Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for treating organic wastes using a conveyor,

The present invention relates to an organic waste disposal apparatus, and more particularly, to an organic waste disposal apparatus using a conveyor.

Organic waste such as food waste discharged from homes and restaurants, organic wastes generated at industrial sites, fossil fuels generated from housing, and flour can cause serious environmental problems in soil and rivers when discharged without treatment.

According to the conventional method, a method of recycling organic wastes as livestock feed or compost through a specific process, a method of landing in a certain area or dumping in the sea has been mainly used. In this case, there is a problem that the economical efficiency is low in terms of installation cost and maintenance cost of the processing apparatus. In addition, when the effluent is directly used as feed, adverse effects such as the occurrence of killing are large, and in the case of composting, there are problems such as re-heating and unbalance of unavailability.

In order to solve the above problems, an organic waste treatment system has been developed using organisms such as earthworms and housefly larvae. In this case, it is known that the discharged foliar soil is excellent in non-efficacy and can be useful for cultivation of agricultural land, horticulture, orchard and the like, and plays a role of increasing plant growth and yield of the product.

Among these, the period from egg to adults is 37 to 41 days, and the period of larvae that act as decomposers is about 14 days. The larvae of Donghae have a habit of crawling out to find a dry place to become a pupa after a period of time (about 14 days) in which organic wastes can be decomposed. When 5,000 larvae were injected to 10kg of food waste, more than 80% of food waste was decomposed within 5 days. The volume of food waste was about 42% and 70% less than that of larvae. It is much more effective to nurture and utilize the larvae because the larvae of Donghae are longer than those of earthworms or houseflies.

Techniques for treating organic wastes by using larvae in a duck and the like are disclosed in Korean Patent Publication No. 2010-0003710 (produced by Dong-Ae et al.), Korean Patent Publication No. 2009-0121779 (continuous organic waste disposal apparatus using a larva) .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

FIG. 1 is a side view of an apparatus for treating organic wastes using a conveyor according to an embodiment of the present invention, FIG. 2 is a side view as seen from FIG. 1, and FIG. 3 is a plan view as seen from FIG. 1 to 3, the processing container 100, the discharge portion 108, the connection pipe 109, the roller 120, the roller driving portion 125, the belt 130, the blocking portions 134a and 134b, And a leg portion 140 are shown.

The present embodiment is characterized in that a plurality of processing vessels are moved using a conveyor belt so as to contain organic waste. That is, this embodiment is characterized in that a plurality of processing vessels are placed on a conveyor belt and moved to a position where the organic wastes can be received, thereby distributing an appropriate amount of organic wastes to a plurality of processing vessels.

In the present embodiment, various larvae can be used for ingesting and treating organic wastes. Hereinafter, the present embodiment will be described focusing on embodiments in which organic wastes are treated by larvae.

The organic wastes 102 in this embodiment include organic wastes such as food wastes discharged from households, restaurants, organic wastes generated at industrial sites, fodder generated from housing, and flour.

The processing vessel 110 accommodates organic wastes therein, and is provided with a space in which larvae can dwell. The extent and depth can be determined by the size of the overall organic waste treatment system, the amount of organic wastes that can be treated, and the number of larvae.

The processing vessel 100 may have a three-dimensional shape in which the side face is perpendicular or inclined to the bottom face and the top face is opened. When the side surface of the processing container 100 is inclined with respect to the bottom surface, the inclined surface may be inclined from the corner where it meets the bottom surface, or may be inclined by a predetermined length perpendicular to the bottom surface without inclining at the bottom. In the latter case, the organic wastes and the fecal soil produced therefrom are accumulated at the bottom, and larvae may be located at the upper part.

In the case of the processing container 100 which is inclined from the corner where the inclined surface meets the bottom surface, since the side inclination angle is smaller than the same depth, the collecting rate of the larva can be higher. In other words, when the processing vessel 100 grows larvae in the inside of the process vessel 100 and the large larvae come out to the outside to form a pupa, the smaller the inclination angle of the side, the better the larvae can come out.

Although the plane of the processing vessel 100 is shown as being square in the figure, the present invention is not limited thereto, and the plane of the processing vessel 100 may be circular, oval, polygonal, or the like.

The inclination angle formed with the bottom surface of the inclined surface can be 10 to 80 degrees so as to enable efficient collection without being steep so that the larva can rise to the back. Collecting amount, advantages and disadvantages of larvae according to the angle formed between the inclined surface, the conveyor part, and the bottom surface of the processing container 100 will be described as follows. Small angles can collect large amounts of larvae, but they have a drawback in that they take up a lot of space because they require large vessels.

Automatic collection is easy Homeless larva collecting department
Spacious (occupies a lot of space) Applicable 2 20 96 Homeless larva
Automatic collection is easy Large collection of homeless larvae (large space occupation) Applicable 3 30 95 Homeless larva

Automatic collection is easy Homeless larvae collecting section is small (small space) Applicable 9 90 30 Homeless larvae collecting section is small (small space) Homeless larva
Automatic collection is difficult No Effectiveness

As shown in Table 1, the collection amount, advantages and disadvantages of the larvae according to the inclination angles are shown. When the angle is less than 80 degrees, the collection amount surges to more than 88%, and when the collection amount is less than 70 degrees, 90% or more occurs. Therefore, when the angle of the inclined plane is set to 10 to 80 degrees, larval collecting is possible in terms of collection amount and volume.

Further, according to another embodiment, the side surface of the processing container 100 may be formed as a vertical surface perpendicular to the bottom surface. In this case, when the height of the organic waste is smaller than the vertical length of the vertical plane, the larva can not move and escape along the vertical plane, so that the organic waste can be sufficiently ingested to produce the fecal soil. Here, the fecal soil is an effluent produced by taking organic wastes from larvae such as Donga, and can be used as compost.

The conveyor portion of the present embodiment may be a mechanical device for conveying a material or an article continuously at a predetermined distance, for example, a belt conveyor, a roller conveyor, a trolley conveyor, a wheel conveyor, or the like. Hereinafter, an embodiment of the present invention will be described, focusing on the case where the conveyor section is a belt conveyor.

The conveyor portion may include a roller 120, a roller driver 125, and a belt 130. That is, the roller 120 physically contacts and rotates with the belt 130 carrying the processing container 100 thereon, thereby transferring the belt 130. The roller driving unit 125 is provided at both ends of the roller 120 to rotate the roller 120. The size and the number of the rollers 120 may vary corresponding to the size of the processing container 100 or the configuration of the conveyor portion.

According to another embodiment, the rollers 120 may rotate in contact with each other in the transverse direction and may not be provided with a separate belt 130. That is, a plurality of the rollers 120 are located on the lower surface of the processing container 100, and the organic waste 102 can be rotated to engage with each other such that the organic waste 102 does not fall down or flow. In addition, a conveyor portion implemented in various manners can be applied to this embodiment.

The present embodiment may further include a container cover for covering the processing container 100. [ The container lid can cover the upper surface of the processing container 100 to increase the temperature and humidity inside thereof. That is, when the container lid is covered, it may be an optimal condition for the larva to grow well to the inside temperature and humidity of the processing container 100. The container lid may be combined with a lamp, heater, etc. to adjust the internal temperature and humidity of the processing container 100.

The discharge portion 108 is located on the other side of the processing vessel 100, that is, above the open side, and is used to discharge the organic waste to the processing vessel 100. The discharge portion 108 may be referred to as an input portion. The discharge unit 108 is a device for injecting the organic waste transferred from the connection pipe 109 connected to the predetermined organic waste input apparatus into the processing vessel 100. The discharge portion 108 discharges organic wastes into the processing vessel 100 while discharging or moving the organic wastes to the processing vessel 100 in a fixed state.

In the former case, the discharge unit 108 discharges the organic waste to the processing vessel 100 in a state where the conveyor unit is stopped, and the organic waste can be discharged to the adjacent processing vessel 100 when the conveyor unit is driven. The amount of organic wastes discharged into one processing vessel 100 can be predetermined in correspondence with the receiving space of the processing vessel 100. In the latter case, the discharge unit 108 can discharge organic wastes for each of the plurality of processing vessels 100 while moving.

The discharge portion 108 can be controlled to be discharged by an discharge control portion (not shown) programmed to discharge the organic waste in accordance with the larval growth period of the larvae or the like. It usually takes four days to five days in the egg state, 14 days in the larval state, 14 days in the pupa state, and five to eight days in the adult state. Therefore, the discharge control unit can control the discharge unit 108 so as to inject new organic waste into or around the 14th day after the larva is introduced into the household.

The larva can be put into the treatment vessel 100 before the organic waste is discharged, or may be injected after the organic waste is discharged. The larvae of a male or female can be provided with a separate larva injecting part and mechanically injected into the treatment vessel 100 or a person can manually inject it using a human force.

Referring to FIG. 2, the blocking portions 134a and 134b are provided at the lower end of the conveyor portion, and block the organic waste adhered to the conveyor portion when the conveyor portion is driven. The second blocking portions 134a and 134b are disposed in close contact with the belt 130 when the belt 130 is moved and scrape off organic wastes adhering to the belt 130 to block the movement of the organic wastes. As described above, in order to realize such a structure, a support (not shown) for operating the second blocking portions 134a and 134b may be separately provided. For example, the second blocking portions 134a and 134b can be supported by the legs 140 coupled to the legs 140 at both ends in the direction of leaving the paper surface of Fig. 1 and in the direction of entry, and at the bottom of the conveyor portion.

The present embodiment may further include a heater (not shown) for controlling the temperature. The heater is attached to the conveyor portion or the leg portion 140 to function to raise the temperature. In other words, the larvae live most at 50 ° C to 60 ° C but before or after 35 ° C to 45 ° C. Accordingly, the temperature of the processing vessel 100 can be adjusted so that the larvae actively act on the human body even in the winter. In addition, the heater may move the larva to a predetermined position by increasing the internal temperature of the processing vessel 100, and collect only the larva from the processing vessel 100, such as from the processing vessel 100.

According to another embodiment of the present invention, a lamp may be provided on the upper and side surfaces of the processing vessel 100 to prevent the larva from escaping to the outside of the processing vessel 100, It is possible.

Differences from the above-described embodiment will be mainly described.

The present embodiment is characterized in that the above-described conveyor portion has a structure in which a plurality of layers are formed. In other words, since the conveyor portion for loading the processing container is formed not in a single layer but in a plurality of layers vertically, it is possible to treat larvae and organic wastes in more homosexuals because more processing vessels are handled than in the above embodiment.

The first conveyor part includes a first roller 121, a first roller driving part 125a and a first belt 131. The second conveying part includes a second roller 122, a second roller driving part 125b, And the third conveyor portion includes a third roller 123, a third roller driving portion 125c,

For convenience of description, the identification codes from the lowest layer to the upper layer are named as first, second, and third, but the present invention is not limited to this name.

In the conveyor portion of the upper layer, an injection hole 136 for passing the organic waste between the processing vessels is formed. That is, the second belt 132 and the third belt 133 are provided with injection holes 136 for passing organic wastes into the processing vessel of the lower layer. The injection holes 136 may be formed in various ways, for example, a plurality of injection holes may be formed in one belt, or two belts may be wound around the rollers so as to pass the organic waste therebetween Holes may be formed.

The discharge unit 108 is located above the uppermost conveyor unit, and organic waste can be introduced into the first processing vessel 101 via the injection holes when the first conveyor unit and the second conveyor unit stop. In this case, the discharge unit discharges the organic waste to the processing vessel in a stopped state, discharges a preset discharge amount to the second processing vessel 102, and then discharges the first processing vessel 101 after moving the first conveying unit and the second conveying unit. A predetermined amount of emission can be discharged. Such a structure may be applied to the second conveyor portion and the third conveyor portion in the same structure, and the above-described embodiments may be applied to three or more layers.

7 is a side cross-sectional view of an organic waste disposal apparatus using a conveyor according to another embodiment of the present invention. 7, a processing vessel 100, a frame 710, a rotation unit 720, a conveyor unit 730, and a discharge vessel 740 are shown. Hereinafter, differences from the above-described embodiment will be mainly described.

The present embodiment is characterized in that the processing container 100 is rotated to separate the organic waste and the larva treated therewith. That is, the present embodiment can separate the processing larvae from the organic waste by extracting the processing vessel 100 from a specific region of the conveyor portion, rotating the processing vessel 100, pouring the contents thereof, and then turning the larvae into pupae.

The frame 710 is a frame for supporting the organic waste disposal apparatus of this embodiment. The conveyor portion 730 and the processing vessel 100 are located on the frame 710 and the processing vessel 100 moves according to the operation of the conveyor portion 730. [ As shown, a total of four layers of conveyor portions 730 are implemented, and the conveyor portion 730 of each layer moves the processing vessel 100 where the larvae process the organic waste.

The rotation unit 720 rotates 180 degrees in a state where the processing vessel 100 is engaged and discharges the contents of the processing vessel 100 to the discharge vessel 740. The rotating part 720 may be positioned in connection with the frame 710 separately from the respective conveyor parts 730. Although the rotating portion 720 is positioned adjacent to the conveyor portion 730 of the lowest layer, the present embodiment is not limited thereto. For example, when the rotating portion 720 is disposed on the conveyor portion 730 ≪ / RTI > or may be moved to and located in each layer. In the latter case, a moving means for moving the rotating portion 720 by layers may be separately provided. The moving means may include a rotating means such as a motor such as an elevator, a rotation controlling portion for controlling the rotation of the rotating means, And the rotation unit 720 can move to each layer by being coupled to the chain.

The processing vessel 100 of each conveyor unit 730 is transferred to the rotating unit 720 by a predetermined moving means at the end of the processing of the organic waste and the processing vessel 100 transferred to the rotating unit 720 The upper surface rotates toward the lower discharge container 740 in accordance with the rotation of the rotation part 720 in a state of being coupled to the rotation part 720.

Here, the predetermined moving means may be implemented in various structures, for example, a robot arm-shaped control device that picks up a specific processing container 100 and places it on the upper surface of the rotating portion 720.

According to another embodiment, the conveyor portion 730 of each layer rotates a circular or elliptical path, and pushes the processing container 100 at a specific position in the path from the path toward the rotating portion 720, (Not shown) for positioning the rotary unit 100 on the rotary unit 720. [ The pushing means is a predetermined structure which is normally not located on the path along which the processing vessel 100 moves and is projected along the path at the time when the processing vessel 100 is moved to the rotating portion 720 to move the processing vessel 100 . In this case, the push means is a push structure that pushes and moves the process container 100. When the push structure controls the movement of the push structure to move the process container 100 to the rotation portion 720, And a pushing control unit for pushing in the lateral direction and positioning it on the rotation unit 720.

The present embodiment may also include a reverse pushing means (not shown) for positioning the processing container 100 on the rotating portion 720 again on the conveyor portion 730. The reverse pushing means may include a push structure and a push control portion to move the processing vessel 100 to the conveyor portion 730 at a point and at a time when the processing vessel 100 is positioned on the conveyor portion 730 have.

When the processing vessel 100 is positioned on the rotation unit 720, the processing vessel 100 can be coupled with the rotation unit 720 without falling. For example, the rotation unit 720 may extend in a direction perpendicular to the tangent of the rotation direction and may be connected to the processing vessel (not shown). In this case, 100 may be supported on the upper surface thereof. In this case, the processing container 100 may not be separated from the rotation unit 720 even when the rotation unit 720 rotates. According to another embodiment, the processing container 100 and the rotation unit 720 may be coupled by the magnets of different polarities coupled to the center of each device, They can be combined so as not to be separated from each other by rotation through the structure.

Organic wastes and larvae contained in the processing vessel 100 along with the rotation of the processing vessel 100 are accommodated in the discharge vessel 740 and the discharge vessel 740 may have a structure for isolating larvae from the organic wastes to be pupae have. For example, the side surface of the discharge container 740 may include an inclined surface inclined to the bottom surface such as the inclination angle of the above-described container. In this case, the angle formed by the inclined surface with the bottom surface may be 10 to 80 degrees. Under these conditions, the larva can crawl out of the discharge vessel 740 by itself to be fused. The larva discharged to the outside of the discharge container 740 may be collected in a predetermined collecting container (not shown), and the present embodiment may separately include a transfer path between the discharge container 740 and the collecting container.

The organic waste discharged into the discharge vessel 740 can be maintained at a predetermined humidity and temperature condition, in which case the larva can be induced to move outward. In other words, the larvae of Donghae have a habit of moving in search of cool and dry conditions before they become pupae. Therefore, only the larva can be collected from the discharge container 740 by increasing the temperature and humidity of the discharge container 740. In this case, the desired effect can be obtained when the temperature is from 35 캜 to 45 캜.

In addition, according to another embodiment of the present invention, the apparatus may further include a vacuum transfer unit for sucking the organic waste contained in the processing vessel 100 into a vacuum and transferring the organic waste to the disposal processing area, The contained organic waste may be scraped off and dropped into the discharge vessel 740.

According to another embodiment of the present invention, a conveying mechanism for conveying the processing vessel 100 to the conveying portion 730 and the conveying mechanism 720 for conveying the processing vessel 100 to the rotating portion 720 and the conveying portion 720, And may further include an input unit for inputting the organic waste into the processing vessel 100 using the same mechanism.

Hereinafter, an experimental example of the apparatus for treating organic waste according to an embodiment of the present invention will be described with reference to specific data. Experimental examples are based on food wastes among organic wastes treated by larvae in Donghae and others in each treatment vessel. The effect of treating food wastes by larvae on the wastewater and the usefulness of larvae on the wastewater are explained.

Table 2 shows the concentrations of ammonia gas generated during the decomposition of food waste in the control and treatment groups.

                (Unit: ppm) division Day 1 Day 3 Control Treatment 1 Treatment 2 Control Treatment 1 Treatment 2 ammonia 1.4 100.7 113.9 203.4 424.9 386.7

The control group consisted of a combination of food waste and sawdust, the treatment group 1 was a combination of larvae such as food waste, sawdust and budding, and the treatment group 2 was a combination of larvae and microorganisms such as food waste, sawdust, Here, the input microorganism is yeast, the number of larvae is 5,000, the food waste used is 10kg per day, and the sawdust functions to control moisture and fermentation. The size of containers used for control and treatment was 1,200 mm * 600 mm * 200 mm.

The concentrations of ammonia in the initial food wastes were 1.4 ppm in the control, 100.7 ppm in the treatment 1, and 113.9 ppm in the treatment 2 on the first day, except for the control. On the third day, ammonia was generated at 203.4 ppm in the control, 424.9 ppm in the treatment 1, and 386.7 ppm in the treatment 2.

This difference in concentration indicates that the food of treatments 1 and 2 is more rapidly degraded than that of the control, which is influenced by larvae such as Dongae. The occurrence of ammonia due to the fermentation and the modification of the physical properties of the food when it was decomposed by the larvae was relatively high in the early stage of the treatment.

Especially, in Dongae, etc., larvae can not be inhabited in winter, so the structure is made to be able to regulate the temperature and humidity in four seasons. In order to suppress ammonia generation, it is necessary to perform sterilization purification and chemical reaction of electric or electronic, It is possible to add a generalized system capable of suppressing the occurrence of ammonia such as a heat exchange air conditioning system.

In addition, since the fecal soil discharged by the embodiment of the present invention is excellent in non-efficacy, it is possible to analyze the components of the conversion product obtained from the food waste, which can be usefully used for the cultivation sites of agricultural lands, crops (horticulture, fruit trees, special crops, Table 3 shows the results.

Control 1 is a combination of food waste, control 2 is a combination of food waste and sawdust, T1 is a combination of larvae such as food waste, sawdust, and tortoise, and T2 is a combination of larvae and microorganisms in food waste, sawdust, T1-1 and T1-2 are experimental examples of T1, and T2-1 and T2-2 are experimental examples of T2.

As a result of analyzing the composition of the fecal soil, which is the decomposition product of food waste decomposed by the larvae in Donghae, both nitrogen content and total nitrogen (T-N) content were greatly lowered compared to control 1 and 2. The contents of nitrogen (N) and total nitrogen (TN) in the foliar soil from T1 were 30% to 40% and 20%, respectively, compared with the contents of nitrogen (N) and total nitrogen (TN) % ~ 30%, which means that it has better ingredients as fertilizer.

Also, the same results are obtained when larvae and microorganisms are treated at the same time. In addition, the decomposition products of food wastes were acidic in the control 1 and 2, and the decomposition products were changed to neutral or weakly alkaline when they were decomposed using larvae, such that they were suitable for the composting of decomposition products of food wastes. These degradation products can also be used as mushroom culture media.

In addition, the composition of the larvae and the pupae after the treatment of food waste is analyzed, and the results are shown in Table 4 below.

Moisture content is the content in the analysis stage after lyophilization. The crude protein was 43.42%, which was similar to that of soybean meal, and the energy level was very high. In the pupa of Donghae, the results were similar to those of larvae, and were higher in crude fat, crude protein and crude fiber than in larvae. Larvae and pupae can be used for feed animals (pigs, cows, chickens, etc.), reptiles (frogs, etc.) and fish.
