[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1:

[0028] Please see attached Figure 1 -Attached Figure 4 The embodiment of the present invention provides a medical hazardous waste treatment device based on friction rotary cutting, comprising a sterilization cylinder 1, the outer wall of the sterilization cylinder 1 is fixedly connected to a fixing frame 2, a rotating tool 4 is arranged at the bottom of the sterilization cylinder 1, and a driving device is arranged below. The outer wall of the driving device is fixedly connected to the fixing frame 2 through a bracket 3, and the rotating tool 4 is driven by the driving device to rotate, so as to rotary cut and stir the medical waste in the sterilization cylinder 1, and a speed difference is generated between the rotating tool 4 and the medical waste. The top of the sterilization cylinder 1 is opened, and a cylinder cover 5 is arranged at the opening. A hydraulic device is arranged between the cylinder cover 5 and the sterilization cylinder 1, and the cylinder cover 5 is driven to open and close by the hydraulic device. A cylinder 6 is penetrated and fixedly connected to the middle of the cylinder cover 5, and a downward pressure device is fixedly connected to the output end of the cylinder 6, and a vertical downward pressure is generated on the medical waste in the sterilization cylinder 1 through the downward pressure device. One side of the sterilization cylinder 1 is connected to the water supply device through the water inlet pipe 7, and the other side is connected to the air inlet end of the filter device 9 through the exhaust pipe 8, and the top air outlet end of the filter device 9 is connected to the suction pump 10.

[0029] First, the sealed waste bag is unloaded into the treatment sterilization cylinder 1, without pre-sorting operation, crushing, etc. When the waste bag is unloaded, the cylinder cover 5 is closed. The rotary cutter 4 located at the bottom of the sterilization cylinder 1 starts to start. The waste will be crushed immediately (the fastest speed of the wheel is 1000 rpm). Due to the rotation of the rotary cutter 4 and the heat energy generated by the violent stirring and friction of the waste, the waste is heated to the program-set temperature of 138°C to 155°C. During this cycle, water is injected in a controlled manner. The water is fully in contact with the surface of the high-temperature treatment object and the evaporation, producing the same effect as wet heating disinfection. The changes that occur inside can be compared to the reaction observed when water falls on a continuously high-temperature surface such as an oven plate or an iron. The contact surface of the waste has the characteristics of high temperature, liquid water and steam at the same time. Since the cutting knife of the rotary cutter 4 has fully mixed and crushed the waste, each part of the waste enjoys the same treatment conditions, and the intervention of water and the measurement of temperature are determined in real time by the infrared rays released by the raw materials. Therefore, the entire treatment process is highly safe and reliable, and the treatment process is highly controllable. The treated dry material is automatically unloaded, and the treated medical waste is non-toxic general solid waste, which can be used as fuel for incineration and power generation. The water vapor distilled during the treatment process is filtered and cooled by the filter device 9 and then discharged to the sewage treatment system for pre-treatment and reuse in production.

[0030] By setting the driving device, the driving device drives the rotary cutter 4 to rotate, and the medical waste in the sterilization cylinder 1 is peeled and stirred, and the rotation speed difference between the rotary cutter 4 and the medical waste is continuously generated, thereby increasing the friction between the rotary cutter 4 and the medical waste, so that the temperature of the medical waste rises rapidly with the high-speed peeling of the medical waste by the rotary cutter 4, and at the same time, the efficiency of the rotary cutter 4 disturbing the medical waste is also improved, and the uniformity of the distribution of the medical waste in the sterilization cylinder 1 is improved, thereby greatly improving the treatment efficiency of the medical waste. Secondly, by setting the down-pressing device, the medical waste is subjected to the vertical down-pressure generated by the down-pressing device, thereby increasing the interaction force between the medical waste and the rotary cutter 4 on the one hand, and increasing the friction between the two, and on the other hand, the actual treatment space is reduced to the maximum, so that the heat generated by friction can be gathered in a smaller space, accelerating the efficiency and effect of the temperature rise. At the same time, after the water is injected, the hot steam generated is limited by the down-pressing device, thereby increasing the air pressure in the treatment space to increase the boiling point of water, thereby increasing the upper limit of the sterilization temperature.

[0031] The water supply equipment includes a quantitative water supply device and an infrared detector, wherein the infrared detector is arranged in the sterilization cylinder 1 to detect the temperature of the medical waste, and the water outlet end of the quantitative water supply device is connected to one end of the water inlet pipe 7. When the infrared detector detects that the temperature of the medical waste reaches a preset temperature, the quantitative water supply device inputs a preset amount of water into the sterilization cylinder 1 through the water inlet pipe 7.

[0032] The filtering device 9 includes a filtering tower 901, the air inlet end of the filtering tower 901 is connected to the exhaust end of the sterilizing cylinder 1 through the exhaust pipe 8, and the middle part of the filtering tower 901 is filled with a condensation filler 902. When the exhaust gas from the sterilizing cylinder 1 enters the filtering tower 901 under the action of the vacuum pump 10, harmful substances in the gas are absorbed and filtered by the condensation filler 902, and the water in the gas is absorbed by the condensation filler 902, and a condensation effect is produced, so that the water is liquefied and drips to the bottom of the filtering tower 901 and discharged, and then discharged to the sewage treatment system for pretreatment and reuse in production. The filtered clean gas moves from the top air outlet end of the filtering device 9 to the vacuum pump 10 for discharge, passes through the condensation filler 902 to remove a small amount of acidic gas, and then filters out possible bacteria that have not been inactivated and have been inactivated, and finally adsorbs to remove volatile organic compounds (VOCs) and odor in the exhaust gas.

[0033] The pressing device includes a pressure plate 11, a through hole 1101 is provided in the middle of the pressure plate 11, a slide bar 12 is fixedly connected to the upper surface, the slide bar 12 penetrates and is slidably connected to a mounting plate 13, the middle of the mounting plate 13 is fixedly connected to the output end of the cylinder 6, a limit block 1201 is fixedly connected to the top of the slide bar 12, a spring 14 is provided between the lower surface of the limit block 1201 and the upper surface of the mounting plate 13, and the spring 14 is sleeved on the rod body of the slide bar 12. The lower surface of the pressure plate 11 is a positive conical upper concave surface, and the upper surface is an inverted conical lower concave surface, and the surface of the positive conical upper concave surface is provided with uniformly distributed friction lines.

[0034] According to the actual amount of medical waste to be processed, the height of the pressure plate 11 is adjusted by the cylinder 6, so that the medical waste is subjected to the pressure of the pressure plate 11 and the smallest processing space is formed. On the one hand, the interaction force between the medical waste and the rotating cutter 4 is increased, and the friction between the two is improved. On the other hand, the actual processing space is reduced to the maximum extent, so that the heat generated by friction can be concentrated in a smaller space, accelerating the efficiency and effect of temperature rise. At the same time, after water is injected, the hot steam generated is limited by the downward pressure device, thereby increasing the air pressure in the processing space to increase the boiling point of water, thereby increasing the upper limit of the sterilization temperature.

[0035] This embodiment also provides a technical solution for a processing device, that is, the processing device also includes a controller, which controls the operating state of the driving device according to the load torque at the output end of the driving device detected by the controller. When the load torque is higher than a preset value, the controller controls the driving device to continue to rotate at a uniform speed, and when the load torque is lower than the preset value, the controller controls the driving device to change the speed or reverse. The driving device includes a motor 15, the output end of the motor 15 is fixedly connected to the shaft end of the rotating tool 4, and the outer wall of the motor 15 is fixedly connected to the bracket 3.

[0036] The load torque at the output end of the driving device detected by the controller controls the running state of the motor 15. When the load torque is higher than the preset value, the controller controls the motor 15 to rotate continuously at a constant speed. When the load torque is lower than the preset value, the controller controls the motor 15 to change the speed or reverse. This causes a speed difference or direct reverse movement between the rotating cutter 4 and the medical waste, thereby increasing the interaction force between the rotating cutter 4 and the medical waste, thereby increasing the effect of frictional heat generation.

[0037] Please see attached Figure 5 -Attached Figure 6 Based on the above embodiment, this embodiment provides another technical solution of a processing device, namely:

[0038] The sterilization cylinder 1 includes an upper cylinder 101 and a lower cylinder 102, which are rotatably connected to each other. The outer wall of the upper cylinder 101 is fixedly connected to the fixed frame 2, and the center of the bottom wall of the lower cylinder 102 is fixedly connected to a gear 16. The tooth end of the gear 16 is meshed with a gear 2 17. The middle part of the gear 2 17 is fixedly connected to one end of a driving shaft 18. The outer wall of the driving shaft 18 passes through and is rotatably connected to the rod body of the bracket 3. The inner wall of the lower cylinder 102 is also provided with evenly distributed friction patterns.

[0039] The driving device includes a motor 2 19, the output end of the motor 2 19 is fixedly connected to the shaft end of the rotating tool 4, and a gear 3 20 is also sleeved and fixedly connected to the outer wall of the shaft end, the tooth end of the gear 3 20 is meshingly connected to a gear 4 21, and the middle part of the gear 4 21 is fixedly connected to the other end of the driving shaft 18.

[0040] While driving the rotating cutter 4 to rotate, the motor 2 19 also drives the lower cylinder 102 to rotate in the opposite direction, so that the medical waste is simultaneously subjected to the cutting and stirring action of the rotating cutter 4 and the reverse driving force of the lower cylinder 102. Under the joint action of these two forces, there is always a speed difference and reverse rotation between the rotating cutter 4 and the medical waste, thereby increasing the interaction force between the rotating cutter 4 and the medical waste, thereby increasing the effect of frictional heat generation.

[0041] Embodiment three:

[0042] Please see attached Figure 7 Based on the above embodiment, this embodiment provides another technical solution of a processing device, namely:

[0043] The driving device includes a CVT gearbox 22, the outer wall of the CVT gearbox 22 is fixedly connected to the bracket 3, the input end of the CVT gearbox 22 is fixedly connected to the motor 3 23, one output end of the CVT gearbox 22 is fixedly connected to the shaft end of the rotating tool 4, and the other output end is fixedly connected to the other end of the driving shaft 18.

[0044] While driving the rotary cutter 4 to rotate, the motor three 23 also drives the lower cylinder 102 to rotate in the opposite direction. At the same time, by utilizing the characteristics of the CVT gearbox 22, the speed difference between the rotary cutter 4 and the driving lower cylinder 102 can be quickly and continuously changed, thereby making the speed difference between the rotary cutter 4 and the medical waste constantly change, further enhancing the effect of frictional heat generation, and further improving the uniformity of cutting of medical waste.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
