Description

{Stirrer terminating by fermentation of organic waste}

The present invention relates to a fermentation elimination agitator for organic waste, and more particularly to a fermentation and dissolution agitator for organic waste which comprises a feedstock process transfer screw which rotates in the opposite direction and which is integrally formed with each other, and a transfer stir plate which is obliquely twisted on the inner circumferential surface of the raw material disposal bottle The present invention relates to a fermentation elimination agitator for organic waste which efficiently transports organic wastes such as food wastes introduced through a charging section of a raw material disposal bin and ferments the wastes while stirring.

Organic waste, such as food waste, is recycled as feed for livestock because it is badly odorous when it becomes corrupted. However, there is a limit to the amount of food to be recycled. Recently, many. However, the organic waste such as food waste is fermented and extinguished in such a way that it is effective only in a small amount, but the efficiency is remarkably low at a large capacity.

In order to solve this problem, in order to dispose and treat a large amount of organic waste by fermentation, it is necessary to have a large-sized stirring apparatus such as a very large passing giant screw capable of accommodating such a large amount of organic waste, It is disadvantageous that the fermentation is carried out by transferring the organic waste at a time into a very large barrel and then transferring it to the giant screw so that it can not be properly fermented due to too much organic waste. That is, even if the organic waste is transported to a large conveying screw, there is a problem that the organic waste is not sufficiently dispersed in the organic waste, and thus the organic waste is not sufficiently fermented by the microorganism.

In addition, although the conventional methods of the above-mentioned organic waste are large-scale agitation facilities, the conventional methods are in the form of a rotary blade and a screw. However, if the excessive axial force and the range of the material treatment vessel of a certain size using the reducer are out of range, There is a problem that the agitation facility is not operated properly.

In order to solve such a problem, in an eco-friendly waste fermentation drying apparatus (No. 10-1507303) as in Patent Document 2 of the prior art document, a stirring blade 33 is installed in a stirring drum 30 And the efficiency of fermentation is improved by appropriately stirring organic wastes in the stirring drum 30 rotated by the stirring blade 33. However, as described above, since the stirring blade 33 only agitates the organic waste in the rotating stirring drum 30, the efficiency of fermentation is not so high.

The twisting direction of each of the conveying agitating plates 7 is attached in a direction opposite to the rotating direction of the raw material treating cylinder 1. In the drawing of the present invention, Since the barrel 1 is rotated in the leftward direction (counterclockwise direction), each of the conveying agitating plates 7 is twisted obliquely in the rightward direction (clockwise direction). 3, seven transfer rollers 7 are attached at intervals of about 51 degrees along the inner circumferential surface of the raw material container 1 as shown in FIG. But it may be attached to less or more depending on the size and length of the raw material treating cylinder 1. [

The raw material treatment tank 1 is rotated by a rotating means, that is, between a raw material treatment tank 1 and a rotary motor 8a for raw material treatment universal rotation by a pulley and a rotating belt. In the raw material treatment tank 1, The motor pulley 9 mounted on the motor shaft of the raw material processing rotary motor 8a disposed on the discharge portion 20 side of the raw material processing cylinder 1 and the tubular pulley 10a provided on the center portion of the rear surface of the raw material processing cylinder 1, 16). Although not shown in the figure, the raw material treatment tank 1 may be rotated by engaging and connecting gears provided in the center of the rear surface of the raw material treatment tank 1 and gears mounted on the motor shaft of the raw material treatment station rotary motor 8a .

The feed screw 2 is inserted through the central portion of the raw material processing tube 1 and inserted into the tubular input portion 3 and the discharge portion 20 at the front and rear sides, The shape is processed. The conveying screw 2 is rotated by the rotating means, that is, between the conveying screw 2 and the rotating screw 8b for the conveying screw, by means of the pulley and the rotating belt. The feeding of the raw material treating cylinder 1 A motor pulley 9 mounted on a motor shaft of a rotary screw motor 8b for a feed screw disposed on the side of the feed section 3 and a feed pulley 9 mounted on the end of a feed screw on one side of the feed screw 3, 10b are connected by a rotary belt 16 and rotated. Although not shown, the conveying screw 2 is rotated by engaging and engaging a gear mounted on the end of the one conveying shaft of the conveying screw 2 and a gear mounted on the motor shaft of the conveying screw rotating motor 8b It is possible.

A feed vane 21 is attached to an outer circumferential surface between both screw forms of the feed screw 2 at a predetermined interval and the feed vane 21 is arranged in the longitudinal direction between both screw forms of the feed screw 2 Are installed at regular intervals. The feed vane 21 is formed such that the vane plate 21b is obliquely attached to the side of the end of the rod-like feed rod 21a toward the discharge portion 20 of the raw material feed cylinder 1. 3, four transfer wings 21 are attached at an interval of 90 degrees along the outer circumferential surface of the transfer screw 2 as shown in FIG. 3, and ten transfer wings 21 are arranged at regular intervals along the longitudinal direction of the transfer screw 2 Respectively. The transfer wing 21 may also be attached less or more depending on the size and length of the transfer screw 2.

The feeding part 3 and the discharging part 20 are connected to the raw material treatment barrel 1 in a state including the conveying screw 2 inside the raw material barrel 1 in front of and behind the raw material barrel 1, The charging unit 3 and the discharging unit 20 are fixed and connected without rotating so as to rotate only the raw material treatment tank 1.

The air introducing means 4 includes an air inlet 11 passing through the center of the conveying screw 2 and a plurality of air holes 11 formed through the outer circumferential surface of the conveying screw 2 so as to communicate with the air inlet 11. [ A blower 13 is disposed in front of an air inlet 11 connected by a rotary joint so that the air is blown by the blower 13 into the air inlet 11 and the air And is supplied into the raw material treatment tank 1 through the discharge hole 12. At this time, since the air discharge hole 12 has a narrow inside diameter and a large outside diameter, the organic waste and debris can smoothly discharge the air even if the air discharge hole 12 is blocked It does not clog well. That is, since the organic waste is only half circulated in the raw material treatment tank 1 and is circulated and stirred continuously, the air discharge hole 12 is not sufficiently closed, Even if the trash is temporarily blocked, a certain pressure of air is discharged through the air discharge hole 12 in the form of reverse osmosis, and the air is discharged from the small-area hole to the large- .

The gas discharging means 5 includes a discharge pipe 14 connected to the upper portion of the discharge section 20 side of the raw material processing container 1, a gas screw 17 inserted into the discharge pipe 14, As shown in Fig. A gas discharge hole 14a through which the gas is discharged is formed on the exposed outer circumferential surface of the discharge pipe 14. The gas pulley 18a connected to the end of the conveying shaft exposed by the gas screw 17 and the other end of the conveying shaft 2 of the conveying screw 2 at the discharging portion 20 side are rotated by the rotating means for rotating the gas screw 17, And a rotary belt 16 connecting the gas pulley 18a and the transmission pulley 18b to each other. The gas screw 17 is rotated by the rotating means having such a constitution, but the discharge pipe 14 always rotates together with the raw material processing vessel 1 irrespective of the rotation of the gas screw 17. In other words, the discharge tube 14 itself rotates together with the raw material processing container 1 without rotating.

Hereinafter, an operation state of the organic waste disposal agitator of the present invention constructed as described above will be described with reference to FIG. 1 to FIG.

The raw material processing container 1 and the feed screw 2 are rotatably rotated in opposite directions to each other by the rotary motors 8a and 8b so that the food waste and the food waste The same organic waste is continuously and continuously supplied in a predetermined amount, and the organic waste is added together with microorganisms and wood chips for fermentation of the organic waste.

Next, when air is introduced through the air inlet 11 by the blower 13 of the air introducing means 4, air is introduced into the raw material processing container 1 through the air discharge hole 12 formed in the conveying screw 2 So that oxygen necessary for fermentation is supplied.

2, the introduced organic waste is advanced by the feed screw 2 and the blade plate 21b of the feed blade 21 attached to the feed screw 2, But the conveying stirring plate 7 attached to the raw material treating cylinder 1 rotates while the raw material treating cylinder 1 rotates in the opposite direction, so that the circulation process of returning is reversed. That is, since the blade 21b of the conveying blade 21 is arranged obliquely toward the discharge portion 20, the blade 21b rotating together with the conveying screw 2 continuously conveys the organic material in the forward direction The transporting agitating plate 7 rotating along with the raw material treating tank 1 is moved in the direction of the arrow A and the transporting agitating plate 7 is tilted obliquely on the inner peripheral surface of the raw material treating tank 1, Push back the organic waste that is accumulated on the back side along the direction of the spiral so that it returns to the front side. The circulation of the organic waste in the raw material treatment tank 1 by the rotation of the raw material treatment tank 1 and the feed screw 2 and the rotation of the feed blade 21 and the conveyance stirring plate 7 reciprocates right and left Continue. As shown in FIG. 3, the organic matter garbage 15 at the bottom falls downward while hitting the conveying agitating plate 7 every time the raw material treating vessel 1 rotates and moves upward, Stirring is performed at the same time.

Even if a large amount of organic waste is dropped by the organic material 15 falling down and stirred while being continuously rotated and circulated, it is well dispersed in the raw material treatment tank 1, and the supply of oxygen by the air injection is smooth . As a result, the environment of the organic waste 15 in the raw material treatment tank 1 makes optimum conditions for fermenting the organic waste of the microorganisms, so that a large amount of organic waste can be fermented very efficiently and can be destroyed.

When 100% of the organic waste is charged by the fermentation elimination agitator of the present invention, only about 20% of the organic waste is finally left and the remaining is fermented and extinguished. The waste of 20% And then discharged through the discharge port 20a.

The water vapor and gas generated during the processing of the organic waste 15 are appropriately discharged to the outside of the raw material treatment tank 1 through the gas discharge hole 14a of the discharge pipe 14 as the gas discharge means 5 . At this time, the inlet of the discharge pipe 14 may be blocked by the organic waste, so that the gas discharge may not be smoothly performed. However, since the gas screw 17 continuously rotates to push the organic waste in the inlet outward, ), The steam and the gas are smoothly discharged without clogging.

On the other hand, as described above, since the organic material 15 falls down from top to bottom while circulating in the raw material treatment tank 1, the air is smoothly supplied between the organic materials 15, The discharge of the water vapor and the gas through the discharge pipe 14 as the means 5 is facilitated.

As described above, the fermentation and elimination agitator of the organic waste according to the present invention has been described with reference to the drawings. However, the present invention is not limited to the embodiments and drawings disclosed in the present specification, It is to be understood that various modifications may be made by those skilled in the art.
