Description

Technical Field

[0001] This utility model relates to a solid waste disposal device, specifically an intelligent on-site disposal device for medical solid waste. Background Technology

[0002] Currently, medical waste disposal companies generally use high-temperature incineration equipment to dispose of medical waste, and the incinerated products are then landfilled, thus completing the medical waste disposal process.

[0003] However, there are some shortcomings in the collection, transportation, and disposal:

[0004] (1) The process of collecting medical waste requires a lot of manpower and multiple people to hand over the waste, which consumes a lot of human and material resources.

[0005] (2) The entire medical waste transportation cost is very high. In-hospital transportation requires a lot of labor costs, while out-of-hospital transportation involves medical institutions transporting waste to disposal companies, which requires a large number of motor vehicles and has high transportation costs. During the out-of-hospital transportation of medical waste, some criminals may take advantage of regulatory loopholes to carry out illegal disposal of medical waste, which poses a serious threat to the environment and public health.

[0006] At the same time, medical waste is infectious and can easily cause environmental pollution and cross-infection during transportation.

[0007] (3) Traditional medical waste disposal technologies are relatively outdated and cannot meet current environmental protection and safety requirements. For example, incineration facilities in some areas have limited processing capacity and may generate secondary pollution; landfill facilities may occupy a large amount of land resources and pose a risk of groundwater pollution.

[0008] To address the pollution from incineration without increasing the size of additional equipment and thus the required floor space, it is necessary to improve upon the existing equipment. Utility Model Content

[0009] To address the challenges of collecting and transporting medical waste and the large land area required, this utility model provides an intelligent on-site disposal device for medical solid waste.

[0010] This utility model provides the following technical solution:

[0011] The intelligent medical solid waste on-site disposal equipment includes a disposal equipment body, a circulating water system, a cooling device, a gas filtration device, a radiator, and a control system. The disposal equipment body is sequentially connected to the cooling device and the gas filtration device, and is also connected to the radiator. The circulating water system is connected to the disposal equipment body and introduces water into the disposal equipment body. The disposal equipment body has a disposal chamber, which is equipped with a static device, a rotary crushing mechanism, and a high-temperature pyrolysis gasification mechanism. The rotary crushing mechanism is located inside the static device, and the high-temperature pyrolysis gasification mechanism is arranged around the periphery of the static device. The high-temperature pyrolysis gasification mechanism includes an annular hot steam pipe and multiple guide pipes arranged on the annular hot steam pipe. The high-temperature steam from the disposal equipment body enters the cooling device for cooling treatment, and the gas discharged from the disposal equipment body is filtered by the gas filtration device.

[0012] Furthermore, a surrounding air duct is provided above the annular hot steam pipe.

[0013] Furthermore, a tilting mechanism and a weighing instrument are provided on one side of the main body of the disposal equipment. The tilting mechanism includes a tilting frame and a trash can placed on the tilting frame.

[0014] Furthermore, a guide plate is installed on the tipping frame, the trash can is connected to one end of the guide plate, and the other end of the guide plate is aligned with the sealing cover of the main body of the disposal equipment.

[0015] Furthermore, a disinfectant spray is installed above the treatment chamber.

[0016] Furthermore, the rotary crushing mechanism includes a stirring central shaft and stirring rods arranged on both sides of the stirring central shaft. The bottom of the stirring central shaft is driven by a motor outside the static device via a conveyor belt.

[0017] Furthermore, the gas filtration device includes a housing, a built-in filter box, and a filter plate. The bottom of the housing is provided with an air inlet, and the top of the housing is provided with an air outlet. The built-in filter box is installed inside the housing, and the filter plate is installed on the built-in filter box. The built-in filter box is filled with filter holes.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The main body of the treatment equipment uses a dynamic rotating mechanism to drive the medical waste to move at high speed. During the high-speed movement, the medical waste is processed into granular and flocculent waste through the longitudinal shear force, transverse shear force and pressure between the static device and the rotating crushing mechanism on the side of the treatment chamber, in order to reduce the volume of medical waste. A high-temperature pyrolysis gasification mechanism is added to the static device to gradually pyrolyze the medical solid waste through high-temperature steam. With the help of air jets from the circumferential air duct, the pyrolysis is more thorough.

[0020] This process eliminates the need for complex transfer procedures and allows for self-production and self-sales. This equipment uses mechanical technology to dispose of medical waste, which, compared to traditional methods, eliminates the need for incineration, saves energy, is environmentally friendly, and contributes to sustainable development. It also saves labor and is human-friendly, reducing the infectiousness of medical waste. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-3 The intelligent medical solid waste on-site disposal equipment provided by this utility model includes a disposal equipment body 100, a circulating water system 200, a cooling device 300, a gas filtration device 400, a radiator 500, and a control system. The disposal equipment body 100 is connected to the cooling device 300 and the gas filtration device 400 in sequence. The disposal equipment body 100 is also connected to the radiator 500. The circulating water system 200 is connected to the disposal equipment body 100 and introduces water into the disposal equipment body 100. The disposal equipment body 100 has a disposal chamber 10, and the disposal chamber 10 is equipped with a static device 11, a rotary crushing mechanism 12, and a high-temperature pyrolysis gasification mechanism 14. Figure 8 As shown), the rotary crushing mechanism 12 is installed inside the static device 11, and the high-temperature pyrolysis gasification mechanism 14 is arranged around the perimeter of the static device 11. The high-temperature pyrolysis gasification mechanism 14 includes an annular hot steam pipe 141 and multiple guide pipes 142 arranged on the annular hot steam pipe. The high-temperature steam coming out of the main body of the treatment equipment 100 enters the cooling equipment 300 for cooling treatment, and the gas discharged from the main body of the treatment equipment 100 is filtered by the gas filtration equipment 400.

[0036] The main body of the treatment equipment utilizes the longitudinal and transverse shear forces between the static device and the rotary crushing mechanism on the inner side of the treatment chamber, as well as the pressure between the static and dynamic structures, to process medical waste into granular and flocculent waste. The waste is then treated through anaerobic high-temperature pyrolysis. A high-temperature pyrolysis gasification mechanism is added to the static device, using high-temperature steam to gradually pyrolyze the medical solid waste. Combined with air jets from the circumferential duct, the pyrolysis is more thorough.

[0037] Figure 4 , 5 As shown, a tilting mechanism 20 and a weighing instrument 30 are provided on one side of the main body 100 of the disposal equipment. The tilting mechanism 20 includes a tilting frame 21 and a garbage bin 22 placed on the tilting frame 21. A ladder 60 is provided on the side of the main body 100 of the disposal equipment.

[0038] A guide plate 23 is installed on the tilting frame 21. The garbage can 22 is connected to one end of the guide plate 23, and the other end of the guide plate 23 is aligned with the sealing cover 40 of the main body 100 of the disposal equipment.

[0039] Multiple disinfection sprayers 50 are installed above the treatment chamber 10.

[0040] Figure 7 As shown, the gas filtration device 400 includes a housing 401, an internal filter box 402, and a filter plate 403. The housing 401 has an air inlet 4011 at its bottom and an air outlet 4012 at its top. The internal filter box 402 is installed inside the housing 401, and the filter plate 403 is mounted on the internal filter box 402. The internal filter box 402 is filled with filter holes 4021. Gas enters the gas filtration device, passes through a chemical filter and multiple filter screens, and is discharged outdoors at low altitude.

[0041] Figure 6 As shown, the rotary crushing mechanism 12 includes a stirring central shaft 121 and stirring rods 122 arranged on both sides of the stirring central shaft. The bottom of the stirring central shaft 121 is driven by a motor 13 outside the static device 11 via a conveyor belt.

[0042] The control system includes a control cabinet 600 and a power cabinet 700.

[0043] Figure 9 As shown, a surrounding air duct 143 is installed above the annular hot steam pipe 141. The high-temperature steam continuously melts the medical solid waste, and the melting effect is even better when combined with the surrounding hot air jet. The air source for the surrounding air duct is provided from outside the treatment chamber.

[0044] The rotary pulverizing mechanism drives the medical waste in a high-speed circular motion, generating centrifugal force that propels the waste towards the bulkhead. The formula for centrifugal force is... F c It is centrifugal force, m is the mass of medical waste, ω 2 ω is the rotational angular velocity, and r is the rotational radius.

[0045] Longitudinal shear force and transverse shear force

[0046] Because of the relative motion between the dynamic rotating mechanism and the static device, a shear force will be generated. Assume the linear velocity of the rotating mechanism is v, and the normal velocity at the contact point between the medical waste and the static device is v0. n The tangential velocity is v t According to the principle of velocity decomposition, .

[0047] Shear force F t With tangential velocity v t According to Newton's law of internal friction in viscous fluid mechanics, , where μ is the dynamic viscosity of the fluid, A is the contact area, and is the rate of change of tangential velocity in the direction perpendicular to the contact surface.

[0048] Pressure between static and dynamic structures

[0049] Pressure F between dynamic and static structures p This can be analyzed based on the force balance relationship. During rotation, centrifugal force causes the medical waste to press against the static device on the inner side of the chamber, generating pressure. Assuming the pressure of the medical waste on the static device is uniformly distributed under the action of centrifugal force, the magnitude of the pressure is related to the component of the centrifugal force perpendicular to the static device. If the angle between the centrifugal force and the normal direction of the static device surface is θ, then the pressure F... p =F c cosθ.

[0050] When longitudinal shear force, transverse shear force, and pressure between static and dynamic structures act on medical waste, the waste will deform and break. According to the yield criterion in mechanics of materials, when the shear stress and normal stress acting on medical waste reach a certain level, the waste material will yield and break down, and will gradually be processed into granules and flocculent particles.

[0051] During the disposal process, the main treatment chamber is sealed and under negative pressure. Auxiliary heating is used during the disposal process, and the maximum temperature inside the treatment chamber can reach 150°C. The medical waste is disinfected and sterilized, which meets the requirements of GB39707-2020 "Standard for Pollution Control of Medical Waste Treatment and Disposal".

[0052] The cooling equipment uses water cooling to cool the main equipment and the emitted high-temperature steam.

[0053] The gas filtration equipment consists of a chemical filter and a multi-stage filter screen to filter the gas discharged from the main unit. The filtered gas meets the emission requirements of regulations and standards and can be directly discharged into the atmosphere.

[0054] The main body of the treatment equipment is equipped with a disinfection spray to disinfect bacteria and eliminate odors in the treatment chamber.

[0055] The PLC control module is the brain of the new intelligent on-site medical solid waste disposal system. All parameters during the disposal process, including speed, pressure, and temperature, are controlled by the control module.

[0056] Once the intelligent medical solid waste on-site disposal system is deployed, it can be put into operation after being powered on. Medical waste is fed into the main disposal unit via the tilting mechanism, and operation can be started with a single button. The specific disposal method is as follows:

[0057] S1. The operator places the medical waste to be disposed of on the tilting mechanism 20 of the main body 100 of the disposal equipment. The system automatically weighs and records and uploads the weight of the current medical waste. After the weighing is completed, the system automatically starts the tilting mechanism 20 to release the material.

[0058] S2. During the disposal process, in order to ensure sufficient processing capacity, the equipment will automatically compact the disposed medical waste. After disposal, the sealing cover will automatically close 40, and the equipment can be started.

[0059] S3. After the equipment is started, the medical waste is ground into granular and fibrous forms by the longitudinal shear force, transverse shear force and pressure between the static device 11 and the rotary crushing mechanism 12 on the inner side of the main body of the equipment 100, thereby reducing the volume of the waste.

[0060] S4. During the disposal process, the disposal chamber 10 is oxygen-deficient or oxygen-free. Through the impact, squeezing and friction between the medical waste and the disposal chamber 10, the temperature inside the disposal chamber 10 continuously rises to 135°C, which performs preliminary disinfection and sterilization on the medical waste. Then, it continues to rise to 150°C to complete thorough disinfection and sterilization. At the same time, the pathogens carried on the surface of the medical waste are pyrolyzed.

[0061] S5. During the disposal process, the system will use disinfectant spray 50 to cool down the main unit and the disposed waste. The discharged high-temperature steam enters the cooling equipment 300, is cooled and filtered, and then discharged.

[0062] S6. Gas generated from medical waste treatment enters the gas filtration equipment 400, is filtered by a chemical filter and a multi-stage filter screen, and is discharged outdoors at low altitude.

[0063] S7. After the treatment is completed, the treated waste is automatically discharged through the discharge port, the collection equipment automatically packages and processes it, and automatically cleans the inside of the treatment chamber 10 to ensure that the chamber is clean.

[0064] To improve processing efficiency, after disinfection is completed inside the main unit compartment, the temperature of the main unit equipment is kept constant under the control of the PLC, saving time on heating and cooling.

[0065] Intelligent thermal energy technology utilizes the heat generated during the disposal of medical waste through impact / friction with the disposal equipment. The equipment intelligently controls the efficiency and total amount of heat generation through algorithms, and uses the generated heat to disinfect and sterilize the medical waste during disposal.

[0066] Deploying one or more new intelligent on-site medical waste disposal systems within hospitals or departments allows medical waste to be directly and harmlessly disposed of after it is generated locally, eliminating the need for centralized disposal outside the hospital. This not only prevents illegal disposal of medical waste by unscrupulous individuals exploiting regulatory loopholes but also avoids cross-contamination of medical waste and reduces management and transportation costs. Medical waste disposed of using the new intelligent on-site medical waste disposal equipment meets the requirements of GB39707-2020 "Standard for Pollution Control of Medical Waste Treatment and Disposal," and the resulting waste can be treated according to the standards for domestic waste. This not only reduces environmental pollution from medical waste but also ensures the safety of personnel and the environment, while simultaneously lowering disposal costs for medical institutions.

[0067] The following effects can be achieved through the construction and implementation of this plan:

[0068] 1. The implementation of this plan can help medical institutions save on labor and management costs;

[0069] 2. Reduce transportation and disposal costs for medical institutions and improve the efficiency of medical waste disposal;

[0070] 3. The use of new technologies and equipment protects the environment and eliminates pollution;

[0071] 4. Standardize the management of medical waste to reduce the risks that medical waste poses to society.

[0072] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
