[0052] The embodiments of the present application provide a radiographic film drying device. The radiographic film drying device can effectively dry both sides of the detection film through the setting of the drying assembly, ensure the drying effect of each position of the detection film, and fix the film through the setting of the placing assembly during the drying process to prevent the film from being lifted by hot air and thus affect the drying efficiency of the film. The radiographic film drying device will be described in detail below. It should be noted that the description order of the following embodiments is not limited as the preferred order of the embodiments.

[0053] The present application will be described in detail below with reference to the drawings and specific embodiments. Embodiment 1

[0054] Please refer to Figures 1-14 The radiographic film drying device provided in the embodiments includes a box body 1, a plurality of placing plates 2 are arranged in the box body 1, a baffle 101 is arranged in the box body 1, a heating box 4 is arranged on one side of the baffle 101, and an air extraction box 3 is arranged on one side of the heating box 4; a drying assembly arranged in the box body 1 is used to dry the detection film on the placing plate 2; and a placing assembly arranged on the placing plate 2 is used to prevent and adsorb the detection film.

[0055] The setting of the drying assembly can effectively dry both sides of the detection film, avoid uneven drying of both sides of the detection film, and ensure the drying effect of each position of the detection film, thereby avoiding uneven drying of the detection film and deviation of the image displayed by the detection film.

[0056] Secondly, with the setting of the placing assembly, the negative pressure generated by the air extractor 302 can be used to adsorb and fix the film during the drying process, preventing the film from being lifted by the hot air and solving the adverse effects caused by the movement of the film during the drying process.

[0057] Next, the water vapor collected at the top of the box 1 can be guided and collected into the water collection tank 104 through the setting of the inclined block 102 and the drainage rod 103, avoiding the generation of water droplets on the inner wall of the top of the box 1 after a long time of contact with water vapor, and preventing the water droplets from falling onto the detection film, causing the detection film to dry and wet repeatedly. Moreover, the water vapor in the exhaust pipe 5 can be filtered and isolated through the setting of the filter screen 502, preventing the water vapor with chemical components from being discharged outside with the gas. Example 2

[0058] Referring to Figure 3 , Figure 5 , Figure 8 , Figure 9 and Figure 11 , on the basis of Example 1, the drying assembly comprises: a plurality of air extractors 302 installed inside the air extraction tank 3; a heater 401 installed at the top of the heating tank 4, and a plurality of electric heating tubes 402 in a serpentine structure connected to the bottom of the heater 401; a plurality of gas outlet pipes 404 connected to one side of the heating tank 4, one end of the gas outlet pipe 404 penetrating through the baffle 101 and extending below the placing plate 2; an air inlet pipe 301 provided on one side of the box 1 and in communication with the air extraction tank 3; a duct 304 provided on the opposite sides of the air extraction tank 3; and an air passage pipe 303 provided between the air extraction tank 3 and the heating tank 4.

[0059] After the X-ray detection film is developed, it needs to be dried. During the drying process, the film is placed in the placing groove 201, then the air extractor 302 and the air inlet pipe 301 are used to draw the air outside into the air extraction tank 3, and through the air passage pipe 303, the air is drawn into the heating tank 4. At the same time, the heater 401 is powered to heat the electric heating tubes 402, so that the electric heating tubes 402 can heat the air in the heating tank 4. Then, as the air continues to be injected into the heating tank 4, the heated air in the heating tank 4 is discharged into the outlet pipe 404 and then into the box 1, to dry the detection film inside the box 1.

[0060] Referring to Figure 8 and Figure 9 , a plurality of evenly distributed air outlet holes 405 are formed on the gas outlet pipe 404, and a dust screen is provided on the air inlet pipe 301. Through the setting of the plurality of gas outlet pipes 404 and the plurality of air outlet holes 405, the heated hot air can be uniformly discharged into each position inside the box 1, so that the overall temperature inside the box 1 rises, avoiding uneven temperature inside the box 1, which affects the drying effect of the detection film.

[0061] With reference to Figure 11 Further, on the basis of embodiment 2, the electric heating tube 402 is connected with the heat-conducting net 403 on both sides, the heat-conducting net 403 is made of copper material, since the copper has excellent heat-conducting property, and the heat-conducting net 403 is connected with the electric heating tube 402, so that the heat generated by the electric heating tube 402 can be well transferred to the heat-conducting net 403, and the contact area with the gas is increased through the heat-conducting net 403, and the heat-conducting range is improved, so as to ensure that the gas in the heating box 4 is rapidly heated. Embodiment 3

[0062] With reference to Figure 3 , Figure 4 , Figure 6 and Figure 7 On the basis of embodiment 1, the placing assembly comprises: a placing groove 201 opened on the surface of the placing plate 2; two adsorption plates 2021 arranged in the placing groove 201; a grid 202 arranged between the two adsorption plates 2021; a sliding block 203 connected to the opposite sides of the placing plate 2, a plurality of sliding grooves 2032 matched with the sliding block 203 are opened on the inner wall of the box 1, and one end of the sliding block 203 is located in the sliding groove 2032; a pressing hole 308 opened in the box 1 and communicated with the sliding groove 2032; and a pressing pipe 204 connected to one side of the two sliding blocks 203.

[0063] Before the detection film is dried, the placing plate 2 can be pulled out from the box 1, and the detection film is placed in the placing groove 201, at this time, the four corners of the detection film are located on the adsorption plate 2021, if the length of the placed detection film is much smaller than the length of the placing groove 201, then the two corners on the same side of the detection film are placed on the adsorption plate 2021, and through the arrangement of the grid 202, the hot air in the box 1 can dry the lower surface of the detection film during the drying process, so as to ensure that the two surfaces of the detection film are evenly dried, and avoid that the uneven drying of the two surfaces of the detection film leads to the deviation of the content displayed in the detection film, and finally affects the understanding and result of the staff reading the film.

[0064] After the placing is completed, the placing plate 2 is pushed into the box 1, and during the pushing process, the moving direction and moving distance of the placing plate 2 can be limited through the sliding block 203 and the sliding groove 2032. Embodiment 4

[0065] With reference to Figure 4 , Figure 8 and Figure 14On the basis of Embodiment 2 and Embodiment 3, the conduit 304 communicates with the pressing hole 308, and the pressing hole 308 corresponds to the position of the pressing pipe 204, the conduit 304 is provided with the blocking plate 307 matched with the pressing hole 308, and the conduit 304 is provided with the bracket 305, one side of the bracket 305 is connected with the reset spring 306 connected with the blocking plate 307.

[0066] Further, the adsorption plate 2021 is provided with the negative pressure pipe 2031, one end of the negative pressure pipe 2031 extends into the sliding block 203, the pressing pipe 204 communicates with the negative pressure pipe 2031, and the outer side of the pressing pipe 204 is provided with the air hole 2041 communicated with the pressing pipe 204.

[0067] Then, the suction fan 302 runs in the process of suction, the negative pressure is generated in the suction box 3, and the inside of the conduit 304 is affected, but the blocking plate 307 in the conduit 304 abuts against the pressing hole 308 under the action of the reset spring 306, so that the inside of the conduit 304 is in a sealed state, but when the placing plate 2 is pushed into the box body 1, the pressing pipe 204 on the sliding block 203 is inserted into the pressing hole 308, and the blocking plate 307 is pushed open, at this time, the negative pressure in the suction box 3 can act on the pressing pipe 204 through the conduit 304 and the pressing hole 308, so that the gas in the negative pressure pipe 2031 enters the suction box 3 through the air hole 2041 and the conduit 304 under the action of the pressure difference, and because the negative pressure is generated in the negative pressure pipe 2031, the detection negative film can be effectively adsorbed, so that the detection negative film is not blown up in the drying process, and the overall drying effect of the detection negative film is affected. Embodiment 5

[0068] Referring to Figure 10 and Figure 12 On the basis of Embodiment 1, the box body 1 is internally provided with a plurality of U-shaped exhaust pipes 5, the inner wall of the top of the box body 1 is provided with the inclined block 102, and the inclined block 102 is inclinedly arranged towards the exhaust pipe 5.

[0069] With the drying of the detection negative film, the moisture on the detection negative film is dried into water vapor, and rises to the position of the inclined block 102 along with the airflow, at this time, the gas is discharged to the exhaust pipe 5 along the inclined surface of the inclined block 102, and finally enters the exhaust pipe 5 and is discharged out of the box body 1.
