Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a metering device for feeding laver raw materials in a mixing and manufacturing device for laver raw materials.

The purpose of this is that it is difficult to maintain a constant moisture content of the seaweed raw material even though it is dehydrated in the previous process, and it also reduces the adhesion of the seaweed raw material to the inner wall of the raw material tank, rotating blades, etc. However, in view of the fact that even a small amount of water poured in order to ensure smooth feeding can change the moisture content of the seaweed raw material, and in turn, misalignment that may impede the quantitative feeding of the seaweed raw material, the present invention has been developed. In this system, the excess moisture contained in the seaweed raw material is effectively drained and dehydrated using the rotational pressure of the spiral blade, rotary vane, etc. provided at the bottom of the raw material tank, and this allows for quantitative feeding of the seaweed raw material.

The operation of the device for continuously and quantitatively feeding the seaweed raw material X1 in the first embodiment will now be explained.

First, the seaweed raw material X1 that has been cut, washed, and dehydrated from the collected seaweed raw algae in the previous process, or the seaweed raw material X1 that has been cut, aged, and dehydrated, is charged into the raw material tank 1 and stored, 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 through 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 delivery device 12.12a rotates several times or more in the direction of arrow A (positive direction) in FIG.
Repeat the operation of reversing 2 to 3 times in the direction of the arrow (reverse direction).

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 other motor 20 is applied to 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 sticks not only to the front and rear inner walls of the raw material tank 10, but also to the shaft rod 5a and spiral blade 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 valve 24b is opened, a small amount of water Y is applied to the front and rear inner wall surfaces of the raw material tank 10 and the front, rear, left and right inner wall surfaces from the water sprinkling ports 24a of the water sprinkling pipes 24 along the inner wall surfaces. The seaweed raw material
Seaweed raw material X to guide gutter 2 and screw feeder 5
1 to ensure smooth delivery.

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.

On the other hand, 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 The moisture content of the opaque seaweed raw material X1 is further increased.

However, the guide gutter 2 itself is designed to be able to drain and dewater freely.
Moreover, the guide trough 2 has a recess 2a in the left and right direction.

2b and 2c 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 rotational pressure of 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
Due to the slight water leakage from the screw feeder 5 of the box frame 4 section and the box frame 4 section, the adhesion force between the shaft rod 5a surface of the left end section and the spiral blade 5b surface is weakened, and as a result, the water continues downward from the box frame 4 section. In addition, quantitatively delivering seaweed raw material X1,
The raw material for making seaweed X2 is allowed to fall into the raw material liquid tank 28.

In response to the continuous supply and fall 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 the mixture is stirred and mixed into seaweed raw material X2 having a desired concentration.

The blended seaweed raw material X2 is fed through the feed hose 32 to the subsequent seaweed cutting process by a feeding pump 30 that drives a motor 31.

In addition, the manual operation bundle 10 is used to store the first seaweed raw material X2 when the original seaweed raw material X1 is put into the raw material tank 1.
This is useful for artificially increasing the rotational feeding force of the seaweed raw material X1 by the screw feeder 5 during the preparation work or the final preparation work.

After 2 kl of seaweed raw material X2 or more is circulated and raised from the raw material liquid tank 28 to the auxiliary tank 50 in this manner, when the operation of the circulation pump 52 is stopped, the amount of water in the auxiliary tank 50 communicating with the raw material liquid tank 28 is The water level decreases and the liquid level in the raw material liquid tank 28 becomes balanced.

Therefore, the raw seaweed material X2 that has passed through the measuring device 53 during circulation is drained and dehydrated for a certain period of time via the measuring device 53, and concentrated into a semi-dehydrated seaweed raw material.

At this time, the weight of the entire scale 53 is electrically and mechanically detected by a differential transformer 55 that detects the height displacement, or a detection device such as a photo sensor or a non-contact relay. The degree of density of the seaweed material X2 with respect to the predetermined reference value determined is determined.

If the detected weight or the vertical displacement due to the weight is within the set reference value range (predetermined tolerance limit), the feed pump 3

The liquid is fed to the raw material liquid tank 43 of the nori sheeting machine 36 and used for a predetermined nori sheeting operation.

Further, if the detected weight or weight displacement deviates from the set standard value range, the manual operation bundle 10 is rotated depending on the weight or weight to supply the seaweed raw material X1, or the water supply pump 26 is activated. After controlling the supply amounts of seaweed raw material X1 and water Y by a method such as water supply, the seaweed raw material X1 and water Y are mixed again.

Using this nori raw material Xi as a base, the above-mentioned action is repeated again to obtain a nori raw material X2 having a desired concentration.

In addition, the rotational speed of the drive motor 20 is controlled to increase or decrease based on the concentration detection result of the seaweed raw material X2, which is useful for feeding the nori raw material X1 in a fixed amount by the screw feeder 5.
