Between the crushing device 20 and the waste treatment device 40, organic wastes are transferred to the crushing device 20 without being exposed to the external environment, so that odors do not leak to the external environment during the transport of the organic waste. Hermetically sealed transfer pipe 45 is installed. The hermetic transfer pipe passage 45 is implemented in the form of a pipe, and a screw 45a that is rotated by the motor 45b is installed therein. Accordingly, the screw 45a is rotated so that the organic waste discharged from the shredding device 20 is transferred to the waste treatment device 40. In this process, the odor contained in the organic waste is not leaked to the external environment.

A pressure feeding pump P is installed between the deodorizing device 60 and the vapor liquefaction tower 50, and the pressure feeding pump P pumps the wastewater produced by the vapor liquefaction tower 50 to be described later to the deodorizing device 60.

Between the waste disposal apparatus 40 and the sorting apparatus 80, the conveyor 85 which transfers the processing result discharged from the waste disposal apparatus 40 to the sorting apparatus 80 is installed. The conveyor 85 may continuously transfer the processing result of several tens of tons discharged from the waste treatment device 40 to the sorting device 80.

The storage tank 10 is a place for temporarily storing the organic waste supplied by the vehicle C, and continuously supplies the organic waste in an amount to be shredded by the shredding device 20. The shredding device 20 cannot shred a large amount of organic waste at a time. Therefore, the shredding device 20 cannot accommodate the organic waste carried by the vehicle C at one time. For this reason, the organic waste transported to the vehicle C is temporarily stored in the storage tank 10.

Shredding device 20 is installed on the lower side of the storage tank 10, to crush the bones and hard foreign matter of the animal contained in the organic waste supplied from the storage tank (10). As shown in FIG. 2, the crusher 20 includes a hopper 21 into which organic waste supplied from the storage tank 10 flows, a hopper mixer 22 installed inside the hopper 21, and a hopper mixer. And a shredder 23 for shredding the organic waste mixed at 22. The organic waste crushed by the crusher 23 of the crusher 20 is introduced into the hermetically sealed transport pipe 45 and then transferred to the waste treatment device 40 through the hermetically sealed transport pipe 45.

The quicklime supply device 30 is for supplying quicklime to the waste treatment device 40, and the amount of quicklime supplied depends on the organic waste to be treated. The amount of quicklime supplied is about 2 to 4 tons based on the weight of 10 tons of organic waste, preferably 3 ton.

Because quicklime reacts with moisture in the air, care must be taken in storage, and large amounts of quicklime are used in the treatment of organic waste. Therefore, a structure for introducing the quicklime into the storage and waste treatment device 40 is required. To this end, the quicklime supply device 30 includes an input pipe 32 for connecting the quicklime storage tank 31 and the quicklime storage tank 31 and the waste disposal device 40 positioned above the waste disposal device 40. And, it includes a supply amount controller 33 for controlling the amount of quicklime supplied from the quicklime storage tank 31 to the input pipe (32).

The quicklime storage tank 31 stores tens of tons of quicklime and continuously supplies the quicklime to the amount controller 33.

The supply controller 33 controls the amount of quicklime supplied to the waste treatment apparatus 40 and may be implemented in various forms. In the present embodiment, the supply amount controller 33 has a structure in which the screw 33a is rotated therein, and the amount of quicklime supplied to the input pipe 32 may be adjusted by the rotation of the screw 33a.

Waste treatment device 40 is a device for treating the organic waste transferred from the shredding device 20 to produce a treatment result for use as a fertilizer or building materials. The waste treatment apparatus 40 is provided with a drum 41 into which the organic waste and the quicklime supplied from the quicklime supply device 30 are fed, and the drum 41 is fed into the closed transport pipe passage 45. It has a mixer 42 for mixing the organic waste and quicklime to produce a treatment result, and an outlet 43 through which the treatment result is discharged. At this time, the mixer 42 is slowly rotated by a motor (not shown).

The drum 41 has an elongated shape having an inner wall having a “U” shape in cross section as shown in FIG. 3, and is made of a non-corrosive metal material such as stainless steel so as not to be corroded by the salt contained in the organic waste. .

The mixer 42 mixes the organic waste and quicklime in the drum 41 to prevent precipitation, induces a reaction between the organic waste and the quicklime, crushes the resultant treatment by mixing and reacting the organic waste and the quicklime Make sure that no lumps are formed and that the result of the treatment does not adhere to the inner wall.

Quicklime hardens quickly by reacting with organic waste containing moisture, and to prevent this, the mixer 42 should be rotated at a high speed of 20 to 40 RPM, preferably 30 RPM. In order to make this possible, the mixer 42 includes a shaft portion 42a rotated by a motor (not shown), a plurality of support blades 42b installed on the shaft portion 42a, and a support. The blade 42b is composed of a ribbon blade 42c in which a strip-shaped plate is connected in a ribbon shape, and the shaft portion 42a is disposed along the longitudinal direction of the drum 41. The mixer 42 has a ribbon screw-type consisting of the support blade 42b and the ribbon blade 42c, thereby minimizing the frictional force generated during the mixing of the organic waste and quicklime, and rotating at a high speed of 20 to 40 RPM per minute. This is possible.

The quicklime reacts with organic wastes containing moisture and becomes a treatment result that can be recycled as fertilizer or building materials, and absorbs the salts contained in the organic wastes. In addition, quicklime reacts with organic waste to generate high heat of about 200 ℃ or higher, and high heat enables rapid drying by evaporating moisture that does not react with quicklime, and dissolves animal hairs.

On the other hand, the degree of drying the treatment result is changed depending on the time to be processed in the waste treatment apparatus 40.

For example, 10 ton of organic waste is mixed with 3 tons of quicklime and treated for 3 to 4 hours to produce 20 to 30% water. This resulted in the rapid improvement of acid soils and alkalinization. In addition, it is used as a calcareous fertilizer to supply calcium to fabrics.

And when the treatment time is 5 hours or more, the moisture content of the treatment result drops to around 5%, and this treatment result can be used as a building material such as brick.

As such, the drum 41 is formed in an elongated form having an inner wall of the “U” shape, and the mixer 42 is a ribbon screw type in which the mixer 42 is disposed in the longitudinal direction, whereby the quicklime and the organic waste can be effectively mixed and reacted. As a result, a large amount of organic waste can be processed quickly.

The vapor liquefaction tower 50 liquefies the steam generated by the waste treatment apparatus 40. The vapor liquefaction tower 50, the collection body 52 having a tower body 51 installed on the upper side of the drum 41, the inner diameter of the narrower to the upper side connected to the inner peripheral surface of the tower body 51, and the collection A cap 53 which is spaced apart from the upper portion of the pipe 52 and extends outward of the collection pipe 52, and a cooling unit 54 for cooling the tower body 51 to promote liquefaction of steam. Include.

In this case, the cooling unit 54 may be implemented by installing a plurality of heat dissipation fins on the outer circumferential surface of the tower body 51. Alternatively, the cooling unit 54 may be implemented by forming a cooling flow path through which cooling water flows on the outer circumferential surface of the tower body 51, and in this case, tap water supplied by being directly connected to the water pipe may be used as the cooling water. In addition, at the lower side of the tower body 51, a sieve 55 for filtering the processing result that can be introduced into the tower body 51 by the mixer 42 may be installed.

Due to the structure of the vapor liquefaction tower 50, the vapor evaporated from the drum 41 swings downward after hitting the cap 53, in the process steam is cooled to the tower body 51 is cooled by the heat of the outside air Is liquefied to become wastewater.

Deodorizer 60 is for deodorizing the odor component contained in the waste water discharged from the vapor liquefaction tower 50 to be treated water. Deodorizing device 60 is a deodorizing filter 61 is built in the inside, the deodorizing filter 61 is preferably made of carbon material.

The treated water collection tank 70 is a place for storing the treated water produced by the deodorizer 60.

Wastewater is treated water by removing a significant amount of odor components and salt by the deodorizer 60, but if the salinity of the organic waste is considerably high, the salinity of the treated water may be higher than the reference value. This high salinity treatment water is likely to contaminate the soil and water supply source, in order to prevent this is to employ a treatment water collection tank 70 for temporarily storing the treated water treated by the deodorizer 60.

The treated water stored in the treated water storage tank 70 measures salinity to be drained when the salinity is lower than the reference value. If the salinity of treated water is above the reference value. A separate treatment method is to reduce the salinity to drain.

The sorting device 80 is for sorting the processed result processed by the waste treatment device 40 according to the size. The treatment result treated in the waste treatment device 40 has a lump form of various sizes in response to calcination. These various sizes of the processing results are sorted using the sorting device 80 so that the processing results of the small size can be immediately packaged and commercialized, and the processing results of the large size are made small through a separate shredding process.

The processing result sorted by the sorting device 80 is transported to the packaging machine 90 and packaged and shipped.

Next, the operation of the organic waste treatment system of the present invention will be described.
