[0024] X-rays have high energy and can ionize gas molecules or dust particles to form charged particles (positive and negative ions). X-ray ionization can be combined with electrostatic precipitators to enhance the capture ability of tiny particles (such as PM2.5), thereby improving dust removal efficiency.

[0025] Since X-rays are ionizing radiation, they are penetrating and biohazardous, so a shielding protection structure is needed to shield the X-ray source.

[0026] The existing shielding protection structure has the problem of being inconvenient to assemble due to its complicated structure.

[0027] The invention provides an X-ray source shielding protection structure.

[0028] See also Figure 1In one embodiment of the present invention, the X-ray source shielding protection structure includes: a first shell 100 and a ray tube 200, a high-voltage package 300, and a control board 400 installed in the first shell 100, wherein the ray tube 200 is used to emit X-rays, the high-voltage package 300 generates high voltage boost, and the control board 400 connects the high-voltage package 300 and the ray tube 200 through wires to achieve control. The high-voltage package 300 is responsible for converting the input low voltage into a high voltage, which is provided to the ray tube 200 to accelerate the electron beam and adjust the energy of the electron beam. The ray tube 200 emits X-rays. Further, in some embodiments, a shielding coating is provided on the outside of the first shell 100, wherein the shielding coating can be made of barium sulfate. Specifically, the first shell 100 includes a mounting frame 140, a first side plate 110, a second side plate 120, and a first mounting tube 130. It should be noted that disassembling the first shell 100 into independent modules can facilitate the installation of the ray tube 200, the high-voltage package 300, and the control board 400. Specifically, the mounting frame 140 is used for installing the high-voltage package 300. The mounting frame 140 is arranged in the first mounting cylinder 130 and is detachably connected to the first mounting cylinder 130. It should be noted that during the installation process, the high-voltage package 300 is first installed on the mounting frame 140, and then the mounting frame 140 and the high-voltage package 300 are loaded into the first mounting cylinder 130 together, and then the mounting frame 140 and the first mounting cylinder 130 are connected. Furthermore, the mounting frame 140 and the first mounting cylinder 130 can be connected by screw locking. Further, the first side panel 110 and the second side panel 120 are detachably mounted on both ends of the first mounting tube 130, respectively; wherein the ray tube 200 is arranged in the first mounting tube 130 and mounted on the first side panel 110, and the emitting end 210 of the ray tube 200 is exposed on the first side panel 110; wherein the control panel 400 is arranged in the first mounting tube 130 and mounted on the second side panel 120, and the connecting portion 410 of the control panel 400 is exposed on the second side panel 120. It should be noted that if the ray tube 200 or the control panel 400 fails, it is only necessary to remove the corresponding side panel for repair without disassembling the entire shell, thereby reducing downtime, and the exposed connecting portion 410 of the control panel 400 can support quick plugging and unplugging, thereby preventing internal cables from being damaged due to frequent disassembly and assembly. Furthermore, during assembly, the ray tube 200 and the control board 400 can be respectively installed on the corresponding side panels, and then the side panels can be connected to the first installation tube 130, so as to achieve the purpose of convenient assembly, thereby solving the technical problems existing in the prior art. Furthermore, in some embodiments, a detachable shielding cover can be added at the interface between the ray tube 200 transmitting end 210 and the control board 400 to further improve the protection redundancy, wherein the shielding cover is assembled on the structure when not in use.

[0029] In one embodiment, reference Figure 1The first side plate 110 and the second side plate 120 are fixed to the two ends of the first mounting tube 130 by screw locking; the mounting frame 140 is fixed to the first mounting tube 130 by screw locking, which can improve the connection stability between the first side plate 110, the second side plate 120 and the first mounting tube 130. Similarly, the same is true for the mounting frame 140, that is, the overall stability of the shielding structure is improved.

[0030] In one embodiment, both ends of the first installation tube 130 are provided with annular grooves (not shown in the figure), and the first side plate 110 and the second side plate 120 are provided with protrusions of annular structures (not shown in the figure), and the protrusions are plugged into the annular grooves. Under the action of the annular grooves and the protrusions, a pre-positioning effect can be formed between the first side plate 110, the second side plate 120 and the first installation tube 130. Further, in some embodiments, the first side plate 110 and the second side plate 120 can be made of lead material. At the same time, since the first side plate 110 and the second side plate 120 are shielding materials, the protrusions are also shielding materials. When the protrusions are inserted into the annular grooves, while achieving the effect of pre-positioning, they can also achieve a secondary shielding effect on the connection between the first side plate 110, the second side plate 120 and the first installation tube 130, thereby reducing the possibility of X-ray leakage from the connection between the first side plate 110, the second side plate 120 and the first installation tube 130.

[0031] In one embodiment, reference Figures 2 to 7The X-ray source shielding protection structure also includes a second shell 500 and an air supply assembly 600 installed on the second shell 500; the second shell 500 includes a second mounting tube 520 with an opening at one end, and the opening of the second mounting tube 520 is detachably connected to a third side plate 510, the first shell 100 is installed on the second mounting tube 520, and a first air duct 700 is formed between the inner walls of the first shell 100 and the second mounting tube 520. It should be noted that a gap is formed between the first shell 100 and the second mounting tube 520. In the present embodiment, this gap is the first air duct 700, and the inlet and outlet of the first air duct 700 are both opened in the second mounting tube 520, the air supply assembly 600 is connected to the inlet of the first air duct 700, and the first shell 100 and the second mounting tube 520 are detachably connected; the second mounting tube 520 is provided with a first through hole 521, and the first through hole 521 is used for allowing the wiring harness to pass through the second mounting tube 520 is connected to the connecting portion 410 of the control board 400, the third side plate 510 is provided with a second through hole 631, and the second through hole 631 is arranged corresponding to the emitting end 210 of the ray tube 200; the shielding coating is arranged on the inner wall of the second shell 500. Further, in this embodiment, the first shell 100 can be made of a material with good thermal conductivity, such as aluminum. Since the first shell 100 is arranged in the second shell 500, and a first air duct 700 is formed between the first shell 100 and the inner wall of the second shell 500, the air supply component 600 can send wind into the first air duct 700 through the inlet of the first air duct 700, and then flow out from the outlet of the first air duct 700. Under the flow of gas, the heat outside the first shell 100 can be taken away, thereby achieving a heat dissipation effect, and the first air duct 700 is designed to make the air flow only flow between the first shell 100 and the second shell 500, so as to prevent dust from entering the first shell 100 and affecting the life of the ray tube 200 and the control board 400. At the same time, the first housing 100 is detachably connected to the second housing 500. After the first housing 100, the high-voltage package 300, the transmitting tube, and the control board 400 are assembled, they are installed in the second housing 500. Since the third side plate 510 is detachably connected to the second housing 500, when the ray tube 200 needs to be inspected, only the third side plate 510 is removed to expose the transmitting end 210 without disassembling the entire second housing 500.

[0032] In one embodiment, reference Figure 7 The inner and outer walls of the first mounting tube 130 are provided with heat dissipation grooves 131. The heat dissipation grooves 131 can increase the surface area of ​​the first shell 100 and induce turbulence to improve the heat dissipation efficiency. It should be noted that one end of the heat dissipation groove 131 is close to the inlet of the airway, and the other end is close to the outlet of the airway.

[0033] In one embodiment, reference Figure 5 , the first through hole 521 and the connection portion 410 of the control board 400 are arranged in a staggered manner. If the first through hole 521 is aligned with the connection portion 410 of the control board 400, a high-frequency signal line (such as a clock line, a radio frequency line) may form a radiation antenna through the through hole, resulting in electromagnetic leakage. The staggered arrangement can reduce this problem.

[0034] In one embodiment, reference Figure 6 The third side plate 510 is against the first side plate 110, so that the gap between the first side plate 110 and the third side plate 510 can be reduced. The gap between the two side plates is reduced, which can reduce the possibility of radiation leakage from the gap between the shells, especially for scattered rays near the emission end 210 of the ray tube 200.

[0035] In one embodiment, the shielding coating is barium sulfate. It should be noted that this can reduce the weight of the second shell 500. Specifically, if the second shell 500 uses lead material to achieve the shielding effect, the weight of the second shell 500 will be heavier. In this case, the second shell 500 can use a lightweight material with a barium sulfate shielding coating to reduce the weight of the second shell 500, that is, to make the product lightweight. In some embodiments, the shielding coating can also be formed on the second shell 500 by spraying.

[0036] In one embodiment, reference Figure 6 The inlet of the first air duct 700 is arranged close to the first side plate 110 , and the outlet of the first air duct 700 is arranged at an end of the second mounting tube 520 opposite to the third side plate 510 .

[0037] Further, refer to Figure 2 , Figure 3 , Figure 4In some embodiments, the air supply assembly 600 includes an air supply fan (not shown), a first diverter 610, a first air supply duct 620, and a second diverter 630. The first air supply duct 620 connects the first diverter 610 and the second diverter 630, wherein the first air supply duct 620 and the first diverter 610 and the second diverter 630 can be connected by plugging and fixing. Specifically, the first air supply duct 620 is plugged with the first diverter 610 and the second diverter 630. After the plugging is completed, the first air supply duct 620 can be fixed to the first diverter 610 and the second diverter 630 by screw locking. Of course, in order to improve the shielding effect of the air supply assembly 600, the first diverter 610, the first air supply duct 620, and the second diverter 630 can be made of lead-containing material, or a barium sulfate coating can be provided on their surface. Further, the air supply fan is connected to the first diverter 610 and can deliver airflow to the first diverter 610. Further, there are multiple first air supply pipelines 620 and second diverters 630, and the first air supply pipelines 620 and the second diverters 630 correspond one to one. The air duct inlet 710 is also set to multiple groups, and each group of air duct inlets 710 is set to multiple. One group of air duct inlets 710 corresponds to one second diverter 630. Multiple second through holes 631 are opened on the second diverter 630, and the number of a group of air duct inlets 710 is also multiple. The second through holes 631 are set one to one with the air duct inlet 710. Further, the air duct inlet 710 is inclined. The inclined setting of the air duct inlet 710 can make most of the airflow entering the air duct through the air duct inlet 710 have a tendency to flow toward the air duct outlet 720. A flow channel 632 with an arc-shaped cross-section is set in the second diverter 630, and the flow channel 632 with an arc-shaped cross-section can reduce the resistance of the airflow during reversing. Furthermore, in order to achieve a better alignment effect between the outlet and the airway inlet 710 , the second shell 500 is configured as a rectangular structure, and further, four airway outlets 720 are configured.

[0038] In one embodiment, reference Figure 6 A first guide portion 522 is provided at the corner of the inner wall of the second mounting tube 520. The first guide portion 522 is used to reduce the flow resistance of the airflow at the corner and improve the heat dissipation effect.

[0039] In one embodiment, reference Figure 6The first shell 100 and the second mounting cylinder 520 are connected by screw locking. It should be noted that, in order to facilitate installation, a support column 523 is provided inside the second mounting cylinder 520, and the first shell 100 is against the support column 523. At this time, the screw connects the support column 523 and the first shell 100. Further, the second mounting cylinder 520 and the support column 523 can be integrally formed. Furthermore, a guide protrusion 524 is also provided on the inner wall of the second mounting cylinder 520. The function of the guide protrusion 524 is, on the one hand, to enable the first shell 100 and the support column 523 to be pre-aligned, and on the other hand, to enable the airway between the outer side of the first shell 100 and the inner wall of the second mounting cylinder 520 to be evenly distributed, that is, the gap distribution is even, so that the heat dissipation is more uniform.
