Description

Automatic apparatus for treatment of organic waste using BSF larva}

The present invention relates to an organic waste treatment apparatus using insect larvae, and more particularly, to a continuous organic waste treatment apparatus using black soldier fly (BSF) larvae.

At present, organic wastes such as food waste emitted from homes and restaurants, organic wastes generated in industrial sites, and livestock waste and phosphorus from livestock houses can cause serious environmental problems such as soil and rivers if they are discharged without treatment.

According to the conventional method, a method of recycling organic waste to livestock feed or compost through a specific treatment process, a method of landfilling or dumping at a certain area is mainly used. In this case, there is a problem that the economic efficiency is low in terms of installation cost and maintenance cost of the processing device. In addition, when the discharge is used as a feed as a side effect, such as agglomeration is large, there is a problem such as reheating and ineffective imbalance in the case of composting.

In addition, to solve the above problems, organic waste treatment systems have been developed using organisms such as earthworms and housefly larvae. In this case, the discharged fecal soil is excellent in inefficiency, which can be usefully used for cultivating cropland, horticulture, orchard, etc., and is known to play a role in increasing the growth of plants and the yield of products.

Of these, Dongae et al, the length of the eggs to adults is 37 to 41 days, the larvae that act as a decomposer is about 14 days. After a period (about 14 days) when the organic larvae can decompose organic waste, the larvae crawl out to find a dry place to become a pupa. Injecting 5000 larvae into Dongae, etc. in 10 kg of food waste decomposed more than 80% of the food waste in 5 days, and the decomposed food waste was reduced by about 42% in volume and about 70% in weight. It is much more effective to breed and use Dongae et al. Because larvae have longer time to decompose organic waste resources than earthworms or house flies.

However, the organic waste treatment apparatus using an earthworm or a fly has problems such as being applied only to a small amount of organic waste generated at home, odor generated when organic waste decays, and difficulty in separating feces and larvae.

Therefore, larvae in Dongae, etc. can not only process organic waste, but also can be used as animal feed and oil extraction, it is necessary to develop a homeless larvae automatic collection device that can efficiently breed and grow it. Therefore, there is a need for an automated processing apparatus capable of continuously growing larvae in Dongae and developing labor larvae in Dongae, which can automatically collect homeless larvae, thereby reducing labor.

1 is a perspective view of a continuous organic waste treatment apparatus according to a first embodiment of the present invention. Referring to Figure 1, the inclined surface 110 formed on the side of the main body portion, the upper groove 120 of the body portion, the blocking film 130, the driven roller gear 140, the rotary operation unit 150, larva collector 160, transport A roller 170, a fecal collection bin 180 and a body leg 190 are shown.

In dongae, larvae tend to find high dry conditions before moving to sloping high places. Therefore, the main body portion is opened, the inclined surface 110 is formed on at least one side so that the larvae rise up before the pupa, such as Dongae ate enough nutrients from the organic waste.

The body portion may be polygonal (triangular, square, etc.), circular or elliptical in shape. When the circumference of the main body is circular or elliptical, a tapered inclined surface such as a funnel may be formed.

Here, the angle formed between the inclined surface 110 and the bottom surface of the body portion may be an angle at which larvae can move to the dongae along the inclined surface (110). For example, the angle of inclination may be from 10 ° to 80 ° to enable efficient collection without steep to allow larvae to climb on the dongae. Looking at the collection amount, advantages and disadvantages of the larvae in accordance with the angle formed between the inclined surface 110 and the bottom of the body portion as follows. If the angle is small, it can collect a large amount of larvae, but it takes a lot of place because a large container is required.

Table 1. Larvae collection, advantages and disadvantages according to tilt angle

Referring to Table 1, when the angle is 80 ° or less, the collection amount is rapidly increased to 88%, and when the collection amount is 70 ° or less is 90% or more. Therefore, when the angle of the inclined surface 110 is set to 10 ° to 80 ° it is possible to efficiently collect the larvae in terms of volume and volume.

The inclined surface 110 may be formed from the bottom to the top of the main body, or may be formed from the top of the fecal soil in which larvae grow to the top of the main body.

Inside the main body, there is a space where larvae can live in Dongae, where organic waste is put together with larvae in Dongae. The organic waste can be put in after the finely divided or non-degradable elements such as bone are removed. To this end, a system such as a crusher or food waste treatment device may be provided on one side of the organic waste treatment device of the present invention.

An upper groove 120 through which the larvae may be moved is formed on the upper edge of the main body, such as Dongae moving through the inclined surface 110. The inner space of the main body may be divided at predetermined intervals by the blocking film 130. In this case, the discharge hole for discharging the fecal soil to the lower portion of the main body at intervals separated by the blocking film 130 may be formed on the lower surface of the main body. Detailed description thereof will be described with reference to FIG. 3A.

The bottom of the main body is provided with a fecal soil discharge portion for discharging the fecal soil generated when the larvae inhabit the outside. Referring to FIG. 1, the case of fecal soil discharge part is composed of a driving roller (rotation operation part 150 formed at one end of the driving roller) and a driven roller (driven roller gear 140 formed at one end of the driven roller). Detailed description thereof will be described with reference to FIG. 2.

The conveying roller 170 is positioned below the fecal soil discharge part, and conveys the discharged fecal soil in a specific direction. That is, the conveying roller 170 transfers the fecal soil discharged from the lower portion of the fecal soil discharge part to collect fecal soil in the fecal soil collecting container 180 prepared in advance. Therefore, when using the transfer roller 170 there is an advantage that can receive a fecal soil at a specific position.

If the transfer roller 170 is not provided, the fecal soil may be directly received by placing the fecal soil collecting container 180 under the fecal soil discharge part. In this case, the lower part of the fecal soil discharge part is made into a tapered shape in which the cross-sectional area becomes smaller toward the downward direction, and the fecal soil collecting container 180 can be positioned at the lower end thereof to receive fecal soil.

The main body leg 190 supports the main body 100. The fecal soil discharge part and the ground may be spaced by a predetermined interval by the main body leg 190, and thus discharge of the fecal soil toward the ground is possible. In addition, according to another embodiment, the main body leg 190 may be omitted, instead, a fecal soil collection container 180 that can directly receive the fecal soil discharged from the fecal soil discharge unit may be coupled to the lower body portion.

In addition, according to another embodiment, the main body leg 190 may support the main body, and a through hole may be formed therein so that the larvae may be collected in the dongae moving through the upper groove 120. In this case, the larva collector 160 is coupled to one end of the main body leg 190, and the connector for connecting the upper groove 120 and the larva collector 160 separately as shown in Figure 1 may be omitted. .

The larvae collecting container 160 is coupled to the upper groove 120 of the body portion, the larvae are collected in the larvae collecting cylinder 160, such as Dongae moved through the upper groove 120 of the body portion.

In addition, according to another embodiment, the inclined groove connected to the upper groove 120 may be inclined on the side of the body portion rather than the inclined surface 110. For example, when the inner side of the body portion is not the inclined surface 110, the inclined groove having a width enough to pass through the larvae can be formed on the side other than the inclined surface. The inclined groove may form a predetermined angle with the bottom surface of the main body, such as the inclined surface 110, this angle may be an angle to enable efficient collection without being steep so that the larvae can rise in the Dongae. Even when the inclined surface 110 is not formed in the main body, the larvae may be collected through the inclined grooves.

2 is a perspective view of a fecal discharge part of the continuous organic waste treatment apparatus according to the first embodiment of the present invention. Referring to FIG. 2, the driving roller gear 210, the helical blade 215, the driven roller gears 220 and 140, the driven roller shafts 225 and 145, and the rotation operation unit 150 are illustrated. The differences from the above will be explained mainly.

The drive roller gear 210 is coupled for driving with an adjacent driven roller gear 220. Here, the coupling method may be various, for example, it may be a coupling coupling, rolling coupling and the like.

In addition, the plurality of driven roller gears 220 and 140 are also engaged with each other. The rotation manipulation unit 150 is coupled to one end of the driving roller gear 210. The rotation manipulation unit 150 is a means for rotating the driven roller about an axis by a user's manual or control system.

In FIG. 2, a circular rotation manipulation unit 150 is illustrated, but is not limited thereto. For example, the rotation operation unit 150 may also be a lever, it can be applied to the present invention if it is a shape that can rotate the driven roller.

In addition, the rotation manipulation unit 150 may be manually operated and rotated by a user, or may be rotated by an electronic or automatic control device. For example, by connecting a timer for measuring time to the rotation operation unit 150, a motor for driving the rotation of the rotation operation unit 150, and a control unit for controlling the rotation of the motor at regular intervals, the rotation operation unit ( The fecal soil may be discharged by rotating 150).

The helical blade 215 rotates helically to wave in the gear direction when the driving roller gear 210 rotates. This helical blade 215 is formed on the drive roller and the driven roller. Therefore, the fecal soil generated by the helical blade 215 is discharged from the main body portion to the bottom when the driving roller and the driven roller rotated by the driving of the rotary operation unit 150.

The shape of the helical blade 215 does not necessarily need to be integrally formed. For example, a groove may be partially formed in the middle of the helical blade 215, or a pin having an array of helical blades formed on the axis of the roller may be included in the helical blade 215 described in the present invention.

Hereinafter, with reference to Figure 3a will be described the operation of the continuous organic waste treatment apparatus according to the first embodiment of the present invention. 3B is a correlation graph of temperature and time formed during operation of a continuous organic waste treatment apparatus.

First, the larvae 310 are introduced into Dongae, etc. on the upper portion of the organic waste 320 accommodated inside the body part 100 by the user. The larvae 310 in Dongae, etc. are collected in the larvae collecting container 160 after the organic waste 320 is decomposed and moved along the inclined surface 110 to become a pupa.

Thereafter, the fecal soil generated from the organic waste 320 is discharged to the discharge hole 350 formed at the bottom of the main body by the helical blade 215. Here, the discharge hole 350 may be formed at the end of the direction moving by the helical blade 215 in each zone divided by the blocking film 330. When the helical blade 215 is discharged while pushing the fecal soil in a specific direction, the fecal soil may not be evenly discharged. In this case, the fecal soil may be discharged to the lower portion of the main body at predetermined intervals by using the barrier film 330. Make sure The discharge hole 350 may be formed under the blocking film 330. In this case, the bottom surface of the main body portion can prevent feces leaking between the furrows formed in the helical blade 215, that is, the blades, and can discharge the fecal soil only at the position where the discharge hole 350 is formed.

The heater 360 is attached to the side of the main body 100 to increase the edge temperature of the main body 100 cooled by the ambient temperature. To explain the need for this, the larva 310 in Dongae etc. is active even at 50 ° C to 60 ° C, but most actively live before or after 35 ° C to 45 ° C. When the temperature rises to about 50 ° C., the larvae 310 in the dongae tend to move to external access points D, E having a low temperature, which is a good point to act.

The external access points (D, E) are relatively low in temperature because they are in contact with the outside and are shown in FIG. 3B. When the temperature of the central portion F rises, the larvae 310 move to the larvae treatment zones A, B, and C and the external access points D and E. When the larvae 310 move to the external access points (D, E), such as Dongae fall into the fecal discharge portion or discharge hole 350 or may be a problem that the ratio of the larvae collected in the collecting container 160 is reduced. Therefore, the heater 360 may increase the temperature of the external access points (D, E) to block the larvae 310 from coming to this point. The heater 360 may be attached to the inner or outer circumference of the body portion 100 in a continuous shape as a whole, or may be partially attached.

The heater 360 may be adjusted to the temperature of the main body 100 because the ambient environment is below freezing in the winter and the larvae 310 do not work in Dongae, so that organic waste treatment cannot be performed.

In addition, the temperature blocking film 370 may be attached to prevent the inside of the main body 100 from being affected by the external temperature. The temperature blocking layer 370 may be formed of a heat resistant material such as styrofoam. The temperature blocking film 370 may also be attached to the entire surface of the main body 100 or continuously around the outside, or may be partially attached.

In addition, the larvae 310 may be attached to the external access point (D, E) in order to prevent the larvae 310 from falling into the fecal soil discharge portion or the discharge hole (350). The larva barrier 380 may be attached to the upper portion of the helical blade 215 and the side surface of the body portion 100 in a plate shape.

In addition, when the temperature of the portion (A, B, C) mainly dongae 310 is active in the Dongae etc. is 50 ℃ the lower center portion (F) of the main body portion 100 decomposed by the larvae Dongae etc. is the fermentation of the mixture And there is no air circulation, the temperature rises above 60 ℃. In order to prevent such a shape, a temperature sensor (not shown) is installed at the lower center portion F, which is decomposed, and when the temperature reaches a predetermined temperature, for example, 50 degrees or more, the organic waste 320 is used by using the cooling unit 390. ) Can be lowered. In addition, according to another embodiment, the operation may be controlled by the operator operating the cooling unit 390 by looking at the temperature output to the temperature sensor.

Therefore, the organic waste treatment apparatus according to the embodiment of the present invention may further include a temperature controller for checking the temperature of the temperature sensor and operating the cooling unit 390 when the temperature is equal to or greater than a preset reference temperature.

The cooling unit 390 may be a sprinkler using water or a cooling pen using air (wind). The cooling unit 390 may lower the temperature inside the main body 100 until the temperature sensor indicates a predetermined temperature, for example, room temperature (eg, 25 ° C.).

Referring to Figure 3b, the temperature of the lower center portion (F) of the main body portion 100 is formed higher than the temperature of the larvae (A, B, C) and the external access point (D, E). Their temperature is higher than the ambient ambient temperature of the body portion 100. The temperature repeats rising and falling every 6 days, which is the cooling unit 390 every 6 days (5 days, 11 days, 17 days) when the temperature of the center lower portion (F) of the main body part 100 becomes 50 ° C. This is because the internal temperature of the main body part 100 is lowered by operating). Increasing the amount of water in the sprinkler or attaching an air conditioner to the cooling pen can change the temperature rise and fall cycles or widths. In addition, ascending and descending cycles or widths may vary depending on the amount of water or the wind strength.

Therefore, using the heater 360 and the cooling unit 390, it is possible to adjust the temperature (for example, 35 ℃ to 45 ℃) inside the body portion 100 so that the larvae 310 inhabit the Dongae.

In addition, according to another embodiment, the lower portion of the helical blade 215 may be opened entirely so that fecal soil may be directly discharged to the transfer roller 170.

In addition, according to another embodiment, the diameter of the cross section of the helical blade 215 may be increased in the direction in which the fecal soil is pushed. For example, when the helical blade 215 is rotated so that the fecal soil is pushed in a specific direction (for example, in the axial direction of the helical blade 215) inside the main body portion, a large amount of fecal soil may be accumulated in the direction. The diameter of the helical blade 215 (eg, the length of the blade) can be made large so that more fecal soil can be discharged.

4 to 6 is a perspective view of a continuous organic waste treatment apparatus according to a second embodiment of the present invention, a perspective view of the fecal discharge portion and the operation treatment diagram. 4 to 6, the inclined surface 410 formed on the side of the body portion, the upper groove 420 of the body portion, the driven roller gear 440, the rotary operation unit 450, the larva collector 460, the transfer roller ( 470, fecal collection bin 480 and body leg 490 are shown. The differences from the first embodiment described above will be mainly described.

Fecal soil discharge portion includes a plurality of axial wings 515 integrally formed in the axial direction to discharge the fecal soil to the lower portion of the main body 400 during the axial rotation. Meaning integrally formed means that it is formed long in the axial direction, it is natural that the middle may include a partially broken shape. Here, when the middle portion is partially broken, the axial wing portion of the adjacent roller or the adjacent axial wing portion of the same roller may be formed in the form of engagement coupling so as to push the fecal soil with respect to the broken middle region.

When the driving roller is rotated about the shaft by the rotation operation unit 450, the axial wing 515 may push the organic waste inside the main body 400 in the rotational direction to discharge the lower portion of the main body 400.

The driving roller gear 510 formed at one end of the driving roller meshes with the driven roller gear 520 formed at one end of the adjacent driven roller. Also, the plurality of driven roller gears 525 and 445 mesh with each other. An axial wing 515 is formed on both the drive roller and the driven roller. In addition, the axial vanes 515 may be of a length such that they are not physically rubbed with adjacent rollers. That is, the length of the direction perpendicular to the axis of the axial wing 515 may be smaller than the radius of the driven roller gear 525 minus the radius of the driven roller shaft 520. By such an embodiment, the fecal soil can be efficiently discharged down the main body 400. Naturally, the above-described heater, temperature blocking film, temperature control unit, larva blocking film, and cooling unit may be applied to the present embodiment.

Hereinafter, an experimental example of an organic waste treatment apparatus using larvae in Dongae, etc. according to an embodiment of the present invention will be described with reference to specific data.

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

Table 2. Ammonia Generation Concentration

The control group is a combination of food waste and sawdust, the treatment unit 1 is a combination of larvae for food waste, sawdust and dongae, and the processing unit 2 is a combination of larvae and microorganisms for food waste, sawdust and dongae. Here, the introduced microorganism is yeast (yeast), the number of larvae in the injected Dongae, etc. 5000, used food waste is 10kg per day, sawdust serves to help control and fermentation. The size of the container used for the control and treatment is 1,200mm * 600mm * 200mm.

The ammonia concentration of the initial food waste was very high except for the control at 1.4 days in the control, 100.7 ppm in the treatment 1 and 113.9 ppm in the treatment 2. Also, on day 3, ammonia of 203.4 ppm in the control, 424.9 ppm in the treatment 1 and 386.7 ppm in the treatment 2 was generated.

This difference in concentration indicates that the foods in the treatment groups 1 and 2 are being degraded faster than the control, which is due to the larvae to Dongae. When decomposed by larvae in Dongae, etc., ammonia was relatively high in the early stages of treatment due to fermentation and food property degeneration.

In particular, since the larvae can not live in winter, such as larvae can be made to control temperature and humidity in four seasons, and in order to suppress the generation of ammonia, it is necessary to sterilize and chemical reactions of electrical and electronic or to exchange air inside and outside. Generalized systems such as heat exchange and air conditioning systems can be added to reduce and mitigate ammonia generation.

In addition, fecal soil discharged by the embodiment of the present invention is excellent in inefficiency bar can be useful for cultivation of farmland, horticulture, orchards, bar analysis of the components of the conversion product obtained from food waste as shown in Table 3 .

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 fecal soil, which is a food waste decomposition product that larvae decomposed in Dongae-deung, both the content of nitrogen and total nitrogen (T-N) content of Dongae-eung was significantly lower than that of Controls 1 and 2. The nitrogen (N) content and the total nitrogen (TN) content of fecal soil generated at T1 were 30% to 40% and 20%, respectively, compared to the nitrogen (N) content and total nitrogen content (TN) content of fecal soil produced at Control 1 It has been lowered by% to 30%, which means that it has a better composition as a fertilizer.

In addition, larvae and microorganisms were treated at the same time, showing the same result. In addition, when the pH of the food waste was decomposed by the larvae, while the decomposed products of food wastes were acidic in the controls 1 and 2, they were changed to neutral or weakly alkaline, resulting in suitable composting of the decomposed products of the food wastes.

In addition, the analysis of the components of the larvae and pupa in Dongae, etc. produced after the treatment of food waste is shown in Table 4.
