Description

Technical Field

[0001] The present invention relates to the field of medical waste treatment, and in particular to a medical waste crushing treatment device and method. Background Art

[0002] Medical waste refers to waste that is generated during the medical service process and cannot be directly reused. Some medical waste is highly infectious or toxic. Such medical waste cannot be recycled and reused and needs to be landfilled or incinerated according to relevant requirements. Although some medical waste cannot be directly reused, it can be recycled and produced into new products after proper cleaning and disinfection. For example, waste such as plastic infusion bottles (bags) and plastic infusion tubes can be disinfected and then crushed to obtain plastic particles, which can be used again for injection molding into new products later.

[0003] At present, when crushing medical waste such as plastic infusion bottles (bags) and plastic infusion tubes, since this type of medical waste is relatively soft, it is mostly crushed by a shredder. However, since there is a lot of air in the plastic infusion bottles (bags), they are easy to bounce when subjected to force, resulting in less medical waste that can be crushed per unit time and low crushing efficiency.

When the medical waste is extruded, the material inlet sealing plate 11 is closed, and when the material is fed into the processing box 2, the material inlet sealing plate 11 is opened. A circulating cutting mechanism is provided on the top of the processing box 2, and the circulating cutting mechanism is used to shred the extruded medical waste. A first material box 24 located below the discharge port is fixedly installed on the top of the bottom plate 1.

[0044] In this embodiment, the cyclic cutting mechanism specifically includes a fixed frame 14, a connecting column 16, a cutter 18, a driven plate 19 and a second motor 20. The fixed frame 14 is fixedly installed on the top of the processing box 2, and a limit plate 15 is fixedly installed on the outer wall of one side of the fixed frame 14. The connecting column 16 penetrates and is slidably installed on the limit plate 15. A mounting plate 17 is fixedly installed on the bottom of the connecting column 16, and the cutter 18 is installed on the bottom of the mounting plate 17. In this embodiment, the cutter 18 is fixedly installed on the mounting plate 17 by bolts, and the driven plate 19 is fixedly installed on the top of the connecting column 16. In order to increase the stability of the driven plate 19, two auxiliary connecting columns are also fixedly installed between the mounting plate 17 and the driven plate 19.

A rotating arm 21 is fixedly installed on the output end of the machine 20, and a driving rod 22 is fixedly installed on the end of the rotating arm 21 away from the second motor 20. A long waist slide is opened in the driven plate 19, and the driving rod 22 is located in the long waist slide. A rotating sleeve 23 is rotatably sleeved on the driving rod 22, and the outer wall of the rotating sleeve 23 is in contact with the top inner wall and the bottom inner wall of the long waist slide. In the half circle of the rotating arm 21 rotating from top to bottom, the driven plate 19 will be driven to move downward through the driving rod 22, and then the cutter 18 will move downward to cut the medical waste, and in the half circle of the rotating arm 21 rotating from bottom to top, the driven plate 19 will be driven to move upward through the driving rod 22, and then the cutter 18 will be driven to move upward to reset the cutter 18. In this way, during the continuous rotation of the rotating arm 21, the cutter 18 will move up and down in a cycle to perform continuous cutting work.

[0045] In this embodiment, in order to increase the stability of the first sliding rods 5 and the lead screw 7 , the same connecting frame is fixedly mounted on one end of the four first sliding rods 5 and the lead screw 7 away from the processing box 2 .

[0046] In this embodiment:

[0047] In the initial state, the material port sealing plate 11 is in an open state, and the front baffle 9 is in a closed state;

[0048] When crushing medical waste such as plastic infusion bags (bottles) and infusion tubes, the medical waste is firstly put into the processing box 2 through the feeding hopper 3. Since the processing box 2 is inclined, the medical waste can automatically roll in the direction of the front baffle 9 under the action of gravity. However, due to the obstruction of the front baffle 9, the medical waste will not be thrown out from the discharge port. After a certain amount of medical waste is poured in, the output ends of the two second hydraulic cylinders 13 are started to retract. The two second hydraulic cylinders 13 drive the material port sealing plate 11 to move into the processing box 2 through the connecting long plate 12, thereby blocking the material inlet of the processing box 2. Then the first motor 8 is started to run, driving the internal thread sleeve 6 to rotate forward, and the forward rotating internal thread sleeve 6 rotates forward. The threaded sleeve 6 drives the lead screw 7 to move into the processing box 2. Driven by the lead screw 7, the extrusion plate 4 will gradually move toward the front baffle 9. Under the extrusion of the extrusion plate 4 and the front baffle 9, the air inside the medical waste such as the plastic infusion bag (bottle) and the infusion tube will be squeezed out, and as the extrusion plate 4 continues to squeeze, the medical waste will be squeezed more tightly. After completing one squeezing work, the first motor 8 is started to run, driving the internal threaded sleeve 6 to rotate in the opposite direction, so that the squeezing plate 4 is reset, and then the material port sealing plate 11 is opened, and then the medical waste is continuously put into the processing box 2. Thereafter, the material port sealing plate 11 is closed, and the medical waste is continuously squeezed. After several operations, the processing box 2 can be filled with compacted medical waste;

[0049] After completing the compaction of the above-mentioned medical waste, the output end of the first hydraulic cylinder 10 is first started to extend, driving the front baffle plate 9 to move out of the processing box 2 until the discharge port is fully opened, and then the first motor 8 is started to drive the lead screw 7 to move forward intermittently, and the lead screw 7 pushes the extrusion plate 4 to move accordingly. Driven by the extrusion plate 4, the compacted medical waste will be gradually pushed out of the discharge port. After starting the second motor 20, it will drive the rotating arm 21 to rotate cyclically. In the process of each rotation of the rotating arm 21, in the half circle of the rotating arm 21 rotating from top to bottom, the driven plate 19 will be driven to move downward through the driving rod 22. The driven plate 19 drives the mounting plate 17 to move downward through the connecting column 16, and then drives the cutter 18 to move downward, thereby cutting the medical waste that moves to the outside of the discharge port. During the half circle of the rotating arm 21 rotating from bottom to top, the driven plate 19 is driven to move upward through the driving rod 22, and then drives the cutter 18 to move upward, so that the cutter 18 is reset. During the continuous rotation of the rotating arm 21, the cutter 18 will move up and down in a cycle, cooperating with the intermittent movement of the medical waste to the outside of the discharge port. Therefore, the gradual shredding of the medical waste can be completed, and the shredded medical waste will fall into the first material box 24 under the action of gravity.

[0050] Compared with the related art, the medical waste crushing and processing device provided by the present invention has the following beneficial effects:

[0051] By setting up the structures such as the extrusion plate 4, the first sliding rod 5, the internal threaded sleeve 6, the screw 7, the first motor 8, the front baffle 9, the first hydraulic cylinder 10, the material port sealing plate 11, and the circulating cutting mechanism, when in use, by starting the first motor 8, the extrusion plate 4 can be driven to gradually approach the front baffle 9, so as to cooperate with the front baffle 9 to squeeze out the air in the medical waste such as the infusion bag (bottle) and the infusion tube, and finally compact the medical waste. After opening the front baffle 9, the compacted medical waste is intermittently pushed out, and the operation of the circulating cutting mechanism can be cooperated to complete the crushing and processing of the medical waste. Since the medical waste has been compacted in advance, the amount of medical waste shredded per unit time is greatly increased, which greatly improves the crushing and processing efficiency of the medical waste.

[0052] Second embodiment:

[0053] The second embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0054] Please refer to Figure 8-Figure 11 In the medical waste crushing and processing device provided in the present embodiment, a long cylinder 30 is fixedly installed on the outer wall of the processing box 2 on one side away from the first hydraulic cylinder 10, and the top end of the long cylinder 30 extends into the first material box 24. A spiral auger 31 is rotatably installed in the long cylinder 30, and the medical waste crushed in the first material box 24 is lifted upward by the spiral auger 31. A third motor 32 is fixedly installed on the top end of the long cylinder 30, and the top end of the spiral auger 31 is fixedly connected to the output end of the third motor 32. A discharge pipe 33 is fixedly installed on the outer wall of the long cylinder 30 and near the top end. The discharge pipe 33 is located above the feeding hopper 3. The lifted medical waste crushed materials are discharged into the feeding hopper 3 through the discharge pipe 33 and finally fall into the processing box 2. Subsequently, the crushed materials after the initial crushing can be compacted, and then secondary crushing can be performed, so that the medical waste can be crushed more thoroughly and the obtained plastic particles will be smaller.

[0055] In this embodiment, in order to facilitate the separate collection of partially completed secondary crushing, a second material box 25 is fixedly installed on the top of the bottom plate 1, and a material guide plate 26 is provided at the bottom of the processing box 2. Specifically, a first fixed plate 27 is fixedly installed at the bottom of the processing box 2, and two second slide bars 29 are installed through and on the sliding rod of the first fixed plate 27, and one end of the two second slide bars 29 is fixedly connected to the material guide plate 26. A third hydraulic cylinder 28 is fixedly installed on the first fixed plate 27, and the output end of the third hydraulic cylinder 28 is fixedly connected to the material guide plate 26. When the crushed material needs to be discharged into the second material box 25, the output end of the third hydraulic cylinder 28 is started to extend, and the material guide plate 26 is pushed out to the position as shown in the figure. Figure 8In the state shown, after the output shaft of the third hydraulic cylinder 28 is started to retract, the guide plate 26 can be completely pulled back to the bottom of the processing box 2.

[0056] In this embodiment:

[0057] After the primary crushing of medical waste is completed, if it is necessary to further perform secondary crushing on some of the medical waste fragments, the fragments can be lifted and discharged into the processing box 2, and then compacted and then crushed for the second time. The specific operation of the secondary crushing is: start the third motor 32 to run, the third motor 32 drives the spiral auger 31 to rotate, and the spiral auger 31 will transport the fragments in the first material box 24 upward during the rotation. After the material runs to the top position of the long cylinder 30, it will be discharged downward through the discharge pipe 33 under the action of thrust, and the discharged fragments fall into the feeding hopper 3. The material enters the processing box 2 under the action of the material, and then the crushed material is compacted. After compaction, the output end of the third hydraulic cylinder 28 is started to extend, and the third hydraulic cylinder 28 gradually pushes the guide plate 26 out from the bottom of the processing box 2 until the front end of the guide plate 26 moves to the top of the second material box 25, and then the front baffle 9 is opened, and then the compacted crushed material is intermittently pushed out, and the cutting and crushing process is performed again through the circulating cutting mechanism. After the secondary crushing, the medical waste crushed material particles will be smaller on average, and will be discharged into the second material box 25 through the guide plate 26, and separated from the larger particles of the remaining first material box 24.

[0058] By configuring the long cylinder 30, the spiral auger 31, the third motor 32 and the discharge pipe 33, the medical waste after the primary crushing can be lifted and discharged into the processing box 2. After compaction and cutting, the medical waste can be crushed for the second time, which is beneficial for the relevant users to obtain smaller plastic particles. The invention has the advantage of high applicability. By configuring the guide plate 26, the second material box 25, the third hydraulic cylinder 28 and other components, the crushed particles after the secondary crushing can be guided and discharged into the second material box 25, thereby being separated from the primary crushed plastic particles. The invention has the advantages of convenient and flexible use.

[0059] Third embodiment:

[0060] The third embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0061] Please refer to Figure 12-Figure 15In the medical waste crushing and processing device provided in this embodiment, the cutter 18 is installed in a quick and detachable manner. Specifically, a plurality of square sockets 1701 are provided on the mounting plate 17, and a plurality of mounting plugs 34 are fixedly installed on the top of the cutter 18. The plurality of mounting plugs 34 all penetrate the corresponding square sockets 1701 and are slidably connected to the inner walls of the corresponding square sockets 1701. The plurality of mounting plugs 34 all have circular sockets 3401. A second fixing plate 35 is fixedly installed on the top of the mounting plate 17. Multiple insertion rods 36 are penetrated and slidably installed, and the multiple insertion rods 36 all penetrate the corresponding circular sockets 3401 and are slidably connected to the inner walls of the corresponding circular sockets 3401. One end of the multiple insertion rods 36 is fixedly installed with the same connecting plate 37, and the multiple insertion rods 36 are all provided with retaining springs 38. One end of the multiple retaining springs 38 is fixedly connected to the second fixed plate 35, and the other end is fixedly connected to the connecting plate 37. A handle is fixedly installed on the outer wall of the connecting plate 37 away from the second fixed plate 35 to facilitate the operation of the connecting plate 37.

[0062] In this embodiment, two limit-resisting rods are fixedly mounted on the connecting plate 37 , and one end of the two limit-resisting rods away from the connecting plate 37 is fixedly connected to the second fixing plate 35 .

[0063] In this embodiment:

[0064] When the cutter 18 has been used for a long time or needs to be replaced for other reasons, the handle is used to pull the connecting plate 37 in a direction away from the second fixing plate 35, and the connecting plate 37 drives the multiple plug rods 36 to move, and the multiple plug rods 36 will eventually disengage from the corresponding circular sockets 3401, so that the multiple installation plug blocks 34 are no longer restricted, and then the cutter 18 can be taken out downward. When reinstalling a new cutter 18, the connecting plate 37 is first pulled in a direction away from the second fixing plate 35, and the connecting plate 37 drives the multiple plug rods 36 to move, so that the multiple plug rods 36 are completely moved to the multiple square sockets 1701. On one side, during this process, multiple retaining springs 38 will be stretched to store elastic potential energy, and then the multiple mounting plugs 34 on the top of the cutter 18 are aligned with the corresponding square sockets 1701 and inserted upward until the top of the cutter 18 contacts the bottom of the mounting plate 17. At this time, the multiple insertion rods 36 are axially aligned with the corresponding multiple circular sockets 3401. After loosening the connecting plate 37, the connecting plate 37 will automatically reset under the pull of the multiple retaining springs 38, and the multiple insertion rods 36 can be automatically inserted into the corresponding circular sockets 3401, thereby completing the installation of the new cutter 18.
