Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and more specifically, to a medical radioactive waste treatment device and method. Background Art

[0002] Medical radioactive waste contains radionuclides with different activities (such as etc.). If not properly treated, it will cause long-term harm to human health and the ecological environment. In the treatment process of medical radioactive waste, the crushing link is a key pretreatment step. Its core goal is to reduce the volume of solid waste (such as glassware, plastic utensils, fabrics contaminated with radioactive substances) through mechanical crushing, so as to facilitate subsequent solidification, decay or landfill disposal.

[0003] Currently, when the crushing wheel shears and extrudes radioactive waste, some waste particles (such as dust, fibers, viscous substances) are easily adhered to the tooth grooves, annular grooves or outer cylindrical surfaces on the wheel body. These residual wastes continuously release radiation. If not removed in time, it may cause operators to directly contact the residual wastes when maintaining the equipment, resulting in external irradiation or internal irradiation, thus affecting the physical health of the operators. Although some devices try to use mechanical scrapers or simple spray systems for automatic cleaning, the scrapers can only clean the outer cylindrical surface and cannot reach deep into the tooth grooves or annular grooves, and are ineffective for fiber entanglements and viscous residues. The spray system may cause the diffusion of radioactive sewage inside the cavity, increasing the burden of subsequent sewage treatment and wasting a large amount of water resources. Summary of the Invention

[0006] Preferably, the cleaning wheel mechanism includes a circular frame body. Several arc-shaped sliding grooves are formed in the surface of one end of the circular frame body facing the crushing wheel. Several first arc-shaped cleaning blocks are connected to the surface of one end of the circular frame body facing the crushing wheel, and the circular frame body is fixedly connected to the rotating rod.

[0007] Preferably, one end of each first arc-shaped cleaning block facing the crushing wheel is connected to a second arc-shaped cleaning block. A third rotating rod is rotatably connected to the inner cavity of the circular frame body, and a tooth groove cleaning block is connected to the surface of the third rotating rod.

[0008] Preferably, the width of the first arc-shaped cleaning block is equal to the distance between the crushing wheels. The second arc-shaped cleaning block is fitted with the annular groove formed on the surface of the crushing wheel. The tooth groove cleaning block is fitted with the tooth groove on the surface of the crushing wheel. The tooth groove cleaning block is located outside through the arc-shaped sliding groove. The outer surface of the first arc-shaped cleaning block is in contact with the outer surface of the crushing wheel. When the tooth groove cleaning block is located on the low-end surface of the arc-shaped sliding groove, the tooth groove cleaning block will coincide with the tooth groove of the crushing wheel. When the tooth groove cleaning block is in contact with the top-end surface of the arc-shaped sliding groove, the tooth groove cleaning block will be in contact with the tooth groove of the next crushing wheel.

[0009] Preferably, the first cleaning mechanism includes a third driving motor. The output end of the third driving motor is connected to a first connecting block. One end of the first connecting block is connected to a cleaning roller, and a connecting groove is formed in one end of the first connecting block facing the cleaning roller.

[0010] Preferably, the two ends of the cleaning roller are connected with a second connecting block, and the outer surfaces of the two ends of the cleaning roller are connected with a second rectangular sliding block, the end of the second rectangular sliding block away from the third driving motor is connected with a second electric telescopic rod, the components of the second cleaning mechanism are the same as the components of the first cleaning mechanism, the second rectangular sliding block is rotatably connected to the cleaning roller, and when the second connecting block coincides with the connecting groove, the cleaning roller in the first cleaning mechanism will be located at the lower end of the tooth groove cleaning block, and the cleaning brush on the surface of the cleaning roller will contact the lower end surface of the tooth groove cleaning block, and the cleaning roller in the second cleaning mechanism will be located at the end of the tooth groove cleaning block facing the crushing wheel, and the cleaning brush on the surface of the cleaning roller will contact the end surface of the tooth groove cleaning block, and the second connecting block is in a separated state from the connecting groove in the initial state.

[0011] Preferably, a transverse sliding groove is opened in the inner cavity of the processing chamber, and the second rectangular sliding block in the first cleaning mechanism is installed in the inner cavity of the transverse sliding groove. A vertical sliding groove is opened in the inner cavity of the processing chamber, and the second rectangular sliding block in the second cleaning mechanism is installed in the inner cavity of the vertical sliding groove.

[0012] Preferably, a method for treating medical radioactive waste treatment equipment comprises the following steps: S1. First, the first drive motor and the second drive motor are started, and the first rotating rod and the second rotating rod are driven to rotate toward each other. At this time, the medical radioactive waste is put into the feed cavity through the feed port, and falls into the interlaced area of the two crushing wheels in the crushing assembly under the action of gravity, and the two crushing wheels are used to shear, squeeze and crush the radioactive waste, and the crushed waste particles fall into the discharge port and are discharged to the subsequent processing unit; S2. After the crushing operation is completed, the infrared imager installed on the inner wall of the processing chamber scans the surface of the crushing wheel to detect whether there is any solid waste residue. If residue is detected, the system automatically enters the cleaning program and starts the first electric telescopic rod in the wheel cleaning assembly, so that the first electric telescopic rod extends, pushes the first rectangular sliding block to move horizontally in the first rectangular sliding groove, and drives the wheel cleaning mechanism to approach the crushing wheel until the first arc-shaped cleaning block fits the outer surface of the crushing wheel, the second arc-shaped cleaning block is embedded in the annular groove on the surface of the crushing wheel, and the tooth groove cleaning block is stuck in the tooth groove of the crushing wheel through the arc-shaped sliding groove; S3, at this time, the crushing wheel continues to rotate, so that the first arc-shaped cleaning block scrapes off the block or flake residue on the outer surface of the crushing wheel, and the second arc-shaped cleaning block removes the winding and residue in the groove, and at the same time, the tooth groove cleaning block slides up and down along the arc-shaped sliding groove, penetrates into the tooth groove, and peels off the adhered dust or granular waste until the crushing wheel completes the cleaning operation; S4. After the cleaning wheel assembly completes the cleaning operation and returns to its original position, at this time, the vision camera installed in the inner cavity of the processing chamber detects whether there is any solid waste remaining on the first arc-shaped cleaning block and the tooth groove cleaning block. If any residue is detected, the first cleaning mechanism and the second cleaning mechanism will be activated, causing the second electric telescopic rod to extend and pushing the second rectangular sliding block to move within the horizontal sliding groove, so that the second connecting block of the cleaning roller is inserted into the connecting groove of the first connecting block to achieve mechanical coupling, and the brush on the surface of the cleaning roller contacts the surfaces of the tooth groove cleaning block and the first arc-shaped cleaning block; S5. Start the third drive motor to drive the cleaning roller to rotate at high speed. The brush on its surface contacts the lower surface of the tooth groove cleaning block and the lower surface of the first arc-shaped cleaning block, and uses centrifugal force and brush friction to remove the residual particles. Similarly, adjust the position through the second electric telescopic rod in the vertical sliding groove to make the cleaning roller close to one end of the tooth groove cleaning block facing the crushing wheel, clean the residue on its side, and the high-speed rotating cleaning roller generates centrifugal force to throw the peeled waste particles towards the bottom of the processing chamber and discharge them through the discharge port to avoid secondary adhesion. Thus, all operations are completed.

[0013] Compared with the prior art, the advantages of the present invention are as follows: 1. In the present invention, the cleaning wheel mechanism integrates the first arc-shaped cleaning block, the second arc-shaped cleaning block, and the tooth groove cleaning block, which respectively fit the outer circular surface, the annular groove, and the tooth groove of the crushing wheel. Thus, during the rotation of the crushing wheel, the surface of the crushing wheel is cleaned. Moreover, the second arc-shaped cleaning block fits precisely with the annular groove, which can effectively remove fiber entanglements. The tooth groove cleaning block slides up and down through the arc-shaped sliding groove and penetrates into the tooth groove to peel off dust or viscous residues, achieving a dead-angle-free cleaning. In this way, multi-dimensional residue peeling of the crushing wheel can be carried out to avoid the long-term adhesion and release of radiation by residual waste.

[0014] 2. In the present invention, the brush material on the surface of the cleaning roller is radiation-resistant and wear-resistant, and can penetrate into the fine gaps of the cleaning block. Combined with the mechanical coupling design, the second connecting block is docked with the connecting groove to achieve thorough cleaning of the cleaning wheel assembly itself. The centrifugal force generated by the high-speed rotation of the cleaning roller throws the residual particles on the surface of the cleaning wheel assembly towards the bottom of the processing chamber and discharges them through the discharge port, reducing the probability of secondary adhesion of the residual particles to the cleaning block or the inner wall of the chamber, and thus reducing the probability of "secondary pollution hotspots".

[0015] 3. In the present invention, through the design of the first arc-shaped cleaning block and the second arc-shaped cleaning block, during the rotation of the crushing wheel, the first arc-shaped cleaning block and the second arc-shaped cleaning block will leave the solid waste at the head end of the arc at the lower end of the cleaning block, and the solid waste will fall into the discharge port through the curvature of the surface of the crushing wheel. Moreover, the tooth groove cleaning block fits the tooth groove of the crushing wheel, so the whole is arc-shaped, and the dust or viscous residue peeled off from the inside of the tooth groove will fall into the discharge port along the arc, thereby effectively preventing the solid waste from adhering to the surface of the cleaning wheel assembly. At the same time, the residual particles on the surface of the cleaning wheel assembly are thrown off by the centrifugal force generated by the high-speed rotating cleaning roller to avoid secondary adhesion and improve the overall cleaning effect.

One end of each first rectangular sliding block 605 away from the crushing wheel 407 is connected to a first electric telescopic rod 606. A first rectangular sliding groove is opened in the inner cavity of the treatment cavity 1, and the first rectangular sliding block 605 and the rotating rod 610 are installed in the inner cavity of the first rectangular sliding groove. One end of the first electric telescopic rod 606 is fixed in the inner cavity of the treatment cavity 1.

[0019] Specifically, the cleaning wheel mechanism 601 integrates a first arc-shaped cleaning block 602, a second arc-shaped cleaning block 603, and a tooth groove cleaning block 609, which are respectively attached to the outer circular surface, annular groove and tooth groove of the crushing wheel 407. Thus, during the rotation of the crushing wheel 407, the surface of the crushing wheel is cleaned. The second arc-shaped cleaning block 603 fits precisely with the annular groove, which can effectively remove fiber entanglements. The tooth groove cleaning block 609 slides up and down through the arc-shaped sliding groove 604, penetrates into the tooth groove to peel off dust or viscous residues, realizing cleaning without dead angles. In this way, multi-dimensional residue peeling can be carried out on the crushing wheel 407, avoiding the long-term adhesion and radiation release of residual waste.

[0020] Please refer to Figure 5 and Figure 6, the cleaning wheel mechanism 601 includes a circular frame 607. A plurality of arc-shaped sliding grooves 604 are formed on one end surface of the circular frame 607 facing the crushing wheel 407. A plurality of first arc-shaped cleaning blocks 602 are connected to one end surface of the circular frame 607 facing the crushing wheel 407, and the circular frame 607 is fixedly connected to the rotating rod 610.

[0021] Please refer to Figure 5 and Figure 6 , one end of each first arc-shaped cleaning block 602 facing the crushing wheel 407 is connected to a second arc-shaped cleaning block 603. A third rotating rod 608 is rotatably connected in the inner cavity of the circular frame 607, and a tooth groove cleaning block 609 is connected to the surface of the third rotating rod 608.

[0022] Please refer to Figure 8 , the width of the first arc-shaped cleaning block 602 is equal to the distance between the crushing wheels 407. The second arc-shaped cleaning block 603 fits into the annular groove formed on the surface of the crushing wheel 407. The tooth groove cleaning block 609 fits into the tooth groove on the surface of the crushing wheel 407, and the tooth groove cleaning block 609 is located outside through the arc-shaped sliding groove 604. The outer surface of the first arc-shaped cleaning block 602 is in contact with the outer surface of the crushing wheel 407. When the tooth groove cleaning block 609 is located at the low end surface of the arc-shaped sliding groove 604, the tooth groove cleaning block 609 will coincide with the tooth groove of the crushing wheel 407. When the tooth groove cleaning block 609 is in contact with the top surface of the arc-shaped sliding groove 604, the tooth groove cleaning block 609 will be in contact with the tooth groove of the next crushing wheel 407.

[0023] Please refer to Figure 7 , the first cleaning mechanism 7 includes a third driving motor 701. The output end of the third driving motor 701 is connected to a first connecting block 702. One end of the first connecting block 702 is connected to a cleaning roller 704, and a connecting groove 703 is formed at one end of the first connecting block 702 facing the cleaning roller 704.

[0024] Please refer to Figure 7, both ends of the cleaning roller 704 are connected with second connecting blocks 707, and second rectangular sliding blocks 705 are connected to the outer surfaces of both ends of the cleaning roller 704. One end of the second rectangular sliding block 705 away from the third driving motor 701 is connected with a second electric telescopic rod 706. The components of the second cleaning mechanism 8 are the same as those of the first cleaning mechanism 7. The second rectangular sliding block 705 is rotatably connected to the cleaning roller 704. When the second connecting block 707 coincides with the connecting groove 703, the cleaning roller 704 in the first cleaning mechanism 7 will be located at the lower end of the tooth groove cleaning block 609, and the cleaning brush on the surface of the cleaning roller 704 will contact the lower end surface of the tooth groove cleaning block 609. And the cleaning roller 704 in the second cleaning mechanism 8 is located at one end of the tooth groove cleaning block 609 facing the crushing wheel 407, and the cleaning brush on the surface of the cleaning roller 704 will contact one end surface of the tooth groove cleaning block 609. The second connecting block 707 is initially in a separated state from the connecting groove 703.

[0025] Specifically, the brush material on the surface of the cleaning roller 704 is radiation-resistant and wear-resistant, and can deeply clean the fine gaps of the cleaning block. The mechanical coupling design is used to dock the second connecting block 707 with the connecting groove 703 to achieve the thorough cleaning of the cleaning wheel assembly itself. The centrifugal force generated by the high-speed rotation of the cleaning roller 704 throws the residual particles on the surface of the cleaning wheel assembly 6 towards the bottom of the processing cavity 1 and discharges them through the discharge port 9, reducing the probability of the residual particles adhering to the cleaning block or the inner wall of the cavity again, and thus reducing the probability of the "secondary pollution hot spot".

[0026] A transverse sliding groove is opened in the inner cavity of the processing cavity 1, and the second rectangular sliding block 705 in the first cleaning mechanism 7 is installed in the inner cavity of the transverse sliding groove.

The solid waste falls into the discharge port 9 through the arc on the surface of the crushing wheel 407. Moreover, the tooth groove cleaning block 609 fits the tooth groove of the crushing wheel 407 and is thus integrally arc-shaped, so that the dust or viscous residue peeled off inside the tooth groove will fall into the discharge port 9 along the arc, effectively avoiding the solid waste adhering to the surface of the cleaning wheel assembly 6. At the same time, the centrifugal force generated by the high-speed rotating cleaning roller throws off the residual particles on the surface of the cleaning wheel assembly, avoiding secondary adhesion and improving the overall cleaning effect.

[0028] A treatment method for a medical radioactive waste treatment device includes the following steps: S1. First, the first drive motor 402 and the second drive motor 406 are started, and the first rotating rod 401 and the second rotating rod 404 are driven to rotate toward each other. At this time, the medical radioactive waste is put into the feed chamber 5 through the feed port 2, and falls into the interlaced area of the two crushing wheels 407 in the crushing assembly 4 under the action of gravity, and the two crushing wheels 407 are allowed to shear, squeeze and crush the radioactive waste, and the crushed waste particles will fall into the discharge port 9 and be discharged to the subsequent processing unit, and the rotation of the first drive motor 402 is stopped; S2. After the crushing operation is completed, the infrared imager installed on the inner wall of the processing chamber 1 scans the surface of the crushing wheel 407 to detect whether there is any solid waste residue. If residue is detected, the system automatically enters the cleaning program and starts the first electric telescopic rod 606 in the wheel cleaning assembly 6, so that the first electric telescopic rod 606 is extended, pushing the first rectangular sliding block 605 to move horizontally in the first rectangular sliding groove, driving the wheel cleaning mechanism 601 to approach the crushing wheel 407, until the first arc cleaning block 602 fits the outer surface of the crushing wheel 407, the second arc cleaning block 603 is embedded in the annular groove on the surface of the crushing wheel 407, and the tooth groove cleaning block 609 is stuck in the tooth groove of the crushing wheel 407 through the arc sliding groove 604; S3, at this time, restart the first driving motor 402 and let the crushing wheel 407 continue to rotate, so that the first arc-shaped cleaning block 602 can scrape off the block or flake residue on the outer surface of the crushing wheel 407, and the second arc-shaped cleaning block 603 can remove the winding and residue in the groove, and at the same time, the tooth groove cleaning block 609 can slide up and down along the arc-shaped sliding groove 604, penetrate into the tooth groove, and peel off the adhered dust or granular waste until the crushing wheel 407 completes the cleaning operation; S4. When the wheel cleaning assembly 6 completes the wheel cleaning operation, it will return to its original position. At this time, the visual camera installed in the inner cavity of the processing chamber 1 detects whether there is any solid waste remaining in the first arc-shaped cleaning block 602 and the tooth groove cleaning block 609. If any solid waste is detected, the first cleaning mechanism 7 and the second cleaning mechanism 8 will be activated, so that the second electric telescopic rod 706 is extended, and the second rectangular sliding block 705 is pushed to move in the horizontal sliding groove, so that the second connecting block 707 of the cleaning roller 704 is embedded in the connecting groove 703 of the first connecting block 702, so as to realize mechanical coupling, and the brush on the surface of the cleaning roller 704 is in contact with the surface of the tooth groove cleaning block 609 and the first arc-shaped cleaning block 602; S5. Start the third driving motor 701 to drive the cleaning roller 704 to rotate at high speed. The brush on its surface contacts the lower end surface of the tooth groove cleaning block 609 and the lower end surface of the first arc-shaped cleaning block 602, and uses centrifugal force and brush friction to remove residual particles. Similarly, adjust the position of the second electric telescopic rod 706 in the vertical sliding groove so that the cleaning roller 704 is close to the end of the tooth groove cleaning block 609 facing the crushing wheel 407 to clean the residue on its side. The high-speed rotating cleaning roller 704 generates centrifugal force to throw the stripped waste particles to the bottom of the processing chamber 1 and discharge them through the discharge port 9 to avoid secondary adhesion. All operations are terminated at this point.

A medical radioactive waste treatment device according to claim 6, characterized in that: A transverse sliding groove is provided in the inner cavity of the processing chamber (1), and the second rectangular sliding block (705) in the first cleaning mechanism (7) is installed in the inner cavity of the transverse sliding groove. A vertical sliding groove is provided in the inner cavity of the processing chamber (1), and the second rectangular sliding block (705) in the second cleaning mechanism (8) is installed in the inner cavity of the vertical sliding groove.

8. A treatment method for a medical radioactive waste treatment device, according to a medical radioactive waste treatment device as claimed in claim 7, characterized in that, The following steps are involved: S1. First, the first drive motor (402) and the second drive motor (406) are started, and the first rotating rod (401) and the second rotating rod (404) are driven to rotate towards each other. At this time, the medical radioactive waste is fed into the feed chamber (5) through the feed port (2), and falls into the interlaced area of the two crushing wheels (407) in the crushing assembly (4) under the action of gravity. The two crushing wheels (407) shear and squeeze the radioactive waste, and the crushed waste particles fall into the discharge port (9) and are discharged to the subsequent processing unit; S2. After the crushing operation is completed, an infrared imager installed on the inner wall of the processing chamber (1) scans the surface of the crushing wheel (407) to detect whether there is any solid waste residue. If any residue is detected, the system automatically enters the cleaning program and starts the first electric telescopic rod (606) in the wheel cleaning assembly (6), so that the first electric telescopic rod (606) is extended, pushing the first rectangular sliding block (605) to move horizontally in the first rectangular sliding groove, driving the wheel cleaning mechanism (601) to approach the crushing wheel (407), until the first arc-shaped cleaning block (602) fits the outer surface of the crushing wheel (407), the second arc-shaped cleaning block (603) is embedded in the annular groove on the surface of the crushing wheel (407), and the tooth groove cleaning block (609) is inserted into the tooth groove of the crushing wheel (407) through the arc-shaped sliding groove (604); S3, at this time, the crushing wheel (407) continues to rotate, so that the first arc-shaped cleaning block (602) scrapes off the block or flake residue on the outer cylindrical surface of the crushing wheel (407), and the second arc-shaped cleaning block (603) removes the entangled objects and residues in the groove, and at the same time, the tooth groove cleaning block (609) slides up and down along the arc-shaped sliding groove (604), penetrates into the tooth groove, and peels off the adhered dust or granular waste, until the crushing wheel (407) completes the cleaning operation; S4. After the cleaning wheel assembly (6) completes the cleaning wheel operation and returns to its original position, at this time, the vision camera installed in the inner cavity of the processing cavity (1) detects whether there is any solid waste remaining on the first arc-shaped cleaning block 602 and the tooth groove cleaning block 609. If any remaining waste is detected, the first cleaning mechanism (7) and the second cleaning mechanism (8) will be activated. As a result, the second electric telescopic rod (706) extends and pushes the second rectangular sliding block (705) to move within the horizontal sliding groove, causing the second connecting block (707) of the cleaning roller (704) to be inserted into the connecting groove (703) of the first connecting block (702), achieving mechanical coupling, and making the brush on the surface of the cleaning roller (704) contact the surfaces of the tooth groove cleaning block (609) and the first arc-shaped cleaning block (602). S5. Start the third drive motor (701) to drive the cleaning roller (704) to rotate at high speed. The brush on its surface contacts the lower surface of the tooth groove cleaning block (609) and the lower surface of the first arc-shaped cleaning block (602), and uses centrifugal force and brush friction to remove the remaining particles. Similarly, adjust the position through the second electric telescopic rod (706) in the vertical sliding groove, so that the cleaning roller (704) is close to one end of the tooth groove cleaning block (609) facing the crushing wheel (407) to clean the remaining waste on its side. Moreover, the high-speed rotating cleaning roller (704) generates centrifugal force, throwing the peeled waste particles towards the bottom of the processing cavity (1) and discharging them through the discharge port (9) to avoid secondary adhesion, thus ending all operations.
