Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of operating a composting apparatus for fermenting municipal waste, sewage sludge, livestock 11'/waste, etc. to produce compost.

The present applicant previously filed a patent application No. 1983 65249 L'r〈
In JP-A-55-158193), he proposed a composting method in which materials deposited in a fermentation plant are simultaneously stirred and avoided by a rotating paddle that moves in a zigzag pattern within the fermentation plant. In this J(I) fermentation method, one end of the fermentation plant serves as a raw material supply section, and the narrow end opposite to this serves as a compost take-out section.
The fertilizing source is moved toward the extraction section by a rotating paddle, and aerobic fermentation proceeds during this time. In this case, the movement of the material by the rotary paddle first starts from the take-out part side, and the rotary paddle moves in a zigzag pattern until it reaches the supply part 131, and then passes through the return path where the material 111 is not stacked and returns to the take-out part. to prepare for the next stirring operation.

Therefore, the Jftft membrane facility J, which implemented this ``11 fertilizer method,'' has 11 f of material along the nil fermentation, and 4 f of the return passage without stacking, which saves a large site area. I need. Also, since this return passage needs to be at least wide enough to pass through the rotating paddle, the span of the longitudinal girder becomes much larger and the construction cost is reduced by 1! ′♂ It has also been proposed to provide a device that can move the rotating paddle up and down in the longitudinal beam or the moving device for the rotating paddle in order to improve the shortcomings of the above, but the device that can move the rotating paddle up and down is itself an effective device 6. In addition, the load on the longitudinal girder would increase, so this would not be an effective improvement after all.

The present invention was invented with the aim of obtaining a method of operating a composting head that eliminates the drawbacks of the conventional composting method. The purpose of this invention is to provide a method of operating a fermentation system that can perform a good fermentation process with a simple equipment configuration.

In order to achieve the objective 1), the present invention provides a fermentation tank having a substantially rectangular horizontal surface, vertical rails arranged on two opposing sides of the 1li1 fermenter, and vertical rails arranged on the opposite sides of the 1li1 fermenter. a vertical girder arranged across the vertical girder, a moving device that is in contact with the vertical girder and moves horizontally along the vertical girder, and a rotation surface of the moving device that is substantially perpendicular to the lateral t'r direction of the moving device; and a reversible rotary paddle supported on the moving device so that
"Using a fattening device, the rotary paddle is moved throughout the fermentation tank by a longitudinal movement in which the longitudinal beam moves on the rail and a transverse movement in which the moving device moves transversely along the longitudinal beam." Move in the shape of a ``shut down and stir the monthly rate in the fermenter 8J''
In the operating method of the one-hill fertilizer equipment, the direction of rotation of the rotary paddle is limited to a direction in which the rotary paddle is moved over the top of the rotary paddle in a direction opposite to the direction of movement of the longitudinal girder, and a direction in which the longitudinal girder is The above-mentioned moving and stirring operations are performed during both the processes in which the girders reciprocate and cover the rails.

Therefore, the present invention is applicable to batch type 1!11 fermentation treatment.

According to the present invention, the shrine 1'51 that is to be the raw material for compost is 117. Because it receives good 1'F stirring from the paddle,
Consolidation+;1. (If ! is not advanced, it will be multiplied by constant softness.) The ventilation resistance of 4T, GJ, and A, where air is supplied from the floor of the fermentation tank with tit, is extremely small. In addition, the surface area of 11L [; 1 is extremely large, so contact with air is made in a suitable manner, making ideal aerobic fermentation possible. Stirring 11'' exerts a strong shearing force on the material, which promotes the fragmentation of each material, resulting in uniform fermentation throughout the month.However, such The functions and effects can also be seen in the inventions of Japanese Patent Application Nos. 54-65249 listed in item 11, and are not necessarily unique to the present invention.

In the present invention, it is arranged along the two opposite sides of the fermentation 4f'+.
In both the processes in which the longitudinal beam moves back and forth on the vertical rails, the material is stirred by a rotating paddle,
Since we will be moving, we will use f■1 turn paddle paddle lifting machine 1fa.
The return passage provided to return the rotary paddle to its original position is completely removed (unnecessary). It can be used effectively.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of a fertilizing device 111 used in the present invention, in which 1 is a fermentation tank with a substantially rectangular plane, and rails 2.3 are arranged along opposing 2) 22 of this fermentation tank 1. A vertical ti girder 4 is placed in this 1-nord 2.33. Further, on the vertical beam 4, a transverse transfer device 15 is placed one step above the vertical beam 4, and a rotary paddle 6.7 is supported by this moving device 5. The fermenter 1 is surrounded on all sides by peripheral walls 8.9.10.11.

In FIG. 1, the moving device 5 is moved transversely along the longitudinal beam 4 in the direction from the wall 11 to the wall 10, and the rotary paddle 6.7 is rotated toward the IAAl1 wall 8 side on the wall side. Move it, and then rotate it in the direction of rotation so that the discrimination to move goes beyond the top of the rotating paddle [! It is being

When the rotary paddle 6 reaches just before the wall 10, the longitudinal beam 1 moves a predetermined distance N]() in the direction of the wall 9, and the moving device 5 moves toward the wall 9 in the opposite direction. The material starts moving in the direction of the wall 11 from 10, and the material is stirred and moved by rotating paddles 6.7.

In addition, Fig. 2 t is a cross section taken along the j-1 line in Fig. 1, and the fermentation tank 1 is loaded with materials 12 higher than the direction of the rotary paddle 6. A perforated plate 133 is arranged so that air is guided through a blower (not shown). The moving device 5 moves in a reciprocating line 4s1η on the vertical beam by a reversible motor 14, and when its tip reaches the position of the stopper 15, 15' on the vertical beam, the traverse stops. -ru. The rotary paddle 6.7 is rotated by the reversible motor 16, and is integrally connected to the moving device 5 by the reversible motor 16 and the J arm 17. In addition, the supply and removal of materials is carried out by making any of the walls 8.9.10.11 removable and using a plutoge or a shovel robe.

Next, the locus of movement of the rotary paddle in the present invention will be explained with reference to FIGS. 1 and 3. Figure 3 shows the trajectory of the rotating paddle on the i11 fermenter 1 having a rectangular plane, where 8.9.10.11 is the wall surrounding the fermentation tank 4!1. Assuming that 1v1 stirring starts from point A1,
First, move the moving device 5 from point A1 to 8 without moving the vertical girder 4.
The material is moved in the direction of one point, and at the same time the rotating paddle 6.7 is rotated to move the material from the wall E3 side to the wall 9 side over the 1111Φ paddle 6.7. Next, the moving device 5
When reaches the 81st point, stop the traverse device of the moving device 5 and move the longitudinal girder 4 in the direction from the wall 9 to the wall 8 so that the moving device 5 comes from the 81st point to the 82nd point. .

Next, the longitudinal girder 4 is stopped and the moving device 5 is moved horizontally from the point 82 to the point A2.

In this way, the rotating paddle 6.7 is rotated until the moving device 5 reaches the starting point A1 to the ending point A14, and the material deposited in the fermentation tank 1 is completely transferred from wall 8 to wall 9. Stir and move in the direction of.

A solid line 18 shows the locus of movement of the moving device 5 and the rotary paddle 6.7 at this time.

In this way, after agitating the 1" piled 4") in the fermentation tank 1, the next step is to stir 8" from the Δ1/l point.
14 Move the device 5 across the ground and stir and move the material 1 in the opposite direction.

Therefore, reverse the direction of rotation of the rotating paddle 6.7 and move the rotating paddle 6.7 in the direction of 1% fi I3 from the wall 9. Rotate the rotating paddle 6.7 in the direction of (↓

Therefore, no matter which direction the rotary paddle rotates, if the material in the fermentation tank is rolled 111 above the rotation center 23 of the bucket 20, the material will be placed above the rotation axis of the rotary paddle. The person will be transferred to the other side by jumping over the border.

In FIG. 4, the four ribs 21 are arranged as symmetrically as possible about the axis 20, but this number can be set as desired.

The rotating paddles 6.7 shown in Fig. 2 are the same as the rotating paddles shown in Fig. 4 installed in three stages with different phases. It may be 1 or 3 or more stages.

In FIG. 4, the scrapers 22a and 22h are fixed to the rib 21 by bolts and nuts (not shown), but this is because the scrapers 22a and 22b are fixed to the ribs 21 by INN J'l' of the grinder 1. This is because they are designed to be easy to replace since they wear out and gradually deform.

Further, in FIG. 2, the rotary paddle 6.7 and the drive 1 filter 16 are provided at the lower part of the arm 17, but they can also be provided on the moving device 5.
This has the advantage of making Shiku's lifespan longer since the atmosphere of being attacked is improved. In addition, as a means of supplying air from the floor of the fermentation tank, as shown in Figure 2 1: In addition to using a perforated plate, a number of holes are installed on the circumferential surface of the pipe. It may be an air diffuser type installed on the surface, or it may be other air supply means.
