In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] like Figures 1 to 5As shown, a specific embodiment of the utility model provides a protective box with a dust removal system. In industrial production, when X-rays and other light rays act on products to process or detect the products, the protective box with a dust removal system can prevent the internal light from radiating out, thereby preventing the light from leaking out and endangering the health of the operator; and the protective box with a dust removal system has a dust removal function, which can remove dust from the environment inside the box 1, thereby preventing dust and other impurities from affecting the product processing results or detection results.

[0041] like Figures 1 to 3 As shown, in some embodiments, the protective box with a dust removal system includes a box body 1 and a dust removal system. The dust removal system includes a blowing filter device 2, an air inlet channel and a dust outlet 121. The blowing filter device 2 is arranged in the box body 1, and the inlet of the blowing filter device 2 is connected to the external environment; the air inlet channel is arranged in the box body 1, and the air inlet channel has a channel inlet and a channel outlet 3, the channel inlet is connected to the outlet of the blowing filter device 2, and the channel outlet 3 is connected to the interior of the box body 1, and a first shielding portion is arranged between the channel inlet and the channel outlet 3 to block the light emitted by the light source from radiating from the channel inlet; the dust outlet 121 is arranged in the box body 1, and a second shielding portion is arranged between the dust outlet 121 and the light source to block the light emitted by the light source from radiating from the dust outlet 121. In this embodiment, the blowing filter device 2 is a FFU (fan filter unit), which has both filtering and air supply functions, and can achieve the purpose of dust removal for the interior of the box body 1. The light source is an X-ray source. In other embodiments, the light source may also be an α-ray source or a β-ray source, but is not limited thereto.

[0042] A first shielding portion is provided between the channel entrance and the channel exit 3; the setting of the first shielding portion can prevent the light in the box body 1 from radiating to the outside of the box body 1 through the channel entrance, thereby avoiding damage to human health. The dust exhaust port 121 is provided in the box body 1, and a second shielding portion is provided between the dust exhaust port 121 and the light source in the direction of the line connecting the light source and the dust exhaust port 121. The setting of the second shielding portion can prevent the light in the box body 1 from radiating to the outside of the box body 1 through the dust exhaust port 121, thereby damaging human health. The blowing filter device 2 has the function of filtering gas, and blows the filtered gas into the interior of the box body 1. The gas flow in the box body 1 drives the dust inside the box body 1 to be discharged from the dust exhaust port 121, so that the protective box with a dust removal system can prevent light from leaking outward while also discharging dust in the box body 1, thereby improving the quality of the working environment in the box body 1, ensuring internal cleanliness, and thus ensuring the detection effect of the product.

[0043] like Figure 1As shown, the box body 1 includes a top plate 11, a bottom plate 12 and lateral support plates. In the present embodiment, the upper surface of the air filter device 2 is flush with the top plate 11 and is sealed with the top plate 11, ensuring that only the inlet of the air filter device 2 is connected to the external environment at the top of the box body 1 while ensuring aesthetics, so as to prevent light leakage. In other words, the top plate 11 is provided with a mounting hole, and the air filter device 2 is installed in the mounting hole. In the present embodiment, the support plates of the box body 1 are made of a composite plate composed of 8K mirror stainless steel and lead plate, which has the effect of being beautiful and easy to clean. In other embodiments, the material of the support plates of the box body 1 can also be carbon steel, but it is not limited to this.

[0044] Specifically, Figure 3 and Figure 4 As shown, the dust removal system includes an air duct plate, which is formed with a channel outlet 3; the first shielding portion includes a first protective member 5, which is disposed between the air blowing filter device 2 and the air duct plate, and is spaced from the air duct plate and the air blowing filter device 2, and covers the channel outlet 3. Preferably, in this embodiment, the projection area of ​​the first protective member 5 on the plane where the channel outlet 3 is located is larger than the area of ​​the channel outlet 3, so that the first protective member 5 can block as much light as possible from different angles.

[0045] Further, in order to achieve the purpose of guiding and draining the gas blown into the box body 1 by the blowing filter device 2, in the first direction Y, the channel outlet 3 is located in the middle of the box body 1, and the first protective member 5 is in an inverted V-shaped structure, and the first protective member 5 extends along the second direction X, and the second direction X is perpendicular to the first direction Y. The setting of the inverted V-shaped first protective member 5 enables the gas blown into the box body 1 by the blowing filter device 2 to be smoothly diverted to both sides along the inclined surface of the first protective member 5, and flow to the channel outlet 3 from both sides, so that the gas can flow into the box body 1 more evenly, which is conducive to improving the dust removal range and effect.

[0046] Preferably, in order to make the flow range of the gas in the box body 1 as large as possible to improve the dust removal range, the projections of the channel outlet 3 and the dust exhaust port 121 in the third direction Z are staggered.

[0047] The air duct plate includes a first air duct plate 41 and a second air duct plate 42. The first air duct plate 41 and the second air duct are arranged at intervals on two opposite inner walls of the box body 1 along the first direction Y, and a channel outlet 3 is formed between the first air duct plate 41 and the second air duct plate 42. In the second direction X, both ends of the first air duct plate 41, the second air duct plate 42 and the first protective member 5 extend to two opposite inner walls of the box body 1, and the first air duct plate 41, the second air duct plate 42 and the side wall of the box body 1 are surrounded to form an air inlet channel. The arrangement of the first air duct plate 41 and the second air duct plate 42 makes the channel outlet 3 simple to form and easy to install.

[0048] In order to reduce the vortex generated between the side wall of the box 1 and the air duct plate during the gas flow process, the first air duct plate 41 is inclined along the direction close to the second air duct plate 42 toward the direction away from the blowing filter device 2; the second air duct plate 42 is inclined along the direction close to the first air duct plate 41 toward the direction away from the blowing filter device 2.

[0049] Furthermore, under the premise that the size of the channel outlet 3 is fixed and the light cannot be radiated outside the box body 1, in order to increase the ventilation volume of the air inlet channel, the end of the first air duct plate 41 close to the second air duct plate 42 is connected to the first extension portion 411, and the end of the second air duct plate 42 close to the first air duct plate 41 is connected to the second extension portion 421. In the second direction X, the first extension portion 411 and the second extension portion 421 extend in the direction away from the corresponding first air duct plate 41 and the second air duct plate 42, respectively. In other words, Figure 6 As shown, under the premise that the position and size of the channel outlet 3 remain unchanged, and under the premise that the installation positions of the first air duct plate 41 and the second air duct plate 42 in the first direction Y remain unchanged, compared with the first air duct plate 41 and the second air duct plate 42 without the first extension portion 411 and the second extension portion 421 (i.e. Figure 6 As for the two parts shown by the dotted line in the middle, the setting of the first extension part 411 and the second extension part 421 can increase the inclination angle of the first air duct plate 41 and the second air duct plate 42, thereby increasing the distance between the first air duct plate 41 and the second air duct plate 42 and the first protective member 5, thereby increasing the ventilation area of ​​the air inlet channel, and thereby increasing the ventilation volume of the air inlet channel.

[0050] like Figure 2 and Figure 5 As shown, the second shielding portion includes a U-shaped plate 61, which is invertedly connected to the box wall of the box body 1 and covers the dust outlet 121. Specifically, the box body 1 has a bottom plate 12, the dust outlet 121 is arranged on the bottom plate 12, the U-shaped plate 61 is inverted on the bottom plate 12, and the two side plates of the U-shaped plate 61 are connected to the bottom plate 12, and the middle connecting plate of the U-shaped plate 61 covers the dust outlet 121. Preferably, in this embodiment, the projection area of ​​the middle connecting plate of the U-shaped plate 61 on the plane where the dust outlet 121 is located is larger than the area of ​​the dust outlet 121, so that the U-shaped plate 61 can block as much light as possible from different angles.

[0051] Further, the second shielding portion further includes a shielding plate 62, and the U-shaped plate 61 and the box wall of the box body 1 form a dust exhaust channel, and the two ends of the dust exhaust channel have two openings. The shielding plate 62 is arranged at the opening far away from the channel outlet 3, and is sealed and connected to the U-shaped plate 61. Specifically, the U-shaped plate 61 and the bottom plate 12 form a dust exhaust channel extending along the second direction X, and the two ends of the dust exhaust channel have two openings. The shielding plate 62 is arranged at the opening close to the side wall of the box body 1, and is sealed and connected to the three surfaces of the U-shaped plate 61. Since the channel outlet 3 and the dust exhaust port 121 are staggered, that is, the channel outlet 3 and the dust exhaust channel are staggered, the pressure at the outlet of the dust exhaust channel close to the channel outlet 3 is greater than the pressure at the outlet far away from the channel outlet 3. The gas in the box 1 drives the dust to flow from the opening with a higher pressure to the opening with a lower pressure, causing the dust to pass through the opening with a higher pressure and the opening with a lower pressure in turn, and finally flow into the interior of the box 1, so that the dust cannot be discharged from the dust outlet 121 below the U-shaped plate 61. The shielding plate 62 shields the opening at the end with a lower pressure, so that the dust can be discharged smoothly from the dust outlet 121.

[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
