Description

  The present invention relates to a garbage processing machine that microbiologically processes residues such as seafood and vegetables produced in kitchen facilities, kitchens, and the like, and garbage such as leftovers.

Conventionally, as a relatively small device for treating garbage generated from kitchen facilities, kitchens, etc., for example, a plurality of stirring blades are provided on the inner surface of a rotating drum, and the garbage is disposed in the drum from an input pipe connected to the side of the drum. Is known, and a decomposition bed containing microorganisms and garbage are stirred together, and air in the drum is supplied / exhausted by a supply / exhaust system (see, for example, Patent Document 1). It has been.
JP-A-8-117728

However, in the apparatus as described above, the microbial treatment is a batch type, and after the treatment of the garbage input from the input pipe is completed, the medium and the processed material are all discharged from the drum outlet, so that it can still be used. There was a problem in that even microorganisms were discharged together, resulting in waste.
In addition, the air supplied to the drum is heated with a heater. However, if the decomposition bed is a powdered material such as sawdust, the sawdust contains moisture and the decomposition bed is sticky. As a result, there is also a problem that the processing ability of microorganisms decreases due to lumping.

Therefore, the present invention is designed so that even when the microbial treatment is finished, it is possible to effectively use all the microorganisms without discharging them as necessary, and the medium for holding the microorganisms and garbage The purpose is to make it difficult to become agglomerate and to maintain the microbial treatment capacity by crushing it even if it becomes agglomerated.
At this time, the apparatus can be reduced in size and weight as much as possible so as to be suitable particularly as an apparatus for processing garbage generated in a kitchen such as a canteen or at home.

  In order to achieve the above object, the present invention provides a rotating drum which is loaded with a medium for holding microorganisms and garbage and rotated around a horizontal rotation axis by a driving means, a heating means for heating the rotating drum, and the rotation In the garbage processing machine provided with supply / exhaust means for supplying / exhausting air to / from the drum, the rotating drum is a vertically long drum whose longitudinal width is longer than the lateral width, and an end surface on one end side in the longitudinal direction of the rotating drum Is provided with a slot for feeding a medium and garbage into the drum, and a part of the internal space is divided into two in the lateral direction inside the other end of the rotary drum in the longitudinal direction. In addition to providing a partition wall, the end surface or side surface of the rotating drum on the side is provided with two outlets that can discharge the medium and garbage in the partition space corresponding to the partitioned space. did.

By making the rotating drum a vertically long drum, for example, even when the medium and garbage are stuck at the bottom of the drum and become sticky, the drop stroke when peeling off from the top of the drum during rotation is increased. Can increase the crushing effect of the mass.
In addition, an inlet is provided on one end surface in the longitudinal direction, a partition wall is provided in the drum on the other end side, and a part of the internal space is divided into two, and a discharge port corresponding to each partition space is provided. By providing, when discharging, if only one discharge port is opened as necessary, it is possible to leave about half of the medium inside. For this reason, effective utilization of microorganisms is achieved.

  Further, in the present invention, the rotary shaft of the rotary drum can be passed through the rotary drum, and the supply pipe and the exhaust pipe of the supply / exhaust means can be inserted into most of the through parts that pass through the drum. A hollow cylinder was formed, and air was supplied from one end of the hollow cylinder into the drum through the air supply pipe, and the air in the drum was exhausted from the end on the same side of the hollow cylinder through the exhaust pipe.

In this way, if air is supplied and exhausted into the drum using the rotating shaft portion of the drum, the apparatus can be reduced in size, but in particular, the air supply and exhaust can be performed only from one side of the rotating shaft. As a result, the apparatus can be made smaller and simpler.
In addition, by passing the hollow shaft through the inside corresponding to the rotating shaft of the drum, there is an increased opportunity for the lump that has been peeled off from the upper part of the drum during rotation to collide with the hollow shaft, and the function of crushing the lump is enhanced. For this reason, if necessary, the upper surface of the hollow shaft in the drum may be formed in a concavo-convex shape, or a sharpened portion may be provided to enhance the crushing effect.

In a garbage processing machine that performs microorganism treatment while stirring the medium holding the microorganisms and garbage by rotating the rotating drum, the longitudinal direction of the rotating drum is directed in the vertical direction, and the end surface on one end side in the longitudinal direction In addition, the internal space on the other end side in the longitudinal direction is divided into two by a partition wall, and a discharge port is provided corresponding to each partition space portion, so that effective use of microorganisms can be achieved. Therefore, the crushing effect can be enhanced even if the medium or garbage becomes hard.
Further, if a hollow cylinder is provided in the rotating shaft portion, and supply / exhaust is performed from one end of the rotating shaft using this hollow tube portion, the apparatus can be further reduced in size and simplified, and the drum The hollow cylinder inside can be used to enhance the crushing effect on the falling mass.

Embodiments of the present invention will be described with reference to the accompanying drawings.
Here, FIG. 1 is a partial cross-sectional view of the microorganism treatment apparatus according to the present invention as seen from the front, FIG. 2 is a side view as seen from the direction AA in FIG. 1, and FIG. FIG. 4 is a diagram illustrating another configuration example in the case where the discharge port is provided on the side surface of the drum.

  The garbage processing machine of the present invention is suitable for an apparatus for easily treating microorganisms by, for example, introducing microorganisms and garbage into a rotating drum when processing garbage generated in a cafeteria kitchen or home. It is designed to be as small and light as possible, and when the treatment is completed, it can be effectively used by leaving a part without discharging all microorganisms as necessary. ing. The medium for holding microorganisms and the garbage are considered to be less likely to be agglomerated, and even if it becomes agglomerated, it is crushed into small pieces so that the ability to treat microorganisms can be maintained.

  That is, as shown in FIG. 1, the present garbage disposal machine 1 is made of a stainless steel that is rotatable on a rotating shaft 3 that is installed on a pair of support columns 2 and a bearing 4 on the rotating shaft 3. The rotary drum 5 is a rotary shaft 3 in which a longitudinal drum having a longitudinal length a longer than a lateral width b is used, and a middle portion in the longitudinal direction penetrates in the horizontal direction. It is supported rotatably. An overhang portion 5h for holding the bearing 4 is formed in the central portion of the rotary drum 5 through which the rotary shaft 3 is inserted, and the rotation for rotating the rotary drum 5 to the overhang portion 5h on one side is formed. A drive mechanism 6 is connected.

  The rotational drive mechanism 6 is attached to a driven gear 7 fixed to one overhanging portion 5 h, a drive source 8 such as a motor fixed to the support column 2 on one side, and a drive shaft of the drive source 8. A drive gear 9 and a chain 11 wound between the drive gear 9 and the driven gear 7 are configured so that a rotational force can be transmitted to the rotary drum 5 by the operation of the drive source 8.

Then, inside the rotating drum 5, a medium such as a ceramic holding a microorganism, a rice husk or a wood chip, and garbage can be input or discharged, and the input port T at this time is a rotating drum. 5 is formed on the end face on one end side in the longitudinal direction, and can be opened and closed by a closing door 12. In addition, a partition wall 13 for partitioning a part of the internal space in the lateral direction is provided inside the other end of the rotary drum 5 on the side opposite to the charging port, and corresponds to the two partitioned space portions. The other end side end face is provided with two outlets H, and each outlet door 14 can be opened and closed.
Further, a heater wire 24 of the heating means 20 described later is provided on the outer surface of the rotating drum 5.

The rotary shaft 3 is formed by integrating a large-diameter hollow cylinder 3 a supported by a bearing 4 on one side and a small-diameter shaft 3 b supported by a bearing 4 on the other side. Most of the penetrating portion that penetrates the tube is a hollow cylinder 3a. The air supply pipe 16 and the exhaust pipe 17 are inserted from the same direction into the cylinder from the opening of the hollow cylinder 3a, and the air supply pipe 16 and the exhaust pipe The extended end portion 17 protrudes from the hollow cylinder 3 a upward toward the outside of the cylinder, and is in communication with the rotary drum 5. Also, a cover is provided at the upper ends of the air supply pipe 16 and the exhaust pipe 17 that have jumped into the drum so that falling objects and the like from above do not enter the pipe.
The base end side of the air supply pipe 16 is connected to an air supply source (not shown), and the base end side of the exhaust pipe 16 is connected to an exhaust part (not shown) via a purifier 18.
In the present embodiment, one end side of the rotating shaft 3 is made a small diameter as the small diameter shaft 3b, but it is not always necessary to make the diameter small, and the large diameter may be kept. However, by reducing the diameter of one side of the rotating shaft 3, not only the bearing mechanism can be downsized but also the entire apparatus can be downsized.

The heating means 20 includes a support plate 21 attached to the overhanging portion 5h of the rotation drum 5 on the side opposite to the driven gear 7 mounting side, and two copper-made attachments attached to the support plate 21. Ring contacts 22 (FIG. 2) and carbon brushes 23 that can contact each ring contact 22 and allow electricity to flow, and the heater wires 24 (FIG. 1) are connected to each ring contact 22. At the same time, the heater wire 24 is wound around the outer surface of the rotary drum 5 and the periphery thereof is covered with a heat insulating material 25 such as ceramic wool.
Then, electricity is supplied to the heater wire 24 through the carbon brush 23 to heat the rotary drum 5.

The operation of the garbage processing machine 1 as described above will be described.
First, the rotating drum 5 is heated by the heating means 20 to set the temperature conditions suitable for the growth and growth of microorganisms. The medium and the garbage holding the microorganisms are input from the inlet T and rotated by the rotating mechanism 6. The drum 5 is driven to rotate. Along with this, air is sent from the air supply pipe 16 into the drum, and at the same time, the dirty air in the drum is exhausted from the exhaust pipe 17 to set an environment suitable for the growth of microorganisms.

  Then, the medium and the garbage are agitated in the rotating drum 5, and sufficient air is given to the microorganisms to decompose and treat the garbage. At this time, the medium and the garbage are easily solidified by the moisture generated from the garbage, and the processing ability of the microorganisms is lowered when the medium is solidified. However, in the case of the present invention, since the rotating drum 5 itself is heated, it does not easily become a lump, and even if it becomes a lump, the lump that tends to adhere to the rotating drum 5 peels off at a position where it comes upward. Since the drop stroke is large, it is easy to be crushed. In particular, when it is peeled off above the rotary shaft 3, the possibility of colliding with the rotary shaft 3 in the middle of dropping is further increased. For this reason, the processing capacity of microorganisms can be increased.

  When a predetermined time has elapsed, the rotary drum 5 is stopped with the discharge port H directed downward, and the processed material is discharged. This discharge is performed by opening only one of the two discharge doors 14 so as to discharge only the processed material in the space on one side partitioned by the partition wall 13 onto the tray 26, The processed material in the side partition space is left as it is. For this reason, the medium contained in the processed material in the partition space portion remains in the drum as it is and is reused in the next processing.

  When the discharge door 14 of the discharge port H on one side is closed, the next garbage and a new medium are input, and the microorganism treatment is performed in the same manner. It can be reduced to about half.

Then, when the second microbial treatment is completed in the above manner, the processed material is discharged from the outlet H on the side different from the previous time, and this is repeated.
According to the above procedure, the microorganisms can be effectively used, and it is difficult for the lumps to be hardened in the rotating drum 5 so that the microorganism treatment can be made more effective.

By the way, as shown in FIG. 4, the discharge port H for the processed material may be provided on both side surfaces of the rotary drum 5 corresponding to each partition space.
In this case, when discharging the processed material, the rotating drum 5 is slightly tilted and stopped so that the discharge port H faces downward.

In addition, this invention is not limited to the above embodiments. Those having substantially the same configuration as the matters described in the claims of the utility model registration and having the same operational effects belong to the technical scope of the utility model registration.
For example, the shape of the rotating drum 5 and the specific configuration of the rotating mechanism 6 are arbitrary, and the specific configuration of the heating means 20 of the rotating drum 5 is also an example.
Furthermore, you may make it provide the unevenness | corrugation, a sharp part, etc. for improving the crushing effect in the upper surface of the hollow cylinder 3a.

  It can be miniaturized as a device for treating garbage with microorganisms, has a high processing capacity, and can effectively utilize microorganisms, so it is particularly suitable for the treatment of garbage generated in restaurants, homes, etc. .
