals is serious day by day to the harm of human health and environment for human survival by people.At present, irradiation technique has been widely used in fields such as industry, agricultural, environmental protection, food and health care.Wherein, the irradiation of food and people's life is closely related.The irradiation of food is mainly used in the parasite killing of agricultural byproducts and fresh-keeping, the sterilization of food and fresh-keeping, aspects such as the quarantine sterilization of import and export food.The irradiated food joint specialist committee of in October, 1980 FAO (Food and Agriculture Organization of the United Nation) (FAO), The World Health Organization (WHO), three tissues of International Atomic Energy Agency (IAEA), according to more than the 30 year wholesomeness result of study in various countries, issued that any food at the following irradiation of 10kGy all is safe conclusion, this conclusion has played important impetus to the development of the food irradiation technique of various countries.

Existing irradiation devices comprise isotope irradiator plant and accelerator irradiation device two big classes.These irradiation adopt fixed centralized management usually, and irradiation devices are placed in the specific radiation chamber.So just need deliver to the appointed place to irradiated material by a dead lift and carry out irradiation.This will inevitably bring operational trouble, gives to apply in fields such as agricultural, industry, food and health care and makes troubles.In addition, use this method to need manual feeding, each irradiation limited amount, irradiation process and feeding process time-division processing, each exposure time is long at interval, is unfavorable for the irradiation of continuous and automatic like this, reduce irradiation efficiency, be not suitable for being applied in the occasion that needs a large amount of irradiated materials.

The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art part, and a kind of irradiation efficiency height is provided, and is easy to use, easier applying, and can realize the irradiation devices that irradiation automatization handles.

To achieve these goals, solution of the present utility model is: a kind of novel radiation device, comprise deliver goods device, radiological unit, screening arrangement and connect the goods device, it is characterized in that: also have conveyor-belt apparatus in addition, this device is made up of conveyer belt, drive and drive motors.

After adopting as above scheme, following advantage is arranged: owing to use conveyer belt to transmit irradiated material, can saving the carrying link, that people are used is more convenient: and the conveyor-belt apparatus simple installation, it is less to take up room, expensive few, easy to utilize.In addition, a certain link during it can be applicable to produce or be applied to the automatization that other occasions realize overall processes and handle realizes continuous feed, and continuous irradiation improves irradiation efficiency.

Fig. 2 is the sketch map of another embodiment of this utility model;

Fig. 3 is the sketch map of the 3rd embodiment of this utility model.

Below in conjunction with accompanying drawing this utility model specific embodiment is described in further detail.

In Fig. 1 specific embodiment of the present utility model as can be known, the conveyor type irradiation devices comprise: deliver goods device 1, radiological unit 5, screening arrangement 6, connect goods device 3, conveyor-belt apparatus 4 etc.Wherein conveyor-belt apparatus 4 is made up of drive 9, conveyer belt 10 and drive motors etc., and it is used for delivery and transmits irradiated material and deliver to radiological unit 5 places and carry out irradiation.Deliver goods device 1 is used for stored article and it is delivered to conveyer belt 10, and it can be funnel, mechanical hand or carrier pipe etc.Radiological unit 5 can be isotope irradiator plant or accelerator irradiation device, is used to produce radiation and is radiated assigned address, and it is placed in the inside of screening arrangement 6; And screening arrangement 6 is made up of barrier shield 7 and shielding sheet 8, and the internal layer of screening arrangement 6 is a pmma material, and skin is copper or lead material, is used to shield ionizing radiation, reduces the pollution to surrounding; The both sides of barrier shield 7 have two square holes 11, top square hole 11 broads are the transmission channel of irradiated material and the via hole of conveyer belt 10, settle a shielding sheet 8 respectively in its both sides, it be a thin slice and with barrier shield 7 for flexibly connecting, be used for preventing that radiation from letting out from square hole 11.Below shielding sheet 8 is conveyer belt 10, and there is a rotary pulley it and shielding sheet 8 smooth contacts in the bottom of conveyer belt 10; , it is installed on the upper surface of top square hole 11, contact or fixedly connected with barrier shield 7 is smooth, and with conveyer belt 10 smooth contacts.And following square hole 11 narrower be the via hole of conveyer belt 10, and conveyer belt 10 contacts with upper and lower surface is smooth herein.At conveyer belt 10 and connect between the goods device 3 and to place a guide groove 2, can be used for article are imported from conveyer belt 10 and connect in the middle of the goods device 3.This guide groove 2 and conveyer belt 10 with connect goods device 3 smooth contacts.Connect goods device 3 and be used to receive irradiated article and be responsible for it is transported to the appointed place, it can be funnel, mechanical hand and carrier pipe etc.

Fig. 2 is another embodiment of the present utility model, its difference from Example 1 is that it uses another kind of screen method, the contour structures of screening arrangement 6 as shown in Figure 2, be placed with radiological unit 5 at an upper portion thereof, the bottom is a hollow radial chamber, it is the upside down funnel shape, as the radiation chamber of irradiated material, and can prevent effectively that radiation is excessive.The bottom of screening arrangement 6 is dual cylinder, and both sides have square hole 11, as the transmission channel of irradiated material and the via hole of conveyer belt 10, uses double shielding sheet 8 at square hole 11 places, and it can prevent effectively that radiation from leaking outside.This shields sheet 8 and conveyer belt 10 smooth contacts, and the top of conveyer belt 10 is passed from square hole 11, and the fixed in shape of conveyer belt 10 one-tenth as shown in the figure, and article can be input in the radial chamber of screening arrangement 6 from the slope 12 of conveyer belt 10.

For another shown in Figure 3, the difference of this embodiment and embodiment 1 embodiment 2 is conveyor-belt apparatus 4 is placed on the inside of barrier shield 7 and the method for use dual shield fully, be with two-layer barrier shield 7 at radiological unit 5 outer, it is placed in the upper cavity of internal layer barrier shield 7, and and barrier shield 7 be placed on together conveyer belt 10 directly over.The bottom of barrier shield 7 is an inverted funnel-form, is used for the radiation-screening line.Conveyor-belt apparatus 4 is placed on the inside of outer barrier shield 7.Have square hole 11 in the both sides of outer barrier shield 7, be provided with shielding sheet 8 in the bottom of both sides square hole 11, and place a guide groove 2 respectively in the bottom of both sides shieldings sheet 8, this guide groove 2 smooth surfaces, and support by outer barrier shield 7, and with conveyer belt 10 smooth contacts; It is used for irradiated material being imported on the conveyer belt 10 and article being derived from conveyer belt 10.

Certainly, this irradiation devices screen method is not limited to above three kinds of embodiment, if having other therewith utility model embodiment conceive consistent irradiation devices and also belong to protection domain of the present utility model.
