Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous dewatering apparatus for vegetable waste, and more particularly to a method for continuously dewatering a large amount of leafy and root vegetable waste generated from a vegetable processing plant. The present invention relates to a continuous dewatering device for vegetable waste that can be reduced in capacity.

[0002]

2. Description of the Related Art Conventionally, vegetable waste generated from vegetable processing plants as industrial waste has been buried in soil as it is, dehydrated or dried or incinerated, and then disposed of as fertilizer. At this time, as the dewatering means for vegetable waste, for example, a leaf vegetable squeezing device described in Japanese Utility Model Publication No. 4-17029 or a device provided with a known spiral pressing mechanism is used as the dewatering device.

[0003]

However, the apparatus described in Japanese Utility Model Publication No. 4-17029 is a device in which boiled spinach and spring chrysanthemum are housed in a container body, squeezed by a pressing piston, and drained. Therefore, raw hard vegetable waste cannot be pressed sufficiently and is not suitable for dehydration. In addition, there is a disadvantage that the processing efficiency is poor because the mechanism performs processing for one batch.

Further, as an apparatus provided with the above-mentioned spiral pressing mechanism, a spiral conveying means and a pressure receiving plate having perforated holes are arranged side by side in a cylindrical processing tank to convey vegetable waste in the cylindrical processing tank. In this case, it is possible to obtain a relatively good dewatered vegetable waste within a short period of time by pressing against the pressure receiving plate and pressing and dewatering. However, the dewatering device of this mechanism often causes the roots of root vegetables mixed in the vegetable waste to block the holes of the pressure receiving plate or clog the holes,
As a result, there is a drawback that the vegetable waste after dehydration cannot be sent out from the cylindrical treatment tank and the continuous dehydration treatment of the apparatus has to be stopped. In addition, there is a problem that an extra processing operation for removing vegetable waste in the processing tank is required.

[0005] The present invention has been made to solve such a problem, and even when raw vegetable waste including tuberous roots of root vegetables is subjected to dehydration treatment, the capacity can be sufficiently dehydrated. It is an object of the present invention to provide a vegetable debris continuous dewatering device capable of reducing as much as possible and continuously taking out dewatered vegetable waste from the dehydration device.

[0006]

That is, a continuous dewatering apparatus for vegetable waste according to the present invention comprises a spiral conveying means, a wing-shaped pressure feeding means and a helical conveying means in a hollow inside of a cylindrical processing tank having an input port for vegetable waste at a rear portion thereof. A cutting blade is sequentially provided, and a pressure receiving filter plate is fixedly provided adjacent to the rotary cutting blade at the tip of the cylindrical processing tank, and the pressure receiving plate has a wide opening on the pressure receiving surface side. In addition, a plurality of substantially funnel-shaped slots having a cross section whose other side is narrowed are provided. By adopting such a configuration, even if roots such as radishes and carrots are mixed in the vegetable waste, the portion pressed and fitted into the slot of the pressure receiving filter plate is formed by the rotary cutting blade. It can be cut off as small pieces and pushed out of the pressure filter plate without clogging the slots. At that time, if the shape of the slot is made into a semi-funnel shape in cross section, the cutting function becomes better with the vertical wall of the funnel part of the slot and the rotary cutting blade, and the sharpness can be sharpened further, so the clogged in the slot The tuberous root may be more easily cut into pieces and extruded through the slot. Furthermore, by making a part of the peripheral wall of the cylindrical processing tank have a perforated or meshed structure, it is possible to discharge the sap generated by the squeezing on the way, and the sap and the scum can be automatically separated and collected, and the subsequent processing can be performed. It is good because the work is also easy.

FIG. FIG. 8 is an explanatory view showing a state in which the tuberous root is fitted into a semi-funnel-shaped slot formed in the pressure receiving filter plate. FIG. 9 is a plan view showing the shape of the wing-shaped pumping means, and FIG.
0 is a plan view showing another embodiment of the pressure receiving filter plate. 1 to 3, a continuous dewatering device 1 for vegetable waste
Has a configuration in which a cylindrical processing tank 4 having a vegetable waste input port 2 at a rear portion and a dewatered vegetable waste outlet 3 at a front end side is supported by a base 5. The cylindrical processing tank 4 is rotatable with a helical conveying means 6, a wing-shaped pressing means 7 and a rotary cutting blade 8 in the hollow inside with a rotating shaft 9 inserted through the cylindrical processing tank 4 as a support shaft. I have been supported. The pressure receiving filter plate 10 is provided with a plurality of substantially funnel-shaped slots 11 with a wide opening on the pressure receiving surface side and a narrowed other surface side. The helical conveying means 6 conveys the vegetable waste input from the vegetable waste input port 2 of the hopper port to the discharge port 3 while squeezing the vegetable waste. Is connected to the next blade-shaped pressure feeding means 7. The vegetable waste conveyed by the spiral conveying means 6 is further compressed by the wing-shaped pressurizing means 7 and fixed rods (fixed teeth) projected into the cylindrical processing tank 4.
13 and the rotating blades of the blade-shaped pressure feeding means 7 are kneaded and finely divided. Further, the fixed rod 13 prevents co-rotation during the transportation of the vegetable waste, and also functions as a baffle plate for pressure-feeding the vegetable waste. Therefore, the fixed rod 13 is preferably mounted so as to be able to advance and retreat into the processing tank 4 by means of screw feed or the like, so that the length of protrusion can be adjusted so that the feed amount of vegetable waste and the cutting state by compression and friction can be controlled. Is desirable.

[0008] As described above, the vegetable waste which has been pressed and crushed and which has been sufficiently crushed is replaced with the next rotary cutting blade 8.
And further sent out from the slot 11 of the pressure receiving filter plate 10 to the waste port 3. On the other hand, the roots of root vegetables, etc., which are not sufficiently ground, are directly filtered through a filter plate 10.
However, as it is, the opening of the slot 11 is closed in a state where a part thereof is fitted into the slot 11, and the delivery to the disposal port 3 is temporarily disabled. Become. At that time, the root portion that could not fit into the slot 11 is cut off by the rotary cutting blade 8 disposed adjacent to the pressure receiving filter plate 10, and the rotation of the cutting blade 8 causes the outside of the slot 11 to be cut off. The cut portion is removed from around the opening of the slot 11. Thus, the fragment portion of the root A inserted into the slot 11 receives the pressure of the spiral conveying means 6 and the blade-shaped pressure feeding means 7 as it is, and is pressed out to the waste port 3. Thus, the vegetable waste input from the input port 2 is squeezed and shredded even if the root vegetables are mixed, and is sequentially sent out from the slot 11 of the filter plate 10 to the waste port 3.
At this time, by forming a part of the bottom wall of the cylindrical processing tank 4 with a porous punching plate or the like (not shown), only the squeezed liquid generated at the time of squeezing the vegetable waste is drained from the porous part to the processing tank. 4 can be discharged to the outside.

As shown in FIGS. 5 and 8, the shape of a substantially funnel-shaped slot 11 formed in a filtration plate 10 is formed as a semi-funnel-shaped slot 11 having one inner wall made vertical. This is desirable because the cutting blade 8 disposed in sliding contact with the filter plate 10 becomes sharper. The reason for this is not clear, but since the root portion A fitted into the slot 11 at the time of cutting is firmly supported by the vertical wall of the slot 11, FIG.
It is presumed that it is possible to receive all the cutting stress of the cutting blade 8 from the direction of the arrow N in the middle. The funnel shape according to the present invention includes all the shapes in which the opening on the pressure receiving surface side is widened and the other surface side is narrowed irrespective of the present embodiment. In the figure, reference numeral 14 denotes a drainage hole for collecting and discharging squeezed liquid discharged from the perforations of the punching plate, and reference numeral 17 denotes a control panel for controlling the driving of the vegetable waste dewatering device 1.

[0010]

According to the continuous dewatering apparatus for vegetable waste of the present invention, a plurality of substantially funnel-shaped slots are formed in a pressure receiving filter plate for receiving and filtering compressed vegetable waste while continuously transporting the same. Since the rotary cutting blade is adjacent to the pressure receiving surface side of this pressure receiving filter plate, even if roots of root vegetables are mixed in the vegetable waste, the root hole is cut by the rotary cutting blade to form a slot. It can be taken out together with other vegetable debris without clogging. Therefore, the work of removing the vegetable debris in the apparatus after the dehydration becomes unnecessary, and the work efficiency is improved. In addition, by forming the bottom wall of the cylindrical processing tank with a porous punching medal, the squeezed liquid generated during the pressing of the vegetable waste can be separated from the dehydrated vegetable waste and discharged, so that it can be used as industrial waste. The amount of vegetable waste can be greatly reduced.
