As the livestock industry is shifted to industrial scale, challenges are being raised to prevent the pollution and enormous amounts of waste produced in farm houses. Construction of livestock farming is accelerating overall, and a US researcher has published that animal and livestock waste destroys the environment more than household waste. In the United States, agricultural livestock produce about 150 million tonnes per year, which is four times the total domestic waste.

There is no question that the livestock waste must be rationally used for cultivation or crop cultivation, but there is no wide enough place around large livestock houses, and unprocessed people cannot be used as fertilizers. The accumulation of a large amount of people who do not have a large amount may actually present a risk of air pollution or pathogenic bacteria or parasites caused by harmful substances. In this context, R & D is underway to fertilize flour in a short period of time.

Accordingly, an object of the present invention is to devise a solution to the above problems, flies using livestock manure has no odor in a short period of time, the moisture content is good, making the plant a stable compost easy to intake nutrients Livestock manure treatment apparatus using larvae.

At this time, by installing a fertilizer drying conveyor 36 at the end of the fertilizer transfer screw 34, the fertilizer discharged from the silo 33 is dried using a ventilator and other dryers to contain moisture suitable for packaging and storage. Let's do it.

At the end of the fertilizer drying conveyor 36, a well-known pallet machine (GR 101 to GR 501 of Okto Development ENG Co., Ltd.), which is a fertilizer packaging means, is installed so that the dried fertilizer can be pelletized and automatically weighed and packaged.

Referring to the operation and effects of the livestock manure treatment device using the fly larva according to the present invention configured as described above are as follows.

Nutrient-rich livestock meal (糞) is inhabited with a variety of insects, these insects can be seen that promote the composting of livestock meal, some of which are able to breed.

Of these, the musca's domestic lean species, the housefly, is a species that lives widely in human life, and one female lays more than 70 to 100 eggs per egg laying. During the life span (33-62 days), one female spawns 11-20 times and the spawning property of housefly is extremely high even under natural conditions.

The number of housefly adults is very high in places where the barn is not in good condition. For example, 200 to 500 flies can be counted for each cow in the barn. This large amount of flies worsens the sanitary environment and reduces livestock productivity, but at the same time plays a role in composting animal waste.

The use of flies for the purpose of recycling livestock waste is a natural and ecological phenomenon that is considered to be a very practical and rational way.

When constructing livestock meal treatment lines by housefly larvae, safety hygiene regulations are observed and their concentrations are below the allowable limits so that toxic gases do not affect the working environment.

First, the livestock meal is collected from the barn using the vehicle C or the like. The collected livestock manure is mixed through a raw material mixing screw 11 to control moisture and other culture conditions, and then the raw material which is properly mixed livestock manure is intermittently sent out through the raw material conveying screw 12. Collected livestock manure is approximately 90% moisture, re-introduced after composting (50-55% moisture) of about 10%, the water content of about 80% becomes a suitable raw material for the growth of larvae.

The raw material thus sent is transferred to the main conveyor through the raw material conveying conveyor 13. The raw material conveying conveyor 13 is installed to be inclined upward and transfers the transferred raw material to the upper part of the first main conveyor part 21a which is the first main conveyor part.

The raw material transferred to the first main conveyor unit 21a is collected in the raw material sorting hopper 22, and the raw material collected in the raw material sorting hopper 22 is spread out on the upper surface of the first main conveyor unit 21a and raised. Then, through the raw material sorter 24 installed on one front side of the raw material sorting hopper 22 is spread evenly to a predetermined thickness, about 5 ~ 7 cm thickness on the front surface of the first main conveyor portion (21a).

Using a paral injector (not shown in the drawing) that automatically sprinkles the flies on the raw material spread to a certain thickness, a predetermined amount per unit raw material, 0.3 g per 1 kg of the eggs are added. The fly uses a housefly, a Musca domestic lean species. Depending on the type of livestock manure to be collected, several suitable types of fly eggs may be mixed and added.

The raw material into which the fly eggs have been fed is transported through the first main conveyor unit 21a, and while the larvae wake up from the eggs and feed on the raw materials to make fertilizer (compost). For convenience, larvae and livestock manure containing larvae are called intermediate raw materials.

The first main conveyor 21a is composed of a plurality of floor conveyors, and each floor conveyor is alternately shorter at one end than the lower floor conveyor so as to transfer intermediate materials to the next lower conveyor. That is, the intermediate raw material conveyed in one direction along one short top conveyor falls to the lower lower conveyor on the other side by its own weight at the end, and the intermediate raw material dropped to the lower level conveyor is transferred along the conveyor in the other direction again and zigzag. Is moved to the bottom. In FIG. 3, the right end of the uppermost conveyor 26a of the 1st main conveyor part 21a is provided short, and the lower end conveyor 26b is provided with the right right long, and below the right short is short and below it. Shows a structure in which the left end is short and in this way, one end of the upper conveyor and the other end of the lower conveyor are alternately short.

In this way, the livestock wastes matured in the first main conveyor portion 21a reach the bottom of the first main conveyor portion 21a and are transferred to the first intermediate transfer conveyor 23a, and then to the first intermediate transfer conveyor 23a. The transferred intermediate raw material is transferred to the first slant conveyor 25a inclined upward through the second intermediate transfer conveyor 23b. The intermediate raw material conveyed to the first slat conveyor 25a is moved upward along the inclined conveyor and transferred to the upper portion of the second main conveyor 21b having the same structure as the first main conveyor 21a.

The intermediate raw material transferred to the second main conveyor portion 21b comes down while being transferred zigzag along each stage like the first main conveyor portion 21a, and the larvae continue to ingest the raw material by ingesting the manure while descending. It grows while.

The intermediate raw material transferred to the lowest end of the second main conveyor portion 21b is moved back to the second slant conveyor 25b inclined upward through the third intermediate transfer conveyor 23c, and the second slat conveyor 25b. The raw material transferred to) is moved upward by riding the second slat conveyor 25b and is transferred to the upper end of the third main conveyor 21c having the same structure as the first main conveyor 21a.

The intermediate raw material transferred to the third main conveyor unit 21c is zigzag down along the stages as in the second main conveyor unit 21b, while the larvae continue to ingest the raw material and grow to pupa while descending. You grow up to The mature larvae escape the conveyor to become pupa.

The raw materials transferred to the bottom of the third main conveyor 21c are all fertilized and discharged through the fertilizer collection conveyor. At this time, the raw material is ingested by the fly larvae while passing through the first, second and third main conveyors, and becomes an odorless fertilizer with no smell.

The residence time of intermediate materials in the first to third main conveyors depends on the temperature and other environmental conditions, but usually takes 4 to 7 days.

The fertilizer transported through the fertilizer collection conveyor 31 is transferred to the silo 33 through the fertilizer transport conveyor 32 and stored.

The fertilizer transport conveyor 32 is installed to be inclined upwardly to move up and move up the fertilizer, and the up-shifted fertilizer is introduced and stored through the top inlet of the silo 33.

The fertilizer thus stored is intermittently discharged from the silo 33 through the fertilizer feed screw 34 connected to the lower outlet of the silo 33. At this time, the end of the fertilizer feed screw 34 is arranged by the known pellet manufacturing machine 35, the fertilizer transported through the fertilizer feed screw is discharged at a high pressure to produce a pellet form to standardize the fertilizer, and also exists in the fertilizer Can kill the larvae.

The fertilizer discharged from the pellet maker 35 is dried by a ventilator and other dryers to contain moisture suitable for packaging and long term storage via the fertilizer drying conveyor 36.

The fertilizer thus dried is automatically weighed and packaged through a packing machine (not shown in the drawing) which is a raw material packaging means installed at the end of the fertilizer drying conveyor 36.

On the other hand, the larvae grown for a certain period of time in the first, second, third main conveyors (21a, 21b, 21c) to escape from the raw material to become a pupa, the escape larvae are the third main conveyor (21c) Geared to both sides of the falling to the larvae conveyor 41 installed in the lower end, the larvae dropped to the larvae collection conveyor 41 is transferred to a separate place through the larva transfer conveyor 42 is stored.

After a certain period of growth, most of the larvae escape from the raw material due to the ecological characteristics crawling out to become pupa, but some remain in the raw material. If there are a large number of remaining larvae, the larvae are artificially separated from the fertilizer.

The isolated larvae are stored together with the escaped larvae, and are treated separately to be used as high protein feeds.

Cattle disposal by housefly larvae can realize re-recycling of nearly complete meals, protecting the environment from contamination by livestock waste and further preventing flies from occurring in waste deposits from livestock and There is an effect that can prevent the spread of.
