Description

[0001]
[Technical field to which the invention belongs]
The present invention sterilizes infectious wastes such as used bandages, cotton wool, syringes and infusion devices discharged from medical institutions such as clinics and hospitals, and generates substances that can be processed as general industrial waste. The present invention relates to a processing method and a processing apparatus.
[0002]
[Prior art]
Conventionally, from medical institutions, paper products (paper diapers), cloth products (bandages, cotton wool), plastic products (drip devices), glass products (syringes), metal products (injection needles), rubber products (tubes, gloves), etc. Many infectious wastes made of materials were discharged, and these wastes were managed separately from general industrial wastes as specially managed wastes.
[0003]
Infectious waste was incinerated mainly in incinerators, but it became a social problem because dioxins generated from incinerators adversely affected the surrounding environment and health. Medical institutions such as large hospitals have their own incinerators to incinerate infectious waste, or have asked specific contractors to dispose of them, but incinerate as before due to dioxin problems However, incineration was performed so that dioxins were not generated, so that the processing efficiency was low, the processing cost was increased, and the economic burden was increased. In addition, the contractors who undertook disposal often dumped illegally without incineration, causing new social problems.
[0004]
For this reason, in order to sterilize and dispose of infectious waste, for example, a sterilization treatment technique disclosed in JP-A-11-276534 and JP-A-2001-137315 is provided. In these known techniques, infectious waste is sterilized by heating under non-combustible gas with a single apparatus, cooled, pulverized, and taken out of the treated product in a detoxified state.
[0005]
[Problems to be solved by the invention]
In such an apparatus called a batch type, since there is a heat sterilization section, a cooling section, and a crusher in one apparatus, there is a limit to the amount of processing at one time and continuous processing cannot be performed. It was a thing. Moreover, it is necessary to heat the inside of the apparatus every time the waste is processed, and much more heat is required than the amount of heat for heating the processed material. This is the same even when cooling. In general, the batch system is inferior in energy efficiency, has a long processing time, and is inefficient in economic efficiency.
[0006]
And since the heater was arrange | positioned as a heat source in the ceiling part (upper part of an apparatus), it was not able to fully heat to the downward direction of waste, and the sterilization efficiency was bad. In particular, even when a bandage or gauze hardened with medicine or blood was heated, it could not be heat-treated to the inside, and a sufficient sterilizing effect could not be obtained. Furthermore, since water vapor and heated gas stains from the processed material adhere to the heater, regular cleaning is required.
[0007]
Moreover, conventionally, waste is stored in a special bag and sterilized by heating, so it takes time to heat the inside of the bag, and when it contains water such as blood and chemicals, the water evaporates. It was difficult and the sterilization effect was bad. Moreover, since the heating unit and the cooling unit are provided in one apparatus, it is necessary to make the structure not causing heat interference, and the structure is complicated.
[0008]
In the present invention, in view of the above-described conventional processing technology, a large amount of infectious waste can be sterilized efficiently and continuously, and the amount can be reduced and a general industrial waste disposal contractor can incinerate or landfill. It is an object of the present invention to provide an infectious waste treatment method and apparatus for forming a possible substance.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows the entire apparatus showing an embodiment of the present invention, and FIG. 2 shows an enlarged part of the apparatus. The present invention includes a crushing process, a heat sterilization process, a cooling process, and a compression process. Through this process, a substance capable of treating infectious waste as general industrial waste is generated.
[0013]
That is, the device of the present invention is composed of a crushing chamber 1, a crushing material leveling chamber 2, a regulating chamber 3, a heating sterilizing chamber 4, a regulating chamber 5, a cooling chamber 6 and a compression chamber 7. 1-7 are connected so that a series of processes can be performed continuously, and a shutter (or gate) 8 is installed between the chambers 1-7.
[0014]
Next, each chamber 1-7 is demonstrated.
The crushing chamber 1 is installed to crush infectious wastes finely before heat sterilization. In the crushing chamber 1, stainless steel placed on a transfer body 10 such as a crusher 9 and a chain conveyor is installed. A metal tray 11 such as aluminum is installed.
[0015]
The infectious waste A before being crushed is continuously sent by, for example, a belt conveyor or a roller conveyor in a state of being packed in a paper bag, a cloth bag, a cardboard box or the like, and is put into the crushing chamber 1. As shown in FIGS. 3 and 4, the crusher 9 includes a biaxial or triaxial rotary roller 12, and crushing blades that alternately mesh with each other are formed on the peripheral surface of each roller 12. Each roller 12 rotates in a meshing direction using a motor as a driving source, crushes waste A input from above through an inclined guide plate, and drops it by its own weight onto a tray 11 installed below. Is.
[0016]
A known crushing roller can be used as the crushing machine 9, but the crushing machine 9 is not limited to the roller, and other crushing machines 9 may be used. If the waste A can be crushed finely, its mechanism is not questioned. Absent. During crushing, high temperature steam may be jetted and supplied into the room to perform sterilization, and at the same time, odor generated in the room may be sucked by a deodorizing device (not shown).
[0017]
When a predetermined amount, for example, 480 liters of crushed material (hereinafter referred to as waste B) is placed on the tray 11, the shutter 8 is opened and the tray 11 is leveled by the transfer body 10. Feed into chamber 2. Since the transfer body 10 is installed in each of the chambers 1 to 7, the tray 11 can be fed from the front chamber to the next chamber in a horizontal state and taken in.
[0018]
When the tray 11 is placed in the leveling chamber 2, the shutter 8 is closed. Therefore, the dust and odor of the waste B generated in the crushing chamber 1 are not released to the outside.
The waste B finely crushed in the crushing chamber 2 is formed in a mountain shape on the tray 11 as shown in FIG. 5 and FIG. Absent. For this reason, it is necessary to level the upper surface of the waste B flatly, and a leveling machine 13 is installed in the upper part of the leveling chamber 2.
[0019]
The leveling machine 13 is configured to move the long plate-shaped scraper 14 in the vertical direction and the horizontal direction. In order to move the scraper 14 in the vertical direction, for example, a cylinder 15 and a pair of guide bars 16 on both sides are used, and in order to move in the horizontal direction, a pair of chains 17 circulated by a motor capable of forward and reverse rotation (not shown) is used. used.
[0020]
The chain 17 is stretched between the sprockets 18 and is located above the length of the tray 11, and a long moving member 19 is connected between the chains 17. That is, both ends of the moving member 19 and the upper part of the chain 15 are connected, and if the chain 15 is driven to the right in FIG. 5 by motor driving, the moving member 19 also moves, and when it approaches the sprocket 18a located on the right side, For example, the position detection sensor detects the moving member 19 and stops the motor. Next, when the chain 15 is caused to travel in the reverse direction, the moving member 19 returns to the original position.
[0021]
The cylinder 15 is installed above the moving member 19, and a cylinder rod passes through the moving member 19 and is connected to the scraper 14. Further, the lower portions of the two guide bars 16 pass through the moving member 19 and are connected to the scraper 14. The scraper 14 is guided by the guide bar 16 and moves up and down by driving the cylinder 15.
[0022]
The scraper 14 is normally positioned on one side of the tray 11 as shown in FIG. When the tray 11 is placed on the transfer body 10 in the leveling chamber 2, the scraper 14 is lowered by the cylinder 15.
At this time, if the lower end of the scraper 14 is stopped at the height of X and moved to the right, the upper part of the waste B can be cut down. Next, if the lower end of the scraper 14 is lowered to the Y position, the chain 17 is reversed and the scraper 14 is moved to the left, the upper surface of the waste B can be leveled. In addition, if it is not possible to equalize by one round trip, it is sufficient to make a round trip several times at the height of Y. Further, in FIG. 5, a pair of scrapers 14 may be installed on the left and right, and the scrapers 14 may be reciprocated alternately.
[0023]
When the leveling operation is completed as described above, the shutter 8 between the adjacent adjustment chambers 3 is opened and the tray 11 is sent into the adjustment chamber 3. When the tray 11 is placed in the adjustment chamber 3, the front shutter 8 is closed, the rear shutter 8 is opened, and the tray 11 is sent into the heat sterilization chamber 4. Due to the presence of the adjustment chamber 3, heat, gas, and the like in the heat sterilization chamber 4 do not flow out. The leveling chamber 2 and the heat sterilization chamber 4 may be connected via the shutter 8 without providing the adjustment chamber 3.
[0024]
When the shutter 8 is opened, high heat in the heat sterilization chamber 4 enters the adjustment chamber 3, and the heat generated in the waste B is not ignited by this heat. Active gas may be sent in and deodorizing treatment may be performed at the same time. This is the same when the leveling chamber 2 and the heat sterilization chamber 4 are directly connected.
[0025]
The heat sterilization chamber 4 heats the finely crushed waste B on the tray 11 to perform sterilization treatment. The heating sterilization chamber 4 is a long body and the transport body 10 is also a long body, and the transport body 10 is intermittently traveled at a constant distance every predetermined time. In the present invention, a far-infrared heater is used as a heating source, and five heaters 20 are installed at intervals determined along the transfer direction of the tray 11 between the transfer bodies 10.
[0026]
The tray 11 is intermittently transferred by the transfer body 10 at intervals of the heater 20 and placed on the heater 20, and is heated for a predetermined time from below. In the present invention, the tray 10 is transferred between the heaters 15 in units of 12 minutes. Therefore, in the heat sterilization chamber 4, one tray 11 is heated for 60 minutes.
[0027]
Further, the heating temperature is in the range of 180 ° C. to 200 ° C. Dioxins are not generated, and sufficient heating can be obtained. The heating time, heating temperature, etc. are determined by the properties of the waste B. In addition, when 480 liters of crushed waste B is placed on one tray 11 and heated as described above, since five trays 11 are installed in the heating sterilization chamber 4, a large amount of 2400 liters is provided. The waste B is heated and sterilized at a time.
[0028]
A fan 21 is installed in the heating sterilization chamber 4 above. The tray 11 is directly heated by the heater 20, and at the same time, the waste B is also heated and sterilized. However, since the hot air rises, the fan 21 is rotated to return the hot air to the room, and the waste B Are heated on average. A plurality of fans 21 may be installed in the heat sterilization chamber 4, or two or three fans 21 may be installed only in a part of the heat sterilization chamber 4, for example, the first half.
[0029]
Since the waste B is heated at a high temperature, an inert gas such as nitrogen gas is supplied to the heated sterilization chamber 4 so that ignited materials such as cloth and plastic products do not ignite. The overall structure is explosion-proof. And deodorizing in the heating sterilization chamber 4 is performed regularly or using the above-described deodorizing apparatus as needed, but at the same time, water vapor generated in the heating sterilization chamber 4 is also sucked.
[0030]
After the waste B is heated and sterilized as described above, the rear shutter 8 is opened, the tray 11 is sent to the adjustment chamber 5, the shutter 8 is closed, and the shutter 8 with the cooling chamber 6 is opened. The heated tray 11 is sent to the cooling chamber 6. The hot air in the heat sterilization chamber 4 and the cold air in the cooling chamber 6 are blocked by the presence of the adjustment chamber 5, so that the hot air and cold air do not interfere with each other.
[0031]
In the cooling chamber 6, the waste B is cooled. In order to cool the waste B, for example, air cooled by a cooling device installed outside the cooling chamber 6 is directly fed into the cooling chamber 6 and circulated, or cold air is introduced into the cooling chamber 6 through a pipe. It should circulate. Alternatively, the cooling water cooled by the outdoor cooling device may be circulated through the piping in the cooling chamber 6 to cool the entire cooling chamber 6 to cool the waste B. Whether to use cold air or to use cooling water can be arbitrarily selected. The cooling time is 10 to 12 minutes, and cooling is performed to a temperature of 90 to 110 ° C. The cooling time, cooling temperature, and the like can be selected depending on the heating temperature and the properties of the waste B. In addition, you may perform a deodorizing process also during cooling.
[0032]
The tray 11 that has been cooled is sent to the compression chamber 7 through the opened shutter 8 and is pressed into a small lump. However, since the waste B is solidified to some extent due to the evaporation of water by heating, it is necessary to scrape the waste from the tray 11. Therefore, the tray 11 is lifted in an oblique state using a lifting mechanism such as a known lifter. A scraping mechanism 22 is installed facing the ascending stop position of the tray 11.
[0033]
As shown in FIGS. 7 and 8, the scraping mechanism 22 has a plurality of scraping members 24 installed in a rectangular machine body 23, and moves the scraping member 24 up and down and pivots in the front-rear direction. The waste B is dropped obliquely downward without being scattered.
[0034]
The scraping member 24 connects the upper and lower sides of a pair of arms 25 installed symmetrically on both sides in the machine body 23, and the intermediate portion of each arm 25 projects to the peripheral end of the rotating plate 26 as shown in FIG. 9. A pin 28 projecting from the machine body 23 is inserted into a long hole 27 formed in the upper part of the arm 25 while being rotatably connected to the provided pin 26.
[0035]
If the rotating plate 26 is continuously rotated counterclockwise in the figure, the arm 25 moves up and down along the long hole 27 and the lower portion of the arm 25 rotates in the front-rear direction. Each arm 25 has a different protrusion length and rotation width with respect to the tray 11, so that each arm 25 operates differently and scrapes the crushed waste B in the tray 11 in an oblique manner. It will be.
[0036]
If a plate-shaped or bar-shaped scraping tool 29 is provided between the lower portions of the arms 25, each scraping member 24 is lowered toward the tray 11 and pushes the waste B by moving forward. By operating the scraping member 24, the waste B can be easily scraped across the entire surface of the tray 11. Although not shown, if the sprockets provided on the rotating shaft 30 of each rotating plate 26 are connected by a chain circulating by a motor, all the rotating plates 26 can be rotated in synchronization.
[0037]
The rectangular body 23 is divided into upper and lower parts, the upper body 23a is fixed, the lower body 23b is movable by cylinders 31 connected to both sides of the upper body 23a, and each arm 25 is installed on the lower body 23b. Then, the relative position of each arm 25 with respect to the tray 11 can be adjusted, and all the waste B in the tray 11 can be scraped out effectively. In the figure, reference numeral 32 denotes a guide bar for guiding the movement of the lower machine body 23b.
[0038]
The waste B that has been scraped off from the tray 11 and is in a separated state is put into the compressor 33 as it is.
The compressor 33 presses and solidifies the crushed, heated and sterilized waste B to form a small lump. As shown in FIGS. 10 and 11, the compression chamber 34 and the compression chamber 34 are And a compression member 35 that operates up and down, and compression members 36 and 37 that operate horizontally from both sides with respect to the compression chamber 34.
[0039]
The compression member 35 is accommodated in a rectangular support frame 38 erected above the compression chamber 34, and is moved up and down by a pair of cylinders 39 installed on both side surfaces of the support frame 38. An inclined guide plate 40 for waste B is provided on the lower side surface of the support frame 38, and the waste B scraped from the tray 11 is put into the compression chamber 34 through the guide plate 40.
[0040]
As shown in FIG. 12, a corrugated plate 41 is laid horizontally at the bottom of the compression chamber 34, and the waste B is placed on the plate 41.
When the compression member 35 is lowered by the cylinder 39, the waste B on the plate body 41 is crushed between the valley portions 42 of the plate body 41 by the weight of the compression member 35 (see FIG. 13). FIG. 13 shows a schematic configuration of compression from the top and bottom and the left and right for the waste B on the plate body 41.
[0041]
The compression member 36 is composed of a plurality of thrust bars 43 provided horizontally facing the respective valley portions 42 of the plate body 41, and the base portion of each thrust bar 43 is fixed to one moving body 44 and moved. The body 44 is reciprocated by a cylinder 45. If the thrust bar 43 is moved forward, it enters the trough 42 and moves in the direction in which the waste B in the trough 42 is compressed.
[0042]
Further, the compression member 37 is installed symmetrically with respect to the compression member 36 with the compression chamber 34 therebetween, and faces the trough portion 42 of the plate body 41 as shown in FIGS. 10, 11 and 14. And a plurality of compression holes 46 opened and cylinders 47 installed facing the respective compression holes 46.
[0043]
As described above, the compression member 35 is lowered to compress the fine waste B into the valley 42 of the plate body 41, and then the thrust bar 43 is advanced to form the waste B in the valley 42 on the compression member 37. Push into the compression hole 46. At the same time, when the cylinder 47 is actuated and the cylinder rod is pushed into the compression hole 46 from the opposite side, the waste B is crushed between the thrust bar 43 and the rod and compressed into a small lump in the compression hole 46. When the waste B is compressed by the push rod 43 and the rod, the compression member 35 may be kept lowered or may be raised to a predetermined position.
[0044]
After the waste B is compressed into a small lump in the compression hole 46 as described above, the thrust bar 43 and the rod of the cylinder 47 are returned to predetermined positions. And although the compression thing in the compression hole 46 is taken out outside, it can take out easily by connecting the compression member 37 to the fixing member 48 installed in the compressor 33 so that rotation is possible.
[0045]
The fixing member 48 is obtained by horizontally projecting connecting plates 50 on both sides of a long fixing plate 49. As shown in FIG. 14, rotating shafts 51 projecting on both sides of the compression member 37 are shown in FIG. As shown in FIG. 3, the coupling plate 50 is rotatably fitted in a horizontally long coupling hole 52 formed in the coupling plate 50. In addition, a rotation guide shaft 53 provided in parallel with the rotation shaft 51 passes through a downwardly curved guide groove 54 formed in the connecting plate 50, and the guide shaft 53 is parallel to the outside of the connecting plate 50. The slide plate 55 is connected to the slide plate 55.
[0046]
As shown in FIGS. 17, 18, and 19, the slide plate 55 has guide grooves 56 formed in parallel on the upper and lower surfaces of the inner surface, and longitudinal slide grooves 57 are formed between the guide grooves 56. In other words, the tip of the rotation guide shaft 53 is located in the sliding groove 57. The guide groove 56 is fitted to a guide bar 58 fixed to the outer surface of the connecting plate 50 and can be moved back and forth, and the fixed portion 59 of the slide plate 55 has a rod of a cylinder 60 whose base is fixed to the fixed plate 49. Since the tip of 61 is connected, the slide plate 55 does not come off the connection plate 50.
[0047]
Normally, the slide plate 55 is pushed forward by the cylinder 60, that is, toward the compression chamber 33. When the compression operation is completed in the compression hole 46 as described above, if the cylinder 60 is operated and the slide plate 55 is pulled, the rotation guide shaft 53 is pulled backward by the sliding groove 57, so that the compression member 37 also moves simultaneously. Will do. When a certain distance, that is, the length interval of the connecting hole 52 is moved, the rotation shaft 51 hits the rear end of the connecting hole 52 so that the compression member 37 does not retreat further.
[0048]
In this state, if the slide plate 55 is further retracted, the rotation guide shaft 53 comes into contact with the side surface of the slide groove 57, so that it is aligned with the longitudinal direction of the slide groove 57 and formed on the connecting plate 50. Since it moves in the bending direction along the guide groove 54, the compression member 37 rotates around the rotation shaft 51. Therefore, since the compression hole 46 of the compression member 37 faces downward, the compressed material accommodated inside is naturally discharged. If the discharge is difficult, the cylinder 47 may be operated to forcibly discharge.
[0049]
If the slide plate 55 is advanced by the cylinder 60 after the compressed material is discharged from the compression hole 46, the rotation guide shaft 53 is pushed by the side surface of the slide groove 57, so that it rises along the curved guide groove 54, The compression member 37 returns to the horizontal state. Therefore, the length of the sliding groove 57 is equal to or longer than the height of the guide groove 54.
[0050]
Turning the compression member 37 to discharge the compressed material in the compression hole 46 is not limited to the above structure, and other means may be used. For example, the compression member 37 may be rotatably connected to the connecting plate 50 by the rotation shaft 51, and the fixing plate 49 or the connecting plate 50 and the compression member 37 may be appropriately fixed by a stopper. After forming the compressed material therein, the stopper may be released and the compression member 37 may be manually rotated.
[0051]
All the operations of each process, such as crushing, leveling, heating, cooling, compression, etc., of the above-mentioned waste can be managed continuously by a computer, making a large amount of waste harmless. Can be discharged.
[0052]
【The invention's effect】
As described above, in the present invention, since the infectious waste is finely crushed in advance and made uniform on the tray 11 and then heated in the heat sterilization chamber 4, the surface area of the waste is increased. Since it becomes large and heats efficiently, the sterilization effect is high. Since the metal tray 11 is placed on the heater 20 in the heat sterilization chamber 4, the waste B is directly heated through the tray 11, so that the heat efficiency is good and the dioxin is adjusted by adjusting the temperature. Can be prevented.
[0053]
The cooled waste B can be scraped from the tray 11 and sent to the compressor 22 and compressed in the compression chamber 34 from the top and bottom and from the left and right to form a small lump. And post-processing can be performed efficiently. Moreover, since the compressed product can be processed as general industrial waste by sterilizing, the industrial waste manager can incinerate or landfill.
[0054]
The chambers 1 to 7 for treating waste are independent from each other, and a shutter 8 is installed between the chambers 1 to 7, so that dust, hot air, cold air, The generated odor is not released to the outside. In particular, since the heating sterilization chamber 4 and the cooling chamber 6 are installed separately, the temperatures in the heating sterilization chamber 4 and the cooling chamber 6 can always be kept constant without interfering with each other. Therefore, temperature management is easy and cost reduction can be achieved. And it does not adversely affect the surrounding environment and does not impair the health of workers.
[0055]
Furthermore, since a large amount of infectious waste can be continuously sterilized in the present invention, the cost can be reduced, and expenses such as university hospitals and general hospitals that discharge a large amount of infectious waste can be achieved. It is useful for saving.
