The present invention relates to a medical waste incineration processing apparatus, and more particularly, to a complex medical waste incineration processing apparatus that can select an input method of medical waste to an incinerator, thereby performing efficient and smooth incineration according to the environment. it's about

Medical wastes discharged from medical institutions such as hospitals and public health centers as well as nursing homes include, for example, disposable syringes, cotton or gauze for wiping blood or secretions, bandages, diapers after use, human extracts, surgical gloves, body fluids, and the like. Since almost all medical waste contains pathogens and has a risk of causing infection, it is necessary to prevent secondary and tertiary infections and block odors through thorough waste management.

The rough treatment process for medical waste is usually done as follows. First, a cleaner or a person in charge of sanitation in the area separates and collects medical waste by type, puts it in a designated box, seals it, and then writes the type of medical waste or related matters on the outside of the box and puts an electronic tag ( RFID) is attached. Upon completion of this process, boxes of medical waste are temporarily stored in, for example, isolated warehouses in the basement of the building.

Thereafter, the medical waste treatment company transports the medical waste stored in the underground warehouse to an incinerator or landfill after loading it in a vehicle for waste collection and incineration or landfill treatment.

There are batch type and continuous type for the input method of medical waste to the incinerator. The batch type is a method of putting medical waste into the hopper of the incinerator at once. For example, a predetermined amount of medical waste is injected over rounds (that is, round 1, round 2, round 3, etc.). In addition, the continuous method is a method in which medical waste is injected little by little but continuously. For example, medical waste is continuously fed one at a time at an interval of 1 second. The batch input method and the continuous input method have advantages and disadvantages, respectively, and are appropriately selected according to the amount of waste and treatment load.

1 is a view showing the overall configuration of a complex medical waste incineration treatment apparatus 10 according to an embodiment of the present invention.

As shown, the combined medical waste incineration processing apparatus 10 according to the present embodiment includes a sterilization unit 20, a transfer unit, a batch input unit 50, a path change unit 52, an extension conveyor 61, It includes a sequential input unit (70), a control unit (35).

The sterilization unit 20 serves to transport and sterilize the medical waste 100 brought in from the outside. Medical waste 100 consists of a sealed box 101 for packaging and an electronic tag (RFID) 103 . The sealed box 101 is sealed and accommodates various wastes (disposable syringes, cotton or gauze wiped with blood or secretions, bandages, diapers after use, human extracts, surgical gloves, bodily fluids, etc.) inside. The sealed box 101 is incinerated together with the waste inside. The electronic tag 103 is a general RFID, which allows the location of the medical waste 100 to be known from a remote location.

The sterilization unit 20 sterilizes the outer surface of the sealed box 101 . Since the outer surface of the sealed box 101 may be contaminated with bacteria during the process of transferring the medical waste 100 , sterilization is performed to prevent infection of workers located in subsequent lines.

The configuration of the sterilization unit 20 is separately illustrated in FIGS. 2 to 4 .

2 is a side view of the sterilization unit shown in FIG. 1, and FIG. 3 is a plan view of the transfer device 20A of FIG. In addition, FIG. 4 is a view separately showing the transfer wheel 23 shown in FIG. 2 .

As shown, the sterilizer 20 is composed of a transfer machine 20A and a sterilizer 20B. The transporter 20A transports the medical waste 100 , and the sterilizer 20B serves to irradiate the medical waste 100 during transport with sterilizing light, for example, ultraviolet sterilizing light.

The transporter 20A includes a housing 21 supported on a leg 21c, a plurality of wheel shafts 24, a dual sprocket 25, a chain 26, a driving motor 27, a transport wheel 23, A top plate 21a is provided.

The housing 21 takes the shape of a rectangular box extending along the transport direction of the medical waste 100 and provides an internal space 21e open to the top. The inner space 21e is covered by the upper plate 21a.

The upper plate 21a is a rectangular plate having a predetermined thickness, and has a plurality of wheel exposure holes 21b through which a transfer wheel 23, which will be described later, protrudes upward. A portion of the rotating transfer wheel 23 protrudes above the wheel exposure hole 21b. The transfer wheel 23 moves the medical waste 100 toward the alignment conveyor 31 while rotating in the arrow a direction.

The wheel shaft 24 is a shaft extending in a direction perpendicular to the transport direction of the medical waste 100 and axially rotatably supported at both ends by the housing 21 . The wheel shaft 24, within the limit of maintaining the parallel, and within the limit of exposing the transfer wheel 23 to the upper portion of the wheel exposure hole 21b, the spacing or height can be variously changed. For example, the height of each wheel shaft can be different or the distance can be changed.

The dual sprocket 25 is two sprockets joined side by side, fixed to one end of each wheel shaft 24 and located outside the housing 21 . In addition, the chain 26 is a transmission means for connecting the dual sprockets of the wheel shafts adjacent to each other. Since the dual sprocket 25 is connected by the chain 26, all the wheel shafts 24 simultaneously rotate in the same direction. The size of the dual sprocket 25 is the same.

In addition, the driving motor 27 has a driving sprocket 27a on the driving shaft as outputting rotational torque by receiving electric power applied from the outside. The driving sprocket 27a is connected to the leftmost dual sprocket 25 in the drawing through a chain 26 . According to the driving of the driving motor 27, all the wheel shafts 24 are axially rotated at the same time.

The transfer wheel 23 is fixed to the wheel shaft 24 and rotates in the direction of arrow a as shown in FIG. 2 , and receives the axial rotational force of the wheel shaft 24 to perform rolling motion to move the medical waste 100 to the right. serves to move to The transfer wheel 23 includes a hub 23a having a shaft hole 23b formed therein, and a friction tire 23d fixed to an outer circumferential surface of the hub. Of course, the wheel shaft 24 is fitted into the shaft hole 23b. The friction tire 23d has uneven portions 23e formed on its surface like a wheel of a motorcycle. The concave-convex portion 23e prevents the sealing box 101 from sliding with respect to the friction tire 23d.

Although all the feed wheels 23 applied to one feeder 20A may have the same diameter, preferably, feed wheels having various diameters may be mixed and used. For example, as shown in FIG. 2, a relatively small-diameter transfer wheel 23 is applied to the wheel shaft 24 of an odd-numbered row, and a relatively large-diameter transfer wheel 23 is mounted on the wheel shaft of an even-numbered row. will be. In addition, in some cases, the conveying wheels 23 having various diameters may be irregularly mixed and combined without distinction between odd rows and even rows.

In addition, a plurality of transfer wheels 23 fitted to one wheel shaft 24 are spaced apart from each other, and spaced apart from each other at intervals smaller than the length of the short side of the sealing box 101 . This is to prevent the sealing box 101 from falling between the transfer wheels 23 . Furthermore, the spacing of the wheel shafts 24 may be variously changed within the limit of maintaining parallelism. In other words, the spacing of the plurality of wheel shafts 24 is irregularly arranged.

In this way, by varying the diameter of the conveying wheel 23 and applying various spacing of the wheel shaft 24, the medical waste 100 during transportation may fluctuate greatly in front, back, left and right or, in some cases, to fall sideways or turn over. Thus, the sterilizing light can be irradiated to the entire surface of the sealed box (101).

The sterilizer 20B is installed on the upper part of the transporter 20A, and by irradiating sterilizing light to the outer surface of the medical waste 100 transported by the transport wheel 23, that is, the surface of the sealed box 101, infectious bacteria are removed. sterilize When the contents accommodated in the sealed box 101 are contaminated with infectious bacteria, the bacteria may have spread to the outside of the sealed box 101, so the sterilizer 20B is used to sterilize. The sterilizing light to be irradiated may be UV sterilizing light.

As mentioned above, in the subsequent line of the sterilization unit 20, since the operator who handles the medical waste 100 is disposed, the sterilization unit 20 is applied to prevent infection of the operator.

The description will be continued with reference to FIG. 1 again.

The medical waste 100 passing through the sterilization unit 20 slides on the swash plate 29 and is transferred to the transfer unit. The transfer unit includes an alignment conveyor 31 and an inclined conveyor 33 .

The alignment conveyor 31 serves to receive and horizontally transport the medical waste 100 that has been poured down on the inclined plate 29 . The operator arranged next to the alignment conveyor 31, but arranges the medical waste 100 on the alignment conveyor 31, in a line, and arranged to be spaced apart from the front and back. The inclined conveyor 33 receives the medical waste 100 passing through the alignment conveyor 11 and transports it upward.

At the upper end of the inclined conveyor 33 , a batch-type input unit 50 and a path change unit 52 are installed.

The batch-type input unit 50 receives the medical waste 100 delivered through the inclined conveyor 33 and puts it into the combustion chamber of the incinerator 40, the vertical chute 51, the weight sensing door 59b, the actuator (59a).

The vertical chute 51 has a hopper 51a at its upper end and a lower end connected to the combustion chamber, and provides a vertically extending vertical passage 51b. The medical waste that has fallen through the vertical passage 51b is combusted in the combustion chamber. Reference numeral 51f denotes a water jacket. The water jacket 51f cools the vertical chute 51 to prevent thermal deformation.

The weight sensing door 59b is installed inside the vertical chute, and once supports and supports the medical waste 100 that has passed downward through the hopper 51a, and opens at the moment when the total weight of the medical waste becomes heavier than the set value, the medical waste is discharged into the combustion chamber. It serves to make it fall. The weight sensing door 59b is opened and closed by a hydraulic actuator 59a. The actuator 59a operates by receiving an operation signal from the control unit 35 .

In addition, a weight sensor 59e is disposed under the weight sensing door 59b. The weight sensor 59e measures the magnitude of the load applied to the weight sensing door 59b and transmits it to the control unit 35 . The controller 35 operates the actuator 59a based on the load information received from the weight sensor 59e. A load cell may be used as the weight sensor 59e.

The path switching unit 52 is installed under the hopper 51a of the vertical chute 51, and whether the medical waste delivered from the inclined conveyor 33 directly falls to the weight sensing door 59b side, or outside the vertical chute. It serves to determine whether to take out with the extension conveyor (61).

FIG. 5 is a cutaway perspective view for explaining the path switching unit 52 , and FIGS. 6 and 7 are views for explaining the operation of the path switching unit 52 .

As shown, a square side passage 51d is formed on one side wall of the upper end of the vertical chute 51. The side passage (51d) is a passage through which the medical waste 100 put through the hopper (51a) is taken out in the direction of the arrow e of FIG.

The path switching unit 52 includes a path changing plate 53 , a shaft holder 53a , a support shaft 54 , a worm wheel 55 , a worm 57 , and a switching plate driving unit 56 .

The path switching plate 53 is a rectangular plate having a certain thickness, and is rotatably installed inside the vertical chute. As shown in FIGS. 6 and 7, the path switching plate 53 blocks the side passage 51d in a vertically erected state, or rotates downward to open the side passage 51d and at the same time downward toward the side passage. It provides a sloping slope. Depending on the position of the path switching plate 53, the medical waste 100 may be guided down to the vertical passage (51b) or the extended conveyor (61).

The shaft holder 53a is fixed to the lower end of the path switching plate 53 and passes the support shaft 54 horizontally. The support shaft 54 is coupled to the shaft holder 53a and transmits its own rotational force to the path switching plate 53 . The coupling between the support shaft 54 and the shaft holder 53a may be welded or bolted.

The support shaft 54 is supported so as to be axially rotatable by the vertical chute with both ends extending to the outside of the vertical chute 51 . Of course, the path changing plate 53 rotates according to the axial rotation of the support shaft 54 .

The worm wheel 55 is fixed to one end of the support shaft 54 and meshes with the worm 57 . The worm 57 is fixed to the drive shaft of the diverting plate driving unit 56 and rotates according to the operation of the diverting plate driving unit 56 and rotates the worm wheel 55 in the direction of the arrow r or the opposite direction. As a result, it is possible to maintain the path switching plate 53 in the state of FIG. 6 or 7 through the switching plate driving unit 56 .

When the diverter plate driving unit 56 is erected vertically as shown in FIG. 6 , the medical waste 100 injected through the hopper 51a is hung on the weight sensing door 59b and is put into the combustion chamber at once. In addition, when tilted as shown in FIG. 7 , the medical waste 100 is transferred to the sequential input unit 70 via the extension conveyor 61 . The medical waste 100 transferred to the sequential input unit 70 is sequentially introduced into the combustion chamber through the inclined chute 71 .

Whether to put the medical waste 100 in a batch or sequential manner is determined according to the size or type of the medical waste 100 or the amount to be treated. For example, since the size of the medical waste 100 is small and burnt quickly, it is not necessary to sequentially input the medical waste 100 directly through the vertical passage 51b. On the other hand, it is better to continuously inject the medical waste with a large size and a type that does not burn well through the sequential input unit 70 .

The medical waste 100 discharged to the outside of the vertical chute 51 by the path change unit 52 moves to the sequential input unit 70 through the extension conveyor 61 . The medical waste 100 passing through the extension conveyor 61 falls to the inlet portion 71b of the inclined chute 71 .

In addition, the scanner 63 is installed on the upper part of the extension conveyor 61 . The scanner 63 is located on the extension conveyor 61 and scans the electronic tag 103 of the medical waste 100 passing through the extension conveyor 61 . The information grasped by the scanner 63 is transmitted to the manager through the communication module 63a.

The sequential input unit 70 serves to send down the medical waste input from the extension conveyor 61 one by one to the combustion chamber of the incinerator 40 . The sequential input unit 70 includes an inclined chute 71 , a plurality of flap dampers 73 , a damper driver 75 , and a water jacket 76 .

The inclined chute 71 provides an inclined transport path 71a so that the medical waste 100 slides down by the action of gravity, and the upper inlet 71b is located below the end of the extended conveyor 61. Located, the lower outlet portion (71c) is connected to the combustion chamber of the incinerator (40). In addition, the outer surface of the inclined chute 71 is covered with a water jacket 76 . The water jacket 76 prevents thermal deformation of the inclined chute 1 due to the high-temperature heat inside the combustion chamber.

The flap damper 73 is installed in the transfer passage 71a of the inclined chute 71 and serves to open or block the transfer passage. When the flap damper 73 blocks the transfer passage 71a, the heat inside the combustion chamber is prevented from rising upward. The flap damper 73 is rotatably installed inside the inclined chute 71 and rotates in the arrow a direction to open the transfer passage 71a, or rotates in the opposite direction to block the transfer passage 71a.

The rotational movement of the flap damper 73 is implemented by the damper driver 75 . The damper driver 75 is installed on the outer side of the inclined chute 71 , and receives a control signal from the controller 35 to rotate the flap damper 73 . As long as the flap damper 73 can be rotated, the operation method of the damper driver 75 can be changed.

The damper driver 75 opens and closes the flap damper 73, but opens and closes the medical waste 100 to descend in stages. For example, when the medical waste 100 is placed on the uppermost flap damper 73 , the uppermost flap damper 73 is first opened while all the flap dampers 73 are closed. As the uppermost flap damper 73 is opened, the medical waste 100 falls and is caught in the second flap damper 73 . In the meantime, the uppermost flap damper 73 is immediately closed.

If the uppermost flap damper 73 is closed, the second flap damper 73 is opened to send the medical waste 100 down one step further and closes itself. The medical waste 100 is caught in the third flap damper 73 . The third flap damper is opened after the second flap damper 73 is closed. When the third flap damper 73 is opened, the hung medical waste 100 is introduced into the combustion chamber through the outlet portion 71c.

In this way, the plurality of flap dampers 73 are operated by the control unit 45 to repeat the opening and blocking of the transfer passage 71a, but alternately block the transfer passage in order to prevent gas tightness and backfire of the combustion chamber. . For example, at least one flap damper 73 among the plurality of flap dampers 73 blocks the transfer passage 71a.

The above-described series of processes is controlled by the controller 45 , and the medical waste 100 descends step by step and sequentially in the inclined chute 71 to reach the combustion chamber.

In the above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical idea of the present invention.
