Description

Technical Field

[0001] The present invention relates to an apparatus and method for recycling organic waste.

[0002] Recycling of organic waste is a common and well-known method for fertilizing and preparing arable land, planting areas, and cultivation containers. In most cases, chemically manufactured fertilizers and fertilizer agents are also used, with the aim of stimulating and promoting growth. The drawbacks of these fertilizers are well known and should occur to anyone who reads the package warnings. In this case, the user is warned to avoid contact with and ingestion of the product in any form. Additionally, a notice prohibiting the discharge of substances into drainage and open waters is specified on the package. Finally, and certainly a very threatening warning, is the warning to "keep out of reach of children and animals." Therefore, fertilizer agents are chemicals that are harmful to health and may pollute the environment. To introduce these "hazardous substances" into the soil, electrically operated machinery and irrigation systems that consume energy are used. The present invention departs from this method of assisting the growth of the flora and preparing the soil and proposes an environmentally friendly and sustainable device.

[0003] Accordingly, it is an object of the present invention to provide an organic waste treatment apparatus that operates without the use of chemical additives and without the supply of artificially generated energy.

[0004] This object is achieved by an apparatus for recycling organic waste, comprising at least one receiving container for the organic waste, through which the organic waste is passed to at least one grinding unit, the grinding unit being driven by the influent water.

[0005] For example, organic waste consisting of everyday kitchen waste is placed in a receiving container. In the next step, the soil area is prepared from the perspective of ecosystem and nature conservation. For this purpose, water is supplied to the device from a water inlet. The crushing unit is driven by water pressure, and the organic waste is crushed. In a particular embodiment of the present invention, a part of the crushing unit is in the form of a roller, and the design in the form of at least two rollers that rotate together or in opposite directions is of course also included.

[0006] In a further embodiment of the present invention, the organic waste is conveyed to and pressed against the crushing unit using a conveying device. The conveying device is driven by the existing water pressure in a simple design in the form of a supply pressure (conveying) plate. No external energy supply such as electrical energy is required. Only hydroelectric power is sufficient to drive the device. Of course, since the water contains valuable dissolved components from the crushed organic waste, the water can and should be used for irrigating the soil area to be treated. Therefore, the organic waste is used in the most suitable form, i.e., as crushed fertilizer, just like the water that is the driving means of the device. Therefore, there are no harmful residues.

[0007] The pulverizing unit itself, or a part thereof, may be in the form of a roller. However, there are also non-roller-shaped pulverizing units that can achieve the same purpose. In addition to the effects of squeezing and pressing, they may have cutting edges, knives, blades, or other devices to further perform a pulverizing function. This is already known in principle in the prior art. For example, a roller with a spiral coil is used to better draw in organic matter. The pulverizing units may be arranged adjacent to each other or vertically to create a wider pulverizing area. Therefore, organic waste passes through a plurality of pulverizing units one after another. This can increase the pulverizing speed and effect. Depending on the reinforcement of the pulverizing unit, fine pulverization may be performed after coarse pulverization. The number of pulverizing units arranged adjacent to each other and the number of pulverizing units arranged vertically depend only on the shape of the target system and may be freely selected. This can be particularly easily imagined when the pulverizing unit is in the form of a roller. The individual rollers are arranged adjacent to each other or vertically.

[0008] Therefore, in a preferred embodiment of the present invention, the number and arrangement of the rollers are such that organic waste can be optimally pulverized. In this case, it is advantageous if the device is designed so that the pulverizing unit, particularly the roller-shaped pulverizing unit, can be replaced. Therefore, the pulverizing unit can be adapted to the hardness and type of organic waste. For example, vegetable scraps exhibit different resistance from the shells of nuts. Such adjustment optimizes the pulverizing process and saves time and energy. The replaceability of the individual pulverizing units can be ensured by individually suspending them on a frame designed for this purpose.

[0009] The frame, i.e., the holding module, is designed to be insertable into the receiving container. The frame itself may have an insert and a support surface for placing the grinding unit. The support surface and / or the insert are standardized so that the grinding unit can be placed or pushed in such a way that it fits exactly. Put simply, any grinding unit can be adapted to the frame. In this specification, the individual design of the grinding unit is not important. For example, the grinding unit may be equipped with knives and may be reinforced with hemispherical surface bulges. Alternatively, it has a smooth surface and simply grinds the organic waste. The supply pressure plate not only transports the organic waste to the grinding unit but also serves to compress the organic waste. This compression process is enhanced using a further pressure plate installed on the opposite side of the grinding unit. This increases the holding capacity of the receiving container and thus the overall holding capacity of the device.

[0010] Not only the receiving container and the holding module, but the entire device may also be composed of individual modules. Therefore, the device can be easily incorporated with individual parts and assembled on-site.

[0011] In a particularly preferred embodiment of the present invention, the grinding unit is driven via a turbine. A turbine as a rotary fluid machine is suitable for driving the grinding unit because it can easily receive the inflowing water and directly convert it into mechanical rotational energy. Here, the water pressure can determine the rotational speed of the grinding unit. However, the energy for driving the grinding unit may be supplied from another drive system. The use of hydroelectric power has the advantage that water can be used for irrigation. Therefore, the entire bi-chopper system operates without leaving residues. This also coincides with the basic concept of the inventor who is interested in comprehensively using natural and renewable local raw materials. The reason for the recycling concept is not only that the transport route of the product, the fertilizer, is short, but also the findings of bio-economists that regional organic waste is a better fertilizer than other organic fertilizers, which has become the driving force for realizing such an invention. As long as the regulations on organic waste are complied with, using organic waste as fertilizer is environmentally friendly, especially protecting water areas, not only logically wise but also having excellent fertilizer effects.

[0012] Hereinafter, with reference to the drawings and examples, the arrangement of individual components relative to each other and the functions of the present invention in specific embodiments are shown. This is not intended to be limiting. This is only one possible embodiment of the present invention.

Mode for Carrying Out the Invention

[0015] In Fig. 1, the receiving container 1 for recycling organic waste can be clearly seen. The roller-type grinding unit 6 described in this embodiment is not shown in this figure. However, the opening 2 into which the roller holding module 7 (frame) having rollers is introduced can be seen. The supply pressure plate 3 intended to press the organic waste against the grinding unit 6 can also be seen (roughly hatched). Also, the lateral surface 4 for guiding the supply pressure plate 3 on which the organic waste is transported and pressed against the grinding unit 6 can be seen. Therefore, the structure and arrangement of the individual components of the device according to the present invention, and their interactions, can be clearly understood from Fig. 1. The frame for storing the grinding unit 6 is shown in a separate figure. The base plate is provided here with a water discharge port 5. This embodiment of the present invention shown in this specification has dimensions of H = 250 mm, W = 180 mm, D = 120 mm and has a relatively small receiving container 1 targeted at everyday kitchen waste. However, the same model has also been constructed on a much larger scale with a volume exceeding 5 m 3 and in a very different orientation.

[0016] Figure 2 is a schematic view of a holding module 7 for a grinding unit having a drive unit 8. The drive unit 8 is schematically shown as a tube in this figure. The orientation of the tube in the figure has no relation to the final orientation of the drive unit 8 (turbine). Since the grinding unit 6 is roller-shaped, the frame 7, in this case the roller holding module, can be seen. In Figure 2, only two roller-shaped grinding units 6 can be seen. These are indicated by triangular hatching. However, whether there are two or more grinding units 6 or whether they are roller-shaped is not important for the present invention. If the number of grinding units 6 increases, the grinding area can be increased, or if one is placed under the other, the degree of grinding can be improved. In Figure 2, the grinding unit 6 rotates via a hydraulic turbine 8. Knife-shaped choppers on the roller grind the organic waste. The grinding unit 6, in this case a roller equipped with knife-shaped choppers, is driven via a hydraulic turbine 8. The water pressure is proportional to the rotational speed and the pressure / shearing force acting on the organic waste. Each individual grinding unit 6 can be easily exchanged on the holding frame 7, but other holding modules 7 with separately arranged grinding units 6 can also be inserted into the opening provided for this purpose in the receiving container. This, of course, also applies to holding modules 7 having different numbers of grinding units 6.

[0017] Example of filling and start-up

[0018] In the first step, the organic waste is introduced into the receiving container 1. Analyze the hardness and composition of the organic waste to determine the number and arrangement of the grinding units 6. Although this may sound complicated, it can be done in a few minutes with a little practice. Here, the corresponding holding module 7 with the determined number and arrangement of grinding units 6 is inserted into the opening provided for this purpose in the receiving container. A water inlet is attached so that the turbine 8 can be operated. The water pressure drives the turbine 8 and the grinding units 6 start to move. The water pressure continues to press the supply plate 3 against the grinding units 6 together with the organic waste. Therefore, the supply pressure plate 3, on the one hand, ensures the transportation of the organic waste towards the grinding units 6, and on the other hand, also provides the pressure for pressing the organic waste against the grinding units 6. The organic waste is cut into small pieces. In the process, the inflowing water absorbs valuable suspended particles from the organic waste. This water rich in suspended matter is used for irrigating seedbeds, fields, or other cultivated lands. For this purpose, water can be poured out from the outlet fixed by the closure. The closure can be designed as a slider. The finely cut and ground organic waste is taken out from the receiving container 1 and can be immediately used for fertilization purposes. It is stated here again that only water and waste are used to produce the fertilizer. The organic waste may preferably consist of residues or waste generated during food preparation. As already mentioned, these residues from local sources are particularly effective fertilizer agents. Biocompatibility will probably play a decisive role.

[0019] A further practical improvement includes the installation of an automatic water inflow stop device that regulates the water supply when the receiving container 1 is empty or full.
