Description

Technical Field

[0001] The present invention relates to the technical field of waste sorting, in particular to a radioactive solid waste sorting device and an operation method thereof. Background Art

[0002] With the development of China's nuclear industry and the gradual implementation of nuclear facility decommissioning work, the demand for radioactive waste treatment and disposal is increasing day by day. In particular, during the nuclear-related operations of relevant units such as nuclear fuel production and nuclear and radiation research, a certain amount of medium and low-level radioactive solid waste will be generated. Traditional methods for treating medium and low-level radioactive solid waste include incineration, wet oxidation, polymer solidification, cement solidification, and super compression. However, these methods have some common problems: large investment, high energy consumption, wide floor area, and require complex equipment and operating conditions.

[0003] For units that generate a certain amount of medium and low-level radioactive solid waste, since the amount of solid waste generated each year is relatively small, it is neither economical nor practical to establish an independent solid waste treatment facility. Therefore, they usually do not have the ability to treat this type of waste and can only choose to store it temporarily or rely on external services (transporting this type of waste to the waste treatment site). This results in a long treatment time for solid waste, making it inconvenient for later transportation and treatment, and the solid waste is in a flat state during sorting, making it inconvenient for feeding and sorting. Summary of the Invention

[0004] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments.

[0043] Embodiment 1

[0044] Refer to Figure 1 - Figure 2 , which is the first embodiment of the present invention. This embodiment provides a radioactive solid waste sorting device, including a glove access plate 200 through which the hand of the sorting personnel can reach into the interior of the box body 102 for sorting, and when sorting, wearing gloves can effectively reduce the impact of pollutants on the health of the sorting personnel.

[0045] Specifically, sorting members 100 are arranged in sequence along the conveying direction, and a glove access plate 200 is arranged on the sorting member 100. The glove access plate 200 is used to install sorting gloves. After the gloves are installed, the sorting personnel can sort through the gloves during sorting, which can effectively improve the safety of sorting.

[0046] Furthermore, the sorting member 100 includes a viewing window 101, which is connected to the glove access plate 200, and both the glove access plate 200 and the viewing window 101 are connected to the box body 102. The bottom end of the box body 102 is connected to the bracket;

[0047] The glove receptacle 200 is used for operators to wear gloves to sort radioactive solid waste. The glove receptacle 200 is connected to the viewing window 101 to ensure that the operator works in a safe environment. The viewing window 101 provides a transparent window that allows the operator to observe the inside of the box body 102 while maintaining a sealed environment to prevent the leakage of radioactive substances. The box body 102 is the core part of the entire sorting device, which is used to accommodate the radioactive solid waste to be processed, and realizes the safe treatment of the waste through the glove receptacle 200 and the viewing window 101. The bottom end of the box body is connected to the bracket to ensure the stability of the overall structure.

[0048] The lighting member 104 is installed at the top end of the box body 102.

[0049] Furthermore, the sorting member 100 further includes a conveyor belt 103. Figure 1 and Figure 3 An arrow indicating the conveying direction is provided on the conveyor belt 103 in [], and the conveyor belt 103 extends from the inner end of the box body 102 to the outside.

[0050] The lighting member 104 is installed at the top end inside the box body 102 to provide sufficient light, enabling the operator to clearly see the state of the waste for accurate operation. The conveyor belt 103 is located inside the box body 102 and extends to the outside, and is used to convey the radioactive solid waste to be sorted from the temporary storage area to the sorting area and transfer the sorted waste to the next processing step.

[0051] Embodiment 2

[0052] Referring to Figure 2 - Figure 5 , this is the second embodiment of the present invention. Different from the previous embodiment: a seal 300 is provided inside the sorting member 100. The seal 300 is used to seal the butt joint of the steel barrel. A docking device specifically for docking with the steel barrel is provided at the bottom end of the feeding port 308, and the seal 300 is used to maintain the airtightness inside the box body 102 to reduce gas leakage when not docked.

[0053] The seal 300 includes a cylinder 301 as a power source, and the piston rod is used to push the connecting rod to move; a first connecting rod 302, which is connected to the end of the piston rod of the cylinder 301. One end of the first connecting rod 302 away from the cylinder 301 is connected to a shaft rod 303, and one end of the shaft rod 303 is connected to the box body 102 through a fixing block 304.

[0054] Further, the seal 300 further includes a floating member 305, which is connected to the shaft 303 through a second link 306. The floating member 305 is connected to the shaft 303 through the second link 306 and can adapt to changes in different positions to ensure the sealing effect. The cover plate 307 is connected to the floating member 305 and is used to seal the feeding port 308 to prevent radioactive substances from leaking; the cover plate 307, which is connected to the floating member 305, and the cover plate 307 is used to seal the feeding port 308.

[0055] Embodiment 3

[0056] Refer to Figure 2 - Figure 6 , which is the third embodiment of the present invention. Different from the previous embodiment: the sealing degree between the cover plate 307 and the feeding port 308 is adjusted by the floating member 305.

[0057] Specifically, the sorting member 100 is provided with an inclined A surface and B and C ends in contact with the seal 300. Since the feeding port 308 is located on the A surface, when the cover plate 307 drives the lower movement through the link to seal the feeding port 308, the cover plate 307 first contacts the B end, and then the downward pressure thereof will cause the C end to tilt and move through the floating ball head 305a, so that the C end fits the feeding port 308.

[0058] Further, the floating member 305 includes a floating ball head 305a, which is used for the cover plate 307 to adapt to the deviation of the inclined A surface of the feeding port 308.

[0059] For example, when the feeding port 308 is to be sealed by the cover plate 307, first start the cylinder 301. The cylinder 301 drives the first link 302 to move. The moving first link 302 will drive the shaft 303 on the fixed block 304 to deflect. The deflected shaft 303 will drive the cover plate 307 on the second link 306 to press down. During the process of the cover plate 307 pressing down, the position where the cover plate 307 first contacts the feeding port 308 is the B end. The cylinder 301 continuously outputs a downward pressure, so that the cover plate 307 continues to press down. Since the cover plate 307 is floatingly connected to the second link 306 through the floating ball head 305a, the cover plate 307 can adapt to the deviation of the feeding port 308 and the A surface through the downward pressure.

[0060] Embodiment 4

[0061] Refer to Figure 1 - Figure 6 , which is the fourth embodiment of the present invention. Different from the above embodiments, this embodiment provides an operation method of a radioactive solid waste sorting device, including the above-mentioned radioactive solid waste sorting device, and converting the sorting device from the initial state to the preparation state;

[0062] Perform safe operations through the glove receptacle, observe the waste situation through the viewing window, and configure an exhaust duct at the rear of the box body 102, which is connected to the exhaust system for centralized treatment of waste gas;

[0063] Based on the waste situation, adjust the speed and direction of the conveyor belt to achieve the sorting and treatment of waste.

[0064] The operator observes the situation inside the box body 102 through the viewing window 101 to understand the specific shape, distribution, and type of the waste. The viewing window 101 is made of acrylic material to ensure clear observation while guaranteeing the safety of the operator. According to the observed waste situation, the operator adjusts the speed and direction of the conveyor belt 103 through the control cabinet to optimize the sorting process. If the waste volume is large or the types are complex, the conveyor belt speed can be appropriately reduced and the operation time can be increased to ensure that each type of waste can be accurately classified.

[0065] Example 5

[0066] Refer to Figure 1 - Figure 6 , which is the fifth embodiment of the present invention. Different from the above embodiments: the inside of the box body 102 is in a slightly negative pressure state, and the seal 300 is used for sealing docking with a 200L steel drum. Before the steel drum is successfully docked with the feeding port 308, the seal 300 always seals the feeding port 308. When the steel drum is docked with the feeding port 308, it is driven by the lifting member to move upward for docking.

[0067] Further, first convey the items to be sorted to the inside of the box body 102 through the conveyor belt 103, and then the sorting personnel sort the items through the gloves. The sorted items are manually put into the corresponding feeding port 308 and introduced into the steel drum through the feeding port 308.

[0068] Since the A surface is inclined, the material classification fails to hit the feeding port 308 and slides to the conveyor belt 103 under its own gravity.

[0069] When the sorting personnel are sorting, they will classify the items. Since the A surface is inclined, when the object is not put into the feeding port 308, the object directly slides down to the conveyor belt 103 by its own gravity for re-sorting, thereby effectively reducing the situation of incomplete sorting.

[0070] Further, the sorting member is mainly responsible for the classification and preliminary treatment of waste. The sorted waste is transported to the crushing module through the conveyor belt for crushing and compression.

[0071] Example 6

[0072] Refer to Figure 7, which is the sixth embodiment of the present invention. Different from the above embodiments, the driving of the cylinder 301 is changed to motor driving.

[0073] Among them, the motor drives the rack through the gear, and the moving rack drives the first connecting rod 302 to deflect around the shaft rod 303 to drive the second connecting rod 306 to deflect and open the cover plate 307. The change of the cylinder 301 to a motor can be selected according to actual needs.

[0074] Embodiment 7

[0075] Refer to Figure 8 , which is the seventh embodiment of the present invention. Different from the above embodiments, the driving of the cylinder 301 is changed to foot pedal driving.

[0076] When it is necessary to open the cover plate 307, step on the pedal. One end of the pedal is hinged to the box body 102, and the middle of the pedal near the bifurcated end of the box body 102 is hinged to the first connecting rod 302. Therefore, when the pedal is pressed down, it will drive the first connecting rod 302 to deflect and compress the telescopic spring at the same time. The deflected first connecting rod 302 will drive the second connecting rod 308 to deflect and drive the cover plate 307 to open. When the cover plate 307 needs to be closed, release the pedal, and the elastic force of the telescopic spring can effectively drive the cover plate 307 to seal the feeding port 308.

[0077] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limitations. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
