Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a food waste, a livestock waste, and a sewage sludge treatment apparatus.

The present invention relates to a food waste, a livestock manure and a sewage sludge disposal apparatus, and more particularly to a disposal apparatus for disposing food garbage, livestock manure and sewage sludge treated by aerobic microorganisms, mixed bacteria and food waste, livestock manure and sewage sludge, ≪ / RTI >

In general, food waste, livestock manure and sewage sludge, which are organic waste types, are a major cause of contamination of soil, water quality and air if not treated separately. In addition, food waste, livestock manure, and sewage sludge are facing the problem of manure disposal in livestock due to prohibition of marine dumping.

Recently, devices for treating livestock manure have been developed and devices for fertilizing processed livestock manure have been developed and popularized.

Conventional livestock manure treatment system transports livestock manure, collects livestock manure into sludge and liquor by solid-liquid separator. The sludge is mixed with other by-products and used as compost after fermentation and aging, and the liquor is fermented and used as liquefied fertilizer.

The second agitating screw 220 can agitate food waste, livestock manure, and sewage sludge by the stirring action of the first agitating screw 110 and the second agitating screw 220. The second agitating screw 220 can rotate with the first agitating screw 110 formed in a direction opposite to that of the first agitating screw 110. The second agitating screw 220 can be rotated in one rotation direction and conveyed in the twisting angle direction. Here, the second stirring screw 220 prevents the conveyed object, which is reversely rotated in the twisting angle direction of the first stirring screw 110, from being entangled with the conveyed object while reversing the conveyed object inside the treatment vessel 10 once again .

The first support part 150 is formed at both ends of the rotary shaft 40 so that the rotary shaft 40 and the first stirring screw 110 can be spaced apart from each other by a predetermined distance. The first support part 150 may be formed so as to extend from both ends of the treatment tank 10 so as not to come into contact with connection parts formed at both ends of the rotary shaft 40.

The second support part 250 is formed at both ends of the rotary shaft 40 so that the rotary shaft 40 and the second stirring screw 220 can be separated from each other at regular intervals. The second support part 250 is different from the first support part 150 only in shape and function, so that a duplicate description will be omitted.

The third support part 160 may be formed between both ends of the rotary shaft 40 to separate the rotary shaft 40 and the first stirring screw 110 at a predetermined interval. The third support part 160 may be formed at every 180 ° or 90 ° rotation point from the connection part between the first stirring screw 110 and the first support part 150. The third support portion 160 may include a first support bar 160a and a second support bar 160b formed between the inner surface 130a of the first stirring screw 110 and the rotary shaft 40. [

The fourth support portion 260 may be formed between both ends of the rotary shaft 40 to separate the rotary shaft 40 and the second stirring screw 220 at a predetermined interval. The fourth support portion 260 may be formed at every 90 ° or 180 ° rotation point from the connection portion between the second stirring screw 220 and the second support portion 150. The fourth support portion 260 may include a third support bar 260a and a fourth support bar 260b formed between the inner surface 130b of the second stirring screw 220 and the rotary shaft 40. [

Since the fourth support portion 260 is different in position and function from the third support portion 160, duplicated description is omitted.

4 is a perspective view illustrating a food waste, livestock manure, and sewage sludge treatment apparatus according to a second embodiment of the present invention.

Fig. 4 includes the same components as those of Figs. 1 and 3 except for the shape of the second treatment tank 11. Therefore, although the second processing tank 11 is the same internal component, different reference numerals are given to the second processing tank 11, and redundant description of the same components is omitted.

Referring to FIG. 4, the second treatment tank 11 may include a first agitation unit 100 and a second agitation unit 200.

The first stirring part 100 and the second stirring part 200 may include a rotating shaft 40, a driving motor 50, a first supporting part 150, a second supporting part 250, 3 supporting portion 160 and a fourth supporting portion 260 are provided.

The first agitator 100 and the second agitator 200 may be disposed in parallel with each other in the second treatment tank 11.

In the U-shaped second treatment tank 11, food waste, livestock manure, and sewage sludge may remain in the overlapped space between the first agitating unit 100 and the second agitating unit 200, W-shaped.

The stirring action of the screw can be activated in the overlapping space of the first stirring part 100 and the second stirring part 200 in the second treatment tank 11.

The second treatment tank 11 can increase the lengths of both ends of the second treatment tank 11 and the lengths of the first agitation unit 100 and the second agitation unit 200 so that a large amount of food waste, Can be accommodated.

In the food waste, livestock manure and sewage sludge disposal apparatus according to the embodiment of the present invention, food waste, livestock manure and sewage sludge in the treatment tank are decomposed and lost by aerobic microorganisms and complex bacteria. Therefore, Reuse garbage, livestock manure, sewage sludge and sawdust. After the agitation process and the livestock manure application process have been carried out several times, the decomposed residues in the treatment tank are discharged. At this time, a part of the discharged residues is left in the treatment tank so that the aerobic microorganisms and the complex bacteria are not reintroduced when the livestock manure is put in the future.

Food waste, livestock manure and sewage sludge disposal system can reduce and extinguish livestock manure by using aerobic microorganism and complex bacteria in the treatment tank, so it is not necessary to transport food waste, livestock manure and sewage sludge, And infectious factors can be eliminated.

The apparatus for treating garbage, livestock manure and sewage sludge according to the embodiment of the present invention comprises a plurality of screws extending in a direction opposite to the direction of rotation of the first stirring screw and the rotation direction of the second stirring screw So that the conveyed matter to be conveyed is pushed to the vicinity of the center of the treatment tank and can activate pressure and stirring with each other.

In addition, the food waste, livestock manure, and sewage sludge treatment apparatus according to the embodiments of the present invention can advantageously utilize the aerobic microorganisms and complex bacteria remaining in food waste, livestock manure, and sewage sludge.
