Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a sedimentation tank structure for medical waste disinfection wastewater. Background Technology

[0002] Medical wastewater comes from various sources, such as hospital treatment rooms, laboratories, wards, laundry rooms, X-ray rooms, and operating rooms, all of which discharge large amounts of disinfection wastewater. The sources and composition of this wastewater are very complex. Because medical wastewater is infectious, it needs to be disinfected and purified before being discharged. The sedimentation process, as an early treatment step, mainly separates and precipitates the decomposable and adsorbable impurities in the wastewater to reduce the intensity of subsequent treatment.

[0003] As shown in the sludge removal mechanism for sedimentation tanks used in medical wastewater treatment disclosed on the China Patent Network (publication announcement number CN222238936U), after sedimentation and separation are completed, the sedimentation tank of this type can use a motor to drive the chain and the scraper on the surface to rotate. The rotation of the scraper will scrape off the impurities and sludge attached to the bottom of the sedimentation tank, causing them to be concentrated into the inside of the sludge collection tank. The sludge and impurities inside the sludge collection tank can be sucked into the sewage pipe by the sewage pump and then discharged from the inside of the outlet pipe, thereby achieving the sludge removal effect inside the sedimentation tank.

[0004] However, the aforementioned disclosed patents and existing market-used medical wastewater sedimentation tanks still have some shortcomings: while existing sedimentation tanks possess a self-cleaning function for settling impurities, their self-cleaning effectiveness is limited, often failing to effectively clean impurities in corners and other hard-to-reach areas. Therefore, those skilled in the art have provided a sedimentation tank structure for medical disinfection wastewater to address the problems mentioned in the background section. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sedimentation tank structure for medical waste disinfection wastewater, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sedimentation tank structure for medical waste disinfection, comprising a sedimentation tank, wherein the sedimentation tank is configured as a conical structure; a semi-circular collecting cylinder is provided at the bottom of the conical sedimentation tank, the collecting cylinder has a first drive shaft inside, and a first spiral auger is provided along the axial direction of the first drive shaft; a discharge cylinder is provided at one end of the collecting cylinder, the discharge cylinder has a second drive shaft inside, and a second spiral auger is provided along the axial direction of the second drive shaft; a third drive shaft is provided on both sides of the sedimentation tank, and the third drive shaft has at least one set of pendulum hammers along its axial direction; a drive assembly is provided at one end of the sedimentation tank to drive the first drive shaft, the second drive shaft, and the third drive shaft to rotate synchronously.

[0009] As a further technical solution of this utility model: a first pulley is provided at one end of the third drive shaft, and a second pulley is provided on one side of the central shaft of the drive gear. The first pulley and the second pulley are connected by a transmission belt.

[0010] As a further technical solution of this utility model: the other end of the sedimentation tank is provided with a drive motor that drives the first drive shaft.

[0011] As a further technical solution of this utility model: the feed inlet of the unloading cylinder is provided with a wide opening close to the first spiral auger.

[0012] As a further technical solution of this utility model: the pendulum hammer is provided in multiple sets along the axial direction of the third drive shaft, and the hammer head of the pendulum hammer is made of rubber material.

[0013] This utility model provides a sedimentation tank structure for medical waste disinfection wastewater, which has the following advantages compared with the prior art: The sedimentation tank structure for medical waste disinfection wastewater, after the medical wastewater has been separated by sedimentation, can be driven by a drive component.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5This utility model provides a technical solution for a sedimentation tank structure for medical waste disinfection wastewater: A sedimentation tank structure for medical waste disinfection wastewater includes a sedimentation tank 1, which is a conical structure. The bottom of the sedimentation tank 1 has a semi-circular collecting cylinder 3. Inside the collecting cylinder 3 is a first drive shaft 12, and along its axial direction is a first auger 13. One end of the collecting cylinder 3 has a discharge cylinder 4, inside which is a second drive shaft 14, and along its axial direction is a second auger 15. Third drive shafts 5 are located on both sides of the sedimentation tank 1, and each third drive shaft 5 has at least one set of pendulum hammers 6 along its axial direction. One end of the sedimentation tank 1 is equipped with a drive mechanism that drives the first drive shaft 12, the second drive shaft 14, and the third drive shaft 5 to rotate synchronously. The other end of the sedimentation tank 1 is equipped with a drive motor 2 that drives the first drive shaft 12. Based on the integrated drive of the drive assembly by the drive motor 2, on the one hand, the combined operation of the first drive shaft 12 and the first spiral auger 13 is driven to spirally push the medical waste impurities after sedimentation and separation, and to circulate the medical waste impurities to one end of the discharge cylinder 4. At the same time, the combined operation of the second drive shaft 14 and the second spiral auger 15 is driven to spirally push and discharge the medical waste impurities in the discharge cylinder 4, and to discharge the impurities after sedimentation and separation by self-discharge. On the other hand, while discharging, the pendulum hammer 6 on the third drive shaft 5 is driven to swing back and forth, hammering the sedimentation tank 1 to generate vibration, causing the medical waste impurities adhering to the inner wall of the sedimentation tank 1 to fall off and gather into the collection cylinder 3 for comprehensive self-cleaning treatment. Specifically: The drive assembly includes a first bevel gear 17 axially arranged along the first drive shaft 12 and a second bevel gear 18 disposed at the top of the second drive shaft 14. The first bevel gear 17 and the second bevel gear 18 mesh with each other, and a housing 16 is provided on the outer side of the first bevel gear 17 and the second bevel gear 18. When the drive motor 2 is working, it drives the first drive shaft 12 to rotate. During the rotation of the first drive shaft 12, it drives the combined transmission of the first bevel gear 17 and the second bevel gear 18, which in turn drives the second drive shaft 14 to rotate. By utilizing the synchronous operation of the two sets of drive shafts, the first spiral auger 13 and the second spiral auger 15 are driven to rotate respectively. By utilizing the rotation of the first spiral auger 13, the medical waste impurities collected in the collection cylinder 3 are spirally pushed to the discharge cylinder 4. At the same time, by utilizing the rotation of the second spiral auger 15, the medical waste impurities pushed into the discharge cylinder 4 are spirally pushed to discharge (the discharge port of the discharge cylinder 4 is installed in a valve with a butterfly valve structure, so that it is closed when not in use and open when in use).

[0018] As a further embodiment, the drive assembly also includes a sector gear 11 disposed at one end of the first drive shaft 12 and two sets of drive gears 10 disposed on one side of the sector gear 11. The sector gear 11 intermittently meshes with one set of drive gears 10, and the two sets of drive gears 10 mesh with each other (to generate driving forces in opposite directions, driving the two sets of third drive shafts 5 to rotate symmetrically, pushing the axially oriented pendulum hammers 6 to swing in opposite directions and strike the sedimentation tank 1). A transmission belt 8 is provided between the drive gears 10 and the third drive shafts 5. One end of the third drive shaft 5 is provided with a first pulley 7. A second pulley 9 is provided on one side of the central shaft of 0. The first pulley 7 and the second pulley 9 are connected by a transmission belt 8. When the first drive shaft 12 rotates, it drives the sector gear 11 to rotate, which intermittently meshes with one of the drive gears 10, driving the corresponding drive gear 10 to rotate intermittently. At the same time, it drives the combination of the second pulley 9, the transmission belt 8, and the first pulley 7 to rotate, generating a driving force that pushes the third drive shaft 5 to rotate intermittently. When the third drive shaft 5 is under force and rotates, it drives the pendulum 6 to strike the sedimentation tank 1. When it is not under force, the pendulum 6 self-resets under the action of gravity.

[0019] It should be noted that the pendulum hammer 6 is provided with multiple sets along the third drive shaft 5, and the hammer head of the pendulum hammer 6 is made of rubber material. By making the hammer head of the pendulum hammer 6 of rubber material, the hard impact of its strike is reduced.

[0020] In addition, the feed inlet of the unloading cylinder 4 is provided with a wide opening 41 close to the first spiral auger 13. By providing a wide opening 41 at the feed inlet of the unloading cylinder 4, medical waste impurities can be better guided and unloaded.

[0021] The working principle of this utility model is as follows: When using a sedimentation tank to treat medical disinfection wastewater, the medical disinfection wastewater and flocculant are added to sedimentation tank 1 in a certain proportion for flocculation and sedimentation treatment. After flocculation, the upper layer of clear water is extracted, while the lower layer of medical waste impurities undergoes self-cleaning unloading treatment. Specifically: The drive motor 2 is controlled to work, driving the first drive shaft 12 to rotate. The transmission combination of the first bevel gear 17 and the second bevel gear 18 drives the second drive shaft 14 to rotate synchronously, driving the first spiral auger 13 and the second spiral auger 15 to rotate respectively. The first spiral auger 13 rotates and pushes the medical waste impurities collected in the collection cylinder 3 to the discharge cylinder 4 in a spiral. The second spiral auger 15 pushes the medical waste impurities pushed into the discharge cylinder 4 to be discharged in a spiral. Furthermore, while the first drive shaft 12 rotates, it drives the sector gear 11 to rotate, intermittently meshing with one set of drive gears 10, driving the corresponding drive gear 10 to rotate intermittently. The meshing of the two sets of drive gears 10 generates driving forces in opposite directions, respectively driving the combination of the second pulley 9, transmission belt 8, and first pulley 7 to rotate, generating a driving force that pushes the third drive shaft 5 to rotate intermittently. When the third drive shaft 5 is under force and rotates, it drives the pendulum hammer 6 to strike the sedimentation tank 1. When it is not under force, the pendulum hammer 6 self-resets under the action of gravity. By using the striking of the pendulum hammer 6, the medical waste impurities adhering to the inner wall of the sedimentation tank 1 are vibrated and dematerialized, causing them to converge into the collection cylinder 3 for comprehensive self-cleaning treatment.

[0022] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
