Description

Technical Field

[0001] The invention relates to the technical field of medical waste treatment, and in particular to a microwave plus steam medical waste continuous treatment process. Background Art

[0002] Medical waste refers to waste that is directly or indirectly harmful and is generated by medical and health institutions in related activities. Common medical wastes include infectious wastes, pathological wastes, injury wastes, pharmaceutical wastes, and chemical wastes. If the above medical wastes are not properly disposed of, they will not only occupy land resources, but also pollute water and soil with a large amount of toxic waste residues and waste liquids, and produce harmful gases and pollute the atmosphere. Medical and cleaning personnel are at potential risk of secondary pollution during transportation. Therefore, medical wastes need to be disinfected and sterilized to prevent them from polluting the external environment.

[0003] Although there are corresponding medical waste treatment devices in the prior art that can disinfect and sterilize medical waste, such devices are often small in size and difficult to treat a large amount of medical waste at one time. They have slow processing speeds, high energy consumption, and low automation. When facing major public medical emergencies such as epidemic prevention and control, they are relatively weak. At the same time, according to existing data, the only current treatment technologies that do not produce secondary pollution are high-temperature steam treatment and microwave treatment technology, but high-temperature steam treatment is labor-intensive, and microwave technology mainly relies on imports. Both are less economical, so this application has developed a continuous treatment form of microwave plus steam treatment technology to solve the above problems. Summary of the invention

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] 1. In the present application, high-temperature and high-pressure steam is introduced into the sterilization chamber through a steam generator, and then microwaves are generated by a microwave generator to cause the water molecules inside the sterilization chamber to move rapidly and the temperature to rise, so that the inside of the sterilization chamber is maintained at a high temperature and high pressure state, thereby sterilizing the bacteria in the medical waste. The pressure inside the sterilization chamber is maintained at 200 kpa, and the temperature is maintained at 140 degrees Celsius. The entire sterilization process lasts for five minutes. Compared with the existing technology, medical waste can be fully disinfected and sterilized.

[0023] 2. In the present application, by configuring the rotating shaft, bevel gear, bevel gear, fixed column and rubber strip, when the motor is running, the rotating shaft, bevel gear and bevel gear can drive the fixed column to rotate while revolving along with the rotating shaft, so that the rubber strip can push and stir the medical waste, and then move it to the top of the material, so that the medical waste made of metal material is deposited below the whole material, and the medical waste made of plastic material is deposited above the whole material.

[0024] 3. Since the amount of medical waste processed each time is different, in this application, through the arrangement of the electric slider, stirring plate, air chamber and extrusion plate, the more medical waste enters the sterilization chamber, the greater the distance the extrusion plate slides inward, so that when the amount of medical waste in the sterilization chamber is more, the more steam can pass through the conical groove, and the amount of medical waste is directly proportional to the content of steam, so that the steam inside the sterilization chamber can maintain an appropriate content, avoiding poor sterilization effect due to insufficient steam and excessive temperature due to excessive steam affecting subsequent medical waste recovery.

[0025] 4. In the present application, by setting up the hydraulic cylinder, push column and reflective plate, on the one hand, the microwaves are reflected back and forth between the surface of the reflective plate and the metal medical waste, thereby reducing the path of microwave reflection, so that the microwaves can quickly sterilize the plastic medical waste above; on the other hand, when the extrusion plate slides, it will drive the push column to move synchronously. At this time, the hydraulic oil in the hydraulic cylinder will generate thrust on the reflective plate, thereby causing the reflective plate to slide upward along the inner wall of the stirring plate. At this time, the position of the reflective plate is raised to avoid excessive accumulation of medical waste and affect the reflection path between the reflective plate and the metal medical waste.

[0026] In summary, in the present application, an appropriate amount of high-temperature steam can be injected into the sterilization chamber according to the amount of medical waste, and with the cooperation of the microwaves emitted by the microwave generator, the inside of the sterilization chamber can be kept in a high temperature and high pressure state to sterilize the bacteria in the medical waste. The equipment has good stability and does not cause damage due to sudden changes in temperature. At the same time, it changes the previous intermittent processing that caused extremely small processing capacity, high energy consumption, large leakage and other problems, and the processing capacity of equipment of the same scale is more than 5 times that of the previous one.

It is used to control the opening and closing of the discharge pipe 35. The lower end of the discharge pipe 35 passes through the outer shell to discharge the sterilized medical waste.

[0045] A microwave plus steam medical waste continuous treatment process mainly includes the following process steps:

[0046] S1, transporting, sending the medical waste from the feeding system 1 to the crushing system 2 through the elevator for crushing;

[0047] S2, crushing, the crushing system 2 uses a two-stage low-speed shearing crushing machine to crush the medical waste, and the crushed medical waste is transported to the sterilization system by the conveying system 12 for sterilization treatment;

[0048] S3, sterilization. When the medical waste reaches the sterilization system 2, the steam generator 21 and the microwave generator 22 are started to introduce high-temperature and high-pressure steam into the sterilization chamber 3. The microwaves cause the water molecules in the sterilization chamber 3 to move rapidly and the temperature rises. The pressure in the sterilization chamber 3 is maintained at 200 kPa and the temperature is maintained at 140 degrees Celsius. The sterilization process lasts for five minutes.

[0049] S4, exhaust, during the sterilization process, start the circulating air pump 23 to extract the harmful gas in the sterilization chamber 3, and transport it to the cooler for condensation treatment, and then purify it through the biological filter and deodorization filter, and finally discharge the harmless gas into the air;

[0050] S5, inspection. After the sterilization is completed, the medical waste is discharged to the outside of the sterilization chamber 3 through the discharge pipe 35. The staff will take samples for inspection and compare them with the samples before sterilization. The inspection results will be inspected and recorded.

[0051] The specific working principle of the present invention is as follows. After the medical waste enters the sterilization chamber 3, the motor 4 is started, so that the output end of the motor 4 drives the rotating shaft 41 to rotate. The rotation of the rotating shaft 41 will drive the rotating column 44 to rotate along the surface of the fixed block 45. The rotation of the rotating column 44 will drive the bevel gear 46 to move synchronously. Since the bevel gear 46 is meshed with the bevel gear 47, the bevel gear 46 will rotate along the surface of the bevel gear 47 at this time, and then the rotating column 44 drives the bevel gear 46 to rotate along the axis of the rotating shaft 41. The bevel gear 46 will rotate along its own axis, so that when the fixed column 48 revolves along the axis of the rotating column 44, it will rotate along the axis of the bevel gear 46, and then the fixed column 48 drives the rubber strip 49 to revolve. At the same time, rotation occurs, and the rubber strip 49 will push and stir the medical waste. Since the rubber strip 49 is made of rubber material, when it encounters medical waste made of metal material (such as scalpels, needle fragments) during the rotation process, the rubber strip 49 will deform due to its heavy weight, and thus it is impossible to push it from the bottom to the top. Medical waste made of plastic material (such as infusion bottles, blood collection tubes) will deform due to its soft material when being crushed by the crushing system 11, and the crushing system 11 cannot completely crush it into fragments. At this time, the rubber strip 49 will push it to the top of the material when stirring it, so that the medical waste made of metal material is deposited below the whole material, and the medical waste made of plastic material is deposited above the whole material.

[0052] When the materials are separated, the steam generator 21 and the microwave generator 22 are started. The steam generator 21 will transport the steam to the air groove 42 opened inside the rotating shaft 41 through the air pipe 43. The steam will enter the hose 511 along the air groove 42, and then enter the air chamber 52 opened inside the stirring plate 5 through the hose 511. At this time, the electric slider 51 is started to slide downward along the inner wall of the rotating column 44. The sliding of the electric slider 51 will drive the stirring plate 5 to move synchronously, so that the stirring plate 5 moves downward and contacts the medical waste, so that the stirring plate 5 stirs the medical waste. At this time, the medical waste will squeeze the squeezing plate 53 on the stirring plate 5, and then the squeezing plate 53 will slide from the outside to the inside along the inner wall of the stirring plate 5 and squeeze the spring 54. The sliding of the squeezing plate 53 will cause the conical groove 56 to change from a closed state to an open state. At this time, the steam in the air chamber 52 will pass through the conical groove 56 and be discharged to the bottom of the medical waste through the filter 531, and the metal medical waste at the bottom will be steam sterilized. As the stirring plate 5 rotates continuously, medical waste will be accumulated on the surface of the stirring plate 5 in the rotation direction. At this time, the rotation of the stirring plate 5 is stopped, and the microwave generator 22 is started at the same time, so that the microwave generator 22 emits microwaves to sterilize the plastic medical waste at the upper end. Since the metal medical waste at the bottom will reflect the microwaves, part of the microwaves will reach the surface of the reflecting plate 59 when reflected by the metal medical waste. At this time, the reflecting plate 59 will reflect the microwaves again, so that the microwaves are reflected back and forth between the surface of the reflecting plate 59 and the metal medical waste, thereby reducing the path of microwave reflection, so that the microwaves can quickly sterilize the plastic medical waste above. At the same time, the microwaves that are not reflected by the reflecting plate 59 will increase the temperature of the water molecules in the sterilization chamber 3, so that the interior of the sterilization chamber 3 can maintain an overall high temperature and high pressure environment, thereby improving the sterilization effect.

[0053] Since the amount of medical waste processed each time is different, when the amount of medical waste entering the sterilization chamber 3 is more, the distance that the extrusion plate 53 slides inward is greater. At this time, since the slope of the conical groove 56 is the same as that of the conical column 55, when the amount of medical waste in the sterilization chamber 3 is more, the more steam can pass through the conical groove 56, and the amount of medical waste is proportional to the content of steam, so that the steam inside the sterilization chamber 3 can maintain a suitable content, avoiding insufficient steam causing poor sterilization effect, and excessive steam causing excessive temperature affecting subsequent medical waste recovery. At the same time, when the extrusion plate 53 slides, it will drive the push column 58 to move synchronously. The movement of the push column 58 will squeeze the hydraulic oil in the hydraulic cylinder 57. At this time, the hydraulic oil in the hydraulic cylinder 57 will generate thrust on the reflector 59, so that the reflector 59 slides upward along the inner wall of the stirring plate 5. At this time, the position of the reflector 59 is raised, avoiding excessive accumulation of medical waste and affecting the reflection path between the reflector 59 and the metal material medical waste.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
