Description

  The present invention relates to a litter processing machine capable of fermenting and composting litter such as leftover food from various offices and homes.

  Conventionally, various processing machines having various shapes and structures have been proposed for the processing apparatus for fermenting and processing compost from compost. However, the raw materials described in Patent Document 1 are related to the present application. There is a dust disposal apparatus or a stirring and grinding apparatus described in Patent Document 2. These devices include a processing tank capable of containing raw garbage, a stirring cylinder with a crushing hole standing in the processing tank, a stirring screw rotatably supported in the stirring cylinder, and a stirring screw And a drive mechanism for rotating the motor. Then, by rotating the stirring screw, the garbage introduced into the processing tank is introduced into the stirring cylinder, and the stirring cylinder is raised, and is pushed out from the crushing hole or the upper end opening of the stirring cylinder to be processed. The garbage is continuously crushed, stirred, and fermented while being repeatedly dropped into the inside.

JP-A-6-183870 Japanese Patent Laid-Open No. 7-8830

  In the case of the garbage processing apparatus described in Patent Document 1 and the stirring and pulverizing apparatus described in Patent Document 2, not only is it difficult for the litter introduced into the treatment tank to enter the agitating cylinder, but also litter cutting through the crushing holes. Since the action is also weak, it takes a long time to grind the litter. Further, the egg lather that has risen in the stirring cylinder due to the rotation of the stirring screw is often caught by the upper end opening of the stirring cylinder and accumulated, and is often solidified by the rising pressure by the stirring screw. For this reason, pulverization and circulation of the egg in the treatment tank are not performed smoothly, and the pulverized state is often non-uniform.

  In this way, if the mash that has been put into the treatment tank is not sufficiently pulverized and circulated, the fermentation process will not proceed well and composting will be incomplete. Moreover, if a processing process requires a long time, work efficiency will also deteriorate and the energy consumption for a driving | operation will also increase.

  The problem to be solved by the present invention is to provide a litter processing machine capable of efficiently performing composting by fermentation while pulverizing and stirring the lipped litter in a relatively short time. is there.

The egg processing machine of the present invention includes a processing tank capable of accommodating the egg, a cylindrical body that is erected in a state where a lower end is opened in the processing tank, and a plurality of through holes are formed in the peripheral wall. A stirring screw that is rotatably supported in the cylindrical body and has a helical stirring member,
A stopper is provided at the upper end of the stirring member of the stirring screw to prevent the rise of the litter.
A skirt-shaped guide member partially opened at the lower end of the cylindrical body is provided,
An auxiliary stirring member having a diameter that spirally expands along the inner surface of the peripheral wall of the guide member is connected to the lower end of the stirring member of the stirring screw.

  With this configuration, the egg thrown into the treatment tank is opened by the spiral auxiliary stirring member rotating in the skirt-shaped guide member together with the stirring screw rotating in the cylindrical body. Is introduced into the cylindrical body from the lower end of the cylindrical body, and the cylindrical body is raised by the rotation of the stirring screw. The litter rising in the cylindrical body is pushed out from a plurality of through holes provided in the cylindrical body. At that time, the lump-shaped litter is mixed with the inner periphery of the through hole and the outer peripheral portion of the stirring member of the stirring screw. While being cut by a shearing action, it is discharged from the through hole and falls toward the bottom of the treatment tank. Also, the relatively fine litter that has risen to the vicinity of the upper end of the stirring member in the cylindrical body bounces back against the stopper, is discharged from the through hole provided in the cylindrical body, and moves toward the bottom of the processing tank. Fall.

  In this way, the egg litter that has been thrown into the treatment tank is repeatedly introduced, lifted, cut, discharged, and dropped into the cylindrical body by the rotation of the stirring screw. Composting and fermentation process will progress, and finally it will be composted. In this case, the egg at the bottom of the treatment tank is efficiently introduced into the cylindrical body by the spiral auxiliary stirring member that rotates in the skirt-shaped guide member, and is lifted up the cylindrical body from the through hole. Since it is cut and discharged, it is possible to pulverize and agitate the raw garbage put into the treatment tank in a shorter time than a conventional garbage disposal apparatus. In addition, the upper end of the cylindrical body is not opened, and the litter that has risen in the cylindrical body is bounced back by a stopper that rotates with the stirring screw, and is discharged and dropped from the through hole. It is not caught in the upper end opening of the slab, and composting by pulverization, stirring process and fermentation process can be performed efficiently.

  Here, if a discharge hole larger than the through hole is provided in a lower portion of the peripheral wall of the cylindrical body than the stopper, the litter that is raised in the cylindrical body and bounced back by the stopper is larger than the through hole. Since it is quickly discharged and dropped from the discharge hole, the circulation of the egg is improved, and the pulverization process can be made efficient.

  Further, if the helical pitch of the stirring member of the stirring screw is gradually decreased upward, the ascending speed of the egg that is raised by the rotation of the stirring screw becomes slower as it goes upward, and is caused by the stirring member and the through hole. Since the shearing action is reliably performed, the overall grinding speed can be increased.

  On the other hand, if a saw blade-shaped cutting portion is provided on the outer periphery of the auxiliary stirring member, the auxiliary stirring member that rotates in the skirt-shaped guide member that is partially opened has a cutting action, so the outer shape is large. Even if it is a lump-shaped egg that cannot be introduced into the cylindrical body as it is, it can be cut and subdivided by the auxiliary stirring member and introduced into the cylindrical body, and the crushing ability is improved.

  Further, the shape of the through hole may be a water droplet shape whose inner diameter is gradually reduced upward. The litter sandwiched between the outer peripheral portion of the stirring member of the stirring screw and the inner periphery of the through hole of the cylindrical body is pushed up by the stirring member, but eventually the inner diameter of the through hole gradually reduced in diameter upwards. Since it is in a state of being gripped so as not to escape, it is surely cut and pulverized by the stirring member, and the pulverizing ability is improved.

  Further, if a scraping member that rotates along the outer peripheral surface of the guide member with the rotation of the stirring screw is provided, the litter may stay on the outer peripheral surface of the skirt-shaped guide member that is partially open. It is possible to prevent the occurrence of troubles such as poor grinding and composting due to adhesion and solidification.

  According to the litter processing machine of this invention, the thrown litter can be grind | pulverized and stirred for a comparatively short time, and composting by a fermentation process can be performed efficiently.

  As shown in FIG. 7, a rotating member 14 that rotates along with the stirring screw 12 is attached in the radial direction of the processing tank 1 near the lower end of the main shaft 12 a of the stirring screw 12, and near the center of the rotating member 14, A scraping member 15 that rotates together with the agitating screw 12 is attached along the outer peripheral surface of the guide member 13b, and a disk-like spacer 12g is attached below the joint portion between the turning member 14 and the main shaft 12a. As shown in FIG. 8, the turning member 14 is provided with an inclined surface 14 a having a wedge shape toward the rotation direction R of the stirring screw 12.

  As shown in FIGS. 6, 7, and 9, the auxiliary stirring member 12 c that is spirally expanded along the inner surface of the peripheral wall of the guide member 13 b is connected to the lower end 12 h of the stirring member 12 b of the stirring screw 12. A plurality of saw blade-shaped cutting portions 12s are provided on the outer periphery of the auxiliary stirring member 12c. As shown in FIG. 6, the guide member 13b is provided with a plurality of through holes 13d having a water droplet shape. On the outer peripheral surface of the main shaft 12a between the upper end portion 12i of the stirring member 12a of the stirring screw 12 and the stopper 12d, a flat blade plate 12e is attached in parallel to the axial direction of the main shaft 12a.

  As shown in FIGS. 10 and 11, a plurality of water-drop shaped through holes 13 c are formed in the peripheral wall of the cylindrical body 13, and a stopper 12 d (for the stirring screw 12 disposed in the cylindrical body 13). A plurality of discharge holes 13f larger than these through holes 13c are opened at a lower position than that shown in FIG. These discharge holes 13f are substantially quadrangular with rounded corners, and are opened in a portion located outside the rotation region of the blade 12e that rotates together with the stirring screw 12. In addition, as shown in FIG. 11, the cylindrical body 13 has a plurality of through holes 13c and discharge holes 13f formed in a metal plate 13p, and the side edges are welded to each other by bending the plate 13p into a cylindrical shape. Can be formed.

  Next, how to use the egg processing machine 10 will be described. When using the egg litter processing machine 10 of the present embodiment, an appropriate amount of a fermentation promoting material in which fermented microorganisms are seeded is stored in the processing tank 1 in advance. In this state, after opening the open / close door 5b of the processing tank 1 and charging the waste to be processed from the input port 5a and closing the open / close door 5b, the switchboard 6 is operated to rotate the motor 9, In the cylindrical body 13 and the guide member 13b, the stirring member 12b and the auxiliary stirring member 12c are rotated in the rotation direction R together with the main shaft 12a, and the turning member 14 is turned in the rotation direction R in the region immediately above the bottom 1a of the processing tank 1.

  Accordingly, the egg thrown into the treatment tank 1 is moved in front of the guiding member 13b by the spiral auxiliary stirring member 12c rotating in the skirt-shaped guiding member 13b together with the stirring screw 12 rotating in the cylindrical body 13. It is introduced into the cylindrical body 13 from the lower end opening 13g of the cylindrical body 13 via the opening portion on the side, and rises in the cylindrical body 13 by the rotation of the stirring screw 12. The litter rising in the cylindrical body 13 is pushed out from a plurality of through holes 13c provided in the peripheral wall of the cylindrical body 13. At that time, the lump-shaped litter is separated from the inner peripheral portion of the through hole 13c. While being sandwiched between the outer peripheral portion of the stirring member 12 b of the stirring screw 12 and being cut by the shearing action, the screw is discharged from the through hole 13 c and falls toward the bottom 1 a of the processing tank 1. Also, the relatively fine sludge that has risen to the vicinity of the upper end portion 12i of the stirring member 12b in the cylindrical body 13 bounces back against the stopper 12d, and is guided toward the outer periphery by the rotation of the blade 12e. It is discharged from a discharge hole 13 f opened at the top of the body 13 and falls toward the bottom 1 a of the treatment tank 1.

  If such an operating state is maintained, the egg thrown into the treatment tank 1 repeats introduction, ascent, cutting, discharging, and dropping into the cylindrical body 13 by the rotation of the stirring screw 12. With the passage of time, the eggplant becomes finer and fermented, and finally composted. In this case, the egg in the bottom 1a in the treatment tank 1 is efficiently introduced into the cylindrical body 13 by the spiral auxiliary stirring member 12c rotating in the skirt-shaped guide member 13b. Since it is cut and discharged from the plurality of through-holes 13c while ascending the inside, it is possible to pulverize the egg litter introduced into the treatment tank 1 in a relatively short time.

  Further, since the stopper 12d is arranged in a disc shape at the upper end portion of the agitating screw 12, the upper end of the cylindrical body 13 is not opened, and the litter that rises in the cylindrical body 13 is the stopper 12d. And is discharged from the discharge hole 13f by the rotation of the blade 12e and falls. For this reason, the litter is caught in the upper end opening of the cylindrical body 13, and the litter is not gradually accumulated, and the composting by continuous pulverization, stirring treatment and fermentation treatment is efficiently advanced. Can do.

  Further, since a discharge hole 13f larger than the through hole 13c is provided in a portion below the stopper 12d of the peripheral wall of the cylindrical body 13, the inside of the cylindrical body 13 is lifted and bounced off by the stopper 12d. As a result of the waste being quickly discharged and dropped from the discharge hole 13f larger than the through hole 13c, the circulation of the sludge is improved, and the continuous pulverization and the stirring process can be made efficient. In this case, since the vane plate 12e that rotates together with the stirring screw 12 is provided inside the discharge hole 13f, the waste that has reached the position of the discharge hole 13f can be quickly discharged from the discharge hole 13f. .

  Further, as shown in FIG. 7, the spiral pitch of the stirring member 12b of the stirring screw 12 is gradually reduced upward, so that the ascending speed of the litter that is increased by the rotation of the stirring screw 12 is increased upward. Since the shearing action is surely performed by the stirring member 12b and the through hole 13c, the overall grinding speed can be increased.

  On the other hand, since a plurality of saw blade-shaped cutting portions 12s are provided on the outer periphery of the auxiliary stirring member 12c, the auxiliary stirring member 12c rotating in the skirt-shaped guide member 13b partially opened has a cutting action. Yes. Accordingly, even if the outer shape is large as it is, the lump-shaped eggs that cannot be introduced into the cylindrical body 13 can be cut, subdivided and introduced into the cylindrical body 13 by the auxiliary stirring member 12c, and the crushing ability is improved.

  Moreover, since the shape of the through holes 13c and 13d is a water droplet shape whose inner diameter is gradually reduced upward, the outer peripheral portions of the auxiliary stirring member 12c and the stirring member 12b, the inner periphery of the through holes 13c and 13d, and Since the litter sandwiched between the two is pushed up by the stirring member 12b or the like, it is gripped so as not to escape by the inner circumferences of the through holes 13c and 13d gradually reduced in diameter upward, The auxiliary stirring member 12c and the stirring member 12b are surely cut and pulverized, so that the pulverizing ability is improved.

  Furthermore, since the scraping member 15 that rotates along the outer peripheral surface of the guide member 13b with the rotation of the stirring screw 12 is provided, the litter remains on the outer peripheral surface of the guide member 13b or is solidified. Thus, troubles such as pulverization failure, stirring failure or composting failure do not occur.

  In this way, the litter is put into the treatment tank 1 of the litter processing machine 10 and the motor 9 is operated to rotate the agitating screw 12 and the like for a predetermined time, thereby crushing and agitating the litter processing machine 10. The egg can be composted by the action and the fermentation action of the fermentation promoting material in the treatment tank 1. The compost generated in the treatment tank 1 can be discharged from the discharge port 8 by rotating the rotary handle 8a and opening the door 8b. In this case, the compost in the processing tank 1 can be discharged from the discharge port 8 by opening the open / close door 8b while rotating the stirring screw 12 and the like by the motor 9, but the discharge port 8 is higher than the bottom 1a of the processing tank 1. Since it is established at the position, all the compost in the treatment tank 1 is not discharged. Accordingly, the compost containing the fermentation microorganisms necessary for the subsequent processing of the eggplant can be left in the treatment tank 1. In addition, when all the compost in the processing tank 1 is to be discharged, the opening / closing door 7a of the cleaning port 7 opened at the same height as the bottom 1a can be opened and executed.

  Water vapor or the like generated during processing using the litter processing machine 10 can be discharged from the exhaust tube 4 or the exhaust pipe 18. In this case, if a deodorizing means is provided in a part of the exhaust tube 4, it is possible to prevent the odor from diffusing. Further, if a mechanism for automatically injecting a chemical having a deodorizing action is provided in the processing tank 1 during the processing operation, the generation of a strange odor itself can be prevented. In addition, in the litter processing apparatus 10, although the one exhaust pipe | tube 4 is provided, since it is not limited to this, two or more ventilation cylinders can also be provided. In this case, an exhaust fan is provided in one ventilation cylinder to serve as an exhaust path for exhausting the gas in the processing tank to the outside, and the other cylinder using the negative pressure generated in the processing tank by the exhaust fan. Can be an intake path for introducing outside air into the treatment tank. With such a configuration, the discharge of the gas in the treatment tank and the introduction of the outside air into the treatment tank are facilitated, and the ventilation in the treatment tank can be enhanced.

  Next, with reference to FIG. 12, other embodiment regarding a turning member is described. In the embodiment shown in FIG. 12, a turning member 16 that rotates in the same manner as the turning member 14 that rotates as the stirring screw 12 rotates is provided. Since the two swirling members 14 and 16 are provided, the stirring action in the vicinity of the bottom portion 1a in the processing tank 1 is increased, so that the efficiency of the processing process can be improved.

  The litter processing machine of the present invention can be widely used as an apparatus for fermenting and composting litter such as leftover food from various offices and homes.
