Description

  The present invention relates to a method and apparatus for confining, composting and reducing biodegradable waste, in particular a vertical composting apparatus with discrete treatment areas and composting biodegradable waste using this apparatus. On how to do.

  It is well known to process organic waste using a composting device and systematically decompose it. An increasing number of consumers have unrestrained consumption preferences, and under these pressures, composting devices have been developed and their use is rapidly increasing. Accordingly, understanding of the decomposition process is also progressing. Currently, thermophilic species of anaerobic bacteria that are optimal for degrading organic waste are known to grow only in a very limited range of environmental conditions. Those skilled in the art understand the importance of creating an optimal environment to control several conditions and to promote the degradation process while suppressing the generation of unpleasant odors. Such conditions include compost and ambient porosity, temperature, oxygen level and moisture.

  Strangely, although there is motivation to encourage the development and use of composting equipment, ie organic waste reduction equipment, no consideration is given to reducing the physical space waste required by the composting equipment itself. . In other words, at present, it is common to use a large composting apparatus according to a model that moves waste horizontally during the decomposition process. Such devices are large scaffolds and require a significant area of potentially valuable land. Generally, a composting apparatus is installed in an agricultural area or the like that is far from an urban area. When composting is performed in such a place, it is necessary to transport a large amount of biodegradable waste from the urban area. No large upright composting device is known. The prior art will be exemplified below.

  An early composting method and apparatus is disclosed in USP 4,326,874, invented by Burklin. In this device, compost is produced on a deposition surface, where compost layer strips are juxtaposed with the strip edges adjacent, and at least one layer of compost material is added to the adjacent strips. The hard material is removed and the compost is then deposited by a rake conveyor member that can move up and down. The ventilation device is composed of a ventilation lance that enters and leaves the compost material. Movement of compost material in the apparatus is performed by a belt-type horizontal conveyor.

  For residential areas, composting devices that use horizontally stacked units are known to improve heat containment and ventilation, and to simplify the manual redirection and mixing of stacked compost. It has been. For example, USP 5,190,572, whose inventor is Long, discloses a composting apparatus composed of a plurality of stacked boxes each having four combined double wall panels. Since each box can be fixed to the upper or lower box, the boxes can be stacked at any height, and the stacking order can be easily changed. The device has a lid that covers the top box of the stacked boxes. In use, boxes are stacked between a bottom box and an upper box in a first region of open ground to form a first stack. The biodegradable material is charged into the composting device and decomposition begins. After decomposition, the box stacking order is reversed, and compost is mixed and aerated to accelerate uniform decomposition. When the re-stacking operation is performed, the inside of the compost can be processed.

  Another early device is the device described in US Pat. No. 4,683,674 invented by Faul. This publication discloses a panel for use in a garden compost bin. Nesting is performed horizontally and vertically together with a similar panel to form a cylindrical modular panel structure. As can be readily appreciated from the above description, neither Faul nor Long describe an automatic device suitable for large, high-out compost formation.

  A more suitable apparatus for industrial use is disclosed in US Pat. No. 6,352,855 whose inventor is Kerouac. This gazette discloses an in-vessel composting apparatus that continuously treats food waste to obtain a two-component final product comprising a bulk organic compost material and a liquid component rich in compost. And methods are described. The apparatus is equipped with a shredder / granulator and is fed to a compost bulk collection container via a horizontally arranged drum having at least three chambers with connecting ports of increasing diameter. The drum is rotated by the motor, drained in the first chamber, the batch contents are kept at a high temperature for a predetermined time, and then this is percolated to the final compost product in the third chamber, the final chamber, Obtain liquid compost rich in nutrients. This apparatus is only intended for the continuous processing of raw material waste and horizontal processing of processing materials in a three-week output cycle consisting of four processes.

  One of the major contributors to continuous composting is Canada's Jack Wright, which has been granted USP 5,846,815, 5,551,969 and 5,409,831 as patents. U.S. Pat. No. 5,409,831 describes a continuous composting device with a horizontally disposed elongated sealed tunnel having a waste input end with a mixing hopper and a discharge end for discharging compost. A high conveyor track consisting of parallel rails with rollers is provided on the tunnel floor along the entire length of the tunnel. A tray row of conveyor trays runs on the track and moves the compost. Each tray has a replacement frame and a perforated substrate for aerated compost. The ram presses the most upstream tray, and the upstream tray moves downstream relative to the preceding tray row to move all tray rows. The aeration means forces air into the gap between the tunnel floor and the conveyor tray so that the air rises through the tray substrate and the compost. A mixing roller with a paddle is extended on the side of the tunnel to mix the garbage. The tunnel outlet is fitted with a pressure-closed hinged door that is always open by the moving conveyor tray.

  USP 5,551,969 discloses an improved version of the apparatus of USP 5,409,831. In this improved type, a blending trough is added to the dust inlet, and a water charging means for adding water immediately after mixing by the mixing roller is added.

  Also, the device of USP 5,846,815 is an improved version of the device disclosed in USP 5,551,969 and USP 5,409,813. Utilizing the same horizontally positioned tunnel with substantially the same scaffold and utilizing the same mechanical means to move the compost material, the composting device is divided into treatment areas. Each processing area includes a self-contained ventilation unit that minimizes the exchange of air between the processing areas. If the apparatus has only two processing areas, the first self-contained venting unit vents the upstream composting area, recirculates a portion of the venting gas within the upstream area, and the second self-contained venting The unit vents the downstream composting region and recirculates a portion of the aeration gas within the downstream region. Each composting area may consist of a plurality of chambers with self-contained ventilation units. Further, the upstream region and the downstream region may be separated by an intermediate region where they are combined to minimize the exchange of air between the regions. All of Wright's devices are large and complex horizontal devices that are expensive to manufacture. Furthermore, the ventilation unit in the device described in USP 5,846,815 is not optimal in that it supplies air only to the underside of the compost rather than injecting air into the stacked compost. That is, the air flow in the majority of the waste becomes insufficient and the aerobic property becomes low.

  Finally, USP 6,171,852, whose inventor is Bright, discloses a composting apparatus having a horizontally disposed composting bay having an input end and a discharge end. A transport device at the bottom of the bay receives the waste, and transports the waste from the input port to the discharge end along the entire length of the bay. The device has a movable fluid distribution cell with a fluid injector that injects water and air into the waste while transporting the waste.

Each of the above publications reflects the current situation that the present inventor currently recognizes. The intent mentioned in these publications and the intent of summarizing the content disclosed in these publications is to fulfill the obligation of disclosing appropriate information for examination of the claims of this application. In addition, none of the publications disclose, teach, suggest, nor indicate the invention disclosed in the present specification and described in the claims, alone or in combination. Nor is it self-evident.

  Hereinafter, FIGS. 1 to 8 will be described. The same reference numerals denote the same constituent members. FIG. 1 is a front perspective view including a partial cross-section showing a first preferred embodiment according to the present invention. 2, 3 and 4 are a transverse rear view, a transverse side view and an axial transverse sectional view of the first embodiment, respectively. The device 100 of the present invention shown in these figures is composed of an upright housing 110 having at least one housing wall 120 in its most essential form. In order to compost the waste according to the present invention, it is preferable to form the container as a whole in a cylindrical shape and form the container wall as a single wall or a continuous wall, or as a whole as a cubic shape, It is preferable to form with four side walls. In the first preferred embodiment, the container housing is formed in a cubic shape and supported by the frame 130. The container dimensions vary depending on the scale of the composting process, but about 9 to 18 m (30 to 60 feet) is the most effective for the height, and it is processed with a typical resonance time in an extrusion flow type apparatus. It is suitable for the waste material.

  The waste input port 140 is provided in the upper part of the housing on the upper processing region 150. This inlet may be provided directly above the upper processing area, or may be shifted laterally depending on the means for distributing and spreading the waste prior to introduction into the first processing area. A lower processing area 160 is disposed below the first processing area.

  The leveling means 170 leveles the waste introduced into the housing from the waste input by leveling means 170, preferably comprising at least one auger screw having either a continuous solid thread or a ribbon thread. , Evenly distribute to the upper processing area. For example, any suitable means such as a rotation leveler (as shown in FIG. 8) can be used. When the at least one auger screw is driven by the reversible motor 180, the waste material moves regularly and systematically in each direction along the length of the auger screw.

  At least one upper stirring device 190 is disposed between the upper processing region 150 and the lower processing region 160. The agitation device preferably comprises a first set of juxtaposed rollers 200, 210, each roller having a plurality of surface paddles or bars 220. The rollers are driven by one or more reversible motors 230. When driving, when viewed from either end, the roller rotates in the opposite direction so that the left hand roller rotates clockwise and the right hand roller rotates counterclockwise toward the left hand roller. preferable. Note that each roller may be rotated in the opposite direction as long as both rollers do not rotate in the same direction at the same time.

  In another embodiment, non-stirring devices such as stationary grids, bars, moving beds, sliding gates or hatches may be used instead of the stirring device. In these embodiments, since a device that separates different regions in the composting device is used, the weight of the composting material in the upper region of the composting device compresses the composting material in the lower region of the composting device. Absent. Nevertheless, in these embodiments, although the vertical arrangement is used, the basic concept of the discrete arrangement configuration processing area is not changed.

  In a preferred embodiment of the present invention, a lower stirring device 250 is provided at the base of the lower processing region 160. The stirring device is preferably constituted by a second set of juxtaposed rollers 260 and 270 that operate in the same manner as described above. The second set of rollers is driven by at least one second motor 280.

  Throughout the composting cycle, the agitation means operates at predetermined intervals. Inside the container, a stirring device mixes, deagglomerates, aerates and inverts the compost. In addition, since the agitation means supports the compost on it, the total weight of the stacked compost does not consolidate the underlying compost, so that oxygen is fed deeply into the stacked compost. Nothing will happen. The stirring action can be enhanced by providing one or more buffer plates 240 on the inner surface (s) of the container housing. Alternatively, like the hopper, the wall 290 of the container housing itself may be tapered inward so that the compost stream can be directed to the agitator and directed to the opening at the bottom of the processing area.

In the apparatus of the present invention shown in FIGS. 5 to 7, an intermediate processing area 410 is additionally arranged between the upper processing area 150 and the lower processing area 160. When one or more intermediate processing regions are additionally arranged, it is necessary to provide one or more intermediate stirring devices 420, preferably a third set of rollers 430, 440 and a third motor device 450 accordingly. There is.

  An environmental control device may be provided in order to strictly adjust the conditions for processing the compost material during resonance. As already mentioned, the use of a spray nozzle allows water to be added to a given treatment area. Furthermore, if a temperature sensor, an oxygen level sensor, and a moisture level sensor are provided in one or more processing regions, an undesirable condition can be immediately corrected. These sensors are not shown because they are well used and well known. In addition, a gas exhaust duct 460 may be provided to ventilate and remove exhaust gases exiting the composting process. The exhaust gas may be treated with the biofilter 470 and then released directly into the atmosphere (if appropriate and permissible) or may be discharged to a flat ground. Next, fresh air or recycled air is introduced into the container housing from the air inlet 480. This air can be heated or cooled by a heating / cooling device 490. All of these environmental devices are preferably coordinated with each other and with the agitator by programmed logic means, PLC 500 or a computer.
