Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of radioactive waste treatment, and particularly relates to a radioactive waste sorting box. Background Art
[0002] The basic principle of radioactive waste management is to collect, store, treat and dispose of waste in categories. Wastes with different radiation doses should be packaged and transported at different levels, and monitored and supervised according to different requirements. When workers enter a radioactive environment for maintenance operations, they need to wear labor protection supplies to ensure personal safety. These used labor protection supplies become radioactive waste. For low-radioactive waste such as waste labor protection supplies with a contact dose rate ≤ 2 mSv / h, usually, after manually sorting out the metal substances in the sorting box, the waste is sent to a gasification furnace for gasification and volume reduction treatment. These metal substances are mainly metal impurities mixed in during the recycling and transportation of waste labor protection supplies, as well as mechanical parts such as remaining screws forgotten in the protection supplies after maintenance operations. However, the current manual sorting process of radioactive waste sorting boxes is time-consuming and laborious, and the sorting work efficiency is low. Therefore, it is necessary to design a more efficient radioactive waste sorting box. Content of the Utility Model
[0003] Aiming at the above technical problems, the utility model provides a radioactive waste sorting box that reduces the amount of manual sorting operations and makes the sorting work more efficient.
[0004] To solve the above technical problems, the technical solution of the utility model is: a radioactive waste sorting box, including a box body. Feed inlets and discharge outlets are respectively arranged on both sides of the box body. A feed conveyor belt and a discharge conveyor belt are respectively arranged through the feed inlet and the discharge outlet. A vibrating conveyor plate and a roller conveyor are successively arranged between the feed conveyor belt and the discharge conveyor belt. A vibrating motor is fixedly connected to the lower end of the vibrating conveyor plate. A support platform is fixedly connected inside the box body below the vibrating conveyor plate. The vibrating conveyor plate is connected to the support platform through a spring. One side of the roller conveyor is fixedly connected to the side of the support platform. A metal collection box is arranged inside the box body below the roller conveyor and the discharge conveyor belt. A transparent observation window is installed on the side of the box body above the discharge conveyor belt. Two protective glove interfaces are arranged on the transparent observation window.
[0005] Further, the vibrating conveyor plate is inclined downward toward the side close to the roller conveyor, and a plurality of circular protrusions are fixedly connected to the upper surface of the vibrating conveyor plate.
[0006] Further, a metal detector is fixedly connected to the inner wall of the box above the discharge conveyor belt. A warning light and a controller are fixedly connected to the outside of the box. The metal detector is communicatively connected to the controller, and the warning light is controlled by the controller.
[0007] Further, an air outlet duct is fixedly connected to the upper end of the box, and an induced draft fan is installed on the air outlet duct.
[0008] The utility model has the following advantages compared with the prior art:
[0009] 1. By providing a vibrating conveyor plate and a roller conveyor in the utility model, the vibrating conveyor plate can vibrate and disperse the radioactive waste thereon, so that some of the metal objects wrapped in the radioactive waste are separated from the radioactive waste. The separated metal objects roll down along the inclined vibrating conveyor plate onto the roller conveyor and fall into the metal collection box through the gap between the two conveyor rollers of the roller conveyor, realizing the preliminary separation of the metal objects in the radioactive waste. Then, manual sorting is carried out after the preliminary separation, which can reduce the time consumed by manual sorting work and improve the work efficiency.
[0010] 2. By installing a metal detector before the manual sorting process in the utility model, and installing a controller and a warning light that match the metal detector. When the metal detector 12 detects that a metal is approaching, it sends an electrical signal to the controller 14. The controller 14 that receives the signal controls the warning light 13 to flash, reminding the sorting staff to pay attention to the metal objects in the radioactive waste passing through the sorting, further improving the accuracy of the sorting work results.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] The following will further illustrate the utility model in conjunction with the drawings.
[0016] Such asFigures 1 to 3 A radioactive waste sorting box as shown includes a box body 1. Feed ports and discharge ports are respectively provided on both sides of the box body 1. A feed conveyor belt 2 and a discharge conveyor belt 3 are respectively arranged in the feed port and the discharge port. Sealing covers are installed on the outer peripheries of the feed conveyor belt 2 and the discharge conveyor belt 3, and the sealing covers are fixedly connected to the box body 1 to prevent gas from leaking outside the sealing covers and the box body 1. Between the feed conveyor belt 2 and the discharge conveyor belt 3, a vibrating conveying plate 4 and a roller conveyor 5 are successively arranged. The vibrating conveying plate 4 is designed in a trapezoidal shape, with the short side close to the roller conveyor 5, and side platforms are installed on the other three sides to prevent the waste on the plate from falling from the other three sides. A vibrating motor 6 is fixedly connected to the lower end of the vibrating conveying plate 4. A support platform 7 is fixedly connected inside the box body 1 below the vibrating conveying plate 4. The vibrating conveying plate 4 is connected to the support platform 7 through a spring. One side of the roller conveyor 5 is fixedly connected to the side of the support platform 7. The gap width between adjacent conveying rollers of the roller conveyor 5 is set to 15 mm. The lower shell opening of the roller conveyor 5 forms a funnel shape, which can divert the metal substances falling from the gaps between the conveying rollers into a metal collection box 8. A metal collection box 8 is arranged inside the box body 1 below the roller conveyor 5 and the discharge conveyor belt 3. The metal collection box 8 is placed inside the box body 1, and a box door for taking out and replacing the metal collection box 8 is hinged on the outer wall of the box body 1. A transparent observation window 9 is installed on the side of the box body 1 above the discharge conveyor belt 3, and two protective glove interfaces 10 are provided on the transparent observation window 9.
[0017] In order to continuously convey the radioactive waste on the vibrating conveying plate 4 to the roller conveyor 5 under the action of jittering and throwing, the vibrating conveying plate 4 is inclined downward towards the side close to the roller conveyor 5. In order to prevent the radioactive waste on the inclined vibrating conveying plate 4 from falling into the roller conveyor 5 too quickly, resulting in insufficient vibration, a number of circular protrusions 41 are fixedly connected to the upper surface of the vibrating conveying plate 4.
[0018] In order to remind the sorting staff that the passing radioactive waste contains metal and further improve the accuracy of the sorting work results, a metal detector 12 is fixedly connected to the inner wall of the box body 1 above the discharge conveyor belt 3. A warning lamp 13 and a controller 14 are fixedly connected to the outside of the box body 1. The metal detector 12 is communicatively connected to the controller 14, and the warning lamp 13 is controlled by the controller 14. When the metal detector 12 detects the approach of metal, it sends an electrical signal to the controller 14, and the controller 14 that receives the signal controls the warning lamp 13 to flash to remind the sorting staff.
[0019] In order to form a negative pressure inside the box body 1, avoid the gas in the box body 1 from escaping to the outside of the box body 1, and at the same time collect and process the gas that may carry radioactive substances uniformly, an air outlet pipe 15 is fixedly connected to the upper end of the box body 1. An induced draft fan 11 is installed on the air outlet pipe 15 and is connected to the gas filtration and adsorption pipeline of the factory area.
[0020] The specific working process of the present utility model is as follows:
[0021] The low-level radioactive waste to be sorted is conveyed to the vibrating conveyor plate 4 through the feeding conveyor belt 2. The vibrating conveyor plate 4 vibrates continuously driven by the vibrating motor 6 and drives the radioactive waste on the vibrating conveyor plate 4 to shake. The radioactive waste is shaken loose while sliding down, and some of the metal items wrapped in the radioactive waste are separated from the radioactive waste, and roll down to the roller conveyor 5 along the inclined vibrating conveyor plate 4 and fall into the metal collection box 8 through the gap between the two conveyor rollers of the roller conveyor 5. The radioactive waste finally slides down to the roller conveyor 5 and is transported to the discharging conveyor belt 3. When these preliminarily separated radioactive wastes pass through the metal detector 12, if there are residual metal items, they will be detected by the metal detector 12 and an electrical signal will be sent to the controller 14. The controller 14 that receives the signal controls the warning lamp 13 to flash to remind the sorting staff. When the sorting staff works, they put their hands into the protective gloves connected to the protective glove interface 10 reserved on the box body 1 and complete the manual sorting work through the protective gloves. The radioactive waste after manual sorting is conveyed to the gasification furnace through the discharging conveyor belt 3 to complete the volume reduction treatment.
