Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in more detail.
Embodiment one, shown in Figure 1, present embodiments provide a kind of crosslinking pretreatment device for tire rubber sheet electron irradiation, comprise radiation chamber 1, screened room 2, electron accelerator 3, conveyer belt, electron accelerator 3 is arranged in radiation chamber 1, radiation chamber 1 comprises diapire 11, this diapire 11 has opening 1a, radiation chamber 1 is hemi-closure space, electron accelerator 3 is positioned at directly over opening 1a, screened room 2 is by screened room sidewall 12, and the diapire 11 of radiation chamber surrounds, conveyer belt comprises inducer 41, outlet section 42, radiation chamber level transportation section 43, the outlet linkage section 45 being connected to the import linkage section 44 between inducer 41 and radiation chamber level transportation section 43 and being connected between outlet section 42 and radiation chamber level transportation section 43, inducer 41 and import linkage section 44 and outlet section 42 and outlet linkage section 45 shape be in 90 ° ~ 120 ° of angles, radiation chamber 1 and screened room 2 inwall are all pasted with radiation absorption plate.The operation principle of the crosslinking pretreatment device for tire rubber sheet electron irradiation of the present embodiment is: conveyer belt is loaded with film, successively through inducer 41, import linkage section 44, arrive radiation chamber level transportation section 43, radiation chamber level transportation section 43 accepts the radiation treatment of electron accelerator 3, then through outlet linkage section 45, outlet section 42 exports, by arrange inducer 41 and import linkage section 44 and outlet section 42 in 90 ° with outlet linkage section 45 shape ~ 120 ° of angles, can greatly shorten screened room length, by being all pasted with radiation absorption plate on radiation chamber and screened room inwall, high energy electron can be absorbed and collide the ray that tyre film and conveyer belt produce.
High energy electron is squeezed in film, and rubber molecule is produced crosslinked, a part of electronics excites carbon atom at film face, and some electronics is got on conveyer belt, and this two parts electronics all will produce ray.In order to the X-ray preventing electronics from bombarding film and steel wire generation lets out along conveyer belt within the scope of 0 ± 2 °, plane, the sidewall 12 of diapire 11 junction with radiation chamber has radiation absorption groove 13, above-mentioned ray is irradiated in described radiation absorption groove along radiation chamber level transportation section, the secondary ray major part produced reflexes to screened room, produce secondary ray through at least 3 secondary reflections, the radiation absorption plate that energy major part conductively-closed chamber interior walls attaches absorbs.This radiation absorption groove 13 is preferably designed to semicircle, comprehensive acceptance can come ray within the scope of 0 ± 2 °, comfortable plane and secondary ray, by most of radiation in screened room, then carry out multiple reflections, to ensure that various ray is fully decayed.Described radiation absorption plate preferably adopts stereotype or steel plate.
In order to improve the order of reflection of ray at screened room further, reduce ray from outlet section volume reflection, ray diffraction groove 14 is had at the outer surface of the diapire 11 of radiation chamber, in above-mentioned steps, at least 3 secondary reflections produce secondary ray, reflect in described ray diffraction groove 14, reduce the intensity of 4 rays further.Described ray diffraction groove 14 is preferably triangular groove, therefore, only has 4 of summit place rays could reflect the outlet section described in arriving, can effectively reduce leakage radiation amount.Adopt this radiation screen shielding apparatus, x-ray through more than 5 times reflection arrive outlet, radiation leakage amount lower than country to environmental protection environmental requirement.In order to absorb secondary X-ray further, in described screened room 2, the side of import linkage section 44 and the side of outlet linkage section 45 have been horizontally disposed with at least one trap plate 6 respectively.In order to namely realize object, can cost be saved again, being preferably horizontally disposed with two trap plates 6 respectively in the side of the side of import linkage section 44 and outlet linkage section 45.
In order to reduce outlet section 42 place leakage radiation amount, at described outlet section 42 place, sidewall 12 outer surface of screened room is hinged with protective cover 8, when detecting once the radiation at outlet section place exceeds standard, this protective cover 8 is laid, can effectively stop that ray overflows, due to ray in screened room through multiple attenuation, the intensity arriving exit is also lower, therefore protective cover can adopt conventional low cost material as the realization such as plastics, wood materials, also can adopt the stereotype with radiation absorption function or steel plate materials.
In order to maximized shortening device length, inducer 41 and outlet section 42 is made to remain on level or nearly level, floating pinch roller 5 is respectively arranged with between inducer 41 and import linkage section 44, between outlet section 42 and outlet linkage section 45, the tensioning of conveyer belt is realized by the pinch roller 5 that floats, device length shortens to 3000mm, guarantee that the volume of maintenance area (corresponding to screened room 2 region) just can hold a maintenance personal simultaneously, realize saving shielding material more than 20 tons.
Shown in Figure 2, the maintenance of machine conveniently in radiation chamber and screened room, described screened room 2 has room door 7, and the internal cavity tool of screened room 2 has structure wide at the top and narrow at the bottom, ensure that screened room has enough service clearances simultaneously.
Certainly; above-mentioned explanation is not limitation of the present invention; the present invention is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement, also should belong to protection scope of the present invention.
