Description

Technical Field

[0001] The utility model relates to the technical field related to disinfection treatment, and in particular to a pre-crushing vertical medical waste disinfection treatment device. Background Art

[0002] Pre-crushing vertical medical waste disinfection and sterilization units are a type of sterilization and disinfection device widely used worldwide. Their disinfection processes typically include single-use high-temperature steam sterilization, single-use microwave sterilization, or a combination of high-temperature steam and microwave sterilization. Because these units utilize a pressure vessel as the sterilization container, the entire disinfection process (including the pre-crushing process) is enclosed, minimizing waste emissions. However, they also suffer from the disadvantage that medical waste can easily form bridges within the feed chamber, often preventing all waste from entering the crusher for crushing. Furthermore, when this occurs, the quick-opening door of the feed chamber is usually closed, and the crushing process has already begun. The air inside is filled with medical waste debris and high concentrations of pathogens. To prevent the release of airborne pathogens, the feed chamber cannot be opened directly for manual intervention. Consequently, once material bridging occurs, there is no effective solution.

[0003] At present, the mainstream emergency solution is the mechanical intervention solution, that is, installing a stirring device in the feed chamber to break the bridging, but the effect is not good, and the stirring device is easily damaged due to the entanglement of the material. In patent US20160318030A1, a technical solution to solve the bridging problem by pressing the material from the top is proposed. Specifically, a pressing plate and a scissor-type cross rod are installed on the inner side of the top of the quick-opening door of the pressure vessel feed chamber. When not working, the pressing plate and the scissor-type cross rod can be completely retracted into the feed chamber cover above the equipment, which will not affect the opening of the feed chamber door and normal feeding; when working, the driving device pushes the scissor-type cross rod on the top, and the expansion / folding of the scissor-type cross rod drives the pressing plate connected to the lower part of the scissor-type cross rod to move up and down, thereby pressing the medical waste to the crusher for crushing. In this patent, it is taken into account that once the debris generated during the crushing process of the crusher enters the space between the pressing plate and the inner side of the top quick-opening door, it will accumulate to a certain extent and affect the operation of the scissor-type cross rod. Therefore, the pressure plate and the inner wall of the feed chamber are sealed. However, after a period of use, the pressure mechanism will experience a sharp increase in the resistance between the airtight seal and the inner wall of the pressure vessel due to corrosion, wear, and adhesion of material debris, affecting normal operation. This pressure device also has the problem of a relatively complex structure and difficult maintenance.

[0004] CN220551917U discloses a material pressing device with a multi-stage telescopic material pressing assembly. It proposes a method for installing a material pressing mechanism on a vertical container. Specifically, the material pressing mechanism is installed in the feed chamber, and a multi-stage telescopic drive mechanism (oil cylinder, air cylinder, or electric cylinder) is connected through the top. The reciprocating motion of the drive mechanism drives the material pressing plate up and down to break the bridging. However, due to the long working stroke and high installation height, there are requirements for the height of the equipment workshop. At the same time, if the top cover is a movable flip structure, the flip radius of the drive mechanism is large during flipping, which limits its use in various applications. Furthermore, after a period of operation, the multi-stage telescopic rod is prone to increased resistance to closing due to debris adhesion, resulting in an increased failure rate.

[0005] The conventional and mature crusher pressing mechanisms in other industries are mostly not suitable for installation in pressure vessels, especially those used for medical waste disinfection and sterilization, which have strong internal corrosiveness and cannot meet the high pressure vessel sealing requirements. Or, due to their large size, they cannot be integrated and installed in the pressure vessels of small and medium-sized medical waste disinfection and treatment devices. Therefore, for pre-crushing vertical medical waste disinfection and treatment devices, bacterial medical waste will form bridges in the feed chamber, affecting the entry of medical waste into the crushing process, resulting in a series of problems such as difficulty in operating the process and lack of safe and reliable emergency solutions. Everyone is looking for a reliable solution that can reliably solve the problem of medical waste bridging in the feed chamber and ensure that medical waste can smoothly enter the crushing process.

[0007] The utility model provides a pre-crushing vertical medical waste disinfection and treatment device, which includes a disinfection pressure vessel, a crusher, a lateral pressing mechanism and a control system.

[0027] The technical solution of the present utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example 1:

[0029] like Figure 1-Figure 2 As shown, a pre-crushing vertical medical waste disinfection treatment device in this embodiment includes a disinfection pressure vessel 1, a crusher 2, a lateral pressing mechanism 3 and a control system 4. The lateral pressing mechanism 3 includes a pressing plate 21 and a driving component connected to the pressing plate 21. The crusher 2 and the pressing plate 21 are both arranged in the disinfection pressure vessel 1; the control system 4 is used to control the working state of the driving component so that the driving component drives the pressing plate 21 to move toward the crusher 2 or toward the inner wall of the disinfection pressure vessel 1.

[0030] The initial position of the pressing plate 21 is that the pressing plate 21 is close to the inner wall of the sterilization pressure vessel 1. When the material accumulates above the crusher 2 to form a material bridge, the driving component drives the pressing plate 21 toward the crusher 2, which can destroy the material bridge above the crusher 2 and promote the normal entry of the material into the crusher 2 for crushing. After the pressing is completed, the driving component can automatically drive the pressing plate 21 back to the initial position close to the inner wall of the feed chamber 11, which will not affect the feeding of medical waste from the feed port to the feed chamber 11.

[0031] The lateral pressing mechanism 3 is arranged on the side wall of the sterilization pressure vessel 1. The lateral pressing mechanism 3 is not connected to the feed quick-opening door 13 and does not occupy the space above the feed quick-opening door 13. When the feed quick-opening door 13 is opened, the lateral pressing mechanism 3 will not occupy the space around the feed quick-opening door 13, which has great advantages in installation height and layout difficulty.

[0032] The pre-crushing vertical medical waste disinfection treatment device in this embodiment can be a device that uses high-temperature steam disinfection, a device that uses microwave disinfection, or a device that uses high-temperature steam and microwave coordinated disinfection.

[0033] In this embodiment, the disinfection pressure vessel 1 includes a feed cabin 11 located above the crusher 2 and a disinfection and sterilization cabin 12 located below the crusher 2. The feed cabin 11 is provided with a feed quick-opening door 13, and the disinfection and sterilization cabin 12 is provided with a discharge quick-opening door 14. The pressing plate 21 is located in the feed cabin 11 between the feed quick-opening door 13 and the crusher 2.

[0034] The quick-opening feeding door 13 is provided at the feeding port of the feeding chamber 11. When the quick-opening feeding door 13 is opened, medical waste can be fed into the feeding chamber 11 from the feeding port. When the quick-opening feeding door 13 is closed, the feeding chamber 11 can be sealed, so that the sterilization pressure vessel 1 becomes a closed pressure vessel. The crusher 2 is placed in the middle of the sterilization pressure vessel 1.

[0035] In this embodiment, the driving assembly includes a first hinge mechanism, and the lower portion of the pressing plate 21 is connected to the side of the feed chamber 11 close to the crusher 2 through the first hinge mechanism.

[0036] In this embodiment, the first hinge mechanism includes a first bearing seat 22, a second bearing seat 23, and a rotating shaft 24. The first bearing seat 22 and the second bearing seat 23 are both fixedly connected to the feed chamber 11. The rotating shaft 24 is fixedly connected to the press plate 21. The two ends of the rotating shaft 24 are respectively rotatably engaged with the first bearing seat 22 and the second bearing seat 23. The first hinge mechanism enables the press plate 21 to rotate about the axis of the rotating shaft 24.

[0037] In this embodiment, the driving assembly further includes a first driving member;

[0038] The first driving member includes a second hinge structure, a transmission rod 27 and a first driving element 26, the first driving element 26 is connected to the head end of the transmission rod 27, the transmission rod 27 is tilted downward from the outside to the inside and extends into the feed chamber 11, and the tail end of the transmission rod 27 is connected to the pressing plate 21 through a second hinge structure, the second hinge structure includes a slide groove arranged on the pressing plate 21 and a sliding shaft connected to the tail end of the transmission rod 27, the sliding shaft is connected to the slide groove in a sliding and rotating manner; the transmission rod 27 is driven to move by the first driving element 26, so that the pressing plate 21 can rotate toward the crusher 2 or toward the inner wall of the sterilization pressure container 1.

[0039] The first drive element 26 can be a motor, pneumatic cylinder, or hydraulic cylinder with a retractable output shaft. This first drive member drives the blank holder 21 to rotate. When material compression is required, the output shaft of the first drive element 26 extends, driving the drive rod 27. The tail end of the drive rod 27 rotates the blank holder 21, causing the first drive member to rotate the blank holder 21 toward the crusher 2. This destabilizes the material bridge above the crusher 2, facilitating the flow of material into the crusher 2 for crushing.

[0040] After the material pressing is completed, the output shaft of the first driving element 26 is shortened to drive the transmission rod 27 to move, and the tail end of the transmission rod 27 pulls the pressing plate 21 to rotate, so that the first driving component rotates the pressing plate 21 in the direction away from the crusher 2. Finally, the pressing plate 21 moves to a position close to the inner wall of the sterilization pressure vessel 1. At this time, the pressing plate 21 is in a vertical posture along the up and down direction to prevent affecting the feeding from the feed port to the feed chamber 11.

[0041] Since the force application position of the transmission rod 27 of the first driving component is near the second hinge structure, the rotation center of the pressing plate 21 is near the first hinge structure, the force application position of the first driving component is staggered with the rotation center, the lever arm is longer, and the transmission efficiency and energy transfer efficiency of the driving mode of the first driving component are higher.

[0042] When the transmission rod 27 rotates the pressing plate 21, the axes of the transmission rod 27 and the output shaft of the first driving element 26 remain unchanged, and the slide groove and the sliding shaft can slide and rotate relative to each other. Therefore, when the pressing plate 21 is driven to rotate by the transmission rod 27, the axis position of the rotating shaft 24 is fixed, and the pressing plate 21 rotates with the axis of the rotating shaft 24 as the rotating axis. The matching structure of the slide groove and the sliding shaft can prevent the transmission rod 27, the pressing plate 21 and the feed chamber 11 from getting stuck.

[0043] In this embodiment, a guide baffle 29 is provided on the top of the pressing plate 21; the pressing plate 21 is a flat plate, an arc-shaped plate, a grid plate or a perforated plate.

[0044] The guide baffle 29 is an inclined plate. When the pressing plate 21 approaches the inner wall of the sterilization pressure vessel 1, the upper end of the guide baffle 29 abuts against the inner wall of the sterilization pressure vessel 1, and the lower end of the guide baffle 29 is connected to the pressing plate 21. The guide baffle 29 prevents material from falling into the gap between the pressing plate 21 and the side wall of the sterilization pressure vessel 1, preventing material from affecting the resetting of the pressing plate 21. At the same time, because there is a gap between the pressing plate 21 and the rotating shaft 24 and the inner wall of the feed chamber 11, and the lower portion of this gap is completely open, debris during the crushing process that enters the gap will also fall into the feed chamber 11 through the open lower portion of the gap.

[0045] The grid plate and the perforated plate can reduce the weight of the press plate 21 .

[0046] Example 2:

[0047] like Figure 3-Figure 6 As shown, a pre-crushing vertical medical waste disinfection treatment device in this embodiment includes a disinfection pressure vessel 1, a crusher 2, a lateral pressing mechanism 3 and a control system 4. The lateral pressing mechanism 3 includes a pressing plate 21 and a driving component connected to the pressing plate 21. The crusher 2 and the pressing plate 21 are both arranged in the disinfection pressure vessel 1; the control system 4 is used to control the working state of the driving component so that the driving component drives the pressing plate 21 to move toward the crusher 2 or toward the inner wall of the disinfection pressure vessel 1.

[0048] The pre-crushing vertical medical waste disinfection treatment device in this embodiment can be a device that uses high-temperature steam disinfection, a device that uses microwave disinfection, or a device that uses high-temperature steam and microwave coordinated disinfection.

[0049] In this embodiment, the disinfection pressure vessel 1 includes a feed cabin 11 located above the crusher 2 and a disinfection and sterilization cabin 12 located below the crusher 2. The feed cabin 11 is provided with a feed quick-opening door 13, and the disinfection and sterilization cabin 12 is provided with a discharge quick-opening door 14. The pressing plate 21 is located in the feed cabin 11 between the feed quick-opening door 13 and the crusher 2.

[0050] In this embodiment, the driving assembly includes a first hinge mechanism, and the lower portion of the pressing plate 21 is connected to the side of the feed chamber 11 close to the crusher 2 through the first hinge mechanism.

[0051] In this embodiment, the first hinge mechanism includes a first bearing seat 22, a second bearing seat 23, and a rotating shaft 24. The first bearing seat 22 and the second bearing seat 23 are both fixedly connected to the feed chamber 11. The rotating shaft 24 is fixedly connected to the press plate 21. The two ends of the rotating shaft 24 are respectively rotatably engaged with the first bearing seat 22 and the second bearing seat 23. The first hinge mechanism enables the press plate 21 to rotate about the axis of the rotating shaft 24.

[0052] In this embodiment, the drive assembly also includes a second drive member; the second drive member includes a second drive element 25 and a transmission structure 28, and the second drive element 25 is rotatably connected to the rotating shaft 24 through the transmission structure 28; the rotating shaft 24 is driven to rotate by the second drive element 25 and the transmission structure 28, so that the pressing plate 21 can rotate toward the crusher 2 or toward the inner wall of the sterilization pressure container 1.

[0053] The second drive element 25 can be a motor, pneumatic cylinder, or hydraulic cylinder with a rotatable output shaft. The transmission structure 28 can be a belt drive, gear drive, or chain drive. The transmission structure 28 drives the output shaft of the second drive element 25, thereby rotating the movable shaft 32 and the rotating shaft 24. When material pressing is required, the second drive element 25, transmission structure 28, and rotating shaft 24 drive the pressure plate 21 to rotate toward the crusher 2. This destabilizes the material bridge above the crusher 2, facilitating the flow of material into the crusher 2 for crushing.

[0054] After the material pressing is completed, the pressing plate 21 is driven to rotate in the direction away from the crusher 2 by the second driving element 25, the transmission structure 28 and the rotating shaft 24. Finally, the pressing plate 21 moves to a position close to the inner wall of the sterilization pressure vessel 1. At this time, the pressing plate 21 is in a vertical posture in the up and down direction to prevent affecting the feeding from the feed port to the feed chamber 11.

[0055] In this embodiment, a first mounting tube portion 36 for mounting the first bearing seat 22 is provided on the feed chamber 11. The first bearing seat 22 includes a first tube seat 31, a movable shaft 32 and a sealing gasket 33. The first tube seat 31 is connected to the first mounting tube portion 36. The movable shaft 32 is inserted into the first tube seat 31 and the first mounting tube portion 36 in a rotatable manner. One end of the movable shaft 32 is fixedly connected to the rotating shaft 24, and the other end of the movable shaft 32 extends out of the first tube seat 31 and is connected to the transmission structure 28. The sealing gasket 33 is arranged between the first tube seat 31 and the movable shaft 32.

[0056] Specifically, a through hole is provided in the middle of the first tube seat 31, and an internal thread is provided in the hole. The first mounting tube portion 36 is provided with an external thread. The internal thread of the first tube seat 31 is connected to the external thread of the first mounting tube portion 36. The movable shaft 32 and the rotating shaft 24 can rotate synchronously (for example, connected by a flat key or a spline). The output shaft of the second driving element 25 rotates through the transmission structure 28 to drive the movable shaft 32 and the rotating shaft 24 to rotate together.

[0057] In this embodiment, a second mounting tube portion 37 for mounting the second bearing seat 23 is provided on the feed chamber 11. The second bearing seat 23 includes a second tube seat 34 and a sealing sleeve 35. The second tube seat 34 is inserted into the second mounting tube portion 37. One end of the second tube seat 34 is connected to the second mounting tube portion 37. The other end of the second tube seat 34 is connected to the rotating shaft 24 in a manner that allows relative rotation. The sealing sleeve 35 is arranged at the end of the second mounting tube portion 37 away from the inner cavity of the feed chamber 11.

[0058] Specifically, the second mounting tube portion 37 is provided with an internal thread, and the second tube seat 34 and the sealing sleeve 35 are provided with external threads.
