  However, depending on the size and material of the object to be treated, it may be difficult to achieve complete and uniform combustion in the incinerator. If the object to be treated is not completely combusted, the incineration ash of the object to be treated will be disposed of. Will also interfere. In particular, when the object to be treated is a large object made of a material that does not easily burn, it is necessary to release the flame from the burner for a long time in the incinerator and burn it in order to uniformly burn the object to be treated. Therefore, there is a problem that the processing efficiency is lowered.

  In view of the above problems, an object of the present invention is to provide an incineration processing apparatus that efficiently burns an object to be processed in an incinerator.

  In order to solve the above-described problems, an incineration apparatus according to the present invention includes a cylindrical incinerator having openings at the center portions of both end surfaces, and the incinerator with the cylindrical central axis of the incinerator horizontally oriented.

In this incineration processing apparatus, the cover member has a plurality of air holes opened toward the inner side of the incinerator for sending air from the air blowing means, and the incinerator is inward from the inner wall surface thereof. And has a protruding portion erected toward.

  In the incineration processing apparatus having the above-described configuration, the outer periphery of the incinerator is covered with a frame member, and the air blowing means is installed on the frame member, and the incinerator and the cover member It is preferable that unburned gas leaked into the frame member is fed into the incinerator together with external air from the gap and the gap between the incinerator and the exhaust part.

  Further, in the incineration processing apparatus having the above-mentioned configuration, the protrusions are rake-like crushing comprising a plurality of rod-like protrusions arranged side by side in the axial direction and standing from the inner wall surface of the incinerator toward the cylindrical central axis. It is preferable to have a protrusion and a plate-like stirring protrusion that extends radially inward from the inner wall surface of the incinerator.

  In the incineration processing apparatus having the above-described configuration, the exhaust section is installed in the combustion cylinder section, the cylindrical combustion cylinder section extending upwardly in communication with the opening on the other end face of the incinerator on the lower end side. A secondary combustion section having a heating means for releasing a flame toward the inside of the combustion cylinder section, and a combustion auxiliary means for sending air into the combustion cylinder section above the heating means; preferable.

  Further, in the incineration processing apparatus having the above-described configuration, the combustion cylinder portion finely crushes dust contained in the exhaust gas by exhaust pressure in the vicinity of the communication portion with the opening of the other side end surface of the incinerator. It is preferable to have a crushing net. Furthermore, in the incineration processing apparatus having the above-described configuration, it is preferable that the combustion cylinder portion has an inspection port that is opened at a side wall portion thereof.

Preferably it is.

  According to the incineration processing apparatus related to the present invention, air for burning the object to be treated is uniformly distributed throughout the incinerator by sending air from the plurality of air holes toward the inside of the incinerator. Therefore, it becomes easy to completely burn the entire object to be treated, thereby improving the work efficiency of the incineration process. Furthermore, the incinerator has a protrusion standing inward from the inner wall surface thereof, so that it is possible to agitate the processing object accumulated at the bottom inside the incinerator, and the air and combustion by the blowing means The flame by the means can be spread over the entire object to be treated, and the entire object to be treated can be easily burned, thereby improving the work efficiency of the incineration process.

  In addition, the blower means is configured to send the unburned gas leaked into the frame member into the incinerator together with the air generated by the shipping wind means, so that the unburned gas generated in the incinerator remains as it is. In this state, it is not released into the atmosphere, and is sent again into the incinerator by the blowing means to be completely burned, so that the influence on the surrounding environment can be kept small.

  In addition, it has rod-shaped crushing protrusions that are arranged side by side in the axial direction inside the incinerator and are erected from the inner wall of the incinerator toward the central axis of the incinerator. Since the protrusion rotates and the processing object inside the incinerator can be finely pulverized, the air by the blowing means and the flame by the combustion means can be spread over the entire processing object, It becomes easy to burn completely, so that the work efficiency of the incineration process is improved.

  In addition, a crushing net that finely crushes dust contained in exhaust gas by exhaust pressure closes the inside of the combustion cylinder part in the vicinity of the part where the combustion cylinder part communicates with the opening on the other end face of the incinerator Has been. Therefore, the dust contained in the exhaust gas having a constant wind pressure and traveling to the combustion cylinder part hits the surface of the crushing net with a constant air pressure and can be crushed more finely than the mesh of the crushing net. It becomes easy to burn completely in the part. Furthermore, since the combustion tube portion has an inspection port opened at its side wall portion, for example, the combustion state of the secondary combustion portion can be visually confirmed from the outside, and therefore incineration is possible. The operating state of the processing apparatus can be confirmed by a simple method.

  Furthermore, the incineration processing device is configured to have a dust collection unit that separates and collects dust contained in the exhaust after being burned in the secondary combustion unit, thereby removing dust contained in the exhaust. As a result, the exhaust can be made more harmless. In addition, in the exhaust cylinder that discharges exhaust into the atmosphere, exhaust is easily discharged from the exhaust cylinder by performing ventilation with the exhaust auxiliary means from the outside side of the exhaust cylinder toward the upper inside of the exhaust cylinder. The work efficiency of incineration is improved.

In the lower outer peripheral portion of the upper and lower combustion cylinder 61b, the tip of the second burner 70 is installed toward the inner side of the upper and lower combustion cylinder 61b. The second blower 75 is installed outside the combustion cylinder 61 and can generate an air flow by operating the second blower 75. The air injection pipe 76 is cylindrical and extends vertically and is fixed above the second burner 70 and inside the upper and lower combustion cylinder 61b. The other end of the blower pipe 75a having one end communicating with the second blower 75 is connected to the air injection pipe 76. The air injection pipe 76 communicates with the upper end portion. Further, the outer peripheral wall of the air injection pipe 76 has a large number of air injection holes (not shown) arranged in an array, and the air flow generated by the second blower 75 is injected from the air injection holes. It is configured as follows.

  As shown in FIGS. 1 and 8, the dust collecting unit 80 is mainly configured by a side ventilation passage 81, an upper cylinder 82, a lower cylinder 83, a dust box 84, an exhaust cylinder 90, a third blower 95, and an air layer 95b.

The air layer 95b is formed in a columnar shape above the upper cylinder 82, has a hollow portion therein, and has an exhaust pipe 90 penetrating vertically in the center. In addition, a plurality of air inlets 96 are formed in the air layer 95b so as to communicate with the hollow portion of the air layer 95b and the hollow portion inside the exhaust tube 90. Note that a cover 92 is provided above the exhaust opening 91 so that rain or the like does not enter the exhaust cylinder 90.

  Up to this point, the respective components of the incineration processing apparatus 1 have been described. Hereinafter, the operations of the respective components when the processing object is incinerated will be described.

  First, the incinerator lid 20 is opened, and the object to be treated is put into the incinerator 11. Then, by driving the motor 50, the second sprocket 51 rotates and a rotational driving force is transmitted to the first sprocket 16 via the drive chain 52, so that the incinerator 11 extends in the left-right direction. Is rotated in the direction of the rotation direction B shown in FIGS. 3 and 4. At this time, the rollers 55L and 55L and the rail 18L, the rollers 55R and 55R and the rail 18R are in contact with each other in the vertical direction, and the rollers 55L, 55L, 55R and 55R are rotated in the clockwise direction opposite to the rotation direction B. The rotation holding part 40 supports the incinerator 11 rotatably. Further, the thrust support plate 17 that rotates together with the incinerator 11 is sandwiched between the two thrust rollers 56 and 56, whereby the incinerator 11 can be restricted from moving in the left-right direction.

  Next, the 1st burner 30 and the 1st blower 35 are operated, and the processing target object in the incinerator 11 is combusted. At this time, the first burner 30 releases a flame from the tip portion toward the center of the incinerator 11. On the other hand, the first blower 35 causes the mixed air 35f to flow into the air flow path 22a and sends the mixed air 35f toward the inside of the incinerator 11 from the plurality of air ejection holes 22b.

  At this time, inside the incinerator 11, the processing object deposited on the bottom of the incinerator 11 is formed into a protruding cylinder by the crushing protrusions 14 that sequentially pass through the bottom of the incinerator 11 as the incinerator 11 rotates. It is crushed finely by passing between 14a and the projection cylinder 14a. Therefore, the air sent from the air ejection hole 22b and the flame released from the first burner 30 can be spread over the entire processing object, and the processing object can be incinerated in a short time. It is possible to increase the work efficiency.

  As described above, the crushing protrusion 14 crushes the object to be processed finely, and at the same time, as shown in FIG. 3, the stirring protrusion 15 is composed of a central protrusion 15 a and two left and right protrusions 15 b, and rotates the incinerator 11. Since it has the stirring area | region 15c opened and extended in the direction of the direction B, the to-be-processed object deposited on the bottom part in the incinerator 11 is hold | maintained in the stirring area 15c, and the incinerator 11 is the direction of the rotation direction B. By rotating, it is possible to scrape the processing object held in the stirring region 15c up to the inside of the incinerator 11 and drop it downward. By doing so, the stirring efficiency of the object to be processed is increased, and the air sent from the air ejection holes 22b and the flame discharged from the first burner 30 can be spread over the entire object to be processed, and in a short time. Since the object to be treated can be incinerated, the work efficiency of the incineration processing apparatus 1 can be increased.

  Further, in the incinerator 11, since the mixed air 35f and the flame are released from the right direction (the direction of the incinerator lid 20) to the left direction, the processing object is burned. The generated exhaust gas 11 a is discharged from the left opening 12 and flows into the left and right combustion cylinders 61 a of the secondary combustion unit 60. Here, the relatively large dust contained in the exhaust 11a is crushed by hitting the surface of the crushing net 62 with a constant wind pressure, and becomes finer than the mesh of the crushing net 62, and flows into the left and right combustion cylinders 61a together with the exhaust 11a. .

  Here, the exhaust gas 11a travels from the left and right combustion cylinders 61a of the secondary combustion unit 60 to the upper and lower combustion cylinders 61b. In the upper and lower combustion cylinders 61b, the second burner 70 emits a flame toward the center of the upper and lower combustion cylinders 61. By ejecting, the exhaust 11a is burned and rises with the flame. Air generated by the second blower 75 is injected on the surface of the air injector 76, and the exhaust air 11a in the upper and lower combustion cylinders 61 is further increased by the injected air.

  Next, the exhaust 11a that combusts in the secondary combustion unit 60 and rises to the upper end of the upper and lower combustion cylinders 61 moves upward in the traveling direction while maintaining a relatively high flow rate rising inside the upper and lower combustion cylinders 61b. From the side ventilation passage 81 to the dust collecting unit 80. At this time, in a plan view, the gas flows in the tangential direction of the inner wall surface of the upper cylinder 82 and proceeds from the upper side to the lower side while rotating at a high speed so as to draw a spiral trajectory along the inner wall surface of the upper cylinder 82. On the other hand, dust that has flown from the side ventilation passage 81 without being collected by the crushing net 62 also flows in the tangential direction of the inner wall surface of the upper cylinder 82 while maintaining a relatively high flow rate together with the exhaust 11a. Then, the centrifugal force acts on the dust so that the dust is pressed against the inner wall surface of the upper cylinder 82 while moving along the upper cylinder 82 from the upper side while drawing the spiral trajectory together with the exhaust 11a. Reach the top edge.

  Next, the exhaust 11 a and dust travel from the top to the bottom while drawing a spiral trajectory on the inner wall surface of the lower cylinder 83. At this time, since the inner wall surface of the lower cylinder 83 is formed in a triangular pyramid shape with the apex directed downward, the radius decreases with going downward, so that as the dust progresses downward from above, It is pressed against the inner wall surface of the lower cylinder 83 with a large centrifugal force. With this configuration, dust can be reliably separated from the exhaust 11a. Thereafter, the dust that reaches the lower end opening of the lower cylinder 83 falls into the dust box 84 and is collected.

On the other hand, as described above, the exhaust 11a rotates along the inner wall surfaces of the upper cylinder 82 and the lower cylinder 83 so as to draw a spiral trajectory, so that negative pressure is generated at the center of the upper cylinder 82 and the lower cylinder 83. . Therefore, the exhaust gas 11a that has traveled to the lower end of the lower cylinder 83 travels through the inner center of the upper cylinder 82 and the lower cylinder 83 that have become negative pressure, and is directed upward from the lower end of the lower cylinder 83 to the upper cylinder 82. The air flows into the exhaust tube 90, proceeds from the lower end portion of the exhaust tube 90 to the upper end portion, and is discharged into the atmosphere from the exhaust opening 91 at the upper end portion of the exhaust tube 90. At this time, by operating the third blower 95, the air flow generated in the third blower 95 is
The air is led to the hollow portion inside the air tub 95b by the blower tube 95a, and further flows into the air inlet 96 from the hollow portion inside the air tub 95b. At this time, the air flow is sent from the outer side surface direction of the exhaust tube 90 toward the inner center direction of the exhaust tube 90 and is then discharged from the exhaust opening 91 together with the exhaust 11a. The incineration ash remaining in the incinerator 11 after the incineration process is taken out by opening the incinerator lid 20.

  The effects of the present invention can be summarized as follows. First, as the incinerator 11 rotates, the projection cylinder 14a of the crushing protrusion 14 crushes the object to be processed finely, and the stirring protrusion 15 accumulates on the bottom of the inner wall surface 11b. Since the target object is scraped up and stirred above the inner wall surface 11b to easily burn the process target object, the entire process target object can be completely burned in a short time. Secondly, the incinerator lid 20 is configured to send air into the incinerator 11 from a plurality of air ejection holes 22b arranged in a circle, thereby burning the object to be treated in the entire incinerator 11. Since the air for making it spread can be spread and it becomes easy to burn a processing target object, it becomes possible to burn the whole processing target object completely in a short time.

  Thirdly, since the thrust support plate 17 is sandwiched between the two thrust rollers 56, it is possible to restrict the incinerator 11 from moving in the left-right direction during rotation. The incinerator 11 can be stably rotated continuously on the gantry 41 without deviating from the above, and the work efficiency of the incineration processing apparatus 1 can be increased. Fourth, the air flow generated by the third blower 95 is passed through the air inlet 96 and sent from the outer side surface direction toward the inner center direction of the exhaust tube 90, so that the upper end from the lower end portion of the exhaust tube 90 is increased. Exhaust gas 11a that travels to the section can be easily discharged from the exhaust opening 91, and the incineration efficiency of the incineration processing apparatus 1 can be improved.

  Fifth, the unburned gas generated in the incinerator 11 is not released into the atmosphere, but is mixed with the air generated in the first blower 35 and sent again into the incinerator 11 for combustion. As a result, unburned gas is not released into the atmosphere, and the influence on the surrounding environment can be kept small.
