Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a device for harmless treatment of nuclear medicine waste. Background Art

[0002] The nuclear medicine waste harmless treatment device is a device specially used to treat radioactive waste generated by the nuclear medicine department. These wastes include solid waste, liquid waste and airborne waste, collectively referred to as "radioactive wastes".

[0003] The existing public patent (publication number CN114589190A) discloses "a nuclear medicine waste harmless treatment device, which includes a cylinder, a driving mechanism, a crushing mechanism, a control mechanism and a linkage mechanism; the inner wall of the upper end of the cylinder is fixedly connected to a fixed plate, and the inner wall of the cylinder at the lower end of the fixed plate is fixedly connected to a support plate, the fixed plate is semicircular, the support plate is circular, and a discharge hole is arranged on the support plate corresponding to the fixed plate; a sealing cover is arranged close to the upper part of the fixed plate; the driving mechanism is arranged on the fixed plate so as to be located at the center of the cylinder, the rotating shaft of the driving mechanism is fixedly connected to a rotating plate, the upper and lower ends of the rotating plate are slidably connected to the fixed plate and the support plate, and the left and right ends are slidably connected to the inner wall of the cylinder; the crushing mechanism, the control mechanism and the linkage mechanism are all arranged below the support plate, and the control mechanism is rotatably connected to the crushing mechanism through the linkage mechanism. The device has a crushing function, and can separate solids and liquids at the same time, thereby increasing the storage space and having good sealing performance."

[0004] In the above-mentioned compared patents, the linkage mechanism and the crushing mechanism are connected by rotation to realize the crushing function and can complete the solid-liquid separation. However, in the process of realizing the crushing function, the operator needs to manually control the reset according to the crushing status, which makes the operation steps cumbersome. In addition, during the feeding stage, monitoring must be carried out with the aid of a monitor. The function of the monitor is to control the drive mechanism to pause after each rotation to ensure that the drive mechanism isolates the waste at the lower end of the cylinder from the left side of the top of the support plate to prevent the radiation and odor of the waste from escaping to the outside when the sealing cover is opened. This operation only relies on the monitor to control the sealing protection function. Once the monitor fails, it is very likely to cause leakage of radiation and odor, thereby causing a major safety accident. Summary of the invention

[0012] Preferably, a pulverizing motor is fixedly provided at the front end of the protective shell near the pulverizing mechanism, the output end of the pulverizing motor is fixedly connected to the pulverizing roller, and the two pulverizing rollers are meshed and connected via two gears.

[0014] Preferably, the protective feeding mechanism includes an annular frame, a feeding frame is fixedly provided at the upper opening of the annular frame, a discharging frame is fixedly provided at the lower opening of the annular frame, a rotating shaft is rotatably provided inside the annular frame, a plurality of rotating baffles are fixedly provided on the rotating shaft body, and the other ends of the plurality of rotating baffles are slidably provided on the inner surface of the annular frame.

[0015] Preferably, a feeding motor is fixedly provided at the front end of the protective shell near the protective feeding mechanism, and the output end of the feeding motor is fixedly connected to the front end of the rotating shaft.

[0016] Preferably, a second liquid outlet valve is provided through the front end of the protective shell near the temporary storage box, and a protective door is hingedly provided at a lower position of the front end of the protective shell.

[0017] Working principle: When using this processing device, the staff first puts the waste into the inside from the feed port to start processing. During the processing, the waste will first enter between the two rotating partitions inside the protective feeding mechanism, and then the feeding motor drives the rotating shaft and the rotating partition to rotate, so that the material will be driven to rotate to the position of the discharge frame and enter the inside of the crushing processing mechanism. At the same time, during the movement of the material inside the protective feeding mechanism, the rotating partition will isolate the space between the feeding frame and the discharge frame in the annular frame, so that the waste entering the protective feeding mechanism will be immediately isolated;

[0018] Then the waste entering the crushing treatment mechanism will enter the interior of the crushing frame from the crushing port. At this time, the crushing motor is started to drive the crushing roller to rotate, so that the waste is crushed by the crushing roller. In the process of crushing, the liquid will be squeezed out and fall through the shaking filter screen into the interior of the liquid treatment mechanism. When the crushed solid falls on the upper end of the shaking filter screen, the elastic plate has elasticity, which will drive the shaking filter screen to shake under the action of gravity, thereby improving the effect of solid-liquid separation, and at the same time facilitating the solid to fall along the shaking filter screen to the upper end of the filter conveyor belt. When the solid waste moves to the filter conveyor belt, the conveyor belt motor is started to drive the filter conveyor belt to move the solid waste The waste moves to one side, and at the same time, the cylinder is started to drive the squeezing block to squeeze the solid waste, thereby squeezing the liquid in the fixed waste and causing it to fall, and squeezing the solid waste together. When the solid waste is squeezed too much, the cylinder will drive the fixed waste to move toward the squeezing plate when pushing, and drive the squeezing plate to overcome the pulling force of the return spring and start to move. After moving to the front end, the solid waste will slide down the inside of the moving frame due to gravity and enter the bottom position of the protective shell for storage. At this time, the first radiation detector can obtain whether the bottom of the protective shell is still radioactive, which is convenient for the staff to decide to open the protective door to take it out or store it to wait for the radioactivity to decay;

[0019] The separated liquid waste will fall into the temporary storage box. At this time, the radiation inside the temporary storage box will be detected again by the first radiation detector. If the radiation amount meets the standard, it can be directly discharged through the second liquid outlet valve. When the liquid radioactivity exceeds the standard, the output pump is started to pump the liquid waste into the storage box for attenuation. After waiting for attenuation and meeting the standard, it can be discharged through the first liquid outlet valve.

[0020] (III) Beneficial effects

[0021] The present invention provides a nuclear medicine waste harmless treatment device, which has the following beneficial effects:

[0022] 1. The present invention provides a harmless treatment device for nuclear medical waste. During the loading process of the device, the waste will first enter between the two rotating partitions inside the protective feeding mechanism, and then the feeding motor will drive the rotating shaft and the rotating partition to rotate, so that the material will be driven to rotate to the position of the discharge frame and enter the interior of the crushing treatment mechanism. At the same time, during the movement of the material inside the protective feeding mechanism, the rotating partition will isolate the space between the feeding frame and the discharge frame in the annular frame, so that the waste entering the protective feeding mechanism will be immediately isolated, which greatly realizes the safety of feeding and avoids the possibility of radiation and odor leakage.

[0023] 2. The present invention provides a harmless treatment device for nuclear medical waste. The device uses the rotation of a crushing roller to crush the waste. During the crushing process, the liquid is squeezed out and flows into the liquid treatment mechanism through a shaking filter. When the solid particles fall to the upper part of the shaking filter, due to the elastic characteristics of the elastic plate, the shaking filter vibrates under the action of gravity, thereby enhancing the solid-liquid separation efficiency and promoting the solid particles to fall along the shaking filter to the upper part of the filter conveyor belt. The movement of the solid waste on the conveyor belt is driven by the conveyor belt motor, and at the same time, the cylinder pushes the extrusion block to apply pressure to the solid waste to squeeze out the liquid therein and promote the aggregation of solid particles. When too much solid waste accumulates, the cylinder pushes the extrusion plate to overcome the resistance of the reset spring and move the extrusion plate to the front end. At this time, the solid waste slides down along the inside of the moving frame due to gravity and is finally stored at the bottom of the protective shell, which significantly improves the convenience of crushing treatment.

[0035] Specifically, in the above specific embodiment, the crushing and processing mechanism 1 equipped in the device can effectively crush the waste and simultaneously complete the solid-liquid separation during the crushing process, thereby simplifying the radioactive attenuation processing process. Subsequently, through the synergistic effect of the protective shell 202 and the liquid processing mechanism 3, the solid and liquid wastes are stored and attenuated respectively, which significantly improves the processing efficiency.

[0036] like Figure 3-6As shown, the crushing mechanism 1 includes a crushing frame 101, a filter conveyor belt 109 and a support base 111. A crushing port 103 is provided at the upper end of the crushing frame 101, and a discharge port 104 is provided on one side of the crushing frame 101 near the lower end. Two crushing rollers 102 are rotatably arranged inside the crushing frame 101, and a shaking filter screen 108 is rotatably arranged at a position near the discharge port 104 inside the crushing frame 101. An elastic plate 107 is fixedly arranged at the other end of the shaking filter screen 108, and the other end of the elastic plate 107 is fixedly connected to one side of the crushing frame 101. A cylinder 106 is fixedly arranged at the upper end of the support base 111, and an extrusion block 105 is fixedly arranged at the output end of the cylinder 106. The filter conveyor belt 109 is arranged inside the protective shell 202 near the discharge port 104, and a conveyor belt motor 209 is fixedly arranged at the rear end of the protective shell 202. The output end of the conveyor belt motor 209 is connected to the filter conveyor belt 109, and the front end of the protective shell 202 is close to the crushing mechanism 1 A crushing motor 204 is fixedly arranged at the position, the output end of the crushing motor 204 is fixedly connected to the crushing roller 102, the two crushing rollers 102 are meshed and connected by two gears, a second liquid outlet valve 207 is penetrated at the front end of the protective shell 202 near the temporary storage box 303, a protective door 208 is hingedly arranged at the lower position of the front end of the protective shell 202, a moving frame 206 is penetrated at the front end of the protective shell 202, two sliding rods 211 are slidably arranged at the front end of the moving frame 206, an extrusion plate 212 is fixedly arranged between the rear ends of the two sliding rods 211, a reset spring 210 is fixedly connected between the front ends of the two sliding rods 211 and the front end of the protective shell 202, a support base 111 is fixedly arranged at the rear end of the protective shell 202, a reinforcing frame 110 is fixedly arranged between the lower end of the support base 111 and the protective shell 202, and an extrusion block 105 is slidably arranged inside the protective shell 202 near the rear end of the extrusion plate 212;

[0037] Specifically, in the above specific embodiment, after the waste is introduced into the pulverizing treatment system, it will first pass through the pulverizing port 103 and enter the inner area of ​​the pulverizing frame 101. At this stage, the pulverizing motor 204 is activated to drive the pulverizing roller 102 to rotate. The rotation of the pulverizing roller 102 causes the waste to be pulverized into smaller particles. During the pulverizing process, the liquid component in the waste is squeezed out and falls through the pores of the filter screen and flows into the liquid treatment system. At the same time, the pulverized solid particles are deposited on the upper layer of the filter screen. The filter screen shakes under the action of the elastic plate 107. This shaking not only improves the efficiency of solid-liquid separation, but also promotes the solid particles to slide down along the filter screen and finally reach the upper end of the filter conveyor belt 109. After the solid waste reaches the filter conveyor belt 109, the conveyor belt motor 209 is started to push the solid waste to one side. At the same time, the cylinder 106 starts to work, exerting pressure on the solid waste, further squeezing out the liquid therein, and making the solid waste tightly gathered. If too much solid waste is accumulated, the cylinder 106 will push them toward the squeeze plate 212. After overcoming the pulling force of the return spring 210, the squeeze plate 212 starts to move until it reaches the frontmost position. At this time, the solid waste will slide down the inside of the moving frame 206 to the bottom of the protective shell 202 due to gravity and be stored there. In order to ensure safe operation, the first radiation detector 302 will detect whether there is any radioactive material left at the bottom of the protective shell 202. This detection result is crucial for the staff, as it determines whether the protective door 208 should be opened to take out the solid waste, or whether they should be stored until the radioactive material decays to a safe level.

[0038] like Figure 3-5 As shown, the liquid processing mechanism 3 includes a temporary storage box 303 and a storage box 301, one side of the temporary storage box 303 is fixedly arranged inside the protective shell 202 near the filter conveyor belt 109, a first radiation detector 302 is penetrated inside the temporary storage box 303, an output pump 304 is penetrated at the lower end of the temporary storage box 303, a transfer pipe 305 is fixedly arranged at the output end of the output pump 304, a liquid inlet 306 is opened at the upper rear end of the storage box 301, the other end of the transfer pipe 305 is fixedly connected to the position of the liquid inlet 306 at the rear end of the storage box 301, the storage box 301 is fixedly arranged inside the protective shell 202 near the upper end, a second radiation detector 307 is fixedly arranged on one side of the storage box 301, and a first liquid outlet valve 205 is penetrated on the side of the protective shell 202 close to the storage box 301;

[0039] Specifically, in the above specific embodiment, during the liquid waste treatment process, the liquid waste separated from the source will gradually settle in the temporary storage box 303. At this stage, in order to ensure the safety of treatment, the first radiation detector 302 is required to perform a detailed radiation level test on the liquid waste in the temporary storage box 303. If the test result shows that the radiation level has met the safety standard, the liquid waste can be directly discharged from the system through the second liquid outlet valve 207 to achieve safe treatment. On the contrary, if the test finds that the radioactivity of the liquid waste exceeds the established safety threshold, the system will immediately start the output pump 304. The function of the output pump 304 is to safely pump the liquid waste with excessive radioactivity into a special storage box 301. In the storage box 301, the liquid waste will undergo a natural attenuation process until its radioactivity level drops to a safe range. When the safety standard is met, the liquid waste that has been attenuated can be safely discharged from the system through the first liquid outlet valve 205, thereby completing the entire treatment process.

[0040] like Figure 7 As shown, the protective feeding mechanism 4 includes an annular frame 402, a feeding frame 401 is fixedly arranged at the upper opening of the annular frame 402, a discharging frame 405 is fixedly arranged at the lower opening of the annular frame 402, a rotating shaft 403 is rotatably arranged inside the annular frame 402, a plurality of rotating baffles 404 are fixedly arranged on the shaft body of the rotating shaft 403, and the other ends of the plurality of rotating baffles 404 are all slidably arranged on the inner surface of the annular frame 402, a feeding motor 203 is fixedly arranged at the front end of the protective housing 202 near the position of the protective feeding mechanism 4, and the output end of the feeding motor 203 is fixedly connected to the front end of the rotating shaft 403;

[0041] Specifically, in the above specific embodiment, in the waste treatment process, first, the waste will be introduced into the protective feeding mechanism 4, located between the two rotating partitions. Subsequently, the feeding motor 203 is started to drive the rotating shaft and the rotating partition to rotate in coordination. In this process, the material is transported to the position of the discharge frame 405 with the rotation movement, and finally enters the crushing processing mechanism 1. At the same time, during the movement of the material inside the protective feeding mechanism 4, the rotating partition effectively isolates the space between the feed frame 401 and the discharge frame 405 in the annular frame 402. This design ensures that the waste entering the protective feeding mechanism 4 can be isolated immediately, thereby ensuring the safety and efficiency of the treatment process.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
