Infectious Waste Processing Apparatus

The present invention relates to an infectious waste treatment apparatus for crushing and disinfecting an infectious waste, and more particularly, to sterilize secondaryly through a high pressure steam and microwave in a continuous manner to increase sterilization efficiency and to increase sterilization efficiency. By eliminating the microwaves by fixing the shielding prevention means to the inner wall of the outlet, the worker's health threat can be eliminated due to the leakage of the microwaves, and the infectivity crushed by the separating device connected to the lower part of the shredding device of the first processing unit. The present invention relates to an infectious waste treatment apparatus in which separation efficiency is increased by impact or friction as the waste rotates at a high speed, thereby increasing the sterilization effect of the second and third treatment units by increasing the external exposure area.

In general, many methods and various devices have been developed for treating infectious waste discharged from hospitals. The most efficient way to sterilize waste is through microwave or pressure steam.

Microwaves can heat objects quickly and have the advantage of sterilizing waste by breaking cell membranes by electromagnetic waves.

However, since the heating effect of the microwave depends on the dielectric properties of the object, the heating efficiency varies according to the type of the object, and there is a problem in that it is not uniformly sterilized when various substances such as waste are mixed.

In addition, when the moisture content is low, microwaves are not absorbed, thereby lowering the heating / sterilization effect.

The treatment apparatus using pressure steam is to supply the heated steam generated from the steam generator to a pressure vessel having a constant volume to maintain the inside of the pressure vessel in a saturated steam pressure state. As a result, the pressure inside the pressure vessel is formed higher than atmospheric pressure, and the temperature is also maintained above the boiling point of water. By maintaining such high pressure and high temperature for a certain time, it is possible to treat uniformly regardless of waste type and water content.

However, in order to maintain the internal pressure of the pressure vessel, autoclave-type discontinuous treatment apparatuses have been generally used. In the case of continuous treatment equipment in which waste is continuously introduced, it is not easy to maintain the internal pressure.

In order to solve such a problem, an infectious waste treatment apparatus has been disclosed that is secondary sterilizable and continuously configured through microwave and pressure steam.

1 is a view schematically showing a conventional infectious waste treatment apparatus, Figure 2 is a cross-sectional view showing the inside of the third processing unit.

Referring to the drawings, the conventional infectious waste treatment apparatus is a first processing unit 1 for crushing the infectious waste flowing into the inlet hopper (1a) through the crushing device (1b) and discharged to the discharge hopper (1c), and crushed infectious The second processing unit 2 for sterilizing the infectious waste by the high-temperature pressure steam transported with the waste, and the third processing unit for sterilizing the infectious waste firstly sterilized by the second processing unit 2 again through microwaves. It consists of (3).

In this case, the rotary I / O device 4 is provided between the first processing unit 1 and the second processing unit 2 and between the second processing unit 2 and the third processing unit 3, respectively, so that the internal pressure can be easily maintained. Waste can be processed continuously.

However, in the conventional waste treatment apparatus, the infectious waste sterilized at the outlet 3a of the third treatment unit 3 is discharged at the same time, and the microwave is also discharged so that the worker managing the treatment apparatus is exposed to harmful microwaves.

Therefore, a shielding prevention means capable of preventing the leakage of such microwaves is required.

The present invention has been made to solve the above problems to continuously sterilize the second through the high temperature pressure steam and microwave continuously to increase the sterilization efficiency, fixedly coupling the shielding prevention means to the inner wall surface of the outlet of the second processing unit By extinguishing the microwaves, the worker's health threat can be eliminated by the leakage of microwaves, and as the infectious wastes crushed by the separating device connected to the lower part of the shredding unit of the first processing part rotate at high speed, impact or friction It is an object of the present invention to provide an infectious waste treatment apparatus in which the separation efficiency is increased to increase the sterilization effect of the second and third treatment units by increasing the external exposure area.

The present invention has the following features to achieve the above object.

The present invention is a first processing unit for crushing the infectious waste flowing into the inlet hopper through a crushing device and discharged to the discharge hopper, and a second processing unit for sterilizing the infectious waste by the high temperature pressure steam transported to the crushed infectious waste and And a third processing unit for sterilizing the infectious waste firstly sterilized by the second processing unit through microwaves, and a rotational input / output device is provided between the first processing unit and the second processing unit and between the second processing unit and the third processing unit, respectively. The waste treatment apparatus capable of continuously treating infectious waste as the internal pressure is easily maintained, wherein the third treatment unit is formed on one side of the housing and a housing having a predetermined accommodation space, and is primarily formed by a rotary I / O device. Inlet for sterilizing infectious waste and infectious waste located in the housing A transport unit for transporting water, a microwave generator fixedly coupled to the center of the housing, and a microwave generator for injecting microwaves into the housing, and infectious waste which is formed on one side of the lower portion of the housing and is transported and discharged by microwaves and then discharged to the outside A plurality of outlets are formed to make and to the inner wall surface of the outlet is fixed and comprises a shielding prevention means for shielding the microwave leaked to the outlet.

It consists of a three-fold bent metal plate in the form of having a cutting groove in the transverse direction and the longitudinal direction, the outlet is formed with a rotational input and output device connected in communication.

In addition, the microwave generator is preferably a magnetron.

In addition, a separation device is communicatively coupled to the lower part of the shredding device of the first processing unit, and the separation device includes a fixed outer cylinder, a rotatable inner cylinder located in the outer cylinder, and a discharge device for discharging the infectious waste formed in the lower cylinder.

In addition, as the shielding prevention means is fixedly coupled to the inner wall surface of the outlet of the second processing unit to form a resonant circuit, the microwaves are extinguished, so that the worker's health threat due to the leakage of the microwaves can be eliminated.

In addition, as the high-speed rotation is performed by the separator connected to the lower part of the shredding device of the first processing part, the infectious waste shredded by impact or friction is more separated and the second and third treatment parts are increased by increasing the external exposure area. Sterilization effect is increased.

Hereinafter, the infectious waste treatment apparatus according to the present invention will be described in detail with the accompanying drawings.

In addition, Figure 6 is a view showing a first processing unit coupled to the separator, Figure 7 is a view schematically showing a separator.

Referring to the drawings, the present invention is largely composed of the first processing unit 10, the second processing unit 20, the third processing unit 30 and the rotation input and output device 40.

Here, the first processing unit 10 is responsible for a process in which infectious waste is introduced and pulverized. The first processing unit 10 is an inflow hopper 11 into which infectious waste is introduced, and a crushing device 12 that is responsible for crushing. And a separator 13 for maximizing the separation efficiency of the crushed infectious waste by high speed rotation, friction, and impact.

The separating device 13 has an outer cylinder 13a fixed with an infectious waste crushed by the crushing device 12 and an inner cylinder 13b located in the outer cylinder 13a and rotatable by a motor, and an outer cylinder ( 13a) is formed of a discharge device (13c) formed in the lower portion and discharged to infect the waste injected into the inner cylinder (13b) and the wing (13d) to rotate together as the inner cylinder (13b) is rotated.

The separation device 13 is rotated together by the blade 13d that rotates at high speed, but collides or frictions with each other in the course of rotating the shredding infectious waste, which is gradually descending, thereby making it easier to separate.

This separation effect increases the sterilization effect of the second process and the third process, which is a subsequent process, which is crushed, but in the case of infectious waste that is closely adhered to each other, it reduces the sterilizing power of the high temperature pressure steam and the microwave. If the separation is made smoothly, the sterilization effect is also increased.

Of course, the discharge device (13c) formed in the lower portion of the separation device 13 is connected to the rotary input and output device 40 which is in communication with the second processing unit 20, accordingly the internal pressure of the second processing unit 20 It can be more easily maintained.

On the other hand, the second processing unit 20 first sterilizes the crushed waste introduced into a high-temperature pressure steam, and thus the sterilized crushed waste is moved to the third processing unit 30.

The third processing unit 30 is formed in the housing 31 having a predetermined receiving space, and the upper side of the housing 31, the primary sterilized infectious waste delivered by the rotary input and output device 40 is introduced An inlet 32, a transfer unit 33 for transporting infectious wastes that are located in the housing 31, and a microwave generator fixedly coupled to the central portion of the housing 31, for scanning microwaves into the housing 31 34 and a plurality of outlets 35 formed on one side of the lower portion of the housing 31 and formed to discharge the infectious wastes that are introduced and transported to the outside after being sterilized by microwaves. The dog is fixedly coupled and consists of shielding prevention means 36 for shielding the microwaves leaking into the outlet.

That is, the infectious waste firstly sterilized by the second processing unit 20 flows into the housing 31 through the inlet 32 of the third processing unit 30, which immediately falls to the transfer unit 33 and is seated. .

Accordingly, the waste is horizontally transferred to the opposite side of the inlet port 32 by the conveying part 33 formed of a rotating roller and a conveyor belt according to one embodiment, wherein the waste is irradiated by the microwave generator 34 installed at the center of the housing 31. Exposure to microwaves.

Therefore, while being sterilized by the microwave and moved to the outlet 35 opposite to the inlet 32, the secondary sterilized waste is discharged to the outside through the outlet 35.

Since the moving speed of the transfer part 33 is related to the sterilization effect of the microwave, it can be changed in various forms according to the setting. In the drawing, the transfer part consisting of a rotating roller and a conveyor belt is composed of one layer, but Of course, it can be formed in multiple stages of two or more layers in order to maximize the exposure time.

' 형태로 3단 절곡된 금속플레이트로 이루어지되 횡방향 및 종방향의 절단홈을 가지도록 구성함이 바람직하다.Meanwhile, the shielding prevention means 36 has a flat cross section '

'It consists of a metal plate bent in three stages in the form is preferably configured to have a cutting groove in the transverse direction and the longitudinal direction.

The shielding prevention means 36 is to prevent the microwaves from leaking through the discharge hole 35. This preventing mechanism is to cancel the microwaves by canceling the wave by allowing the three-stage bent metal plate to overlap the wavelength of the microwaves.

In addition, by communicating with the rotary input and output device 40 in the lower portion of the outlet 35 can further prevent the microwave leakage.

In addition, although the microwave generator 34 is preferably a plurality of magnetrons, any generator capable of irradiating microwaves may be applied to the present invention, but the present invention is not limited thereto.
