Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to a medical waste feeding and conveying device. Background Technology

[0002] Microwave disinfection is the result of the combined effects of microwave and biological effects. It allows microwave energy to interact directly with bacteria for rapid sterilization. The microwave disinfection equipment uses a disinfection frequency of 2450MHz. When microwaves pass through a medium, the molecules in the medium vibrate and rub against each other billions of times per second, generating a large amount of heat. Due to the different absorption coefficients of microwave energy by intracellular substances, the intracellular substances are heated unevenly, affecting cell metabolism. The oscillation frequency of microwaves is close to the inherent frequency of organic molecules. Intracellular proteins, especially amino acids and polypeptides, selectively absorb microwave energy, changing their molecular structure, destroying the activity of biological enzymes, and affecting cell metabolism. The combined effect of these effects achieves rapid and thorough sterilization. The process flow of medical waste microwave disinfection is as follows: Medical waste placed in a medical waste transfer box is transported to the medical waste disposal center by a medical waste transport vehicle, unloaded into the medical waste storage room, and then fed into the hopper of the microwave processing equipment by a conveying device for crushing. The conveying device is mainly responsible for transporting the materials.

[0003] Medical waste mainly refers to contaminated waste generated by hospitals that has come into contact with patients' blood, flesh, etc., such as used cotton balls, gauze, adhesive tape, wastewater, disposable medical instruments, and postoperative waste. Before entering the microwave processing equipment, these wastes are transported via conveyor belts. Due to the large number of bacteria on the surface of the wastes, the surface of the conveyor belts is easily contaminated with bacteria during transportation. Existing conveying devices do not have corresponding cleaning mechanisms, resulting in a large number of bacteria remaining on the surface of the conveyor belts. To address this, we propose a medical waste feeding and conveying device. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] To address the technical problem that existing medical waste conveying devices lack corresponding cleaning mechanisms, leading to easy bacterial contamination of the conveyor belt surface, this invention provides a medical waste feeding and conveying device that can clean and disinfect the conveyor belt surface, preventing bacterial contamination.

[0031] It should be noted that the medical waste feeding and conveying device described in this utility model is used in, but not limited to, the field of conveyor belts. For ease of explanation, this utility model only uses the application of the medical waste feeding and conveying device in the field of conveyor belts as an example. The principle of the medical waste feeding and conveying device applied to other types of equipment is essentially the same as that applied to the field of conveyor belts, and will not be described in detail here.

[0032] Please see Figure 1 The present invention provides a medical waste feeding and conveying device, comprising:

[0033] The machine casing 1 has a feed box 2 at the top. The feed box 2 has a hollow structure and an opening at the top. The conveyor belt 3 is located inside the machine casing 1 and at the bottom of the feed box 2. The water guide shell 4 is inclined and located below the conveyor belt 3. The water guide shell 4 has multiple filter holes 41.

[0034] The cleaning mechanism 5 includes a water tank 6, an agitation end 62, a spraying end 7, a cleaning end 8, and a drying end 9. The water tank 6 is located on the outer wall of the housing 1. The agitation end 62 is located inside the water tank 6 and is used to agitate the cleaning liquid. The spraying end 7 is located on the water guide shell 4 and is used to spray the surface of the conveyor belt 3. The cleaning end 8 is located on the water guide shell 4 and is used to clean the surface of the conveyor belt 3. The drying end 9 is installed inside the housing 1 and is used to dry the surface of the conveyor belt 3.

[0035] The process involves installing a water guide shell 4 inside the housing 1 and below the conveyor belt 3, with filter holes 41 on the water guide shell 4 to facilitate the discharge of cleaning liquid. A water tank 6 is installed on the outer wall of the housing 1 to store disinfectant. The disinfectant and liquid are thoroughly mixed by the stirring end 62. The mixed liquid is extracted by the spray end 7 and sprayed onto the conveyor belt 3 during transportation. During the spraying process, the surface of the conveyor belt 3 is further cleaned by the cleaning end 8, and then dried by the drying end 9. The process flow for microwave disinfection of medical waste is as follows: Medical waste placed in a medical waste transfer box is transported to the medical waste disposal center by a medical waste transfer vehicle, unloaded into the medical waste storage room, and then fed into the hopper of the microwave treatment equipment by the feeding system for crushing. Medical waste with a particle size of less than 5cm passes through the screen into the rotating hopper and then into the microwave disinfection pipeline. At the same time, a steam generator injects high-temperature steam into the microwave disinfection pipeline. The process involves preheating and heating, followed by microwave sterilization at a time of ≥45 minutes and a temperature of ≥95℃. A portion of the steam is discharged as wastewater; most remains attached to the medical waste residue, while a small portion, along with the exhaust gas from the microwave sterilization system, is treated using the equipment's built-in "primary filter + high-efficiency filter + activated carbon device." The medical waste is conveyed and agitated within the microwave sterilization pipeline using a spiral conveyor system, ensuring uniform heating and sterilization for optimal results. The sterilized medical waste residue is discharged through the discharge system. The microwave sterilization equipment employs a fully automated system integrating hydraulic lifting, material crushing, microwave sterilization, and spiral discharge. After entering the crushing system, the microwave sterilization and conveying systems are activated. Once crushed and sterilized, the material is transported to an external storage silo. The final discharged residue is 3-5 cm long, and the bulk density of the processed medical waste is approximately 0.55-0.63 t / m³. 3 The processed medical waste will be reduced in volume by 60%–65% and become unidentifiable.

[0036] To prolong the time that waste spends inside feed hopper 2, please refer to [link / reference needed]. Figure 4 and Figure 6 The feed box 2 has several inclined plates 21 installed inside.

[0037] In order to delay the falling time of waste, inclined plates 21 with opposite angles are set on both sides inside the feed box 2, which can effectively prolong the falling time of waste and avoid excessive material transport on the conveyor line.

[0038] To improve the mixing efficiency of disinfectant solutions, please refer to [link / reference needed]. Figure 1 and Figure 2 The conveyor belt 3 includes a belt body 311, several conveying rollers 312, and a first motor 313. The belt body 311 is located at the lower end of the feed box 2 and inside the machine housing 1. Several conveying rollers 312 are located inside the conveyor belt 3. The output end of the first motor 313 is connected to one of the conveying rollers 312 at the end. The outer wall of the machine housing 1 is provided with a drain pipe 42 that communicates with the water guide shell 4. The upper end of the water tank 6 is provided with a water inlet 61, and the lower end is provided with a drain outlet. The stirring end 62 includes a second motor. The system includes a second motor 621, a first conveying shaft 622, a second conveying shaft 623, a first gear 624, and a second gear 625. The second motor 621 is located outside the water tank 6, and its output end is connected to the first conveying shaft 622. The first conveying shaft 622 is axially positioned inside the water tank 6, and its end is connected to the first gear 624. The second conveying shaft 623 is located at the lower end of the first conveying shaft 622, and one end is connected to the second gear 625. The first gear 624 and the second gear 625 mesh with each other.

[0039] In this embodiment, the conveyor belt 3 is maintained by a belt body 311, multiple conveying rollers 312, and a first motor 313. An external intermediate tensioner is installed inside the belt body 311. This intermediate tensioner is a device used to dynamically adjust the tension in the conveyor belt system, primarily to ensure the belt body 311 maintains stable tension and prevents slippage, deviation, or sagging. A first conveying shaft 622 and a second conveying shaft 623 are installed inside the water tank 6. Both the first and second conveying shafts 622 and 623 are spiral conveying shafts. When the second motor 621 drives the first conveying shaft 622, the first conveying shaft 622 drives the first gear 624. Through the cooperation of the first gear 624 and the second gear 625, the second conveying shaft 623 can be driven synchronously. The operation of the first and second conveying shafts 622 and 623 within the water tank 6 ensures thorough mixing of the disinfectant solution, thereby guaranteeing its subsequent sterilization effect.

[0040] To improve the cleaning efficiency of this equipment for conveyor belt 3, please refer to [link / reference needed]. Figure 1 - Figure 8The spray end 7 includes a water suction pipe 71, a pump body 72, a water guide pipe 73, and several branch pipes 74. The water suction pipe 71 is connected to the water tank 6, and the pump body 72 is installed on the water suction pipe 71. The water outlet of the pump body 72 is connected to the water guide pipe 73. The water guide pipe 73 is provided with several branch pipes 74, which extend into the housing 1 and are located below the conveyor belt 3. Each branch pipe 74 is provided with multiple spray heads 741. The cleaning end 8 includes several first housings 81 and springs corresponding to each of the first housings 81. The damper 82 is provided with a first housing 81 between two adjacent diversion pipes 74. The first housing 81 is provided with a spring damper 82. The telescopic end of the spring damper 82 is connected to a scraper 821. The scraping end of the scraper 821 abuts against the surface of the conveyor belt 3. The drying end 9 includes a mounting shell and a hot air blower 91. The mounting shell is provided inside the machine box 1 and is provided with a hot air blower 91 for drying the surface of the conveyor belt 3. An air outlet mesh plate 92 is detachably connected to the mounting shell. The air outlet mesh plate 92 is coaxial with the air outlet end of the hot air blower 91.

[0041] In this embodiment, disinfectant solution is drawn from water tank 6 through water pipe 71, and guided into multiple diversion pipes 74 through the cooperation of pump body 72 and water guide pipe 73. Multiple spray nozzles 741 on the diversion pipes 74 effectively spray the disinfectant solution onto the conveyor belt 3. The spray nozzles 741 are inclined to ensure better contact between the solution and the surface of the conveyor belt 3. A first housing 81 is also provided between two diversion pipes 74, and a spring damper 82 is installed inside the first housing 81. The spring damper 82 pushes the scraper 821, causing the scraping end of the scraper 821 to abut against the conveyor belt 3, which can effectively clean the stains remaining on the surface of the conveyor belt 3, thereby ensuring the cleaning efficiency of the equipment. The sprayed liquid drips onto the water guide shell 4 and flows through the filter hole 41, and is finally discharged outward through the drain pipe 42. In order to ensure the dryness of the surface of the conveyor belt 3, a hot air fan 91 and an air outlet mesh plate 92 are set to effectively dry the surface of the conveyor belt 3.

[0042] To better understand this utility model, the following is combined with... Figure 1 - Figure 8The working process of the medical waste feeding and conveying device of this utility model is described in detail below: When it is necessary to clean the surface of the conveyor belt 3, the belt body 311 is driven to rotate by the cooperation of the first motor 313 and the conveying roller 312, and the second motor 621 is started. The second motor 621 drives the first conveying shaft 622 to rotate. Through the cooperation of the first conveying shaft 622 and the first gear 624, the second gear 625 is driven to rotate. Through the cooperation of the second gear 625 and the second conveying shaft 623, the first conveying shaft 622 and the second conveying shaft 623 are rotated. The material shaft 623 rotates simultaneously, ensuring that the disinfectant is fully mixed. After mixing, the disinfectant is drawn out through the water pipe 71 and introduced into multiple diversion pipes 74 through the pump body 72 and the water guide pipe 73. The surface of the conveyor belt 3 is sprayed through the spray head 741. During the spraying process, the spring damper 82 in the first housing 81 pushes the scraper 821, causing the scraping end on the scraper 821 to clean the surface of the conveyor belt 3. After cleaning, the conveyor belt 3 passes through the drying area of ​​the hot air blower 91, ensuring that the surface of the conveyor belt 3 is evenly dried.
