Inside the drying cylinder 7, a screw blade (ribbon screw) 9, which is an example of a stirring and transferring means, is provided on the hollow rotary shaft 5 from the lower portion of the hopper 8 to the opening 7 a via a support 10. ing. The support 10 has a column 10a projecting radially from the rotation shaft 5, a linear support blade 10b is disposed between the front and rear ends thereof, and a screw blade 9 is wound around the support blade 10b. It consists of a configuration.

A combustion tube 11 is provided inside the tip of the casing 3.
Are fixed to the hollow rotary shaft 5 via the supports 12a and 12b so as to surround the hollow rotary shaft 5. The combustion cylinder 11
It comprises a drum screen in which a fire grate 11b having a substantially same diameter and formed in a tubular shape is connected to a base end tubular portion 11a made of a metal tubular body. The base tube 11 a is provided with the drying tube 7.
And is arranged at a rotatable interval so as to be externally fitted to the tip of the grate, and serves as a relay portion for transferring the material to be burned transferred from the drying cylinder 7 to the grate 12b.

Next, the grate 11b is formed by arranging a plurality of linear bars extending in the front-rear direction at equal intervals in the circumferential direction, and using a long round bar to spirally surround the bar to the discharge side. And a cylindrical shape such that predetermined eye holes are formed before and after. As a result, the object to be burned in the grate 11b exerts a force in the direction of rotation due to the rotation of the grate 11b. However, since the peripheral wall of the grate 11b is formed of a spirally wound round bar, it is discharged. Guided in the direction.

The transfer of the burnable material is not limited to the above structure,
A transfer blade or other transfer means for transferring the burnable material into the grate 11b may be provided. On the outer wall surface of the grate 11b, a transfer means 13 composed of a ribbon screw for transferring the ash dropped from the eye hole of the grate 11b to the front side (discharge side) is spirally mounted.

At the bottom of the casing 3, the grate 11b
The ash outlet 14 is located at the position corresponding to the tip from the middle position
An opening 15 is formed at a position corresponding to the tip of the grate 11b, for discharging unburned materials discharged from the tip of the grate 11b. In the figure, reference numeral 16 denotes a flame lid, and a smoke collecting chamber 17 is provided in the casing 3.
Is formed, and the grate 1 is provided at the top of the casing 3.
A smoke outlet 18 for discharging smoke accumulated in the smoke collecting chamber 17 is formed near the tip of 1b.

Next, at the front end of the casing 3, a mouth of a burner 19 for emitting a flame is provided below the smoke collecting chamber 17. Similarly, at the base end of the casing 3, a burner 19 ′ that emits a flame to the base end of the drying cylinder 7.
The mouth is provided. Thereby, each burner 1
The drying cylinder 7 and the combustion cylinder 11 can be heated at 9 and 19 ', respectively. Further, the heating amounts of the burners 19 and 19 'may be the same, but in this embodiment, the heating can be changed by the controller C by changing the respective heating amounts.

Next, the hollow rotary shaft 5 has a plurality of blast holes 5a formed on the peripheral wall thereof at substantially equal intervals along the longitudinal direction, and is connected to a blower device (not shown). In the case of the illustrated example, a large number of blast holes 5a are inclined and provided at substantially equal intervals in the longitudinal direction of the rotating shaft. The flammable holes 5a are displaced at 90 ° intervals along the circumferential direction. Further, the fuze holes 5a, 5a provided facing each other in the front-rear direction are arranged so that the fumarole directions are opposite to each other. This arrangement is not limited to the above-described embodiment. In other words, the fumed holes are provided at substantially equal intervals in the circumferential direction of the rotating shaft, and the fumed directions are changed in the forward / reverse direction. It is sufficient that air (oxygen) is supplied uniformly to the air.

Therefore, the front and rear fumes 5a, 5a are set so that the front and rear fumes intersect. In the drawing, reference numerals 20 and 20 'denote connectors for connecting an air supply hose of an air supply means (not shown) for supplying air to the hollow rotary shaft 5 from outside. The supply amount of the air may be constant at all times, but in the present embodiment, the air supply amount can be appropriately adjusted by the controller C. It is preferable that a smoke exhaust treatment device (cyclone or the like) be provided at the smoke exhaust port 18 via a smoke exhaust duct (not shown).

The operation of this embodiment having the above configuration will be described. First, the smoke collection chamber 17 can be heated to an appropriate temperature by operating the burners 19, 19 '. The drying cylinder 7 fixed to the casing 3 from the hopper 8
When it is thrown in, the support blade 10b of the screw blade 9 that rotates in conjunction with the rotation of the hollow rotary shaft 5 acts as a raking blade, and the burnable material in the drying cylinder 7 is agitated, and the burner 19 at the base end. As a result, the material to be burned is dried by the primary combustion and transferred to the opening 7a side of the drying cylinder 7 because the screw blade 9 is heated and rotated by the screw blade 9 to rotate.

The burned material subjected to the drying treatment is pushed out from the drying cylinder 7 and falls onto the base cylinder 11 a of the combustion cylinder 11. Since the combustion cylinder 11 rotates in conjunction with the hollow rotary shaft 5, the burned material entering the combustion cylinder 11 burns while rolling inside the combustion cylinder 11, and granulates while being granulated. The ash smaller than the hole falls on the inner bottom wall of the casing 3. The ash is conveyed to the ash outlet 14 by the conveyor 13 and discharged.

Since the grate 11b is made of a stainless steel lead material whose peripheral wall is spirally wound toward the discharge side, if the burned material in the form of small particles is still larger in diameter than the eye hole, , And is gradually transferred to the discharge side by the rotation of the grate 11b. Those that do not fall from the eye holes of the grate 11b fall from the opening at the tip of the grate 11b and are discharged from the outlet 15. As a result, the ash can be separated from the rest and discharged.

In this case, the hollow rotary shaft 5 has a blowing hole 5a.
Are provided, oxygen can be evenly and sufficiently supplied to the rolling object to be burned even in a long and thin incinerator, and the fumarolic gas ejected from the blast holes 5a Since it crosses in the front-back direction, the hot air can be stirred, so that the combustion effect is significantly improved.

A burner 19 'is also provided at the base end of the drying cylinder 7.
The hot air inside the drying cylinder 7 is
The drying effect in the furnace is enhanced, and the heating effect is improved because the hot air of both the burners 19, 19 'at the base end and the front end of the furnace intersect at the center of the furnace. Drying cylinder 7 and combustion cylinder 11
In this embodiment, the set temperature is around 650 ° C. to 7
Although the temperature is 00 ° C., the combustion temperature of both burners 19 and 19 ′ and the amount of air supplied by an air supply means such as a blower device at both ends of the rotating shaft 5 are controlled, and the opening area of the smoke outlet is adjusted as necessary. It can be changed respectively by performing smoke emission control or the like.

A low heating temperature is suitable for drying the material to be burned. When the heating temperature is high, the material is completely burnt, and when it is at an intermediate temperature, it can be carbonized. Further, when the water content of the burnable material is high, the number of revolutions of the combustion cylinder 11 (the number of revolutions of the rotary shaft 5) needs to be reduced, and the speed can be adjusted each time according to the moisture content of the burnable material. The optimum values of these temperatures are experimentally determined in accordance with the type of the burnable material and the input amount (see the figure), and are stored as data for the controller C.

For this purpose, the controller C can automatically control the driving means 6 such as the rotation motor of the rotating shaft 5, the air supply means 20 such as a blower device, and the burner 19. That is, as shown in FIG. 10 and FIG. 11, the type of the burnable material (type classified by material, moisture content, etc.) and the input amount, and the degree of combustion (“dry”, “carbonized”, “incinerated”) ) Is input to the controller C via input means such as buttons. In the controller C, the arithmetic processing unit determines the heating temperature by the burner, the air supply amount by the blower corresponding thereto, and the time for heating the transferred object (residence time in the furnace) based on the input condition. .
In this case, as shown in FIG. 12, since the relationship between the heating temperature and the residence time in the furnace has a fixed relationship for each type of burnable material, the control value is determined based on this data. Based on this determination, the heating temperature of the burner is controlled via an actuator (not shown), the burner heats the inside of the furnace at a predetermined temperature, the amount of air supplied is controlled, and air is blown from the blast holes. The rotation motor of the rotating shaft is controlled so as to correspond to the internal residence time, and the rotating shaft rotates at a predetermined speed to determine the moving speed of the burnable material in the furnace.

Further, the operation pattern may be determined by the arithmetic processing unit based on the input conditions, and the combustion in the drying cylinder and the combustion in the combustion cylinder may be separately controlled based on the operation pattern. Good. For example, in a combustion pattern for incineration of cuttings, the burner 19 'of the drying cylinder 7 is used.
, The heating temperature is set lower than the ignition temperature of the material to be burned, heating is performed for a predetermined time, and drying is performed. Then, using both the burners 19 and 19 ′, the maximum temperature considerably higher than the ignition temperature is used. By setting to and heating for a predetermined time,
Perform incineration. Further, in the carbonization pattern for incineration of cuttings, both burners 19, 19 'are heated to the maximum temperature for a predetermined time, and the air supply amount is set to a necessary theoretical air amount or more. The temperature is lowered to a temperature slightly higher than the ignition temperature, and the air supply amount is reduced by 50% of the theoretical air amount, and heating is performed for a predetermined time. Then, after the heating is completed and the inside of the furnace is at normal temperature, the furnace is discharged to obtain a carbide, and the like. In addition, if the combustion cylinder is tilted so that the tip is upward using a lifting device as described later, the residence time in the combustion cylinder can be adjusted regardless of the speed of the rotating shaft. As described above, by controlling the heating temperature and the heating time, it is possible to perform the optimal combustion according to the property and the degree of combustion of the object to be burned.

As a specific example, when treating 1.5 m ³ of cuttings such as street trees (water content: 59%), the furnace temperature is 650.
° C, the number of rotations of the combustion cylinder is 10 rpm, and the throughput is 1.25 m ³ /
H, when the processing time is 72 minutes, the discharged amount is 0.2
m ³ , volume reduction rate of 13.3%, inner diameter of 2 mm or more was 0.08 m ³ , 2 mm or less was 0.1 m ³ , and cyclone collection was 0.02 m ³ , and a good incineration effect was obtained. The result obtained by changing the specifications in this process is as follows.

Since the firing temperature of the cuttings is about 142 ° C., the furnace temperature is set to 120 ° C. using the burner 19 ′ on the drying cylinder 7 side, the rotation speed of the rotating shaft 5 is 5 rpm, and the processing time is 20 minutes. In minutes, the water content of the cuttings was reduced to 13%. Thereafter, the furnace temperature was raised to 65 using both burners 19, 19 '.
The temperature was set to 0 ° C., and the number of revolutions of the combustion cylinder 11 was set to 10 rpm for incineration. As a result, compared to the above case, the processing time is reduced by one.
One minute could be shortened.

The burners 19, 19 'are used to treat the above cuttings, the furnace temperature is set to 650.degree. C., the rotation speed of the combustion tube 11 is set to 5 rpm, and the combustion components burn. After the elapse of 20 minutes, the furnace temperature is lowered to 180 ° C., the air supply is reduced by 50% of the theoretical air amount, and the cyclone capacity is set to 50%.
After a lapse of minutes, the operation was stopped. The contents were discharged by rotating the combustion cylinder 11 at high speed with the furnace at normal temperature. In the discharge amount is about 0.85 m ^3, these diameter at 2mm or less 0.05 m ^3, the remaining non-incinerated was obtained as following granular porous carbide grain size 6 mm.

As described above, in this embodiment, the burning degree of the incinerated material is controlled by controlling the amount of the material to be burned, the temperature in the furnace, the amount of air supply, the amount of exhaust, and the number of rotations of the rotating shaft. It was recognized that it could be changed arbitrarily. In particular, by providing a burner also at the base end of the furnace and sending air from the rotating shaft, efficient combustion can be performed in the drying cylinder. In addition, the obtained carbide can be used as a resource, and the incinerated gravel-like ingot obtained by incinerating sludge can be reused for landfill.

In addition, the rotation of the combustion cylinder 11 that rotates in conjunction with the hollow rotary shaft 5 is slowed down, the object to be burned is dried in a state where the furnace temperature is low, and then the temperature is raised to a high temperature for combustion or carbonization. Alternatively, it can be operated according to the application. In this case, the front portion of the casing 3 can be raised by the operation of the elevating device 21 in order to prevent the burnable material from advancing during drying.

FIGS. 5 to 9 show a car-mounted incinerator.
Since the incinerator 1 is the same as that of the first embodiment, the same components are denoted by the same reference numerals and description thereof is omitted. The casing 3 of the incinerator 1 is mounted and fixed on a truck 23 via a gantry 22. A first pipe conveyor 24 for continuously transferring the burnable material is detachably connected to the hopper 8 at the input port so as to extend from the left outside of the vehicle.
