Abstract

<P>PROBLEM TO BE SOLVED: To provide a garbage treatment apparatus capable of efficiently discharging a treated garbage out of a discharge port of the garbage treatment apparatus. <P>SOLUTION: This garbage treatment apparatus is enabled to rotate stirring means reversely and make the duration of stirring in the rotation direction for moving the treated garbage toward a discharge port side (right rotation) longer than the duration of stirring in the rotation direction for moving the treated garbage backward from the discharge port side (reverse rotation) on completion of decrease in volume of garbage. Accordingly, when moving the treated garbage toward the discharge port side, the treated garbage pinched by a treatment container and stirring blades is dropped by the rotation in the direction for moving the treated garbage backward from the discharge port side and also, since the duration of stirring in the rotation direction for moving the treated garbage toward the discharge port side is made longer than the duration of stirring in the rotation direction for moving the treated garbage backward from the discharge port side, the treated garbage can reliably be discharged out of the discharge port in a short time. <P>COPYRIGHT: (C)2006,JPO&NCIPI

  However, in a conventional garbage processing machine, when processing garbage containing a lot of long fibers such as long leeks and cut flowers, the fibrous garbage may be entangled during processing, resulting in a large fibrous mass. is there. When discharging such a lump from the discharge port to the processing object container, it moves while being sandwiched between the inner surface of the processing container and the stirring blade as shown in FIG. However, the lumps are unraveled and cannot be dropped from the discharge port to the processed material container (b), and rotate while being sandwiched, which makes it difficult to reliably discharge the processed material.

  This invention is for solving the said subject, and it aims at providing the garbage processing machine which can discharge | emit the processed material of garbage efficiently from the discharge port of a garbage processing machine.

  The present invention comprises a processing container for reducing garbage, a stirring means for stirring the garbage in the processing container, and a discharge port for discharging the processed food of the reduced garbage by rotation of the stirring means, After the garbage reduction is completed, the stirring means is rotated in the forward and reverse directions, and the processing object is moved in the direction away from the discharge port during the rotation time for moving the process toward the discharge port. The present invention relates to a garbage disposal machine characterized in that it is longer than the stirring time in the rotation direction.

  According to the present invention, after the reduction of the garbage is completed, the processed material sandwiched between the processing container and the stirring blade can be removed by reverse rotation when the stirring means is rotated, and the processed material is moved to the discharge port side. Since the agitating time in the rotating direction is increased to make it easier to move the processed material to the discharge port side, the garbage processing machine can reliably discharge the processed material in a short time.

  BEST MODE FOR CARRYING OUT THE INVENTION The best mode of the present invention, which is considered preferable, will be briefly described by showing the effects of the present invention.

  The garbage processing machine according to the present invention is configured to rotate the agitation means forward and backward after the reduction of the garbage, and to reduce the agitation time in the rotation direction (forward rotation) for moving the processed material to the discharge port side. This is a configuration that is longer than the stirring time in the rotation direction (reverse rotation) in which the processed material is moved in the direction away from the outlet side. Therefore, the processing object sandwiched between the processing container and the stirring blade during the forward rotation can be removed by reverse rotation, and the processing object can be easily moved to the discharge port side by increasing the normal rotation stirring time. Can be reliably discharged in a short time.

  1 to 5 show an embodiment of the present invention, which will be described below. In this embodiment, a garbage processing machine for drying and reducing the amount of garbage by heating with warm air will be described.

  FIG. 1 is an external perspective view of a garbage disposal machine, FIG. 2 is a side configuration diagram, FIG. 3 is a front configuration diagram, and FIG. 4 is a configuration diagram of a burner unit and an odorous air combustion chamber. First, as shown in FIG. 1, reference numeral 1 denotes a main body of the garbage processing machine, and 2 denotes an openable / closable door for putting the garbage into the main body 1. Reference numeral 3 denotes an operation unit for controlling the operation of the garbage processing machine, and a processing object container storage for storing a container for receiving a processed material dried in the main body 1 at the lower part of the operation unit 3 Part 4.

  Next, from FIG. 2, reference numeral 5 denotes a processing container housed in the main body 1 for drying garbage, 6 is a burner section for generating combustion heat necessary for drying the garbage, and 7 is discharged from the processing container 5. This is an odor air combustion chamber in which the odor component to be heated is decomposed by the combustion flame of the burner section 6. Reference numeral 8 denotes a deodorization catalyst that is activated by the combustion heat of the burner section 6 to oxidatively decompose odor components. An orthogonal heat exchanger 9 is disposed downstream of the deodorization catalyst 8 and communicates with an exhaust pipe 10 downstream thereof. Yes.

  Further, an odor air intake port 12 is provided at the upper part in the processing container 5, which is provided with an odor air suction fan 11 that sucks odorous air from the processing container 5 and blows it to the odor air combustion chamber 7. The inlet 12 and the odorous air combustion chamber 7 communicate with each other via an odorous air duct 13. That is, the odorous air from the processing vessel 5 is thermally decomposed in the odorous air combustion chamber 7, then completely deodorized through the deodorizing catalyst 8, passes through the orthogonal heat exchanger 9 and is odorless from the exhaust tube 10. The air is discharged outside as air.

  Further, as shown in FIG. 3, a circulation fan 15 is disposed outside the circulation air suction port 14, and the circulation air suction port 14 and the circulation duct 16 are communicated with each other via the circulation fan 15. And a box body 17 provided so as to form a gap serving as an air passage around the orthogonal heat exchanger 9. Reference numeral 18 denotes a hot air outlet duct for introducing high-temperature air into the processing container 5.

  Further, a stirring means 19 for stirring the garbage is provided at the bottom of the processing container 5, and the stirring means 19 has a plurality of stirring arms 21 attached to a rotatable rotating shaft 20. A stirring blade 22 for efficiently stirring garbage is attached to the tip at a predetermined angle. Further, an agitation driving means 23 for rotating the rotating shaft 20 of the agitating means 19 is provided outside, and further, 24 is a discharge port for discharging the garbage processed material, and 25 is a processed material from the discharge port 24. It is a processed material container which accommodates. 26 is a discharge port opening / closing means for opening and closing the discharge port 24, which opens and closes the discharge port 24 by a motor.

  As shown in FIG. 4, the burner unit 6 includes a combustion fan 27, a burner 28, and a carburetor 29 that ejects fuel vaporized gas to the burner 28. Further, downstream of the burner 28, a secondary air ejection plate 31 having a number of secondary air holes 30 for ejecting secondary air is erected on both sides of the crater 32, and the odorous air combustion chamber 7 has an odor. A double structure having an outer peripheral passage communicating with the air duct 13 is formed outside, and the inside and the outside communicate with each other via a scented air ejection hole 33 formed in a large number on the opposing wall surface.

  Next, the operation in the above configuration will be described. When the door 2 of the main body 1 is opened and the garbage is put into the processing container 5 and the operation unit 3 is operated, the combustion preparation such as preheating the vaporizer 29 is started. When preheating is completed, an oil feed pump (not shown) is started, kerosene flows into the vaporizer 29, and the vaporized gas heated and vaporized is ejected to the burner 28. On the other hand, the combustion fan 27 is also started at a low speed, and the primary air flows into the burner 28.

  Therefore, the premixed gas of vaporized gas and primary air is ejected from the crater 32, ignited by an ignition device (not shown), and combustion starts. Further, secondary air is forcibly supplied from the secondary air ejection plate 31 to the combustion flame, and complete combustion occurs. And the combustion heat of this combustion exhaust gas heats the odor air combustion chamber 7, the deodorization catalyst 8, and the orthogonal heat exchanger 9, and then is discharged outside from the exhaust tube 10.

  Also, the stirring means 19 is rotated by the stirring drive means 23 before and after the start of combustion, and the garbage is crushed and stirred to increase the surface area, thereby increasing the drying efficiency. Further, at the time of agitation / pulverization, the agitation means 19 is rotated in the forward / reverse direction by the agitation drive means 23 so that the garbage is not displaced in the processing container 5 and at the same time, the lump of the fibrous processed material is Even when it is sandwiched between the inner surface of the processing vessel 5 and the stirring blade 22, it is possible to easily remove the sandwich by reverse rotation, so that the garbage is dried more efficiently.

  Further, when the circulation fan 15 is started almost simultaneously with the start of combustion, the air in the processing container 5 flows into the circulation duct 16 from the circulation air suction port 14 and is sent to the box body 17, passing through the gap in the box body 17 and orthogonally crossing. It flows into the heat exchanger 9. The air passing through the orthogonal heat exchanger 9 exchanges heat with the combustion heat of the burner 28 to become high-temperature air, flows into the processing vessel 5 from the hot air outlet duct 18, and is crushed and agitated to increase the surface area of the garbage. Will be dried efficiently.

  On the other hand, the odorous air inside the processing container 5 is ejected from the odorous air suction port 11 through the odorous air duct 13 to the odorous air combustion chamber 7 by the odorous air suction fan 11. The odor components that are thermally decomposed by the combustion flame and remain without being thermally decomposed in the odor air combustion chamber 7 flow into the deodorization catalyst 8 downstream of the odor air combustion chamber 7 and are completely oxidized and decomposed.

  As the garbage is dried as described above and the moisture in the processing container 5 is reduced, the temperature gradually rises from the upper part of the processing container 5. Then, when a temperature sensor (not shown) provided in the processing container 5 detects a predetermined temperature, it is determined that the garbage has been dried, the combustion heating power of the burner 28 is lowered, and the burner 28 is extinguished after operating for a predetermined time. Thereafter, the circulation fan 15, the odorous air suction fan 11 and the stirring means 19 are operated for a predetermined time to cool the processing container 5 and the processed product, and the drying process of the garbage is finished.

  When the drying process is completed, the motor of the discharge port opening / closing means 26 operates to open the discharge port 24 provided in the processing container 5 so that the processed material in the processing container 5 is discharged from the discharge port 24 to the processed material container 25. The agitation driving means 23 rotates the agitation means 19.

  FIG. 5 is a chart showing the rotation control of the agitation means 19 after the drying process is completed. From the figure, the rotation direction of the agitation means 19 is the rotation direction (forward rotation) for moving the processed material to the discharge port 24 side and the discharge port. The rotation direction (reverse rotation) for moving the workpiece in the direction away from the 24 side is repeated alternately. Further, the agitation time (T1) in the rotational direction (forward rotation) for moving the processed material to the discharge port 24 side, and the agitation time (T2) in the rotational direction (reverse rotation) for moving the processed material in a direction away from the discharge port 24 side. Longer than that.

  By rotating the stirring means 19 forward and backward, for example, even if a lump of processed material with a lot of fibers is sandwiched between the inner surface of the processing vessel 5 and the stirring blades 22 during forward rotation, the stirring means 19 can be easily rotated in the reverse direction. Since it can be removed, the stirring time (T2) in the rotation direction (forward rotation) for moving the processed material to the discharge port 24 side is lengthened, so that the processed material can be easily moved to the discharge port 24 side. is there.

  That is, after the garbage is dried, the stirring means 19 is rotated forward and backward, and the stirring time in the rotational direction (forward rotation) for moving the processed product to the discharge port 24 side is set in a direction away from the discharge port 24 side. By making the stirring time longer than the stirring direction in the rotational direction (reverse rotation) to move the processing object in the forward direction, the processing object sandwiched between the inner surface of the processing container 5 and the stirring blade 22 during the forward rotation can be removed by reverse rotation, and Since the forward rotation stirring time is lengthened to facilitate the movement of the processed material toward the discharge port 24, the processed material can be reliably discharged in a short time.
