[2]
Background Art
[3] There have been developed many methods and various devices to treat an infectious waste which is generally discharged from a hospital. Among methods which sterilize and treat an infectious waste, the most effective one is to use a micro wave or a pressured vapor.
[4] A micro wave has advantages that enable to heat a subject rapidly and to sterilize a waste by disrupting a cell membrane with electromagnetic wave.
[5] However, there is drawback in that a heating effect of a micro wave is depend on gene properties of a subject so that a heating efficacy is different to a kind of subjects and, in case of being mixed with various matters such as a waste, homogeneous sterilization can not be achieved.
[6] Also, in case of having low moisture content, a micro wave is not absorbed so that heating/sterilizing effect is reduced.
[7] The processing device using a pressured vapor is to maintain the inside of a pressure vessel to a state of saturated vapor pressure by providing a heated vapor from a vapor generator with the pressure vessel having a determined volume, thereby internal pressure of a pressure vessel being formed higher than atmosphere pressure and a temperature also being maintained above a boiling point of water. With being maintained to such high pressure and high temperature during a determined time, it is possible to treat a waste homogeneously regardless of a kind of wastes and moisture content
[8] However, a non-continuous processing device of autoclave type has been generally used to maintain internal pressure of a pressure vessel so that, incase of a continuous processing device which wastes enter and leave continuously, it is not easy to maintain internal pressure.
[9] To solve the said problem, an infectious waste processing apparatus has been disclosed which make it possible to sterilize through two steps with a pressured vapor and a micro wave, and is consisted with continuous type.
[10] Figure 1 is a schematic view showing a conventional infectious waste processing apparatus, and figure 2 is a sectional view showing internal features of the third processing part.
[11] Referring the said figures, a conventional infectious waste processing apparatus is consisted of the first processing part 1 which smashes infectious wastes introduced through an inflow hopper Ia with a smashing device Ib and then discharges it through a discharging hopper Ic, the second processing part 2 treats smashed infectious wastes transferred from the first processing part by sterilizing with pressured vapor of high temperature, and the third processing part 3 which re-sterilizes infectious wastes being first sterilized by the said second processing part 2 with a micro wave. In the said apparatus, rotary input-output devices 4 are installed between the said first processing part 1 and the second processing part 2, and between the said second processing part 2 and the third processing part 3 respectively so that internal pressure is easily maintained, thereby enabling to treat infectious wastes continuously.
[12] However, there is a drawback which an operator of the said processing apparatus is exposed to noxious micro wave at naked state since such conventional infectious waste processing apparatus discharge infectious wastes being treated with sterilization at an outlet 3a of the third processing part 3 and simultaneously discharge a micro wave.
[13] Therefore, a shielding means has been demanded which make it possible to prevent such leakage of a micro wave.
[14]
Disclosure of Invention Technical Problem
[15] The present invention is created to solve the above-mentioned drawback in the prior art. Therefore, object of the present invention is to provide an infectious waste processing apparatus which increases a sterilizing efficacy by sterilizing through two steps with a pressured vapor of high temperature and a micro wave with continuous type, eliminates a risk element for an operator's health according to leakage of a micro wave by extinguishing a micro wave with fixing a shielding means on an inner wall side of an outlet of the second processing part, and sterilizing effects of the second processing part and the third processing part are increased because an infectious waste smashed by a separation unit that is connected and bound to a lower portion of a smashing device of the first processing part has more increased separation efficacy by shock or friction according to being the said waste rotated with high-speed so that an exposed area to outside of it is increased.
[16]
Technical Solution
[17] To achieve the said object, the present invention has features which are as follows.
[18] The apparatus according to the present invention is characterized in that it is consisted of the first processing part which smashes infectious wastes introduced through an inflow hopper with a smashing device and then discharges it through a discharging hopper, the second processing part which treats smashed infectious wastes transferred from the first processing part by sterilizing with pressured vapor of high temperature, and the third processing part which re-sterilizes infectious wastes being firstly sterilized by the said second processing part with a micro wave, and rotary input-output devices are installed between the said first processing part and the second processing part, and between the said second processing part and the third processing part respectively so that internal pressure is easily maintained, thereby enabling to treat infectious wastes continuously, wherein the said third processing part includes a housing having a determined receiving space, an inlet which is formed at upper side of the said hosing and through which infectious wastes being sterilized firstly are introduced by a rotary inlet-outlet device, a delivery part which is positioned in the said housing and transfers the introduced infectious wastes, a micro wave generator which is fixedly bound at the central portion of the said housing and inject a micro wave into the housing, an outlet which is formed at lower side of the said hosing and to discharge infectious wastes being sterilized by a micro wave to outside, and the number of shielding means which is fixedly bound at the inner wall of the said outlet and shields a micro wave leaked into the said outlet.

Figure imgf000004_0001
which is constructed with a metal plate being triple crooked and have cutting groove of perpendicular and horizontal direction, and a rotary input-output device is formed at the said outlet with the state being connected and bound. [20] Alternatively, the said micro wave generator is preferably magnetron. [21] Also, a separation unit is connected and bound at lower side of smashing device of the said first processing part 1. The said separation unit is consisted of a fixed outer cylinder, a rotatable inner cylinder which is positioned in the said outer cylinder, and an outlet which is formed at lower side of the said outer cylinder and discharges an infectious wastes being introduced.

[22]

[23] According to the present invention, it can be achieved an effect that increases a sterilizing efficacy by sterilizing through two steps with a pressured vapor of high temperature and a micro wave with continuous type,
[24] Also, the present invention can eliminate a risk element for an operator's health according to leakage of a micro wave since it is extinguished by constructing a resonant circuit with fixing a shielding means on an inner wall side of an outlet of the second processing part.
[25] Besides, sterilizing effects of the second processing part and the third processing part are increased because an infectious waste smashed by a separation unit that is connected and bound to a lower portion of a smashing device of the first processing part has more increased separation efficacy by shock or friction according to being the said waste rotated with high-speed so that an exposed area to outside of it is increased.

Best Mode for Carrying out the Invention
[49] The infectious waste processing apparatus according to the present invention will be now made in detail together with the attached drawings.
[50] Figure 3 is a view showing the third processing part to which a shielding means is joined according to the present invention, and figure 4 is a perspective view showing a portion A of figure 3. Figure 5 is a view showing the third processing part according to another embodiment of the present invention.
[51] Figure 6 is a view showing the first processing part to which a separation unit is joined, and figure 7 is a view showing a separation unit schematically.
[52] Referring to the figures, the resent invention is grossly consisted of the first processing part 10, the second processing part 20, the third processing part 30, and a rotary inlet-outlet device 40.
[53] Wherein, the said first processing part 10 plays a role charging of a process which infectious wastes are introduced and then smashed, and such the first processing part 10 is consisted of an inflow hopper 11 in which infectious wastes are flowed, a smashing device 12 charging of crush, and a separation unit 13 which maximizes a separating efficacy with high-speed rotation, friction and shock of crushed infectious wastes.
[54] The said separation unit 13 receives infectious wastes crushed by a smashing device
12, and consisted of a fixed outer cylinder 13a, a inner cylinder 13b which is positioned in the said outer cylinder 13a and rotatable by a motor, a discharging device 13c which is formed at lower side of the said outer cylinder 13a and discharges infectious wastes, and a wing 13d which is coupled at the peripheral of the said inner cylinder 13b and rotates together with the inner cylinder 13b. [55] Such a separation unit 13 rotates together with a wing 13d rotating with high-speed so that it is easily achieved for gradually descending infectious wastes to separate by colliding each other and rubbing action during rotating process.
[56] Such a separation effect functions to further enhance a sterilizing effect of the second processing part and the third processing part which is next process. If separation is smoothly achieved, a sterilizing effect is also increased, while, if infectious wastes are adhesive each other though it is well crushed, sterilizing power by pressured vapor of high temperature and a micro wave is reduced.
[57] As a matter of course, a discharging device 13c which is formed at lower side of a separation unit 13 is connected with a rotary inlet-outlet device 40 which is bound between the second processing part 20, thereby making it possible to maintain internal pressure of the second processing part 20 easily.
[58] On the other hand, the second processing part 20 firstly sterilizes introduced wastes with pressured vapor of high temperature, and crushed wastes being treated with sterilization are transferred to the third processing part 30.
[59] The said third processing part 30 is consisted of a housing 31 having a determined receiving space, an inlet 32 which is formed at upper side of the said hosing 31 and through which infectious wastes being sterilized firstly are transferred by a rotary inlet- outlet device 40, a delivery part 33 which is positioned in the said housing 31 and transfers the introduced infectious wastes, a micro wave generator 34 which is fixedly bound at the central portion of the said housing 31 and inject a micro wave into the housing 31, an outlet 35 which is formed at lower side of the said hosing 31 and to discharge infectious wastes being sterilized by a micro wave to outside, and the number of shielding means 36 which is fixedly bound at the inner wall of the said outlet 35 and shields a micro wave leaked into the said outlet.
[60] Namely, infectious wastes which are firstly sterilized by the second processing part
20 are introduced into a housing 31 through an inlet 32 of the third processing part 30, and then directly dropped to a delivery part 33 and arrived safely.
[61] According to one embodiment, the wastes are horizontally transferred to an opposite side of an inlet 32 by a delivery part 33 which is made up of a rotary roller and a conveyer belt and simultaneously exposed to a micro wave irradiated by a micro wave generator 34 which is installed at the central portion of the said housing 31.
[62] Therefore, with being moved to an outlet 35, an opposite side of an inlet 32, simultaneous with being sterilizing by a micro wave, the secondly sterilized wastes are discharged to outside through an outlet 35.
[63] The moving speed of the said delivery part 33 is related to sterilizing effect of a micro wave so that it is surly possible to vary to a various form according to setting up. Also, even though we represent a delivery part which is made up of a rotary roller and a conveyer belt with one layer at the drawing, it is surly possible to form it with multilayer more than two to increase exposing time for a micro wave to maximum level. [64] Also, it is preferable to construct the said shielding means 36 to have its plan section of shape of '
Figure imgf000008_0001
which is constructed with a metal plate being triple crooked and have cutting groove of perpendicular and horizontal direction.
[65] Such a shielding means 36 is to prevent leakage of a micro wave through an outlet
35. Such preventing mechanism is such that a metal plate being triple crooked make wavelength of a micro wave to be overlapped, thereby offsetting wave motion and extinguishing a micro wave.
[66] Besides, leakage of a micro wave can be better prevented by binding a rotary inlet- outlet device 40 to lower side of the said outlet 35.
[67] Also, even though the said micro wave generator 34 is preferably a number of magnetron, the present invention do not limit to it but use all generators that can irradiate a micro wave.
[68] Figure 8 is a perspective view showing a rotary inlet-outlet device 40 according to the present invention.
[69] Referring to the figures, a rotary inlet-outlet device is constructed such that an adaptor 43 which is a connecting portion of the second processing part 20 and a hopper 42 which wastes removed and discharged is attached to a cylinder housing 41.
[70] A shaft 44 which a disc 45 and a blade 46 are bound is formed through into a cylinder housing 41. Rubber sealing materials are attached on circumference of a disc 45 and the end of a blade 46 to keep pressure.
[71] Next, moving process of a rotary inlet-outlet device 40 will be explained.
[72] The said shaft 44 of a rotary inlet-outlet device 40 is constructed such that it is rotated with constant speed, and wastes are filed up in an empty space being formed by a disc 45 and a blade 46.
[73] Since a disc 45 and a blade 46 are rotated together with movement of a shaft 44 which rotates with constant speed, the filed wastes can be continuously transferred with maintaining an internal pressure of the second processing part 20 and the third processing part 30.
[74] While the present invention has been described with reference to the particular embodiment illustrated at drawings, it is not to be restricted by the embodiment but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiment without departing from the scope and spirit of the present invention.
