Description

[0001] The present invention relates to a food waste treatment apparatus using a larva,

More particularly, the present invention relates to a device for treating food wastes in an environmentally friendly manner using larvae such as Donga, etc. More specifically, the effect of treating food wastes is maximized by increasing the activity of larvae on the wing, To a food garbage disposal apparatus that is configured to be separated from the food garbage disposal apparatus.

Generally, various types of wastes are generated in the wastes generated by human life. These various wastes are treated with waste disposal technology and pollution prevention technologies and policies to reduce environmental pollution. However, the waste disposal technology and pollution prevention technology can not solve this problem or the waste can not be accepted. It is becoming reality. Among such wastes, food wastes containing organic matter and manure wastes are treated in various ways.

The double food garbage has been recycled by some feeds and composting, and most of the rest has been disposed of by landfilling and incineration. However, since 2005, it is prohibited to land directly in the land, and food waste is now recycled and incinerated by feed conversion and composting have.

However, in the case of direct feeding of food wastes, various diseases are caused. In the case of composting, contamination of the soil due to salt and leachate is a problem. In case of incineration, most incinerators are incinerated together with other wastes, However, in the case of landfill, it is necessary to secure the landfill site or the land by the leachate and the landfill by landfill. Secondary environmental pollution resulting from groundwater contamination is becoming a problem.

In addition, in case of livestock manure, it became a major resource as a nutrient source or soil improvement agent in the rural area instead of chemical fertilizer. However, as livestock production farms are increased and rapidly changed according to changes in agricultural structure, the circulation system of livestock manure is not maintained, There was a problem.

Methods for treating organic wastes using soot and the like have been developed as a method for solving the above problems. As a representative environmental purifying insect, this kind of homosexuality only feeds on the larval stage and does not feed on the adult stage. They travel to the forests to get away from people and live in areas where organic wastes such as housing, living garbage and food waste are covered.

Therefore, in Dongae, when the larvae eat, they eat food waste and liver fatigue by eating a strong appetite, and when they become adult, unlike Paris, they do not enter the house or harm people.

The duration of the larvae to the adults is 37 ~ 41 days. The larvae decomposing the organic waste is 14 days. When the food waste is supplied to 5,000 larvae of 5 larvae at 10 ㎏, the food waste is reduced by 58% The weight changes to 30% less good quality compost.

As described above, a continuous organic wastes treatment apparatus using a larval larva (Korean Patent Registration No. 10-1003088), which is configured to treat food wastes by using larvae, has been proposed. When the conventional organic waste disposal apparatus is used, it is advantageous that the food waste can be eco-friendly because the larvae eat and dispose of the food waste.

However, since the conventional organic waste disposal apparatus is manufactured only by supplying the food waste to the larvae in the east, it is difficult to improve the activity of the larvae in Dongae and the like, and when the larvae are transformed into the pupa, Therefore, there is a problem that it is difficult to breed adults in Dongae and the like.

The double-throw screw 200, which is positioned below the loading door 110, is arranged so that two or more pulverizing screws are in parallel contact with each other and are inserted from the loading door 110, And performs a function of finely crushing the food waste. At this time, the double screw 200 can be replaced with any structure as long as it can crush the food waste finely. In addition, the double screw 200 can function not only to finely grind food waste, but also to squeeze water contained in food waste. When the double screw 200 performs a function of squeezing the moisture contained in the food waste, the water squeezed by the double screw 200 is guided to the housing 100 through a separate guide plate (not shown) As shown in FIG. The structure in which the double screw 200 squeezes and collects the moisture contained in the food waste is applied substantially the same as the conventional food waste disposal apparatus, and therefore, a detailed description thereof will be omitted.

The reservoir 300 located below the double screw 200 is a component for storing the food waste grinded by the double screw 200 and is formed in a concave container shape. The larvae hatchery 500 located at the side of the storage tank 300 is a space for raising the larvae 20 to a large number of homosexuals and is provided with a large amount of sawdust 10 to help grow the larvae 20, Is filled.

The food waste stored in the storage tank 300 is transferred to the larvae hatchery 500 where the larvae 20 are kept in the hometown and is used as a food for the hunting etc. The food waste in the storage tank 300 is automatically stored in the larva 500, a transfer screw 400 is provided between the storage tank 300 and the larval hatchery 500. [

The ramp 520 is a component for separating the larvae 20 from the food waste by using the habit of moving the larvae 20 to a dry place before the larvae 20 transform into a pupa, As shown in Fig. At this time, the upper end of the ramp 520 is provided with a reservoir 600 through which the larvae 20 can be collected in a large amount.

Meanwhile, the food garbage disposal apparatus using larvae according to the present invention includes a heating unit 700 and an air blower 800 so as to provide temperature and humidity suitable for the growth of the larvae 20, The unit 700 can be applied as an electric heater, a combustion heater, a solar heater, a geothermal heater, or the like, as long as heat can be applied inside the larva hatchery 500.

Hereinafter, the process of treating food waste using a food waste disposal apparatus using larvae according to the present invention will be described in detail.

In order to treat food waste using a food waste treatment apparatus using larvae according to the present invention, first, the inlet door 110 is opened and food waste is introduced.

The food garbage introduced through the inlet door 110 is finely crushed by the double screw 200 and collected into the storage tank 300. At this time, in order to effectively decompose the food waste, the food waste must maintain a predetermined temperature. Generally, the food waste put through the inlet door 110 has a low temperature. Therefore, the food waste collected in the storage tank 300 through the inlet door 110 is stored in the storage tank 300 for about one day so as to be raised to a temperature suitable for decomposition.

When the food waste in the storage tank 300 reaches a temperature suitable for decomposition, the operator operates the transfer screw 400 to transfer the food waste in the storage tank 300 to the larval hatchery 500. Of course, the conveying screw 400 can be configured to automatically operate when the food waste in the storage tank 300 is raised to a temperature suitable for decomposition. For example, when the temperature sensor detects temperature of the inner space of the storage tank 300 and the temperature measured by the temperature sensor reaches a predetermined temperature or more, Lt; RTI ID = 0.0 > a < / RTI > When the feed screw 400 is configured to operate automatically, it is possible to supply food waste having a temperature suitable for decomposition to the larval hatchery 500 even if the operator does not check the temperature of the food waste in the storage tank 300 have.

When the food waste is supplied to the larval hatchery 500, the larvae 20 feed on the food waste in the larvae hatchery 500, and the food waste stored in the storage tank 300 is maintained at a certain temperature But may not rise to a temperature optimized for the activity of the larvae 20 on the same subject. Therefore, the food garbage disposal apparatus using the larva according to the present invention may further include a heating unit 700 for maintaining the temperature of the larva hatchery 500 at a predetermined range. In addition, if the inside of the housing 100 is blocked from the outside, moisture may be excessively increased due to moisture evaporated from the food waste, which may be an obstacle to the growth of the larvae 20, Therefore, according to the present invention, the food garbage disposing apparatus using larvae of the present invention is capable of ventilating the air of the nerve of the housing 100 so that the humidity inside the housing 100 can be maintained at a suitable humidity for the growth of the larvae 20, (Not shown).

On the other hand, the food waste supplied to the larvae hatchery 500 is heated by the heating unit 700 so as to reach the optimum activity temperature of the larvae 20, The food waste in the vicinity of the bottom surface of the larva hatchery 500 may not be heated by the heating unit 700. [

Therefore, the apparatus for treating garbage using the larva according to the present invention comprises an agitator 510 for agitating the garbage within the larva hatchery 500. When the agitator 510 is provided in the larva hatchery 500 as described above, the food waste in the larva hatchery 500 is uniformly mixed by the heating unit 700 while being evenly heated. As a result, ), Thereby maximizing the decomposition effect of the food waste. At this time, when the stirrer 510 is continuously operated and the food waste is mixed for 24 hours, the larvae 20 may interfere with eating food waste. Therefore, the stirrer 510 preferably operates intermittently in accordance with a predetermined period.

According to the research and statistics of the Rural Development Administration, 10kg of larva (20) consumes 10kg of food waste per day, so that food waste can be treated quickly and the amount of leachate and odor generated can be reduced.

In addition, the moisture is evaporated while the larvae 20 feed on the food waste, and the salinity is reduced from about 3% to about 1%, so that the sawdust 10 and feces can be utilized as compost . There is also statistical data showing that the wasted soil of Dongae is better than that of the earthworm. In other words, it can be expected that the waxy soil of Dongae and so on will have an effect of promoting the growth of crops such as wheat, soybean, tomato, and lettuce and improving the productivity, thereby increasing the income of farmers.

The larva 20 in the larva hatchery 500 is transformed into a pupa after about 10 to 15 days have elapsed, and the larva 20 has a habit of moving to a dry place when it is transformed into a pupa . Therefore, the larvae 20 in the larvae hatchery 500 ascend the slope 520 so as to be as far as possible from the food waste in the larva hatchery 500.

At this time, the reservoir 600 is connected to the upper end of the ramp 520, and the larvae 20 are collected in the reservoir 600 on the ascending aisle 520. As described above, when the food garbage disposing apparatus using the larva according to the present invention is used, the larvae 20 are transformed into the pupa in the reservoir 600, so that the operator removes the reservoir 600, It is easy to breed. In addition, when adults can be reared in Dongae and the like, a large amount of larvae (20) can be obtained in Dongae and the like, and an adult fertilizer can be utilized as an adult fertilizer.

At this time, if the reservoir 600 is filled with the larva 20, the operation of confirming the amount of the larvae 20 in the reservoir 600 is required. There are a lot of hassles. Therefore, the food garbage disposal apparatus using larva according to the present invention may further include a weight sensor 610 for outputting an alarm or a signal when the weight of the reservoir 600 exceeds a preset reference value have.

If the weight sensor 610 is additionally provided in the reservoir 600 as described above, the operator can know the amount of the larvae 20 in the reservoir 600 even if the reservoir 600 is not visually confirmed, The food garbage disposing device using larvae according to the present invention can be easily utilized.

2 is a sectional view showing the structure of the storage tank 300 included in the present invention.

Generally, the food garbage contains a large amount of water. Therefore, when a large amount of food waste is filled in the storage tank 300, a large amount of moisture can be collected on the bottom surface of the storage tank 300.

Even if the transfer screw 400 transfers the food waste in the storage tank 300 to the larva hatchery 500 side, the moisture contained in the food waste is collected on the bottom of the storage tank 300, A large amount of leachate may be generated in the storage tank 300 when the food garbage disposal apparatus using the larva is operated.

The water reservoir 320 is formed on the bottom surface of the reservoir 300. The water reservoir 320 collects and discharges the water flowing out through the drain hole 310 and transfers the moisture to one side. And a pump 330 for discharging the moisture collected by the housing 100 to the outside of the housing 100.

When the water receiver 320 and the pump 330 are additionally provided as described above, the water in the storage tank 300 falls down through the drain hole 310 and is discharged to the outside by the pump 330, The leachate is not generated in the leachate, and there is no fear of generating odor.

3 is a cross-sectional view showing the structure of a larva hatchery contained in the present invention.

After the food waste transferred to the larval hatchery 500 is completely processed, the feces and the sawdust 10, in which the larvae 20 have been dispensed, are to be pushed out from the larval hatchery 500 and used as compost. And the sawdust 10 are labor-intensive and require a long time to be manually performed by the operator.

A discharge port 530 through which the feces of the larva 20 is discharged can be formed on the bottom surface of the larva custody 500 and the discharge door 540 for opening and closing the discharge port 530, A sawdust 10 drawn out through the outlet 530 and a discharge pipe 550 into which the feces is introduced to one side of the inner space and a discharge pipe 550 rotatably mounted inside the discharge pipe 550, A saw blade 10 on one side and a discharge screw 560 for discharging the feces to the outside of the housing 100 may be additionally provided.

When the discharge pipe 550 and the discharge screw 560 are provided below the discharge port 530 of the larva hatchery 500 as described above, the operator can open the discharge door 540 only by opening the discharge door 540, 10 can be discharged to the outside of the housing 100, there is an advantage that workability is remarkably improved.

At this time, after discharging both the feces and the sawdust 10 in the larva hatchery 500, the larva 20 is filled in the new sawdust 10 and the like in the larva hatchery 500, and the other food waste is processed .

Fig. 4 is a cross-sectional view showing the configuration of the second embodiment of the larva habitation area included in the present invention. Fig.

Even if most of the larvae 20 on the larva custody site 500 climb up the ramp 520 and are picked up in the reservoir 300, the larvae 20 are not able to catch up with the sawdust 10, It may be necessary to remove the feces of the larva 20 from the sawdust 10 and the like and then discharge the larva 20 from the housing 100 to the outside of the housing 100 for use. 3, when the feces of the larva 20 is discharged to the same location as the sawdust 10 in the larva hatchery 500, the larva 20 is injured by the discharge screw 560, There is a problem that the wearer can wear the clothes.

Therefore, the food garbage disposal apparatus according to the present invention is characterized in that the side of the larva hatchery 500 is provided with the sawdust (20) so as to discharge feces of the larvae 20 to the sawdust 10 and the like without injury to the larvae 20, The sawdust 10 and the feces in the larva hatchery 500 are discharged to the discharge port 530 by the rotational force of the stirrer 510. The discharge port 530, As shown in FIG.

At this time, a sidewall of the larva hatchery 500 is provided with a discharge door 540 for opening and closing the discharge port 530.
