Description

Technical Field

[0001] This utility model relates to the field of sampling and detection equipment technology, and in particular to a slice-type aerosol radiation dose rate automatic detector. Background Technology

[0002] In the field of radioactive aerosol sampling and detection, existing technical solutions involve directly storing the sampled filter membrane in the filter box without coating and thickness compression, resulting in a thickness exceeding the specifications of the aerosol filter membrane standard source.

[0003] For example, in the existing patent with authorization announcement number CN115494539B, the sampled filter membrane is placed in the filter box and then directly tested. Although this meets the testing requirements, it is no longer applicable to the increasingly stringent filter membrane specifications, so thickness pressing is required.

[0004] The traditional solution involves manually transporting the filter cartridges containing the filter membranes to the laboratory, where pressure equipment is used to press the stacked filter membranes into a shape that meets testing specifications. However, this process has the following drawbacks:

[0005] 1. If the filter membrane is pressed directly, the filter box needs to be placed manually, which is labor-intensive. Moreover, after the filter membrane is pressed by the pressure equipment, the pressure head often sticks to the filter membrane, requiring manual separation of the filter membrane and the pressure head, which reduces work efficiency and poses a significant radiation exposure hazard to operators and the environment.

[0006] 2. To prevent the pressure head from sticking to the filter membrane, the coating needs to be placed on the filter membrane before pressing. This requires manual placement of the coating on the filter membrane in each filter box to prevent it from sticking to the pressure head. This operation not only prolongs the sample processing cycle, but also significantly increases labor costs as the number of samples increases, and also increases the risk of radiation exposure for operators and the environment. Utility Model Content

[0035] After adopting the above technical solution, the beneficial effects of this utility model are:

[0036] The present application discloses a slice-type automatic aerosol radiation dose rate detector, which includes a frame on which a cutting and transporting device, a filter box storage device, and a detection device are mounted. The cutting and transporting device is used to cut a filter membrane containing aerosol into several uniformly shaped sliced ​​filter membranes and transport them. The filter box storage device holds several empty filter boxes, and the cutting and transporting device transports several sliced ​​filter membranes together and places them in the same empty filter box to form a sample to be coated. The detection device is used to detect the sliced ​​filter membranes. In this application, the cutting and transporting device, the filter box storage device, and the detection device are all known technologies for aerosol sampling and detection in the prior art. Their specific structures will not be described in detail here. The technical effect of their combination is that after the filter membrane is cut and placed in the filter box, the aerosol on the sliced ​​filter membrane is detected by the detection device.

[0037] This application includes a packaging device mounted on a frame.

Furthermore, it eliminates the need for manual placement, thus reducing labor costs. Simultaneously, the pressing mechanism reduces the overall thickness of the filter membrane, meeting the required filter membrane specifications. Attached Figure Description

[0057] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0058] like Figures 1 to 3 As shown, this utility model includes a frame 1, on which a slitting and transporting device 11, a filter box storage device 12, and a detection device 13 are mounted. The slitting and transporting device 11 is used to slit and transport a filter membrane containing aerosol (obscured in the figure) into several uniformly shaped slit filter membranes. The filter box storage device 12 stores several empty filter boxes 2, and the slitting and transporting device 11 transports several slit filter membranes and places them together in the same empty filter box 2 to form a sample to be coated. The detection device 13 is used to detect the slit filter membranes.

[0059] In this application, the slitting and conveying device 11, the filter cartridge storage device 12, and the detection device 13 are all well-known technologies in the prior art for aerosol sampling and detection. Their specific structures will not be described in detail here. The technical effect of their combination is that after the filter membrane is slited and placed in the filter cartridge, the aerosol on the slid filter membrane is detected by the detection device. Of course, the filter membrane here refers to the sampled filter membrane, which samples aerosols in the air through the sampling unit and is then slited and conveyed by the slitting and conveying device 11.

[0060] This application addresses the problems existing in the prior art by installing a packaging device 14 on the frame 1. The packaging device 14 is arranged between the filter box storage device 12 and the detection device 13 along the filter membrane detection path. The packaging device 14 is used to cover and press the slit filter membrane placed in the empty filter box 2 to form a packaged sample.

[0061] The encapsulation device 14 includes a film-coating feeding device 3 and a sample pressing device 4. The film-coating feeding device 3 holds several films 5, and the slitting and conveying device 11 transports at least one film 5 and places it on the sample to be coated to form a sample to be pressed. The film-coating feeding device 3 works in conjunction with the existing slitting and conveying device 11 to realize the automatic feeding of the film 5 and the action of placing it on the sample to be coated, replacing the traditional manual placement of the film 5, reducing labor costs and labor intensity, and preventing the pressing head from sticking to the filter membrane during subsequent pressing, thereby improving the pressing effect and work efficiency.

[0062] The sample pressing device 4 includes a pressing mechanism 41 and a slitting and conveying device 11. The sample to be pressed is transported to the pressing mechanism 41, where it is pressed to form a packaged sample. The slitting and conveying device 11 then transports the packaged sample to the testing device 13 for testing. When the pressing mechanism 41 presses the filter membrane with the coating 5, it can replace the traditional method of manually placing the filter box. The traditional slitting and conveying device 11 is sufficient for handling, eliminating the need to add other handling devices to the existing structure and reducing production costs. Furthermore, it replaces manual placement, reducing labor costs. At the same time, the overall thickness of the filter membrane is reduced after pressing by the pressing mechanism 41, meeting the filter membrane specification requirements.

[0063] like Figures 3 to 6 As shown, the film feeding device 3 includes a film feeding rack 31, which is located near the filter box storage device 12. The film feeding rack 31 holds a number of film sheets 5. When the cutting and conveying device 11 conveys the film sheets 5, it can transport at least one film sheet 5 from the film feeding rack 31 to the filter membrane for covering by means of suction, gripping or clamping.

[0064] The film supply rack 31 is provided with a film-containing area 311, which is used to hold the film 5.

[0065] A vertically arranged film supply power component 32 is installed on the film supply frame 31. Preferably, the film supply power component 32 is an electric cylinder. The film supply power component 32 is located outside the film covering area 311. The film supply power component 32 is driven to connect with the film supply support component 33. The film supply support component 33 is located below and adapted to the film covering area 311. The film supply support component 33 supports the film 5 located in the film covering area 311. The film supply power component 32 drives the film supply support component 33 to move vertically back and forth in the film covering area 311 to realize the automatic lifting of the film 5.

[0066] In this application, when the membrane 5 needs to be placed on the filter membrane, the membrane supply power unit 32 keeps the membrane 5 in a designated position through the membrane supply support assembly 33, making it easy for the slitting and conveying device 11 to grab the membrane 5. After grabbing, the membrane supply support assembly 33 is driven to rise, continuing to raise the membrane 5 to the designated position for the next grab. During this process, the membrane supply device 3 of this application cooperates with the slitting and conveying device 11 to automatically place the membrane 5 on the filter membrane, realizing automatic feeding of the membrane 5, improving work efficiency, and reducing labor costs; at the same time, it replaces the traditional operation method that requires manual placement of the membrane 5, improving detection accuracy and reducing radiation exposure risks.

[0067] In this application, the film supply frame 31 is provided with a power component mounting area, and the film supply power component 32 is mounted in the power component mounting area, which facilitates the installation of the film supply power component 32 on the film supply frame 31 without occupying external space and resulting in a compact structure. The power component mounting area is connected to the film covering area 311, and the drive end of the film supply power component 32 is positioned facing the film covering area 311 and extends into the film covering area 311. Its drive end can be connected to the film supply support assembly 33.

[0068] The film supply support assembly 33 is horizontally arranged and includes a film supply mounting plate 331, a film supply support plate 332, a plurality of support guides 333, and a plurality of support elastic members 334. The film supply mounting plate 331 is connected to the drive end of the film supply power member 32. The film supply support plate 332 is arranged parallel above the film supply mounting plate 331. The top end of the support guide 333 is connected to the film supply support plate 332. The support guide 333 is slidably arranged on the film supply mounting plate 331. The support elastic members 334 elastically abut against the film supply mounting plate 331 and the film supply support plate 332.

[0069] Under normal conditions, the film supply mounting plate 331 is controlled by the film supply power component 32. It is connected to the drive end of the film supply power component 32 and elastically supports the film supply support plate 332 through the support elastic component 334, so that the film supply support plate 332 is arranged parallel to the film supply mounting plate 331. The function of the supporting elastic element 334 between the film supply mounting plate 331 and the film supply support plate 332 is that, in order to ensure that at least one sheet of film 5 can be accurately picked up each time when the slitting and conveying device 11 picks up the film 5, the downward movement distance of the slitting and conveying device 11 is required to be greater than the distance of direct contact with the film 5, thus extending the downward movement path. Therefore, after the slitting and conveying device 11 touches the film 5, it must continue to move downward. In order to prevent damage to the film 5, the supporting elastic element 334 is used for support in the film supply support assembly of this application. Thus, when the slitting and conveying device 11 moves downward, the excessive downward movement distance is converted into the compression amount of the supporting elastic element 334. After it picks up the film 5 and moves upward, the supporting elastic element 334 drives the film 5 to move upward through the film supply support plate 332 and resets to its original position.

[0070] Preferably, the positions and quantities of the support guides 333 and the support elastic elements 334 are one-to-one, with four of each type, respectively arranged at each corner of the film supply mounting plate 331 and the film supply support plate 332. The support guides 333 are shoulder screws, and the support elastic elements 334 are support springs, with the support springs sleeved on the shoulder screws. Both the film supply mounting plate 331 and the film supply support plate 332 have weight-reducing holes to reduce their respective weight.

[0071] like Figure 3 , Figures 7 to 10As shown, the sample pressing device 4 includes a filter box translation mechanism 42, which carries the sample to be pressed and moves it into the pressing mechanism 41 for pressing or removal.

[0072] The filter cartridge translation mechanism 42 includes a translational force member 421 and a translational carrier plate 422 driven and connected thereto. The sample pressing device 4 includes a support assembly 43, and the translational carrier plate 422 is horizontally slidably disposed inside the support assembly 43. The pressing mechanism 41 includes a pressing power member 411 mounted on the support assembly 43 and a pressing head assembly 412 driven and connected thereto. The pressing power member 411 drives the pressing head assembly 412 to reciprocate vertically. The pressing head assembly 412 is located inside the support assembly 43 and disposed above the translational carrier plate 422.

[0073] The horizontal transfer carrier plate 422 is used to support the sample to be pressed and the sample to be packaged. The sample to be pressed refers to the sample formed after the filter membrane is placed and covered in the air filter box 2, and the sample to be packaged refers to the sample formed after being pressed. The horizontal transfer carrier plate 422 is driven by the horizontal moving force component 421 to move back and forth in the horizontal direction, which meets the position requirements for placement, pressing and picking, and replaces the manual method of placing it under the pressing head assembly 412 for pressing, thus reducing labor costs.

[0074] The pressure head assembly 412 includes a pressure head body 4121, which includes a pressing surface 4122. A plurality of ejection components 413 are mounted on the pressure head body 4121. The ejection components 413 are vertically arranged and elastically abut against the pressure head body 4121. The bottom end of the ejection components 413 can extend vertically out of or be flush with the pressing surface 4122.

[0075] When the sample to be pressed needs to be pressed, the pressing power component 411 drives the pressing head body 4121 to move vertically downward, causing the ejection component 413 to move downward simultaneously. The bottom end of the ejection component 413 first contacts the coating membrane 5 (the filter membrane and coating membrane 5 are not shown in the figure) and continues to press the ejection component 413 until the pressing head body 4121 contacts the coating membrane 5. Then, the pressing power component 411 continues to apply pressure, pressing the filter membrane through the pressing head component 412, reducing its overall height. The pressed filter membrane and coating membrane 5 are called the packaged sample. After pressing is completed, the pressing head body 4121 moves upward. At this time, the bottom end of the ejection component 413 extends out of the pressing surface 4122 under the action of elastic force to abut against the coating membrane 5, separating it from the pressing surface 4122 and preventing the coating membrane 5 from sticking to the pressing surface 4122. This eliminates the need for manual separation, reduces labor costs, and improves work efficiency.

[0076] The ejection assembly 413 includes an ejector rod 4131 and an ejection reset member 4132. The ejector rod 4131 vertically penetrates the pressure head body 4121, and the ejection reset member 4132 elastically abuts against the ejector rod 4131 and the pressure head body 4121. Preferably, the pressure head body 4121 is provided with a mounting cavity 4123, and the ejector rod 4131 is coaxially mounted in the mounting cavity 4123. The ejector rod 4131 includes a rod portion 4133 and an ejector head 4134 fixedly connected to its bottom end. The top end of the rod portion 4133 penetrates the mounting cavity 4123 and is connected to an adjusting nut 4135. The ejection reset member 4132 elastically abuts against the ejector head 4134 and the bottom of the mounting cavity 4123. Preferably, the ejection reset member 4132 is a spring, and the spring is sleeved on the rod portion 4133.

[0077] In this application, the translational carrier plate 422 is provided with a sample placement slot. The sample to be pressed is placed in the sample placement slot to prevent it from moving and to ensure the stability of the pressing process. It should be noted that... Figure 8 , Figure 9 and Figure 10 The image only shows filter box 2, and does not show the filter membrane and membrane 5 placed inside filter box 2, which does not mean that filter box 2 is empty.

[0078] In this application, the support assembly 43 includes a lower mounting base 431 and an upper mounting base 432; the lower mounting base 431 is provided with two parallel support blocks 4311, and a slide rail 4312 adapted to the translation plate 422 is formed between the two support blocks 4311, and the translation plate 422 slides back and forth in the slide rail 4312 in the horizontal direction; the pressing power member 411 is mounted on the upper mounting base 432, and the pressing head assembly 412 is located inside the upper mounting base 432.

[0079] Based on the above structure, the working principle of this application is described as follows.

[0080] The sampled filter membrane is part of the filter membrane roll and needs to be cut and transported to the air filter box 2 by the cutting and transporting device 11. It is transported after each cut until the entire sampling area on the filter membrane is cut and transported to the air filter box 2 to form a sample to be coated.

[0081] Next, the covering and coating action 5 is carried out. A sheet of coating 5 is transported by the cutting and conveying device 11 and placed on the sample to be coated, specifically, on the filter membrane, to form the sample to be pressed.

[0082] The pressing action is then performed. The sample to be pressed is transported to the placement position I by the slitting and transporting device 11, that is, placed on the translational carrier plate 422. The translational force component 421 drives the translational carrier plate 422 to move it to the area below the pressing head body 4121, that is, to the pressing position II. The pressing head body 4121 presses the sample to form a packaged sample. Then the translational carrier plate 422 moves back to the placement position I. Finally, the slitting and transporting device 11 transports the packaged sample to the testing device 13 for testing.

[0083] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
