Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for promoting composting of putrescible organic matter such as activated sludge sludge or livestock excrement.

In the conventional cutback, as shown in Figure 1, the stirring blade was rotated downward to scatter the putrefying organic matter (2) from the bottom to the rear, so the flying distance of the putrefying organic matter (2) was increased, and at the same time, the flying distance was increased. Since it changes significantly depending on the physical properties, the initial deposited state and the deposited state after turning back are markedly different, and as shown in FIG. 2, there is a drawback that the deposits are piled up in a dumpling shape (3) in some places. For example, when putrefying organic matter (2) is added to the fermenter (4), the water content is high, so the flying distance is short, but as the drying progresses, the water content decreases (-L7) The flying distance becomes significantly longer. After drying, the flight distance changes significantly due to the physical properties, such as becoming one length shorter, resulting in the formation of dumpling-shaped deposits (3).

Therefore, by turning back from the initial accumulation state shown by the solid line in Fig. 3, the dumpling-shaped accumulation state (3) shown by the dashed line in Fig. 3 is obtained.
Even if a
In order to prevent the stirring blade from overflowing, the left and right side walls (4) were formed at a considerably higher height than the direct diameter of the stirring blade (1).

Therefore, as shown in Fig. 1 and Fig. 3, a pair of sleeve tubes (61 (A a
) is installed vertically, and the rotating shaft (8) of the stirring blade body (1) is mounted on the lower end of the sleeve tube (6) via a bearing (7), and the rotating shaft (8) and the frame body (5) are connected to each other. Motor (9) installed in
The required high-speed rotation was obtained by connecting the sprocket QOI housed in the sleeve tube (6) with the chain (Ill).

Therefore, as the pair of left and right sleeves (6) move forward while being press-fitted into the accumulated putrefying organic matter (2), a considerable load is applied, causing the inconvenience that the wheels of the frame body (5) slip and prevent forward movement. Ta.

However, the sleeve tube (6) needs to be vertically installed very firmly, and the transmission mechanism for obtaining high-speed rotation of the stirring blade (1) also needs to be complicated and expensive.

In addition, it was necessary to provide expensive accessory equipment such as a screw conveyor to reduce the resistance force applied to the sleeve tube (6).

Therefore, although the conventional cutting method uses very expensive equipment, it has the disadvantage that dumpling-like deposits are formed in some places.

Since dumpling-like deposits are formed here and there, the initial deposit amount must be kept small, and the fermentation effect is accordingly poor.

The present invention provides a method for promoting composting of putrefying organic matter that can eliminate such conventional drawbacks, and is characterized in that the left and right side walls of the fermenter are formed low with a height shorter than the radius of the stirring blade. , a frame body for axially mounting the stirring blade body is slidably mounted on the low side wall, and a drive unit directly connected or connected to the rotating shaft of the stirring blade body outside the fermenter is attached to the frame body, The purpose is to rotate the stirring blade upward at high speed while advancing the frame body, scattering the putrefying organic matter from the upper part to the rear at a substantially uniform flying distance, and depositing it in substantially the same state as the state in which it was initially deposited.

In other words, the stirring blade is rotated upward at high speed to scatter the putrefying organic matter from the top to the rear over a nearly uniform flying distance, so that it is deposited in almost the same state as it was originally deposited, and even further than the stirring blade. Even if the left and right side walls are low, there is no need to worry about overflowing the putrefactive organic matter due to turning back, and even if the left and right side walls are low, it is possible to deposit the putrefactive organic matter that has been accumulated at a high A frame body equipped with a drive unit that is directly connected or connected to the rotating shaft of the stirring blade body is placed on the side wall outside the fermenter, and pressure advances into the putrefactive organic matter that is conventionally located and accumulated inside the fermenter. The forward movement of the stirring blade is also improved by completely eliminating the transmission mechanism such as the sleeve case, chain, and sprocket.

Furthermore, the composting promotion method of the present invention will be explained in detail with reference to illustrative drawings.

FIG. 9 is a diagram showing the operating state of the apparatus for carrying out the method of the present invention as seen from the front side and FIG. is formed with a length shorter than the radius of the stirring blade (23).

) is mounted on the shaft via a bearing (2!9).

C26) is a drive unit mounted on the frame body (24) on the outside of the fermenter (2I), and is directly connected to the rotating shaft 03a). This drive section (c) is formed by a motor, a speed reducer, a coupling, etc. Note that the drive unit (a) may not be directly connected but may be connected outside the fermenter Qυ.

Numeral (27) denotes a large number of stirring blades arranged in parallel, the base side of which is bent toward the rear (27a), and the tip of the blade (27a) is formed with a scraping portion Q7b) that points toward the center.

Therefore, the left and right side walls where the frame body e4) is formed low @
While moving forward above the fermenter (21), the strong rotational driving force of the drive unit (26) directly connected to the rotating shaft (13a) moves the stirring blade (23) upward at high speed as shown in Figure S. As the rotor rotates, the rotting organic matter (0) that accumulates higher than the stirring blade C23 is scattered at a nearly uniform flying distance from the upper part to the rear as shown by the arrow, and the original deposit (C) is scattered as shown in Figure 6. )・It is deposited in a state substantially similar to that in (a).

Since the composting promotion method of the present invention is as described above, it exhibits the following effects.

That is, first, the left and right side walls (22) of the fermenter (21) are formed low with a height shorter than the radius of the stirring blade (23), and the stirring blade (23) is mounted on the lower side wall (22). The frame body (24) is slidably mounted and the fermentation tank (

The frame body (24) is moved forward while the stirring blade body (23) is rotated upward at high speed to remove putrefactive organic matter (
Since this is a composting promotion method in which 0) is scattered at a nearly uniform distance from the top to the rear and deposited (4) in approximately the same state as it was initially deposited (C), the compost is highly deposited throughout. It is an excellent method to promote composting because it can achieve a high fermentation effect by efficiently cutting back organic matter while maintaining the same state, and it is possible with a simple and inexpensive device. .

Second, since the left and right side walls (23) can be formed low and have a length shorter than the radius of the stirring blade (23), the drive unit (
c) Since it is directly connected, the conventional transmission mechanism such as the one-sleeve case and chain sprocket, as well as the attached devices such as the screw conveyor, are removed, so the conventional 773 position is also cheaper, and there is no resistance due to press-fitting the sleeve tube, so the stirring blade (The forward movement of the second floor will also be greatly improved.

Thirdly, the direct drive force causes the stirring blade (23) to rotate upwards at a high speed and powerfully, and while moving smoothly forward without any resistance from sleeves, etc., the stirring blade (23) is able to remove the accumulated organic matter ( (c) is also deposited in almost the same state.Since the turning is performed in such a way that the turning ability and the efficiency thereof are significantly increased, and the promotion of composting is extremely high.
