Description

Technical Field

[0001] The present invention belongs to the field of medical waste treatment devices, and more specifically relates to an environmentally friendly and energy-saving medical solid waste treatment device. Background Art

[0002] Medical waste, as an inevitable product in the daily operation of medical institutions, has a wide range of sources and is complex. From medical waste generated by patient treatment, such as used syringes, infusion bottles, gauze, etc., to biological samples and chemical reagents discarded in the laboratory, there are many types of medical waste, and the difficulty of handling varies. These wastes not only take up a lot of space, but also become a potential threat to environmental and public health safety because of the harmful components such as viruses, bacteria, and chemicals they may carry.

[0003] The traditional way of handling medical waste is to collect the waste in a centralized manner and then transport it to a medical waste treatment plant far away from residential areas by special vehicles for treatment. However, there are many challenges in this process. First of all, the collection and temporary storage of medical waste faces tremendous pressure. Medical institutions need to ensure that the waste is not illegally discarded or mixed with domestic waste, and prevent risks such as leakage and spread during temporary storage.

[0004] Secondly, medical waste also poses safety risks during transportation. Since the waste may contain sharp objects, corrosive liquids, etc., once a traffic accident or improper operation occurs, it is very easy to cause leakage accidents, which not only pollutes the environment along the way, but also may cause harm to the transporters and surrounding residents.

[0005] Furthermore, the receiving and processing capacity of medical waste treatment plants is also facing challenges. Different types of medical waste require different processing technologies and facilities, and it is often difficult for treatment plants to efficiently and safely process a large amount of waste in a short period of time. In addition, issues such as energy consumption and waste discharge during the treatment process also cause secondary pressure on the environment.

[0006] Therefore, a new solution is needed to solve the above problems. Summary of the invention

[0007] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an environmentally friendly and energy-saving medical solid waste treatment device, which realizes the function of directly treating medical waste within the hospital, eliminating the step of transporting the medical waste to a waste treatment plant, thereby effectively avoiding the risk of leakage and spread of medical waste that may occur during the transportation process.

[0008] To achieve the above object, the present invention provides the following technical solutions: An environmentally friendly and energy-saving medical solid waste treatment device, comprising: Feeding mechanism; A lifting mechanism, the inlet of which is connected to the outlet of the feeding mechanism; A crushing mechanism, the top inlet of which is connected to the outlet of the lifting mechanism; A soaking bucket located below the bottom outlet of the crushing mechanism; The solid-liquid separation device is arranged between the frame and the soaking barrel and is used for separating the solid and the liquid in the soaking barrel.

[0009] The advantages of this solution are at least that: the modular medical waste treatment system designed in this solution can directly treat medical waste in the hospital, eliminating the need to transport medical waste to a waste treatment plant, thereby effectively avoiding the risk of leakage and spread of medical waste during transportation. The operation process is simple, and the medical waste only needs to be put into the preset feeding mechanism, and then, with the assistance of the lifting mechanism, the medical waste is smoothly sent to the crushing mechanism for refinement and processing to form smaller fragments.

[0010] These fragments then fall into a soaking bucket containing disinfectant. Due to the reduced volume, the disinfection efficiency is significantly improved and the space utilization of the soaking bucket is optimized. After the disinfection process is completed, the medical waste will pass through a solid-liquid separation device to effectively separate solids from liquids. This process further reduces the hazard level of the disinfected waste, turning it into ordinary waste, which can then be treated according to the standards for domestic waste.

[0011] In summary, this solution not only improves the efficiency and safety of medical waste treatment, but also simplifies the treatment process, reduces treatment costs, and realizes the transformation of medical waste from high-risk to ordinary domestic waste.

[0012] The present invention is further configured as follows: the lifting mechanism is a spiral track, the spiral track is provided with a lifting conveyor belt along its track direction, and the two ends of the lifting conveyor belt are respectively connected with the feeding mechanism and the crushing mechanism.

[0013] The advantages of this solution are at least that the hazardous waste can be lifted to a high place by a lifting conveyor belt, and after falling from a high place, it can enter the crushing mechanism for crushing, which is convenient and quick.

[0014] The present invention is further configured as follows: the crushing mechanism is a crusher, the top and the bottom of the crusher both have openings, and mutually meshing crushing teeth are installed in the middle.

[0015] The advantage of this solution is at least that the hazardous waste can directly enter the crusher for crushing after falling from the lifting conveyor belt, without the need for additional drive.

[0016] The present invention is further configured to include a pressing mechanism located at the top of the crusher, wherein the movable end of the pressing mechanism corresponds to the top opening position of the crusher.

[0017] The advantages of this solution are at least that the downward pressure mechanism is designed to apply downward pressure to the medical waste, which can significantly improve the efficiency of the crushing process and ensure the stability of the crushing operation. Through the operation of the downward pressure mechanism, the medical waste can more fully contact the blades or other crushing elements of the crushing mechanism, thereby accelerating the crushing speed and allowing the medical waste to be broken into small pieces or fragments more quickly. At the same time, the application of the downward pressure mechanism can also reduce the jamming or blockage phenomenon during the crushing process, ensuring the smoothness and stability of the crushing operation.

[0018] The present invention is further configured to include a liquid purification box connected to the liquid outlet of the soaking barrel, a filtering structure is provided in the liquid purification box, and a reflux pipe connected to the soaking barrel is provided at the outlet of the liquid purification box.

[0019] The advantages of this solution are at least that after the solid-liquid separation step is completed, the disinfectant will be directed to the liquid purification box for detailed filtration. This process is designed to effectively screen out the fine medical waste impurities remaining in the disinfectant to ensure the purity of the disinfectant. The purified disinfectant is safely transported back to the soaking bucket through the reflux pipe for recycling. This design not only improves the utilization efficiency of the disinfectant and reduces resource waste, but also extends the service life of the disinfectant, making the entire medical waste treatment process more environmentally friendly and economical.

[0020] The present invention is further configured to include a solid discharge area connected to the solid outlet of the soaking barrel.

[0021] The advantage of this solution is at least that the solid waste after solid-liquid separation will enter the solid unloading area, thereby achieving the separation of ordinary waste.

[0022] The present invention is further configured as follows: the solid-liquid separation device comprises: The filter cartridge is sleeved inside the soaking barrel; A liquid outlet pipe is arranged at the bottom of the soaking barrel and has a valve thereon; The servo motor 1 is arranged on the frame, and its output shaft is connected to the peripheral wall of the soaking barrel.

[0023] The advantage of this solution is at least that the filter cartridge is equipped with numerous tiny holes, which serve to trap medical waste in the cartridge during the soaking process. When the valve on the liquid outlet pipe is opened, the filtered disinfectant will be discharged smoothly through the liquid outlet pipe. At the same time, the medical waste remaining in the filter cartridge is gradually converted into ordinary solid waste under the action of continuous soaking. Subsequently, the filter cartridge is driven to rotate by servo motor 1, and the solid waste inside is poured out from the opening at the top of the soaking barrel and accurately falls into the solid unloading area below. This process effectively separates the solid and liquid inside the soaking barrel.

[0024] The present invention is further configured as follows: the bottom of the filter cartridge is connected to the second servo motor via a pulley.

[0025] The advantage of this solution is at least that when the servo motor 2 is activated, it drives the filter cartridge to rotate. The purpose of this rotation is to spin dry the solid waste remaining inside the filter cartridge to ensure that there is no excess disinfectant attached to the surface of the waste. Through such a spin-drying step, the disinfectant containing medical waste can be effectively prevented from leaking during the subsequent treatment process, thereby maintaining the cleanliness and safety of the treatment environment.

[0026] The present invention is further configured to include a scraping mechanism for scraping the material in the filter cartridge.

[0027] The present invention is further configured as follows: the scraper mechanism comprises a telescopic rod arranged on a frame, a scraper plate is arranged at a movable end of the telescopic rod, and when the telescopic rod is extended, the scraper plate is close to the inner wall of the filter cylinder.

[0028] The advantage of this solution is at least that when the telescopic rod is extended, the scraper plate is close to the inner wall of the filter cartridge, thereby scraping off the solid waste adhering to the inner wall of the filter cartridge, avoiding the problems of blockage and waste accumulation.

[0029] In summary, the present invention has at least the following advantages: 1. By setting up independent cabins, medical waste can be directly processed in the hospital, avoiding the risk of transportation. After loading, lifting, and crushing, the medical waste falls into the disinfectant soaking bucket to improve the disinfection efficiency. After solid-liquid separation, the waste becomes ordinary garbage and can be treated as domestic garbage. This solution is efficient and safe, simplifies the process, reduces costs, and achieves waste risk reduction.

[0030] 2. By setting up the crushing mechanism and the downward pressure mechanism, medical waste can be crushed, and the efficiency of the crushing process can be significantly improved and the stability of the crushing operation can be ensured.

[0031] 3. By setting up a solid-liquid separation device and a scraping mechanism, the medical waste treatment system can efficiently separate solids and liquids, recycle and purify disinfectants, and thoroughly remove equipment residues, simplify the treatment process, reduce costs, ensure the safe conversion of waste into ordinary domestic waste, promote resource recycling, and comply with environmental protection regulations.

DETAILED DESCRIPTION

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0035] An environmentally friendly and energy-saving medical solid waste treatment device, such as Figure 1 and Figure 2 As shown, including: Feeding mechanism 1; The lifting mechanism 2 has an inlet connected to the outlet of the feeding mechanism 1; Crushing mechanism 3 (such as Figure 3 and Figure 4 As shown), its top inlet is connected to the outlet of the lifting mechanism 2; Soaking bucket 4 (such as Figure 3 and Figure 5 As shown), located below the bottom outlet of the crushing mechanism 3; Solid-liquid separation device 5 (such as Figure 6 As shown), it is arranged between the frame 11 and the soaking barrel 4, and is used to separate the solid and liquid in the soaking barrel 4.

[0036] Among them, in actual use, such as Figure 2 and Figure 3As shown, the soaking barrel 4 should be filled with disinfected and sterilized water for sterilizing medical waste. Relevant hospital staff can directly put medical waste into the preset feeding mechanism 1. Subsequently, with the assistance of the lifting mechanism 2, the medical waste will be smoothly sent into the crushing mechanism 3 for refinement to form smaller fragments.

[0037] These fragments then fall into the soaking barrel 4 containing disinfectant. After the disinfection process is completed, the medical waste will pass through the solid-liquid separation device 5 (as Figure 6 shown), achieving effective separation of solids and liquids. This process reduces the hazard level of the disinfected waste, turning it into ordinary waste, which can then be processed according to the standards of domestic waste, realizing the function of directly treating medical waste within the hospital, eliminating the step of transporting medical waste to the waste treatment plant, and thus effectively avoiding the risk of leakage and diffusion that may occur during the transfer of medical waste.

[0038] In some embodiments, as Figure 2 shown, the feeding mechanism 1 includes a feeding conveyor belt (not shown in the figure) provided on the frame 11. The feeding mechanism 1 is provided with a "C"-shaped enclosure 1001 on the non-exit side of the feeding conveyor belt. Since the exit of the feeding conveyor belt is not blocked, it will not affect the discharge of medical waste from the feeding conveyor belt to the lifting conveyor belt 22. Moreover, the height of the enclosure 1001 is lower than the height of an average adult's arm, so it will not interfere with people pouring medical waste into the feeding mechanism 1.

[0039] As Figure 2 and Figure 3 shown, the lifting mechanism 2 is a spiral track, simply referred to as the spiral track 21. The spiral track 21 is provided with a lifting conveyor belt 22 along its track direction. The two ends of the lifting conveyor belt 22 are respectively connected to the feeding conveyor belt of the feeding mechanism 1 and the crushing mechanism 3. After the medical waste is put into the feeding mechanism 1, it will be lifted by the lifting mechanism 2 and then sent into the crushing mechanism 3 for refinement to form smaller fragments. It is worth mentioning that the connection between the lifting conveyor belt 22 and the crushing mechanism 3 means that it can directly fall into the crushing mechanism 3 through the lifting conveyor belt 22, or other conveyor belts can be added between the two to guide the medical waste on the lifting conveyor belt 22 to the crushing mechanism 3.

[0040] In some embodiments, as Figure 3 and Figure 4As shown, the crushing mechanism 3 is a crusher, and the top and bottom of the crusher are both opened. The middle part of the crusher is equipped with mutually meshing crushing teeth. After the material is lifted, it will enter the crusher from the top opening of the crusher for crushing, and then fall into the soaking bucket 4 below. In order to avoid the medical waste from getting stuck or accelerate the crushing of the medical waste, in a preferred embodiment, the cabin also includes a pressing mechanism 6 located at the top of the crusher. The movable end of the pressing mechanism 6 corresponds to the top opening position of the crusher. The pressing mechanism 6 can be a hydraulic cylinder, a cylinder or a motor screw structure to achieve the pressing action, and by adding a pressure plate at the movable end, the medical waste at the crusher inlet is compacted to accelerate the crushing efficiency. It is worth noting that the movable end of the pressing mechanism 6 can be stored in other positions through the telescopic structure 601 when not in use, so that the medical waste falls into the crusher.

[0041] like Figure 5 and Figure 6 As shown, the crushed medical waste will directly fall into the soaking barrel 4 below, and after soaking, solid-liquid separation will be carried out through the solid-liquid separation device 5. In order to maximize the use of disinfectant and reduce costs, in some embodiments, the cabin also includes a liquid purification box 7 connected to the liquid outlet of the soaking barrel 4. The liquid disinfectant water after solid-liquid separation will enter the liquid purification box 7. A filtering structure (not shown in the figure) is provided in the liquid purification box 7. The filtering structure can be a filter structure or a structure with a purification effect based on the principle of ultraviolet sterilization and filtration. The outlet of the liquid purification box 7 is provided with a reflux pipe (not shown in the figure) connected to the soaking barrel 4. The reflux pipe pumps the filtered disinfectant into the soaking barrel 4 for recycling through a water pump.

[0042] In addition, the cabin also includes a solid unloading area 8 connected to the solid outlet of the soaking barrel 4. A unloading hopper can be directly set up in the solid unloading area 8, or the solid waste can be transported upward by a climbing conveyor belt 801 and then fall into a waste hopper 9 in a designated area. From then on, the disinfected solid waste will fall into the waste hopper 9 and be treated as ordinary waste.

[0043] In order to ensure the solid-liquid separation effect, in a preferred embodiment, Figure 6 As shown, the solid-liquid separation device 5 comprises: The filter cartridge 51 is sleeved inside the soaking barrel 4 and has numerous tiny holes thereon for separating the solid and the liquid in the soaking barrel 4 .

[0044] Liquid outlet pipe 52 (such as Figure 5 As shown in the figure, it is arranged at the bottom of the soaking bucket 4 and is provided with a solenoid valve (not shown in the figure) for discharging liquid. When the solenoid valve on the liquid outlet pipe 52 is opened, the disinfectant filtered by the filter cartridge 51 will be discharged smoothly through the liquid outlet pipe 52.

[0045] The servo motor 1 53 is arranged on the frame 11, and its output shaft is connected to the middle of the side wall of the soaking bucket 4. At the same time, a rotating shaft is also arranged on the other side of the side wall of the soaking bucket 4 relative to the output shaft of the servo motor 1 53, and the rotating shaft is rotatably connected to the frame 11. When the servo motor 1 53 is started, the soaking bucket 4 will be tilted through the rotating shaft, so that the solid waste inside it is poured out from the top opening of the soaking bucket 4 to the solid discharge area 8.

[0046] In order to further ensure the effect of solid-liquid separation, in some embodiments, such as Figure 6 As shown, the bottom of the filter cartridge 51 passes through the soaking barrel 4 and is connected to the servo motor 2 54 through a pulley 55 (the belt on the pulley 55 is not shown) at the passing position. When the servo motor 2 54 is activated, it drives the filter cartridge 51 to rotate. The purpose of this rotation action is to spin dry the solid waste remaining inside the filter cartridge 51 to ensure that there is no excess disinfectant attached to the surface of the waste. Through such a spin-drying step, the disinfectant containing medical waste can be effectively prevented from leaking during the subsequent treatment process, thereby maintaining the cleanliness and safety of the treatment environment.

[0047] In addition, in order to avoid the problem of clogging of the filter cartridge 51 or accumulation of solid waste in the filter cartridge 51, in some embodiments, as Figure 5 The shelter further includes a scraping mechanism 10 for scraping the material in the filter cartridge 51. Figure 7 As shown, the scraper mechanism 10 includes a telescopic rod 101 arranged on the frame 11, and a scraper plate 102 is provided at the movable end of the telescopic rod 101. When the telescopic rod 101 is extended, the scraper plate 102 extends into the inclined filter cylinder 51 and approaches the inner wall of the filter cylinder 51. Since the servo motor 2 54 is not fixed on the frame 11, but is fixed in a relative position to the soaking barrel 4, when the soaking barrel 4 is tilted, the servo motor 2 54 will also tilt. As the servo motor 2 54 starts, the filter cylinder 51 will rotate, so that the scraper can scrape off the solid waste adhered to the inner wall of the filter cylinder 51.

[0048] The working process and beneficial effects of the present invention are as follows: The modular medical waste treatment system designed in this scheme realizes the function of directly treating medical waste in the hospital, eliminating the step of transporting medical waste to a waste treatment plant, thereby effectively avoiding the risk of leakage and spread of medical waste during transportation. The operation process is simple, and the medical waste only needs to be put into the preset feeding mechanism 1, and then with the assistance of the lifting mechanism 2, the medical waste is smoothly sent to the crushing mechanism 3 for refinement and processing to form smaller fragments.

[0049] These fragments then fall into the soaking bucket 4 containing disinfectant. Due to the reduced volume, not only the disinfection efficiency is significantly improved, but also the space utilization of the soaking bucket 4 is optimized. After the disinfection process is completed, the medical waste will pass through the solid-liquid separation device 5 to achieve effective separation of solids and liquids. The liquid disinfectant water can also be recycled. This process further reduces the hazard level of the disinfected waste, turning it into ordinary waste, which can then be treated according to the standards of domestic waste.

[0050] In summary, this solution not only improves the efficiency and safety of medical waste treatment, but also simplifies the treatment process, reduces treatment costs, and realizes the transformation of medical waste from high-risk to ordinary domestic waste.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
