Description

[Detailed description of the invention] [Industrial application field] In the invention, not only general incinerated materials, but also incinerated materials, such as harmful medical wastes, which are harmful when directly touched, are forced into the furnace chamber by pushing means. In addition, the present invention relates to a vehicle-mounted incinerator apparatus for medical waste capable of sequentially forcing an appropriate amount of incinerated material into the furnace chamber according to the weight of the incinerated material put into the furnace room and the state of the temperature in the furnace room.

[Conventional technology]

Conventionally, as an incinerator device, the inside is a combustion furnace chamber,
There are doors provided with an opening / closing door at the entrance of the furnace chamber, the opening / closing door is automatically or manually opened, and the incinerated material is directly put on the incinerated material in the furnace chamber by hands or gloves. , A proper amount of incineration material was charged in the furnace room. In addition, an opening communicating with the furnace chamber is provided at the lower part of the furnace chamber side wall, and an openable door is provided at the opening, and after the incineration is completed, the door is opened according to the operator's experience measurement as described above. Then, the ash accumulated on the bottom wall of the furnace chamber was scraped and removed.

[Problems to be solved by the invention]

However, there is a limit in the capacity of the combustion furnace chamber. If too much incineration material is added, the combustion efficiency will decrease, the temperature in the furnace will rise slowly, and the combustion time will be long. However, it is an efficient task to put an appropriate amount of incineration material into the furnace chamber.However, knowing the amount and timing of the incineration material is the experience of a skilled worker. It was impossible for an amateur worker because it was a measurement. Regarding the incineration of hazardous materials such as medical waste, even though they wear gloves, workers refuse to touch incinerated materials and work more carefully than general incinerated materials. Therefore, the working time is reduced, and the number of workers who incinerate medical waste is decreasing. And while the number of workers working on incinerated materials such as medical wastes is decreasing, the amount of medical wastes is increasing year by year, so it is a major social problem at present.

In view of the above-mentioned problems, the present invention provides a vehicle-mounted incinerator for medical waste, which can safely and efficiently incinerate harmful incineration materials such as medical waste even by amateur workers.

The detailed description of the present invention will be described based on the attached drawings. That is, the drawing is a partial cross-sectional explanatory view of a state in which the vehicle-mounted incinerator device 1 for medical waste of the present invention is loaded on the vehicle 2.
Reference numeral 3 in the figure denotes medical waste in which used syringes, gauze, and the like are stored in appropriate containers such as boxes or bags.
Further, provided at the rear end of the vehicle 2 is a supply means 4 for placing the medical waste 3 on a support table to be described later. As the supply means 4, rollers 6 are provided continuously in a row on a substrate 5 which is inclined substantially downward toward the front as shown, and both ends of the rollers 6 are rotatably mounted on both side plates 7. What you did,
Appropriate means such as a belt conveyor can be considered.

Further, a stopper member 8 is provided at the front part of the supply means 4 so as to be retractable, and the medical waste 3 is sequentially sent forward by making the stopper member 8 protrude and retract.
Then, the sent medical waste 3 proceeds further forward and is placed on a support shown as 9 in the figure. The support base 9 is vertically elongated in one or opposite side walls of the guide member 10 so as to move up and down in a guide member 10 having a housing shape opened upward.
And one end of a shaft 12 penetrating through the guide hole 11 is fixed to the support base 9, and the other end of the shaft 12 is axially attached to one end 13 a of an arm member 13 on which two rods are axially attached. ing. The other end 13b of the arm member 13 is fixed to one end or both ends of a rotatable rotary shaft 15 erected in the width direction of the input port 14 above the input port 14. Has the input port 14
Is fixed to the opening / closing door 16 which can be fitted closely.

That is, as shown by the imaginary line in the figure, the opening / closing door 16 is
Is closed, one end 13a of the arm member 13 is located at the lowest position of the guide hole 11, and the rotating shaft 15 is rotated counterclockwise in the drawing by an appropriate driving source to
And the connecting portion 13c of the arm member 13 formed by the two rods is bent, and one end 1 of the arm member 13 is bent.
3a rises along the guide hole 11 to the top of the guide hole 11, and the support base 9 also rises. When the support table 9 is at the highest position, the opening / closing door 16 is also in the maximum open state. .

In this way, the medical waste 3 located near the outside of the input port 14 is lifted by raising the support 9 so that the
As an example of the pushing means 17 for forcibly charging into the furnace from
A push member 18 having a substantially J-shaped cross section is formed on the inner wall side of the opening / closing door 16, and when the rotating shaft 15 is rotated clockwise in the figure, the medical waste 3 is moved toward the inlet 14 at the tip of the push member 18. While pressing, the opening / closing door 16 is closed as shown by the imaginary line in the figure, and the medical waste 3 is further fed into the incinerator main body 19 from the input port 14. In the present embodiment, the pushing member 18 is integrally formed on the inner surface of the opening / closing door 16. However, if the pushing member 18 is linked to the opening / closing door 16 and the medical waste 3 can be forcibly introduced into the furnace, it is adopted as the pushing means 17. You can do it.

Although not shown, if a weight measuring device is installed on the support 9, the total weight of the medical waste 3 put into the furnace is changed, and the opening and closing door 16 is measured by the opening and closing door 16. The incinerator body depends on the opening and closing time by providing a vessel
Since the amount of external air introduced into the inside of the incinerator 19 can be measured, the combustion efficiency in the furnace can be calculated, and therefore, the state of the medical waste in the incinerator main body 19 is calculated by calculating the total weight and the combustion efficiency, It is possible to know the limit of the input amount of the next input, the input timing, and the like, so that even an amateur worker with little work experience can easily work.

The medical waste 3 forcibly injected into the incinerator body 19 as described above is first placed on a metal skewer-shaped roaster 21 installed in an incineration chamber 20 below the inlet 14 and burned by a combustion burner 22 or the like. Is done. At this time, medical waste 3 generated by combustion
The ash or the like falls downward from the skewer-shaped gap of the roaster 21 or makes one end of the roaster 21 rotatable, and is rotated substantially downward as indicated by an imaginary line in the drawing to move the ash or the like below the roster 21. Drop it. The ash and the like dropped on the bottom wall 23 of the incinerator main body 19 can be opened and closed as in the related art, and can be scraped out of the furnace body with a long cleaning tool. As shown in the figure, the bottom wall 23 of the incinerator main body 19 is inclined to one side, and a groove 24 is formed at the lowest position of the bottom wall 23 over both side walls of the incinerator main body 19, and the length in the direction of the groove 24 is formed. The screw conveyor 25 is buried to open an opening 26 in the side wall at the end in the traveling direction of the screw conveyor 25, and a door that can be opened and closed is provided in the opening 26, and the screw conveyor 25 is opened by opening the door. When activated, ash and the like that have fallen on the bottom wall 23 of the furnace can be discharged from the incinerator main body 19 through the opening 26.

On the other hand, fine medical waste 3 that has not been completely burned in the incineration chamber 20, exhaust gas generated by completely burning the medical waste 3, or prone gas generated when the medical waste 3 is not completely burned, etc. Since the gas rises from the incineration chamber 20, a reburning chamber 29 is provided so that the gas and fine ash are burned again by the burner 27 or the like. Further, in the reburning chamber 29, a plurality of air blowing holes 28 are provided on a side wall, and air is sent by driving a fan or the like from outside the incinerator main body 19, so that the remaining gas is effectively reburned, so that beforehand. No gas is released to the outside. After reburning, the exhaust gas and the like flows along the exhaust gas flow as shown by the arrow in the figure and enters the settling chamber 30 communicating with the reburning chamber 29. By setting the inlet 31 which is a communication passage of the upper side and setting the cross-sectional area of the inlet 31 smaller than that of the two chambers 29 and 30, the passage resistance of exhaust gas containing natural gas is increased, and therefore, Since the airflow from the reburning chamber 29 to the sedimentation chamber 30 is suppressed at the rim of the inlet 31 of the inlet, the incineration chamber
The temperature inside the incinerator body 19 of the reburning chamber 20 and the reburning chamber 29 is likely to rise. The exhaust gas that has entered the settling chamber 30 from the inlet 31 is provided above the settling chamber 30 with the same air blowing hole as described above.
In addition to cooling the temperature of the exhaust gas from the reburn chamber 29 by providing the
The flow rate of the exhaust gas from 31 decreases and slowly flows downward as indicated by the arrow in the figure. At this time, fine dust proof and the like contained in the exhaust gas in the reburning chamber 29 naturally falls on the bottom wall of the settling chamber 30 due to its own weight. Then, in the settling chamber 30, a similar draw port 32 is formed in the lower part of the facing side of the draw port 31 to enhance the settling effect again, and the bottom wall of the settling chamber 30 is once raised by the attraction of a fan shown as 33 in the figure. Exhaust gas is guided and promoted, and only the exhaust gas that has been completely burned is discharged to the outside of the incinerator main body 19 in the direction of the exhaust stack 34 by the attraction of the fan 33. Also, a port 31 provided in the reburn chamber 29
Measurement devices such as thermocouples at the right edge of
Since the numerical value of the measuring device 35 can be confirmed by the numerical value similarly to the measuring device, if these measuring devices are in a state of a preset temperature and amount, etc., the temperature adjustment by the combustion burner 22 and the burner 27 is performed. It is also possible to automatically control the medical waste 3 by connecting the opening and closing door 16 and the supply means 4 or the stopper member 8 so as to operate the charging timing. Furthermore, when the in-vehicle incinerator device 1 for medical waste is mounted and mounted on the bed portion of the vehicle 2 as in the present invention,
If the exhaust pipe 34 of the incinerator main body 19 is provided with an extensible exhaust pipe 37 locked by pins 36 or the like, the exhaust gas can be discharged at a higher level.

[Effect of the invention]

In the incinerator device of the present invention configured as described above, the support base is higher when the opening and closing door is opened, and interlocks with the opening and closing door so as to be lower when the door is closed. Since medical waste is always placed on the support base near the inlet of the incinerator body,
It can be quickly put into the combustion chamber.

Since there is no waste in the work and the opening time of the door is constant, the amount of oxygen supplied to the incinerator main body can be calculated, and the combustion temperature in the incinerator main body is kept constant. Combustion can be realized.

In addition, by providing a weight measuring device on the support base, instead of simply measuring the weight and measuring the input amount, by using a measuring device that measures the opening and closing time and number of times on the door,
Since the external air introduction amount can be measured, the combustion efficiency in the incinerator main body can be calculated. Therefore, the state of the medical waste in the incinerator main body is calculated by calculating the gross weight and the combustion efficiency as follows. It is possible to know the limit of medical waste to be input and the timing of input. Therefore, in the past, knowing the input amount and timing of medical waste was based on the experience measurement of skilled workers, but even amateur workers can safely and efficiently incinerate medical waste. You can.

Next, the invention of this application must be automatic injection, but it is characterized by the use of an opening and closing door as a means for this automatic injection. This opening and closing door not only functions as a door but also pushes medical waste into the incineration chamber. It has both the function of taking in air and the function of taking in outside air (oxygen) at the same time.

In addition, the ash generated by the incineration of medical waste is discharged out of the incinerator main body by the screw conveyor on the bottom wall of the incinerator main body. is there.

Further, the present apparatus can be installed indoors and outdoors, but since it can be incinerated while traveling around hospitals and the like where medical waste is generated by loading it on a vehicle, the work efficiency is very good. Since medical waste can be incinerated without long-term storage, pollution due to medical waste and the like is reduced.

Thus, with the incinerator device of the present invention, even an amateur worker can perform an easy and safe operation, and can quickly incinerate medical waste and solve the problem of treating medical waste. is there.
