Abstract
Description
Technical Field
[0001] This invention relates to an irradiation device. Specifically, it is a dual-window irradiation device that uses an electron beam to irradiate textiles. Background Technology
[0002] In the electron accelerator manufacturing industry, it is well known that the irradiation devices used in electron accelerators to date are all single-window irradiation devices. These devices contain a scanning chamber with a titanium window attached to its lower end. When irradiating an object using this single-window device, the object must be in a natural environment, i.e., the atmosphere. However, for textiles, the purpose of electron beam irradiation is to complete the electron beam grafting process. Because this irradiation device is a single-window device with only one titanium window, the object must be in a natural environment, i.e., the atmosphere, for irradiation. In the atmosphere, due to the inhibitory effect of oxygen, the electron beam forms other substances, preventing the grafting conversion of the textile, resulting in a zero grafting conversion rate. Therefore, the aforementioned single-window irradiation device has limited functionality and cannot irradiate textiles. Summary of the Invention
[0003] The problem this invention aims to solve is to provide a dual-window irradiation device for textile irradiation. Using this dual-window irradiation device, the irradiation grafting process of textiles can be completed, improving the grafting conversion rate of the textiles.
[0004] The above-mentioned problems to be solved by the present invention are achieved by the following technical solutions: The present invention discloses a dual-window irradiation apparatus for textile irradiation, comprising a scanning box with an upper titanium window connected to its lower end. It is characterized by further including a connecting cover with a through-hole at its top, through which the upper part of the scanning box extends in a sealed manner. Below the upper titanium window is a support box, which is a cuboid with an open opening, its opening connected to a lower titanium window. Each of the long walls of the support box has corresponding flat holes arranged horizontally, and each of these holes contains a guide roller within the connecting cover on its outer side. On the outer sides of the two long walls of the connecting cover are a feeding roller and a winding roller, respectively, both parallel to and higher than the guide rollers. The outer end of the textile on the feeding roller passes sequentially through one flat hole in the support box, around the underside of the two guide rollers, through another flat hole in the support box, and then winds onto the winding roller. Both sides of the connecting cover between the upper and lower titanium windows have through-holes, each containing an upper nozzle and a lower nozzle facing the upper and lower titanium windows, respectively.
[0005] A further improvement of the present invention is that each of the four corners of one end wall of the support box has a nitrogen inlet, and each nitrogen inlet has a gas distribution pipe. The gas distribution pipe has gas outlet holes evenly distributed longitudinally, and one end of the gas distribution pipe is connected to a separately supplied nitrogen tank.
[0006] A further improvement of the present invention is that the bottom inner side of the support box has a water target, which includes a shell. The shell is a cuboid, with an inlet and an outlet machined on its side walls, and a circulating water channel is provided inside. The two ends of the circulating water channel are respectively connected to the inlet and the outlet.
[0007] A further improvement of the present invention is that a base is provided below the connecting cover. The base is box-shaped, being a cuboid, and its top length and width are adapted to the connecting cover, with the two connected together.
[0008] A further improvement of the present invention is that each of the four corners of the bottom of the base is connected to a roller.
[0009] A further improvement of the present invention includes two guide rails, with two rollers on the same side respectively placed in the corresponding guide rails in a rolling manner.
[0010] As can be seen from the above scheme, this invention, in addition to the upper titanium window, also includes a connecting cover. The top of the connecting cover has a through hole, and the upper part of the scanning box extends through the connecting cover in a sealed manner. Below the upper titanium window is a support box, which is a cuboid with an open opening, its opening connected to the lower titanium window. Each long wall of the support box has a corresponding flat hole, arranged horizontally, and each outer side of the connecting cover contains a guide roller. On the outer sides of the two long walls of the connecting cover are a feeding roller and a winding roller, both parallel to and higher than the guide rollers. The outer end of the textile on the feeding roller passes sequentially through one flat hole on the support box, around the underside of the two guide rollers, through another flat hole on the support box, and then winds onto the winding roller. Both sides of the connecting cover between the upper and lower titanium windows have through holes, each containing an upper nozzle and a lower nozzle facing the upper and lower titanium windows, respectively. Therefore, this invention includes both an upper and a lower titanium window. During operation, nitrogen is introduced into the connecting shroud and support box through nitrogen nozzles and gas distribution pipes within the four nitrogen inlets, eliminating air and thus preventing oxygen polymerization within these areas. During irradiation, the irradiated textile passes under the lower titanium window located within the support box, preventing the electron beam from forming other substances and hindering the grafting transformation of the textile. This enables the irradiation grafting process of the textile, solving the problem of the inability to irradiate textiles in the prior art. Attached Figure Description

Detailed Implementation
[0012] like Figure 1 , Figure 2 and Figure 3 As shown, the double-window irradiation device for textile irradiation of the present invention includes a scanning box 1 and a connecting cover 13. An upper titanium window is connected to the lower end of the scanning box 1. The upper titanium window includes an upper window frame 2, which is a rectangular frame whose size and shape are adapted to the lower end of the scanning box 1, and is sealed to the lower end of the scanning box 1. Below the upper window frame 2, a copper grid 3, an upper titanium foil 4, and an upper pressure frame 5 are connected in sequence.
[0013] The top of the connecting cover 13 has a through hole, through which the upper part of the scanning box 1 extends in a sealed manner above the connecting cover 13. A support box 11 is provided below the upper titanium window. This support box 11 is a cuboid with an open opening, its opening facing upwards and connected to the lower titanium window. The lower titanium window includes a lower window frame 8, a lower titanium foil 9, and a lower pressure frame 10. The lower window frame 8 is sealed on all four sides around the opening of the support box 11, and the lower titanium foil 9 is connected to the corresponding sides of the lower window frame 8 via the lower pressure frame 10 and screws 91.
[0014] The support box 11 has corresponding flat holes 19 machined on its two long walls. These flat holes 19 are horizontal, and guide rollers 14 are installed inside the connecting cover 13 on their outer sides. A cloth-feeding (or wrapping) roller 6 and a cloth-wrapping (or cloth-winding) roller 61 are respectively installed on the outer sides of the two long walls of the connecting cover 13. Both the cloth-feeding roller 6 and the cloth-wrapping roller 61 are parallel to and higher than the guide rollers 14. The outer end of the textile 20 on the cloth-feeding roller 6 passes through one flat hole 19 on the support box 11, around the lower side of the two guide rollers 14, passes through another flat hole 19 on the support box 11, and then wraps around the cloth-wrapping roller 61. Through holes are machined on both sides of the connecting cover 13 between the upper and lower titanium windows. An upper nozzle 23 and a lower nozzle 24, facing the upper and lower titanium windows respectively, are installed in the through holes. The upper nozzle 23 and the lower nozzle 24 are respectively connected to a separately supplied nitrogen tank via pipes.
[0015] See Figure 3 and Figure 5 To eliminate air within the support box 11 and maintain a nitrogen-protected environment, nitrogen inlets are machined at the four corners of one end wall of the support box 11. Two of these nitrogen inlets are located above and below the textile 20. Each of the four nitrogen inlets is equipped with a gas distribution pipe 18, which has longitudinally distributed air outlets 181, one end of which is connected to a separately supplied nitrogen cylinder.
[0016] See Figure 3 and Figure 4 To reduce the temperature inside the support box 11, a water target is provided on the inner bottom side of the support box 11. The water target includes a shell 16, which is a cuboid with an inlet 162 and an outlet 163 machined on its side wall, and a circulation channel 161 is provided inside. The two ends of the circulation channel 161 are connected to the inlet 162 and the outlet 163, respectively.
[0017] To facilitate the movement of the present invention, a base 15 is provided below the connecting cover 13. The base 15 is box-shaped, being a cuboid, with its top length and width adapted to the connecting cover 13 and the two connected together. Rollers 21 are attached to each of the four corners of the bottom. Two guide rails 22 are provided below the rollers 21, with the two rollers 21 on the same side respectively rolling within their respective guide rails 22.
[0018] During operation, nitrogen gas is introduced into the connecting cover 13 and the support box 11 through the upper nozzle 23, the lower nozzle 24, and the gas distribution pipes 18 within the four nitrogen inlets, respectively, eliminating air in the connecting cover 13 and the support box 11 and thus eliminating oxygen inhibition within them. During irradiation, the irradiated textile passes under the lower titanium window located within the support box 11, preventing the electron beam from forming other substances and hindering the grafting transformation of the textile. This achieves the irradiation grafting process for the textile, solving the problem of the inability to irradiate textiles in the prior art.
