Description

Technical Field

[0001] The present invention relates to the technical field of medical waste treatment, and in particular to a high-temperature crushing treatment device for medical waste pollution sources and a purification process thereof. Background Art

[0002] Medical waste refers to waste that is directly or indirectly infectious, toxic or otherwise harmful and is generated during medical treatment, prevention, health care and other related activities. The existing methods for medical waste treatment include: sanitary landfill, high-temperature incineration and high-pressure steam sterilization. Each method has its own characteristics and scope of application, and needs to be selected according to the type of medical waste and actual conditions. The specific classifications of medical waste are mainly the following: infectious waste, injury waste, drug waste, chemical waste. If the above-mentioned medical waste is not properly disposed of, there will be great safety hazards.

[0003] In the prior art, for example, a Chinese utility model with publication number CN214637032U, entitled: A medical waste crushing and processing machine that is easy to repair, records that the crushing machine for medical waste is usually a shearing type crushing machine, which has two corresponding main shafts, and the moving knife group is mounted on the main shaft. It cooperates with the fixed knife group installed on the side plate to form a whole, and the different knife groups are in a bite state. However, for small medical waste such as glass slides, test tubes, and ampoules, and the test tubes and ampoules have a relatively smooth shape and structure, they will be misaligned with the shearing and crushing components, that is, they are not easy to contact with the shearing and crushing components. In addition, some disposable items used in clinical practice, such as disinfectant cotton and disposable non-woven fabrics, need to be properly disposed of after use. However, if a shearing method is used for crushing, it is difficult to repeatedly and accurately place the disposable items in the shearing knife group for shearing operations, and the items will be wrapped around the outside of the scissors, affecting the effective crushing of the disposable items by the scissors knife group, which in turn leads to incomplete crushing of medical waste, a long time, and affects the crushing efficiency. Therefore, a high-temperature crushing treatment equipment for medical waste pollution sources and a purification process thereof are designed here to solve the above problems.

DETAILED DESCRIPTION

[0018] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] This embodiment provides a high-temperature crushing treatment device for medical waste pollution sources, such as Figure 1 , Figure 2 As shown, it includes: a treatment barrel 1, one end of the treatment barrel 1 is an open structure, the opening structure is sealed with a detachable cover 11, the cover 11 is connected to the opening structure by a threaded connection, the cover 11 is installed in the opening structure, closes the opening structure, and ensures the sealing of the treatment barrel 1 during the treatment process.

[0020] like Figure 1 and Figure 3As shown, a material guide cylinder 14 is provided at the upper end of the processing cylinder 1 in a lifting manner. Specifically, a wide-mouthed material hopper is extended from the upper end of the material guide cylinder 14, and at least two cylinders 13 are fixed to the upper end of the processing cylinder 1. At least two extension plates are laterally extended from the top end of the outer wall of the material guide cylinder 14, and the telescopic end of the cylinder 13 is fixedly connected to the bottom wall of the extension plate; a guide cylinder 12 is fixed to the upper end of the processing cylinder 1, which is slidably sleeved with the outer wall of the material guide cylinder 14, and the two cylinders 13 are synchronously extended and retracted, which can drive the material guide cylinder 14 to be lifted and lowered up and down along the axial direction of the guide cylinder 12. In addition, a plurality of hanging rods 32 are suspended on the top wall of the treatment tube 1, an umbrella-shaped cover 31 is fixed between the bottom ends of the plurality of hanging rods 32, a blocking sleeve 3 is fixed on the upper end of the umbrella-shaped cover 31, the blocking sleeve 3 is slidably fitted with the inner wall of the guide tube 14, a turntable 33 is provided on the upper end of the blocking sleeve 3, the hanging rod 32 is used to lift the umbrella-shaped cover 31 and the blocking sleeve 3 in the treatment tube 1, the turntable 33 blocks the blocking sleeve 3, after the medical waste is thrown into the guide tube 14 from the wide-mouth feed hopper, it will be piled on the turntable 33, the guide tube 14 will be selectively raised and lowered, the guide tube 14 will slide up and down along the outer wall of the blocking sleeve 3, the guide tube 14 will selectively detach from the blocking sleeve 3, and control whether the guide tube 14 is connected with the feed channel of the treatment tube 1. When the guide barrel 14 slides upward and is separated from the blocking sleeve 3, the bottom opening of the guide barrel 14 is connected to the treatment barrel 1, and medical waste (used ampoules, sterile cotton used in surgery, and disposable non-woven fabrics) will fall into the treatment barrel 1. When the guide barrel 14 falls downward, it will slide and fit on the outer wall of the blocking sleeve 3 again, blocking the feeding channel for medical waste to enter the guide barrel 1. When no medical waste enters the treatment barrel 1, the treatment barrel 1 is in a relatively closed state.

[0021] like Figure 3 As shown, a hollow crushing seat 4 is built into the inner bottom wall of the processing cylinder 1, and feed ports are opened on both side walls of the hollow crushing seat 4. A fixed pull rod is vertically suspended on the inner top wall of the hollow crushing seat 4, and a transmission rod 42 is inserted and connected to the bottom end of the fixed pull rod for transverse rotation. A connecting rod 43 is fixed to the radial side wall of the transmission rod 42, and a shoveling rod 44 is provided at the end of the connecting rod 43. A plurality of shearing blades 45 located in the hollow crushing seat 4 are provided on the inner bottom wall of the processing cylinder 1, and the side wall of the shearing blade 45 facing the rotation direction of the shoveling rod 44 is a shearing blade 45a, and a shearing gap is reserved between two adjacent shearing blades 45, as shown in FIG. Figure 7 and Fig.10 At the same time, a motor is fixed to the bottom wall of the treatment cylinder 1, and the output end of the motor is connected to a main shaft 5 that rotates and extends into the treatment cylinder 1. The outer wall of the main shaft 5 is fixedly sleeved with a bevel gear 1 51 located in the hollow crushing seat 4. Two transmission rods 42 are provided and are located on both sides of the main shaft 5. The two transmission rods 42 are coaxially distributed, and a bevel gear 2 47 is fixed at one end close to each other. The bevel gear 1 51 is meshed with the two bevel gears 2 47 respectively, as shown in FIG. Figure 6As shown, the motor provides rotational power for the main shaft 5, and synchronously drives the two bevel gears 47 to rotate through the bevel gear 1 51. The two transmission rods 42 rotate in opposite directions, so the connecting rod 43 connected to the two transmission rods 42 and the shovel rod 44 at the end of the connecting rod 43 also rotate in opposite directions.

[0022] Moreover, the end of the main shaft 5 is fixedly connected to the bottom wall of the turntable 33; Figure 4 As shown, during the rotation of the main shaft 5, the turntable 33 can be driven to rotate synchronously on the upper end of the blocking sleeve 3. The advantage of this design is that when the guide barrel 14 slides upward to disengage from the blocking sleeve 3, the rotation of the turntable 33 will generate a rotational centrifugal force, and the medical waste piled on the turntable 33 will be thrown out due to the rotational centrifugal force of the turntable 33, thereby accelerating the speed of introducing the medical waste into the treatment barrel 1 and preventing the medical waste from remaining on the turntable 33. A plurality of diverter blocks 34 are fixed on the upper end of the turntable 33, and the plurality of diverter blocks 34 are distributed in an annular structure at intervals on the upper end surface of the turntable 33. During the rotation of the turntable 33, the plurality of diverter blocks 34 rotate synchronously, and the side walls of the diverter blocks 34 are used as blocking members for the sliding of the medical waste relative to the turntable 33, so that the medical waste is thrown out laterally along the side walls of the diverter blocks 34.

[0023] Although the two groups of shovel rods 44 rotate in opposite directions, they are both located in the hollow crushing seat 4, and the medical waste entering the treatment cylinder 1 will fall on the upper end surface of the hollow crushing seat 4. Figure 8 As shown, the upper end surface of the hollow crushing seat 4 is an arc-shaped structure, so the medical waste falling on the upper end surface of the hollow crushing seat 4 will slide along the inclined surface of the arc-shaped structure to the inner bottom wall of the processing tube 1. The inner bottom wall of the processing tube 1 is a circular structure, so the medical waste will roll from the feed ports on both sides of the hollow crushing seat 4 to the inner space of the hollow crushing seat 4. The rotation of the two groups of shovel rods 44 with opposite rotation directions will push the medical waste located in the hollow crushing seat 4 through the shear gap and the shear blade 45a to perform crushing and shearing operations.

[0024] Specifically, for the used ampoule bottle, when it falls from the feed channel to the upper end surface of the hollow crushing seat 4, its upper side wall is a receiving crushing surface with an arc-shaped structure, and a vertical height is set between the receiving crushing surface and the feed channel opening. The medical waste falls to the receiving crushing surface, which is a one-time unpowered crushing. In other words, it falls from the vertical height of the bottom opening of the guide cylinder 14 to the upper end surface of the hollow crushing seat 4, and the gravitational potential energy is converted into dynamic potential energy. Then, the moment the ampoule bottle hits the upper end surface of the hollow crushing seat 4, the ampoule bottle is easy to break. Here, the pre-crushing treatment of the ampoule bottle is realized. The advantage is that after the ampoule bottle is broken, the bottle body is broken and no longer has good rolling properties like before it is broken. The arc-shaped structure side wall in the treatment cylinder 1 and the feed port form an arc-shaped entry channel, which is the path for medical waste to enter the hollow crushing seat 4 after a one-time unpowered crushing. The crushed medical waste, such as ampoule bottle residue, falls along the receiving and crushing surface onto the arc-shaped side wall at the bottom of the processing cylinder 1, and slides along the arc-shaped side wall toward the feed port side into the hollow crushing seat 4 in real time.

[0025] When the pre-crushed ampoule residue rolls down along the circular inclined surface of the bottom wall of the processing tube 1 into the hollow crushing seat 4, it will be concentrated near the shear blade 45, that is, the center of the bottom of the hollow crushing seat 4. The bottom of the hollow crushing seat 4 here has no side walls, so the ampoule residue is located at the center of the bottom of the processing tube 1. During the rotation of the shovel rod 44, multiple shovel rods 44 will push the ampoule residue through the shear gap and the shear blade 45a. When the ampoule residue is quickly pushed to contact the shear blade 45a, it can be sheared and crushed by the shear blade 45a in an instant. When a large volume of ampoule residue passes through the shear gap, if the width of the ampoule residue is wide, it cannot cross the gap and will rest against the side of the shear blade 45. As the shovel rod 44 continues to rotate, it forms a further driving force for the large volume of ampoule residue, which can further crush the large volume of ampoule residue. The two groups of shoveling rods 44 with different rotation directions can repeatedly squeeze and crush the ampoule residues in the hollow crushing seat 4 until all the ampoules are crushed.

[0026] For the processing operation of the used sterilized cotton and disposable non-woven fabric, when it falls from the feed channel onto the upper end surface of the hollow crushing seat 4, it slides along the upper end surface of the circular arc structure of the hollow crushing seat 4 to the circular structure of the inner bottom wall of the processing cylinder 1. Although the sterilized cotton and disposable non-woven fabric are very light, after the sterilized cotton and disposable non-woven fabric slide off the upper end surface of the hollow crushing seat 4, they will fall on the position where the hollow crushing seat 4 and the inner bottom wall of the processing cylinder 1 are installed. Fig. 9From the structure shown, the inner wall of the treatment cylinder 1 is a circular structure, and the sterilized cotton and disposable non-woven fabric can slide along the circular structure to the bottom of the hollow crushing seat 4, that is, the sterilized cotton and disposable non-woven fabric will be concentrated near the shear blade 45. In this case, there is no need to set a toggle member to push the sterilized cotton and disposable non-woven fabric into the hollow crushing seat 4. The shoveling rod 44 will push the sterilized cotton and disposable non-woven fabric located in the hollow crushing seat 4 through the shear gap and the shear blade 45a. When the sterilized cotton and disposable non-woven fabric are quickly pushed to contact the shear blade 45a, they can be sheared and torn by the shear blade 45a in an instant. Two groups of shoveling rods 44 with different rotation directions can repeatedly push and shear the sterilized cotton and disposable non-woven fabric in the hollow crushing seat 4 until all the sterilized cotton and disposable non-woven fabric are torn and sheared and processed into small particles or small flocs. The volume of medical waste is reduced and subsequent processing is also convenient.

[0027] In this embodiment, a baffle 46 is further fixed to the upper end of the shear blade 45, and the side wall of the baffle 46 facing the rotation direction of the shovel rod 44 is a cutting blade 46a. Fig.11 and Fig.12 As shown, by adding more baffles 46, one of the purposes is to form a blocking component on one side of the shear blade 45 to prevent medical waste from being pushed over the shear blade 45 without being sheared and crushed by the shear blade 45a of the shear blade 45, thereby affecting the shearing and crushing efficiency. Another purpose is that by adding baffles 46, all medical waste will be pushed by the shoveling rod 44 and the connecting rod 43 to move toward the shear blade 45 and baffles 46, and all medical waste will contact the shear blade 45a and the slitting blade 46a. When the ampoule residue is quickly pushed to contact the shear blade 45a, it can be instantly sheared and crushed by the shear blade 45a and the slitting blade 46a. When the sterilizing cotton and disposable non-woven fabric pass through the shear blade 45a and the slitting blade 46a, they are sheared and processed into small particles or powder. Moreover, by adding baffles 46, it can be used as a hard part to knock and crush the ampoule pushed by the shoveling rod 44 and the connecting rod 43.

[0028] Bevel blades 461 may be provided on both side walls of the baffle 46, and knife grooves 431 may be provided on both side walls of the connecting rod 43 to which the bevel blades 461 face. Fig.13 As shown, this design is aimed at the rapid shearing operation of sterilized cotton and disposable non-woven fabrics, that is, when the sterilized cotton and disposable non-woven fabrics are pushed by the connecting rod 43 through the gap between two adjacent baffles 46, they will contact the blades of the bevel blades 461 on both sides of the baffles 46 to achieve further shearing operation. The side wall of the connecting rod 43 is provided with a knife groove 431, which matches the bevel blade 461. When the connecting rod 43 rotates and passes through the gap between two adjacent baffles 46, it will not touch the bevel blade 461.

[0029] During the crushing process, the medical waste after use will carry pathogens and easily cause secondary hazards. Therefore, in the above-mentioned crushing process, when there is no medical waste input, the guide tube 14 is lowered and adjusted, and is slidably connected to the outer wall of the blocking sleeve 3, so that the entire processing tube 1 is in a relatively sealed state. The inner wall of the blocking sleeve 3 is fixedly connected to a heating tube 35, and the heating tube 35 is spirally wound along the outer wall of the main shaft 5, and does not contact the outer wall of the main shaft 5. The conductive line is embedded in the suspension rod 32, extending along the umbrella cover 31 and the inner wall of the blocking sleeve 3, and connected to the heating tube 35 circuit, so that the heating tube 35 is heated to generate high temperature. Here, the bottom wall of the umbrella cover 31 is attached with aluminum foil, which can play a role in accelerating the diffusion of heat. At the same time, a ventilation plate 36 is horizontally fixed to the bottom wall of the umbrella cover 31. The ventilation plate 36 is provided with ventilation holes, and an air guide tube 38 is embedded in the ventilation plate 36. The radial side wall of the main shaft 5 is fixed with a plurality of fan blades 37 located in the guide tube. Figure 5 As shown, the fan blades 37 rotate synchronously with the main shaft 5 to generate downward fanning wind. The heat in the umbrella-shaped cover 31 follows the fanning of the fan blades 37, enters from the upper end of the air guide tube 38, and is discharged from the lower end opening into the treatment tube 1, as shown in FIG. Figure 3 The cold air in the treatment tube 1 will flow back from the ventilation holes of the ventilation plate 36 to the inside of the umbrella cover 31, as shown in FIG. Figure 3 The arrows B and B1 indicate the direction of return flow.

[0030] The above process can quickly increase the stability of the entire treatment tube 1, so that the medical waste can be sheared and crushed under high temperature regulation. As the temperature continues to rise, the oxygen in the treatment tube 1 will be gradually consumed, so that the medical waste is heated to an extremely high temperature in an oxygen-deficient or hypoxic environment. The heating temperature of the heating tube 35 is at least above 850 degrees Celsius. Oxygen reacts with dioxin toxic gases to decompose and be consumed. The medical waste is heated to a high temperature in an oxygen-deficient or hypoxic environment, and the dioxin toxic gas overflow path generated during the high-temperature treatment is disconnected, so that the benzene ring organic matter that is a dioxin precursor disappears. At this time, no matter what the temperature range is, dioxin substances will not be generated again. This is an irreversible reaction process.

[0031] When the feed channel is closed, the treatment tube 1 is temporarily sealed. Through the built-in hot air circulation passage, as the temperature continues to rise, the oxygen in the treatment tube 1 reacts with the dioxin toxic gas to decompose and be consumed, and the medical waste is heated to a high temperature in an oxygen-deficient or low-oxygen environment, disconnecting the overflow passage of the dioxin toxic gas generated during the high-temperature treatment process.

[0032] It effectively avoids the emission of dioxin toxic gases that may be produced during high-temperature treatment and reduces pollution to the atmosphere. At the same time, the oxygen-free environment controls the generation of secondary pollutants and further protects the environment. Moreover, high-temperature treatment during pyrolysis can effectively degrade harmful substances in medical waste, such as pathogens, toxic chemicals, etc., and reduce their potential threat to the environment. High-temperature treatment can effectively kill pathogens and microorganisms in medical waste, reduce their infectiousness and infection risks, and ensure public health safety. By treating medical waste in a closed high-temperature environment, the risk of the spread of pathogens and harmful substances during the treatment process is reduced, and the risk of infection is reduced.

[0033] In summary, the original intention of the applicant's design is to integrate multiple functions such as crushing, shearing and high-temperature reduction of waste gas emissions. For the crushing and treatment of medical waste such as ampoules and disinfectant cotton, on the one hand, it is necessary to consider the issue of medical and health safety, and on the other hand, it is necessary to avoid rapid and effective crushing and treatment, while avoiding the problem that the debris of the ampoule will not splash and injure the crushing operator and the disinfectant cotton can be effectively sheared. To this end, the first element is that after the ampoules are put into the guide barrel 14 in batches from the wide-mouth feed hopper, the turntable 33 selectively opens the bottom opening of the guide barrel 14. When opened, the ampoule can enter the treatment barrel 1. When closed, the ampoule cannot enter, and the treatment barrel 1 is in a temporarily closed state. In this way, it does not affect the feeding of materials, meets the necessary closed conditions for high-temperature crushing treatment, and does not cause debris to splash. The second element is to utilize the height difference to drop the ampoule bottle entering the processing cylinder 1 to undergo an unpowered crushing operation. At the same time, the broken ampoule bottle residue will slide along the arc-shaped side wall in the processing cylinder 1 to the feed port and enter the hollow crushing seat 4. The ampoule bottle will repeatedly and rigidly contact the shear blade 45 to perform a secondary powered crushing operation. Similarly, when the sterilized cotton and disposable non-woven fabric are quickly pushed by the shovel rod 44 to contact the shear blade 45a, they can be instantly sheared and torn apart by the shear blade 45a. Two sets of shovel rods 44 with different rotation directions can repeatedly push and shear the sterilized cotton and disposable non-woven fabric in the hollow crushing seat 4 until all the sterilized cotton and disposable non-woven fabric are torn and sheared and processed into small particles or small flocs. The third factor is also very critical. During the high-temperature crushing process, dioxin toxic gases will be produced. Then, through the built-in hot air circulation passage, as the temperature continues to rise, the oxygen in the treatment cylinder 1 reacts with the dioxin toxic gases to decompose and be consumed. The medical waste is heated to a high temperature in an oxygen-deficient or low-oxygen environment, and the dioxin toxic gas overflow passage generated during the high-temperature treatment is disconnected, ensuring that the crushing treatment is carried out under safe and effective conditions without pollution.

[0034] It should be noted that in order to achieve the requirement of rapid heating, the wind speed needs to be controlled. Specifically, under normal circumstances, the airflow generated by the fan is evenly distributed in the space.

[0035] Calculate wind speed using air volume: Air volume (CFM) is the volume of air that a fan can move per minute. Assuming that this volume of air is evenly distributed in a circular area in front of the fan, the wind speed can be estimated by the following formula: V=AQ, Where V is the wind speed (unit: feet / minute or meters / second), Q is the fan's air volume (CFM), and A is the area of ​​the hypothetical circular area (unit: square feet or square meters). The area A can be calculated by the diameter D of the fan: A=π(2D)2, where D is the diameter of the fan blade 37.

[0036] In summary, it can be clearly known that the greater the wind speed V is, the faster the hot air flows, and the faster the temperature in the treatment tube 1 rises.

[0037] A discharge port is provided at one end of the hollow crushing seat 4 close to the opening structure of the processing cylinder 1. A hinged seat is fixed to the upper side wall of the discharge port. A stop cover 41 is hingedly connected to the hinged seat. The stop cover 41 selectively blocks the discharge port. Figure 8 As shown, the cover 11 is installed in the opening structure of the treatment barrel 1 in which the outer wall of the stopper 41 fits with the inner wall of the cover 11, thereby ensuring that during the shearing and crushing process, the stopper 41 will not be opened arbitrarily to cause a large amount of medical waste to overflow.

[0038] After the medical waste treatment is completed, the cover 11 is removed, the opening structure is opened, and the treated medical waste is taken out through the opening structure into the treatment cylinder 1 .

[0039] In order to improve the efficiency of medical waste extraction, specifically, Figure 1 As shown, it also includes a bracket 2, one end of which extends upward with two supporting parts, and the top ends of the side walls of the two supporting parts are respectively rotatably connected to the two sides of the opening structure of the processing tube 1, and a cylinder 21 is fixed on the upper side of the other end of the bracket 2. The telescopic end of the cylinder 21 is connected to an inverted door frame 22, and the two ends of the inverted door frame 22 are respectively rotatably connected to the two sides of the end of the processing tube 1 away from the opening structure. When the cylinder 21 is started, the telescopic end of the cylinder 21 is stretched to lift the inverted door frame 22, so that the end of the processing tube 1 away from the opening structure is tilted, and the sealing cover 11 is opened. The blocking cover 41 is affected by the tilt and flips around the hinge seat to open the discharge port, and the sheared and crushed medical waste will be discharged, reducing the labor of manual operation.

[0040] 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.
