Description

[Detailed Description of the Invention] The present invention relates to an iron powder removal device in a seaweed production device.

The process of manufacturing seaweed generally involves mincing raw seaweed and cutting it into short pieces → washing with water → mixing the seaweed and water in a mixing machine → temporarily storing it in a stirring tank while stirring → drying it by cutting it with a seaweed machine. However, during this process, rust from machinery and iron powder adhere to the nori.

If such rust or iron powder gets mixed into the seaweed, it not only reduces the quality of the seaweed, but it is also unfavorable from a sanitary standpoint.As a way to remove this, permanent magnets are used. Sand and shells are removed from areas where the mixture of seaweed and water (generally referred to as mixed seaweed, hereinafter referred to as mixed seaweed) passes through, for example, on the way from the mixer to the stirring tank. This may be inside a so-called impurity removal device (see Figure 1) or a stirring tank (see Figure 2).

As shown in the diagram, the impurity removal device consists of a gutter made of stainless steel or galvanized steel plate with several partition plates installed in the middle, and while the prepared seaweed passes through each partition plate, impurities such as sand and shells are removed. Because it is heavy, it sinks to the bottom and cannot pass through these partition plates.

The stirring tank is a tank that temporarily stores the prepared seaweed, and the purpose of stirring is to prevent separation of seaweed and water.

However, in the method described above, since the permanent magnet is located at the bottom, not all of the mixed seaweed passes by the magnet, and the iron powder cannot be completely absorbed.

Furthermore, it was difficult to remove the adsorbed iron powder.

On the other hand, unlike the methods described so far, there is a method in which the magnetic adsorption force of the permanent magnet is weakened to make it easier to remove iron powder, but the ability to adsorb and remove iron powder in the mixed seaweed is also weaker. So it's not a very good method.

The present invention relates to a device that eliminates the above-mentioned drawbacks, and its gist is that a partition plate having a hollow portion is disposed in a channel through which the mixed seaweed overflows and passes through the gutter through which the mixed seaweed flows. Seaweed production, characterized in that the partition plate is provided with an opening that communicates with the outside of the flow path of the prepared seaweed, and an iron powder adsorbent made of an electromagnet or a permanent magnet is removably or fixedly inserted into the hollow part through the opening. This is an iron powder removal device in the equipment.

The present invention will be described in detail below with reference to the embodiments shown in FIGS. 3 to 5.

That is, partition plates 2 are installed at required locations in the gutter 1 through which the mixed seaweed A is distributed.
is installed.

The materials of the gutter 1 and the partition plate 2 are not particularly limited, but if they are made of a magnetically sensitive material such as ordinary steel, the particles emitted from the iron powder adsorber 3 and located around it. It is preferable to use a non-magnetic and corrosion-resistant material such as stainless steel or plastic, since the lines of magnetic force that should extend to the mixed seaweed portion form a closed circuit and do not work effectively.

The partition plate 2 has a top wall 2a, side walls 2b, 2c, and is open at the bottom 2d to form a hollow portion 2e.

In FIG. 3, a part of the gutter 1 is cut away to show the structure of the hollow part 2e.

The iron powder suction tool 3 is inserted into the hollow portion 2e from the lower opening 2d and attached by a fixing means (not shown).

In FIG. 4, an intermediate wall 2f is provided in the hollow part 2e to partition the hollow part 2g, and an opening 4, which is the entrance and exit of the iron powder suction tool, is provided in the side wall of the gutter 1 where the partitioned hollow part 2g is located. There is.

The iron powder suction tool 3 is inserted into the hollow part 2e through the opening 4 and attached, and then pulled out and removed.

Although FIGS. 3 and 4 typically show the partition plate 2 equipped with the iron powder suction tool 3, in general, in order to improve the effectiveness, as shown in FIG. A plurality of partition plates are provided to form a multi-stage system, and a partition plate 2 equipped with an iron powder suction tool 3 and a partition plate 7 not equipped with an iron powder suction tool are mixed to create a partition plate 2 equipped with an iron powder suction tool 3. They are placed in locations that are effective for removing iron powder.

In FIGS. 3 to 5, 5 indicates a pipe for transporting the blended seaweed from the blending machine, and 6 indicates a delivery port for sending the blended seaweed to the paper machine.

In both FIGS. 3 and 4, the iron powder suction tool may be attached in a manner that allows it to be moved in and out, or the electromagnet may be attached in a semi-fixed manner.

The choice of whether to use a permanent magnet or an electromagnet depends on the size and type of the device, but electromagnets make the device larger and more complex, but it does not require electricity to be applied when removing the adsorbed iron powder. There is an advantage that the iron powder can fall and be removed by itself if it is placed there.Permanent magnets do not have such an advantage, but a simple device is sufficient, and the iron powder can be removed by removing the permanent magnet. Each has its advantages and disadvantages.

Further, as shown in FIGS. 6 and 7, for example, a recess 8 for temporarily fixing iron powder is provided on the upper surface of the partition plate 2 equipped with the iron powder suction tool 3.
It is preferable to drill grooves 9.

As described above, according to the present invention, the partition plate 2 having the hollow portion 2e is arranged in the channel 1 through which the mixture of seaweed and water, that is, the prepared seaweed A, flows, and the flow path through which the mixed seaweed A overflows and passes. An opening 4 is provided which communicates from the hollow part 2a of the partition plate to the outside of the flow path of the prepared seaweed A, and an iron powder adsorption tool 3 made of an electromagnet or a permanent magnet is detachably attached or fixed to the hollow part 2e from the opening 4. Since it is inserted and installed, rust and iron powder present in the mixed seaweed can be efficiently removed, and the removal work can be facilitated.
