Description

DETAILED DESCRIPTION OF THE INVENTION The present invention applies not only to seaweed raw materials that have been cut, washed and dehydrated in the previous process, and seaweed raw materials that have been further aged and dehydrated, but also to seaweed raw materials that have been harvested, washed and dehydrated in the previous process, This invention relates to a quantitative feeding device for raw seaweed such as dehydrated seaweed algae.

The first objective is that this type of raw seaweed, due to its nature,
Even though it is drained and dehydrated in the previous process, it is difficult to maintain a constant moisture content, and raw seaweed is normally supplied to the raw material tank with excess moisture unevenly contained. Raw seaweed containing water accumulates in the raw material tank, often impeding the quantitative feeding of raw seaweed to the next process.

On the other hand, raw seaweed has strong adhesive properties and tends to stick to the inner walls of raw material tanks and rotating blades, so a small amount of water is poured in to reduce the adhesive force and often maintain smooth feeding. .

This method has also been found to have disadvantages, such as changing the moisture content of raw seaweed and hindering its quantitative feeding.

Therefore, in the present invention, regardless of whether the raw seaweed supplied to the raw material tank is drained, whether it is in a dehydrated state, or whether water is poured into the raw seaweed after being supplied to the raw material tank, in order to ensure the constant feeding of the raw seaweed, The feeding guide gutter for raw seaweed installed at the bottom of the raw material tank has a porous, mesh, or slit-like drainage and dewatering structure, and the screw feeder for horizontal transfer of raw seaweed installed in the guide gutter is rotated.

'Thus, the operation of the continuous and quantitative feeding device for the seaweed raw material X1 in the above embodiment will be explained.

First, seaweed raw material X1 obtained by cutting, washing, and dehydrating the collected seaweed raw algae in the previous process, or seaweed raw material X1 obtained by cutting, ripening, and dehydrating, is charged into the raw material tank 1 and stored therein, and the drive motor 18 , 20, respectively.

Then, the driving force of one motor 18 is transferred to the driving gear 19,
Power is transmitted via the driven gear 17a on the rear side and the driven gear 17 on the front side, and the screw feeder 5 for the seaweed raw material X1
The sending device 1212a rotates relatively several times or more in the direction of arrow A (forward direction) in FIG. Repeat the operation.

As a result, the seaweed raw material X1 is fed into the guide trough 2 at the bottom of the raw material tank 1 and its screw feeder 5.

Further, the driving force of the motor 20 which is externally powered is the driving pulley 21,
Power is transmitted to the screw feeder 5 via the belt 22 and the driven pulley 7, and the screw feeder 5 rotates in the direction of arrow B in FIG. Quantitative horizontal transfer.

At this time, the seaweed raw material X1 to be fed is slimy and highly sticky, so it is pasted not only on the front and rear inner walls of the raw material tank 1, but also on the shaft 5a and spiral blades 5b of the screw feeder 5. This causes a phenomenon that prevents continuous and quantitative feeding of the seaweed raw material X1 in the raw material tank 1.

Therefore, when driving the motors 18, 20, the solenoid valves 9, 24
b are opened respectively, and as the solenoid valves 24b are opened, a small amount of water Y is applied to the front and rear inner wall surfaces of the raw material tank 1, and the front, rear, left and right inner wall surfaces from the water sprinkling ports 24a of the water sprinkling pipes 24. Therefore, the delivery device 12 for the seaweed raw material X1
, 12a to ensure smooth delivery of the seaweed raw material X1 to the guide trough 2 and screw feeder 5.

In addition, as the solenoid valve 9 opens, a small amount of water Y oozes out from the group of small holes 11 in the shaft 5a of the screw feeder 5 or the spiral blade 5b of the shaft 5a, and this water Y flows into the screw feeder. 5 and the seaweed raw material X1, thereby ensuring smooth and continuous feeding of the seaweed raw material X1 sent to the screw feeder 5.

One power, watering from the watering port 24a, screw feeder 5
Water leakage from the 11 groups of small holes increases the water content of the seaweed raw material
Among these, in the case of insufficiently dehydrated seaweed raw material X1, its moisture content is further increased.

However, the guide gutter 2 itself is designed to be able to drain and dewater freely.
In addition, the guide trough 2 has engaging portions 2a arranged in parallel in the left and right force directions.
t 2 b t 2 c are formed.

Therefore, the seaweed raw material X1 sent to the guide trough 2 is pressed against the guide trough 2, which can be freely dewatered, under the action of the rotation pressure from the screw feeder 5. While draining and dewatering the seaweed raw material X1 into the gutter 23, the seaweed raw material X1 is continuously and quantitatively fed toward the guide tube 2 at the left end of the guide gutter 2.

The seaweed raw material X1 sent into the guide tube 3 is
Under the influence of a slight leakage from the screw feeder 5 of the box frame 4 and the box frame 4, water is sent to the outlet part while weakening the adhesion force with the surface of the shaft rod 5a of the left end part and the surface of the spiral blade 5b, and further water is sent to the end. The seaweed raw material X1 is continuously and quantitatively fed downward from the box frame 4 portion and falls into the raw material liquid tank 28 of the seaweed mixture X2.

In response to the continuous feeding and dropping of the seaweed raw material The liquid is ejected into the tank 28.

As a result, seaweed raw material X1 is diluted with water Y and stirred to form a seaweed preparation liquid X2 of a desired concentration.

This is fed by a feed pump 30 driven by a motor 31 through a feed hose 32 to a subsequent process of making seaweed.

In addition, the manual operation bundle 10 is used when the screw feeder 5 is used to prepare the priority seaweed liquid mixture It is useful to artificially increase the rotational feeding force of the seaweed raw material X1.

According to the first example consisting of the above word structure, seaweed raw material X1
Smoothly and reliably achieves continuous and quantitative feeding of seaweed raw material The mixture is manufactured into a mixture X2.

FIG. 5 shows a modification of the guide tube 3 shown in the first embodiment, in which the guide tube 3 has a double structure, and its inner wall surface 3a can be freely drained and dewatered in a porous, mesh, or slit shape. The structure is as follows.

3b is a drain port provided at the lower end of the guide tube 3, to which a drain hose 3c is connected.

Therefore, a spiral blade 5b at the end of the screw feeder 5 is rotatably circumscribed on the inner wall surface 3a of the guide cylinder 3.

Thus, the seaweed raw material X is fed to the outlet of the raw material tank 1.
1 is the rotational pressure of the screw feeder 5 (thereby, excess water is drained and dehydrated also from the inner wall surface 3a of the guide tube 3, thereby achieving a more complete dehydration effect of the seaweed raw material X1).

Incidentally, in the above-mentioned embodiment, the metering feed device for the seaweed raw material X1 in the mixing and manufacturing device for the seaweed liquid mixture X2 has been explained in detail, but this is described in detail in the Utility Model Application Publication No. 55-1145 filed by the present applicant.
A feeding and cutting device for collected seaweed raw algae as shown in Publications No. 93-114595, etc., specifically, a feeding guide gutter is provided at the bottom of the raw algae tank, and a hollow shaftless horizontal transfer screw is installed in the guide gutter. In a device in which a conveyor is rotatably supported, the guide gutter is formed into a porous, mesh-like, slit-like, etc. drainage and dehydration structure, and excess water contained in the raw seaweed algae that has been washed, drained and dehydrated in the previous process is removed. The gist of the present invention is not changed in any way by draining and dewatering the seaweed using the rotary pressure of the screw conveyor as a medium to cope with the quantitative feeding of the seaweed.

Therefore, according to the present invention, not only cut seaweed raw materials but also any raw seaweed such as collected seaweed raw algae are drained and dehydrated in the process of being sent to the outlet of the raw material tank. This enables fixed-quantity feeding by discharging excess water contained in seaweed.

As described above, the present invention provides a guide gutter at the bottom of the raw material tank, rotatably supports a screw feeder for lateral transfer of raw seaweed in the guide gutter, and the screw feeder is rotated to feed the material to the outlet of the raw material tank. In an apparatus configured to feed raw seaweed, the guide gutter is formed in a porous or slit-like drainage/dehydration structure, and excess water contained in the raw seaweed is drained by the rotation pressure of the screw feeder.
Since the raw seaweed metering feed device is configured to be able to dehydrate, as the raw seaweed is fed toward the outlet of the raw material tank, the moisture content of the raw seaweed is averaged, and the excess moisture contained in the raw seaweed is The water is effectively drained and dewatered using the rotational pressure of the screw feeder, and as a result,
It can usefully cope with quantitative feeding of raw seaweed.

Moreover, one or two engagement guide parts for the raw seaweed are installed in the guide gutter.
With the above arrangement, various effects can be brought about, such as being able to achieve even better draining and dehydration of raw seaweed.
