TECHNICAL FIELD OF THE INVENTION
The present invention relates to an improvement of a device for turning over a raw material in a fermentation device for sewage sludge and the like. In particular, the present invention does not provide a device capable of uniformly turning over a raw material even when the turning device turns in a loop-shaped fermenter. It is assumed that.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there has been known an apparatus in which a scoop-type reversing device circulates through a fermenter configured in a loop shape when viewed in a plan view and transports and ferments the raw material in the tank while reversing. JP-A-8-67588 is an example. In the invention disclosed in JP-A-8-67588, the turning device mounted on a bogie reciprocates in a linear portion of the fermenter, and turns around an inner end of the circular portion.
[0003]
[Problems to be solved by the invention]
However, in the case where the raw material is turned back in the loop-shaped fermenter as described above, in the portion where the turning device turns, the raw material at the center of the turning is thrown toward the outer peripheral portion, and the outer peripheral portion is much and the central portion is turned. And the distribution of the mortar-shaped raw material is reduced. FIG. 1 shows this situation. In the figure, the raw material thrown backward at point A only needs to fall to a symmetrical position B with respect to the center line X. When the force is applied, the material falls to the point C, and the raw material is shifted to the outer peripheral portion, so that uniform turning cannot be performed.
[0004]
[Means for Solving the Problems]
The present invention has solved the above-described problem at the time of turning of the turning device, and the gist of the present invention is that the turning device of the raw material in the fermenter, which is formed into a loop in a plan view, is used. In the fermenter that is to be circulated, a plurality of reversing plates of the thrown raw material are provided at the falling portion of the thrown raw material on the side opposite to the traveling direction of the turning device, and these reversing plates are released in conjunction with the turning of the turning device. It is supported on the machine frame of the turning device so as to rotate in a direction to reverse the thrown raw material toward the center of rotation.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
That is, when the turning device starts turning, the reversing plate turns in conjunction with the turning device to reversely move the thrown raw material toward the turning center, thereby filling the recess formed in the turning center, and turning the turning unit. In this case, the raw material can be uniformly turned back. The turning mechanism of the reversing plate interlocked with the turning start of the turning device will be specifically described with reference to the drawings.
[0006]
【Example】
FIG. 2 is a plan view of the fermenter 2 for explaining the patrol state of the turning device in the fermenter of the turning device 1. The turning device 1 is supported on a swivel 4 mounted on a bogie 3. With the reciprocating movement of the cart 3, the straight part of the fermenter 2 goes straight along the arrow as shown by the arrow, and the left and right circular parts turn around the inner end thereof (arrow Y). And cut back the raw materials. In both the straight section and the turning section, the scooped raw material is thrown backward in the traveling direction and cut back.
[0007]
Next, FIG. 3 shows a side view of the turning device 1 in an open state. Reference numeral 5 denotes a scoop belt to which a large number of scoops 5a are attached, the lower end of which is brought close to the bottom surface 2a of the fermenter 2. At the same time, its upper end is supported on a swivel 4 mounted on the carriage 3. Reference numeral 6 denotes a drive shaft of the scoop belt 5, and reference numeral 7 denotes a drive motor. The turning center of the turning device 1 is the inner end of the turning device 1 as shown in FIG. In FIG. 3, reference numeral 8 denotes a supporting frame of the above-described reversing plate 9 and 10 denotes a pair of supporting rods of the reversing plate 9 provided in a substantially vertical shape.
[0008]
Next, the support structure of the reversing plate 9 will be described in detail with reference to FIGS. The lower ends of the pair of support rods 10 are connected by a lower fixed rod 11 as shown in FIG. 4, and both ends of the lower fixed rod 11 extend from the pair of support rods 10 at an obliquely rear upper portion. An upper fixed rod 12 fixed to the extended arms 10a and 10b is provided. As shown in FIG. 5, the reversing plate 9 has a lower edge 9a and an upper edge 9b pivotally supported by a lower fixed rod 11 and an upper fixed rod 12, and an axis Y connecting the upper and lower pivots is pivoted. It can be rotated as. The angle between the axis Y and the vertical line (the hanging support rod 10) is about 45 °.
[0009]
The free end 9c on the rear side of the reversing plate 9 is pivotally supported by the operating rod 13, so that the reversing plate 9 rotates about the axis Y by the left and right movement of the operating rod 13. At the outer end of the operating rod 13, a guide rod 13 a protruding outward from the turning radius when the turning device 1 is turned is attached, while the innermost reversing plate 9 has a base end thereof. The end of a return rod 14 bent in a key shape pivotally supported by the support rod 10 is brought into contact with the reversing plate 9 in the linearly advancing section so as to return to the normal posture.
[0010]
Since the device according to the present invention is configured as described above, when the switching device 1 comes to the circular portion of the fermenter 2, the guide rod 13 a of the operating rod 13 is moved to the circular shape of the fermenter 2 as shown in FIG. The free end 9c of the reversing plate 9 is pressed against the inner wall surface 2b of the shape and is rotated about the axis Y.
[0011]
That is, the reversing plate 9 rotates clockwise around the axis Y inclined at about 45 ° with respect to the vertical line (the direction in which the support rod 10 hangs down), and rotates so that the reversing surface faces the center of rotation. The raw material that has been thrown toward the outer peripheral portion by the turned reversing plate 9 is returned to the center of rotation. Therefore, it is possible to make a uniform turning back without forming a recess in the raw material at the center of rotation.
[0012]
Next, when the turning of the turning device 1 is completed and the turning device 1 comes to the straight running portion, the return rod 14 pushed out by the inversion plate 9 at the inner end at the time of turning comes into contact with the central partition 2c of the fermenter 2. The reversing plate 9 at the inner end is pushed to return the rotated reversing plate 9 to the original posture. That is, in the linearly advancing section of the turning device 1, each reversing plate 9 is folded in parallel, and at this time, each reversing plate 9 can crush the falling raw material.
[0013]
【The invention's effect】
As described above, the apparatus according to the present invention, in a fermentation apparatus in which the switching device circulates in the loop-shaped fermenter, can uniformly switch the raw material without biasing even in the swirling part of the switching device. In addition, the raw material can be crushed by the reversing plate even in the straight traveling section, and the operation of the reversing plate is automatically performed, thus completely solving the problem of this type of the conventional apparatus.
