Description

Technical Field

[0001] The invention relates to a harmless treatment device for human tissue waste, belonging to the technical field of harmless treatment of medical waste. Background Art

[0002] Medical institutions often generate human tissue waste during surgical operations, pathological examinations, autopsies, and medical research. These wastes include removed organs, tissue specimens, pathological samples, etc., which may contain various pathogenic microorganisms, such as bacteria, viruses, fungi, etc., especially in the treatment of surgical resections of infectious patients, waste may become the source of pathogen transmission. Therefore, the disposal of human tissue waste must be very cautious to avoid major risks to public health and the environment. At present, the treatment of human tissue waste mainly relies on technical means such as high-temperature incineration and steam disinfection and sterilization. Among them, high-temperature incineration is the most common treatment method. By thoroughly incinerating at a high temperature of 800-1200°C, the pathogenic microorganisms and harmful substances can be effectively eliminated.

[0003] However, for a small amount of human tissue waste (for example, warts, tumors, blood clots, tissue samples and other human tissue), transporting it to a medical waste treatment center or incineration plant for incineration is costly and risky. On the one hand, the transportation cost may even be higher than the incineration cost; on the other hand, considering that there may be loopholes or human errors in the transportation and disposal process, the risk of contamination and transmission is increased.

[0004] For the small amount of human tissue waste generated during surgical operations and pathological examinations, some hospitals or medical institutions currently use high-temperature steam sterilizers for local processing, which are suitable for most pathological wastes, especially non-high-risk tissue samples. However, when high-temperature steam sterilizers process human tissue waste, due to the processing temperature below 150°C, there may be some infectious organisms that cannot be completely killed, especially pathogens with strong heat resistance, and conventional high-temperature steam sterilization processes may not be able to completely remove their infectiousness.

[0005] Therefore, a small-scale human tissue waste harmless treatment equipment was designed for local use in hospitals. It can initially chop the frozen human tissue waste, heat and incinerate it, and crush it to produce harmless solid ash. The waste gas generated in this process is absorbed by the waste gas treatment device and then discharged harmlessly. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a human tissue waste harmless treatment device, which solves the problem of lack of localized small-scale treatment equipment when performing harmless treatment of a small amount of human tissue waste.

[0035] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0036] The "up" and "down" mentioned in this article refer to the normal working state of the device. Figure 2 Above and below the device when placed on the ground as shown.

[0037] like Figure 1 , Figure 2 As shown, the device is used for local harmless treatment of a small amount of human tissue waste generated in the hospital, and comprises an incinerator 1, an incineration grinding component 2, and a thermal cycle crushing component 3.

[0038] like Figure 3 As shown, the incinerator 1 includes a furnace body 11 with an opening on the top, and a cover body 12 closing the opening of the furnace body 11. The opening of the furnace body 11 is fixed to the cover body 12 by screwing. The furnace body 11 and the cover body 12 use incineration silicon castables that can withstand high temperatures above 1200°C as inner core working layer materials, and use aluminum silicate fiber modules and aerogel composite insulation boards as outer insulation layer materials.

[0039] like Figure 3-Figure 6 As shown, in some embodiments, the incineration grinding assembly 2 includes a lower grinding disc 21 rotatably mounted at the bottom of the furnace body 11, a grinding drive mechanism 22 driving the lower grinding disc 21 to rotate, and an electric heating device 23 for heating the lower grinding disc 21. The metal grinding seat 2101 is made of a common high-temperature resistant metal material in the art, for example, the model is Incoloy 800H (austenitic heat-resistant alloy), which can remain stable in a high-temperature environment of 600-1100°C and has good anti-oxidation and corrosion resistance. Other metal materials in the art that can withstand high temperatures above 800°C and can be heated by electromagnetic heating can also be used. The electric heating device 23 uses an electromagnetic heating coil, which is fixed to the bottom of the furnace body 11 and is non-contactly sleeved outside the circumference of the metal grinding seat 2101. The electromagnetic heating coil is connected to a high-frequency current to heat the upper surface of the metal grinding seat 2101 to above 600°C, preferably 600-800°C. The temperature of the lower grinding disc 21 is detected by installing a first thermometer near the circumference of the metal grinding seat 2101.

[0040] The electromagnetic heating coil using high-frequency alternating current generates eddy currents inside the metal, thereby heating the metal grinding seat 2101. At this time, for the rotating metal grinding seat 2101, the ordinary heating method requires placing a heating device inside the metal grinding seat 2101, and the circuit and installation structure are relatively complicated. However, the non-contact electromagnetic heating coil method adopted in this solution is used for heating, and the metal grinding seat 2101 does not need to be in contact with the electric heating device 23, and the rotation of the metal grinding seat 2101 will not be blocked. It not only utilizes the characteristics of the electromagnetic heating coil with fast heating speed and high temperature, and can quickly transfer heat to the surface of the lower grinding disc 21, but also utilizes the heating characteristics of rotating metal objects to simplify the structural design. This is an effect that cannot be achieved by ordinary heating methods.

[0041] like Figure 3-Figure 6 As shown, in some embodiments, an upper ceramic grinding disc 25 is mounted on the upper part of the furnace body 11 through a plurality of suspension rods 24, and the lower grinding disc 21 includes a metal grinding seat 2101 and a lower ceramic grinding sheet 2102 fixed on the upper surface of the metal grinding seat 2101, and the upper ceramic grinding disc 25 is in close contact with the lower ceramic grinding sheet 2102. The contact surfaces of the upper ceramic grinding disc 25 and the lower ceramic grinding sheet 2102 are both provided with oblique groove patterns commonly used in the art, which is conducive to grinding and discharging the incoming objects.

[0042] The upper ceramic grinding disc 25 and the lower ceramic grinding disc 2102 are in close contact to incinerate and grind the human tissue waste that has been broken into small particles by the crushing blade 33. The current incinerators are large-scale equipment and are difficult to be arranged locally. The temperature of small incinerators is low, and it is difficult to incinerate or disinfect the inside of human tissue waste in a short time, which may result in incomplete internal incineration and still have the risk of transmission. This solution adopts crushing first, then grinding and high-temperature incineration at the same time, and repeats incineration-grinding-incineration. It has the advantages of low temperature requirements (600-800℃ on the upper surface of the lower grinding disc 21, and 400-600℃ in the upper furnace body 11), fast incineration speed, and thorough incineration. Specifically, the human tissue waste particles are crushed by the crushing blade 33 and then thrown into the vicinity of the conical hole 251. The conical hole 251, which is small at the top and large at the bottom, forms a gradually narrowing slope between the upper and lower contact surfaces of the upper ceramic grinding disc 25 and the lower ceramic grinding disc 2102. Under the action of rotating centrifugal force, the human tissue waste particles gradually enter between the upper ceramic grinding disc 25 and the lower ceramic grinding disc 2102. After being squeezed and ground by the inclined groove patterns on the surface, the human tissue waste particles are quickly crushed into layers, incinerated at high temperature, and then further crushed into powder. Finally, the ash after high-temperature combustion and grinding falls into the annular groove 2104 under the action of centrifugation.

[0043] like Figure 3-Figure 6 As shown, in some embodiments, the thermal cycle crushing assembly 3 includes a conical crushing barrel 31 whose bottom small end is fixed to the conical hole 251, the inner wall of the crushing barrel 31 is coated with a smooth ceramic coating to prevent human tissue waste from sticking, and a crushing motor 32 is sealed and fixed to the top of the cover body 12, the crushing motor 32 is installed outside the cover body 12, the rotating shaft of the crushing motor 32 passes through the cover body 12 through a packing dynamic sealing structure, a crushing blade 33 is fixed to the bottom end of the rotating shaft of the crushing motor 32, and a thermal cycle fan blade 34 is fixed to the upper part of the rotating shaft of the crushing motor 32, a plurality of circulating air flow holes 311 are evenly opened on the upper circumference of the crushing barrel 31, when the cover body 12 closes the top opening of the furnace body 11, the rotating shaft of the crushing motor 32 passes downward through the cover body 12 and extends to the bottom of the crushing barrel 31, at this time, the crushing blade 33 is located in the conical hole 251, and the thermal cycle fan blade 34 is located below the circulating air flow hole 311. The crushing blade 33 is placed at the bottom of the conical hole 251, and the outer diameter of the crushing blade 33 is slightly smaller than the inner diameter of the bottom of the conical hole 251 (the outer diameter of the crushing blade 33 is 0.1-0.5mm smaller than the inner diameter of the bottom of the conical hole 251). In this way, the crushing blade 33 can completely crush the frozen human tissue waste and play a role in cleaning the conical hole 251.

[0044] Before harmless treatment, the frozen human tissue waste is placed in the conical crushing cylinder 31, and then the cover 12 is closed. The crushing motor 32 is started, and the crushing blade 33 gradually breaks up the human tissue waste. The broken human tissue waste particles enter between the upper ceramic grinding disc 25 and the lower ceramic grinding disc 2102 under the action of centrifugation for grinding and high-temperature incineration.

[0045] At the same time, the heat circulation fan blades 34 blow the air flow inside the furnace body 11 downward and into the gap between the upper ceramic grinding disc 25 and the lower ceramic grinding disc 2102, so that oxygen is more sufficient and high-temperature incineration is faster. On the other hand, the internal high-temperature gas is circulated, and the high-temperature gas is used to preheat the human tissue waste that has not yet entered the gap. The high temperature at the bottom of the incinerator 1 can be sucked into the crushing cylinder 31, and then blown to the conical hole 251 after passing through the crushing cylinder 31, replenishing oxygen into the conical hole 251 and the gap between the upper ceramic grinding disc 25 and the lower ceramic grinding disc 2102, thereby accelerating incineration. At the same time, the internal high-temperature gas flow can also be used to disinfect and sterilize the inside of the incinerator 1.

[0046] The bottom of the crushing barrel 31 is fixed to the truncated cone hole 251. When the upper ceramic grinding disc 25 and the lower ceramic grinding disc 2102 are grinding, vibration will occur, and the vibration is transmitted to the crushing barrel 31. The material above is continuously fed to the bottom through the vibration of the crushing barrel 31. With the dual effects of the vibration effect of the crushing barrel 31 and the non-stick ceramic coating, the material is not prone to wall hanging.

[0047] like Figure 3-Figure 6 As shown, in some embodiments, the grinding drive mechanism 22 is composed of a driving shell 221, a connecting shaft 222, a grinding toothed disk 223, a grinding motor 224, and a driving tooth 225. The driving shell 221 is fixed under the furnace body 11, and the upper end of the connecting shaft 222 is fixed to the bottom center line of the metal grinding seat 2101. The lower end of the connecting shaft 222 passes through the furnace body 11 and extends into the driving shell 221. The connecting shaft 222 and the top and bottom of the driving shell 221 are movably installed by ceramic bearings 226 respectively. The grinding toothed disk 223 is located in the driving shell 221 and is fixed to the connecting shaft 222. The grinding motor 224 is fixed to the driving shell 221. The driving tooth 225 is fixed on the rotating shaft of the grinding motor 224, and the metal grinding seat 2101 is driven to rotate by the engagement of the driving tooth 225 with the grinding toothed disk 223.

[0048] A grinding motor 224, a driving tooth 225, and a grinding toothed disc 223 are arranged at the bottom of the furnace body 11 to amplify the decelerated motor torque and drive the lower grinding disc 21 to rotate, thereby improving the grinding effect.

[0049] like Figure 3-Figure 6As shown, in some embodiments, a raised disc portion 2103 is provided in the middle of the metal grinding seat 2101, and a circle of annular grooves 2104 for storing the discharged material are provided on the metal grinding seat 2101 around the raised disc portion 2103, and a ceramic grinding disc 2102 is installed on the top of the raised disc portion 2103.

[0050] The powdery ash formed after incineration and grinding will be difficult to clean if it falls directly into the furnace body 11, and continuous harmless treatment cannot be achieved. Therefore, an annular groove 2104 structure is used to collect the powdery ash so that it can be collected and cleaned in conjunction with the negative pressure suction component 4.

[0051] In the incinerator 1, the high temperature incineration of human tissue waste will not only produce solid incineration, but also produce toxic and harmful gases, which cannot be directly discharged into the air. Therefore, during the harmless treatment process, it is necessary to form a negative pressure environment in the incinerator 1 to extract and adsorb the harmful gases before discharging them.

[0052] Current vacuum cleaners cannot withstand high-temperature gases when sucking ash. Therefore, in order to be able to suck and collect the burned ash while also dealing with toxic and harmful gases generated by the internal high temperature, it is necessary to design a negative pressure suction component 4 that can cope with this.

[0053] like Figure 3-Figure 7 As shown, in some embodiments, a negative pressure suction assembly 4 is also fixed to one side of the incinerator 1, and the negative pressure suction assembly 4 includes an ash hopper 41, a discharge storage chamber 42, and an adsorption cylinder 43. The side of the ash hopper 41 is sealed with a suction pipe 44, and the lower end of the suction pipe 44 extends to the bottom of the annular groove 2104. The bottom of the ash hopper 41 is sealed with the discharge storage chamber 42, and the top of the ash hopper 41 is connected to the adsorption cylinder 43.

[0054] The suction pipe 44 is used to perform negative pressure suction on the inside of the incinerator 1. Under the effect of the negative pressure, the gaps of the incinerator 1 and other mechanisms that are not sealed during installation will not emit toxic and harmful gases to the outside.

[0055] In addition, during the incineration process of the incinerator 1, the temperature of the internal mixed gas is very high and cannot be directly adsorbed by the activated carbon, so a structure is designed to first cool down and then adsorb.

[0056] like Figure 7 As shown, in some embodiments, the adsorption cylinder 43 is sequentially provided with a water cooling chamber 4301, an adsorption chamber 4302, a fan chamber 4303, and an exhaust chamber 4304 from bottom to top, the water cooling chamber 4301 includes two upper and lower partitions 4305 sealed and fixed to the inner wall of the adsorption cylinder 43, a closed water cavity is formed between the two partitions 4305, and the upper and lower end surfaces of the two partitions 4305 are connected by a plurality of heat dissipation air pipes 4307, and the heat dissipation air pipes 4307 are densely packed with thin straight copper tubes ( Figure 7There are densely packed thin straight copper tubes in the middle to increase the heat exchange contact area), or bent thicker copper tubes (not shown in the figure, bending the copper tubes increases the heat exchange contact area and flow time), a metal filter screen 4306 is arranged under the bottom partition 4305 to prevent large particles from entering the cooling chamber and adsorption chamber 4302 above, and circulating water joints connected to the cooling water circulation pipeline are respectively arranged at the upper and lower parts of the closed water cavity. After the refrigerant is introduced, the gas flowing out from the upper partition 4305 is required to be cooled to below 60°C, and the exhaust gas after cooling is detected by installing a second thermometer under the activated carbon filter cover 4308. An activated carbon filter cover 4308 is provided on the top of the adsorption chamber 4302, and a suction duct 4309 connected to the fan chamber 4303 is provided inside the activated carbon filter cover 4308. A suction fan 4310 for sucking the airflow in the suction duct 4309 toward the exhaust chamber 4304 is provided in the fan chamber 4303. An exhaust port 4311 is provided on the top of the exhaust chamber 4304, and an activated carbon filter screen 4312 for filtering the airflow is provided between the air outlet of the fan chamber 4303 and the exhaust port 4311 of the exhaust chamber 4304.

[0057] The water cooling chamber 4301 is used to cool down the internal high-temperature gas, and the low-temperature toxic and harmful gases are easily adsorbed by the activated carbon filter 4312 and the activated carbon filter cover 4308, thereby improving the adsorption effect.

[0058] The suction fan 4310 has two power levels: large and small:

[0059] (1) When the suction fan 4310 is operating at a low power level, it can generate a negative pressure environment for preventing toxic and harmful gases from overflowing (the negative pressure value in the furnace body 11 is usually maintained between -10Pa and -60Pa).

[0060] (2) When the suction fan 4310 is operating at a high power level, it can not only generate a higher negative pressure, but also suck the ash at the bottom of the annular groove 2104 into the ash hopper 41 through the suction pipe 44, and drop it into the discharge storage chamber 42. The suction pipe 44 enters the interior from the tangential direction of the ash hopper 41, forming a cyclone separation effect, which is beneficial to the separation of gas and solid. The solid falls into the discharge storage chamber 42, and the gas enters the adsorption cylinder 43 from above the ash hopper 41.

[0061] The lower end of the suction pipe 44 is provided with a scraper that matches the cross section of the annular groove 2104. A gap of 1-3 mm is reserved between the scraper and the annular groove 2104, which can maintain a strong suction force and suck up the ash after incineration and grinding. The scraper is a scraper or a metal brush, which can clean the annular groove 2104.

[0062] like Figure 3As shown, in some embodiments, the suspension rod 24 includes a telescopic rod 241, a spring 242, a stopper 243, and a sleeve 244. The sleeve 244 is fixed to the upper part of the furnace body 11 through a support 245. The support 245 is a hollow steel plate fixed to the upper part of the furnace body 11. A hole is provided on the steel plate so as not to affect the upward circulation of the airflow below. The crushing cylinder 31 is located in the hole and is not fixed to the hole. When the crushing cylinder 31 vibrates up and down with the upper ceramic grinding disc 25, it is not hindered by the support 245. The bottom of the telescopic rod 241 is connected to the upper surface of the upper ceramic grinding disc 25. The upper end of the telescopic rod 241 passes through the sleeve 244 and is limited by the stopper 243. Grinding is achieved by the gravity of the upper ceramic grinding disc 25. A spring 242 for providing downward pressure can also be provided on the telescopic rod 241 between the sleeve 244 and the upper ceramic grinding disc 25 to further increase the grinding pressure.

[0063] The spring 242 can provide continuous downward pressure to the upper ceramic grinding disc 25 so as to grind and crush the particles. The telescopic rod 241 and the sleeve 244 cooperate to provide a stable upward and downward movement space, but will not rotate relative to the furnace body 11. During disassembly and assembly, the limit stopper 243 can prevent the upper ceramic grinding disc 25 from falling.

[0064] like Figure 5-Figure 6 As shown, in some embodiments, the lower ceramic grinding disc 2102 is composed of a circular grinding disc 2105, a plurality of bosses 2106 arranged at the bottom of the circular grinding disc 2105, and a central axis 2107 arranged on the center line of the bottom of the circular grinding disc 2105. The raised disc portion 2103 of the metal grinding seat 2101 is provided with a groove 2108 and a connecting hole 2109 respectively corresponding to the boss 2106 and the connecting shaft 222. There is a Hexagonal hole 2110, the upper end of the connecting shaft 222 adopts a hexagonal connector that matches the hexagonal hole 2110, and the lower ceramic grinding disc 2102 is placed on the raised disc portion 2103 of the metal grinding seat 2101. At this time, the boss 2106 matches the groove 2108, and the central axis 2107 is inserted into the connecting hole 2109. Expansion gaps are reserved between the boss 2106 and the groove 2108, and between the central axis 2107 and the connecting hole 2109 to prevent thermal expansion and contraction.

[0065] Since the expansion coefficients of ceramics and metals are different, if the two are fixed by screw connection or other methods, the lower ceramic grinding disc 2102 will break after the temperature changes. Therefore, the boss 2106 and the groove 2108 are used to transmit the rotation, and the central axis 2107 is used as the center for positioning. After heating and expansion, the central axis 2107 is made of ceramic material, which is always smaller than the expansion degree of the connecting hole 2109. The expansion and contraction gaps are reserved between the boss 2106 and the groove 2108, and between the central axis 2107 and the connecting hole 2109, which can further prevent the influence of thermal expansion and contraction on the ceramic material and prevent the ceramic from breaking. The expansion and contraction gap has little effect on the transmission between the slowly rotating metal grinding seat 2101 and the lower ceramic grinding disc 2102, and does not affect the normal grinding action.

[0066] like Figure 4 As shown, in some embodiments, a one-way air inlet valve 5 for introducing gas into the furnace body 11 is disposed on the cover body 12 .

[0067] In order to continue incineration, oxygen can be introduced into the furnace body 11 through the one-way air inlet valve 5 to accelerate the combustion and carbonization process of human tissue waste, making the incineration and disinfection more thorough. Air or compressed air can also be introduced when sucking the ash to ensure that the suction pipe 44 has enough suction force at the mouth.

[0068] Control principle: Start the negative pressure suction component 4, control the suction fan 4310 to run at a low power gear, and then form a diffusion-proof negative pressure environment in the furnace body 11; put the frozen human tissue waste into the crushing cylinder 31 of the incinerator 1, cover the cover 12, and tighten it with screws; start the electric heating device 23 to preheat the lower grinding disc 21 to 600-800℃ (observe the first thermometer reading); start the crushing motor 32 and the grinding motor 224 to crush and grind; when all the waste has been incinerated and ground After the ash is in powder form, the suction fan 4310 is controlled to run at a high power gear, the ash is adsorbed into the ash hopper 41, and the gas-solid separation is achieved through cyclone separation. The solid powder ash falls into the discharge storage chamber 42, and the gas is cooled to below 60°C (observe the second thermometer reading), and is filtered for the first time by the activated carbon filter cover 4308, and then filtered for the second time by the activated carbon filter screen 4312, and finally reaches the emission standard. The activated carbon filter cover 4308 and the activated carbon filter screen 4312 need to be replaced in time after saturation. The above process can be controlled manually, or the electronic components in this solution can be electrically connected to the controller to form a control circuit to achieve automatic control.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
