Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an apparatus for continuously forming laver sheets of uniform thickness in a long or endless seaweed cage.

[Conventional technology and problems]

Currently, the automatic seaweed production equipment that is used to make seaweed sheets is one that creates regular-sized seaweed leaves one sheet at a time in a regular-sized seaweed cage, but in recent years,
Devices that use endless seaweed cages to continuously form sheets of seaweed are being developed, but the ones that have already been proposed include, for example, the one shown in Japanese Patent Application Laid-Open No. 102377/1983. Then, while a part of the endless seaweed cage is submerged in the water tank, the seaweed fronds injected into the zone between the top surface of the tank and the top surface of the submerged seaweed cage are scooped up from the tank. This is a device designed for escape running. Such devices have the following problems.

(a) Since the liquid prepared by the seaweed fronds is injected into the zone between the top surface of the aquarium and the top surface of the submerged seaweed cage, the mixed liquid may become unmixed again or the seaweed cell may migrate. Due to the rippling phenomenon of the water surface in the water tank, the thickness of the paper is not uniform.

(b) Since the back side of the seaweed cage is water, the floating seaweed leaves intervene on the back side from between the materials that make up the seaweed cage.
When the seaweed cage escapes from the water surface, it remains as seaweed legs, which causes major problems, such as tears, in the drying and peeling process.

[Purpose of invention]

The present invention was developed in response to these circumstances, and uses simple and rational means to facilitate the adjustment and uniformity of paper thickness, which had not been solved with the prior art, and to eliminate excessive It is an object of the present invention to provide a papermaking device for producing long dried seaweed in which no seaweed legs are produced.

[Structure of the idea]

The structure of the present invention that solves the problems of the conventional technology is as follows:
A concave opening with a planar shape approximately the same width as the width of the finished seaweed is formed at the upward end of the sloping bottom surface, and the continuously supplied mixture of seaweed leaves continuously overflows from the opening. A liquid tank is provided, and a filter belt conveyor whose upward traveling surface moves along the inclined bottom surface of the liquid mixture tank is provided below the bottom surface of the liquid mixture tank, and the filter belt conveyor and the liquid mixture tank are connected to each other. It is characterized in that a long or endless seaweed cage, which is accompanied by the movement of the filter belt conveyor, is sandwiched between the sloped bottom surface of the filter belt and the sloped bottom surface of the filter belt conveyor.

〔Example〕

The details of the embodiment will be explained below with reference to the drawings.
Reference numeral 1 denotes a machine frame, and at the top of one side of the machine frame 1, a liquid mixture tank 10 of seaweed leaves is arranged. The mixing tank 1
A filter belt conveyor 20 is provided at an angle below the filter belt 0, and a water receiver 30 is further provided below the filter belt conveyor 20. The above mixed liquid tank 1
As is clear from FIG. 1, the bottom of 0 is an inclined bottom surface 11 similar to the upward traveling surface 21 of the cloth belt conveyor 20, and the upward end has a concave planar shape in the center. is cut out to form an opening 12 having approximately the same width as the width of the finished seaweed. Further, inside the liquid mixture tank 10, a rectifying plate 13 is vertically disposed in a neutral manner, and furthermore, a supply pipe 14 for the liquid mixture of seaweed leaves faces the upper part of the liquid mixture tank 10.

In addition, the portions of the left and right side walls of the liquid mixture tank 10 facing the opening 12 are made of side walls 10a that are sandwiched to the width of the opening 12, as shown in FIG. Furthermore, although the green side 12a of the opening 12 is linear in FIG. 2, it can be made into a concave or convex arc shape to control the thickness distribution of the seaweed in the width direction. It is also possible. In the figure, 15 indicates the level of the liquid preparation, and 16 is an opening leading to an external pipe.

The filter belt conveyor 20 includes an endless filter belt made of woven fabric or non-woven fabric having suitable water-blocking properties and water filtration resistance performance, and a driving pulley 2.
3 and a guide pulley 24, and a long or endless seaweed cage 40 is sandwiched between the upward traveling surface 21 of the filter belt conveyor 20 and the inclined bottom surface 11 of the liquid mixture tank 10. , the seaweed cage 40 accompanies the movement of the filter belt conveyor 20.

In addition, the width of the seaweed cage 40 is determined by the width of the seaweed 40a to be cut.
It is wider than the width of the It goes without saying that the width of the filter belt conveyor 20 is also larger than the width of the dried seaweed 40a.

Furthermore, by making the driving pulley 23 have a variable rotation speed structure, the residence time of the nori leaf mixture can be adjusted, and the thickness of the nori leaf can be more easily adjusted, and the adjustable range can also be expanded. Can be expanded. The water receptacle 30 has a hopper shape, and a drain port 31 is provided at the bottom thereof.

[Effect]

Next, the operation will be explained based on the above embodiment. The filter belt conveyor 20 is driven in the direction of the arrow, and the seaweed cage 40 is caused to accompany this transition operation at the same speed in the direction of the arrow. On the other hand, from the supply pipe 14, a mixture of seaweed leaves having a concentration suitable for the thickness of the seaweed is continuously supplied into the mixture tank 10. The blended liquid in the blended liquid tank 10 overflows from the opening 12 onto the seaweed basin 40 and is collected one by one while staying there.
At this time, the liquid mixture is prevented from generating turbulent flow or swirling flow by the rectifying plate 13, and a uniform thickness of seaweed leaves is successively formed.

It affects the papermaking time and papermaking thickness. Specifically, the water level 15 in the mixed liquid tank 10, which determines the retention length of the mixed liquid in the papermaking action, is adjusted by the supply flow rate of the mixed liquid, as well as the amount discharged from the opening 16 to the external pipe line. and control.

Further, water in the nori leaf mixture that has passed through the surface of the seaweed basin 40, which also serves as the bottom of the opening 12, through the seaweed basin 40 and the upward traveling surface 21 of the seaweed belt conveyor 20 is transferred to the seaweed sheet conveyor 20. By falling on the back side of the going-back surface 22 of 20 and passing through to the front side, the residue adhering to the filter belt conveyor and the front side is washed away, collected in the water receiver 30, and discharged to the outside from the drain port 31.

The water contained in the seaweed leaves formed on the seaweed cage 40 from the opening 12 drips onto the upward traveling surface 21 of the filter belt conveyor 20 and during the diagonally upward movement of the seaweed cage 40. Preliminary dehydration flows,
Proceed to the next step, dehydration and drying.

The filtration belt conveyor 20 not only smooths the movement of the seaweed into the seaweed cages 40, but also limits the filtering speed of water in the seaweed leaf mixture during the papermaking process, allowing the mixture to temporarily stay there for a sufficient period of time. It plays an important role in making the papermaking process quiet and stable. In addition, the seaweed belt conveyor 20
By being in close contact with the back surface of the seaweed cage, it also has the effect of preventing so-called seaweed legs from becoming excessively large, which occur on the back surface of the seaweed cage.

[Effects] As described above, according to the present invention, the following effects can be obtained.

(a) It goes without saying that nori leaves can be continuously formed in a long or endless seaweed cage, and (b) the seaweed sheets can be blended by bringing the filter belt conveyor into contact with the bottom surface of the seaweed cage. The filtration rate of water in the liquid is limited, resulting in a stable papermaking process, which not only allows for nori papermaking with a uniform thickness and no unevenness, but also allows for nori papermaking to occur by intervening on the back surface through the gaps in the materials that make up the nori cage. To rationally prevent the occurrence of excessive seaweed legs and to produce seaweed with high commercial value.

(c) In addition to adjusting the concentration of the seaweed leaf mixture board, it is possible to easily cut laver of any desired thickness by adjusting the water level of the mixture tank.

(d) A seaweed cage is attached by a filter belt conveyor,
Since it assists the migration, it reduces the load on the nori cage, prevents the nori cage from sagging and stretching, and maintains the correct cutting action, further increasing the commercial value of nori and reducing the cost. The life of a long or endless seaweed cage can be maintained for a long time.

(e) The mixed liquid tank has a sloped bottom that is parallel to the upward traveling surface of the filter belt conveyor, so the mixed liquid storage capacity can be reasonably increased, and the mixed liquid can continuously overflow from the opening. Due to this overflow effect, an appropriate amount of the blended liquid is continuously supplied to the seaweed cage, making it possible to control sheet forming with uniform thickness.

(f) Unlike conventional technology, which involves pouring the mixed liquid into a water tank before making paper, papermaking is performed immediately while overflowing the mixed liquid in the mixed liquid tank. There is no adjustment and the paper forming efficiency is high.
